Definitions
- the invention relates to a roller press or mill according to the preamble of claim 1.
- 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.
- FIG. 1 shows schematically a roller press according to the invention in cross section through the roller axis.
- Fig. 2 shows the arrangement of FIG. 1 in plan view.
- 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 can usually be displaced with its bearing housings against resilient support.
- the roller gap can be adjusted 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 Drs ⁇ hacht 6, which extends with its lower end in the nip 8.
- the filling shaft is shown here with a twofold conveying of the material by means of a press screw 10.
- the material to be pressed is introduced into the filling shaft 6 via a lateral feed 12.
- a plurality of filling screws are arranged next to one another in the axial direction of the rollers, the screws rotating in respective housing sections 14, which each form the lower end of the filling shaft 6.
- the upper part .of the feeding chute 6 can • be common for all adjacent hoppers, which one or more may be provided to chanchte 12th
- 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, 22 of the chambers 16, 18 is through the walls of the lower region of the filling chamber which extend essentially axially parallel or at a plurality of filling screws of the filling shafts.
- This wall 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.
- the walls 20, 22 delimit with 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 can be adjusted, which are shown schematically in the drawing and are arranged here on the outside of the filling shaft wall in a height-adjustable manner.
- 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 roll nip.
- the chambers which are closed by cover walls 32, 34, have air outlets to which dust separators are preferably connected.
- These dust separators can be mechanical dust separators, 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, via which the connection to centrifugal filters 38 or the like is established, to which fans 40 can be connected upstream or downstream.
- filters with a filter medium for example filter cloths or the like, can also be provided, as shown in the drawing on the left.
- 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 that is conveyed into the roller gap by the material to be pressed that is to say is contained in the material that comes from the filling shaft into the roller gap at the lower end of the filling screw, should as far as possible when the material is compressed by the rollers after the the feed angle ⁇ 0 of the roller press, which is essentially dependent on the roller diameter, can be expelled from the material. According to the invention, it can escape laterally in a short way and passes through the spaces 28, 30 into the chambers 16 and 18. Pressed material entrained by this air can and will also pass into the chambers.
- 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 to the filling chamber, by means of which the supply is reduced briefly, so that the material to be pressed located in the chambers 16, 18 is drawn off from the rollers. The material to be pressed is conveyed out of these chambers, as during normal operation, by gravity and by the normally profiled surfaces of the rollers.
