This utility model discloses a self-aeration sludge discharge pipe device and a sludge discharge pipeline structure. The self-aeration sludge discharge pipe device includes a sludge discharge pipe, within which an anti-clogging air pipe is installed for aeration. The anti-clogging air pipe has aeration holes on its wall, and microporous aeration membranes are installed at the aeration holes. The anti-clogging air pipe is connected to an external air source via an air supply pipeline. The air supply pipeline includes an automatic valve for controlling the opening and closing of the air supply pipeline. The automatic valve and the air source are connected to a control device that controls the opening and closing of the automatic valve and the start and stop of the air source. This utility model integrates an anti-clogging air pipe within the sludge discharge pipe and connects it to an air source via an air supply pipeline, thereby allowing for staged air flushing of the sludge discharge pipe, effectively reducing the probability of clogging and avoiding the need for unclogging after blockage.
