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 [0001] The invention relates to an air supply device, in particular to an air supply device for mines. Background technique [0002] Known: because the depth of the mine is not ventilated, it is necessary to send air through the distribution device, thereby avoiding the lack of oxygen of the workers working in the depth of the mine. Especially the mines of coal mines need to be ventilated so as to avoid gas accumulation and cause gas explosions. [0003] In the existing air supply device, when there is air leakage in the air duct, it is difficult to detect, which will lead to the inability to supply air in the depths of the mine, resulting in dangerous situations. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an air supply device for a mine that can ensure the air supply deep in the mine. [0005] The technical solution adopted by the present invention to solve the technical problem is: the ai...
