[0002] In chemical production processes, it is often necessary to mix multiple raw materials in a stirring device to induce a chemical reaction. The stirring device typically includes a mixing tank and a rotating rod. The rotating rod is equipped with stirring blades that extend into the mixing tank. As the rotating rod rotates, it drives the stirring blades to agitate the raw materials, thereby achieving the purpose of mixing and inducing a chemical reaction.

[0003] In existing mixing devices, the structure of the mixing blades is fixed and the angle is not adjustable, making it difficult to adapt to the mixing needs of materials with different viscosities and ratios. This can easily lead to dead zones in the mixing process, resulting in uneven mixing.

[0004] In addition, in existing stirring devices, additives are often injected directly through a single pipe, which can easily lead to excessively high local concentrations, affecting reaction efficiency and product purity. Utility Model Content

[0030] See attached document Figure 1 -Appendix Figure 7 The present invention provides a chemical production mixing device, including a mixing tank 1, wherein the mixing tank 1 is provided with a multi-functional mixing mechanism;

[0031] The multifunctional stirring mechanism includes a rotating rod 7, which is located inside the stirring tank 1 and connected to the stirring tank 1 via a bearing. An inner groove 8 is formed inside the rotating rod 7, and a toothed plate 10 is fixedly installed inside the inner groove 8. Multiple connecting rods 11 are connected to both sides of the rotating rod 7 via bearings, and adjacent connecting rods 11 are connected by bearings. A connecting block 27 is fixedly connected to one end of each connecting rod 11, and a movable blade 13 is fixedly installed on one side of the connecting block 27. A protective cover 4 is fixedly installed on the top of the stirring tank 1, and an inner plate 14 is fixedly installed inside the protective cover 4. One end of the rotating rod 7 is connected to the inner plate 14 via a bearing. The inner plate 14 is connected to a hydraulic push rod 15 installed on one side. The output end of the hydraulic push rod 15 extends into the inner groove 8 and is connected to the toothed plate 10 through a bearing. A first gear 12 is fixedly sleeved on the outside of the connecting rod 11. The first gear 12 meshes with the toothed plate 10. A motor 16 is fixedly installed on the top of the inner plate 14. A drive shaft 17 is fixedly connected to the output end of the motor 16. One end of the drive shaft 17 is connected to the top of the mixing tank 1 through a bearing. A second gear 18 is fixedly sleeved on the outside of the drive shaft 17. A third gear 25 is fixedly sleeved on the outside of the rotating rod 7. The third gear 25 meshes with the second gear 18.

[0032] In this embodiment, during the stirring process, the stirring effect can be optimized by adjusting the angle of the movable blades 13 according to the viscosity, proportion, and other characteristics of the chemical raw materials. Activating the hydraulic push rod 15 causes its output end to push or pull the toothed plate 10 within the inner groove 8. Because the toothed plate 10 meshes with the first gear 12, the movement of the toothed plate 10 drives the first gear 12 to rotate. The first gear 12 is fixedly sleeved on the outside of the connecting rod 11, so the rotation of the first gear 12 drives the connecting rod 11 to rotate. One end of the connecting rod 11 is fixedly connected to the movable blades 13 via a connecting block 27. The rotation of the connecting rod 11 drives the connecting block 27 to rotate, thereby causing the movable blades 13 to rotate. This allows control of the stirring angle of multiple movable blades 13. By adjusting the angle of the movable blades 13, the stirring requirements of different materials can be adapted, the stirring range expanded, dead zones eliminated, and the mixing uniformity improved.

[0033] To achieve the purpose of material distribution, this device adopts the following technical solution: The multi-functional stirring mechanism also includes a material distribution component, which includes a conveying shell 22. The conveying shell 22 is fixedly sleeved on the outside of the rotating rod 7. Multiple discharge pipes 24 are fixedly connected to the outer surface of the conveying shell 22. A cover plate 23 is connected to one side of the conveying shell 22 through a bearing. Two fixing columns 21 are fixedly provided on one side of the cover plate 23. The fixing columns 21 are fixedly connected to the inner wall of the mixing tank 1. A conveying pipe 20 is connected to one side of the cover plate 23. A conveying pump 3 is installed on the top of the mixing tank 1. The output end of the conveying pump 3 is fixedly connected to the conveying pipe 20. The additive is sent into the conveying shell 22, which rotates synchronously with the rotating rod 7, and then evenly thrown out through multiple discharge pipes 24, realizing the dynamic dispersion and mixing of the additive and the main material, and solving the problem of uneven local concentration caused by traditional single-point feeding.

[0034] In order to further avoid the occurrence of stirring dead zones, the device adopts the following technical solution: two fixed blades 9 are fixedly provided at the lower end of the rotating rod 7. Through the synergistic effect of the fixed blades, stirring dead zones can be further avoided.

[0035] To achieve the purpose of sealing, the device adopts the following technical solution: a sealing ring 26 is sleeved on the outside of the connecting rod 11. The sealing ring 26 is located inside the rotating rod 7 and is installed at the connection between the connecting rod 11 and the rotating rod 7. This can effectively prevent materials from seeping into the inner groove, avoid the toothed plate and gears from getting stuck due to material contamination, and ensure the stability and service life of the transmission structure.

[0036] To achieve the purpose of feeding and discharging materials, the device adopts the following technical solution: the top of the mixing tank 1 is fixedly provided with a feeding shell 5, and the bottom of the mixing tank 1 is fixedly provided with a discharge pipe 6. The feeding shell 5 adopts a funnel-shaped design to facilitate the rapid input of raw materials. The discharge pipe 6 is equipped with a valve control to facilitate precise control of the discharge speed and discharge volume.

[0037] To achieve the purpose of support, the device adopts the following technical solution: multiple support columns 2 are fixedly provided at the bottom of the mixing tank 1. The support columns 2 are designed to enhance the overall stability of the device through symmetrical distribution, so as to avoid displacement or tilting caused by equipment vibration during the mixing process.

[0038] In order to achieve the purpose of heating, the device adopts the following technical solution: a heating plate 19 is embedded in the inner wall of the mixing tank 1, and the annular heating plate 19 embedded in the inner wall of the mixing tank 1 can achieve uniform heating.

[0039] The usage process of this utility model is as follows: chemical raw materials are conveyed into the mixing tank 1 through the feed shell 5. The funnel-shaped design of the feed shell 5 allows the raw materials to enter the mixing tank 1 quickly and smoothly, reducing the spillage of raw materials during the feeding process. If liquid additives need to be added according to production needs, the conveying pump 3 is started to convey the additives to the inside of the conveying shell 22 through the conveying pipe 20.

[0040] When the motor 16 is started, the motor 16 drives the transmission shaft 17 to rotate. The rotation of the transmission shaft 17 is transmitted to the second gear 18 fixed to its outside, causing the second gear 18 to rotate. Since the second gear 18 meshes with the third gear 25, the rotation of the second gear 18 will drive the third gear 25 to rotate, which in turn will drive the rotating rod 7 fixedly connected to the third gear 25 to rotate. The rotation of the rotating rod 7 will simultaneously drive the movable blade 13 and the fixed blade 9 to rotate. During the rotation, the movable blade 13 and the fixed blade 9 will stir the chemical raw materials inside the mixing tank 1.

[0041] During the mixing process, the mixing effect can be optimized by adjusting the angle of the movable blades 13 according to the viscosity, ratio, and other characteristics of the chemical raw materials. Activating the hydraulic push rod 15 causes its output end to push or pull the toothed plate 10 within the inner groove 8. Because the toothed plate 10 meshes with the first gear 12, the movement of the toothed plate 10 drives the first gear 12 to rotate. The first gear 12 is fixedly sleeved on the outside of the connecting rod 11, so the rotation of the first gear 12 drives the connecting rod 11 to rotate. One end of the connecting rod 11 is fixedly connected to the movable blades 13 via a connecting block 27. The rotation of the connecting rod 11 drives the connecting block 27 to rotate, which in turn causes the movable blades 13 to rotate. This allows control of the mixing angle of multiple movable blades 13. By adjusting the angle of the movable blades 13, the mixing requirements of different materials can be adapted, expanding the mixing range, eliminating dead zones, and improving mixing uniformity.

[0042] Meanwhile, the rotation of the rotating rod 7 will drive the conveying shell 22 fixedly sleeved on its outside to rotate. The rotation of the conveying shell 22 will in turn drive the multiple discharge pipes 24 fixedly connected to its outer surface to rotate. The additives that enter the conveying shell 22 will be dispersed and thrown out from the multiple discharge pipes 24 as the conveying shell 22 and the discharge pipes 24 rotate, and fall evenly into the mixing tank 1 to mix with the chemical raw materials. This avoids the problem of excessively high local concentration caused by traditional single-pipe addition and greatly improves the mixing efficiency.

[0043] After mixing is complete, turn off the motor 16, hydraulic push rod 15, conveying pump 3 and heating plate 19, etc. After the equipment has completely stopped running, open the discharge pipe 6 at the bottom of the mixing tank 1 and discharge the mixed material from the discharge pipe 6. The discharge pipe 6 can be equipped with a valve. By controlling the opening and closing of the valve, the discharge speed and discharge volume can be precisely controlled.

[0044] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
