Abstract

An air splitting device of partial ventilation system mainly solves the technology problem of the present fan having difficulty in solving the air splitting of switch. The key technical scheme points are that a duck outlet is connected with the lower connected spot of left and right air-intake pipes which are communicated each other and the upper part of the lower connected spot of which is hinged with a partial air brake. The lower parts of the left and right air-stake pipes corresponding to the upper part of the connected spot of the duct outlet are solidly connected with the inner shield ring of the air passage matching to the partial air brake and with a sealing ring solidly connected with the lower side through the air splitting device. Solving the problem of partial ventilation of switch of the fan in a more simple way, the air splitting device not only saves the costs and has a good air splitting effects but also meets the requirements of double machine working simultaneously, widely used in the partial ventilation system in coal mine.

Description

Local ventilation system divides wind apparatus

Technical field

The utility model relates to a kind of branch wind apparatus that is used for the mine local ventilation system.

Background technology

At present, in the local ventilation system of mine, each work plane requires to be equipped with two boosters, a job, and one is standby.And the air chimney of common ventilation fan all is to establish one's own system separately, needs to control two ventilation fans separately respectively, the branch wind problem when being difficult to solve ventilation fan and switching.

Summary of the invention

The purpose of this utility model provides a kind of two-shipper can realize that blower fan switches the local ventilation system of branch wind and divide wind apparatus when in parallel smoothly.

The technical scheme that its technical problem that solves the utility model adopts is: bottom connection place at left blast pipe 5 and right blast pipe 6 picks out airduct 4, left side blast pipe 5, right blast pipe 6 and discharge pipe 4 are interconnected, the upper articulation of bottom connection place of a left side blast pipe 5 and right blast pipe 6 divides air lock 1, the connection place top of the corresponding discharge pipe 4 in the bottom of left blast pipe 5 and right blast pipe 6 connect firmly respectively with the air channel of dividing air lock 1 to be complementary in ring washer 2.

Ring washer 2 downsides connect firmly sealing ring 3 in the air channel that the utility model also can connect firmly in the bottom of left blast pipe 5 and right blast pipe 6.

The beneficial effects of the utility model are: the branch wind problem when it adopts comparatively simple mode to solve blower fan to switch, not only save cost, and to divide wind effective, and can satisfy two-shipper requirements of one's work simultaneously, it can be widely used in the mine local ventilation system.

The specific embodiment

Embodiment 1, pick out airduct 4 at the utility model in bottom connection place of left blast pipe 5 and right blast pipe 6, left side blast pipe 5, right blast pipe 6 and discharge pipe 4 are interconnected, the upper articulation of bottom connection place of a left side blast pipe 5 and right blast pipe 6 divides air lock 1, the connection place top of the corresponding discharge pipe 4 in the bottom of left blast pipe 5 and right blast pipe 6 connect firmly respectively with the air channel of dividing air lock 1 to be complementary in ring washer 2.The utility model in use, at the air intake of blast pipe 5 and the air intake place of blast pipe 6 two boosters are housed respectively, when the blower fan at the air intake place of the blower fan work at the air intake place that is installed in blast pipe 5, blast pipe 6 stops, because the stream pressure effects in the blast pipe 5 make branch air lock 1 be pushed to that ring washer 2 places block blast pipe 6 in the air channel of blast pipe 6 bottoms, air-flow is from discharge pipe 4 discharges.Blower fan when the air intake place that is installed in blast pipe 5 stops, the blower fan at the air intake place of blast pipe 6 when work, because the stream pressure effects in the blast pipe 6 make branch air lock 1 be pushed to that the ring washer place blocks blast pipe 5 in the air channel of blast pipe 5 bottoms, air-flow is from discharge pipe 4 discharges.When the blower fan at the air intake place of the blower fan at the air intake place that is installed in blast pipe 5 and blast pipe 6 is worked simultaneously, because the stream pressure in blast pipe 5 and the blast pipe 6 quite makes branch air lock 1 be pushed to blast pipe 6 and blast pipe 5 lower central, then the air-flow of blast pipe 6 and blast pipe 5 all can be discharged from discharge pipe 4.Consult Fig. 1 and Fig. 2.

Embodiment 2, and ring washer 2 downsides connect firmly sealing ring 3 in the air channel that the utility model also can connect firmly in the bottom of left blast pipe 5 and right blast pipe 6, rely on stream pressure to make the rubber layer compression seal of sealing ring 3, can strengthen sealing performance effectively, thereby prevent to leak out.Consult Fig. 1 and Fig. 2, all the other are with embodiment 1.

Claims (2)

1, a kind of local ventilation system divides wind apparatus, it is characterized in that: bottom connection place at left blast pipe (5) and right blast pipe (6) picks out airduct (4), left side blast pipe (5), right blast pipe (6) and discharge pipe (4) are interconnected, the upper articulation of bottom connection place of left side blast pipe (5) and right blast pipe (6) divides air lock (1), and the connection place top of the corresponding discharge pipe in the bottom of left blast pipe (5) and right blast pipe (6) (4) connects firmly respectively and divides ring washer (2) in the air lock air channel that (1) is complementary.

2, local ventilation system according to claim 1 divides wind apparatus, it is characterized in that: ring washer (2) downside connects firmly sealing ring (3) in the air channel that the bottom of left blast pipe (5) and right blast pipe (6) connects firmly.
