A first driving wheel 11 is installed at the output end of the motor 10. The first driving wheel 11 is plugged into the power transmission mechanism.

[0026] Example 2

[0027] Reference Figure 1-6 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0028] The power transmission mechanism includes a pin rod 15, a second driving wheel 12, a first transmission wheel 13 and a second transmission wheel 14. The pin rod 15 is rotatably mounted on the cover body of the top cover 6. The second driving wheel 12 and the first transmission wheel 13 are both mounted on the rod body of the pin rod 15. The second transmission wheel 14 is mounted on the upper end of the rotating shaft 7. The second driving wheel 12 is meshed with the second transmission wheel 14, and the first driving wheel 11 is meshed with the first transmission wheel 13. The setting of the power transmission mechanism makes the first driving wheel 11 and the first transmission wheel 13 and the second driving wheel 12 and the second transmission wheel 14 form two groups of reduction transmissions, namely The motor 10 can drive the rotating shaft 7 to rotate more effortlessly through two sets of reduction transmission gears; a protective frame 16 is fixed to the upper surface of the top cover 6, and a lifting ring is provided at the upper end of the protective frame 16. The frame body of the protective frame 16 is connected to the rotating shaft 7 and the end of the upper end of the pin rod 15. The setting of the protective frame 16 not only improves the stability of the rotating shaft 7 and the pin rod 15, but also facilitates lifting; the rotating shaft 7 is rotatably installed on the rod body of the processing box 1, and the end of the stabilizing frame 17 away from the rotating shaft 7 abuts against the inner wall of the processing box 1.

[0030] Principle and advantages of use: During use of the utility model, the sludge inlet pipe 2, the reagent inlet pipe 3 and the discharge pipe 4 are respectively connected to corresponding facilities in the outside world, and valves are installed on the pipe bodies, that is, the sludge to be treated in the outside world enters the treatment box 1 through the sludge inlet pipe 2, and the reagent enters the treatment box 1 in the same way. Then the motor 10 drives the rotating shaft 7 to rotate through the power transmission mechanism, and the rotating shaft 7 drives the stirring rod 9 and the blades 8 to rotate, that is, at this time, the sludge and the reagent in the treatment box 1 are stirred and mixed by the stirring rod 9 and the blades 8, and the mixed materials are finally discharged from the discharge pipe 4 and enter the subsequent equipment for subsequent essence treatment.

[0031] In the above process, since the lower end of the rotating shaft 7 is the blade 9, when the rotating shaft 7 rotates, the blade 9 pushes the sludge to roll upward, so that the sludge provides a downward reaction force to the blade 9, that is, this reaction force drives the rotating shaft 7 to move downward through the blade 9, and finally pulls the top cover 6 to move downward through the rotating shaft 7, so that the top cover 6 and the treatment box 1 are more closely connected to prevent the stirred sludge and sewage from leaking from the gap between the two; and because the top cover 6 and the rotating shaft 7, the stirring rod 9, the blade 8 and the like are heavy, the weight of the top cover 6 in this component is affected The top cover 6, the rotating shaft 7, the power transmission mechanism, the blades 8 and the stirring rod 9 are combined into a complete module during use of the present invention, so that when personnel inspect and repair the components and bearings used for stirring inside the processing box 1, they can directly replace the above-mentioned modules, thereby effectively shortening the downtime. Moreover, through the setting of the limit rod 5, the top cover 6 can be directly lifted upwards to complete the disassembly, which saves the time for personnel to tighten the bolts, thereby further shortening the downtime of the device during maintenance, thereby improving the working efficiency of the device.

[0032] It should be further explained that the setting of the power transmission mechanism makes the first driving wheel 11 and the first transmission wheel 13 and the second driving wheel 12 and the second transmission wheel 14 form two sets of reduction transmission, that is, the motor 10 can drive the rotating shaft 7 to rotate more effortlessly through the two sets of reduction transmission gears; the setting of the protection frame 16 not only improves the stability of the rotating shaft 7 and the pin rod 15, but also facilitates lifting; the setting of the stabilizing frame 17 further improves the stability of the rotating shaft 7; the setting of the limiting protrusion 18 can limit the stabilizing frame 17, that is, the stabilizing frame 17 can have a more stable effect on the rotating shaft 7; the setting of the observation window 19 is convenient for personnel to observe the internal operation status of the processing box 1; the setting of the sealing ring is convenient to improve the sealing between the top cover 6 and the processing box 1.
