Description

Technical Field

[0001] This utility model relates to the technical field of lime production equipment, and in particular to a lime vertical kiln batching premixing device. Background Technology

[0002] In the lime vertical kiln production process, premixing of raw materials is a crucial step in ensuring calcination quality, and the performance of the equipment directly affects the purity of the lime product and production efficiency. Currently, most lime vertical kiln premixing devices on the market suffer from significant technical bottlenecks.

[0003] Existing premixing devices generally employ a fixed structural design, with the mixing components and premixing tank connected by welding or bolts, making rapid separation difficult. This structure requires material to be discharged through a bottom outlet, which easily leads to blockages, especially for highly viscous materials, often requiring manual unblocking, which is time-consuming and labor-intensive. Furthermore, numerous dead zones exist between the mixing components and the tank, making it difficult to thoroughly clean residual material. Long-term accumulation of residual material inside the tank not only affects the proportioning accuracy of subsequent batches but may also contaminate new materials due to oxidation and deterioration, reducing the quality of lime products. In addition, to thoroughly clean internal residual material, operators must disassemble and reassemble the equipment multiple times, increasing labor intensity, extending equipment downtime, and reducing production efficiency.

Detailed Implementation

[0023] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0024] Reference Figure 1-3 A lime vertical kiln batching premixing device includes a premixing box 1, as shown in the figure. The bottom of the premixing box 1 is also provided with multiple support legs 2. The premixing box 1 is provided with a rotating frame 4, as shown in the figure. The rotating frame 4 is fixedly provided with a handle 6.

[0025] Multiple stirring rods 5 are fixedly mounted on the rotating frame 4. A mounting cover 3 and a base plate 19 are rotatably mounted on the rotating frame 4. The mounting cover 3 and the base plate 19 are connected to the premix box 1 through a positioning mechanism. A connecting groove 9 is provided on the bottom wall of the premix box 1. A drive motor 8 is provided at the bottom of the premix box 1. The drive motor 8 is connected to the rotating frame 4 through a plugging mechanism. There is an active chamber 12 inside the rotating frame 4. An active block 13 is provided in the active chamber 12 through a first elastic mechanism. A sliding rod 15 is provided in the active chamber 12. A limiting frame 16 is slidably mounted on the sliding rod 15 through a second elastic mechanism. A limiting groove 18 is provided on the inner wall of the connecting groove 9. A drag frame 7 extending to the outside of the rotating frame 4 is fixedly connected to the active block 13.

[0026] The positioning mechanism includes a positioning block 20 fixedly mounted on the mounting cover 3 and the base plate 19, and a positioning groove 21 corresponding to the positioning block 20 is provided on the premixing tank 1. With the above-mentioned positioning block 20 and positioning groove 21, when the rotating frame 4 and the stirring rod 5 rotate in the premixing tank 1, the mounting cover 3 and the base plate 19 will not rotate.

[0027] Preferably, the insertion mechanism includes a plug rod 10 fixedly mounted on the output shaft of the drive motor 8, and a slot 11 corresponding to the plug rod 10 on the rotating frame 4. The plug rod 10 is connected to the output shaft of the drive motor 8 via a coupling and is in the shape of a regular hexagonal prism. The slot 11 is adapted to the shape of the plug rod 10. This shape design allows the rotating frame 4 to rotate synchronously after the drive motor 8 is started, and the two can also be easily separated.

[0028] The first elastic mechanism includes a vertical spring 14 disposed within the movable chamber 12, with both ends of the vertical spring 14 connected to the inner wall of the movable chamber 12 and the outer wall of the movable block 13, respectively. The elastic potential energy provided by the vertical spring 14 enables the movable block 13 to be pressed down, and its elastic potential energy is sufficient to ensure that the position of the movable block 13 is fixed when no strong external force is involved.

[0029] The second elastic mechanism includes a horizontal spring 17 disposed within the movable chamber 12, with both ends of the horizontal spring 17 connected to the outer walls of the two limiting frames 16 respectively. The elastic potential energy provided by the horizontal spring 17 enables the dragging of the limiting frames 16, allowing the limiting frames 16 to move horizontally after the movable block 13 rises, thus enabling the two limiting frames 16 to move closer together.

[0030] Both the movable block 13 and the limiting frame 16 are provided with inclined parts, and the inclined parts on both the movable block 13 and the limiting frame 16 are polished. It is precisely because of the inclined parts that the limiting frame 16 can move horizontally when the movable block 13 is raised and lowered.

[0031] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] The drive motor 8 drives the rotating frame 4 to rotate synchronously via a mating mechanism (hexagonal insert 10 and slot 11). Multiple stirring rods 5 on the rotating frame 4 thoroughly mix the materials in the premixing tank 1. The mounting cover 3 and the base plate 19 are fixed by the engagement of the positioning block 20 and the positioning groove 21, ensuring that they do not rotate with the rotating frame 4, thus guaranteeing the stability of the mixing process. After mixing is complete, the drive motor 8 is turned off, and the drag frame 7 is pulled vertically upwards, causing the movable block 13 to rise against the elastic force of the vertical spring 14. During the ascent of the movable block 13, its inclined portion interacts with the inclined portion of the limiting frame 16, forcing the limiting frame 16 to move horizontally against the tension of the horizontal spring 17 and approach, ultimately disengaging from the limiting groove 18. Finally, the rotating frame 4, stirring rod 5, mounting cover 3 and bottom plate 19 can be separated vertically upward from the premixing box 1 as a whole. At this time, the bottom plate 19 can hold the material and scrape off the residual material on the inner wall of the premixing box 1, which is convenient for quick discharge and cleaning. After the rotating frame 4 and stirring rod 5 and other components are separated, it is also convenient to clean the stirring rod 5 and other components.

[0034] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
