Description

Technical Field

[0001] The utility model relates to the technical field of nano calcium carbonate production, in particular to a raw material pre-treatment mechanism for the production of spherical nano calcium carbonate. Background Art

[0002] Nano calcium carbonate is also called ultrafine calcium carbonate. When used in ink products, nano calcium carbonate demonstrates excellent dispersibility, transparency, gloss, ink absorbency and drying properties. Nano calcium carbonate is used as an ink filler in resin-based inks, and has the advantages of good stability, high gloss, no effect on the drying properties of printing inks, and strong adaptability. That is, the quality of nano calcium carbonate is relatively high, and therefore the requirements for the raw materials used in the production of nano calcium carbonate are more stringent. Accordingly, before grinding nano calcium carbonate, the raw calcium carbonate stone used as the raw material needs to be cleaned to prevent dust and debris on the raw calcium carbonate stone from entering the grinding process, causing the impurities in the produced nano calcium carbonate to exceed the standard, affecting product quality.

[0003] After checking the public (announcement) number: CN219130144U, a raw material pretreatment device for the production of spherical nano calcium carbonate is disclosed. This technology discloses "a raw material pretreatment device for the production of spherical nano calcium carbonate, including a main body, an outer drum, an inner drum and a spray module, the upper part of the main body is provided with a connecting groove for installing the outer drum, the outer drum is provided with a through cavity, the inner drum is connected to the inside of the outer drum, the inner drum is provided with a cleaning module for cleaning the nano calcium carbonate raw stone, the spray module is located inside the inner drum and adapted to the inner drum" and other technical solutions, with "the outer drum connected to the main body and rotatable and the inner drum can be used to accommodate the calcium carbonate stone, and the toggle plate provided on the inner wall of the inner drum can make the calcium carbonate stone rotate evenly and effectively to ensure the cleaning effect" and other technical effects;

[0004] Although the above scheme adopts a method of using a drum to drive the stone to flip and clean it through the central spray pipe inside, there is a significant problem: since the spray pipe is located in the center of the drum, the stone may directly collide with it during the flipping process, which may not only cause the spray pipe to rupture or deform, affecting its service life, but also once the spray pipe is covered or blocked by the stone, the effect of the entire cleaning process will be greatly reduced, and the stone cannot be completely cleaned. Utility Model Content
