[0026] The stirring shaft 7 and the first stirring blades 8 promote the mixing of waste liquid and chemical reagents through mechanical stirring, and the annular sleeve 18 and the second stirring blades 19 add additional dynamic mixing elements based on the stirring shaft 7 to further improve the mixing effect.
[0027] Further, the top center of the bucket cover 2 is fixedly connected with a mounting shell 9, the upper end of the stirring shaft 7 extends into the mounting shell 9 and is rotatably connected thereto, the front surface of the mounting shell 9 is fixedly connected with a controller 20 that controls the entire device, and a transparent observation window 22 is embedded in the front surface of the waste liquid treatment bucket 1.
[0028] The mounting shell 9 is located at the top center of the bucket cover 2 and is used to fix the upper end of the stirring shaft 7, ensuring that it can rotate freely. The mounting shell 9 not only provides mechanical support but also protects the internal rotating connection components from the external environment. The controller 20 is fixed on the front surface of the mounting shell 9 to control the operation of the entire device, and the transparent observation window 22 is embedded in the front surface of the waste liquid treatment bucket 1, allowing the operator to directly observe the state of the waste liquid in the bucket, such as the mixing condition and liquid level, which is very helpful for timely discovering problems or making necessary adjustments.

[0032] The design of the first bevel gear 10 and the second bevel gear 11 realizes the conversion of the direction of power, and the first bevel gear 10 on the stirring shaft 7 is meshingly connected with the second bevel gear 11, so that the originally horizontal power can be converted into vertical rotary force, driving the stirring shaft 7 and the first stirring blade 8 and the second stirring blade 19 thereon to rotate, thereby realizing the mixing of waste liquid and chemical reagents. The power motor 12 provides the required driving force, which is transmitted to the stirring shaft 7 through the first bevel gear 10 and the second bevel gear 11, thereby driving the first stirring blade 8 and the second stirring blade 19 to rotate.
[0033] Further, the third bevel gear 13 is meshingly connected on the top side of the second bevel gear 11, the third bevel gear 13 is located above the first bevel gear 10, the vertical threaded rod 14 is fixedly connected on the inner wall of the third bevel gear 13, and the top of the vertical threaded rod 14 is rotatably connected with the top of the inner wall of the installation shell 9.
[0034] Through this design, power can be transmitted from the horizontal power motor 12 to the third bevel gear 13 and to the vertical threaded rod 14. The vertical threaded rod 14 is not only rotatably connected between the top of the installation shell 9 and the top of the inner wall of the installation shell 9, but also extends to the inside of the stirring shaft 7 and is rotatably connected therewith. This means that the vertical threaded rod 14 can rotate while allowing the stirring shaft 7 to perform independent rotation operations.
[0035] Further, the vertical threaded rod 14 extends to the inside of the stirring shaft 7 below and is rotatably connected therewith, and the lifting threaded sleeve 15 is threadedly connected on the lower surface of the vertical threaded rod 14 inside the stirring shaft 7, and the lifting threaded sleeve 15 extends to the outside of the bottom of the stirring shaft 7 below and is slidably connected therewith.
[0036] When the vertical threaded rod 14 rotates, due to the action of the thread, the lifting threaded sleeve 15 will move up and down along the vertical threaded rod 14, and the lifting threaded sleeve 15 extends to the outside of the bottom of the stirring shaft 7 below and is slidably connected therewith, which enables it to drive the components connected thereto, such as the annular sleeve 18 and the second stirring blade 19, to move up and down.
[0037] Further, the inner wall of the stirring shaft 7 is fixedly connected with a sealing ring 17, the inner wall of the sealing ring 17 is slidably connected with the surface of the lifting threaded sleeve 15, the vertical lifting limiting rod 16 is fixedly connected between the top and bottom of the inner wall of the stirring shaft 7, and the lifting limiting rod 16 is slidably connected between the lifting threaded sleeve 15.
[0038] The main function of the sealing ring 17 is to prevent the waste liquid from penetrating into the stirring shaft 7, and to ensure that the lifting threaded sleeve 15 can smoothly slide in a sealed state. The function of the lifting limiting rod 16 is to limit the up and down movement range of the lifting threaded sleeve 15, to avoid exceeding the predetermined stroke, and to provide guidance for the lifting threaded sleeve 15, to ensure the stability of the movement track.
[0039] Further, the surface of one end of the lifting threaded sleeve 15 located below the bottom of the stirring shaft 7 is fixedly sleeved with an annular sleeve 18, and a plurality of groups of second stirring blades 19 are arranged in a circumferential array on the surface of the annular sleeve 18.
[0040] The annular sleeve 18 and the second stirring blades 19 are located on the surface of one end of the lifting threaded sleeve 15 below the bottom of the stirring shaft 7, and are fixedly sleeved on the lifting threaded sleeve 15. With the up and down movement of the lifting threaded sleeve 15, the annular sleeve 18 and the second stirring blades 19 thereon will also move, realizing the stirring action in the up and down direction.
[0041] Firstly, the waste liquid to be treated and the necessary chemical reagents are added into the waste liquid treatment barrel 1 through the liquid injection hopper 3. The operator can monitor the state of the waste liquid through the transparent observation window 22. The controller 20 is turned on, the power motor 12 installed in the mounting shell 9 is started, and the output shaft of the power motor 12 drives the second bevel gear 11 to rotate.
[0042] The power is transmitted from the second bevel gear 11 to the first bevel gear 10, and then drives the stirring shaft 7 and the first stirring blades 8 thereon to rotate, starting the preliminary rotary stirring of the waste liquid; at the same time, the power is also transmitted to the vertical threaded rod 14 through the third bevel gear 13, so that the vertical threaded rod 14 rotates. When the vertical threaded rod 14 rotates, the lifting threaded sleeve 15 moves up and down along the vertical threaded rod 14 due to the threaded connection between the vertical threaded rod 14 and the lifting threaded sleeve 15. The annular sleeve 18 and the second stirring blades 19 fixedly sleeved on the bottom of the lifting threaded sleeve 15 move up and down, increasing the longitudinal mixing action on the basis of the original rotary stirring, and the sealing ring 17 ensures that the lifting threaded sleeve 15 smoothly slides in the stirring shaft 7 while preventing the waste liquid from penetrating into the stirring shaft 7. The lifting limiting rod 16 limits the up and down movement range of the lifting threaded sleeve 15 and provides a guiding effect for the lifting threaded sleeve 15, ensuring the stability of the movement track. When the waste liquid treatment is completed, the liquid outlet pipe 4 is opened to discharge the treated liquid.
[0043] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
