Description

Technical Field

[0001] This utility model relates to the field of rare earth multi-element alloy technology, specifically a rare earth multi-element alloy particle screening device. Background Technology

[0002] Rare earth multi-element alloys are functional alloys made by fusing various rare earth elements with other metallic elements in a specific ratio. Due to their excellent magnetic, electrical, and thermal properties, they are widely used in high-tech fields such as new energy, aerospace, and electronic information. In the production and application of rare earth multi-element alloys, they often need to be processed into fragments of a specific particle size to meet the requirements of subsequent smelting, forming and other processes. Therefore, the precise screening of rare earth multi-element alloy fragments is a key link to ensure product quality and production efficiency.

[0003] Traditional rare earth multi-element alloy particle screening technologies mostly employ manual screening or simple mechanical vibration screening. Manual screening is not only labor-intensive and inefficient, but its accuracy is also greatly affected by human factors, making it difficult to guarantee the consistency of particle size. Simple mechanical vibration screening equipment generally suffers from unreasonable structural design and uncontrollable vibration parameters, leading to problems such as particle clogging of the screen and incomplete sorting during the screening process. This seriously affects the normal operation of subsequent processes, and also causes waste of raw materials and increased production costs. Therefore, we propose a rare earth multi-element alloy particle screening device. Utility Model Content

The front and rear ends of the top of the crushing and screening base 16 are provided with first fixing plates 19. A screen fixing frame 8 is slidably installed between the two first fixing plates 19. The screen fixing frame 8 cooperates with the screening rotation mechanism to repeatedly drive the sliding of the screen fixing frame 8.

[0025] Furthermore, a bidirectional guide plate 15 is provided on the top inner side of the crushing and screening base 16. The bidirectional guide plate 15 is located between the two first fixed plates 19 and is positioned below the screen fixing frame 8. Collection boxes 17 are provided at both ends of the crushing and screening base 16, corresponding to the bidirectional guide plate 15, forming the collection path for qualified particles after screening. The bidirectional guide plate 15, located below the screen fixing frame 8, can receive qualified particles that have passed through the screen 9, while the collection box 17, corresponding to the bidirectional guide plate 15, can collect the guided particles, achieving orderly collection of qualified particles, preventing particle scattering, and improving collection efficiency.

[0026] Furthermore, the crushing and screening base 16 has vertically distributed support blocks on its inner top. A bidirectional guide plate 15 is fixed to the top of the support block. The two ends of the bidirectional guide plate 15 are inclined downwards to ensure the stable installation and flow guiding function of the bidirectional guide plate 15. The vertical support block fixes the bidirectional guide plate 15 to make its position stable. The downward inclined distribution design at both ends guides the particles to flow to both ends, ensuring that qualified particles can flow smoothly to the collection box 17 and improving the reliability of flow guiding.

[0027] Furthermore, the screen fixing frame 8 is provided with guide strips 10 at the front and rear ends, and guide grooves are provided on both sides of the top of the first fixing plate 19.

The guide strips 10 on the back of the screen fixing frame 8 extend into the interior of the second fixing plate 20 to provide guidance and limit for the sliding of the screen fixing frame 8. The extended design of the second fixing plate 20 and the guide strips 10 on the back of the crushing and screening base 16 further enhances the stability of the screen fixing frame 8 when sliding, ensuring that the screen fixing frame 8 does not deviate during the reciprocating sliding process, and ensuring that the screening work is carried out stably.

[0029] Furthermore, a rectangular feeding trough 18 is provided on the inner side of the second support plate 7. The bottom of the inner side of the feeding trough 18 is inclined, and the bottom of the feeding trough 18 is located above the screening screen 9. It receives the particles discharged from the crushing cylinder 1 and guides them to the screening screen 9. The inclined design of the bottom of the inner side of the feeding trough 18 is to guide the particles to slide by gravity. The effect is to ensure that the particles can be smoothly transferred from the crushing stage to the screening stage, avoid particle accumulation, and ensure smooth material transmission.

[0030] Furthermore, the crushing cylinder 1 is fixed inside the first support plate 6. The bottom of the crushing cylinder 1 has multiple annularly distributed discharge ports, which are located above the feeding trough 18 to ensure the installation stability of the crushing cylinder 1. The multiple annularly distributed discharge ports at the bottom of the crushing cylinder 1 are located above the feeding trough 18, so that the crushed particles can fall accurately into the feeding trough 18, and the crushed particles can be accurately transported.

[0039] Screen fixing frame 8: Located between the second support plate 7 and the base, with the screen 9 snapped into the inner side, and guide strips 10 at the front and rear to drive the screen to slide and screen.

[0040] Screening mesh 9: It is snapped into the inner side of the screen fixing frame 8 and slides back and forth with the frame to screen particles through the mesh and separate qualified and unqualified fragments;

[0041] Guide bar 10: Located at the front and rear ends of the screen fixing frame 8, it cooperates with the guide groove of the first fixing plate 19 to ensure that the fixing frame does not deviate when it slides;

[0042] Transmission link 11: One end is connected to the reciprocating transmission shaft 12, and the other end is hinged to the hinge lug of the screen fixing frame 8, which converts the rotational motion into reciprocating sliding.

[0052] Working principle: After the device is started, the rare earth multi-element alloy raw material to be processed enters from the feed hoppers 2 on both sides of the top of the crushing cylinder 1. The first motor 3 drives the crushing shaft 4 to rotate at high speed. The crushing spiral blades 5 on the shaft shear and squeeze the raw material, breaking it into fine particles. The crushed particles are discharged through the annularly distributed discharge ports at the bottom of the crushing cylinder 1 and fall into the feeding trough 18 on the inner side of the second support plate 7 directly below. Since the bottom of the feeding trough 18 is inclined, the particles will slide out along the inclined surface and finally fall onto the screening screen 9 on the inner side of the screen fixing frame 8. The screening process is driven by the screening rotation mechanism. The second motor 14 is installed at the bottom of the second fixing plate 20 on the back of the crushing and screening base 16. Its output shaft drives the reciprocating transmission shaft 12 at the front end to rotate through the synchronous belt 13. The transmission connecting rod 11 connected to one end of the reciprocating transmission shaft 12 will then make an eccentric movement. The other end of the connecting rod is hinged to the hinge on the guide strip 10 on the back of the screen fixing frame 8, thereby pulling the screen fixing frame 8 to slide back and forth along the guide groove at the top of the first fixing plate 19. During operation, the screening screen 9 moves synchronously with the fixed frame, vibrating and screening the particles falling on the screen surface. Particles that meet the particle size requirements pass through the screen mesh, while those that do not meet the requirements remain on the screen surface. The screened particles are collected through different paths. Qualified particles that pass through the screening screen 9 fall into the bidirectional guide plate 15 below. The guide plate 15 is fixed by the vertical support block on the inner side of the top of the crushing and screening base 16, and its two ends are inclined downwards. The particles will flow along the inclined direction to the collection boxes 17 at both ends of the base. Qualified particles left on the screening screen 9 can be manually cleaned after the device is stopped. The entire device forms a stable spatial structure through multiple support plates and support columns. The crushing cylinder 1 is fixed inside the first support plate 6 by four support columns. The first support plate 6 is connected to the second support plate 7 through support column 1. The screen fixing frame 8 is limited between the second support plate 7 and the first fixing plate 19 between the crushing and screening base 16, ensuring that the material transmission path of each link is accurate and error-free, realizing automated processing from raw material crushing to grading and screening.
