Description

Technical Field

[0001] This utility model relates to the field of aeration pipeline technology, and in particular to a lift-type aeration pipeline for sewage treatment. Background Technology

[0002] In wastewater treatment, aeration tanks introduce oxygen into the wastewater through mechanical means or gas injection, ensuring that microorganisms have sufficient oxygen to maintain their aerobic respiration, thereby accelerating the decomposition of organic matter and the removal of pollutants. The airflow generated during aeration also drives water flow, achieving thorough mixing of wastewater and activated sludge, ensuring effective contact between microorganisms and pollutants, and improving treatment efficiency.

[0003] Aeration pipes are usually installed at the bottom of the aeration tank. When maintenance personnel repair the existing aeration pipes, they usually need to drain the sewage in the aeration tank, which is not only time-consuming but also costly. In addition, the sludge that accumulates at the bottom of the tank and the odorous gases and harmful substances emitted will also make the working environment of maintenance personnel harsh. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a lifting aeration pipeline for sewage treatment, whose aeration components can be raised as a whole to the top of the aeration tank, making its maintenance more convenient, safe and hygienic.

[0005] This utility model is achieved using the following technical solution: a lifting aeration pipeline for sewage treatment, comprising an aeration assembly, a frame, support legs, sliding rods, sliding sleeves, sliding columns, sliding column frames, sliding column bases, and a pull rod. Several support legs are symmetrically fixed to the bottom of the frame for support. Two sliding rods are symmetrically welded to the left and right sides of the center of the frame. The sliding sleeves are welded and fixed to the outer ends of the sliding rods and are fitted onto the outer ring of the sliding column, allowing the sliding sleeves to slide vertically up and down along the sliding column. The sliding column frame is welded and fixed to the upper outer side of the sliding column, and the sliding column base is welded and fixed to the bottom end of the sliding column. The sliding column frame is fixed to the side wall of the aeration tank, and the sliding column base is fixed to the bottom end of the aeration tank. The pull rod is fixed above the frame for lifting the frame.

[0006] Furthermore, the aeration assembly includes an air inlet pipe, a main tee, a main pipe, a secondary tee, a secondary pipe, an aeration disc connecting pipe, and aeration discs. The air inlet pipe is connected to the main pipe via the main tee, the main pipe is connected to the secondary pipe located in the middle via the secondary tee, and the main pipe is connected to the secondary pipe located on the outside via an elbow. Each secondary pipe has a row of aeration discs installed at intervals via the aeration disc connecting pipe. The main pipe and secondary pipes are arranged in a frame shape and fixed to the top of the frame by pipe supports.

[0007] Furthermore, the tie rod includes multiple tie rods, one end of which converges and connects at the top center of the frame, and the other end of each tie rod is connected and fixed to the upper end of the frame.

[0008] Furthermore, protective railings are symmetrically fixed to the outside of the frame via railing posts. The protective railings are located on the outer ring of the aeration components, and the height of the protective railings is greater than the height of the aeration components.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The lifting aeration pipeline for sewage treatment of this utility model can slide vertically upward along the sliding column through the sliding sleeve, so that the aeration component as a whole rises to the top of the aeration tank. This allows the aeration pipeline to be inspected and maintained above the aeration tank without emptying the sewage in the aeration tank, making the maintenance of the aeration pipeline more convenient, safe and hygienic.
