[0038] As shown in Figures 1-8 The dust removal mechanism of the present application comprises two main plates 1, an acoustic absorption and noise reduction module 2 is fixedly installed between the two main plates 1, a semi-enclosed groove 3 is formed on the bottom side in the acoustic absorption and noise reduction module 2; a dust suction port 4 is formed on the top side in the semi-enclosed groove 3, an exhaust duct 5 is connected to the upper end of the dust suction port 4, the exhaust duct 5 is fixedly installed in the acoustic absorption and noise reduction module 2, and the outer end of the exhaust duct 5 extends out of the main plate 1; two positioning edges 6 are fixedly installed between the two main plates 1, a dust removal module 7 is installed between the two positioning edges 6, and the positioning edges 6 and the dust removal module 7 are both arranged in the semi-enclosed groove 3;
[0039] The principle is that the half-enclosing groove 3 of the sound absorption and noise reduction module 2 covers the dust removal module 7, so that the noise generated by the dust removal module 7 during operation is blocked to a certain extent; the sound absorption and noise reduction material 8 in the sound absorption and noise reduction module 2 realizes sound absorption and noise reduction, and effectively reduces the noise generated by the dust removal equipment during operation to below 80 decibels; during dust collection, the dust removal module 7 blows high-pressure gas onto the product, and then allows the gas to enter the exhaust pipe 5 through the gap between the dust removal module 7 and the half-enclosing groove 3 for exhaust, so that the high-pressure gas flows in the half-enclosing groove 3, and the structure of the sound absorption and noise reduction module 2 can reduce the noise generated by the high-pressure gas during flow.
[0040] Further, the sound absorption plates 14 are fixedly installed on the two sides of the dust removal module 7, and the sound absorption and noise reduction material 15 is filled and installed between the sound absorption plates 14 and the dust removal module 7; the sound absorption plates 14 and the sound absorption and noise reduction material 15 can be used to absorb the noise generated during gas blowing to a certain extent, and then cooperate with the sound absorption and noise reduction module 2 to realize the effect of double-layer noise reduction.
[0041] During operation, compressed air is sprayed from the rotating gas blowing nozzle of the dust removal module 7, and wind howling sound is generated; the noise can be absorbed by the sound absorption plates 14 and the sound absorption and noise reduction material 15, and then a part of the sound is sucked away; the wind volume blown out of the gas blowing nozzle will hit the product to form an “audio explosion”; the airflow will enter the dust suction port 4 through the gap between the positioning edge 6 and the half-enclosing groove 3, and then be output through the exhaust pipe 5; at this time, the noise can be effectively reduced by the half-enclosing sound absorption and noise reduction module 2, the sound transmission is blocked by multiple media, and the effect of effective sound absorption and noise reduction is realized.
