Abstract

The utility model discloses a dustproof device of an underhole coal conveying transfer point. The dustproof device comprises a dustproof shield (2), a rotary sprayer (3) mounted inside the dustproof shield (2) and movable wind blocking curtains (1) fixed on a coal outlet and a coal inlet of the dustproof shield (2), wherein a packed hole signal line (5) is fixed on the inner wall of the dustproof shield (2), and an insulation protective curtain (4) is arranged between the packed hole signal line (5) and the movable wind blocking curtain (1) fixed on the coal inlet of the dustproof shield (2). The dustproof device of the underhole coal conveying transfer point is easy to operate and convenient to use and maintain, and is a totally enclosed dustproof device. When the dustproof device is used in the underhole coal conveying transfer point, dust trapping effect of transfer spray and dust reducing efficiency of the transfer point can be improved.

Description

Underground hauling of coal transfer point dust guard

Technical field

The utility model relates to a kind of dust guard, is specifically related to a kind of dust guard that is used for the underground hauling of coal transfer point.

Background technology

Produce a large amount of dust in Coal Production and the transportation, it not only threatens mine safety, and it is healthy directly to influence the worker.The down-hole dust results from the mining work, and usually all the getting working face that focuses on of dust suppression in mine work, but coal also can produce a large amount of dust in the reprinting transportation of down-hole.Just adhere to the number of fine dust on the broken coal cinder that transports from getting working face, these coal cinders are in transport process, because collision and wind each other, the fine dusts of adhesion can become the dust that swims gradually, in underground air, spreads the severe contamination air.

Traditional approach is handled the coal dust of transfer point and is eliminated by reprinting spraying, and its coal dust is wayward.Coal dust flies upward in the tunnel, not only endangers healthyly, is prone to cause the operating personnel to suffer from pneumoconiosis, and operation place visibility is reduced, and influences job safety; Causing coal dust to be piled up when serious, also safety management is formed direct threats, always is stubborn problem in the field control under the coal mine.This shows that reprinting the dustproof of transportation system is the very important important component part of mine synthesis dust prevention, the use of transfer point spraying also just seems particularly important with management.

The utility model content

The technical problem that the utility model will solve provide a kind of reasonable in design, can effectively control the dust guard that is used for the underground hauling of coal transfer point that coal dust flies upward.

For solving the problems of the technologies described above; The underground hauling of coal transfer point dust guard of the utility model; Comprise dust cover, be installed in the rotary sprayer in the dust cover and be fixed on the movable screen of dust cover coal outlet and coal feed point; It is characterized in that: meet the eye on every side on the inwall that holding wire is fixed on dust cover, meet the eye on every side holding wire and be fixed between the movable screen of dust cover coal feed point and be provided with the insulation blocking curtain.

Dust Bian made with iron, hairdryer preclude the use of isolation protection curtain cloth.

Compared with prior art, the beneficial effect that the utlity model has is:

1, the utility model is totally enclosed dust guard; When being used for the underground hauling of coal transfer point, can effectively control coal dust and fly upward, reduce the coal dust range of scatter; The coal dust rain that drops on the belt plays the effect of moistening coal stream; Make the coal dust can not secondary fly-up, dustproof spraying have obtained maximum using, has improved the depositing dust efficient of catching dirt effect and transfer point of reprinting spraying.

2, the utility model is reasonable in design, simple to operate, use is easy to maintenance.Preclude the use of movable windshield curtain old belt made of metal dust preclude the use made of isolation hairdryer cloth curtain preclude the use made of inexpensive conducive to the promotion.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

Fig. 1 is the structural representation of the utility model underground hauling of coal transfer point dust guard.

The specific embodiment

As shown in Figure 1; Underground hauling of coal transfer point dust guard; Comprise dust cover 2, be installed in the rotary sprayer 3 in the dust cover 2 and be fixed on the movable screen 1 of dust cover 2 coal outlets and coal feed point; Meet the eye on every side on the inwall that holding wire 5 is fixed on dust cover 2, meet the eye on every side holding wire 5 and be fixed between the movable screen 1 of dust cover 2 coal feed points and be provided with insulation blocking curtain 4.

Dust cover 2 forms confined space with movable screen 1, and the coal dust that transfer point is kicked up is controlled in the dust cover 2, and coal dust can not be flown upward everywhere; The rotary sprayer 3 that is installed in the dust cover 2 at the uniform velocity rotates water spray in use; Dirt pits is produced in the full face from top to down covering of the water curtain that forms; Can effectively coal dust and water, mixing be formed dust-shower; Drop on and make coal stream be moisture state on the belt, can prevent that coal dust from receiving in transportation to produce secondary fly-up when vibrating.The holding wires 5 of meeting the eye on every side that are installed in the dust cover 2 are not influenced by spraying, and when the coal that breaks down at conveyor was piled up, coal piling held up insulation blocking curtain 4, touches when meeting the eye on every side holding wire 5, meet the eye on every side signal and move at once and stop to transport coal.

Claims

1. underground hauling of coal transfer point dust guard; Comprise dust cover (2), be installed in the rotary sprayer (3) in the dust cover (2) and be fixed on the movable screen (1) of dust cover (2) coal outlet and coal feed point; It is characterized in that: meet the eye on every side holding wire (5) and be fixed on the inwall of dust cover (2), meet the eye on every side holding wire (5) and be fixed between the movable screen (1) of dust cover (2) coal feed point and be provided with insulation blocking curtain (4).

(2) as claimed in claim 1, wherein the loading point of coal mine dust, characterized in that: said dust cover (2) preclude the use made of iron, the isolation protection curtain (4) preclude the use of duct cloth percent.
