Abstract
The utility model relates to a dust suppressing device, and particularly to a mining wet dust suppressor which is capable of settling dust, suppressing dust, purifying air and suppressing coal dusts and rock dusts floating in coal mine laneways. The mining wet dust suppressor comprises a pneumatic motor, an impeller, a blade, a shell, a diffuser, an ejector, an air intake regulating valve, a water inflow rate regulating valve, a nozzle and a hub, wherein the structural members including the shell, the diffuser, and the like, of the dust suppressor are all formed by welding low-carbon steel plates; the pneumatic motor is fixed on the shell by a bolt; the impeller is welded together with a side plate of a hollow shaft of the blade through the hub; the impeller is directly linked with an output shaft of the pneumatic motor; an intake flow regulating valve is mounted at the air intake end of the pneumatic motor; the air intake end of the ejector is connected with an air discharging end of the pneumatic motor; and the water inlet of the ejector is connected with the water inflow rate regulating valve. The mining wet dust suppressor disclosed by the utility model is simple in structure, convenient in installment, easy in maintenance, obvious in dust removal and dust suppression effects, low in use cost and low in water consumption, is suitable for high-gas areas, and effectively improves the down-hole working environment.
Description
Technical field
The utility model relates to a kind of dust-arrest device, specifically a kind of can depositing dust, the dirt that goes out, purify air, suppress coal dust floating in the coal mine roadway, the mining wet type dust suppression device of rock dirt.
Background technology
Domestic colliery depositing dust, the dirt that goes out, the facility that purifies air are of a great variety, and structure is different, and effect is generally not satisfactory.At present, what fully mechanized workface generally adopted is the wet dust removal device, and what stope was used is the water curtain method, and wet dust removal apparatus structure volume is big, involves great expense.Water curtain method water droplet is big, and atomizing effect is poor, and water content consumption is big, influences pedestrian and operation.Effectively depositing dust, the dirt that goes out, purify air.
Summary of the invention
The purpose of the utility model provides a kind of ability depositing dust, the dirt that goes out, purifies air, and suppresses coal dust floating in the coal mine roadway, the mining wet type dust suppression device of rock dirt.
The utility model is made up of air motor, impeller, blade, casing, diffuser, injector, air inlet adjustment valve, flow of inlet water control valve, nozzle, wheel hub; Structural members such as the casing diffuser of dust suppression device all are welded with low carbon steel plate; Air motor is fixed by bolts on the casing; Impeller is welded together by wheel hub blade hollow shaft former, and impeller and pneumatic motor output shaft directly connect, and the charge flow rate control valve is installed in the inlet end of air motor; The exhaust end of the air inlet termination air motor of injector, the water inlet of injector connects the flow of inlet water control valve.
The utility model has following advantage compared with prior art:
Simple in structure, easy for installation, safeguard simply, dedusting, the dirt effect of going out are obvious, practical cost is low, water consumption is few, is suitable for high gas zone and uses, and has improved the operating environment of down-hole effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. air motor, 2. impeller, 3. blade, 4. casing, 5. diffuser, 6. injector, 7. charge flow rate control valve, 8. flow of inlet water control valve, 9. nozzle, 10. wheel hub, 11. hollow shafts.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
The utility model is made up of air motor 1, impeller 2, blade 3, casing 4, diffuser 5, injector 6, air inlet adjustment valve 7, flow of inlet water control valve 8, nozzle 9, wheel hub 10; Casing 4 diffusers 5 structural members such as grade all are welded with low carbon steel plate; Air motor 1 is fixed by bolts on the casing 4; Impeller 2 is welded together by wheel hub 10, blade 3, hollow shaft 11, former, and impeller 2 directly connects with air motor 1 output shaft, and charge flow rate control valve 7 is installed in the inlet end of air motor 1; The exhaust end of the air inlet termination air motor 1 of injector 6, the water inlet of injector 6 connects flow of inlet water control valve 8.
The course of work of the utility model is: when starting air motor, compressed air is through air motor, and impeller, blade rotate; The Compressed Gas of getting rid of through motor has got into injector, and the mine dead weight water in the injector is under compressed-air actuated effect, and fully atomizing sprays through nozzle again; Water curtain by the nozzle ejection; Be diffused in the air of big lane through blade, diffuser, increase humidity, the water droplet inertial collision in the grit that makes big lane and the fog and separate and catch.Because the condensation rate of dust suppression device is high, the atomization gas diffusingsurface is big, floating distance, and it is big to catch the dirt area.Can form condensate on the grit surface; The diameter and the wettability of grit have been increased; Be convenient to be caught and condense into larger particles by water droplet and accelerate sedimentation, the charge of water droplet and grit also promotes condensing of grit, has reached depositing dust, the dirt that goes out, the effect that purifies air.
