Embodiment Construction

[0042] exist figure 1 In the schematic diagram of , a centrifuge, for example a sugar centrifuge, with a centrifuge drum 10 can be seen in vertical mid-section. The centrifuge bowl 10 has a drive shaft 11 which also forms the vertically arranged axis of the centrifuge bowl 10 and provides a rotational drive for the entire centrifuge bowl 10 . exist figure 1 The drive shaft 11 is only indicated schematically. The direction of rotation 12 is additionally marked by an arrow.

[0043] The centrifuge bowl 10 also has a housing 13 which is set in rotational motion by a rotary drive 11 . The housing 13 is substantially cylindrical and is covered on its inner wall by a working screen, not described in detail.

[0044] Thick liquor, in particular with sugar crystals still with the mother liquor, is sent to the centrifuge bowl 10 . The thick liquid is centrifuged by the centrifuge drum 10 driven at high speed, wherein the sugar crystals do not permeate through the working sieve, bu...

Abstract

The invention relates to a discontinuous centrifuge. The discontinuous centrifuge comprises a rotatable centrifuge drum (10) that includes a driving spindle (11), a jacket (13) and a bottom (15). A hub (30) of the centrifuge drum (10) has multiple arms (31) for indirectly or directly connecting the jacket (13) of the centrifuge drum (10) to the driving spindle (11) of the centrifuge drum (10). A scraper (20) is used for scraping a product (14) off the inner wall of the jacket (13) of the rotatable centrifuge drum (10). The scraper (20) includes an element (22) that can pivot about an axis running parallel to the axis of rotation of the centrifuge drum (10). Said element (22) has a blade which extends along nearly the entire height of the centrifuge drum (10) and is in contact with the product (14) after pivoting. The scraper (20) is designed to be immobile in the vertical direction. The arms (31) of the hub (30) have top surfaces (32) that lie below the bottom (15) of the drum. The scraper (20) is mounted separately from the centrifuge drum (10), which is mounted in an oscillating manner.

Description

technical field [0001] The invention relates to a batch type centrifuge, comprising: a rotatable centrifuge drum having a drive shaft, a housing and a bottom; A plurality of arms connected indirectly or directly to the drive shaft of a centrifuge bowl; a scraper for removing product from the inner wall of a rotatable centrifuge bowl at a scraping rate of rotation Upper scraping, wherein the scraper has an element rotatable about an axis parallel to the axis of rotation of the centrifuge bowl, wherein the element has a blade extending over almost the entire length of the centrifuge bowl Extended in height and in contact with the product after turning. Background technique [0002] Batch centrifuges are also used in particular to separate sugar crystals from sugar crystal suspensions. [0003] The raw material, for example a thick liquid with accumulated crystal suspension, is supplied from above and is then processed in the centrifuge bowl so that the product, here crystals...
