Fully-mechanized excavating machine driver dustproof mask air supply device

Abstract

The invention discloses a fully-mechanized excavating machine driver dustproof mask air supply device. An air barrel, an air nozzle, a filter pipe, an air supply control valve, an air supply hose connector, a hose, a dustproof mask and air barrel connectors are included. The air nozzle is arranged in the air barrel and provided with the air supply hose connector, and the tail end of the air supplyhose connector is connected with the dustproof mask. The initial end of the air barrel is connected to a fresh air fan outside a mine. The air barrel is provided with the air barrel connectors, and the multiple air barrel connectors are arranged along the air barrel at equal interval. The distance between the air nozzle and the air barrel connector in the downwind direction is 200 mm. The air nozzle is provided with the filter pipe, and the air supply hose connector is arranged at the tail end of the filter pipe and matched with the hose. The air supply control valve is arranged on one side of the air supply hose connector. The fully-mechanized excavating machine driver dustproof mask air supply device has the characteristics that dust suction is avoided, and underground operation breathing safety of a fully-mechanized excavating machine driver is guaranteed.

Description

technical field [0001] The invention relates to an air supply device for a dust-proof mask of a fully-mechanized excavator driver, in particular to an air supply device for a dust-proof mask of a fully-mechanized excavator driver capable of avoiding dust inhalation and ensuring breathing safety for the driver of the fully-mechanized excavator during underground operations. Background technique [0002] In the process of coal mining, the dust concentration generated during the operation of the fully mechanized excavation face is relatively high. The current dustproof mask of the fully mechanized excavator driver uses compressed air for air supply, and the dustproof mask is connected to the head-on pressure air pipeline through a thin plastic hose. Although a degreasing device is installed in the air supply section of the dust mask, the degreasing effect is not satisfactory and there is still a peculiar smell, so the use rate of the dust mask is not high; in addition, although ...

Problems solved by technology

[0002] In the process of coal mining, the dust concentration generated during the operation of the fully mechanized excavation face is relatively high. The current dustproof mask of the fully mechanized excavator driver uses compressed air to supply the air, and the dustproof mask is connected to the head-on pressure air pipeline through a thin plastic hose. Although a degreasing device is installed in the air supply section of the dust mask, the degreasing effect is not satisfactory and there is still a peculiar smell, so the use rate of the dust mask is not high; in addition, although the dust blocking rate of the traditional dust mask reaches about 95%, it is harmful to the human body. The most harmful dust (2-3μm in diameter) has a very low filtration rate and still seriously threatens the health of workers
