Description
Technical Field
[0001] The present invention relates to the technical field of mechanical engineering. Specifically, it relates to a preparation device and process for a high-energy composite functional structural material. Background Art
[0002] A high-energy composite functional structural material refers to a class of advanced materials that combine multiple materials through composite technology, possessing both structural properties such as high strength and high toughness, and integrating special functions such as electrical conductivity, thermal conductivity, high temperature resistance, and electromagnetic shielding. Such materials have important applications in fields such as aerospace, electronic devices, and new energy. The main types and typical materials include silicon carbide fiber-reinforced ceramics, which can withstand high temperatures (up to over 1600 °C) and are used in hot-end components of aeroengines. At the same time, they have antioxidant functions. When producing and preparing them, silicon carbide blocks need to be crushed, and a crusher is required.
[0003] Currently, when existing silicon carbide crushers are in use, the following defects exist:
[0004] Firstly, silicon carbide crushers generally use a rotating crushing roller with teeth to extrude and crush silicon carbide blocks. However, the crushing roller is generally an integral whole. During long-term use, the teeth on the crushing roller are inevitably worn or broken. After the teeth are worn or broken, they cannot well crush the silicon carbide blocks. Since the crushing roller is an inseparable whole, when wanting to repair the teeth, one can choose to weld new teeth on the crushing roller, but the original crushing strength of the teeth cannot be restored. One can also choose to replace the entire crushing roller, but the economic cost is very high and it is not very practical.
[0005] Secondly, the number of teeth on the existing crushing roller is fixed. If one wants to adjust the particle size of the crushed silicon carbide and screen out a suitable particle size, generally, by increasing the rotation speed of the crushing roller or repeatedly and circularly crushing the silicon carbide blocks, the above purpose can be achieved. However, increasing the rotation speed of the crushing roller will consume more energy, and repeatedly and circularly crushing the silicon carbide blocks will significantly increase the crushing time of the silicon carbide, and the crushing efficiency is low. In view of this, we propose a preparation device and process for a high-energy composite functional structural material. Summary of the Invention
[0006] The present invention aims at the technical problems existing in the prior art and provides a preparation device for a high-energy composite functional structural material to solve the problems that since the crushing roller is an inseparable whole, when wanting to repair the teeth, one can choose to weld new teeth on the crushing roller, but the original crushing strength of the teeth cannot be restored, one can also choose to replace the entire crushing roller, but the economic cost is very high, and increasing the rotation speed of the crushing roller will consume more energy, and repeatedly and circularly crushing the silicon carbide blocks will significantly increase the crushing time of the silicon carbide, and the crushing efficiency is low.
[0007] To solve the above technical problems, one of the objectives of the present invention is as follows. It includes a frame. At one end of the top of the frame, two symmetrically distributed driving devices for generating axial force are fixedly arranged. At the other end of the top of the frame, an equipment box is fixedly arranged. The bottom of the equipment box is fixedly communicated with a blanking channel. It is characterized in that: inside the equipment box, two crushing mechanisms for crushing silicon carbide blocks are symmetrically and rotatably arranged. The two crushing mechanisms are respectively connected to the output ends of the two driving devices, and the crushing mechanisms are designed modularly, forming multiple crushing units, which can be disassembled, replaced point by point or in strips, and the size of silicon carbide particles can be adjusted. At the bottom of the blanking channel, a screening mechanism for screening silicon carbide particles is arranged. The screening mechanism generates vibration force to shake, continuously crushes the silicon carbide particles, screens and stratifies the silicon carbide particles to distinguish silicon carbide with different particle sizes.
[0008] The beneficial effects of the present invention are as follows:
[0009] 1) In the preparation equipment of this high-energy composite functional structural material, two driving devices drive two crushing mechanisms to rotate. The crushing mechanisms generate axial force, drive the crushing units to rotate, and the crushing units rotate at high speed to crush the silicon carbide blocks. If a crushing unit is damaged, the crushing unit can be disassembled and replaced point by point or in strips. The new crushing unit has complete crushing strength, which improves the crushing efficiency. Moreover, instead of replacing the entire crushing mechanism, only some crushing units need to be replaced, which is beneficial to significantly reduce the economic cost and has strong practicability.
[0010] 2) In the preparation equipment of this high-energy composite functional structural material, by regularly reducing or increasing the number of crushing units on the crushing mechanism, the number of crushing units on the surface of the crushing mechanism can be changed. In this way, the number of times the crushing units crush the silicon carbide blocks can be reduced or increased, so as to achieve the purpose of adjusting the particle size of the silicon carbide particles. There is no need to increase the rotation speed of the crushing mechanism to save energy, nor is it necessary to repeatedly and circularly crush the silicon carbide blocks to reduce the crushing time of the silicon carbide, which is beneficial to improving the crushing efficiency. And in cooperation with the screening mechanism to generate vibration, not only can the silicon carbide blocks that are cracked but not split by the impact of the crushing mechanism be continuously crushed, further improving the crushing effect, but also the silicon carbide particles can be stratified to screen out silicon carbide particles with different particle sizes.
[0011] As a further improvement of this technical solution, the crushing mechanism includes a roller body. The roller body is rotatably arranged inside the equipment box, and one end of it is fixedly connected to the output end of the driving device. A plurality of uniformly distributed annular grooves are formed on the surface of the roller body, and the crushing units are arranged in the annular grooves;
[0012] The axis of the annular groove coincides with the axis of the roller body. After the crushing unit is installed in the annular groove, the distance of the crushing unit from the axis of the annular groove is the same, so that the impact effects of different crushing units on the silicon carbide block are the same.
[0013] The beneficial effect of adopting the above further solution is that by generating an axial force through the driving device, the roller body can be driven to rotate at a high speed, and then the crushing unit on the roller body can be driven to rotate, so as to crush the silicon carbide block. When the crushing unit is damaged, the damaged crushing unit can be removed and a new one can be replaced, without replacing the entire roller body, reducing the economic cost. And if it is necessary to adjust the particle size of the silicon carbide particles, regularly removing the crushing units from the annular groove can reduce or increase the contact times between the crushing units and the silicon carbide, so as to achieve the purpose of adjusting the particle size of the silicon carbide particles.
[0014] As a further improvement of the technical solution, the crushing unit includes two arc-shaped strips. Both of the two arc-shaped strips are fixedly arranged in the same annular groove through a plurality of first bolts. A plurality of mounting grooves distributed in an arc shape are formed on the outer wall of the arc-shaped strip. A crushing tooth for crushing the silicon carbide block is fixedly arranged in the mounting groove through a second bolt.
[0015] The axis of the arc-shaped strip coincides with the axis of the annular groove, so that the positions of different arc-shaped strips from the axis of the roller body are the same, and the crushing effects of different arc-shaped strips and crushing teeth on the silicon carbide block are basically the same.
[0016] The beneficial effect of adopting the above further solution is that by loosening or tightening the first bolts to disassemble and assemble the arc-shaped strips, and loosening or tightening the second bolts to disassemble and assemble the crushing teeth, when the crushing teeth are worn or broken due to long-term impact on the silicon carbide block, a new arc-shaped strip or crushing tooth can be replaced to restore the initial crushing strength of the crushing teeth, without replacing the entire roller body. And if it is necessary to adjust the particle size of the crushed silicon carbide block, a certain number of arc-shaped strips and crushing teeth can be regularly taken out from different annular grooves, or a certain number of arc-shaped strips and crushing teeth can be reinstalled and fixed in the idle annular grooves through the first bolts and the second bolts to reduce or increase the number of arc-shaped strips and crushing teeth, so as to achieve the purpose of adjusting the particle size of the crushed silicon carbide block. The more the number of arc-shaped strips and crushing teeth arranged regularly on the roller body, the smaller the particle size of the particles obtained by hitting the silicon carbide block, and vice versa, the larger the particle size of the silicon carbide particles obtained.
[0017] As a further improvement of the technical solution, the screening mechanism includes two fixing plates. One ends of the two fixing plates are respectively fixedly arranged on both sides of the blanking channel. A sliding plate is movably arranged on the top of each fixing plate through a plurality of elastic members. One ends of the two sliding plates are fixedly arranged with the same screening box.
[0018] The beneficial effect of adopting the above further solution is that by generating driving force by the screening mechanism itself to drive the screening box and the slide plate to vibrate, the silicon carbide blocks falling into the screening box from the blanking channel can be driven to vibrate, so that the silicon carbide blocks with cracks but not cracked continue to break, enhancing the crushing effect, and preparing to screen silicon carbide particles of different particle sizes to make them stratified.
[0019] As a further improvement of this technical solution, a plurality of inclined screening plates are fixedly arranged inside the screening box, and the plurality of screening plates are uniformly arranged from top to bottom;
[0020] The pore diameters on the plurality of screening plates decrease successively from top to bottom.
[0021] The beneficial effect of adopting the above further solution is that by driving the plurality of screening plates to vibrate through the vibration of the screening box, the silicon carbide particles of different particle sizes respectively pass through each screening plate, and the silicon carbide particles of a specific particle size continuously roll down along the surface of the corresponding screening plate, achieving the purpose of screening silicon carbide particles of different particle sizes and stratifying them.
[0022] As a further improvement of this technical solution, a vibrator is fixedly arranged on one side of the screening box, and the center of gravity of the vibrator coincides with the axis of the blanking channel.
[0023] The beneficial effect of adopting the above further solution is that by the operation of the vibrator to generate vibration, and then driving the screening box, the slide plate and the screening plates to vibrate, the silicon carbide particles falling on the screening plates are screened and stratified.
[0024] As a further improvement of this technical solution, a slot is opened on the other side of the screening box, and a baffle is slidably arranged in the slot, and the baffle is used to block silicon carbide particles of different particle sizes.
[0025] The beneficial effect of adopting the above further solution is that by pulling the baffle, the silicon carbide particles of different layers can be successively separated from the top of the corresponding screening plate, so that the silicon carbide particles of different particle sizes fall into the corresponding external containers, and the silicon carbide particles of different particle sizes can be respectively taken out for subsequent production of silicon carbide.
[0026] The second purpose is to provide a preparation process for high-energy composite functional structural materials, including the following steps:
[0027] S1: According to the particle size requirements of the silicon carbide particles, adjust the number of arc-shaped strips and crushing teeth on the roller body, regularly take out a certain number of arc-shaped strips and crushing teeth from different annular grooves, or reinstall and fix a certain number of arc-shaped strips and crushing teeth in the idle annular grooves through the first bolt and the second bolt;
[0028] S2: Crush the silicon carbide block. Drive the arc-shaped bar and the crushing teeth to rotate rapidly through the driving device to crush the silicon carbide block;
[0029] S3: Screen the crushed silicon carbide particles. Generate vibration through the operation of the vibrating machine to drive the screening box and the screening plate to vibrate, so that silicon carbide particles of different particle sizes pass through each screening plate respectively, and silicon carbide particles of a specific particle size continuously roll downward along the surface of the corresponding screening plate;
[0030] S4: Take out the silicon carbide particles of different particle sizes. By pulling the baffle plate, the silicon carbide particles in different layers can leave the top of the corresponding screening plate successively.
[0031] In addition to the purposes, features and advantages described above, the present invention has other purposes, features and advantages. The following will refer to the drawings to make a further detailed description of the present invention. Description of the Drawings

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

[0044] When wanting to repair the crushing unit, one can choose to weld a new crushing unit onto the crushing mechanism, but the original crushing strength of the crushing unit cannot be restored, resulting in a reduction in crushing efficiency. One can also choose to replace the entire crushing mechanism, but the economic cost is very high; if one wants to adjust the particle size of the crushed silicon carbide and screen out suitable particle sizes, increasing the rotation speed of the crushing mechanism will consume more energy, and repeatedly and cyclically crushing the silicon carbide block will significantly increase the crushing time of the silicon carbide.
[0045] Embodiment 1
[0046] One of the purposes of the present invention is to provide a preparation device for high-energy composite functional structural materials. Please refer to Figures 1-9 , which includes a frame 1. At one end of the top of the frame 1, two symmetrically distributed driving devices 2 for generating axial force are fixedly arranged. The driving device 2 includes a driving motor, a pulley and a belt. The driving motor rotates, driving the pulley and the belt to rotate, generating a driving force. At the other end of the top of the frame 1, an equipment box 3 is fixedly arranged. At the bottom of the equipment box 3, a feeding channel 4 is fixedly communicated. Inside the equipment box 3, two crushing mechanisms 5 for crushing silicon carbide blocks are symmetrically and rotatably arranged. The two crushing mechanisms 5 are respectively connected to the output ends of the two driving devices 2, and the crushing mechanism 5 is designed in a modular manner, forming multiple crushing units, which can be disassembled, replaced point by point or in strips, and the particle size of the silicon carbide can be adjusted. At the bottom of the feeding channel 4, a screening mechanism 6 for screening silicon carbide particles is arranged. The screening mechanism 6 generates a vibration force and shakes, continuing to crush the silicon carbide particles, screening and stratifying the silicon carbide particles to distinguish silicon carbide with different particle sizes, wherein:
[0047] The present invention is as Figures 1-3As shown, considering that the crushing mechanism 5 is generally an integral whole, during long-term use, the crushing units on the crushing mechanism 5 will inevitably experience wear or breakage. After wear or breakage, the crushing units cannot effectively crush the silicon carbide blocks. Since the crushing mechanism 5 is an inseparable whole, when wanting to repair the crushing units, one can choose to weld new crushing units onto the crushing mechanism 5. However, the original crushing strength of the crushing units cannot be restored, resulting in a decrease in crushing efficiency. One can also choose to replace the entire crushing mechanism 5, but the economic cost is very high and it is not very practical. Therefore, as Figures 1-3 shown, two driving devices 2 drive two crushing mechanisms 5 to rotate. The crushing mechanisms 5 generate axial forces to drive the crushing units to rotate. The crushing units rotate at high speed to crush the silicon carbide blocks. If a crushing unit is damaged, the damaged crushing unit can be replaced point by point or strip by strip. The new crushing unit has full crushing strength, improving the crushing efficiency. Moreover, there is no need to replace the entire crushing mechanism 5, only some crushing units need to be replaced, which is conducive to significantly reducing the economic cost and has strong practicability;
[0048] Also, the number of crushing units on the existing crushing mechanism 5 is fixed. If one wants to adjust the particle size of the crushed silicon carbide and screen out appropriate particle sizes, generally, by increasing the rotation speed of the crushing mechanism 5 or repeatedly and cyclically crushing the silicon carbide blocks, the above purpose can be achieved. However, increasing the rotation speed of the crushing mechanism 5 will consume more energy, and repeatedly and cyclically crushing the silicon carbide blocks will significantly increase the crushing time of the silicon carbide, and the crushing efficiency is low. Therefore, as Figure 4 and Figure 7 shown, by regularly reducing or increasing the number of crushing units on the crushing mechanism 5, the number of crushing units on the surface of the crushing mechanism 5 can be changed. In this way, the number of times the crushing units crush the silicon carbide blocks can be reduced or increased, so as to achieve the purpose of adjusting the particle size of the silicon carbide particles. There is no need to increase the rotation speed of the crushing mechanism 5 to save energy, nor is it necessary to repeatedly and cyclically crush the silicon carbide blocks to reduce the crushing time of the silicon carbide, which is conducive to improving the crushing efficiency. And in cooperation with the screening mechanism 6 to generate vibration, not only can the silicon carbide blocks that are hit by the crushing mechanism 5 and have cracks but are not broken be further crushed to further improve the crushing effect, but also the silicon carbide particles can be stratified to screen out silicon carbide particles of different particle sizes.
[0049] On the above basis, the specific structure is disclosed in detail:
[0050] To achieve the driving device 2 generating an axial force to drive the crushing mechanism 5 to rotate to crush the silicon carbide blocks entering the equipment box 3, the specific structure of the crushing mechanism 5 needs to be disclosed. Therefore, as Figure 4As shown in the figure, the crushing mechanism 5 includes a roller body 51. The roller body 51 is rotatably arranged in the equipment box 3, and one end of the roller body 51 is fixedly connected to the output end of the driving device 2. A plurality of uniformly distributed annular grooves 52 are formed on the surface of the roller body 51, and the crushing units are arranged in the annular grooves 52.
[0051] The axis of the annular groove 52 coincides with the axis of the roller body 51. After the crushing units are installed in the annular grooves 52, the distances of the crushing units from the axis of the annular groove 52 are the same, so that the hitting effects of different crushing units on the silicon carbide blocks are the same.
[0052] By generating an axial force through the driving device 2, the roller body 51 can be driven to rotate at a high speed, and then the crushing units on the roller body 51 can be driven to rotate, so as to crush the silicon carbide blocks. When a crushing unit is damaged, the damaged crushing unit can be removed and a new crushing unit can be replaced, without replacing the entire roller body 51, which reduces the economic cost. And if it is necessary to adjust the particle size of the silicon carbide particles, the crushing units can be regularly removed from the annular grooves 52, so as to reduce or increase the contact times between the crushing units and the silicon carbide, thereby achieving the purpose of adjusting the particle size of the silicon carbide particles.
[0053] Among them, in order to replace a new crushing unit after the old crushing unit is damaged and regularly adjust the number of crushing units, the specific structure of the crushing mechanism 5 needs to be further disclosed. Therefore, as Figure 4 shown in the figure, the crushing unit includes two arc-shaped strips 53. The two arc-shaped strips 53 are both fixedly arranged in the same annular groove 52 through a plurality of first bolts. A plurality of arc-shaped distributed mounting grooves are formed on the outer wall of the arc-shaped strip 53, and crushing teeth 54 for crushing the silicon carbide blocks are fixedly arranged in the mounting grooves through second bolts.
[0054] The axis of the arc-shaped strip 53 coincides with the axis of the annular groove 52, so that the positions of different arc-shaped strips 53 from the axis of the roller body 51 are the same, and the crushing effects of different arc-shaped strips 53 and crushing teeth 54 on the silicon carbide blocks are basically the same.
[0055] By loosening or tightening the first bolt to disassemble and assemble the arc-shaped strip 53, and loosening or tightening the second bolt to disassemble and assemble the crushing teeth 54, when the crushing teeth 54 are worn or broken due to long-term hitting of the silicon carbide block, a new arc-shaped strip 53 or crushing teeth 54 can be replaced to restore the initial crushing strength of the crushing teeth 54, without replacing the entire roller body 51. And if it is necessary to adjust the particle size of the crushed silicon carbide block, a certain number of arc-shaped strips 53 and crushing teeth 54 can be regularly taken out from different annular grooves 52, or a certain number of arc-shaped strips 53 and crushing teeth 54 can be reinstalled and fixed in the idle annular grooves 52 through the first bolt and the second bolt to reduce or increase the number of arc-shaped strips 53 and crushing teeth 54, so as to adjust the particle size of the crushed silicon carbide block. The more the arc-shaped strips 53 and crushing teeth 54 are regularly arranged on the roller body 51, the smaller the particles of the silicon carbide block can be hit to obtain smaller particle sizes, and vice versa, larger particle-sized silicon carbide particles can be obtained.
[0056] To enable the screening mechanism 6 to generate vibration and continue to crush the silicon carbide block with cracks but not yet cracked, it is necessary to disclose the specific structure of the screening mechanism 6. Therefore, as Figure 7 shown, the screening mechanism 6 includes two fixing plates 61. One ends of the two fixing plates 61 are respectively fixedly arranged on both sides of the feeding channel 4. The tops of the fixing plates 61 are both movably provided with sliding plates 62 through a plurality of elastic members. The elastic members include springs and guide rods. The springs are sleeved on the guide rods, and the sliding plates 62 slide on the guide rods. One ends of the two sliding plates 62 are fixedly provided with the same screening box 63. By generating driving force by the screening mechanism 6 itself to drive the screening box 63 and the sliding plates 62 to vibrate, the silicon carbide block falling from the feeding channel 4 into the screening box 63 can be driven to vibrate, so that the silicon carbide block with cracks but not yet cracked continues to be crushed, enhancing the crushing effect, and preparing to screen silicon carbide particles of different particle sizes and stratify them.
[0057] To make the screening box 63 vibrate and drive the silicon carbide particles entering the screening box 63 to vibrate to achieve the stratification effect, it is necessary to continue to disclose the specific structure of the screening mechanism 6. Therefore, as Figure 9 shown, a plurality of inclined screening plates 64 are fixedly arranged inside the screening box 63, and the plurality of screening plates 64 are uniformly arranged from top to bottom;
[0058] The pore diameters on the plurality of screening plates 64 decrease successively from top to bottom;
[0059] By driving the plurality of screening plates 64 to vibrate through the vibration of the screening box 63, silicon carbide particles of different particle sizes respectively pass through each screening plate 64, and silicon carbide particles of a specific particle size continuously roll downward along the surface of the corresponding screening plate 64, achieving the purpose of screening silicon carbide particles of different particle sizes and stratifying them.
[0060] Among them, to make the screening box 63 and multiple screening plates 64 vibrate to drive the silicon carbide particles to vibrate, it is necessary to further disclose the specific structure of the screening mechanism 6. Therefore, as Figure 3 shown, a vibrator 65 is fixedly arranged on one side of the screening box 63, and the center of gravity of the vibrator 65 coincides with the axis of the feeding channel 4. By the operation of the vibrator 65 to generate vibration, the screening box 63, the sliding plate 62 and the screening plates 64 are driven to vibrate, so as to screen and stratify the silicon carbide particles falling on the screening plates 64.
[0061] Among them, after the silicon carbide particles of different particle sizes are stratified, they need to be taken out separately for subsequent production of silicon carbide. It is necessary to further expand the specific structure of the screening mechanism 6. Therefore, as Figure 7 shown, a slot is opened on the other side of the screening box 63, and a baffle 66 is slidably arranged in the slot. The baffle 66 is used to block the silicon carbide particles of different particle sizes. By pulling the baffle 66, the silicon carbide particles of different layers can leave the top of the corresponding screening plate 64 successively, so that the silicon carbide particles of different particle sizes fall into the corresponding external containers, and the silicon carbide particles of different particle sizes can be taken out separately for subsequent production of silicon carbide.
[0062] The second object of the present invention is to provide a preparation process of a high-energy composite functional structural material, including the following steps:
[0063] S1: According to the particle size requirements of the silicon carbide particles, adjust the number of the arc-shaped strips 53 and the crushing teeth 54 on the roller body 51, regularly take out a certain number of arc-shaped strips 53 and crushing teeth 54 from different annular grooves 52, or reinstall and fix a certain number of arc-shaped strips 53 and crushing teeth 54 in the idle annular grooves 52 through the first bolt and the second bolt;
[0064] S2: Crush the silicon carbide block. Drive the arc-shaped strips 53 and the crushing teeth 54 to rotate rapidly through the driving device 2 to crush the silicon carbide block;
[0065] S3: Screen the crushed silicon carbide particles. By the operation of the vibrator 65 to generate vibration, drive the screening box 63 and the screening plates 64 to vibrate, so that the silicon carbide particles of different particle sizes respectively pass through each screening plate 64, and the silicon carbide particles of a specific particle size continuously roll downward along the surface of the corresponding screening plate 64;
[0066] S4: Take out the silicon carbide particles of different particle sizes. By pulling the baffle 66, the silicon carbide particles of different layers can leave the top of the corresponding screening plate 64 successively.
[0067] In summary, the overall working principle of the present invention is as follows:
[0068] When it is necessary to use this silicon carbide crusher to crush silicon carbide blocks, first, according to the particle size requirements of silicon carbide particles, adjust the number of arc-shaped bars 53 and crushing teeth 54 on the roller body 51. Disassemble and assemble the arc-shaped bars 53 by loosening or tightening the first bolts, and disassemble and assemble the crushing teeth 54 by loosening or tightening the second bolts. Regularly take out a certain number of arc-shaped bars 53 and crushing teeth 54 from different annular grooves 52, or reinstall and fix a certain number of arc-shaped bars 53 and crushing teeth 54 in the idle annular grooves 52 through the first bolts and the second bolts to reduce or increase the number of arc-shaped bars 53 and crushing teeth 54, so as to adjust the particle size of the silicon carbide blocks after being crushed.
[0069] Then start crushing the silicon carbide blocks. Put an appropriate amount of silicon carbide blocks into the equipment box 3 from the feeding end of the equipment box 3, start the driving device 2 to make it rotate. The driving device 2 generates an axial force, which can drive the roller body 51 to rotate at a high speed, and then drive the arc-shaped bars 53 and the crushing teeth 54 to rotate quickly to crush the silicon carbide blocks.
[0070] Then screen the crushed silicon carbide particles. The silicon carbide particles fall into the screening box 63 through the feeding channel 4. The vibrator 65 operates to generate vibration, which then drives the screening box 63, the slide plate 62 and the screening plate 64 to vibrate, so that silicon carbide particles of different particle sizes respectively pass through each screening plate 64. The silicon carbide particles with a specific particle size continuously roll down along the surface of the corresponding screening plate 64, achieving the purpose of screening silicon carbide particles of different particle sizes and making them stratified.
[0071] Then take out the silicon carbide particles of different particle sizes respectively. Pull the baffle 66, and the silicon carbide particles of different layers can leave the top of the corresponding screening plate 64 successively, so that the silicon carbide particles of different particle sizes fall into the corresponding external containers, and the silicon carbide particles of different particle sizes can be taken out respectively for subsequent production of silicon carbide.
