Abstract
Description
Technical Field
[0001] This utility model relates to the field of silicon carbide production, specifically a cross-flow silicon carbide particle impurity sorting device. Background Technology
[0002] Silicon carbide is an inorganic substance that is produced by high-temperature smelting of raw materials such as quartz sand, petroleum coke or coal coke, and wood chips in an electric resistance furnace. Silicon carbide has four main application areas: functional ceramics, advanced refractory materials, abrasives, and metallurgical raw materials.
[0003] After silicon carbide production, there will be many large silicon carbide particles and impurities. These impurities cannot be used together with silicon carbide, so silicon carbide particle impurity sorting equipment is needed for screening. Silicon carbide particles that meet the size requirements are collected and used, while larger silicon carbide particles that do not meet the specifications need to be sorted out. Silicon carbide screening is usually done using silicon carbide particle impurity sorting equipment.
[0004] Currently, when silicon carbide particle impurity sorting equipment screens silicon carbide particles, those that meet the screening conditions will pass through the screening equipment. However, those that do not meet the conditions will gradually accumulate on the screen in the screening device. As the accumulated silicon carbide particle impurities increase, the silicon carbide particles that meet the screening conditions will be blocked by the silicon carbide particles that do not meet the conditions, thus making it impossible for the collection and screening device to perform screening work. Utility Model Content
[0005] To address the shortcomings of existing technologies, current silicon carbide particle impurity sorting equipment, when screening silicon carbide particles, allows those that meet the screening conditions to pass through the equipment, while those that do not meet the conditions gradually accumulate on the screen. As the accumulated silicon carbide particles increase, those that meet the screening conditions are obstructed by those that do not, thus preventing the collection and screening device from performing its screening work. This invention proposes a cross-flow silicon carbide particle impurity sorting equipment.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The cross-flow silicon carbide particle impurity sorting device of this utility model includes a screening device, a conveyor belt is provided on one side of the screening device, a flow trough is opened at the top of the screening device, a debris port is provided at one end of the flow trough, the debris port is opened at the end of the screening device away from the conveyor belt, a screening trough is opened at the bottom of the screening device, an inclined plate is fixedly connected to the bottom of the screening trough, a screening port is opened at the front of the screening trough, multiple sets of screen holes are opened at the top of the debris port, and a vibration mechanism is provided on one side of the screening device.
[0007] Preferably, the vibration mechanism includes a rotating disk, which is disposed on one side of the screening equipment. The screening equipment has an installation groove on the side near the rotating disk, and a motor is fixedly connected inside the installation groove. The output shaft of the motor is fixedly connected to the rotating disk. A rotating column is fixedly connected to one side of the rotating disk. A swing block is sleeved on the outside of the rotating column. A rotating rod is fixedly connected to the rear of the swing block. One end of the rotating rod is rotatably connected to the screening equipment. Multiple sets of toothed angles are formed at the bottom end of the swing block.
[0008] Preferably, the bottom end of the swing block is provided with a moving rod, the top end of the moving rod is provided with multiple sets of teeth, the top end of the moving rod meshes with the bottom end of the swing block, two sets of guide columns are sleeved on the outside of the moving rod, the guide columns are fixedly connected to the screening equipment, and impact blocks are fixedly connected to both ends of the moving rod.
[0009] Preferably, a stop post is provided at the top of the swing block, and the stop post is fixedly connected to the rotating column.
[0010] Preferably, a collection box is provided at the front of the screening port, and threaded holes are provided on both sides of the bottom front of the screening device, and connecting plates are fixedly connected to both ends of the collection box.
[0011] Preferably, the connecting plate has screws inside, and the screws pass through the connecting plate and are threadedly connected to the threaded hole.
[0012] The advantages of this utility model are:
[0013] This invention utilizes a vibrating mechanism to transport silicon carbide particles via a conveyor belt to a flow trough at the top of the screening equipment. A motor then drives a rotating disc and a rotating column to rotate. The rotation of the column causes a swing block to oscillate reciprocally around a rotating rod. The top of the moving rod engages with the bottom of the swing block, enabling the moving rod to move laterally. The impact blocks at both ends of the moving block strike the screening device, causing the silicon carbide particles to roll down the flow trough under gravity. After the vibration screening process, silicon carbide particles that meet the screening requirements can pass through the screen openings. Furthermore, large-volume silicon carbide particles that cannot pass through the sieve holes will not clog the flow channel. Instead, they will roll out from the debris outlet under the action of gravity and vibration. This solves the problem in current silicon carbide particle impurity sorting equipment where, during silicon carbide particle screening, silicon carbide particles that meet the screening conditions pass through the screening equipment, but silicon carbide particles that do not meet the conditions gradually accumulate on the screen in the screening device. As the accumulated silicon carbide particles increase, the silicon carbide particles that meet the screening conditions will be blocked by the silicon carbide particles that do not meet the conditions, thus preventing the collection and screening device from performing screening work.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] Please see Figure 1 - Figure 5As shown, a cross-flow silicon carbide particle impurity sorting device includes a screening device 1, a conveyor belt 2 on one side of the screening device 1, a flow trough 3 at the top of the screening device 1, a debris port 4 at one end of the flow trough 3, the debris port 4 being located at the end of the screening device 1 away from the conveyor belt 2, a screening trough 5 at the bottom of the screening device 1, an inclined plate 6 fixedly connected to the bottom of the screening trough 5, a screening port 7 at the front of the screening trough 5, multiple sets of screen holes 8 at the top of the debris port 4, and a vibration mechanism on one side of the screening device 1.
[0023] During operation, the vibration mechanism's structural design allows silicon carbide particles to be transported via conveyor belt 2 to the top flow channel 3 of the screening equipment 1. Then, motor 11 activates, driving rotating disk 9 and rotating column 12. The rotation of column 12 causes oscillating block 13 to reciprocate around rotating rod 100. This, in turn, causes the top of moving rod 15 to mesh with the bottom of oscillating block 13, enabling lateral reciprocating movement of rod 15. The impact blocks 17 at both ends of the moving block then impact the screening equipment 1, causing the silicon carbide particles to roll off the flow channel 3 under gravity. The vibrating screen then separates the silicon carbide particles that meet the screening requirements. Silicon carbide particles can pass through the sieve holes 8, and large-volume impurities that cannot pass through the sieve holes 8 will not clog the flow channel 3. They will roll out from the impurity port 4 under the action of gravity and vibration mechanism. This solves the problem that in current silicon carbide particle impurity sorting equipment, when silicon carbide particles that meet the screening conditions pass through the screening equipment 1, but silicon carbide particles that do not meet the conditions gradually accumulate on the screen in the screening device. As the accumulated silicon carbide particles increase, the silicon carbide particles that meet the screening conditions will be blocked by the silicon carbide particles that do not meet the conditions, thus making it impossible for the collection and screening device to perform screening work.
[0024] Furthermore, such as Figure 4 As shown, the vibration mechanism includes a rotating disk 9, which is disposed on one side of the screening equipment 1. The screening equipment 1 has an installation groove 10 on the side near the rotating disk 9, and a motor 11 is fixedly connected inside the installation groove 10. The output shaft of the motor 11 is fixedly connected to the rotating disk 9. A rotating column 12 is fixedly connected to one side of the rotating disk 9. A swing block 13 is sleeved on the outside of the rotating column 12. A rotating rod 100 is fixedly connected to the rear of the swing block 13. One end of the rotating rod 100 is rotatably connected to the screening equipment 1. Multiple sets of tooth angles 14 are opened at the bottom of the swing block 13.
[0025] During operation, the motor 11 is turned on to drive the rotating disk 9 and the rotating column 12 to rotate. The rotation of the rotating column 12 will drive the swing block 13 to swing back and forth around the rotating rod 100. Thus, the top end of the moving rod 15 engages with the bottom end of the swing block 13 to achieve the reciprocating lateral movement of the moving rod 15. In this way, the impact blocks 17 at both ends of the moving rod 15 can repeatedly impact the screening equipment 1.
[0026] Furthermore, such as Figure 4 As shown, a moving rod 15 is provided at the bottom of the swing block 13. Multiple sets of tooth angles 14 are provided at the top of the moving rod 15. The top of the moving rod 15 meshes with the bottom of the swing block 13. Two sets of guide columns 16 are sleeved on the outside of the moving rod 15. The guide columns 16 are fixedly connected to the screening equipment 1. Impact blocks 17 are fixedly connected to both ends of the moving rod 15.
[0027] During operation, the guide column 16 can restrict the position of the moving rod 15 so that it is always engaged with the swing block 13, and can also restrict the direction of movement of the moving rod 15 so that it can continuously impact the screening equipment 1.
[0028] Furthermore, such as Figure 4 and Figure 5 As shown, a stop post 18 is provided at the top of the swing block 13, and the stop post 18 is fixedly connected to the rotating column 12.
[0029] During operation, the diameter of the stop post 18 is larger than the diameter of the rotating post 12, so the stop post 18 can prevent the swing block 13 from disengaging from the rotating post 12.
[0030] Furthermore, such as Figure 2 As shown, a collection box 19 is provided at the front of the screening port 7, and threaded holes 20 are provided on both sides of the bottom front of the screening device 1. A connecting plate 21 is fixedly connected to both ends of the collection box 19.
[0031] During operation, silicon carbide particles that can pass through the sieve holes 8 fall from the flow tank 3 onto the inclined plate 6 of the screening tank 5, and enter the collection box 19 through the screening port 7.
[0032] Furthermore, such as Figure 2 As shown, a screw 22 is provided inside the connecting plate 21, and the screw 22 passes through the connecting plate 21 and is threadedly connected to the threaded hole 20.
[0033] When the inside of the collection box 19 is filled with silicon carbide particles during operation, the collection box 19 needs to be removed for centralized cleaning. The screw 22 can be removed from the threaded hole 20 and pulled out of the connecting plate 21. Then the collection box 19 can be removed for cleaning. After cleaning, the collection box 19 can be reinstalled.
[0034] Working principle: Silicon carbide particles are transported to the flow trough 3 at the top of the screening equipment 1 via conveyor belt 2. Then, the motor 11 drives the rotating disk 9 and rotating column 12 to rotate. The rotation of the rotating column 12 causes the swing block 13 to swing back and forth around the rotating rod 100. This causes the top of the moving rod 15 to mesh with the bottom of the swing block 13, thus enabling the moving rod 15 to move laterally back and forth. The impact blocks 17 at both ends of the moving block then strike the conveyor belt 2, causing the silicon carbide particles to roll off the flow trough 3. After the vibrating screen operation, the silicon carbide particles can be screened through the screen holes 8. Furthermore, silicon carbide particles that cannot pass through the sieve hole 8 will not clog the flow channel 3. They will roll out from the debris port 4 under the action of gravity and vibration mechanism, and then be collected by the staff at the debris port 4. Silicon carbide particles that can pass through the sieve hole 8 will fall from the flow channel 3 onto the inclined plate 6 of the screening channel 5 and enter the collection box 19 through the screening port 7. When the collection box 19 is full of silicon carbide particles, it is necessary to remove the collection box 19 for centralized cleaning. The screw 22 can be removed from the threaded hole 20 and pulled out of the connecting plate 21. Then the collection box 19 can be removed for cleaning. After cleaning, the collection box 19 can be reinstalled.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
