CARTRIDGE-TYPE FILTER Russian patent published in 2012 - IPC C13B20/16 B01D27/00 

FIELD: filtering.

SUBSTANCE: invention refers to the method of I and II carbonation juice filtering, syrup filtering in sugar refining industry, more specifically, to cartridge-type filters designed for fluid clarification from mechanical admixtures. The cartridge-type filter includes a vertical cylindrical body with a conical lower part and a cover, filter cartridges installed upright in parallel rows inside the body and attached in cantilever fashion by their upper part to manifolds placed under the cover, having ellipse-shaped central parts in the cross-section area and peripheral parts radially located against cartridge vertical axis, and filtering cloth fastened on the outside of the cartridges. The manifolds are attached to filter cake discharge tubes which are connected to the compressed air receiver fixed on the body. The body is equipped with fluid inlet, decompression and cake discharge arms, pressure device for cartridge vertical fixation located in the upper part of the body, which contains cross bars horizontally and transversely located against filter cartridge rows. Radial peripheral parts of each filter cartridge form converging channels. The cartridge surface is inward bent in the area between the central and peripheral parts, and the filtering cloth is fixed on the cartridge surface being movable against outside surface of the said parts for its clearing from cake. The surface of the filter cartridge radial peripheral parts should be made wave-like.

EFFECT: filter performance increase, filtering cloth clearing efficiency improving, reducing filter cartridge vibration with compressed air impulse inlet and increase of device filtration unit area.
