Explanation of the reasons for the fast and slow filtration cycle of sludge filter presses

1、Selection of filter cloth

　　As a kind of filtering medium, the filter cloth of sludge filter press is suitable for different materials with different meshes. Though the denser the mesh of the filter cloth, the higher the precision of filtration, the slower the relative filtration speed. Different industries, the requirements of the filtrate are not the same, according to their own needs to choose the right filter cloth, so the selection of filter cloth is very important.

2, the size of the granularity of the material

　　The granularity content of the feed slurry is about high, the surface area of the material is relatively large, the feed pump conveying flow is relatively lower, the filtration speed will be correspondingly reduced down.

3, the material concentration of high and low

　　The flow rate of the feed pump refers to the flow rate of the water, so the greater the concentration of the material, the greater the impact on the feed pump, the flow rate slows down, reducing the speed of filtration. The alternating filter plates and frames of the chamber filter press form a group of filter chambers. The surface of the filter plate has grooves, and its protruding parts are used to support the filter cloth. There are holes on the corners of the filter frame and filter plate, which constitute a complete channel after assembly, and can pass into the suspension, washing water and lead out the filtrate.

4、Whether the material is sticky

     If the material is sticky, the separation of solid material and liquid material is relatively poor, and the fluidity of the material is poor, which also affects the filtration speed. Sludge filter press alternately arranged filter plate and frame constitute a group of filter chamber. The surface of the filter plate has grooves, and its protruding parts are used to support the filter cloth. There are holes on the corners of the filter frame and filter plate, which constitute a complete channel after assembly, and can pass into the suspension, washing water and lead out the filtrate.

5、Choice of feeding pump

　　The filtration power of sludge filter press comes from the feed pump, the filter press utilizes a special filter medium, exerts pressure on the object, makes the liquid dialysis out of a kind of mechanical equipment, is a kind of commonly used solid-liquid separation equipment. It is a commonly used solid-liquid separation equipment. It is widely used in chemical, pharmaceutical, metallurgy, dyestuff, food, brewing, ceramics and environmental protection industries. Because, the size of the feed pump flow, the size of the head directly affects the chamber filter press filtration cycle.
