specific Embodiment

[0017] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the airtight dust removal device at the coal mine transfer point includes a dust cover 01, a dust spray nozzle 02, a sealing cover 03, a dust shield 04, a U-shaped lock 05, and the like.

[0018] It is used for the airtight dust removal device of the transfer point of the fully mechanized excavation face of the coal mine. When in use, the dust cover 01, the dust suppression spray nozzle 02, the sealing cover 03, and the dust shield 04 are fixed on the carrier of the transfer machine and the steel belt conveyor through the U-shaped lock 05. On the shelf, the dust sealing of the transfer point of the fully mechanized excavation face of the coal mine can be completed. During the process of transporting coal at the reloading point, the dust cover 01 and the sealing cover 03 control the coal dust raised at the reloading point in the cover, so that the coal dust cannot fly around and be brought into the wind cur...

Abstract

The invention discloses an airtight dust collection device for use on a transfer point of a coal mine fully-mechanized excavating surface. The airtight dust collection device comprises a sealing cover, wherein the front wall of the sealing cover extends forwards from top to bottom in an arc form; the upper part of the sealing cover is connected with a dust-proof cover; a dust settling spray nozzle is arranged on the inner top wall of the dust-proof cover; a dust-blocking plate is arranged in the dust-proof cover; the upper edge of the dust-blocking plate is hinged to the top wall of the dust-proof cover; and the lower edge of the side wall of the sealing cover and the lower edge of the side wall of the dust-proof cover are provided with U-shaped lock catches respectively. In the process of transporting coal on the transfer point, coal dust raised on the transfer point is controlled in the covers by using the dust-proof cover and the sealing cover, so that the coal dust generated on the transfer point is controlled in an airtight space effectively, and airtight dust settling is performed.

Description

technical field [0001] The invention relates to an auxiliary tool for coal mine transportation, in particular to an airtight dust removal device for a transfer point of a coal mine fully mechanized excavation face. Background technique [0002] With the improvement of mechanization and automation of coal mines, the amount of dust in the air in comprehensive tunneling roadways has increased significantly. The increase in coal dust concentration not only affects the health of miners, but also deteriorates the working environment and causes potential coal dust explosion accidents. The main dust-producing point in the fully mechanized roadway is the excavation head, but a large amount of dust is also generated at the transfer point. The main reason is that there is a drop of about 0.5 meters between the transfer machine and the steel belt conveyor, and the coal falling from the transfer machine Falling and falling onto the belt conveyor breaks up the fine dust in the coal stream...
