[0013] 1. A baffle is provided on the aeration pipe. When the aeration pipe stops aeration, the baffle is closed on the pipe opening to prevent silt from blocking the pipe cavity.

[0014] A stirring rod is provided on the baffle cover. When the aeration pipe is aerated outward, the baffle cover rotates upward so that the front surface of the baffle cover becomes the top surface against the bottom front end of the guide seat and remains horizontal. The baffle cover leads the stirring rod to deflect upward to vertical. The aeration pipe continuously exhausts high-pressure gas. After the high-pressure gas is discharged from the pipe mouth, the wastewater pressure in the area becomes larger, ensuring that the baffle cover always rotates upward and remains horizontal. At this time, the impeller is driven by the stirring rod to be vertical near the pipe mouth of the aeration pipe, and automatically rotates under the action of the high-pressure gas continuously discharged from the aeration pipe. The impeller leads the stirring rod to rotate, and the stirring rod leads the stirring rod to rotate. At this time Since the stirring rod is vertical, the stirring rod is also vertical in the wastewater. The rotating motion of the stirring rod acts on the wastewater. After the gas discharged from the aeration pipe acts on the wastewater, it flows over the front end of the baffle cover to generate bubbles on the surface of the wastewater. When the bubbles rise from the bottom of the water to the surface, they pass through the stirring rod and the stirring rod. The stirring effect of aeration and the stirring rod on the wastewater works together to fully mix the aerobic molecules from the aeration with the pollutants in the wastewater, and to more efficiently dissolve the added reactants in the pollutants, so that the pollutants are quickly neutralized and decomposed.

[0015] 2. The stirring rods are arranged in a circular array on each aeration tube. Therefore, when these aeration tubes aerate the wastewater with high pressure, these stirring rods are arranged in a circle, so that the wastewater in the area can be efficiently treated, further improving the wastewater treatment efficiency.

DETAILED DESCRIPTION

[0023] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0024] In one embodiment, Figure 1-Figure 6 As shown:

[0025] The present embodiment provides a butterfly jet aeration device, comprising an aeration seat 1, on which a circle of aeration tubes 2 are installed in a circular array, a hinged plate 3 is welded on the top of the aeration tube 2, the outer end of the hinged plate 3 reaches the pipe mouth of the aeration tube 2, a swivel seat 4 is installed on the outer end of the hinged plate 3 through a hinge shaft, a baffle 5 is fixed on the swivel seat 4, when the swivel seat 4 deflects downward around the hinge shaft, the baffle 5 is closed on the pipe mouth of the aeration tube 2, a sinking cavity 6 is provided on the side of the baffle 5 facing the pipe mouth of the aeration tube 2, when the pipe mouth of the aeration tube 2 is aerated outwardly under high pressure, gas is blown into the sinking cavity 6, and the baffle 5 is pushed upward by the sinking cavity 6, a push seat 7 is fixed on the outside of the baffle 5, a spring assembly 8 is fixed on the top of the hinged plate 3, the spring assembly 8 comprises a guide seat 9 fixed on the top surface of the hinged plate 3, a tamping rod 10 penetrating the guide seat 9, and a spring 11 fixed on the top surface of the hinged plate 3, one end of the tamping rod 10 penetrates to the guide seat 9 The front side of the seat 9 extends to the outside of the pipe mouth of the aeration pipe 2. The other end of the tamping rod 10 penetrates the rear side of the guide seat 9 and is fixed with a push plate 12. The spring 11 is located on the rear side of the push plate 12. When the baffle cover 5 deflects the push seat 7 upward to a horizontal position, the rear end of the push seat 7 squeezes the front end of the tamping rod 10, so that the tamping rod 10 moves backward with the push plate 12, and the spring 11 is compressed and shortened by the pressure of the push plate 12. A stirring rod 13 is installed on the baffle cover 5. The front end length of the guide seat 9 exceeds the front end of the hinged plate 3. When the baffle cover 5 rotates downward to cover the pipe mouth of the aeration pipe 2, it rotates downward with the stirring rod 13 to the horizontal. When the baffle cover 5 rotates upward, it is positioned by the front end of the guide seat 9 and is in the horizontal position. At the same time, the stirring rod 13 is driven to rotate to the vertical. An impeller 14 is installed on the stirring rod 13. The impeller 14 is located on the inner side of the baffle cover 5. When the stirring rod 13 rotates to the vertical, the impeller 14 is vertical to the front side of the pipe mouth of the aeration pipe 2.

[0026] The push seat 7 is provided with a push surface 71 which is arc-shaped. When the push seat 7 is deflected upward to a horizontal position, the push surface 71 gradually squeezes the front end of the ramming rod 10 to push the entire ramming rod 10 to move backward.

[0027] like Figure 4 As shown, a sleeve 15 is fixed on the top surface of the hinged plate 3, the sleeve 15 is located at the rear side of the guide seat 9, the spring 11 is filled in the sleeve 15, the push plate 12 is located in the sleeve 15, and the outer circular surface of the push plate 12 is slidably fitted on the inner wall of the tube cavity of the sleeve 15.

[0028] like Figure 1 , Figure 2 As shown, an assembly hole is opened on the blocking cover 5, and a bearing 16 is installed in the assembly hole. The stirring rod 13 is assembled on the bearing 16, and the impeller 14 is located at the inner end of the stirring rod 13. The stirring rod 13 gradually becomes longer in a manner of moving away from the blocking cover 5, and a stirring rod 17 is installed on the stirring rod 13, and the stirring rod 17 is bent up and down in a manner parallel to the outer periphery of the stirring rod 13.

[0029] An ear 51 protruding to one side is provided on the edge of the baffle cover 5, an assembly hole is opened on the ear 51, a bearing is installed on the ear 51 through the assembly hole, and the stirring rod 13 is installed on the ear 51 through the bearing in a manner deviated from the center of the baffle cover 5, and by deviating from the center of the baffle cover 5, the impeller 14 is deviated to the side of the pipe opening of the aeration pipe 2.

[0030] like Figure 2 As shown, there are multiple stirring rods 17, and the stirring rods 17 are arranged in a circular array on the stirring rods 13. All the retaining covers 5 are equipped with a stirring rod 13 of the same structure, and each stirring rod 13 is equipped with an impeller 14 close to the pipe opening of the aeration pipe 2. The stirring rod 17 is not limited to the L-shape in the figure, but can also be other shapes, and its length is not limited to the proportional length in the figure, and can be flexibly changed according to the depth of the wastewater tank.

[0031] The blocking cover 5 is provided with an oblique opening 52 . When the blocking cover 5 is rotated upward to a horizontal position, the oblique opening 52 is away from the front side of the pipe opening of the aeration pipe 2 .

[0032] Working principle and effect: When in use, the entire aeration device is placed in the wastewater pool, the aeration device is started, and the wastewater is aerated through the aeration pipe 2 to make the wastewater produce a surging effect. A reactant is added to the wastewater and mixed with the oxygen component injected during aeration to accelerate the wastewater treatment efficiency. When the aeration pipe 2 aerates outward, the aeration pressure value is increased (the existing aeration equipment has a built-in pressure regulating function, which can be achieved through a pressure regulating valve, and the prior art is not repeated). The high-pressure gas pushes open the baffle cover 5, forcing the baffle cover 5 to rotate upward, so that the front of the baffle cover 5 becomes the top surface against the bottom front end of the guide seat 9 to remain horizontal, and the baffle cover 5 drives the stirring rod 13 to deflect upward to vertical, and the aeration pipe 2 continues to exhaust high-pressure gas. After the high-pressure gas is discharged from the pipe mouth, the wastewater pressure in the area becomes greater, ensuring that the baffle cover 5 always rotates upward and remains horizontal. At this time, the impeller 14 is driven by the stirring rod 13 to rotate vertically in the aeration The vicinity of the pipe opening of the air pipe 2 automatically rotates under the action of the high-pressure gas continuously discharged from the aeration pipe 2, and the impeller 14 rotates the stirring rod 13, and the stirring rod 13 rotates the stirring rod 17. At this time, since the stirring rod 13 is vertical, the stirring rod 17 is also vertical in the wastewater. The rotational movement generated by the stirring rod 17 acts on the wastewater. After the gas discharged from the aeration pipe 2 acts on the wastewater, it passes over the front end of the baffle 5 in a surging manner to generate bubbles (aeration) on the surface of the wastewater. When the bubbles rise from the bottom of the water to the surface of the water, they pass through the stirring rod 13 and the stirring rod 17. The aeration method and the stirring effect of the stirring rod 17 on the wastewater work together to enable the aerobic molecules from the aeration to be fully mixed with the pollutants in the wastewater, and secondly, the added reactants are more efficiently dissolved in the pollutants, so that the impregnation is quickly neutralized and decomposed. The stirring rods 13 are arranged in a circular array on each aeration tube 2. Therefore, when the aeration tubes 2 aerate the wastewater with high pressure, the stirring rods 13 are arranged in a surrounding manner, so that the wastewater in the area is efficiently treated, further improving the wastewater treatment efficiency.

[0033] It needs to be further explained that: due to equipment factors, even if the gas pressure discharged from the aeration pipe 2 is not sufficient to push the baffle cover 5 to a completely horizontal position, at this time, driven by the baffle cover 5, the stirring rod 13 and the stirring sub-rod 17 may rotate in the wastewater in an inclined manner. At this time, the stirring sub-rod 17 is rotated at a farther position relative to the wastewater generating bubbles upward during aeration by the aeration pipe 2, which can also cause the wastewater to produce a stirring effect. Therefore, the air pressure and water pressure acting on the baffle cover 5, even if the baffle cover 5 cannot be guaranteed to be absolutely horizontal and the stirring rod 13 cannot be absolutely vertical, the stirring sub-rod 17 is still in the wastewater to exert its stirring effect on the wastewater, and the stirring structure is hinged with the baffle cover 5 in this way, which is more flexible in application.

[0034] like Figure 2As shown, when the blocking cover 5 is deflected upward, it will deflect backward with the push seat 7, and the push surface 71 squeezes the front end of the tamping rod 10, so that the tamping rod 10 moves backward along the guide seat 9, and the tamping rod 10 moves the push plate 12 backward, and the push plate 12 squeezes the spring 11 to be compressed and shortened. When the aeration pressure is reduced or released, the spring 11 releases the elastic force, and the push plate 12 drives the tamping rod 10 forward, and the front end of the tamping rod 10 pushes the push seat 7, and the blocking cover 5 is deflected to the pipe mouth of the aeration pipe 2 by the push seat 7, so that the aeration pipe 2 is quickly closed. When aeration is completed, the aeration pipe 2 is quickly closed in this way, which can prevent sludge from flowing back into the aeration pipe 2 and causing blockage of the pipe cavity.

[0035] An ear portion 51 protruding to one side is provided on the edge of the baffle cover 5, and the stirring rod 13 is actually installed on the ear portion 51 of the baffle cover 5 through a bearing. The corresponding impeller 14 is arranged on the exhaust port of the aeration pipe 2 in a biased manner. That is, by utilizing this biased installation method, the impeller 14 is deviated to one side of the pipe port of the aeration pipe 2. When the aeration pipe 2 is exhausted outward, the gas and water pressure act on the blades in a biased force manner, thereby ensuring that the impeller 14 rotates effectively and has a reasonable structure.

[0036] The blocking cover 5 is a plastic cover, the stirring rod 13 is a solid plastic rod, and the push seat 7 is a solid rubber seat. When the aeration pipe 2 is exhausted, there is sufficient air pressure and water pressure to push the blocking cover 5 open, and at the same time, the blocking cover 5 is ensured to rotate effectively with the stirring rod 13. When the exhaust pressure of the aeration pipe 2 is increased, there is sufficient air pressure and water pressure to rotate the blocking cover 5 to the horizontal, and the stirring rod 13 is rotated to the vertical position by the blocking cover 5, and when the exhaust pressure of the aeration pipe 2 does not decrease, the blocking cover 5 is continuously horizontal, and the stirring rod 13 is continuously ensured to be in the vertical position by the blocking cover 5.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field.
