Van filter Van filter supply works composed by the filter plates arranged filter chamber (both sides recessed filter plate, each combination of two filter plate into a car-shaped filter chamber) illustrating the principles as follows: Plates of surface pitting and bosses for supporting the filter cloth have through holes on the filter plate in the center and corners, assembled to form a complete channel, can pass into the suspension, washed with water and leads to a filtrate. Plates on each side A handle support bracket on the beam, pressed by the pressing means the filter plate. cloth acts as a seal between the filter plate. In conveying the pump pressure, the material feeding the liquid to be filtered each filter chamber, through filter media (depending on the industry to select the appropriate filter cloth), the solid and liquid separation. form a residue on the cloth, until the formation of the filter chamber filled cake. The filtrate through the filter cloth and filter plate grooves along the fluid flow to the bottom of the hole channel, concentrate discharged by filtration is completed, the washing water can pass into the filter residue was washed clean. After washing, sometimes pass into the air, to remove residual washing solution. After filtration removing filter cake was opened (cake stored in that phase between two adjacent filter plate), cleaning cloth and re-pressing plate filter to begin the next work cycle. Shanghai Van filter large sheet work a flat filter plate and a hollow plate and frame filter when the filter chamber principle frame composition, cloth fixed on the frame, which is an early form of the main filter, the main advantages are easy to replace Van filter cloth, the disadvantage is inefficient, ineffective filtration, filtration plate easily broken; Van filter The filter chamber is made up of two adjacent recessed filter plate configuration, cloth fixed on each filter plate, the main advantage is the high efficiency filter press van, better, Plates relatively durable (under the same conditions), the disadvantage is the replacement of cloth a little trouble, but now have a high degree of automation, cleaning cloth also has an automatic device, the number of general replacement of the filter cloth is not frequent.
