Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal technology for mining fans, specifically to a dust removal device for mining fans. Background Technology
[0002] Mining fans provide sufficient oxygen and cooling systems for underground coal mining and electrical equipment, maintaining the stability and safety of the entire coal mining production process. They are an indispensable piece of equipment in mining operations. At the same time, in order to reduce dust in mining operations and improve the working environment in the mine tunnels, mining fans often perform dust removal treatment on the air supply.
[0003] In existing dust removal devices for mine fans, most dust removal is achieved through either filters or wet methods. However, both methods have certain drawbacks. Due to the large amount of dust such as coal ash in the mine tunnels, dust removal through filters can easily cause filter blockage, reduce filtration capacity, and require frequent replacement of filter elements, which is very troublesome. On the other hand, wet dust removal can significantly increase the humidity of the supplied air, which can easily lead to excessive humidity in the mine tunnels, affecting the operation of electrical equipment and posing a great danger.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.
[0025] A dust removal device for mining fans, such as Figure 1 , Figure 2 As shown, it specifically includes:
[0026] A washing tank 1 and a trolley 2; the washing tank 1 has a square box structure with a water inlet at the top, a drain pipe 18 at the bottom of the rear side wall, and a valve on the drain pipe 18. A cap 17 is threaded onto the water inlet. The washing tank 1 is filled with clean water (the water level is about half full). An air inlet pipe 4 is formed at the top of the rear side wall, and an air outlet pipe 3 is formed at the top of the front side wall corresponding to the air inlet pipe 4; the trolley 2 is as follows... Figure 2 As shown, it has two pairs of wheels 20 at the bottom and a push rod 19 fixed at the rear. The washing tank 1 is fixed on the trolley 2.
[0027] Air supply structure and air supply structure, such as Figure 4 As shown; the air supply structure includes a blower 5, which is sleeved and fixed inside the air outlet pipe 3. The air supply structure includes an air inlet pipe 4, a make-up air blower 6, an air-gathering funnel 7, an air guide pipe 8, and an exhaust head 9. The make-up air blower 6 is sleeved and fixed inside the air inlet pipe 4. The air-gathering funnel 7 is arranged horizontally with a smaller front and a larger rear, and its rear end is fixed to the make-up air blower 6. The exhaust head 9 is fixed to the bottom surface inside the washing tank 1, and six exhaust ports are evenly arranged circumferentially on the side wall. An air inlet is reserved at the top and connected to the front end of the air-gathering funnel 7 through the air guide pipe 8 (the exhaust head 9 is arranged in the front half of the washing tank 1).
[0028] Humidity regulation structure such as Figure 3 , Figure 5As shown, the system includes an adjustable air duct 11, a partition 15, and a desiccant 12. The adjustable air duct 11 is a circular tube arranged horizontally in the washing tank 1, with its front end connected and fixed to the air inlet pipe 4. The partition 15 is arranged parallel to the adjustable air duct 11 and fixed inside the adjustable air duct 11. The adjustable air duct 11 on both the left and right sides of the partition 15 contains a desiccant 12 and a filler (the filler is located on the right side of the partition 15 to increase the air resistance of the right channel, and its resistance value is similar to that of the desiccant, facilitating the humidification of the supplied air). (The degree is adjusted), the baffle 16 is arranged vertically and fixed in front of the regulating air duct 11. The dry electromagnetic air valve 13 and the wet electromagnetic air valve 14 are respectively set on the baffle 16 on the left and right sides of the partition 15. The dry electromagnetic air valve 13 is set on the partition 15 in front of the desiccant 12, and the wet electromagnetic air valve 14 is set on the partition 15 in front of the filler. After the dry electromagnetic air valve 13 and the wet electromagnetic air valve 14 are opened, the humid air in the water washing tank 1 and the dry air after the desiccant treatment are mixed and sent out by the blower 5.
[0029] It also includes a ventilation riser 10, which is fixed in the middle of the washing tank 1 (the discharge head 9 is set in front of the ventilation riser 1), and the bottom is fitted with the bottom wall of the washing tank 1 with a gap (to keep the water flowing). A circular opening is reserved at the top, and multiple ventilation holes are provided on the left and right sides of the circular opening (to facilitate the movement of gas from the front of the ventilation riser 10 to the rear of the ventilation riser 10). The regulating air duct 11 is sleeved and fixed in the circular opening, and the rear end is set in the rear of the ventilation riser 10.
[0030] In the specific implementation of this embodiment:
[0031] Water is added to the washing tank 1 and closed when the water level is about half full. At this time, the bottom of the ventilation plate 10 is immersed in clean water. After pushing the new model to the designated working position, the supplementary air fan 6 and the blower 5 are started. The dirty air from the outside is sent into the washing tank 1 through the supplementary air fan 6, and then passes through the air-gathering funnel 7, the air guide pipe 8 and the discharge head 9 in sequence before being discharged into the clean water for dust removal and adsorption. Under the action of buoyancy, the clean humid air leaves the clean water and, under the action of the blower 5, passes through the ventilation plate 10 and moves to the rear side of the ventilation plate 10. After being processed by the regulating air duct 11, it is sent into the mine tunnel for oxygen supply and cooling.
[0032] During the air supply process, the dry electromagnetic valve 13 and the wet electromagnetic valve 14 are controlled by the humidity sensor in the mine tunnel. The opening of the dry electromagnetic valve 13 and the wet electromagnetic valve 14 is automatically adjusted according to the specific humidity, thereby changing the ratio of the air volume discharged through the desiccant 12 and the filler, and changing the humidity of the supplied air after mixing, thus regulating the air humidity in the mine tunnel.
[0033] The above has described the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
