Abstract
The utility model provides an automatic draught distributor for a mine local fan to solve the problem that continuous ventilation is not influenced during the maintenance of the underground local fans of a coal mine. The automatic draught distributor for a mine local fan comprises a forked pipe, and the intersection position in the forked pipe is articulated with a wind screen; and when the automatic draught distributor for a mine local fan is used, two air inlets of the forked pipe are respectively provided with a local fan, and the air outlet of the forked pipe is connected with a fan drum. Normally, one local fan is used for supplying air and the other local fan stops running, and during air supply, the wind screen automatically closes the air inlet at the local fan running-stop side by wind pressure to prevent wind leakage; and when the local fan in running needs stopping for maintenance, the other local fan is turned on, and the wind screen automatically closes the other side of the local fan, so that the continuous air supply is realized.
Description
Technical field:
The utility model relates to ventilation equipment under the coal mine
Background technology:
Driving face all uses secondary fan's (abbreviation portable blower) to ventilate under the coal mine at present, with portable blower be installed in fresh distinguished and admirable in, with air duct fresh air is sent into the construction working face, when portable blower breaks down maintenance or replacing, need stop portable blower work, influence is to the driving face air feed, for underground work bring unfavorable.
Summary of the invention:
The utility model does not influence the continuous ventilating problem for solving when portable blower keeps in repair, and proposes the automatic air devider of a kind of mining portable blower.
The automatic air devider of a kind of mining portable blower, it comprises a bifurcated pipe, the hinged verge board of the infall in bifurcated pipe.
During use, at two air intakes of bifurcated pipe a portable blower is installed respectively, the air outlet of bifurcated pipe connects air duct.A portable blower air feed is often arranged, a shutdown, the air intake that verge board will be shut down side automatically by blast during air feed is closed, and prevents to leak out; When the need shutdown maintenance, open another portable blower, verge board is closed opposite side again automatically, thereby realizes continuous air feed.
Description of drawings:
Fig. 1 is the vertical view of embodiment.
The specific embodiment:
As shown in Figure 1, it comprises bifurcated pipe 3, and bifurcated pipe 3 forms two air intakes, an air outlet, and bore and portable blower and air duct are complementary; Infall in bifurcated pipe 3 is hinged with verge board 2.Tight in order to keep out the wind, when closing, verge board on the contact section, is connected with baffle ring 1.
Claims (2)
1. automatic air devider of mining portable blower, it is characterized in that: it comprises a bifurcated pipe, the hinged verge board of the infall in bifurcated pipe.
2. the automatic air devider of mining portable blower as claimed in claim 1 is characterized in that: on the contact section, be connected with baffle ring when verge board is closed.
