The filter press uses the pressure difference on both sides of the filter cloth to force the absolute majority of the water in the material to pass through the filter cloth and flow out of the body, while the material is blocked in the filter chamber to form a filter cake to achieve the purpose of filtration. Since there is a large pressure difference on both sides of the filter cloth during the filtration process, the filtration effect is much better than that of a vacuum filter. The filter press still has a good effect even when dealing with difficult-to-filter materials, and is easy to use as an anti-corrosion treatment. It has a simple structure, is easy to operate, and is cheaper than other filters. Therefore, choosing a filter press as a dehydration equipment is your best choice. At present, filter presses have been widely used in industries such as chemical, pharmaceutical, metallurgy, ceramics, sugar, pigments, dyes, cement, silicates, and municipal and industrial sludge dehydration.

The filter plates of the filter press produced by our company are made of reinforced polypropylene by one-time molding, and are equipped with a corrosion-resistant and strong frame with stable performance. The whole machine has beautiful appearance, economical and practical, and has the following advantages: The convex cylindrical point filter plate used to be a straight strip or horizontal strip water flow trough, and its actual water conduction area was 50%. The convex dot filter surface adopted by our company not only increases the effective water conduction area, but also allows the filtrate to flow in any direction, thereby shortening the process and increasing the filtration speed. The feed port is in the middle of the filter plate, with a large aperture, small resistance and uniform force on all parts, which is suitable for various difficult-to-filter materials. What makes users feel very convenient is that the three-piece jacket is designed without a filter cloth locker, but directly sewed, and the filter cloth is sewn together, which is convenient, economical and durable. The filter plate is made of reinforced polypropylene material, which has the characteristics of stable chemical properties, corrosion resistance, acid resistance, alkali resistance, salt resistance, non-toxic and tasteless, light weight, high strength, good toughness, and low labor intensity of unloading operation. The frame design is reasonable, smart and practical. During the operation, the combined action design of hydraulic and electrical in the forward and backward strokes is adopted, which greatly reduces the labor intensity. The electric contact pressure gauge is used to achieve automatic pressure maintenance. It has the advantages of convenient operation, stable operation, and reliable structure. The diaphragm filter plate is used. After the filtration is completed, air can be introduced into the diaphragm cavity to squeeze the filter cake, so that the filter cake is dehydrated more fully and the moisture content of the filter cake is reduced. It is particularly suitable for filtering materials with high requirements for the moisture content of the filter cake and difficult to dehydrate. It can improve production efficiency. According to user needs, our company can also produce automatic plate-pulling filter presses, which saves the trouble of manually pulling the plate to unload the material. It really saves time and effort. Before working, put the filter cloth on the filter plate, then operate the filter press, drive the clamping rod, and press the clamping plate tightly against the filter plate. Start the feed pump to input the material into the filter press through the feed port, and the material enters the filter chamber through the channel on the filter plate. Under the action of the feed pump pressure, the clear liquid passes through the filter cloth and enters the densely distributed dot-shaped filter surface on the filter plate. Then it flows out from the liquid outlet after being collected through the channel on the filter plate. The filter cake is retained in the filter chamber until the filter cake fills the filter chamber, then stop the feed pump, loosen the clamping plate, and then pull the filter plates one by one towards the clamping plate to remove the filter cake in the frame, and then re-enter the next working cycle.
