[0016] The beneficial effects of the present invention are as follows:

[0017] 1. Existing silencing equipment reduces noise by setting a sound-absorbing material barrier layer on the inner wall of the pipe. However, dust and debris in the airflow will adhere to the sound-absorbing barrier layer. Over time, the accumulated dust will cause the noise reduction effect to decrease. The present invention sets a filtering mechanism to reduce the contact between dust in the airflow and the silencing layer, reduce the adhesion of dust on the silencing layer, and thus extend the service life of the silencing layer. At the same time, it can self-clean the dust accumulated inside, reduce the frequency of disassembly and maintenance of the equipment, and maintain the long-term use of the equipment.

[0018] 2. Since the surface of the sound-absorbing material has many pores, dust is easily attached and difficult to clean. The present invention provides a dust cleaning mechanism to knock on the surface of the sound-absorbing layer to make the dust on the surface of the sound-absorbing layer fall off automatically, and then make the wiping component contact with the surface of the sound-absorbing layer to sweep the dust on the surface into the inside of the collecting bucket. The sound-absorbing layer is cleaned regularly to maintain the sound-absorbing effect of the sound-absorbing layer, avoid excessive dust accumulation that requires the silencer pipe to be disassembled for cleaning, and increase the intensity of cleaning work.

[0019] 3. The processing effect of high-frequency sound waves after entering the silencer is not sufficient to achieve the noise reduction effect. The present invention sets a vibration component. When the sound wave is large, the wind resistance plate rotates and opens, increasing the contact area between the inner wall of the silencer and the sound wave, so that the sound wave is subjected to multiple reflections and then absorbed by the sound-absorbing layer, thereby achieving the purpose of deep noise reduction. When the airflow is large, the wind resistance plate captures and absorbs dust in the air for a second time, reducing the contact between dust and the sound-absorbing layer and maintaining the sound absorption effect of the sound-absorbing layer.

[0020] 4. The dust in the air needs to be disassembled for cleaning after being filtered, which is difficult to disassemble and clean, and increases the workload of the staff. The present invention arranges a buffer component to keep the dust content of the airflow entering the silencer pipe low, reduce the contact area between the silencer layer and the dust, thereby maintaining the sound absorption effect of the silencer layer, and self-cleaning the collected dust, thereby reducing the maintenance frequency of the staff and extending the service life of the equipment.

[0039] During operation, the air inlet pipe 1 is connected to the ventilation system of the workshop, and the sound waves enter the silencer pipe 201, and are absorbed by the partition 601 and the silencer layer. When the silencer work is performed, the dust in the air flow also enters the silencer pipe 201, and the dust enters the silencer pipe 201 after being filtered by the filtering mechanism 6, thereby reducing the dust accumulation inside the silencer pipe 201. After long-term use, a lot of dust will remain on the inner wall of the silencer layer, which will affect the silencer effect. At this time, the cleaning mechanism 5 is turned on to clean the dust on the inner wall of the silencer layer into the collecting bucket 7, and then the staff will clean out the dust collecting bucket 7.

[0041] The filtering mechanism 6 includes a partition 601, two of which are arranged on the inner wall of the silencer 201, and irregularly shaped holes are opened on the surface of the partition 601. The outer wall of the partition 601 is fixedly connected to the inner wall of the main mechanism 2, and springs 602 are evenly arranged on the side of the partition 601 close to the air intake pipe 1. The end of the spring 602 away from the partition 601 is fixedly connected to a buffer plate 603, and an arc hole is opened on the surface of the buffer plate 603.

[0042] During use, the gas enters the interior of the silencer tube 201 through the buffer component 604. The buffer component 604 filters the gas and collects dust inside the buffer component 604. The sound waves are reflected after contacting the buffer plate 603 and the partition plate 601, and then absorbed by the silencer layer. After being used for a period of time, the dust attached to the inner wall of the buffer component 604 gradually increases, which is easy to block the passage of airflow and also has a certain impact on the transmission of sound waves. At this time, the buffer component 604 cleans the dust inside it into the duct 605, and the duct 605 guides the dust into the collection bucket 7. The filtering mechanism 6 is set at the air inlet, which can reduce the contact between the dust in the airflow and the silencer layer, reduce the dust attached to the silencer layer, and thus extend the service life of the silencer layer. At the same time, it can self-clean the dust accumulated inside, reduce the frequency of equipment disassembly and maintenance, and maintain the long-term use of the equipment.

[0043] The cleaning mechanism 5 also includes a sleeve plate 503, the outer wall of the sleeve plate 503 is rotatably connected to the outer wall of the vibration component 502, the inner wall of the sleeve plate 503 is slidably connected to the outer wall of the screw 501, and telescopic rods 504 are evenly arranged on the side of the sleeve plate 503 away from the vibration component 502. The outer wall of the telescopic rod 504 is rotatably connected to the outer wall of the sleeve plate 503, and the end of the telescopic rod 504 away from the sleeve plate 503 is rotatably connected to a mounting frame 505, and the outer wall of the mounting frame 505 is fixedly connected to the inner wall of the silencer pipe 201.

[0044] After being used for a period of time, a layer of dust will still be attached to the surface of the sound-absorbing layer. At this time, the mounting frame 505 drives the telescopic rod 504 to move the vibration component 502 along the screw 501. The vibration component 502 rotates and moves along the screw 501, and at the same time knocks on the surface of the sound-absorbing layer to make the dust on the surface of the sound-absorbing layer fall off automatically. Then, the wiping component 506 contacts the surface of the sound-absorbing layer and sweeps the dust on the surface into the inside of the collecting bucket 7. The sound-absorbing layer is cleaned regularly to maintain the sound-absorbing effect of the sound-absorbing layer and to avoid excessive dust accumulation that requires the sound-absorbing pipe 201 to be disassembled for cleaning, thereby increasing the intensity of cleaning work.

[0045] Example 2, please refer to Figure 1-Figure 9 The present invention provides a technical solution: on the basis of embodiment 1, the vibration component 502 includes a moving sleeve 5021, the inner wall of the moving sleeve 5021 is threadedly connected to the outer wall of the screw rod 501, the outer wall of the moving sleeve 5021 is slidably connected to the outer wall of the sleeve plate 503, the outer wall of the moving sleeve 5021 is evenly provided with support plates 5022, the outer wall of the support plate 5022 is fixedly connected to the outer wall of the moving sleeve 5021, the bottom of the support plate 5022 is rotatably connected to a wind resistance plate 5023, the wind resistance plate 5023 is a lightweight multi-layer mesh material that can absorb dust, the top of the support plate 5022 is rotatably connected to a rotating rod 5024, and the end of the rotating rod 5024 close to the moving sleeve 5021 is fixedly connected to a counterweight ball 5025.

[0046] When the sound-absorbing layer needs to be cleaned, the telescopic rod 504 drives the movable sleeve 5021 to move along the screw rod 501, and the movable sleeve 5021 makes a spiral motion. At the same time, the rotating rod 5024 drives the counterweight block to rotate 90 degrees to knock the sound-absorbing layer, so that the dust on the surface of the sound-absorbing layer falls off, and the sound-absorbing layer is vibrated to reduce the viscosity of the dust adhering to the sound-absorbing layer, making the dust easier to clean. When the sound wave is large, the wind resistance plate 5023 rotates and opens to increase the contact area between the inner wall of the sound-absorbing pipe 201 and the sound wave, so that the sound wave is subjected to multiple reflections and then absorbed by the sound-absorbing layer to achieve the purpose of deep noise reduction. When the airflow is large, the wind resistance plate 5023 captures and absorbs the dust in the air for a second time to reduce the contact between the dust and the sound-absorbing layer and maintain the sound absorption effect of the sound-absorbing layer.

[0048] When the vibration component 502 hits the sound-absorbing layer, the moving circle 5061 drives the cleaning teeth 5064 to contact the surface of the sound-absorbing layer, so that the dust is cleaned up by the cleaning teeth 5064. After cleaning for a period of time, some fibrous debris and dust of the sound-absorbing material may be attached to the surface of the cleaning teeth 5064. At this time, the electric push rod 5062 extends outward, driving the cleaning rod to remove the debris attached to the surface of the cleaning teeth 5064, so that the debris is concentrated in the collecting bucket 7. The internal dust can be cleaned without disassembling the silencer pipe 201, thereby maintaining the sound absorption effect of the sound-absorbing layer.

The telescopic column 6041 can adjust the length of the filter bag 6042 according to the size of the airflow. When the airflow is small, the telescopic column 6041 extends to squeeze the filter bag 6042. When the airflow is large or dust accumulates for a period of time, the telescopic column 6041 drives the filter bag 6042 to stretch, so that the part not attached to the dust continues to filter the airflow. After filtering for a period of time, the telescopic column 6041 stretches back and forth to separate the dust inside the filter bag 6042 from the filter bag 6042. 42 inner wall, accumulated at the bottom of the filter bag 6042, at this time, the driving plate 6046 drives the spiral pressing plate to rotate, and the spiral blade 6047 rotates to transport the dust at the bottom of the filter bag 6042 to the connecting pipe 6048, and enters the duct 605 through the connecting pipe 6048, and enters the collecting bucket 7 from the duct 605 under the blowing of the air flow and the action of gravity, so as to keep the dust content of the air flow entering the silencer pipe 201 less, reduce the contact area between the silencer layer and the dust, thereby maintaining the sound absorption effect of the silencer layer, and self-cleaning the collected dust, reduce the maintenance frequency of the staff, and extend the service life of the equipment.

[0051] The specific workflow is as follows:

[0052] The gas enters the interior of the muffler pipe 201 through the buffer component 604, and the buffer component 604 filters the gas, so that the dust is collected inside the buffer component 604. The sound waves are reflected after contacting the buffer plate 603 and the partition plate 601, and then absorbed by the muffler layer. After being used for a period of time, the dust attached to the inner wall of the buffer component 604 gradually increases, which is easy to block the passage of airflow and also has a certain impact on the transmission of sound waves.

[0053] After being used for a period of time, a layer of dust will still adhere to the surface of the sound-absorbing layer. At this time, the mounting frame 505 drives the telescopic rod 504 to move the vibration component 502 along the screw 501. The vibration component 502 rotates and moves along the screw 501, and at the same time knocks on the surface of the sound-absorbing layer to make the dust on the surface of the sound-absorbing layer fall off automatically.
