Definitions

  • the invention relates to a device for producing combustible pellets from renewable raw materials, in particular from cereals, cereal grains, straw, rapeseed or the like., With a press ring with radially outwardly extending Ausbringkanälen, with a drivable sun gear 'with inside the Press ring rotating planetary gears, which are guided by the sun gear and with a feed device for the raw materials.
  • the object of the invention is to propose a device of the type mentioned, the low-cost safe production of pellets from renewable resources, especially from grain, cereal grains, straw, oilseed rape or the like. allows.
  • the sun gear is arranged in the interior of the pressing ring and the planet gears are rotatably arranged in the sun gear, that the pressing ring has an internal toothing and the planetary gears have an external toothing, which are in engagement with the internal toothing of the pressure ring, and that the Feed device for supplying the raw materials is formed in the annular gap between the press ring and the sun gear.
  • the teeth of the planet gears are formed approximately semicircular and engage positively in the internal toothing of the press ring.
  • the Ausbringkanäle lie in the tooth base between the teeth of the press ring.
  • a plurality of dispensing channels are arranged at a distance from each other in the tooth base of the press ring.
  • the planet gears are mounted on axles whose ends are mounted in both sides of the sun gear connected to the sun gear discs.
  • rolling bearings are provided between the axles and the planetary gears.
  • the bearings are sealed on both sides, preferably by sealing discs.
  • a heating device for the pressing ring is provided on the drive side of the sun gear.
  • the device for supplying the raw materials is preferably arranged on the side opposite the drive side of the sun gear of the sun gear.
  • the device for supplying the raw materials is formed like a meat grinder with a driving screw arranged drivable in a housing.
  • cutting blades are provided at the front end of the conveyor screw adjacent to the press ring.
  • the pitch of the screw conveyor is formed smaller from its rear end to the front end.
  • the groove depth of the screw conveyor is formed smaller from its rear end to its front end.
  • the screw conveyor has individual sections without incline.
  • the inner wall of the housing of the screw conveyor has advantageously extending in the conveying direction grooves.
  • a cutting device is provided with rotating on the circumference of the press ring cutting blades.
  • Fig. 1 exists one; Apparatus for producing combustible pellets from renewable raw materials, in particular from cereals, cereal grains, straw, rapeseed od.
  • a device 2 for supplying the raw materials to the pressing ring a controllable drive 3 for the device 2 for the supply of raw materials a controllable drive 4 for a ring gear associated sun gear, a cutting device 5 with circumferential on the circumference of the press ring 1 cutting blades 6, one of the device for the supply of raw materials associated hopper 7 and metering devices 8 for the raw materials.
  • the raw materials to be formed into pellets are fed via the metering devices 8 and the funnel 7 to the device 2 for supplying the raw materials to the pressing ring 1.
  • the feed rate of the raw materials to the pressing ring 1 can be adjusted.
  • the controllable drive 4 of a sun wheel associated with the press ring 1 the processing speed of the raw materials is set to pellets.
  • the emerging on the outer circumference of the compression ring 1 pellets are separated from the cutting blades 6 of the cutting device 5.
  • the pressing ring 1 has an internal toothing 9.
  • a sun gear 10 is arranged, which is connected via a shaft 11 to the drive 4.
  • the sun gear 10 are four planet wheels 12 ( Fig. 8 ) arranged symmetrically at intervals of 90 ° rotatable.
  • the planet gears 12 have an outer toothing with approximately semicircular teeth 13 (FIG. Fig. 3 and 8th ), which engage positively in the internal toothing 9 of the press ring 1, as in particular the Fig. 3 shows.
  • a heater 20 is arranged with electrically heated heating elements 21 on the press ring 1.
  • the device 2 for supplying the raw materials is arranged on the drive side of the sun gear 10 opposite side of the sun gear.
  • the device 2 for supplying the raw materials is formed like a meat grinder with a conveyor screw 23 arranged in a housing 22.
  • the screw conveyor 23 is via the drive 3 ( Fig. 1 ).
  • the screw conveyor 23 carries at its front end a cutting device 5 ( Fig. 10 ) with cutting blades 6 for crushing larger particles in front of the press ring. 1
  • the housing 23 has in its interior in the conveying direction extending grooves 25th
  • FIG. 10 shows how the particular Fig. 10 shows, increases the slope of the screw conveyor 23 and the groove depth of the screw conveyor from its rear end to the front end with the cutting device 5, so that results in a compression of the raw materials at the front end.
  • the Fig. 10 shows further that the screw conveyor 23 has individual areas without slope, so that the raw materials are transported in a pulse.
