Plate and frame filter press
First, the device overview
Plate and frame filter press works the plate and frame filter chamber having a flat filter plate and frame filter composed of a hollow, cloth fixed on the frame, which is an early form of the main filter, Van filter the main advantage is easy to replace the filter cloth, the disadvantage is inefficient, ineffective filtration, filtration plate easily broken; van filter filter chamber is made up of two adjacent recessed filter plate constituted.

Third, the principle
Pitting the surface of the filter plate and the boss for supporting the filter cloth. There on the corner and the center of the filter plate through hole, assembled to form a complete path, can pass through the suspension, washed with water and extraction filtrate. Plates on both sides of each handle support bracket on the beam by pressing means pressing filter plate. Cloth filter plate between the sealed role.
In conveying the pump pressure, the material needs to be filtered liquid feed each filter chamber, through the filter media (according to different industries to choose the right cloth), the solid and liquid separation. Form a residue on the cloth, until the formation of the filter chamber filled cake. The filtrate passes through the filter cloth and filter plate trench along the bottom of the liquid flow to the cell passages, concentrated discharge. Filtration is complete, the residue was washed through the washing water into the clear. After washing, sometimes pass into the air, the remaining washing liquid is removed. After removing the filter open filter cake (cake store lies between two adjacent filter plates), cleaning cloth and re-pressing filter plate to begin the next work cycle.
Cloth fixed to the frame, which is an early form of the main filter press, chamber filter press of the main advantages is easy to replace the filter cloth, the disadvantage is inefficient, ineffective filtration, filtration plate easily broken; van pressure filter chamber filter press is composed of two adjacent recessed filter plate configuration, cloth fixed on each filter plate, the main advantages of chamber filter press is more efficient, better, the filter plate is relatively durable (under the same conditions), but have a high degree of automation, cleaning cloth also has automatic device, the number of ships will not replace the cloth frequently.
