    Field of the Invention Mink slurry separation plant
    The present invention relates to a mink slurry separation system for use in mink houses, the plant comprising a lower part, the lower part comprising a fertilizer collection channel with an upper part, the upper part of the gutter in a cross section perpendicular to the longitudinal direction of the gutter having a first edge and a second edge, said edges extending longitudinally of the gutter,
    BACKGROUND OF THE INVENTION
    It is known from EP0276031 to separate, among other things, mink manure in solid and liquid form, providing a device comprising a container in the form of a gutter in which a net is located. The net is permeable to liquid, leaving the solid fertilizer lying on the top of the net, while the liquid fertilizer seeps through the net and into the bottom of the gutter. The net can be moved as a conveyor belt in the longitudinal direction of the gutter, whereby the solid part of the fertilizer can be carried away. The invention is an integrated separation plant for new installation in mink houses, among other things, but it does not solve the problems of existing scavenging plants, nor does it solve the known problems regarding odor nuisance and other risks.
    From EP0022596 it is known to separate the manure in solid and liquid form, providing a device comprising a foil with perforations in the center line of the foil for separating the liquid fertilizer from the solid fertilizer where the liquid fertilizer is discharged into a solid fertilizer. trench. The sheet supported by sheets and rolls is used only once, the sheet being rolled up on rolls after the fertilizer transport and subsequently disposed of. The invention is also an integrated separation plant for new installation in livestock stables, nor does it solve the problems of existing demolition plants, nor does it solve the known problems regarding the risks from gases.
    The following terms are used in the application: • solid fertilizer that is muddy and / or the solid part of manure (mixture of livestock urine and muck), and • liquid fertilizer that is eel (livestock urine, especially mink) and / or the liquid part of manure (mixture of livestock urine and muck).
    The genes involved are the following: • odor nuisances, as the liquid fertilizer of a pet smells strongly of ammonia, which has a pervasive, unpleasant odor, • risks of the effects of gases on humans and the respiratory system, since ammonia is both toxic and corrosive; and at high concentrations one can faint and become unconscious; • the evaporation of ammonia, since the deposition of the ammonia is probably close to the evaporation site, but the decay is not controllable, and thus the decay does not occur where desirable. The fallout can thus lead to changes in the surrounding nature which have a so-called 'tolerance limit', which is defined as the sensitivity of a natural area, and where no changes can be detected by the supply / load of, for example, nitrogen. Finally, it is not economical - especially not for the farmer - when nitrogen is dropped, as is the case when the nitrogen is taken up in the air, since the nitrogen can not be used as controlled fertilizer amount on arable land.
    The object of the invention
    It is thus the object of the invention to provide a mink slurry separation plant which, for example, can be retrofitted in connection with existing scavenging gutters and is thus capable of removing the odor nuisances, risks from gases and evaporation of ammonia from liquid fertilizers.
    Liquid fertilizer smells strongly of ammonia, as mentioned above, and this can cause odor nuisance, which arises, among other things, from the presence of liquid fertilizer in stripping systems in stables, and therefore liquid fertilizer must be in the system for as short a time as possible. Especially in mink houses, it is common to use so-called backwashing of the scavenging system, whereby there is also a risk that the colorless and toxic gas-like sulfur hydrogen formed in liquid fertilizer can enter the barn area, which can have a deadly output for mink as well as people, which is why these backwashes are made as rarely / as little as possible. Finally, there is the evaporation of ammonia, which results in a loss of fertilizer and thus a loss of value to the farmer, and the evaporation of ffa mink production is otherwise particularly high compared to other livestock production, since in mink production very protein rich feed, for example from fish , pigs and cattle.
    Description of the Invention
    According to a first aspect of the invention, the above stated object is achieved with a mink slurry separation system for use in mink houses, the plant comprising a lower part, the lower part comprising a fertilizer collection channel with an upper part, the upper part of the gutter in a cross-section perpendicular to the longitudinal direction of the gutter. is open and thus has a first edge and a second edge, said edges extending in the longitudinal direction of the gutter, as initially described and as described in the preamble of claim 1, wherein the plant further comprises an upper part, the upper part comprising an endless conveyor belt for collecting solid fertilizer, wherein the endless conveyor belt has an outer side and an inner side as well as a first edge and a second edge, said edges extending substantially parallel to the first edge and second edge of the lower part, and the conveyor belt further comprising a conveying side , and a return page, as well as a drive station, turning station and / or size a nursing station where the endless conveyor belt is permeable to liquid fertilizer and the return side of the conveyor belt constitutes a cover over the bottom part and thus covers at least part of the area between the first and second edges of the bottom part in the longitudinal direction of the gutter.
    This allows the upper part to be retrofitted to an existing set up and functioning well, and thus the mink slurry separation plant will be able to remove the odor nuisances, risks from gases and evaporation of ammonia from liquid fertilizers.
    In practice, the upper part comprising a conveyor belt in which the conveyor belt has a conveyor side and a return side uses the conveyor belt return side as a cover. In a cross section - perpendicular to the longitudinal direction of the mink slurry separation plant - the lid will follow the inner contour of the gutter, or at least the lid will not be horizontal. Depending on how the conveyor belt is suspended and supported, the position between the lower part, in the form of the bottom of the gutter and the upper part, in the form of the return side of the conveyor belt may vary, which, however, has no functional significance as long as the return side of the conveyor belt does not drag directly into or is in the significant contact with the bottom of the gutter and thus the liquid fertilizer.
    The endless conveyor belt is permeable to liquid fertilizers, the permeability being caused by openings in the conveyor belt of between 0.2 and 2.5 mm, preferably between 0.9 and 2.1 mm, further preferably between 1.2 and 1.8 mm. The entire conveyor belt may be of woven or molded cloth, where the desire for permeability may depend, among other things, on the local conditions of the mink houses in terms of temperature and operating conditions.
    In another aspect, the present invention also relates to a mink slurry separation system where the second edge of the upper endless conveyor belt has a greater distance from the second edge of the gutter than the first edge of the upper endless conveyor belt has from the first edge of the gutter.
    This makes it possible to use the mink slurry separation system in such a way that the endless conveyor belts of the conveyor line substantially perpendicular to the longitudinal direction of the conveyor belt extend further below the mink housing cages than is actually necessary for the system to function as intended. There may be several reasons for this desire, but in general it is a matter of fertilizer decay through the bottom of the mink cages, which can also be disposed of by a wider conveyor belt along this route rather than having to be removed from the ground or under the mink cages.
    The present invention also relates, in a third aspect, to a mink slurry separation system where at least one carrier is fixed on the outside of the conveyor belt and in a fourth aspect also a mink slurry separation plant where there is a movable between the outside of the conveyor belt and the at least one carrier. spacer. In a preferred embodiment, the spacer is constituted by a string or a strap.
    A carrier may, in its simplest form, be a body, for example, a ball dragged longitudinally at the bottom of the manure collection trough and which in this movement creates a flow in the collected liquid manure.
    This makes it possible, in part, to facilitate and contribute to the movement of the fertilizer on the transport side, but especially in a preferred embodiment to facilitate and contribute to the movement of the liquid fertilizer, where it at least one enters on the return side by means of a spacer. able to reach the bottom of the manure collection trench and here drag the manure with it in the direction of movement and towards the outlet of the trench, which will also minimize the liquid manure's stay in the trench and thus it will also reduce the odors caused by the liquid manure, and not least so the evaporation of ammonia from the fertilizer, which, by evaporation, loses fertilizer value.
    The present invention also relates, in a fifth aspect, to a mink slurry separation plant, in which at least parts of the carrier have a curved surface which substantially corresponds to the curvature of the gutter in a cross-section of the gutter.
    This allows for a more optimal contact surface between the carrier and the manure collection trough. In a preferred embodiment, the carrier is spherical, for example, of a resilient material such as foam rubber or the like, but in another preferred embodiment, the carrier could also be partially spherical to the portion intended for contact with the gutter.
    In an alternative embodiment, the carrier is merely a plate, for example, of rubber or the like, having a shape which substantially corresponds to gutter when the plate tugs at the bottom of the gutter. In a further alternative embodiment, the movable spacer may, for example, in the form of a strap, itself constitute a carrier, the spacer thus in contact with the liquid also creates movement in the liquid and in the direction in which the liquid is desired to move.
    The present invention also relates, in a sixth aspect, to a mink slurry separation plant, the plant further comprising a plurality of support brackets for / for the conveyor side of the endless conveyor belt.
    This allows the endless conveyor belt transport side to be supported between the driving, turning and tightening stations, or - if the driving and tightening station is located at the same end of the endless conveyor belt - between the driving / tightening station and the turning station, or - if turning and tensioning station is located at the same end of the endless conveyor belt - between the turning / tensioning station and the drive station.
    The support brackets may be longitudinal as well as transverse to the gutter, and may be wholly or partially rounded, plastic or other suitable material, and the support brackets may have rounded or flat surfaces on which the endless conveyor belt transport side is intended to slide.
    The present invention also relates in a seventh aspect to a mink slurry separation plant, the plant further comprising a plurality of support brackets for / for the transport side and return side of the endless conveyor belt.
    This makes it possible to support both the transport side and the return side of the endless conveyor belt between the driving, turning and tightening stations, or - if the driving and tightening station is located at the same end of the endless conveyor belt - between the driving / tightening station and the turning station, or - if the turning and tightening station is located at the same end of the endless conveyor belt - between the turning / tightening station and the drive station.
    The support brackets may also be longitudinal as well as transverse to the gutter, and may be wholly or partially rounded, plastic or other suitable material, and the support brackets may have rounded or flat surfaces on which the conveyor and return sides of the endless conveyor belt are intended to slide.
    The present invention also relates, in an eighth aspect, to a mink slurry separation system, in which at least one of the support brackets to / for the return side of the endless conveyor belt has an opening for passage of a carrier.
    This makes it possible to support both the return side and the outside of the conveyor belt while ensuring that the belt is in contact with the gutter. At the same time, it is possible that the carrier is also able to pass the shackles through the openings therein. Other shackles, for example every other shackle, can then ensure that the conveyor belt is held down by having the support on the inside of the return side.
    The support brackets may also be longitudinal as well as transverse to the gutter, and may be wholly or partially rounded, plastic or other suitable material, and the support brackets may have rounded or flat surfaces on which the conveyor and return sides of the endless conveyor belt are intended to slide.
    The present invention also relates, in a ninth aspect, to a mink slurry separation system, in which the support brackets are mounted on at least one of the edges of the lower part gutter.
    This makes it possible to mount the support brackets on the edge of the gutter that is most accessible, so that the mounting becomes fast, easy and most convenient. Depending on the conditions in the mink housing, the support brackets may also, or instead, be mounted on rafters and / or brackets at the cages.
    The present invention also relates in a tenth aspect to a mink slurry separation system where the endless conveyor belt drive station, turning station and / or tensioning station is mounted on a chassis, where at least one cleaning brush is also mounted on the chassis for cleaning the return side of the conveyor belt.
    The brush may be either rotary or stationary, and there may be one or more brushes on both the outside and the inside of the tape or on both sides simultaneously. If there are brushes on both sides of the tape, the brushes can be mounted opposite each other, so that they clean the tape from each side simultaneously. Stationary brushes may be mounted in brackets that are optionally spring loaded so that there is a permanent pressure from the brush on the belt. Rotating brushes can be driven by their own motor or via some form of power transmission (gear or belt drive) from the plant or drive station. Where the exterior cleaning of the tape prevents solid fertilizer from stopping the properties of the tape as permeable and prevents the internal cleaning and build-up of deposits on the rollers where the tape is conducted.
    In a preferred embodiment where the mink slurry conveyor belt has one or more carriers, at least on the outside of the conveyor belt, the brushes are bifurcated with a distance between the portions or with a recess where the distance / recess at least corresponds to the size of the carrier or strap. / cord with which it is fixed.
    This allows the conveyor belt to be cleaned after it has functioned as a conveyor side, that is, after the solid fertilizer has been removed from the outside of the conveyor belt and where any residual residues in the form of solid fertilizer residues can be advantageously removed immediately after the conveyor belt conveyor side is been to the conveyor belt return side. As the return side returns below the conveyor side, the liquid fertilizer will subsequently run through the conveyor side of the conveyor belt and thus run from the outside of the conveyor side to the inside, whereupon the liquid fertilizer will then drip down on the return side of the conveyor belt and here it will run from the inside to the outside to finally dry. in the underlying gutter.
    The present invention also relates in an eleventh aspect to a mink slurry separation plant, the drive station at least comprising a drive roller, the turning station at least comprising a turning roller and / or the tightening station at least comprising a throttle roller, and the mink slurry separation system further comprising at least one return roll, wherein the return roll is divided by a distance between the two parts or with a recess, the distance / recess of the return roll at least corresponding to the size / width of the carrier.
    This allows the conveyor belt to be carried with the carrier around the various stations in such a way that the drive roller, the turning roller and the tensioner roller only come into contact with the inside of the conveyor belt. Thus, it allows the carrier to not be pressed and ground as it is possible to pass unobstructed the return roll or return rolls, thus also preventing the belt from being lifted and the continuity of the belt rotation and speed otherwise disturbed by the carrier.
    The present invention also relates, in a twelfth aspect, to a mink slurry separation plant in which the manure collection channel of the lower part in the longitudinal direction of the channel, in use, is different from the horizontal.
    This allows the liquid fertilizer to run out of the gutter by itself and of course to run faster out of the gutter the greater the difference on the angle between the fertilizer collection gutter and the horizontal. Minimum possible time in the mink slurry separation plant, resulting in less evaporation and thus less odor nuisance as well as waste of liquid fertilizer.
    The liquid fertilizer runs into one or more channels, from which the liquid fertilizer is directed to one or more collection tanks / containers.
    The present invention also relates in a thirteenth aspect to a method for using mink manure separation plant according to any of the aforementioned aspects, the method having the following steps: • fertilizer is fed to the mink manure separation plant, and • the conveyor belt / upper part carries solid fertilizer away with a given speed, optionally in time intervals such that • solid fertilizer collection takes place on the endless conveyor belt transport side, while • liquid fertilizer runs through the conveyor belt's conveyor side and further down the conveyor belt's return side and finally down • into the fertilizer collection trench.
    This allows the mink slurry separation plant to function precisely as mink slurry separation plant, separating solid and liquid fertilizers and thus dividing, thereby removing odor nuisances, risks from gases and evaporation of ammonia from liquid fertilizers.
    The conveyor belt / top conveyor of solid fertilizer at a given speed, optionally in time intervals, may optionally be replaced by a conveyor at a constant speed, the conveyor belt thus running constantly. The faster the conveyor belt runs, the less time the solid fertilizer gets stuck in the conveyor belt, and the easier it is to clean / brush afterwards, whereby the permeability remains optimal and the liquid fertilizer is discharged as best as possible.
    The present invention also relates, in a fourteenth aspect, to a method for using mink slurry separation plant, the method comprising the following further steps: • the at least one carrier movably attached to the outside of the conveyor belt tugs between the belt and the gutter and draws the liquid fertilizer with it towards an outlet in the manure collection trench.
    This makes it possible to increase the influence of the transport speed of the liquid fertilizer without having to mount the gutter with a larger slope. At the same time, the carrier is pulled to the bottom, thus helping to clean the gutter and thus preventing impurities from growing in the gutter.
    The present invention also relates, in a fifteenth aspect, to a method for using mink slurry separation plant, the method further having the following steps: • the liquid fertilizer is discharged from the gutter via a duct system or via a pipe system and collected for further disposal / storage / use; solid fertilizer is transported away on the conveyor side of the conveyor belt and collected for further disposal / storage / use.
    This makes it possible to safely and safely collect as much liquid fertilizer as possible and the solid and non-hazardous fertilizer separately, since there will now only be an absolute minimum of liquid fertilizer left capable of evaporating from the remaining solid fertilizer. . For example, the liquid fertilizer can be stored in a conventional manure tank and solid fertilizer in a meeting place or in another suitable way.
    The present invention also relates in a sixteenth aspect to the use of mink slurry separation plant, according to any of the aforementioned aspects, for separating liquid and solid fertilizer from mink in mink houses.
    This makes it possible to use the mink slurry separation plant just as mink slurry separation plant for mink in mink houses, where solid and liquid fertilizers are separated and thus shared, by which odor nuisances, risks from gases and evaporation of ammonia from liquid fertilizers are accommodated.
    The present invention also relates to a mink slurry separation system, wherein the conveyor belt comprises at least one brush for cleaning the underside of cages in mink houses. Such a brush may be fixed to the edge of the conveyor belt and thus may be pulled along with and under the cages of the mink housings. This makes it possible to regularly clean the underside of the cages in the mink houses, or continuously, which prevents, among other things, fertilizer residues from sticking to the cages' bottom, which can otherwise be difficult to clean. Among other things, a brush can also remove fertilizer residues before they fall to the ground / under the mink cages, from which fertilizer residues must of course also be removed.
    The brush can be mounted on the conveyor belt by means of a bracket, for example a height adjustable bracket which can adjust the brush to the correct height, which can vary from mink housing to mink housing. In addition, the brush can be mounted on a bracket where the part of the brush closest to the conveyor belt can rotate about an axis which is substantially vertical, while the part of the brush which is farthest from the conveyor belt and thus farthest below the cages , can rotate at a substantially horizontal plane and at a given angle, for example 45 degrees around the substantially vertical axis of rotation of the brush. With such a rotatable stationary brush it is possible to achieve that a larger part of the brush passes the parts of the undersides of the cages with which the brush comes into contact. Among other things, fertilizer residues and feed residues can grow firmly to the bottom of the cages, which means that over time, the cages become even more difficult to clean, which is prevented with a brush as mentioned. A rotary brush type is also an option in which the brush is driven around, advantageously in a direction of rotation such that it is a counter brush and not a counter brush, as the conveyor belt is moved back and forth across the gutter.
    Such a solution with a brush that brushes under the cages can advantageously be applied to a conveyor belt that alternates one way or the other and thus not rotated like a traditional conveyor belt traveling one way only. However, one or more such brushes may also be mounted on a conveyor belt which is operated '' traditionally '', that is, operated alone in one direction. A conveyor belt with one or more such brushes may advantageously comprise an reinforced edge or reinforced region where a brush is mounted to the conveyor belt. Of course, this is only necessary in the event that the conveyor belt does not have the necessary rigidity in the belt as such. Such a stiffener can be rigid and not flexible, thus requiring a back and forth movement of the belt, while a more flexible and flexible stiffener, for example a rubber stiffener, will allow both stiffener and brush to be carried with the conveyor belt at both the drive station and at turning station.

    Detailed description of the invention
    A mink slurry separation system for use in mink houses according to the invention is shown in Figures 1-8.
    Figure 1 shows a mink slurry separation system 1, where the system 1 comprises an upper part 2 and a lower part 3.
    The upper part 2 comprises an endless conveyor belt 4 for solid fertilizer collection, the endless conveyor belt 4 having a first edge 5 and a second edge 6, as well as an outer side 7 and an inner side 8. The conveyor belt 4 further comprises a transport side 9 and a return side 10 ( see, inter alia, in Figure 2), as well as a drive station 11 and a turning station 12A. Figure 1 also shows a tightening station 12B located in the immediate vicinity of the drive station 11. Another possibility could be that the turning station 12A and the tightening station 12B were in close proximity to each other and thus at the same end of the slurry separation system 1, or another possibility. could be that turning station 12A and tightening station 12B could be built together in one unit. One or more of the latter drive station 11, turning station 12A and / or tightening station 12B is mounted on a chassis 17.
    In Figure 2, it is seen that the bottom part 3 comprises a fertilizer collecting duct 13 for collecting liquid fertilizer, the upper part of the gutter 13, in a cross section perpendicular to the longitudinal direction of the gutter 13, being open and having a first edge 14 and a second edge 15, where the said edges 14, 15 extend longitudinally of the groove.
    The endless conveyor belt 4 is permeable to liquid manure, by which the manure collection trough 13 is to collect and divert the liquid manure to collection tanks or the like.
    The first edge 5 and second edge 6 of the endless conveyor belt extend substantially parallel to the first edge 14 and second edge 15 of the lower part, and thus the return side 10 of the conveyor belt constitutes a cover over the lower part 3. The return side 10 thus covers a large part of the area which is between the first edge 14 of the base member and the second edge 15 in the longitudinal direction of the channel.
    It is also possible that the mink slurry separation system 1 comprises an endless conveyor belt having a second edge 6, the edge 6 having a greater distance ffa the second edge 15 of the bottom part than the endless conveyor belt's first edge 5 from the first edge 14. This will allow a larger fertilizer collection area, as a wider conveyor belt 4 will be able to reach further below the mink cages in the mink houses.
    Figure 3 shows a mink slurry separation system 1 - without conveyor belt 4 - from which it can be seen that the system 1 also comprises a number of support brackets 16 for the endless conveyor belt transport side 9. Figure 4 also shows how the conveyor belt's return side 10 forms a lid over the lower part 3. Support buoy Here, the brackets 16 are shown mounted on both edges 14, 15, which, for bending reasons, are the most stable embodiment of this type of support brackets 16, but it will also be possible to mount the brackets 16 only on one of the edges 14 and 15 or alternately on one first edge 14 and second edge 15.
    Figure 5 also shows a mink slurry separation system 1 - without conveyor belt 4 - from which it can be seen that the system 1 can also comprise a number of support brackets 16 for both the transport side 9 of the endless conveyor belt and for the return side of the endless conveyor belt 10. It also shows how The return side 10 of the conveyor belt covers the lower part 3. The support brackets 16 are shown mounted here on only one of the edges 14 of the gutter, which could also have been the other edge 15. This embodiment of support brackets 16 is sufficiently stable, since the support of the support brackets 16 for the return side 10 of the conveyor belt is supported by the first edge 14 of the gutter or alternatively second edge 15. Of course, it will also be possible to mount the support brackets 16 on both of the edges 14 and 15 of the gutter.
    The support brackets 16 are mounted / mounted perpendicular to the longitudinal direction 18 of the mink slurry separation system (see Figure 5), which will be most obvious, but the support brackets 16 may also be mounted / mounted at an angle different from the perpendicular to the length of the mink slurry separation system 18. perpendicularly mounted on the longitudinal direction 18 of the mink slurry separation system, however, the support brackets 16 will have to assume a longer and different ridge shape to maintain the shape and function of the conveyor belt.
    It is also possible to design the support brackets 16 as curved / curved shelves where one or two of one another is mounted / affixed to one edge 14 or the other edge 15 of the gutter and the support brackets / shackles are open in the side opposite the mounting side. advantageously with a side guide / side stop such that the conveyor belt 4 is unable to extend beyond the free ends of the support bend / shelves.
    The endless conveyor belt drive station 11, turning station 12A and / or tightening station 12B is mounted on a chassis 17, at least one cleaning brush 19 for cleaning the return side of the conveyor belt 4 is also mounted on the chassis 17. Examples of brush arrangements are shown in Figure 7. and Figure 8, where the brushes 19 shown are rotating brushes 19 mounted on the chassis 17. The brushes 19 could be stationary, or there could be both stationary and rotating brushes 19 together for the cleaning of the conveyor belt where the brushes 19 could be positioned opposite one another. or in a completely different arrangement not shown.
    The example shown in Figure 7 and Figure 8 shows brushes located on both sides of the endless conveyor belt 4 where the brushes 19 are mounted opposite each other so that they clean the belt 4 from each side simultaneously. Rotating brushes 19 can be driven by their own motor or via some form of power transmission from the plant or drive station. With this cleaning method, where the external cleaning of the belt prevents solid fertilizer from stopping the properties of the belt as permeable, the internal cleaning prevents the build-up of deposits on the rollers where the belt is guided, thereby ensuring a fully functional plant.
    In a preferred embodiment in which the mink slurry conveyor belt 4 has one or more carriers 20, at least on the outside of the conveyor belt 7, the brushes 19 are two-part with a distance between the parts or with a recess where the distance / recess at least corresponds to the size of the carrier The mink slurry separation plant 1 according to the invention is thus capable of separating liquid manure from solid manure, where the manure comes from mink in mink houses and where the liquid manure is discharged from the gutter 13 via (not shown) duct systems or pipe systems and is collected in one or several tanks for further disposal / storage / use, while the solid fertilizer is carried away on the conveyor side 9 of the conveyor belt 4 and collected at the end of the conveyor belt 4 for further disposal / storage / use.
    Figure 9 shows a mink slurry separation system 1 in perspective as described in Figure 1, but with a single carrier 20 shown on the outer side 7 and conveyor side 9 of the conveyor belt.
    Figure 10 shows a cross-section through a mink slurry separation system 1 as described in Figure 2, but where a carrier 20 is shown on the outer side 7 and return side 10 of the conveyor belt, and where the carrier 20 hangs at a spacer 21 and tugs along the manure collection channel 13.
    Figure 11 shows a cross-section through a mink slurry separation system 1 - with conveyor belt 4 - and with support brackets 16 for the conveyor side 9 of the endless belt as described in Figure 4, but where a carrier 20 is shown on the outer side 7 and return side 10 of the conveyor belt and where the carrier 20 hangs. in a spacer 21 and trailing along the manure collection trough 13.
    Figure 12 shows a cross-section through a mink slurry separation system 1 - with conveyor belt 4 - and with support brackets 16 to the conveyor end 9 and return side 10 of the upper end as described in Figure 6, but where a carrier 20 is shown on the outer side 7 and return side 10 of the conveyor belt, and the carrier 20 hangs at a distance 21 which can pass in an area about the center of the support 16 and thus can drag along the manure collection trough 13.
    Figure 13 shows a mink slurry separation system 1 in perspective without a conveyor belt and so that drive roller 22, reversing roller 24 and return roller 25 and supporting brackets 16, with support for the return side and outside of the conveyor belt 16A, support for the return side and inside of the conveyor belt 16B and support for the conveyor side and inside 16C are visible. As can be seen in the figure, the support brackets 16 are alternating with support for the return side of the conveyor belt and outside 16A which help to hold the belt up and support for the return side of the conveyor belt and inside 16B which helps to hold the belt down.
    FIG. 14 shows an endless conveyor belt 4 with carrier 20 and spacer 21 and an example of positioning drive roller 22, tensioner roller 23 and turning roller 24 and return running rollers 25. The position of the carrier on the outside of the belt 7 shows that the carrier 20 is wedged between the conveyor belt 4 and return rollers 25, which explain the design of both return rollers 25 and support brackets 16 shown in Figure 13 and further described in Figures 15-17.
    Figure 15 shows a support bracket 16, with support for the return side and outer side 16A of the conveyor belt, the support not being continuous but two-piece, so as to ensure that a carrier 20 and its spacer 21 can pass in an area around the center of the support 16A. In addition, the support bracket 16 has a support for the conveyor side 16C of the conveyor belt, which is also a structural advantage, since the support bracket 16 thus constitutes a unit and not several separate parts.
    Figure 16 shows a support bracket 16, with support for the return side of the conveyor belt and the inner side 16B, where the support is continuous and thus ensures that the conveyor belt 4 is held down. In addition, the support bracket 16 has a support for the conveyor side 16C of the conveyor belt. The support bracket 16 is thus also a unit.
    FIG. 17 shows an example of a return roller 25, the return roller comprising a shaft 25A and two abutment surfaces 25B, there being a distance 26 or a recess 26 between the abutment surfaces 25B allowing passage of the carrier 20 and the spacer 21.
    The invention is not limited to the above-mentioned embodiments which merely serve to clarify the preferred embodiments of the invention. It is thus clear that, after studying this writing, one skilled in the art will be able to carry out variants of the invention which are not described in detail in this publication.
