[0002] In the processing and production of powder and granular materials, multi-component material mixing and conveying is one of the core processes. Currently, most existing material mixing and conveying systems use multiple independent lifting devices to transport various materials separately. This results in high equipment investment costs, large footprints, cumbersome production line layouts, and high equipment maintenance difficulty. Furthermore, traditional mixing methods often involve low-level centralized feeding and mixing, leading to short material mixing strokes, limited dispersion effects, and a high likelihood of uneven material mixing, localized segregation, and poor mixing accuracy and consistency.
[0003] Furthermore, existing equipment struggles to achieve integrated operations of graded and independent conveying of multiple materials, zoned storage, and simultaneous material mixing. Most systems require step-by-step conveying and mixing, resulting in cumbersome processes, poor production continuity, and severely impacting the overall efficiency of material mixing and conveying, as well as the quality of the finished product. Therefore, developing a vertical lifting and grading conveying device for mixed materials that enables graded conveying of multiple materials, high-altitude material mixing, excellent mixing effect, and high structural integration has significant value for production applications.

[0021] See Figures 1-3The illustrated vertical lifting and grading conveying device for mixed materials includes a rotary table and a bucket elevator 3 installed at the center of the rotary table. Multiple radially extending feeding belt conveyors 2 are arranged at the feeding port of the bucket elevator 3, centered on the axis of the rotary table. Multiple discharging belt conveyors 4, corresponding radially to the feeding belt conveyors 2, are arranged at the discharge port of the bucket elevator 3.

The bucket elevator 3 is then rotated to the feeding belt conveyor 2 (b) and the feeding belt conveyor 2 (c) in sequence, conveying materials b and c into the mixing hopper 6. Finally, after being mixed in the mixing hopper 6, the materials are conveyed through the screw conveyor 7.
[0023] The conveying device and method use a bucket elevator 3 to lift different materials to the target height, and then mix the various materials thoroughly in the vertically set mixing hopper 6 to improve the mixing effect.
[0024] In this embodiment, to further provide a rotating structure for the rotary table, the rotary table includes a fixed base 1 and a rotating platform 8. The rotating platform 8 is rotatably mounted within the fixed base 1. A gear ring 15 is disposed on the outside of the rotating platform 8. A drive motor 20 is mounted on the fixed base 1, and a gear 19 meshing with the gear ring 15 is fitted onto the drive motor 20. The drive motor 20 drives the gear 19 to rotate, thereby causing the gear ring 15 and the rotating platform 8 to rotate. This allows the bucket elevator 3 connected to the rotating platform 8 to switch between different feeding positions.
[0025] In this embodiment, the fixed base 1 is provided with a stepped groove 12 for accommodating the rotating platform 8. A rotary bearing 14, sleeved on the rotating platform 8, is installed in the upper groove of the stepped groove 12. A lower arc surface 13 is provided at the opening of the lower groove, and an upper arc surface is provided at the lower edge of the rotating platform 8 to support and contact the lower arc surface 13.

The long straight cylinder 25 is provided with multiple feeding plates staggered inside. When the material below passes through the trapezoidal cylinder 22, it is dispersed by the multiple rotating dispersing blades, and then passes through the multiple feeding plates, rolling in sequence, so that the material is more thoroughly dispersed and mixed.
[0031] In this embodiment, the feeding plate is a vibrating plate 26. Using a downwardly inclined vibrating plate 26 as the feeding plate results in better mixing during the material descent process.
[0032] The present invention also provides a mixing and conveying method, the mixing and conveying method using the aforementioned vertical lifting and grading conveying device for mixed materials, comprising: S1, different materials are sequentially fed into the bucket elevator 3 through the corresponding feeding belt conveyor 2 for lifting and conveying, and then discharged from the corresponding unloading belt conveyor 4 to the mixing hopper 6 for storage. Each different material is stored in a different storage chamber in the mixing hopper 6. S2, after all the materials have been delivered to the designated location, open the bottom discharge gate 23 of all storage chambers and discharge the materials downwards, and disperse the materials through the dispersing device set below the mixing hopper 6.
