[0026] The input end of the fan 225 is connected to an input pipe 210 , and the input pipe 210 is connected to the exhaust gas source. The output end of the fan 225 is connected to the exhaust gas treatment device body 100 .
[0027] See also Figure 2 and Figure 3 , six noise reduction and sound insulation boards 224 are provided, and the six noise reduction and sound insulation boards 224 form a rectangle. The fan 225 is installed in the rectangle formed by the noise reduction and sound insulation boards 224, and the noise reduction and sound insulation boards 224 are used to prevent noise from spreading outward. The fan mounting member 220 also includes a top connecting plate 223 and a bottom connecting plate 222, and a plurality of bottom connecting plates 222 and a plurality of top connecting plates 223 are provided respectively, and the plurality of bottom connecting plates 222 and the plurality of top connecting plates 223 are fixedly connected to the bottom and the top of the fan 225, respectively, and the bottom of the plurality of bottom connecting plates 222 is fixedly connected to the bottom of the bottom mounting plate 221, and the bottom connecting plate 222 and the top connecting plate 223 are used to transmit the vibration generated by the fan 225 to the noise reduction member 230, so that the noise reduction member 230 performs noise reduction.
[0028] See also Figures 2 to 4 There are two groups of noise reduction components 230, which are respectively arranged at the top and bottom of the fan 225. The noise reduction component 230 also includes a first limit plate 232 and a second limit plate 233. The top of the first limit plate 232 is horizontally limited and slidably connected to the mounting plate 231, and the bottom of the second limit plate 233 is longitudinally limited and slidably connected to the fixing plate 234. The sound absorbing plate 238 is located between the second limit plate 233 and the first limit plate 232. The second limit plate 233 and the first limit plate 232 are upper and lower limited and slidably connected, and the sound absorbing plate 238 further absorbs noise.
[0029] A noise reduction component 230 is installed on the top of the fan 225 through the top connecting plate 223 and the bottom mounting plate 221 respectively. The noise reduction component 230 is fixedly connected to the bottom mounting plate 221 and the top connecting plate 223 through the mounting plates 231 respectively. The fixing plates 234 are fixedly installed to the top and bottom noise reduction and sound insulation plates 224 respectively. The fan 225 is vibrated simultaneously from top to bottom to reduce the transmission of noise.
[0030] The top two ends of the first limit plate 232 and the bottom two sides of the second limit plate 233 are respectively provided with limit sliders in the horizontal and vertical directions, and the limit sliders are all isosceles trapezoidal. The bottom of the mounting plate 231 is provided with a limit slide groove that cooperates with the limit slide above the first limit plate 232, and the surface of the fixed plate 234 is provided with a limit slide groove that cooperates with the limit slide at the bottom of the second limit plate 233.

The first damping spring shock absorber 236 is used to reduce the horizontal shaking of the first limit plate 232 and weaken the transmission of vibration. If longitudinal shaking occurs, the second limit plate 233 will slide longitudinally on the fixed plate 234 and cooperate with the second damping spring shock absorber 237 to reduce the longitudinal movement to reduce the transmission of vibration.

The two hinge blocks 235 are limitedly hinged with the first damping spring damper 236. The first damping spring damper 236 is tilted. If up and down shaking occurs, the first limit plate 232 slides up and down on the second limit plate 233. At the same time, the tilt of the first damping spring damper 236 is convenient for weakening the up and down shaking force, thereby reducing the transmission of vibration. The second damping spring damper 237 is fixedly connected to the two ends of the second limit plate 233, respectively. Extension blocks are set at both ends of the fixed plate 234, and the extension blocks are fixedly connected to the second damping spring damper 237.
[0032] Working principle: when the fan 225 is installed, noise reduction components 230 are respectively installed on the top and bottom of the fan 225. When the fan 225 works on the noise reduction component 230, vibration will be generated. The first limit plate 232 and the second limit plate 233 cooperate with the first damping spring shock absorber 236 and the second damping spring shock absorber 237 to reduce the transmission of vibration. If the fan 225 shakes during operation, the first damping spring shock absorber 236 and the second damping spring shock absorber 237 will weaken the shaking. The shaking of the fan 225 is reduced by cooperating with the sound absorbing panel 238 and the noise reduction and sound insulation panel 224 to reduce the noise emitted by the fan 225.
