Definitions

  • the invention relates to a pelletizing machine in which press rolls roll on a flat, perforated die.
  • Pelleting machines are used to compress and extrude various types of material under the pressure of rolls, the strands being broken or cut into pellets.
  • the material is partially compacted before it is pressed into the through holes and in many cases also involves crushing and mixing the components. Crushing is particularly necessary for waste that e.g. B. contain paper, textiles, plastics, straw and other parts of plants or consist of such.
  • the press rollers have already been provided with blind holes or with transverse grooves, it could happen with material with a coarse structure or with great moisture that the material was not drawn into the press nip between the press roller and die or the press rollers, which are usually freely rotatably mounted on the pan head, were compacted Material layer slid away.
  • the invention has for its object to form press rolls and die so that the drawing of the material into the press nip and the crushing between press rolls and die and the passage of the material through the die are improved.
  • the surfaces of the press rolls and die are provided with teeth.
  • the teeth on the press rollers are designed so that they grip the supplied material and preferably between the teeth of the die and in any case in press the through holes between the teeth of the die.
  • the teeth also prevent the formation of a densified layer of material on the die above its through holes. Since the die and press rollers engage the teeth at least through the material enclosed between them, the press rollers are inevitably rotated when the pan head is driven with a fixed die or the die is rotated with a fixed pan head.
  • the teeth are pins in at least part of the surface, but the teeth of the press rollers press on the upper side of the die in such a way that they get as far as possible through the entry openings of the through holes.
  • the through holes start from the essentially horizontal upper side of the die and run perpendicularly through it.
  • the entire annular top of the die is provided with through holes between the teeth, the shape and size of which depends on the material to be machined.
  • a vertical axis leads through the center of the die to the pan head.
  • tapered press rollers are used, which are freely rotatable. They are mounted on inclined axes in the pan head, which is driven by a vertical shaft.
  • the die and press rollers are provided with a toothing as in the case of angular drives or bevel gears, the teeth of the press rollers pressing the material between the teeth of the die and into the through holes arranged there, and at the same time tearing and tearing fibrous or flat material when pressed between the teeth rub the tooth flanks and on the base of the matrix.
  • the teeth do not need to run the entire length of the line of contact between the press roller and the die. Smooth surfaces of the roll and the die can also lie between them or next to them.
  • the die in particular, is subject to high wear, it is provided that the die be made in two parts and that the upper part, which is provided with the teeth and the entry openings of the through holes, be easily connected to the lower part.
  • This also makes it possible to provide the lower part with special heating and / or cooling devices in order to influence the temperature of the material and to line the through holes in the lower part with ceramic bushings or bushings made of a special material to prevent the pellet strands from sliding in the Improve holes especially with aggressive media.
  • a drive for a vertical shaft is accommodated in a gear housing 1. These parts are not shown.
  • the vertical shaft rotates the pan head 2, on which 3 conical press rollers 4 are arranged on inclined axes, which are pressed by the pan head 2 against the flat die 5, which is firmly supported on the gear housing 1.
  • a pressure device 8 for the pan head 2 sits on the vertical shaft 7.
  • the press rollers 4 When the Köllerköpfs 2 rotate, the press rollers 4, whose teeth also grip material with a coarse structure, roll on the die 5.
  • the space in which the press rollers 4 work is surrounded by a funnel 6 in which the material to be processed is poured in from above.
  • two press rolls 4 In the pelletizing machine shown, two press rolls 4 are shown. However, three or four press rolls can also be used.
  • a pelletizing machine of the type shown with four press rolls can be designed for a large material throughput and can be used for pelletizing straw, for example.
  • both the die and the press rollers are provided with toothings which engage in one another, as shown in FIG. 2.
  • the die 5 is composed of an upper part 51 and a lower part 52, which are secured against one another by pins 53 or in a similar manner.
  • the teeth 41 on the press roller 4 engage between the teeth 54 on the upper part 51.
  • the inlet openings of the through holes 56, 57 are arranged between the teeth 54.
  • the through holes 57 are surrounded by ceramic bushings 58 in the region of the lower part 52.
  • the lower part 52 also contains channels 59 through which a heating or cooling medium can circulate.
  • the material falling on the press roller 4 or the die 5 is taken along by the teeth and compressed between teeth 41, 54. It is stretched and broken and rubbed between the tooth flanks, which destroys coarse structures.
  • the reduction in the free space between two flanks of the teeth 54 by the penetration of a tooth 41 creates a high pressure in the material, which is thereby pressed into the inlet opening 55 and further into the through hole 56, 57, where the pellet is formed and as a result of the friction is further solidified on the perforated wall.
  • the pressure applied during processing and the friction of the material on the surfaces of the die can lead to a strong increase. cause warming. It can therefore be expedient to protect the die 5 from overheating by means of a coolant in the channels 59.
  • the introduction of a heating medium into the channels 59 can be expedient in order to remove material that is in the passages 56, 57 when the device is switched off. solidifies or becomes very hard to soften before starting the machine again.
  • Ceramic bushings 58 are advantageous if the material to be machined contains aggressive constituents which attack the die, which is usually made of steel, and would produce a very rough surface of the through holes 57 at least after some time.
  • the channels 59 and the bushes 58 can be dispensed with, and the teeth and the size of the passages 56, 57 have to be adapted to the respective use.
  • the teeth prevent the material from jamming in front of the press rolls and improve the size reduction of the material.
  • the teeth 61 of the press roller 4 are widened to approximately twice the pitch.
  • a wide surface 63 corresponding to the tip circle of the teeth 61 can roll over a plurality of through holes 56 or over holes with a very large diameter and press the material into them.
  • the teeth 62 of the die 5 can have a width or pitch as in FIG. 2.
  • a large number of entry openings for the through holes into which the pre-comminuted and, if appropriate, previously ground and mixed material is pressed through the peripheral surface parts 63 can still be accommodated in the flat top side 64 of the die 5.
  • the design of the teeth and the holes is to be selected according to the material being treated, although conical press rolls according to FIG. 1 are also preferred for designs according to this example.
  • conical pressure rollers with a toothing of rollers and die as in FIG. 2 were used.
  • the outside diameter of the die was approx. 760 mm, the height of the teeth approx. 10 mm.
  • the die was tempered to prevent the material from melting and overheating.
  • dies with diameters of approximately 300 to 1600 mm with correspondingly large press rolls can be used, teeth with a particularly large height being usable.
