Coal mining sewage treatment device

Abstract

The invention discloses a coal mining sewage treatment device, and relates to the technical field of sewage treatment. The coal mining sewage treatment device comprises a bottom plate, wherein a filter and a storage device are fixed to the top of the bottom plate, and the filter is in a hollow cylinder shape. According to the coal mining sewage treatment device, sewage entering the filter can be filtered by arranging a rotary filter screen, so that coal fragments in the sewage stay on the surface of the rotary filter screen, the sewage can scour the surface of the rotary filter screen by guiding the flowing direction of the sewage through the water inlet pipe, coal fragments on the rotary filter screen can be tightly attached to the inner wall of the filter, when the rotary filter screen passes through a material leakage door plate, an anti-adhesion mechanism opens the material leakage door plate, so that the coal fragments filtered from the rotary filter screen automatically enter the storage device, only the coal fragments in the storage device need to be cleaned regularly subsequently, and the coal fragments on the filter screen do not need to be cleaned.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a coal mining sewage treatment device. Background technique [0002] Coal is a solid combustible mineral that was buried in the ground by ancient plants and gradually formed through complex biochemical and physical chemical changes. During the coal mining process, a large amount of sewage will be produced, which contains a large number of coal fragments. These coal fragments Blocks will cause greater damage to the surface soil. [0003] The existing coal mining sewage treatment method usually directly uses the filter to filter the coal fragments in the sewage, and then regularly treats the coal fragments on the filter. It affects the treatment efficiency of coal mining sewage, and it may be inconvenient to remove the coal fragments because the coal fragments are stuck inside the filter holes on the filter screen, so there are certain defects.
