As the filter screen 5 moves upward, the filter screen 5 drives the second iron block 55 and the filter bucket 49 to move upward synchronously through the second magnet block 57. The second tension spring 60 is in a tensioned state. When the second magnet block 57 and the second iron block 55 move up to a preset height, the bottom horizontal position of the impurity discharge pipe 50 is higher than the top horizontal position of the support plate 47. Due to the increase in the pulling force applied by the second tension spring 60 to the second supporting portion 58, the magnetic force applied by the second magnet block 57 to the second iron block 55 is less than the downward pulling force on the second iron block 55. The second tension spring 60 drives the second supporting portion 58 and the filter bucket 49 to move downward, and the bottom end of the impurity discharge pipe 50 is inserted into the through hole 62 again. When the support portion 58 and the stop column 61 come into contact, the filter hopper 49 stops moving downward, and the instantaneous impact force causes the impurities blocked on the filter hopper 49 to be shaken off, and the impurities fall into the collection box 63 through the impurity discharge pipe 50 and the through hole 62. When it is necessary to move the filter hopper 49 and the impurity discharge pipe 50 located at the collection station to just below the support hopper 2, the filter screen 5 drives the second iron block 55 and the filter hopper 49 to move upward synchronously through the second magnet block 57, and the second tension spring 60 is in a stretched state, so that the bottom horizontal position of the impurity discharge pipe 50 is higher than the top horizontal position of the support plate 47, and the bottom end of the impurity discharge pipe 50 is pulled out of the through hole 62, and then the third rotating shaft 52 is driven to rotate by the servo motor 53. When the rotating frame 51 drives the filter hopper 49 and the second iron block 55 to rotate synchronously,The second iron block 55 is no longer located directly below the second magnet block 57, and the second magnet block 57 no longer applies magnetic force to the second iron block 55. The second tension spring 60 drives the second support portion 58 and the filter bucket 49 to move downward so that the bottom end of the impurity discharge pipe 50 is again in close contact with the top of the support plate 47. With the continuous rotation of the rotating frame 51, the filter bucket 49 and the impurity discharge pipe 50 located at the collection station can be moved to directly below the support bucket 2. When it is necessary to clean the impurities in the collection box 63, the staff drives the second bolt 67 to rotate so that the second bolt 67 is disengaged from the separation box 1 and the fixing of the sealing cover 69 is released. The staff drives the sealing cover 69 to move so that the sealing cover 69 drives the collection box 63 to be pulled out of the separation box 1 through the second connecting column 66, and the second guide block 65 slides out of the second guide groove 64, so that the impurities in the collection box 63 can be cleaned, and the rectangular hole 68 is open at this time, and the staff can add or replace the spray water into the separation box 1 through the rectangular hole 68.

[0024] A modified asphalt waste gas treatment method of this embodiment uses the modified asphalt waste gas treatment device as described above, and includes the following steps: Step 1: The exhaust gas enters the support bucket 2 through the air inlet pipe 3, and the exhaust gas is filtered through the filter screen 5; Step 2: The staff injects water into the separation box 1 through the exhaust pipe 4, and the water supply device pumps the water in the separation box 1 into the connecting shell 11. The water then enters the support pipe 9 through the water inlet pipe 8, and the water enters the nozzle 12 through the liquid outlet pipe 13 and the hose 14. Finally, the nozzle 12 sprays the water out; Step 3: The hydraulic telescopic rod 6 drives the movable ring 15 to reciprocate in the vertical direction, and the movable ring 15 drives the first tooth plate 16 to move. The first tooth plate 16 drives the first rotating shaft 17 and the first bevel gear 19 to rotate forward and reverse periodically through the first gear 18. The first bevel gear 19 can drive the second bevel gear 20 and the water inlet pipe 8 to rotate forward and reverse periodically. The water inlet pipe 8 drives the nozzle 12 to revolve around the water inlet pipe 8 through the support pipe 9, so that the nozzle 12 swings. The nozzle 12 sprays water above the filter screen 5, and the water removes the impurities still remaining in the filtered exhaust gas. The water with impurities flows into the support bucket 2 through the filter screen 5; Step 4: The filter 5 is rinsed with water, and the impurity shaking-off structure drives the filter 5 to shake, so as to rinse and shake off the impurities blocked at the bottom of the filter 5; Step 5: Impurities and water flow through the support bucket 2 to the impurity collecting mechanism, and the impurities are collected by the impurity collecting mechanism.

[0025] Working principle: During operation, the exhaust gas enters the support bucket 2 through the air inlet pipe 3, and the exhaust gas is filtered through the filter 5. At the same time, the rotating spray assembly sprays water above the filter 5. The water removes the impurities remaining in the filtered exhaust gas, and the water with impurities flows into the support bucket 2 through the filter 5. At the same time, the water rinses the filter 5, and the impurity shaking-off structure drives the filter 5 to shake, and the impurities blocked at the bottom of the filter 5 are rinsed and shaken off. The impurities and water flow to the impurity collecting mechanism through the support bucket 2, and the impurities are collected by the impurity collecting mechanism. The impurities remaining in the filtered exhaust gas can be removed, and the impurities of the exhaust gas produced by the modified asphalt experiment can be effectively collected and processed, reducing the pollution to the environment in the laboratory. At the same time, the filter 5 can be cleaned for easy use. Water can be injected into the separation box 1 through the exhaust pipe 4, and the water pump 44 is started. The water pump 44 pumps the water in the separation box 1 into the connecting shell 11 through the discharge pipe 43, the first connecting pipe 45 and the second connecting pipe 46. The water then enters the support pipe 9 through the water inlet pipe 8, and the water enters the nozzle 12 through the liquid outlet pipe 13 and the hose 14. Finally, the nozzle 12 sprays the water out. At the same time, the hydraulic telescopic rod 6 drives the movable ring 15 to reciprocate in the vertical direction. The movable ring 15 drives the first gear plate 16 to move. The first gear plate 16 drives the first rotating shaft 17 and the first bevel gear 19 to periodically rotate forward and reverse through the first gear 18. The first bevel gear 19 can drive the second bevel gear 20 and the water inlet pipe 8 to periodically rotate forward and reverse. The water inlet pipe 8 drives the nozzle 12 to revolve around the water inlet pipe 8 through the support pipe 9 to make the nozzle 12 swing. At the same time, the water inlet pipe 8 drives the fixed ring 10 rotates synchronously, the fixed ring 10 drives the first guide block 33 to slide in the annular groove 32 through the prism 31, and since the movable ring 15 reciprocates in the vertical direction, the movable ring 15 can drive the prism 31 to reciprocate in the vertical direction through the first guide block 33, and the prism 31 pulls the movable plate 25 to reciprocate relative to the control box 21 through the connecting rope 30, and the movable plate 25 slides relative to the guide plate 28, and the first tension spring 29 is in a tensioned state, and the first tension spring 29 applies tension to the movable plate 25, so that the connecting rope 30 is always in a taut state, and the movable plate 25 can drive the second gear 24 and the second rotating shaft 23 to rotate forward and reversely through the second tooth plate 26, and the second rotating shaft 23 drives the sprinkler 12 to rotate, and when the sprinkler 12 revolves around the water inlet pipe 8, the inclination angle of the sprinkler 12 can be changed, so that the sprinkler 12 can spray water toward different positions; When it is necessary to drive the filter screen 5 to shake in the vertical direction, the staff fixes the piston plate 40 and the lifting frame 38 together through the first bolt 41. When the movable ring 15 reciprocates in the vertical direction, the movable ring 15 drives the lifting frame 38 to move synchronously. When the lifting frame 38 moves down, the lifting frame 38 drives the first magnet block 42 to move down synchronously through the piston plate 40. When the first magnet block 42 drops to the lowest position, the first magnet block 42 contacts the first iron block 37. When the movable ring 15 and the lifting frame 38 move up, the first magnet block 42 is driven by magnetic force. The movable first iron block 37 and the filter screen 5 move upward synchronously, and the compression spring 36 is in a compressed state. When the movable ring 15 and the lifting frame 38 move upward to the preset position, the pressure exerted by the compression spring 36 on the filter screen 5 increases, resulting in the magnetic force exerted by the first magnet block 42 on the first iron block 37 being smaller than the downward pulling force on the first iron block 37. The compression spring 36 drives the filter screen 5 to move downward, and finally the first iron block 37 contacts the first supporting portion 35, and the filter screen 5 stops moving downward. The instantaneous impact force causes the impurities at the bottom of the filter screen 5 to fall into the supporting bucket 2; Impurities and water enter a filter hopper 49 located directly below the support hopper 2 through the support hopper 2, and impurities are filtered out through the filter hopper 49. The filtered water can be recycled through the rotating spray assembly, and the impurities remain in the impurity discharge pipe 50. The second tension spring 60 is initially in a tensioned state. The second tension spring 60 applies a pulling force to the second support portion 58 and the filter hopper 49 so that the bottom end of the impurity discharge pipe 50 and the top of the support plate 47 are tightly attached to prevent impurities from flowing out of the connection between the impurity discharge pipe 50 and the support plate 47. When it is necessary to collect impurities in the impurity discharge pipe 50, the servo motor 53 drives the third rotating shaft 52 and the rotating frame 51 to rotate, so that a filter hopper 49 located directly below the support hopper 2 moves to the collection station, and the other filter hopper 4 9 and the impurity discharge pipe 50 move to the bottom of the support bucket 2, and the impurity discharge pipe 50 located at the collection station is located above the through hole 62. Since the second tension spring 60 is in a stretched state, the second tension spring 60 applies a downward pulling force to the second support portion 58 and the filter bucket 49 to move the filter bucket 49 and the impurity discharge pipe 50 downward. The bottom end of the impurity discharge pipe 50 is inserted into the through hole 62, and the bottom of the second support portion 58 is in contact with the top of the stop column 61. The filter bucket 49 automatically stops after descending to the preset position, and the impurities in the impurity discharge pipe 50 enter the collection box 63 through the through hole 62. When the filter screen 5 reciprocates in the vertical direction, the filter screen 5 drives the second magnet block 57 to move synchronously through the piston column 56. When the filter screen 5 and the second magnet block 57 descend to the lowest position When the filter screen 5 is in the low position, the second magnet block 57 contacts with the second iron block 55 located at the collecting position. As the filter screen 5 moves upward, the filter screen 5 drives the second iron block 55 and the filter bucket 49 to move upward synchronously through the second magnet block 57. The second tension spring 60 is in a tensioned state. When the second magnet block 57 and the second iron block 55 move up to a preset height, the bottom horizontal position of the impurity discharge pipe 50 is higher than the top horizontal position of the support plate 47. Due to the increase in the pulling force applied by the second tension spring 60 to the second supporting portion 58, the magnetic force applied by the second magnet block 57 to the second iron block 55 is less than the downward pulling force on the second iron block 55. The second tension spring 60 drives the second supporting portion 58 and the filter bucket 49 to move downward, and the bottom end of the impurity discharge pipe 50 is inserted into the through hole 62 again. When the support portion 58 and the stop column 61 come into contact, the filter hopper 49 stops moving downward, and the instantaneous impact force causes the impurities blocked on the filter hopper 49 to be shaken off, and the impurities fall into the collection box 63 through the impurity discharge pipe 50 and the through hole 62. When it is necessary to move the filter hopper 49 and the impurity discharge pipe 50 located at the collection station to just below the support hopper 2, the filter screen 5 drives the second iron block 55 and the filter hopper 49 to move upward synchronously through the second magnet block 57, and the second tension spring 60 is in a stretched state, so that the bottom horizontal position of the impurity discharge pipe 50 is higher than the top horizontal position of the support plate 47, and the bottom end of the impurity discharge pipe 50 is pulled out of the through hole 62, and then the third rotating shaft 52 is driven to rotate by the servo motor 53. When the rotating frame 51 drives the filter hopper 49 and the second iron block 55 to rotate synchronously,The second iron block 55 is no longer located directly below the second magnet block 57, and the second magnet block 57 no longer applies magnetic force to the second iron block 55. The second tension spring 60 drives the second support portion 58 and the filter bucket 49 to move downward so that the bottom end of the impurity discharge pipe 50 is again in close contact with the top of the support plate 47. With the continuous rotation of the rotating frame 51, the filter bucket 49 and the impurity discharge pipe 50 located at the collection station can be moved to directly below the support bucket 2. When it is necessary to clean the impurities in the collection box 63, the staff drives the second bolt 67 to rotate so that the second bolt 67 is disengaged from the separation box 1 and the fixing of the sealing cover 69 is released. The staff drives the sealing cover 69 to move so that the sealing cover 69 drives the collection box 63 to be pulled out of the separation box 1 through the second connecting column 66, and the second guide block 65 slides out of the second guide groove 64, so that the impurities in the collection box 63 can be cleaned, and the rectangular hole 68 is open at this time, and the staff can add or replace the spray water into the separation box 1 through the rectangular hole 68.
