[0024] In this embodiment, please refer to Figure 3-4 The installation and disassembly component 6 includes a displacement plate 61, the outer side of the displacement plate 61 is movably connected to the inner wall of the installation hole 25, the top of the displacement plate 61 is fixedly connected to a rubber column 62, the top of the displacement plate 61 is located on the outer side of the rubber column 62 and is fixedly connected to a spring 63, the top of the rubber column 62 is fixedly connected to a linkage plate 64, the top of the linkage plate 64 is fixedly connected to a lifting rod 65, the outer side of the lifting rod 65 is fixedly connected to a limiting block 66, the top of the lifting rod 65 is located in the inner cavity of the filter bin 21 and contacts with the bottom of the activated carbon plate 23.

[0025] In this embodiment, please refer to Figure 2The interior of the cooling bin 3 is filled with coolant, and two heat sinks 5 are fixedly installed on one side of the cooling bin 3. The main body of the exhaust pipe 4 is located in the inner cavity of the cooling bin 3, which is beneficial for the high-temperature exhaust gas to be cooled by the coolant in the cooling bin 3 when passing through the exhaust pipe 4, and the coolant is cooled by the heat sink 5, so that the temperature of the exhaust gas will drop after entering the purification device 2 through the exhaust pipe 4.

[0026] In this embodiment, please refer to Figure 3 The outer side of the filter bin 21 is movably connected with a sealing sleeve 26 at the installation opening 22, and the inner wall of the sealing sleeve 26 transitionally cooperates with the outer side of the filter bin 21, which is beneficial for blocking the installation opening 22 when the sealing sleeve 26 is sleeved on the outer side of the filter bin 21, thereby preventing exhaust gas from leaking through the installation opening 22.

[0027] In this embodiment, please refer to Figure 4 A number of lower displacement blocks 611 are fixedly connected to the top outer edge of the displacement plate 61, and a number of upper displacement blocks 641 are fixedly connected to the bottom outer edge of the linkage plate 64. The number of lower displacement blocks 611 is the same as the number of upper displacement blocks 641 and they are staggered with each other, which is beneficial for applying pressure to the displacement plate 61 when the upper displacement blocks 641 and the lower displacement blocks 611 are squeezed against each other, so that the displacement plate 61 will rotate slightly.

[0028] In this embodiment, please refer to Figure 3-4 A fixing plate 67 is fixedly connected to the top of the inner cavity of the mounting hole 25, and a limiting groove 68 is provided on the surface of the fixing plate 67, and the inner wall of the limiting groove 68 is adapted to the outer edge of the limiting block 66, which is conducive to passing through the limiting groove 68 when the limiting block 66 rotates slightly, and cannot pass through the limiting groove 68 after the limiting block 66 rotates slightly again.

[0029] Working principle of this utility model:

[0030] Step 1. In the utility model, when the activated carbon plate 23 needs to be replaced, the sealing sleeve 26 is removed from the outer side of the filter bin 21, and then the activated carbon plate 23 is pressed by external force, so that the lifting rod 65 is pressed downward, and the linkage plate 64 is pushed downward by the lifting rod 65, and the rubber column 62 and the spring 63 are squeezed to deform. When the linkage plate 64 moves downward, the upper displacement block 641 and the lower displacement block 611 are squeezed against each other. Since the upper displacement block 641 and the lower displacement block 611 are misaligned with each other, the displacement plate 61 is slightly rotated, and the rubber column 62 drives the linkage plate 64 to rotate through the rotation of the displacement plate 61. When the linkage plate 64 rotates, the lifting rod 65 drives the limit block 66 to rotate slightly. When the limit block 66 rotates slightly, it can pass through the limit groove 68. At this time, the pressing of the activated carbon plate 23 is stopped, so that the spring 63 loses the pressure and recovers. The lifting rod 65 is then pushed up to restore the state, and the linkage plate 64 is lifted up to move it upward. The lifting rod 65 is moved upward by the linkage plate 64 moving upward. At this time, the limit block 66 can pass through the limit groove 68, thereby increasing the travel distance of the lifting rod 65, so that the lifting rod 65 continues to move upward, thereby lifting the activated carbon plate 23, so that the top of the activated carbon plate 23 is out of the installation opening 22, so that the activated carbon plate 23 can be taken out of the inner cavity of the filter chamber 21. During installation, the activated carbon plate 23 is placed into the inner cavity of the filter chamber 21 through the installation opening 22, and the activated carbon plate 23 is pressed again, so that the lifting rod 65 pushes the linkage plate 64 to move downward, so that the limit block 66 rotates slightly again, so that the limit block 66 cannot pass through the limit groove 68, so that the activated carbon plate 23 enters the inner cavity of the filter chamber 21 as a whole, and then the sealing sleeve 26 is reinstalled on the outer side of the filter chamber 21 to block the installation opening 22, and the installation is completed.

[0031] Step 2. In the utility model, when asphalt in the device body 1 burns to generate exhaust gas, the exhaust gas is sucked into the purification device 2 through the exhaust pipe 4 by the suction fan for purification. When the exhaust gas flows in the exhaust pipe 4, since the exhaust pipe 4 is located in the inner cavity of the cooling bin 3, the exhaust pipe 4 is cooled by the coolant contained in the cooling bin 3, so that the exhaust gas temperature inside the exhaust pipe 4 decreases accordingly, and the cooling water contained in the inner cavity of the cooling bin 3 is cooled by the heat dissipation device 5, so that when the exhaust gas enters the inner cavity of the purification device 2 through the exhaust pipe 4, the temperature will decrease.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. The utility model is not limited by the above embodiments.
