Definitions

  • the invention relates to a device for dehumidifying material according to the preamble of the main claim.
  • filter presses in the form of plate filter presses are known.
  • the material to be dehumidified is introduced between filter discs and the moisture is removed under high pressure. This discontinuous process is very complex.
  • the dehumidified material must be removed, the device cleaned and new material added.
  • the invention has for its object to provide a device for dehumidifying material, which is simple in construction and enables continuous operation.
  • the main advantage of the invention is that a compact system is created which operates continuously, with oil and emulsion separation or water separation being possible in particular when dehumidifying metal chips.
  • the invention works on the principle of an extruder and is able to dehumidify very large amounts of material in a short time.
  • the housing and the helical pressing body are cylindrical. This has the advantage of being particularly easy to manufacture.
  • An alternative embodiment provides for the housing and the helical pressing body to be conical. The advantage here is that any signs of wear on the housing or on the pressing body can be compensated for by an axial displacement of the pressing body.
  • an optimal compaction of the material can be achieved by means of a conically shaped core of the pressed body.
  • the largest diameter of the cone is at the discharge end, the smallest diameter in the area of the feed opening. This enables a very high compression of the material to be achieved.
  • the housing or the separator element is advantageously provided with a perforated base for easy removal of the liquid.
  • a perforated floor is pressure-stable and can be easily cleaned.
  • Another variant of the helical compact shows a variable pitch.
  • the slope of the helix toward the discharge opening expediently decreases. With this measure, too, a higher compression of the material can be achieved.
  • a hopper for feeding the material to be dehumidified above the extruder.
  • a roller with driver bars is arranged in this funnel.
  • the driving rods have the task of crushing the material, which partly gets into the funnel as a filter cake, so that a better feed to the extruder is possible.
  • the funnel is advantageously provided with lattice bars, which bring about a further improvement in the size reduction of the material.
  • Another embodiment of the invention provides for a receiving funnel to be provided for the liquid which emerges from the perforated base.
  • the liquid is preferably transported out of the receiving funnel by means of an ejector.
  • Both the ejector and a rinsing device can with the liquid that also adheres to the material, i. 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. There is a helical pressing body 13 in the housing. This is set in rotation via a drive unit 14. The drive unit 14 is fastened to the housing 10 via a flange disk 15. In the lower area of the housing 10 there are openings in the form of a sieve plate 16. Below this is a collecting trough 17 with an outlet 18 for collecting the escaping liquid.
  • the material to be dehumidified is filled in via the feed opening 11 and, due to the conical shape of the pressing body and the rotation, is transported to the discharge opening and compressed at the same time.
  • the compaction dehumidifies the material.
  • the escaping liquid is discharged through the sieve tray.
  • the material to be dehumidified is essentially metal shavings that arise during machining and have a high proportion of moisture, in particular lubricant emulsion.
  • Both the housing 10 and the pressing body 13 consist of a wear-resistant material or are provided with a wear-resistant surface. Should there nevertheless be a certain amount of wear in the course of time, this wear can be compensated for by adjusting the pressing body, ie by moving the pressing body in the axial direction.
  • FIG. 2 shows a variant of the device for dehumidifying material.
  • the pressing body 13 is a cylindrical element.
  • the housing 10 is a cylindrical housing.
  • the housing 10 is provided with a sieve plate 16 through which the liquid can escape.
  • the material to be dehumidified reaches the baling chamber via the feed opening 11, and the dehumidified material is discharged via the discharge opening 12.
  • the size of the discharge opening 12 also has an influence on the dehumidifying effect.
  • a very small discharge opening will result in high pressure, particularly in the front area of the compact, which can increase the degree of dehumidification.
  • the size of this discharge opening can be determined by suitable means, such as. B. slide gate or the like can be varied.
  • FIG. 3 shows the device for dehumidifying material according to FIG. 1 with the housing 10.
  • a funnel 20 is placed on this housing. This funnel is laterally offset from the axis cross of the housing 10. This has the advantage that the material fed is better gripped by the screw press.
  • the material to be fed is, for example, a filter cake made of metal chips.
  • a comminution device is provided so that this filter cake does not accumulate in the funnel 20.
  • this consists of a rotatable roller 28 on which driver rods 22 are arranged.
  • Lattice bars 23 are located below the roller. These are firmly connected to the hopper 20. Thus, when the roller 28 rotates, the driver bars 22 each pass through the bars, so that a reliable transport of the material is ensured.
  • the top view according to FIG. 4 shows that the individual driver bars 22 are arranged at different points on the roller 28 and each reach through between a pair of bars 23.
  • a fill level sensor 27 is arranged at the upper area, which indicates an overfill.
  • a receiving funnel 24 for the liquid is provided below the press. This liquid, for example oil, is partially contaminated so that there is a risk of deposits forming on the receiving funnel 24.
  • a rinsing device 25 is provided. This flushing device directs oil to the inner wall of the receiving funnel 24 and the dirt is discharged.
  • the liquid is transported away via the pipeline 29 by means of an ejector 26.
  • This ejector is also operated with oil. This means that the derived liquid can again be made available to the process, ie a cooling emulsion system.
