Introduction to ZPG/GPT disc vacuum filter

ZPG/GPT disc vacuum filter is a device that uses vacuum as filtering power to separate solids and liquids from slurry. It is mainly

 composed of distribution head, bearing, material guide and discharge device, filter disc, main shaft, stirring device, tank body, 

ore feeding device, stirring transmission, main shaft transmission, centralized lubrication system and other main components. 

It absorbs the advantages of domestic and foreign models and optimizes the design for metal minerals with high density, fast 

sedimentation speed and high viscosity. It has the advantages of sturdy and durable structure, stable operation of filter disc, reliable 

automatic speed change stirring seal, and prevention of slurry leakage. The filter fan is made of high-strength engineering plastics 

with large porosity and high-strength nylon single thick wire filter cloth. The surface is smooth, the cake discharge rate is high and 

not easy to clog, and the service life is long. All these characteristics ensure that metal minerals obtain excellent dehydration indicators

 during dehydration.

Equipment picture (shipping)

Disc vacuum filter is a device that uses vacuum as filtering power to separate solid and liquid in slurry. ZPG disc vacuum filter is 

suitable for dehydration of iron ore and nonferrous metal concentrate, as well as dehydration in coal washing plants, non-metallic 

minerals, chemical industry and environmental protection.

The requirements for dehydration objects are as follows:

① Mineral particle size is 200 mesh to 400 mesh.

② Slurry concentration is 35%-65% (metallic minerals) or 20%-40% (coal and other light materials).

③ Slurry temperature is 10℃-50℃.

④ The material is non-corrosive (special design is required when handling corrosive materials).

Equipment in operation

Working Principle

The disc vacuum filter is a solid-liquid separation device. The filter disc is driven by a speed-regulating motor through a reducer and

 an open gear transmission. It rotates at a certain speed in a tank filled with slurry. When a filter fan of the filter disc is in the filter 

adsorption area, a pressure difference is formed on both sides of the filter medium with the help of a vacuum pump, so that the solid

 material is adsorbed on the filter medium (filter cloth) and forms a filter cake. The filtrate is discharged through the filtrate pipe and

 the distribution head. When this filter fan is separated from the slurry level and enters the dehydration area, the filter cake is 

continuously separated from the water under the suction force of the vacuum, and further discharged from the filtrate pipe and the 

distribution head, so that the filter cake is dried. After entering the unloading area, the filter cake is unloaded from the filter disc with 

backblowing and a scraper, falls into the discharge trough, and is transported away by the ore collection belt conveyor. The entire 

operation process is carried out continuously.

Technical features

1: The new filter fan has uniform distribution of dehydration holes, reasonable porosity, high strength, long service life, and a large 

effective area of the filter fan, which improves the processing capacity of the machine;

2: The main drive has infinitely variable speed, which can be adjusted arbitrarily according to the concentration and flow of the 

material to achieve the ideal working effect;

3: Multi-point dry oil pump, centralized multi-point automatic lubrication, to ensure the normal operation of the equipment;

2: The main drive has infinitely variable speed, which can be adjusted arbitrarily according to the concentration and flow of the 

material to achieve the ideal working effect;

3: Multi-point dry oil pump, centralized multi-point automatic lubrication, to ensure the normal operation of the equipment;

4: 20 18-degree arcs are used Small pieces are interlocked continuously to press the filter fan and position it in a plane, making it 

time-saving and labor-saving to replace the filter fan and filter cloth;

5: The friction plate is made of special wear-resistant cast iron, which has a good sealing effect with both rigidity and flexibility;

6: The main shaft head of the filtrate tube is a high-strength wear-resistant composite steel pipe, which makes it have a longer 

service life;

7: The stirring shaft end adopts rubber packing and a four-combination water seal to prevent slurry leakage;

8: The filtrate tube is at the filter fan interface, and the mold positioning and direct welding are adopted to reduce the leakage points;

9: The new filter cloth cleaning device maintains its good dehydration effect;

10: The distribution head has a large empty capacity, which improves the air extraction rate and filtrate discharge effect.
