Definitions

  • the present invention relates to both a method and a device for simultaneously producing a plurality of strands of a moldable material by means of a press, which consists of a plate-shaped die provided with nozzles in the form of through holes and a rotating, with radially arranged rollers pressed onto them provided gyroscope exists.
  • Such presses are already used for the granulation of certain materials, eg. B. for granulating wood waste, plastics and animal feed.
  • the material to be granulated must be dried in known machines of this type in an upstream system and freed from foreign bodies. This represents an additional mechanical, spatial and operational complexity.
  • the invention consists in heating the die to a temperature above the boiling temperature of the moisture contained in the deformable material, thereby drying the material pressed by the die hole-shaped dies.
  • the drying process is carried out according to the invention in a press for the simultaneous production of several strands of a moldable material.
  • This press consists of a plate-shaped die interspersed by hole-shaped nozzles and a spinning top pressed with them and rotating with radially arranged rollers.
  • a press according to the invention is characterized in that the die consists of two closely and sealingly abutting plates, of which in at least one plate in the surface facing the other plate, a channel for a heating of the coolant is formed, with which the die is heated so high that the now gaseous moisture escapes into the environment through the holes in the die and lying behind the holes channels.
  • nozzles in the matrix have, on their side facing the rollers, a cylindrical section which continues in a conically narrowing section.
  • the material is freed from the gaseous moisture contained in it before it exits the nozzles in the die.
  • the hole-shaped nozzles in the lower plate of the die on their sides facing away from the rollers on a conical end portion.
  • the invention further provides that upon the appearance of foreign bodies on the die or clogging of some nozzles by foreign bodies, the drive of the press automatically shuts off.
  • the rotating, provided with radially arranged rollers gyro is slidably mounted on its drive shaft and that in its displacement a switch off the rotation of the gyro serving switch is arranged.
  • the switch can be automatically operated in case of failure and then carried out the necessary cleaning. This is only occasionally considered and represents only a minimal effort compared to a general pretreatment of the entire material to liberate foreign bodies.
  • the press consists in this embodiment of a machine housing 1, in which a die 2 is installed approximately centrally fixed. Above this there is a gyro 3, which carries a roller 5 on three radially arranged arms 4. Each roller 5 runs on the surface of the die 2.
  • a drive shaft 6 for the gyroscope 3 is driven by a motor 7.
  • the drive shaft 6 is divided in its course, wherein a connector 8 ensures a rotationally fixed displacement in the longitudinal direction of the two shaft parts under spring pressure or pneumatic pressure.
  • the lower shaft part is mounted in a bearing 9, the upper shaft part in the engine. 7
  • the die 2 divides the machine housing 1 into a space 10 above the die 2, into which the material to be processed is poured in via feed tubes 11, and a space 12 below the die 2 into which the strands formed in dies 13 of the die 2 fall. after being formed in the nozzles 13.
  • the die 2 consists of two closely spaced plates 14, 15 which have channels 16 for receiving heating elements on the mutually facing sides.
  • the nozzles 13 in the plates 14, 15 of the die 2 are shaped in a special way.
  • the nozzles 13 In the plate 14 on which the rollers 5 run, the nozzles 13 have a cylindrical shape. These are aligned with the nozzles 13 in the plate 15, which adjacent to the plate 14, first a slightly narrowing conical section 17, then a cylindrical section 18 and at the end again have a slightly flared conical end portion 19.
  • This form or design is based on the idea that the mass rolled into the nozzles 13 of the plate 14 of the die 2 is first dried by the high temperature of the die 2. The dried mass shrinks due to the loss of moisture, therefore, it is compressed by the conical portion 17 in the plate 15 to be dried and molded thereon in the cylindrical portion 18. In the conical end portion 19 of the dry strand leaves the nozzle 13 in the plate 15. Thus, a usual predrying can be spared.
  • the particular advantage of the invention lies in the simultaneous removal of moisture from the moldable material processed in the press and their compression in the individual nozzles 13.
