Abstract
The utility model provides a dust device's shower nozzle in pit, belongs to colliery additional equipment field, including the water inlet, and fog nozzle, air intake, the water inlet setting at the shower nozzle lower extreme, and advance water piping connection to it is perpendicular with the fog nozzle jet direction, the fog nozzle setting at the tip of shower nozzle, there is the toper orifice inside, the air intake setting at the rear of fog nozzle, the same with the fog nozzle jet direction, air intake and compressed air pipe say and be connected to have and effectively to reduce the colliery dust pollution of face in the pit, the characteristics of saving manual work and water source.
Description
Technical field
The utility model belongs to ancillary service field, colliery, particularly the shower nozzle of 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.
Described shower nozzle comprises water inlet, spray nozzle, air intake; Described water inlet is arranged on shower nozzle lower end, is connected with water inlet pipe, and vertical with spray nozzle jet direction; Described spray nozzle is arranged on the end of shower nozzle, and there is taper spray orifice inside; Described air intake is arranged on the rear of spray nozzle, identical with spray nozzle jet direction; Described air intake is connected with compressed air piping.
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.
Fig. 2 is structural representation of the present utility model
31. water inlets, 32. spray nozzles, 33. air intakes.
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 31 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 is connected with the air intake 33 of shower nozzle 3 respectively; This completes enforcement of the present utility model; During application, open the valve on airduct, compressed air enters the air intake 33 of shower nozzle 3 from the airduct sparge pipe 2, now open the valve on sparge pipe 2 water pipe, current enter the water inlet 31 of shower nozzle 3, under compressed-air actuated airflow function, water is taken out of from water inlet 31 and nebulized spray from spray nozzle 32 endoporus together, by moistening for the coal loaded, a large amount of dust is avoided 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.
