Qiuyuan Environmental Protection Stack Screw Sludge Dewatering Machine

- Jul 18, 2019-

The company carries out independent technological innovation according to China's national conditions, and develops a new generation of energy-saving sludge dewatering equipment with no pollution, wide application range, low energy consumption and simple operation and maintenance – the stacked screw sludge dewatering machine, which has got rid of the previous generations of sewage. The mud dewatering equipment is easy to block, can not handle low concentration sludge and oily sludge, and has high technical problems such as high energy consumption and complicated operation.

The stacking screw sludge dewatering equipment considers factors such as hydraulic co-directional, thin layer dewatering, proper pressure application and prolonged dehydration path in the dewatering mechanism. While ensuring the dewatering performance of the equipment, the energy consumption and water consumption are further reduced, the service life of the equipment is prolonged, and the goal of dehydration with high efficiency and energy saving is realized.

The stacked screw sludge dewatering machine can be widely used in municipal sewage treatment projects as well as water treatment systems in petrochemical, light industry, chemical fiber, paper, pharmaceutical, leather and other industrial industries. The actual operation proves that the stacked screw sludge dewatering can create considerable economic and social benefits for customers.

Working principle

Concentration: When the screw pushes the shaft to rotate, the multiple solid laminations disposed on the periphery of the push shaft move relative to each other. Under the action of gravity, water is filtered out from the relatively moving lamination gap to achieve rapid concentration.

Dehydration: The concentrated sludge moves forward with the rotation of the screw shaft; along the exit direction of the mud cake, the pitch of the screw shaft gradually becomes smaller, the gap between the ring and the ring gradually becomes smaller, and the volume of the spiral cavity shrinks continuously. Under the action of the back pressure plate at the outlet, the internal pressure is gradually enhanced. Under the continuous driving of the screw push shaft, the water in the sludge is squeezed out, and the solid content of the filter cake is continuously increased, finally achieving continuous sludge. Dehydration.

Self-cleaning: The rotation of the screw shaft pushes the swimming ring to rotate continuously. The device relies on the movement between the fixed ring and the swimming ring to realize a continuous self-cleaning process, thereby cleverly avoiding the clogging problem that is common in the traditional dehydrator.
