Wastewater Treatment Screw Filter Press Spiral Sludge Dewatering Machine

Product Description

Product Description

Screw sludge dewatering machine is a water treatment equipment widely used in municipal sewage treatment projects and petrochemical, light industry, chemical fiber, paper making, pharmaceutical, leather and other industrial industries.It has the following advantages: 1. Wide application scope  2. Equipment should not be easily blocked  3.Continuous automatic operation   4. Saving operation cost  5. No secondary pollution   6. Lightweight and durable   7. Saving project investment  secondary pollution   8. Improve phosphorus removal function.The discharging device is a very important part of the screw sludge dewatering machine, which determines the work efficiency, sewage purification quality and service life.In view of the  situation, the design and production of the  discharging device of our company broke the conventional production mode of the screw sludge dewatering machine, and finally determined the structure form of mortise and tenon embedding combination welding after many demonstration tests. Due to the use of mortise and tenon structure form, this structure form has: positioning datum consistency and high positioning accuracy, small welding deformation, production, assembly process most of the welding fixture fixture is no longer used, high production accuracy, production efficiency than the traditional structure form more than one times, and save materials.  

Working principle

1. Concentration: When the screw driving shaft rotates, the multiple active laminates located outside the driving shaft move relative to each other. Under the action of gravity, water filters out from the laminates that move relative to each other to achieve rapid concentration.  
2. Dehydration: after concentration, the sludge moves forward with the rotation of the spiral shaft;  Along the direction of mud cake exit, the pitch of the spiral shaft gradually decreases, the gap between the rings also gradually decreases, and the volume of the spiral cavity keeps shrinking;  Under the action of the back pressure plate at the outlet, the internal pressure gradually increases, and under the continuous operation of the screw driving shaft, the water in the sludge is extruded and discharged, and the solid content of the filter cake increases constantly, and finally the continuous dehydration of sludge is realized.  
3. self-cleaning: the rotation of the spiral axis pushes the moving ring to rotate continuously. The equipment relies on the movement between the fixed ring and the moving ring to realize the continuous self-cleaning process, so as to cleverly avoid the blocking problem commonly existing in the traditional dehydrator.
