The permanent magnet drum magnetic separator is applicable to ore dressing in metallurgical mines and is used for separating fine-grained magnetic minerals. During the use of the permanent magnet drum magnetic separator, an ore distribution device is required for feeding ore.

[0003] The ore distribution device for a permanent magnet drum magnetic separator usually includes the following main structural parts: a feeding device: used to evenly distribute raw ore onto the surface of the drum of the magnetic separator. The feeding device usually includes a vibrating feeder or a belt feeder, etc.; a distributing trough: during the ore distribution process, the ore is evenly distributed around the drum, and when rotating in the drum, it maintains effective contact between the ore and the magnetic field; a permanent magnet system: the core part of the permanent magnet drum magnetic separator, usually composed of multiple permanent magnets, generating a high-intensity magnetic field for separating magnetic minerals; a drum: a cylindrical structure equipped with a permanent magnet system and a distributing trough. The drum can rotate or be fixed to enable effective separation of the ore in the magnetic field; a discharging device: used to collect the separated ore products and non-magnetic waste residues. The discharging device usually includes a waste residue discharge port and a product collection port.

[0004] During the process of distributing ore to a permanent magnet drum magnetic separator by the existing ore distribution device, it is easy to have a large amount of ore in the middle of the magnetic separator and a small amount of ore on both sides, resulting in poor uniformity of ore distribution. Therefore, in view of the above problems, a uniform ore distribution device for a permanent magnet drum magnetic separator is proposed. Summary of the Utility Model

The slider 11 slides in cooperation with the lead screw 9 through threads. A connecting block 12 is installed on the slider 11, and the flexible hose 4 is fixedly connected to the connecting block 12. A pipe groove 13 is opened on the top plate of the ore distribution bin 6, and the flexible hose 4 passes through the pipe groove 13.

A driving rod 23 is welded to the bottom side of one end of the driving plate 22. The other end of the driving plate 22 is a fan-shaped structure; during operation, in the process of distributing ore to the permanent magnet drum magnetic separator by the existing ore distribution device, it is easy to have a large amount of ore in the middle of the magnetic separator and a small amount of ore on both sides, resulting in poor uniformity of ore distribution. By operating the first motor 21, the driving plate 22 is driven to rotate. When the driving plate 22 rotates, the driving rod 23 on it will slide into one of the rod grooves 19 of the rotating disk 18, and at the same time, the driving rod 23 pushes the rotating disk 18 to rotate 120°.

The rotating disk 18 will drive the rotating shaft 15 to rotate 120°, and then make the rotating shaft 15 stationary. When the rotating shaft 15 is stationary, the hose 4 moves from left to right or from right to left. The hose 4 evenly scatters the ore on the distributing plate 16.

[0021] Working principle: In the process of ore distribution for the permanent magnet drum type magnetic separator by the existing ore distribution device, it is easy to have a large amount of ore in the middle of the magnetic separator and a small amount of ore on both sides, resulting in poor uniformity of ore distribution. Through the operation of the first motor 21, the driving plate 22 is driven to rotate. When the driving plate 22 rotates, the driving rod 23 on it will slide into a rod slot 19 of the rotating disk 18. At the same time, the driving rod 23 pushes the rotating disk 18 to rotate 120°. Then the driving rod 23 slides out of the rod slot 19, and the fan-shaped structure of the driving plate 22 will be tangent to one of the positioning plates 20. At this time, the rotating disk 18 is in a fixed state. The above is the movement track of the driving plate 22 rotating one circle, that is, the driving plate 22 rotating one circle will push the rotating disk 18 to rotate 120°, and then make the rotating disk 18 stationary; Meanwhile, the electromagnetic valve 5 is controlled to open through the control panel 2, and the ore in the storage bin 3 falls into the hose 4. Through the operation of the stepping motor 10, the stepping motor 10 drives the lead screw 9 to rotate reciprocally forward and backward. The lead screw 9 drives the slider 11 to move horizontally back and forth. The slider 11 drives the connecting block 12 to move horizontally back and forth. The connecting block 12 drives the hose 4 to move horizontally back and forth. That is, after the hose 4 moves from left to right, it moves from right to left again; When the driving plate 22 rotates one circle, it will push the rotating disk 18 to rotate 120°, and then make the rotating disk 18 stationary. The rotating disk 18 will drive the rotating shaft 15 to rotate 120°, and then make the rotating shaft 15 stationary. When the rotating shaft 15 is stationary, the hose 4 moves from left to right or from right to left. The hose 4 evenly scatters the ore on the distributing plate 16. Then the rotating shaft 15 rotates 120°. During the rotation of 120°, the ore on the distributing plate 16 flows out from the discharge hopper 17 and falls onto the magnetic separator, achieving uniform ore distribution and being beneficial to improving the uniformity of ore distribution.
