Concentrating and precipitating device under mine and water well

Abstract

The invention relates to a concentration and settlement device for use in coal and water wells, which is characterized by comprising a settling pond, a plurality of sloping plates (2), a scraping plate conveyor (3) and a pipe orifice, wherein the settling pond is arranged in an underground roadway and has an integral trapezoidal structure narrowing from top down, the bottom of the pond is provided with an equipment mounting platform and a bottom current pond (6) with a downward concave structure, the edge of the pond is provided with a mine water inlet and an overflow groove and the inclined angle of the side wall of the settling pond is more than 65 degrees; the plurality of sloping plates (2) are arranged on the middle upper part of an inner cavity of the settling pond in a mode of inclining 55 to 65 degrees, and the distance between the sloping plates is 110 to 130 millimeters; the scraping plate conveyor (3) is arranged on the equipment mounting platform arranged on the bottom of the pond and under the sloping plates; and the pipe orifice is used for connecting a slurry pump and is arranged on the side wall of the bottom current pond.

Description

Mine water underground concentration and sedimentation device Technical field: The invention relates to an underground concentration and sedimentation device for mine water, which is used for the treatment of underground mine water, and can simultaneously obtain high-concentration underflow and clear overflow water, thus solving the difficult problem of dredging underground water tanks. Background technique: Coal mine water refers to all the water that seeps into the underground mining space during the coal mining process. Mine mines are generally equipped with special water tanks. Mine water is collected in the mine water tank and then pumped out of the well by the drainage system. The mine water tank is an important facility for safe production in coal mines and prevention of mine floods. Since the mine water contains a large amount of impurities mainly including coal slime and sand, these solid particles will be carried into the water tank by the mine water and will be ...

Problems solved by technology

This traditional method not only has a large workload, but also takes a long time to clear and excavate, and the working environment is harsh, and it is difficult to clean and excavate

Mechanized cleaning of mine water tanks is a difficult problem that coal mining enterprises have been eager to solve for many years. However, for decades, dozens of cleaning machines have been developed in my country, but they have not been popularized and used. The main reason is that the situation in the mine is complex and changeable. The water tank dredging equipment and its supporting system have disadvantages such as single performance, low dredging efficiency, and incomplete solid-liquid separation, which cannot adapt to the complex and changeable working environment of the underground tank
