Description

Technical Field

[0001] This utility model relates to the field of aeration head technology, specifically a self-cleaning aeration head for water treatment. Background Technology

[0002] Aeration is a method of bringing air and water into strong contact. It involves dissolving oxygen from the air into the water or releasing unwanted gases and volatile substances from the water into the air. In water treatment systems, wastewater needs to be treated with aeration processes, and appropriate aeration heads are required for aeration treatment of wastewater.

[0003] However, existing aeration heads are not convenient to protect the first aeration hole during use, which makes it easy for impurities in the sewage to flow into the interior of the first aeration hole and cause blockage.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN216837354U discloses an easily replaceable water treatment system aeration head, comprising an aeration head body, a microporous filter membrane fitted on the outer wall of the aeration head body, and equally spaced first aeration holes on the inner wall of the aeration head body, one end of each first aeration hole extending to the outside of the aeration head body. An air inlet pipe is located at the center of the bottom of the aeration head body, with its top extending into the interior of the aeration head body. An air supply pipe is installed at the end of the air inlet pipe furthest from the aeration head body. A connecting seat is located above the microporous filter membrane, and fastening grooves are provided on the outer walls of both sides of the connecting seat. An outer protective cover is installed inside the fastening groove, with one end of the outer protective cover extending to the outside of the fastening groove. This design not only reduces the clogging of the first aeration holes during aeration head use, improving the convenience of using the aeration head, but also reduces air leakage during aeration head supply.

[0005] The aforementioned device uses an outer protective cover to reduce the clogging of the first aeration hole during use. However, the air inlet pipe of the aforementioned device transmits water for a long time, and impurities in the water are constantly flushed inside the pipe. When the pipe stops transporting water, the impurities are oxidized by air and accumulate on the inner wall of the pipe, causing the drain outlet to become blocked and affecting the use of the aeration head. Therefore, in actual use, impurities accumulate inside the pipe, causing the aeration head to become blocked. Utility Model Content

[0006] The purpose of this invention is to provide a self-cleaning aeration head for water treatment, so as to solve the problem mentioned in the background art of impurities accumulating inside the pipe and causing the aeration head to become clogged.
