Magnetic separator and iron separation process applying same

Abstract

The invention relates to a magnetic separator which comprises a magnetic separation box and a roller, the roller is located in the magnetic separation box, the two ends of the roller are fixedly connected with connecting shafts correspondingly, the two connecting shafts are rotationally connected with the inner wall of the magnetic separation box correspondingly, and the upper surface of the magnetic separation box is fixedly connected with two first supporting plates; the two first supporting plates are arranged at the two ends of the magnetic separation box in the length direction correspondingly, and a water spraying pipe is connected between the two first supporting plates. Two second supporting plates are fixedly connected to the upper surface of the magnetic separation box, first mounting grooves are formed in the side walls, close to the roller, of the two second supporting plates, first mounting blocks are arranged at the sides, close to the roller, of the second supporting plates, and the two ends of each first mounting block are located in the corresponding first mounting grooves correspondingly; a first scraper is fixedly connected to the side, close to the roller, of the first mounting block, and a rubber plate is connected to the side, close to the roller, of the first scraper and makes contact with the outer wall of the roller. The magnetic separator has the effect of fully scraping iron fine powder on the roller of the magnetic separator.

Description

technical field [0001] The present application relates to the technical field of iron concentrate powder purification equipment, in particular to a magnetic separator and an iron selection process using the magnetic separator. Background technique [0002] Magnetic separator is one of the most widely used and highly versatile models in the industry, and is suitable for the separation of substances with magnetic differences. Magnetic separators are widely used in mining, timber, kiln, chemical, food and other industries. [0003] The Chinese utility model patent that publication number is CN206793894U discloses a kind of magnetic separator water spray unloading device, comprises collection tank and water spray pipe, and collection tank is located at the below of magnetic separator drum, and water spray pipe is on the magnetic separator drum. The top of the drum is parallel to the central axis of the drum, and the angle between the connecting line between the central axis of ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there is a problem that the concentrated ore sticking to the drum of the washing magnetic separator by spraying water through the water spray pipe is not effective. If the water flow is too small, the concentrated ore on the drum is not easy to be washed off. defect
