Description

Technical Field

[0001] This invention relates to the field of rare earth filtration, and more particularly to a magnetic rare earth filtration device for rare earth processing. Background Technology

[0002] Rare earth elements are a collective term for seventeen metallic elements, including the lanthanides, scandium, and yttrium, in the periodic table. Most rare earth elements exist in nature as rare earth ores and require complex smelting and extraction processes to be used. Because adding rare earth metals to alloys can significantly improve performance, they are widely used, especially in major industrial fields such as military, metallurgy, petrochemicals, and new energy. Therefore, rare earth elements are also known as "industrial vitamins." Furthermore, as an important foundation for new material manufacturing and a key resource related to the development of cutting-edge defense technologies, they are called "the earth of a thousand lives."

[0003] When rare earths are processed and produced, due to the low content of rare earth minerals and the presence of other impurities, filtration is necessary when extracting rare earths from ores to improve their purity and quality. This is of great significance for the application and processing of rare earths. Since most rare earth metals are paramagnetic, magnetic separation is a commonly used rare earth filtration method. This method utilizes magnetic materials or magnetic filter elements to adsorb and separate rare earths. Through the action of an external magnetic field, rare earth minerals are adsorbed onto the magnetic material, thereby achieving the separation and extraction of rare earth minerals. A common rare earth filtration method is to use pulleys to adsorb and filter rare earths. However, during the process of transporting rare earths, there may be a large quantity, which may lead to incomplete filtration. Furthermore, some rare earths may remain after feeding, requiring manual cleaning, resulting in low filtration efficiency. Summary of the Invention

[0008] Preferably, the bottom plate inside the feeding frame is stepped downwards from right to left, so that the magnetic rare earth poured into the feeding frame can be evenly fed onto the magnetic conveyor belt, thereby improving the subsequent adsorption and filtration effect.

[0014] (3) Beneficial effects 1. This invention utilizes a first scraper and a second scraper on the lower side of the upper and lower magnetic transmission belts to scrape the magnetic components adsorbed and filtered from the magnetic rare earth onto the first and second guide plates. While the magnetic rare earth is being transported via the magnetic transmission belt, a chain-linked trigger rod is activated, and under the action of a support spring, the first guide plate can vibrate up and down to prevent the filtered magnetic rare earth from remaining on the first guide plate, thereby improving the filtration effect of the magnetic rare earth and avoiding unnecessary losses.

[0015] 2. This invention enables the chain to be turned in conjunction with the trigger rod two, which in turn causes the feeding frame to vibrate back and forth, causing the magnetic rare earth in the feeding frame to be evenly shaken off onto the magnetic conveyor belt. At the same time, the chain is turned in conjunction with the actuating frame and wedge block, which causes the actuating frame to move back and forth on the magnetic conveyor belt, further spreading the magnetic rare earth on the magnetic conveyor belt, so that the magnetic components in the magnetic rare earth are fully adsorbed, thereby further improving the filtration effect.

[0016] 3. The present invention can also re-adsorb the magnetic rare earth after it has been filtered on the magnetic conveyor belt by setting up a magnetic frame and magnetic columns, so that any magnetic components that may remain can be completely adsorbed and filtered out. With the help of a dust baffle, the non-magnetic impurities that cannot be adsorbed will not affect the magnetic components after filtration, thereby improving the purity of magnetic and non-magnetic substances in the magnetic rare earth after filtration.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0028] Example 1: A magnetic rare earth filtration device for rare earth processing, such as... Figure 1 , Figure 2 and Figure 4As shown, it includes: a base frame 1, which serves as the mounting carrier for this device, and the base frame 1 is composed of a base plate and symmetrically arranged support plates; a transmission module 2, installed on the top of the base frame 1, the transmission module 2 being used for transporting magnetic rare earth elements; the transmission module 2 includes: a transmission frame 21, fixedly installed on the top of the base frame 1, and the transmission frame 21 is divided into two layers arranged in a stepped manner, with the right layer being higher than the left layer, each layer of the transmission frame 21 having a corresponding roller; and a magnetic transmission belt 22, consisting of two belts, one above the other, passing through the rollers. The shafts are installed on the upper and lower layers of the transmission frame 21 respectively. A servo motor 23 is fixedly installed on one side of the upper transmission frame 21. The servo motor 23 is connected to one of the rollers on the transmission frame 21 via a coupling. The rollers on the upper and lower layers are connected by belts. Two U-shaped baffles 3 are provided and fixedly installed on the top left side of the upper and lower transmission frames 21 respectively. A first scraper 4 is fixedly installed on the lower side of the upper transmission frame 21, and the first scraper 4 is adapted to and contacts the upper magnetic transmission belt 22. A second... A scraper 41 is mounted on the lower side of the lower transmission frame 21 via an elastic element, and the second scraper 41 is adapted to and contacts the lower magnetic transmission belt 22; a first guide plate 5 is rotatably mounted on the lower end of the first scraper 41; a support spring 51 is disposed between the first guide plate 5 and the transmission frame 21, and the support spring 51 is used to adapt to the first guide plate 5 and keep it in an inclined state; a second guide plate 6 is fixedly mounted on the lower side of the lower transmission frame 21, and the second guide plate 6 does not contact the magnetic transmission belt 22 and is used to adapt to the first guide plate 41. The second scraper 41 and the second guide plate 6 are inclined and located below the first guide plate 5. By pouring magnetic rare earth into the magnetic transmission belt 22, the magnetic transmission belt 22 will screen and filter out the magnetic components in the magnetic rare earth. The first scraper 4 and the second scraper 41 will scrape off the adsorbed magnetic components. After scraping off, the magnetic components will fall onto the first guide plate 5 and the second guide plate 6. Finally, the first guide plate 5 and the second guide plate 6 can be shaken to collect the components and reduce the amount of magnetic components remaining on the first guide plate 5 and the second guide plate 6, thereby avoiding unnecessary losses.

[0029] like Figure 1 and Figure 2As shown, it also includes a toggle chain 7 and a trigger rod 8. The toggle chain 7 has two parts, which are symmetrically fixed to the surface of the upper magnetic transmission belt 22. The toggle chain 7 has a plurality of symmetrical protrusions evenly arranged on it. The toggle chain 7 can move synchronously with the magnetic transmission belt 22. The trigger rod 8 is fixedly installed on the front and rear sides of the middle of the first guide plate 5. The trigger rod 8 is used to adapt to the toggle chain 7. When the magnetic transmission belt 22 is driven to move by the servo motor 23, the magnetic transmission belt 22 drives the toggle chain 7 to move together. The protrusions on the toggle chain 7 press against the trigger rod 8, causing the trigger rod 8 to move the first guide plate 5 downward. With the restoring force of the support spring 51, the first guide plate 5 automatically vibrates around the pivot on the first scraper 4.

[0030] Initially, the magnetic rare earth elements to be filtered are poured onto the upper magnetic conveyor belt 22. Since the magnetic conveyor belt 22 is magnetic, it adsorbs the magnetic components of the rare earth elements, causing them to adhere to its surface. Non-magnetic components remain on the belt. Then, the servo motor 23 is activated, synchronously driving the upper and lower magnetic conveyor belts 22 via a coupling. This causes the magnetic rare earth elements to be transported from right to left on the upper magnetic conveyor belt. Belt 22 will also drive the actuating chain 7 to move together. When the magnetic rare earth falls from the upper magnetic conveyor belt 22, the unadsorbed components inside the magnetic rare earth will fall onto the lower magnetic conveyor belt 22. The magnetic rare earth components scattered on the lower magnetic conveyor belt 22 will be further adsorbed and screened. The magnetic components adsorbed on the upper magnetic conveyor belt 22 will continue to be transported until the magnetic components on the upper magnetic conveyor belt 22 are transported to the first scraper 4. After the first scraper 4 contacts the upper magnetic conveyor belt 22, the magnetic components on it will be activated. The component is scraped onto the first guide plate 5. At this time, the actuating chain 7, which moves with the upper magnetic transmission belt 22, will briefly press against the trigger rod 8. The pressed trigger rod 8 will drive the first guide plate 5 to move downward. The lowered first guide plate 5 rotates around its axis and flips downward against the elastic force of the support spring 51. When the actuating chain 7 briefly stops pressing against the trigger rod 8, the first guide plate 5 will be pulled up and flipped under the elastic force of the support spring 51. Thus, by intermittently pressing the trigger rod 8 with the actuating chain 7, the first scraper 4 can dilute the component. As the rare earth magnetic components are scraped onto the first guide plate 5, the first guide plate 5 can intermittently shake up and down, thereby shaking the rare earth magnetic components that have fallen onto the first guide plate 5 onto the second guide plate 6. At the same time, the magnetic components remaining in the magnetic rare earth that fall onto the lower magnetic conveyor belt 22 will continue to be attracted and move with the lower magnetic conveyor belt 22 to the second scraper 41. Similarly, they are scraped off by the second scraper 41 onto the second guide plate 6 and gather with the magnetic components that have fallen from the first guide plate 5. Finally, they are concentrated and slide down the second guide plate 6 for collection by the user.

[0031] Example 2: Based on Example 1, such as Figures 1-3As shown, it also includes a feeding assembly 9, which includes: a bracket 91, symmetrically fixedly installed on the right side of the upper transmission frame 21, with guide rods provided between the brackets 91; a feeding frame 92, slidably installed on the brackets 91 via the guide rods, with a discharge port on the left side of the feeding frame 92, and a spring between the brackets 91 and the feeding frame 92; and a second trigger rod 93, fixedly installed on the bottom side of the feeding frame 92, with the second trigger rods 93 staggered and used to adapt to the dial. The moving chain 7, through the cooperation of two actuating chains 7, presses against the trigger rod 93, causing the feeding frame 92 to swing left and right on the support 91 against the spring force, thereby uniformly feeding the magnetic rare earth. The bottom plate inside the feeding frame 92 is stepped downward from right to left, so that the magnetic rare earth poured into the feeding frame 92 can be evenly fed onto the magnetic conveyor belt 22, so that the magnetic rare earth can be evenly spread on the magnetic conveyor belt 22, improving the subsequent adsorption and filtration effect.

[0032] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a leveling assembly 10, which includes: a cover plate 101, with an opening in the middle of the upper U-shaped baffle 3, the cover plate 101 being installed on the U-shaped baffle 3 through the opening, and the cover plate 101 having two through-holes; two clamping frames 102, which are symmetrically slidably installed on the lower side of the cover plate 101 through the through-holes, the top of the clamping frames 102 penetrating through the cover plate 101, and each clamping frame 102 having a slot at its lower end; two actuating frames 103, which are symmetrically installed on the lower ends of the two clamping frames 102 through the slots, and the two actuating frames 103 are connected as a whole by a connecting rod, the lower end of each actuating frame 103 having multiple actuating rods, and the actuating rods on the actuating frame 103 contacting the upper magnetic transmission belt 22; and two wedges 104, which are respectively fixedly installed. Installed on one non-adjacent side of each of the actuating frames 103, the actuating chains 7 on both sides press against the corresponding wedges 104, causing the wedges 104 to drive the actuating frames 103 to slide back and forth on the clamping frame 102. This causes the actuating rods on the actuating frames 103 to move the magnetic rare earth elements back and forth, making the magnetic rare earth elements more evenly spread on the magnetic conveyor belt 22 and preventing the magnetic rare earth elements from clumping together and affecting the filtration effect. The actuating frames 103 and the clamping frame 102 are slidably and detachably connected. The actuating frames 103 can be easily installed and removed from the corresponding clamping frame 102, making the actuating frames 103 better adaptable to magnetic rare earth elements with different properties. By installing actuating frames 103 at different intervals, the actuating rods on them can move the magnetic rare earth elements on the magnetic conveyor belt 22 more evenly, expanding the range of applications of the device for magnetic rare earth elements.

[0033] like Figure 1 , Figure 6 and Figure 7 As shown, the leveling assembly 10 further includes: locking blocks 105, two of which are symmetrically arranged and slidably mounted on the cover plate 101. A spring is provided between the locking blocks 105 and the cover plate 101. The locking blocks 105 are used to stably mount the clamping frame 102 on the cover plate 101. The clamping frame 102 has a slot at the top. One end of the locking block 105 is inserted into the slot, and the other end of the locking block 105 is an inclined block. Unlocking frame 106 is slidably mounted on the cover plate 101. Both the front and rear ends of the unlocking frame 106 are inclined blocks. The unlocking frame 106 is used to fit and press the corresponding locking blocks 105 so as to remove the clamping frame 102 and the actuating frame 103 from the cover plate 101 for easy maintenance of the clamping frame 102 and the actuating frame 103.

[0034] When feeding magnetic rare earth, the magnetic rare earth can be poured into the feeding frame 92 first. When the servo motor 23 is started to drive the magnetic conveyor belt 22 to start transporting, the magnetic conveyor belt 22 will synchronously drive the actuating chain 7 to move. When the actuating chain 7 on the front side presses against the corresponding trigger rod 93, the trigger rod 93 on the front side, after being pressed, will drive the feeding frame 92 to move backward. When the actuating chain 7 on the rear side presses against the corresponding trigger rod 93, the trigger rod 93 on the rear side, after being pressed, will drive the feeding frame 92 to move forward. Thus, through the two symmetrical actuating chains 7, the trigger rods 93 on the same side will be pressed in sequence, so that the feeding frame 92 can overcome the elastic force of the spring and shake back and forth, and the magnetic rare earth poured on it will be evenly shaken down onto the upper magnetic conveyor belt 22. When the magnetic rare earth shaken onto the upper magnetic conveyor belt 22 is transported to the left, the actuating chains 7 on the front and rear sides will also press against the corresponding trigger rods 93. On the corresponding wedge 104, the wedge 104, when squeezed, will drive the actuating frame 103 to reciprocate back and forth, so that the actuating frame 103 can move back and forth on the surface of the upper magnetic transmission belt 22, thereby allowing the transported materials to be further evenly distributed by the actuating frame 103, preventing the accumulation of magnetic rare earth elements and affecting the filtration effect. When the actuating frame 103 needs to be cleaned or maintained, by lifting the cover plate 101 from the upper U-shaped baffle 3, the cover plate 101 will drive the clamping frame 102 and the actuating frame 103 to move upward and separate from the upper U-shaped baffle 3. At this time, by pushing the unlocking frame 106, the unlocking frame 106 will be pressed against the locking block 105 by the inclined blocks at both ends, so that the locking block 105 is squeezed and overcomes the elastic force of the spring and slides and is no longer stuck on the clamping frame 102. Then the clamping frame 102 is removed from the cover plate 101 for subsequent cleaning or replacement of the clamping frame 102 and the actuating frame 103.

[0035] Example 3: Based on Example 2, such as Figure 1 and Figure 8As shown, it also includes an adsorption component 11, which includes: a magnetic frame 111, fixedly installed on the left side of the lower transmission frame 21; and multiple magnetic columns 112, which are fixedly arranged on the magnetic frame 111. The magnetic columns 112 are located at the discharge port of the lower magnetic transmission belt 22. The magnetic frame 111 and the magnetic columns 112 are used to adsorb any magnetic fractions that may remain in the magnetic rare earth, further improving the purity of the filtration and avoiding the waste of other useful components in the rare earth.

[0036] like Figure 1 , Figure 5 and Figure 8 As shown, it also includes a shielding assembly 12, which includes: a dust baffle 121, which is slidably installed on the bottom left side of the base frame 1, and the dust baffle 121 is used to block useless impurities in the filtered magnetic rare earth, preventing impurities from mixing back into the filtered magnetic rare earth; a reset spring 122, which is disposed between the dust baffle 121 and the base frame 1; and a linkage rod 123, which has two symmetrical rods that are respectively fixedly connected to the lower end of the first guide plate 5, and the linkage rod 123 is used to link and lift the dust baffle 121, and cooperate with the reset spring 122 to make the dust baffle 121 shake up and down.

[0037] After the magnetic rare earth elements on the lower magnetic conveyor belt 22 are adsorbed and filtered again, a small amount of magnetic components will inevitably remain mixed in and fall from the left side of the lower magnetic conveyor belt 22. Upon falling, these components will come into contact with the magnetic frame 111 and magnetic column 112. Under the adsorption of the magnetic frame 111 and magnetic column 112, the magnetic components in the magnetic rare earth elements will be further adsorbed, thus completing the thorough filtration of the magnetic rare earth elements. Non-magnetic impurities or sand will slide off the magnetic frame 111 and magnetic column 112, allowing users to collect and process them using containers. When non-magnetic impurities or sand fall, they will stir up dust. The dust will be blocked by the dust baffle 121, preventing the dust from reaching the right side of the dust baffle 121 and thus affecting the filtered magnetic rare earth components. Furthermore, the continuously shaking first guide plate 5 will drive the linkage rod 123 to shake up and down synchronously. Finally, under the action of the linkage rod 123, the dust baffle 121 will shake up and down, thus shaking the non-magnetic impurities or sand blocked by the dust baffle 121 into the container, reducing the workload of cleaning the dust baffle 121 later.

[0038] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
