The invention relates to the technical field of centrifugal dust removal exhaust fans, and discloses a centrifugal dust removal exhaust fan for industrial environmental protection. The centrifugal dust removal exhaust fan comprises a bearing box, a motor and rotating shafts, wherein the motor is fixedly arranged on one side of the bearing box; the rotating shafts are fixedly arranged at the outputend of the motor; a round hole is formed in the bearing box; the rotating shafts penetrate through the round hole; an annular groove is formed in the inner side wall of the round hole; a gas groove is formed in one side of the annular groove; and a gas outlet hole is formed in the bottom of the gas groove. According to the centrifugal dust removal exhaust fan for industrial environmental protection, an airflow barrier is formed, when impurities enter from the opening, the impurities can be blocked by the barrier, so that lubricating oil on the rotating shafts cannot be doped with the impurities entering from the outside, and the lubricating quality of the lubricating oil is guaranteed; and meanwhile, after no particulate matter enters, the rotation between the rotating shafts is smoother,so that the rotation is more stable, and the service life of the rotating shafts is prolonged.
Description
technical field [0001] The invention relates to the technical field of centrifugal dust removal and exhaust fans, in particular to a centrifugal dust removal and exhaust fan for industrial environmental protection. Background technique [0002] Centrifugal dedusting exhaust fan is a fan that removes particulate impurities in the air. During operation, the air is sucked in from the inlet by the rotation of the impeller, and the air is dedusted after being centrifugally treated inside. In this process, in order to ensure smoother rotation of the impeller, it is necessary to add lubricating oil to the rotating shaft. However, when the air containing particulate impurities enters the fan, the impurities may enter the gap between the rotating shaft and the fan along the gap. In the connecting hole, the lubricating oil is mixed with granular impurities, which affects the lubricating performance of the lubricating oil, causes the rotation of the impeller to be unstable, and affects...
