Submersible anti-wear aeration device

Abstract

The invention provides a submersible anti-wear aeration device, and relates to the technical field of water area aeration. The submersible anti-abrasion aeration device comprises an aeration device, exhaust pipes, an exhaust filtering mechanism, water pumping pipes, a water pumping filtering mechanism and water drainage pipes, wherein the exhaust pipes are evenly and fixedly connected to the position, close to the upper portion of the bottom end, of the aeration device, the exhaust filtering mechanism is fixedly connected to the top ends of the exhaust pipes, the water pumping pipes are evenly and fixedly connected to the positions, close to the outer side of the bottom end, of the aeration device, the other ends of the water pumping pipes are fixedly connected with the water pumping filtering mechanism, the outer side of the aeration device is uniformly and fixedly connected with the water drainage pipes close to the lower portion of the water pumping filtering mechanism at the bottom end, and the water pumping filtering mechanism prevents a plastic bag entering a spiral water guide cylinder from entering the aeration device to influence the normal operation of the aeration device due to overlarge volume, so that the problem that hard particles in air enter the aeration device along with airflow to abrade the fan blades of the aeration device so as to seriously affect the aeration effect of the aeration device is solved.

Description

technical field [0001] The invention relates to the technical field of water area aeration, in particular to a submersible anti-wear aeration device. Background technique [0002] In the water treatment process, the aeration equipment is the key equipment for the biological pretreatment of water and sewage biological treatment. Its function is to take certain technical measures to transfer the oxygen in the air to the liquid in the aeration tank through the aeration device. To supply the oxygen required for the metabolism of aerobic organisms, and at the same time fully and evenly mix the water in the pool to achieve the purpose of biological treatment. [0003] In the process of aerating the water area, the negative pressure generated by the aeration device in windy weather will suck the hard particles carried in the external air into the aeration device, which will cause the wear of the fan blades in the aeration device and reduce the aeration. The service life of the aer...
