Description of ZPG type vacuum filter (tailings)

ZPG disk vacuum filter

Suitable for tailings dewatering and drying heap

Summary

Compared with the traditional belt filter and filter press, the disc vacuum filter has many advantages, such as low water content, small floor area, easy operation and maintenance, and large processing capacity. Equipment has been widely used in iron concentrate tailings, flotation copper tailings, lead and zinc tailings, quartz sand tailings, phosphorus tailings, power plants gypsum, hydropower stations, sediment, building materials and other materials dehydration.

The technology of processing to produce a large number of low concentration tailings by concentrating equipment pre dehydration, improve the pulp concentration into the disc vacuum filter for dewatering, cake after dewatering can be used for underground tunnel filling, also can be used as building material in use. For the fine particles, which are difficult to precipitate and concentrate, we can add some flocculant to accelerate precipitation and improve the dewatering effect of the filter before concentrating.

Technical characteristics

1 、 filter fan made of high strength polypropylene, high strength, reasonable structure design, strong and durable.

2. The fan handle is die-casting at once, with high strength. The caliber of the suction hole is increased, and the filtrate water can flow rapidly, and no water is accumulated in the filter fan.

3, for corrosion and special requirements, can be equipped with stainless steel bolts.

4. The filter cloth is made of German fabric, and the multi-layer fiber structure and supporting base fabric make it extremely compact and stable. The utility model has the advantages of smooth surface, uniform pore, easy blockage, and longer service life compared with domestic filter cloth.

5, the pore size of the filtrate pipe is large, which is beneficial to the rapid passing of filtrate water, and the residual liquid in the filter fan is prevented from affecting the water content of the mineral powder.

6, the main and the end of the distribution head, using a special structure, in the air balance zone, can quickly remove the filtrate pipe and filter fan residual liquid, reduce the cake

Water content.

7. The outside of the filter fan disc is compressed and fixed by segmented channel steel (or high strength engineering plastic), so it is convenient to install and disassemble. It is easy to change the filter cloth and fan the later stage.

8, mixing with VD type sealing ring, water seal, skeleton oil seal, combined packing multiple combination seal, long-term use does not leak slurry. According to the characteristics of tailing pulp size is fine, is not easy to precipitate, our company has developed a new maintenance free swing type mixing system, completely solve the problem of leakage of ore mixing system caused by not timely maintenance, reduce the maintenance cost.

9. The tank is welded by high quality steel. The bottom of the tank is lined with 16Mn steel plate (or corundum ceramic), which solves the problem that the bottom of the tank body is not wearable and easy to be damaged.

10. The friction plate and control panel are cast by high abrasion resistant boron phosphorus cast iron, and high wear resistant boron carbide is formed after casting. At the same time, the control panel of stepless boosting technology is developed for the characteristics of tailings. The technology can solve the problem of thin cake and low yield caused by fine particles.

11, using dry oil pump multi-point centralized automatic lubrication system, reduce maintenance, ensure the reliable operation of equipment.

12 、 filter cloth adopts automatic washing device, no need to stop production, work while cleaning, keep good dehydration effect.

13, the use of variable frequency speed regulation, according to the material concentration and flow adjustment, to ensure that the equipment to achieve the best working condition.
