[0026] One end of the clamping plate 42 is fixedly connected to the control frame 6 , and one side of the control frame 6 is fixedly connected to the handle 7 .

[0027] A coarse filter 8 is disposed on the inner side of the fixing frame 43 , a fine filter 9 is disposed on the bottom of the storage frame 45 , and an activated carbon box 10 is disposed on the inner side of the storage frame 45 .

[0028] It should be noted that after the flue gas is filtered by the coarse filter 8, it is filtered again under the action of the fine filter 9 to improve the particle filtering effect. After passing through the fine filter 9, the flue gas is adsorbed and purified by the activated carbon box 10, effectively reducing the direct emission of harmful substances in the flue gas into the atmosphere. When it is necessary to clean and replace the filter component, the control frame 6 is pulled by the handle 7, so that the card plate 42 slides under the limit of the motion guide groove 41, and then the fixed frame 43, the storage frame 45, etc. are pulled out of the outside of the fixed shell 1, and the connection between the card plate 42 and the fixed frame 43 is loosened by bolts, so as to facilitate the cleaning of the coarse filter 8 and the fine filter 9. Under the action of the storage frame 45, it is convenient to carry the activated carbon box 10, to check the adsorption saturation state of the activated carbon box 10, and to directly take out and replace the activated carbon box 10. The operation is simple and convenient, which is conducive to regular cleaning and maintenance to ensure the flue gas filtering effect.

[0029] refer to Figure 1 , Figure 4 and Figure 5 As shown, the smoke exhaust assembly 5 is arranged on the inner side of the support frame 3, and the smoke exhaust assembly 5 includes a support rod 51, a baffle 52 and a positioning rod 53.

[0035] It should be noted that the smoke exhaust pipe 17, the support frame 3, the connecting cover 2, the fixed shell 1 and the interior of the hot air rotary furnace 19 are in a connected state. Driven by the motor 14, the connecting rod 13 drives the threaded rod 12 to rotate under the support of the support frame 3, so that the threaded rod 12 drives the positioning block 11 to move, and then drives the rack 55 to move. Under the meshing action of the gear 54 and the rack 55, and under the connection of the positioning rod 53, the gear 54 drives the baffle 52 to move, and the support rod 51 supports the baffle 52 so that the support rod 51 rotates in the connecting hole 15, which is convenient for controlling the opening and closing of the baffle 52. When smoke exhaust is not needed, the baffle 52 is controlled to be closed, so that the smoke exhaust pipe 17 is not connected with the support frame 3, the connecting cover 2, the fixed shell 1 and the interior of the hot air rotary furnace 19, effectively preventing external dust and impurities from entering the hot air rotary furnace 19.

[0036] The working principle of a smoke exhaust device provided by the utility model is as follows:

[0037] When in use, the flue gas in the hot air rotary furnace 19 is filtered through the coarse filter 8 to filter out larger impurities, and the fine filter 9 is used to filter out fine particles in the flue gas. The flue gas is adsorbed and purified by the activated carbon box 10, and the filtered flue gas is detected in real time under the action of the flue gas analyzer 16. When the flue gas meets the emission standard, the smoke exhaust fan 18 is used to make the smoke exhaust gas be discharged through the support frame 3 and the smoke exhaust pipe 17. When it does not meet the emission standard, the smoke exhaust fan 21 is used to draw the smoke into the connecting pipe 20, and transport it to the inside of the fixed shell 1 through the conveying pipe 22, so as to facilitate filtering again, effectively reducing the impurity particles and harmful substances in the smoke from being discharged into the atmosphere, and pulling the handle 7 allows the control frame 6 to drive the card plate 42 to slide under the limit of the motion guide groove 41, and then under the connection of the fixed frame 43, the coarse filter 8 and the fine filter 9 are connected to the fixed frame 43. The storage frame 45 is pulled out of the fixed shell 1, which is convenient for cleaning the coarse filter screen 8 and the fine filter screen 9, and for checking and replacing the activated carbon box 10 inside the storage frame 45. The operation is simple and convenient to ensure the filtering effect. Under the drive of the motor 14, the connecting rod 13 drives the threaded rod 12 to rotate, and then the positioning block 11 drives the rack 55 to move. Under the connection of the positioning rod 53 and the support rod 51, the gear 54 drives the baffle 52 to rotate, which is convenient to control the opening and closing, and is convenient to adjust the connection between the smoke exhaust pipe 17 and the hot air rotary furnace 19 according to needs. When smoke exhaust is needed, the baffle 52 is controlled to be in an open state, so that the smoke exhaust pipe 17 and the inside of the hot air rotary furnace 19 are unobstructed. When not in use, the baffle 52 is controlled to be closed, which effectively prevents external impurities from entering the hot air rotary furnace 19 through the smoke exhaust pipe 17, reduces dust accumulation, and has strong flexibility and practicality.
