Description

Peeling and discharge device for centrifugal material.

Vertical centrifuges are used as centrifugal devices, especially in the former industry widespread. Their downside compared to the much more expensive horizontal peeler centrifuges is that they go after each The spin process must be stopped and shoveled out by hand. Is it a solvent -or. acidic products, the forces shoveling the centrifuge are particularly at risk. This workflow is time consuming, cumbersome and exhausting. The invention solves the problem of avoiding the disadvantages described

den and without interruption of the centrifuge rotation, as well as without opening. of the lid, peel off the spun off product and convey it to a storage vessel located next to the centrifuge. This is achieved according to the invention in that, particularly in the case of vertical centrifuges a peeling device is mounted permanently installed on the centrifuge housing, its pivotable as well as lowerable The movement of the immersion tube is controlled hydraulically and pneumatically from the outside and a vertical conveyor screw inside takes up, which is driven in the upper part via V-belt drive by a laterally flanged S-motor (13).

, In the lower part closes at a between 5 - 3o inclined screw tube (1), the front end expands against the tube to a Rechteckschäldüse (2) and is equipped with a vertical (3) and r horizontal (k) peeling knife which for the purpose of peeling first in the upper part of the centrifuge drum by radial rotation of the immersion tube with the vertical paring knife (3) to the end position in front of the drum wall and then moved vertically down to the end position over the drum base. When the drum base is reached, the peeling cycle is ended, so that the peeling nozzle (2) is guided in the same way up the drum wall and from there back to the center of the drum. The horizontally inclined screw, which becomes larger conically at the peeling nozzle, is driven by the vertical screw via a bevel gear set and conveys the product peeled off by the peeling nozzle in the centrifuge space over a pressing section (7) »which simultaneously serves as a gas-tight seal between the centrifuge interior and the operating space, the Vertical screw (11), which conveys the product upwards and ejects it laterally via a downpipe (15). The features of the invention and the execution are described in more detail on the exemplary embodiment illustrated by the drawings.

the airtight protective housing (1 * 0, which surrounds the mechanics; the lall tube (15), which can be replaced by a further horizontal screw when loading pasty products.

! ■■ ig. 2 - shows the hydraulic cylinders, hadial cylinders (9) and axial cylinders (1o), which by means of a specially developed hydraulic unit, pneumatically controlled, move the peeling nozzle within the centrifugal drum - swiveling in - lowering - raising, swiveling back to the center of the drum. The forces occurring during the peeling process are transmitted by the square rod (16) on the side of the immersion tube to the housing (1'O) surrounding the immersion tube. The gear wheel (17) located in the middle part of the apparatus serves both to carry out the pivoting process and to store the immersion tube (6), as well as to accommodate the axial hydraulic cylinder (1o) located parallel to the immersion tube, which executes the pivoting movement of the immersion tube in the same way and whose piston rod eye sits on a bolt (18) welded to the side of the immersion tube by means of maintenance-free spherical bearings and thus transmits the axial movement.

Claims (1)

Patent claims: 1.) Peeling and discharge device for centrifugal material from rotating Centrifuges characterized in that in the bit of the centrifuge airtightly connected device calibrated in the Zentrifugentromir.el both pivotable and lowerable immersion tube (8) is located, the movements of which are controlled hydraulically and pneumatically from the outside and that inside only promoting the ine assigned product has a vertical screw (11) that carries the product upwards from the Centrifuge challenges and via a downpipe (15) into an adjacent one Discards the storage container and at its lower end calibrate a screw conveyor (5) inclined to the horizontal, which is connected by the vertical screw (11) is driven via bevel gears (6) and its screw tube (1) becomes a rectangular peeling nozzle at the end (2) with vertical (3) and horizontal (OSchälaesser expands and this initially for the purposes of peeling off in the upper part the centrifuge drum by turning the immersion tube (8), among other things, the tube 009884/0176 19.1.7ο . k. _ Claims moved axially to the end position of its vertical peeling edge (3) before the Tromraelwand then in the vertical direction to the end position of the horizontal peeling edge ⁽¹ O after shifted down is, and is then returned after the completion of the peeling operation in the same way back to the starting position · 2.) Device according to claim 1, characterized in that the Product upwardly ejecting vertical screw (11) via a pressing section (7) from the centrifuge interior to the outside one pen inclined to the horizontal, in the area of the peeling nozzle (2) conically widening screw (5) is charged, the t conical end of which increase the otherwise usual degree of filling and thus the removal time of the product will be shortened 3 ·) Device according to claim 1 characterized «that the Immersion tube (8) is surrounded by a housing (1 * f) that supports the Immersion tube (8) gas-tight during movement in the interior of the centrifuge seals and guides without play k.)
