Problems solved by technology

These dusts are mixed with the air and are mainly distributed in the air of the working environment in the form of aerosols, resulting in poor air quality and harsh working environment conditions.
At the same time, due to the inhalation of a large amount of coal (rock) dust by the operator, it is easy to cause dust (silicon) lung disease, which seriously affects the health of the operator.
At present, the commonly used method is to use a spray dust suppression device inside and outside the roadheader to spray water to reduce dust. The dust reduction effect is limited, and it is easy to cause water accumulation in the working environment and affect the normal operation of the unit. The use effect is not very ideal.

Abstract

The invention discloses a dust removing method and a device of cantilever-type comprehensive mechanized development machine; limited sealing space is formed among the external space of the cutting head of the development machine, the development machine body and the coal rock body; the dust powder produced in the process of cutting and smashing the coal rock through the cutting head of the development machine is sealed in the sealing space; the dust powder in the sealing space is removed through the spraying dust removing device; the dust powder in the sealing space is pumped out through the dust removing fan and purified. The invention can greatly reduce the dust powder produced in the cutting process of the development machine, prevent the dust powder dispersing in the working environment and effectively intercept the dust powder flying so as to purify the air and prevent the operator suffering from pneumoconiosis. The device has higher economic and social benefits.

Description

technical field [0001] The invention relates to a dust removal method and a dust removal device, in particular to a dust removal method and a dust removal device of a cantilever type comprehensive mechanized roadheader. Background technique [0002] During the cutting process of the cantilever comprehensive mechanized roadheader, a large amount of coal and rock dust is produced because the coal rock mass is cut and crushed by the cutting head. These dusts are mixed with the air and are mainly distributed in the air of the working environment in the form of aerosols, resulting in poor air quality and harsh working environment conditions. At the same time, due to inhalation of a large amount of coal (rock) dust, operators are prone to dust (silicon) lung disease, which seriously affects the health of operators. At present, the commonly used method is to use spray dust suppression devices inside and outside the roadheader to spray water to reduce dust. The dust reduction effec...
