FILTERING APPARATUS Russian patent published in 1997 - IPC

FIELD: filtering liquid media through semi-permeable diaphragms. SUBSTANCE: filtering apparatus has bearing plates with manifolds for supply of separable liquid and discharge of filtrate and condensate and skeleton plates made in form of frames in whose inner cavities drain devices are arranged. Frames are provided with holes for supply of separable liquid and discharge of filtrate and additional holes for communication of their opposite sides. Grooves located on two sides of frame are used for connection of separable liquid supply holes and filtrate discharge holes with additional holes which are brought in communication with inner cavities of frames. Additional holes are located between separable liquid supply holes and filtrate discharge holes and inner edge of frame bounding its inner cavity. Grooves connecting the separable mixture supply holes and filtrate discharge holes with additional holes are located on one side of frames and grooves connecting the additional holes with inner cavity of frames are located on other side of frames. EFFECT: enhanced efficiency. 4 cl, 3 dwg
