An all-in-one machine for sewage filtration, dehydration and slag removal

Abstract

The invention provides a novel waste water filtering, dehydration and deslagging all-in-one machine. The machine comprises a machine frame, a slurry storage tank, a master-control integrated system, a vacuum filtration system, a distribution valve and scrapers; the master-control integrated system is used for controlling the working procedure of the vacuum filtration system; the slurry storage tank is fixed to the machine frame; the vacuum filtration system comprises a horizontally arranged rotating roller, multiple filtering rotary tables which are vertically installed on the rotating roller at intervals, a distribution valve and a vacuum device; one part of each filtering rotary table is placed in the slurry storage tank, and one part of each filtering rotary table is located above the slurry storage tank; the scrapers are located on the surfaces of the filtering rotary tables; the vacuum device and a back wash system are communicated with the filtering rotary tables through the distribution valve; an upper cover which can be opened or closed relative to the slurry storage tank is arranged on the slurry storage tank; the slurry storage tank is provided with a discharge port capable of being opened or closed. According to the novel waste water filtering, dehydration and deslagging all-in-one machine, multiple processes of waste water filtering, dehydration and deslagging can be achieved on one machine, and the machine has the advantages of being high in efficiency, standard in treated water discharge, wide in applicability and the like.

Description

technical field [0001] The invention relates to sewage treatment equipment; in particular, it relates to an integrated environmental protection treatment machine for a series of treatment of sewage containing solid mud, dehydration and slag removal. Background technique [0002] With the development of science and technology, the development of building materials, chemical industry, coal, medicine and other industries is becoming more and more rapid, and a large amount of sewage containing waste residue will be generated in the manufacturing process. If the amount of sewage is not very large or the solid content concentration is relatively high, a kind of sewage treatment equipment that directly filters out the slag is needed. [0003] Conventionally used sewage treatment methods are treated by chemical flocculation sedimentation and gravity sedimentation in advection sedimentation tanks. Chemical flocculants have certain pollution to water bodies and waste residues. Even af...
