A filter press plate is a component of a filter press machine used in solid-liquid separation processes. Filter plates are typically made of a variety of materials, such as polypropylene, stainless steel, cast iron, or aluminum. They come in different shapes and sizes depending on the application and filtration requirements. The filter plates are mainly divided into plate and frame filter plate, chamber filter plate, membrane filter plate, stainless steel filter plate, cast iron filter plate, gasket filter plate, and round filter plate, etc.
The filter plate is a key device in the water treatment process, and it plays the dual role of carrying the filter layer for filtration and backwashing water distribution in the filter tank. The quality of the filter plate is directly related to the long-term benefits of the filtered water quality, water quantity, and operation of the water plant and sewage plant.
Stainless Steel Filter Plate
The stainless steel filter plate is the main part of the filter, mainly used to filter activated carbon, diatomaceous earth, white clay, etc. The stainless steel filter plate is composed of five layers of screens, the middle one is a screen with a larger hole diameter and a thick wire diameter as a support, and then there are two layers of finer screens placed on both sides of the support screen, and the outermost layer is the core. The filter screen plays the main role of filtering. The whole is rolled and formed by stainless steel plate, and the five-layer filter screen is fixed by rivets.

Filter cake
1. The stainless steel filter plate and the outer edge of the stainless steel wire mesh are integrally welded together. When the filter plate is reversely flushed, the wire mesh and the edge of the plate are welded firmly by hand. The outer edge of the filter plate will not be torn or damaged, ensuring the quality of the filtered liquid without frequent replacement.
2. The stainless steel filter plate and stainless steel wire mesh have high strength and are not affected by backwashing strength.
3. Stainless steel wire mesh is not easy to stick to impurities and not easy to clog. After filtering liquid, especially the pre-coated diatomite layer, it is easier to wash and is more suitable for high-viscosity and high-strength liquid filtration.
4. The upper opening surface is made of stainless steel wire mesh with uniform gaps, and the lower closing surface is made of stainless steel plate. It ensures that the liquid does not leak, with upper opening and lower closing and high strength.
5. It is suitable for air and water mixed flushing. After backwashing, the filter plate recovers its performance.
6. Anti-backwash pressure 0.6-0.8Mpa.
1. Catalyst filtration and separation;
2. Filtration of high-temperature gas in petrochemical industry, filtration of exhaust gas in petrochemical plants, filtration of catalytic cracking oil slurry;
3. Purification of high-temperature flue gas in the metallurgical industry;
4. Filtration of other high-temperature gases and liquids;
5. Filtration of various high-temperature, corrosive liquids and catalysts in the petrochemical industry;
6. Filtration and purification of various polymer melts in the chemical fiber film industry;
7. Filtration and separation of various catalysts in the pharmaceutical industry;
8. For gas distribution, orifice plate material for liquidized bed;
9. Used for high-pressure backwashing oil filters, etc.;
10. Used to filter various slurries of edible oil, beverage, and food;
11. Used to purify and filter production sewage.
Installation requirements
The horizontal installation accuracy of the filter plate is relatively high, and its important basis is the leveling of the whole pool of the filter beam and the positioning accuracy of the stainless steel parts used for the pre-embedded riveted filter plate. Therefore, the leveling of the filter beam requires a horizontal line and must have a high standard. Only metal molds and skilled manufacturing techniques can ensure the flatness of the filter beam. After the plane is leveled, the filter plate can be installed.
1. The construction shall be carried out according to the requirements of the design drawings, the horizontal error of a single pool plate surface shall not be greater than 2mm, and the elevation error of each filter tank shall not be greater than 5mm;
2. The joints of the filter plates are required to be air-tight, water-tight, and able to withstand the pressure of flushing;
3. Before the filter plate is laid, use a level to detect that the error of the elevation value of the supporting beam surface is less than 2mm;
4. The joints of the filter plates are embedded and filled with 903 polymer cement mortar, and the joints are cured in a humid environment for three days and put into use after seven days;
5. During the construction, it should be noted that the mortar cannot leak into the pool or seal the filter head. After installation, the mortar on the surface of the filter plate should be cleaned.
