Definitions

  • the invention relates to a roller press or mill according to the preamble of claim 1.
  • a chamber is arranged vertically above the roller gap in the filling shaft, which projects with its lower end, which is designed to be permeable to air, into the roller gap and which passes through the end walls of the feed shaft through is connected to air outlet lines.
  • air outlet lines Such within the hopper to orderly ventilation devices have the disadvantage that they hinder the flow of material.
  • the very small air inlet openings of the order of 1/10 mm and smaller required at the lower end of the chamber easily lead to blockages of the openings, which render the device ineffective.
  • a roller mill is also known (DE-A-17 57 093, B1), in which the material to be shredded is fed in a steady stream, which is in a chute that ends at a distance above the roller gap up to approximately the circumferential speed the rollers accelerated. Air entrained here should escape above the rollers and be returned to the chute through a duct provided with blinds at the top to prevent the material in the chute from being braked by the air resistance. Air brought in with the crop stream is extracted through openings above the nip to prevent dusting.
  • the object of the invention is to design a roller press of the generic type in such a way that reliable ventilation is achieved without problems due to clogging of the paths through which the air can escape.
  • the solution according to Invention entrain the pressed material escaping through the open passages into the chambers. This can settle in the chambers. Only the residual dust needs to be separated from the air to be removed from the chambers.
  • rollers 2, 4 lying horizontally next to one another are shown of the roll press.
  • These rollers are provided with their roller journals 2 ', 2' 'or 4', 4 '' with bearings with which they are mounted in bearing housings which are arranged in the press frame, not shown, between an upper and a lower frame part.
  • One of the rollers is usually displaceable with its bearing housings against resilient support.
  • the roller gap 8 is adjustable in a known manner in such roller presses, which are also used as roller mills.
  • the feed angle ⁇ 0 depends on the roller diameter.
  • the roller press is provided with a filling shaft 6, which extends into the nip 8 with its lower end.
  • the filling shaft is shown here with a forced conveyance of the goods by means of a filling screw 10.
  • the prepgut is introduced into the filling shaft 6 via a lateral feed 12.
  • a plurality of filling screws 10 are arranged next to one another in the axial direction of the rollers 2, 4, the screws rotating in respective housing sections 14, which each form the lower end of the filling shaft 6.
  • the upper part of the filling shaft 6 can be common to all filling shafts lying next to one another, it being possible for one or more feed shafts 12 to be provided.
  • the filling shaft 6 can also be designed in a known manner as a filling shaft of a gravity allocation, the material then being fed vertically into this filling shaft from above.
  • 6 chambers 16, 18 are provided on both sides of the filling shaft. These chambers extend essentially axially parallel over the width of the pressing surfaces of the rollers 2, 4.
  • the lower region 20, of the chambers 16, 18 is delimited by the walls 22, 24 of the lower region of the filling shaft 6 which extend essentially axially parallel.
  • This wall 22 or 24 can be a straight wall, but it can also be corrugated in accordance with the outer contour of the lower region of the screw housing forming the lower end of the filling shaft 6.
  • the walls 22, 24 delimit at their lower end passages 28, 30 extending essentially over the width of the pressing surfaces of the rolls between themselves and the outer circumference of the rolls 2, 4.
  • the height of the passages can be adjusted by height-adjustable slides 21, 23 , which are shown schematically in the drawing and here are arranged on the outside of the filling shaft wall 22 or 24 adjustable in height.
  • the chambers 16, 18 are closed at their axial ends. This closure can be sealed at least in the lower area, for example, by the usual end wall sealing plates for the nip.
  • the chambers which are closed by cover walls 32, 34, have air outlets to which dust separators 35, 38 are preferably closed.
  • These dust separators can be mechanical dust separators 38, for example those with which the dust is separated by centrifugal force, for example cyclone filters or Vortex chamber filter, as shown in the drawing on the right.
  • air lines 36 are connected to the chambers 16, 18, via which the connection to centrifugal filters 38 or the like is established, to which fans 40 can be connected upstream or downstream.
  • filters 35 with a filter medium for example filter cloths or the like, can also be provided, as shown on the left in the drawing.
  • Filters 35 with a filter medium are each connected to openings in the covers 34. A plurality of these can be provided distributed over the length of the chambers, as shown in FIG. 2.
  • the chambers 16, 18 described above operate as follows.
  • Air which is conveyed from the material to be pressed into the nip 8, that is to say, for example, is contained in the material to be pressed, which at the lower end of the filling screw 10 passes from the filling shaft 6 into the nip 8, should, as far as possible, compress the material by the roller after reaching the feed angle ⁇ 0 of the roller press, which is essentially dependent on the roll diameter, are driven out of the pressed material. It can escape laterally over a short distance and passes through the passages 28, 30 into the chambers 16 and 18. Pressed material entrained by this air can also pass into the chambers 16, 18.
  • Pressed material that has entered the chambers 16, 18 can be drawn back into the nip by the rolls 2, 4, where it is then compressed in the nip with the remaining pressed material. It should be noted that the passage of pressed material into the chambers 16, 18 is counteracted in each case by the roller surfaces rotating counter to the entry into the chamber via the passages 28, so that excessive escape of pressed material into the chambers 16, 18 can be prevented.
  • the chambers can be provided with level sensors, not shown in the drawing. These filling level sensors can then be used to regulate the supply of material into the filling shaft 6, by means of which the supply is briefly reduced, so that the material to be pressed located in the chambers 16, 18 is drawn off from the rollers 2, 4.
  • the conveying of the pressed material out of these combs 16, 18 takes place here, as also during normal operation, by gravity and by the normally profiled surfaces of the rollers.
