Description

Technical Field

[0001] This utility model belongs to the field of aeration disc technology, and in particular relates to a microporous aeration disc that prevents clogging. Background Technology

[0002] Aeration discs are key components of aeration devices used in wastewater treatment to achieve efficient contact between gases (mainly air and oxygen) and liquids (water and wastewater).

[0003] Currently, in the wastewater treatment process, activated sludge and suspended impurities in the aeration tank tend to adhere to the surface of the micropores of the aeration discs. As the operating time increases, the impurities gradually accumulate and clog the micropores, leading to a decrease in aeration volume and uneven bubble distribution. This not only reduces oxygen utilization but also requires shutdown for disassembly and cleaning, increasing operation and maintenance costs and the risk of wastewater treatment interruption. Existing solutions mostly rely on manual periodic disassembly and cleaning or high-pressure water jet rinsing, which are cumbersome and easily damage the micropore structure of the aeration discs, making it difficult to achieve automatic cleaning.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 4As shown, a clog-resistant microporous aeration disc includes: an aeration disc body, the lower end of which is connected to an air supply pipe 4, and multiple aeration holes on the upper surface of the aeration disc; and a cleaning mechanism 2, which includes a rotating shaft 21 rotatably connected to the aeration disc body, the lower end of which passes through the aeration disc body and is located inside the air supply pipe 4, a drive wheel 26 fixedly mounted on the lower end of the rotating shaft 21, and multiple scraper arms 22 mounted on the upper end of the rotating shaft 21, with brushes 24 fixedly mounted on the lower end of each scraper arm 22, the brushes 24 being in contact with the upper surface of the aeration disc body.

[0023] The aeration disc body includes an aeration plate 1 and a lower shell 5. An aeration chamber is formed between the aeration plate 1 and the lower shell 5. Aeration holes are opened on the aeration plate 1. A connecting pipe 31 communicating with the aeration chamber is fixed at the lower end of the lower shell 5. The aeration chamber is connected to the air supply pipe 4 through the connecting pipe 31. The rotating shaft 21 is rotatably connected to the inner side of the connecting pipe 31 through the bearing 25.

[0024] Multiple scraper arms 22 are fixedly connected to a mounting ring at one end near the rotating shaft 21. A mounting post is fixedly provided at the upper end of the rotating shaft 21. The diameter of the mounting post is smaller than the diameter of the rotating shaft 21. The diameter of the mounting post matches the inner diameter of the mounting ring. The upper end of the mounting post has an external thread. A limit block 23 is connected to the outer thread of the upper end of the mounting post. The limit block 23 presses the mounting ring against the upper end surface of the rotating shaft 21.

[0025] In some embodiments, such as Figure 3 , 4 As shown, the aeration disc body is connected to the air supply pipe 4 through the connecting component 3. The connecting component 3 includes a receiving pipe 32 and a connecting pipe 31 at the lower end of the lower shell 5. The receiving pipe 32 is fixedly connected to the air supply pipe 4. The lower end of the receiving pipe 32 is connected to the air supply pipe 4. An installation hole 34 is opened on the side wall of the receiving pipe 32. A limiting rod 35 is provided in the installation hole 34. The limiting rod 35 passes through the installation hole 34 and protrudes from the inner side wall of the receiving pipe 32. An annular limiting groove 37 is opened on the outer side wall of the connecting pipe 31. A connecting groove 36 corresponding to the limiting rod 35 is opened on the outer side wall of the connecting pipe 31. An opening is opened on the lower end face of the connecting pipe 31. The upper end of the connecting groove 36 is connected to the annular limiting groove 37.

[0026] The connection process between the connecting pipe 31 and the receiving pipe 32 is as follows: When the connecting groove of the connecting pipe 31 is aligned with the insertion of the limiting pipe, the portion of the limiting rod 35 protruding from the inner wall of the receiving pipe 32 enters the inner side of the annular limiting groove 37 through the connecting groove. Rotating the connecting pipe 31 causes the portion of the limiting rod 35 protruding from the inner wall of the receiving pipe 32 to become misaligned with the connecting groove, thus completing the connection between the aeration disc body and the air supply pipe 4. The outer diameter of the connecting pipe 31 matches the inner diameter of the receiving pipe 32.

[0027] In other embodiments, the aeration disc body is connected to the air supply pipe 4 via a connecting assembly 3. The connecting assembly 3 includes a receiving pipe 32 and a connecting pipe 31 at the lower end of the lower housing 5. The receiving pipe 32 is fixedly connected to the air supply pipe 4, and its lower end is connected to the air supply pipe 4. A threaded hole is formed on the inner side wall of the receiving pipe 32, and a limiting bolt is threaded into the threaded hole. The limiting bolt protrudes from the inner side wall of the receiving pipe 32. An annular limiting groove 37 is formed on the outer side wall of the connecting pipe 31, and a communicating groove 36 corresponding to the limiting rod 35 is formed on the outer side wall of the connecting pipe 31. The communicating groove 36 has an opening on the lower end face of the connecting pipe 31, and its upper end is connected to the annular limiting groove 37. The outer diameter of the connecting pipe 31 matches the inner diameter of the receiving pipe 32. A sealing gasket is provided between the head of the limiting bolt and the outer side wall of the connecting pipe.

[0028] The connection process between the connecting pipe 31 and the receiving pipe 32 is as follows: when the connecting groove of the connecting pipe 31 is aligned with the insertion of the limiting pipe, the part of the limiting bolt protruding from the inner wall of the receiving pipe 32 enters the inner side of the annular limiting groove 37 through the connecting groove. Rotate the connecting pipe 31 so that the part of the limiting bolt protruding from the inner wall of the receiving pipe 32 is not aligned with the connecting groove, thus completing the connection between the aeration disc body and the air supply pipe 4.

[0029] In other embodiments, the connecting pipe 31 has external threads on its outer side, the receiving pipe 32 is fixedly connected to the gas supply pipe 4, the receiving pipe 32 is connected to the gas supply pipe 4, the receiving pipe 32 has internal threads on its inner side, and the connecting pipe 31 is threadedly connected to the receiving pipe 32.

[0030] The installation and disassembly of the aeration disc body are convenient, which improves the efficiency of aeration disc maintenance and replacement.

[0031] In some embodiments, a sealing ring 33 is provided between the receiving pipe 32 and the lower housing 5. The sealing ring 33 improves the sealing performance between the receiving pipe 32 and the lower housing 5 and prevents gas leakage.

[0032] In other embodiments, a sealing ring 33 is provided between the inner wall of the receiving pipe 32 and the outer wall of the connecting pipe. The sealing ring 33 improves the sealing between the receiving pipe 32 and the lower housing 5, preventing gas leakage.

[0033] In some embodiments, the drive wheel 26 is an open impeller located inside the connecting pipe 31. The airflow within the connecting pipe 31 drives the open impeller to rotate, which in turn drives the rotating shaft 21 and the scraper arm 22 to rotate.

[0034] In other embodiments, the drive wheel 26 is a turbine located inside the connecting pipe 31. The airflow within the connecting pipe 31 drives the turbine to rotate, which in turn drives the rotating shaft 21 and the scraper arm 22 to rotate.

[0035] In some embodiments, an annular boss is fixedly provided on the outer side of the upper end of the connecting pipe 31, and a reinforcing rib is fixedly provided on the outer side wall of the annular boss. The reinforcing rib is fixedly connected to the lower housing 5. The setting of the reinforcing rib improves the connection structure strength between the connecting pipe 31 and the lower housing 5.

[0036] In other embodiments, a hexagonal prism structure is fixed to the outer side of the upper end of the connecting tube 31, which facilitates the rotation of the lower housing using a handle.

[0037] The aeration disc body is a structural component made of PVC plastic. The scraper arm 22 is also a structural component made of PVC plastic. The PVC plastic aeration disc body and scraper arm 22 extend the service life of the aeration disc.

[0038] By setting up the cleaning mechanism 2, the micropores can be effectively prevented from being blocked by impurities during long-term use, ensuring the normal operation of the aeration device. By setting up the drive wheel 26, the flow of gas drives the rotating shaft 21 to rotate, which in turn drives the entire cleaning mechanism 2 to rotate, thus achieving the function of cleaning the outer surface of the aeration plate 1, saving energy and eliminating the need for a power cord.
