[0023] The remaining dust and a small part of water mist are filtered through three filter cores, and clean air is discharged from the axial flow fan, realizing the filtration of tunnel air. The moving motor drives the moving block to move back and forth in the limiting groove, thereby driving the filter box, axial flow fan and condensate tank to move, thereby expanding the range of the wind cylinder. The increase of the dust collection range of the device improves the dust removal speed and reduces the harm of dust to the workers on site. Moreover, during tunnel excavation, the engineering vehicle can pass through the bottom of the arc-shaped frame without hindering the passage of the engineering vehicle, making the tunnel construction more convenient and indirectly improving the tunnel construction speed.
[0024] During the filtration and dust removal process, the vibration motor drives the vibration plate to vibrate, and under the elastic support of the vibration spring, the vibration motor drives the filter core to vibrate. The vibration of the filter core combined with the action of gravity prevents most of the dust from adhering to the surface of the filter core, allowing air to quickly pass through the three filter cores for better filtration effect.

[0026] When the temperature of the tunnel is high, the cold fan guides the airflow to pass through the surface of the condensate tank, the low-temperature condensate tank cools the airflow, and the airflow is diffused in all directions under the guidance of the cold fan, thereby reducing the temperature of the working environment, and the rotating ring and the cold fan are driven by the driving motor to swing back and forth, thereby increasing the action range of the cold fan and further improving the cooling speed.
[0027] By adjusting the electric push rod to drive the adjusting rack to move back and forth, the adjusting gear is driven to rotate, the adjusting shaft is driven to rotate, the wind collecting barrel is swung up and down, the action range of the wind collecting barrel is expanded, the dust removal efficiency is improved, and the cold fan is also swung by the adjusting electric push rod, and the cooling speed is further improved.

[0029] In summary, the high-efficiency dust removal assembly moves the moving block by the moving motor, the action range of the wind collecting barrel is expanded, the wind collecting barrel swings up and down by the adjusting electric push rod in the refrigeration auxiliary assembly, the action range of the wind collecting barrel is expanded, and the dust removal efficiency is further improved by the cooperation of the two assemblies.

[0058] The working principle and use process of the application are as follows: the mobile base 1 is provided with mobile wheels, the whole device is moved to the construction site by the mobile base 1 during construction, and the two ends of the mobile base 1 are moved to the two sides of the tunnel, during construction, the refrigeration circulating pump 225 is started, the refrigeration circulating pump 225 sends cold water to the inside of the cold water supply main pipe 224 through the cold water supply end, the cold water flows through the cold water supply main pipe 224, the cold water supply branch pipe 226 and enters the inside of the condensate tank 211 in turn, the cold water wraps the spiral pipe 220, and finally flows through the backflow branch pipe 227 and the backflow main pipe 228 and enters the inside of the refrigeration circulating pump 225 through the backflow end of the refrigeration circulating pump 225, the refrigeration circulating pump 225 continuously refrigerates the water, so that the water in the condensate tank 211 is always in a low-temperature state, under the action of heat conduction, the spiral pipe 220 is always in a low-temperature state, at the same time, the de-fogging agent is stored in the storage box 235, the de-fogging agent is quantitatively sent into the inside of the spiral pipe 220 through the control of the quantitative valve 234, and the de-fogging agent adheres to the inner wall of the spiral pipe 220 to form an anti-fogging layer, when the water mist hits the inner wall of the spiral pipe 220, the de-fogging agent can quickly condense the water mist into water droplets;
[0059] The external spray machine is moved to the construction site, the external spray machine is started to spray water mist, the sprayed water mist adsorbs 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 carrying the floating dust and water mist enters the inside of the spiral pipe 220 through the wind collecting cylinder 222, under the guidance of the spiral pipe 220, the airflow forms a cyclone after entering the inside of the spiral pipe 220, under the action of centrifugal force, most of the water mist adsorbing dust hits the inner wall of the spiral pipe 220, so that the water mist is adsorbed on the inner wall of the spiral pipe 220, the temperature of the water mist in the tunnel is higher than the temperature of the inner wall of the high-pressure spiral pipe 220, the water mist meets the de-fogging agent, so that the water mist quickly condenses into water beads, under the action of gravity, the water beads mixed with dust slide down the inside bottom of the spiral pipe 220, finally flow through the sewage pipe 236, the sewage branch pipe 237 and the sewage main pipe 238 and enter the inside of the sewage storage box 239, most of the water mist flows through the inside of the spiral pipe 220 and condenses into water beads and is discharged, so that preliminary filtration is realized, when the dust is filtered by the subsequent filter element 214, only a small amount of water mist is adsorbed on the filter element 214, so that the filtering pressure of the filter element 214 is reduced, the filter element 214 can continuously work, the replacement and cleaning period of the filter element 214 is greatly prolonged, the device can work for a longer time, the filtering efficiency is improved, and the dust that has not been adsorbed by the water mist enters the inside of the spiral pipe 220, and the water mist contacts the dust again under the disturbance of the cyclone, so that the dust is adsorbed, the filtering pressure of the filter element 214 is further reduced, and the continuous working time of the device is further prolonged;
[0060] The remaining dust and a small amount of water mist are filtered through the three filter cartridges 214, and the clean air is discharged from the axial flow fan 210, realizing the filtering of the tunnel air. At the same time, the moving motor 207 also drives the moving gear 208 to rotate back and forth, the moving gear 208 is engaged with the arc-shaped rack 206, and then the moving block 204 moves back and forth in the limiting groove 203, under the driving action of the connection of the lifting frame 205 and the adjusting frame 315, the filtering box 209, the axial flow fan 210 and the condensate tank 211 are driven to move, thereby expanding the range of action of the wind collecting cylinder 222, the dust suction range of the device is increased, the dust removal speed is improved, and the harm of dust to the workers on site is reduced. At the same time, the adjusting electric push rod 318 is started, the adjusting electric push rod 318 drives the adjusting rack 319 to move back and forth, drives the adjusting gear 317 to rotate, and then drives the adjusting shaft 316 to rotate, so that the wind collecting cylinder 222 swings up and down, further expanding the range of action of the wind collecting cylinder 222, further improving the dust removal efficiency, and when the tunnel is excavated, the engineering vehicle can pass through the bottom of the arc-shaped frame 202, without blocking the passage of the engineering vehicle, so that the tunnel construction is more convenient, and the tunnel construction speed is indirectly improved;
[0061] When the dust accumulated on the inside bottom of the spiral pipe 220 is more, the water pump storage tank 229 sends clean water into the water supply main pipe 230, the clean water flows through the water supply branch pipe 231, the water distribution box 232 and the three-way pipe 233 into the inside of the spiral pipe 220, and the inside of the spiral pipe 220 is washed. The water entering the inside of the spiral pipe 220 washes away the dust on the inside bottom of the spiral pipe 220, and finally flows through the sewage pipe 236, the drainage branch pipe 237 and the drainage main pipe 238 into the inside of the sewage storage tank 239 to collect the sewage. The device has a self-cleaning function and does not need to be cleaned manually, reducing the labor intensity;
[0062] In the process of filtering and dust removal, the vibration motor 219 also operates, the vibration motor 219 drives the vibration plate 218 to vibrate, the vibration plate 218 contacts the filter cartridge 214, and under the elastic support action of the vibration spring 215, the vibration motor 219 drives the filter cartridge 214 to vibrate. The vibration of the filter cartridge 214 cooperates with the gravity, and the dust on the surface of the filter cartridge 214 falls into the inside bottom of the filtering box 209 through the dust falling port 217. In the process of filtering and dust removal of the device, most of the dust will not adhere to the surface of the filter cartridge 214, so that the air can quickly pass through the three filter cartridges 214, and the filtering effect is better;
[0063] At the same time, in the process of filtering and dust removal, the air pump 301 sends high-pressure air into the arc-shaped box 302, the high-pressure air is sprayed from the air outlet hole 303, and the sprayed high-pressure gas diffuses to the surrounding to form an air curtain. The air curtain can block the dust from spreading to other positions of the tunnel, protect the working environment on site, and protect the health of workers at other positions of the tunnel;
[0064] When the tunnel is under construction, the mechanical equipment will generate a large amount of heat, causing the temperature inside the tunnel to rise, and the on-site working environment is not suitable. When the temperature of the tunnel is high, the cold end of the refrigeration circulating pump 225 transports cold water to the inside of the condenser tank 211, the surface of the condenser tank 211 is provided with cooling fins, the driving motor 322 and the cold fan 324 are started, the cold fan 324 guides the airflow to pass through the surface of the condenser tank 211, and the low-temperature condenser tank 211 cools the airflow, which is diffused to the surrounding under the guidance of the cold fan 324, thereby reducing the temperature of the on-site working environment and improving the working comfort. The rotating teeth 321 and the driving gear 323 are engaged, the driving motor 322 drives the rotating ring 320 and the cold water fan to swing back and forth, thereby increasing the range of the cold fan 324 and making the cooling speed faster. Meanwhile, the ice blocks are placed in the ice placing frame 326, the air pump 301 discharges high-pressure air to the inside of the arc-shaped box 302, the air inlet end of the air pump 301 is connected to one side of the ice storage box 325, and the air in the air pump 301 flows through the ice storage box 325 to be cooled, so that the air sprayed from the air outlet hole 303 is cold air, which further improves the cooling effect in cooperation with the cold fan 324. The device can also cool the working environment during dust removal, avoid dust diffusion, and provide a comfortable working temperature, thereby further improving the working comfort. Meanwhile, the water generated by the melting of the ice is stored in the inside bottom of the ice storage box 325, and the 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 left on the surface of the filter element 214 and water washing is not required, the on-off valve 305 connected to the gas supply branch pipe 306 is opened, the on-off valve 305 connected to the cleaning branch pipe 307 is closed, the high-pressure gas in the arc-shaped box 302 can flow through the gas supply branch pipe 306, the rotary joint 308, and enter the cleaning spray pipe 309, and finally be sprayed from the cleaning spray hole 310. The high-pressure gas sprayed out can flush away the dust adhered to the surface of the filter element 214. When the filter element 214 needs to be cleaned, the on-off valve 305 connected to the gas supply branch pipe 306 is closed, and the on-off valve 305 connected to the cleaning branch pipe 307 is opened. The water in the water supply main pipe 230 can flow through the cleaning branch pipe 307, the rotary joint 308, and enter the cleaning spray pipe 309, and finally be sprayed from the cleaning spray hole 310 to clean the filter element 214. The swinging electric push rod 312 can drive the cleaning spray pipe 309 to swing, so that the cleaning water or high-pressure air sprayed from the cleaning spray hole 310 has a wider range of action, and manual disassembly and assembly of the filter element 214 for cleaning are not required, which is convenient and fast and further reduces the labor intensity.
[0066] The cold delivery branch pipe 226, the return branch pipe 227, the water delivery branch pipe 231, the water discharge branch pipe 237, the cleaning branch pipe 307 and the dust discharge pipe 314 are all corrugated flexible pipes, and when the filter box 209, the axial flow fan 210 and the condensate tank 211 move, the cold delivery branch pipe 226, the return branch pipe 227, the water delivery branch pipe 231, the water discharge branch pipe 237, the cleaning branch pipe 307 and the dust discharge pipe 314 will not hinder the movement of the filter box 209, the axial flow fan 210 and the condensate tank 211.
