Definitions

  • the invention relates to a pusher centrifuge according to the Preamble of the main claim.
  • a push centrifuge is for example from DE 89 08 470 U1 known and used for the solid and liquid separation of materials.
  • the known centrifuge consists of a stationary Machine frame, an input funnel connected to it and Solid material outlet, as well as a liquid outlet and one cylindrical housing for a drum and a liquid-tight cylinder pan. It is rotating in this tub driven, equipped with lifting and lowering moving floor Recording drum arranged.
  • centrifuges can also have disadvantages exhibit.
  • centrifuging it can happen that long Materials such as rods, rags, fleeces in the Centrifuge.
  • the push floor of the centrifuge is with the Material guide surfaces connected by webs, on these webs can possibly tilt these materials or get stuck. In this case it happens in the centrifuge Blockages, resulting in malfunctions and standstill.
  • the object of the invention is to provide a centrifuge which has a trouble-free running when processing various Materials guaranteed.
  • a centrifuge according to the invention its moving floor and Material lifting surface separated from each other a lifting and Execute lowering movement or an up and down movement and driven separately from each other has several advantages on. If materials such as rods, rags, fleeces are centrifuged, these materials do not cause constipation, interference and The centrifuge stops.
  • the centrifuge works fully automatically, the manual emptying not applicable. High personnel costs are saved. The lifespan of the Centrifuge is extended considerably. Wear and damage is reduced. There will be repair costs and material costs saved.
  • the centrifuge is used for the extraction of Residual material provided a proboscis.
  • This extends into the Recording drum and is longitudinal in an advantageous embodiment slidably arranged. This longitudinal displacement can over a Actuator.
  • the suction has a fan and a Solid gas separation.
  • the Material guide surface arranged a distributor.
  • This distributor has the task of evenly feeding the material flow over the distribute the entire circumference of the take-up drum.
  • This distributor can be rotated to optimally accommodate certain types of material to distribute. But it can also be fixed to the material guide surface be arranged.
  • this type of fastening for certain Types of material is particularly suitable.
  • a development of the invention provides for the take-up drum which is usually provided with an armored ring with a sieve equip.
  • This sieve has the advantage that when you enter it Material is dehumidified and the moisture can be removed quickly can.
  • the tub which has a drain for the centrifuged Has liquid can in an advantageous manner with a Be flushing liquid inlet. This gives you the opportunity to clean this tub at certain intervals. If the Flushing liquid inlet is arranged tangentially to the tub a cleaning effect that covers the entire inner surface of the The tub is wetted with cleaning fluid and is even Cleaning guaranteed.
  • the walking floor is in another advantageous embodiment of the invention on three guide bolts stored. This will cause the push floor to tilt or tilt effectively prevented.
  • a liquid-tight trough 26 is located in the receiving housing 27 connected to the machine frame 10 installed with the after outside leading liquid outlet 13 is connected.
  • the rotating driven Recording drum 21 arranged, which can be raised and lowered Moving floor 24, 25 is provided, which with the receiving drum 21st rotates.
  • the push floor 25 has one from the center of the centrifuge, Bottom surface 24 designed at an angle to the outside and is by means of the guide rods 28 in a manner shown vertically displaceable in the bottom 14 of the outer jacket 16 of the Recording drum 21 performed. The latter is with the rows of holes 17th provided to escape the spun liquid and into the to let liquid-tight tub 26 arrive.
  • the receiving drum 21 is at a distance from the outer jacket 16 still with the lower armored jacket 15 and the upper (inner) Coat part 19 provided.
  • the lower armored jacket 15 consists of a thick-walled material with a hard surface, during the upper casing part 19 is formed from slotted sieves.
  • the materials filled in the input hopper 20 are first shown in offset from the center of the centrifuge and evenly in the peripheral radial Distributed directions, the material guide surface 23rd contributes. Due to the centrifugal force, the materials collect initially in the lower part of the take-up drum 21, and are consequent the centrifugal force and the material guide surface 23 to the lower Armored jacket 15 hurled to create a ring there and then by means of the sliding floor 25 which can be raised and lowered periodically to be pushed up.
  • the moving floor 25 is not with the Material guide surface 23 connected and separately leads a lifting and Lowering movement or an up and down movement.
  • the material guide surface 23 is driven via Drive devices 29, 30, the sliding floor 25 is driven via drive device 31.
  • This drive device is, for example, an electric motor Actuator or hydraulic drive. Of course it is possible to use any drive type.
  • the material guide surface 23 and the sliding floor 25 can be parallel be controlled and thus execute a common hub, it there is also the possibility to control the elements separately in order to increase or decrease the annular gap between these two elements downsize.
  • FIG. 2 shows a variant of that shown in FIG. 1 Pusher centrifuge.
  • This suction consists of a proboscis 32, which extends partially into the take-up drum.
  • a suction line 33 is arranged, which leads to a suction fan 34.
  • the solids are separated from the in the suction fan Blower air.
  • the proboscis is arranged to be longitudinally displaceable.
  • the Longitudinal displacement takes place via a drive 35
  • a flushing liquid inlet 36 is provided in the tub 26. This influx enters the tub tangentially, creating a spiral running flushing liquid flow, which has a high flushing effect having.
  • the whole Thrust centrifuge which standing in Figure 1 as well as in Figure 2 is arranged to design in a lying arrangement. For this only the frame 11 is slightly modified.
  • FIG. 3 shows a detailed representation of the material entry. At this Material entry is the feed hopper 20 and Material guide surface 23 can be seen. On the material guide surface 23 a distributor 37 is provided. This distributor is about one Ball bearing 38 with the one shown here only as a cylinder Material guide surface connected.
