[0014] Furthermore, the purification device for ultrafine silicon carbide micro powder comprises the following steps:

[0015] S1: After the silicon carbide particles are poured into the separation box, they will flow into the impurity removal box through the feed inlet. Start the drive motor, which will drive the rotating rod near the drive motor to rotate. The rotating rod will drive the circular plate to rotate, which will drive the connecting rod to rotate. The connecting rod will drive the impurity removal box to rotate in a plane. During the rotation of the impurity removal box, the two T-shaped sliders will move up and down in the two T-shaped separation grooves. The impurity removal box will also drive the two fixed blocks to slide left and right in the two T-shaped sliders, thus ensuring that the impurity removal box rotates vertically in a plane. During the plane rotation of the impurity removal box, the silicon carbide particles that have fallen on the bottom inner wall of the impurity removal box will be continuously turned up, thus preventing impurities from clogging the impurity removal holes at the bottom of the impurity removal box. The movement of the impurity removal box will cause the silicon carbide particles to turn up slightly.

[0016] S2: Silicon carbide particles filtered through the impurity removal holes fall onto the arc-shaped screening plate near the impurity removal chamber. During the movement of the impurity removal chamber, the rotating rod on the right side of the separation chamber rotates. Under the action of the pulley and synchronous belt, the rotating rod drives the rotating shaft to rotate. The rotating shaft drives the rod-driven disc to rotate. When the two rods on the rod-driven disc rotate, they touch two conical rods. After the rods on the rod-driven disc contact the conical rods, the conical rods move into the separation chamber. The two conical rods push the two arc-shaped screening plates to move simultaneously away from the rotating shaft. At this time, the arc-shaped screening plates drive... When two vibrating slide bars move in the same direction, the vibrating springs away from the rotating axis will undergo compression deformation. After the rod on the rod-driven disc leaves the conical rod, the vibrating springs will cause the two arc-shaped screening plates to rebound and vibrate under the action of elastic force. During the vibration process, the silicon carbide particles on the arc-shaped screening plates near the impurity removal box will sway left and right. During the swaying process, the silicon carbide particles will be dispersed, allowing the fine silicon carbide particles to separate and fall more smoothly from several screening holes. As the rod-driven disc continues to rotate, the two arc-shaped screening plates will repeatedly vibrate.

[0017] S3: When the purification of silicon carbide particles is finished, the driving motor is reversed, so that the driving motor drives the rotating rod to reverse, the rotating rod drives the gear to rotate, the gear drives the Z-shaped plate to rise under the action of a plurality of teeth, the Z-shaped plate drives the ladder-shaped round rod to rise, the ladder-shaped round rod drives the L-shaped round rod to rise, the L-shaped round rod drives the conical strip rod block in the discharging pipe to rise, the conical strip rod block drives the limiting hollow block to rise, so that the conical strip rod block leaves the discharging pipe, and at this time the limiting hollow block is still in the discharging pipe, since the impurity removal cylinder will continue to do plane rotation, the limiting hollow block is always in the discharging pipe in the movement process of the impurity removal cylinder, so that the conical strip rod block cannot accurately enter the discharging pipe in the process of descending, the L-shaped round rod slides left and right in the ladder-shaped round rod during the movement of the impurity removal cylinder, and simultaneously plays a limiting role, so that the L-shaped round rod and the ladder-shaped round rod cannot be separated, after the conical strip rod block leaves the discharging pipe, under the action of the conical inclined surface of the impurity removal cylinder, the impurities in the impurity removal cylinder will enter the discharging pipe in the shaking of the impurity removal cylinder, and the impurities are discharged into the collecting box through the discharging pipe;

[0018] S4: The driving motor is in an open state, and the rotating rod will continue to rotate, when the Z-shaped plate rises or falls, the gear will always be in contact with the first tooth or the last tooth, at this time, the adaptive spring on the top inner wall or the bottom inner wall of the Z-shaped plate will be compressed and deformed due to the movement of the Z-shaped plate, and the adaptive spring will always push the Z-shaped plate under the action of the elastic force, so that the first tooth or the last tooth is prevented from leaving the gear, thereby ensuring that the continuous movement of the impurity removal cylinder is not affected when the Z-shaped plate stops moving.

[0019] The present application has the following advantages:

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-8 As shown, this invention is a purification device for ultra-fine silicon carbide micro powder, including a separation box 1. A purification mechanism 100 is provided on the separation box 1. The purification mechanism 100 includes T-shaped separation grooves 101 formed on the inner walls of the front and back sides of the separation box 1. T-shaped sliders 102 are slidably installed in the two T-shaped separation grooves 101, and fixing blocks 103 are slidably installed on the two T-shaped sliders 102. The ends of the two fixing blocks 103 that are close to each other extend outside the two T-shaped sliders 102. A purification circular box 104 is fixedly installed on the two fixing blocks 103. The bottom inner wall of the purification circular box 104 is a conical inclined surface. The device also includes:

[0038] A plurality of impurity removal holes 105 are formed in the inner wall of the bottom of the impurity removal cylinder 104, a driving motor 106 is fixedly installed on the left side of the separation box 1, and two rotating rods 107 are rotatably installed on the left side and the right side of the separation box 1 respectively, the ends of the two rotating rods 107 close to each other extend into the separation box 1, the output shaft of the driving motor 106 is fixedly connected with the corresponding rotating rod 107, a circular plate 108 is fixedly installed on the end of each of the two rotating rods 107 close to each other, a connecting rod 109 is fixedly installed on the side of each of the two circular plates 108 close to each other, and the ends of the two connecting rods 109 close to each other are rotatably connected with the impurity removal cylinder 104. A feeding port 110 is fixedly installed on the top of the separation box 1.

[0039] As shown in Figure 1 , Figure 2 and Figure 3 , the front of the separation box 1 is provided with a discharging mechanism 2, the discharging mechanism 2 comprises a discharging groove 201 formed in the front of the separation box 1, a discharging pipe 202 is fixedly installed on the bottom of the impurity removal cylinder 104, the end of the discharging pipe 202 penetrates through the discharging groove 201 and is matched with the discharging groove 201, a conical bar block 203 is slidably installed in the discharging pipe 202, the top end of the conical bar block 203 extends into the impurity removal cylinder 104, a limiting hollow block 204 is fixedly installed on the bottom of the conical bar block 203, the limiting hollow block 204 is slidably connected with the discharging pipe 202, and a collection box 205 is fixedly installed on the front of the separation box 1.

[0040] The conical bar block 203 drives the limiting hollow block 204 to rise, so that the conical bar block 203 moves away from the discharging pipe 202, and at this time, the limiting hollow block 204 is still in the discharging pipe 202. Since the impurity removal cylinder 104 continuously rotates in the plane, the limiting hollow block 204 is always in the discharging pipe 202 during the movement of the impurity removal cylinder 104, so that the conical bar block 203 cannot accurately enter the discharging pipe 202 during the descending process.

[0041] As shown in Figure 2 and Figure 3 , the top end of the conical bar block 203 is provided with an adapting mechanism 3, the adapting mechanism 3 comprises an L-shaped circular rod 301 fixedly installed on the top end of the conical bar block 203, and a ladder-shaped circular rod 302 is slidably installed on the separation box 1, the bottom end of the ladder-shaped circular rod 302 extends into the impurity removal cylinder 104, and the right end of the L-shaped circular rod 301 extends into the ladder-shaped circular rod 302 and is slidably connected with the ladder-shaped circular rod 302.

[0042] The L-shaped round rod 301 can slide in the ladder-shaped round rod 302 when the impurity removal box 104 moves, and simultaneously functions as a limiting part, so that the L-shaped round rod 301 and the ladder-shaped round rod 302 cannot be separated. After the conical rod block 203 leaves the feeding pipe 202, the impurities in the impurity removal box 104 can enter the feeding pipe 202 under the action of the conical slope of the impurity removal box 104, and then be discharged into the collecting box 205 through the feeding pipe 202, so that the impurity removal box 104 is kept clean.

[0043] As shown in Figure 5 The right side of the separation box 1 is provided with a transmission mechanism one 4, which comprises a rectangular frame 401 fixedly installed on the right side of the separation box 1. A U-shaped plate 402 is slidably installed in the rectangular frame 401. A plurality of teeth 403 are fixedly installed on the front surface of the U-shaped plate 402. A gear 404 is fixedly sleeved on the corresponding rotating rod 107. The gear 404 is engaged with the plurality of teeth 403. Two adaptive springs 405 are fixedly installed on the top and bottom of the U-shaped plate 402, respectively. The ends of the plurality of adaptive springs 405 away from each other are fixedly connected with the rectangular frame 401. A T-shaped limiting plate 406 is fixedly installed on the right side of the U-shaped plate 402. The right end of the T-shaped limiting plate 406 extends to the outside of the rectangular frame 401 and is slidably connected with the rectangular frame 401.

[0044] When the U-shaped plate 402 rises or falls, the gear 404 is always in contact with the first tooth 403 or the last tooth 403. At this time, the adaptive spring 405 on the top inner wall or the bottom inner wall of the U-shaped plate 402 will be compressed and deformed due to the movement of the U-shaped plate 402. The adaptive spring 405 will always push the U-shaped plate 402 under the action of the elastic force of the adaptive spring 405, so that the first tooth 403 or the last tooth 403 does not move away from the gear 404, thereby ensuring that the continuous movement of the impurity removal box 104 is not affected when the U-shaped plate 402 stops moving.

[0045] As shown in Figure 2 The right side of the separation box 1 is provided with a transmission mechanism two 5, which comprises a rotating shaft 501 rotatably installed on the right side of the separation box 1. A belt pulley 502 is fixedly sleeved on the rotating shaft 501 and the rotating rod 107 close to the rectangular frame 401, respectively. A synchronous belt 503 is sleeved on the two belt pulleys 502. A rod disc 504 is fixedly installed on the right end of the rotating shaft 501. Two conical round rods 505 are slidably installed on the right side of the separation box 1. The left ends of the two conical round rods 505 extend into the separation box 1.

[0046] The rotating shaft 107 drives the rotating shaft 501 to rotate under the action of the pulley 502 and the synchronous belt 503, the rotating shaft 501 drives the belt rod disc 504 to rotate, and the two rods on the belt rod disc 504 touch the two conical cylindrical rods 505 when rotating, and the conical cylindrical rods 505 move into the separation tank 1 after the rods on the belt rod disc 504 touch the conical cylindrical rods 505.

[0047] As shown in Figure 2 , Figure 6 and Figure 7 , the separation tank 1 is provided with a screening mechanism 6, the screening mechanism 6 includes discharge slots 601 opened on the front and back of the separation tank 1, two arc-shaped screening plates 602 are arranged in the separation tank 1, the two arc-shaped screening plates 602 respectively penetrate the two discharge slots 601, the bottoms of the two arc-shaped screening plates 602 are respectively slidably installed with slide rods 603, the two slide rods 603 are fixedly connected with the separation tank 1, and a plurality of screening holes 604 are opened on the inner walls of the corresponding arc-shaped screening plates 602.

[0048] The arc-shaped screening plates 602 vibrate during the vibration process, which makes the silicon carbide particles on the arc-shaped screening plates 602 close to the impurity removal cylindrical tank 104 shake left and right, and the silicon carbide particles are dispersed during the shaking process, so that the fine silicon carbide particles are more smoothly separated and fall from the plurality of screening holes 604. During the continuous rotation of the belt rod disc 504, the two arc-shaped screening plates 602 repeatedly vibrate, which not only improves the separation effect of the fine silicon carbide particles, but also improves the discharging efficiency of the silicon carbide particles, avoids the accumulation of the silicon carbide particles due to slow discharging, and thus affects the separation effect of the silicon carbide particles.

[0049] As shown in Figure 7 , the two arc-shaped screening plates 602 are respectively provided with a vibration mechanism 7, the vibration mechanism 7 includes two vibration slide rods 701 fixedly installed on the outer walls of the arc-shaped screening plates 602, the mutually distal ends of the two vibration slide rods 701 extend out of the separation tank 1, circular blocks 702 are respectively fixedly sleeved on the two vibration slide rods 701, vibration springs 703 are respectively sleeved on the two vibration slide rods 701, the mutually distal ends of the two vibration springs 703 are respectively fixedly connected with the two circular blocks 702, and the mutually proximal ends of the two vibration springs 703 are fixedly connected with the separation tank 1.

[0050] The arc-shaped screening plates 602 drive the plurality of vibration slide rods 701 to move in the same direction, and the vibration springs 703 away from the rotating shaft 501 are compressed and deformed, after the rods on the belt rod disc 504 leave the conical cylindrical rods 505, the vibration springs 703 drive the two arc-shaped screening plates 602 to rebound and vibrate under the action of the elastic force.

[0051] As shown in Figures 1-8The superfine carbonized silicon powder purification device is shown, and the method steps are as follows:

[0052] S1: After the silicon carbide particles are poured into the separation box 1, the silicon carbide particles will flow into the impurity removal round box 104 through the feed inlet 110. The driving motor 106 is started, and the driving motor 106 drives the rotating rod 107 close to the driving motor 106 to rotate, the rotating rod 107 drives the circular plate 108 to rotate, the connecting rod 109 drives the impurity removal round box 104 to rotate in the plane, and the two T-shaped sliding blocks 102 will move up and down in the two T-shaped separation grooves 101 during the rotation of the impurity removal round box 104. The two fixed blocks 103 will continuously slide left and right in the two T-shaped sliding blocks 102, so as to ensure that the impurity removal round box 104 vertically rotates in the plane. The silicon carbide particles falling on the inner wall of the bottom of the impurity removal round box 104 will be continuously turned up during the rotation of the impurity removal round box 104, so as to avoid the impurities from blocking the impurity removal hole 105 of the bottom of the impurity removal round box 104. The movement of the impurity removal round box 104 will make the silicon carbide particles move up and down in a small amplitude;

[0053] S2: The silicon carbide particles filtered through the impurity removal hole 105 will fall on the arc-shaped screening plate 602 close to the impurity removal round box 104. The rotating rod 107 on the right side of the separation box 1 will rotate during the movement of the impurity removal round box 104. The rotating rod 107 will drive the rotating shaft 501 to rotate under the action of the belt pulley 502 and the synchronous belt 503. The rotating shaft 501 drives the rod disc 504 to rotate. The two rods on the rod disc 504 will touch the two conical round rods 505 during rotation. After the rods on the rod disc 504 touch the conical round rods 505, the conical round rods 505 will move into the separation box 1. The two conical round rods 505 will push the two arc-shaped screening plates 602 to move away from the rotating shaft 501. At this time, the arc-shaped screening plate 602 drives a plurality of vibrating sliding rods 701 to move in the same direction. The vibrating spring 703 away from the rotating shaft 501 will be compressed and deformed. After the rods on the rod disc 504 leave the conical round rods 505, the vibrating spring 703 will drive the two arc-shaped screening plates 602 to rebound and vibrate under the action of the elastic force. The arc-shaped screening plate 602 will make the silicon carbide particles on the arc-shaped screening plate 602 close to the impurity removal round box 104 shake left and right during the vibration, which will disperse the silicon carbide particles and make the fine silicon carbide particles more smoothly separate and fall from the plurality of screening holes 604. The two arc-shaped screening plates 602 will repeatedly vibrate during the continuous rotation of the rod disc 504;

[0054] S3: When the purification of the silicon carbide particles is finished, the driving motor 106 is reversed, so that the driving motor 106 drives the rotating rod 107 to rotate reversely, the rotating rod 107 drives the gear 404 to rotate, the gear 404 drives the L-shaped plate 402 to rise under the action of the plurality of teeth 403, the L-shaped plate 402 drives the ladder-shaped round rod 302 to rise, the ladder-shaped round rod 302 drives the L-shaped round rod 301 to rise, the L-shaped round rod 301 drives the conical rod block 203 in the discharging pipe 202 to rise, the conical rod block 203 drives the limiting hollow block 204 to rise, so that the conical rod block 203 leaves the discharging pipe 202, and at this time, the limiting hollow block 204 is still in the discharging pipe 202, since the impurity removal round box 104 continuously rotates in a plane, the limiting hollow block 204 is always in the discharging pipe 202 in the movement of the impurity removal round box 104, so that the conical rod block 203 cannot accurately enter the discharging pipe 202 in the process of descending, the L-shaped round rod 301 slides left and right in the ladder-shaped round rod 302 in the movement of the impurity removal round box 104, and simultaneously plays a limiting role, so as to ensure that the L-shaped round rod 301 and the ladder-shaped round rod 302 cannot be separated, after the conical rod block 203 leaves the discharging pipe 202, the impurities in the impurity removal round box 104 enter the discharging pipe 202 in the shaking of the impurity removal round box 104, and are discharged into the collecting box 205 through the discharging pipe 202;

[0055] S4: The driving motor 106 is in an open state, the rotating rod 107 continuously rotates, when the L-shaped plate 402 rises or falls, the gear 404 is always in contact with the first tooth 403 or the last tooth 403, at this time, the adaptive spring 405 on the top inner wall or the bottom inner wall of the L-shaped plate 402 is compressed and deformed due to the movement of the L-shaped plate 402, and always presses the L-shaped plate 402 under the action of the elastic force of the adaptive spring 405, so as to avoid that the first tooth 403 or the last tooth 403 leaves the gear 404, thereby ensuring that the continuous movement of the impurity removal round box 104 is not affected when the L-shaped plate 402 stops moving.

7. A method of using an ultra-fine silicon carbide micro powder purification device, comprising the ultra-fine silicon carbide micro powder purification device as described in claim 6, characterized in that, The steps are as follows: S1: After the silicon carbide particles are poured into the separation box (1), the silicon carbide particles will flow into the impurity removal round box (104) through the feed inlet (110). Start the drive motor (106), and the drive motor (106) will drive the rotating rod (107) near the drive motor (106) to rotate. The rotating rod (107) will drive the circular plate (108) to rotate. The circular plate (108) will drive the connecting rod (109) to rotate. The connecting rod (109) will drive the impurity removal round box (104) to rotate in a plane. During the rotation of the impurity removal round box (104), it will drive the two T-shaped sliders (102) to rotate in two directions. The impurity removal box (104) moves up and down within the T-shaped separation groove (101), and the impurity removal box (104) also drives the two fixed blocks (103) to slide left and right within the two T-shaped sliders (102), thereby ensuring that the impurity removal box (104) rotates vertically in a plane. During the plane rotation of the impurity removal box (104), the silicon carbide particles that have fallen on the bottom inner wall of the impurity removal box (104) will be continuously turned up, thereby preventing impurities from clogging the impurity removal hole (105) at the bottom of the impurity removal box (104). The movement of the impurity removal box (104) will cause the silicon carbide particles to turn up slightly. S2: Silicon carbide particles filtered through the impurity removal holes (105) fall onto the arc-shaped screening plate (602) near the impurity removal cylinder (104). During the movement of the impurity removal cylinder (104), the rotating rod (107) on the right side of the separation box (1) will rotate. The rotating rod (107) will drive the rotating shaft (501) to rotate under the action of the pulley (502) and the synchronous belt (503). The rotating shaft (501) will drive the rod-driven disc (504) to rotate. When the two rods on the rod-driven disc (504) rotate, they will touch the two conical rods (505). After the rods on the rod-driven disc (504) touch the conical rods (505), the conical rods (505) will move into the separation box (1). The two conical rods (505) will push the two arc-shaped screening plates (602) away from the rotating shaft (501) at the same time. As the arc screen plate (602) moves in the same direction, it drives several vibrating slide bars (701) to move in the same direction. The vibrating spring (703) away from the rotating shaft (501) will undergo compression deformation. After the rod on the rod-driven disc (504) leaves the conical rod (505), the vibrating spring (703) will drive the two arc screen plates (602) to rebound and generate vibration under the action of elastic force. During the vibration process, the silicon carbide particles on the arc screen plate (602) close to the impurity removal box (104) will sway left and right. During the swaying process, the silicon carbide particles will be dispersed, so that the fine silicon carbide particles can be separated and fall more smoothly from several screening holes (604). As the rod-driven disc (504) continues to rotate, the two arc screen plates (602) will repeatedly perform vibration motion. S3: After the silicon carbide particle purification is completed, reverse the drive motor (106), thereby causing the drive motor (106) to drive the rotating rod (107) to reverse. The rotating rod (107) drives the gear (404) to rotate. Under the action of several teeth (403), the gear (404) drives the C-shaped plate (402) to rise. The C-shaped plate (402) drives the trapezoidal round rod (302) to rise. The trapezoidal round rod (302) drives the L-shaped round rod (301) to rise. The L-shaped round rod (301) drives the conical rod block (203) in the discharge pipe (202) to rise. The conical rod block (203) drives the limiting hollow block (204) to rise, so that the conical rod block (203) leaves the discharge pipe (202). At this time, the limiting hollow block (204) is still in the discharge pipe (202). Due to the impurity removal box (104) The impurity removal box (104) will continue to rotate in a plane. During the movement of the impurity removal box (104), the limiting hollow block (204) will always be inside the discharge pipe (202) to prevent the conical rod block (203) from failing to accurately enter the discharge pipe (202) during the descent. When the impurity removal box (104) moves, the L-shaped rod (301) will slide left and right in the trapezoidal rod (302) and play a limiting role at the same time, ensuring that the L-shaped rod (301) and the trapezoidal rod (302) will not separate. After the conical rod block (203) leaves the discharge pipe (202), under the action of the conical inclined surface of the impurity removal box (104), the impurities in the impurity removal box (104) will enter the discharge pipe (202) during the shaking of the impurity removal box (104) and be discharged into the collection box (205) through the discharge pipe (202). S4: When the drive motor (106) is turned on, the rotating rod (107) will continue to rotate. When the convex plate (402) rises or falls, the gear (404) will always be in contact with the first tooth (403) or the last tooth (403). At this time, the adapter spring (405) on the inner wall of the top or bottom of the convex plate (402) will be compressed and deformed due to the movement of the convex plate (402). Under the elastic force of the adapter spring (405), it will always push against the convex plate (402) to prevent the first tooth (403) or the last tooth (403) from leaving the gear (404), thereby ensuring that the continuous movement of the impurity removal box (104) will not be affected when the convex plate (402) stops moving.
