Description

Technical Field

[0001] This utility model relates to the field of aeration technology for high-salinity wastewater, specifically to an aeration device for treating high-salinity wastewater. Background Technology

[0002] High-salinity wastewater refers to wastewater with a total salt content of at least 1% by mass. It mainly originates from chemical plants and the extraction and processing of oil and natural gas. This type of wastewater contains various substances (including salt, oil, organic heavy metals, and radioactive materials). The sources of saline wastewater are widespread, and its volume is increasing year by year. Removing organic pollutants from saline wastewater is crucial to mitigating its environmental impact. Generally, the treatment of high-salinity wastewater involves aeration. Aeration refers to the forced introduction of air into the wastewater using specific methods and equipment. This allows the wastewater to come into contact with air, oxygenating it and agitating the liquid. This accelerates the transfer of oxygen from the air to the liquid, prevents suspended solids from settling, and enhances the contact between organic matter, microorganisms, and dissolved oxygen, thus oxidizing and decomposing the organic matter in the wastewater. This process of forced oxygenation into wastewater is called aeration.

[0003] Patent document CN222064281U discloses a wastewater aeration device, including a wastewater tank, an installation plate on the inner side of the wastewater tank, a pump body on the installation plate, a connecting pipe on one side of the pump body, a circulation pipe at the bottom of the connecting pipe, an air inlet pipe on one side of the connecting pipe, a first control valve at the connection between the air outlet pipe and the connecting pipe, a second control valve on the connecting pipe near the circulation pipe, an air outlet pipe on the inner side of the circulation pipe, and a nozzle assembly for automatic opening and closing on the air outlet pipe. In implementing this technical solution, the inventors discovered at least the following problems in the prior art: In actual use, the above-mentioned device only exhausts gas into the wastewater through nozzles, which has a poor agitation effect on the wastewater and insufficient contact between the wastewater and oxygen, resulting in low aeration efficiency, requiring more time and having poor performance.

Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An aeration device for treating high-salinity wastewater includes a wastewater tank, a movable seat slidably disposed on the top of the wastewater tank, and an agitator disposed at the bottom of the movable seat; The wastewater tank has movable blocks slidably installed on both sides of the top, and the top of a pair of movable blocks is fixedly connected to the bottom sides of the movable base.

[0007] Furthermore: the stirring assembly includes a hollow tube rotatably disposed on the inner wall of the movable seat, a plurality of stirring blades fixedly connected to the outer side of the hollow tube, a rotating disk fixedly connected to the bottom of the hollow tube, an air inlet pipe inserted and installed inside the hollow tube, the bottom end of the air inlet pipe communicating with the top of the rotating disk, and a plurality of exhaust pipes communicating with the top of the rotating disk.

[0008] Furthermore: a first motor is fixedly connected to the top of the movable seat, and a drive gear is fixedly connected to the output end of the first motor.

[0009] Furthermore, a driven gear is fixedly connected to the outside of the hollow tube, and the outside of the driving gear meshes with the outside of the driven gear.

[0010] Furthermore: a pair of springs are fixedly installed inside the exhaust pipe, a sealing plate is fixedly connected to the top of the springs, a sealing ring is fixedly connected to the bottom of the sealing plate, a sealing groove matching the sealing ring is opened at the top of the exhaust pipe, and multiple exhaust holes are opened on the outside of the sealing ring.

[0011] Furthermore: A pair of second motors are fixedly connected to one side of the wastewater pool, and a lead screw is fixedly connected to the output end of the second motor. The outer side of the lead screw is threadedly connected to the inner wall of the moving block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: After high-salt wastewater is injected into the wastewater tank, an external blower is connected to the air inlet pipe to deliver outside air to the rotating disc. The air is then discharged through multiple exhaust pipes on the top of the rotating disc, allowing the wastewater to come into contact with the air. The hollow tube drives the stirring blades and the rotating disc to rotate, agitating the wastewater and ensuring more thorough contact between the wastewater and oxygen. This effectively improves aeration efficiency and reduces the reaction time.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0021] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation 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 a single or selective embodiment that excludes other embodiments.

[0022] Please see Figures 1-4 As shown in the figure, an aeration device for treating high-salt wastewater provided in this embodiment of the present invention includes a wastewater tank 1, a movable seat 2 slidably disposed on the top of the wastewater tank 1, and an agitator 3 disposed at the bottom of the movable seat 2. The wastewater tank 1 has movable blocks 4 slidably installed on both sides of the top, and the top of a pair of movable blocks 4 is fixedly connected to the bottom sides of the movable base 2.

[0023] The stirring assembly 3 includes a hollow tube 31 rotatably disposed on the inner wall of the movable seat 2, a number of stirring blades 32 fixedly connected to the outside of the hollow tube 31, a rotating disk 33 fixedly connected to the bottom of the hollow tube 31, an air inlet pipe 34 inserted and installed inside the hollow tube 31, the bottom end of the air inlet pipe 34 communicating with the top of the rotating disk 33, and a number of exhaust pipes 35 communicating with the top of the rotating disk 33.

[0024] After high-salt wastewater is injected into wastewater tank 1, an external blower is connected to the air inlet pipe 34 to deliver outside air to the rotating disk 33. The air is then discharged through multiple exhaust pipes 35 on the top of the rotating disk 33, allowing the wastewater to come into contact with the air. The hollow tube 31 drives the stirring blades 32 and the rotating disk 33 to rotate, agitating the wastewater and ensuring more thorough contact between the wastewater and oxygen. This effectively improves aeration efficiency and reduces the reaction time. At the same time, the movable seat 2 drives the hollow tube 31 and the rotating disk 33 to move back and forth in the wastewater tank 1, ensuring full contact between the air and the wastewater in the wastewater tank 1, improving aeration efficiency, and making aeration more uniform and faster.

[0025] Preferably, a first motor 5 is fixedly connected to the top of the movable base 2, and a drive gear 6 is fixedly connected to the output end of the first motor 5.

[0026] A driven gear 7 is fixedly connected to the outside of the hollow tube 31, and the outside of the driving gear 6 meshes with the outside of the driven gear 7.

[0027] The first motor 5 drives the drive gear 6 to rotate, which in turn drives the hollow tube 31 to rotate via the driven gear 7.

[0028] Preferably, a pair of springs 8 are fixedly installed inside the exhaust pipe 35. A sealing plate 9 is fixedly connected to the top of the springs 8, and a sealing ring 10 is fixedly connected to the bottom of the sealing plate 9. A sealing groove 11 matching the sealing ring 10 is opened at the top of the exhaust pipe 35, and multiple exhaust holes 12 are opened on the outside of the sealing ring 10.

[0029] When the exhaust pipe 35 exhausts gas, the pressure generated pushes up the sealing plate 9 and stretches the spring 8. When the sealing plate 9 is pushed up, the sealing ring 10 separates from the sealing groove 11, exposing the multiple exhaust holes 12 inside the sealing ring 10. This allows the gas discharged from the exhaust pipe 35 to be discharged into the wastewater through the exhaust holes 12. When the exhaust stops, the sealing plate 9 loses pressure and, under the elastic force of the spring 8, returns to its initial position, sealing the top of the exhaust pipe 35. At the same time, the sealing ring 10 seals the sealing groove 11, thereby preventing sediment in the wastewater from clogging the exhaust pipe 35.

[0030] Preferably, a pair of second motors 13 are fixedly connected to one side of the wastewater tank 1, and a lead screw 14 is fixedly connected to the output end of the second motor 13. The outer side of the lead screw 14 is threadedly connected to the inner wall of the moving block 4.

[0031] The second motor 13 drives the lead screw 14 to rotate, causing the moving block 4 to move the moving seat 2 on the top of the wastewater pool 1.

[0032] The working principle of this utility model is as follows: After high-salt wastewater is injected into the wastewater tank 1, an external fan is connected to the air inlet pipe 34 to transport outside air to the rotating disk 33 through the air inlet pipe 34. The air is then discharged through multiple exhaust pipes 35 at the top of the rotating disk 33, allowing the wastewater to come into contact with the air. The hollow tube 31 drives the stirring blades 32 and the rotating disk 33 to rotate, stirring the wastewater and making the contact between the wastewater and oxygen more sufficient. This can effectively improve the aeration efficiency and reduce the reaction time. At the same time, the moving seat 2 drives the hollow tube 31 and the rotating disk 33 to move back and forth in the wastewater tank 1, so that the air and the wastewater in the wastewater tank 1 can come into full contact, improving the aeration efficiency and making the aeration more uniform and faster.

[0033] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
