Abstract

The invention provides a pulse aeration pipe dredging tool which comprises a hard pipeline, a hose, a medium supply device and nozzles, wherein the medium supply device is communicated with the hard pipeline through the hose, the nozzles are arranged on the outer wall of the hard pipeline in a protruding mode and correspond to the aeration holes of the pulse aeration pipe, when the nozzles are inserted into the aeration holes, the nozzles are in sealing contact with each other, after the nozzles are inserted into the aeration holes, the medium supply device is controlled to guide the medium into the hard pipeline through the hose, and the medium in the hard pipeline is sprayed out from the nozzles to dredge the pulse aeration pipe. According to the invention, under the condition that the cover plate is not arranged on the aeration hole, the cleaning of the pulse aeration pipe can be realized without lifting the membrane tank from the sewage pool, so that not only is a great amount of workload for disassembling the membrane tank saved, but also the membrane tank is not required to be stopped to work, and the continuous operation of a sewage plant is realized.
