Definitions

  • the present invention relates to a centrifuge with a centrifugal drum, which a drum base, a centrifugal chamber floor, a drum lid and a piston slide, wherein the piston slide in the drum base mounted axially movable and supported on the drum base springs in a closed position for mounted in the shell region of the drum base Held solids outlet openings and through a in between the spool on the one hand and the centrifugal chamber bottom on the other hand arranged opening chamber einleitbares control medium against the action of the springs in a Opening position for the solids outlet openings is movable.
  • centrifuges or separators of the generic type Type springs used which are made of stainless materials.
  • the present invention is based on the object, a centrifuge of the generic To design a way that in compliance with all hygienic requirements only a relatively small space for the accommodation of the springs needed becomes.
  • a centrifuge with a centrifugal drum 1 is shown, which a Drum lower part 2, a centrifugal chamber bottom 3, a drum cover 4 and a piston slide 5 comprises, wherein the piston slide 5 in the drum base 2 is mounted axially movable.
  • the centrifuge designed as a separator is suspended on a machine frame 10, being centrifuged by an opening from above into the centrifugal drum 1
  • Inlet pipe 12 is supplied.
  • Concentric to the inlet pipe, a tube 13 is arranged, so that through the intermediate space 14 between the inlet pipe 12 and a control fluid, e.g. sterile control air, can be supplied.
  • a control fluid e.g. sterile control air
  • the gap 14 opens into a passage 15 in the manifold 16 and this in the Opening chamber 8.
  • Centrifugal material is in a hanging centrifugal drum 11 indicating container 16 caught.
  • the liquid phase is discharged via the peeling disk 17 and the line 18.
  • the spool 5 is in the right half of Figure 1 in a closed position shown, that is, in this closed position by the spool 5 in the jacket area 2a of the drum base 2 provided solid outlet openings. 6 tightly closed, in the left half of Figure 1, the spool 5 in the open position shown, i.e., in this position are the solids exit ports 6 of the drum base 2 is opened.
  • the piston slide 5 becomes the fifth held by several springs 7 in its closed position.
  • the open position is achieved in that by introducing a control medium, preferably compressed air, in an opening chamber 8, between the Control piston 5 on the one hand and the centrifugal chamber bottom 3 on the other hand is formed a pressure is built up, which overcomes the forces of the springs 7 and thus the Piston slide 5 in the apparent from the left half of Figure 1 opening position emotional. Conversely, the opening space 8 made depressurized again, move the springs 7 the spool 5 again in the from the right half of Figure 1 apparent closed position.
  • a control medium preferably compressed air
  • the springs 7, which are made according to the invention of a non-alloyed spring steel, encapsulated by one hand in the spool 5 and on the other hand in holes 9 of the bottom portion 2b of the drum base 2 protruding sleeves 10 made of a corrosion-resistant material.
  • the sleeves 10 are advantageously frontally closed at their projecting into the spool 5 ends, so that the springs 7 are supported with their protruding into the spool 5 ends of the local stimulating floors 10 a of the sleeves 10.
  • the sleeves 10 are in their projecting into the holes 9 of the drum base 2 Sections through at least one sealing ring 11 in relation to the Holes 9 sealed.
  • Figure 2 clearly shows that in the holes 9 of the drum base 2 protruding ends of the springs 7 are guided on guide pins 12, while the remaining area of the springs 7 through the mentioned sleeves 10 against lateral deflections is secured.
  • springs 7 made of unalloyed spring steel there is the possibility a particularly space-saving design, so that despite relatively small Dimensions of the springs 7 reaches large closing forces for the piston valve 5 be, as well as a relatively large spool stroke to realize in comparison small dimensions for the springs 7. Due to the encapsulation of the springs 7 is a highly effective isolation of the spring chamber to the sterile cavities out ensures and abrasion due to friction or centrifugal force as well as corrosion influences on the product are safely avoided.
