[0029] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Combination Figures 1-7 As shown, an ultra-deep vertical shaft ventilation and cooling system includes a vertical shaft body 1, a platform surface at the top of the shaft serving as an installation surface 2, and a base 3 on one side of the installation surface 2. A support box 4 is installed on the side of the base 3 away from the vertical shaft, a dust collection box 5 is installed on the upper side of the support box 4, and a top box 6 is installed on the upper side of the dust collection box 5. An air inlet 7 is provided on the side of the dust collection box 5 away from the vertical shaft, and an air intake fan 8 is installed inside the air inlet 7.
[0031] The support box 4 has first rollers 9 on both sides inside. A transmission box 10, connected to the two first rollers 9, is located at the front of the support box 4, and a drive motor 11 is mounted on the transmission box 10. The top box 6 has second rollers 12 on both sides inside. The second rollers 12 are connected to the top box 6 via spiral springs 13. The first rollers 9 and second rollers 12 are connected by a flexible filter plate 14. The dust collection box 5 contains a cleaning assembly corresponding to the flexible filter plate 14, and a dust discharge port is located at the front of the dust collection box 5.
[0032] A refrigeration box 15, connected to the dust collection box 5, is installed on the side of the base 3 near the vertical shaft. A refrigeration device 16 is installed on the front of the refrigeration box 15, and an auxiliary refrigeration component is installed on the upper side of the refrigeration box 15. The refrigeration box 15 has a cooling chamber 17 and a transfer chamber 18 inside. The cooling chamber 17 has multiple refrigerant channels 19 arranged at equal intervals. An air collecting hood 20 is installed on the side of the refrigeration box 15 near the vertical shaft. The air passages between adjacent refrigerant channels 19 serve as air passages, and the two ends of the air passages are connected to the air collecting hood 20 and the transfer chamber 18, respectively.
[0033] A conveying fan 21 is installed on one side of the air collecting hood 20. The exhaust end of the conveying fan 21 is connected to a top pipe 22. The bottom end of the top pipe 22 is connected to a first extension pipe 23. The bottom end of the first extension pipe 23 is connected to a bottom pipe 40.
[0034] An exhaust fan 24 is provided on the other side of the mounting surface 2. An exhaust pipe 25 is connected to the exhaust end of the exhaust fan 24, and a second extension pipe 26 is connected to the bottom end of the exhaust pipe 25.
[0035] The cleaning assembly includes a V-shaped collection trough 27 inclined inside the dust collector 5. The V-shaped collection trough 27 is inclined at one high and one low position to facilitate dust discharge. One side of the V-shaped collection trough 27 is in close contact with the flexible filter plate 14. An inclined limiting plate 28 corresponding to the V-shaped collection trough 27 is provided inside the dust collector 5. The flexible filter plate 14 is located between the V-shaped collection trough 27 and the inclined limiting plate 28. A support column 29 is installed below the V-shaped collection trough 27.
[0036] The auxiliary cooling component includes an auxiliary air duct 30, inside which multiple sets of heat dissipation fins 31 are vertically arranged, with the lower side of the heat dissipation fins 31 extending into the interior of the cooling box 15. One side of the auxiliary air duct 30 is connected to the upper side of the transfer cavity 18 via a delivery pipe 32, and an inclined guide frame 33 is installed at the connection point. The inclined guide frame 33 has air passage holes, and the transfer cavity 18 is connected to one side of the dust collection box 5.
[0037] When the device is running, the air intake fan 8 is started first. External air is drawn into the dust collection box 5 through the air intake 7. The U-shaped rain shield 35 on the upper side of the air intake 7 prevents rainwater from entering. The air first passes through the flexible filter plate 14 for preliminary filtration to remove large particles of dust and impurities.
[0038] The flexible filter plate 14 is driven by the drive motor 11 through the transmission box 10 and the first roller 9 and the second roller 12 to move in a cycle. When the drive motor 11 is running, the first roller 9 can be used to wind up the flexible filter plate 14. During the winding process, the V-shaped collection groove 27 in the cleaning component, with the cooperation of the inclined limiting plate 28, is in close contact with the flexible filter plate 14, thereby scraping off the dust attached to the flexible filter plate 14 and collecting it inside the V-shaped collection groove 27. The vibration motor 39 can be started at regular intervals to help the impurities in the V-shaped collection groove 27 slide better into the collection box 34. Guide grooves are provided on both sides of the dust discharge port. An electric push rod is installed on the upper side of the dust discharge port. The output end of the electric push rod is connected to a sliding plate 38 that is slidably connected to the guide groove, which can open or close the dust discharge port. When the dust collector 5 is receiving air, the dust discharge port is closed; the guide groove guides the sliding plate 38 up and down.
[0039] After initial filtration, the air enters the refrigeration box 15, the refrigeration equipment 16 is started, and the refrigerant in the refrigerant channel 19 circulates, absorbing heat from the air and achieving initial cooling of the air. Meanwhile, the baffles 36 arranged vertically in the air passage between adjacent refrigerant channels 19 increase the contact area between the air and the outer wall of the refrigerant channel 19, thereby improving the refrigeration efficiency.
[0040] Meanwhile, within the auxiliary air duct 30 of the auxiliary cooling component, one side of the auxiliary air duct 30 is connected to the upper side of the transfer chamber 18 via a delivery pipe 32, and an inclined guide frame 33 is installed at the connection point. The transfer chamber 18 is connected to one side of the dust collection box 5, thereby allowing the inclined guide frame 33 to introduce some air into the auxiliary air duct 30 to blow air onto multiple sets of heat dissipation fins 31. The multiple sets of heat dissipation fins 31 further absorb the heat in the cooling box 15, and the cold air is delivered to the transfer chamber 18 via the delivery pipe 32. Finally, it mixes with the initially cooled air to improve the overall cooling effect. This allows the entire system to meet the continuous and efficient cooling requirements in ultra-deep vertical shafts while significantly reducing energy consumption, saving a lot of operating costs for the construction project and improving economic efficiency.
[0041] Subsequently, the conveying fan 21 is started, which transports the cooled air to the bottom of the shaft through the jacking pipe 22, the first extension pipe 23, and the bottom pipe, providing fresh and cool air for the underground workers. At the same time, the exhaust fan 24 extracts the polluted air in the shaft through the exhaust pipe 25 and the second extension pipe 26, forming an air circulation and maintaining the air quality in the shaft.
[0042] The main body 1 of the shaft is equipped with multiple sets of semi-circular fixing frames 37. Each semi-circular fixing frame 37 has a limiting ring in the middle. The jacking pipe 22, the first extension pipe 23, the bottom pipe 40, the extraction pipe 25, and the second extension pipe 26 are respectively inserted into the corresponding limiting rings for fixation. The semi-circular fixing frames 37 are connected to the main body 1 of the shaft via anchor bolts, providing support and positioning for the aforementioned pipes, preventing significant shaking and displacement of the pipes within the shaft, and ensuring the basic stability of the ventilation path.
