Description

Technical Field

[0001] This utility model relates to the field of rare earth waste treatment technology, specifically a rare earth waste extraction and impurity removal device. Background Technology

[0002] As research on rare earths deepens, they are increasingly being applied in high-tech industries. In the machinery field, the utilization rate of rare earths is constantly increasing. At the same time, the amount of rare earth waste generated in the production process is also increasing. Furthermore, the over-exploitation of rare earth resources has not only caused a great waste of resources but also caused serious environmental pollution. Therefore, it is necessary to recycle rare earth materials.

[0003] The existing Chinese utility model patent with publication number CN207308326U discloses a rare earth waste device, particularly a rapid screening and impurity removal device for rare earth waste. The technical problem this utility model aims to solve is to provide a rapid screening and impurity removal device for rare earth waste that can save and utilize rare earth waste, reduce waste, and minimize economic losses. To solve the above technical problem, this utility model provides such a rapid screening and impurity removal device for rare earth waste, including a base plate, a left side plate, a guide rod, a type 7 support rod, a cylinder, a connecting rod, a first electromagnet, a first spring, a collection box, a second spring, a placement plate, and a second electromagnet; the left side plate, cylinder, and type 7 support rod are connected to the top of the base plate from left to right by bolts. This utility model filters out large particulate impurities from the rare earth waste using a filter screen, uses a pusher plate to level the rare earth waste collected in the collection box, and uses a dust pump to remove dust from the protective cover.

[0004] The aforementioned screening and impurity removal device uses electromagnets to adsorb magnetic metals inside rare earth waste. However, this method cannot classify metals that are affected by magnetic force to varying degrees, and further classification is still required. In addition, the adsorption effect of electromagnets is limited. After a certain amount of material accumulates at the bottom of the electromagnet, the adsorption effect will weaken, and the material adsorbed at the bottom of the electromagnet needs to be transferred before the equipment can continue to operate. Utility Model Content

[0015] Beneficial effects

[0016] This invention provides a device for extracting and removing impurities from rare earth waste. Compared with the prior art, it has the following advantages:

[0017] (1) The rare earth waste extraction and impurity removal device uses electromagnets. The electromagnets and the receiving hoppers below are installed in groups at equal distances between the support frame. The electromagnets are located inside the conveyor belt, and the receiving hoppers are located below the conveyor belt. The overall height decreases sequentially from back to front. When the electromagnets are energized, they generate magnetic force, thereby adsorbing the components in the rare earth waste that can be affected by magnetism. By adjusting the magnitude of the magnetic force generated by multiple electromagnets to decrease sequentially from front to back, the components in the rare earth waste that can be affected by magnetism are sorted. The number of receiving hoppers is the same as the number of electromagnets, which can receive the material that falls after the magnetism weakens. The impurities after sorting are transported by setting up a separate conveyor belt under the receiving hopper, or the impurities are collected by placing a container under the receiving hopper for subsequent processing, so as to achieve the effect of sorting according to the strength of magnetism.

[0018] (2) The rare earth waste extraction and impurity removal device can limit the position of the bottom opening of the hopper through the limiting frame, so that the falling position of the rare earth waste is located between the baffles. The hopper receives a certain amount of rare earth waste, and then the drive motor drives the unloading shaft to rotate at a certain speed, so that the falling speed of the rare earth waste matches the speed of the conveyor belt, ensuring the thickness of the rare earth waste above the conveyor belt. When the conveyor belt moves the rare earth waste to the outside of the front support pipe, the magnetic tiles inside the support pipe can adsorb the components affected by magnetism, so that the components that can be attracted by the magnetic tiles continue to move backward with the conveyor belt to the bottom of the electromagnet, and are sorted by the electromagnet. In this way, the components that can be affected by magnetic force will fall directly into the receiving hopper below, so as to prevent the components from accumulating and affecting the impurity removal efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a rare earth waste extraction and impurity removal device, including a limiting frame 1, a hopper 11 fixedly installed at the top of the limiting frame 1, a discharge shaft 12 fixedly installed at the bottom of the hopper 11, a drive motor 13 fixedly installed on the outside of the hopper 11, the bottom end of the hopper 11 is an arc-shaped structure, and the arc-shaped structure at the bottom end of the hopper 11 contacts the outer edge of the discharge shaft 12, the left end of the discharge shaft 12 is fixedly connected to the rotating shaft of the drive motor 13, and the discharge shaft 12 and the hopper 11 form a rotatable connection, and the outer side of the discharge shaft 12 is provided with a ring-shaped distribution of protrusions.

[0026] Specifically, the limiting frame 1 can restrict the position of the bottom opening of the hopper 11, so that the falling position of the rare earth waste is between the baffles 225. The hopper 11 receives a certain amount of rare earth waste, and then the drive motor 13 drives the unloading shaft 12 to rotate at a certain speed, so that the falling speed of the rare earth waste matches the speed of the conveyor belt 223, ensuring the thickness of the rare earth waste above the conveyor belt 223. The model of the drive motor 13 is 1FT7036-5AK70-1FB2.

[0027] A cleaning mechanism 2 is installed below the limit frame 1.

[0028] The support frame 21 is located inside the limiting frame 1 and is used to support the conveying assembly 22 and the sorting assembly 23.

[0029] Specifically, the support frame 21 can limit the position of the conveyor belt 223 and the position of the electromagnet 231 and the receiving hopper 232 in the same group by limiting roller 221 and support roller 222, so as to ensure that magnetic impurities can fall into the corresponding receiving hopper 232 after the magnetism weakens.

[0030] The conveying assembly 22 is located inside the support frame 21 and is used to convey rare earth waste. The conveying assembly 22 includes a limiting roller 221 and a support roller 222 fixedly installed on one side of the support frame 21. A conveyor belt 223 is installed on the outer side of the limiting roller 221 and the support roller 222. The conveying assembly 22 also includes a drive motor 224 and a baffle 225 fixedly installed on one side of the support frame 21. There are three limiting rollers 221, which are installed on the rear side of the support frame 21. The support rollers 222 are installed at equal distances on one side of the support frame 21. The limiting rollers 221, the support rollers 222 and the support frame 21 are rotatably connected by bearings. The front end of the conveyor belt 223 is located outside the support tube 239. The baffle 225 is installed symmetrically on both sides of the conveyor belt 223, and the front end of the baffle 225 is provided with an arc-shaped structure. The bottom of the conveyor belt 223 is inclined.

[0031] Specifically, the limiting roller 221 can limit the shape of the conveyor belt 223 to ensure that the wrap angle between the conveyor belt 223 and the limiting roller 221 at one end of the drive motor 224 is greater than 120 degrees. The support roller 222 can support the conveyor belt 223 and prevent the conveyor belt 223 from deforming under the gravity of the rare earth waste. The conveyor belt 223 can drive the rare earth waste to move. The drive motor 224 is model YBX3-80M1-4-0.55KW. The drive motor 224 can drive the conveyor belt 223 to rotate through the limiting roller 221. The baffle 225 is set above the conveyor belt 223 and can limit the rare earth waste to the center of the conveyor belt 223 to prevent the rare earth waste from falling to the sides of the conveyor belt 223.

[0032] The sorting assembly 23 includes an electromagnet 231 fixedly installed on one side of the support frame 21, a receiving hopper 232 disposed below the electromagnet 231, and an inclined plate 233 fixedly installed at the front end of the support frame 21. The sorting assembly 23 also includes a connecting pipe 234 inserted through the front end of the support frame 21, a connecting shaft 235 inserted through the center of the connecting pipe 234, a connecting frame 236 fixedly installed on the outside of the connecting shaft 235, a limiting tube 237 fixedly installed on the outside of the connecting frame 236, a magnetic tile 238 fitted on the outside of the limiting tube 237, and a support tube 239 fixedly installed on one side of the limiting tube 237. The electromagnet 231 and the receiving hopper 232 are connected to the receiving hopper 232. Buckets 232 are installed in groups at equal intervals between support frames 21. Electromagnets 231 are located inside conveyor belts 223. The receiving buckets 232 are located below conveyor belts 223, and their overall height decreases sequentially backward. Connecting pipes 234 and support frames 21 form a rotating connection. Connecting frames 236 are installed at equal intervals on the outside of connecting shafts 235. The outer side of limiting pipes 237 is provided with grooves that fit into magnetic tiles 238. Magnetic tiles 238 are installed in groups of four in an "X" shape on the outside of limiting pipes 237, with the center of the limiting pipe 237 as the reference. There are four groups of magnetic tiles 238. The inner wall of support pipes 239 does not contact magnetic tiles 238 or limiting pipes 237.

[0033] Specifically, the electromagnet 231 is model MW22. When energized, the electromagnet 231 generates magnetic force, thereby attracting magnetically affected components in the rare earth waste. By adjusting the magnetic force generated by multiple electromagnets 231, decreasing sequentially from front to back, the magnetically affected components in the rare earth waste are sorted. The number of receiving hoppers 232 is the same as the number of electromagnets 231, and they are located directly below the corresponding electromagnets 231. They can catch the material falling after the magnetism weakens. Impurities are transported by a separate conveyor belt 223 installed below the receiving hopper 232, or impurities are collected by placing a container below the receiving hopper 232 for subsequent processing. The inclined plate 233 is tilted to guide the rare earth... Components in the waste that are not affected by magnetism slide forward. The connecting tube 234 can limit the position between the connecting shaft 235 and the support tube 239. The relative position between the limiting tube 237 and the support tube 239 is determined by the connecting bracket 236 on the outside of the connecting shaft 235. The magnetic tile 238 on the outside of the limiting tube 237 can be located at the turning point of the front end of the conveyor belt 223 and can adsorb components that can be affected by magnetism on the inside of the conveyor belt 223. The components that can be affected by magnetism can continue to move backward with the conveyor belt 223 under the drive of the conveyor belt 223 to the bottom of the electromagnet 231. The support tube 239 can limit the position of the front end of the conveyor belt 223. At the same time, all contents not described in detail in this specification are prior art known to those skilled in the art.

[0034] During operation, electromagnets 231 and receiving hoppers 232 are installed in groups, equidistant from each other, between support frames 21. Electromagnets 231 are located inside conveyor belts 223, and receiving hoppers 232 are located below conveyor belts 223, with their overall height decreasing sequentially from front to back. When energized, electromagnets 231 generate magnetic force, thereby attracting magnetic components in rare earth waste. By adjusting the magnetic force generated by multiple electromagnets 231, decreasing sequentially from front to back, the magnetic components in the rare earth waste are sorted. The number of receiving hoppers 232 is the same as the number of electromagnets 231, capable of catching materials falling after the magnetism weakens. Impurities are transported by a separate conveyor belt 223 installed below the receiving hoppers 232, or impurities are collected by placing containers below the receiving hoppers 232 for subsequent processing, achieving the effect of sorting according to magnetic strength. The separation is achieved through the limiting frame 1. The position of the bottom opening of the hopper 11 is restricted, so that the falling position of the rare earth waste is between the baffles 225. The hopper 11 receives a certain amount of rare earth waste, and the drive motor 13 drives the unloading shaft 12 to rotate at a certain speed, so that the falling speed of the rare earth waste matches the speed of the conveyor belt 223, ensuring the thickness of the rare earth waste above the conveyor belt 223. When the conveyor belt 223 moves the rare earth waste to the outside of the front support pipe 239, the magnetic tile 238 inside the support pipe 239 can attract the components affected by magnetism. Thus, the components attracted by the magnetic tile 238 continue to move backward with the conveyor belt 223 to the bottom of the electromagnet 231, and are sorted by the electromagnet 231. In this way, the components affected by magnetic force will fall directly into the receiving hopper 232 below to prevent the components from accumulating and affecting the impurity removal efficiency.
