[0002] Silicon carbide is an inorganic compound with the chemical formula SiC. It is composed of silicon and carbon, hence the name silicon carbide. Silicon carbide has a variety of crystal structures, including β-type (cubic) and α-type (hexagonal), usually dominated by β-type crystals. Silicon carbide is widely used in many fields due to its special physical and chemical properties.

[0003] In the process of purifying silicon carbide, impurities in silicon carbide particles need to be cleaned and screened out.

The bottom end of the ladder-shaped circular rod extends into the impurity removal circular box. The right end of the L-shaped circular rod extends into the ladder-shaped circular rod and is slidably connected with the ladder-shaped circular rod.

[0008] Further, a transmission mechanism one is arranged on the right side of the separation box. The transmission mechanism one includes a rectangular frame fixedly installed on the right side of the separation box. A C-shaped plate is slidably installed in the rectangular frame. A plurality of teeth are fixedly installed on the front surface of the C-shaped plate. A gear is fixedly sleeved on the corresponding rotating rod. The gear meshes with the plurality of teeth. Two adaptation springs are respectively fixedly installed at the top and bottom of the C-shaped plate. One end of each of the plurality of adaptation springs away from each other is fixedly connected with the rectangular frame. A T-shaped limiting plate is fixedly installed on the right side of the C-shaped plate. The right end of the T-shaped limiting plate extends out of the rectangular frame and is slidably connected with the rectangular frame.

[0009] Further, a transmission mechanism two is arranged on the right side of the separation box. The transmission mechanism two includes a rotating shaft rotatably installed on the right side of the separation box. A pulley is respectively fixedly sleeved on the rotating shaft and the rotating rod close to the rectangular frame. A synchronous belt is sleeved on the two pulleys. A belt rod disc is fixedly installed at the right end of the rotating shaft. Two conical circular rods are slidably installed on the right side of the separation box. The left ends of the two conical circular rods both extend into the separation box.

[0010] Further, a screening mechanism is arranged on the separation box. The screening mechanism includes discharge grooves opened on the front and back surfaces of the separation box. Two arc-shaped screening plates are arranged in the separation box. The two arc-shaped screening plates respectively penetrate through the two discharge grooves. Slide rods are respectively slidably installed at the bottoms of the two arc-shaped screening plates. The two slide rods are both fixedly connected with the separation box. A plurality of screening holes are opened on the inner walls of the corresponding arc-shaped screening plates.

[0011] Furthermore, a vibration mechanism is respectively provided on the two arc-shaped screening plates, and the vibration mechanism includes two vibration slide bars fixedly mounted on the outer wall of the arc-shaped screening plate, and the ends of the two vibration slide bars away from each other extend outside the separation box, and circular blocks are respectively fixedly sleeved on the two vibration slide bars, and vibration springs are respectively sleeved on the two vibration slide bars, and the ends of the two vibration springs away from each other are respectively fixedly connected to the two circular blocks, and the ends of the two vibration springs close to each other are fixedly connected to the separation box.

[0012] Furthermore, the ultra-fine silicon carbide powder purification device has the following steps: S1: After the silicon carbide particles are poured into the separation box, the silicon carbide particles will flow into the impurity removal circular box through the feed port, and the driving motor is started. The driving motor drives the rotating rod close to the driving motor to rotate, and the rotating rod drives the circular plate to rotate, and the circular plate drives the connecting rod to rotate, and the connecting rod drives the impurity removal circular box to rotate in a plane. During the rotation of the impurity removal circular box, the two T-shaped sliders will be driven to move up and down in the two T-shaped separation grooves, and the impurity removal circular box will also drive the two fixed blocks to continuously slide left and right in the two T-shaped sliders, so as to ensure that the impurity removal circular box performs a vertical plane rotation movement. During the plane rotation of the impurity removal circular box, the silicon carbide particles that fall on the inner wall of the bottom of the impurity removal circular box will be continuously turned up, so as to prevent the impurities from clogging the impurity removal holes at the bottom of the impurity removal circular box. The movement of the impurity removal circular box will cause the silicon carbide particles to turn up slightly; S2: The silicon carbide particles filtered through the impurity removal holes will fall onto the arc-shaped screening plate near the impurity removal circular box. During the movement of the impurity removal circular box, the rotating rod on the right side of the separation box will be driven to rotate. The rotating rod will drive the rotating shaft to rotate under the action of the pulley and the synchronous belt. The rotating shaft drives the rod disc to rotate. The two rods on the rod disc will touch the two conical rods when rotating. After the rods on the rod disc touch the conical rods, the conical rods will move into the separation box. The two conical rods will push the two arc-shaped screening plates to move away from the rotating shaft at the same time. At this time, the arc-shaped screening plates drive the The two vibrating slide bars move in the same direction, and the vibrating spring away from the rotating shaft will be compressed and deformed. After the rod on the rod disc leaves the conical rod, the vibrating spring will drive the two arc-shaped screening plates to rebound and vibrate under the action of elastic force. The arc-shaped screening plates will make the silicon carbide particles on the arc-shaped screening plates close to the impurity removal box shake left and right during the vibration process. The silicon carbide particles will be dispersed during the shaking process, so that the fine silicon carbide particles can be separated and fall from several screening holes more smoothly. The two arc-shaped screening plates will repeat the vibrating motion during the continuous rotation of the rod disc. S3: After the purification of the silicon carbide particles is completed, reverse the driving motor, so that the driving motor drives the rotating rod to reverse. The rotating rod drives the gear to rotate. Under the action of several teeth, the gear drives the U-shaped plate to rise. The U-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 belt rod block in the discharge pipe to rise. The conical belt rod block drives the limit hollow block to rise, so that the conical belt rod block leaves the discharge pipe. At this time, the limit hollow block is still in the discharge pipe. Since the impurity removal round box will continue to rotate in a plane, during the movement of the impurity removal round box, the limit hollow block is always in the discharge pipe, preventing it from failing to accurately enter the discharge pipe during the descent of the conical belt rod block. When the impurity removal round box moves, the L-shaped round rod will slide left and right in the ladder-shaped round rod and play a limiting role at the same time, ensuring that the L-shaped round rod and the ladder-shaped round rod will not separate. After the conical belt rod block leaves the discharge pipe, under the action of the conical inclined surface of the impurity removal round box, the impurities in the impurity removal round box will enter the discharge pipe during the shaking of the impurity removal round box, and the impurities will be discharged into the collection box through the discharge pipe; S4: When the driving motor is in the on state, the rotating rod will continue to rotate. When the U-shaped plate rises or falls, the gear will always be in contact with the first tooth or the last tooth. At this time, the matching spring on the inner wall of the top or bottom of the U-shaped plate will be compressed and deformed due to the movement of the U-shaped plate. Under the elastic force of the matching spring, it will always push against the U-shaped plate, preventing the first tooth or the last tooth from leaving the gear, so as to ensure that the continuous movement of the impurity removal round box will not be affected when the U-shaped plate stops moving.

[0013] The present invention has the following beneficial effects: (1) For the ultra-fine silicon carbide micro-powder cleaning and purification device of the present invention, after pouring the silicon carbide particles into the separation box, the silicon carbide particles will flow into the impurity removal round box along the feed port. Start the driving motor, and the driving motor drives the rotating rod close to the driving motor to rotate. The rotating rod drives the round plate to rotate. The round plate drives the connecting rod to rotate. The connecting rod drives the impurity removal round box to rotate in a plane. During the rotation of the impurity removal round box, it will drive two T-shaped sliders to move up and down in two T-shaped separation grooves. The impurity removal round box will also drive two fixed blocks to continuously slide left and right in the two T-shaped sliders, so as to ensure that the impurity removal round box rotates vertically in a plane. During the planar rotation of the impurity removal round box, the silicon carbide particles falling on the inner wall of the bottom of the impurity removal round box will be continuously turned up, thus preventing impurities from blocking the impurity removal holes at the bottom of the impurity removal round box. The movement of the impurity removal round box will cause the silicon carbide particles to turn up slightly, thereby reducing the surface damage of the silicon carbide particles caused by the mechanical force generated by the movement of the impurity removal round box, and maintaining the overall strength and durability of the silicon carbide particles; (2)In a high-precision silicon carbide micropowder cleaning and purification device of the present invention, the silicon carbide particles filtered through the impurity removal holes will fall onto the arc-shaped screening plate near the impurity removal circular box. During the movement of the impurity removal circular box, the rotating rod on the right side of the separation box will be driven to rotate. Under the action of the pulley and synchronous belt, the rotating rod will drive the rotating shaft to rotate, and the rotating shaft will drive the belt rod disc to rotate. When the two rods on the belt rod disc rotate, they will touch the two conical circular rods. After the rod on the belt rod disc touches the conical circular rod, the conical circular rod will move into the separation box. The two conical circular rods will push the two arc-shaped screening plates to move away from the rotating shaft at the same time. At this time, the arc-shaped screening plate will drive a number of vibrating slide rods to move in the same direction, and the vibrating springs away from the rotating shaft will undergo compressive deformation. After the rod on the belt rod disc leaves the conical circular rod, the vibrating springs will drive the two arc-shaped screening plates to bounce back and vibrate under the action of elastic force. During the vibration of the arc-shaped screening plate, the silicon carbide particles on the arc-shaped screening plate near the impurity removal circular box will shake left and right. During the shaking process, the silicon carbide particles will be dispersed, so that the fine silicon carbide particles can fall more smoothly from a number of screening holes. During the continuous rotation of the belt rod disc, the two arc-shaped screening plates will repeat the vibration movement, which can not only improve the separation effect of fine silicon carbide particles, but also improve the discharging efficiency of silicon carbide particles, avoiding the slow discharging of silicon carbide particles resulting in accumulation, thus affecting the separation effect of silicon carbide particles; (3)In a high-precision silicon carbide micropowder cleaning and purification device of the present invention, when the purification of silicon carbide particles is completed, reverse the driving motor, so that the driving motor drives the rotating rod to reverse. The rotating rod drives the gear to rotate. Under the action of a number of teeth, the gear drives the C-shaped plate to rise. The C-shaped plate drives the ladder-shaped circular rod to rise. The ladder-shaped circular rod drives the L-shaped circular rod to rise. The L-shaped circular rod drives the conical belt rod block in the discharge pipe to rise. The conical belt rod block drives the limit hollow block to rise, so that the conical belt rod block leaves the discharge pipe. At this time, the limit hollow block is still in the discharge pipe. Since the impurity removal circular box will continue to rotate in a plane, during the movement of the impurity removal circular box, the limit hollow block is always in the discharge pipe, avoiding the situation that the conical belt rod block cannot accurately enter the discharge pipe during the descending process. When the impurity removal circular box moves, the L-shaped circular rod will slide left and right in the ladder-shaped circular rod and play a limiting role at the same time, ensuring that the L-shaped circular rod and the ladder-shaped circular rod will not separate. After the conical belt rod block leaves the discharge pipe, under the action of the conical inclined surface of the impurity removal circular box, the impurities in the impurity removal circular box will enter the discharge pipe during the shaking of the impurity removal circular box and be discharged into the collection box through the discharge pipe, ensuring the cleanliness of the impurity removal circular box; (4) The present invention provides an ultra-fine silicon carbide micropowder purification device. When the driving motor is turned on, the rotating rod will continue to rotate. When the shaped plate rises or falls, the gear will always be in contact with the first tooth or the last tooth. At this time, the adapter spring on the top inner wall or the bottom inner wall of the shaped plate will be compressed and deformed due to the movement of the shaped plate. Under the elastic force of the adapter spring, it will always press against the shaped plate to prevent the first tooth or the last tooth from leaving the gear, thereby ensuring that when the shaped plate stops moving, it will not affect the continuous movement of the impurity removal box.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1-Figure 8 As shown in the figure, the present invention is a superfine silicon carbide micropowder cleaning and purification device, including a separation box 1. An impurity removal mechanism 100 is provided on the separation box 1. The impurity removal mechanism 100 includes T-shaped separation grooves 101 opened on the front inner wall and the back inner wall of the separation box 1. T-shaped sliders 102 are respectively slidably installed in the two T-shaped separation grooves 101. Fixed blocks 103 are respectively slidably installed on the two T-shaped sliders 102. One ends of the two fixed blocks 103 close to each other respectively extend outside the two T-shaped sliders 102. An impurity removal circular box 104 is fixedly installed on the two fixed blocks 103. The bottom inner wall of the impurity removal circular box 104 is a conical inclined plane. It also includes: A plurality of impurity removal holes 105 are provided on the inner wall at the bottom of the impurity removal circular box 104, a driving motor 106 is fixedly installed on the left side of the separation box 1, and rotating rods 107 are rotatably installed on the left and right sides of the separation box 1, and the ends of the two rotating rods 107 close to each other extend into the separation box 1, and the output shafts of the driving motor 106 are fixedly connected to the corresponding rotating rods 107, and circular plates 108 are fixedly installed on the ends of the two rotating rods 107 close to each other, and connecting rods 109 are fixedly installed on the sides 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 to the impurity removal circular box 104, and a feed port 110 is fixedly installed on the top of the separation box 1.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a discharge mechanism 2 is provided on the front of the separation box 1, and the discharge mechanism 2 includes a discharge trough 201 opened on the front of the separation box 1, a discharge pipe 202 is fixedly installed on the bottom of the impurity removal circular box 104, the end of the discharge pipe 202 passes through the discharge trough 201 and is adapted to the discharge trough 201, a conical rod block 203 is slidably installed in the discharge pipe 202, the top of the conical rod block 203 extends into the impurity removal circular box 104, a limited hollow block 204 is fixedly installed on the bottom of the conical rod block 203, and the limited hollow block 204 is slidably connected to the discharge pipe 202, and a collecting box 205 is fixedly installed on the front of the separation box 1.

[0021] 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, and at this time the limiting hollow block 204 is still in the discharge pipe 202. Since the impurity removal box 104 will continue to rotate in a plane, the limiting hollow block 204 is always in the discharge pipe 202 during the movement of the impurity removal box 104, avoiding the conical rod block 203 from being unable to accurately enter the discharge pipe 202 during the descending process.

[0022] like Figure 2 and Figure 3 As shown, an adapting mechanism 3 is provided at the top of the conical belt rod block 203, and the adapting mechanism 3 includes an L-shaped round rod 301 fixedly installed on the top of the conical belt rod block 203, and a ladder-type round rod 302 is slidably installed on the separation box 1, and the bottom end of the ladder-type round rod 302 extends into the impurity removal round box 104, and the right end of the L-shaped round rod 301 extends into the ladder-type round rod 302 and is slidably connected with the ladder-type round rod 302.

[0023] When the impurity removal circular box 104 moves, the L-shaped circular rod 301 will slide left and right within the ladder-shaped circular rod 302 while playing a limiting role to ensure that the L-shaped circular rod 301 and the ladder-shaped circular rod 302 will not separate. After the conical belt rod block 203 leaves the discharge pipe 202, under the action of the conical inclined surface of the impurity removal circular box 104, the impurities in the impurity removal circular box 104 will enter the discharge pipe 202 during the shaking of the impurity removal circular box 104, and the impurities will be discharged into the collection box 205 through the discharge pipe 202 to ensure the cleanliness of the impurity removal circular box 104.

[0024] As Figure 5 shown, a transmission mechanism one 4 is arranged on the right side of the separation box 1. The transmission mechanism one 4 includes a rectangular frame 401 fixedly installed on the right side of the separation box 1. A U-shaped plate 402 is slidably installed within the rectangular frame 401. A number 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 meshes with the number of teeth 403. Two matching springs 405 are respectively fixedly installed on the top and bottom of the U-shaped plate 402. One ends of the number of matching springs 405 away from each other are fixedly connected to 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 outside the rectangular frame 401 and is slidably connected to the rectangular frame 401.

[0025] When the U-shaped plate 402 rises or falls, the gear 404 will always contact the first tooth 403 or the last tooth 403. At this time, the matching spring 405 on the inner wall of the top or bottom of the U-shaped plate 402 will undergo compressive deformation due to the movement of the U-shaped plate 402. Under the elastic force of the matching spring 405, it will always push against the U-shaped 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 circular box 104 will not be affected when the U-shaped plate 402 stops moving.

[0026] As Figure 2 shown, a transmission mechanism two 5 is arranged on the right side of the separation box 1. The transmission mechanism two 5 includes a rotating shaft 501 rotatably installed on the right side of the separation box 1. 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 pulleys 502. A belt rod disc 504 is fixedly installed on the right end of the rotating shaft 501. Two conical circular rods 505 are slidably installed on the right side of the separation box 1. The left ends of the two conical circular rods 505 both extend into the separation box 1.

[0027] The rotating rod 107 drives the rotating shaft 501 to rotate under the action of the pulley 502 and the synchronous belt 503, and the rotating shaft 501 drives the rod disk 504 to rotate. The two rods on the rod disk 504 will touch the two conical rods 505 when rotating. After the rods on the rod disk 504 touch the conical rods 505, the conical rods 505 will move into the separation box 1.

[0028] like Figure 2 , Figure 6 and Figure 7 As shown, a screening mechanism 6 is provided on the separation box 1, and the screening mechanism 6 includes discharge troughs 601 opened on the front and back of the separation box 1, and two arc-shaped screening plates 602 are provided in the separation box 1, and the two arc-shaped screening plates 602 respectively penetrate the two discharge troughs 601, and slide rods 603 are slidably installed on the bottom of the two arc-shaped screening plates 602, respectively, and the two slide rods 603 are fixedly connected to the separation box 1, and a plurality of screening holes 604 are opened on the inner wall of the corresponding arc-shaped screening plate 602.

[0029] The arc-shaped screening plate 602 will cause the silicon carbide particles on the arc-shaped screening plate 602 close to the impurity removal box 104 to shake left and right during the vibration process, and the silicon carbide particles will be dispersed during the shaking process, so that the fine silicon carbide particles can be separated and fall from several screening holes 604 more smoothly. During the continuous rotation of the rod disc 504, the two arc-shaped screening plates 602 will repeat the vibrating motion, which can not only improve the separation effect of fine silicon carbide particles, but also improve the discharge efficiency of silicon carbide particles, and avoid the accumulation of silicon carbide particles due to slow discharge, thereby affecting the separation effect of silicon carbide particles.

[0030] like Figure 7 As shown, a vibration mechanism 7 is respectively provided on the two arc-shaped screening plates 602, and the vibration mechanism 7 includes two vibration slide bars 701 fixedly mounted on the outer wall of the arc-shaped screening plate 602, and the ends of the two vibration slide bars 701 away from each other extend to the outside of the separation box 1, and circular blocks 702 are respectively fixedly sleeved on the two vibration slide bars 701, and vibration springs 703 are respectively sleeved on the two vibration slide bars 701, and the ends of the two vibration springs 703 away from each other are respectively fixedly connected to the two circular blocks 702, and the ends of the two vibration springs 703 close to each other are both fixedly connected to the separation box 1.

[0031] The arc-shaped screening plate 602 drives several vibrating slide bars 701 to move in the same direction, and the vibration spring 703 away from the rotating shaft 501 will be compressed and deformed. After the rod on the rod disk 504 leaves the conical rod 505, the vibration spring 703 will drive the two arc-shaped screening plates 602 to rebound and vibrate under the action of elastic force.

[0032] like Figure 1-8The device for purifying ultra-fine silicon carbide powder is shown, and the method 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 box 104 through the feed port 110, and the drive motor 106 is started. The drive motor 106 drives the rotating rod 107 close to the drive motor 106 to rotate, and the rotating rod 107 drives the circular plate 108 to rotate, and the circular plate 108 drives the connecting rod 109 to rotate, and the connecting rod 109 drives the impurity removal box 104 to rotate in a plane. During the rotation of the impurity removal box 104, the two T-shaped sliders 102 will be driven to rotate between the two T-shaped separation boxes. The impurity removal box 104 moves up and down in the groove 101, and the two fixed blocks 103 continuously slide left and right in the two T-shaped sliders 102, so as to ensure that the impurity removal box 104 performs a vertical plane rotation movement. During the plane rotation of the impurity removal box 104, the silicon carbide particles that fall on the inner wall of the bottom of the impurity removal box 104 will be continuously turned up, so as to prevent the impurities from clogging the impurity removal holes 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: The silicon carbide particles filtered through the impurity removal holes 105 will fall onto the arc-shaped screening plate 602 close to the impurity removal circular box 104. During the movement of the impurity removal circular box 104, the rotating rod 107 on the right side of the separation box 1 will be driven to 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 drives the rod-belt disc 504 to rotate. The two rods on the rod-belt disc 504 will touch the two conical rods 505 when rotating. After the rods on the rod-belt 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 to move away from the rotating shaft 501 at the same time. When the arc-shaped screening plate 602 drives several vibration slide bars 701 to move in the same direction, the vibration spring 703 away from the rotating shaft 501 will be compressed and deformed, and after the rod on the rod-carrying disc 504 leaves the conical rod 505, the vibration spring 703 will drive the two arc-shaped screening plates 602 to rebound and vibrate under the action of elastic force. In the process of generating vibration, 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, and in the process of shaking, the silicon carbide particles will be dispersed, so that the fine silicon carbide particles can be separated and fall from several screening holes 604 more smoothly. In the continuous rotation of the rod-carrying disc 504, the two arc-shaped screening plates 602 will repeat the vibration movement; S3: After the purification of the silicon carbide particles is completed, reverse the drive motor 106, so that the drive motor 106 drives the rotating rod 107 to reverse. The rotating rod 107 drives the gear 404 to rotate. Driven by a number of teeth 403, the gear 404 drives the U-shaped plate 402 to rise. The U-shaped plate 402 drives the stepped round rod 302 to rise. The stepped round rod 302 drives the L-shaped round rod 301 to rise. The L-shaped round rod 301 drives the tapered belt rod block 203 in the discharge pipe 202 to rise. The tapered belt rod block 203 drives the limit hollow block 204 to rise, causing the tapered belt rod block 203 to leave the discharge pipe 202. At this time, the limit hollow block 204 is still in the discharge pipe 202. Since the impurity removal circular box 104 will continue to rotate in a plane, during the movement of the impurity removal circular box 104, the limit hollow block 204 is always in the discharge pipe 202, preventing the tapered belt rod block 203 from failing to accurately enter the discharge pipe 202 during the descent. When the impurity removal circular box 104 moves, the L-shaped round rod 301 will slide left and right in the stepped round rod 302 and play a limiting role at the same time, ensuring that the L-shaped round rod 301 and the stepped round rod 302 will not separate. After the tapered belt rod block 203 leaves the discharge pipe 202, under the action of the tapered inclined surface of the impurity removal circular box 104, the impurities in the impurity removal circular box 104 will enter the discharge pipe 202 during the shaking of the impurity removal circular box 104, and the impurities will be discharged into the collection box 205 through the discharge pipe 202; S4: When the drive motor 106 is in the on state, the rotating rod 107 will continue to rotate. When the U-shaped 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 adaptor spring 405 on the inner wall of the top or bottom of the U-shaped plate 402 will be compressed and deformed due to the movement of the U-shaped plate 402. Under the elastic force of the adaptor spring 405, it will always push against the U-shaped plate 402, preventing the first tooth 403 or the last tooth 403 from leaving the gear 404, so as to ensure that the continuous movement of the impurity removal circular box 104 will not be affected when the U-shaped plate 402 stops moving.

8. A method for using an ultra-fine silicon carbide micropowder cleaning and purification device, using the ultra-fine silicon carbide micropowder cleaning and purification device as claimed in claim 7, 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 flow into the impurity removal box (104) through the feed port (110), and the drive motor (106) is started. The drive motor (106) drives the rotating rod (107) near the drive motor (106) to rotate, and the rotating rod (107) drives the circular plate (108) to rotate. The circular plate (108) drives the connecting rod (109) to rotate, and the connecting rod (109) drives the impurity removal box (104) to rotate in a plane. During the rotation of the impurity removal box (104), the two T-shaped sliders (102) are driven to rotate on both sides. The impurity removal box (104) moves up and down in the two T-shaped separation grooves (101), and the two fixed blocks (103) are driven to slide left and right in the two T-shaped slide blocks (102), thereby ensuring that the impurity removal box (104) performs a vertical planar rotation movement. During the planar rotation of the impurity removal box (104), the silicon carbide particles that fall on the inner wall of the bottom of the impurity removal box (104) are continuously turned up, thereby preventing the impurities from clogging the impurity removal holes (105) at the bottom of the impurity removal box (104). The movement of the impurity removal box (104) causes the silicon carbide particles to turn up slightly; S2: The silicon carbide particles filtered through the impurity removal holes (105) will fall onto the arc-shaped screening plate (602) near the impurity removal circular box (104). During the movement of the impurity removal circular box (104), the rotating rod (107) on the right side of the separation box (1) will be driven to 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) drives the rod disc (504) to rotate. The two rods on the rod disc (504) will touch the two conical rods (505) when rotating. After the rods on the rod 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. The arc-shaped screening plate (602) moves in the same direction, and the vibration slide bars (701) move in the same direction. The vibration spring (703) away from the rotating shaft (501) is compressed and deformed. After the rod on the rod disc (504) leaves the conical rod (505), the vibration spring (703) drives the two arc-shaped screening plates (602) to rebound and vibrate under the action of elastic force. The arc-shaped screening plate (602) causes the silicon carbide particles on the arc-shaped screening plate (602) close to the impurity removal box (104) to shake left and right during the vibration. The silicon carbide particles are dispersed during the shaking process, so that the fine silicon carbide particles are separated and fall from the several screening holes (604) more smoothly. The two arc-shaped screening plates (602) repeat the vibration movement while the rod disc (504) continues to rotate. S3: After the purification of the silicon carbide particles is completed, reverse the drive motor (106), so that the drive motor (106) drives 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 U-shaped plate (402) to rise. The U-shaped plate (402) drives the stepped round rod (302) to rise. The stepped round rod (302) drives the L-shaped round rod (301) to rise. The L-shaped round rod (301) drives the tapered belt rod block (203) in the discharge pipe (202) to rise. The tapered belt rod block (203) drives the limit hollow block (204) to rise, so that the tapered belt rod block (203) leaves the discharge pipe (202). At this time, the limit hollow block (204) is still in the discharge pipe (202). Since the impurity removal round box (104) will continue to rotate in a plane, during the movement of the impurity removal round box (104), the limit hollow block (204) is always in the discharge pipe (202), preventing the tapered belt rod block (203) from failing to accurately enter the discharge pipe (202) during the descent. When the impurity removal round box (104) moves, the L-shaped round rod (301) will slide left and right in the stepped round rod (302) and play a limiting role at the same time, ensuring that the L-shaped round rod (301) and the stepped round rod (302) will not separate. After the tapered belt rod block (203) leaves the discharge pipe (202), under the action of the tapered inclined surface of the impurity removal round box (104), the impurities in the impurity removal round box (104) will enter the discharge pipe (202) during the shaking of the impurity removal round box (104), and the impurities will be discharged into the collection box (205) through the discharge pipe (202); S4: When the drive motor (106) is in the on state, the rotating rod (107) will continue to rotate. When the U-shaped plate (402) rises or falls, the gear (404) will always contact the first tooth (403) or the last tooth (403). At this time, the adapter spring (405) on the top inner wall or bottom inner wall of the U-shaped plate (402) will be compressed due to the movement of the U-shaped plate (402). Under the elastic force of the adapter spring (405), it will always push against the U-shaped plate (402), preventing the first tooth (403) or the last tooth (403) from leaving the gear (404), so as to ensure that the continuous movement of the impurity removal round box (104) will not be affected when the U-shaped plate (402) stops moving.
