[0002] With the large-scale popularization of electric vehicles and electrochemical energy storage, the market demand for lithium iron phosphate has increased dramatically. In order to continuously improve the electrochemical and safety performance of batteries, the requirements for the magnetic metal foreign matter index of lithium iron phosphate positive electrode materials are becoming increasingly stringent. Magnetic metal foreign matter will precipitate on the negative electrode side of the battery during the battery charging and discharging process and form a risk of metal single substance piercing the diaphragm, posing a great hidden danger to battery safety.

[0003] Iron phosphate production equipment often needs to introduce fresh air filtration equipment, which is generally equipped with fresh air filters. Due to the poor environment of the production workshop, the production equipment introduces fresh air filtration equipment to filter the metal dust and non-metallic dust in the workshop through the filter cotton of the fresh air filter. However, due to the large amount of foreign dust, the filter cotton often needs to be replaced frequently. However, if the filter cotton is replaced frequently, on the one hand, the production equipment needs to be shut down, and on the other hand, the labor intensity of the workshop personnel will be increased.
