[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0023] Please refer to the appendix. Figures 1-4 The present invention provides a low-noise exhaust gas treatment device, including a base 1 and a fan 2. An exhaust gas inlet hose 3 is fixedly connected to the input end of the fan 2 and is connected to an exhaust gas source pipeline. An exhaust gas delivery hose 4 is fixedly connected to the output end of the fan 2. The fan 2 is installed at one end of the top of the base 1 through a noise reduction component. A dual-channel exhaust gas treatment component is fixedly installed at the other end of the top of the base 1 and is connected to the exhaust gas delivery hose 4.
[0024] The noise reduction assembly includes a support plate 5, a noise reduction box 6 fixed to the top of the support plate 5, a fan 2 fixed to the bottom of the support plate 5 and located inside the noise reduction box 6, sound insulation cotton 7 fixed to the inner wall of the noise reduction box 6, a first connecting pipe 8 fixedly connected to the input end of the fan 2, the end of the first connecting pipe 8 passing through the sound insulation cotton 7 and the side end of the noise reduction box 6, the end of the first connecting pipe 8 fixedly connected to the exhaust gas inlet hose 3, a second connecting pipe 9 fixedly connected to the output end of the fan 2, the end of the second connecting pipe 9 passing through the sound insulation cotton 7 and the side end of the noise reduction box 6, the end of the second connecting pipe 9 fixedly connected to the exhaust gas delivery hose 4. Specifically, when the fan 2 is running, it can deliver exhaust gas through the exhaust gas inlet hose 3, the first connecting pipe 8, the second connecting pipe 9 and the exhaust gas delivery hose 4, and under the action of the noise reduction box 6 and the sound insulation cotton 7, it can effectively reduce the noise of the running fan 2.
[0025] The noise reduction assembly also includes several buffer seats 10, the bottom of which is fixed to the top of the base 1. Each buffer seat 10 has a limiting hole 11 at the center of its top, and a limiting guide rod 12 is vertically inserted through the limiting hole 11. The top of the limiting guide rod 12 is fixed to the bottom of the support plate 5. A sliding block 13 is fixed to the bottom of the limiting guide rod 12. The sliding block 13 is slidably connected to the inner surface of the buffer seat 10. A buffer spring 14 is fixed to the bottom of the sliding block 13. The bottom of the buffer spring 14 is fixed to the top of the base 1. Several dampers 15 are also fixed to the top of the base 1. The top of the piston rod of each damper 15 is fixed to the bottom of the support plate 5. Specifically, when the fan 2 vibrates during operation, the support plate 5 can shake, which causes the limiting guide rod 12 to drive the sliding block 13 to move up and down, causing the buffer spring 14 to undergo elastic deformation and generate buffering force. Combined with the energy absorption effect of the damper 15, the vibration force of the fan 2 during operation can be effectively damped and buffered.
[0026] In summary, this waste gas treatment equipment can effectively buffer the vibration and provide sound insulation for the operating fan 2, making the equipment quieter to use and reducing noise pollution.
[0027] The dual-channel exhaust gas treatment assembly includes an exhaust gas inlet pipe 16. One end of the exhaust gas inlet pipe 16 is fixedly connected to the end of the exhaust gas delivery hose 4, and the other end of the exhaust gas inlet pipe 16 is fixedly connected to a first tee pipe 17. First connecting bends 18 are symmetrically fixedly connected to both ends of the first tee pipe 17. Third connecting pipes 19 are fixedly connected to the ends of the first connecting bends 18. Inlet valves 20 are fixedly installed on the bodies of the third connecting pipes 19. An exhaust gas filter section 21 is fixedly connected to the end of each third connecting pipe 19 away from the first connecting bends 18. It should be noted that the exhaust gas filter section 21 is configured as a filter box or filter tank with a built-in activated carbon filter element and other exhaust gas filtration structures to achieve the function of treating exhaust gas. This is conventional technology in the field and well-known to those skilled in the art, and will not be described in detail further. The exhaust gas filter section 21 is fixedly connected to the sides of the filter section 21. A fourth connecting pipe 22 is provided, and each of the fourth connecting pipes 22 is fixed with an exhaust valve 23. A second connecting bend 24 is fixed to the end of the fourth connecting pipe 22 away from the exhaust gas filter section 21. A second three-way pipe 25 is fixedly connected between the two second connecting bends 24. An exhaust pipe 26 is fixedly connected to the end of the second three-way pipe 25. Specifically, when the operator switches the inlet valve 20 on the third connecting pipe 19 and the exhaust valve 23 on the fourth connecting pipe 22 in different channels, the exhaust gas can be controlled to flow through different channels, thereby controlling the exhaust gas to be treated by the exhaust gas treatment section 21 in different channels. That is, the exhaust gas treatment equipment can realize the function of dual-channel switching to treat exhaust gas. Therefore, when replacing the exhaust gas filter section 21, there is no need to stop the operation, which effectively achieves the purpose of continuous treatment of exhaust gas and is beneficial to the efficiency of exhaust gas treatment.
[0028] The usage process of this utility model is as follows: Operators can open the inlet valve 20 on the third connecting pipe 19 and the outlet valve 23 on the fourth connecting pipe 22 in the same channel, and close the inlet valve 20 on the third connecting pipe 19 and the outlet valve 23 on the fourth connecting pipe 22 in another channel. Then, the blower 2 is started. When the blower 2 is running, the exhaust gas can be transported through the exhaust gas inlet hose 3, the first connecting pipe 8, the second connecting pipe 9, and the exhaust gas delivery hose 4. Furthermore, with the help of the noise reduction box 6 and the sound insulation cotton 7, the exhaust gas can be effectively reduced... The operating fan 2 is soundproofed, and when the fan 2 vibrates during operation, the support plate 5 can shake, which causes the limit guide rod 12 to drive the sliding block 13 to move up and down, causing the buffer spring 14 to undergo elastic deformation and generate buffering force. Combined with the energy absorption effect of the damper 15, the vibration force of the fan 2 during operation can be effectively damped and buffered. Therefore, the exhaust gas treatment equipment can effectively buffer the vibration of the operating fan 2 and provide sound insulation, making the exhaust gas treatment equipment quieter to use and reducing noise pollution.
[0029] When the fan 2 is running, the exhaust gas can enter the open channel through the exhaust gas delivery hose 4, exhaust gas inlet pipe 16, and first tee pipe 17 into the first connecting bend pipe 18, third connecting pipe 19, and exhaust gas filter section 21 for treatment. The treated exhaust gas then enters the second tee pipe 25 through the fourth connecting pipe 22 and second connecting bend pipe 24 in the open channel, and is finally discharged through the exhaust pipe 26. When the exhaust gas filter section 21 in the open channel needs to be replaced due to blockage or other reasons after long-term use, there is no need to stop the machine. The operator can open the inlet valve 20 on the third connecting pipe 19 and the outlet valve on the fourth connecting pipe 22 in another channel. The air valve 23 is opened, and the air inlet valve 20 on the third connecting pipe 19 and the air outlet valve 23 on the fourth connecting pipe 22 in the channel are closed, so that the exhaust gas continues to be treated by the exhaust gas treatment section 21 in another channel. Then, the exhaust gas treatment section 21 in the channel that needs to be replaced can be replaced for the next switch. When the exhaust gas treatment section 21 in the other channel needs to be replaced, the above operation steps can be repeated, so that the exhaust gas treatment equipment can realize the function of dual-channel switching to treat exhaust gas. Therefore, when replacing the exhaust gas filter section 21, there is no need to stop the machine, which effectively achieves the purpose of continuous treatment of exhaust gas and is beneficial to the efficiency of exhaust gas treatment.
