It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0031] A rare earth material filtering device, such as Figure 1-Figure 8 As shown, it includes a base 1, a side frame 2, a top frame 3, a filtering mechanism, a driving mechanism and a cleaning mechanism. The top of the base 1 is connected to the side frame 2, and the top of the side frame 2 is connected to the top frame 3. The side frame 2 is provided with a filtering mechanism for filtering rare earth materials. A drain pipe is provided at the bottom of the side frame 2, and a drain valve is provided at the drain pipe.

The filtering mechanism includes a filter cartridge 44, and the side frame 2 is provided with a driving mechanism for driving the filtering mechanism to operate. The top frame 3 is provided with a cleaning mechanism for unblocking the filter cartridge 44.

[0032] like Figure 2 and Figure 3 As shown, the filtering mechanism includes a driving wheel 43, a friction ring 441, a feed hopper 45 and a discharge hopper 46. Two driving wheels 43 are installed on the left and right sides of the top of the side frame 2, and the two driving wheels 43 are arranged front and back. The left and right sides of the filter cartridge 44 are connected with friction rings 441. The filter cartridge 44 is placed in the side frame 2, and the friction rings 441 on both sides of the filter cartridge 44 are in contact with the driving wheel 43, so that the driving wheel 43 supports the filter cartridge 44 through the friction ring 441. The upper left part of the side frame 2 is connected to the feed hopper 45, and the lower right part of the side frame 2 is connected to the discharge hopper 46. The end of the feed hopper 45 extends into the filter cartridge 44, and the end of the filter cartridge 44 is aligned with the discharge hopper 46.

[0033] like Figure 2As shown, the driving mechanism includes a servo motor 41 and a belt transmission group 42. The servo motor 41 is installed on the left side of the side frame 2, and the belt transmission group 42 is connected between the output shaft of the servo motor 41 and the driving wheel 43 on the left front side, so that the operation of the servo motor 41 can drive the driving wheel 43 on the left front side to rotate.

[0034] like Figure 6-Figure 8 As shown, the cleaning mechanism includes a sliding frame 71, an elastic member 72, an insertion rod 73, an extrusion ring 74 and a pressure column 75. The sliding frame 71 is slidably connected to the middle of the top of the top frame 3, and an elastic member 72 is connected between the sliding frame 71 and the top frame 3. The elastic member 72 is a return spring. A plurality of insertion rods 73 are evenly spaced and connected to the bottom of the sliding frame 71. The size of the insertion rod 73 is smaller than the mesh size of the filter cartridge 44 so that the insertion rod 73 can be inserted into the mesh of the filter cartridge 44. The insertion rod 73 is elastic and can be bent. A pressure column 75 is connected to the middle of the bottom of the sliding frame 71. A squeezing ring 74 is connected to the middle of the filter cartridge 44. The squeezing ring 74 is used to squeeze the pressure column 75 upward.

[0035] like Figure 3-Figure 5 As shown, it also includes a feeding mechanism, which includes a lifting frame 61, an inner gear ring 62, a transmission gear 63, a spiral feeding barrel 64, an outer gear ring 65 and a protective shell 651. The inner gear ring 62 is connected to the inside of the left friction ring 441, and the lifting frame 61 is connected to the left side of the side frame 2. The upper part of the lifting frame 61 is rotatably connected to the transmission gear 63, and the transmission gear 63 is engaged with the inner gear ring 62. The middle part of the right side of the lifting frame 61 is rotatably connected to the spiral feeding barrel 64, and the spiral feeding barrel 64 is located in the filter cartridge 44 and fits with the filter cartridge 44. The outer gear ring 65 is connected to the left side of the spiral feeding barrel 64, and the outer gear ring 65 is engaged with the transmission gear 63. A protective shell 651 is connected to the lifting frame 61, and the protective shell 651 covers the outer gear ring 65 for protecting the outer gear ring 65 to prevent rare earth from splashing on the outer gear ring 65 during feeding.

[0036] When it is necessary to filter the rare earth material, the filtering device can be used. When in use, the rare earth material after adding water is first added into the filter cartridge 44 through the feed hopper 45, and then the servo motor 41 can be controlled to operate to drive the driving wheel 43 to rotate through the belt transmission group 42. When the driving wheel 43 rotates, it drives the friction ring 441 and the filter cartridge 44 to rotate, so that the rare earth material can be screened and filtered, and the rare earth material and water can fall into the side frame 2 through the filter cartridge 44, while impurities will remain in the filter cartridge 44. When the friction ring 441 rotates, it can drive the inner gear ring 62 to rotate. When the inner gear ring 62 rotates, it can drive the outer gear ring 65 to rotate through the transmission gear 63. The rotation of the outer gear ring 65 drives the spiral feeding barrel 64 to rotate, thereby conveying the material in the barrel. After conveying, The impurities can be discharged through the discharge hopper 46. During screening, some impurities will be blocked in the mesh of the sieve hole. When the filter cartridge 44 rotates, it can drive the extrusion ring 74 to rotate. When the extrusion ring 74 rotates, it will continuously squeeze the pressure column 75 and the sliding frame 71 to move upward, and the elastic member 72 is compressed. When the extrusion ring 74 rotates until it no longer contacts the pressure column 75, the pressure column 75 and the sliding frame 71 move downward under the action of the elastic member 72, thereby repeatedly driving the sliding frame 71 to move up and down. When the sliding frame 71 moves up and down, it drives the insertion rod 73 to move up and down. The insertion rod 73 moves downward and can be inserted into the mesh of the filter cartridge 44, thereby clearing the blocked mesh to prevent the mesh from being blocked and affecting the falling of the rare earth material, causing the rare earth material to be discharged along with the impurities.

[0037] like Figure 2 As shown, a rubber sleeve 51 is also included. The friction rings 441 on both sides are connected with rubber sleeves 51, which can increase the resistance between the driving wheel 43 and the friction ring 411 to prevent the driving friction ring 411 from slipping when rotating.

[0038] like Fig. 9 and Fig.10 As shown, it also includes a sorting mechanism, which includes a filter screen 81, a collecting bucket 82, a reciprocating screw 83, a scraper plate 84, a discharge pipe 85 and a transmission assembly. The filter screen 81 is connected to the upper inner part of the side frame 2, and the collecting buckets 82 are connected to the left and right sides of the side frame 2. The two collecting buckets 82 are respectively located on the left and right sides of the filter screen 81. The reciprocating screw 83 is rotatably connected to the middle of the upper part of the side frame 2, and the reciprocating screw 83 is threadedly connected to the scraper plate 84, and the scraper plate 84 is slidably connected to the side frame 2. The bottom of the scraper plate 84 contacts the top of the filter screen 81, and the lower parts of the two collecting buckets 82 are provided with discharge pipes 85, and valves are provided at the discharge pipes 85. A transmission assembly is provided between the friction ring 441 and the reciprocating screw 83, and the transmission assembly is used to drive the reciprocating screw 83 to rotate.

[0039] like Fig. 9 and Fig.10As shown, the transmission assembly includes a gear ring 861 and a driving gear 862 . The two friction rings 441 are connected to the gear ring 861 . Both sides of the reciprocating screw rod 83 are connected to the driving gear 862 . The gear ring 861 is meshed with the driving gear 862 .

[0040] When water and rare earth materials fall, they will fall on the filter screen 81, and the rare earth materials will be blocked by the filter screen 81, while water can pass through the filter screen 81 and fall into the side frame 2. When the friction ring 441 rotates, it can drive the gear ring 861 to rotate. The rotation of the gear ring 861 drives the reciprocating screw 83 to rotate through the driving gear 862. When the reciprocating screw 83 rotates, it can drive the scraper plate 84 to move back and forth left and right, thereby scraping the rare earth materials remaining on the filter screen 81 to the collecting buckets 82 on both sides, and collecting the rare earth materials through the collecting buckets 82. In this way, the water and rare earth materials can be collected separately.

[0041] like Fig.11 As shown, a water adding mechanism is also included, and the water adding mechanism includes a water delivery pipe 91, a water pump 92 and a spraying pipe 93. The spraying pipe 93 is installed on the side frame 2, and a water pump 92 is installed in the lower part of the side frame 2. The water delivery pipe 91 is connected between the water outlet end of the water pump 92 and the spraying pipe 93.

[0042] When the device is used to filter rare earth materials, water will flow to the bottom of the side frame 2. When in use, as the rare earth materials are transported, water will fall into the side frame 2. The water pump 92 can then be controlled to extract the water in the side frame 2 and transport it to the spray pipe 93 through the water delivery pipe 91, and then spray it out through the spray pipe 93 to clean the filter cartridge 44.
