CERAMIC DISC VACUUM FILTER AND METHOD OF FILTERING SUSPENSIONS Russian patent published in 2019 - IPC B01D33/21 

FIELD: filters.

SUBSTANCE: invention relates to ceramic disc vacuum filters intended for separation of liquid and solid phases of suspension and can be used in ore dressing processes. Disk vacuum filter comprises filtration disk capable of rotating relative to horizontal axis and being partially submerged into bath with suspension. Two knives are located on both sides of filter disc. Filter disc is formed by a plurality of sector elements. Each sector element comprises two ceramic water-permeable side walls, which outer surfaces are located perpendicular to said horizontal axis. Between the side walls there is a cavity designed to create a vacuum therein. Blades are installed so that blades working edges are removed from external surfaces of side walls of sector element located between knives at distance of 1–5 mm. When the control parameter reaches the preset threshold value, back flushing of the side walls may be performed.

EFFECT: technical result is reduced time of filter downtime during sector elements regeneration and service life of sector elements.
