CERAMIC FILTER FOR PURIFICATION OF LIQUIDS, A METHOD OF ITS PRODUCTION AND A DEVICE FOR FORMATION OF A CERAMIC FILTER Russian patent published in 2005 - IPC

FIELD: purification of polluted liquids.

SUBSTANCE: the invention is dealt with purification of polluted liquids , in particular, with a ceramic filter for purification of polluted liquids. The ceramic filter contains at least one plate of the rectangular form made out of a porous oxide material with through channels, on the walls of which a membranous layer out of a source material is formed, and connectors between the channels. A maximum size of a channel cross-section, a plane thickness, a connection thickness and its width are in a definite dependence to each other. The mentioned filter is produced in the device for formation, which is supplied with a preheated receiving unit and a storage unit, a means for channels formation in the plate body by a method providing for a stirring of a ceramic material of different composition in parallel in the heated and not heated mixers, commixing of blends from the mixers, filling the device for formation with the produced mixture. A formed ceramic plate is directed into the preheated receiving unit, cut out a piece by a piece as the preheated receiving unit is filled and then directed to the storage unit. After extraction from the storage unit a plate is cut for measuring pieces and subjected to burning at the temperature of 1200-1550°C. The technical result is simplification of the method and the device at production of plates of big size with the thin walls of channels.

EFFECT: the invention ensures simplification of the method and the device at production of plates of big size with the thin walls of channels.
