Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, in particular to a butterfly-type jet aeration device. Background Art

[0002] In the wastewater treatment industry, the injection of aerobic microorganisms into wastewater is essential. This process, in essence, oxidizes organic pollutants in the wastewater and decomposes them into more stable inorganic substances. During aerobic wastewater treatment, aeration devices continuously supply dissolved oxygen to the wastewater. The aeration system also aerates the wastewater while supplying air, allowing the wastewater in the tank to fully contact the aerobic components in the air. This accelerates the transfer of oxygen from the air into the wastewater, thereby speeding up the dissolution of organic pollutants and microorganisms and significantly improving wastewater treatment efficiency.

[0003] Wastewater treatment often requires the addition of reactants to the wastewater. Existing aeration devices only have a single aeration function, mixing the wastewater and the reactants through aeration. Unlike the simple air injection method, the reactants and the pollutants in the wastewater need to further react. Therefore, the simple aeration method leads to low reaction efficiency between the reactants and pollutants. Summary of the Invention

[0004] The cam is secured to the top of the air duct and is adapted to engage the exhaust gas supply pipe of the air duct and to engage the exhaust gas supply pipe of the air duct in an unbalanced manner. The cam is pressed against the push plate to push the spring back against the push plate, and the cam is pressed against the push plate to push the spring back against the push plate.

[0005] As a further preferred embodiment, a push surface is provided on the push seat, and the push surface is arc-shaped. When the push seat is deflected upward to a horizontal position, the push surface is used to gradually squeeze the front end of the tamping rod and push the entire tamping rod backward.

[0006] As a further preference, a sleeve is fixed on the top surface of the hinged plate, the sleeve is located on the rear side of the guide seat, the spring is filled in the sleeve, the push plate is located in the sleeve, and the outer circular surface of the push plate is slidably fitted on the inner wall of the tube cavity of the sleeve.

[0007] As a further preferred embodiment, an assembly hole is provided on the blocking cover, a bearing is installed in the assembly hole, the stirring rod is assembled on the bearing, the impeller is located at the inner end of the stirring rod, the stirring rod gradually becomes longer as it moves away from the blocking cover, and a stirring rod is installed on the stirring rod, and the stirring rod is bent up and down in a manner parallel to the outer periphery of the stirring rod.

[0008] As a further preferred embodiment, an ear protruding to one side is provided on the edge of the stop cover, an assembly hole is opened on the ear, a bearing is mounted on the ear through the assembly hole, and the stirring rod is mounted on the ear through the bearing in a manner deviated from the center of the stop cover, and by deviating from the center of the stop cover, the impeller deviates to the side of the pipe mouth of the aeration pipe.

[0009] As a further preference, there are multiple stirring rods arranged in a ring array on the stirring rods, all the blocking covers are equipped with a stirring rod of the same structure, and each stirring rod is equipped with an impeller close to the aeration pipe orifice.

[0010] As a further preferred embodiment, an oblique opening is provided on the blocking cover, and when the blocking cover is rotated upward to a horizontal position, the oblique opening is away from the front side of the pipe opening of the aeration pipe.

[0011] As a further preference, the blocking cover is a plastic cover, the stirring rod is a solid plastic rod, and the pushing seat is a solid rubber seat.

[0012] The beneficial effects of the present invention compared to the prior art are:

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

[0014] A stirring rod is provided on the baffle. When the aeration pipe is aerated outward, the baffle rotates upward so that the front surface of the baffle becomes the top surface against the bottom front end of the guide seat and remains horizontal. The baffle drives 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 greater, ensuring that the baffle 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 drives the stirring rod to rotate, and the stirring rod drives 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 generated by 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 enable the aerobic molecules from the aeration to be fully mixed with the pollutants in the wastewater. Secondly, the added reactants are dissolved in the pollutants more efficiently, so that the impregnation substances 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 circular manner, so that the wastewater in the area is efficiently treated, further improving the wastewater treatment efficiency.

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

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

[0025] The present embodiment provides a butterfly jet aeration device, comprising an aeration seat 1, a circle of aeration tubes 2 are installed in a ring array on the aeration seat 1, 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, the outer end of the hinged plate 3 is installed with a swivel seat 4 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 outward with high pressure, gas is blown into the sinking cavity 6, and the sinking cavity 6 pushes the baffle 5 to deflect upward, 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 The front side of the seat 9 extends beyond the nozzle of the aeration pipe 2. The other end of the tamping rod 10 passes through 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 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, causing the tamping rod 10 to move 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 cover 5. The front end length of the guide seat 9 exceeds the front end of the hinged plate 3. When the cover 5 rotates downward to cover the nozzle of the aeration pipe 2, it rotates downward with the stirring rod 13 to the horizontal. When the cover 5 rotates upward, it is positioned horizontally by the front end of the guide seat 9, and at the same time drives the stirring rod 13 to rotate vertically. An impeller 14 is installed on the stirring rod 13. The impeller 14 is located on the inner side of the cover 5. When the stirring rod 13 rotates to vertical, the impeller 14 is vertical to the front side of the nozzle 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 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 on 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 as it moves away from the blocking cover 5, and a stirring rod 17 is installed on the stirring rod 13. 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 retaining cover 5, an assembly hole is provided on the ear 51, a bearing is mounted on the ear 51 through the assembly hole, and the stirring rod 13 is mounted on the ear 51 via the bearing in a manner deviated from the center of the retaining cover 5. By deviating from the center of the retaining 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 arranged in a circular array on the stirring rod 13. All the retaining covers 5 are equipped with a stirring rod 13 of the same structure. Each stirring rod 13 is equipped with an impeller 14 near the nozzle of the aeration pipe 2. The stirring rods 17 are not limited to the L-shape shown in the figure, but can also have other shapes. Their 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, put the entire aeration device into the wastewater pool, start the aeration device, aerate the wastewater through the aeration pipe 2, so that the wastewater produces a surging effect, add a reactant into the wastewater, and mix it with the oxygen component injected during aeration to speed up 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 existing technology 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 and remains horizontal. 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 vertically by the stirring rod 13 in the aeration The area near the orifice of the trachea 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, which in turn 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 action generated by the stirring rod 17 acts on the wastewater. After the gas discharged from the aeration pipe 2 acts on the wastewater, it flows 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, 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 substances are quickly neutralized and decomposed. The stirring rods 13 are arranged in a circular array on each aeration tube 2. Therefore, when these aeration tubes 2 aerate the wastewater with high pressure, these 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: even if the gas pressure discharged from the aeration pipe 2 is not sufficient to push the baffle 5 to a completely horizontal position due to equipment factors, the stirring rod 13 and the stirring sub-rod 17 may rotate in the wastewater in an inclined manner under the drive of the baffle 5. At this time, the stirring sub-rod 17 is in a farther position relative to the wastewater generating bubbles when aerated by the aeration pipe 2, and can also produce a stirring effect on the wastewater. Therefore, the air pressure and water pressure acting on the baffle 5, even if the baffle 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. The stirring structure is hinged with the baffle 5 in this way, and the application is more flexible.

[0034] like Figure 2As shown, when the stop cover 5 is deflected upward, it will deflect the push seat 7 backward, 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. 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 its elastic force, and the push plate 12 drives the tamping rod 10 forward. The front end of the tamping rod 10 pushes the push seat 7, and the push seat 7 pushes the stop cover 5 to deflect to the pipe mouth of the aeration pipe 2, and the aeration pipe 2 is quickly closed. When aeration is completed, the aeration pipe 2 is quickly closed in this way to prevent sludge from flowing back into the aeration pipe 2 and causing blockage of the pipe lumen.

[0035] An ear portion 51 protruding to one side is provided on the edge of the baffle 5, and the stirring rod 13 is actually mounted on the ear portion 51 of the baffle 5 via 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 from 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, ensuring that the impeller 14 rotates effectively and has a reasonable structure.

[0036] The retaining cap 5 is a plastic cap, 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 venting, sufficient air and water pressure pushes the retaining cap 5 open, while ensuring that the retaining cap 5 and the stirring rod 13 rotate effectively. When the venting pressure of the aeration pipe 2 is increased, sufficient air and water pressure rotates the retaining cap 5 to a horizontal position, which in turn rotates the stirring rod 13 to a vertical position. As long as the venting pressure of the aeration pipe 2 does not decrease, the retaining cap 5 remains horizontal, and the retaining cap 5 and the stirring rod 13 remain in a vertical position.

[0037] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. 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 based on their actual installation and actual use, as well as the customary orientations of those skilled in the art. This is hereby explained.

[0038] The specific embodiments described above further illustrate the purpose of the present invention, technical solutions, and beneficial effects. It should be understood that the above description is merely a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. In particular, it should be noted that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
