[0002] Asphalt mixing production usually requires the following steps: After a period of mixing in the mixing tank, the finished asphalt material is generated. The mixing tank door is opened to put the finished asphalt material into the collection hopper. The collection hopper is opened to put the finished asphalt material into the transport truck. The transport truck transports the finished material to the paver for road paving. Among them, when the collection hopper is opened and the finished asphalt material is put into the transport truck, a large amount of asphalt fume will be generated. If it is directly discharged into the atmosphere, it will cause atmospheric pollution.

Specifically, the smoking device 4 includes a shell 42 fixedly provided at the bottom of the construction platform 1. A dust filter cartridge 41 is fixedly provided on the inner wall of the shell 42. The horizontal cross-section of the dust filter cartridge 41 gradually increases from top to bottom, which can prevent the asphalt concrete poured out from the discharge port of the supply hopper 3 from sticking to the surface of the dust filter cartridge 41 and blocking the dust filter holes. An annular suction chamber is formed between the shell 42 and the dust filter cartridge 41. The discharge port at the bottom end of the supply hopper 3 is located inside the annular suction chamber. The annular suction chamber can form a negative pressure area near the discharge port of the supply hopper 3 when inhaling, so as to prevent the asphalt fume from the discharge port of the supply hopper 3 from escaping over a large range, thereby reducing the smoking efficiency.

[0026] Four circumferentially spaced partitions 43 are fixedly provided between the shell 42 and the dust filter cartridge 41, and the four partitions 43 divide the annular suction chamber into four suction chambers; the front and rear sides of the shell 42 are respectively fixedly connected and communicated with the first connecting pipe 9, the left and right sides of the shell 42 are respectively fixedly connected and communicated with the second connecting pipe 10, the end of the second connecting pipe 10 away from the shell 42 is fixedly connected and communicated with the first connecting pipe 9, and the end of the first connecting pipe 9 away from the shell 42 is fixedly connected and communicated with the flue gas duct 5; by evenly dividing the annular suction chamber into four suction chambers, and connecting the four suction chambers with the flue gas duct 5 through the first connecting pipe 9 and the second connecting pipe 10, the four suction chambers can evenly absorb asphalt smoke from four directions, thereby improving the smoking efficiency.

[0027] One end of the flue gas duct 5 away from the shell 42 is fixedly connected and communicated with a bag-type dust collector 8. The bag-type dust collector 8 can filter dust particles carried in the asphalt flue gas. Specifically, the air outlet of the bag-type dust collector 8 is fixedly connected and communicated with an activated carbon purifier 6 through the flue gas duct 5.

[0028] The top of the cylindrical shell 61 is fixedly connected and communicated with a feed barrel 67, which corresponds to multiple activated carbon bins up and down. A box door 68 is hinged on the feed barrel 67, so that after opening the box door 68, the activated carbon can quickly enter the activated carbon bin through the feed barrel 67, thereby achieving the purpose of quickly replacing the activated carbon; the bottom of the cylindrical shell 61 is fixedly connected and communicated with a bottom shell 65, and a collecting box 66 with an upper opening structure is slidably provided in the bottom shell 65, so that when the activated carbon bin is driven to rotate by the rotating circular plate 62 and the mesh plate 63, the activated carbon can be quickly unloaded into the collecting box 66 located below the activated carbon bin under the action of gravity; the front end of the collecting box 66 can pass through the bottom shell 65, so that the collecting box 66 can be moved out of the activated carbon purifier 6 to recycle and reuse the waste activated carbon.

[0029] A locking member for fixing the circular plate 62 is provided on the circular plate 62. Specifically, the rear end of the cylindrical shell 61 is provided with two first sockets which are spaced apart from each other on the left and right and are transparent from front to back. The circular plate 62 located at the rear is provided with two second sockets which are spaced apart from each other on the left and right and are transparent from front to back. The first socket can correspond to the second socket front to back, and when the first socket corresponds to the second socket front to back, the activated carbon bin is at an upper opening or a lower opening. The locking member includes a pin 69 which is slidably penetrated through the first socket and the second socket.

After being filtered by the activated carbon, the filtered asphalt fume is discharged through the outlet of the suction fan through the outlet pipe 7.

[0032] When the activated carbon needs to be replaced, remove the latch 69, move the mesh plate 63 to drive the circular plate 62 to rotate 180°, rotate the activated carbon bin with the opening facing upward and filled with waste activated carbon to the opening facing downward, and the activated carbon enters the collection box 66 under the action of gravity. At the same time, rotate the empty activated carbon bin with the opening facing downward to the opening facing upward, open the box door 68, pour new activated carbon into the feeding barrel 67, and the new activated carbon automatically enters the activated carbon bin under the action of gravity, and then insert the latch 69 into the first socket and the second socket to complete the replacement of the activated carbon.
