详情描述
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 12MPa) 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 and Advantages
1. Precision Filtration: Utilizes activated carbon and other filtration materials to handle mildly 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: The diaphragm secondary extrusion technology can reduce the moisture content of the 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 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 pressurization to 1.2-1.5 MPa, for 10-15 minutes.
3. Unloading Phase: Automatically open the filter plate, cake falls off (Note: Operation requires shutdown and pressure release 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 frost prevention are essential 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 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.
