Description

Technical Field

[0001] The utility model relates to the technical field of dust removal silencers, in particular to a silencer with dust removal effect. Background Art

[0002] The silencer is an auxiliary device used to prevent sound from propagating in the air and only allow airflow to pass through. It is an important component for eliminating aerodynamic noise. The dust collector fan silencer is a noise reduction device installed in the airflow channel of the fan or in the intake and exhaust systems. Its working principle is that the silencer is provided with porous sound-absorbing materials. When the sound waves enter the silencer, part of the sound energy is converted into heat energy consumption by friction in the pores of the porous material, which ultimately plays a role in weakening the sound waves. The fan in the dust removal equipment system runs at a high speed and generates a lot of noise, which is easy to cause noise pollution. It is necessary to install a silencer between the fan and the exhaust chimney. The air in the existing dust removal equipment system is prone to carry fine dust, which is easily absorbed by the silencer cotton in the silencer, resulting in a decrease in the silencer effect. The long-term accumulation of dust on the silencer cotton will cause the silencer to lose its silencer effect.

[0003] Therefore, a filter is usually used to clean the dust that enters the silencer cotton to prevent the dust from accumulating on the silencer cotton for a long time. However, the filter is inconvenient to replace during long-term use, which can easily cause the filter to lose its filtering function and affect the use effect of the silencer. Utility Model Content

When there is a lot of dust in the air blown out by the fan, the limit assembly structure can be controlled to work, and the slider 18 can move. The slider 18 adjusts the position of the limit baffle 9, which will increase the number of assembled filter plates 14 at the rear end of the fixed filter plate 15, ensure a good filtering effect, and can also reduce the replacement of the fixed filter plate 15 and the assembled filter plate 14. The number of times improves the work efficiency. When the fixed filter plate 15 and the assembled filter plate 14 are placed in the filter box 3, the buffer and tight structure work, the sliding column 12 slides along the inner wall of the filter box 3, and the block 13 pushes the fixed filter plate 15 and the assembled filter plate 14 to one end of the connecting pipe 5, ensuring that the fixed filter plate 15 and the assembled filter plate 14 completely block the pipe opening of the connecting pipe 5, ensuring that the fixed filter plate 15 and the assembled filter plate 14 can effectively filter the dust mixed in the gas in the connecting pipe 5, and then the air enters the muffler 1 through the air inlet 4, and is discharged from the air outlet 2 after passing through the muffler 1.

[0024] The limiting assembly structure also includes a connecting block 16 fixedly connected to the fixed filter plate 15, one end of the connecting block 16 is rotatably connected to a worm 10, the worm 10 is meshed with a worm wheel 20, the worm wheel 20 is fixedly connected to a screw 17 rotatably connected to the connecting block 16, and the inner wall of the slider 18 is fixedly connected to a screw barrel 19 threadedly connected to the screw 17.
