Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more specifically, it relates to an environmentally friendly and efficient sewage treatment aeration device. Background Technique

[0002] During the sewage treatment process, by using certain methods and equipment, air is forcibly introduced into the sewage, so that the sewage in the pool comes into contact with the air for oxygenation, and the liquid is agitated to accelerate the transfer of oxygen in the air into the liquid, prevent the suspension in the pool from sinking, strengthen the contact between the organic matter in the pool, microorganisms and dissolved oxygen, and oxidize and decompose the organic matter in the sewage. This process of forcibly increasing oxygen in the sewage is called aeration.

[0003] In the sewage purification treatment process, mechanical stirring, aeration and oxygenation, and chemical agent dosing are the core links, and their synergistic effects directly affect the efficiency and stability of sewage treatment. In the traditional process, the mixer realizes solid-liquid mixing through the impeller shear force to prevent sludge deposition, the aerator injects air into the sewage through microporous diffusion or vortex shear to increase the dissolved oxygen concentration to activate the activity of aerobic microorganisms, and the chemical dosing machine quantitatively doses chemicals such as flocculants and denitrifying agents according to water quality parameters to strengthen pollutant removal.

[0004] However, the existing technology generally adopts a split equipment layout, resulting in the following problems: First, the energy consumption of the stirring and aeration systems is superimposed, and the power efficiency is low, and the escape rate of aeration bubbles in strong turbulence is relatively high; second, it is difficult to accurately match the chemical dosing point and the mixing intensity. In some areas, the chemical concentration is too high, which is likely to cause secondary pollution, and too low will lead to incomplete reactions.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, by forcibly introducing strong high-pressure gas into the aeration disc, the indoor sewage is brought into contact with air for oxygenation, and the liquid is stirred by the stirring shaft to accelerate the transfer of oxygen in the air to the liquid, strengthen the contact between the organic matter, microorganisms and dissolved oxygen in the room, and oxidize and decompose the organic matter in the sewage.

[0018] 2. In the present invention, the liquid medicine is uniformly exuded through the liquid outlet hole array on the surface of the shaft body by the driving of the pressure difference, and the instantaneous mixing of the medicine and the sewage is realized by means of the strong turbulent flow field formed by stirring, significantly improving the efficiency of chemical reactions such as flocculation and neutralization.

[0019] 3. In the present invention, the bubbles are divided into two groups by the stirring shaft. The large bubble group released by the aeration disc at the bottom can quickly rise to form a vertical gas cycle, driving the water body to convect up and down, while the fine bubbles discharged by the stirring shaft horizontally diffuse along the outer wall of the stirring shaft to form a horizontal gas coverage network, which not only expands the spatial distribution range of the bubbles in the water body, but also improves the oxygen mass transfer efficiency through the combination of bubbles with different particle sizes.

[0020] 4. In the present invention, by adjusting the outlet pressure of the air pump, the stirring plate expands outwards. During the operation of the equipment, the spatial cooperation between the stirring plate and the gas release port can not only prevent the bubbles from aggregating prematurely during the rising process, but also break the gas-liquid boundary layer through mechanical stirring, making the dissolved oxygen more evenly penetrate into each region of the water body.

Detailed implementation mode

[0032] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation mode of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0033] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation mode of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or selectively exclusive embodiment from other embodiments.

[0035] Embodiment 1 further illustrates an environmentally friendly and efficient sewage treatment aeration device proposed by the present invention, which includes an aeration tank 100. An aeration chamber 101 is formed inside the aeration tank 100. A stirring shaft 102 is rotatably connected inside the aeration tank 100. The stirring shaft 102 is arranged at one end of the aeration chamber 101 and fixedly connected with an aeration disc 103. A first air pump 104 is detachably installed on the upper end face of the aeration chamber 101. The air outlet end of the first air pump 104 is connected with a first rotating head 105. The first rotating head 105 is installed on the upper end face of the stirring shaft 102. An aeration mechanism 200 is arranged inside the aeration chamber 101. The aeration mechanism 200 includes a driving member 201 arranged on the upper end face of the aeration tank 100. An auxiliary member 202 is arranged inside the aeration chamber 101. A linkage member 203 is arranged on the stirring shaft 102. The auxiliary member 202 and the linkage member 203 cooperate with each other;

[0036] It can be seen from Figures 1 to 4 that the first air pump 104 forces high-pressure gas into the aeration, enabling the sewage in the chamber to come into contact with air for oxygenation. The stirring shaft 102 agitates the liquid, accelerating the transfer of oxygen in the air to the liquid, preventing the suspended objects in the pool from sinking, strengthening the contact between the organic matter, microorganisms and dissolved oxygen in the chamber, and oxidizing and decomposing the organic matter in the sewage;

[0037] It further includes an auxiliary mechanism 300. The auxiliary mechanism 300 includes a chemical dosing member 301 arranged inside the linkage member 203. A support member 302 is arranged on the linkage member 203. A rotating member 303 is arranged at the bottom end of the linkage member 203. A sliding member 304 is arranged at the bottom end of the support member 302. The sliding member 304 and the rotating member 303 cooperate with each other and are integrated inside the linkage member 203 through the chemical dosing member 301. Driven by the pressure difference, the liquid medicine uniformly oozes out through the liquid outlet holes 301f arrayed on the surface of the shaft body, and the instantaneous mixing of the medicine and the sewage is realized by means of the strong turbulent flow field formed by stirring, significantly improving the efficiency of chemical reactions such as flocculation and neutralization;

[0038] It further includes an adjustment mechanism 400. The adjustment mechanism 400 includes an annular member 401 arranged on the stirring shaft 102. An active member 402 is arranged inside the annular member 401. An adjustment member 403 is arranged inside the annular member 401. The active member 402 and the adjustment member 403 cooperate with each other;

[0039] Moreover, the internal structure of the stirring shaft 102 is further refined, and the bubbles are divided into two groups. The large bubble group released by the bottom aeration disc 103 can quickly rise to form a vertical gas circulation, driving the water body to convect up and down, while the fine bubbles discharged from the stirring shaft 102 horizontally diffuse along the outer wall of the stirring shaft 102 to form a horizontal gas coverage network;

[0040] Working principle: When in use, its air pump 104 forces high-pressure gas into the aeration disc 103, enabling the sewage in the chamber to come into contact with air for oxygenation. The stirring shaft 102 agitates the liquid, accelerating the transfer of oxygen in the air into the liquid, enhancing the contact between organic substances, microorganisms, and dissolved oxygen in the sewage, oxidizing and decomposing the organic substances in the sewage. At the same time, driven by the pressure difference, the liquid medicine seeps out evenly through the array of liquid outlet holes 301f on the surface of the shaft body, and the instantaneous mixing of the medicine and the sewage is achieved by means of the strong turbulent flow field formed by stirring, significantly improving the efficiency of chemical reactions such as flocculation and neutralization. Moreover, the stirring shaft 102 divides the bubbles into two groups. The large bubble group released by the bottom aeration disc 103 can quickly rise to form a vertical gas circulation, driving the water body to convect up and down, while the fine bubbles discharged by the stirring shaft 102 diffuse horizontally along the outer wall of the stirring shaft 102 to form a horizontal gas coverage network. This "vertical-horizontal" composite exhaust mode not only expands the spatial distribution range of bubbles in the water body but also improves the oxygen mass transfer efficiency through the combination of bubbles with different particle sizes.

[0041] Embodiment 2

[0042] On the basis of Embodiment 1, the following technical features are added: The aeration mechanism 200 includes a driving member 201 provided on the upper end face of the aeration tank 100, an auxiliary member 202 is arranged in the aeration chamber 101, a linkage member 203 is arranged on the stirring shaft 102, the auxiliary member 202 and the linkage member 203 cooperate with each other. The driving member 201 is fixedly installed on the mounting frame 201a on the upper end face of the aeration tank 100. A motor 201b is detachably installed in the mounting frame 201a. The rotor shaft end of the motor 201b is fixedly connected with a first gear 201c. A second gear 201d is fixedly connected to the outer wall of the stirring shaft 102. The first gear 201c meshes with the second gear 201d. The motor 201b is adjusted by an external controller. The motor 201b drives the first gear 201c to rotate. The first gear 201c meshes with the second gear 201d, thereby driving the internal stirring shaft 102 to rotate.

[0043] The auxiliary member 202 includes an annular groove 202a provided at the top of the aeration chamber 101. An annular plate 202b is fixedly connected in the annular groove 202a. A toothed ring 202c is fixedly connected to the inner wall of the annular plate 202b. The linkage member 203 includes a connecting plate 203a fixedly connected to the outer wall of the stirring shaft 102. Stirring rods 203b are rotatably connected to both sides of the connecting plate 203a through bearings. A stirring blade 203c is fixedly connected to the outer wall of the stirring shaft 102. A third gear 203d is fixedly connected to the outer wall of the stirring rod 203b. The third gear 203d meshes with the toothed ring 202c.

[0044] By Figures 1 to 5It can be seen that the annular plate 202b is fixedly connected to the top end of the inner wall of the aeration chamber 101. A toothed ring 202c is fixedly connected to the inner ring position of the annular plate 202b. A connecting plate 203a is fixedly connected to the outer wall of the stirring shaft 102. The stirring shaft 102 is rotatably connected inside the connecting plate 203a. A third gear 203d is fixedly connected to the stirring shaft 102. When the stirring shaft 102 rotates, it drives the connecting plate 203a to rotate simultaneously. While the connecting plate 203a rotates, the third gear 203d rotates synchronously;

[0045] The chemical dosing member 301 includes chemical dosing boxes 301a arranged on both sides of the connecting plate 203a. An air outlet pipe 301b is arranged on the side wall of the chemical dosing box 301a. A second rotary joint 301c is arranged on the air outlet pipe 301b. The second rotary joint 301c is arranged on the upper end surface of the stirring rod 203b. An activity cavity 301d is formed inside the stirring rod 203b. A plurality of liquid outlet holes 301f are arranged on the outer wall of the activity cavity 301d. Figures 2 to 6 It can be seen that an air pump and a liquid storage box are arranged inside the chemical dosing box 301a (not shown in the figure). Due to the pressure difference generated by the air pump, the liquid medicine enters the activity cavity 301d of the stirring rod 203b. One-way valves are installed in the liquid outlet holes 301f. In this way, the liquid medicine is discharged from the liquid outlet holes 301f on the stirring rod 203b;

[0046] In summary, in the chemical dosing link, the device integrates the chemical dosing member 301 into the inner cavity 401a of the stirring shaft 102. Driven by the pressure difference inside the chemical dosing box 301a, the liquid medicine uniformly seeps out through the array of liquid outlet holes 301f on the shaft surface, and instantaneous mixing of the medicine and the sewage is achieved by means of the strong turbulent flow field formed by stirring.

[0047] Working principle: As can be seen from Embodiment 1, during use, the external controller is used to adjust the motor 201b. The motor 201b drives the first gear 201c on the shaft to rotate. The first gear 201c meshes with the second gear 201d, thereby driving the internal stirring shaft 102 to rotate. When the stirring shaft 102 rotates, it drives the connecting plate 203a to rotate simultaneously. While the connecting plate 203a rotates, the third gear 203d rotates synchronously. Through the double-layer effect of the stirring shaft 102 and the stirring rod 203b, the transfer of oxygen in the air to the liquid is accelerated, the contact between the organic matter, microorganisms and dissolved oxygen in the chamber is strengthened, and the organic matter in the sewage is oxidized and decomposed. At the same time, driven by the pressure difference inside the chemical dosing box 301a, the liquid medicine uniformly seeps out through the array of liquid outlet holes 301f on the shaft surface, and instantaneous mixing of the medicine and the sewage is achieved by means of the strong turbulent flow field formed by stirring. This not only solves the problem of uneven mixing caused by a single chemical dosing point, but also enables the rapid dispersion of medicine molecules in the reaction system through hydrodynamic action, significantly improving the efficiency of chemical reactions such as flocculation and neutralization.

[0048] Embodiment Three

[0049] On the basis of Embodiment 2, the following technical features are added: It further includes an auxiliary mechanism 300. The auxiliary mechanism 300 includes a chemical addition member 301 provided in the linkage member 203. A support member 302 is provided on the linkage member 203. A rotating member 303 is provided at the bottom end of the linkage member 203. A sliding member 304 is provided at the bottom end of the support member 302. The sliding member 304 cooperates with the rotating member 303. The support member 302 includes a support plate 302a rotatably connected to the outer wall of the stirring shaft 102. Multiple groups of circular holes 302b are provided on both sides of the upper end surface of the support plate 302a. A rotating shaft 302c is rotatably connected in the circular hole 302b through a bearing. The rotating shaft 302c penetrates through both ends of the support plate 302a and is fixedly connected with a folding plate 302d. An arc-shaped groove 302e is provided on the outer wall of the rotating shaft 302c;

[0050] It can be seen from Figures 2 to 6 that on both sides of the support plate 302a, there is a structure of folding plates 302d arranged in multiple layers and staggered. When the bubble group on the aeration disc 103 rises, the folding plates 302d driven by the stirring shaft 102 generate a multi-stage cutting effect on the rising bubbles, breaking and cutting the bubble group, significantly increasing the gas-liquid interface area and prolonging the bubble residence time. At the same time, the turbulent vortices formed by the folding plates 302d can accelerate the liquid film renewal frequency, strengthening the diffusion mass transfer efficiency of oxygen molecules between the gas and liquid phases. Moreover, the combined movement of the radial flow and axial flow generated by the rotation of the stirring shaft 102 can effectively prevent the deposition of suspended matter and promote the full contact between microorganisms and the substrate;

[0051] The rotating member 303 includes a circular plate 303a fixedly connected to the bottom end of the stirring rod 203b. A limiting ring groove 303b is provided in the circular plate 303a. The limiting ring groove 303b is composed of a variable diameter part 303c and a transition part 303d. The sliding member 304 includes a chute one 304a provided on both sides of the bottom end of the support plate 302a. A slider 304b is slidably connected in the chute one 304a. A compression spring 304c is fixedly connected to the side wall of the slider 304b. The compression spring 304c is fixedly connected to the side wall of the chute. A sliding plate 304d is fixedly connected to the bottom end of the slider 304b. Multiple groups of positioning blocks 304e are fixedly connected to the upper end surface of the sliding plate 304d. The corresponding positioning blocks 304e are slidably connected in the arc-shaped groove 302e. A bending part 304f is formed at one end of the sliding plate 304d. A limiting rod 304g is fixedly connected to the upper end surface of the bending part 304f. The limiting rod 304g is slidably connected in the limiting ring groove 303b;

[0052] It can be seen from Figures 2 to 6It can be seen that a circular plate 303a is fixedly connected to the bottom end of the stirring rod 203b. The circular plate 303a is driven by the stirring rod 203b to rotate. Since the radius of the limiting ring groove 303b of the circular plate 303a is constantly changing, and a limiting rod 304g is slidably connected in the limiting ring groove 303b, the limiting rod 304g is fixedly connected with a bent portion 304f, and the bent portion 304f and the sliding plate 304d are integrally formed. When the circular plate 303a rotates, since the slider 304b on the bent portion 304f slides in the chute, the bent portion 304f and the sliding plate 304d perform a linear motion in the horizontal direction. Since the positioning block 304e is slidably connected in the arc-shaped groove 302e correspondingly, the folding plate 302d on the rotating shaft 302c is driven to rotate, thereby directionally shearing and breaking the bubbles;

[0053] In summary, by deeply integrating the stirring shaft 102 with the aeration mechanism 200 and the built-in dosing member 301, the present device uses the rotation of the stirring shaft 102 to drive the folding plate 302d to directionally shear and break the bubbles, synchronously enhancing the oxygen dissolution efficiency and the local turbulence intensity. It not only avoids the traditional aeration blind area, but also maintains the stable dispersion of the suspended matter through continuous agitation. At the same time, the dosing member 301 embedded in the stirring shaft 102 releases the medicament along the fluid movement trajectory. Under the synergistic action of mechanical stirring and bubble disturbance, rapid homogeneous mixing of the medicament and the sewage is achieved, forming an integration of aeration and oxygenation, anti-deposition strengthening, and precise dosing.

One end of the pushing spring 402b is fixedly connected to the outer wall of the auxiliary plate 401c, and the other end of the pushing spring 402b is fixedly connected to the outer wall of the movable plate 402a.

[0056] By Figures 7 to 10It can be known that a cylindrical cavity 401a is provided inside the stirring shaft 102. The cavity 401a is divided into multiple regions by an auxiliary plate 401c. An active plate 402a is connected to the auxiliary plate 401c through a compression spring 304c. To ensure the use effect, four groups of openings 401d are provided on the circular plate 303a. A movable rod 402c is fixedly connected to the corresponding position on the movable rod 402c. The movable rod 402c is correspondingly arranged in the opening 401d. When high-pressure gas enters the cavity 401a of the stirring shaft 102 from the second rotary joint 301c, the movable rod 402c in the opening 401d is thus squeezed. When the movable rod 402c is squeezed, it drives the active plate 402a on the movable rod 402c to slide on the support rod 401b. At this time, the compression spring 304c deforms, and the auxiliary block 402e on the active plate 402a moves synchronously. When the movable rod 402c disengages from the opening 401d, the opening 401d opens, and at this time, the gas jets out from the opening 401d;

[0057] The adjusting member 403 includes multiple groups of straight holes 403a symmetrically arranged on the outer wall of the support rod 401b. A straight plate 403b is symmetrically and slidably connected in a single straight hole 403a. One end of the straight plate 403b passing through the stirring shaft 102 is provided with a stirring plate 403c. Multiple groups of straight plates 403b are correspondingly arranged on the outer wall of the stirring plate 403c. A limiting portion 403d is integrally formed on the outer wall of the straight plate 403b. Multiple groups of air outlet holes 403e are provided on the outer wall of the stirring shaft 102. One-way valves are installed in the air outlet holes 403e. A positioning rod 403f is installed between adjacent straight plates 403b. The positioning rod 403f is correspondingly slidably connected in the second chute 402f;

[0058] The stirring plate 403c has an arc-shaped structure. When the stirring shaft 102 rotates, it drives the stirring plate 403c on its straight plate 403b to rotate synchronously. Since a positioning rod 403f is provided between adjacent straight plates 403b and the positioning rod 403f is correspondingly slidably connected in the second chute 402f, when the auxiliary block 402e on the active plate 402a moves synchronously, due to the deflection force of the second chute 402f, the straight plate 403b is driven to slide in the straight hole 403a. And a limiting portion 403d is integrally formed on the straight plate 403b, so as to limit the moving distance of the straight plate 403b;

[0059] Working principle: As can be seen from Embodiment 1, after the air pump injects gas into the hollow stirring shaft 102, the flow rate of the air outlet holes 403e on the stirring shaft 102 is limited, thus squeezing the movable rod 402c in the opening 401d. When the movable rod 402c is squeezed, it drives the movable plate 402a on the movable rod 402c to slide on the support rod 401b. At this time, the compression spring 304c deforms, and the auxiliary block 402e on the movable plate 402a moves synchronously. When the movable rod 402c disengages from the opening 401d, the opening 401d opens. At this time, the gas exits from the opening 401d. Due to the limited flow rate of the air outlet holes 403e, the gas then squeezes the next group of movable rods 402c until it enters the aeration disc 103. In this way, the gas is discharged in layers from the air outlet holes 403e distributed on the bottom aeration disc 103 and the shaft body. The large bubble group released by the bottom aeration disc 103 can quickly rise to form a gas circulation in the vertical direction, driving the up and down convection of the water body, while the fine bubbles discharged from the air outlet holes 403e on the shaft body horizontally diffuse along the outer wall of the stirring shaft 102 to form a horizontal gas coverage network. This "vertical-horizontal" composite exhaust mode not only expands the spatial distribution range of the bubbles in the water body, but also improves the oxygen mass transfer efficiency through the combination of bubbles with different particle sizes;

[0060] Moreover, the outlet pressure of the air pump can be adjusted, so that the stirring plate 403c expands outwards or retracts. During the operation of the equipment, the spatial cooperation between the stirring plate 403c and the gas release port can not only prevent the bubbles from aggregating prematurely during the rising process, but also break the gas-liquid boundary layer through mechanical agitation, making the dissolved oxygen penetrate more evenly into each area of the water body.

[0061] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
