Description

Technical Field

[0001] The utility model belongs to the field of filtering and removing impurities boxes, and specifically relates to a chelating agent filtering and removing impurities box. Background Art

[0002] Metal atoms or ions react with ligands containing two or more coordinating atoms to form a complex with a ring structure, which is called a chelate. The ligand substance that can form a chelate is called a chelating agent, also known as a complexing agent. In the preparation process of heavy metal chelating agents, it is usually necessary to screen the raw materials to prevent impurities from affecting the quality of the finished chelating agent.

[0003] A Chinese patent with announcement number CN220214176U discloses an automated chelating agent filtering and impurity removal device, including a shell and a connecting cylinder, the connecting cylinder is fixedly connected to the inner wall of the shell, a coarse filter plate and a fine filter plate are symmetrically fixedly connected to the inner wall of the connecting cylinder, a trapezoidal block is fixedly connected to the inner wall of the shell, and a vertical column is fixedly connected to the upper end surface of the trapezoidal block. The utility model starts the servo motor, and the first cam and the second cam can be driven to rotate through the cooperation between the first rotating rod, the first bevel gear, the second bevel gear and the second rotating rod. When the first cam and the second cam rotate to the upper side, they will knock on the vibration block, causing the coarse filter plate and the fine filter plate to vibrate, so that the filter residue filtered by the coarse filter plate and the fine filter plate enters the collection box through the first collecting port and the second collecting port, so as to prevent the filter residue from blocking the filter holes of the coarse filter plate and the fine filter plate, thereby reducing the quality of the finished heavy metal chelating agent. In the automatic chelating agent filtering and impurity removal device in the application, the chelates on the coarse filter plate and the fine filter plate can be completely discharged into the collection box, resulting in the possibility that the chelating agent that has not been filtered by the coarse filter plate and the fine filter plate is discharged into the collection box, affecting the filtering effect of the chelating agent.

[0004] In view of this, the present utility model is proposed. Utility Model Content
