Definitions
- the invention relates to a solid bowl screw centrifuge according to the preamble of claim 1.
- the separator with the plate package is doing on a larger diameter of the Nozzles the concentrate and in the center the clarified phase derived Outside the Tellervols is a solid space formed on both sides by conical Walls is limited.
- the outer diameter of this separator is e.g. in the SU 385 629 or the generic GB 998 669 on a larger radius as the outside diameter of the decanter.
- the invention has the object, the generic centrifuge spallwickehl, that with cost-effective design in a simple way a derivative of the concentrate from the area of the plate to the drum shell out takes place, wherein also resulting from the attachment of the plate packages on the screw body Problems should be avoided.
- the conical section of the disc as well as the opposite to the conical section The disk formed conical drum lid hereby form a double conically tapering solids or concentrate collection space, the one enables a particularly advantageous discharge of the concentrate towards the drum shell, without the attachment of a separately formed, the decanter downstream Separators on the type of the generic prior art necessary would.
- the plate package in a cylindrical portion of the drum space arranged with a substantially constant diameter and the plate package is connected directly upstream of the liquid outlet, wherein it rests on the drum lid and / or arranged on this.
- the plate package rests directly on the drum lid or is attached to this, It does not rotate any more with a differential speed to the drum shell but turns with this one.
- step on the screw in this connected to the liquid-side drum wall plate insert no interfering short circuits between the clear phase collector of the Tellereisatzes and the solids space outside the plate insert on.
- Concentrate space of the plate insert is located on the outside of the plate package, in which the diameter of the drum shell is continuously executable and no extension requirement. In this way it is also possible to separate mixtures which are difficult to clarify, e.g. Mixtures with fine suspended matter.
- the maximum radial extent of the disc is less than that radial extent of the screw blade.
- the derivative is by means of reached a scraper on the first screw blade, which passes through the plate.
- the drum lid is made substantially conical, which a particularly simple attachment of the preferably pre-assembled plate package unit on the drum lid allows, especially the plates of the Tellavers also are preferably formed conical.
- the clear phase collector at a lower Diameter than the outer wall of the screw body is located.
- Fig. 1 shows a solid bowl centrifuge, which in addition to the not here to be explained further components such as the drive A and the machine frame M a centrifugal drum with a drum shell 1 and with a screw. 2 wherein the screw 2 is a screw body 3 and a Schnekken redesign 3 multiple surrounding screw blade 4 includes. Between Worm threads 4 is a conveyor track for conveying / transporting a processed Slippery trained.
- the screw body 3 has a slightly stepped in the rear, cylindrical Section 5a and an adjoining conical tapered section 5b on.
- the cylindrical portion 5a becomes axially at least one of itself in the region of the drum space 6 between the screw body 3 and the Drum shell 1 conical drum lid 7 closed.
- the S to be centrifuged is through the centrally arranged and co-rotating inlet pipe 12 via a distributor 20 in the drum chamber 6 with the screw 2 and the screw shell 2 surrounding drum shell 1 passed.
- a distributor 20 in the drum chamber 6 with the screw 2 and the screw shell 2 surrounding drum shell 1 passed.
- the distributor 20 and the co-rotating Inlet pipe 12 form an advantageous hygienic, largely dense system.
- the worm 2 rotates at a speed slightly lower or higher than the drum 1 and promotes the ejected solid to the conical section out of the drum for solids discharge.
- the liquid flows to the cylindrical portion 5a at the rear end the drum 1 and is derived there.
- the conical plates 11 are substantially conical formed corresponding to the drum cover 7.
- the plate package has a "distributor shaped "holder 10, which has an inner cylindrical portion 10a and an axially adjoining conical section 10b. Between the conical portion 10b and the drum lid 7 are the actual arranged conical plate 11, which preferably by means of spacers are spaced, which are adapted to the particular application (molded Moldings, punctiform spacers, etc.).
- the disc package 9 may be formed be that the supply of the centrifugal material to be clarified takes place radially from the outside (not shown here).
- the derivation of the clear phase is carried out by a manifold 14 at the inner Diameter of the plate 11 in the wall of the cylindrical portion 10b.
- the manifold 14 is preferably at least partially on a smaller Diameter than the outer wall of the screw body 3, which is a more energy-efficient Operating conditionally as arranging the manifold on a larger Diameter, which is also theoretically conceivable.
- the manifold 14 finds an axial continuation in a bore 15 of the drum cover, which in a radially outwardly extending drain 16 for the clear phase opens.
- the concentrate room is located outside on the Tellerpakt 9, the diameter of the drum shell 1 is executed continuously and no extension includes.
- the concentrate is discharged by means of the screw 2, wherein the screw has a Räumansatz 17 for discharging the solid from the concentrate space, which passes through the disc 8.
- the diameter of the drum shell 1 is this area formed substantially constant.
- Applicant's Varipond system can be used (regulating disc 22, which is axially slidable before expiry DE 43 20 265). Also other settings of the mirror as a disc package downstream peeling disc imaginable.
- bracket 10 and / or on the drum cover 7 are also in an advantageous Way at the side facing away from the plates 9 side of the introduction of the centrifuged material formed in the plate package supporting ribs 23.
- the centrifugal material 21 passing through the centrifugal material flows at the ribs 23 in the Rising channels 13 of the plate package 9, where the clear phase to the manifold and the Solids are discharged to the outside.
- the solids are from the Räumansatz 17 taken and promoted by the screw to the conical section 5b.
- the distance of the plate 11 of the plate package 9 is greater than 0.5 mm and less than 3 mm; measured perpendicular to the surface of the plate.
- the angle of inclination the conical plate to the drum axis is preferably between 35 ° and 55 °, especially at 40 ° to 50 °.
- the diameter of the plate 11 at the outer edge is approx. 50 to 75%, in particular 2/3 of the diameter of the free screw area or the drum room.
