[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-4The utility model provides a technical solution: a mine ventilation and dust removal device, including a dust collecting box 1, a fan is installed on the outside of the dust collecting box 1, an air inlet 2 is provided on the outside of the front end of the dust collecting box 1, a filter 3 is installed inside the air inlet 2, and a pre-treatment mechanism 4 is provided on both sides of the air inlet 2. The pre-treatment mechanism 4 includes a support plate 41, an elastic telescopic shaft 42 and a cleaning brush plate 43. The support plate 41 is fixed to the outer wall on both sides of the air inlet 2 and a servo motor is installed at its rear end. The elastic telescopic shaft 42 is connected to the front side of the support plate 41, the cleaning brush plate 43 is connected to the outer end of the elastic telescopic shaft 42, and the inner side of the cleaning brush plate 43 is provided with steel wire bristles, and the dust collecting box 1 is provided with a multi-directional spray mechanism 6 above the air inlet 2, and the multi-directional spray mechanism 6 includes a water tank 61, fixed strip plate 62, pressure pump 63, solid spray pipe 64 and dynamic spray pipe 65. When the dust collecting box 1 of this structure is used in a mine, the air containing dust is introduced from the air inlet 2 through the fan, and the filter 3 will block and filter most of the dust particles, and the servo motor on the support plate 41 of the pretreatment mechanism 4 drives the elastic telescopic shaft 42 to rotate. When the elastic telescopic shaft 42 rotates, it drives the cleaning brush plate 43 to swing synchronously so that the wire bristles are in friction contact with the outer surface of the filter 3, effectively removing the larger particles attached to the filter 3, and preventing these large particles from entering the subsequent dust removal structure inside the dust collecting box 1 and causing blockage. At the same time, the multi-directional spray mechanism 6 works synchronously, and the water in the water tank 61 is transported to the solid spray pipe 64 and The dynamic spray tube 65 forms a dense water mist, which is fully mixed with the dust-laden air, so that the fine dust particles combine with the water droplets to become heavier and settle, thereby achieving an efficient dust removal effect. The design of the dynamic spray tube 65 allows its angle to be adjusted, ensuring that even under conditions of narrow space and complex structure inside the mine, it can effectively handle airflows in different directions, greatly improving the coverage and efficiency of dust removal. This not only solves the problem of poor dust removal effect of traditional ventilation and dust removal devices in high dust concentration environments, but also effectively avoids the situation of frequent cleaning and maintenance due to equipment blockage, reducing operating costs and workload. The water tank 61 is installed on one side of the outside of the dust collecting box 1 through a bracket. The water tank 61 serves as a water storage unit, which is convenient for replenishing and replacing water sources, and is solid. The plate 62 is fixed to the top of the front end of the dust collecting box 1, and the pressure pump 63 and the solid spray pipe 64 are respectively installed on the upper and lower ends of the fixed strip plate 62 through fixing parts. The suction end of the pressure pump 63 is connected to the inside of the water tank 61 through a connecting pipe, and the liquid discharge end of the pressure pump 63 is also connected to the solid spray pipe 64 through a connecting pipe. The dynamic spray pipe 65 is symmetrically inclined and arranged at the bottom of the solid spray pipe 64, and a guide hose 66 is connected between the dynamic spray pipe 65 and the solid spray pipe 64. A vertical rod 67 is provided in the middle of the bottom of the solid spray pipe 64, and the outer movable sleeve of the vertical rod 67 is provided with a movable sleeve 68. The inner ends of the dynamic spray pipes 65 are hinged to the outer wall of the movable sleeve 68 through a rotating pin, and the outer ends of the dynamic spray pipes 65 are also hinged to the outer wall of the dust collecting box 1 through a rotating pin.In addition, a cylinder 69 is fixed to the middle of the bottom of the fixed strip plate 62 by bolts, and the output end of the cylinder 69 is fixedly connected to the outer wall of one side of the movable sleeve 68 through a connecting piece. The solid spray pipe 64 and the dynamic spray pipe 65 of this structure together constitute the main part of the spray system. They are connected to the movable sleeve 68 by a rotating pin hinge, ensuring that the dynamic spray pipe 65 can freely adjust the angle within a certain range. Specifically, when the cylinder 69 is actuated, its output end pushes the movable sleeve 68 to move through the connecting piece, thereby driving the dynamic spray pipe 65 to change the spray angle, ensuring that the water mist can cover a wider area according to actual needs. The flexible adjustment of water mist spraying is realized in the region or specific direction, which greatly improves the working efficiency and application range of the mine ventilation and dust removal device, reduces the need for manual intervention, and further optimizes the effect of mine environmental management. The elastic telescopic shaft 42 includes an outer shaft 4201, an inner shaft 4202 and a tension spring 4203. The inner end of the outer shaft 4201 is connected to the output shaft of the servo motor on the support plate 41, and the inner shaft 4202 is movably extended into the interior of the outer shaft 4201. The tension spring 4203 is sleeved on the outside of the outer end of the inner shaft 4202. The cleaning brush plate 43 of this structure is swinging During the dynamic movement, the inner shaft 4202 of the elastic telescopic shaft 42 will slide to a certain extent inside the outer shaft 4201. At the same time, the elastic force of the tension spring 4203 enables the inner shaft 4202 to produce a certain expansion and contraction in the axial direction. In this way, the cleaning brush plate 43 produces a certain elastic expansion and contraction force during cleaning, which better fits the outer surface of the filter screen 3 and effectively removes larger particles attached thereto, thereby improving the cleaning effect and reliability of the device. A plurality of guide holes 21 are evenly arranged at the lower end of the air inlet 2, and the aperture of the guide hole 21 is 3.0-5.0 cm. The dust collecting box 1 is located below the air inlet 2. A collection frame 5 is provided on the side, and a waste liquid filter plate 51 is embedded inside the collection frame 5. The diversion holes 21 of this structure can evenly guide the water and dust mixture sprayed from the dynamic spray pipe 65 to flow smoothly into the collection frame 5 below. The waste liquid filter plate 51 can effectively intercept and filter out larger particles and impurities in the wastewater, ensuring the initial purification of the wastewater. In this way, the wastewater sprayed on the filter 3 by the dynamic spray pipe 65 can be effectively collected and preliminarily treated by the collection frame 5 after flowing out of the diversion holes 21. This not only prevents the wastewater from directly flowing into the mine and causing secondary pollution, but also improves the cleaning effect and environmental performance of the entire device.
[0019] Working principle: When using the mine ventilation and dust removal device, the fan on the dust collecting box 1 is started first, and the dust-containing air is sucked in from the air inlet 2. When the air passes through the filter 3 inside the air inlet 2, most of the dust particles are blocked by the filter 3. At the same time, the pretreatment mechanism 4 starts to work, and the servo motor installed at the rear end of the support plate 41 drives the elastic telescopic shaft 42 to rotate. The inner shaft 4202 of the elastic telescopic shaft 42 slides inside the outer shaft 4201. The elastic force of the tension spring 4203 enables the inner shaft 4202 to be able to stretch and retract along the axial direction, driving the cleaning brush plate 43 to swing. The steel wire bristles on the cleaning brush plate 43 contact the outer surface of the filter 3 and remove the larger particles attached. While the pretreatment mechanism 4 is working, the multi-directional spray mechanism 6 is started, and the water in the water tank 61 is pressurized by the pressure pump 63 and transported to the solid The solid spray tube 64 is then distributed to the dynamic spray tube 65 by the solid spray tube 64 to form a fine water mist that is sprayed toward the dust-laden air. The fine dust particles combine with the water droplets to become heavy and settle. The angle of the dynamic spray tube 65 can be adjusted by the action of the cylinder 69, that is, the cylinder 69 pushes the movable sleeve 68 to move vertically, and the movable sleeve 68 drives the dynamic spray tube 65 to change the spray direction, ensuring that the water mist can cover a wider area or a specific direction. During the spraying process, part of the water and dust mixture will flow into the collecting frame 5 below the dust collecting box 1 through the guide holes 21 evenly arranged at the lower end of the air inlet 2. The waste liquid filter plate 51 inside the collecting frame 5 performs preliminary filtration on the sewage and intercepts larger particles and impurities. Finally, the air after filtration and spraying continues to enter the dust collecting box 1 for further purification, thereby completing a series of tasks.
