How to extend the service life of chamber filter press by improving filter plate and filter cloth materials?

In terms of extending the service life of chamber filter press, the improvement of filter plate and filter cloth is undoubtedly the key. As a professional manufacturer, we are well aware of the importance of the selection and improvement of filter plate and filter cloth to the overall performance and durability of the equipment. The filter plate is one of the core components of the chamber filter press, and the choice of its material directly affects the equipment's pressure resistance, corrosion resistance and stability during long-term operation. Traditional filter plate materials, such as ordinary polypropylene or metal materials, often deform, crack or corrode when facing high pressure and highly corrosive working conditions, which not only affects the filtering effect, but also leads to frequent shutdown and maintenance of the equipment.

To this end, our company has developed a variety of high-performance filter plate materials, such as reinforced polypropylene filter plates and composite rubber filter plates, for different working conditions. The reinforced polypropylene filter plate greatly improves its tensile strength and corrosion resistance while maintaining its lightweight by adding alkali-free glass fiber or other reinforcing agents. This filter plate can not only maintain a stable shape under high pressure, but also effectively resist the erosion of acidic and alkaline substances, and is suitable for harsh environments such as chemical industry and metallurgy. In addition, we have independently developed a composite rubber filter plate, which further enhances the pressure resistance and durability of the filter plate by combining chloroprene rubber with a high-strength steel frame. This filter plate can not only withstand high working pressure, but also maintain good working conditions in high temperature and high humidity environments, greatly extending the overall service life of the equipment.

In terms of filter cloth, we have also upgraded the technology. As the direct contact surface between the filter plate and the material, the material and weaving method of the filter cloth are crucial to the filtering effect and the protection of the filter plate. After long-term use, traditional filter cloth is prone to wear, clogging or chemical corrosion, which affects the filtering effect and accelerates the wear of the filter plate. In order to extend the service life of the filter cloth, we introduced high-strength fiber materials and adopted more advanced weaving technology, so that the filter cloth can still maintain good water permeability and strength under high-pressure filtration. At the same time, we have also developed corrosion-resistant filter cloth specifically for high-corrosion environments. This filter cloth can maintain stable physical properties for a long time when facing strong acid and strong alkali materials, reduce the frequency of replacement, and thus reduce the operating cost of the equipment.

In order to further improve the durability of the filter cloth, we have also designed an automatic cleaning function for the filter cloth. This function uses high-pressure water flow to regularly flush the filter cloth to prevent the accumulation and clogging of materials on the filter cloth. It can not only maintain the water permeability of the filter cloth, but also effectively extend its service life. The introduction of the automatic cleaning system also reduces the frequency of manual intervention, improves the degree of automation of the equipment, and thus improves the overall production efficiency.

The company has obtained a number of national patents in terms of material improvement of filter plates and filter cloths with many years of R&D experience. These technologies have been widely recognized by domestic and foreign customers. Through continuous innovation and technological upgrading, we can not only meet the current needs of customers, but also cope with higher challenges that may arise in the future. As a manufacturer with rich experience and technical strength, we will continue to be committed to providing customers with better quality and more durable filtration equipment to meet the needs of solid-liquid separation under various complex working conditions.
