Definitions

  • the invention relates to equipment for the separation of liquids and solids in centrifuges, in particular Tellerseparatoren with automatic discharge.
  • the invention particularly relates to a paste deflecting ring with an annular baffle for a self-discharging centrifuge and the self-discharging centrifuge.
  • Tellerseparatoren are centrifuges, equipped with a central inlet for the suspension, located in the drum conical plates, which are used by the existing centrifugal force and the short sedimentation as a separator for fine particles.
  • the deposited particles slide along the plates into the solids collection space toward the largest diameter of the drum.
  • the clarified liquid is depressurized via an overflow weir or by means of a trained as a pump impeller so-called.
  • Gripper dissipated under pressure.
  • drum disk separators For low solids contents, closed drum disk separators are in use which must be manually cleared. For higher solids contents, the drums are equipped with an emptying system which allows the entire contents of the drum to be discharged as solids and liquid as sludge.
  • the DE 198 46 535 Aoffenbarteine centrifuge with a largely lossless solids recovery is made possible from a centrifuged.
  • the separated from the centrifuge drums solid is collected in a bag, which is inserted into a container, the centrifuge drum protrudes into the interior of the container and into an upper opening of the bag.
  • solids can be collected lossless from the centrifuged.
  • the WO 95/21697 discloses an apparatus for centrifugal separation, for example for the separation of sugar, which has, inter alia, a deflector.
  • the invention now relies on the application to a self-discharging centrifuge for the processing of highly concentrated pastes with a hanging drum with two or more discharge slots, which allows a gentle deflection of the ejected from the discharge slot solid into a receptacle of the centrifuge.
  • the paste discharge takes place under centrifugal acceleration in the horizontal direction on a circular circumference and could be collected in an annular container.
  • the invention achieves the object by the article of claim 1, comprising a paste deflecting ring and a connected or detachable paste container which is capable of receiving the paste from a plurality of drum emptying.
  • This ring is designed so that a deflection is associated with the lowest possible product losses.
  • the deflection ring is formed with a jacket cooling.
  • the cooling jacket is e.g. a double wall on the outer circumference of the Umlenkringes, which can be dunchströmt by a heat exchange medium.
  • the deflecting ring is characterized in that the inner contour of the baffle wall is formed directly below the impact surface, in particular over any longitudinal section of the deflecting ring, circular or parabolic.
  • the deflection is made even more gentle on the product and further reduces the shear.
  • the deflection ring is designed so that the baffle wall in the area below of the discharge slot has a curved inner contour, seen in geometric longitudinal section, with a radius of curvature of> 20 mm, preferably from 30 to 50 mm.
  • the latter curved wall surface can also be designed according to a curve with a variable radius over the course of travel.
  • the baffle wall of the deflection ring has an angle of attack y to the horizontal of 3 to 30 °, preferably 5 to 15 °, in the region above the opening width of the discharge slot.
  • a preferred variant of the deflection ring is characterized in that the tangent of the inner contour of the baffle surface in the region below the deflection contour of the deflection ring relative to the vertical in the geometric longitudinal section seen an angle of attack 3 to 30 °, preferably from 5 to 15 °.
  • the vertical is parallel to the axis of rotation of the drum.
  • the deflection ring has in a preferred variant at its lower end a tear-off edge, which is optionally undercut.
  • the deflecting ring is in particular connected in one piece with a collecting container or particularly preferably separably connected to the collecting container of the centrifuge.
  • the product-contacting surface of the deflecting ring is provided with a lubricious coating, in particular made of PTFE or metal alloys.
  • the deflection ring has one or more nozzles for the injection of liquid nitrogen.
  • nozzles are in particular distributed on the circumference of the deflection ring below the impact surface, which corresponds to the opening width of the discharge slot.
  • the collecting container is preferably configured cylindrically conically narrowing downwards or downwards.
  • the conical constriction of the collecting container facilitates the discharge of e.g. frozen product from the container.
  • the upper edge of the container is in particular designed so that below the preferably attached spoiler lip of the deflection ring results in a low-flow turbulence.
  • the product-contacting inner surfaces of the collecting container are also provided in a preferred embodiment with a lubricious coating, in particular of PTFE or metal alloys.
  • a bag of flexible material is particularly preferably inserted, which can be fixed in particular by means of negative pressure to the container walls.
  • Suitable materials for the bag are all film plastics, in particular polypropylene, polyethylene, polyvinyl chloride.
  • the collecting container is formed in a preferred further form of the centrifuge with a tempering device, in particular with a jacket cooling.
  • the collecting container preferably additionally has means for transport, in particular by means of conveyor devices.
  • the upper opening of the collecting container is particularly preferably designed as a partial flange.
  • the receptacle is e.g. closed with a lid and designed so that docking with other procedural devices, in particular to a dissolving vessel is possible.
  • the collecting container is designed jacket cooling.
  • one or more nozzles may be mounted, through which liquid nitrogen can be introduced into the gas space in the vicinity of the rotating drum in order to suppress the heating of the discharge space by air friction.
  • the container may be made of metallic or non-metallic materials.
  • the container can be arranged detachably or non-detachably in a frame which is transported or stackable by means of industrial trucks.
  • the container can be provided with a lid or equipped with an automatic opening slide and be suitable for loading dissolving boilers.
  • the container can be equipped with a mashing or melting device, which allows the content to be conveyed as a flowable suspension in the dissolving vessel.
  • the container may also be e.g. be equipped with jacket cooling for use in biotechnology.
  • the discharge of a biological paste obtained in the fractionation of human blood plasma is carried out from a centrifuge drum 14 with an outer diameter of 468 mm at a drum speed of 7000 l / min and deflection of the blood plasma paste by a Pasteumlenkring 4.
  • the centrifuge 1 has a drive part 13 for driving the drum 14 with a supply line 11 for the plasma.
  • the drum 14 is suspended in a separable lower part of the centrifuge 1, which comprises the jacket housing 10, with feed lines 19 and discharges 22 for cooling liquid and feed lines 9 for liquid nitrogen, the deflection ring 4 and the collecting container 7.
  • the collecting container has a cooling jacket 16 with supply lines 20 and discharge lines 21 and welded transport tabs 18.
  • the drum 14 also has an outlet 12 for the clarified liquid. Fig.
  • the angle ⁇ above the opening width of the discharge slot 3 is also inclined by 15 ° to the horizontal, so that the impact surface 8 itself and the overlying area in the projection form a straight line.
  • the discharged paste is deflected by a, viewed in longitudinal section, circular contour with a radius of curvature r of 45 ° in the direction of the container bottom of the collecting container 7.
  • the Pasteumlenkring 5 has at its lower end a spoiler edge. 6
