Fold screw sludge dehydrator is using the principle of the screw extrusion, through strong extrusion screw diameter and pitch changes, and the tiny cracks between swimming ring with fixed ring, implementation to squeeze dewatering sludge, is a new type of solid-liquid separation equipment.

Fold screw sludge dehydrator adopted many overlapping slice spiral filter way, have the function of self cleaning filter seam, not blocked, water saving &electricity saving, durable, created the low sludge (2000 mg/l ～) direct dehydration, can achieve 24 hours continuous unmanned operation, at the same time greatly reduce design, construction, operation and maintenance costs.

The speed of the screw shaft is about 2-3 RPM, no vibration, smaller noise. The fold screw body has automatic cleaning function, no clogging problem, only need little water to flush, no secondary pollution.

The integrated, overall and compact design, significantly saving the operating costs;

Low speed screw extrusion technology, leading to the significant reduction of power consumption;

Not easily blocked device, greatly reducing flushing water;

24 Hours unmanned automatic operation, a significant reduction in labor costs.

Working principle:

Sludge in concentrating section after gravity concentration, transported to dewatering section, in the process of forward, filtering seam and screw pitch became smaller, as well as the back plate blocking, create great pressure, volume shrinking, achieve the goal of fully dehydration

Yuzhou Huade Environmental Technology Co., Ltd. is a professional manufacturer of filtration equipment. It is a major manfacturer and exporter based of filter press in China. The general manager Zhang of Shuangfa engaged in filtration equipment industry began in the 1980s. In 1995, the co-partnership company (Yuzhou Shuangfa Chemical Industry Machinery Co., Ltd) founded.It is China's first batch of filtration equipment R & D and producers.With a plate factory established in 1997 and a pump factory established in 2000, Shuangfa became a group. 

Boasts its 80000 square meters production base and owns complete modernized metal cutting equipment, equipped with advanced Solidworks 3D mechanical design and Computerized Simulation Test System, Shuangfa has cultivated a professional technology and after-sales service team, and successfully achieved ISO9001:2000 Quality Management Certificate and EU CE Certificate. 

Till now, we have formed a whole production chain with main products: series pressure filter, vacuum belt filter press, belt filter press, various plates, series pumps, centrifuges, water purification equipment, processing equipment, conveyor equipment, washing machine.The products are widely used in chemical industry,food, environmental protection, mining, metallurgy, petroleum, pharmaceutical, papermaking, coal, washing and contaminated water treatment and other industries of liquid separation.Advanced technology content, high reliability, low operation and maintenance cost have enabled our products to take the leading position in the field. 

Our products have been exported to more than 130 countries and are widely used in variety of industries. Being innovative and perfect is our incessant pursuit, and also our vigor source of energy and harmony.
