According to described mine air devider, it is characterized in that, in the stifled wind of described master, in tongue and described auxiliary stifled wind, tongue is hinged and connected with described connecting axle respectively, in main stifled wind, dorsal surface of tongue is fixedly connected with expansion link, and expansion link is circular shape, and in auxiliary stifled wind, dorsal surface of tongue is fixedly connected with sleeve, sleeve is also circular shape, expansion link activity is plugged in sleeve, and sleeve inner is provided with spring, and expansion link free end withstands on spring.
According to described mine air devider, it is characterized in that, in the stifled wind of described master, tongue external surface is fixedly connected with primary seal rubber, and primary seal rubber is corresponding with described main air inlet, in described auxiliary stifled wind, tongue external surface is fixedly connected with auxiliary stripper rubber, and auxiliary stripper rubber is corresponding with described auxiliary air intake.
According to described mine air devider, it is characterized in that, the described housing sidewall inner side at described main air inlet edge is fixedly connected with fixed magnet, and in the stifled wind of described master, lingual margin is fixedly connected with movable magnet, movable magnet and mutual adhesive corresponding with fixed magnet.
The utility model adopts hard material (as iron) to make, simple in structure, sturdy and durable, is realizing under the prerequisite of air devider proper function, has extended the application life of air devider.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing:
1, air outlet; 2, movable magnet; 3, housing; 4, tongue in main stifled wind; 5, fixed magnet; 6, primary seal rubber; 7, main air inlet; 8, connecting axle; 9, auxiliary air intake; 10, auxiliary stripper rubber; 11, tongue in auxiliary stifled wind; 12, sleeve; 13, spring; 14, expansion link.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of mine air devider, comprise housing 3, housing 3 hollows, the sidewall of housing 3 one sides has air outlet 1, upper and lower corresponding main air inlet 7 and the auxiliary air intake 9 of having of sidewall of the opposite side housing 3 relative with air outlet 1, housing 3 inside sidewalls between main air inlet 7 and auxiliary air intake 9 are fixedly connected with connecting axle 8, on connecting axle 8, be hinged with tongue 4 and the interior tongue 11 of auxiliary stifled wind in main stifled wind simultaneously, in main stifled wind, tongue 4 is corresponding with main air inlet 7, in auxiliary stifled wind, tongue 11 is corresponding with auxiliary air intake 9, in main stifled wind, in tongue 4 and auxiliary stifled wind, the angle between tongue 11 is not less than 135 degree.
In the present embodiment, in the stifled wind of described master, in tongue 4 and described auxiliary stifled wind, tongue 11 is hinged and connected with described connecting axle 8 respectively, in main stifled wind, tongue 4 back sides are fixedly connected with expansion link 14, expansion link 14 is circular shape, in auxiliary stifled wind, tongue 11 back sides are fixedly connected with sleeve 12, and sleeve 12 is also circular shape, and expansion link 14 activities are plugged in sleeve 12, sleeve 12 inside are provided with spring 13, and expansion link 14 free ends withstand on spring 13.In the stifled wind of described master, tongue 4 external surfaces are fixedly connected with primary seal rubber 6, and primary seal rubber 6 is corresponding with described main air inlet 7, and in described auxiliary stifled wind, tongue 11 external surfaces are fixedly connected with auxiliary stripper rubber 10, and auxiliary stripper rubber 10 is corresponding with described auxiliary air intake 9.Described housing 3 inside sidewalls at described main air inlet 7 edges are fixedly connected with fixed magnet 5, and in the stifled wind of described master, tongue 4 edges are fixedly connected with movable magnet 2, movable magnet 2 and mutual adhesive corresponding with fixed magnet 5.
The utility model adopts ferrous material to make, use the iron sheet processing welding that 2mm is thick, housing height is 1 meter, width is 0.6 meter, at two air intakes that diameter is 400mm of housing front side processing, be used for connecting master, standby blower fan, in order to prevent that air devider down draught from causing Air escape branch, guarantee the flexible switching of main air inlet and auxiliary air intake, at two air intake places, with the iron sheet that diameter is 400mm, make tongue in stifled wind, when main fan running, in the auxiliary stifled wind of standby fan, tongue is closed, when standby fan running, in the stifled wind of master of main fan, tongue is closed, with this, carry out airflow regulation, rear side at air devider processes air port with the iron sheet that diameter is 400mm equally, be used for connecting air duct.
