CERAMIC FILTERING ELEMENT OF DISC VACUUM FILTER AND ITS FIXING UNIT Russian patent published in 2021 - IPC B01D33/23 F16B1/00 

FIELD: filtering devices.

SUBSTANCE: invention can be used to separate liquid and solid phases of a suspension using ceramic filtering elements. A fixing unit of ceramic filtering element 100 contains mounting sleeve 110 with central hole 111, two flange elements 120 and 130 connected to mounting sleeve 110 at its ends, and inner sleeve 140. Mounting sleeve 110 has main section 112, designed to be placed in mounting hole 9, and connecting section 113. Flange elements 120, 130 have through central holes 121, 131, inner contact surfaces 122, 132 and outer contact surfaces 123, 133. Inner contact surface 122 faces inner contact surface 132 of another flange element, and it is designed to come into contact with side surfaces 2 and 3 of the ceramic filtering element. Outer contact surfaces 123 and 133 are designed to come into contact with pressure washers. Central holes 121 and 131 of flange elements 120 and 130 and central hole 111 of mounting sleeve 110 form a single central hole, throughout which, inner sleeve 140 is located. Mounting sleeve 110 and both flange elements 120, 130 are made of polymer material, and inner sleeve 140 is made of metal. A ceramic filtering element of a vacuum disk filter is also proposed.

EFFECT: ensuring an optimal balance of stiffness and elasticity of the mounting joint.
