Description

Technical Field

[0001] The utility model relates to the technical field of mine ventilation devices, and specifically relates to a mine ventilation device with a filtering structure. Background Technique

[0002] A mine is the main place for mining operations, including excavations formed by mining, transportation channels and auxiliary facilities. Mines with excavations exposed on the surface are called open-pit mines, and mines with excavations underground are called underground mines. Generally, there are mine holes during mining, and workers carry out mining in the mine holes. Since the air in the mine holes is not circulating, no fresh air enters the mine holes, and a ventilation device is needed to transmit fresh air from the outside to the inside of the mine holes.

[0003] However, it still has some disadvantages. For example, due to the uneven road surface in the mine hole, when the ventilation device is in use, the device is not placed stably enough, causing the device to shake. Generally, there is a filter frame at the air inlet of the ventilation device, which is not easy to disassemble and can only perform preliminary filtering, so that impurities will be discharged together when the air is discharged, which is rather inconvenient.

[0004] To solve the above problems, a mine ventilation device with a filtering structure is proposed in this application. Content of the Utility Model

[0025] Working principle:

[0026] When a mine ventilation device with a filtering structure is in use, the device is moved into the mine tunnel. The anti-slip support plate 4 is moved downward by the electric telescopic rod 3 provided to contact the ground. The device is supported by four groups of anti-slip support plates 4 to improve the stability of the device and make it not easy to shake. After the device is placed stably, the air extraction fan 9 is started to make the fan work. The air in the mine tunnel enters the air inlet pipe 6 through the first filter frame 7. The first filter frame 7 preliminarily filters the impurities in the air. The air enters the interior of the device main body 5. The water in the water storage tank 11 is conveyed into the water pipe 13 by the water pump 12. The water is sprayed out in the form of a spray through the spray head 15. The spray performs dust suppression treatment on the impurities in the air for further dust removal. The impurities fall onto the second filter frame 18 for collection. The air is discharged through the air outlet pipe 8 to complete the ventilation process. When installing the first filter frame 7, the limit sliding blocks 21 on both sides of the first filter frame 7 are slid into the U-shaped block 19 through the U-shaped block 19 and the card slot 20 provided. The first filter frame 7 is fixed inside the air inlet pipe 6 through the clamping connection between the triangular clamping block 22 and the card slot 20, which facilitates the installation and disassembly of the first filter frame 7.
