Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing, in particular to a magnetic separation device for ore dressing. Background Art

[0002] Mineral magnetic separation is a mineral separation method that separates magnetic ores from non-magnetic ores in minerals through magnetic separation equipment. Existing magnetic separation devices for mineral separation use magnetic force to affect the movement state of magnetic ore particles during magnetic separation to separate magnetic ore particles from non-magnetic ore particles.

[0003] The publication number in the existing public technology is: CN214974817U. A magnetic separation device for ore dressing includes a shell, a magnetic separation mechanism and a holding mechanism. The left side of the inner wall of the shell is fixedly connected to the bottom of the workbench, the top of the workbench is provided with a first conveyor platform, and the left side of the top of the shell is embedded with a feed port; the magnetic separation mechanism includes an electromagnetic device, and the electromagnetic device is fixedly connected to the right side of the inner cavity of the second conveyor platform. The utility model has a reasonable structure. By starting the first conveyor platform, the ore is transported to the right on the surface of the first conveyor belt. At this time, the second conveyor platform and the electromagnetic device are started. The electromagnetic device generates magnetic force with a magnetic suction function. The non-magnetic ore on the right side of the first conveyor platform falls into the inner cavity of the first holding bucket, and the magnetic ore is adsorbed on the surface of the second conveyor belt by the electromagnetic device. The second conveyor belt drives the adsorbed ore to move to the right side of the second conveyor platform. At this time, the magnetic force of the electromagnetic device is reduced, and the ore falls off from the outer wall of the second conveyor belt and falls into the second holding bucket, realizing the magnetic separation of the ore.

[0004] However, the above patent still has certain disadvantages when used: the overall magnetic separation batch is small during magnetic separation, and there is stacking of magnetic ore particles and non-magnetic ore particles. When the magnetic ore particles are changed in motion state by magnetic attraction, the magnetic ore is easy to carry non-magnetic ore, resulting in poor magnetic separation effect. Moreover, ore particles of various sizes are mixed with each other, and the smaller magnetic ore will be blocked by the larger non-magnetic ore, and thus cannot be effectively processed. At the same time, the magnetic material used for adsorption will attach a large number of magnetic particles due to adsorption, and the adsorbent is not removed in time, which can easily cause the subsequent magnetic adsorption effect to be greatly reduced, thereby affecting the overall magnetic separation effect. The overall use effect is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the utility model provides a magnetic separation device for mineral processing, which has the following beneficial effects:

[0020] (1) The utility model adopts a detection component, an electromagnet, and an adsorption plate. When it is actually used, the rotation of the drive shaft can drive the adsorption plate to continuously rotate above the mineral particles. At this time, the magnetic ore therein can be adsorbed by the operation of the electromagnet on its surface, and the adsorbed magnetic ore can be moved to the position just above the discharge port during rotation. At this time, the internal detection component will detect that the adsorption plate has moved to the specified position, and at this time, the specified electromagnet will be triggered to stop power supply and lose magnetism, so that the adsorbed magnetic ore falls to the collection chamber at the bottom due to its own weight for storage, which is convenient for subsequent processing. The intermittent adsorption operation can avoid excessive adsorption of the electromagnet, which will lead to poor subsequent adsorption effect, thereby affecting the collection operation of the magnetic mineral, and has the advantage of timely removal.

[0021] (2) The utility model adopts a vibrator and a screening disk. During operation, personnel can add the mineral particles required for magnetic separation into the inner position of the magnetic separation cylinder through the feed port. At this time, the falling mineral particles will fall on the top screening disk. At this time, the operation of the external vibrator can vibrate the entire cylinder, thereby driving the mineral particles on the surface of the screening disk to vibrate, thereby increasing the contact effect between the electromagnet and the mineral particles at different positions. In addition, multiple sets of screening disks are arranged inside the device, so that the mineral particles can be screened multiple times, thereby improving the overall magnetic separation effect. The device has the advantages of multiple magnetic separation and good magnetic separation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In one embodiment, vibrators 2 are symmetrically installed in the middle of the two side surfaces of the magnetic separation cylinder 1. The vibrators 2 can vibrate the entire device, thereby processing the internal ore through vibration, increasing the contact effect between different ores and the adsorption plate 8, and thus improving the overall magnetic separation effect.

[0032] In one embodiment, a bottom plate 14 is welded at the bottom of the magnetic separation drum 1. The provision of the bottom plate 14 increases the ground contact area of ​​the device, thereby improving the overall operation stability.

[0033] In one embodiment, a feed port 5 is installed at one side of the top of the magnetic separation drum 1. The provision of the feed port 5 facilitates the addition of ore to be processed.

[0034] In one embodiment, a magnetic separation cavity 3 is provided between each pair of the screening discs 4, and the magnetic separation cavity 3 is provided for performing magnetic separation operation on the ore.

[0035] In one embodiment, the detection component 10 is composed of an infrared transmitter and an infrared receiver. By receiving the corresponding infrared signal, it can be determined whether the specified electromagnet 9 is within the area of ​​the discharge port 12, thereby facilitating the discharge operation of the magnetic ore.
