Negative pressure type generator slip ring chamber carbon powder pumping device

The utility model relates to the technical field of carbon powder treatment, and discloses a negative pressure type generator slip ring chamber carbon powder pumping device which is installed on the opposite side of a cleaning face, then a pipeline extends out of a skylight, and then a generator slip ring chamber works after being powered on. The generator slip ring chamber discharges flying carbon powder in the purging carbon brush chamber to the outside of the engine room through the pipeline, so that the effect of eliminating dust pollution caused by purging the carbon powder in the slip ring chamber is achieved, and the good effects of preventing dust from entering respiratory system occupational diseases and protecting the operation environment of fan equipment are achieved; when the axial flow fan stops, the thrust of the interior of the pipeline to the baffle is insufficient through the torsion of the torsion spring, and the torsion of the torsion spring can drive the baffle to quickly block the throug
