Abstract
The invention discloses an air supply device capable of ensuring ventilation in a deep pit for mines. The air supply device for mines comprises a first fan, a second fan, a first air pipe and a second air pipe; an end of the first air pipe is communicated with the first fan, the other end is the outlet; one end of the second air pipe is communicated with the second fan, the other end is sealed; several connection pipes are provided between the first air pipe and the second air pipe; on the connection pipes there are single direction air pressure switches which only allow the air to flow from the second air pipe to the first air pipe. The intersection between the second fan and the second air pipe is provided with a pressure detector. The application of the air supply device for mines can ensure the good ventilation in the mine and guarantee the safety of mining operations.
Description
Technical field
The present invention relates to a kind of air supply device, especially a kind of air supply device for mine.
Background technology
Known: deep in mine due to stuffy it is therefore desirable to be blown by sending separating device, thus avoiding mine deep
Workman's anoxia of place's work.The mine in especially colliery, needs to be aerated, thus avoiding gas to accumulate, to cause gas explosion.
Existing air supply device when airduct occurring leaking out, be difficult to discover thus can lead to deep in mine cannot air feed, make
Become the generation of dangerous situation.
Content of the invention
The technical problem to be solved is to provide a kind of confession for mine that ensure that deep in mine air feed
Wind apparatus.
The technical solution adopted for the present invention to solve the technical problems is: for the air supply device of mine, including the first wind
Machine, the second blower fan, the first airduct and the second airduct；Described first airduct one end is connected with the first blower fan, and the other end is opening
End；Described second airduct one end is connected with the second blower fan, and the other end is sealed end；Set between described first airduct and the second airduct
It is equipped with some communicating pipes, described communicating pipe is provided with and is switched from the air pressure individual event that the second airduct turns on to the first airduct；Described
The junction of the second blower fan and the second airduct is provided with pressure-detecting device.
Further, described communicating pipe is uniformly distributed on the first airduct and the second airduct.
Preferably, the spacing between two neighboring communicating pipe is 2 to 10m.
The invention has the beneficial effects as follows: the air supply device for mine of the present invention, including the first blower fan, the second wind
Machine, the first airduct and the second airduct；It is provided with some communicating pipes, described company between described first airduct and the second airduct simultaneously
The air pressure individual event valve being turned on to the first airduct from the second airduct is provided with siphunculus.Therefore during the first airduct air feed,
If leakage in certain position of the first airduct, the second airduct can be turned on the first airduct, the wind sent into by the second airduct
Supplement the air quantity that the first airduct is missed, so that the wind energy in the first airduct is enough sent to deep in mine.Colleague passes through well head
Pressure-detecting device can in time detection whether leak out to the first airduct such that it is able to timely carry out Inspection and maintenance；Therefore
The air supply device for mine described in this practicality, ensure that the air feed of mine, improves the safety of mine operation.
Brief description
Fig. 1 is the structure chart of the air supply device being used for mine in the embodiment of the present invention；
In figure indicates: 1- first blower fan, 2- second blower fan, 3- first airduct, 4- second airduct, 5- communicating pipe, 6- air pressure
Individual event valve.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
As shown in figure 1, the air supply device for mine of the present invention, including the first blower fan 1, the second blower fan 2, first
Airduct 3 and the second airduct 4；Described first airduct 3 one end is connected with the first blower fan 1, and the other end is opening；Described second wind
Pipe 4 one end is connected with the second blower fan 2, and the other end is sealed end；It is provided with some between described first airduct 3 and the second airduct 4
Communicating pipe 5, be provided with the air pressure individual event valve 6 being turned on from the second airduct 4 described communicating pipe 5 to the first airduct；Described second wind
The junction of machine 2 and the second airduct 4 is provided with pressure-detecting device.
Air supply device for mine of the present invention, including the first blower fan 1, the second blower fan 2, the first airduct 3 and
Second airduct 4；It is provided with some communicating pipes 5 between described first airduct 3 and the second airduct 4 simultaneously, described communicating pipe 5 is arranged
There is the air pressure individual event valve 6 being turned on from the second airduct 4 to the first airduct 3.Therefore during the first airduct air feed, if first
Leakage in certain position of airduct, and the second airduct can be turned on the first airduct, supplements first by the wind that the second airduct is sent into
The air quantity that airduct is missed, so that the wind energy in the first airduct is enough sent to deep in mine.The pressure inspection by well head for the colleague
Survey whether device can in time detection leak out to the first airduct such that it is able to timely carry out Inspection and maintenance；Therefore this practicality
The described air supply device for mine, ensure that the air feed of mine, improves the safety of mine operation.
When leaking out in order to more accurately timely give the first airduct 3, carry out mending wind.Further, described company
Siphunculus 5 is uniformly distributed on the first airduct 3 and the second airduct 4.Specifically, the spacing between two neighboring communicating pipe 5 be 2 to
10m.
