Description

Das Zentrifugalfilter (Figur 1) besteht aus einem zylindrischen Behälter 9 mit flachem Deckel 10 und einem konischen Boden 11, einem tangentialen Einlauf 1, einem radialen Auslauf 2 und Gi-'; nem Feststoff abzug 3.The centrifugal filter (Figure 1) consists of a cylindrical container 9 with a flat lid 10 and a conical bottom 11, a tangential inlet 1, a radial outlet 2 and a solids outlet 3.

'; Im oberen Teil des Behälters, fest verbunden mit dem in diesem , Bereich axialen Auslaufrohr 2a ist ein zylindrischer Siehkör-'■;". per 5 angeordnet.'; In the upper part of the container, firmly connected to the outlet pipe 2a which is axial in this area, a cylindrical screening body 5 is arranged.

'., Im Bereich des konischen Bodens 11 befindet sich ein Rühr- und f| Räumwerk 8. Die Rohrwelle 12 des Rühr- und Räumwerkes 8 dient If im oberen Teil auch der Spülwasserzufuhr zu der sich innerhalb %, des Siebkörpers drehenden, hydraulischen Siebreinigung 6. (Figur 3) Ebenso ist an der sich drehende Rohrwelle 12 auch der i mechanische Abstreifer 7 (Figur 3) befestigt. '., In the area of the conical bottom 11 there is a stirring and clearing device 8. The tubular shaft 12 of the stirring and clearing device 8 also serves in the upper part to supply flushing water to the hydraulic screen cleaning device 6 rotating within the screen body. (Figure 3) The mechanical scraper 7 (Figure 3) is also attached to the rotating tubular shaft 12.

Die Rohrwelle 12 tritt durch den Siebkörper 5, das axiale Auslaufrohr 2a und dessen Deckel nach außen und ist dort mit dem Rühr- und Räumwerksantrieb 13 verbunden. Die Rohrwelle 12 ist durch das Getriebe des Antriebs 13 durchgesteckt und hat am oberen Ende ein Drehgelenk für den Spülwasseranschluß 4.The tubular shaft 12 passes through the sieve body 5, the axial outlet pipe 2a and its cover to the outside and is connected there to the agitator and auger drive 13. The tubular shaft 12 is passed through the gear of the drive 13 and has a swivel joint at the upper end for the flushing water connection 4.

I)It

Centrifugal filter for separating solids from liquids.

The equipment currently in use, such as hydrocyclones, slotted screens or similar devices, can only accomplish part of the task assigned to them due to the different physical properties of the material to be separated, while the device according to the invention ensures optimal function under all operating conditions through the combination of screening, centrifugal separation, sedimentation and thickening. In addition, unlike conventional separators, the combination of mechanical and hydraulic cleaning of the separation device results in a significantly reduced susceptibility to failure, reduced maintenance effort and greatly reduced abrasion of the screen body. In contrast to the devices previously described, the stirring and clearing mechanism located in the solids collection chamber not only optimally thickens the material, but also prevents blockages in the solids discharge.

The purpose of the invention specified in claim 1 is the removal of solids, in particular sedimenting solids, which cause disturbances in the system, from the liquid phase without the hydraulic circuit having to be interrupted or opened, while at the same time optimally concentrating the separated solids, whereby the susceptibility to disturbances and the maintenance effort of the apparatus are greatly reduced by the essential design features.

An embodiment of the invention is explained with reference to Figures 1 to 3.
