The rotary drum thickening belt filter press is mainly used for the treatment of sludge that has not been concentrated in the concentration tank (such as the remaining sludge of the A/O method). It relies on the rotary drum concentration to increase the sludge concentration, which is equivalent to having the dual functions of concentration and dehydration. The processing capacity is higher than that of pure filter press. Rotary drum thickening belt filter press is a new type of solid-liquid separation equipment that realizes squeezing and dehydration of sludge.

 

 

1. Before the sludge enters the integrated drum concentration and belt dehydration equipment, the polymer flocculant is driven into the mixing reaction tank through the flocculant preparation and dosing system.

2. In the mixing reaction tank, the sludge and the polymer flocculant are thoroughly mixed by stirring. The sludge quickly condenses from fine particles into large particles and forms large flocs with a network structure, and then enters the slowly rotating pre-dewatering rotor. Drum. When the sludge is transported to the end of the drum by a special device, most of the free water is released through the filter cloth to achieve a concentration effect. The effluent is collected by the filter tank and separated from the solid sludge.

3. The pre-dewatered sludge slides from the inclined plate to the upper filter belt of the belt filter press, and then is transferred to the lower filter belt. Between the upper and lower filter belts, the sludge is further dehydrated and discharged due to the gradual pressurization and shear force.

4. The output and dryness of sludge can be controlled by the infinitely variable speed device, and the amount of cleaning water can be adjusted by the liquid level control system.

 

 

1. The air cylinder induction correction system uses the displacement principle to control the filter cloth to operate within a certain range.

2. Spring-type compression and tensioning device can adjust the tension as needed to keep the moisture content of the filter cake low.

3. Continuous processing, high work efficiency.

4. Suitable for those with light size and small space.

5. Easy operation and maintenance, low labor cost.

6. Professional environmental engineering background, standardized mass production.
