[0050] Further, such as Figure 1 and Figure 6 As shown, first support wheels 405 are installed on both sides of the bottom of the transmission block 404 and both sides of the top of the connecting seat 401. The first support wheel 405 at the bottom of the transmission block 404 contacts the top of the base 2, and the first support wheel 405 at the top of the connecting seat 401 contacts the bottom of the support plate 406. The setting of the first support wheel 405 can improve the bearing capacity of the support plate 406.

[0051] A second support wheel 412 is fixedly mounted on one side of the bottom of the support plate 406 . The second support wheel 412 is used to contact the support plane at the bottom of the base 2 . The second support wheel 412 can support the support plate 406 in one step.

[0052] Further, such as Figure 1 As shown, a support frame 408 is fixedly installed on the top of the support plate 406, and the collecting part includes a recovery box 409 inserted and connected in the support frame 408, and a sealing ring 410 is fixedly installed on the top of the recovery box 409, and one of the sealing rings 410 in the collecting part contacts the bottom of the processing box 1, and the sealing ring 410 is used for sealing between the recovery box 409 and the processing box 1.

[0055] Furthermore, a pressure sensor is provided in the processing box 1 , and the pressure sensor is connected to a controller, and the controller is connected to the first solenoid valve 102 , the air intake fan 104 , the water pump 111 , the transmission pipe 413 , the motor 403 and the drain pipe 414 .

[0056] The use process of the smoke recovery structure of the asphalt mixing station provided by the utility model is as follows:

[0057] The water pump 111 delivers the water in the water tank 3 to the atomizing nozzle 110 through the water inlet pipe 109 and the second round pipe 108, and then the atomizing nozzle 110 atomizes the water in the treatment box 1. The flue gas is delivered to the outlet pipe 106 through the first round pipe 105 from the air inlet pipe 103, and then discharged to the treatment box 1 through the outlet pipe 106. The flue gas and water contact in the treatment box 1, so that the flue gas and water can be fully clamped out, so that the tar mist in the flue gas can be recovered, and the recovered water and tar fall into the recovery box 409. In this process, the pressure sensor detects the pressure in the treatment box 1. When the air pressure in the treatment box 1 is too high, the first solenoid valve 102 is opened so that the air pressure in the treatment box 1 is discharged from the exhaust pipe 101.

[0058] After tar and water are collected in the recovery box 409, the water pump 111 and the air intake fan 104 are stopped, and the hydraulic cylinder 411 drives the recovery box 409 directly below the treatment box 1 to descend, and then the motor 403 drives the support plate 406 to move through the screw rod 402 and the transmission block 404, so that another recovery box 409 moves to the bottom of the treatment box 1. At this time, the hydraulic cylinder 411 under the recovery box 409 pushes it up, and makes the sealing ring 410 on the top contact with the treatment box 1, and then the smoke recovery continues;

[0059] At the same time, the recovery tank 409 containing water and tar is moved from under the treatment tank 1 and the corresponding drain pipe 414 is aligned with the water receiving box 302. The corresponding second solenoid valve is opened so that the water in the recovery tank 409 is discharged from the drain pipe 414 and the water receiving box 302 to the filter box 301, and then flows back to the water tank 3 after being filtered by the filter box 301. After the water is discharged, the delivery pump on the transmission pipe 413 is turned on to discharge the tar from the transmission pipe 413.
