Description

Technical Field

[0001] The invention belongs to the technical field of magnetic separation equipment, and in particular relates to a wet permanent magnetic flat plate magnetic separator for mining. Background Art

[0002] In the mining process, magnetic separation is widely used. There are many types of magnetic separators used in magnetic separation. According to the structure of the magnetic separator, it can be divided into drum magnetic separator, belt magnetic separator, roller magnetic separator, etc. It can also be divided into dry or wet magnetic separator. Magnetic separator is mainly used to separate weakly magnetic minerals, such as hematite, limonite, siderite, ilmenite, etc.

[0003] Chinese patent application CN118385030A discloses a multi-gradient micro-powder permanent magnetic dry magnetic separator, which adds a multi-gradient magnetic system on the basis of the existing magnetic separator to make the magnetic chain of the micro-powder magnetic ore fully flip during the separation process, so as to effectively remove impurities in the micro-powder magnetic ore, and by setting a swing drive and a swing rebounder, the magnetic repulsion of the swing drive is used to drive the multi-gradient magnetic system to rotate, and the rebound effect of the swing rebounder is used to reset the multi-gradient magnetic system, so as to achieve noise-free dynamic swing of the multi-gradient magnetic system, so that the selected magnetic material forms irregular magnetic chain flips on the surface of the magnetic drum, increases the number of magnetic chain flips, breaks the magnetic chain multiple times, and effectively avoids the formation of large magnetic agglomerations, thereby effectively removing impurities and dust in the magnetic chain to improve the magnetic separation effect, and realizes the swing of the multi-gradient magnetic system, so as to make the magnetic chain flip and effectively avoid the formation of large magnetic agglomerations, thereby effectively improving the magnetic separation effect.

[0004] The magnetic system of the existing wet strong magnetic separator is mainly composed of neodymium iron boron rare earth magnetic materials, which have a high magnetic induction intensity, and the magnetic field intensity on the surface of the magnetic plate is above 14000GS. The existing wet permanent magnetic flat plate strong magnetic separator generally adopts a belt structure, which has a large storage capacity, strong processing capacity, and small motor power. It is more energy-saving than conventional ordinary magnetic separators, and has a strong magnetic field force on magnetic minerals, thereby more effectively separating magnetic particles from the ore. The current wet permanent magnetic flat plate strong magnetic machine has a simple structure. However, the existing wet strong magnetic separator has poor magnetic mineral separation effect, and is mainly used in quartz sand purification and magnetic mineral removal. There is no substantial application in the field of mineral processing industry.

[0005] In addition, the beneficiation mechanism of the wet magnetic separator is to adsorb magnetic minerals in the ore within the magnetic field area of ​​the magnetic separator, and transport them to the magnetic field-free area through a belt carrier, and separate the magnetic particles through the impact of unloading water; from adsorption to separation, the magnetic particles form non-rolling "magnetic clusters" and "magnetic chains" under the action of a strong magnetic field, and are always adsorbed on the same position on the surface of the magnetic separator track. External cleaning water impact cannot disperse the "magnetic clusters" and "magnetic chains", and the non-magnetic minerals (impurities) wrapped in the "magnetic clusters" and "magnetic chains" cannot be separated and follow them into the concentrate area, further affecting the concentrate grade, resulting in the problem that the existing magnetic material beneficiation process requires more than two repeated sorting processes to select higher-grade concentrates. Summary of the invention

[0006] Based on the technical problems existing in the prior art, the present invention proposes a wet permanent magnetic flat plate magnetic separator for mining.

Preferably, a magnetic plate is installed inside the frame, the magnetic plate is located inside the conveyor belt, and the output ends of the first driven wheel, the second driven wheel and the driving wheel are connected to the same belt.

[0009] Preferably, the magnetic plate is divided into five areas, including a scanning area, a feeding area, a roughing area, a first selection area, and a second selection area. A cleaning structure is provided inside the frame, and the preferred cleaning structure includes two connecting rails, the connecting rails are fixedly connected to the frame, the inner wall of the connecting rails is slidably connected with a slide bar, and the ends of the two slide bars close to each other are both detachably connected with connecting rings.

[0016] 5. The present invention achieves the effect of conveniently cleaning the transmission belt by providing a cleaning structure, thereby preventing the conveyor belt from being severely aged after short-term use, which not only wastes resources but also increases costs. The device also achieves the effect of conveniently replacing the cleaning pad for cleaning the conveyor belt.

[0017] 6. The present invention achieves the goal of conveniently collecting the minerals after screening by the magnetic separator by setting up a collection structure, providing portability whether for reuse or destruction, and preventing the minerals after magnetic separation from being scattered on the ground and difficult to clean up.
