Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a vortex high-efficiency aeration device. Background Technology

[0002] Aeration devices are the core equipment in water treatment systems for oxygenating water bodies, and their performance directly affects the biochemical reaction efficiency of wastewater treatment and the dissolved oxygen concentration in aquaculture water bodies.

[0003] Existing aeration devices produce bubbles with large diameters, which rise quickly in the water and have short residence times, resulting in oxygen escaping to the surface before it is fully dissolved.

[0004] An existing patent (publication number: CN216687646U) discloses a swirl aeration device. A guide vane is placed inside a sleeve, and multiple first toothed covers and multiple second toothed covers are staggered and installed inside the sleeve. An aeration pipe is installed inside a limiting sleeve. This facilitates the delivery of air through the aeration pipe to the area below the guide vane. The air is separated into several bubbles by the aeration pipe and then conveyed by the swirl vanes to the multiple first and second toothed covers. There, the air is sheared into numerous microbubbles by the first and second wedge-shaped teeth and delivered to the water in the upper aeration tank. This facilitates the aeration and uniform mixing of sludge in the tank water, and also facilitates the replacement of components such as the first and second toothed covers, the guide vane, and the sleeve, ensuring long-term use of the aeration device and extending its service life.

[0005] Existing patents offer solutions to the aforementioned problems, but their aeration effects are poor. In actual use, due to the lack of a mixing structure, the system relies solely on the natural rise of bubbles to cause slight disturbances in the water flow, failing to form an active water circulation. During wastewater treatment, activated sludge tends to deposit at the bottom of the tank, resulting in insufficient contact with the sheared microbubbles, which severely affects the wastewater treatment effect and reduces the practicality of the device.

[0006] Therefore, a high-efficiency swirl aeration device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a high-efficiency vortex aeration device that can solve the problems of poor aeration effect of existing aeration devices. In actual use, due to the lack of a mixing structure, the devices rely solely on the natural rise of bubbles to slightly disturb the water flow, which cannot form an active water circulation. In sewage treatment, activated sludge is prone to deposit at the bottom of the tank, and the contact with the sheared microbubbles is insufficient, which seriously affects the sewage treatment effect and reduces the practicality of the device.

[0025] 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.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A high-efficiency swirl aeration device includes a cross plate 1. Each of the four corners of the cross plate 1 has a fixing hole 2, and an aeration component 3 is fixedly connected inside the fixing hole 2. A mixing component 4 is fixedly connected to the bottom of the cross plate 1, and the four aeration components 3 are respectively fixedly connected to the four corners of the top of the mixing component 4. The mixing component 4 includes a cross base 401. Each of the four corners of the top of the cross base 401 has a mounting cylinder 402 fixedly connected, and a magnetic positioning block 403 is fixedly connected inside the mounting cylinder 402. A rotating rod 404 is rotatably connected to the top of the cross base 401, and a spiral blade 405 is sleeved on the surface of the rotating rod 404. The top of the rotating rod 404 extends to the top of the cross plate 1 and is fixedly connected to a rotating motor 406. The bottom of the rotating rod 404 extends into the interior of the cross base 401 and is fixedly connected to a main drive gear 407. A secondary drive gear 408 is fixedly connected to the bottom of each of the four mounting cylinders 402, and a chain 409 is wound between the main drive gear 407 and the four secondary drive gears 408.

[0028] In this embodiment: the cooperation between the jet pipe 304 and the mounting cylinder 402 forms a guiding structure, allowing the jet pipe 304 to move smoothly under the constraint of the mounting cylinder 402. Once in position, the locking block 303 engages with the slot 9 within the rotating ring 307, enabling rapid installation of the aeration assembly 3 and facilitating cleaning and maintenance. Simultaneously, the connecting hose 306 allows external air to be supplied to the jet pipe 304 for aeration, improving the ease of use of the aeration assembly 3. Then, the rotating motor 406 drives the rotating rod 40... 4. Rotation drives the spiral blades 405 to rotate, which in turn causes the wastewater to flow along the axis, ensuring thorough mixing of wastewater and air bubbles and guaranteeing the wastewater treatment effect. Simultaneously, in conjunction with the transmission structure consisting of the main drive gear 407, the secondary drive gear 408, and the chain 409, the rotating rod 404 drives the main drive gear 407 to rotate, and under the transmission of the chain 409, the secondary drive gear 408 and the mounting cylinder 402 rotate in tandem, which in turn drives the jet pipe 304 and the dispersing blades 305 to rotate, completing secondary mixing, ensuring the aeration effect, and improving the practicality of the device.

[0029] Specifically, such as Figure 5As shown, the aeration assembly 3 includes a fixed pipe 301, a fixed circular plate 302 is provided on the top of the fixed pipe 301, and a snap-fit ​​block 303 is fixedly connected to the top of both sides of the fixed pipe 301. An air jet pipe 304 is fixedly connected inside the fixed circular plate 302, and several dispersing blades 305 are fixedly connected to the surface of the air jet pipe 304. A connecting hose 306 is rotatably connected to the top of the air jet pipe 304, and the air jet pipe 304 is embedded in the mounting cylinder 402. A rotating ring 307 is rotatably connected to the surface of the fixed circular plate 302, and the rotating ring 307 engages with the snap-fit ​​block 303.

[0030] Specifically, such as Figure 3 As shown, a fixed bracket 5 is fixedly connected to the top of the cross plate 1, and a gas storage plate 6 is fixedly connected to the top of the fixed bracket 5. A gas transmission pipe 7 is fixedly connected to the top of the gas storage plate 6, and mounting holes 8 for use with connecting hoses 306 are opened at the four corners of the gas storage plate 6.

[0031] Specifically, such as Figure 5 As shown, both sides of the bottom of the rotating ring 307 are provided with slots 9 for use with the buckle block 303, and the surface of the buckle block 303 is in contact with the inner wall of the slot 9.

[0032] In this embodiment: the engagement structure can be formed by the cooperation of the snap-fit ​​block 303 and the slot 9, so that the rotating ring 307 drives the slot 9 to rotate smoothly along the snap-fit ​​block 303, thus fixing the jet pipe 304 to the cross plate 1. At the same time, the connection hose 306 is tightly connected to the air storage plate 6 by the cooperation of the connection hose 306 and the mounting hole 8. Together with the air storage plate 6 and the air supply pipe 7, a centralized air supply structure can be formed, which can evenly distribute the gas from the external air source to the four aeration components 3, ensuring that the four jet pipes 304 spray smoothly and stably, avoiding uneven aeration, ensuring the aeration effect, and improving the ease of use of the aeration components 3.

[0033] Specifically, such as Figure 4 As shown, the cross base 401 has a cross fixing groove 10 inside, and the main drive gear 407, the auxiliary drive gear 408, and the chain 409 are located inside the cross fixing groove 10.

[0034] Specifically, such as Figure 3 As shown, the bottom of the jet pipe 304 is provided with a positioning groove 11 for use with the magnetic positioning block 403, and the surface of the magnetic positioning block 403 is in contact with the inner wall of the positioning groove 11.

[0035] In this embodiment, the magnetic positioning block 403 and the positioning groove 11 work together to form a guiding structure, allowing the jet pipe 304 to move smoothly along the magnetic positioning block 403. This ensures the stability of the jet pipe 304 installation and utilizes the magnetic force of the magnetic positioning block 403 to complete the initial positioning, facilitating the installation of the aeration component 3. At the same time, under the action of the cross fixing groove 10, it provides operating space for the transmission structure composed of the main drive gear 407, the secondary drive gear 408, and the chain 409, preventing external forces from affecting the power transmission, ensuring the stable operation of the mixing component 4, and improving the ease of use of the mixing component 4.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, triangular reinforcing plates 12 are fixedly connected to the four corners of the cross plate 1 and the cross base 401.

[0037] Specifically, such as Figure 4 As shown, a fixing plate 13 is fixedly connected to each of the four corners of the cross base 401, and a fixing bolt 14 is connected to the internal thread of the fixing plate 13.

[0038] In this embodiment: the fixing plate 13 and the fixing bolt 14 are used together to make the fixing bolt 14 pass through the fixing plate 13 and be threaded to the bottom of the pool, thus completing the tight connection of the device. The reinforcement structure formed by the triangular reinforcing plate 12 can enhance the stability of the cross plate 1 and the cross base 401 structure, effectively resist external impact, avoid deformation or breakage, ensure the stable operation of the device, and improve the stability of the device.

[0039] Working Principle: When treating wastewater, first, tighten the fixing bolt 14 to connect it through the fixing plate 13 to the bottom of the tank via a threaded connection. This effectively resists external impacts and prevents shaking. Next, connect the air supply pipe 7 to an external air source to complete the initial preparation. During aeration, the external air source is activated to generate gas. The gas flows through the air supply pipe 7, the air storage plate 6, and the connecting hose 306, finally flowing into the jet pipe 304, forming a centralized air supply structure. This allows the gas from the external air source to be evenly distributed to the four aeration components 3, preventing uneven aeration and ensuring effective aeration. During aeration, the rotating motor 406 is activated to drive the rotating rod 404 to rotate, which in turn drives the spiral blades 405 and the main rotating gear to rotate. It can drive the sewage to flow along the axis, achieving initial mixing of sewage and air bubbles. It can also use the transmission structure of chain 409 to synchronously drive the secondary transmission gear 408 and the mounting cylinder 402, thereby driving the jet pipe 304 and the dispersing blade 305 to rotate, performing secondary cutting and mixing of the gas-liquid mixture, further enhancing the aeration effect. After treatment, when maintenance is required on the aeration component 3, manually rotate the rotating ring 307, which synchronously drives the slot 9 to rotate along the buckle block 303, releasing the lock on the aeration component 3. The jet pipe 304 can then be pulled out for maintenance. After maintenance, the jet pipe 304 is reset, and the rotating ring 307 is manually rotated to lock it, restoring the aeration function and preparing for subsequent sewage treatment.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
