    DEVICE FOR DRYING DRY GOODS
    FIELD OF THE INVENTION
    The present invention relates to a device for drying of drying material, in particular of hay, the device comprising a fan and a dehumidifier with an evaporator, a condenser and a compressor.
    STATE OF THE ART
    In the drying of drying material, especially hay, which can be used in agriculture as an ideal feed for cattle, it is known to dehumidify air and to blow through the drying material. For this purpose, the material to be dried is typically placed in a ventilation box. The air is sucked in via a fan, supplied to a dehumidifier and then fed by means of the fan to the drying material to be dried or injected into the ventilation box.
    It is known from the prior art, for the arrangement of fan and dehumidifier own space-forming structure, preferably with separate rooms for fan and dehumidifier provided. Such a space-forming structure is e.g. in a building that the
    Ventilation box includes, integrates or may constitute a separate building.
    However, such a space-forming structure designed in the establishment of relatively lengthy and costly. In addition, it is difficult to seal the space-forming structure such that no air is lost to the outside, especially not when transporting the air from the dehumidifier to the fan. Finally, the space-forming structure can be changed hardly or only with great effort. Accordingly, it is difficult to convert the fan and dehumidifier to larger, more powerful devices, which retrofitting is particularly necessary if the ventilation box to be increased or additional ventilation boxes to be used for drying.
    OBJECT OF THE INVENTION
    It is therefore an object of the present invention to provide a device for drying of drying material available, which avoids the disadvantages mentioned above. The device according to the invention should in particular be quickly and inexpensively buildable, avoiding air loss to the outside and allow easy conversion or upgrade of fan and / or dehumidifier.
    PRESENTATION OF THE INVENTION
    Core of the present invention to solve the above problems is to arrange the fan and the dehumidifier each in a portable container and to fix. The containers are preferably those which are commonly used today in transport and which can be transported by truck. This enables a simple, inexpensive and safe transport and the fastest possible installation at the desired location. The transport is therefore particularly simple and inexpensive, since only an ordinary truck to transport the respective container with the fan or the dehumidifier is necessary.
    In addition, due to their stability - the containers are usually made of metal - the containers can be easily arranged on top of each other at the desired location, so that an enormously space-saving device can be realized. This arrangement can be done in particular by means of a crane or a forklift.
    Since the dehumidifier and the fan occupy a defined spatial position in the respective container, it is ensured that after arranging the container one above the other or in an operating state of the device, a desired defined spatial position of fan and dehumidifier is given to each other.
    In particular, the cumbersome, tedious and expensive construction of your own building for the fan and the dehumidifier can thus be omitted. In addition, it is easily possible to replace the dehumidifier and / or the fan. For this purpose, the containers are separated again, and it is the desired container replaced by a container with a new, possibly larger or more dimensioned dehumidifier or fan. In and out of the container, in turn, make it as easy as possible with an ordinary truck. For moving the containers at the place of installation, it is again sufficient e.g. a crane or a forklift.
    It is therefore in a device for drying of drying material, especially of hay, the device comprising a fan and a dehumidifier with a
    Evaporator, a condenser and a compressor, according to the invention provided that the fan is arranged and fixed in a transportable first container to ensure a transport of the first container a defined spatial position of the fan in the first container that the dehumidifier in a portable second container is arranged and secured to ensure a defined spatial position of the dehumidifier in the second container during transport of the second container, and that in an operating state of the device one of the two containers disposed on the other and, preferably releasably, is fixed to a defined spatial Ensure the position of the fan and the dehumidifier to each other. That the position of the fan relative to the first container is fixed and also the position of the dehumidifier to the second container. Since the containers are stacked and joined together in the operating state, the position of the fan and the dehumidifier is thus fixed to each other in the operating state, this position can be predefined by appropriate arrangement of the fan and dehumidifier in each container.
    Preferably, the containers are bolted together for releasable attachment. For many applications, it is necessary to blow the dried air from below into a ventilation box in which the drying material to be dried, in particular hay, is arranged. In many cases, the ventilation box is located adjacent to or adjacent to the containers. In order to be able to supply the dried air in a structurally simple manner, in particular by means of at least one air duct with the fan in the region of a bottom of the ventilation box, it is provided in a preferred embodiment of the device according to the invention that in the operating state of the device second container is disposed above the first container. This is because the fan is already at about the desired low (floor) level at which the air is to be supplied to the ventilation box. Furthermore, so in the said application, a recirculation mode can be easily realized, since air escaping from an upper region of the ventilation box, with structurally simple measures, in particular by means of at least one further air duct, the dehumidifier can be supplied. This is because the dehumidifier is already at about the desired elevated level at which the humidified air from the ventilation box flows.
    Typical dimensions of a container range from 3.5 m to 6.1 m in length, from 2 m to 2.5 m in width and from 1.9 m to 2.7 m in height. In order to achieve a particularly compact and space-saving design particularly in containers with identical or approximately identical dimensions, in particular as regards length and width, it is provided in a preferred embodiment of the device according to the invention that the containers are arranged substantially congruently one above the other in the operating state of the device are.
    In a preferred embodiment of the device according to the invention, it is provided that in the first container, a first opening is provided and in the second container, a second opening, wherein the two openings are arranged one above the other in the operating state of the device to a first transition for a fluidic connection between the train both containers. Thus, it is not necessary to provide a separate air duct for the transport of the dried air from the dehumidifier to the fan, which greatly simplifies the construction of the device according to the invention.
    The use of containers is also advantageous because conventional containers generally have a relatively good tightness or can be completely sealed with little effort. In principle, by the direct arrangement of the two openings one above the other one hand and the rest of the one container on the other hand, a satisfactory for many cases, tightness of the first transition to the outside can be guaranteed. To further improve this tightness, it is provided in a preferred embodiment of the device according to the invention that at least one seal is provided to seal the first transition to the outside, in particular airtight.
    As already stated, the dried air from the fan is ultimately blown to the drying material to be dried, in particular hay. To transport this air away from the first container, an air channel is provided in many applications, which connects for reasons of space in the region of a side wall of the first container. For example, it may occurrences that due to the local conditions of the first container must be positioned so that only a relatively small gap between the side wall and a wall of an adjacent building is available for the air duct in the region of the first container. In particular, in such cases, it is advantageous if a discharge direction, along which the air is blown from the fan, as parallel as possible to a direction along which the outflowing air must move in the air duct at least in the first container or along which the air duct in the area of the first container away from this. Otherwise, there would be a backflow of air in the air duct or the amount of air discharged per unit time would be reduced for a given performance of the fan. Therefore, it is provided in a preferred embodiment of the device according to the invention, that the arrangement of the fan in the first container is such that a blow-out, along which air is blown out by means of the fan, with a longitudinal axis of the first container and / or a side wall of the first container an angle of 15 ° to 60 °, preferably from 40 ° to 50 °. That The arrangement of the fan in the first container or the discharge direction may be transverse to a longitudinal axis of the first container, in particular along a diagonal of a base of the first container.
    By such a rotated arrangement of the fan, it is also possible to easily accommodate very large fans with an at least partially largest width, which is greater than the width of the first container in the first container. In principle, this of course also applies analogously to an at least sectionally largest length of the fan, which is greater than the length of the first container.
    Analogous to this arrangement of the fan in the first container, which is optimized with regard to the air flow, the arrangement of the dehumidifier in the second container can also be optimized with regard to the air flow. In many applications, the air is supplied to the dehumidifier through an opening in a side wall of the second container. The direction of the incoming air may preferably be normal to the side wall of the second container and / or to a longitudinal axis of the second container and / or to a longitudinal axis of the first container - the latter in particular when the containers are arranged substantially congruently one above the other. It is therefore provided in a preferred embodiment of the device according to the invention that the arrangement of the dehumidifier in the second container is such that a flow direction along which in the operating state of the device air by means of the fan is sucked by the dehumidifier on the shortest path, with a longitudinal axis of the second container and / or with a longitudinal axis of the first container and / or with a side wall of the second container at an angle of 15 ° to 90 °. The shortest path typically defines the shortest connection between the evaporator and the condenser of the dehumidifier.
    In order to take into account the mentioned possible different arrangements of the fan in the first container and always allow easy connection of an air duct, it is provided in a preferred embodiment of the device according to the invention that a venturi is provided, seen in a discharge direction to the fan connected, wherein along the blow-out direction air is blown out by means of the fan and wherein the venturi forms a dense, in particular airtight, second transition for the air from the fan to the outside, wherein the venturi forms an outlet for an air duct at an outer end.
    As already described, it may be necessary in typical applications that the air duct between the side wall of the first container and a wall of a building must be performed. Of course, situations are also possible where there is no space at the side of the side wall, but only in the area of a rear wall of the first container. Finally, situations are possible where both in the area of the side wall and in the back wall in each case a limited space for the air duct is available. In all these cases, optimal flow conditions for the outflowing air can be achieved with appropriate design of the air duct and of at least one corresponding opening in the side wall and / or the rear wall of the first container. It is therefore provided in a preferred embodiment of the device according to the invention that the second transition passes through a side wall and / or a rear wall of the first container.
    In order to achieve particularly favorable flow conditions of the outflowing air, wherein the highest possible amount of air can flow out per time, it is provided in a particularly preferred embodiment of the device according to the invention that a clear cross section of the air funnel between a beginning, with which the air vent to the fan adjoins, and widened the outer end of the air funnel. A backflow of air can be effectively prevented in this way.

    WAYS FOR CARRYING OUT THE INVENTION
    In Fig. 1, a device according to the invention is shown schematically in axonometric view. The device comprises a transportable first container 6, in which a fan 1 (indicated by dashed lines in FIG. 1) is arranged and fastened in a defined spatial position. Furthermore, the device according to the invention comprises a transportable second container 7, in which a dehumidifier 2 (see Fig. 5) is arranged and fixed in a defined spatial position. In the exemplary embodiment shown, the second container 7 is arranged above or on the first container 6, wherein two sides of the second container 7 are substantially flush with two sides of the first container 6. Thus, a spatially defined arrangement of the fan 1 to the dehumidifier 2, in particular in an operating state of the device, ensured. Preferably, the second container 7 is screwed to the first container 6 in order to realize a releasable attachment.
    The containers 6, 7 are made of metal and correspondingly stable to allow the space-saving stacking. The stacking can be done for example by means of a crane (not shown) or a forklift (not shown).
    The containers have common dimensions that allow easy transport by truck. Typical dimensions of the containers 6, 7 are in the following ranges: from 3.5 m to 6.1 m for a length 24 of the first container 6 and for a length 27 of the second container 7, respectively; from 2 m to 2.5 m for a width 25 of the first container 6 and for a width 28 of the second container 7; and from 1.9 m to 2.7 m for a height 26 of the first container 6 and for a height 29 of the second container 7. An overall height 32 is given by the sum of the heights 26 and 29. The length 24 is thereby measured along a longitudinal axis 12 of the first container 6, the length 27 along a longitudinal axis 16 of the second container. 7
    As can be seen in Fig. 1, the dimensions of the two containers 6, 7 need not be identical. In the illustrated embodiment, the second container 7 is slightly smaller than the first container 6 executed in all dimensions, resulting in particular a width difference 40 results. Such a width difference 40 would of course also be possible with a second container 7, which is the same length as the first container 6 (indicated by dashed lines in Fig. 1). Moreover, the widths 25, 28 and / or the heights 26, 29 may be the same size. The concrete dimensions of the respective container 6, 7 are mainly due to the dimensions of the fan 1 or the dehumidifier 2 to be accommodated.
    To - e.g. for maintenance purposes - to have easy access to the dehumidifier 2, the second container 7 has two access doors 10 arranged one above the other. Analogously, the first container 6 has an access door 10 to allow easy access to the fan 1.
    On a front side 41 of the first container 6, a control unit 33 and frequency converter 34 are further arranged, by means of which the fan 1 and the dehumidifier 2 can be controlled. Accordingly, in the second container 7 from the inside to the outside guided connectors (not shown) are provided to produce an electrical connection between the dehumidifier 2 and frequency converter 34 and control unit 33 for the purpose of supplying energy to the dehumidifier 2 and for controlling the dehumidifier 2.
    The fan 1 serves to dehumidify air, which is characterized in Fig. 1 as incoming air 38 by means of an arrow to suck through the dehumidifier 2 and the air dehumidifier 2 dehumidified air ultimately to be dried drying material, especially hay to blow , In this case, the material to be dried can be arranged in a ventilation box (not shown).
    In the exemplary embodiment shown, the incoming air 38 passes via an air inlet surface 30 in a side wall 17 of the second container 7 into the dehumidifier 2. In the exemplary embodiment shown, the direction of the incoming air 38 is essentially normal to the (plane of) the side wall 17 ,
    The dehumidifier 2 has an evaporator 3, in which refrigerant (not shown) is vaporized by the heat of the sucked air, cf. As a result, the sucked air is cooled below the dew point, and water condenses on the cold surface of the evaporator 3, from where it runs off or drips. Furthermore, the dehumidifier 2 has a condenser 4, in which the refrigerant condenses and thereby releases latent heat. In this way, the condenser 4 can be used as a heat source for heating the dehumidified air, in which the air, after it has passed the evaporator 3 and has been dehumidified, is also sucked through the condenser 4 along a flow direction 15.
    The flow direction 15 is given by the shortest path from the evaporator 3 to the condenser 4. In the illustrated embodiment, the evaporator 3 and the condenser 4 extend along parallel planes which are parallel to the side wall 17 and to which the flow direction 15 is normal. The flow direction 15 is not only normal to the side wall 17, but also on the longitudinal axes 12, 16th
    The flow direction 15 is thus parallel to the direction of the incoming air 38 in the embodiment shown, which guarantees optimum flow conditions. Generally, the dehumidifier 2 may be arranged according to the invention in the second container 7, that the flow direction 15 with an axis 12 and / or the longitudinal axis 16 and / or the side wall 17 forms an angle of 15 ° to 90 °.
    Moreover, the dehumidifier 2 includes a compressor 5 to compress the refrigerant evaporated in the evaporator 3. Since the compressor 5 gives off heat in this case, the compressor 5 is also suitable as an additional heat source, which can also be arranged conveniently between the evaporator 3 and the condenser 4, without significantly affecting the flow of air from the evaporator 3 to the condenser 4, see FIG. 5 ,
    To allow the dried air to flow to the fan 1, a first transition 8 is provided. This is formed by an opening in the second container 7 and an opening in the first container 6, which openings are arranged one above the other, when the two containers 6, 7 in a certain, provided for the operating state of the device arrangement above each other, as shown in FIG. 1 is shown by way of example. Here is shown in the
    Embodiment arranged one of the two openings in a base of the second container 7 and the other of the two openings in a top surface of the first container. 6
    The first transition 8 represents a fluidic connection between the two containers 6, 7, wherein already by the direct arrangement of the two openings one above the other hand and the rest of the second container 7 on the first container 6 on the other hand satisfactory for many cases tightness of the first transition 8 is guaranteed to the outside.
    In order to further improve this tightness, a seal 9 is provided in the embodiment shown, in order to seal the first transition 8 to the outside, in particular airtight. The seal 9 may in principle be arranged in one of the two containers 6, 7, in both containers 6, 7 or between the two containers 6, 7. In the illustrated embodiment, the seal 9 is arranged at least in the second container 7, cf. Also Fig. 5. Preferably, the seal 9 is made of an elastic material, in particular rubber material. It is thus ruled out that an air 39 flowing from the second container 7 into the first container 6 can unintentionally flow outward in the region of the first transition 8.
    The air 39 is sucked by the fan 1, which is designed in the embodiment shown as driven by an electric motor 36 centrifugal fan, from the second container 7 in the first container 6. As already stated, the dried air from the fan 1 is finally blown to the drying material to be dried, in particular hay. To transport this air from the first container 6 away an air channel 21 is provided in most applications. Depending on the available space or according to the circumstances at the place where the container 6, 7 are placed, different arrangements of the air duct 21 may be necessary. For example, it may occurrences that due to the local conditions of the first container 6 must be positioned so that only a relatively small gap between a side wall 14 of the first container 6 and a wall of an adjacent building available for the air duct 21 in the region of the first container 6 stands. In particular, in such cases, it is favorable if a discharge direction 11, along which the air is blown out from the fan 1, runs as parallel as possible to a direction along which an outflowing air 35 in the air duct 21 must move or at least in the region of the first container 6 along which the air channel 21 runs in the region of the first container 6 away from this. Otherwise, there would be a backflow of air in the air duct 21 or the amount of air discharged per unit time would be reduced at a given power of the fan 1. Therefore, it is provided according to the invention that the arrangement of the fan 1 in the first container 6 is such that the discharge direction 11 with the longitudinal axis 12 of the first container 6 and / or the side wall 14 of the first container 6 an angle of 15 ° to 60 °, preferably from 40 ° to 50 °. That the arrangement of the fan 1 in the first container 6 or the discharge direction 11 may be transverse to the longitudinal axis 12 of the first container 6, in particular along a diagonal 37 of a base 13 of the first container. 6
    By such a rotated arrangement of the fan 1, it is also possible, very large fans 1 with an at least partially largest width, which is greater than the width 25 of the first container 6, easily accommodate in the first container 6. In principle, this of course also applies analogously to an at least sectionally largest length of the fan 1, which is greater than the length 24 of the first container 6.
    In order to take into account the possible different arrangements of the fan 1 in the first container 6 and always allow easy connection of the air duct 21, a venturi 18 is provided according to the invention, which is seen in the discharge direction 11 with a beginning 23 directly connected to the fan 1 , wherein the air funnel 18 forms a dense, in particular airtight, second transition 19 for the air from the fan 1 to the outside and at one outer end 20 forms a connection for the air channel 21.
    The air channel 21 may be configured differently depending on the application. As already described, it may be necessary in typical applications that the air channel 21 between the side wall 14 of the first container 6 and a wall of a building must be performed. In this case, the second transition 19 passes through the side wall 14, which is illustrated schematically in FIG. 3. The air funnel 18 connects the fan 1 with a
    Air outlet opening 31 which is arranged in the side wall 14 of the first container 6. The air channel 21 correspondingly at the outer end 20 of the venturi 18 at this in the region of the air outlet opening 31 at.
    However, situations are naturally also possible where no space is available laterally of the side wall 14, but only in the region of a rear wall 22 of the first container 6. In this case, which is illustrated schematically in FIG. 2, the second transition 19 passes through Rear wall 22. In this case, the venturi 18 connects the fan 1 with the air outlet opening 31, which is arranged in this case in the rear wall 22 of the first container 6. The air channel 21 in turn connects at the outer end 20 of the venturi 18 to this in the region of the air outlet opening 31.
    Finally, situations are possible where both in the region of the side wall 14 and in the region of the rear wall 22 of the first container 6 each have a limited space for the air channel 21 is available. In this case, which is illustrated schematically in Fig. 4, passes through the second transition 19 both the rear wall 22 and the side wall 14. Accordingly, two separate air outlet openings 31 may be provided in the side wall 14 and the rear wall 22 or -As in the embodiment of Fig. 4 - a large air outlet opening 31, which extends in sections in both the side wall 14 and in the rear wall 22. The air funnel 18 connects the fan 1 with the air outlet opening 31 in the region of the rear wall 22. The air outlet opening 31 in the region of the side wall 14, however, is penetrated by the air funnel 18 far enough that the outer end 20 of the air funnel 18 is substantially flat and flush with the rear wall 22 completes. The air duct 21 in turn connects to the outer end 20 of the venturi 18 at this.
    In all these cases, with appropriate design of the air funnel 18 and the air outlet opening (s) 31 optimal flow conditions for the outflowing air 35 can be achieved. Particularly favorable conditions are present when a clear cross-section of the air funnel 18 widens between its beginning 23 and its outer end 20, as illustrated in particular in the exemplary embodiments of FIGS. 2 and 4.
