Diaphragm press filter is an efficient solid-liquid separation equipment that achieves material dehydration through the principle of pressure filtration. Its core structure consists of diaphragm filter plates, a frame, and a hydraulic system. During operation, it uses high pressure (such as 12MPa) to squeeze the material between the filter plates, allowing the liquid to pass through the filter cloth and be discharged, while the solid is retained to form a filter cake.

Features and Advantages:

1. Precision Filtration: Utilizes activated carbon and other filter media to process low-corrosive, low-temperature materials (such as lubricating oil) with high filtration accuracy.

2. Full Automatic Operation: Equipped with PLC control system for automatic clamping, unloading, and cleaning.

3. Energy-saving and Efficient: Diaphragm secondary squeezing technology can reduce the moisture content of the filter cake to below 15%, significantly reducing drying costs.

4.‌Wide Application: Suitable for industries such as oil, water treatment, and dye, with an effective filtration area of up to 250㎡.

‌Operation Process‌

1. Feed Stage: Material is pumped into the filter chamber, with a recommended pressure control of 0.6-0.8 MPa.

2. Pressing Stage: Diaphragm inflation secondary pressure to 1.2-1.5 MPa, for 10-15 minutes.

3. Discharging Phase: Automatically pull open the filter plate, cake falls off (Note: Perform after stopping the machine and releasing pressure to avoid high-pressure risks).

‌Important Notes:‌

Regularly inspect filter cloth for damage to prevent material leakage.

Corrosive materials require the use of PP or rubber diaphragms.

Insulation and anti-freezing are necessary in low-temperature winter conditions. We currently have such products in stock, offering fully automatic membrane press filters for precise filtration and efficient dewatering, suitable for the oil and water treatment industries. Operating pressure up to 12 MPa. Please contact us for a solution.
