[0022] During use, after the assembled guard plate 3 is installed in the notch 2, the limit frame 11 is introduced into the mine ventilation pipe 1. At this time, the two groups of activated carbon plates 13 form an air purification structure inside the mine ventilation pipe 1, that is, after the external air is led into the mine ventilation pipe 1, the air passes through the activated carbon plate 13 and is purified, and the purified air flows into the mine and prevents dust in the air from entering the mine; a rubber sheet can be bonded to the inner wall of the mine ventilation pipe 1, and when the limit frame 11 is pushed into the mine ventilation pipe 1, the rubber sheet is clamped between the limit frame 11 and the inner wall of the mine ventilation pipe 1, reducing the gap between the limit frame 11 and the inner wall of the mine ventilation pipe 1; the reason for setting the metal fine mesh plate 14 is to prevent the particles carried in the introduced air from hitting the activated carbon plate 13, that is, to protect the activated carbon plate 13, thereby making full use of The activated carbon plate 13 purifies the air. In order to prevent the holes of the metal fine mesh plate 14 from being blocked, the surface of the metal fine mesh plate 14 is cleaned regularly. The specific operation is as follows: after the switch of the servo motor 21 is triggered, the servo motor 21 drives the brush plate 22 to rotate, and the bristles on the surface of the brush plate 22 adhere to the metal fine mesh plate 14. In the process that the brush plate 22 follows the rotation of the servo motor 21, the surface of the metal fine mesh plate 14 is cleaned; when the activated carbon plate 13 needs to be replaced, first remove the assembly guard plate 3 from the notch 2, then loosen the screw 19, and remove the traction plate 18 from the assembly guard plate 3, so that the front of the metal fine mesh plate 14 is unobstructed, remove the nut 17 from the screw 16, pull the metal fine mesh plate 14 out of the screw 16, and then take out the activated carbon plate 13 from the mounting frame 12 for replacement.

The surface of the head 28 and the injection hole 27 are provided with internal threads, and the surface of the head 28 is provided with external threads, and the external threads and the internal threads are matched and connected. A cross screw handle is fixed to the bottom surface of the head 28, and a micro water pump 30 is fixed to the inner wall of the liquid collecting tank 23. The suction pipe of the micro water pump 30 extends to the bottom end of the liquid collecting tank 23, and the discharge pipe of the micro water pump 30 is plugged into the bottom end of the atomizing nozzle 29; the liquid collecting tank 23 is an arc-shaped groove, and a plurality of air dispersion holes 24 are provided. The plurality of air dispersion holes 24 are arranged and distributed at equal distances and sizes along the curved surface of the liquid collecting tank 23, and a metal fine mesh plate 25 is fixed to the inner annular surface of the assembled guard plate 3, and the metal fine mesh plate 25 covers the liquid collecting tank 23.

[0024] When in use, disinfectant and air deodorizing and purifying liquid are respectively injected into the two liquid collecting tanks 23 in advance. During operation, the assembled guard plate 3 is removed from the bottom of the mine ventilation pipe 1 to the ground, and the notch of the injection hole 27 is facing upward. Then, the disinfectant and air deodorizing and purifying liquid are respectively injected into the two liquid collecting tanks 23, and the sealing head 28 is screwed and sealed in the corresponding injection hole 27, that is, each time the activated carbon plate 13 is inspected or replaced, the liquid inside the liquid collecting tank 23 is supplemented; when the assembled guard plate 3 is installed in the mine, After reaching the bottom of the ventilation pipe 1, when the introduced air is disinfected regularly, the switch of the micro water pump 30 inside the liquid collection tank 23 filled with disinfectant is triggered, and the micro water pump 30 sucks the disinfectant and injects it into the atomizing nozzle 29, and then sprays it out through the atomizing nozzle 29, and the disinfected air is dispersed downward into the mine through the air dispersion holes 24; when it is necessary to deodorize and purify the air introduced into the mine regularly, another micro water pump 30 is triggered to suck the air deodorization and purification liquid and inject it into the corresponding atomizing nozzle 29 and then spray it out through atomization.

[0025] The two parallel side walls of the outer ring groove 35 are both plugged with baffles 32, and the two parallel side walls of the outer ring groove 35 are both provided with embedded grooves 31, which are arc-shaped grooves. The baffles 32 correspond to the embedded grooves 31 one by one, and the baffles 32 are plugged into the embedded grooves 31. The width of the baffles 32 is greater than the depth of the embedded grooves 31. A rubber gasket 33 is fixed to the inner ring surface of the baffle 32, and the rubber gasket 33 is clamped between the outer ring groove 35 and the baffle 32 to produce elastic deformation; the outer ring surface of the baffle 32 is screwed with a clamping screw 34, and the clamping screw 34 passes through the baffle 32 and the rubber gasket 33 and then rests on the surface of the outer ring groove 35. The reason why the outer ring groove 35 is provided on the outer ring surface of the assembled guard plate 3 is to slide and connect the baffle plate 32 on the two parallel side walls of the outer ring groove 35. When it is necessary to introduce air into the interior of the mine, the baffle plate 32 is inserted into the embedded groove 31, and the baffle plate 32 no longer blocks the air holes 24, so that the introduced air can flow into the mine from the air holes 24. When it is necessary to close the air holes 24, the two baffle plates 32 are pulled together, and the clamping screw 34 is screwed against the inner ring surface of the outer ring groove 35 to brake the baffle plate 32. At this time, the air holes 24 are closed, and the mine ventilation pipe 1 is blocked from introducing air into the mine.

[0026] The detailed usage process is as follows: 1. Installation and fixation of assembled guard plate Installation process: The assembly guard plate 3 is designed as a circular plate with slots 4 at both ends. Align the bottom of the assembly guard plate 3 with the notch 2 on the mine ventilation pipe 1 and push it upward. During the pushing process, the bottom surface of the assembly guard plate 3 will produce elastic deformation along the inclined surface of the elastic hanging plate 9, causing the elastic hanging plate 9 to open outward. When the assembly guard plate 3 is completely pushed into the notch 2, the elastic hanging plate 9 rebounds and its bottom end extends into the slot 4, realizing the temporary suspension limit of the assembly guard plate 3.

[0027] Fixing process: The nut 7 is set on the screw rod 6 and screwed to ensure that the assembled guard plate 3 is firmly fixed under the mine ventilation pipe 1. The card slot 4 is not only used for suspension limit, but also provides an operating space for screwing the nut 7.

[0028] 2. Air Purification and Particle Removal Air purification: The inner ring surface of the assembled guard plate 3 is fixed with a limit frame 11, on which an activated carbon plate 13 and a metal fine mesh plate 14 are installed. When the external air passes through the mine ventilation pipe 1, it first passes through the metal fine mesh plate 14 to filter out large particles, and then passes through the activated carbon plate 13 for purification, thereby preventing dust from entering the mine and purifying the air.

[0029] Particle cleaning: The front of the metal fine mesh plate 14 is connected to a brush plate 22, which is driven by a servo motor 21. When the particles on the metal fine mesh plate 14 need to be cleaned, the switch of the servo motor 21 is triggered to rotate the brush plate 22, and the surface of the metal fine mesh plate 14 is cleaned by the bristles.

[0030] 3. Liquid disinfection and deodorization Liquid injection: The inner annular surface of the assembled guard plate 3 is provided with two liquid collecting grooves 23, which are used to contain disinfectant and air deodorizing and purifying liquid respectively. The corresponding liquid is injected into the liquid collecting grooves 23 through the liquid injection hole 27, and then the liquid injection hole 27 is screwed and blocked with a sealing head 28.

[0031] Disinfection and deodorization: A micro pump 30 is provided on the bottom of the liquid collecting tank 23 to pump the liquid in the liquid collecting tank 23. When disinfection is required, the micro pump 30 in the liquid collecting tank 23 containing disinfectant is triggered, and the disinfectant is injected into the atomizing nozzle 29 and then sprayed out in atomization. When deodorization and purification are required, the micro pump 30 in another liquid collecting tank 23 is triggered, and the air deodorization and purification liquid is injected into the corresponding atomizing nozzle 29 and then sprayed out in atomization.

[0032] 4. Opening and closing of air vents Opening state: The outer ring surface of the assembled guard plate 3 is provided with an outer ring groove 35, and baffles 32 are inserted on two parallel side walls of the outer ring groove 35. When it is necessary to introduce air into the mine, the baffle 32 is inserted into the embedded groove 31, and the baffle 32 no longer blocks the air dispersion hole 24, and air can flow into the mine through the air dispersion hole 24.

[0033] Closed state: When the air holes 24 need to be closed, the two baffles 32 are pulled together, and the clamping screw 34 is screwed against the inner ring surface of the outer ring groove 35 to brake the baffle 32, thereby closing the air holes 24 and blocking the mine ventilation pipe 1 from introducing air into the mine.

[0034] In summary, the safe and environmentally friendly dust removal device for mine construction realizes the purification, disinfection and deodorization of the air in the mine ventilation pipe through multiple links such as the installation and fixation of assembled guard plates, air purification and particle cleaning, liquid disinfection and deodorization purification, and the opening and closing of air holes.
