Sludge breaking and centrifugal filtration integrated machine

Abstract

The invention relates to a sludge breaking and centrifugal filtration integrated machine, and aims to provide a sludge breaking and centrifugal filtration integrated machine which is low in running cost, good in sealing property and small in occupied area. The sludge breaking and centrifugal filtration integrated machine comprises a base, a transmission device, a sludge breaking device and a centrifugal filtration device, wherein the transmission device comprises a belt pulley, a belt, an inner shaft and an outer shaft, wherein the inner shaft and the outer shaft are concentric and are respectively connected with the motor through the belt pulley and the belt, the sludge breaking device comprises a breaking cavity fixedly connected with the base through a bracket, fixed discs arranged on the inner wall of the breaking cavity and movable discs arranged on the inner shaft, the fixed discs and the movable discs are distributed in a staggered manner along the axial direction, the centrifugal filtration device comprises a filtering cavity shell, a water collecting channel with a water outlet pipe at the bottom, an elastic scraper, an annular baffle, and a filtering rotating hub arranged on the outer shaft, the bottom of the filtering cavity shell is fixedly connected with the outer side wall of the water collecting channel, a slag outlet hole is arranged at the lower part of the side wall of the filtering cavity shell, the annular baffle is arranged at the outer side of the upper edge of the filtering rotating hub, and the lower end of the elastic scraper is fixed on the inner shaft through a scraper rack.

Description

technical field [0001] The invention relates to an integrated machine for sludge cracking and centrifugal filtration. Background technique [0002] With the popularization of municipal sewage treatment facilities, the amount and depth of sewage treatment continue to increase, and the amount of excess sludge produced by sewage treatment plants is increasing. The demand for process equipment for processing and disposing of excess sludge is also increasing. Because most of the organic matter in excess sludge exists in microbial cells, and the cell wall of microbial cells is a stable semi-rigid structure, which plays a role in protecting cells. The process requires a longer residence time. Conditioning and disintegration of biological cells of excess sludge are the premise and key of subsequent sludge treatment process. Existing sludge cracking methods mainly include ball milling, high-pressure jetting, heating, chemical, and ultrasonic cavitation. The essence is to use mechan...

AI Technical Summary

Problems solved by technology

If the existing sludge cracking technology is introduced into the process of the existing sewage treatment plant, it is necessary to make major changes to the existing process facilities, and the transformation investment and operating costs are relatively large

In addition, the current traditional filter press is not well sealed, and the odor generated during the filter press process will cause certain pollution to the surrounding environment
