Embodiment Construction

[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] See figure 1 , figure 2 , the present invention includes a casing 3, a shaft 6, an air inlet pipe 4 connected to the casing 3 and an air outlet pipe 2, the shaft 6 is fixedly connected to the impeller 1, and the impeller 1 is placed in the casing 3 , the shaft 6 is fixedly connected to the front guide 5, the front guide 5 is placed at the mouth of the air inlet pipe 4, and the guide 5 helps the air to enter the air inlet pipe 4. Since the casing 3 is a spiral structure, The negative pressure inside the ventilator is further increased, which is more conducive to the entry of air. The air inlet pipe 4 and the air outlet pipe 2 are both tapered diffusion structures, which enhance the circulation of air.

[0014] The invention has the advantages of simple structure, good ventilation effect, low energy consumption, small volume and conv...

Abstract

The invention relates to a centrifugal mine ventilator. The centrifugal mine ventilator is characterized by comprising a crankshaft, a case, an air inlet pipe and an air outlet pipe, wherein the air inlet pipe and the air outlet pipe are connected with the case, the crankshaft is fixedly connected with an impeller, the impeller is arranged in the case, the crankshaft is fixedly connected with a front guide device, and the front guide device is arranged on an opening of the air inlet pipe. Compared with a traditional centrifugal mine ventilator device, the centrifugal mine ventilator has the advantages of being simple in structure, good in ventilation effect, low in energy consumption, small in size and convenient to convey and operate.

Description

Technical field: [0001] The invention relates to the field of mining equipment, in particular to centrifugal mine ventilator equipment. Background technique: [0002] Under the coal mine, due to the impact of gas gushing, coal dust flying, personnel breathing, and decay of pit logs, harmful and toxic gases continue to increase; at the same time, as the depth of the well increases, the underground temperature also rises. Therefore, underground staff working in this environment for a long time will not only affect their health, but even suffocate them. Especially when the content of methane and coal dust in the air exceeds the specified value, it may cause a gas and coal dust explosion with serious consequences. In order to ensure the health and safe production of underground workers, it is necessary to continuously communicate the dirty air in underground roadways and working faces with the fresh air on the ground, and use centrifugal mine ventilators to improve working cond...
