Description

Technical Field

[0001] The present application relates to the technical field of iron removal equipment, and in particular to a self-cleaning iron removal device. Background Art

[0002] With the development of new energy technology, battery technology is also advancing rapidly. At present, anhydrous iron phosphate powder, as a precursor of lithium iron phosphate, is usually used to prepare lithium iron phosphate positive electrode materials and is widely used in the field of lithium-ion batteries. However, anhydrous iron phosphate powder may be mixed with iron impurities during the preparation process, which has a great impact on the quality of lithium-ion batteries. Therefore, after the preparation of anhydrous iron phosphate powder is completed, it needs to be processed by secondary iron removal equipment.

[0003] The prior art discloses a device suitable for removing iron from powder, comprising: a shell having a feed port on the top and a discharge port on the bottom; a plurality of first partitions arranged in the shell at intervals along the vertical direction; support rods fixedly connected to each first partition respectively; a plurality of pairs of second partitions, one first partition corresponding to a pair of second partitions, a pair of second partitions being arranged below the corresponding first partitions, and a pair of second partitions not contacting each other; a plurality of pairs of support plates, a pair of second partitions corresponding to a pair of support plates, and one second partition corresponding to a support plate, a pair of support plates being arranged at the bottom of the corresponding pair of second partitions, the support plates and the corresponding second partitions, and the inner side walls at both ends of the shell arranged at intervals along its width direction form a receiving cavity; a plurality of magnets, at least one magnet being selectively arranged in each receiving cavity.

[0004] With regard to the above-mentioned related technologies, the powder material that needs to be de-ironized is put into the feed port and flows through the magnet to adsorb the iron impurities. During use, a certain amount of iron impurities will be attracted by the magnet. As the amount of attracted iron impurities gradually increases, there is a possibility that the iron impurities will fall back into the powder during the re-adsorption. Therefore, it is necessary to open the shell regularly to clean the magnet. The cleaning frequency of the iron impurities on the surface of the magnet is generally high, which increases the labor intensity of the staff. Utility Model Content
