DEVICE FOR THIN-LAYER PURIFICATION OF LIQUIDS Russian patent published in 2014 - IPC B01D21/02 

FIELD: chemistry.

SUBSTANCE: device contains a tank, equipped with branch pipes. Axles are placed in an upper part of the tank. Vertical plates are fastened on the axles with a possibility of reciprocal movement. Inclined lamellas are placed on both sides of the vertical plates. Between each two plates a level of fastening lamellas on one plate is displaced with respect to the level of the fastening lamellas on an adjacent plate in such a way that lower edges of the lamellas alternate with each other and are geometrically placed with the minimal clearance on the vertical. To provide reciprocal movement of the lamellas the axles are made with eccentric necks and are connected to a pneumatic drive with a possibility of periodical connection, which can be realised in a manual mode or automatically. The tank is equipped with the branch pipes for supply of liquid to be purified and output of the pure liquid, as well as with additional branch pipes for the supply of a washing liquid and output of sludge.

EFFECT: reduction of the device outer dimensions with the preservation of productivity, reduction of metal consumption and labour consumption for the device production with the preservation of high quality of liquid purification.
