Description

Technical Field

[0001] The present application relates to the technical field of nano-calcium carbonate separation, and in particular to a high-efficiency filter press equipment for the production of nano-calcium carbonate. Background Art

[0002] The particle size of nano calcium carbonate is between 1nm-100nm. Compared with ordinary calcium carbonate, nano calcium carbonate has a special crystal structure and surface electronic structure, and has excellent quantum size effect and surface effect. The carbonization method is the current dominant production process. Nano calcium carbonate is prepared by intermittently bubbling carbon dioxide into lime slurry. The filter press process of nano calcium carbonate is an important step in the production of nano calcium carbonate powder materials. The main purpose is to separate nano-scale calcium carbonate particles from the calcium carbonate suspension to obtain dry, pure nano calcium carbide powder.

[0003] In the process of filtration, in order to improve the efficiency of filtration, the filter cake is usually initially pressurized and filtered before the stock liquid is passed into the filter cake again to penetrate into the filter cake, and then the filtration is continued, so that more nano-calcium carbonate is retained on the filter cake after the filtration is completed. However, in the subsequent process of passing the stock liquid again, the nano-calcium carbonate filtered out accumulates and covers the filter holes, resulting in the subsequent filtrate needing to completely penetrate the nano-calcium carbonate filtered out before it can pass through the filter holes for filtration, resulting in low overall filtration efficiency.

[0004] Therefore, it is necessary to provide a high-efficiency filter press equipment for the production of nano calcium carbonate to solve the problems raised in the above background technology. Summary of the invention
