Abstract
The utility model relates to the technical field of centrifugal fans, and discloses an anti-dust-deposition centrifugal fan with a self-cleaning impeller, which comprises a support, the top of the support is fixedly connected with a machine shell, the top of the machine shell is fixedly connected with an air outlet pipe, the top of the machine shell is provided with a replacement mechanism, and the outer part of the machine shell is fixedly connected with a motor. The output end of the motor is fixedly connected with an impeller body, the outside of the impeller body is fixedly connected with a plurality of blades, and the outside of the machine shell is fixedly connected with a filter plate. According to the blade cleaning device, through the elastic effect of the spring and the sliding effect of the sliding plate, the blade is rapidly cleaned, meanwhile, after cleaning is completed, the brush can be rapidly taken out to be cleaned and replaced, and the working efficiency is improved; besides, through mutual cooperation of a spring and a filter plate, the problem that the interior of the equipment cannot be rapidly overhauled is solved, meanwhile, external dirt is prevented from entering the interior of the equipment, and the service life of the equipment is prolonged.
