Description

Technical Field

[0001] The invention relates to the technical field of calcium carbonate processing, in particular to a grinding device for calcium carbonate processing. Background Art

[0002] Calcium carbonate uses limestone as the main raw material. After mechanical crushing and grinding, it forms dry powder or wet powder, and then is graded to form products that meet different particle size requirements. It is suitable for papermaking, plastics, rubber, ink, chemical building materials, sealing materials, daily chemicals, food, medicine and many other fields. The calcium carbonate industry chain formed is called the calcium carbonate industry.

[0003] According to a grinding device for calcium carbonate processing proposed by Chinese patent CN216499594U, in the device, materials are added into the inside of the feed hopper and the second motor is started through the operation panel. The second motor drives the drive shaft to rotate, and then drives the grinding roller and the driven pulley to rotate. The driven pulley rotates and drives the belt to rotate, which in turn drives the driving pulley to rotate and drives the rotating shaft to rotate. The rotating shaft rotates and drives the dividing plate to rotate. The dividing plate rotates and transports the materials to the inside of the device body at intervals. After the materials enter the inside of the device body, they will be ground and crushed by the grinding roller.

[0004] There are some shortcomings in the calcium carbonate processing and grinding device in the prior art. In the prior art, in the process of grinding calcium carbonate solids, large and small pieces of calcium carbonate solids are usually ground together through grinding rollers. During the grinding process, large pieces of calcium carbonate solids are easy to cover small pieces of calcium carbonate solids, making some small pieces of calcium carbonate solids difficult to grind, resulting in uneven grinding. Therefore, before grinding large and small pieces of calcium carbonate solids, they need to be crushed one by one to facilitate grinding. For this reason, we propose a grinding device for calcium carbonate processing. Summary of the invention

During the rotation of the second output shaft 733, the first grinding roller 734 is driven to rotate. During the rotation of the second output shaft 733, the driving gear 735 and the driven gear 736 are engaged, causing the transmission shaft 737 to rotate with the second grinding roller 738.

[0026] Working principle: when it is necessary to grind large calcium carbonate solids and small calcium carbonate solids, in order to avoid uneven grinding due to the difference in shape and size during the grinding process of large calcium carbonate solids and small calcium carbonate solids, it is necessary to extrude and crush the large calcium carbonate solids and small calcium carbonate solids, so as to improve the grinding effect of the large calcium carbonate solids and small calcium carbonate solids. At this time, the operator puts the large calcium carbonate solids and small calcium carbonate solids into the grinding box 1 from the top, and then turns on the first drive motor 716 to cause the first output shaft 717 to rotate. After the first output shaft 717 rotates, it will drive the first gear 718 to rotate and mesh with the ring gear 712, so as to cause the support frame 715 to slide on the inner wall of the limiting groove 713 through the slider 714, and cause the fixed block 719 to move during the movement of the support frame 715, so as to facilitate the extrusion and crushing of the large calcium carbonate solids and small calcium carbonate solids at different positions inside the grinding box 1; During the movement of the fixed block 719, the sleeve 7111 will be moved with the U-shaped connecting block 7110.

When the first protrusion 7115 is not in contact with the second protrusion 7116, the vibration column 7119 will prompt the extrusion plate 7120 to move downward under the action of gravity, so as to crush the large and small calcium carbonate solids. This process is repeated to facilitate the uniform crushing of the large and small calcium carbonate solids inside the grinding box 1. After the large and small calcium carbonate solids are crushed, the crushed small calcium carbonate pieces will adhere to the surface of the blocking plate 726. In order to facilitate the unified grinding of all the large and small calcium carbonate solids after crushing, it is necessary to block the small calcium carbonate pieces from the bottom. After the crushing is completed, the operator turns on the forward and reverse motor 723 to cause the screw rod 724 to rotate. During the rotation of the screw rod 724, the sleeve block 725 will move, and the blocking plate 726 is limited by the limit block 728 and the cross column 729, so that the two blocking plates 726 can move smoothly on the inner wall of the slide 721. When the two blocking plates 726 are opened, the small calcium carbonate pieces will fall along the inclined plate 7211 inside the grinding box 1, so as to grind the small calcium carbonate pieces. When the small pieces of calcium carbonate fall along the side of the inclined plate 7211, they will fall on the middle of the first grinding roller 734 and the second grinding roller 738. Then, by turning on the second driving motor 732, the second output shaft 733 will be rotated. During the rotation of the second output shaft 733, the first grinding roller 734 will be rotated. During the rotation of the second output shaft 733, the driving gear 735 will be engaged with the driven gear 736, causing the transmission shaft 737 to rotate with the second grinding roller 738.
