Working principle and using flow:
the novel intelligent noise reduction muffler is connected to a pipeline requiring ventilation and noise elimination, and the noise detector 2 and the coil 4410 are powered on.
When the noise air flow passes through the plurality of groups of fan-shaped silencing sheets 32, friction is generated between the noise air flow and the fan-shaped silencing sheets 32, so that the energy of the noise is converted into heat energy, the sound of the noise is reduced, when the noise is absorbed and passes through the rectangular silencing sheets 42, friction is generated between the noise air flow and the rectangular silencing sheets 42, the energy of the noise is converted into heat energy, and the sound of the noise is further reduced.
When the noise detector 2 detects a change in noise, if the detected noise is increased, the noise detector 2 reduces the current flowing through the coils 4410 on both sides of the control spring 448, so that the attractive force generated between the energized coils 4410 is reduced, the resistance force received by the spring 448 is reduced, the distance between the two adjusting plates 447 is increased, that is, the inner cavity shell 442 moves toward the center of the rectangular shell 41, the space between the outer cavity shell 441 and the inner cavity shell 442 is increased, the resonance frequency is changed, so that the energy of the noise is more likely to resonate with the air between the outer cavity shell 441 and the inner cavity shell 442, and the capability of absorbing high noise is enhanced; when the detection noise is reduced, the noise detector 2 increases the current supplied to the coils 4410 on both sides of the control spring 448, thereby increasing the attractive force generated between the coils 4410, increasing the resistance to which the spring 448 is subjected, thereby reducing the distance between the two adjusting plates 447, that is, moving the inner chamber case 442 toward the outer chamber case 441, reducing the space between the outer chamber case 441 and the inner chamber case 442, and changing the resonance frequency, thereby making the energy of the noise more likely to resonate with the air between the outer chamber case 441 and the inner chamber case 442, and enhancing the capability of absorbing high and low noise.
When noise passes through the rectangular openings 443 of the outer and inner housings 441 and 442, energy of the noise enters the space between the outer and inner housings 441 and 442 from the rectangular openings 443, so that air of the rectangular openings 443 moves back to compress air in the space between the outer and inner housings 441 and 442 to form an air spring, thereby resonating, and the resonating air collides with the sound insulation plate 444 and the sound insulation holes 445 of the sound insulation plate 444, so that more noise energy is converted into heat energy, so that the energy of the noise is consumed more, and the noise is reduced.
In the process of absorbing noise by the rectangular silencing sheets 42, impurities in noise airflow can block holes of the rectangular silencing sheets 42, so that silencing effect is weakened, at the moment, the motor 5 is electrified to drive the rotating shaft 61 to rotate, so that the U-shaped ropes 63 are tightened on the rotating shaft 61, the U-shaped ropes 63 are tightened to drive the connecting blocks 66 at two ends to move along the sliding grooves 69, brushes 68 on the connecting blocks 66 rotate to clean the rectangular silencing sheets 42, when the connecting blocks 66 move to the forefront, the motor 5 is powered off, the airflow flowing through the rectangular shell 41 drives the brushes 68 to move to the rearmost end, and the rectangular silencing sheets 42 can be cleaned again in a rotating manner; by cycling in this way, the rectangular muffler plate 42 is cleaned.
