Description

Technical Field

[0001] The utility model relates to the technical field of nano calcium carbonate, in particular to a nano calcium carbonate crushing device. Background Technique

[0002] Nano calcium carbonate is also called ultra-fine calcium carbonate, and its standard name is ultra-fine calcium carbonate. The most mature industry for the application of nano calcium carbonate is the plastic industry, which is mainly used in high-grade plastic products. It can improve the rheology of plastic masterbatch, improve its formability, and has the function of toughening and reinforcing as a plastic filler, improving the bending strength and bending elastic modulus of plastics, heat distortion temperature and dimensional stability, and at the same time endowing plastics with heat retention properties. Nano calcium carbonate shows excellent dispersibility, transparency, excellent gloss, excellent ink absorption and high drying properties in ink products. Nano calcium carbonate is used as an ink filler in resin-based inks, with the advantages of good stability, high gloss, not affecting the drying performance of printing inks, and strong adaptability.

[0003] The patent publication number CN208288157U discloses a crushing device for nano calcium carbonate production, including a crushing outer shell. A fixed base is arranged directly below the crushing outer shell, and the fixed base is connected to the crushing outer shell through a support frame. Transmission channels are respectively welded on both sides of the crushing outer shell, and the length direction of the transmission channels is fixedly connected to the side wall of the crushing outer shell. The crushing outer shell is a hollow structure, and a second material distribution sieve is arranged inside the crushing outer shell. The outside of the second material distribution sieve is vertically connected to the inner wall of the crushing outer shell, and a first material distribution sieve is arranged directly below the second material distribution sieve. The first material distribution sieve passes through the bottom of the crushing outer shell and communicates with the outside. The two inner walls of the crushing outer shell are connected by a power shaft, which has the advantages of reducing the labor intensity of workers and being simple to use. The above patent has the following deficiencies: During the use of the above patent structure, crushing is carried out by a cutting knife, which causes relatively large wear on the surface of the cutting edge of the cutting knife, and the replacement cycle of the cutting knife is short and time-consuming, which will affect the production efficiency of nano calcium carbonate. In view of this, we propose a nano calcium carbonate crushing device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a nano calcium carbonate crushing device to solve the problems raised in the above background technique.

The right side of the left column 21 is rotationally connected to the first horizontal shaft 23 through a bearing. The eccentric part on the left side of the outer drum 24 is fixedly connected to the right end of the first horizontal shaft 23. The right end of the second horizontal shaft 25 is rotationally connected to the left side of the right column 21 through a bearing. The first horizontal shaft 23 and the second horizontal shaft 25 are concentric shafts. The left end of the second horizontal shaft 25 is fixedly connected to the right center of the inner drum 26. The inner drum 26 is arranged inside the outer drum 24. The first gear ring 27 is fixedly connected to the left inner wall of the outer drum 24. The second gear ring 28 is fixedly connected to the left outer wall of the inner drum 26. The first gear ring 27 meshes with the second gear ring 28. The first horizontal shaft 23 is provided to provide a supporting force for the outer drum 24. The motor 22 is fixedly connected to the left side of the left column 21. The right output end of the motor 22 penetrates through the left and right ends of the left column 21 and is fixedly connected to the left end of the first horizontal shaft 23. The column 21 is provided to provide a supporting force for the motor 22. A tank cover 3 is arranged on the outer wall of the outer drum 24, and a handle 31 is fixedly connected to the front of the tank cover 3.
