Description

Technical Field

[0001] This application relates to the field of lithium battery material production technology, and more specifically, to a level gauge cleaning device and a slurry tank equipment. Background Technology

[0002] In the grinding and production process of lithium battery materials, the slurry from tank A and tank B needs to be transferred a certain number of times to ensure the particle size quality requirements of the lithium battery materials. The emptying and filling of the slurry tanks are determined by the liquid level signal from a level gauge. If the level gauge malfunctions or its data is inaccurate, the lithium battery material production system will be unable to accurately measure the number of transfer cycles between tank A and tank B, ultimately compromising product quality.

[0003] However, in the precursor production process of lithium battery materials, the slurry from tank A and tank B is reverse-flowed to form a yellow slurry. This yellow slurry contains sugar and is viscous. Since the level gauge probe is always located in the slurry tank, it is easily adhered to by the yellow slurry during the reflow process. If the level gauge probe is not cleaned regularly, the yellow slurry adhering to it will harden and clump, causing the level gauge to malfunction or reduce the accuracy of the level data.

[0004] Currently, cleaning the probe of a level gauge requires manually disassembling the level gauge and manually cleaning the probe. However, cleaning the level gauge probe using existing technology is time-consuming and labor-intensive, and the cleaning effect cannot be guaranteed, thus affecting the working efficiency and production quality of the lithium battery material production system.
