Description

Technical Field

[0001] This utility model relates to the field of lithium battery material screening technology, specifically a non-contact online monitoring device for material blockage and screen breakage in vibrating screens in the lithium battery industry. Background Technology

[0002] Vibrating screens play a crucial role in the production of lithium-ion battery cathode materials, intercepting and separating foreign objects to ensure product quality. However, the screen mesh is a consumable item, susceptible to damage from raw material corrosion, wear, and impacts. If it breaks during production, it not only disrupts production plans but also wastes raw materials. Furthermore, failure to promptly detect material blockages can lead to excessive material weight causing the screen to rupture, resulting in severe material defects requiring rework.

[0003] Currently, in actual production processes, the detection of defects such as screen breakage and material blockage mainly relies on production personnel's subjective visual inspection and tension testing of the screen's outer surface. This method is heavily influenced by the subjective judgment of the production personnel and cannot promptly identify material blockage and screen damage, leading to increased labor costs. Common methods include using level switches, which only detect material level changes when the screen material reaches the switch's position, failing to monitor material level changes in real time. Furthermore, these switches are prone to wear and tear from contact with materials, potentially generating metallic foreign objects. Utility Model Content
