Mining multi-element solid-liquid separator and underground coal-water separation method

Abstract

The invention belongs to the technical field of solid-liquid separation equipment for coal mines. The mining multi-element solid-liquid separator comprises a base, a sieve tray, a vibrator, a first separation barrel body, a second separation barrel body and an upper cover, wherein the sieve tray is supported on the base through a plurality of groups of springs; the vibrator is arranged at the lower part of the sieve tray; the first separation barrel body is arranged at the upper part of the sieve tray; a water receiving hopper is arranged in the first separation barrel body; the second separation barrel body is arranged at the upper part of the first separation barrel body, a screen is arranged between the first separation barrel body and the second separation barrel body, a buffer hopper is arranged in the second separation barrel body, a material distribution opening is formed in the middle of the buffer hopper, and a material distributor is arranged at the material distribution opening. The invention further discloses an underground coal-water separation method. The coal-water particle mixture can be subjected to effective high-precision solid-liquid separation by utilizing favorable conditions and multi-point arrangement in the coal mining process, separated coal enters a coal conveying system again, and the economic benefit of a coal mine is improved.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation equipment for coal mines, and in particular relates to a multi-stage solid-liquid separator for mines and an underground coal-water separation method. Background technique [0002] The coal mining process involves water prevention and control. In order to ensure the normal operation of the underground drainage system, reduce the silt flowing into the water tank or sedimentation tank, and reduce the annual manual cleaning of the sediment and silt in the drainage system, it is necessary to systematically analyze the source of the silt and treat the silt in the water. Coal-water mixture exists in two major production links in the process of mining coal. One is the drilling operation site, which requires a large amount of water to flush the coal hole and produce a large amount of coal-water mixture; A certain amount of coal-water mixture. The coal-water mixture flows into the water ta...

Problems solved by technology

[0003] At present, the method of cleaning the ditch in the coal mine roadway basically relies on manual excavation with a shovel along the ditch. According to the labor operation and safety regulations of the coal mine, single-person work is strictly prohibited. More than two people are required to clean the ditch. Affect roadway transportation efficiency, personnel safety hazards, physical labor intensity and other issues

If the coal-water mixture is not cleaned up in time, it will flow into the sedimentation tank and the water tank, which will cause more problems, such as: affecting the volume of the water tank, reducing the service life of the drainage system, high cleaning costs, and many dangerous factors for personnel working in low-lying areas , a large number of workers, high cleaning costs, etc.
