[0002] Metal cleaning agent is a chemical substance used for cleaning metal surfaces, mainly used for removing dirt, oxides, grease and other impurities on the surface of metal, which usually exists in the form of liquid or powder, and can be used by scrubbing, soaking, spraying, etc. However, in the production process of metal cleaning agent, raw materials may contain impurities or produce impurities during production, so that the filtering device can effectively remove these impurities to ensure the purity of the cleaning agent. Due to the long-term use of the filtering device, the impurities in the cleaning agent are easy to accumulate in the filtering device, which affects the filtering effect. Therefore, the cleaning device is needed to clean the impurities to prevent the filtering device from being blocked. However, when the filtering device is used, the impurities in the filtering device are moved by the cleaning device, so that the impurities move in the filtering device, which can prevent the impurities from blocking the filtering device. However, the impurities in the filtering device are continuously increasing during the continuous filtering of the cleaning agent, so that the impurities will accumulate and cover the surface of the filtering device, which will slow down the speed of the cleaning agent through the filtering device, affect the overall flow, and increase the time required for cleaning agent filtering.
