Description

The present invention relates to a movable unit for receiving, transporting and dispensing previously recorded moist material, wherein the unit comprises a distribution truck with a buffer for the second-wise reception of moist material.

Furthermore, a system for receiving moist material is proposed, wherein the system has a plurality of adjacently arranged receiving fields for receiving moist material and at least one movable unit, with the aid of previously recorded by the aggregate moist material to the individual recording fields transportable and can be applied to the individual receiving fields wherein the unit has a distribution truck with a buffer for receiving the moist material.

Finally, the invention relates to a method for applying moist material in a system for receiving the moist material, wherein the moist material is applied by means of a distribution trolley successively to a plurality of adjacent receiving fields of the system.

In the context of the invention, the moist material may, for example, be sewage sludge, as obtained in the clarification of wastewater in sewage treatment plants, for example in the form of primary sludge, secondary or surplus sludge, activated sludge or return sludge.

Alternatively, the moist material according to the present invention may also be fermentation residues, paper sludge, street sweepers or wood chips.

The moist material must usually from the place of origin, z. As a clarifier, to another location for further processing, for. B. to its drying, to be transported. For this it is known that moist material z. B. with the help of a wheel loader or with the help of conveyor belts from one point to another place to transport. While the first variant is labor-intensive, the second variant is relatively inflexible, since the conveyor belts are usually arranged rigidly.

Object of the present invention is to propose a movable unit for receiving, transporting and dispensing previously recorded moist material, a plant equipped with it and a method for applying moist material in a facility provided for this purpose, each representing a development of the prior art.

The object is achieved by an aggregate, a system and a method having the features of the independent claims.

The unit according to the invention comprises, in addition to the said distribution truck, a transport vehicle which is adapted to receive the distribution vehicle and to be transported by a loading unit, with the aid of which the distribution vehicle can be filled with moist material, to a delivery point remote from the charging device, at which the distribution vehicle is the moist material gives up again.

The distributor car is a device which can be moved or moved along a predetermined roadway, which may be, for example, the distributor roadway described in more detail below in connection with the system according to the invention.

Furthermore, the distribution truck has a buffer in the form of a cavity into which moist material can be introduced via an inlet. The inlet may be an inlet opening of an upwardly closed cavity. It is also conceivable that the buffer is formed like a trough and can be filled from above without the moist material must be introduced through a special opening.

In the interior of the distribution truck preferably has a conveyor, such as a screw conveyor, through which the moist material can be moved within the buffer. This is particularly advantageous if the distribution truck can be filled via an opening with moist material, since the distribution of the moist material can be taken over within the intermediate storage by the conveyor. Also, the conveyor can be arranged below the buffer and ensure during operation that moist material is moved from the buffer in the direction of an outlet of the distribution car.

The distribution truck preferably has an elongated shape, d. H. its length has an amount which corresponds to at least five times, preferably ten times, the amount of its width.

While the distribution trolley serves to accommodate and subsequently dispense the moist material elsewhere, the trolley of the aggregate serves to transport the distribution trolley. The distribution truck can thus be coupled to the trolley, with the help of which transported to another location and there again decoupled from this, d. H. be separated.

Furthermore, it can be provided that the transport cart has a receiving arrangement, wherein the distribution cart, after being received via the receiving arrangement, has no contact with the roadway on which the transport cart is moved. The receiving arrangement preferably comprises a rail arrangement, on which the distribution car can be driven and parked there in order to be transported by the transport vehicle.

It is particularly advantageous if the transport carriage has wheels, by means of which it can be moved along a roadway. It is also advantageous if the distribution car has corresponding wheels. Thus, the distribution car, after it has been decoupled from the trolley, regardless of the trolley along a roadway and can be moved here. The trolley thus serves to move the distribution truck, after it has been filled with moist material, in the immediate vicinity of the point at which the moist material is to be delivered. Once there, the distribution truck is finally decoupled from the trolley and moved independently of the trolley to the respective point at which the moist material is to be discharged from the distribution truck.

It when the axes of rotation of the wheels of the trolley perpendicular to the axes of rotation of the wheels of the distribution car, when the distribution truck is taken up by the transport vehicle is particularly advantageous. The trolley and the distribution car can thus be moved along different lanes, which have an angle of 90 ° to each other. If the unit is now used in a system according to the following description, then the transport vehicle can be moved with the recorded distribution truck along a connecting roadway. If the trolley reaches the area in which the moist material is to be discharged, the distribution trolley is decoupled from the trolley. Subsequently, the distribution truck can be moved along a distribution lane and there drain the existing moisture in the buffer.

The axes of the respective wheels can thus rigid, d. H. not steerable, be formed. It is therefore advantageous if neither the distribution car nor the transport vehicle have a steering. Both carriages can thus be constructed inexpensively and with low maintenance. Due to the mutual arrangement of the axes of rotation of the wheels, it is still possible to move the distribution truck either together with the trolley or alone, so that any existing delivery point can be achieved by the distribution truck.

Furthermore, it is advantageous if the trolley has at least one receiving arrangement which serves to receive the wheels of the distribution trolley when it is received by the trolley. The receiving arrangement may, for example, two receiving surfaces, for. B. in the form of rails, on which the wheels of the distribution car can be moved. Preferably, two corresponding receiving surfaces are provided, on each of which two wheels can be parked. The distribution truck can therefore be moved by means of its wheels on the receiving arrangement of the trolley. After the distribution truck has been moved onto the transport trolley, the distribution trolley can finally be transported piggyback from the transport trolley.

In particular, the receiving surfaces should be located above the wheels of the trolley. This is advantageous if said distributor track has a higher level than the connecting track. The term "level" here is to be understood as the vertical position of the respective roadway.

In addition, fixing means can be provided, via which the wheels can be fixed with respect to the receiving arrangement in order to ensure safe transport of the distributor wagon by the transport carriage. By way of example, the fixing means may be recesses in which the wheels of the distributor car are held. Also conceivable are holding elements, for. B. in the form of retaining clips or jaws over which the wheels of the distribution trolley relative to the receiving arrangement can be fixed.

Likewise, it brings advantages when the trolley and / or the distribution car has a drive by means of which at least one wheel of the trolley or of the distribution trolley is drivable to move the trolley or the distribution truck along a roadway. Preferably, both cars each have a separate drive, for. B. in the form of an electric drive. Also, both vehicles may include an energy storage to provide the respective drives with electrical energy. Both carriages can also have an interface, via which they can be wired or wirelessly connected to a central controller. It is also conceivable that both vehicles have a common control, which is part of the trolley or the distribution car. Individual controls as part of each of the two cars are also possible.

Furthermore, the invention relates to the above-mentioned system for receiving moist material. The facility includes several adjacent mutually arranged receiving fields for receiving moist material and at least one movable unit, preferably an aggregate according to the preceding and / or following description. The recording fields are, for example, flat surfaces which are arranged next to one another.

The areas serve z. As the interim storage or drying of moist material, which is spent by means of the aggregate from a point outside the receiving fields to one or more of the receiving fields.

Moisture taken up by the aggregate can thus be transported with the aid of the aggregate to the individual receiving fields and applied to the individual receiving fields. For this purpose, the unit comprises a distribution trolley with a buffer for receiving the moist material and, in addition, a transport trolley which is designed to receive the distribution trolley and to transport it back and forth along a connecting roadway between the individual receiving fields.

Preferably, the trolley and / or the distribution car on one or more of the features described above or below.

In any case, the system comprises distributor tracks extending between the receiving fields, along which the distributor carriage can be moved in order to apply moist material to the corresponding receiving field after it has been separated from the transport carriage in the region of one of the receiving fields.

Furthermore, it is advantageous if the connection lane extends along the longitudinal sides of a plurality of receiving fields arranged in series and adjacent to one another. Incidentally, the receiving fields can be rectangular. For example, several recording fields in one or more rows may be arranged side by side. The connection lane extends in this case along each of a number of recording fields. If there are several rows, it is also possible for there to be a plurality of connecting tracks and a plurality of units, wherein in each case one unit can be assigned to one connecting track.

It is advantageous if the distributor tracks run along rails of the system, which extend between adjacent receiving fields and along which the distributor carriage can be moved in order to deliver moist material from the buffer onto the receiving field located below the distributor carriage. The rails preferably have a length between 5 m and 50 m and / or run in a straight line. Preferably, the rails have a level corresponding to the level of the receiving structure of the trolley, so that the distribution truck can be moved from the trolley to the rails without having to be raised or lowered.

Preferably, a distributor track comprises two rails running parallel to one another, one rail each being assigned to a pair of wheels of the distributor car.

It is particularly advantageous if in each case one receiving field extends between two rails.

Also, the connection lane may have one or more rails on which run the wheels of the trolley or serve the lateral guidance of the trolley or its wheels.

In general, in connection with the term "rail" it should be noted that this may be a metal rail, which causes a leadership of the wheels. Likewise, as a rail concrete or stone construction, for example in the form of a wall, in particular with a height of a few centimeters up to one meter act, which forms a separation of the individual receiving fields and at the same time a support surface for the wheels.

The connecting road (s) and / or the Verteilerfahrbahn (s) may be formed by flat road surfaces that extend between the individual task areas.

Preferably, the distribution lanes have a higher level than the connection lane (s). In particular, the distribution lanes should have a level which corresponds to the level of the receiving structure of the trolley. The distribution truck can thus be moved by horizontal movement of the trolley on the corresponding distribution lane, without having to be raised or lowered. Incidentally, the distributor tracks and / or the connecting track (s) preferably extend horizontally and in each case in a straight line.

In particular, it brings advantages when at least part of the distributor tracks, preferably all distributor tracks, run parallel to each other and perpendicular to the connecting track (s). By moving the trolley so the unit along the connecting lane (s) can be moved to one of the distribution lanes. Once there, the distribution truck is decoupled from the transport vehicle and moved along one of the distribution lanes, to be able to deliver moist material to the appropriate receiving area there. Preferably, the delivery takes place during the movement of the distributor car, so that the moist material, preferably uniformly, is applied to the respective receiving surface. Meanwhile, the trolley preferably stands still, ie it assumes a waiting position until the distribution trolley has been moved again to the trolley and parked on it. Subsequently, the unit can be moved by moving the trolley to another recording field or loaded at a predetermined location with new moist material.

There are also advantages if the system has a feed unit via which the distribution truck can be fed with moist material via an inlet. The loading unit preferably extends into the area of the connection lane, so that the distribution lorry can be loaded with moist material by means of the feeder unit, after it has been transported by means of the transport carriage on the connecting lane into the area of the loading unit. By way of example, the feed unit may be a hose or pipe having an outlet for moist material which ends in the area of the connection track. Likewise, the loading unit by a moist material storage, z. As a silo, be formed, which in turn is filled by a pipe or hose or with a wheel loader with moist material. The unit can thus be connected to the feed connection without having to leave the connection lane. In particular, the filling of the intermediate storage of the distribution trolley can take place without the distribution trolley having to be separated from the trolley.

In particular, it is advantageous if the plant is designed as a drying plant and preferably as a solar drying plant with a roof covering which is at least partially permeable to sunlight. The moist material is applied in this case by means of one or more aggregates on the individual receiving fields and dried there by heat input to a desired degree of drying.

The plant is thus preferably a drying plant for moist material, in which the individual receiving fields serve as drying fields for moist material. In particular, in this case, the receiving fields are separated in a plan view by one or more connecting lanes and a plurality of perpendicular to the or the connecting lanes extending distribution lanes. The trolley (s) are configured to be moved along each one of a connecting roadway while the one or more distribution trolleys are arranged to be moved along each distribution tramway.

Finally, the invention relates to a method for applying moist material in a system for receiving moist material, in particular a system according to the previous and / or following description, wherein in particular an aggregate according to the previous and / or subsequent description can be used.

The method provides that at least one distribution trolley is filled with moist material and transported by means of a trolley along a connecting lane to one of the receiving fields. Preferably, the recording fields are fields of a drying plant, in particular a solar drying plant.

In the area of the receiving field to which the moist material is to be discharged from the distribution truck, the distribution truck is separated from the transport vehicle. Subsequently, the distribution truck is moved along a distribution lane over said receiving field, during which time and / or subsequently moist material is discharged from the distribution truck or its intermediate storage on the receiving field.

Preferably, the moist material is applied during the process of the distribution trolley on the underlying recording field, so that the moist material is evenly distributed on the recording field. Alternatively, it is also possible to selectively discharge the moist material when the distribution truck is stationary.

Preferably, the spreader comprises an inboard conveyor which operates over a pick-up field during the process of the spreader carriage and which causes moisture within the spreader truck to be moved towards an outlet. Likewise, the conveyor may extend over the length of the distributor car and cause in operation, that above the conveyor existing moist material is moved downwards in the direction of the outlet.

Also, it is extremely advantageous if the distribution truck is subsequently coupled to the transport vehicle and transported with the aid thereof along the connection roadway to a loading unit where it is again filled with moist material. With the help of the trolley, the distribution truck is thus transported between individual recording fields and from time to time also to a loading unit. Preferably, both the trolley and the distribution car move automatically with the help of appropriate drives.

It is advantageous if the distribution trolley is transported successively to the individual receiving fields with the aid of the transport trolley, wherein the distribution trolley is decoupled from the trolley in the region of the individual receiving fields and moved along the distribution tramway associated with the respective receiving field. Here it is advantageous if the distribution car at least temporarily applies moist material to the corresponding receiving field. Finally, the distribution truck is repeatedly filled with moist material in the area of the loading unit and then transported to one of the receiving fields.

Also, it is extremely advantageous if the trolley and / or the distribution car are moved back and forth linearly. Preferably, after uncoupling, the transfer carriage is moved back along one of the distribution lanes in one direction and then in the opposite direction, both directions being perpendicular to the connection lane on which the transport carriage is reciprocated together with the distribution carriage when the unit is moved from one of the receiving fields to another recording field or to the loading unit.

Thus, the method advantageously provides that the aggregate, with the aid of which moist material is transported from a moist material delivery to the receiving fields and drained there, comprises a transport carriage and a distribution truck and is thus formed at least in two parts. The trolley serves to transport the trolley to one of the storage areas or to one of the distribution lane. There, the distribution truck is decoupled from the trolley, d. H. separated. While the trolley remains in place, the trolley is moved along the trolley track and continuously or after reaching a certain position releases moist material to the underlying receiving field. Subsequently, the distribution truck is moved back to the trolley and parked on this. Finally, the distribution truck is moved with the help of the trolley to another recording field or a loading unit to be filled there again with moist material.

In principle, the system comprises a plurality of individual recording fields 11 which can be arranged side by side in a row. Preferably, the recording fields 11 around even surfaces on which the moist material 3 can be applied selectively or evenly distributed.

Preferably, the application of the moist material takes place 3 with the aim of this on the respective recording fields 11 to dry. The recording fields 11 may therefore be part of a floor of a solar drying plant.

To moisturize now 3 on the individual recording fields 11 distribute or selectively drain there, the system comprises at least one intended for this purpose aggregate 14 , The aggregate 14 further comprises a trolley 16 and one with the trolley 16 coupled, preferably on this parkable, distribution car 8th ,

Like that 1 to 3 can be seen, the trolley points 16 several wheels 7 on, over it along a connecting lane 17 moved back and forth and thus the individual recording fields 11 is deliverable. Preferably, the trolley 16 a drive 10 on, so the trolley 16 autonomous or controlled by an external control can be moved. The connecting lane 17 is arranged such that the trolley 16 and thus also the distribution car 8th to the individual recording fields 11 can be transported.

Before the unit 14 but to one of the recording fields 11 procedure, it is initially in the range of a loading unit 1 with moist material 3 filled. For this purpose, it preferably has a in 4 shown cache 15 on, the z. B. via a feed pipe 5 can be filled.

Is the cache 15 adequate with moist material 3 filled, the aggregate becomes 14 by movement of the trolley 16 to one of the recording fields 11 method. There is the distribution car 8th from the trolley 16 separated and on a distribution lane 2 issued. The distributor road 2 can, for example, two rails 4 have, on which the distribution car 8th with the help of own wheels 7 perpendicular to the connecting lane 17 can be moved.

Preferably also has the distribution car 8th a separate drive 10 on (see 4 ), with whose help its wheels 7 or at least one of them can be driven. The distribution truck 8th Thus, it is preferably possible automatically along the individual distributor tracks 2 method.

Once there, the distribution truck arrives 8th from the trolley 16 separated and along the corresponding distribution track 2 emotional. During or after the movement finally the discharge of the moist material takes place 3 to the appropriate recording field 11 , This is in 3 shown. The moist material 3 can evenly on the recording field 11 distributed in this case as delivery point 18 serves. Likewise, the moist material could 3 be delivered selectively in the range of a defined point in the form of a heap, if a uniform distribution is not desired.

Furthermore, the figures show that it is advantageous if the dolly 16 a recording arrangement 9 on which the distribution truck 8th can be turned off. The recording arrangement 9 can depressions for the wheels 7 of the distribution car 8th or a rail system for receiving and guiding the wheels 7 respectively.

In addition, the recording arrangement should 9 and the distribution lanes 2 lying on the same level, so that the distribution car 8th between the distribution lanes 2 and the dolly 16 can be moved back and forth without having to overcome a height difference.

Incidentally, it should be noted that even the trolley 16 a guide, z. B. in the form of one of the plurality of guide rails, may be assigned, so that the trolley 16 on its intended connection lane 17 stays when it is moved.
