1000 Polypropylene High-pressure Diaphragm Chamber Filter Plate

The Type 1000 polypropylene high-pressure diaphragm chamber filter plate is one of the core components for filter presses to achieve efficient solid-liquid separation. The "1000" usually represents the relevant size specifications of the filter plate. This filter plate is manufactured using high-quality polypropylene materials and combined with advanced diaphragm technology, possessing excellent properties such as high pressure resistance and corrosion resistance. It is widely applied in numerous industries that require solid-liquid separation, such as chemical engineering, environmental protection, metallurgy, and mining, providing reliable and efficient solutions for the filtration and dewatering of various complex materials.

Working Principle

Filtration Stage: After the filter press is started, a certain number of Type 1000 polypropylene high-pressure diaphragm chamber filter plates are closely arranged under the action of strong mechanical force, and the inner cavities between the filter plates form a filter chamber. The material to be filtered is conveyed into the filter chamber under the specified feeding pressure. The solid particles in the material are intercepted by the filter cloth and gradually form a filter cake on the surface of the filter plate; while the liquid part passes through the filter cloth, follows the drainage grooves on the surface of the filter plate, and is discharged from the filter chamber through the drainage holes, achieving preliminary solid-liquid separation.

Pressing Stage: After the filtration is completed, high-pressure fluid (such as compressed air or water, etc.) is injected into the space between the diaphragm and the filter plate. The diaphragm expands and bulges under high pressure, squeezing the filter cake in the filter chamber to further squeeze out the water in the filter cake, reducing the moisture content of the filter cake and improving the solid-liquid separation effect. After pressing, the moisture content of the filter cake can be significantly reduced, facilitating subsequent treatment and disposal, such as transportation, landfill, or recycling.

Discharge Stage: After the pressing is completed, the pressure between the filter plates is reduced, and the filter plates are loosened. The filter cake falls off from the surface of the filter plate due to its own gravity or with the help of an auxiliary discharge device (such as a scraper, etc.), completing the discharge process and preparing for the next filtration cycle. The entire discharge process is simple and efficient, allowing the filter plates to be cleaned quickly and improving production efficiency.

Application Fields

Chemical Industry: In the processes of chemical raw material production and chemical product purification, it is used to separate various suspension liquids, emulsions, and other materials, such as in the filtration links of the production of dyes, pigments, pesticides, fertilizers, etc., effectively removing impurities, improving product purity, and ensuring that product quality meets relevant standards and requirements.

Environmental Protection Industry: It is widely applied in fields such as sewage treatment and sludge dewatering. It can efficiently handle solid pollutants in sewage, conduct deep dewatering treatment of sludge, reduce the moisture content of sludge, facilitate subsequent sludge disposal (such as landfill, incineration, etc.), reduce environmental pollution, and contribute to the development of environmental protection undertakings.

Metallurgical Industry: In the processes of metal smelting and ore dressing, it is used to separate the solid particles and liquid in the ore pulp, improve the metal recovery rate, and at the same time treat the tailings to reduce the impact of tailings discharge on the environment, realizing the effective utilization of resources and environmental protection.

Mining Industry: In the processes of ore mining and processing, it filters and dewaters the ore pulp, separates useful minerals and wastewater, realizes the effective utilization of resources and the up-to-standard discharge of wastewater, reduces production costs, and improves economic benefits.
