Description

Technical Field

[0001] This invention relates to the field of separation and impurity removal technology, and more specifically, to an alumina material separation and impurity removal device for a feeding system. Background Technology

[0002] The alumina distribution airflow impurity removal device in the feeding system works by using airflow to remove dust and impurities from alumina particles, thus achieving the distribution operation. As a key raw material, the purity of alumina directly affects the performance of the final product. Airflow impurity removal can effectively remove dust and impurities from the surface of the particles, preventing impurities from being mixed into subsequent processes and ensuring the high purity of alumina.

[0003] Among the existing published documents, patent publication number CN112845094A discloses an alumina circulation control system and its control method. This alumina circulation control system has high dust and impurity removal efficiency, stable material supply, convenient control, and cost savings, making the dust removal reaction more complete, with high reaction efficiency and good dust removal effect. However, this technology has the following problems.

[0004] During the separation and impurity removal of alumina particles, although the airflow is used to disperse dust and impurities through contact with them, the alumina particles in the actual supply are tightly packed together. This makes it difficult for adjacent alumina particles to form gaps in different directions to achieve reciprocating oscillation during the airflow impurity removal process. As a result, the gaps between alumina particles are narrow. For the airflow to effectively remove impurities, it needs to come into contact with a large area of ​​dust and impurities. The narrow gaps greatly limit the contact range between the airflow and the impurities. The airflow cannot fully act on the dust and impurities, so a large number of impurities still adhere to the alumina particles, resulting in poor alumina separation and impurity removal effect.
