Abstract
The utility model discloses a dust-suppressing gas-diluting device with the linkage of wind and water. A water adapter is welded at the middle of a two-inch metal tube with the length of 40mm, a honeycomb-shaped porous plate is welded on the front end of the metal tube, and a wind tube union is welded on the rear end of the metal tube. The utility model can timely eliminate the accumulation of gascaused by the local eddy of the return corner of a working face and poor ventilation, and can dilute gas until the gas concentration is below the safe concentration, so that the gas cannot be accumulated. Wind is organically combined with water, thus realizing the effect of linkage.
Description
Technical field
The utility model relates to the coal mine downhole safety instrument.
Background technology
Contain the mine of gas in some coal seams,, the coal dust gas explosion accident takes place easily in case reach explosion ratio and run into burning things which may cause a fire disaster.At present the method that solves is ventilation dilution and the watering dirt that goes out.Ventilation dilution mainly is to strengthen the down-hole circulation by the main fan exhausting that is positioned in the ventilating shaft, and the watering dirt that goes out mainly is on coal face and coal excavation apparatus sprinkler pipe to be installed.The method of this ventilation watering also leaves the dead angle at the corner place easily, causes gas and coal dust to gather, and influences safety.Also there be not at present to find the device identical with the utility model.
Summary of the invention
The utility model provides a kind of wind and device that supplies water and link of pressing, and reaches the purpose of go out simultaneously dirt and dilution gas.
For achieving the above object, the wind power ganged dirt dilution gas apparatus structure that goes out of the utility model is, at water swivel of the middle part of two cun metal tubes of length 40mm welding, cellular porous plate of front end welding of metal tube, blast connection of rear end welding of metal tube.
The utility model advantage is, during use, the wind power ganged dirt that goes out is diluted the return air corner slide tail place of gas device installation in coal-face and coal excavation apparatus, water swivel directly links to each other with work plane aerosol pump, and the wind joint is connected with the mine compressed air pipeline, and water under high pressure is atomized through porous plate under the high-pressure blast effect, inject directly on corner scope place, and can directly cover the conveyer head, and make the corner place form the water curtain group, avoid the conveyer friction to produce spark.Can in time eliminate work plane return air corner because of local eddy currents and the methane accumulation of ventilating and freely not causing, and gas is diluted to below the safe concentration, gas can't be gathered.Wind and water organically combine, and can realize the effect that links.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Among the figure: 1-metal tube, 2-water swivel, 3-blast connection, the cellular porous plate of 4-.
The specific embodiment
As shown in Figure 1, the utility model is at water swivel 2 of the middle part of two cun metal tubes 1 of length 40mm welding, cellular porous plate 4 of front end welding of metal tube 1, blast connection 3 of rear end welding of metal tube 1.
Claims (1)
1, a kind of wind power ganged dirt dilution gas device that goes out is characterized in that it is at water swivel of the middle part of two cun metal tubes of length 40mm welding, cellular porous plate of front end welding of metal tube, blast connection of rear end welding of metal tube.
