Improved dense medium rapid sedimentation water treatment device

Abstract

The invention discloses an improved dense medium rapid sedimentation water treatment device. The device comprises a cylindrical outer barrel body and a cylindrical inner barrel body which are vertically arranged, wherein the inner barrel body is coaxially arranged in the outer barrel body; a support is arranged at the lower end of the outer barrel body; a water outlet is formed in the bottom wall of the inner barrel body; the water outlet communicates with the outside by penetrating through the bottom wall of the outer barrel body and the bottom wall of the inner barrel body; a plurality of first plate bodies vertically arranged in the radial direction of the outer barrel body are evenly distributed between the outer barrel body and the inner barrel body; space between the outer barrel body and the inner barrel body is divided into a plurality of filtering cavities through the first plate bodies; first notches are formed in the first plate bodies, and a first filter screen or a first baffle is selectively installed in one of the first notches; a plurality of second notches are formed in the side wall of the inner barrel body at intervals, and second filter screens are installed in the second notches; and second baffles corresponding to the second notches are detachably arranged in the filter cavities. The improved dense medium rapid sedimentation water treatment device provided by the invention can select filtering frequency according to actual requirements.

Description

technical field [0001] The invention relates to the field of mine water treatment. More specifically, the present invention relates to an improved dense medium velocity sinking water treatment device. Background technique [0002] Coal mines are areas where human beings mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. Most of the coal mines in my country belong to underground coal mines. The scope of coal mines includes a large area above ground, underground and related facilities. Mine water It means that in the process of coal mining, groundwater is in contact with coal seams and rock formations, coupled with the influence of human activities, a series of physical, chemical and biochemical reactions have occurred, so the water quality has obvious characteristics of the coal industry, mine water containing suspended matter The content of suspended solids is much higher than that of surface water, a...

[0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. Most of the coal mines in my country belong to underground coal mines. The scope of coal mines includes a large area above and below ground and related facilities. Mine water refers to a series of physical, chemical and biochemical reactions that occur when groundwater contacts coal seams and rock formations during the coal mining process, coupled with the impact of human activities. Therefore, the water quality has obvious characteristics of the coal industry. The content of suspended solids in mine water containing suspended solids is much higher than that in surface water, and the sensory properties are poor; ; Mine water also contains waste engine oil, emulsified oil and other organic pollutants
