LIQUID FILTRATION UNIT Russian patent published in 2009 - IPC B01D33/00 

FIELD: treatment facilities.

SUBSTANCE: invention relates to liquid filtration units with filtering cloth which are mounted at a conveyor operated by a controllable gear motor. The liquid filtration unit comprises a filter casing with a filtration chamber in the upper part and a tank for the purified liquid - in the lower part. Horizontal pipes with holes in their bottoms through which the liquid is supplied for treatment are placed above the filtration chamber. The filtration chamber comprises a belt conveyor meant for the filtering cloth holding. The feature of novelty consists in the fact that the conveyor is made up of one middle conveyor belt and two side conveyor belts set on both sides of the middle one and each belt is tightened on its own shafts forming three close loops. The middle conveyor belt is embracing at least 4 parallel shafts with the middle shafts being set lower than the outside ones thus a raise of the middle conveyor belt on the outside shafts is provided. The side conveyor belts are inclined to the middle belt thus forming a trough-like pot.

EFFECT: invention provides for fast fine qualitative purification of large lubricating coolant amounts.
