Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate powder separation, in particular to a modified calcium carbonate powder separation device. Background Art

[0002] Modified calcium carbonate powder, also known as activated calcium carbonate, is a calcium carbonate product obtained through a special activation treatment. This activation treatment mainly modifies the surface of heavy calcium carbonate, light calcium carbonate or nano calcium carbonate, thereby giving it better performance.

[0003] The purity and quality of modified calcium carbonate powder are closely related. In the production process of modified calcium carbonate powder, in order to further improve the product quality, obtain high-purity modified calcium carbonate powder, and produce products with stable quality and performance, the modified calcium carbonate powder needs to be purified and separated again. When the powdered material is put into the feed port of the traditional partial screening and separation device, it is easy to pile up and form a blockage, thereby affecting the overall work efficiency. Based on these problems, Chinese patent CN219943646U discloses a modified calcium carbonate powder separation device. Through the cooperation of a rotating shaft and an auger blade, after the modified calcium carbonate powder material is poured into the hopper, the modified calcium carbonate powder material can be transported into the screening bin for screening to prevent it from piling up and blocking the hopper, thereby avoiding affecting the screening efficiency.

[0004] In this device, the calcium carbonate powder to be separated is transported to the screening bin by the auger blades. Since the auger blades transport the calcium carbonate powder to a separate position on the top surface of the first screen, the calcium carbonate powder at this position will pile up higher and higher, which will not only affect the separation speed of the calcium carbonate powder, but also the higher and higher calcium carbonate powder will contact the bottom end of the auger blades, causing the conveying outlet of the auger blades to be blocked. At this time, the feed hopper will still be blocked. Utility Model Content
