Working Principle
  1. 1.Before entering the drum concentration belt dewatering integrated equipment, the sludge is fed into the mixed reaction tank through a flocculant preparation and dosing system.
  2. 2.In the mixed reaction tank, the sludge is thoroughly mixed with the polymer flocculant through stirring. The sludge quickly condenses from fine particles to large particles, forming a network structure of large agglomerates, and then enters the slowly rotating pre dewatering drum. During the transportation of sludge to the end of the drum by a special device, most of the free water is released through a filter cloth to achieve concentration effect. The effluent is collected by the filter tank and separated from the solid sludge.
  3. 3.The pre dehydrated sludge slides from the inclined plate onto the upper filter belt of the belt filter press, and then is transported to the lower filter belt. Between the upper and lower filter belts, the sludge is further dehydrated and discharged due to the gradual pressure increase and shear force.
  4. 4.The yield and dryness of sludge can be controlled by a continuously variable speed device, and the amount of cleaning water can be adjusted by a liquid level control system.

Product Advantages

 
 
  1. Manufacturing of SUS304 (stainless steel) main structure for sludge thickener.
  2. The air pressure cylinder induction action correction system controls the operation of the filter cloth within a certain range based on the displacement principle.
  3. Spring type compression and tensioning device can adjust the tension as needed to reduce the moisture content of the filter cake.
  4. Continuous treatment and high efficiency of sludge dewatering machine.
  5. The most suitable ones are those with light volume and small venues.
  6. The operation and maintenance of the sludge thickener are simple, and the labor cost is low.

Application

 
  1. 1.Various industrial wastewater sludge concentration treatment;
  2. 2.Solid liquid separation in industrial processes such as food, chemical, and mining;
  3. 3.Urban sewage treatment plants;
  4. 4.Slaughter and livestock sludge concentration treatment.
  5. 5.Widely used in various fields such as environmental protection, dairy products, renewable resources, chemicals, pharmaceuticals, navigation, energy, and petroleum gas.
