Description
Technical Field
[0001] This invention relates to the field of silicon carbide raw material crushing technology, specifically to a raw material crushing device for silicon carbide production. Background Technology
[0002] Silicon carbide, as a multifunctional material, has applications in various fields such as industry, electronics, and energy. In the actual production of silicon carbide, petroleum coke is used to provide carbon. It needs to be crushed first to facilitate subsequent processing. However, the current raw material crushing equipment used in silicon carbide production is prone to jamming if the crushing roller is not pre-started when feeding petroleum coke. In this case, it is not convenient for the crushing roller to use inertial energy for crushing, and it may even cause the motor to fail to start normally or cause damage. It is also not convenient to automatically limit the pre-start of the motor. At the same time, it is not convenient to automatically discharge the uncrushed petroleum coke after crushing, which will further affect the start of the subsequent motor. In addition, it is not convenient to use the crushed powder to help guide the workers to check the complete heating of the petroleum coke. The surface temperature of the crushing roller is high when crushing for a long time, which can easily cause coking to adhere to the crushing roller.

[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] This invention uses a rotating detection component to achieve automatic control during petroleum coke crushing. It is necessary to start two first motors first to drive the two crushing rollers into the crushing state before the feeding control component can carry out the discharge crushing work normally. Otherwise, the two rotating baffles will be in a closed state, and it is necessary to ensure that the crushing roller speed reaches the standard. This is to prevent the teeth on the crushing rollers from getting stuck if petroleum coke is added to the crushing rollers first in a stationary state. At this time, it is difficult to start the first motor and it is easy to increase the failure rate.
[0017] By using a switch control unit in conjunction with a power-off control unit, the start and stop of the two first motors can be controlled. This allows the operator to control the two crushing rollers to separate and maintain the maximum distance after the crushing work is completed before the power to the crushing rollers can be cut off. This also ensures that if there is any uncrushed petroleum coke between the two crushing rollers when they stop rotating, it can be discharged directly, preventing the uncrushed petroleum coke remaining between the two crushing rollers from causing further jamming.
[0018] The heating indicator can be used to heat the crushed petroleum coke particles, which can be used to test the sufficiency of the initial calcination of the petroleum coke. It can also provide a more intuitive prompt to the staff by taking advantage of the characteristic that incomplete combustion of petroleum coke will cause coking and adhesion when it is reheated.

[0031] 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.
[0032] Example 1: Please refer to Figures 1 to 11 As shown:
[0033] This invention provides a technical solution: a raw material crushing device for silicon carbide production, comprising a crushing mounting component 1, a rotation detection component 2 mounted on the crushing mounting component 1 for detecting the start-up of the crushing mounting component 1; a feeding control component 3 mounted on the crushing mounting component 1 for ensuring that material is fed only after the crushing mounting component 1 has started; a power-off control component 4 mounted on the crushing mounting component 1; a switch control component 5 mounted on the back of the crushing mounting component 1 for controlling anti-material accumulation; and a heating indicator component mounted on the crushing mounting component 1. 6; Heating indicator 6 is used to indicate the presence of petroleum coke; Crushing mounting component 1 includes: crushing mounting shell 101 and crushing roller 102, the bottom side of the crushing mounting shell 101 is provided with an opening; there are two crushing rollers 102, the front crushing roller 102 is rotatably mounted on the crushing mounting shell 101; the rear crushing roller 102 is located inside the crushing mounting shell 101; two first motors 103 control the two crushing rollers 102 to rotate in opposite directions to crush the petroleum coke; the two crushing rollers 102 are respectively provided with teeth; the two first motors 103 control the start and stop simultaneously.
[0034] The crushing mounting component 1 further includes: a first motor 103, of which two are provided. The front first motor 103 is fixedly mounted on the crushing mounting shell 101, and the output shaft of the front first motor 103 is fixedly mounted on the shaft end of the front crushing roller 102; the rear first motor 103 is located on the side of the crushing mounting shell 101. The rotation detection component 2 includes: a detection cover 201, a contact coil 202, a rotating arm 203, a counterweight rod 204, and a return spring 205. The detection cover 201 and the front crushing roller 102 are concentric. The detection cover 201 is fixedly mounted on the side of the crushing mounting shell 101. Inside the detection cover 201... Two electrical contact coils 202 are fixedly installed on the side, and the two electrical contact coils 202 are insulated from each other; a rotary arm 203 is fixedly installed on the shaft end of the front crushing roller 102; a counterweight rod 204 is slidably inserted on the rotary arm 203; a counterweight block is provided at the top of the counterweight rod 204; the bottom of the counterweight rod 204 is a conductor; the bottom of the counterweight rod 204 is attached to the two electrical contact coils 202; one end of the return spring 205 is fixedly installed on the counterweight rod 204; the other end of the return spring 205 is fixedly installed on the rotary arm 203; the feeding control component 3 includes: a feeding mounting shell 301, a discharge baffle 3011, a rotating baffle 302, and a baffle shaft 3021, and the feeding mounting... The housing 301 is bolted to the crushing mounting housing 101; two discharge baffles 3011 are fixedly installed inside the feeding mounting housing 301, and the two discharge baffles 3011 are respectively located above the two crushing rollers 102; two baffle shafts 3021 are rotatably installed on the feeding mounting housing 301, and the two ends of the two baffle shafts 3021 respectively pass through the feeding mounting housing 301; rotating baffles 302 are fixedly installed on the two baffle shafts 3021 respectively; torsion springs are sleeved at both ends of the two baffle shafts 3021, and the torsion springs at both ends of the two baffle shafts 3021 are respectively connected to the ends of the two baffle shafts 3021 and the feeding mounting housing 101. Between 1; the two rotating baffles 302 are inclined; the distance between the swinging opening of the two rotating baffles 302 is less than the maximum distance between the two crushing rollers 102; the feeding control component 3 also includes: an upper electromagnet 303, a lower electromagnet 304 and a limiting plate 305, two rows of upper electromagnets 303 are fixedly installed on the feeding mounting shell 301; a row of lower electromagnets 304 are fixedly installed on each of the two rotating baffles 302; the two rows of upper electromagnets 303 are magnetically attached to the two rows of lower electromagnets 304 respectively; two limiting plates 305 are fixedly installed on the inner side of the feeding mounting shell 301; the two limiting plates 305 are respectively aligned with the two rotating baffles 302;Two connecting coils 202 are connected in series with two rows of upper electromagnets 303 and lower electromagnets 304 respectively. Two rotating baffles 302, in conjunction with a limiting plate 305, can limit the feed volume, ensuring particle size control during the initial coarse crushing of petroleum coke and preventing excessive feed volume from affecting the crushing quality of the crushing rollers 102. Simultaneously, the two rotating baffles 302, in conjunction with the torsion springs on the baffle shafts 3021, can automatically close after feeding, improving the dust and splash prevention effect. The rotating detection element 2 enables automatic control. During petroleum coke crushing, the two first motors 103 must be started first, driving the two crushing rollers 102 into a crushing state before the feed control element 3 can properly perform the discharge crushing operation. Otherwise, the two rotating baffles 302 will be in a closed state, and the rotation speed of the crushing rollers 102 must be ensured to meet the standard. Adding petroleum coke to the crushing rollers 102 while they are stationary can cause the teeth on the crushing rollers 102 to become stuck, making it difficult to start the first motors 103 and increasing the risk of spillage. Direct feeding and starting can easily increase the failure rate. Directly feeding and starting the machine can cause the motor to be subjected to a heavy load current, potentially burning out the windings or triggering a protection shutdown. This structure ensures the quality of operation. Furthermore, when petroleum coke is fed in after the crushing roller 102 maintains a high rotation speed, the crushing of petroleum coke is smoother due to the inertial kinetic energy of the crushing roller 102 itself, reducing the risk of material jamming. The structure is simple and convenient to operate. Controlling the rotation of the two first motors 103 involves energizing them. As the speed of the front crushing roller 102 gradually increases, once the speed reaches the target, the front crushing roller 102 drives the rotating arm 203 to rotate. Under the counterweight of the top counterweight block, centrifugal force controls the counterweight rod 204 to move towards the counterweight block on the counterweight rod 204, compressing the return spring 205. At this point, the counterweight rod 204 is no longer attached to the two contact coils 202, preventing normal conduction. The upper electromagnet 303 and lower electromagnet 304 are no longer magnetically attracted to each other, allowing petroleum coke to be fed normally onto the two rotating baffles 302.
[0035] The power-off control component 4 includes: a power-off control frame 401 and a hydraulic cylinder 402. The power-off control frame 401 is slidably inserted into the crushing mounting shell 101. A rear crushing roller 102 is rotatably mounted on the power-off control frame 401. A rear first motor 103 is fixedly mounted on the power-off control frame 401. The output shaft of the rear first motor 103 is fixedly mounted on the shaft end of the rear crushing roller 102. Two hydraulic cylinders 402 are fixedly mounted on the power-off control frame 401, and the output shafts of the two hydraulic cylinders 402 pass through the power-off control frame 401 respectively. The output shafts of the two hydraulic cylinders 402 are fixedly mounted on the back of the crushing mounting shell 101 respectively. The power-off control component 4 also includes: a power-on control block 403. A power connection control block 403 is fixedly installed on the frame 401; the switch control component 5 includes a switch mounting bracket 501 and a distance switch 502. The switch mounting bracket 501 is fixedly installed on the crushing mounting shell 101 by bolts; two distance switches 502 are fixedly installed on the switch mounting bracket 501; the two distance switches 502 are aligned with the power connection control block 403; after the power-off control bracket 401 drives the two crushing rollers 102 away, the two distance switches 502 respectively control the two first motors 103 to disconnect from the power; the two distance switches 502 are electrically connected to the two first motors 103 respectively. By using the switch control component 5 in conjunction with the power-off control component 4, the start and stop of the two first motors 103 can be controlled, and the limiting operation can be achieved. After completing the crushing operation, the operator must first separate the two crushing rollers 102 to maintain the maximum distance before de-energizing them. This ensures that any uncrushed petroleum coke remaining between the two rollers 102 when they stop can be directly discharged, preventing further jamming when the rollers are restarted. The more rational structure further enhances the anti-jamming effect, allowing for seamless operation and extending the lifespan of the first motor 103. The adjustable spacing of the crushing rollers 102 also facilitates operation during operation. When problems such as jamming occur, the two crushing rollers 102 are separated to directly discharge the raw material. When crushing is required, the two crushing rollers 102 will slowly approach each other. At this time, even if there is some residual material, it can be discharged as the two crushing rollers 102 rotate. Similarly, when it is necessary to stop the crushing operation, the hydraulic cylinder 402 is controlled to drive the pullback of the power-off control frame 401 until the two crushing rollers 102 are separated to the maximum distance. At this time, the power-on control block 403 is also driven to squeeze the two separation switches 502, thereby controlling the two first motors 103 to cut off the power and stop the machine. At this time, if there is still petroleum coke between the two crushing rollers 102 that has not been crushed, it can be discharged directly between the two crushing rollers 102.
[0036] In Embodiment 2, based on Embodiment 1, the heating indicator 6 includes: a discharge inclined panel 601 and an electric heating plate 6011. The discharge inclined panel 601 is fixedly installed inside the crushing mounting shell 101; the electric heating plate 6011 is embedded in the discharge inclined panel 601. The heating indicator 6 also includes: a second motor 602 and a swing rod 603. The second motor 602 is fixedly installed at the bottom of the discharge inclined panel 601, and the output shaft of the second motor 602 passes through the discharge inclined panel 601; the swing rod 603 is fixedly installed on the output shaft of the second motor 602; the bottom of the swing rod 603 has an inclined structure; the swing rod 603 is aligned with the electric heating plate 6011 and uses heating... The indicator 6 can use the swing rod 603 to move the crushed petroleum coke, promoting its discharge from the discharge inclined panel 601 and preventing blockage. At the same time, it can work with the electric heating plate 6011 to provide auxiliary heating. The crushed petroleum coke particles can be heated to test the sufficiency of the initial calcination of the petroleum coke. Taking advantage of the characteristic that incomplete combustion of petroleum coke will cause coking and adhesion when reheated, it provides a more intuitive reminder to the staff that if the petroleum coke is not fully calcined, the high temperature generated by the rotation and friction of the crushing roller 102 will cause the petroleum coke to coke and adhere to the crushing roller 102. At the same time, the swing rod 603 can also be used to easily scrape and clean the electric heating plate 6011.
[0037] The working principle of this embodiment is as follows: First, when the equipment is not crushing, with the compression of the return spring 205, the bottom of the rotating arm 203 is attached to the two contact coils 202. At this time, the upper electromagnet 303 and the lower electromagnet 304 are energized and magnetically attracted to each other, causing the two rotating baffles 302 to rotate upwards, thus achieving a closed state for the two rotating baffles 302. When crushing is required, the hydraulic cylinder 402 is controlled to push the power-off control frame 401 forward, driving the rear crushing roller 102 and the rear first motor 103 forward, closer to the front crushing roller 102. When the power control block 403 stops pressing against the two interlocking switches 502, it controls the two first motors 103 to start and drive the two crushing rollers 102 to rotate and crush. When the two first motors 103 are energized and rotating, the speed of the front crushing roller 102 gradually increases. After the speed reaches the target, the centrifugal force gradually increases. The front crushing roller 102 drives the rotary arm 203 to rotate. Under the counterweight of the top counterweight block, the centrifugal force controls the counterweight rod 204 to move towards the counterweight block on the counterweight rod 204, compressing the return spring 205. At this time, the counterweight rod... 204 is no longer attached to the two contact coils 202. At this time, the two contact coils 202 cannot conduct normally, and the upper electromagnet 303 and the lower electromagnet 304 no longer attract each other magnetically. At this time, petroleum coke can be normally put on the two rotating baffles 302. Under the action of the weight of the petroleum coke, it will press down on the two rotating baffles 302 to form an opening, so that the material can be crushed by the two crushing rollers 102. As the petroleum coke on the two rotating baffles 302 falls onto the two crushing rollers 102, the torsion spring on the baffle shaft 3021 controls the two rotating baffles 302 to flip up and reset to block. The structure is more reasonable and ensures that the two crushing rollers 102 are activated first during crushing. When it is necessary to stop the crushing operation, the hydraulic cylinder 402 is controlled to drive the power-off control frame 401 back until the two crushing rollers 102 are separated to the maximum distance. At this time, the power-on control block 403 is also driven to squeeze the two separation switches 502, thereby controlling the two first motors 103 to be powered off and stopped. If there is still petroleum coke between the two crushing rollers 102 that has not been crushed, it can be discharged directly between the two crushing rollers 102. The head and tail materials can then be crushed again.
[0038] As the crushing roller 102 crushes and discharges petroleum coke, it is guided by the inclined discharge panel 601 and discharged from the opening on the bottom side of the crushing mounting shell 101. The second motor 602 can be controlled to drive the swing rod 603 to rotate, promoting material discharge. At the same time, the swing rod 603 can scrape and clean the surface of the electric heating plate 6011. The operator can periodically control the electric heating plate 6011 to be energized and the second motor 602 to be paused. When the petroleum coke on the surface of the electric heating plate 6011 is not properly calcined, coke will be produced and adhered to the electric heating plate 6011. The operator can directly observe the coke adhesion on the surface of the electric heating plate 6011 to determine whether this batch of petroleum coke will adhere to the crushing roller 102. The structure is more reasonable.
