[0002] A rectangular array silencer is a device used to reduce the spread of noise, usually consisting of multiple rectangular-shaped silencer units. These silencer units are usually made of sound-absorbing materials, such as sound-absorbing cotton or foam plastics, which are used to absorb noise and reduce its spread. Rectangular array silencers can effectively reduce noise levels, and are particularly suitable for noise sources that require large area coverage. Rectangular array silencers are often used in industrial equipment, power plants, air-conditioning systems and other places where noise reduction is required. They can be custom designed and installed as needed to ensure the best noise control effect. When selecting and installing rectangular array silencers, factors such as the type, frequency and intensity of the noise source, as well as the noise level that needs to be reduced and space limitations need to be considered. Existing devices still have some defects; for example;

[0003] For example, a rectangular array silencer with announcement number CN212484933U, when using the technology, the silencer includes a main silencer unit and a rectangular shell, the main silencer unit is located in the shell and fixedly connected to the shell, the main silencer unit includes a plurality of sub-silencer units, the plurality of sub-silencer units are arranged in an array in the shell, and the adjacent sub-silencer units are fixedly connected. The rectangular array silencer increases the area of ​​the silencer channel and improves the silencer effect; the fixing method between the main silencer unit and the shell, and between the sub-silencer units is more flexible and reliable, and compared with the existing silencers, the silencer unit is more convenient to transport, install on site, maintain later, and disassemble;

[0004] The above device has some problems. The device is cumbersome to use and has poor silencing effect. Dust may enter the interior during use, resulting in poor silencing effect due to excessive dust inside.

[0005] Therefore, we propose a rectangular array muffler to solve the above problems. Utility Model Content

[0015] 1. The device is provided with a silencer structure. When in use, the sound enters from the left side of the body, passes through the through hole in the partition inside the left side, and then enters the body. When the sound reaches the threaded rod at the front end of the fixed rod, due to the increase in the entry speed, a vortex motion will be generated inside. This motion will produce the interaction between the pressure wave and the forced vortex, so that the energy of the sound wave is attenuated. At the same time, the sound can be absorbed by the sound-absorbing cotton inside the body. At the same time, the filter on the surface of the sound-absorbing cotton can prevent excessive dust from causing poor sound absorption. At this time, the sound airflow enters the silencer inner core through the second through hole, and at the same time, the sound airflow at the upper and lower ends enters the silencer outer core through the third through hole, so that the sound path is extended, and the sound is gradually attenuated to achieve the purpose of silencer.

[0024] When in use, sound enters from the left side of the body 1, passes through the first through hole 3 in the partition 2 inside the left side, and then enters the body 1. When the sound reaches the threaded rod 5 at the front end of the fixed rod 4, due to the increase in the entry speed, a vortex motion will be generated inside. This motion will produce the interaction between the pressure wave and the forced vortex, so that the energy of the sound wave is attenuated. At the same time, the sound can be absorbed by the sound-absorbing cotton 13 inside the body 1. At the same time, the filter 6 on the surface of the sound-absorbing cotton 13 can prevent excessive dust from causing poor sound absorption. At this time, the sound airflow enters the silencer inner core 9 through the second through hole 10, and at the same time, the sound airflow at the upper and lower ends enters the silencer outer core 11 through the third through hole 12, so that the sound path is extended, and the sound is gradually attenuated to achieve the purpose of silencing;

At the same time, due to the setting of the silencer outer core 11, it can prevent the silencer from being unable to be performed due to the blockage of the silencer inner core 9. At the same time, the filter plate 7 on the right side of the body 1 can prevent dust from entering and causing the silencer inner core 9 and the silencer outer core 11 to be blocked by dust. When there is too much dust on the surface of the filter plate 7, the filter plate 7 can be pulled out for cleaning by holding the handle above the body 1.

[0027] Working principle: When using the rectangular array silencer, the sound enters from the left side of the body 1, passes through the first through hole 3 in the partition 2 inside the left side, and then enters the inside of the body 1. When the sound reaches the threaded rod 5 at the front end of the fixed rod 4, due to the increase in the entry speed, a vortex motion will be generated inside. This movement will produce the interaction of pressure waves and forced vortices, so that the energy of the sound waves can be attenuated. At the same time, the sound can be absorbed by the sound-absorbing cotton 13 inside the body 1. At the same time, the filter 6 on the surface of the sound-absorbing cotton 13 can prevent excessive dust from causing poor sound absorption. At this time, the sound airflow enters the silencer inner core 9 through the second through hole 10, and at the same time, the sound airflow at the upper and lower ends enters the silencer outer core 11 through the third through hole 12, so that the sound path is extended, and the sound is gradually attenuated to achieve the purpose of silencing. At the same time, when the silencer outer core 11 is in use When there is too much dust inside, the silencer outer core 11 can be unplugged for cleaning. During installation, you only need to insert the silencer outer core 11 into the silencer inner core 9. Since a gasket is provided at the connection, the connection can be more stable. At the same time, due to the setting of the silencer outer core 11, it can prevent the silencer from being unable to be performed due to the blockage of the silencer inner core 9. At the same time, the filter plate 7 on the right side of the body 1 can prevent dust from entering and causing the silencer inner core 9 and the silencer outer core 11 to be blocked by dust. When there is too much dust on the surface of the filter plate 7, you can hold the handle above the body 1 to pull out the filter plate 7 for cleaning.
