Description

Technical Field

[0001] This utility model relates to the field of nozzle cleaning technology, specifically to a jet aerator nozzle with self-cleaning function. Background Technology

[0002] Jet aerators are widely used in wastewater treatment, biological treatment, and other fields. Their core function is to draw in air through a high-speed water jet, breaking it into tiny bubbles. This allows oxygen to dissolve fully in the water, providing ample oxygen for microorganisms and promoting the decomposition and purification of organic matter. The jet aerator nozzle, a key component, works by: high-pressure water entering the nozzle housing through the inlet, being accelerated and shaped by a series of guiding structures (such as guide vanes and baffles), and then being ejected at high speed from the nozzle outlet, forming a powerful jet. Under the action of this jet, surrounding air is drawn in and thoroughly mixed with the water, achieving aeration. In practical applications, jet aerator nozzles are commonly used in urban wastewater treatment plants, industrial wastewater treatment stations, and aquaculture farms. For example, in urban wastewater treatment plants, large amounts of domestic sewage require biological treatment to remove organic matter and nutrients such as nitrogen and phosphorus. The jet aerator nozzle provides sufficient oxygen to the microorganisms in the activated sludge, ensuring the smooth progress of the biological treatment process.

[0003] Early jet aerator nozzles mostly adopted a single flow guiding structure, such as a straight cylinder or a simple conical design. Water entered through the inlet and was sprayed directly out of the nozzle. Although the structure was simple, the water flow pattern was unstable and the aeration efficiency was low. At the same time, in terms of cleaning methods, traditional equipment mostly relied on external cleaning devices for periodic rinsing. This not only required additional pipeline connections and control equipment, increasing the complexity of the system, but also made it difficult to clean both the inner and outer walls of the nozzle. Therefore, it is necessary to design a jet aerator nozzle with a self-cleaning function. Utility Model Content

[0004] The purpose of this invention is to provide a jet aerator nozzle with a self-cleaning function, which solves the technical problems of easy clogging inside the nozzle and scale buildup at the nozzle opening, thereby achieving the purpose of self-cleaning.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] Example 1:

[0022] Based on the existing problems of easy clogging inside the nozzle and scale buildup at the nozzle orifice, the present invention provides a preferred embodiment of a jet aerator nozzle with self-cleaning function, for example... Figure 1-4 As shown: A jet aerator nozzle with self-cleaning function includes an aerator nozzle housing 1, an inlet 2 at the top of the aerator nozzle housing 1, and a nozzle opening 3 at the bottom of the aerator nozzle housing 1; a cleaning component 4, which is disposed inside and outside the aerator nozzle housing 1 and the inlet 2; the cleaning component 4 includes: a first cleaning part 41, which is disposed inside the aerator nozzle housing 1; and a second cleaning part 42, which is disposed inside and outside the aerator nozzle housing 1 and the inlet 2, and is disposed outside and below the first cleaning part 41.

[0023] The cleaning part 41 includes: a rotating guide vane 411, which is located below the inlet 2 and inside the aerator nozzle housing 1; a spiral guide plate 412 is located below the rotating guide vane 411 and is fixedly installed on the inner wall of the aerator nozzle housing 1; a water-driven turbine 413 is located below the spiral guide plate 412 and is located inside the aerator nozzle housing 1, above the nozzle opening 3.

[0024] A mounting ring 414 is fixedly installed at the bottom of the water-driven turbine 413, and the mounting ring 414 is located inside the nozzle orifice 3. A micro rotating scraper 415 is fixedly installed at equal intervals around the outer wall of the mounting ring 414. A superhydrophobic biomimetic coating 416 is provided below the micro rotating scraper 415, and the superhydrophobic biomimetic coating 416 is sleeved on the outer wall and inner wall of the nozzle orifice 3.

[0025] Furthermore, in this embodiment, the rotating guide vanes 411 optimize the water flow state and improve aeration uniformity. Combined with the spiral guide plate 412, the water kinetic energy is enhanced, improving aeration efficiency. Then, the water-driven turbine 413 drives the micro-rotating scraper 415 to scrape away impurities on the inner wall of the nozzle orifice 3 in real time, effectively preventing the nozzle orifice 3 from clogging. Combined with the superhydrophobic biomimetic coating 416, the adhesion between impurities in the water flow and the wall surface is reduced, making it difficult for impurities to adhere, reducing the risk of clogging, and making subsequent cleaning easier.

[0026] Example 2:

[0027] Based on Embodiment 1, a preferred embodiment of the jet aerator nozzle with self-cleaning function provided by this utility model is, for example... Figure 1-4 As shown: Cleaning part 2 42 includes: an outer ring mounting plate 421, which is fixedly installed on the outer wall of the aerator nozzle housing 1; a connecting water ring box 422 is fixedly installed on the top of the outer ring mounting plate 421, the connecting water ring box 422 has a connecting port 423 on the top, and a connecting water pipe is connected inside the connecting port 423. A control water valve 424 is sleeved on the outer wall of the connecting water pipe, and the control water valve 424 is located above the connecting water ring box 422.

[0028] The inner sidewall of the outer ring mounting plate is provided with a mounting ring groove 425. A connecting water supply pipe 426 is connected to the outer wall of the water ring box 422, and the other end of the connecting water supply pipe 426 extends into the interior of the mounting ring groove 425. The other end of the connecting water supply pipe 426 is connected to an annular water pipe 427, and the annular water pipe 427 is fixedly installed inside the mounting ring groove 425.

[0029] The outer wall of the annular water pipe 427 is equidistantly connected with high-pressure spray heads 428, and the high-pressure spray heads 428 extend to the bottom of the nozzle orifice 3. The outer wall of the high-pressure spray heads 428 is fitted with a support ring plate 429, and the support ring plate 429 is fixedly installed at the bottom of the nozzle orifice 3. The bottom circumference of the support ring plate 429 is provided with locking holes 4210, and the locking holes 4210 are adapted to the support ring plate 429.

[0030] Furthermore, this embodiment ensures structural stability by setting an outer ring mounting plate 421, connecting the water ring box 422 and the annular water pipe 427, and achieving thorough cleaning of the nozzle opening 3 without dead angles through the high-pressure spray head 428, powerfully removing stubborn dirt attached to the outside. The supporting ring plate 429 enhances the stability of the spray head, and the locking hole 4210 facilitates fitting and installation, improving the deep cleaning effect. In conjunction with the cleaning part 41, it comprehensively ensures the cleanliness of the nozzle and extends the equipment life.

[0031] During normal aeration, water flows into the aerator nozzle housing 1 from inlet 2, first impacting the rotating guide vanes 411 located below inlet 2. The impact force of the water flow drives the rotating guide vanes 411 to rotate at high speed, initially guiding and cutting the incoming water flow, creating a more uniform swirling flow. Subsequently, the swirling water flow flows downward into the area of ​​the spiral guide plate 412. Since the spiral guide plate 412 is fixedly installed on the inner wall of the aerator nozzle housing 1, its spiral structure further enhances the swirling effect of the water flow, while accelerating the flow velocity, allowing the water flow to form a high-intensity rotating jet inside the housing.

[0032] Furthermore, the high-speed rotating water flow continues to move downwards, impacting the water-driven turbine 413 positioned above the nozzle orifice 3, causing the turbine to rotate synchronously. Driven by the turbine 413, the water flow gains stronger kinetic energy and is ultimately ejected at high speed through the nozzle orifice 3, completing the aeration process. During this process, the mounting ring 414 at the bottom of the turbine 413 rotates synchronously with the turbine. The micro-rotating scrapers 415 on the outer wall of the mounting ring 414 perform real-time light scraping of the inner wall of the nozzle orifice 3. Combined with the superhydrophobic biomimetic coating 416 on the inner and outer walls of the nozzle orifice 3, this reduces the adhesion of impurities in the water flow to the inner wall of the nozzle orifice 3, providing initial anti-clogging protection.

[0033] Furthermore, when deep self-cleaning is required, the control water valve 424 is opened, and external high-pressure cleaning water enters the connecting water ring box 422 through the connection port 423. The connecting water ring box 422 delivers the high-pressure water through the connecting water supply pipe 426 to the annular water pipe 427 in the mounting ring groove 425. The annular water pipe 427 evenly distributes the high-pressure water to the circumferentially spaced high-pressure spray heads 428. Under the fixing action of the support ring plate 429, the high-pressure spray heads 428 are precisely aimed at the bottom and outer area of ​​the nozzle opening 3, spraying high-pressure water to powerfully rinse the dirt attached to the outside of the nozzle opening 3.

[0034] Meanwhile, during the cleaning process, the water-driven turbine 413 continues to rotate, driving the micro-rotating scraper 415 to scrape the inner wall of the nozzle orifice 3 again, removing stubborn impurities remaining on the inner wall. The scraped-off impurities mix with the dirt rinsed off by the high-pressure spray head 428 and are discharged from the nozzle orifice 3 under the influence of the water flow. The superhydrophobic biomimetic coating 416 at this time reduces the adhesion between the impurities and the wall of the nozzle orifice 3, making it easier for the cleaned impurities to be carried away by the water flow, ensuring a thorough cleaning effect. After cleaning is completed, the control water valve 424 is closed, and the equipment can resume normal aeration operation.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
