Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Such a device is known for example from CH-PS 466 800.
  • the bulk material here
  • the disadvantage of the known device is that a relatively large height of the steep conveyor must be provided for a certain amount of bulk material or that, because of the steeply falling pile, a favorable use of space is practically impossible. A better use of the area is achieved with a fill that is trapezoidal in cross section, as can be seen, for example, from DE-PS 28 10 842.
  • a horizontal conveyor is provided there, but according to these known proposals, relatively expensive, complex and repair-prone devices are necessary in order to supply air or, if desired, to remove the bulk material.
  • the disadvantage of the device according to the US-PS is, however, that the backfill weighs on the conveyor, which has two disadvantages: on the one hand, the conveyor is exposed to a not inconsiderable load, on the other hand, because the backfill on the The conveyor is in no way guaranteed that the removal will proceed evenly.
  • a problem that arises in connection with several conveyors of waste is the following: When composting waste materials, the same becomes - in general after a previous crushing and / or sifting - poured onto a rotting area in order to rot there under the influence of your own or the added moisture.
  • the moisture will mostly be water, but can also be added in the form of mud, liquid manure, waste water, etc.
  • the waste material In order to accelerate the rotting, the waste material is generally exposed to the air in some form, ie it is loosened up in order to promote natural air access and / or air is forced through suction or bubbles.
  • movable humidification devices in the form of movable nozzles can be moved over the rents. Examples of such arrangements can be found in EP-PS 4 094 or DE-PS 24 51 284. But since the decrease in the dampening medium, e.g. Water, which has to be carried out from a stationary point, gives rise to the problem of movable lines which interfere in the rough operation of a composting plant, are difficult to seal and, moreover, can usually only be designed as hoses which have a very limited life. In addition, in such systems the nozzles must nevertheless be arranged at a certain distance from one another, so that an uneven distribution of the moisture can now again result from this. In principle, it would be conceivable to provide an entire network of such nozzles over the entire rotting area, which could then be kept immobile, but then a relatively complicated valve control is required in order to supply moisture precisely where it is needed.
  • the dampening medium e.g. Water
  • the invention is based on the object of designing a device of the type mentioned at the outset in such a way that, on the one hand, it is possible to make favorable, specific use of space and, on the other hand, nevertheless can be worked with relatively simple, easy to maintain components. If possible, transport should also be possible over long distances, but on the other hand, even transport must be ensured. This object is achieved by the characterizing features of claim 1.
  • the device could also be designed in a similar manner to that shown in US Pat. No. 4,139,640. It is a belt conveyor with drivers. Belt conveyors of this type convey the bulk material on their upper run, which makes a certain conveying speed necessary for the discharge to the next conveyor or to a certain point. In the case of processing waste materials, however, the working speed cannot be freely selected because, among other things, according to the progress of the rotting. It is therefore preferred if the device is designed in accordance with claim 2, because in the case of scraper conveyors, ie which move the bulk material with its lower part, the conveying speed, and in particular in the lower speed range, can be selected within a relatively wide range.
  • the inclined conveyor is now a scraper conveyor or cup scraper, the evacuation is even.
  • a further inclined conveyor section is arranged in the manner characterized in claim 7 ensures that the scraped-off material is conveyed over a desired width.
  • the design as a further inclined conveyor means that this further inclined conveyor can be unloaded by gravity, so that the conveying speed is free, even downwards is selectable. If this additional conveyor were a steep conveyor, only centrifugal discharge, ie with relatively high conveyor speeds, would be possible. However, it is necessary to design this conveyor, which has two inclined conveyor sections, as a bucket conveyor, because only such a design makes it possible to convey as a cup scratcher on the lower run as well as a normal conveyor on the upper run.
  • the invention is based on the object of avoiding movable liquid supplies and nevertheless ensuring a uniform liquid supply to the material to be moistened.
  • This object is achieved by the characterizing features of claim 8.
  • the invention therefore actually starts from the solutions of the first-mentioned group of the associated prior art, but reverses its principle: instead of following the waste material with the liquid, the waste material is conversely transported to the liquid discharge point.
  • This brings an additional advantage because that during loosened rotting material during transport is thus continuously exposed to the ambient air on its way, which is conducive to the breakdown process which is to be started again and prevents nests of rotting good from forming.
  • the removal and transport device in principle, it would be conceivable for the removal and transport device to be formed by similar composting layer machines, which previously also provided the moistening.
  • an arrangement according to feature a) of claim 9 is preferably selected, i.e.
  • a stationary transport track (with vibration transport, endless transport, gravity or the like) is provided, wherein according to feature b) of claim 9, two endless conveyors are preferably provided, between which the stationary irrigation is arranged.
  • an arrangement according to feature c) of claim 9 will be the most expedient, although it would also be conceivable to feed the rotting material, for example, for further comminution, in particular selective comminution, for example in a drum mill, after moistening.
  • the stationary irrigation device could indeed be formed by spray nozzles similar to those in the known compost converting machines which spray their spray jet into the thrown or falling rotting material and thus ensure uniform moistening.
  • training according to claim 10 is expedient.
  • Fig. 1 shows a preferred embodiment in side view, partially in section
  • the bulk material to be rearranged is rotting waste material on a rotting area 1, on which several rents 2 of waste material to be rotted (only one is shown in FIG. 1).
  • the rotting area 1 can be formed in a manner known per se, for example with air supply channels or (not shown) embedded in the ground Tubes for forcing air to pass through the fill of the piles 2, be it through suction or through blowing.
  • all these parts are of a known nature, so that they do not have to be described.
  • the rents are triangular in cross-section, so that the volume is determined by the base area and the height. If, on the other hand, you want to achieve a better specific use of space, you have to switch to a trapezoidal rent 2, as can be seen in FIG. 1.
  • the inclined conveyor 3 is designed as a scratch conveyor due to its conveying direction f, ie scratches 6 acting on its lower run 3a constantly take up material from the inclined surface of the trapezoid of the rent 2, where a horizontal conveyor 7, preferably with its lower run 7a effective scraper conveyor that conveys material along the top of the rent 2 in the direction of an arrow f.

  • inclined conveyors 3 and o horizontal conveyors 7 can in principle be fixed in the relative position shown to one another and can be moved together along the rail or the loading bridge 5 by means of rollers 10. Since the inclined conveyor 3 constantly feeds material upwards and to the horizontal conveyor 7, 5 the necessary positional relationships of the two conveyors 3, 7 do not change.

While a motor 13 may be provided for feeding the rollers 10 along the rail 5, a cable pull 14 could be provided to achieve the travel movement of the inclined conveyor 3 along the rail 11, one end of the cable 14 with the roller 12 and the other End is connected to a winding roller 15 which is driven by a motor 16.

Abstract

Des matières en décomposition dans un tas de compost (802) sont enlevées et déversées à un nouveau par un dispositif d'enlèvement et de transport (804-813). Le dispositif d'enlèvement (804) consiste en un convoyeur à racloirs qui racle avec son côté inférieur et transporte les matières en décomposition. De préférence toutefois, le convoyeur à racloirs peut prendre la forme d'un transporteur incliné qui transporte les matières en décomposition le long d'un côté incliné du tas ancien. Afin d'améliorer le transfert des matières en décomposition raclées au dispositif de transport, un racloir à godets peut servir de convoyeur à racloirs. Le processus de fermentation est considérablement favorisé si l'on humidifie les matières en décomposition à l'aide d'un humidificateur (812) stationnaire agencé sur le trajet de transport.
