What’s a Disc Vacuum Filter?

disc vacuum filter adopts a polyurethane or industrial polypropylene filter plate, which is lightweight and corrosion-resistant. It is an excellent filter equipment for tailings filtration and dehydration in non-ferrous metal and non-metal beneficiation. Aiming at the characteristics of the high density of metal minerals, fast settling, and strong impact of filtrate-containing solid particles on the filter tube, has optimized the overall performance and reliability of each component of the vacuum disc filter. It can efficiently separate the solid particles from the slurry, fully guarantee the excellent dehydration index of the metal minerals in the solid-liquid separation and improve the ore grade.

provide ceramic filters, which use microporous ceramics as filter media, saving more than 90% energy consumption. The panel is covered with 3-5 micron pores, more suitable for tailings or finer mineral powder dehydration. It can resist almost all temperatures and has a long service life. Both are a new type of high-efficiency and energy-saving filter equipment.

Working Principle Of Disc Vacuum Filter

The components of the disc vacuum filter include filter disc, vacuum system, suspended matter supply system, filter cake cleaning system and slag discharge system, etc. Filter discs typically consist of flat or uneven filter media (usually fine-pore filter cloth or membrane) that trap solid particles or suspended matter while allowing liquid to pass through. Start spinning at low speed to ensure the liquid is evenly coated on the filter media when operating. The material flows into the center of the filter disc from the feed pipe, and the solid particles remain on the surface of the filter medium to form a filter cake. At the same time, the clarified liquid enters the collecting tank or pipeline below through the filter medium. Through the rotation of the filter disc, the filter cake can be continuously formed and removed, realizing a continuous solid-liquid separation process.

Advantages Of Disc Vacuum Filter

Widely used in many fields and industries such as mining, environmental protection, chemical industry, food, pharmaceuticals, etc., to achieve technical requirements such as solid-liquid separation, concentration and dehydration;
Automatic variable speed strong stirring, reliable shaft end seal, wear-resistant and durable;
Sturdy structure, smooth operation of the filter plate; high strength filter fan, large porosity;
High-strength filter cloth with smooth surface, high cake unloading rate and long service life;
Reduce wastewater discharge, achieve sludge dehydration and volume reduction treatment, and at the same time realize water recovery and recycling;
High finished product quality, waste reduction and building a friendly beneficiation environment.

Structure

The structure of disc vacuum filter mainly includes filter disc, drum, distributing head, vacuum system, discharging mechanism as well as frame and transmission system. The disc is responsible for solid-liquid separation, the drum rotates the disc to complete the filtration cycle, the distributor head distributes the liquid and collects the filtrate, the vacuum system provides negative pressure conditions, the unloading mechanism unloads the solid particles, and the frame and drive system provide support and power. These parts work together to achieve a continuous and efficient solid-liquid separation process.
