[0021] 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.

[0022] See also Figure 1-2 , a high-efficiency self-priming agitator includes an inner ring 1 and an outer ring 2, and a plurality of connecting members 3 are connected between the inner ring 1 and the outer ring 2 at equal intervals in a circle, and a plurality of stirring members 4 are fixedly connected to the outside of the outer ring 2 at equal intervals in a circle. Due to the multiple distribution settings and high-speed rotation of the stirring members 4, the gas-liquid mixing effect is more uniform and efficient, the stirring member 4 is connected to the connecting member 3, the inner ring 1, the outer ring 2, the connecting member 3 and the stirring member 4 are integrally formed, the first side of the stirring member 4 is the liquid-facing surface 5, and the second side of the stirring member 4 is the liquid-receiving surface 6, and an exhaust port 7 is provided on the liquid-receiving surface 6. By arranging the exhaust port 7 on the liquid-receiving surface 6 and utilizing the negative pressure effect generated by the high-speed rotation of the liquid-facing surface 5, the gas on the liquid surface is sucked in and dispersed into the liquid phase, thereby improving the uniformity and efficiency of the gas-liquid mixing, accelerating the rate of the gas-liquid reaction, and reducing the complexity and cost of the equipment without the need for additional gas distribution equipment.

[0023] A fixing ring 9 is fixedly inserted into the inner ring 1, and the inner wall of the fixing ring 9 is provided with air intakes 8 at equal intervals around the circumference. The air intakes 8 are connected to the end of the connector 3 away from the outer ring 2. The gas on the liquid surface is sucked into the agitator through the exhaust port 7 and the air intake 8. The inhaled gas is dispersed and mixed into the liquid phase inside the agitator as the stirring member 4 rotates. The agitator continuously sucks in and disperses the gas into the liquid phase to form a circulating flow. This negative pressure adsorption method not only enhances the gas-liquid mixing effect, but also improves the uniformity and stability of the gas-liquid reaction.

[0024] The connecting member 3 and the stirring member 4 are hollow structures and are interconnected. When the stirrer rotates, the negative pressure formed at the liquid back surface 6 of the stirring member 4 due to the action of centrifugal force will suck the external gas through the exhaust port 7 and these hollow structures. Then, as the stirring member 4 rotates, the gas is brought into the liquid phase, achieving gas-liquid mixing.

[0025] A through groove is provided between the outer ring 2, the connecting member 3 and the stirring member 4. The cross section of the through groove is trapezoidal, which can guide the fluid to flow more smoothly and reduce the resistance and energy loss of the fluid during the flow process.

[0026] The outer diameter of the inner ring 1 is smaller than that of the outer ring 2, allowing the agitator to form different flow fields during rotation. The height of the outer ring 2 is greater than that of the inner ring 1, and the height of the fixed ring 9 is greater than that of the outer ring 2, increasing the agitation range and agitation intensity of the agitator, thereby improving agitation efficiency.

[0027] The liquid-facing surface 5 is arranged in an arc shape, which can reduce the resistance of the fluid on the liquid-facing surface 5, so that the fluid can flow through the stirring element 4 more smoothly, which can reduce the energy consumption of the stirrer and improve the stirring efficiency.

[0028] The back liquid surface 6 is arranged in a rectangular shape. The rectangular design enables the back liquid surface 6 to form a large negative pressure area when the agitator rotates. This negative pressure area helps to absorb external gas and achieve gas-liquid mixing.

[0029] Working Principle: When the agitator starts working, the stirring element 4 rotates at high speed, and the liquid-facing surface 5 contacts the liquid. Due to the centrifugal force, the liquid near the stirring element 4 is thrown to the surroundings, and a low-pressure area is formed on the liquid-receiving surface 6. The exhaust port 7 on the liquid-receiving surface 6 is connected to the external atmosphere, forming a pressure difference. Under the action of the pressure difference, the gas on the liquid surface is sucked into the agitator through the exhaust port 7 and the air inlet 8;

[0030] The inhaled gas is dispersed and mixed into the liquid phase inside the agitator as the stirring element 4 rotates. The agitator continuously inhales and disperses the gas into the liquid phase, forming a circulating flow. This negative pressure adsorption method not only enhances the gas-liquid mixing effect, but also improves the uniformity and stability of the gas-liquid reaction.
