Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a screw press sludge dewatering machine. Background Art

[0002] The laminated spiral sludge dewatering machine is a water treatment equipment widely used in municipal sewage treatment projects as well as petrochemical, light industry, chemical fiber, papermaking, pharmaceutical, leather and other industrial industries.

[0003] The main body of the dehydrator spiral stack is a filtering device formed by a fixed ring and a movable ring stacked on each other into a cylinder, with a spiral shaft passing through it. Because the inner diameter of the spiral shaft is larger than that of the movable ring, the rotation of the spiral shaft drives the movable ring to move in a circular motion to prevent blockage. The gap between the fixed ring and the movable ring gradually becomes smaller from the concentration section to the dehydration section along the direction of the mud cake outlet. After the sludge is concentrated by gravity in the concentration section, it is transported to the dehydration section and forced dehydration is achieved under the action of the internal pressure generated by the back pressure plate at the discharge outlet.

[0004] However, the existing spiral press sludge dewatering machine cannot monitor the moisture in the sludge after it is discharged, so that the abnormality of the dewatering machine cannot be detected in time, resulting in a decrease in the working efficiency of the dewatering machine.
