[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Please refer to Figure 1-4 The utility model provides a technical solution: an underground mine ventilation device, including a shell 100 installed in an underground mine. The shell 100 is made of stainless steel in this application. An air inlet ring 200 is provided at one end of the shell 100 to facilitate air intake. An air outlet 300 is provided at the other end of the shell 100 to facilitate the connection between the air outlet and the air outlet pipe. Two relatively arranged driving members 400 are provided on both sides of the inside of the shell 100. The driving member 400 can be an ordinary motor, which is connected to the power supply in the underground mine and controlled by an external switch. In actual use, it is selected according to the inner diameter and power of the shell 100. The output ends of the two driving members 400 are respectively installed with a left-handed impeller 500 and a right-handed impeller 600. The left-handed impeller 500 and the right-handed impeller 600 are recommended to be made of aluminum alloy, which is light in weight and reduces energy loss.

[0022] When in use, the two driving members 400 work, and the air in the underground mine enters the outer casing 100 through the air inlet ring 200. The right-handed impeller 600 sucks the wind between the two driving members 400, and then the left-handed impeller 500 discharges the wind between the two driving members 400 through the air outlet 300. The counter-rotating exhaust between the left-handed impeller 500 and the right-handed impeller 600 has a good windproof effect.

[0023] Furthermore, an air guide column 700 and an air separation column 800 are respectively fixed on both sides of the interior of the outer shell 100 at the positions of the left-handed impeller 500 and the right-handed impeller 600. By using the air separation column 800, the air entering from the air inlet circle 200 can be dispersed, and by using the air guide column 700, the exhausted air can rotate along the air guide column 700, thereby achieving permeability.

[0024] Furthermore, the ends of the wind guide column 700 and the wind distribution column 800 are both rounded to reduce the obstruction when the wind contacts, and the wind guide column 700 is in a truncated cone shape.

[0025] When in use, the air guide column 700 is in a frustum shape, so that the discharged air can rotate along the air guide column 700, and the tip is in a triangular shape, so that the discharge is smoother.

[0026] Furthermore, the housing 100 includes an air delivery cover 101 , a lifting ear 102 and a connecting cover 103 . Both sides of the air delivery cover 101 are fixed to the connecting cover 103 by bolts, and the lifting ear 102 is fixed to the outer side of the middle part of the air delivery cover 101 .

[0027] When in use, the use of the lifting ear 102 facilitates the lifting and installation of the entire device, the use of the wind transfer cover 101 facilitates the transmission of wind between the left-handed impeller 500 and the right-handed impeller 600, and the use of the connecting cover 103 facilitates the installation of the air inlet circle 200 and the air outlet 300.

[0028] Furthermore, the wind guide column 700 and the wind distribution column 800 are fixed on the left-handed impeller 500 and the right-handed impeller 600 respectively.

[0029] When in use, the left-handed impeller 500 and the right-handed impeller 600 rotate to respectively drive the air guide column 700 and the air distribution column 800 to rotate, so as to better use the air guide column 700 and the air distribution column 800.

[0030] Furthermore, the air inlet ring 200 is trumpet-shaped, so that the air inlet ring 200 can expand the air intake. The air inlet ring 200 is fixed to one end of the housing 100 by screws.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
