[0021] Beneficial effects of the present invention:

[0022] The present invention provides a workshop exhaust high-pressure fan system. Through the provided silencer component, the exhaust gas will first contact the filter screen after entering the dust suppression pipe. The filter screen can achieve preliminary filtration of the exhaust gas, and then the exhaust gas is sucked in from one end of the second tube body. When the sucked exhaust gas flows into the middle section of the second tube body, most of the exhaust gas can move straight to the other end of the second tube body, and the noise sound waves generated in the silencer hole when the exhaust gas flows will be trapped between the two groups of baffles. Because the sound wave is a vibration, when this vibration hits the baffle, the baffle will rebound the sound wave back and forth, thereby gradually weakening the ability of the sound wave and playing a good noise reduction role, avoiding noise pollution to the surrounding environment when the high-pressure fan system is started, and when the sound wave collides with the baffle, the silencer groove opened on its outer wall can cause the sound wave to undergo secondary refracting, thereby further reducing the energy of the sound wave.

[0023] The present invention provides a workshop exhaust high-pressure blower system, which has a first baffle, a second baffle and a spoiler. When the exhaust gas is discharged from the other end of the second tube body, it will flow through the air flow channel formed by the first baffle, the second baffle and the dust suppression pipe. At the same time, the air flow channel is S-shaped, and multiple inflection points will appear in the process of exhaust gas circulation. The first baffle or the second baffle at the inflection point can effectively block and isolate impurities in the exhaust gas, thereby achieving the effect of secondary dust reduction. Subsequently, the exhaust gas passing through the air flow channel will flow into one end of the third tube body and out of the other end. When the exhaust gas When flowing out from the other end of the third tube body, it will contact the spoiler, and at the same time, the exhaust gas is blocked by the spoiler and can flow along its outer wall, and the cross-section of the spoiler is wavy, so when the exhaust gas flows along its outer wall, it will pass through the crests and troughs on the spoiler, and the impurities in the exhaust gas can be effectively blocked by the crests and troughs on the spoiler, thereby achieving a three-time dust reduction effect, and the wavy spoiler can make the sound waves generated when the exhaust gas flows be refracted multiple times on its outer wall, thereby effectively consuming the energy in the sound waves and playing a certain noise reduction role.

[0024] The present invention provides a workshop exhaust high-pressure fan system. During the process of exhaust gas extraction, the exhaust gas will impact the blades, thereby causing the blades to rotate. During the rotation of the blades, the second rotating column can be driven to rotate. The rotation of the second rotating column can drive the cleaning roller and the first gear ring to rotate together. During the rotation of the cleaning roller, the surface of the filter screen can be wiped and cleaned to avoid clogging of the filter screen during long-term operation. When the first gear ring rotates, the first gear plate can be driven to rotate together. The first rotating column can be driven to rotate through the first gear plate. When the first rotating column rotates, the second gear plate fixed at the other end thereof will also rotate. The second gear plate can drive the second gear ring to rotate. When the second gear ring rotates, the annular plate and the sound-absorbing cotton can be driven to make a circular motion, thereby effectively absorbing and reducing the noise inside the silencer cavity, further reducing the noise when the entire fan system is started, and the three groups of sound-absorbing cotton are staggered. Therefore, three groups of circular noise reduction circles can be formed during its rotation, effectively expanding the noise reduction area of ​​the sound-absorbing cotton.

At the same time, the air flow channel is S-shaped, and multiple inflection points will appear during the flow of the exhaust gas. The first baffle 35 or the second baffle 36 at the inflection point can effectively block and isolate the impurities in the exhaust gas, thereby achieving the effect of secondary dust reduction. Subsequently, the exhaust gas passing through the air flow channel will flow into from one end of the third tube body 27 and out from the other end.
