Iron powder impurity removal device

Abstract

The invention discloses an iron powder impurity removal device, which comprises a transmission device, a strong magnet, a scraper device and a collection box. A circular magnetic block is arranged onthe outer side of a driven wheel in a coating manner. The collection box is located below the driven wheel. The scraper device is located on the left side of the driven wheel, and includes a fixed block, a locking rod, a support rod, a sleeve, a compression spring and a scraper. The fixed block is installed on the collection box. One end of the support rod is rotationally installed on the fixed block and is locked and fixed by the locking rod, and the sleeve is fixedly installed at the other end of the support rod. The middle part of the scraper is arranged in the sleeve in an up-down slidingmanner, and the upper end is located outside the sleeve and holds a transmission belt. The compression spring sleeves the scraper, with one end in contact with a support frame and the other end in contact with the upper part of the scraper and in a compressed state. The strong magnet is located between the driven wheel and the scraper device and on the inner side of the transmission belt. The ironpowder impurity removal device has a simple structure, and can scrape iron powder without damaging the transmission belt.

Description

technical field [0001] The invention relates to the field of impurity removal, in particular to an iron powder impurity removal device. Background technique [0002] Dense medium iron powder is an energy-saving and consumption-reducing product in the coal preparation industry. The quality of the medium directly affects the quality of clean coal and the cost of coal preparation. Most of the low-quality media powder in the market today, some coal preparation plants ignore the amount of heavy media, often resulting in large media consumption, directly resulting in losses of several million yuan each year. [0003] In the production process, iron powder often contains some impurities. The traditional method of removing impurities mainly uses magnets for adsorption, but the iron powder after adsorption is often retained on the transmission belt, which is difficult to clean. Manual cleaning will reduce production efficiency and clean up. Not clean, some mechanical cleaning method...

Most of the low-quality medium powder in the market today, some coal preparation plants ignore the amount of heavy medium, often resulting in large consumption of medium, directly causing losses of several million yuan every year

[0003] In the production process, iron powder often contains some impurities. The traditional method of removing impurities mainly uses magnets for adsorption, but the iron powder after adsorption is often retained on the transmission belt, which is difficult to clean. Manual cleaning will reduce production efficiency and clean up. Not clean, some mechanical cleaning methods can easily cause damage to the transmission belt
