Description

Technical Field

[0001] This utility model relates to the field of magnetic separation equipment technology, specifically to a magnetic separation device for efficiently recovering monazite. Background Technology

[0002] In rare earth element-rich deposits, monazite may coexist with zircon in the ore. Because monazite is rich in rare earth elements, its recovery in zircon production has significant economic value. Monazite and zircon have different magnetic properties (monazite is a weakly magnetic mineral, while zircon is a non-magnetic mineral), and they are typically separated using magnetic separators. Therefore, a magnetic separator is needed to efficiently recover monazite from zircon to obtain high-value-added rare earth products and improve the economic benefits for enterprises.

[0003] The patent application with application number CN202022630096.3 discloses a multi-stage high-efficiency magnetic separator. It uses two sets of magnetic rollers to perform magnetic separation on materials and uses a stripping block to strip the magnetic materials on the two sets of magnetic rollers. Although it can improve production efficiency to a certain extent compared with single-roller magnetic separation and manual stripping, both waste (non-magnetic materials) and magnetic materials are collected through the guide block and the discharge port. That is, waste (non-magnetic materials) must be collected first and then magnetic materials must be collected. Therefore, the magnetic separator needs to be stopped during the collection process to prevent waste (non-magnetic materials) and magnetic materials from mixing, which will lead to a decrease in magnetic separation efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a magnetic separation device for efficient recovery of monazite, so as to solve the problem that the magnetic separation efficiency of existing multi-stage high-efficiency magnetic separators needs to be stopped when recovering magnetic materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency magnetic separator for recovering monazite includes a first roller, a second roller, a scraper, and a guide plate. The first roller and the second roller are arranged to rotate counterclockwise, with the second roller located below the first roller. A first magnetic system is fixedly installed inside the first roller, and a second magnetic system is fixedly installed inside the second roller, with the first magnetic system and the second magnetic system located on the same side. One end of the scraper abuts against the bottom of the first roller, and the other end of the scraper is close to the top of the second roller. The guide plate is disposed on one side of the scraper and biased towards the first magnetic system.

[0007] As an optional solution, both the first magnetic system and the second magnetic system are fan-shaped, with the first magnetic system and the second magnetic system respectively centered on the first roller and the second roller; the two ends of the first magnetic system and the second magnetic system extend to the first quadrant and the third quadrant of the coordinate system centered on their respective centers.

[0008] As an optional solution, the inner sidewalls of the first roller and the second roller are respectively attached to the outer circumferential surfaces of the first magnetic system and the second magnetic system.

[0009] As an optional solution, the lower end of the scraper is inclined toward the guide plate.

[0010] As an optional solution, the upper end of the scraper plate is provided with an abutment, the abutment including a scraper strip, a spring and a rubber sleeve; one end of the scraper strip is movably sleeved on the scraper plate, and both sides of the scraper strip are respectively connected to the scraper plate through the spring; the rubber sleeve is detachably sleeved on the other end of the scraper strip.

[0011] As an optional solution, the guide plate is arc-shaped and concentric with the first roller; the lower end of the guide plate is close to the scraper plate.

[0012] As an optional solution, the machine housing is also included, in which the first roller, the second roller, the scraper, and the guide plate are all disposed. The top of the machine housing is provided with a feed inlet located above the first magnetic system, and the bottom of the machine housing is provided with a collection box located below the second roller. The outer side walls of the machine housing are respectively provided with discharge ports communicating with the two sides of the collection box.

[0013] As an optional solution, a partition is provided in the middle of the collection box, which divides the collection box into magnetic compartments and non-magnetic compartments, with the upper end of the partition abutting against the bottom of the second roller.

[0014] By adopting the above technical solution, this utility model will have the following beneficial effects:

[0015] This invention provides a high-efficiency magnetic separation device for recovering monazite. A first magnetic system attracts magnetic materials, causing them to adhere to one side of a first roller and rotate upwards with it. When the magnetic materials rotate to the other side of the first roller, the attraction from the first magnetic system decreases, allowing heavier magnetic materials to fall freely under gravity, while lighter magnetic materials continue to rotate downwards with the first roller until they are scraped off by a scraper. Non-magnetic materials, unaffected by the first magnetic system, slide downwards along the first roller. A guide plate guides the non-magnetic materials towards the scraper, where they are blocked and fall onto a second roller for a second round of magnetic separation to separate any remaining magnetic materials. Finally, the completely separated magnetic and non-magnetic materials are collected on the sides of the first and second rollers, respectively.

[0016] Compared to existing multi-stage high-efficiency magnetic separators that require stopping the separator when recovering magnetic materials, this invention can collect magnetic and non-magnetic materials separately on both sides, thus preventing the mixing of magnetic and non-magnetic materials. Therefore, magnetic materials can be recovered without stopping the magnetic separation process, further improving magnetic efficiency. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please refer to Figure 1 In one embodiment of the high-efficiency magnetic separation device for recovering monazite according to this utility model, the high-efficiency magnetic separation device for recovering monazite includes a first roller 1, a second roller 2, a scraper 3, and a guide plate 4; the first roller 1 and the second roller 2 are arranged to rotate counterclockwise, and the second roller 2 is located directly below the first roller 1; a first magnetic system 11 capable of attracting magnetic objects is fixedly installed inside the first roller 1, and a second magnetic system 21 capable of attracting magnetic objects is fixedly installed inside the second roller 2; the first magnetic system 11 and the second magnetic system 21 are connected. The magnetic system 21 is located on the same side; the scraper 3 is fixedly installed, with one end abutting the bottom of the first roller 1 and the other end close to the top of the second roller 2; the guide plate 4 is fixedly installed on one side of the scraper 3 and biased towards the first magnetic system 11. Specifically, the guide plate 4 is arc-shaped and concentric with the first roller 1. The lower end of the guide plate 4 is close to the scraper 3. The guide plate 4 can guide the magnetic object falling from the first magnetic system 11 to move toward the scraper 3, so that the magnetic object falls between the scraper 3 and the guide plate 4 under the obstruction of the scraper 3.

[0026] In this embodiment, the mixture of magnetic material (monazite) and non-magnetic material (zircon) is lowered from the upper side of the first roller 1. When the material falls onto the first roller 1, the magnetic material is attracted by the first magnetic system 11 and adheres to one side of the first roller 1, rotating upwards with the first roller 1. When the magnetic material rotates to the other side of the first roller 1, the attraction force of the first magnetic system 11 decreases, allowing the heavier magnetic material to fall freely under the action of gravity, while the lighter magnetic material continues to rotate downwards with the first roller 1 until it is blocked by the scraper. 3. Scraping: When the material falls onto the first roller 1, the non-magnetic material is not attracted by the first magnetic system 11 and slides down the first roller 1 until it falls onto the guide plate 4. The guide plate 4 guides the non-magnetic material to move toward the scraper plate 3, so that the non-magnetic material is blocked by the scraper plate 3 and falls onto the second roller 2 for a second round of magnetic separation to separate the magnetic material remaining in the non-magnetic material. Finally, the completely separated magnetic material and non-magnetic material are collected on both sides of the first roller 1 and the second roller 2, respectively. In this way, the magnetic material can be recovered without stopping the magnetic separation operation.

[0027] Specifically, the first magnetic system 11 and the second magnetic system 21 are both fan-shaped with a central angle of 180°. The first magnetic system 11 and the second magnetic system 21 are respectively aligned with the center of the first roller 1 and the second roller 2, so that the magnetic material is more evenly adsorbed on the first roller 1 and the second roller 2. The two ends of the first magnetic system 11 and the second magnetic system 21 extend to the first quadrant and the third quadrant of the coordinate system centered on their respective centers. The upper ends of the first magnetic system 11 and the second magnetic system 21 extend to the first quadrant, so that the attraction force on the magnetic material is reduced and it is not easy for it to fall back instantly. The upper end of the second magnetic system 21 can attract the magnetic material accumulated on the scraper plate 3, making it easier for it to fall. The lower ends of the first magnetic system 11 and the second magnetic system 21 extend to the third quadrant, which can reduce the attraction force of the first magnetic system 11 on the magnetic material on the scraper plate 3 and prevent it from affecting the falling of the magnetic material.

[0028] Specifically, the inner sidewalls of the first roller 1 and the second roller 2 are respectively attached to the outer circumferential surfaces of the first magnetic system 11 and the second magnetic system 21, which can enhance the attraction of the magnetic objects on the first roller 1 and the second roller.

[0029] Specifically, the lower end of the scraper 3 is inclined toward the guide plate 4, which allows non-magnetic materials to slide down the scraper 3 after being blocked, thus smoothly transitioning to the second roller 2. This increases the contact time between the non-magnetic materials and the second roller 2, thereby better separating the residual magnetic materials in the non-magnetic materials.

[0030] like Figure 2The upper end of the scraper 3 is provided with an abutment 31 that is tightly attached to the surface of the first roller 1. The abutment 31 includes a scraper 311, a spring 312, and a rubber sleeve 313. One end of the scraper 311 is movably sleeved on the scraper 3, and both sides of the scraper 311 are connected to the scraper 3 via the spring 312. The rubber sleeve 313 is detachably sleeved on the other end of the scraper 311 by an interference fit. In use, the pushing force of the spring 312 can make the end of the rubber sleeve 313 away from the scraper 311 tightly attached to the surface of the first roller 1, so as to deeply scrape away the magnetic material on the surface of the first roller 1. The detachable design of the rubber sleeve 313 makes it convenient to replace it after wear.

[0031] Based on this, the high-efficiency magnetic separator for recovering monazite also includes a housing 5, in which the first roller 1, the second roller 2, the scraper 3, and the guide plate 4 are all disposed. A feed inlet 51 is opened at the top of the housing 5, located above the first magnetic system 11. One side of the feed inlet 51 has an inclined surface parallel to the scraper 3. A collection box 53 is provided at the bottom of the housing 5, located directly below the second roller 2. Magnetic and non-magnetic materials falling from the first roller 1 and the second roller 2 are collected on both sides of the collection box 53. The outer side walls of the housing 5 are respectively provided with discharge ports 52 that connect the two sides of the collection box 53. Magnetic and non-magnetic materials in the collection box 53 can be taken out through the two discharge ports 52.

[0032] Furthermore, a vertical partition 531 can be fixedly connected in the middle of the collection box 53. The partition 531 divides the collection box 53 into magnetic and non-magnetic compartments. The upper end of the partition 531 abuts against the bottom of the second roller 2, which can scrape off the lighter magnetic objects selected by the second round of magnetic selection. The aforementioned abutting member 31 can also be provided on the upper end of the partition 531 to improve the scraping effect.

[0033] The method of use or working principle of this utility model is as follows:

[0034] When monazite needs to be recovered during zircon production, a mixture of magnetic material (monazite) and non-magnetic material (zircon) is fed into the feed inlet 51. As the material falls onto the first roller 1, the magnetic material is attracted by the first magnetic system 11 and adheres to one side of the first roller 1, rotating upwards with it. When the magnetic material rotates to the other side of the first roller 1, the attraction of the first magnetic system 11 decreases, causing the heavier magnetic material to fall freely under gravity, while the lighter magnetic material continues to rotate downwards with the first roller 1 until it is scraped off by the scraper 3. Meanwhile, when the material falls onto the first roller 1, the non-magnetic material is not attracted by the first magnetic system 11 and slides downwards along the first roller 1 until it falls onto the guide plate 4. The guide plate 4 guides the non-magnetic material towards the scraper 3, causing the non-magnetic material to... After being blocked by the scraper 3, the non-magnetic material falls onto the second roller 2 for a second round of magnetic separation. During the second round of magnetic separation, the non-magnetic material is also not attracted by the first magnetic system 11 and slides down the second roller 2 until it falls into one side of the collection box 53. The magnetic material remaining in the non-magnetic material is attracted by the second magnetic system 21 and adsorbed onto one side of the second roller 2 and rotates upward with the first roller 1. When the magnetic material rotates to the other side of the first roller 1, the attraction of the second magnetic system 21 decreases, so the heavier magnetic material falls freely under the action of gravity, while the lighter magnetic material continues to rotate downward with the first roller 1 until it is scraped off by the scraper 3. Both fall into the other side of the collection box 53. Finally, the magnetic and non-magnetic materials on both sides of the collection box 53 can be removed through the two discharge ports 52.

[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
