Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a material discharging protection device for a magnetic separator. Background Art

[0002] A magnetic separator is a device that uses magnetism to separate magnetic and non-magnetic ores. Its working principle is based on magnetic differences, and magnetic minerals and non-magnetic minerals are separated by the action of a magnetic field. A magnetic separator is mainly composed of a magnetic system, a feeding device, a discharging device, and a transmission device, among which the magnetic system is the core part, and a strong magnetic field is usually generated by a permanent magnet or an electromagnet. The feeding device is used to input the material to be processed into the magnetic separator, and the discharging device is used to separate the material after magnetic separation from the non-magnetic material. Magnetic separators are widely used in ore beneficiation, waste treatment, metal recycling and other fields. They can separate metal minerals such as iron ore and manganese ore, or remove iron-containing impurities and harmful substances.

[0003] During the normal operation of the magnetic separator, its drum will inevitably bring up a certain amount of concentrate, which needs to be discharged by spraying water through the magnetic separator to prevent the concentrate from entering the tailings and causing metal loss. However, in the actual application process, it was found that due to the tailings treatment capacity of the high-efficiency concentrator, the clarification effect of the flocculant, and the mixing of debris (leaves, sawdust, etc.) into the water, the water quality of on-site production water cannot be effectively guaranteed. Floating objects (leaves, sawdust) are often mixed in the water supply, resulting in frequent siltation of the magnetic separator discharge water, causing the drum belt to carry goods, resulting in metal loss, and the loss of iron concentrate affects financial benefits. At the same time, in view of the siltation of the discharge water, on-site employees need to frequently dredge and handle it, which brings greater labor intensity to the employees. Therefore, we propose a magnetic separator discharge protection device. Utility Model Content
