Definitions

  • the invention relates to a device for dehumidifying material after Preamble of the main claim.
  • filter presses in the form of plate filter presses are known.
  • the material to be dehumidified is placed between filter discs and under high pressure removes the moisture. This is a batch process very complex.
  • the dehumidified must be used after each operating cycle Removed material, cleaned the facility and added new material.
  • US Pat. No. 4,384,955 discloses a device for dehumidifying material, especially known metal shavings. It consists of a housing with a Feed opening and a discharge opening. In the housing is a helical one Press body arranged. A disadvantage of this device is the fact that compression of the material for discharge is not provided. This means, that the metal chips are partially dried, but the drying rate is relatively small. The system thus has the disadvantage that the chips removed u. U. another drying process must be fed.
  • the invention has for its object a device for dehumidifying To create material that is simple and a continuous way of working enables.
  • the main advantage of the invention is that a compact system is created that works continuously, especially when dehumidifying of metal chips both an oil and an emulsion separation or a Water separation is possible.
  • the invention works on the principle of an extruder and is able to dehumidify very large amounts of material in a short time.
  • the helical one Press body shows a variable slope. The slope expediently increases the spiral towards the discharge opening. With this measure, too achieve higher compaction of the material.
  • the housing and the helical press body cylindrical.
  • This has the advantage of one particularly easy to manufacture.
  • An alternative embodiment provides that To form the housing and the helical pressing body conical.
  • possible signs of wear on the housing or on Press body can be compensated for by an axial displacement of the press body can.
  • the material can be optimally compressed Invention can be achieved by means of a conically shaped core of the compact.
  • the largest diameter of the cone is at the discharge end, the smallest Diameter in the area of the feed opening. This allows a very high Achieve compaction of the material.
  • a perforated floor is pressure stable and can be cleaned easily.
  • a funnel Arrange feed of the material to be dehumidified above the extruder.
  • a roller with driver rods is arranged in this funnel.
  • the Driving rods have the task of the material, which is partly used as a filter cake gets into the hopper to shred for better feeding to the extruder is possible.
  • the funnel is advantageously provided with lattice bars, one cause a further improvement in the size reduction of the material.
  • a further embodiment of the invention provides for the liquid that is made the perforated base emerges to provide a receiving funnel.
  • the removal of the Liquid from the receiving funnel is preferably carried out by means of an ejector. Both the ejector and a flushing device can be used with the liquid also attached to the material, d. H. usually operated with oil.
  • the device for dehumidifying material consists of a housing 10 which is conical and which has a feed opening 11 and a discharge opening 12 having.
  • a housing 10 which is conical and which has a feed opening 11 and a discharge opening 12 having.
  • a helical one Press body 13 This is a drive unit 14 in Rotation offset.
  • the drive unit 14 is via a Flanged disc 15 attached to the housing 10.
  • In the lower part of the Housing 10 has openings in the form of a sieve plate 16. Underneath is a drip pan 17 with an outlet 18 for Collection of the escaping liquid provided.
  • the material to be dehumidified is fed through the feed opening 11 filled and due to the conical shape of the Press body and the rotation to the discharge opening transported and compacted at the same time.
  • the compression causes dehumidification of the material.
  • the exiting Liquid is drained off through the sieve tray.
  • the material to be dehumidified is in the essential to metal chips during machining accumulate and a high level of moisture, in particular Have lubricant emulsion.
  • Both the housing 10 and the pressing body 13 consist of a wear-resistant material or are with a wear-resistant surface. Should it go anyway a certain amount of wear and tear at the time, then this can Wear by adjusting the press body, d. H. by Moving the compact in the axial direction compensated become.
  • a variant of the device for dehumidifying material shows Figure 2.
  • the pressing body 13 is a cylindrical element.
  • the housing 10 is a cylindrical housing.
  • the compression of the supplied material is due to the cone-shaped core 19 of the pressing body 13. Also here the housing 10 is provided with a sieve plate 16 through which the liquid can leak out.
  • the material to be dehumidified passes through the feed opening 11 into the press room, via the The dehumidified material is removed from the discharge opening 12.
  • the size of the discharge opening 12 also 'has an influence on the dehumidifying effect.
  • a very small one Discharge opening will cause, especially in the front
  • a high pressure is created in the area of the compact Degree of dehumidification can be increased.
  • the size of this Discharge opening can be done by suitable means, such as. B. Locking slide or the like can be varied.
  • FIG 3 shows the device for dehumidifying material according to Figure 1 with the housing 10.
  • a funnel 20 put on This funnel is to the cross of the Housing 10 arranged laterally offset. This has the advantage that the material fed is better grasped by the screw press becomes.
  • the material to be fed is, for example, a filter cake Metal shavings. So that this filter cake is not in the Hopper 20 accumulates is a shredder intended. As shown in FIG. 4, this consists of a rotatable roller 28 on which driver rods 22 are arranged are. Lattice bars 23 are located below the roller are firmly connected to the funnel 20. With that Rotation of the roller 28, the driver rods 22 through the Lattice bars through, so that a reliable transport of the Material is guaranteed.
  • the top view according to Figure 4 shows that the individual Driver rods 22 at various locations on roller 28 are arranged and each between a pair of lattice bars 23 reach through.
  • the funnel 20 is at the top Level sensor 27 arranged, which indicates an overfill.
  • a receiving funnel 24 for the Liquid provided below the press.
  • This liquid for example oil, is partially dirty, so that there is a risk that Form deposits on the receiving funnel 24.
  • To avoid these deposits are provided with a rinsing device 25.
  • This flushing device will oil the inner wall of the Receiving funnel 24 passed and the dirt discharged.
  • the liquid is transported away via the pipeline 29 by means of an ejector 26.
  • This ejector is also made with oil operated. This means that the drained fluid is back directly the process, d. H. a cooling emulsion system for Can be made available.
