Centrifugal sludge dewatering equipment for sludge remediation

Abstract

The invention belongs to the field of dewatering equipment, particularly relates to centrifugal sludge dewatering equipment for sludge repair, and aims to solve the problems that large-particle sludge is attached to a filter screen due to the fact that existing sludge dewatering equipment needs to filter sludge, and meanwhile, sludge blocks are possibly accumulated on a sludge outlet pipe and cannot be discharged after flowing sludge is heated. According to the scheme, the equipment comprises a shell, a hollow rotating shaft is rotationally installed in the shell, a differential mechanism is fixedly installed at one end of the hollow rotating shaft, a spiral transfer plate is fixedly installed on the outer side of the hollow rotating shaft, a water outlet pipe and an inclined pipe are fixedly installed at the bottom of the shell, and an inclined box is fixedly installed at the bottom of the shell. Large-particle sludge attached to the filter screen can be extruded and crushed, the filter screen is prevented from being blocked by the large-particle sludge, meanwhile, sludge blocks accumulated on the sludge outlet pipe are extruded and ascended, and the situation that the sludge blocks are extruded and accumulated mutually and cannot be discharged is prevented.

Description

technical field [0001] The invention relates to the technical field of dewatering equipment, in particular to a centrifugal sludge dewatering equipment for sludge restoration. Background technique [0002] Sludge remediation is a kind of soil remediation. The existing sludge remediation process includes dehydration, drying and chemical purification, so that the sludge can be turned into normal soil that can be used for vegetation growth. Sludge remediation usually requires the use of centrifugal sludge dewatering equipment for treatment. Centrifugal dehydration equipment uses the density difference between solid and liquid phases to accelerate the settling velocity of solid phase particles under the action of centrifugal force to achieve solid-liquid separation. [0003] Existing sludge dehydration equipment needs to filter the sludge, resulting in the attachment of large particles of sludge to the filter screen. At the same time, after heating the flowing sludge, the sludge...
