Description

Technical Field

[0001] This utility model relates to the field of oxygenation equipment technology, and in particular to a stirring type oxygenation equipment. Background Technology

[0002] Agitator-type aerators are devices that promote gas-liquid mixing and increase dissolved oxygen content in water through mechanical agitation. They are widely used in aquaculture, wastewater treatment, and aquatic ecosystem restoration. Their core principle is to utilize the high-speed rotation of an impeller or propeller to generate shear force in the water flow, cutting air into tiny bubbles and dispersing them evenly into the water, while simultaneously driving water circulation to achieve efficient oxygenation and mixing.

[0003] By comparing a device for ecological restoration of polluted river water with patent publication number CN220201652U, it was found that in this solution, a hydraulic cylinder drives the mounting frame to move up and down, which in turn drives the aeration plate to move up and down. A rotating motor drives the aeration plate to rotate, and an air pump injects oxygen into the aeration plate, allowing the aeration head to spray gas in different directions. However, the oxygen released by the device is not effectively cut and stirred, and cannot form a large number of small bubbles, reducing the contact area between oxygen and liquid, thus reducing the dissolved oxygen content. At the same time, the aeration head is not adequately protected, and dead branches and leaves in the water may clog the aeration head, reducing the aeration efficiency. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-4 As shown, a stirring aerator includes a mounting plate 100, a float plate 200 mounted on the edge of the mounting plate 100, and a stirring mechanism for aerating and stirring water source, the stirring mechanism being located below the mounting plate 100.

[0026] In this embodiment: the stirring mechanism includes a connecting cover 302 disposed at the bottom of the mounting plate 100, a connecting pipe 301 fixed at the bottom of the connecting cover 302, and an exhaust cover 309 fixed at the bottom of the connecting pipe 301. The exhaust cover 309 is a cone shape with its lower end facing upwards. Multiple exhaust pipes 310 are provided on the surface of the exhaust cover 309. The multiple exhaust pipes 310 are spirally distributed around the center of the exhaust cover 309. A waterproof cover is installed on the right side of the connecting cover 302. A drive shaft 308 is rotatably mounted at the bottom of the waterproof cover. A drive motor 321 is mounted on the rotating end of the drive shaft 308. The output end of the drive motor 321 is connected to the drive shaft 308 via a coupling. The rotating end of 08 is fixed. Both the connecting pipe 301 and the drive shaft 308 are equipped with pulleys. The two pulleys are driven by a drive belt. A venting groove 303 is provided above the mounting plate 100 near the connecting cover 302. Multiple venting holes 304 are provided at the bottom of the venting groove 303. An air inlet cover 305 is installed at the upper end of the venting groove 303. The air inlet cover 305 is connected to the mounting plate 100 by bolts. An air pump 306 is provided on the right side of the air inlet cover 305. An air inlet pipe 307 is connected between the air pump 306 and the air inlet cover 305. An agitation structure for agitating the discharged air is provided above the air outlet cover 309.

[0027] The agitation structure includes a rotating shaft 311 disposed inside the connecting pipe 301. The rotating shaft 311 is rotatably connected to the mounting plate 100 and the air outlet hood 309. An air inlet gap is left between the rotating shaft 311 and the connecting pipe 301. A rotary motor 322 is mounted on the rotating end of the rotating shaft 311. The output end of the rotary motor 322 is fixed to the rotating end of the rotating shaft 311 via a coupling. A turntable 312 is fixed to the bottom end of the rotating shaft 311. The upper part of the turntable 312 is close to the air outlet hood 309. Multiple connecting plates 313 are provided at the edge of 09, and the multiple connecting plates 313 are distributed around the center of the turntable 312. A rotating plate 315 is installed at the top of the connecting plate 313. The rotating plate 315 is parallel to the side wall of the air vent 309. A rotating sleeve 319 is fixed in the middle of the connecting pipe 301. Multiple levers 320 are installed around the side wall of the rotating sleeve 319. The levers 320 are made of silicone. A protective structure for protecting the rotating plate 315 is provided at the edge of the turntable 312.

[0028] The protective structure includes a protective cover 316 located at the edge of the turntable 312. The protective cover 316 is rotatably connected to the connecting pipe 301. The protective cover 316 is made of rubber and is a cone shape with the small end facing upwards. Multiple air outlets 317 are opened on the surface of the protective cover 316. Multiple cutting blades 318 are arranged around the side wall of the protective cover 316. A brush plate 314 is installed at the top of the rotating plate 315. Oxygen is injected into the water source through a stirring mechanism and the injected oxygen is stirred. The oxygen is then cut by the stirring structure, breaking large bubbles into multiple small bubbles and pushing the oxygen bubbles further away to increase the contact area between oxygen and water source and increase dissolved oxygen. At the same time, the protective structure protects the air outlet pipe 310, intercepts debris, and cuts dead branches and leaves in the water to prevent them from getting tangled on the surface of the protective structure, thereby improving the aeration efficiency.

[0029] Working principle: First, place the mounting plate 100 on the water surface and use the float plate 200 to float the device on the water surface. Then, start the air pump 306 to input oxygen into the air vent 303, which flows through the connecting cover 302 and the connecting pipe 301 and enters the air outlet cover 309. Then, use the multiple air outlet pipes 310 on the surface of the air outlet cover 309 to spray oxygen into the water. At the same time, start the drive motor 321 to drive the drive shaft 308 to rotate forward. Use the drive belt to drive the connecting pipe 301 to rotate, thereby driving the air outlet cover 309 to rotate, driving the multiple air outlet pipes 310 to rotate forward, causing the sprayed oxygen to spiral upward.

[0030] As oxygen is ejected, the rotary motor 322 is activated, causing the rotating shaft 311 to rotate in reverse, which in turn causes the turntable 312 to rotate, which in turn causes multiple connecting plates 313 to rotate, which in turn causes multiple rotating plates 315 to rotate in reverse. This causes the rotating plates 315 to rotate in the opposite direction to the air outlet pipe 310, so that the multiple rotating plates 315 have a shearing effect on the ejected oxygen bubbles. The rotating plates 315 break the large ejected oxygen bubbles into multiple small oxygen bubbles and push the oxygen bubbles further away to increase the contact area between oxygen and water, thereby increasing dissolved oxygen.

[0031] Simultaneously, the protective cover 316 can enclose multiple rotating plates 315 and the air outlet pipe 310, preventing debris in the water from covering their surfaces and preventing blockage of the air outlet pipe 310. While rotating, the multiple rotating plates 315 drive the brush plate 314 to rotate, which clears the multiple air outlets 317 on the surface of the protective cover 316, preventing debris from blocking the air outlets 317 and ensuring that the generated oxygen bubbles flow out of the protective cover 316. While rotating, the turntable 312 drives multiple cutting blades 318 to rotate, which cut dead branches and leaves in the water, preventing these impurities from getting entangled on the surface of the protective cover 316. When the connecting pipe 301 rotates, it drives multiple deflector plates 320 to rotate, which can push the oxygen bubbles in all directions of the water source, expanding the area of ​​the oxygen bubbles in the water source, allowing the oxygen bubbles to spread throughout the water body, and improving the aeration efficiency.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
