Diaphragm press filters are high-efficiency solid-liquid separation equipment that achieves material dewatering through the principle of pressure filtration. Their core structure consists of diaphragm filter plates, frames, and a hydraulic system. During operation, high pressure (such as 12MPa) is applied to squeeze the material between the filter plates, allowing the liquid to pass through the filter cloth and drain out, while the solid is retained to form a filter cake.
Features & Advantages:
Precision Filtration: Utilizes activated carbon and other filter materials to process mildly corrosive, low-temperature materials (such as lubricating oils) with high filtration precision.
2. Fully Automatic Operation: Equipped with PLC control system for automatic clamping, unloading, and cleaning.
3. Energy-efficient and High-performance: Diaphragm secondary squeezing technology can reduce the moisture content of filter cake to below 15%, significantly cutting down on drying costs.
4.Wide Application: Suitable for oil, water treatment, dye industries, with an effective filtration area of up to 250㎡.
Operation Process
1. Material Feeding Stage: The material is pumped into the filter chamber, with a recommended pressure control of 0.6-0.8 MPa.
2. Pressing Stage: Diaphragm expanded, secondary pressurization to 1.2-1.5 MPa, lasting 10-15 minutes.
3. Discharge Phase: Automatically open the filter plate, cake falls off (Note: Perform 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 protection are necessary in low-temperature winter conditions. We currently have such products in stock, offering fully automatic box-type diaphragm filter presses for precise filtration and efficient dehydration. Suitable for the oil and water treatment industries, these presses can operate at a working pressure of up to 12MPa.
