Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate production homogenization, and specifically to a calcium carbonate production homogenization device which is convenient for cleaning the inner wall of a homogenization bin. Background Art

[0002] In calcium carbonate production, the inner walls of the homogenizer are often affected by dust and sediment, making cleaning difficult. With increasing demands for production efficiency and product quality, developing a technology for easily cleanable inner walls of the homogenizer is particularly important. Traditional devices often use fixed designs, which are time-consuming and labor-intensive to clean, impacting the production process. Therefore, to address this issue, researchers have begun exploring the use of detachable, easy-to-maintain designs combined with automated cleaning systems or specific coatings to improve cleaning efficiency, reduce downtime, and ensure product consistency and purity. In this way, the needs of modern industry can be better met and higher production efficiency can be achieved.

[0003] The patent specification with the announcement number CN 221693549 U discloses a calcium carbonate production homogenizing device that is convenient for cleaning the inner wall of the homogenizing bin. The device comprises a homogenizing bin, a feeding pipe installed at the top of the homogenizing bin, a feeder connected to one end of the feeding pipe inside the homogenizing bin, a driven gear ring fixed to the top of the feeder, a fixed frame installed inside the homogenizing bin, a main shaft rotatably provided on the surface of the fixed frame, and a stirring rod fixedly connected to the surface of the main shaft. The utility model drives the feeder to rotate to generate a centrifugal effect after the powder material enters the feeder, and the powder inside the feeder is evenly sprinkled out from the surface feeding hole, and the powder falls evenly. Then, the main shaft drives the stirring rod to rotate and stir the powder inside the homogenizing bin for homogenization, thereby improving the homogenization efficiency and quality. At the same time, when the stirring rod rotates to stir the powder, it also drives the scraper to scrape and clean the powder on the inner wall of the homogenizing bin, making the inner wall of the homogenizing bin easy to clean and maintain.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned calcium carbonate production homogenizing device that is convenient for cleaning the inner wall of the homogenizing bin has the following problems: the device cannot grind and crush the large fixed particles remaining in the calcium carbonate dust, and the homogenization effect is limited. At the same time, the device cannot clean the dust at the bottom, and it is not easy to collect and process it in a centralized manner. Therefore, we proposed a calcium carbonate production homogenizing device that is convenient for cleaning the inner wall of the homogenizing bin. Utility Model Content
