[0002] Nano calcium carbonate is also called ultrafine calcium carbonate. Its standard name is ultrafine calcium carbonate. The most mature industry for the application of nano calcium carbonate is the plastics industry. It is mainly used in high-end plastic products.

DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-Figure 4 The environmentally friendly nano calcium carbonate preparation device shown in the figure comprises a liquid storage tank 1, a dosing hole 5 is arranged at the top of the liquid storage tank 1, a mounting seat 7 is fixedly connected to the top of the liquid storage tank 1, a driving motor 9 is fixedly installed at the top of the mounting seat 7, a connecting shaft 10 is fixedly connected to the output end at the bottom of the driving motor 9, a stirring rod 13 is fixedly connected to the outer surface of the connecting shaft 10, a bottom box 6 is fixedly connected to the bottom end of the liquid storage tank 1, a threaded rod 11 is connected to the bottom end of the bottom box 6 through a thread, a crank 8 is fixedly connected to the bottom end of the threaded rod 11, a locking rod 12 is rotatably connected to the top of the threaded rod 11, and a bottom wall of the liquid storage tank 1 is installed. Electromagnet 19, unscrew the dosing hole 5 to add hydrochloric acid into the calcium hydroxide raw slurry, then start the drive motor 9 to drive the connecting shaft 10 to rotate, stir the calcium hydroxide raw slurry, so that the calcium hydroxide raw slurry can fully react with the hydrochloric acid, and then the iron ions and other metal ions will be separated from the calcium hydroxide raw slurry. During the reaction process, the circuit is turned on to operate the electromagnet 19 to adsorb the metal ions separated from the solution, so that the calcium hydroxide raw slurry becomes pure. In subsequent production, the pure calcium hydroxide raw slurry can carbonize nano calcium carbonate with better quality and larger quantity, thereby improving production efficiency.

[0021] A liquid inlet 2 is provided on one side of the top of the liquid storage tank 1, a liquid outlet 3 is provided on one side of the bottom of the liquid storage tank 1, and a regulating valve 4 is provided on the surface of the liquid outlet 3. The liquid inlet 2 is used to inject the coarse raw pulp, and the liquid outlet 3 is used to discharge the coarse raw pulp from which the metal ions are separated, which can then be transported to the next process for aging.

[0022] A polygonal groove is provided at the bottom end of the connecting shaft 10, and the top rod of the engaging rod 12 fits with the groove at the bottom end of the connecting shaft 10. The engaging rod 12 cooperates with the connecting shaft 10 through the threaded rod 11. The polygonal clamping block and the clamping groove can make the connection between the engaging rod 12 and the connecting shaft 10 extremely convenient, and also ensure that the connecting shaft 10 can drive the engaging rod 12 to rotate.

[0023] The top of the liquid storage tank 1 is rotatably connected to a rotating block 14, and four upper brackets 15 are fixedly connected to the sides of the rotating block 14. The bottom end of each upper bracket 15 is rotatably connected to a connecting shaft 17. The rotating block 14 enables the entire cleaning mechanism to rotate, thereby facilitating the cleaning of the inner wall of the liquid storage tank 1 and scraping off metal impurities adsorbed on the surface of the electromagnet 19. The connecting shaft 10 does not contact the rotating block 14, but directly passes through the rotating block 14 to reach the bottom of the liquid storage tank 1.

[0024] The bottom end of each connecting shaft 17 is rotatably connected to a lower bracket 16, and a sweeping wheel 18 is fixedly installed on the outer surface of the connecting shaft 17. The lower bracket 16 is connected to the upper bracket 15 through the connecting shaft 17. The sweeping wheel 18 can clean the interior of the liquid storage tank 1 and also sweep away metal impurities adsorbed on the surface of the electromagnet 19.

[0025] Four slots are provided at the bottom end of the lower bracket 16, and the locking rod 12 cooperates with the four slots through the lifting and lowering of the threaded rod 11. The locking rod 12 can be lifted and lowered along with the threaded rod 11, thereby entering the slot of the lower bracket 16 to clamp the lower bracket 16, so that the driving motor 9 can also drive the upper bracket 15 and the lower bracket 16 to rotate at the same time, thereby cleaning the interior of the liquid storage tank 1. Before the locking rod 12 restricts the lower bracket 16, the sweeping wheel 18 will not rotate, thereby not affecting the electromagnet 19 to adsorb metal ions.

[0026] Working principle: After calcining limestone, adding water will form a coarse raw pulp, and the coarse raw pulp will be aged to form a refined raw pulp, which can then be carbonized. Before forming the refined raw pulp, the coarse raw pulp needs to be added into the liquid storage tank 1 from the liquid inlet 2, and then hydrochloric acid is added from the dosing hole 5 to react with the coarse raw pulp. At this time, it is necessary to turn on the drive motor 9 to drive the connecting shaft 10 to rotate, so that the stirring rod 13 will stir the coarse raw pulp, so that the hydrochloric acid can fully react with the coarse raw pulp, and speed up the reaction, saving production time. After the reaction, the metal ions in the coarse raw pulp will precipitate, but still exist in the coarse raw pulp solution. At this time, the circuit needs to be turned on to make the electric When the magnet 19 works, the electromagnet 19 will adsorb the metal ions in the raw pulp, making the raw pulp pure, and the raw pulp can be discharged from the liquid outlet 3 for aging; long-term work requires cleaning of the liquid storage tank 1, and at this time, it is necessary to rotate the crank 8 at the bottom of the liquid storage tank 1 to make the threaded rod 11 rise and fall, driving the locking rod 12 to restrict the lower bracket 16. At this time, when the driving motor 9 drives the connecting shaft 10 to rotate, it will drive the entire cleaning mechanism to rotate, thereby cleaning the inner wall of the liquid storage tank 1, and at the same time, it can also sweep away the metal ions adsorbed by the electromagnet 19, ensuring the cleanliness of the liquid storage tank 1 and facilitating subsequent use.
