[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a multi-stage spiral mixer for oil well cement additives includes a main support frame 1. A mixing mechanism 3 is provided at the upper end of the main support frame 1. The mixing mechanism 3 includes a fixed frame 31 fixedly connected to the upper end of the main support frame 1. A guide shaft 32 is movably connected to the inner side of the fixed frame 31. A rotating frame 33 is fixedly connected to one end of the guide shaft 32. A protective ring 34 is placed inside the rotating frame 33. A mixing chamber 35 is placed inside the protective ring 34. A cover plate 36 is placed on the outer side of the mixing chamber 35 near the upper side of the protective ring 34. A spiral frame 37 is movably connected to the inner side of the mixing chamber 35. A rotating shaft 38 is fixedly connected to the inner side of the spiral frame 37. An upper baffle 39 is fixedly connected to the upper side of the outer surface of the spiral frame 37. A lower baffle 310 is fixedly connected to the lower side of the outer surface of the spiral frame 37. A positioning rod 311 is fixedly connected to the lower end of the mixing chamber 35.

[0021] In this embodiment, a mounting base 312 is fixedly connected to the upper end of the cover plate 36, a small motor 313 is fixedly connected to one end of the mounting base 312, a limiting plate 314 is fixedly connected to one end of the cover plate 36, and a bolt 315 is threaded into the limiting plate 314. A main drive unit 316 is installed on the outer side of the guide shaft 32 near the fixing frame 31, a connecting shaft 317 is installed on the inner side of the main drive unit 316 near the lower side of the guide shaft 32, and a secondary drive unit 318 is installed on the outer side of the connecting shaft 317 near the main drive unit 316. A support member 319 is movably connected to the outer side of the drive shaft 317 near the auxiliary drive unit 318. A large motor 320 is installed at one end of the auxiliary drive unit 318. The rotating shaft 38 passes through the interior of the cover plate 36 and is movably connected to the cover plate 36. The upper end of the rotating shaft 38 is installed at the lower end of the small motor 313. The positioning rod 311 passes through the interior of the rotating frame 33 and is movably connected to the rotating frame 33. The bolt 315 extends into the interior of the rotating frame 33 and is threadedly connected to the rotating frame 33.

[0022] Specifically, by simultaneously activating the small motor 313 and the large motor 320, the small motor 313 drives the rotating shaft 38 to rotate, which in turn drives the screw carrier 37 to rotate. This causes the upper and lower baffles 39 and 310 to rotate along with the screw carrier 37, thus allowing the screw carrier 37 to mix the various raw materials in the mixing chamber 35. The upper and lower baffles 39 and 310 also turbulent the raw materials around the screw carrier 37, accelerating their flow. Simultaneously, the large motor 320 drives the auxiliary drive unit 318 to rotate, which in turn drives the main drive unit 316 via the connecting shaft 317. This main drive unit 316 then drives the guide shaft 32 to rotate, which in turn drives the rotating frame 33 to rotate. This, in turn, causes the rotating frame 33 to rotate the mixing chamber. The mixing chamber 35 rotates, causing the various raw materials inside to flip up and down, thus flipping the raw materials at the bottom of the mixing chamber 35 to the top. This, combined with the mixing of the screw frame 37, allows the raw materials in the mixing chamber 35 to be fully mixed in multiple stages. The rotating shaft 38 drives the screw frame 37 to rotate, and the upper baffle 39 and lower baffle 310 follow the rotation of the screw frame 37. At the same time, the guide shaft 32 drives the rotating frame 33 to rotate, which in turn drives the mixing chamber 35 to rotate. This achieves the purpose of flipping the raw materials at the bottom of the mixing chamber 35 to the top when the screw frame 37 drives the upper baffle 39 and lower baffle 310 to mix the raw materials in the mixing chamber 35, allowing the raw materials in the mixing chamber 35 to be fully mixed in multiple stages.

[0023] In this embodiment, a base 2 is fixedly connected to the lower end of the main support frame 1, and a secondary support frame 4 is fixedly connected to the upper end of the base 2 near the side of the main support frame 1. The front end of the secondary support frame 4 is fixedly connected to the rear end of the support member 319, and the upper end of the base 2 near the rear side of the secondary support frame 4 is fixedly connected to the lower end of the large motor 320.

[0024] Specifically, first tighten bolt 315 and remove cover plate 36, then remove mixing chamber 35 and pour various raw materials into mixing chamber 35, then put protective ring 34 on the outside of mixing chamber 35, then place mixing chamber 35 into rotating frame 33, and insert positioning rod 311 into rotating frame 33, then cover the outside of mixing chamber 35 with cover plate 36, and then tighten bolt 315 from inside limiting plate 314 into rotating frame 33, thus completing the preparation of mixing raw materials.

[0025] Working principle:

[0026] In use, the worker first tightens bolt 315, removes cover plate 36, then removes mixing chamber 35, pours various raw materials into mixing chamber 35, then puts protective ring 34 on the outside of mixing chamber 35, places mixing chamber 35 into rotating frame 33, inserts positioning rod 311 into rotating frame 33, then covers the outside of mixing chamber 35 with cover plate 36, and then tightens bolt 315 from inside limiting plate 314 into rotating frame 33, and then simultaneously starts small motor 3. 13. The large motor 320 causes the small motor 313 to drive the rotating shaft 38 to rotate, which in turn causes the rotating shaft 38 to drive the screw frame 37 to rotate. This causes the upper baffle 39 and the lower baffle 310 to rotate with the screw frame 37, thus allowing the screw frame 37 to mix the various raw materials in the mixing chamber 35. The upper baffle 39 and the lower baffle 310 also cause the raw materials around the screw frame 37 to be turbulent, thereby accelerating the flow of the raw materials. At the same time, the large motor 320 drives the auxiliary drive unit 318 to rotate, and the auxiliary drive unit 318 also rotates. The drive unit 318 drives the main drive unit 316 to rotate via the linkage shaft 317, which in turn drives the guide shaft 32 to rotate. The guide shaft 32 then drives the rotating frame 33 to rotate, which in turn drives the mixing chamber 35 to rotate. This causes the various raw materials inside the mixing chamber 35 to flip up and down, so that the raw materials at the bottom of the inner side of the mixing chamber 35 are flipped up. This, combined with the mixing of the screw frame 37, allows the raw materials in the mixing chamber 35 to be fully mixed in multiple stages. The rotating shaft 38 drives the screw frame 37 to rotate, and the upper and lower baffles 310 follow the rotation of the screw frame 37. At the same time, the guide shaft 32 drives the rotating frame 33 to rotate, which in turn drives the mixing chamber 35 to rotate. This achieves the purpose of flipping the raw materials at the bottom of the inner side of the mixing chamber 35 to the top when the screw frame 37 drives the upper and lower baffles 310 to mix the raw materials in the mixing chamber 35, thus allowing the raw materials in the mixing chamber 35 to be fully mixed in multiple stages.
