Description

Technical Field

[0001] This utility model relates to the field of carbon impregnation tank technology, and in particular to a high-efficiency stirring carbon impregnation tank with double impellers. Background Technology

[0002] The equipment used for leaching is called a leaching tank. There are two types of leaching tanks: air-stirred tanks and mechanically stirred tanks. These tanks can be used for both leaching and purification operations. The appropriate tank is selected based on the specific operating conditions. Generally speaking, air-stirred tanks are suitable for operations involving oxidation, while mechanically stirred tanks are suitable for operations involving reduction.

[0003] In existing technologies, in order to ensure uniformity during the mixing process, a double impeller is usually set up to force the fluid to circulate along the mixing axis. However, the shear force of the upper and lower impellers is insufficient during operation, making it difficult to break up coarse particles or agglomerates, resulting in insufficient circulation and dead zones. In view of this, we propose a double impeller high-efficiency mixing carbon impregnation tank. Utility Model Content
