Description

Technical Field

[0001] This utility model relates to the field of aeration device technology, and in particular to an oxidation aeration device. Background Technology

[0002] An aeration device is a device or system used to forcibly inject air or oxygen into a liquid to increase the dissolved oxygen concentration, promote oxidation reactions, or mix water. It is one of the key devices in water treatment, sewage treatment, aquaculture, and industrial processes. An oxidation aeration device is a water treatment device that combines physical aeration and chemical-biological oxidation reactions. It is used to efficiently degrade organic pollutants in water, remove odors, kill pathogenic microorganisms, or transform harmful substances through the synergistic effect of forced oxygen supply and oxidation technology.

[0003] To address this, patent CN216038884U discloses an improved oxidation aeration device, comprising a housing and a vibration mechanism. A corrosion-resistant main pipe is located on one side of the housing, with corrosion-resistant horizontal pipes at both ends. Each horizontal pipe has a concentric reducer at its outer end, and each reducer has a corrosion-resistant branch pipe at its outer end. Each branch pipe has a second elbow at its outer end. Several branch joints are provided on the horizontal and branch pipes. Each branch joint and second elbow has an aeration pipe at its outer end. A reciprocating plate is located between the bottom surfaces of two branch pipes. The reciprocating plate is connected to the housing via the vibration mechanism. This invention solves the problem of poor desulfurization aeration through the coordinated use of various mechanisms. Furthermore, the overall structure is compact, and the reciprocating vibration of each pipe prevents blockage, further improving the aeration effect.

[0004] While the use of multi-stage aeration pipes in the above-mentioned process improves the uniformity of oxygen distribution, it makes it difficult to stir the liquid and oxygen, resulting in uneven gas-liquid mixing and reducing the residence time of bubbles in the liquid, thus reducing oxidation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an oxidation aeration device to solve the problem that existing oxidation aeration devices are not easy to stir.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an oxidation aeration device, including a box and a stirring structure;

[0007] A water inlet pipe is fixed to one side of the top of the tank, a water outlet pipe is fixed to one side of the bottom of the tank, and an aeration structure is installed at the bottom of the tank.

[0008] A stirring structure is fixed to the top of the box. The stirring structure includes a fixing block fixed to the top of the box. The fixing block has an internal groove. A rotating tube is installed inside the internal groove. A rotating ring is fixed to the outer side of the top of the rotating tube. A rotating groove is installed inside the fixing block outside the rotating ring. Connecting pipes are fixed to both sides of the rotating tube inside the box. An air outlet is fixed to the bottom side of the connecting pipe. An air inlet is installed on the outer side of the rotating tube inside the internal groove. A second air supply pipe is fixed to one side of the fixing block.

[0009] Preferably, the aeration structure includes a first aeration pipe installed inside the housing, with a first mounting block fixed at both ends of the first aeration pipe, a second aeration pipe fixed to one side of the first aeration pipe, a second mounting block fixed to one end of the second aeration pipe, an exhaust pipe fixed to the bottom side of the second aeration pipe, an aeration disc installed at the bottom end of the exhaust pipe, an oxygen pump fixed to one side of the housing, and a first air supply pipe fixed to one end of the oxygen pump.

[0010] Preferably, one side of the first mounting block is fixedly connected to both sides of the box body by bolts, and one side of the second mounting block is fixedly connected to one side of the box body by bolts.

[0011] With the above structure, the first aeration pipe and the second aeration pipe are fixed inside the box by the first mounting block and the second mounting block respectively during use, thereby ensuring stable support for the first aeration pipe and the second aeration pipe.

[0012] Preferably, the second aeration pipes are distributed at equal intervals on one side of the first aeration pipe, the first aeration pipe and the second aeration pipe are connected internally, the exhaust pipes are distributed at equal intervals on the bottom side of the second aeration pipe, one end of the first air supply pipe extends through one side of the bottom of the box to the inside of the box and is fixedly connected to one side of the first aeration pipe, and the inside of the first air supply pipe is connected to the inside of the first aeration pipe.

[0013] With the above structure, oxygen is evenly dispersed into the liquid inside the tank through the porous structure inside the aeration disc during use. This causes tiny bubbles to rise from the bottom of the tank, prolonging the residence time of the bubbles inside the tank and thus improving the oxidation efficiency.

[0014] Preferably, a motor is fixed to the top of one side of the housing of the fixing block, a first rotating shaft is fixed to the output end of the motor, a driving gear is fixed to the top of the first rotating shaft, a driven gear is installed on one side of the driving gear, and a second rotating shaft is fixed to the bottom of the driven gear.

[0015] Preferably, the rotating ring and the fixed block are rotatably connected by a rotating groove, and the bottom end of the rotating tube extends through the top of the box and into the interior of the box.

[0016] Preferably, the connecting pipes are distributed at equal intervals on both sides of the rotating pipe inside the housing, the interior of the rotating pipe is connected to the interior of the connecting pipe, and the air outlets are distributed at equal intervals on the bottom side of the connecting pipe.

[0017] With the above structure, during use, the rotating tube drives the connecting tube to rotate, which stirs the liquid inside the tank, thereby making the liquid and oxygen mix more thoroughly.

[0018] Preferably, the air inlets are evenly spaced on the outside of the rotating tube inside the built-in groove, one end of the second air supply pipe extends through one side of the fixing block into the inside of the built-in groove, and the other end of the second air supply pipe is fixedly connected to the output end of the oxygen pump.

[0019] With the above structure, during use, the second gas supply pipe can input oxygen into the interior of the gas outlet through the rotating pipe and connecting pipe, thereby ensuring thorough mixing of the liquid and oxygen during the stirring process, while preventing bubbles from rising too quickly, further extending the gas residence time, and thus improving the oxidation efficiency.

[0020] Preferably, the driving gear and the driven gear are meshed together, and the bottom end of the second rotating shaft extends through the top end of the fixed block into the interior of the built-in groove and is fixedly connected to the top end of the rotating tube.

[0021] The advantages of the oxidation aeration device provided by this utility model are as follows:

[0022] By setting up an aeration structure and starting the oxygen pump, oxygen enters the aeration disc through the exhaust pipe and is evenly dispersed into the liquid inside the tank through its porous structure, forming microbubbles. By setting up multiple sets of aeration discs, the gas-liquid contact area is increased, which allows the microbubbles to rise from the bottom of the tank, thereby prolonging the residence time inside the tank and improving the oxidation efficiency.

[0023] By incorporating a stirring structure, the rotating tube is driven by a motor to rotate the connecting tube, thus stirring the liquid inside the chamber. Simultaneously, oxygen is supplied into the rotating tube and connecting tube through a second gas supply pipe and output out through the gas outlet. This process ensures thorough mixing of the liquid and oxygen during stirring, while preventing bubbles from rising too quickly and further extending the gas residence time, thereby improving oxidation efficiency.

[0033] The first aeration pipe 401 and the second aeration pipe 403 are fixed inside the housing 1 by the first mounting block 402 and the second mounting block 404 respectively, ensuring stable support. Then, by starting the oxygen pump 407, oxygen is delivered to the inside of the first aeration pipe 401 and the second aeration pipe 403 through the first air supply pipe 408, and then enters the aeration disc 406 through the exhaust pipe 405. The aeration disc 406 is made of microporous ceramic or rubber diaphragm to ensure that the bubbles are small and uniform, so that the microbubbles rise from the bottom of the housing 1, prolonging the residence time of the bubbles inside the housing 1, thereby improving the oxidation efficiency.

[0034] Reference Figures 1-4As shown, a stirring structure 5 is fixed to the top of the housing 1. The stirring structure 5 includes a fixing block 501 fixed to the top of the housing 1. An internal groove 502 is provided inside the fixing block 501. A rotating tube 503 is provided inside the internal groove 502. A rotating ring 504 is fixed to the outer side of the top of the rotating tube 503. A rotating groove 505 is provided inside the fixing block 501 outside the rotating ring 504.

[0035] The motor 510 drives the first rotating shaft 511 to rotate, which in turn drives the second rotating shaft 514 to rotate under the drive of the driving gear 512 and the driven gear 513. This causes the rotating tube 503 to rotate, which in turn causes the connecting tube 506 to rotate, stirring the liquid inside the housing 1. At the same time, oxygen is delivered into the interior tank 502 through the second gas supply tube 509 and input into the rotating tube 503 and the connecting tube 506 through the air inlet 508. It is then output outward through the air outlet 507. This process ensures that the liquid and oxygen are fully mixed during the stirring process, while preventing bubbles from rising too quickly and further extending the gas residence time, thereby improving the oxidation efficiency.
