Definitions

  • the invention relates to a pressing device for dehumidifying metal chips or abrasive slurry according to the preamble of independent claim 1.
  • Pressing equipment is used to compress mud waste or other material. These devices usually consist of a container from which this material is fed to a compression chamber. In this press chamber acts a pressure generator that compresses the material. If a dehumidification of the material is required, the liquid is simultaneously derived from the material within the pressing chamber by appropriate measures.
  • This device consists of a press screw, which is arranged within a screw shell.
  • the material to be pressed is fed via an entry port of the press screw, whereby the residual moisture in the area of the processing tools evaporates as a result of the amount of heat generated during processing and escapes as a vapor flow through the screw shell.
  • the device has an expansion space through which the escaping vapor flow is passed. The expansion space is part of the shell shell.
  • a disadvantage of this device is the fact that due to the screw compressor principle only a relatively small compression of the supplied material is generated.
  • the invention has for its object to provide a pressing device, in particular for dehumidifying metal chips or Schleifischlamm, which works efficiently and achieves a high press performance at the same time high degree of dryness.
  • the main advantage of the invention is that a conically shaped receiving space is provided for the compact, d. H. in these, the material is conveyed with the plunger.
  • This conically shaped receiving space is variable in terms of volume, d. H. at least one wall of this receiving space is arranged openable. If the back pressure on the plunger rises above a certain level due to the material to be compressed, this receiving space opens to reduce this back pressure. Thus, a balance between the pressure of the plunger and the counter pressure takes place. At the same time, the opening of the receiving space causes the compact to exit, for example into a subsequent collecting container.
  • the plunger and the receiving space are rectangular or have a polygonal shape.
  • the plunger and the conical shaped receiving space are cylindrical.
  • a further pressing piston can be arranged, which first compresses the material fed in the pressing space in a direction arranged at 90 degrees to the pressing piston.
  • an opening for the discharge of liquid from the pressing space is provided.
  • the liquid can subsequently be discharged via openings in the baling chamber or baling chamber via openings, slots or the like.
  • the plunger are hydraulically actuated. This has the advantage that via the hydraulic pressure of the first plunger a control for opening the wall of the conically shaped receiving space is possible.
  • this consists of two concentric half shells, one of the half shells is pivotally movable to the further half-shell. This ensures that the recording room can open.
  • the conveyor is a screw conveyor and passes from this to be dehumidified material in the press room, initially two perpendicular pressing piston press the material and simultaneously move in front of the first plunger.
  • the receiving space formed by the two plungers corresponds to the diameter of the first plunger. After this pre-compression, the material moves through the first plunger in the direction of the conically shaped receiving space.
  • the perspective view of a pressing device 10 shows a container 11, in which the material to be dehumidified 12 is located.
  • a screw conveyor 13 is arranged, which is moved by a drive 14.
  • the container has an opening 16 in the discharge area 15.
  • a chamber is provided as a pressing space 17.
  • the plunger 18, 19 and 20 act.
  • Each plunger is actuated by a hydraulic unit.
  • a dehumidifying chamber 21 which consists of a hollow cylinder, said hollow cylinder has slots 21a through which liquid can be discharged (see also Fig. 2a). Downstream of this dehumidifying space 21 is a conical receiving space 22. Conical in this case means that the diameter of the receiving space 22 decreases from the dehumidifying space 21 to the opposite outlet. At the outlet, a guide channel 23 is provided. Below the dehumidifying space 21 is a drip pan 24 for receiving liquid.
  • the dehumidifying and pressing of the material takes place according to the following scheme: First, the material 12 contained in the container 11 is conveyed by the conveyor screw 13 into the pressing space 17. After a certain amount is in the pressing chamber 17, the plunger 18, subsequently the plunger 19 and then the plunger 20 is actuated in the direction of arrow. As a result, the material is compressed and formed into a cylindrical strand of material due to the plunger shapes.
  • the shaping takes place on the one hand by the flat front surface of the plunger 18, by the semicircular curved front surface of the plunger 19 and by the rigid, the plunger 19 opposite wall, which is also semi-circular shaped (not shown) and part of the pressing chamber 17 forms.
  • the plunger 20 further compresses the thus formed material and pushes it through the dehumidifying space 21 in the direction of the receiving space 22 therethrough.
  • FIG. 2 also shows in a perspective view the pressing device according to FIG. 1, however, in the pressing mode. Identical parts are provided with the same reference numerals. This means that both the plunger 18 and the plunger 19 are in the end position.
  • the pressing piston 20 moves in the direction of the dehumidifying space 21 and thus pushes the material into the conically shaped receiving space 22.
  • the compacted and dehumidified material 25 emerges from the receiving space 22, is guided via the guide channel 23 to a receiving box 26 where it is collected and can be disposed of.
  • the principle of the receiving space 22 is explained in more detail in Figures 3, 4 and 5.
  • FIG. 3 shows a half shell 27 as one half of the conically shaped receiving space 22.
  • the inlet diameter D1 corresponds to the diameter of the pressing piston 20.
  • the outlet diameter D2 is slightly smaller. The reduction between inlet diameter and outlet diameter is about 5 - 10 mm. This means that the material, if it is moved by the plunger 20 in the conically shaped receiving space undergoes a further compression.
  • FIG. 4 shows the material 12 in the conically shaped receiving space 22, which, as already mentioned, consists of two half shells, half shell 27 and half shell 28.
  • the two half-shells in the region of the contact region 29 are positively against one another. Since the material in the receiving space 22 is subjected to further compression, the pressure of the pressing piston 20 must forcibly increase. So that the pressure which is ultimately generated by the hydraulic pressure of the plunger, does not rise above a certain pressure limit, one of the two half-shells can move laterally away, in this example, the half-shell 27.
  • This half-shell is either spring-loaded on the half-shell 28 in the contact area 29 or is supported via another hydraulic cylinder (not shown).
