Definitions

  • the invention relates to a push centrifuge according to the preamble of the main claim.
  • a push centrifuge is known for example from DE 89 08 470 U1 and is used for the solid and liquid separation of materials.
  • the known centrifuge consists of a stationary machine frame, an input hopper and solid material outlet connected to it, as well as a liquid outlet and a cylindrical receiving housing for a receiving drum and a liquid-tight cylinder trough.
  • the rotating drum which is equipped with a lifting and lowering moving floor, is arranged in this heat.
  • centrifuges can also have disadvantages.
  • When centrifuging it can happen that long materials, such as rods, rags, fleeces, get into the centrifuge.
  • the push floor of the centrifuge is connected to the material guide surfaces by means of webs. Under certain circumstances, these materials can become jammed or get stuck on these webs. In this case, there are blockages in the centrifuge, resulting in malfunctions and standstill.
  • the object of the invention is to provide a centrifuge which ensures trouble-free operation when processing a wide variety of materials.
  • a centrifuge according to the invention the push floor and material guide surface of which perform a lifting and lowering movement or an up and down movement separately and are driven separately from one another, has various advantages. If materials such as rods, rags, fleeces are centrifuged, these materials do not cause blockages, faults and the centrifuge to stop.
  • the centrifuge works fully automatically and there is no manual emptying. High personnel costs are saved. The lifespan of the centrifuge is extended considerably. Wear and damage is reduced. Repair costs and material costs are saved.
  • a suction nozzle is provided for the extraction of residual material. This extends into the take-up drum and, in an advantageous embodiment, is arranged to be longitudinally displaceable. This longitudinal displacement can take place via an actuator.
  • the suction has a blower and a solid gas separation.
  • a distributor is arranged on the material guide surface.
  • This distributor has the task of distributing the supplied material flow evenly over the entire circumference of the take-up drum.
  • This distributor can be rotatably mounted in order to optimally distribute certain types of material. But it can also be fixed to the material guide surface.
  • this type of fastening is particularly suitable for certain types of material.
  • a further development of the invention provides for the receiving drum, which is usually provided with an armored ring, to be equipped with a sieve.
  • This sieve has the advantage that the material is dehumidified as soon as it enters and the moisture can be removed quickly.
  • the trough which has an outlet for the centrifuged liquid, can advantageously be provided with a rinsing liquid inlet. This makes it possible to clean this heat at certain intervals. If the rinsing liquid inlet is arranged tangentially to the tub, a cleaning effect is created which wets the entire inner surface of the tub with cleaning liquid and ensures uniform cleaning.
  • the push floor is mounted on three guide bolts. This effectively prevents the moving floor from tipping or tilting.
  • a liquid-tight trough 26 is connected to the machine frame 10, which is connected to the liquid outlet 13 leading to the outside.
  • the rotatingly driven receiving drum 21 Arranged in the liquid-tight trough 26 is the rotatingly driven receiving drum 21, which is provided with a lifting and lowering sliding floor 24, 25 which rotates with the receiving drum 21.
  • the push floor 25 has a bottom surface 24, which is designed obliquely at an angle to the outside from the center of the centrifuge and is guided vertically displaceably in the bottom 14 of the outer jacket 16 of the receiving drum 21 by means of the guide rods 28 in a manner shown in more detail.
  • the latter is provided with the rows of holes 17 in order to allow the spun-off liquid to emerge and to enter the liquid-tight trough 26.
  • the receiving drum 21 is also provided with the lower armored casing 15 and the upper (inner) casing part 19.
  • the lower armored casing 15 consists of a thick-walled material with a hard surface, while the upper casing part 19 is formed from slotted sieves.
  • the materials filled into the feed hopper 20 are first deposited in the center of the centrifuge and distributed evenly in peripheral radial directions, with the material guide surface 23 participating.
  • the materials first collect in the lower part of the take-up drum 21, and as a result of the centrifugal force effect and the material guiding surface 23 are flung to the lower armored jacket 15 in order to create a ring shape there and then to be pushed upwards by means of the periodically lifting and lowering moving floor 25.
  • the push floor 25 is not connected to the material guide surface 23 and carries out a lifting and lowering movement or an up and down movement separately.
  • the materials are conveyed further upwards under the action of centrifugal force and pass beyond the upper edge 22 of the take-up drum 21 in order to get into the space between the liquid-tight container 26 and the take-up housing 27. Then they fall down and leave the centrifuge through the material outlet 12.
  • the material guide surface 23 is driven by drive devices 29, 30, the push floor 25 is driven by drive device 31.
  • This drive device is, for example, an electromotive actuator or hydraulic drive. Of course it is possible to use any type of drive.
  • the material guide surface 23 and the sliding floor 25 can be controlled in parallel and thus carry out a common stroke, it is also possible to control the elements separately in order to enlarge or reduce the annular gap between these two elements.
  • FIG. 2 shows a variant of the push centrifuge shown in FIG. 1.
  • suction is provided for residual material.
  • This suction consists of a suction nozzle 32, which extends in part into the receiving drum.
  • a suction line 33 is arranged on the suction nozzle, which leads to a suction fan 34.
  • the solids are separated from the blower air in the suction fan.
  • the proboscis is arranged to be longitudinally displaceable. The longitudinal displacement takes place via a drive 35.
  • a flushing liquid inlet 36 is provided for flushing the tub 26. This inlet enters the heat tangentially and thus causes a spiral-shaped flow of rinsing liquid, which has a high rinsing effect.
  • the entire pusher centrifuge which is standing in FIG. 1 and in FIG. 2 is arranged to design in a lying arrangement. For this purpose, only the frame 11 is slightly modified.
  • FIG. 3 shows a detailed representation of the material entry.
  • the feed hopper 20 and the material guide surface 23 can be seen at this material inlet.
  • a distributor 37 is provided on the material guide surface 23. This distributor is connected via a ball bearing 38 to the material guide surface shown here only as a cylinder.
