Abstract

A wet type dust collector for a mining drilling orifice relates to coal mine drilling dust collecting equipment. The wet type dust collector comprises a dust collecting device and a jet flow dust removing device, wherein the back part of the dust collecting device is connected with the jet flow dust removing device via a hose; the jet flow dust removing device is structured by a jet flow disc, an atomizing chamber and a jet flow pipe orderly form front to back; the front part of the jet flow disc is connected with a hose; a steam nozzle is placed in the middle of the jet flow disc; the steam nozzle is provided with a water joint and a steam joint both connected to the jet flow disc; water and steam can be injected to the steam nozzle via the water joint and the steam joint; the back part of the jet flow disc is connected with the atomizing chamber; the atomizing chamber is connected with a jet flow pipe; the tail part of the jet flow pipe is provided with a diversion gate; and behind the diversion gate is provided with a backward water discharging port and a downward sewage discharging port. The beneficial effects of the wet type dust collector for mining drilling orifice are that particles and dust can be separated by the dust collecting device; dust can be absorbed into the jet flow dust removing device via a negative pressure pipeline formed by the steam nozzle; the dust in the jet flow dust removing pipe is fully mixed with mist and then settles in the jet flow dust removing pipe; and orifice dust removal can be achieved.

Description

technical field [0001] The invention relates to the technical field of coal mine machinery, and further relates to coal mine drilling and dust removal equipment, in particular, the coal dust from drilling is sucked into the jet dust removal pipe by the dust collector, mixed with water mist to make the coal dust settle on the inner wall of the jet dust removal pipe, and then is The water is flushed out, so as to achieve the purpose of dust removal. Background technique [0002] Coal is the main energy source in our country, and the safety and efficiency of mines must be ensured during coal mining. Mine gas is one of the main natural disasters in coal mines. In order to reduce the gas content during coal seam mining, advanced coal seam gas discharge has been widely used. The method used is to drill gas drainage holes on the coal wall. Because the coal seam is very dry, coal dust is flying when drilling, and the working environment is smoky. Operators must wear dust masks. E...
