Abstract
The utility model relates to equipment for mines, in particular to a dust removing fan in a coal mine, and solves the problems of complex structure, high processing cost, inconvenience in use and the like existing in the conventional dust removing fan used in the coal mine. The dust removing fan comprises a fan shell and blades which are arranged at one end of the fan shell, and has the innovation points that: the other end of the fan shell is provided with a dust collecting flare opening; a slime water storage funnel which is communicated with the fan shell is arranged below the fan shell; dust trap water curtain generators are arranged at the periphery of the fan shell, are positioned between the dust collecting flare opening and the slime water storage funnel and are connected with high-pressure water pipes; the high-pressure water pipes are provided with valves; a drawing spring is arranged on the lower part in the slime water storage funnel; and an automatic gate is arranged at the lower outlet of the slime water storage funnel. The dust removing fan has a simple structure, a rational design and a good dust removing effect and is easy and convenient to use, can automatically discharge trapped slime water and can be widely applied to dust removal of an excavation working face in the coal mine.
Description
Technical field
The utility model relates to mine equipment, is specially the dedusting fan under a kind of coal mine.
Background technology
Known, getting working face is in the coal cutting process under the coal mine, produce a large amount of coal dusts, severe contamination workman's operating environment, workman healthy caused very big harm, administered coal dust so have only, could create a good operating environment, also can guarantee the safety in production of mine simultaneously to the workman from the source.At present the most frequently used is applicable to that it is dedusting fan that the equipment of dirt is taken out in coal under the coal mine, stone drifting anchor spray face-airing, and it can make dust laden air purify on the spot, and can partly eliminate poisonous and harmful composition in the gas, has effectively improved working environment.But present used dedusting fan complex structure, processing cost height, and use inconvenience.
Summary of the invention
There are problems such as complex structure, processing cost height, use inconvenience in used dedusting fan to the utility model under the existing coal mine in order to solve, and a kind of new dedusting fan is provided.
The utility model is to adopt following technical scheme to realize: dedusting fan, the blade that comprises blower housing and be installed on blower housing one end, innovative point of the present utility model is that the blower housing other end is provided with the control of dust horn mouth, the black water that blower housing below is provided with its perforation stores funnel, the blower housing periphery is also stored to be equipped with between the funnel at control of dust horn mouth and black water and is caught the dirt water screen generator, catch on the dirt water screen generator and be connected with high-pressure water pipe, valve is housed on the high-pressure water pipe.The high-pressure water pipe of catching dirt water screen generator and tunnel is connected, and behind the Open valve, water under high pressure injects catches the cavity of dirt water screen generator, and enters blower fan by the aperture on the Fan casing and form water curtain.
In order to guarantee to catch the dirt effect, the described dirt water screen generator of catching is caught dirt water screen generator and secondary by one-level and is caught the dirt water screen generator and be in series.
In order to make the black water that accumulates in the funnel can reach automatic discharging, described black water is provided with the spring that furthers below storing in the funnel, black water stores the outlet of funnel lower end the automatic gate that is connected with spring one end that furthers is installed, when black water gathers to a certain degree, rely on himself gravity that automatic gate is opened, black water flows out, and automatic gate resets under the effect of the spring that furthers.
Compared with prior art, the utility model is simple in structure, and is reasonable in design, easy to use, good dedusting effect, and the black water of catching can also be reached automatic discharging, can be widely used in the processing of getting working face coal dust under the coal mine.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Among the figure: the 1-blower housing; The 2-blade; 3-control of dust horn mouth; The 4-black water stores funnel; The 5-high-pressure water pipe; The 6-valve; The 7-one-level is caught the dirt water screen generator; The 8-secondary is caught the dirt water screen generator; The 9-spring that furthers; The 10-automatic gate; The 11-aperture.
The specific embodiment
Dedusting fan, as shown in Figure 1, 2, the blade 2 that comprises blower housing 1 and be installed on blower housing one end, blower housing 1 other end is provided with control of dust horn mouth 3, the black water that blower housing below is provided with its perforation stores funnel 4, black water is provided with the spring 9 that furthers below storing in the funnel 4, and black water stores the outlet of funnel lower end the automatic gate 10 that is connected with spring one end that furthers is installed.The blower housing periphery is also stored to be equipped with between the funnel 4 at control of dust horn mouth 3 and black water and is caught the dirt water screen generator, catching the dirt water screen generator catches dirt water screen generator 7 and secondary by one-level and catches dirt water screen generator 8 and be in series, catch and be connected with high-pressure water pipe 5 on the dirt water screen generator, valve 6 is housed on the high-pressure water pipe.
After starting blower fan, the blade rotation produces negative pressure, the coal dust that produces in the coal cutting process is sucked blower fan by the control of dust horn mouth, catching dirt water screen generator, secondary by one-level catches water curtain that the dirt water screen generator produces and coal dust is caught (water under high pressure of catching dirt water screen generator and tunnel closes and connects, behind the Open valve, water under high pressure injects the cavity of catching the dirt water screen generator, and enter blower fan by the aperture on the Fan casing 11 and form water curtain), and formation black water inflow black water stores funnel, and flow into the ditch, tunnel, thereby reach the purpose of dedusting by the dewatering outlet.
