Description

Technical Field

[0001] The utility model relates to the technical field of fan diffuser towers, and particularly relates to a mine fan diffuser tower. Background Technique

[0002] The mine fan diffuser tower is a part of the mine fan system. Its main function is to guide and diffuse the air flow generated by the fan to ensure the air circulation and waste gas emission in the mine. The diffuser tower body is usually made of metal or strong and durable materials, and is internally provided with structures such as guide plates to optimize the air flow. Through reasonable guide plate design and air flow channels, uniform diffusion of the air flow is achieved, and the ventilation efficiency is improved. Its design takes into account the principles of air flow dynamics to ensure that the air flow can smoothly enter, pass through, and discharge from the diffuser tower. Some diffuser towers are designed with noise reduction structures, such as using acoustic materials or setting sound insulation facilities, to reduce the noise generated during the operation of the fan. Strong materials and reasonable structural design are adopted to ensure the stability and durability of the diffuser tower during long-term use.

[0003] At present, in the prior art, for most mine fan diffuser towers, during operation, their diffuser plates are often fixed. Therefore, when high-speed air passes through the diffuser tower and the diffuser plate diffuses the high-speed air, the diffusion angle is a fixed angle and cannot change the angle of the diffuser plate according to the air speed, resulting in a decrease in the use efficiency of the device. In view of this, we propose a mine fan diffuser tower. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a mine fan diffuser tower that can solve the problems raised in the above technical background.

[0005] To achieve the above purpose, a mine fan diffuser tower proposed by the utility model includes a device main body, and a diffusion structure is arranged on the inner wall of the device main body. The diffusion structure includes:

[0006] A rotating shaft is arranged on the inner wall of the device main body. The surface of the rotating shaft is fixedly connected to the surface of a diffuser plate. A limiting column is fixedly connected to the upper surface of the diffuser plate, and a rotating shaft is rotatably connected to the inner wall of the diffuser plate.

[0007] Preferably, a dust-catching net is fixedly connected to the upper surface of the rotating shaft, and a synchronous rod is rotatably connected to the upper surface of the dust-catching net. There are two synchronous rods in total, and the two synchronous rods are respectively arranged at both ends of the upper surface of the dust-catching net.

[0008] Preferably, a limiting rod is fixedly connected to the surface of the rotating shaft. One end of the limiting rod is fixedly connected to the surface of a reed, and the other end of the reed is fixedly connected to the surface of a limiting block. The limiting block is arranged on the surface of the device main body.

[0009] Preferably, there are two sets of the diffusion structures, and the dust screens arranged inside the two sets of diffusion structures are staggered with each other.

[0010] Preferably, the device main body includes a diffusion tower housing, a bracket is fixedly connected to the surface of the diffusion tower housing, a moving roller is rotatably connected to the inner wall of the bracket, and a universal wheel is fixedly connected to the bottom surface of the diffusion tower housing.

[0011] Preferably, the inner wall of the diffusion tower housing is rotatably connected to the surface of the rotating shaft, and a limiting block is fixedly connected to the surface of the diffusion tower housing.

[0012] The utility model provides a mine fan diffusion tower. It has the following beneficial effects:

[0013] In this mine fan diffusion tower, through the arranged diffusion structure, when the fan draws air into the diffusion tower housing, the front end of the diffusion plate is streamlined, while the rear end of the diffusion plate does not have an anti-turbulence structure. Therefore, when the wind passes through the diffusion plate, the wind speed will be faster at the front section of the diffusion plate, and a larger wake will be generated at the rear end, causing the diffusion plate to vibrate at a high speed, thereby further improving the diffusion effect of the diffusion plate. The dust screen arranged on the diffusion plate is blown by the wind, causing the dust screen to swing, and then swing synchronously through the synchronizing rod. The dust screens of the two sets of diffusion structures are staggered with each other, so as to further enhance the diffusion effect and capture particulate pollutants in the wind.
