[0002] The magnetic separator in the coal preparation plant is responsible for the recovery of magnetite powder in the dilute medium. Overflow regulation is the key link in controlling the loss of the medium. When the magnetic separator forms a stable overflow, it can reach its best working state. The main function of overflow regulation is to ensure continuous and appropriate liquid flow at the overflow port by adjusting the liquid level in the machine after reaching the best setting of the magnetic separator, so as to improve the magnetic separation efficiency of the magnetic separator.

[0003] In the prior art, the overflow regulation of the magnetic separator is mainly achieved by changing the position of the ceramic cover plate of the bottom flow port. When the overflow of the magnetic separator is large or small, the staff needs to use a long wooden stick to pry the ceramic cover plate, and change the size of the bottom flow port by changing the position of the ceramic cover plate relative to the bottom flow port. Since the ceramic cover plate is located in the coal sludge water during normal production and is not easy to observe, the staff can only achieve the goal through multiple adjustments based on experience. In the process of adjusting the size of the overflow, the staff needs to be close to the drum of the magnetic separator, which poses certain safety hazards; and the feed amount of the magnetic separator is constantly changing, requiring the bottom and overflow flow ratio to be adjusted at any time. If the overflow is not adjusted in time, the loss of magnetite powder will increase.

[0004] Therefore, the prior art needs to be further developed and improved. Utility Model Content
