Description

Technical Field

[0001] This invention relates to the field of magnetic separation equipment technology, specifically a pulsed multi-pole magnetic powder recovery separator. Background Technology

[0002] In the process of mineral resource development and utilization, with the continuous depletion of high-quality mineral resources, the demand for processing complex ores such as lean ores and fine-grained disseminated ores is increasing. Traditional magnetic separation equipment has certain limitations in recovering weakly magnetic minerals from these ores.

[0003] Conventional high-gradient magnetic separators have difficulty recovering fine-grained weakly magnetic minerals, which can easily lead to the loss of valuable weakly magnetic minerals.

[0004] In existing magnetic powder recycling machines, if the magnetic drum's adsorption force is too large, the magnetic powder scraping effect will be poor, resulting in a low magnetic powder recovery rate; if the magnetic drum's adsorption force is too small, the magnetic powder will fly out of the magnetic drum when it rotates at high speed, affecting the recycling effect.

[0005] The rotating cylinder of a permanent magnet drum separator requires the installation of a large number of strong magnets. When workers are fixing and installing multiple layers of strong magnets, the magnetic repulsion between the strong magnets requires the cooperation of multiple workers, which increases manufacturing costs and energy consumption. In addition, the magnetic entanglement phenomenon is more serious, which affects the separation effect.

[0006] Therefore, we made improvements and proposed a pulsed multi-pole magnetic powder recovery separator. Summary of the Invention

[0047] The present invention has the following beneficial effects:

[0048] The gradient and closed strong magnetic field network in the magnetic separation mechanism has a stronger adsorption force on magnetic materials of different particle sizes in the ore, especially fine particles. It can adsorb large magnetic materials and capture tiny magnetic powders, thereby improving the overall recovery rate.

[0049] The structural design of the magnetic separation zone and the unloading zone achieves a balance between secondary magnetic separation and efficient unloading. The magnetic material is naturally detached by utilizing the non-magnetic field characteristics of the unloading zone, avoiding the adhesion residue caused by the magnetic field residue during the scraping of material in traditional equipment. Electromagnetic components are added to the unloading zone, and intermittent power supply is achieved through segmented electric slip rings, so that the unsorted ore can still be subjected to secondary magnetic separation when the unloading zone enters the bottom of the frame, thereby improving the magnetic separation efficiency.

[0050] The spacer design and magnetic field gradient optimization of the strong magnetic component, combined with the water distribution pipe of the water washing mechanism, can effectively remove non-magnetic gangue adhering to the surface of magnetic materials and reduce the content of concentrate impurities caused by magnetic encapsulation.

[0051] Both the strong magnetic components and electromagnetic components adopt a modular assembly structure. Disassembly and assembly can be completed quickly by simply removing the front nut, reducing installation and maintenance costs.

[0052] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0090] The front bottom of the rubber scraper 24 is located on the outer wall of the fixed plate 19.

[0091] Several magnetic separation mechanisms 4 are coaxially and fixedly connected by a rotating shaft 30, and the rotating shaft 30 is fixedly connected through the rubber isolation sleeve 21;

[0092] One end of the rotating shaft 30 is connected to a drive motor via a belt and a flywheel, and the drive motor is located at the rear of the upper surface of the slag discharge base 2.

[0093] The other end of the rotating shaft 30 is equipped with a speed regulating mechanism.

[0097] Working principle of Embodiment 1 of the present invention:

[0098] The drive motor drives the magnetic separation mechanism 4 to rotate. The ore material is poured from the upper rear end of the magnetic separator frame 1 into the gap between the adjacent magnetic separation mechanisms 4 via the conveyor belt. The rotating magnetic separation mechanism 4 adsorbs the magnetic materials in the ore material onto the outer wall of the sealing plate 7 and the magnetic separation box 6 placed in the magnetic separation zone 9.

[0099] As the magnetic separation mechanism 4 rotates, the magnetic material gradually accumulates on the upper part of the side wall where the rubber scraper 24 and the outer wall of the magnetic separation mechanism 4 are attached. When the unloading area 10 rotates to the position of the rubber scraper 24, the magnetic material falls into the inner cavity of the rubber scraper 24 because there is no magnetic field in the unloading area 10.

[0100] At the same time, clean water is introduced into the main water pipe 31, and the clean water is flushed through the water distribution pipe 32 to flush the gap between the adjacent magnetic separation mechanism 4. The clean water flushes the magnetic material in the rubber scraper 24 and then flushes the magnetic material into the collection tank 3.

[0101] In addition, the ore after magnetic separation falls onto the bottom wall of the magnetic separator frame 1, and under the flushing of clean water, it enters the inner cavity of the slag discharge base 2 through the waste outlet, and is finally discharged from the front end of the slag discharge base 2.

The electromagnet 35 in the unloading area 10 is energized through the segmented electric slip ring. The rotating magnetic separation mechanism 4 adsorbs the magnetic materials in the ore onto the outer wall of the sealing plate 7 and the magnetic separation box 6.

[0121] Under the rotation of the magnetic separation mechanism 4, the magnetic material is enriched on the upper side wall of the rubber scraper plate 24. When the unloading area 10 rotates to the rubber scraper plate 24, the corresponding electromagnetic components 33 and electromagnets 35 are de-energized in sequence under the action of the segmented electric slip rings, and the adsorbed magnetic material falls into the rubber scraper plate 24.

[0122] At the same time, clean water is introduced into the main water pipe 31, and the clean water is flushed through the water distribution pipe 32 to flush the gap between the adjacent magnetic separation mechanism 4. The clean water flushes the magnetic material in the rubber scraper 24 and then flushes the magnetic material into the collection tank 3.

[0123] When the electromagnetic component 33 rotates with the magnetic separator 6 and passes the rubber scraper 24, it is energized under the action of the segmented electric slip ring, so that the unloading area 10 generates a magnetic field.

[0124] When the unloading zone 10 enters the bottom cavity of the magnetic separator frame 1, it can continue to perform magnetic separation and screening on the ore at the bottom of the magnetic separator frame 1, thereby improving the magnetic separation effect.
