A wet coal mine dust collector

Abstract

The invention discloses a novel wet dust collector for coal mines. The novel wet dust collector for the coal mines comprises a shell, a dust collection hood and an exhaust hood. The dust collection hood and the exhaust hood are mounted at the left end and the right end of the shell correspondingly. An outer clamp cover is mounted at the right end of a position where the duct collection hood is connected with the shell, and atomizing holes are formed in positions where the inner part of the outer clamp cover is contacted with the shell. The outer clamp cover is connected to a mixing valve, the mixing valve is connected to a water pressure tube and an air pressure tube, and the other valve port of the mixing valve is connected to an ejection flow nozzle. The ejection flow nozzle is connected to a front support frame and a grid mesh is arranged in the position where the ejection flow nozzle is connected with the front support frame. The front support frame is provided with a main shaft, a dust catching net is mounted on the main shaft, the dust catching net is fixed to the main shaft through the frame of the net, the other end of the main shaft is mounted in the center of a rear support frame, a steel net is arranged on the right side of the rear support frame, a dryer is arranged on the right side of the steel net and the dryer can dry the gas with water vapors.

Description

technical field [0001] The invention belongs to the technical field of dust collectors, and relates to a coal mine dust collector, in particular to a wet coal mine dust collector. Background technique [0002] Coal mine safety issues mainly include accidents such as coal mine gas explosion, fire and water seepage. However, mine dust also affects the health of workers and threatens production safety in mining operations. Mineral dust is very harmful, mainly in the following aspects: polluting the workplace and causing occupational diseases. Mild cases will suffer from respiratory inflammation and skin diseases, and severe cases will suffer from pneumoconiosis; some mineral dust (such as coal dust, sulfur dust) can explode under certain conditions; accelerate mechanical wear and shorten the service life of precision instruments; Visibility increases the occurrence of industrial accidents. Among them, pneumoconiosis and mine dust explosion are the most harmful, directly endan...

AI Technical Summary

Problems solved by technology

At present, mine dust has become a prominent problem in the safety production of coal mines in my country. However, the current coal mine dust removal devices generally do not have high dust removal efficiency. The pipeline connection of the dust collector is then detected by the corresponding monitoring module. The dust removal circuit adopted is long, and there are many equipments erected in the mine, which is not conducive to the layout of the mine and the operation is complicated.
