[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] The utility model provides Figure 1-5 The illustrated embodiment shows a high-efficiency and energy-saving submersible centrifugal aerator, comprising a centrifugal pump 4 and an aeration plate 3 disposed below the centrifugal pump 4.

[0041] A connecting hanger 5 is provided on the upper side of the centrifugal pump 4, a connecting plate 7 is provided on the right side of the aeration plate 3, and an air inlet pipe 8 is provided on the upper side of the connecting plate 7;

[0042] Connecting rods 2 are provided at the four corners of the lower side of the aeration plate 3, and a chassis 1 is provided at the lower bottom of the connecting rods 2;

[0043] A plurality of aeration pipes 6 are provided on the lower periphery of the aeration plate 3, and the centrifugal pump 4 is powered by connecting to an external power supply;

[0044] A fixing plate 12 is provided at the upper positions of the front and rear sides of the chassis 1. A spring cavity 13 is provided at the upper inner position of the fixing plate 12, and a clamping hole 17 is provided at the lower position of the fixing plate 12.

[0045] A compression spring 14 is provided at the upper inner side of the spring chamber 13 , a clamping block 18 is provided at the lower side of the compression spring 14 , a clamping plate 15 is provided between the two clamping blocks 18 , and sweeping rods 16 are provided at the front and rear sides of the clamping plate 15 respectively.

[0046] In this embodiment, this highly efficient and energy-saving submersible centrifugal aerator is exquisitely designed. Its main components include a centrifugal pump 4, aeration plate 3, connecting hanger 5, connecting plate 7, air inlet pipe 8, connecting rod 2, base plate 1, fixing plate 12, spring chamber 13, compression spring 14, clamping block 18, clamping plate 15, and sweeping rod 16. The following is a detailed description of the aerator structure:

[0047] Centrifugal pump 4: Located at the upper part of the entire device, it is responsible for driving the aeration disc 3 to rotate and obtains electricity by connecting to an external power supply.

[0048] Aeration plate 3: Installed below the centrifugal pump 4, it is the main part of aeration. There are multiple aeration pipes 6 distributed around it to disperse air into the water.

[0049] Connecting hanger 5: fixed on the top of centrifugal pump 4, plays the role of suspending and supporting the entire equipment.

[0050] Connecting plate 7 and air inlet pipe 8: The connecting plate 7 is located on the right side of the aeration plate 3, and an air inlet pipe 8 is provided above it for introducing air into the aeration system.

[0051] Connecting rods 2 and chassis 1: Four connecting rods 2 extend from the four corners below the aeration plate 3 to the chassis 1. The chassis 1 serves as a basic support to stabilize the entire aerator.

[0052] Fixed plate 12 and spring cavity 13: Fixed plates 12 are installed above the front and rear sides of the chassis 1. A spring cavity 13 is provided inside the fixed plate 12 for accommodating a compression spring 14 and a clamping block 18.

[0053] Compression spring 14 and clamping block 18 : The compression spring 14 is located above the inner side of the spring cavity 13 , and its lower end is connected to the clamping block 18 . The clamping block 18 can move up and down in the spring cavity 13 to control the clamping plate 15 .

[0054] Card plate 15 and sweeping rod 16: A card plate 15 is provided between the two card blocks 18, and sweeping rods 16 are installed on both sides of the card plate 15. The design of the sweeping rod 16 enables it to protrude from the card plate 15 and be inserted into the card hole 17 on the fixed plate 12 to realize the fixing, cleaning and adjustment functions.

[0055] Additional components of the intake pipe 8: The top periphery of the intake pipe 8 is equipped with multiple connecting threads 9 for connecting a thick sleeve 11 and a rubber tube 10. The rubber tube 10 has good toughness, which is easy to connect and adapt to different environments, while the thick sleeve 11 is tightly connected to the intake pipe 8 through the connecting threads 9.

[0056] The working principle of this submersible centrifugal aerator is based on the centrifugal force generated by the high-speed rotation of the impeller in the aeration disk 3 on the lower side of the centrifugal pump 4. When the impeller rotates, a strong negative pressure is formed at its inlet, sucking in air and water. This air and water are mixed into a certain proportion of air-water mixture in the mixing chamber. Under the action of the strong centrifugal force, the air-water mixture is ejected outward from the aeration pipe 6 along the tangential direction of the impeller and diffuses in the circumferential direction. In this way, the water flow forms a convection cycle, and the fine micro-bubbles have a large specific surface area and a slow rise rate, ensuring that they are fully mixed with the water, thereby achieving the effect of efficient oxygenation and aeration.

[0057] like Figure 1-5 As shown, the sweep rod 16 protrudes from the card plate 15, and the sweep rod 16 and the card block 18 are respectively connected to the card plate 15 through an integrated connection method, the card block 18 is connected to the spring cavity 13 through an embedded connection method, and the card block 18 can move up and down in the spring cavity 13, the compression spring 14 is respectively connected to the card block 18 and the fixed plate 12 through a bolt connection method, and the sweep rod 16 can be embedded in the card hole 17 through an embedded connection method.

[0058] Preferably, the operator can connect the centrifugal pump 4 to the upper connecting hook 5 through an external suspension device to suspend the device and immerse it in the liquid. The card plate 15 on the lower middle side of the chassis 1 contacts the ground at the bottom of the liquid, and the device is rotated by controlling the suspension rope. The rotating card plate 15 and the sweeping rod 16 at the extended position sweep the debris at the bottom of the liquid to one side. Then, the operator uses the gravity of the device itself and the ground to press the card plate 15, embeds the sweeping rod 16 of the card plate 15 into the card hole 17, and moves the card block 18 of the card plate 15 upward in the spring cavity 13 by pressing the compression spring 14, so that the overall height of the card plate 15 is lower than the height of the chassis 1, and is fixed on the ground at the bottom of the liquid that has been swept through the chassis 1.

[0059] like Figure 1 As shown, a rubber tube 10 is provided at the upper external position of the air intake pipe 8, a thick sleeve 11 is provided at the upper position of the rubber tube 10, and a plurality of connecting threads 9 are provided at the upper external position of the air intake pipe 8. The thick sleeve 11 can be connected to the air intake pipe 8 through the connecting threads 9. The rubber tube 10 is connected to the thick sleeve 11 and the air intake pipe 8 respectively through a threaded connection, and the rubber tube 10 has the characteristic of strong toughness. The connecting hanger 5 is connected to the upper side of the centrifugal pump 4 through an integrated connection method, and the four connecting rods 2 are connected to the chassis 1 and the aeration plate 3 respectively through an integrated connection method.

[0060] Preferably, when the operator uses the device to add gas to the liquid, the operator can achieve a better aeration effect by bending the rubber tube 10 to connect the thick sleeve 11 and the external air pumping equipment. The operator can also fold the rubber tube 10 into the thick sleeve 11 and connect the thick sleeve 11 to the air inlet pipe 8 using the connecting thread 9 to extend the length of the air inlet pipe 8, so as to use it in water bodies with too high liquid levels.

[0061] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
