Although the function of continuously absorbing the exhaust gas can be achieved, it is difficult to suck out the exhaust gas adsorbed by the activated carbon by suction. After the activated carbon is saturated with adsorption, new activated carbon is replaced. In addition, during the continuous rotation of the rotor for adsorption, the activated carbon is filled in the adsorption tank and has no fluidity, resulting in a decrease in the adsorption efficiency.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] Before absorbing the exhaust gas, the disc is rotated. Since the limiting columns all slide inside for limiting, and the movable groove is symmetrical and has an arc-shaped structure, the limiting columns are pushed to slide inside when the turntable rotates.

After the exhaust gas passes through the first filter at one end of the bottom trough, it is adsorbed by the activated carbon inside, and the air is output through the second filter. As the turntable rotates indirectly, the baffle rod rotates until it passes the fixed rod, which can rotate the fixed rod. The fixed rod drives the shaft to rotate a certain angle, and the shaft drives the grid plate on the outer wall to rotate in the trough, thereby stirring the activated carbon inside the trough, causing the accumulated activated carbon to stir, thereby improving the exhaust gas adsorption efficiency.

[0024] The fixing seat 1 and the fixing rod 3 are both L-shaped structures. The outer wall of the turntable 301 is provided with gear blocks meshing with the gear 5 at equal angles, so that the blocking rod 309 can be pushed to rotate by the fixing rod 3, and the gear 5 drives the turntable 301 to rotate when rotating.

[0025] The sealing mechanism includes a mounting ring 304 which is fitted on the outer wall of the turntable 301, and the mounting ring 304 covers one end of the material trough 302 facing the fixed rod 3, a positioning post 305 is fixedly arranged at an equal angle on the mounting ring 304 facing the outer wall of the turntable 301, and a positioning hole which fits with the positioning post 305 is opened on the outer wall of the turntable 301, a second filter screen 306 is fixedly arranged on the inner wall of the mounting ring 304, a rotating shaft 307 is rotatably connected at the center of the second filter screen 306, one end of the rotating shaft 307 extends to the inside of the material trough 302, and a grid plate 308 is fixedly arranged on the outer wall of the rotating shaft 307, three groups of baffle rods 309 are fixedly arranged on the outer wall of the other end of the rotating shaft 307 at equal angles, and the baffle rod 309 and the fixed rod 3 are located in the same vertical plane, so as to facilitate the sealing of the material trough 302 filled with activated carbon by the sealing mechanism, and the grid plate 308 rotates in the material trough 302 to stir the activated carbon inside the material trough 302.

[0026] One end of the air hood 6 is attached to the outer wall of the turntable 301 and is located at one end of the material trough 302 facing the support plate 2, and the diameter of the air hood 6 is larger than the diameter of the material trough 302 to prevent the exhaust gas from leaking when it is not adsorbed by the activated carbon in the material trough 302.

[0027] The positioning mechanism includes a central column 9 fixedly arranged on the outer wall at the center of the turntable 301, a sleeve rod 901 is fixedly arranged at an equal angle on the outer wall of the central column 9, a reset spring 902 is fixedly connected to the inner wall of the sleeve rod 901, the end of the reset spring 902 is fixedly connected to the inner rod 903 which slides with the sleeve rod 901, and a limiting column 904 which passes through the top of the sleeve rod 901 is fixedly arranged on the top of the inner rod 903, a limiting groove 905 which slides with the limiting column 904 is provided on the top of the sleeve rod 901, and a card groove 906 which fits with the end of the inner rod 903 is respectively provided on the outer wall of the mounting ring 304, and a disc 907 is rotatably connected to the outer wall of the central column 9, so as to facilitate the disassembly and installation of the sealing mechanism through the positioning mechanism and the replacement of the activated carbon.

[0028] A movable groove 908 is symmetrically opened at the inner center of the disk 907. The movable groove 908 is an arc-shaped structure, and the movable groove 908 is slidably connected to the limiting column 904, so that when the disk 907 rotates, the limiting column 904 is pushed to slide in the limiting groove 905. At this time, the four groups of limiting columns 904 drive the four groups of inner rods 903 to retract inwardly in the four groups of sleeve rods 901.

[0029] Working principle: First, before absorbing the exhaust gas, the disc 907 is rotated. Since the limiting posts 904 are all slid in the limiting grooves 905 for limiting, and the movable grooves 908 are centrally symmetrical and have an arc-shaped structure, the disc 907 pushes the limiting posts 904 to slide in the limiting grooves 905 when it rotates. At this time, the four groups of limiting posts 904 drive the four groups of inner rods 903 to shrink inward in the four groups of sleeve rods 901, and the inner rods 903 squeeze the reset springs 902 respectively, so that the ends of the inner rods 903 move out of the installation. The mounting ring 304 is pulled out of the corresponding positioning hole on the surface of the turntable 301 by the slot 906 on the outer wall of the mounting ring 304, and the positioning column 305 is moved out of the corresponding positioning hole on the surface of the turntable 301, and the capping mechanism can be disassembled, and the activated carbon is filled in the material trough 302. Conversely, the mounting ring 304 is covered on one end of the material trough 302 through the positioning column 305. Under the action of the return spring 902, the end of the inner rod 903 is correspondingly inserted into the slot 906 on the outer wall of the mounting ring 304 to install the capping mechanism, thereby facilitating the replacement of the activated carbon.

[0030] Then, the exhaust gas pipeline is connected to the fan 8. After the fan 8 is started, the exhaust gas is transported from the outlet of the fan 8 to the air pipe 7 and the air hood 6. At the same time, the servo motor 4 is started, and the gear 5 at the output end is indirectly rotated by the servo motor 4. When the gear 5 rotates, the turntable 301 is rotated through the tooth block meshed with the outer wall, and the rotation distance is the same. After each rotation, the air hood 6 can cover one end of the material trough 302. Then, the exhaust gas passes through the first filter screen 303 at one end of the bottom material trough 302 and then passes through the inner The activated carbon is adsorbed, and the air is output through the second filter screen 306. As the turntable 301 rotates indirectly, the blocking rod 309 rotates until it passes the fixed rod 3, which can make the fixed rod 3 rotate. The fixed rod 3 drives the rotating shaft 307 to rotate a certain angle, and the rotating shaft 307 drives the grid plate 308 of the outer wall to rotate in the material trough 302, thereby stirring the activated carbon inside the material trough 302, so that the accumulated activated carbon is stirred, thereby improving the exhaust gas adsorption efficiency. The activated carbon can be replaced after being used for a period of time.
