Apparatus for removing hair from sludge

Abstract

The invention relates to an apparatus for removing hair from sludge. The apparatus comprises a filtration barrel, wherein both ends of the filtration barrel are respectively connected to an inlet end cover and an outlet end cover, a filtration mesh barrel is arranged inside the filtration barrel, a primary filtration chamber is formed between the outer wall of the filtration mesh barrel and the inner wall of the filtration barrel, the inlet end cover and the primary filtration chamber are communicated, the outlet end cover and the end head of the filtration barrel are communicated, and a winding device is arranged inside the filtration mesh barrel. According to the present invention, with the arranged combination of the filtration barrel, the filtration mesh barrel and the winding device, the hair can be conveniently removed from the sludge; the rapid connection member is used, such that the filtration barrel can be conveniently disassembled and replaced so as to clean hair and other soft fiber substances in the internal; and the multiple filtration barrel parallel connection structure is used, such that the non-stop on-line filtration barrel replacement can be achieved.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a device for removing hair in sludge. Background technique [0002] In recent years, with the rapid development of society, the amount of urban sewage is also increasing day by day, and due to the society's high attention to environmental protection, the number of sewage plants is also increasing rapidly, and sludge as a by-product of sewage plants is also inevitable. Substantial growth. How to economically, effectively and safely treat and dispose of the large amount of sludge produced by these sewage plants has become an urgent problem to be solved in the field of sewage treatment in our country. In the process of sewage treatment, the accumulation of inert inorganic substances (silt) in the sewage treatment system not only affects the sewage treatment effect, but also the accumulation of sludge and silt will accelerate the wear and tear of equipment and affect the normal opera...

AI Technical Summary

Problems solved by technology

In the process of sewage treatment, the gradual accumulation of inert inorganic substances (silt) in the sewage treatment system not only affects the sewage treatment effect, but also the accumulation of sludge and silt will accelerate the wear and tear of equipment and affect the normal operation of sewage treatment plants

Existing devices, such as Chinese patent ZL01240225.7, can realize the separation of biological substances and inorganic silt in sludge, but cannot remove soft fiber substances such as hair, which seriously affects the normal operation of subsequent sand removal equipment. Chinese patent 201110159013 mentions The hair separator to be found uses a horizontal screen, which can intercept hair and other impurities in the sludge, but in the actual project, the screen will be blocked quickly, so it must be shut down for cleaning, which cannot meet the actual needs of the project.

Chinese patent 201210188671 proposes a combined filter and proposes to use filter brushes and filter screens to remove soft fibrous substances such as hair, but the organic matter in the sludge will also be removed through the filter brush for multiple times, which will affect the biochemistry of subsequent sewage. Handling is not good, and soft fibrous matter such as longer hairs in the sludge will quickly clog the filter
