Mining roadway pneumatic dust-removing device

Abstract

The invention discloses a mining roadway pneumatic dust-removing device, which comprises at least one group of device, wherein each group of device is formed by connecting a cylindrical base with air outlet frames on the two sides; a base air inlet at the bottom of the base is connected with one end of an air inlet pipe through a tee joint at the bottom of the base; the other end of the air inlet pipe is connected with a roadway main pressure ventilation pipe; a base air outlet at the bottom of the base is connected with one end of an exhaust pipe; the other end of the exhaust pipe is connected with the first end of the tee joint; the second end of the tee joint is connected with one end of a water inlet pipe; the third end of the tee joint is connected with an atomizing water curtain pipe; a power blade and a turbine pressurizing blade are arranged in the base; turbine pressurizing blade air inlet holes are formed in a shell on the two sides of the base; an air outlet frame air outlet is formed in the outer sides of the air outlet frames; and a dust-removing net is arranged on the back sides of the air outlet frame air outlet. The mining roadway pneumatic dust-removing device solves the problems that the existing dust-removing device has a poor dust-removing effect, is not safe and is complex in operation.

Description

technical field [0001] The invention relates to a pneumatic dust removal device, in particular to a mine roadway pneumatic dust removal device. Background technique [0002] Coal mine dust refers to the fine particles of rock and coal that are produced in the production process of coal mine development, excavation, mining and lifting transportation, and can be suspended in the air for a long time, also referred to as mine dust. The hazards of coal mine dust are mainly manifested in: spontaneous combustion and explosion of coal dust, occupational hazards, reduced visibility in the workplace, and accelerated mechanical wear. Existing dust removal methods include: injecting water into the coal seam in the mining face, spraying water to reduce dust, establishing a reasonable ventilation and dust removal system, improving and strict inspection management system, personal protection, etc. Existing dust removal methods generally use traditional fans. Traditional fans need to drive...

AI Technical Summary

Problems solved by technology

Existing dust removal methods generally use traditional fans. Traditional fans need to drive the blades to rotate through the power supply fan. On the one hand, cables need to be laid, and the operation and maintenance are more complicated, which increases the cost. On the other hand, it will generate large noise and affect on-site work. Hearing of personnel; traditional fans use blades to cut the wind and push the airflow by cutting the air. When this airflow blows to the human body, it will produce a dramatic wind impact, which is unstable and poses a great safety hazard
