[0002] Particle size grading is a very important link in the field of natural graphite processing. Different particle sizes of natural graphite correspond to different application fields. For example, in the process of preparing battery negative materials, the spheroidized graphite is generally introduced into the next process by an air flow classifier, and the fine powder produced in the spheroidization process is collected to prevent adhesion to the surface of the spherical graphite and affect the final performance of the spherical graphite.

[0003] In the prior art, the classification of graphite is generally carried out by an air flow vortex classifier. The material moves with the airflow under the action of the fan suction, and under the action of the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles meeting the particle size requirement pass through the gap between the classification wheel blades into the cyclone separator or dust collector for collection, and the coarse particles lose speed after colliding with the wall, and then descend along the cylinder wall to the secondary air inlet, and the coarse and fine particles are separated by the strong washing action of the secondary air.

[0032] Further, the motor 2 drives the grading turbine 3 to rotate, forming a strong centrifugal force in the grading turbine 3.

[0035] A chute 46 (as shown in Figure 8 ) is formed in the upper end of the rotating cylinder 10 and communicates with the feed groove 8, the bottom of the feed groove 8 and the impurity removal groove 9 communicates with the lower end of the rotating cylinder 10, the bottom of the two feed grooves 8 is fixedly connected with a sealing box 20 through two discharge pipes 19, and the inner wall of the sealing box 20 communicates with the side wall of the feed pipe 4 away from the classifier shell 1.

[0036] As shown in Figure 1 , Figure 4 , Figure 8 , the ground graphite from the outside enters the two feed grooves 8 through the chute 46, at this time the magnetic plate 17 located in the feed groove 8 can adsorb the iron metal existing in the graphite, and the graphite entering the classifier shell 1 is preliminarily screened, avoiding the fact that some iron metal materials may exist in the graphite in the prior art, which can easily collide with the iron metal materials in the classification turbine 3, not only producing a large abnormal sound, but also easily causing damage to the classification turbine 3.

[0037] The upper end of the sealing box 20 is fixedly connected with two cams 21 through a fixed rod, the two cams 21 are fixedly connected between them, the two cams 21 are located in the fixed ring 13, a rotating rod 22 is rotatably connected to the side wall of the second plate 16 away from the magnetic plate 17, the side wall of the rotating rod 22 is in contact with the side wall of the cam 21, and the protruding parts of the two cams 21 correspond to the two feed grooves 8 one by one.

[0038] As shown in Figure 4As shown, the protrusions of the two cams 21 correspond to the two feed grooves 8 respectively, at this time, the two rotating rods 22 and the two second plates 16 can drive the two magnetic plates 17 to approach and adhere to the side wall of the partition plate 12 respectively, and the recesses on the two cams 21 correspond to the two impurity removal grooves 9 respectively, at this time, the two rotating rods 22 corresponding to the two impurity removal grooves 9 are located in the recesses between the two cams 21, and under the action of the plurality of first springs 18, the two magnetic plates 17 at the position are away from the two partition plates 12 respectively, and thus the iron metal on the partition plate 12 in the impurity removal groove 9 can be easily removed, keeping the partition plate 12 clean and facilitating subsequent use.

[0039] The impurity removal groove 9 is provided with a cleaning mechanism, which comprises two reciprocating lead screws 23 rotatably connected to the top of the two impurity removal grooves 9. The side wall of the reciprocating lead screw 23 is threadedly connected with a sliding block 24, and the sliding block 24 is fixedly connected with a plurality of bristles 25 close to the side wall of the partition plate 12. The side wall of the sliding block 24 is slidably connected with the inner wall of the impurity removal groove 9. The side wall of the two reciprocating lead screws 23 located above the fixed block 7 is fixedly connected with two first wheels 27 respectively, and the two first wheels 27 are connected with a synchronous belt.

[0040] Further, the side wall of the bristle 25 is in close contact with the side wall of the partition plate 12 located in the impurity removal groove 9. During the rotation of the reciprocating lead screw 23, the sliding block 24 drives the plurality of bristles 25 to move up and down, thereby increasing the cleaning intensity of the iron metal on the partition plate 12.

[0041] The fixed block 7 is provided with a rotating mechanism for driving the rotating cylinder 10 to rotate, which comprises a one-way bearing 30 (as shown in Figure 7 The upper end of the fixed block 7 is fixedly connected with a U-shaped plate 26, the side wall of the U-shaped plate 26 is rotatably connected with a vertical rod 31, the side wall of the vertical rod 31 is fixedly connected with the inner ring side wall of the one-way bearing 30, the outer ring side wall of the one-way bearing 30 is fixedly connected with the upper end of the rotating cylinder 10 through a plurality of supports, the upper end of the U-shaped plate 26 is fixedly connected with a first frame 33, the inner wall of the first frame 33 is sealingly and slidably connected with a third plate 34, the side wall of the third plate 34 is fixedly connected with a toothed plate 35, the upper end of the vertical rod 31 is fixedly connected with a gear 32, and the side wall of the toothed plate 35 is engaged with the side wall of the gear 32.

[0042] As shown in Figure 6 and Figure 7 When the toothed plate 35 slides to the right and is in close contact with the inner side wall of the first frame 33, the toothed plate 35 drives the gear 32 to rotate clockwise by half a turn at this time, the inner ring of the one-way bearing 30 drives the outer ring to rotate, thereby driving the rotating cylinder 10 to rotate by half a turn, replacing the position of the partition plate 12 located in the two feed grooves 8 and the two impurity removal grooves 9, thereby increasing the continuous adsorption effect of the iron metal, and when the toothed plate 35 slides to the left to drive the gear 32 to rotate counterclockwise, the inner ring of the one-way bearing 30 does not drive the inner ring to rotate at this time.

[0043] The fourth plate 39 is sealingly and slidably connected to the inner wall of the first frame 33, the side wall of the third plate 34 is elastically connected to the side wall of the fourth plate 39 through a plurality of second springs 40, the pressure sensor 42 is installed on the inner wall of the first frame 33, the side wall of the fourth plate 39 is provided with a gas injection port 41, the gas injection port 41 is provided with an electromagnetic valve, the pressure sensor 42 and the electromagnetic valve are electrically connected to an external power supply, and the inner wall of the first frame 33 between the third plate 34 and the fourth plate 39 is fixedly connected with two gas outlet pipes 43, the side walls of the two gas outlet pipes 43 away from the first frame 33 are fixedly connected with the lower ends of the two sliding blocks 24 respectively (as shown in Figure 6 ).

[0044] The opening and closing control process of the electromagnetic valve by the pressure sensor 42 is prior art and will not be repeated here.

[0045] The second frame 36 is fixedly connected to the upper end of the first frame 33, the fifth plate 44 is sealingly and slidably connected to the inner wall of the second frame 36, the one-way air suction pipe 37 is fixedly connected to the inner wall of the second frame 36, the one-way air suction pipe 37 only allows gas to enter the first frame 33 from the outside, the inner wall of the second frame 36 is in communication with the inner wall of the first frame 33 through the one-way air outlet pipe 38, the one-way air outlet pipe 38 only allows gas to enter the first frame 33 from the second frame 36, the second wheel 28 is fixedly connected to the side wall of the movable shaft of the motor 2, one of the upper ends of the reciprocating lead screws 23 penetrates through the side wall of the U-shaped plate 26 and is fixedly connected with the third wheel 29, the second wheel 28 and the third wheel 29 are connected with a synchronous belt, and the upper end of the third wheel 29 away from the center is rotatably connected with the side wall of the fifth plate 44 through the connecting rod 45.

[0046] Further, the motor 2 drives the third wheel 29 to rotate through the second wheel 28 and the synchronous belt during rotation, at this time, the third wheel 29 drives the fifth plate 44 to slide back and forth on the inner wall of the second frame 36 through the connecting rod 45, so that the space in the second frame 36 is intermittently increased or decreased, at this time, the second frame 36 can intermittently pump air into the first frame 33 through the one-way air suction pipe 37 and the one-way air outlet pipe 38, the space in the first frame 33 where the pressure sensor 42 is located will store air, so that the pressure in the space is increased, when the pressure in the space reaches the set upper limit of the pressure sensor 42, the electromagnetic valve is turned on at this time, so that the high-pressure gas in the space is instantaneously sprayed out through the gas injection port 41, driving the third plate 34 to move to the right (as shown in Figure 7 ), then the high-pressure gas will flow out through the gas outlet pipe 43, blowing the side wall of the baffle plate 12 in the impurity removal tank 9, and increasing the cleaning of the iron metal adsorbed at the baffle plate 12 again;

[0047] It should be noted that the diameter of the exhaust pipe 43 is much smaller than the diameter of the jet nozzle 41. As a result, the high-pressure gas that is instantly ejected from the jet nozzle 41 cannot flow out through the exhaust pipe 43, which will cause the third plate 34 to move to the right. After the high-pressure gas flows out through the exhaust pipe 43, the third plate 34 will move to the left to its original position under the action of multiple second springs 40, so as to facilitate the rotation of the rotating cylinder 10 next time.

[0048] When screening negative electrode graphite materials, the drive motor 2 rotates, which drives the classifying turbine 3 to rotate, forming a strong centrifugal force in the classifying turbine 3. Then, the ground graphite is added to the two feed troughs 8 through the two inclined grooves 46. At this time, the magnetic plate 17 located in the feed trough 8 can adsorb the iron metal present in the graphite, and perform preliminary screening of the graphite entering the classifier housing 1. This avoids the possibility that some iron metal materials may be present in the graphite in the prior art, which would easily cause the iron metal materials to collide randomly in the classifying turbine 3, not only producing a large abnormal noise, but also easily causing damage to the classifying turbine 3.

[0049] Subsequently, the graphite enters the classifier housing 1 through the feed pipe 4 via two discharge pipes 19 and a sealed box 20. Then, the graphite enters the classifier turbine 3, where a strong centrifugal force is generated. During the process of natural graphite material entering the classifier housing 1 through the feed pipe 4, the heavier material sinks to the inner wall of the classifier housing 1 due to gravity and flows out through the discharge pipe 6. The lighter material is further classified by the air force than gravity and is further classified by the classifier turbine 3. The classified fine powder is carried out of the classifier housing 1. The material is centrifuged into the classifier housing 1, thereby improving the classification processing capacity and the classification accuracy.

[0050] During the rotation of motor 2, the third wheel 29 is driven to rotate via the second wheel 28 and the synchronous belt. The third wheel 29, through the connecting rod 45, drives the fifth plate 44 to slide back and forth on the inner wall of the second frame 36, causing the space within the second frame 36 to intermittently increase or decrease. At this time, the second frame 36 can intermittently pump air into the first frame 33 through the one-way suction pipe 37 and the one-way exhaust pipe 38, causing air to accumulate in the space of the first frame 33 located within the pressure sensor 42, increasing the pressure within this space. When the pressure within this space reaches the upper limit set by the pressure sensor 42, the solenoid valve is energized and opened, causing the high-pressure gas in this space to be instantly ejected through the jet nozzle 41, driving the third plate 34 to move to the right. When the toothed plate 35 slides to the right and is in contact with the inner wall of the first frame 33, the toothed plate 35 will drive the gear 32 to rotate half a turn clockwise (e.g., ...). Figure 6 and Figure 7The outer ring of the one-way bearing 30 is driven to rotate by the inner ring, and the rotating cylinder 10 is driven to rotate half a circle, and the position of the partition plate 12 in the two feeding grooves 8 and the two impurity removal grooves 9 is replaced, that is, the partition plate 12 cleaned in the impurity removal groove 9 is rotated to the feeding groove 8, and the continuous adsorption effect on ferrous metal is increased;

[0051] Since the two cams 21 protrude correspondingly to the two feeding grooves 8, the two cams 21 can drive the two magnetic plates 17 to approach and adhere to the side wall of the partition plate 12 in the feeding groove 8 through the two rotating rods 22 and the two second plates 16, and the ferrous metal can be adsorbed on the side wall of the partition plate 12. The recesses on the two cams 21 correspond to the two impurity removal grooves 9, and the two rotating rods 22 corresponding to the two impurity removal grooves 9 are located in the recess between the two cams 21. Under the action of the plurality of first springs 18, the two magnetic plates 17 at the position are away from the two partition plates 12, respectively, and the ferrous metal on the partition plate 12 in the impurity removal groove 9 is removed, the cleanliness of the partition plate 12 is maintained, and the subsequent use is facilitated;

[0052] At the same time, the third wheel 29 drives one of the reciprocating lead screws 23 to rotate, and under the action of the two first wheels 27 and the synchronous belt, the two reciprocating lead screws 23 are driven to rotate synchronously, so that the sliding block 24 drives the plurality of bristles 25 to move up and down, and the cleaning force on the ferrous metal on the partition plate 12 is increased. The high-pressure gas sprayed through the air outlet 41 flows out through the air outlet pipe 43, and the partition plate 12 on the side wall of the impurity removal groove 9 is blown, and the ferrous metal adsorbed on the partition plate 12 is cleaned again.

[0053] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
