DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] As Figure 1As shown, the utility model provides a technical scheme: a kind of blast fan pipeline muffler for high dust environment, including muffler 1, air inlet cover 2, first connecting cover 3, second connecting cover 5 and fan 6, wherein, the air inlet and air outlet of muffler 1 are connected between first connecting cover 3 and second connecting cover 5 by connecting flange 4, locking bolt 13 is provided on connecting flange 4, the top of first connecting cover 3 is connected with air inlet cover 2, the bottom of second connecting cover 5 is connected with fan 6.

[0023] As Figure 1 Shown, air inlet cover 2 is equipped with multiple air inlets 7 (air inlet cover 2 is square shape, four sides and top are equipped with air inlet 7), and each air inlet 7 is equipped with angle-adjustable mesh grating plate 8.

[0024] As Figure 2 Shown, the inner wall of muffler 1 is provided with honeycomb-shaped porous sound-absorbing plate 10 (honeycomb structure can make sound wave repeatedly refract transmission in it, so as to realize the purpose of noise reduction) and sound-absorbing cotton 9 from inside to outside.

[0025] As Figure 1 Shown, the outside of muffler 1 is provided with noise measuring instrument 17, and the decibel size in muffler 1 can be monitored by noise measuring instrument 17, when noise is too large, muffler core 14 needs to be removed and cleaned.

[0026] As Figure 1 Shown, the top of muffler 1 is provided with blowing channel 11, and the top of blowing channel 11 is provided with annular compressed air blowing pipe 12 extending to the outside, and annular compressed air blowing pipe 12 is provided with compressed air by external air compressor.

[0027] As Figure 3 Shown, muffler core 14 is arranged in the middle of the inner cavity of muffler 1, and muffler core 14 includes air cap 141 at the top (air cap 141 can introduce exhaust gas into sound-absorbing column core 142) and honeycomb-shaped sound-absorbing column core 142 at the lower part (material is similar to porous sound-absorbing plate 10).

[0028] As Figure 1 Shown, the outside of muffler core 14 is provided with connecting rod 15, and the inside of porous sound-absorbing plate 10 is provided with clamping sleeve 16, connecting rod 15 can be inserted into clamping sleeve 16, under the action of exhaust gas pressure, muffler core 14 can be stably fixed in clamping sleeve 16.

[0029] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0030] During use, the exhaust gas discharged from the grate cooler enters through the air inlets 7 on multiple sides of the air inlet hood 2. The mesh grille 8 inside the air inlet 7 can adsorb the dust in the exhaust gas, thereby reducing the dust content in the exhaust gas.

[0031] The exhaust gas then enters the silencer 1, where it is treated to reduce noise through the sound-absorbing materials inside the silencer 1, such as the silencer core 14, the porous sound-absorbing plate 10, and the sound-absorbing cotton 9. Finally, the exhaust gas is discharged by the fan 6.

[0032] Compressed air can be introduced through the annular compressed air jet pipe 12 and enter the porous sound-absorbing plate 10 through the jet channel 11, thereby blowing out the dust adsorbed in the porous sound-absorbing plate 10 to prevent it from being blocked and to ensure the smooth flow of the sound-absorbing material.

[0033] Regarding the muffler core 14, the muffler 1 can be removed periodically, and then the muffler core 14 can be taken out for cleaning to prevent the muffler core 14 from becoming clogged and affecting the noise reduction performance.

[0034] In summary, this blower duct silencer for high-dust environments effectively absorbs dust from the airflow by incorporating a dust-collecting air inlet hood, making it suitable for such environments. Secondly, the jet-blowing structure effectively blows away dust from inside the silencer, alleviating the problem of the perforated plate becoming clogged. Finally, the silencer's modular design allows for the periodic replacement of the sound-absorbing material, ensuring that the noise reduction effect does not diminish.
