Description

Technical Field

[0001] The utility model relates to the technical field of heavy calcium carbonate powder production, in particular to a mixing device for producing active heavy calcium carbonate powder. Background Art

[0002] Heavy calcium carbonate, abbreviated as heavy calcium carbonate, is made by grinding natural carbonate minerals such as calcite, marble, and limestone, while activated heavy calcium carbonate is produced by adding activators (such as fatty acids) to heavy calcium carbonate during the production process for surface activation treatment.

[0003] At present, in the production process of activated heavy calcium carbonate, a mixing device is required to mix heavy calcium carbonate and an active agent. When the workers add heavy calcium carbonate to the mixing device, it is not convenient to filter out the larger particles of impurities in the heavy calcium carbonate, which affects the production of activated heavy calcium carbonate and reduces the mixing efficiency of the activated heavy calcium carbonate.

[0004] In the related art, reference can be made to the Chinese patent with announcement number CN218358770U, which specifically discloses a device for producing and mixing activated heavy calcium carbonate powder. When the device is used, a filtering structure is provided. Specifically, when it is necessary to filter the impurities with larger particles in the heavy calcium carbonate powder, the filter frame is passed through the jack and inserted into the slot. Then, the filter frame and the filter screen can be fixed inside the feed hopper by the cooperation of the fixing plate and the fixing screw. The staff puts the heavy calcium carbonate powder into the feed hopper, and the filter screen in the feed hopper can filter the impurities with larger particles in the heavy calcium carbonate powder. The filtered heavy calcium carbonate powder enters the mixing box through the feed port, thereby not affecting the production of activated heavy calcium carbonate, effectively improving the mixing efficiency of the activated heavy calcium carbonate, and achieving the effect of facilitating the filtering of impurities with larger particles in the heavy calcium carbonate.

[0005] The applicant found that there were deficiencies in the use of the above-mentioned active heavy calcium carbonate powder production mixing device: although the filter screen in the feed hopper can filter out the larger impurities in the heavy calcium carbonate powder, the heavy calcium carbonate powder easily accumulates on the filter screen, causing the filter screen to be blocked, affecting the filtering effect of the heavy calcium carbonate powder, and at the same time reducing the stability of the heavy calcium carbonate powder feeding.

[0006] In view of this, the present technical solution proposes a mixing device for the production of activated heavy calcium carbonate powder, which is convenient for better solving the above-mentioned problems. Utility Model Content
