In the process of metal heat treatment, a large amount of waste gas will be generated, and a purifier is needed to treat the generated waste gas. For example, a waste gas purifier for metal heat treatment with the publication number "CN219091466U" is set to press the worm gear downward to release the meshing of the worm gear and the worm, so that the position of the gear teeth and the transmission rod can be adjusted more quickly and effectively, so that the transmission rod can quickly and effectively drive the slider and the locking block to move. Subsequently, only the worm gear needs to be loosened, and then the rotating wheel can be rotated to make the worm gear stably drive the first rotating shaft and the transmission gear to rotate, so that the locking block can quickly and stably fix and release the cover plate, and the activated carbon plate can be installed and maintained without tools, which greatly improves the practicality of the purifier. However, the waste gas purifier still has the following disadvantages in actual use:

[0003] When the above mechanism is in use, it is not convenient to reuse the waste heat in the exhaust gas, resulting in a waste of heat resources.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0030] Embodiment 1: In order to solve the problem that it is inconvenient to reuse the waste heat in the exhaust gas in the prior art, resulting in a waste of heat resources, the following solution is disclosed. Figure 1-Figure 3 As shown, it includes a treatment box 1, an air inlet pipe 2 is fixed on the left side of the treatment box 1, and an air outlet pipe 3 is arranged on the right side of the treatment box 1, so that the exhaust gas enters the treatment box 1 from the air inlet pipe 2 and is purified and then discharged from the air outlet pipe 3;

[0031] It also includes: a heat exchange structure is arranged inside the treatment box 1, and the waste heat in the exhaust gas is used to heat the cold water inside the heat exchange tube 5, thereby avoiding the waste of heat energy in the exhaust gas. The heat exchange structure includes a heat exchange tube 5 fixed on the left side of the treatment box 1, and both ends of the heat exchange tube 5 pass through the inside of the treatment box 1. The upper and lower ends of the left side of the treatment box 1 are fixed with spoilers 4 at equal intervals. The upper part of the treatment box 1 is rotatably connected with a transmission rod 8, and the outer side of the left end of the transmission rod 8 is sleeved and fixed with a cam 9. The heat exchange tube 5 is rough. The surface of the heat exchange tube 5 is arranged, and the heat exchange tube 5 is elastic and made of TPE material. The cam 9 contacts the heat exchange tube 5 after rotating. The motor is installed on the top of the processing box 1 on the right side of the liquid storage box 6, and the output end of the motor is connected to the rotating rod 13. The inside of the processing box 1 is located at the right end of the transmission rod 8 with a shell 12 fixed thereto. The bottom of the rotating rod 13 extends into the inside of the shell 12, and the right end of the transmission rod 8 extends into the inside of the shell 12. The right end of the transmission rod 8 is connected to the bottom of the rotating rod 13 through a bevel gear set.

[0032] When in use, the exhaust gas first enters the treatment box 1 through the intake pipe 2, and then the waste heat in the exhaust gas can be used to heat the cold water in the heat exchange tube 5, so that the waste heat in the exhaust gas can be reused to avoid wasting heat energy. At this time, the spoiler 4 can slow down the speed of exhaust gas circulation, so that the heat in the exhaust gas can fully heat the cold water in the heat exchange tube 5. At the same time, a large amount of dust in the exhaust gas can be adsorbed through the surface of the heat exchange tube 5. Then start the motor, and the motor drives the rotating rod 13 to rotate. At the same time, the rotating rod 13 drives the transmission rod 8 to rotate using the bevel gear set, so that the transmission rod 8 drives the cam 9 to rotate, and can reciprocately knock on the surface of the heat exchange tube 5 to let the dust adsorbed on its surface fall off.

[0033] Embodiment 2: Different from Embodiment 1, this embodiment can spray and purify the waste gas. Figure 1 and Figure 5 As shown, a liquid storage box 6 is fixedly connected to the top of the processing box 1, and a liquid filling port is opened on the left side of the top of the liquid storage box 6. A pipe 7 is installed inside the processing box 1 below the transmission rod 8, and nozzles are fixedly installed at equal intervals at the bottom of the pipe 7, and the pipe 7 is connected to the inside of the liquid storage box 6;

[0034] The spray liquid can be added to the liquid storage box 6 through the provided liquid filling port, and then the spray liquid in the liquid storage box 6 enters the pipe 7, and then the spray liquid in the pipe 7 is sprayed into the exhaust gas through the nozzle, thereby preliminarily purifying the exhaust gas.

[0035] Embodiment 3: Different from Embodiment 1 and Embodiment 2, this embodiment can automatically clean the surface of the activated carbon plate 11 to improve work efficiency. Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a cleaning structure is provided on the right side of the processing box 1, and a belt drive is used to realize the rotation of the cleaning brush 15 and clean the surface of the activated carbon plate 11, thereby preventing the activated carbon plate 11 from being blocked and affecting the filtering effect. The cleaning structure includes an activated carbon plate 11 installed on the right side of the processing box 1, and a fixed plate 10 is fixedly connected to the left side of the activated carbon plate 11 inside the processing box 1, and a cross bar 14 is connected to the inside of the fixed plate 10, and the right end of the cross bar 14 is connected to the left side bearing of the activated carbon plate 11, and the outer side of the left end of the cross bar 14 is connected to the outer side of the right end of the transmission rod 8 through a pulley assembly. A cleaning brush 15 is sleeved and installed on the outer side of the right end of the rod 14, and the brush part of the cleaning brush 15 contacts the surface of the activated carbon plate 11. The left sides of the two cleaning brushes 15 are fixedly connected with a bracket 16, and a striking block 17 is slidably connected to the inside of the bracket 16. Magnets 18 are installed correspondingly between the left end of the striking block 17 and the right side of the fixed plate 10. A return spring 19 is symmetrically installed between the side surface of the right end of the striking block 17 and the inner wall of the bracket 16. The magnetic properties of the opposite surfaces of the two magnets 18 are the same. The striking block 17 is arranged in a "T" shape, and the right end of the striking block 17 contacts the surface of the cleaning brush 15.

[0036] The waste gas after spraying passes through the activated carbon plate 11, and the activated carbon plate 11 can filter the large particles of impurities in the waste gas, further purify the waste gas, and then the purified waste gas is discharged from the exhaust pipe 3. At the same time, the transmission rod 8 uses the pulley assembly to drive the cross bar 14 to rotate synchronously, so that the cross bar 14 drives the cleaning brush 15 to rotate and clean the surface of the activated carbon plate 11 to prevent the activated carbon plate 11 from being blocked by impurities and affecting the filtering effect. Then, when the cleaning brush 15 drives the bracket 16 to move to the fixed When the magnet 18 is on the plate 10, due to the principle that like-charged magnets 18 repel each other, the striking block 17 moves and strikes the side of the cleaning brush 15 (at this time the return spring 19 is in a compressed state). When the striking block 17 originally fixes the position of the magnet 18 on the plate 10, the striking block 17 is reset under the elastic force of the return spring 19, and the above operation is repeated, so that the striking block 17 strikes the side of the cleaning brush 15 back and forth, thereby shaking off impurities on the surface of the cleaning brush 15, thereby improving the subsequent cleaning effect of the cleaning brush 15.
