Description

Technical Field

[0001] The utility model relates to the technical field of magnet sintering, in particular to a magnet sintering device based on the recycling of Alnico alloy waste materials. Background Art

[0002] In modern industrial production, Alnico alloy, as an important magnetic material, is widely used in various electronic devices such as motors, sensors, and speakers. However, with the expansion of production scale and the continuous progress of technology, the generation amount of Alnico alloy waste materials is also increasing day by day. Traditionally, these waste materials are often regarded as useless things and are discarded or piled up at will, which not only wastes precious resources but also may cause environmental pollution.

[0003] Reference patent (Publication No.: CN115074535B; Publication Date: May 14, 2024) relates to a method for recovering cobalt and nickel from Alnico iron alloy waste materials, including: A) calcining the Alnico iron alloy waste materials at 400 - 600 °C to demagnetize them and then making them into powders; B) mixing the powders, water, and concentrated sulfuric acid for sulfuric acid leaching to obtain a leached post - solution; C) heating the leached post - solution to 70 - 90 °C, mixing it with sodium chlorate, adjusting the pH value to 4 - 5, and filtering to obtain a filter residue and an iron - removed post - solution; D) using P204 extractant, C272 extractant, and kerosene to extract and separate the iron - removed post - solution to obtain a nickel - cobalt sulfate solution and an aluminum - containing organic phase; E) using P507 extractant and kerosene to extract and separate the nickel - cobalt sulfate solution to obtain a nickel sulfate solution and a cobalt sulfate solution; F) respectively evaporating and crystallizing the nickel sulfate solution and the cobalt sulfate solution to obtain cobalt sulfate heptahydrate crystals and nickel sulfate hexahydrate crystals. The recovery method can obtain relatively high cobalt recovery rate and nickel recovery rate.

[0004] Traditional magnet sintering devices for the recycling of Alnico alloy waste materials often neglect the pretreatment of the shape and size of the waste materials. When the waste materials directly enter the sintering process, due to irregular shapes or oversized sizes, it is difficult to mix fully with the sintering materials, reducing the recycling rate of the waste materials. At the same time, it increases energy consumption and production costs. Secondly, it is difficult to ensure the uniform heating of the waste materials during the sintering process, affecting the quality and performance consistency of the sintered magnets. Therefore, the utility model provides a magnet sintering device based on the recycling of Alnico alloy waste materials. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a magnet sintering device based on the recycling of Alnico alloy waste materials, which solves the problems that the pretreatment of the shape and size of the waste materials is neglected, resulting in the difficulty of fully mixing with the sintering materials due to irregular shapes or oversized sizes when the waste materials directly enter the sintering process, reducing the recycling rate of the waste materials, increasing energy consumption and production costs at the same time, and secondly, it is difficult to ensure the uniform heating of the waste materials during the sintering process, affecting the quality and performance consistency of the sintered magnets.

[0006] To achieve the above object, the present utility model is realized through the following technical solutions: A magnet sintering device based on the recycling of alnico alloy waste, including a sintering main body, and a magnet sintering mechanism for the recycling of alnico alloy waste is provided on the sintering main body.

[0014] Beneficial effects

[0015] The present utility model provides a magnet sintering device based on the recycling of alnico alloy waste. Compared with the prior art, the following beneficial effects are achieved:

[0016] First, the present utility model feeds the alnico alloy waste into the interior of the sintering main body through the feeding bracket, and then the first crushing shaft and the second crushing shaft operate to crush it and then perform the sintering operation. The alnico alloy waste is refined, making it easier to process and utilize subsequently, reducing waste caused by irregular waste shapes or oversized sizes. The crushed waste can be more fully mixed with the sintering material, improving the overall recovery rate of the waste. Moreover, the crushed waste particles are smaller and more uniform, helping to form a denser and more uniform organizational structure during the sintering process, thereby improving the quality and performance of the sintered magnet. Then, the flap rotates under the action of the drive shaft through the transmission bracket to turn and sinter the crushed alnico alloy waste, ensuring uniform heating of the alnico alloy waste during the sintering process. As the particles turn, the high-temperature gas and sintering aids can more fully contact the waste particles, promoting the sintering reaction.

[0017] Second, after the sintering of the present utility model is completed, the discharge plate is pulled out for discharging, and then it is sent into the interior of the filter frame to effectively remove the tiny impurities, unreacted raw material particles, and possible pollutants in the sintered magnet. Then, the incompletely reacted raw materials are sintered again to improve the working efficiency of the equipment. Then, the cam rotates through the motor to push the filter frame. The filter frame slides inside the slide rail bracket through the slider, and the right end of the slider contacts the support block. The support block is compressed by the spring. The combined design of the support block and the spring plays a buffering role, reducing the impact and vibration generated when the cam rotates, and enabling the filter frame to perform reciprocating shaking work, which helps prevent the filter mesh holes from being blocked by large pieces of materials or viscous substances and keeps the filter channel unobstructed.

The filter frame 602 slides inside the slide rail bracket 6 through the slider 601, and the right end of the slider 601 contacts the support block 604. The support block 604 is compressed by the spring 603. The combined design of the support block 604 and the spring 603 plays a buffering role, reducing the impact and vibration generated when the cam 704 rotates, and enabling the filter frame 602 to perform reciprocating shaking work, which helps prevent the filter mesh holes from being blocked by large pieces of materials or viscous substances and keeps the filter channel unobstructed. When the waste filtering is completed, by controlling the hydraulic rod 702 and the motor 703, the cam 704 is lowered to separate the cam 704 from the filter frame 602, which facilitates the movement and disassembly of the filter frame 602 for cleaning and maintenance.
