[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. A high-efficiency dust removal component is provided. Cold water is transported to the condensate tank through a refrigeration circulation pump. The cold water wraps the spiral tube. Under the action of heat conduction, the spiral tube is always in a low-temperature state. With the guidance of the axial flow fan, the airflow carries the floating dust and water mist into the spiral tube through the wind tube. Under the guidance of the spiral tube, the airflow forms a vortex after entering the spiral tube. Under the action of centrifugal force, most of the water mist that absorbs dust is adsorbed on the inner wall of the spiral tube. Under the action of temperature difference, the water mist is cooled and meets the defogger, so that the water mist quickly condenses into water droplets. Under the action of gravity, the water droplets mixed with dust are discharged through the sewage pipe, realizing preliminary filtration. When the filter element filters dust in the subsequent process, the filtration pressure of the filter element is reduced, so that the equipment can work continuously for a longer time and improve the filtration efficiency. After the dust that has not been absorbed by the water mist enters the spiral tube, the water mist will contact with the dust again under the disturbance of the vortex to absorb the dust, further reducing the filtration pressure of the filter element and further extending the continuous working time of the equipment.

[0023] The remaining dust and a small amount of water mist are filtered through three filter elements, and the clean air is discharged from the axial flow fan to filter the tunnel air. The moving motor drives the moving block to move back and forth inside the limit slot, thereby driving the filter box, axial flow fan and condensate tank to move with it, thereby expanding the range of action of the wind tube. The increase in the dust suction range of the device increases the dust removal speed and reduces the harm of dust to on-site workers. In addition, when excavating the tunnel, the engineering vehicle can pass through the bottom of the arc frame without hindering the passage of the engineering vehicle, making the tunnel construction more convenient and indirectly increasing the tunnel construction speed;

[0024] During the filtering and dust removal process, the vibration motor drives the vibration plate to vibrate. Under the elastic support of the vibration spring, the vibration motor drives the filter element to vibrate. The vibration of the filter element cooperates with the effect of gravity, and most of the dust will not stick to the surface of the filter element, so that the air can pass through the three filter elements quickly, and the filtering effect is better.

[0025] 2. A refrigeration auxiliary component is provided. The air pump delivers high-pressure air to the inside of the arc box. The high-pressure air is ejected from the air diffusion holes. The ejected high-pressure gas spreads to the surroundings to form an air curtain. The air curtain can prevent dust from spreading to other locations in the tunnel, protecting the on-site working environment and ensuring the health of workers in other locations in the tunnel;

[0026] When the temperature of the tunnel is high, the cooling fan guides the airflow to pass through the surface of the condensate tank. The low-temperature condensate tank cools the airflow, which is diffused to the surroundings under the guidance of the cooling fan, thereby reducing the temperature of the on-site working environment. The driving motor drives the rotating ring and the cooling fan to swing back and forth, thereby increasing the range of the cooling fan and further improving the cooling speed. At the same time, ice cubes are placed inside the ice rack. When the air pump is working, the air flows through the ice storage bin to cool down, so that the air ejected from the air diffusion hole is cold air. The cooling fan further improves the cooling effect. The working environment can also be cooled during the dust removal process of the device, thereby preventing dust from spreading and providing a comfortable working temperature, further improving working comfort.

[0027] By adjusting the electric push rod, the adjusting rack is driven to move back and forth, driving the adjusting gear to rotate, and then driving the adjusting shaft to rotate, so that the air duct swings up and down, expanding the range of action of the air duct and improving the dust removal efficiency. The adjusting electric push rod also drives the cooling fan to swing, further improving the cooling speed.

[0028] After the work is completed, the cleaning nozzle can be controlled to spray high-pressure air or high-pressure water through the control of the switch valve, swing electric push rod, air pump and water tank to clean the filter element. There is no need to manually disassemble the filter element for cleaning, which is convenient and quick, and further reduces the labor intensity.

[0029] In summary, the moving motor of the high-efficiency dust removal component drives the moving block to move, thereby expanding the range of action of the air condenser. The adjusting electric push rod in the refrigeration auxiliary component drives the air condenser to swing up and down, thereby expanding the range of action of the air condenser. The two components cooperate with each other to further improve the dust removal efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Each electrical component can be controlled by the external controller, which is convenient for automatic control of the overall equipment.

[0058] The working principle and use process of the present invention are as follows: a moving wheel is arranged at the bottom of the moving seat 1. During construction, the moving seat 1 is used to move the whole device to the construction site, and the moving seats 1 at both ends are moved to the two sides of the tunnel respectively. During construction, the refrigeration circulation pump 225 is started, and the cold delivery end of the refrigeration circulation pump 225 delivers cold water to the cold delivery main pipe 224. The cold water flows through the cold delivery main pipe 224 and the cold delivery branch pipe 226 in turn and enters the condensation tank 211. The cold water wraps the spiral tube 220 and finally flows through the return branch pipe 227 and the return main pipe 228 through the refrigeration circulation pump 225. The return end of the ring pump 225 enters the interior of the refrigeration circulation pump 225, and the refrigeration circulation pump 225 continuously cools the water, so that the water in the condensation tank 211 is always in a low temperature state. Under the effect of heat conduction, the spiral tube 220 is always in a low temperature state. At the same time, the storage box 235 stores a defogger inside, and the quantitative valve 234 is controlled to quantitatively transport the defogger into the interior of the spiral tube 220. The defogger adheres to the inner wall of the spiral tube 220 to form an anti-fog layer. When the water mist hits the inner wall of the spiral tube 220, the defogger can quickly condense the water mist into water droplets.

[0059] The external sprayer is moved to the construction site, and the external sprayer is started to spray water mist, and the sprayed water mist absorbs the dust on the site. At the same time, the external axial flow fan 210 is started. Under the guidance of the axial flow fan 210, the airflow carries the floating dust and water mist through the wind tube 222 into the spiral tube 220. Under the guidance of the spiral tube 220, the airflow forms a vortex after entering the spiral tube 220. Under the action of centrifugal force, most of the water mist that absorbs the dust hits the inner wall of the spiral tube 220, so that the water mist is adsorbed on the inner wall of the spiral tube 220. The temperature of the water mist in the tunnel is higher than the temperature of the inner wall of the high-pressure spiral tube 220. The water mist is cooled and meets the defogger, so that the water mist quickly condenses into water droplets. Under the action of gravity, the water droplets mixed with dust slide down the inner bottom of the spiral tube 220. The water mist flows through the drain pipe 236, the drainage branch pipe 237 and the drainage main pipe 238 and enters the dirt storage box 239. Most of the water mist flows through the spiral tube 220 and condenses into water droplets and is discharged, thus achieving preliminary filtration. When the filter element 214 filters dust subsequently, only a small amount of water mist is adsorbed on the filter element 214, which reduces the filtration pressure of the filter element 214 and enables the filter element 214 to continue to work, greatly extending the replacement and cleaning cycle of the filter element 214, allowing the equipment to continue to work for a longer time and improving the filtration efficiency. After the dust that has not been adsorbed by the water mist enters the spiral tube 220, the water mist will contact the dust again under the vortex disturbance to adsorb the dust, further reducing the filtration pressure of the filter element 214 and further extending the continuous working time of the equipment.

[0060] The remaining dust and a small amount of water mist are filtered by three filter elements 214, and the clean air is discharged from the axial flow fan 210 to filter the tunnel air. At the same time, the mobile motor 207 also drives the mobile gear 208 to rotate back and forth. The mobile gear 208 meshes with the arc-shaped rack 206, thereby driving the mobile block 204 to move back and forth inside the limit groove 203. Under the connection and driving action of the hanging frame 205 and the adjustment frame 315, the filter box 209, the axial flow fan 210 and the condensation tank 211 are driven to follow the movement, thereby expanding the range of action of the wind tube 222. The increase in the dust collection range increases the dust removal speed and reduces the harm of dust to workers on site. At the same time, the adjustment push rod 318 is started, and the adjustment push rod 318 drives the adjustment rack 319 to move back and forth, drives the adjustment gear 317 to rotate, and then drives the adjustment shaft 316 to rotate, so that the wind tube 222 swings up and down, further expanding the action range of the wind tube 222 and further improving the dust removal efficiency. In addition, when excavating the tunnel, the engineering vehicle can pass through the bottom of the arc frame 202 without hindering the passage of the engineering vehicle, making the tunnel construction more convenient and indirectly improving the tunnel construction speed.

[0061] When there is a lot of dust accumulated at the bottom of the inner side of the spiral tube 220, clean water is transported to the inner side of the water main pipe 230 through the water delivery pump water storage tank 229. The clean water flows through the water delivery branch pipe 231, the water distribution box 232 and the three-way pipe 233 into the inner side of the spiral tube 220 to flush the inner wall of the spiral tube 220. The water entering the inner side of the spiral tube 220 washes away the dust at the inner side of the bottom of the spiral tube 220, and finally flows through the sewage pipe 236, the drainage branch pipe 237 and the drainage main pipe 238 into the sewage storage tank 239 to collect the sewage. The device has a self-cleaning function, and there is no need to manually clean the device, which reduces the labor intensity.

[0062] During the working process of filtering and dust removal, the vibration motor 219 also runs at the same time, and the vibration motor 219 drives the vibration plate 218 to vibrate, and the vibration plate 218 contacts the filter element 214. Under the elastic support of the vibration spring 215, the vibration motor 219 drives the filter element 214 to vibrate. The vibration of the filter element 214 cooperates with the gravity, and the dust on the surface of the filter element 214 will fall into the bottom of the inner side of the filter box 209 through the dust outlet 217. During the working process of filtering and dust removal of the device, most of the dust will not adhere to the surface of the filter element 214, so that the air can quickly pass through the three filter elements 214, so that the filtering effect is better;

[0063] At the same time, during the filtering and dust removal, the air pump 301 delivers high-pressure air to the inside of the arc box 302, and the high-pressure air is ejected from the air diffusion holes 303. The ejected high-pressure gas spreads around to form an air curtain, which can prevent dust from spreading to other locations in the tunnel, thereby protecting the on-site working environment and ensuring the health of workers in other locations in the tunnel;

[0064] During tunnel construction, the operation of mechanical equipment will generate a lot of heat, causing the temperature inside the tunnel to rise and the on-site working environment to be uncomfortable. When the temperature of the tunnel is high, the cold end of the refrigeration circulation pump 225 transports cold water to the inside of the condensate tank 211. The surface of the condensate tank 211 is provided with a heat sink. The drive motor 322 and the cold fan 324 are started. The cold fan 324 guides the airflow to pass through the surface of the condensate tank 211. The low-temperature condensate tank 211 cools the airflow, and under the guidance of the cold fan 324, it diffuses to the surroundings, thereby reducing the temperature of the on-site working environment and improving working comfort. The rotating gear 321 and the driving gear 323 are meshed, and the driving motor 322 drives the rotating ring 320 and the cold water fan to swing back and forth, thereby increasing the range of action of the cold fan 324 and making the cooling The speed is faster. At the same time, ice cubes are placed inside the ice rack 326. The air outlet end of the air pump 301 delivers high-pressure air to the inside of the arc box 302. The air inlet end of the air pump 301 is connected to one side of the ice storage bin 325. The air inside the air pump 301 flows through the ice storage bin 325 to cool down, so that the air ejected from the air diffusion hole 303 is cold air. The cooling effect is further improved in conjunction with the cooling fan 324. The working environment can also be cooled during the dust removal process of the device to prevent dust from spreading while providing a comfortable working temperature, further improving the working comfort. At the same time, the water produced by the melted ice is stored at the bottom of the inner side of the ice storage bin 325. The return water pump 328 can transport the melted water to the inside of the water storage tank 229 to recycle the ice water.

[0065] After the work is completed, if there is a lot of dust remaining on the surface of the filter element 214 and it does not need to be washed with water, the switch valve 305 is controlled, the switch valve 305 connected to the gas branch pipe 306 is opened, and the switch valve 305 connected to the cleaning branch pipe 307 is closed, and the high-pressure gas inside the arc box 302 can flow through the gas branch pipe 306 and the rotary joint 308 into the cleaning nozzle 309, and finally spray out from the cleaning nozzle hole 310. The sprayed high-pressure gas can wash away the dust adhering to the surface of the filter element 214. When the filter element 214 needs to be cleaned, the switch valve 305 connected to the gas branch pipe 306 is opened, and the switch valve 305 connected to the cleaning branch pipe 307 is closed. 06 is closed, and the switch valve 305 connected to the cleaning branch pipe 307 is opened, so that the water inside the water main pipe 230 can flow through the cleaning branch pipe 307 and the rotary joint 308 into the cleaning nozzle 309, and finally spray out from the cleaning nozzle hole 310 to clean the filter element 214. The swinging electric push rod 312 can drive the cleaning nozzle 309 to swing, so that the clean water or high-pressure air sprayed from the cleaning nozzle hole 310 has a wider range of action, and there is no need to manually disassemble and assemble the filter element 214 for cleaning, which is convenient and quick, and further reduces the labor intensity;

[0066] The cold supply branch pipe 226, the return branch pipe 227, the water supply branch pipe 231, the drainage branch pipe 237, the cleaning branch pipe 307 and the dust exhaust pipe 314 are all corrugated telescopic hoses. When the filter box 209, the axial flow fan 210 and the condensate tank 211 move, the cold supply branch pipe 226, the return branch pipe 227, the water supply branch pipe 231, the drainage branch pipe 237, the cleaning branch pipe 307 and the dust exhaust pipe 314 will not hinder the movement of the filter box 209, the axial flow fan 210 and the condensate tank 211.
