Problems solved by technology

However, in the oil fume purification devices currently on the market, the rotor outer rotor motor of the centrifugal fan usually adopts a traditional inner rotor outer rotor motor. This type of traditional rotor outer rotor motor has a large volume, which makes the overall volume of the centrifugal fan larger. As a result, the centrifugal fan is easy to block the air duct, making the air flow in the air duct not smooth, resulting in a small air volume of the centrifugal fan

Abstract

The invention discloses a centrifugal fan and an oil fume purification device. The centrifugal fan comprises a volute, a motor support, an impeller and an outer rotor motor, wherein air inlets are formed in the two opposite sides of the volute; the impeller is arranged in the volute and comprises an installation disc and a plurality of blades arranged along the circumference of the installation disc; the motor support is installed at one air inlet of the volute; the outer rotor motor comprises a stator and a rotor rotationally arranged on the periphery of the stator; the end face of the statoris fixedly connected with the motor support; and the rotor is fixedly connected with the installation disc. According to the centrifugal fan, the size of the centrifugal fan can be reduced, the centrifugal fan is prevented from blocking an air flue, and then the air volume of the centrifugal fan is increased.

Description

technical field [0001] The invention relates to the technical field of oil fume purification devices, in particular to a centrifugal fan and an oil fume purification device. Background technique [0002] In the related art, a centrifugal fan is usually arranged in the oil fume purification device, so as to use the centrifugal fan to drive an airflow to absorb the oil fume. However, in the oil fume purification devices currently on the market, the rotor outer rotor motor of the centrifugal fan usually adopts a traditional inner rotor outer rotor motor. This type of traditional rotor outer rotor motor has a large volume, which makes the overall volume of the centrifugal fan larger. Therefore, the centrifugal fan is easy to block the air duct, so that the air flow in the air duct is not smooth, resulting in a small air volume of the centrifugal fan. Contents of the invention [0003] The main purpose of the present invention is to provide a centrifugal fan, which aims at red...
