[0002] Calcium carbonate powder is widely used as a filling and modifying material in industries such as plastics, rubber, and coatings. It can not only improve the rigidity, hardness, wear resistance, heat resistance, and dimensional stability of composite materials, but also in order to enhance the wettability of calcium carbonate in polymers, eliminate the high surface potential energy, and improve its dispersion performance in composite materials, calcium carbonate needs to be modified.

[0003] Chinese Patent with the authorization announcement number CN217527448U discloses a modification device for activating calcium carbonate powder.

[0004] However, during use, there is a phenomenon that calcium carbonate particles are left in the holes in the middle position of the moving grinding disc, resulting in the inability of the moving grinding disc and the fixed grinding disc to effectively grind this part of the calcium carbonate particles.

[0024] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0025] As Figures 1-5 shown, a device for highly efficient activation of calcium carbonate powder includes an outer barrel 1. A feeding pipe 2 is fixedly connected to the lower side of the outer barrel 1. A lower support 10 is fixedly connected to the lower end inside the outer barrel 1. An upper end of the lower support 10 is fixedly connected to a first elastic support frame 11. An upper end of the first elastic support frame 11 is fixedly connected to a fixed grinding disc 7. An upper support 4 is fixedly connected to the upper end inside the outer barrel 1. A vertically arranged rotating pipe 5 is rotatably connected inside the upper support 4. A lower end of the rotating pipe 5 is screwed to a moving grinding disc 6 located above the fixed grinding disc 7. A feeding round hole 12 communicating with the rotating pipe 5 is opened at the axial center position of the moving grinding disc 6. A servo motor 9 is fixedly connected to the upper support 4, and the servo motor 9 is in transmission connection with the rotating pipe 5;

[0026] At this time, the calcium carbonate powder is input into the inside of the rotating pipe 5. The calcium carbonate powder inside the rotating pipe 5 will automatically fall into the inside of the feeding round hole 12 under the action of gravity. When the servo motor 9 is started, it will drive the rotating pipe 5 to rotate, and the rotating pipe 5 will drive the moving grinding disc 6 to rotate. When the calcium carbonate powder enters between the moving grinding disc 6 and the fixed grinding disc 7, the calcium carbonate powder can be ground by the moving grinding disc 6 and the fixed grinding disc 7. And under the elastic force of the first elastic support frame 11, an upward force will be continuously applied to the fixed grinding disc 7, so that the fixed grinding disc 7 presses the calcium carbonate powder.

[0027] In order to make it more convenient for the calcium carbonate powder to enter the inside of the rotating pipe 5, a feeding hopper 3 is fixedly connected to the upper end of the outer barrel 1. The lower opening of the feeding hopper 3 faces the upper opening of the rotating pipe 5, so that the calcium carbonate powder entering the inside of the feeding hopper 3 can automatically fall into the inside of the rotating pipe 5.

[0028] As Figures 2-4As shown in the figure, an activating liquid inlet mechanism 8 is fixedly connected to the upper end of the moving grinding disc 6. A liquid outlet hole 13 is formed in the moving grinding disc 6 and is communicated with the lower end of the activating liquid inlet mechanism 8. During the grinding process, the activating liquid inside the activating liquid inlet mechanism 8 will penetrate through the liquid outlet hole 13 to the lower side of the moving grinding disc 6 and come into contact with the calcium carbonate powder being ground. Under the grinding of the fixed grinding disc 7 and the moving grinding disc 6, the calcium carbonate powder is fully mixed with the penetrated activating liquid, improving the activation efficiency. Finally, the ground and mixed calcium carbonate powder will be thrown out by centrifugal force from the gap between the fixed grinding disc 7 and the moving grinding disc 6 and fall through the feeding pipe 2 to complete the discharging.

[0029] The activating liquid inlet mechanism 8 includes an annular hollow box body fixedly connected to the upper end of the moving grinding disc 6. A liquid inlet pipe mouth is fixedly connected to the upper side of the annular hollow box body. The activating liquid can be added into the interior of the annular hollow box body through the liquid inlet pipe mouth. A sealing cover is threadedly connected to the upper side of the liquid inlet pipe mouth to achieve the purpose of sealing. A circulation hole communicated with the liquid outlet hole 13 is formed in the lower end of the annular hollow box body, enabling the activating liquid inside the annular hollow box body to flow into the liquid outlet hole 13.

[0030] As Figures 3-5 shown, the core of this technical solution lies in that a top plate 14 is fixedly connected to the upper side inside the feeding round hole 12. A central disc 15 is assembled on the lower side of the top plate 14. A plurality of material pushing plates 16 are assembled on the circumferential side of the central disc 15. At this time, when the moving grinding disc 6 rotates, it will drive the plurality of material pushing plates 16 to rotate through the central disc 15, causing the material pushing plates 16 to push the calcium carbonate powder inside the feeding round hole 12 to the circumferential side, enabling the calcium carbonate powder inside the feeding round hole 12 to effectively enter between the moving grinding disc 6 and the fixed grinding disc 7 and reducing the calcium carbonate powder remaining unground inside the feeding round hole 12.

[0031] Meanwhile, as Figure 4 shown, since the height of the fixed grinding disc 7 continuously changes under the action of the first elastic support frame 11, in order to make the height of the material pushing plate 16 adaptable to the fixed grinding disc 7, enabling the lower side of the material pushing plate 16 to continuously abut against the upper side of the fixed grinding disc 7 and allowing the material pushing plate 16 to push the calcium carbonate powder on the upper side of the fixed grinding disc 7 more thoroughly, a second elastic support frame 21 is fixedly connected to the lower end of the top plate 14, and the central disc 15 is fixedly connected to the lower end of the second elastic support frame 21. At this time, under the elastic force of the second elastic support frame 21, the lower side of the material pushing plate 16 can effectively abut against the upper side of the fixed grinding disc 7.

[0032] As Figures 3-5 shown, the central disc 15 and the material pushing plate 16 are connected by an elastic plate 17. The material of the elastic plate 17 can be spring steel. Under the elastic deformation of the elastic plate 17, the material pushing plate 16 can automatically tilt when the force is relatively large, reducing the phenomenon of the material pushing plate 16 being damaged by force.

[0033] A plurality of second slots 19 are provided on the circumferential side of the center disc 15, and a first slot 18 is provided on one end of the material stripping plate 16 close to the center disc 15. The two ends of the elastic plate 17 are respectively engaged with the inside of the first slot 18 and the second slot 19, thereby realizing the rapid disassembly of the elastic plate 17 and quickly completing the replacement of the elastic plate 17 after the material stripping plate 16 is damaged.

[0034] Both ends of the elastic plate 17 are fixedly connected with L-shaped spring clips 20, which are clamped inside the first slot 18 or the second slot 19. By the friction between the side walls of the L-shaped spring clip 20 and the inner walls of the slot, the L-shaped spring clip 20 can be locked inside the slot, reducing the possibility of the elastic plate 17 falling off.

[0035] The working principle of this utility model is:

[0036] Calcium carbonate powder is fed into the interior of the rotating tube 5, and the calcium carbonate powder inside the rotating tube 5 automatically falls into the interior of the feeding circular hole 12 under the action of gravity. When the servo motor 9 is started, it drives the rotating tube 5 to rotate, and the rotating tube 5 drives the movable grinding disc 6 to rotate. When the movable grinding disc 6 rotates, it drives multiple prying plates 16 to rotate through the central disc 15, and the prying plates 16 pry the calcium carbonate powder inside the feeding circular hole 12 toward the circumferential side, so that the calcium carbonate powder inside the feeding circular hole 12 can effectively enter between the movable grinding disc 6 and the fixed grinding disc 7, thereby reducing the calcium carbonate powder remaining in the feeding circular hole 12 without being ground;

[0037] When the calcium carbonate powder enters between the movable grinding disc 6 and the fixed grinding disc 7, the calcium carbonate powder can be ground by the movable grinding disc 6 and the fixed grinding disc 7. Under the elastic force of the first elastic support frame 11, an upward force is continuously applied to the fixed grinding disc 7, so that the fixed grinding disc 7 pressurizes the calcium carbonate powder.

[0038] During the grinding process, the activation liquid inside the activation liquid inlet mechanism 8 will penetrate into the lower side of the movable grinding disc 6 through the lower liquid hole 13 and come into contact with the ground calcium carbonate powder. Under the grinding of the fixed grinding disc 7 and the movable grinding disc 6, the calcium carbonate powder and the infiltrated activation liquid are fully mixed, thereby improving the activation efficiency. Finally, the ground and mixed calcium carbonate powder will be thrown out from the gap between the fixed grinding disc 7 and the movable grinding disc 6 by centrifugal force, fall through the discharge pipe 2, and complete the discharge.

It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
