Mixed collecting and crushing device and sewage comprehensive treatment system

Abstract

The invention discloses a mixed collecting and crushing device which comprises a protective housing and a mounting base which are connected integrally, a positioning inner ring, a mixing and grinding device and an upper cover; the mixing and grinding device comprises a crushing knife, a fixed outer millstone knife, a rotary millstone knife and a rotary shaft for connection; the fixed outer millstone knife sleeves the positioning inner ring and is fixedly mounted with the same; the rotary millstone knife and the fixed outer millstone knife are correspondingly arranged, and the rotary millstone knife is fixedly mounted with the rotary shaft through a connector, the crushing knife is fixedly mounted with the rotary shaft through a connector, and the crushing knife and the external end portion of the fixed outer millstone knife are arranged in an aligned manner, so that the crushing knife and the rotary millstone knife rotate relative to the fixed outer millstone knife; and a matched surface is formed between the fixed outer millstone knife and the rotary millstone knife, and a gap is formed between the matched surfaces, and a grinding gap is formed between the gaps. The mixed collecting and crushing device disclosed by the invention is simple in structure and convenient to mount, and can effectively improve the treatment capacity and effect of sewage. The invention also discloses a sewage comprehensive treatment system.

Description

technical field [0001] The invention relates to a treatment technology for ship domestic sewage, in particular to a mixing collection and crushing device. The invention also relates to a sewage comprehensive treatment system. Background technique [0002] With the unprecedented development of the shipping industry and marine development, the pollution of the marine environment is becoming more and more serious, and human beings are paying more and more attention to the protection of the marine environment. The problem of domestic sewage pollution caused by shipping has gradually attracted people's attention. As a means of transportation in shipping, ships are a source of mobile pollution. The impact of domestic sewage discharge from ships on oceans and inland rivers cannot be ignored as the number of ships increases. [0003] However, the existing ship sewage mainly includes kitchen garbage sewage, black water and gray water, and electrolysis, flocculation and sedimentatio...

Problems solved by technology

[0003] However, the existing ship sewage mainly includes kitchen garbage sewage, black water and gray water, and electrolysis, flocculation and sedimentation after mixed treatment of the three kinds of sewage are required, and the existing ship sewage treatment equipment cannot even handle mixed sewage. , and some often have low treatment efficiency for mixed sewage. Ordinary equipment needs to be crushed for the solids in the se
