Diaphragm filter presses are high-efficiency solid-liquid separation equipment that achieve material dehydration through the principle of pressure filtration. Their core structure consists of diaphragm filter plates, frames, and hydraulic systems. During operation, high pressure (such as 12 MPa) is applied to squeeze the material between the filter plates, allowing the liquid to pass through the filter cloth and exit, while the solid is retained to form a filter cake.

‌Features & Advantages‌

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

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

3. Energy-efficient & High-performance: The diaphragm secondary extrusion technology can reduce the moisture content of filter cake to below 15%, significantly cutting down on drying costs.

4.‌Wide Application‌: Suitable for industries such as oil, water treatment, dyeing, etc., 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 inflated secondary pressure to 1.2-1.5 MPa, lasting 10-15 minutes.

3. Discharge Stage: Automatically open the filter plate, cake falls off (Note: Operation must be done after the machine is stopped and pressure is released to avoid high-pressure risks).

‌Caution Notice‌

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 essential in low-temperature winter conditions. We currently have such products in stock, offering fully automatic container membrane filter presses for precise filtration and efficient dewatering. Suitable for the oil and water treatment industries, these presses operate at a working pressure of up to 12MPa. Please contact us for a tailored solution.
