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 scope of protection of the present utility model.

[0022] Please see Figures 1-4 As shown, a rare earth filtration and cleaning device includes a main box 1; a feeding hopper 2 with a wider top and narrower bottom is provided on the top of the main box 1, a vibration assembly 3 is provided inside the main box 1, and a screening assembly 4 is provided on the bottom edge of the side of the main box 1; the vibration assembly 3 includes a cleaning box 31 inside the main box 1, A springs 32 are provided on both sides of the cleaning box 31, one end of the A springs 32 is fixedly connected to the inner side wall of the main box 1, and an A vibration motor 33 is provided on the side of the cleaning box 31. The cleaning box 31 is inclined and its high end is located directly below the feeding hopper 2. A discharge trough 34 is opened at the low end of the cleaning box 31, and a guide plate 35 is provided on the surface of the discharge trough 34. The inner bottom surface of the cleaning box 31 is provided with A screen 36 is placed; the screening assembly 4 includes a secondary box 41 on the bottom edge of the side of the main box 1, a screening box 42 is set inside the secondary box 41, springs 43 are set on both sides of the screening box 42, a vibration motor 44 is set on the other side of the screening box 42, a filter screen plate 45 is set on the bottom surface of the screening box 42, the screening box 42 is set at an inclination and a discharge trough 46 is opened at the lower end, and a discharge plate 47 is set on the surface of the discharge trough 46; a water tank 9 is set on the front of the main box 1, a water pump 10 is set inside the water tank 9, a connecting pipe 11 is set at the water outlet of the water pump 10, one end of the connecting pipe 11 is connected to an L-shaped pipe 12, and a cleaning nozzle 13 is set at the bottom of the L-shaped pipe 12.

[0023] During operation, after the A vibration motor 33 starts, it drives the cleaning box 31 to vibrate at high frequency along the direction of the A spring 32. The rare earth falling from the feeding hopper 2 rolls in the cleaning box 31 with the vibration. The water pump 10 draws the cleaning liquid from the water tank 9 and sprays it evenly through the cleaning nozzle 13 of the L-shaped pipe 12. The sewage flows into the bottom of the main box 1 through the strainer 36. The cleaned rare earth slides along the inclined cleaning box 31 to the discharge chute 34 and is guided by the guide plate 35 to the screening component 4. The vibration cleaning combined with the spray rinsing realizes the physical separation of rare earth and impurities, solves the problem of impurity residue caused by traditional stirring and mixing, and improves the cleaning efficiency.

[0024] Furthermore, a material drop chute 5 is provided on the side of the main box 1. The material drop chute 5 is connected to the discharge chute 34 through the guide plate 35. A rectangular groove 6 is provided on the top of the auxiliary box 41. The rectangular groove 6 is located at the bottom of the material drop chute 5. A bottom material groove 7 is provided on the surface of the auxiliary box 41. The bottom material groove 7 is connected to the discharge chute 46 through the discharge plate 47. A storage box 8 is provided on the surface of the auxiliary box 41 at the bottom of the bottom material groove 7.

[0025] During operation, the cleaned rare earths fall through the guide plate 35 into the rectangular groove 6 at the top of the auxiliary box 41 via the discharge chute 5. After entering the screening box 42, they are driven to vibrate by the B vibration motor 44. Qualified rare earths slide along the inclined screening box 42 to the discharge chute 46 and are guided into the bottom material chute 7 via the discharge plate 47, and finally fall into the storage box 8. The material guiding path is seamlessly connected with the screening process, avoiding manual material transfer, reducing rare earth loss and shortening the processing cycle.

[0026] Furthermore, the tilt angle of the screening box 42 is the same as that of the washing box 31, and the lower end faces the side of the auxiliary box 41. The outlet end of the discharge chute 46 extends to the top of the bottom material chute 7.

[0027] During operation, both the washing box 31 and the screening box 42 are installed at an inclined angle, with the lower end of the screening box 42 facing the side of the auxiliary box 41, and the outlet of the discharge chute 46 vertically aligned with the bottom material chute 7, ensuring that qualified rare earths slide into the storage box 8 in a directional manner. The inclined angle matching design accelerates the flow of materials, prevents material accumulation and blockage in the screening box 42, and improves the continuity of screening.

[0028] Furthermore, the axes of spring A 32 and spring B 43 are both perpendicular to the inner wall of the main box 1, and the output shafts of vibration motor A 33 and vibration motor B 44 are both welded and fixed to the sides of the washing box 31 and the screening box 42.

[0029] During operation, spring A 32 and spring B 43 are vertically welded to the inner wall of the main box 1. The output shaft of vibration motor A 33 is rigidly connected to the side of the cleaning box 31, and the output shaft of vibration motor B 44 is bolted to the side of the screening box 42. The two motors synchronously generate horizontal reciprocating vibration. The vertical spring and the horizontal vibration work together to enhance the transmission of vibration force, prevent the cleaning box 31 and the screening box 42 from shifting, and ensure vibration stability.

[0030] Furthermore, the aperture of the filter screen 45 decreases gradually from the top to the bottom of the screening box 42, and the edge of the filter screen 45 is detachably connected to the inner bottom surface of the screening box 42 by bolts.

[0031] During operation, the filter screen plate 45 has a hole diameter of 2mm at the top, 1mm in the middle, and 0.5mm at the bottom. It is fixed to the bottom surface of the screening box 42 with bolts. Operators can disassemble and replace filter screen plates 45 with different hole diameter combinations. The multi-level hole diameter is suitable for rare earth grading and screening of different particle sizes. The bolt fixing simplifies the filter replacement process and improves the adaptability of the equipment.

[0032] Furthermore, a pull-out groove is provided on the side of the auxiliary box 41, and a collection box 48 is slidably connected inside the pull-out groove. The opening direction of the collection box 48 is aligned with the inclined lower end of the filter screen plate 45, and an anti-slip rubber pad is provided at the bottom of the collection box 48.

[0033] During operation, the collection box 48 is horizontally inserted into the auxiliary box 41 through the pull-out slot, with the opening facing the lower end of the filter screen plate 45. Unqualified rare earth particles slide into the collection box 48 along the filter screen plate 45. The bottom anti-slip rubber pad prevents the box from shifting. The pull-out collection box 48 quickly cleans up waste, and the anti-slip design prevents the box from slipping during operation, thus improving maintenance efficiency.

[0034] Working principle: Rare earth particles fall into the inclined cleaning box 31 inside the main box 1 through the feeding hopper 2. The A vibration motor 33 drives the cleaning box 31 to vibrate at high frequency along the A spring 32. At the same time, the water pump 10 draws the cleaning liquid from the water tank 9 and sprays it through the cleaning nozzle 13 of the L-shaped pipe 12 to wash the rare earth particles. The wastewater is discharged into the bottom of the main box 1 through the strainer 36. The cleaned rare earth particles slide along the inclined cleaning box 31 to the discharge chute 34 and fall into the screening box 42 of the auxiliary box 41 through the guide plate 35 and the drop chute 5. The B vibration motor 44 drives the screening box 42 to vibrate along the B spring 43. Qualified rare earth particles are intercepted by the filter screen 45 with progressively decreasing aperture and slide into the storage box 8 along the discharge chute 46 and the discharge plate 47. Unqualified particles are screened by the filter screen 45 and fall into the pull-out collection box 48, realizing integrated control of vibration cleaning, grading screening and waste collection.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
