Description

TECHNICAL FIELD

[0002] The sludge dewatering machine is a continuous operation sludge treatment equipment, and is popular among the public due to the following characteristics: low water content of discharged sludge, stable operation, low energy consumption, relatively simple control and management, and convenient maintenance. Since the sludge is still in a liquid flow state and has a large volume after being concentrated or digested, it cannot be transported and disposed. In order to further reduce the water content and make the water content of the sludge as low as possible, the sludge must be dewatered to reduce the volume of the sludge and facilitate transportation. The filter main body is formed by the mutual layering of the fixed ring and the movable ring and the penetration of the screw shaft thereinto. The sludge is fully dewatered through gravity concentration and internal pressure generated by the back pressure plate during the propulsion process. The filtrate is discharged from the filter gap formed by the fixed ring and the movable ring, and the sludge cake is discharged from the end of the dewatering part.

[0003] However, in the prior art, the sludge may leak out through the filter gap during the use of the screw type dewatering machine. These sludge will accumulate on the outside of the screw type dewatering machine, thereby causing blockage of the drainage filter gap and affecting the discharge of sewage during the operation of the dewatering machine, thereby reducing the efficiency of the dewatering work.
