Mining high-pressure local fan

Abstract

A mine-used high-pressure local ventilator, including a collector, an outer casing, an inner casing, an impeller and a guide vane, a fixed platform, and a motor, wherein the impeller and the guide vane include a front impeller, a front guide vane, and a rear impeller 1. Two sets of impellers and guide vanes of the rear guide vane. The positions of the front impeller and the guide vane are the same as those on the existing mine local ventilator. The rear impeller is installed on the extension shaft on the other side of the motor. The outlet side is equipped with a rear guide vane; the pressure of the local fan is increased through the increased rear impeller; the beneficial effect is: the pressure of the fan is high, and the air supply distance of the same diameter air duct can be doubled by the invention, which solves the problem of metal mines. The problem of safe air supply in irregular roadways in mining, and the fan is light in weight and simpler in structure, suitable for underground transfer, and improves the efficiency of the fan.

Description

technical field [0001] The invention relates to a mine fan, in particular to a mine high-pressure local fan. Background technique [0002] At present, one kind of mining fan on the market is a mining local fan (such as figure 1 ), due to the current mining of metal mines, the section of the roadway is relatively small, and the air supply pipes cannot use larger diameter air ducts, which makes it very difficult to supply air safely. The existing mine local fans only have one set The impeller and guide vane, the wind pressure is small, and it is impossible to realize the safe air supply of the non-standard roadway in the mining of metal mines. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a mine high-pressure local ventilator. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a mine-used high-pressure local ventilator, including a...
