Abstract

The invention relates to the field of sewage treatment equipment, and discloses a sludge centrifugal dehydrator for sewage treatment. The sludge centrifugal dehydrator comprises a machine base, a housing is arranged at the top of the machine base, a rotatable drum is arranged in the housing, a rotatable middle rotating shaft is arranged in the middle of the inner cavity of the drum, the drum and the middle rotating shaft are driven by a driving motor to rotate, and a differential mechanism is connected between the rotatable drum and the driving shaft on one side of the middle rotating shaft. Through the structural design of a positioning sleeve plate and a limiting sliding ring between two spiral impellers at a water outlet pipe in the rotatable drum, when the content of sludge in sewage is suddenly increased, the flow of the sewage and the sludge in the spiral conveying cavity is reduced through diversion by utilizing the water guide hole, so that a large amount of sludge can be conveniently conveyed to the centrifugal machine conical dewatering cavity on the left side along the outer side of the rotatable drum again, the problem that when the sludge amount is increased, an existing sludge centrifugal dewatering machine cannot discharge and separate the sludge in time, and consequently part of the sludge flows out along with sewage is effectively solved, and the sludge dewatering effect is guaranteed.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a sludge centrifugal dehydrator for sewage treatment. Background technique [0002] Sludge centrifugal dehydrator is a common environmental protection equipment for sewage treatment. It is widely used in industrial wastewater coagulation and sedimentation sludge treatment, industrial wastewater excess activated sludge treatment, urban sewer sludge treatment, etc. The existing sludge centrifuge The sludge of the dehydrator is sent into the drum by the hollow shaft, and is thrown into the drum cavity under the centrifugal force generated by high-speed rotation, and is separated from the solid sludge and water under the action of different centrifugal forces. Driven by the driving force, the conical end that is transported to the drum is continuously discharged from the outlet, and the separated clean water flows back along the inner side and is discharged from the other si...
