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 filter media to handle weakly corrosive, low-temperature materials (such as lubricating oils) with high filtration accuracy.
2. Full Automatic Operation: Equipped with PLC control system for automatic clamping, unloading, and cleaning.
3. Energy-efficient & High-performance: Diaphragm secondary compaction 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, dye, 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 of 0.6-0.8 MPa.
2. Pressing Stage: Diaphragm inflated secondary pressure to 1.2-1.5 MPa, for 10-15 minutes.
3. Discharge Stage: Automatically pull out the filter plate, cake falls off (Note: Operate after stopping the machine and releasing pressure 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 frost prevention are necessary in low-temperature winter conditions. We currently have such products in stock, offering fully automatic container diaphragm 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 solution tailored to your needs.
