Belt filter press for Dehydration treatment of sand washing slurry

The belt filter press dehydration process can be divided into four important stages: pretreatment, gravity dehydration, wedge zone pre-pressing dehydration and squeezing dehydration.

Sludge fully reacts with coagulant will flow into material distributor in concentration part then dewatered along the movement of filter cloth under two-way guidance of mud rake and gravity. Reverse mechanism will transfer sludge to gravity dewatering area for further dehydration and in S-shape area pressed by roller with different diameters, sludge is again dehydrated between upper-lower filter cloth. Finally it will be scraped and cloth be cleaned during operation automatically. It features large productivity and high dewatering capacity and is applicable for treating sludge produced from tailings, ethanol residue, coal mud, paper mill , slaughter industry and car wash factories etc.

The belt filter press is mainly composed of a driving device, a frame, a press roll, an upper filter belt, a lower filter belt, a filter belt tensioning device, a filter belt cleaning device, a discharge device, an air control system, and an electrical control system.

It is widely used in washing sand slurry dewatering treatment, and it is an ideal equipment for environmental treatment and resource recovery.

Advantages: It has a high treatment capacity, capable of processing a large amount of sludge in a short time. The continuous operation mode improves work efficiency. Also, it can achieve relatively high dewatering efficiency, reducing the moisture content of the sludge effectively. And it is relatively easy to operate and maintain, with a simple structure that is convenient for daily inspection and repair.
