Rubber filter machine The filter plate is the primary filtration component of a plate-and-frame filter press—the heart of the machine. Through meticulous design by our factory in collaboration with the Jiangsu Institute of Chemical Research, it is manufactured using advanced processes and formulations, boasting a rational structure, high strength, rapid filtration rates, versatile functionality, excellent resistance to corrosion, superior sealing performance, and an extended service life.

(1) The holes in the filter plate are designed to be both rational and flexible, with the feed port positioned at the center‑top of the plate, facilitating radial flow in all directions. During operation, the filter plate remains deformation‑free, ensuring high throughput and rapid filtration. The filtered cake exhibits low moisture content, and when the filter plate is lifted, the filter cartridge automatically disengages from the filter cloth under its own weight, without any external force.

(2) The filter plate’s filtration surface features a textured, dimpled structure. During high-pressure filtration, the filter is not directionally constrained; fluid flows radially along the channels formed by the dimples, reducing flow time and significantly increasing filtration speed.

(3) The filter plate frame is fabricated by welding reinforced full‑steel plates and round steel bars, with a thickness of 12 mm. After undergoing spray rust removal, acid pickling, rinsing, preheating, and coating with APLK adhesive, it exhibits high hardness (SARL 80–85), superior overall quality, excellent sealing performance, and outstanding durability.

Rubber filter press What is the hydraulic system like?

This hydraulic station features a vertical configuration. Its hydraulic system performs both the pressing action of the cylinder and automatic cylinder recharging, enhancing the overall safety and reliability of the system while simplifying maintenance for users. Key components of the rubber filter press’s hydraulic station include cylinders sourced from the Sino‑German joint‑venture Wuxi Hydraulic Components Factory, with check valves, directional control valves, relief valves, and other hydraulic parts supplied by Taiwan’s Huadu Hydraulic Components Factory and Shanghai’s Huadu Hydraulic Components Factory. These high‑quality components ensure greater safety and stability, enabling the system to smoothly carry out the user’s entire filtration process.

Hydraulic system: It consists of three main components—power unit, control system, and actuating elements. The control system includes a high-pressure relief valve, pressure gauge, check valve, solenoid directional valve, hydraulically controlled check valve, low-pressure relief valve, and an electrical contact pressure gauge. Cylinder pressure is regulated by the high-pressure relief valve, while platen pressure is adjusted by the low-pressure relief valve. The compression system is governed by the hydraulically controlled check valve, and the solenoid directional valve is used to tighten the cylinder, thereby enabling two fundamental operations. An electrical contact pressure gauge provides automatic compensation for the rear chamber (high-pressure chamber) pressure of the cylinder, maintaining pressure within a specified range and ensuring the filtration process proceeds smoothly.

The electrical control system of the rubber filter press—comprising both relay‑based circuitry and PLC‑programmed logic—delivers reliable, safe, and stable performance. The PLC program employs Mitsubishi PLC control modules and low‑voltage components from Sweden’s ABB, ensuring a user‑friendly human–machine interface that is simple and intuitive to operate.

PLCs are compact, powerful, fast, highly stable, and highly flexible and scalable. They allow control programs to be modified according to process requirements and can be conveniently operated via a computer interface, enabling remote control.
