Definitions

  • the present invention relates to a centrifuge with a centrifugal drum, which comprises a lower drum part, a centrifugal chamber floor, a drum cover and a piston slide, the piston slide being axially movably mounted in the lower drum part and by springs supported on the lower drum part in a closed position for solid outlet openings provided in the jacket region of the lower drum part held and can be moved into an open position for the solids outlet openings by a control arm which can be introduced into an opening chamber arranged between the piston slide on the one hand and the centrifugal chamber floor on the other hand.
  • springs made of rustproof materials are used in centrifuges or separators of the generic type.
  • the present invention is based on the object of designing a centrifuge of the generic type in such a way that only a relatively small installation space is required for accommodating the springs while observing all hygienic requirements.
  • the springs are made of unalloyed spring steel and on the one hand in the piston valve and other on the other hand, sleeves made of corrosion-resistant material are encapsulated in bores in the bottom region of the lower drum part.
  • FIG. 1 shows a sectional illustration of a centrifuge according to the invention with a piston slide
  • Figure 2 shows the detail labeled "II" in Figure 1 on an enlarged scale.
  • centrifugal drum 1 shows a centrifuge with a centrifugal drum 1, which comprises a lower drum part 2, a centrifugal chamber floor 3, a drum cover 4 and a piston slide 5, the piston slide 5 being axially movably mounted in the lower drum part 2.
  • the centrifuge designed as a separator is suspended from a machine frame 10, with centrifugal material being fed through an inlet pipe 12 opening into the centrifugal drum 1 from above.
  • a pipe 13 is connected concentrically to the inlet pipe. ordered so that a control fluid, for example sterile control air, can be fed through the space 14 between the inlet pipe 12 and the pipe 13.
  • a control fluid for example sterile control air
  • the intermediate space 14 opens into a passage 15 in the distributor 16 and this in the opening chamber 8.
  • Centrifuged material is collected in a container 16 which indicates the hanging centrifugal drum 11.
  • the liquid phase is discharged via the peeling disc 17 and the line 18.
  • the piston slide 5 is shown in the right half of FIG. 1 in a closed position, ie, in this closed position the solid outlet openings 6 provided in the jacket region 2a of the lower drum part 2 are sealed by the piston slide 5, in the left half of FIG. 1 the piston slide is 5 shown in the open position, ie in this position the solids outlet openings 6 of the lower drum part 2 are opened.
  • the opening position is achieved in that a pressure is built up by introducing a control medium, preferably compressed air, into an opening chamber 8, which is formed between the control piston 5 on the one hand and the centrifugal chamber floor 3 on the other hand, which overcomes the forces of the springs 7 and thus the piston slide 5 moved into the open position shown in the left half of Figure 1. Conversely, if the opening space 8 is depressurized again, the springs 7 move the piston slide 5 back into the closed position shown in the right half of FIG.
  • a control medium preferably compressed air
  • the springs 7, which according to the invention are made of an unalloyed spring steel, are encapsulated by sleeves 10 made of a corrosion-resistant material in the piston slide 5 and in the bores 9 of the bottom region 2b of the lower drum part 2.
  • the sleeves 10 are advantageously closed on their ends at their ends projecting into the piston slide 5, so that the springs 7 with their ends projecting into the piston slide 5 are supported on the end faces 10a of the sleeves 10 there.
  • the sleeves 10 are sealed off from the bores 9 by at least one sealing ring 11 each.
  • Figure 2 clearly shows that the ends of the springs 7 protruding into the bores 9 of the lower drum part 2 are guided on guide pins 12, while the remaining area of the springs 7 is secured against lateral deflections by the sleeves 10 mentioned.
  • springs 7 made of unalloyed spring steel there is the possibility of a particularly space-saving construction, so that despite the relatively small dimensions of the springs 7, large closing forces for the piston slide 5 can be achieved, and a relatively large piston slide stroke can also be achieved with comparatively small dimensions for the springs 7.
  • the encapsulation of the springs 7 ensures highly effective insulation of the spring chamber from the sterile room, and abrasion due to friction or centrifugal force as well as the effects of corrosion on the product are reliably avoided.

Abstract

L'invention concerne une centrifugeuse (ou un séparateur) comprenant un panier centrifuge (1) et un tiroir à piston (5) commandé par ressorts et axialement mobile. Le tiroir à piston (5) qui est guidé dans une partie inférieure de panier (2), est maintenu dans une position de fermeture, dans laquelle les orifices de sortie de solides (6) pratiqués dans la zone externe (2a) de la partie inférieure de panier (2) sont fermés, par des ressorts (7) qui s'appuient sur la partie inférieure de panier (2). En introduisant un agent de commande dans un espace ouverture (8) situé entre le tiroir à piston (5) et le fond (3) du compartiment d'essorage, on peut créer une pression qui vient à bout des tensions des ressorts de telle façon que le tiroir à piston (5) se déplace axialement pour libérer les orifices de sortie de solides (6). Selon l'invention, les ressorts (7) sont réalisés dans un acier à ressorts non allié et sont complètement encapsulés par des douilles (7) réalisées dans un matériau résistant à la corrosion. Cela permet d'obtenir des ressorts (7) de très petites dimensions, qui sont intégrés dans la structure totale dans le cas de grandes tensions de ressorts et donc de grandes forces de fermeture. On obtient également une isolation absolue du compartiment de ressorts vis-à-vis du compartiment stérile.
