Definitions

  • the invention relates to a centrifuge according to the preamble of claim 1. Die The invention further relates to a method for operating an inventive Centrifuge.
  • the centrifuge shown in DE-A-28 22 478 has a centrifugal drum a spool on which a chamber is assigned, which via channels in a spindle is connected to a hydraulic system.
  • the enema of the product takes place via a central inlet pipe from above.
  • the spindle is on the Bottom of the centrifugal drum.
  • DE-A-2808677 describes the use of a gaseous medium as a control fluid known, the feed channel concentrically the inlet pipe for the Slingshot is assigned.
  • a generic centrifuge is known from US-A-4044945. This too However, construction does not guarantee that the product area for hygiene reasons from the drive area of the centrifuge and the control elements of the drive as well the controls of the control fluid supply outside the drum (valves etc.) is separated.
  • the object of the invention is the generic centrifuge to further develop that a gaseous medium can be used as a control fluid, to uncomplicated handling and use under sterile conditions enable. It should preferably also be possible to use the invention in the product area from the drive area and its controls and preferably also separate from the controls for the control fluid supply.
  • control fluid supply line and the centrifugal material supply line thus together into the Centrifugal drum can be performed and run directly next to each other in this way a structurally separate supply of the control fluid can be avoided.
  • the invention is particularly suitable for a centrifuge in which the centrifugal drum hanging on a centrifuge frame, the inlet pipe for the Centrifuged material and the feed channel for the control fluid from above into the Centrifugal drum are guided.
  • a separate supply of the control fluid from below into the drum is not practical, as it may be necessary to remove the solids separated during the separation process collect in a sterile container below the drum. This is through the control fluid supply "from above" is significantly simplified.
  • a double-walled pipe offers the advantage of a particularly space-saving accommodation of the control fluids the centrifugal feed line.
  • the control fluid supply serves to move a movable piston valve Opening and closing of solids discharge openings in the centrifugal drum actuate.
  • a gaseous medium preferably sterile air
  • sterile air is used as the control fluid, which is easy to handle and for use as a control medium is well suited under sterile conditions, since direct contact with the Centrifugal contamination of the same is prevented.
  • Fig. 1 shows a centrifuge designed as a separator, which is known per se Way a downward centrifugal drum 2 to separate a Has centrifuged goods in different components.
  • the centrifuge or the Centrifugal liquid is poured in through a central inlet pipe 4 in the centrifugal drum 2 passed.
  • the centrifugal drum 2 is on a centrifuge frame 6 with a lower one Frame approach 8 hung.
  • the drive section 10 of the centrifuge - which in can be trained in a known manner and therefore not detailed here is shown - is above the centrifugal drum 2 in and / or on the centrifuge frame 6 is arranged and is - also not shown in detail here - Sealing section 12 sealed in the frame extension 8 against the centrifugal drum 2.
  • the centrifugal drum 2 is thus in addition to its drive gate whose controls are structurally separated.
  • a container lid 14 is flanged to the lower end of the frame extension 8, which is penetrated in the middle by the inlet pipe 4.
  • the container lid 14 points here a substantially radially formed bore 16, which serves as a discharge channel for one derived from a peeling chamber 20 by means of a peeling disc 18 Liquid phase from the centrifugal drum 2 is used.
  • the bore 16 opens into one Drain pipe 22.
  • a centrifugal drum 2 On the container lid 14 is a centrifugal drum 2 in its upper region Surrounded upper container jacket 24 formed as the top of a here conical container 26 is used for solids absorption, the lower section 28 of the container can be removed downwards from the centrifuge and in one Container frame 30 stands.
  • the actual centrifugal drum 2 has a feed pipe 4 surrounding it Distributor 32 with a plate pack 34 attached to the outside of the distributor 32.
  • the plate pack 34 is in a conical up and down here constricting centrifugal chamber 36, the top of a conically shaped Drum cover 38 and downwards from one molded onto the distributor 32 at the bottom Centrifuge chamber floor 40 is limited.
  • the drum cover 38 is in one Lower drum part 42 inserted and in the lower drum part 42 with a locking ring 44 screwed.
  • a displaceably guided, annular piston slide 46 arranged here with an essentially L-shaped wall cross section, an opening chamber 48 towards the top and a closing chamber towards the bottom 50 adjacent.
  • the lower wall serves as the lower lock chamber floor 52 of the lower drum part 42.
  • the opening chamber 48 is between the spool 46 and the lower one Wall of the distributor 32 or the centrifugal chamber floor 40 is formed.
  • the Control fluid is fed into the opening chamber 48 via a control fluid supply line 58 in the distributor 32.
  • the control fluid feed line 58 opens into an annular ring surrounding the feed pipe 4 Feed channel 60 between the inner wall of the distributor 32 and the in the feed pipe 4 inserted into the distributor 32.
  • the inner wall of the distributor 32 and the wall of the inlet pipe 4 form a kind of "pipe with double wall” , with the actual supply channel 60 for the control fluid being the feed pipe 4 concentrically surrounds the centrifuge.
  • the distributor 32 of the centrifuge runs through it from the upper end region of the centrifuge frame 6 up to the lock chamber bottom 52 in one piece.
  • this element is preferably composed of several parts.
  • an axial Connection 62 the supply of the centrifugal material into the inlet pipe 4.
  • a radial here outward port 64 is used to feed the Control fluids - especially the supply of sterile control air - in the surrounding the inlet pipe Feed channel 60.
  • the centrifugal material is fed in through the connection 62 and the feed pipe 4 and through an axial bore 66 of the distributor 32 and a bore 68 in the centrifugal chamber floor 40 in the centrifugal chamber 36. Solids are made discharged into the centrifugal chamber 36 through the openings 56, liquid phases through the peeling chamber 20 with the peeling disk 18.
  • the control air is supplied as control fluid through the connection 64 into the inlet pipe 4 guided concentrically surrounding feed channel 60.
  • the control air flows from there into the control fluid supply line 58 and from there into the opening chamber 48 with a correspondingly large pressure purchase structure in the opening chamber 48 Piston slide 46 pressed down against the spring force of the closing springs 54, which opens the solids outlet openings 56 (left section of FIG. 1).
  • a Lowering the pressure in the opening chamber 48 results the spring force of the closing springs 54 in a displacement of the piston slide 46 upwards, which closes the solids outlet openings 56 again.
