When the double-curved-surface stirring wheel is replaced, the second toothed bars on the two sides are pressed at the same time, the second toothed bars drive the first toothed bars to move out of the clamping grooves through the gears, then the double-curved-surface stirring wheel can be detached, then the double-curved-surface stirring wheel needing to be installed is taken out, the double-curved-surface stirring wheel drives the second connecting frame to enter the first connecting frame, and the double-curved-surface stirring wheel is replaced. When the second connecting frame abuts against the curved surface of the first toothed bar, the first toothed bar overcomes the elastic force of the spring to retract into the spring groove, and when the clamping groove is aligned with the spring groove, the spring pushes the first toothed bar to be inserted into the clamping groove, and then installation of the double-curved-surface stirring wheel can be completed. The double-curved-surface stirring wheel can be quickly disassembled or assembled, and the disassembling and assembling efficiency of the double-curved-surface stirring wheel is improved.

Description

[0002] Hyperbolic mixer is a new type of equipment for urban sewage treatment, industrial wastewater treatment and water purification engineering technology.

[0003] The current hyperbolic sewage treatment mixer, for example, the hyperbolic sewage treatment mixer proposed in Publication No. CN219784399U, is provided with a mounting frame, a stirring motor, a rotating shaft and a hyperbolic stirring wheel. The upper end of the hyperbolic stirring wheel is in contact with the lower side of the fixed seat at the lower end of the rotating shaft, and the two are relatively connected by matching and plugging the plug-in studs and the sleeve holes, and then the locking nut is screwed on the outer side of the upper end of the plug-in stud to achieve a further stable connection between the fixed seat and the hyperbolic stirring wheel, and then the annular protective shell cover is sleeved on the outer side of the multiple plug-in studs through the threaded connection of the connecting screw ring and the annular protective shell, and when connecting, the anti-slip plate is raised, and then the push rod is cooperated to drive the limit cover to move up to avoid the cover blocking the installation of the annular protective shell, and the anti-slip plate is loosened after installation, and the push spring pushes the limit cover down, so that the limit cover is inserted outside the locking nut, which can achieve a stable limit on the locking nut, ensure the structural stability, and make the installation of the hyperbolic stirring wheel more stable.

[0004] When the existing hyperbolic sewage treatment mixer is in use, although it can achieve stable limiting of the locking nut and ensure the stability of the structure, making the installation of the hyperbolic stirring wheel more stable, it is found during use that the hyperbolic stirring wheel is not only installed by bolts, but also has a loosening structure. When the hyperbolic stirring wheel needs to be replaced, it is time-consuming and laborious, and the hyperbolic stirring wheel cannot be disassembled and assembled quickly, making it inconvenient to use.

[0025] When the hyperbolic stirring wheel 8 needs to be replaced, the second gear rods 17 on both sides are pressed at the same time. The second gear rods 17 drive the first gear rod 15 to move in the opposite direction through the gear 18, so that the first gear rod 15 moves out of the slot 13, and the disassembly of the hyperbolic stirring wheel 8 is completed. Then, the hyperbolic stirring wheel 8 to be installed is taken out, and the hyperbolic stirring wheel 8 drives the second connecting frame 10 to enter the first connecting frame 9. The bottom of the first gear rod 15 away from the spring 14 is a curved surface. When the second connecting frame 10 is against the curved surface of the first gear rod 15, the first gear rod 15 overcomes the elastic force of the spring 14 and retracts into the spring groove 12. When the slot 13 is aligned with the spring slot 12, the spring 14 pushes the first gear rod 15 to insert into the slot 13, so that the first connecting frame 9 and the second connecting frame 10 can be fixedly connected, thereby completing the installation of the hyperbolic stirring wheel 8.

After the hyperbolic stirring wheel 8 is installed, the openings of the connecting groove 11 and the gear rod groove 16 are sealed by two sealing rings 19 to prevent sewage from entering the installation structure of the hyperbolic stirring wheel 8.

[0028] Working principle: When the hyperbolic stirring wheel 8 needs to be replaced, the second gear rods 17 on both sides are pressed at the same time. The second gear rods 17 drive the first gear rods 15 to move in the opposite direction through the gear 18, so that the first gear rods 15 are moved out of the slot 13, and the disassembly of the hyperbolic stirring wheel 8 is completed. Then, the hyperbolic stirring wheel 8 to be installed is taken out, and the hyperbolic stirring wheel 8 drives the second connecting frame 10 to enter the first connecting frame 9. The bottom of the first gear rod 15 away from the spring 14 is a curved surface. When the second connecting frame 10 is against the curved surface of the first gear rod 15, the first gear rod 15 overcomes the elastic force of the spring 14 and retracts into the spring slot 12. When the slot 13 is aligned with the spring slot 12, the spring 14 pushes the first gear rod 15 to insert into the slot 13, so that the first connecting frame 9 and the second connecting frame 10 are fixedly connected, thereby completing the hyperbolic The installation of the hyperbolic stirring wheel 8 can be achieved through the installation mechanism of the hyperbolic stirring wheel 8, so that the disassembly or installation efficiency of the hyperbolic stirring wheel 8 is improved. When the height of the hyperbolic stirring wheel 8 needs to be adjusted according to the depth of sewage, the fastening screw 7 is loosened to allow the telescopic rod 6 to move in the telescopic groove 5. The distance between the first rotating shaft 3 and the second rotating shaft 4 is adjusted by the telescopic rod 6 and the telescopic groove 5, and then the height of the hyperbolic stirring wheel 8 is adjusted. After the adjustment is completed, the fastening screw 7 is tightened to fix the height of the hyperbolic stirring wheel 8. Through the telescopic mechanism, it is convenient to adjust the height of the hyperbolic stirring wheel 8 according to the depth of sewage. After the hyperbolic stirring wheel 8 is installed, the openings of the connecting groove 11 and the gear rod groove 16 are sealed by two sealing rings 19 to prevent sewage from entering the installation structure of the hyperbolic stirring wheel 8.
