[0002] The blower is composed of a motor, a fan chassis and other equipment. Air is drawn in through one side of the blower, and the motor drives the impeller to rotate at high speed through the shaft. The airflow enters the high-speed rotating impeller axially from the inlet and becomes radial flow and is accelerated. Then it enters the diffusion chamber, changes the flow direction and slows down. This deceleration effect converts the kinetic energy in the high-speed rotating airflow into pressure energy or potential energy, so that the fan outlet maintains a stable pressure and discharges the air from the other side of the blower.
[0003] When some high-temperature furnaces, ironmaking furnaces and other equipment are running, smoke and dust will be generated, so the smoke and dust need to be discharged in time, and a blower device is needed to discharge the smoke and dust in a directional manner. In actual use, impurities in the smoke and dust will be sucked into the blower, which will damage the wind wheel inside the blower and is inconvenient to clean. Therefore, we propose a smoke exhaust blower device to improve the above problems. Utility Model Content

The non-woven fabric layer 21 between the sound-absorbing cotton layer 20 and the sound-absorbing hole layer 22 can filter dust while silencing, prevent dust from entering the sound-absorbing cotton layer 20, and reduce the sound-absorbing effect of the sound-absorbing cotton layer 20. Finally, when the rotating motor 1 drives the bearing box 8 and the fan case 13 to run through the connecting shaft seat 3, vibration is generated, which will be transmitted to the anti-slip rubber block 23 at the bottom of the contact base 9 through the supporting fixed seat 2, and the buffer air bag 25 inside the anti-slip rubber block 23 increases the buffering property of the anti-slip rubber block 23.
