ZPG disk vacuum filter (quartz, potassium feldspar)

Suitable for dehydration of potassium albite powder (quartz sand)

Summary

Potassium sodium feldspar is widely used in ceramics, glass, enamel, potassium making and other industries, and has a wide range of applications. However, with the development of various trades and applications in the new field, higher requirements have been put forward for the fineness, iron content and whiteness of potassium and sodium feldspar powder. Superfine grinding, super fine grading, feldspar powder with high whiteness because of its small size, easy to produce powder agglomeration phenomenon caused by rapid precipitation and easy bonding materials, traditional disk or belt vacuum filter can not meet the powder processing capacity and moisture requirements.

Our company carries out a number of technical improvements and innovations on the original disc vacuum filter, and introduces a reliable disc vacuum filter for potassium and sodium feldspar powder. To overcome the problem of ultrafine powder agglomeration, and improve the processing capacity (0.4 ~ 0.5 t/h / M), reduce product moisture content (MC = 16%).

Technical characteristics

In order to avoid the production of machinery, iron and rust mixed with stone powder, causing two pollution, equipment and pulp contact parts of 304 stainless steel material.

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 、 filter fan tension bolt made of 304 stainless steel.

4, the use of German technology potassium potassium feldspar powder (quartz) special filter cloth. Good ventilation, but not easy to plug, high strength and long service life.

5. The filter pipe is made of 304 stainless steel tube to prevent rust pollution. 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.

7. The outside of the filter fan disc is a sectional type high-strength engineering plastic press plate, which is convenient for installation and disassembly, and is convenient for replacing the filter cloth and the filter fan.

8, mixing with VD type sealing ring, water seal, skeleton oil seal, combined packing multiple combination seal, long-term use does not leak slurry. The mixing blade and mixing shaft are made of 304 stainless steel.

9, the groove and pulp contact parts are welded with 304 stainless steel plates.

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, according to the characteristics of stone powder, the control panel of stepless boosting technology is developed. 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 flushing device, without stopping production, cleaning while working, maintaining good dewatering effect, and improving production efficiency.

13, spindle and mixing frequency control, according to the material concentration and flow adjustment, to ensure that the equipment to achieve the best working condition.

14, the use of advanced SX series automatic water discharge device, compared to the traditional liquid discharge tank, the device can effectively avoid the filtrate water discharge, suction into the vacuum pump, resulting in vacuum pump wear.
