Description

Agitator, agitator mechanism and agitator device Technical Field

[0001] This utility model belongs to the technical field of mixing equipment, specifically relating to a mixing paddle, mixing mechanism and mixing device. Background Technology

[0002] Mixing equipment is a key piece of equipment for mixing and fully reacting different materials. The rotation of the agitator drives the flow and thorough mixing of materials within the container. During operation, the motor's power, reduced in speed by a reducer, drives the agitator shaft to rotate, causing the agitator to move and thoroughly mix the materials in the container, generating the necessary circulation or shearing to achieve the mixing and reaction of different materials. The agitator blade is a crucial component of the mixing equipment, directly affecting the mixing effect and material handling quality. It typically has multiple blades of various shapes, usually mounted on the agitator shaft to form a turbine-like structure, suitable for mixing high-viscosity, high-volume-flow-rate colloidal materials.

[0003] In the prior art, when stirring high-viscosity materials, the high internal friction of the materials makes them difficult to flow. As a result, some areas may mix well, but other areas may not mix sufficiently. This is especially true in the side walls and bottom areas of the mixing container, where the materials may not be able to be stirred sufficiently, leading to uneven mixing. Some materials may also stick to the side walls and bottom of the mixing container. This results in poor adaptability and practicality. Summary of the Invention

[0004] This utility model provides a stirring paddle, stirring mechanism, and stirring device, which aims to solve the problem of material adhering to the bottom of the stirring container due to the high viscosity of the material in existing stirring equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a stirring paddle, comprising:

[0006] Rotary seat;

[0007] Two stirring rods are provided, and each stirring rod is arranged circumferentially around the axis of the rotating seat; one end of each stirring rod is connected to the rotating seat, and the other end extends downward in a spiral shape;

[0009] In one possible implementation, the cross-section of each of the extrusion rods is an inverted isosceles trapezoid.

[0010] In one possible implementation, each of the stirring paddles further includes an adjusting scraper, which is slidably disposed on one of the extrusion surfaces of the extrusion rod, and slides along the inclination angle of the extrusion surface.

[0011] In one possible implementation, the adjusting scraper plate is provided with a connecting screw;

[0012] The adjusting scraper plate is provided with a long through hole for the connecting screw to pass through, and the stirring rod is provided with a threaded hole for the connecting screw to be threaded.

[0013] In one possible implementation, each of the stirring rods has a helical surface that corresponds to the sidewall of the stirring container and pushes the material downward.

[0014] In one possible implementation, the rotary seat includes:

[0015] The connecting shaft is set vertically.

[0016] Two connecting beams are provided, and the two connecting beams are arranged circumferentially on the connecting shaft along the axis of the connecting shaft. One end of each connecting beam is integrally connected to the connecting shaft, and the other end of each connecting beam extends outward and is connected to the corresponding stirring rod.

[0017] In one possible implementation, the stirring mechanism includes two stirring blades, which are spaced apart in a horizontal direction, and the extrusion rod in one of the stirring blades is perpendicular to the extrusion rod in the other stirring blade.

[0018] In one possible implementation, the stirring device includes a stirring mechanism.

[0031] Please refer to Figures 1 to 5 together. The stirring paddle 10 provided by this utility model will now be described. The stirring paddle, stirring mechanism, and stirring device include a rotating base 11, stirring rods 12, and extrusion rods 13. There are two stirring rods 12, which are arranged annularly at intervals around the axis of the rotating base 11. One end of each stirring rod 12 is connected to the rotating base 11, and the other end extends downward in a spiral shape. The extrusion rod 13 is horizontally arranged below the rotating base 11, and its two ends are respectively connected to the extension ends of the two stirring rods 12. The two sides of the extrusion rod 13 have extrusion surfaces with angles equal to the helical angles of each stirring rod 12.

[0032] Compared with the prior art, the stirring paddle, stirring mechanism, and stirring device provided in this embodiment are equipped with a stirring paddle 10. Two spirally extending downward stirring rods 12 connected to the rotating base 11 push the material on the inner wall of the stirring container downwards. Extrusion rods 13 are provided at the extended ends of the two stirring rods 12, which can stir the material at the bottom of the stirring container through the extrusion of the extrusion rods 13. The stirring mechanism, with its two stirring paddles 10, can thoroughly stir the material in the stirring container, ensuring uniform mixing and preventing material from adhering to the side walls and bottom of the stirring container. This design offers good adaptability and practicality.

[0033] The spiral design of the stirring rod 12 generates a downward thrust during the stirring process, promoting the circulation of materials and improving the uniformity of stirring. The extrusion rod 13 can extrude materials, enhancing the stirring effect.

[0034] In some embodiments, the extrusion rod 13 may adopt the structure shown in Figures 1 and 5. Referring to Figure 2, the cross-section of each extrusion rod 13 is an inverted isosceles trapezoid.

[0035] The cross-section of the extrusion rod 13 is an inverted isosceles trapezoid, which makes the extrusion rod 13 more stable when extruding materials and can better match the spiral structure of the stirring rod 12.

[0036] The cross-section of an inverted isosceles trapezoid can be understood as the long base of the isosceles trapezoid being located above the isosceles trapezoid. The cross-section of the extrusion rod 13 can also be an inverted isosceles trapezoid.

[0037] In some embodiments, the stirring paddle 10 may adopt the structure shown in FIG2. Referring to FIG2, each stirring paddle 10 further includes an adjusting scraper 14, which is slidably disposed on one of the extrusion surfaces of the extrusion rod 13, and the adjusting scraper 14 slides along the inclination angle of the extrusion surface.

[0038] The adjustable scraper 14 can scrape off the material on the wall of the mixing container, reducing material residue. At the same time, its position can be adjusted as needed to adapt to different mixing requirements.

[0039] In some embodiments, the adjusting scraper 14 can adopt the structure shown in FIG2. Referring to FIG2, the adjusting scraper 14 is provided with a connecting screw.

[0040] The adjusting scraper 14 is provided with a long through hole for the connecting screw to pass through, and the stirring rod 12 is provided with a threaded hole for the connecting screw to be threaded.

[0041] The position of the scraper 14 can be easily adjusted by connecting the screw and the threaded hole, making the operation simple.

[0042] In some embodiments, the stirring rod 12 may adopt the structure shown in FIG5. Referring to FIG5, each stirring rod 12 has a helical curved surface that corresponds to the side wall of the stirring container and pushes the material downward.

[0043] The stirring rod 12 extends downward in a spiral shape, which can be understood as the two stirring rods 12 being arranged in a double spiral structure. Refer to Figures 1 to 5. The spiral surface of the double spiral structure is adapted to the side wall of the stirring container.

[0044] The spiral surface of the stirring rod 12 can better fit the side wall of the mixing container, pushing the material downward and promoting the circulation of the material.

[0045] The stirring paddle 10 also includes two auxiliary adjustment plates 15. Each auxiliary adjustment plate 15 can be set on the corresponding stirring rod 12. The distance between the auxiliary adjustment plate 15 and the side wall of the stirring container can be adjusted to stir the material on the side wall of the stirring container.

[0046] In some embodiments, the rotating base 11 can adopt the structure shown in Figures 1 to 5. Referring to Figures 1 to 5, the rotating base 11 includes a connecting shaft 111 and a connecting beam 112. The connecting shaft 111 is arranged in a vertical direction. Two connecting beams 112 are provided, and the two connecting beams 112 are arranged annularly at intervals on the connecting shaft 111 along the axis of the connecting shaft 111. One end of each connecting beam 112 is integrally connected to the connecting shaft 111, and the other end of each connecting beam 112 extends outward and is connected to the corresponding stirring rod 12.

[0047] The structural design of the rotating base 11 enables it to stably support the stirring rod 12, ensuring the stability of the stirring process.

[0048] The connecting shaft 111 and connecting beam 112 of the rotating seat 11 can be made of metal and manufactured by casting or machining. The stirring rod 12 can be made of metal tubing and bent into a spiral shape. The extrusion rod 13 can be made of metal sheet and cut and welded into an inverted isosceles trapezoid. The adjusting scraper 14 can be made of plastic or rubber and manufactured by injection molding or compression molding.

[0049] Based on the same inventive concept, this application also provides a stirring mechanism that can adopt the structure shown in Figures 3 and 4. Referring to Figures 3 and 4, the stirring mechanism includes two stirring paddles 10, which are arranged at intervals along the horizontal direction, and the extrusion rod 13 in one stirring paddle 10 is arranged perpendicularly to the extrusion rod 13 in the other stirring paddle 10.

[0050] The two stirring paddles 10 work together, and the extrusion rod 13 is set vertically to further improve the uniformity and efficiency of stirring.

[0051] Based on the same inventive concept, this application also provides a stirring device that can adopt the structure shown in Figures 3 and 4. Referring to Figures 3 and 4, the stirring device includes a stirring mechanism.

[0052] The mixing device employs the aforementioned mixing mechanism, which enables efficient and uniform mixing, thereby improving product quality.

[0053] Connect the mixing device to a power source and start it to mix the materials. During the mixing process, the position of the scraper 14 can be adjusted as needed to achieve the best mixing effect.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
