High efficiency coal mine water purification device

Abstract

The invention discloses a high efficiency coal mine water purification device, which consists of a precipitation system and a filtration system. The precipitation system includes a columnar precipitation tube, a water inlet pipe is disposed at a side on the upper part of the precipitation tube, the bottom end is equipped with a collecting bucket, the inner cavity of the precipitation tube is equipped with a rotation shaft and a steady flow partition plate, the upper end of the rotation shaft is rotatably limited in a hanging seat, the middle part is welded with blades, and the lower end is welded with a particle scraping plate, the lower end face of the particle scraping plate abuts against a bottom end face of the precipitation tube cavity, and the steady flow partition plate is provided with a shaft sleeve and through-holes. The filtration system is composed of a multi-stage filtration tank and a membrane filter, the multi-stage filtration tank includes tank bodies, each tank body is equipped with a filter plate, a low support plate and a high support plate. In the invention, the precipitation system and the filtration system are arranged separately, the precipitation system can precipitate most solid particles and scrape the particles into the collecting bucket automatically, and the filtration system utilizes the multi-stage filtration tank for further removal of solid particles, thus avoiding filter membrane blocking phenomenon, guaranteeing the use effect and service life of the filter membrane, and improving the water filtration efficiency.

Description

technical field [0001] The invention relates to the field of coal mine sewage treatment, in particular to a high-efficiency coal mine water purification device. Background technique [0002] "Green mine" refers to the whole process of mineral resources development. It is necessary to strictly implement scientific and orderly mining, and to control the disturbance of the mining area and the surrounding environment within a controllable range. The definition of a green mine. In terms of time and content, scholars generally agree on the division of three stages of green mine development. That is to say, the first stage is the concept of "green mine" proposed by Britain, the United States and other western countries in the 19th century. The content of "green mine" is to beautify the surrounding environment of the mining area and protect the vegetation in the mining area. The elements of green mines in this period are mine green protection and restoration. The second stage is ...

AI Technical Summary

Problems solved by technology

Conventional coal mine water treatment methods are expensive and incomplete, and due to the relatively high degree of solid-liquid mixing, when conventional coal mine water treatment equipment is used for treatment, the filter membrane is prone to clogging in a short period of time Phenomenon, the precipitated solid particles cannot be collected and processed in time

In addition, conventional coal mine water treatment equipment also has the problem of low treatment efficiency
