Abstract
The utility model provides a dust device in pit, belongs to colliery additional equipment field, including scraper conveyor, and spray pipe, shower nozzle, scraper conveyor install in the colliery in the pit on the face, the spray pipe setting on the wall of scraper conveyor both sides, the spray pipe include tuber pipe and water pipe, the shower nozzle install the lateral wall that passes scraper conveyor on the wall of scraper conveyor's both sides and in having the extroversion, the shower nozzle have a plurality ofly, the shower nozzle install when the face is fill coal, the coal has and effectively to reduce the colliery dust pollution of face in the pit near scraper conveyor's placement, saves the characteristics artifical and water source.
Description
Technical field
The utility model belongs to ancillary service field, colliery, particularly a kind of down-hole device for reducing dust.
Background technology
In the production operation in colliery, down-hole coal excavation work plane is the groundwork place of coal mining coal, the coal of extraction needs to transport away at work plane, scraping plate conveying device is mostly adopted now to carry out first order conveying, namely on face, the coal of extraction is first loaded on drag conveyor, then installing on scraper-trough conveyer i.e. belt conveyor, and be transported to aboveground; Because the coal on getting working face is scattered, and water content is little, from face in the process that drag conveyor is coaling, a large amount of coal dusts can be formed at getting working face, although have spraying dust-proof device at face or tunnel, but the local operator of corresponding face can form dust pollution, work the mischief to the health of operating personnel, in order to reduce dust, only have employing manually to carry out watering operation, labour intensity is large, waste water, dust-laying effect is bad.
Summary of the invention
For the existing underground coal mine getting working face problem that dust is large when loading drag conveyor, the utility model proposes a kind of down-hole device for reducing dust, it is characterized in that: comprise drag conveyor, sparge pipe, shower nozzle; Described drag conveyor is arranged on underground coal mine face; Described sparge pipe is arranged on drag conveyor two side; Described sparge pipe comprises airduct and water pipe; The two side that described shower nozzle is arranged on drag conveyor have outside to inside through the sidewall of drag conveyor; Described shower nozzle has multiple; Described shower nozzle is arranged on face when coalingging, and coal is near the drop point of drag conveyor.
Beneficial effect
The beneficial effects of the utility model are, effectively can reduce the dust pollution of underground coal mine face, save artificial and water source.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
1. drag conveyor, 2. sparge pipe, 3. shower nozzle.
Detailed description of the invention
In order to the technical solution of the utility model is described, now further illustrate detailed description of the invention of the present utility model by reference to the accompanying drawings; As Fig. 1, the drag conveyor selecting the industry general, as drag conveyor 1, attaches it to underground coal mine face; At the dual-side mounting spray head 3 of a near zone of coalingging of drag conveyor 1, bilateral installation is adopted in this example, 6 shower nozzles 3 are installed on every limit, installation site is positioned near drag conveyor 1 side wall lower ends, namely near the position on the conveyer belt top of drag conveyor 1, be evenly arranged, installation interval distance 400 millimeters is adopted in this example, because need to ensure that the spray water that adjacent two shower nozzles 3 spray can cover all coals fallen on drag conveyor 1 conveyer belt, make it moistening and avoid airborne dust to produce in a large number; Select the water pipe of diameter 30 millimeters as water pipe, its water pipe is offered the joint corresponding with each shower nozzle 3, and be connected with the water inlet of each shower nozzle 3; The down-hole compressed air airduct selecting the industry general, installs side by side with water pipe, jointly forms sparge pipe 2 with water pipe, and on airduct, offer the joint corresponding with shower nozzle 3, and be connected with the air intake of shower nozzle 3 respectively; This completes enforcement of the present utility model; During application, open the valve on airduct, compressed air enters shower nozzle 3 from the airduct sparge pipe 2, now open the valve on sparge pipe 2 water pipe, current enter the water inlet of shower nozzle 3, under compressed-air actuated effect, are taken out of and the ejection that nebulizes by water from water pipe, the coal that slurry loads is moistening, avoids a large amount of dust to occur; Owing to adopting compressed air, do not need increase equipment pressurize just can form spraying; Compressed air is the power source that down-hole is commonly used, and draw materials conveniently, and the atomizing effect of water is good, saves water source.
