Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a cleaning device for the magnetic rollers of a wet permanent magnet drum magnetic separator. Background Technology

[0002] In mineral processing plants, magnetic separators are commonly used mineral separation equipment, with the magnetic roller as its core component. Traditionally, magnetic separators primarily use water flushing during ore unloading, employing high-pressure water jets to wash away mineral particles adsorbed on the roller surface. However, this water flushing method has the following problems:

[0003] 1. Water flushing requires a large amount of water, which increases production costs and results in significant water waste;

[0004] 2. The water flushing effect is greatly affected by water quality and water pressure. When the water pressure is insufficient or the water quality is poor, the ore unloading effect is not good, and ore particles are likely to remain.

[0005] To address this, we propose a cleaning device for the magnetic rollers of a wet permanent magnet drum magnetic separator. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a cleaning device for the magnetic rollers of a wet permanent magnet drum magnetic separator. This invention solves the problems of water flushing requiring large amounts of water, increasing production costs, and causing significant water waste. Furthermore, the flushing effect is greatly affected by water quality and pressure; insufficient water pressure or poor water quality leads to poor ore unloading and the potential for mineral particle residue.

[0007] This utility model discloses a cleaning device for a wet permanent magnet drum magnetic separator, comprising a support frame, a material collection trough in the middle of the support frame, a magnetic roller above the material collection trough, a motor drive assembly fixedly installed on one side of the support frame and the output end of the motor drive assembly fixedly connected to the magnetic roller, first support plates at both ends of the support frame on one side of the magnetic roller, a shaft inserted into the middle of the two first support plates, a scraper between the two first support plates, a second support plate on the side of the first support plate away from the magnetic roller, water pipes inserted into the two second support plates, and multiple high-pressure nozzles arranged at equal intervals on the side of the water pipes near the magnetic roller.

[0008] In the above scheme, the height of the water pipe cross-section is lower than the height of the scraper cross-section.

[0009] In the above scheme, the support frame is provided with a fixed plate below the first support plate, a threaded rod is inserted into the middle of the fixed plate, the threaded rod is fixedly connected to the connecting block, both ends of the shaft are fixedly connected to the movable block, and the connecting block and the movable block are fixedly connected by a spring.

[0013] In the above scheme, the water inlet end of the water pipe is equipped with a water pressure regulating valve.

[0014] The advantages and beneficial effects of this utility model are as follows: This utility model provides a cleaning device for the magnetic roller of a wet permanent magnet drum magnetic separator. When the magnetic roller is working, the scraper can scrape off the gravel adhering to the surface of the magnetic roller. A water inlet device can be connected to the water pipe, and the water entering the water pipe is sprayed out through a high-pressure nozzle.
