Centrifugal solid-liquid separation equipment for sewage treatment

Abstract

The invention discloses centrifugal solid-liquid separation equipment for sewage treatment, and relates to the technical field of sewage treatment equipment. The centrifugal solid-liquid separation equipment comprises a shell, an upper cylinder and a lower cylinder are arranged in the shell, the upper cylinder is rotationally connected to the upper surface of the lower cylinder through a fixed shaft, a water inlet pipe is fixedly installed on the surface of the upper cylinder, and the surface of the upper cylinder is fixedly sleeved with a fixing ring; the fixing ring is fixedly installed on the inner wall of the shell. Through mutual cooperation of the structures, water-containing garbage is preliminarily dewatered in a centrifugal rotation and pressurization mode, solid garbage is compressed and dewatered, rolling and puncturing are conducted, the good garbage dewatering effect is guaranteed, the garbage dewatering efficiency is improved, and the problems that a traditional solid-liquid separation device cannot achieve a very high solid-liquid separation effect on solid garbage only through a stirring mode, and a good dehydration rate cannot be guaranteed for some garbage with relatively high water absorption capacity are solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a centrifugal solid-liquid separation equipment for sewage treatment. Background technique [0002] With the continuous improvement of people's living standards in our country, the production of domestic sewage is also continuously increasing. Since domestic sewage generally contains a large amount of solid waste, solid-liquid separation treatment is required when the solid waste in sewage is organically treated and recycled. . [0003] For example, the Chinese patent CN201711331789.9 discloses a centrifugal pressurized solid-liquid separation device. Through the setting of the communication mechanism, the solid-liquid mixture can be separated under the double action of centrifugal force and pressure, which can greatly improve the efficiency of solid-liquid separation. ;By setting the auxiliary support rod, the support of the separation cylinder is more stable...
