The utility model belongs to the technical field of batteries, and particularly provides a rotating wheel self-cleaning
system which comprises a rotating wheel body, the rotating wheel body comprises a box body, a
molecular sieve rotating wheel and an outer exhaust fan, the
molecular sieve rotating wheel and the outer exhaust fan are installed in the box body, a
fresh air inlet is formed in one end of the box body, and an air outlet communicated with a filter box is formed in the other end of the box body. One end of the
molecular sieve rotating wheel is communicated with the
fresh air inlet, the other end of the molecular
sieve rotating wheel is communicated with the air outlet through the external exhaust fan, the rotating wheel body further comprises a pipeline and a Y-shaped filter, the inlet end of the pipeline is communicated with the air outlet of the external exhaust fan, the outlet end of the pipeline is communicated with the molecular
sieve rotating wheel, and the pipeline penetrates through the molecular
sieve rotating wheel and is provided with holes; the opening is located in the molecular sieve rotating wheel, the Y-shaped filter is installed on the pipeline and located on the side close to the outlet end, and the air speed in the pipeline is larger than that in the molecular sieve rotating wheel. Dust in the molecular sieve rotating wheel can be sucked into the pipeline through negative pressure and is filtered, and the replacement frequency of the filter box is effectively reduced.
