Abstract
A water mist and foam dust settling device is particularly suitable for treating dust disasters in underground heading faces of mines. Flying dust generated in an excavation process is settled twice by ejecting water mist and foam, dust generating points can be sufficiently covered, and the purpose of reducing dust hazards is achieved. The foam is generated by a foam generator. The water mist and foam dust settling device comprises the foam generator, a water mist generator, connecting pipelines, a nozzle device and a protective disc, and the foam generator and the water mist generator are connected with the nozzle device by the connecting pipelines. The nozzle device and the protective disc are mounted in a front section of a heading machine, and the foam and the water mist are ejected via the nozzle device to suppress the flying dust. The water mist and foam dust settling device has the advantages of simple structure, convenience in use and installation, high dust settling efficiency and the like, and can be widely used for eliminating coal or rock dust generated during drilling operation in coal and mine industries.
Description
Technical field
This patent relates to a kind of water smoke, foam device for reducing dust, is particularly useful for the improvement of driving face dust disaster under the mine.
Background technology
In mine production, mine construction, can produce a large amount of harmfulness dust; Particularly the respirable dust sedimentation of fine particle is slow; Very big to human harm, only announced about 14000 examples of New Development pneumoconiosis in 2010, there are every year 3000 people to die from pneumoconiosis approximately; Bring greatly misery to patient and family, bring the tremendous economic loss also for enterprise and country.In order to prevent dust harzard, the general down employing spray for dust suppression of mine, blower fan dedusting, coal-bed flooding dedusting and measures such as foam dust suppression, dedusting.But because efficiency of dust collection is low, dedusting is not thorough, can not well prevent the generation of dust disaster.
Summary of the invention
The purpose of this patent is the weak point that overcomes prior art, and a kind of device for reducing dust is provided.
Dust is along with necessary distinguished and admirable all tunnels, down-hole and the space of diffusing to of mine ventilation under the mine, and workman's health is worked the mischief, and exists the danger of dust explosion simultaneously.Through ejection water smoke and foam,, reach the purpose that reduces dust harzard with twice sedimentation of airborne dust that mining process produces.Be installed on the spray nozzle device ejection water smoke and the foam of development machine front end, can fully cover the product dirt pits, foam is produced by foam maker.The utlity model has characteristics such as simple in structure, easy to install and use, depositing dust efficient height, can be adaptable across coal, mine industry, the coal dust or the rock dirt that are produced when eliminating bore operation.This device is sent out grow up to be a useful person (2), connection pipeline (3), (4), spray nozzle device (5) and protection disk (6) by foam maker (1), water smoke and is formed; It is characterized in that foam maker (1) sends out grow up to be a useful person (2) and connect spray nozzle device (5) through being connected pipeline (3), (4) with water smoke; Spray nozzle device (5) ejection water smoke and foam fully cover the product dirt pits; Suppress dust from flying, protection disk (6) is arranged outside the spray nozzle device (5).
Description of drawings
In the structure chart of the utility model, Fig. 1 is the front view of this device; Fig. 2 be in Fig. 1 front view the A-A section to view; Fig. 3 be in Fig. 1 front view the B-B section to view; Fig. 4 be in Fig. 1 front view the C-C section to view.
Foam maker among the figure (1), water smoke is sent out grow up to be a useful person (2), connects pipeline (3), (4), spray nozzle device (5), protection disk (6).
The specific embodiment
The utility model discloses a kind of device for reducing dust, this device comprises that foam maker (1), water smoke are sent out grow up to be a useful person (2), connected pipeline (3) (4), spray nozzle device (5) with protect disk (6).Spray nozzle device (5) and protection disk (6) are installed on the development machine front end, and foam maker (1) is sent out grow up to be a useful person (2) and connected spray nozzle device (5) through being connected pipeline (3) (4) with water smoke.Foam and water smoke fully cover and produce dirt pits through spray nozzle device (5) ejection, suppress dust from flying.Spray nozzle device (5) is outer to have protection disk (6), prevents dust plug nozzle device (5).
This apparatus structure is simple, not electricity consumption, and volume is little, and dust suppression efficient is high, and is easy and simple to handle, is prone to apply.Be particularly useful for driving face under the coal mine, reduce face dust concentration, improve working environment.
Claims (2)
1. a water smoke, foam device for reducing dust; It is characterized in that; Send out grow up to be a useful person (2), connection pipeline (3), (4), spray nozzle device (5) and protection disk (6) by foam maker (1), water smoke and form, foam maker (1) is sent out grow up to be a useful person (2) through being connected pipeline (3), (4) connection spray nozzle device (5) with water smoke.
2. a kind of water smoke according to claim 1, foam device for reducing dust is characterized in that spray nozzle device (5) ejection water smoke and foam fully cover the product dirt pits, suppress dust from flying, and protection disk (6) is arranged outside the spray nozzle device (5).
