[0035] When in use, the feed pipe 1 is connected to the raw material mill and the powder classifier, the raw material is transported in the feed pipe 1, falls onto the receiving plate 3 and then continues to be transported after sliding along the inclined receiving plate 3, while the iron blocks mixed in the raw material are adsorbed by the adsorption component 5 and remain on the receiving plate 3, so that the iron blocks in the raw material are separated; when the iron blocks need to be cleaned, the receiving plate 3 is driven to rotate and turn over by the first driving component 4, and then the iron blocks adsorbed on the receiving plate 3 are scraped off by the scraping component 6, and the scraped iron blocks fall into the mounting cover 2 for collection, and at this time, the other side of the receiving plate 3 continues to adsorb the iron blocks.
[0036] The device absorbs iron blocks mixed in the raw material by setting a receiving plate 3 and an adsorption component 5, realizes the raw material iron removal operation, and prevents the accumulation of iron blocks from affecting the normal operation of the raw material mill. In addition, the two receiving plates 3 are symmetrically arranged in an upper and lower staggered manner, so that the raw material can fully contact the receiving plates 3 when being transported through the feeding pipe 1 for the iron removal operation; the device is convenient for turning the receiving plate 3 over and scraping off the iron blocks adsorbed on the receiving plate 3 by setting a first driving component 4 and a scraping component 6, while the other side of the receiving plate 3 continues to adsorb iron blocks, without the need to stop the operation, thereby improving the convenience of use and ensuring continuous production operation.
