[0024] See also Figure 1-Figure 5 This embodiment provides a device for preparing ultra-high specific surface area nano-calcium carbonate, comprising a barrel 1, a motor 6 is installed on the top of the barrel 1, and a discharge valve 5 is installed inside the barrel 1; The front of the inner wall of the barrel body 1 is fixedly connected to a partition, and the partition is provided with an inclined groove to facilitate the discharge of the discharge valve 5. The top of the inner wall of the barrel body 1 is rotatably connected to the first rotating rod 21 through a bearing, and the outer wall of the first rotating rod 21 is fixedly connected to the connecting rod 23. The front of the inner wall of the barrel body 1 is fixedly connected to the gear ring 22, and the top of the connecting rod 23 is rotatably connected to the second rotating rod 24 through a bearing. The second rotating rod 24 movably passes through the connecting rod 23 and extends to the bottom. The outer wall of the second rotating rod 24 is fixedly connected to the first circular gear 25, and the bottom of the second rotating rod 24 is fixedly connected to the first elastic telescopic rod. 27. The first elastic telescopic rod 27 has a fixed outer wall at the bottom thereof, and a first crushing plate 28 and a second crushing plate 29 are fixedly connected thereto. A protrusion 26 is fixedly connected to the top of the partition. The inner wall of the barrel body 1 is equipped with a lifting device 3 for delivering the raw materials on the top of the partition to the top of the inner wall of the barrel body 1. The barrel body 1 is equipped with a cleaning device 4 for cleaning the inner wall of the barrel body 1. The first rotating rod 21 and the second rotating rod 24 are driven by a motor 6 to rotate the first crushing plate 28 and the second crushing plate 29, thereby achieving efficient stirring of the reaction materials and promoting the production of nano-calcium carbonate. The first elastic telescopic rod 27 is composed of a thick rod and a thin rod, and the thin rod is slidably connected to the inside of the thick rod. The first crushing plate 28 is fixedly connected to the outer wall of the thin rod, and the second crushing plate 29 is fixedly connected to the outer wall of the thick rod. During the stirring process, the first elastic telescopic rod 27 automatically expands and contracts according to the protrusion 26 on the top of the partition, so that the first crushing plate 28 and the second crushing plate 29 are always in contact with the material. The discharge valve 5 is fixedly connected to the bottom of the partition, the first circular gear 25 is engaged with the ring gear 22, the first rotating rod 21 is movable through the barrel body 1 and extends to the top, and its extended end is fixedly connected to the output end of the motor 6. The motor 6 drives the first circular gear 25 to rotate through the first rotating rod 21, and the first circular gear 25 is engaged with the ring gear 22, driving the second rotating rod 24 to rotate. The rotation of the second rotating rod 24 is transmitted to the first crushing plate 28 and the second crushing plate 29 through the first elastic telescopic rod 27, thereby realizing stirring of the reaction material.

[0025] When the above-mentioned equipment is in use, the raw materials are fed into the material feeding port at the top of the barrel body 1, and the motor 6 is started. The motor 6 drives the connecting rod 23 to rotate, and the connecting rod 23 drives the first circular gear 25 to slide with the inner wall of the ring gear 22, and drives the first circular gear 25 to rotate through the ring gear 22, and the first circular gear 25 drives the second rotating rod 24 to rotate, and the second rotating rod 24 drives the first elastic telescopic rod 27 to rotate. When the first elastic telescopic rod 27 rotates, it drives the first crushing plate 28 and the second crushing plate 29 to rotate, and the connecting rod 23 drives the first elastic telescopic rod 27 to revolve. When the first elastic telescopic rod 27 encounters the protrusion 26, the protrusion 26 will squeeze the first elastic telescopic rod 27. When the first elastic telescopic rod 27 is squeezed, it drives the second crushing plate 29 to rise, and the raw materials are squeezed and crushed by the first crushing plate 28 and the second crushing plate 29, further improving the mixing efficiency. During the rotation, the fan 7 at the bottom cools the inside of the barrel body 1. Example 2

[0026] See also Figure 2-Figure 7 Based on the first embodiment, the lifting device 3 includes a vertical rod 31, which is fixedly connected to the top of the partition. A lifting plate 32 is slidably connected to the outer wall of the vertical rod 31. The structure of the lifting device 3 is described in detail. Through the cooperation of the vertical rod 31 and the lifting plate 32, the raw materials are lifted, so that the raw materials can be smoothly transported from the top of the partition to the top of the inner wall of the barrel body 1, providing convenience for subsequent processing. The vertical rod 31 is fixedly connected to the top of the partition, and the lifting plate 32 is slidably connected to the outer wall of the vertical rod 31. When the raw materials need to be lifted, the first rotating rod 21 drives the lifting plate 32 to slide upward along the vertical rod 31, bringing the raw materials on the top of the partition to the top of the inner wall of the barrel body 1. The bottom of the first rotating rod 21 is fixedly connected to a connecting block 33, the bottom of the connecting block 33 is fixedly connected to a first conical block 34, and the bottom of the lifting plate 32 is fixedly connected to a second conical block 35. The provision of the first conical block 34 and the second conical block 35 increases the linkage between the lifting device 3 and the first rotating rod 21, making the lifting process more stable and reliable and improving the overall coordination of the device. The connecting block 33 at the bottom of the first rotating rod 21 is fixedly connected to the first conical block 34, and the bottom of the lifting plate 32 is fixedly connected to the second conical block 35. When the first rotating rod 21 rotates, the interaction between the first conical block 34 and the second conical block 35 drives the lifting plate 32 to slide upward along the vertical rod 31, thereby lifting the raw materials.

[0027] When the above-mentioned equipment is in use, the first rotating rod 21 drives the connecting block 33 to rotate, and the connecting block 33 drives the first conical block 34 to rotate. When the first conical block 34 rotates to the bottom of the second conical block 35, it squeezes the second conical block 35 to move toward the top, and the second conical block 35 drives the lifting plate 32 to rise. The lifting plate 32 drives the raw materials at the top to rise to prevent the raw materials at the bottom from sinking to the bottom. Example 3

[0028] See also Figure 2-Figure 7On the basis of embodiment 1, the cleaning device 4 includes a scraper 41, which is slidably connected to the top of the partition, and a slide groove for the sliding of the scraper 41 is opened on the top of the partition. A trigger block 42 is hinged on the back of the scraper 41, and a second elastic telescopic rod 45 is fixedly connected to the back of the trigger block 42. The top of the partition is mirror-mounted with a fixed block 44, and the side of the fixed block 44 is equipped with a spring. The side of the connecting rod 23 is fixedly connected to the driving rod 43. Through the cooperation of the scraper 41, the trigger block 42, the second elastic telescopic rod 45, the fixed block 44 and the spring, the automatic cleaning function of the inner wall of the barrel body 1 is realized, preventing the raw materials from adhering to the inner wall and affecting the preparation effect and the normal operation of the equipment. The scraper 41 is slidably connected in the slide groove at the top of the partition, and the back of the trigger block 42 is fixedly connected to the second elastic telescopic rod 45. The elastic action of the second elastic telescopic rod 45 makes the scraper 41 in close contact with the inner wall of the barrel body 1. When the drive rod 43 on the side of the connecting rod 23 moves, the squeeze rod and the spring cooperate to drive the scraper 41 to slide in the chute, cleaning the inner wall of the barrel 1. The bottom of the drive rod 43 is provided with an inclined slot for pushing the trigger block 42. The two ends of the spring are fixedly connected to the left and right sides of the scraper 41 respectively. The second elastic telescopic rod 45 has a large elastic coefficient.

[0029] When the above-mentioned equipment is in use, the connecting rod 23 drives the driving rod 43 to move, and the driving rod 43 drives the extrusion rod to rotate clockwise. When the driving rod 43 contacts the trigger block 42, it drives the scraper 41 to slide, and the spring is compressed to scrape off the raw materials adhering to the inner wall of the barrel body 1. When the scraper 41 contacts the fixed block 44, the driving rod 43 cannot drive the scraper 41 to move. At this time, the second elastic telescopic rod 45 will be squeezed to make the trigger block 42 rotate counterclockwise with the hinge point as the center of the circle. The extrusion rod can no longer drive the scraper 41, and the spring drives the scraper 41 to reset.

[0030] When the above-mentioned device is used in a specific manner, the above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the scope of protection of the present invention.
