Structural Features and Dehydration Process of Shallow Loose Sludge Dewatering Machine

- Jun 22, 2018-

Compared with ordinary sludge dewatering machines, there are obvious differences in the structure of the stacked screw dewatering machine. First, the stack screw body of this type of dehydrator is mutually stacked by a fixed ring and a moving ring, and the screw shaft penetrates through the filter device formed therein. Based on the analysis of the operation characteristics of the superfluous sludge dewatering machine, the former can be attributed to the enrichment department, and the latter is to the dehydration department.


In the use of stacked spiral sludge dewatering machine, it will also feel very convenient. This is because when the structural design is performed, the pitch of the filter formed between the fixed ring and the moving ring and the pitch of the screw shaft gradually decrease from the enrichment section to the dewatering section. Therefore, with the operation of the equipment, the rotation of the screw shaft will not only continuously promote the transport of sludge from the enrichment section to the dehydration section, but also may drive the swimming ring to clean the filter joint to prevent clogging.


According to the operation of the superfluous screw dewatering machine, its working process can be mainly divided into three stages. The first stage is concentration, the specific content is: When the screw pushes the shaft to rotate, the multiple solid laminated plates set on the periphery of the pushing shaft relatively move, and under the action of gravity, the water is filtered out from the gap of the relatively moving laminated plate. Achieve rapid concentration.
