Belt filter press river channel desilting belt filter press belt sludge filter press

Belt filter press is a kind of equipment widely used in sludge treatment. It is very important to know the use method of belt filter press.

The belt filter press is widely used in the sludge dewatering treatment of urban domestic sewage, textile, printing and dyeing, electroplating, papermaking, leather, brewing, food processing, coal washing, petrochemical, chemical, metallurgy, pharmaceutical, ceramic and other industries.

The belt filter press has 3 dewatering zones.The material evenly distributed on the belt filter press conveyor belt first enters the dewatering zone - gravity zone;Depending on the action of flocculant, more than 50% of the surface moisture is removed by oozing between the self-weight flocculants.The dehydrated coal slime passing through the dead weight zone is carried by conveyor belt to the second dewatering zone - wedge zone.In this area, the distance between upper and lower conveyor belt gradually decreases, and the coal slime is squeezed by upper and lower conveyor belt and dehydrated.The slime then enters a third dewatering zone - the compression and shear zone.In this area, as the diameter of the idler decreases, the pressure on the coal slime reaches the maximum, the up and down conveyor belt detour operation produces shear force, which enhances the dehydration of coal slime.After being compressed, cut and dehydrated, the filter cake is taken to the head of the lower conveyor belt machine, and the material discharge chute is discharged by the scraper.

The belt filter press has compact structure, novel style, convenient operation and management, large processing capacity, low filter cake moisture content and good effect.Compared with similar equipment, it has the following characteristics:

1 gravity dehydration section is inclined, which makes the sludge up to 1700mm from the ground, increases the height of sludge in the gravity dehydration section, and improves the gravity dehydration capacity.

2. The length of gravity dehydration section and the length of the second gravity dehydration section are more than 5m, making the sludge fully dehydrate and lose fluidity before pressing.At the same time, the gravity dehydration section is also equipped with special mechanisms such as reversal, and the minimum moisture content of the sludge filter cake is obtained by "wedge" and "S" shaped press.

3.The dewatering rollers adopt "T" type drainage tank, so that the large amount of water after pressing can be discharged quickly, so as to improve the dehydration effect.

4. Automatic control device is provided for the strainer belt deviation, the strainer belt tension and the strainer belt moving speed can be adjusted freely, and the operation and management are convenient.

5. Low noise and no vibration.

6. Low dosage of chemical drugs.
