Industrial sewage treatment device

Abstract

The invention discloses an industrial sewage treatment device, and belongs to the technical field of sludge treatment equipment, the industrial sewage treatment device is provided with a shell for erecting a spiral shaft, a plurality of fixed rings and floating rings which sleeve the spiral shaft and are sequentially arranged in a staggered manner, and a gasket for forming a moving space of the floating rings is arranged between every two adjacent fixed rings; a sludge inlet is formed in one end of the shell, and a sludge outlet is formed in the other end of the shell; the connecting rod structure is sequentially connected with the floating rings; the floating ring comprises a plurality of connecting rod structures and a plurality of sheet bodies, the sheet bodies are sequentially spliced end to end to form the floating ring of a circular ring structure, a parting surface formed by contact of every two sheet bodies coincides with the circular shape of the floating ring, and every two adjacent sheet bodies are movably connected with the connecting rod structures through connecting parts. Abrasion is reduced, the service life is long, and the failure rate is low.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to an industrial sewage treatment device. Background technique [0002] Sludge is an inevitable product of sewage treatment in sewage treatment plants. Untreated sludge entering the environment will directly cause secondary pollution to water and the atmosphere, and pose a serious threat to the ecological environment and human activities. Sludge treatment can be divided into sewage Sludge dehydration process and sludge drying process; [0003] The traditional stacked screw sludge dewatering machine is mainly composed of a fixed ring, a moving ring, a gasket, a screw shaft and other components. The fixed ring and the moving ring are set outside the screw shaft, and the gasket is placed between the fixed ring and the moving ring. In this way, the fixed ring and the movable ring are assembled together to form a filter gap, and the sewage flows out from the filter ga...

AI Technical Summary

Problems solved by technology

[0003]The traditional stacked screw sludge dewatering machine is mainly composed of a fixed ring, a moving ring, a gasket, a screw shaft and other components. The fixed ring and the moving ring are sleeved on Outside the screw shaft, the gasket is placed between the fixed ring and the moving ring, so that the fixed ring and the moving ring are assembled together to form a filtering gap, and the sewage flows out from the filtering gap. When working, the screw shaft rotates and the moving ring The relative movement with the fixed ring can remove the sludge in the filter gap, so as to achieve the purpose of automatic cleaning. However, when the spiral blade of the screw shaft drives the swimming ring to swim in the gap between the fixed rings, the swimming ring There will be contact friction with the spiral blade, which will easily cause wear of the swimming ring and the spiral blade, the swimming performance of the swimming ring will gradually decrease, and the self-cleaning function of the equipment will deteriorate, resulting in a gradual decrease in dehydration efficiency;
