A mining hydraulic dedusting system and hydraulic dedusting method

Abstract

The invention relates to a mine hydraulic dust removal system. The mine hydraulic dust removal system is used for dust removal of an underground heading face of a coal mine and comprises a dust remover. An air inlet of the dust remover is connected with a high-pressure air cylinder. An air outlet of the dust remover is connected with a dehydrator. The dehydrator is connected with a ventilation pipe. The ventilation pipe is connected with a dust suction fan. A filter screen is arranged at an air inlet of the high-pressure air cylinder, the filter screen is arranged at an air inlet of the dust suction fan. The dust suction fan is connected with a hydraulic motor, and the hydraulic motor is connected with a hydraulic system. The hydraulic system is connected with a branch of the hydraulic system of a heading machine. The dust remover is provided with a buffer plate, a water inlet, five spraying nozzles and a drain pipe. The water inlet is connected with the five spraying nozzles. The buffplate is arranged in that dust remover. The dust remover is fixed to the heading machine through a fixed bracket. The mine hydraulic dust removal system has the advantages of large exhaust volume, good dust removal effect, avoidance of large amount of mud caused by wet-type dust removal, small resistance loss of the system, low energy consumption, better economic benefits and the like.

Description

technical field [0001] The present invention is used for dedusting the driving surface of coal mines, and specifically relates to a mining hydraulic dedusting system and a hydraulic dedusting method. Specifically, a hydraulic system is used to drive a hydraulic motor to drive a fan to conduct ventilation through a filter screen and the like to settle the fine dust to the deduster. At the bottom, the fine dust is washed with water to the scraper conveyor, and the dehydrator is connected to the rear. After dehydration, the purified wind is directly discharged into the well. Background technique [0002] During the production process of coal mine excavation, a large amount of coal dust will be generated due to the cutting and excavation of the roadheader. Coal dust is very harmful. After long-term inhalation of coal dust by underground front-line miners, the chances of suffering from respiratory diseases, pneumoconiosis and even lung cancer will be greatly increased, and the vi...

AI Technical Summary

Problems solved by technology

Domestic mine dust control mainly adopts wet dust removal, but wet dust removal efficiency is low, it is difficult to remove underground respirable dust, and it is easy to cause miners to suffer from pneumoconiosis; while an ordinary wet dust collector consumes about 8-10 tons of water per working day, Serious waste of water resources, while drainage is also a big problem
