    The invention relates to a heating device with a combustion device, which has a combustion chamber, a conveying device for lumpy and / or dusty conveyed, which has an outlet opening into the combustion chamber or an inlet which is arranged below the combustion chamber, wherein the conveyor means a first screw conveyor and a rotary valve.
    For the promotion of lumpy kiln, such. Wood chips, it is already known from the prior art, for example the AT 501 790 A1, to combine a screw conveyor with a rotary valve. According to this AT-A1, the cell wheel has only one or two cells each of maximum size as a function of the size of the rotary valve. On the housing of the rotary valve is a digital position sensor and the cam a cam with a cam arranged, which makes it possible to detect depending on the switching edge two defined angular positions of the bucket to control the screw conveyor for the rotary valve and the bucket itself so that the Cell wheel in the position "cell open at the top" is stopped in the rotary motion, with the charging device is filled until a defined amount of bulk material is in the cell, then the charging device is stopped and the cell wheel is further rotated. The combination of screw conveyor with a rotary valve mainly serves the burn back protection, in order to avoid the burn-back in the storage container for the kiln. In such arrangements of rotary valves, these are usually not arranged concentrically with the screw conveyor, but are installed at the end of the screw conveyor next to this, so that the fuel falls from above into the rotary valve.
    Boiler for lumpy kiln, as e.g. Wood chips or pellets are often operated with negative pressure in the combustion chamber. Such boilers are operated according to the so-called induced draft concept. Characteristic of this is that no combustion air blower is used, but an exhaust fan at the boiler outlet, which ensures the suppression in the entire boiler. This has the advantage of a higher operational safety of the boiler without risk of deflagration. In addition, this can also reduce the need for electrical energy for various drives of the boiler.
    The object of the present invention is to provide a conveyor for a combustion device. In particular, it is a partial object of the invention to provide a conveyor for a combustion device which is operated with negative pressure.
    This object of the invention is achieved in the heater mentioned above in that the rotary valve coaxial with the first screw conveyor and this is then arranged and that connects to the rotary valve another screw conveyor, which is arranged coaxially to the rotary valve.
    By coaxial arrangement of the rotary valve between two augers a division of the entire conveyor line between the Brenngutlager and the combustion chamber is achieved. It is thus possible in a simple manner to adapt the entire conveyor line with respect to the available delivery volume to the expected delivery volume of conveyed by different large screw conveyors can be easily combined. On the other hand, it is also possible to operate within the conveyor line, the individual screw conveyor with different internal pressure, i. that, for example, the first screw conveyor at normal pressure, ie ambient pressure, is operated, while in the further screw conveyor suppression or overpressure may prevail. In addition to the pressure separation between the screw conveyors, however, the rotary valve also fulfills the task of backfire protection, so that therefore no further measures have to be taken with regard to its own back fire protection.
    According to an embodiment of the heating device can be provided that the further screw conveyor has a larger diameter and / or a greater pitch than the first screw conveyor. It can thus be achieved that the required delivery rate can be adjusted within the total conveying distance to the volume to be delivered. As a result, a reduction of the required electrical energy for driving the screw conveyors can be achieved by the reduction of masses to be moved. In addition, by the increase in the available delivery volume over the entire conveyor line a stoppage of the conveyor system can be better avoided by clamped conveyed.
    It is also possible that the rotary valve has a housing, wherein the housing forms a rotor with thereon arranged Zellradflügeln the rotary valve. With this embodiment of the outer rotor, the connection of the rotary valve to the two screw conveyors can be simplified, since it is thus possible that the screw conveyors can be partially installed reaching within the rotary valve.
    A further simplification of the arrangement of the rotary valve within the screw conveyor can be achieved if the further screw conveyor has a worm shaft and the rotary valve is arranged on this worm shaft. In particular, thus the concentration of the rotary valve with the other screw conveyor can be made easier. In addition, the supply of the conveyed material into the rotary valve is thus easier to accomplish by the screw flight of the other screw conveyor can be formed leading up to the rotary valve.
    It is also possible that the first screw conveyor has a first worm shaft and the rotary valve is mounted on at least one slide bearing on the first worm shaft. Although roller bearings are usually better in terms of friction than plain bearings, at least one plain bearing is preferably used for supporting the rotor of the rotary valve, since it shock absorber can be better absorbed. Shock loads can occur, for example, if the conveyed contains oversized particles which, due to their size, tend to jam within the conveying path. In addition, by using at least one sliding bearing, the required installation space volume of the rotary valve can be reduced. Furthermore, an extension of the service life of the storage of the rotary valve can be achieved, in particular because slide bearings are more resistant to contamination.
    According to another embodiment of the heating device can be provided that the further screw shaft of the further screw conveyor is designed tubular, wherein a part of the screw shaft of the first screw conveyor protrudes into the screw shaft of the further screw conveyor. It is thus in the field of rotary valve easily a gain of the worm shaft part on which the rotary valve is located, reachable without complex additional measures must be taken.
    For better discharge of the material to be conveyed from the rotary valve in the other screw conveyor can be provided that at least a portion of the rotor of the rotary valve is formed with at least one screw, which according to a variant to the at least one helix can be formed on the front side of the rotor.
    The rotary valve can have at least one connection for introducing a fluid into the rotary valve. It is thus a simple cleaning of the rotary valve, e.g. with compressed air, achievable, without the rotary valve must be disassembled for this purpose. In particular, it is thus possible to protect by inserting a gaseous fluid, in particular fresh air, the rotary valve with in front of forming condensate or to remove this again from the rotary valve, whereby the setting of fuel or generally conveyed be prevented in the rotary valve can. It can thus be the promotion of the respective material to be improved or maintenance intervals can be extended.
    According to a further embodiment, it can be provided that the rotary valve has two sub-volumes which are pressure-tight against each other. In particular, this embodiment is suitable for heaters that work according to the above-mentioned induced draft concept. It is possible in this way, already within the screw conveyors to create a transition from normal pressure to vacuum or negative pressure to normal pressure (depending on the location of the rotary valve, as will be explained below), so that immediately before the combustion chamber for this no action must be taken. Due to the concentric arrangement of the rotary valve to the two screw conveyors also the required space for the conveyor system to the combustion chamber or away from the combustion chamber can be reduced.
    According to another embodiment of the Fleizeinrichtung can be provided that the rotor of the rotary valve is driven by the first and / or the further screw conveyor. It can thus be carried out structurally smaller the system "rotary valve" because it can be dispensed with a separate drive for the rotor of the rotary valve.
    According to a particular embodiment, it can be provided that the rotor is connected to the worm shaft of the further screw conveyor, whereby on the one hand, the above-mentioned effects can be further improved. On the other hand, this can also be achieved in a simple manner that rotates the rotor of the rotary valve at the same speed of the screw conveyor or.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    Each shows in a simplified, schematic representation:

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals and the same component names, the disclosures contained throughout the description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
    In Fig. 1, a Fleizvorrichtung 1 is shown schematically. Such heaters 1 are commonly used to generate heat in the home or business.
    The heating device 1 has a combustion device 2 (a boiler) with a combustion chamber 3. Furthermore, the heating device 1 comprises a storage container 4 or a storage space for lumpy firing material (conveyed material), such as e.g. Wood chips or pellets. The storage container 4 is connected via a conveyor 5 with the combustion device 2, in particular the combustion chamber 3, so that the fuel can be supplied from the storage container 4 via the conveyor 5 to the combustion chamber 3. For this purpose, a discharge chute 6 or, more generally, a discharge device can be arranged at the end of the conveying device 5, via which the firing material slides into the combustion chamber 3. In order to bring the kiln to the conveyor 5, in the storage container 4, a further conveyor, such as a Bodenrührwerk 7, may be arranged.
    Next, the combustion chamber is connected via a conveyor 5 with an ash container 8. The ash (mostly dust-like material to be conveyed) can be transported via the conveyor 5 from the combustion chamber 3 via an ash collecting space below the combustion chamber 3 into the ash container 8, whereby fully automatic ash removal of the burner 2 can be achieved.
    The combustion device 2 may further comprise at least one heat exchanger 9, through which the flue gases during its passage from the combustion chamber 3 in the fireplace heat can be withdrawn. Since ash can also occur here, it is possible to supply them from the so-called turning chamber below the heat exchanger 9 via the conveyor 5 to the ash container 8. With turning chamber while that chamber below the heat exchanger 9 in the burner 2 is referred to, in which the flue gases are deflected on their way into the chimney.
    Since such embodiments of heating devices 1 with the exception of the conveyor 5 are known from the prior art, reference is made to avoid repetition of the relevant literature.
    It should already be mentioned at this point that the heating device 1 may have a conveying device 5 for feeding the combustible material into the combustion chamber 3 or a conveying device for deashing the combustion chamber 3. However, it is also possible that both the supply of the combustible material to the combustion chamber via a conveyor 5 and the deashing of the combustion chamber 3 via a conveyor 5 takes place. In the event that either the supply of the combustible material into the combustion chamber 3 or the ash removal of the combustion chamber 3 via the conveyor 5, the other conveyor, ie those for the deashing or those for the supply of the combustible material in the combustion chamber 3, the Be formed according to the art. In a preferred embodiment of the heating device 1, however, both conveyors 5, ie those for the feeding of the fuel into the combustion chamber 3 as well as those for deashing the combustion chamber 3 according to one of the embodiments of the conveyor 5 described below are formed.
    It should be mentioned at this point that the conveyor 5 described below can also be part of a larger conveyor, so that, for example, at least one further screw conveyor (intermediate screw) arranged and with the conveyor 5 described below can be functionally connected.
    In Fig. 2, a variant of the conveyor 5 is shown cut in side view. The conveyor 5 has a first screw conveyor 10, a further screw conveyor 11 and a rotary valve 12 or consists of these conveying elements.
    Although not shown, the further screw conveyor 11 is housed, i. that this part of the conveyor 5 is surrounded by a housing, when the conveyor 5 for supplying the fuel to the combustion chamber 3 of the combustor 2 (Fig. 1) is used. But it is also possible that the first screw conveyor 10 is housed at least in a portion of its total length.
    The further screw conveyor 11 has an outlet 13 for the kiln, which opens into the combustion chamber 3 and is arranged in the heating device 2 in the region of the combustion chamber 3.
    If the conveyor 5 is used for ash removal of the combustion chamber 3, the further screw conveyor 11 has an inlet which is arranged below the combustion chamber 2. The inlet can also be designed so that the further screw conveyor 11 is designed to be open, that is, it has no housing or extends only over a partial area of its length.
    The rotary valve 12 is arranged coaxially with the two screw conveyors 10, 11 in the conveyor 5. Furthermore, the rotary valve 12 can be connected directly to the first screw conveyor 10 in a conveying direction 14 and the further screw conveyor 11 can connect directly to the rotary valve 12 in the conveying direction 14.
    The first screw conveyor 10 has a first screw conveyor 15. The further screw conveyor 11 has a screw conveyor 16. The augers 15, 16 may be formed according to the prior art.
    Although it is possible for the first screw conveyor 10 and / or the further screw conveyor 11 to be designed as shaftless screw conveyors, the first screw conveyor 10 preferably has a first screw shaft 17 and the further screw conveyor 11 has a further screw shaft 18 on which the first screw conveyor 15 and the further screw conveyor 16 are arranged and connected to the corresponding shafts.
    The first worm shaft 17 may be formed as a solid shaft or as a Flohlwelle. Likewise, the further worm shaft 18 may be formed as a solid shaft or as a Flohlwelle. In the joint area, the two worm shafts 17, 18 can be arranged adjacent to each other and optionally connected to each other. But it is also possible that the two screw shafts 17, 18 are arranged separately from each other, since the rotary valve 12, the distance between the two screw shafts 17, 18 can bridge.
    According to a preferred embodiment variant, however, it is provided, as shown in FIG. 2, that the first worm shaft 17 is a solid shaft and the further worm shaft 18 is a floating shaft (thus tubular). It is advantageous if the first worm shaft 17 has an outer diameter 19 which corresponds to an inner diameter 20 of the further worm shaft 17 at least approximately, so that the first worm shaft 17 can be inserted with an end portion in the second worm shaft 18. The connection of the two worm shafts 17, 18 can be made non-positively, for example via at least one screw 21, which extends through the two worm shafts 17, 18, with nut or at least one rivet, and / or frictional and / or positive and / or cohesive. This has the advantage that both screw conveyors 10, 11 can be driven by a common, not shown drive device. In addition, this embodiment has the advantage that both worm shafts 17, 18 rotate at the same speed.
    As already stated above, the rotary valve 12 can be arranged in the conveying direction 14 between the two screw conveyors 10, 11. In the preferred embodiment of the Fleizeinrichtung 1 the rotary valve 12 but at least partially disposed on the further screw shaft 18 of the further screw conveyor 11. Preferably, both the first screw shaft 17 of the first screw conveyor 10 and the further screw shaft 18 of the further screw conveyor 11 protrude into the rotary valve 12, wherein particularly preferably the composite of the first screw shaft 17 and the further screw shaft 18 through the rotary valve 12 extends therethrough , as can be seen in FIG. 2. The rotary valve 12 can be arranged on the one hand on the further screw shaft 18 and a portion of the first screw shaft 17 may be arranged overlapping.
    In the embodiment of the heating device 1 in which the rotary valve 12 is at least partially disposed on the further worm shaft 18, it can be provided that the rotary valve 12 is not only arranged on the further worm shaft 18, but that it is also connected to this, so that a rotor 22 of the rotary valve 12 with the other screw shaft 18, and optionally with the associated first screw shaft 17 rotates with. It can thus be provided that the rotor 22 of the rotary valve 12 is driven by the first and / or the further screw conveyor 10, 11. It is thus achieved that the rotor 22 of the rotary valve 12 also rotates at the speed of the worm shaft (s) 18, 17.
    For connection of the rotor 22 of the rotary valve 12, this can have an opening in the axial direction, so that the further worm shaft 18 can extend into the rotary valve 12. The compound itself, i. the connection of the rotor 22 to the further worm shaft 18 can be made non-positively and / or frictionally and / or positively and / or cohesively.
    However, it is alternatively or additionally possible for the rotor 22 to be connected to the first worm shaft 17 of the first worm conveyor 10 in such a way.
    Of course, it is also possible that the rotary valve 12 has its own drive unit, with which the rotor 22 can be driven.
    The rotary valve 12 has, in addition to the rotor 22, a stator 23, as is known per se. According to a further embodiment variant of the heating device 1, this stator can be mounted on the first worm shaft 17 of the first worm conveyor 10, or the reverse configuration is also possible, ie the stator is mounted on the further worm shaft 18 of the further worm conveyor 11 when the rotor 22 of the rotary valve 12 is disposed on the first worm shaft 17 and optionally connected thereto. The following statements are therefore adapted accordingly also valid with respect to this embodiment.
    By the storage is made possible that the first and second worm shaft 17 and 18 can rotate freely without the stator rotates with.
    For storage purposes, at least one roller bearing, for example a roller or roller bearing, can be provided, which is arranged between the first worm shaft 17 (or the further worm shaft 18) and the stator.
    In the preferred embodiment of the heating device 1, the storage of the stator 23 but via at least one sliding bearing. At least one radial sliding bearing, in particular a plain bearing bush 24, and at least one axial sliding bearing, in particular a thrust ring 25, are particularly preferably used. The at least one radial sliding bearing is preferably arranged in an annular groove 26 of the stator 23, wherein the annular groove 26 in the direction of the further worm shaft 18 is preferably open, so that a plain bearing bush can be inserted. The axial sliding bearing is arranged between the stator 23 and the rotor 22 in the region of the contact of the rotor 22 with the stator 23.
    It is also possible to use only a plain bearing, which fulfills both functions by a sliding bearing bush 24 is frontally provided with a sliding coating.
    Preferably, the at least one sliding bearing is a maintenance-free sliding bearing.
    As already mentioned, the rotary valve 12 has the rotor 22 and the stator 23 and consists of the rotor 22 and the stator 23. A variant of the rotor 22 is shown in more detail in FIGS. 3 and 4. In this case, for better illustration in Fig. 4, a housing shell 27 of the rotor 22 is not shown.
    In principle, it is possible that the rotor 22 of the rotary valve is disposed within the stator 23, that is, that the stator 23 surrounds the rotor 22. In the preferred embodiment of the rotary valve 12, however, the rotor 22 is disposed on the outside and forms a housing shell 27 having the housing 28 of the cellular wheel screw 12, which surrounds the stator 23 at least partially.
    The housing 28 has a plurality of cellular wheel blades 29 on an inner surface. The cellular wheel blades 29 extend from this surface toward the central axis of the rotary valve 12. Although the cellular wheel blades may extend radially inward, they preferably deviate from the radial direction and are inclinedly disposed therewith.
    Furthermore, the cellular wheel blades 29 may have a first wing part 30 and at least one further wing part 31. The first Zellradflügelteil 20 is oriented at least approximately in the axial direction. The at least one further cellular wheel blade part 31, which is arranged in the conveying direction 14 in front of the first cellular wheel blade part 30, is, however, inclined towards the axial direction, optionally with a curved surface. It can thus be achieved improved transport of the combustible material in the rotary valve 12.
    With regard to the expression "kiln material", it should again be pointed out that the conveying device 5 can also be used for deashing the fleece device 1. In this case, therefore, this term "kiln" is to be read as "ashes" throughout the description.
    Although the rotary valve 12 preferably has a plurality of cells 32, training with only one cell 32 is also possible.
    As can be seen from FIG. 2, the first conveyor screw 15 of the first screw conveyor 10 protrudes into the rotary valve 12, in particular into the stator 23, for which purpose it has a corresponding opening. Thus, the kiln is conveyed from the first auger 15 to the rotary valve 12.
    The further auger 16 of the further screw conveyor 11, however, can only begin at the output of the rotary valve, for example, when the white tere auger 16 has a larger diameter 33 (Fig. 2), as the output of the rotary valve 12. In this case, it is for the promotion of the combustible advantageous if at least a portion of the rotor 22 of the rotary valve 12 is formed with at least one screw 34. Preferably, a plurality of flights 34 are arranged. The one or more flights 34 may be formed in particular on the front side of the rotor 22, and optionally extend into a portion of the outer surface of the housing shell 27, as shown in Fig. 3.
    In Fig. 5 a preferred embodiment of the stator 23 is shown cut in side view. The stator 23 has an inlet 35, through which the kiln enters the rotary valve 12. Further, it has an outlet 36 through which the kiln leaves the rotary valve 12 again. Between the inlet 35 and the outlet 36, a cross-sectional taper 37 is formed, which has an opening 38 which is so large that only the first worm shaft 17 passes through. In the radial direction below the cross-sectional taper 37, a further opening is formed, through which the firing material passes into the region of the rotor 22, which then takes it by rotation with upward in the region of a third opening 40, through which the kiln finally to the outlet 36 arrives. The stator thus has a first chamber 41 and a subsequent in the conveyor 14 to this second chamber 42, whereby the rotary valve can be divided into two sub-volumes. According to one embodiment of the heating device 1, the two sub-volumes can be pressure-tight against each other, which can be better achieved that the kiln can be promoted in the first screw conveyor 10 under a different pressure than in the other screw conveyor 11. It is thus an improved supply of the combustible material in a combustion chamber 3 (Fig. 1) possible, which is operated with negative pressure, since the further screw conveyor 11 can also be operated with negative pressure in the region of the further screw conveyor 16.
    By dividing the entire conveyor line, which is covered by the conveyor 5, on two partial conveying areas, which are each served by one of the two screw conveyors 10, 11, with the transfer of the Brenngut from the first screw conveyor 10 to the other screw conveyor 11 by means of the rotary valve 12th but it is also possible that the two screw conveyors 10, 11 are designed differently. So it is e.g. possible that the further screw conveyor 11 has a larger diameter 33 than the first screw conveyor 10. Alternatively or additionally, however, is also possible that the two screw conveyors 10, 11 are formed with a different pitch of the screw conveyors 15, 16.
    In the case of the use of the conveyor 5, it is advantageous if that screw conveyor 11 is arranged with the larger pitch and / or the larger diameter closer to the burner 2 and in this opening. In the event that the conveyor 5 is used to discharge the ash from the combustion chamber 3 and the heat exchanger 9 (Fig. 1), as indicated by dashed lines in Fig. 1, it is advantageous if the first screw conveyor 10 with the smaller diameter is arranged below the at least one heat exchanger 9 in the turning chamber, and the further screw conveyor 11 is arranged with the larger diameter in relation to 33 below the grate of the combustion chamber 3 and into the ash container 8, since the ash attack below the grate of the combustion chamber 3 in terms of volume is greater than in the turning chamber. Alternatively or additionally, it is possible for a lower pressure to prevail in the first screw conveyor 10 in the turning chamber than in the further screw conveyor 11 below the combustion chamber 3.
    It may further be provided, as indicated by dashed lines in FIG. 5, that the rotary valve 12 has a connection 43 or a plurality of connections 43 for introducing a fluid, in particular compressed air or ambient air (which is sucked through the negative pressure in the system), into the rotary valve 12, the at least one connection 43 is preferably arranged on the stator 23 and in particular in the region of the inlet 35. About this connection 43 for a fluid flushing line for cleaning the rotary valve 12 can be connected.
    The exemplary embodiments show or describe possible embodiments of the heating device 1, wherein it should be noted at this point that various combinations of the individual embodiments are possible with each other.
    For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the heating device 1, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.
