Definitions

  • the invention relates to a hopper for waste incineration plants.
  • a device for equalizing the supply of garbage to an incinerator is already known (US Pat. No. 3,891,105), in which clumps of garbage, particularly when they are in sacks, are torn apart by rake-like tools, so that the garbage is evenly distributed Form can be fed by a conveyor belt of the feed chute.
  • the object of the invention is to achieve a uniform task of the fuel with a low expenditure of energy.
  • a cover is provided over the collecting area or at the inlet of the feed hopper, which cover consists of support bodies for receiving the fuel, which are arranged at a distance from each other and that at least some of the supporting bodies are forcibly movable.
  • a cover consisting of support bodies, which are spaced apart from one another, creates a type of classifying device through which the smaller portions of the fuel fall, the spacings being chosen such that the fuel parts falling through do not cause any difficulties in conveying them into the Combustion chamber and also no irregularities in the combustion. Due to the forced mobility of individual or all supporting bodies, the fuel or waste is also set in motion, causing loosening of matted or tangled fuel parts. In addition, a shifting of the garbage lying on the cover is forcibly achieved, so that in the course of this shifting smaller fuel or. Waste parts that are prevented from falling through by larger fuel parts lying underneath can be separated out, ie the smaller parts reach the cover through the layering so that they can fall through between the supporting bodies.
  • the invention therefore generally relates to a device which prevents the penetration of caked or connected fuel parts which would lead to non-uniform burnout, and by means of a constant shifting and rearrangement causes a separation of connected fuel parts and a sorting out of large fuel parts which result from this Device must be removed if they do not disintegrate by multiple repositioning.
  • One of these possible configurations of the cover is that it is designed in the manner of a grate.
  • the distances between the supporting bodies can be designed to be uniform or non-uniform and adjustable.
  • the cover In order to set the fuel in motion and thus a constant shifting and loosening reach, the cover can be moved overall ie in the manner of a shaking grate.
  • the support bodies can be rotatably mounted about their longitudinal axis or can be guided in their longitudinal and / or transverse direction on a closed path loop or can carry out mixed forms of these movements.
  • the choice of movement type depends on the fuel to be processed.
  • the type of fuel also influences the design of the support body.
  • the support body can be used as rollers or other rod-shaped body, for. B. in the form of angle profiles, U, T or box profiles.
  • the support bodies can be formed uniformly or non-uniformly in their surface profile or in their thickness dimension, that is to say the beam-shaped or roller-shaped support bodies can be cylindrical, truncated cone-shaped or with dimensions that change continuously in the longitudinal direction, so that each individual moving support body is longitudinal Different acceleration forces are exerted on the fuel at each location along its longitudinal extent. As a result, shifts are also achieved transversely to the main direction of movement of the fuel.
  • cylindrical support bodies are mentioned, each support body along its length seen has different diameters, as a result of which the fuel which is in contact with roller sections having a larger diameter is accelerated more rapidly than that fuel which is in contact with locations on the roller-shaped body which are smaller in diameter.
  • force components are generated at an angle to the direction of movement that result from the fact that the roller parts with a larger diameter are connected to the roller parts with a smaller diameter by inclined surfaces.
  • the fuel is essentially moved in a preferred direction and also shifted within this direction of movement.
  • compositions of the fuel may also make it necessary that in a further embodiment of the invention the carrying bodies are provided with projections, lugs, tear or cutting tools, drivers or the like. Through these parts protruding over the surface of the support body, better separation of tangled or matted fuel parts is achieved, but no comminution of unusually large fuel parts or foreign bodies is intended. These parts are separated out and, for example, fed to a bulky goods bunker.
  • the supporting bodies can be designed as screws, whereby they can have uniform or non-uniform pitches. These different pitches can be formed on one and the same screw as well as on different screws, which largely depends on the nature of the fuel. In order to improve the process of pulling apart mutually matted fuel parts, the supporting bodies can not only be movable or rotated in the same direction but also in opposite directions.
  • the support body can be driven individually, in groups or together.
  • the drive of the support body can also be designed such that the direction of movement of individual rollers or screws automatically reverses for a short time when a maximum permissible drive torque is exceeded.
  • the cover can either be inclined horizontally or at an angle to the horizontal, this inclination angle being advantageously adjustable.
  • FIG. 1 shows a section through a feed hopper with a device according to the invention for supplying fuel
  • Fig. 2 is a top view of a hopper with another embodiment of an invent device according to the invention for supplying fuel;
  • FIG. 3 shows a view of an individual support body from the device according to the invention
  • FIG. 4 shows a further embodiment of a support body shown individually

  • FIG. 8 shows a representation similar to FIG. 2 of a device according to the invention arranged on a loading hopper, in which the individual supporting bodies are designed as screws.
  • a feed hopper generally designated 1
  • a conveyor chute 2 which leads to a feed table, not shown in the drawing, from which the fuel is fed into the combustion chamber by means of a loading piston.
  • a cover generally designated 4, which in the exemplary embodiment shown is constructed in the manner of a roller grate.
  • This cover comprises a plurality of rotatably mounted support bodies 5 which are formed as rollers and which have a spacing or space 6 between them, through which correspondingly small parts of the fuel placed on the cover 4 fall, so that they fall onto the collecting area 3, which acts as an inclined chute is formed, fall. From here the fuel slides into the chute.
  • the individual cylindrical support bodies 2 are driven, whereby they can have a common drive or a drive assigned to each support body 5.
  • the roller-shaped support body is driven in such a way that the applied fuel is moved in the direction of arrow 7, individual movements of fuel parts extending transversely to it being deliberately forced within this main direction of movement, in order to achieve a shifting.
  • the given up on the cover 4 fuel or garbage is shifted in its movement in the direction of arrow 7 so that it releases the smaller fuel parts, which are blocked by larger ones, which then get into the spaces 6 between the individual cylindrical support bodies 5 and from there fall into the hopper.

  • This shaking movement can be provided in addition to the rotary movement of the support body 11 or as the only type of movement without rotary movement of the support body 11.
  • a support body 15 which consists of individual frustoconical sections, each abutting with their smaller or larger end faces 16 and 17.
  • the fuel parts are accelerated more strongly at the same number of revolutions of the support body than in the area of the smaller diameters.
  • FIG. 4 shows a support body 18 which corresponds in its basic structure to the support body 15 according to FIG. 3.
  • the support body On the circumference of the truncated cone-shaped sections, the support body has strip-shaped projections 19 which ensure that the fuel parts are better carried along when the support body 19 is driven in rotation.
  • support bodies 20, 22, 24 are shown, which correspond in their basic structure to that of the rollers according to FIG. 1.
  • the support body 20 is equipped with rod-shaped drivers 21 which are arranged parallel to one another and distributed over the circumference of the support body on a helical line.
  • the support body 22 according to FIG. 6 is provided with strip-shaped projections 23, while the support body 24 according to FIG. 7, viewed in cross section, is composed of four spiral segments, so that projections 25 are formed at the respective joints.
  • a cover, generally designated 26 for a hopper 1 is provided, which is constructed from a plurality of screws 27, which are mounted in bearings 28 at their two ends.
  • the ends of the screws engage in a gear housing 29 and are connected via appropriate gear trains to a drive motor 30 which serves as a common drive for all screws.
