A pipeline type slag remover and its use method

Abstract

The invention relates to a pipeline type sludge slag remover and a use method thereof. The slag remover comprises a horizontal transverse pipe body, wherein a sludge inlet and a sludge outlet are formed in the pipe body; a spiral conveying assembly is transversely arranged in the inner cavity of the pipe body, and the spiral conveying assembly is electrically connected with a driving device; a dehydrating and squeezing device is also arranged in the pipe body; the spiral conveying assembly is respectively connected with the sludge inlet and the sludge outlet; the spiral conveying assembly comprises a slag spiral conveying rod and a sludge filtering net, and sludge is filtered by the sludge filtering net and then conveyed to the sludge outlet to be discharged out of a tank; slag is conveyed to the dehydrating and squeezing device by the slag spiral conveying rod; and the dehydrating and squeezing device is connected with a slag discharger arranged at the outer side of the pipe body. The pipeline type sludge slag remover has the advantages of being simple in structure, reasonable in design, totally-enclosed, integrated in slag removal and dehydration, capable of reducing influences of subsequent treatment processes to equipment, low in production and maintenance cost, high in degree of automation, excellent in sludge filtering and slag removal effect, and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a pipeline type sludge remover and its use method, which is mainly suitable for primary sludge, secondary sludge, mixed sludge, septic tank sewage in sewage treatment plants, etc. Removal of fine slag in mud. Background technique [0002] With the acceleration of urbanization and industrialization, the impact on the environment is becoming more and more serious. The protection of urban water environment is more important than before. The emergence of a large number of urban sewage treatment plants has effectively relieved the pressure on the urban water environment, but it has also brought The problem of how to deal with sludge in sewage treatment plants. Sludge is composed of bacterial micelles, organic matter, heavy metals, salts, and parasite eggs formed by various microorganisms. If it is not handled properly, it will easily cause secondary pollution, and it will in...

AI Technical Summary

Problems solved by technology

Some sewage treatment plants dry the sludge and then incinerate it or bury it deep, but the effect is not good, and the treatment cost is relatively high

In addition, the sludge also contains a large amount of slag. These slag particles have a large radius, and it is difficult to effectively separate them by conventional treatment, which also causes defects such as high sludge treatment costs. At the same time, this kind of sludge deslagging treatment The machine also has defects such as unreasonable structural design, poor processing effect, and low degree of automation.
