Description

Technical Field

[0001] The invention belongs to the technical field of recycling devices, and in particular relates to a NdFeB waste recycling device. Background Art

[0002] NdFeB, simply put, is a kind of magnet. Different from the magnets we usually see, it is called "King of Magnets" because of its excellent magnetic properties. NdFeB waste contains a large amount of rare earth elements neodymium, iron and boron, and its characteristics are hard and brittle. The method of recycling NdFeB waste mostly adopts atmospheric pressure leaching, through the chemical reaction between the acidic extractant and the waste, so as to complete the recovery of rare earth elements neodymium, iron and boron.

[0003] The existing NdFeB waste recovery device is provided with a stirring mechanism. The stirring mechanism cooperates with the filtering mechanism to stir and mix the NdFeB waste and the organic extractant, and at the same time filter the waste sediment and rare earth elements. The feeding mechanism cooperates with the material control mechanism to achieve the interval feeding of the waste sediment and the rare earth elements. The feeding mechanism cooperates with the vibration mechanism to quickly filter the waste sediment and the rare earth elements, so that the rare earth elements fall into the first material box for collection.

[0004] In the process of intermittent feeding and filtering of waste materials in the existing device, the extractant will enter the filtering mechanism. Although this can complete the filtering and recovery of the waste materials, when the next waste to be recycled needs to be recovered, the extractant in the filtering mechanism must be added back into the stirring mechanism to achieve the reuse of the extractant. This process is not only time-consuming and labor-intensive, but may also pose a threat to the personal safety of the staff.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a NdFeB waste recovery device to overcome the shortcomings in current practical applications. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0052] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0054] A connecting mechanism 500, one end of which is mounted on the outside of the extraction box 600, and the other end of which is connected to the lifting mechanism 400, and the other end of which is intermittently slidably matched with the strip groove 310 and the arc groove 320 provided on the arc frame 300, respectively, the strip groove 310 is vertically provided on the arc frame 300, the arc groove 320 is horizontally provided on the arc frame 300, the strip groove 310 is connected with the arc groove 320, and the arc groove 320 is located above the strip groove 310;

[0055] In the initial state, the connection mechanism 500 is slidably matched with one end of the strip groove 310 on the arc groove 320 away from the extraction tank 600, and the extraction box 600 is located on the side directly above the extraction tank 210. The filter frame 700 is rotated and rotated to the outside of the extraction box 600, so that the waste to be recycled can be placed on the filter plate 710, and the filter frame 700 is rotated and rotated to the bottom of the extraction box 600, and the filter frame 700 and the extraction box 600 are connected as a whole, thereby completing the device for loading the waste;

[0076] In a preferred embodiment, the length of the connecting rod B832 is half the length of the connecting rod A831.

[0077] The working principle of the present invention is:

[0078] In the initial state, the pulley 540 is slidably matched with one end of the strip groove 310 on the arc groove 320 away from the extraction tank 210, and the extraction box 600 is located on one side directly above the extraction tank 210. The filter frame 700 is rotated and rotated to the outside of the extraction box 600, so that the waste to be recycled can be placed on the filter plate 710, and the filter frame 700 is rotated and rotated to the bottom of the extraction box 600, and the filter frame 700 and the extraction box 600 are connected as a whole, thereby completing the device's waste loading work;

[0079] The motor A410 drives the transmission member A420 to rotate, and the transmission member A420 drives the screw 430 to rotate. The screw 430 can drive the connecting block 520 to rotate along the arc groove 320 by rotating and being threadedly connected with the screw sleeve 530. The connecting block 520 drives the extraction box 600 and the filter plate 710 to rotate synchronously toward the direction just above the extraction tank 210 through the annular sleeve 510. When the lifting mechanism 400 drives the pulley 540 to rotate to the extreme position of the arc groove 320 and slides with the strip groove 310, the extraction box 600 and the filter frame 700 are rotated to the top of the extraction tank 210. The lifting mechanism 400 drives the pulley 540 to rotate to the extreme position of the arc groove 320 and slides with the strip groove 310. The matching manner of the strip groove 310 and the arc groove 320 can drive the connection block 520 to move vertically along the opening track of the strip groove 310. The connection block 520 drives the extraction box 600 and the filter frame 700 to move toward the extraction tank 210 through the annular sleeve 510, so that the extraction box 600 and the filter frame 700 can be moved into the extraction box 600 and immersed in the extractant. The extractant enters the extraction box 600 through the filter plate 710 and the waste undergoes a chemical reaction to be decomposed into waste sediment and rare earth elements. The rare earth elements can enter the extraction tank 210 through the filter plate 710, and the waste sediment is retained on the filter plate 710.

[0080] The motor A410 is controlled to work in the reverse direction, so that the screw rod 430 drives the connecting block 520 to move vertically upward and slide with the arc groove 320 again, and the connecting block 520 can drive the extraction box 600 and the filter frame 700 to move upward and rotate, so that the extraction box 600 and the filter frame 700 can be rotated to the side directly above the extraction tank 210 again, which not only makes it convenient for the staff to collect the waste sediments retained on the filter plate 710, but also makes it convenient to place the next waste to be recycled;

[0081] The motor B811 drives the main shaft 813 to rotate through the transmission member B812, and the main shaft 813 drives the straight frame 814 and the stirring blade A860 thereon to revolve synchronously, and the straight frame 814 drives the rotation component 820, the linkage component 830, the rotating shaft 840 and the stirring blade B850 thereon to revolve;

[0082] The linkage gear 822 can drive the fixed wheel A823 coaxial therewith to rotate by means of revolution and meshing with the fixed gear 821. The fixed wheel A823 can drive the connecting belt 825 to rotate by means of cooperation with the fixed wheel B824. The connecting belt 825 drives the plurality of self-rotating wheels 826 to rotate. The self-rotating wheels 826 drive the rotating shaft 840 to rotate. The rotating shaft 840 drives the stirring blades B850 thereon to rotate. The stirring blades B850 can improve the stirring effect of the waste and the extractant by means of revolution and rotation.

[0083] Multiple sliders 816 rotate synchronously with the crossbar 814. A slider 816 connected to the spring 817 drives the spring 817 to be squeezed under the action of the rotating centrifugal force. A slider 816 connected to the spring 817 drives the rotating shaft 840 thereon to move. One rotating shaft 840 can drive the other rotating shafts 840 connected to the connecting rod A831 to move horizontally at equal intervals by moving and cooperating with multiple connecting rods A831 and connecting rods B832. Multiple rotating shafts 840 drive their respective stirring blades B850 to move horizontally at equal intervals, which can expand the stirring range of the waste material, so that the waste material accumulated on the filter plate 710 can quickly contact with the extractant, thereby accelerating the rate of chemical reaction between them.

[0084] The above is the working principle of the NdFeB waste recovery device.
