Description

Technical Field

[0001] The utility model relates to the technical field of wheat processing, in particular to a secondary magnetic separator. Background Art

[0002] After wheat is ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods. After fermentation, it can be made into beer, alcohol, liquor or biomass fuel. Before wheat is ground into flour, since it contains more impurities, such as iron filings, iron wire and other foreign matter, these impurities need to be separated from the wheat through a secondary magnetic separator to ensure the purity of the wheat and improve the quality of the flour.

[0003] In the Chinese patent with publication number CN217120542U, a wheat magnetic separation and impurity removal device is disclosed. Through the setting of magnets, the magnets can absorb iron wires and iron filings. Under the cooperation of the translation mechanism, the box body and the guide rod, the translation mechanism can drive the box body to move left and right on the guide rod to discharge the wheat from the second outlet. After the wheat is discharged, the telescopic mechanism can drive the scraper to move downward so that the scraper is flush with the box body. The driving mechanism drives the scraper under the moving plate through the lead screw to scrape the iron wires and iron filings to the left side of the chassis. Through the setting of the top block, the baffle can be moved to the left. Push sideways so that the scraper can scrape the iron filings and iron wires from the box body and discharge them through the first outlet. When used, it can greatly improve the efficiency of separating wheat from impurities such as iron wires. However, during the use of the above-mentioned wheat magnetic separation and impurity removal device, when impurities such as iron filings or iron wires are on the top of the wheat, it is difficult to adsorb impurities such as iron filings or iron wires mixed in the wheat using the magnetic force of the magnet placed at the bottom of the box body, resulting in poor magnetic separation effect, reducing the quality of the screened wheat, affecting the overall quality of the wheat, and reducing the quality of wheat flour. Therefore, we propose a secondary magnetic separator. Utility Model Content
