It is an ideal abrasive and is widely used in the abrasive industry. It is mainly used in the production of grinding wheels, cutting discs, etc.

[0003] Chinese patent CN117206006B discloses a silicon carbide crusher, which discharges unqualified crushed materials through a flap assembly, and then feeds them through a screw feeder to feed the unqualified materials into a feed hopper, thereby realizing secondary feeding and improving the material crushing quality. The material screening mechanism realizes multi-stage screening of the material, thereby improving the material processing efficiency after crushing, and can obtain materials of various sizes, thereby improving the screening efficiency.

[0015] To achieve the above object, the present invention provides the following technical solution: an energy-saving crushing method for producing silicon carbide granular sand, comprising the following steps: First, the silicon carbide is transported to the feed inlet by utilizing the conveying device and enters into the outer shell of the crusher. The silicon carbide is crushed by rotating the crushing rollers 1 and 2 in the outer shell of the crusher. The crushed silicon carbide granular sand will fall into the storage box for storage. The driving component drives the swing component to lift and lower back and forth along the lifting chute, so that the storage box containing the silicon carbide granular sand is flipped back and forth. While the swing component lifts and slides, the coordination component drives the limit slider to slide back and forth in the limit chute as the storage box is lifted and lowered, so that the sliding plate drives the breaking up slide column to slide to break up the silicon carbide granular sand in the storage box, and then the swing component drives the silicon carbide granular sand in the storage box to be flipped, so that the silicon carbide granular sand at the bottom layer can be flipped to the upper layer, and the iron impurities doped in the silicon carbide granular sand can be adsorbed by the magnetic absorption and collection device.

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The driving component drives the swing component to move up and down along the lifting chute, so that the storage box containing silicon carbide granular sand can be flipped back and forth. The uniform swing can effectively prevent the aggregation of silicon carbide granular sand and avoid the adhesion or accumulation between particles, thereby ensuring that the sand particles can flow more freely in the storage box and improving its working performance. While the swing component is lifting and sliding, the coordination component will drive the limit slider to slide back and forth in the limit chute as the storage box is lifted and lowered, so that the sliding plate drives the breaking slide column to slide to break up the silicon carbide granular sand in the storage box. The breaking slide column can break up the agglomerated silicon carbide granular sand and maintain the free flow of the sand particles, thereby improving the operability and transmission efficiency of the material.

[0017] 2. Through the intermittent rotation of the driving cam, when the lifting slider slides along the surface of the driving cam to the drop, the driving cam loses its limit on the lifting slider, and the compressed reset spring will quickly push the lifting slider to slide down along the lifting slide groove and collide. Through vibration and collision, larger particles and smaller particles can collide with each other, helping to distribute the particles more evenly and reduce the compaction caused by long-term storage, ensuring that the silicon carbide particles can flow out smoothly during use. As the lifting plate rack rises and falls, the storage box is driven to flip back and forth in two directions, so that different layers of silicon carbide sand can be fully mixed with each other.

[0018] 3. By driving the lifting plate rack up and down, the guide plates on both sides are driven to slide along the limit plate, and the sliding plate slides back and forth in the storage box, and at the same time drives the magnetic absorption collection device to adsorb the iron impurities in the silicon carbide granular sand, reducing the need for subsequent cleaning and maintenance work, and improving production efficiency and quality. According to the inclination of the storage box, the inclined coordination cloth can be adjusted to collect the silicon carbide granular sand that falls to the side into the storage box again, and the fallen silicon carbide granular sand can be recovered and collected into the storage box, which can minimize material waste, avoid resource loss, and thus improve economic benefits.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0023] The present invention will be further described below in conjunction with the embodiments.

[0024] Example 1 Reference Figure 1-Figure 5 , Figure 7 , Figure 8, which is the first embodiment of the present invention, provides a pulverizing device, including a pulverizer outer shell 100, a tumbling stirring mechanism 200 is installed in the pulverizer outer shell 100, the tumbling stirring mechanism 200 includes a feed inlet 201 opened at the top of the pulverizer outer shell 100, a pulverizing roller 1 202 is rotatably connected in the pulverizer outer shell 100, a pulverizing roller 2 203 is arranged on one side of the pulverizing roller 1 202, the pulverizing roller 2 203 is rotatably connected in the pulverizer outer shell 100, a support frame 204 is arranged below the pulverizing roller 1 202, and the support frame 204 is fixedly installed on Inside the outer shell 100 of the crusher, lifting chutes 206 are provided on both sides of the support frame 204, and a swing assembly is slidably connected to one side of the support frame 204 for turning and stirring the crushed silicon carbide granular sand. Driving cams 205 are rotatably connected to both sides of the support frame 204, and a lifting slider 208 is fixedly connected to one side of the swing assembly. The lifting slider 208 is slidably connected in the lifting chute 206, and the lower surface of the lifting slider 208 is slidably connected to the driving cam 205. A driving assembly is provided on one side of the driving cam 205 for driving various devices to operate simultaneously; A scattering and impurity removal mechanism 300 is provided on the outer shell 100 of the crusher, and the scattering and impurity removal mechanism 300 includes a storage box 301 fixedly connected to the swing component, and limiting slide grooves 302 are provided on both sides of the storage box 301. Limiting sliders 303 are slidably connected in the limiting slide grooves 302. The upper surface of the limiting slider 303 is fixedly connected with a sliding plate 304, and the lower surface of the sliding plate 304 is evenly installed with scattering slide columns 305. The scattering slide columns 305 are slidably connected in the storage box 301. A magnetic absorption and collection device 306 is slidably connected to one side of the sliding plate 304, and coordination components are rotatably connected at both ends of the sliding plate 304, which are used to push the sliding plate 304 to slide back and forth on the storage box 301 to process silicon carbide granular sand.

[0025] Specifically, the silicon carbide is transported to the feed port 201 by using a conveying device and enters the outer shell 100 of the crusher. The crushing roller 1 202 and the crushing roller 203 in the outer shell 100 of the crusher rotate to crush the silicon carbide. The crushed silicon carbide granular sand will fall into the storage box 301 for storage. The swing component is driven by the driving component to reciprocate along the lifting chute 206, so that the storage box 301 filled with silicon carbide granular sand is reciprocated. While sliding downward, the coordination component will drive the limit slider 303 to slide back and forth in the limit slide groove 302 as the storage box 301 rises and falls, so that the sliding plate 304 drives the breaking slide column 305 to slide to break up the silicon carbide granular sand in the storage box 301, and then the swing component drives the silicon carbide granular sand in the storage box 301 to be turned over, and the silicon carbide granular sand on the bottom layer can be turned over to the upper layer, and the iron impurities doped in the silicon carbide granular sand can be adsorbed by the magnetic absorption and collection device 306.

[0026] The driving component drives the swing component to move up and down along the lifting chute 206, so that the storage box 301 containing silicon carbide granular sand is flipped back and forth. The uniform swinging can effectively prevent the aggregation of silicon carbide granular sand and avoid the adhesion or accumulation between particles, thereby ensuring that the sand particles can flow more freely in the storage box 301 and improving its working performance. While the swing component is lifting and sliding, the coordination component will drive the limit slider 303 to slide back and forth in the limit chute 302 as the storage box 301 is lifted and lowered, so that the sliding plate 304 drives the breaking slide column 305 to slide to break up the silicon carbide granular sand in the storage box 301. The breaking slide column 305 can break up these agglomerated silicon carbide granular sands and maintain the free flow of the sand particles, thereby improving the operability and transmission efficiency of the material.

[0027] Example 2 Reference Figure 1-Figure 6 , Fig. 9 , which is the second embodiment of the present invention, provides a crushing equipment, the swing component includes a lifting plate frame 207, one side of the lifting plate frame 207 is fixedly connected with a lifting slider 208, the other side of the lifting plate frame 207 is rotatably connected with a rotating cam 209, the lifting slider 208 is slidably connected in the lifting slide groove 206, both sides of the rotating cam 209 are fixedly connected with flip plates 210, and a storage box 301 is fixedly installed between the two flip plates 210.

[0028] One side of the lifting plate frame 207 is fixedly connected to a limit stop column 211, and a limit stop column 212 is arranged below the limit stop column 211. One end of the limit stop column 212 is fixedly connected to the side of the lifting plate frame 207. The flip plate 210 will intermittently conflict with the limit stop column 211 and the limit stop column 212 during the swinging process. A flip stop column 213 is fixedly installed on one side of the support frame 204, and a flip stop column 214 is arranged below the flip stop column 213. The flip stop column 214 is fixedly installed on one side of the support frame 204. The flip plate 210 will intermittently conflict with the flip stop column 213 and the flip stop column 214 during the lifting process.

[0029] A fixed block 215 is fixedly installed on the upper surface of the lifting plate frame 207, and a limiting spring piece 216 is fixedly installed in the fixed block 215. A limiting slide column 217 is fixedly installed on the bottom end of the limiting spring piece 216. The limiting slide column 217 is slidably connected in the fixed block 215. The bottom end of the limiting slide column 217 is slidably connected to the surface of the rotating cam 209. The rotating rotating cam 209 can be limited by the limiting slide column 217. A reset spring piece 218 is fixedly installed on the top of the lifting slider 208.

[0030] A mounting plate 219 is fixedly installed on the top of the reset spring 218, and the mounting plate 219 is fixedly connected to one side of the support frame 204. A connecting column 220 is rotatably connected to the support frame 204, and both ends of the connecting column 220 are fixedly connected to a driving cam 205. The driving assembly includes a motor 221 fixedly installed in the outer shell 100 of the grinder, and a rotating disc 222 is provided at the output end of the motor 221.

[0031] A limiting groove 223 is provided on one side of the rotating disc 222, and a driving slide column 224 is arranged below the limiting groove 223. The driving slide column 224 is fixedly connected to the rotating disc 222. A groove wheel 225 is slidably connected to one side of the rotating disc 222. The groove wheel 225 is sleeved on one side of the driving cam 205, and a belt 226 is sleeved on the rotating disc 222.

[0032] The other end of the belt 226 is sleeved with a driving disc 227, one side of the driving disc 227 is fixedly connected to one end of the second crushing roller 203, the other end of the second crushing roller 203 is fixedly connected to a gear 1 228, one side of the gear 1 228 is meshed with a gear 229, and the gear 229 is fixedly connected to one end of the first crushing roller 202.

[0033] Specifically, the output end of the motor 221 drives the rotating disc 222 to rotate, and the rotating disc 222 drives the sleeved belt 226 to drive the crushing roller 203 to rotate. Through the meshing of the gear 1 228 and the gear 2 229, the crushing rollers 1 202 and 203 are driven to rotate to crush the silicon carbide. When the driving slide post 224 on one side of the rotating disc 222 slides into the slide groove in the groove wheel 225, the groove wheel 225 is driven to rotate at the same time. When the groove wheel 225 rotates, it will move from the limit position opened on one side of the rotating disc 222. When the groove 223 passes, when the groove wheel 225 turns over, the driving slide post 224 slides out of the groove of the groove wheel 225. At this time, the arc-shaped side surface of the groove wheel 225 fits with the rotating disk 222, limiting the position of the groove wheel 225. When the groove wheel 225 rotates, it will drive the driving cam 205 on one side to rotate. With the intermittent rotation of the driving cam 205, the lifting slider 208 originally at the bottom of the lifting slide groove 206 is pushed to gradually rise. When the lifting slider 208 slides up and down along the lifting slide groove 206, it compresses the reset spring piece 218, which will drive the support frame 20 The lifting plate frame 207 on the other side slides up. During the process of the lifting plate frame 207 rising, the lifting plate frame 207 first drives the flip plate 210 at one end to collide with the flip stop column 1 213 on the side, driving the rotating cam 209 to rotate on the lifting plate frame 207, so that the limit slide column 217 slides along the surface of the rotating cam 209 to the side where the flip plate 210 is tilted. During the rotation process of the flip plate 210, the lower surface will then collide with the limit stop column 212, so that the storage box 301 between the flip plates 210 on both sides rotates and flips, and the lifting slider 208 slides along the driving cam 2 When the surface of 05 slides to the drop, the driving cam 205 loses the limit on the lifting slider 208, and the compressed reset spring piece 218 will quickly push the lifting slider 208 to slide downward along the lifting slide groove 206 to cause a collision. At the same time, the lifting plate frame 207 descends along the support frame 204, and the steps are opposite. The inclined flip plate 210 will first conflict with the flip stop column 214, and as the rotating cam 209 rotates, it will then conflict with the limit stop column 1 211, causing the storage box 301 between the flip plates 210 on both sides to flip and tilt to the other side, and thus reciprocate.

[0034] Example 3 Reference Figure 1 , Figure 3 , Figure 7 , Figure 8, which is the third embodiment of the present invention, provides a pulverizing device, the coordination component includes a limit plate 1 307 fixedly connected to the inner wall of the pulverizer outer shell 100 on both sides, the limit plate 1 307 is in turn fixedly connected to the limit plate 2 308, the limit plate 2 308 is slidably connected with a transmission rod 309, the other end of the transmission rod 309 is rotatably connected to the sliding plate 304, and the limit plate 1 307 is slidably connected with a sliding shaft 310.

[0035] A guide plate 311 is rotatably connected to the sliding shaft 310, and the other end of the guide plate 311 is rotatably connected to one end of the storage box 301. An inclined coordination cloth 312 is fixedly connected between the two guide plates 311. Mounting blocks 313 are fixedly connected to both ends of the storage box 301. The inner wall of the mounting block 313 is engaged with the flip plate 210. A rotating plate 314 is rotatably connected to the storage box 301. A collecting plate 315 is provided below the storage box 301. The collecting plate 315 is fixedly connected to the inner wall of the crusher outer shell 100. A discharge gate 316 is rotatably connected to the crusher outer shell 100.

[0036] Specifically, the flip plates 210 on both sides are engaged with the coordination cloths 312 on both sides of the storage box 301, driving the storage box 301 to flip while it is lifted and lowered. When the storage box 301 is rising, one end of the transmission rod 309 will gradually slide from the bottom to the top along the limit plate 2 308, and then the transmission rod 309 will push the sliding plate 304 at the other end to slide along the upper surface of the storage box 301, breaking up the silicon carbide granular sand in the storage box 301 so that the silicon carbide granular sand can be better flipped in the storage box 301. When the storage box 301 is lifted and lowered, it will drive the guide plates 311 on both sides. Sliding along the limit plate 307 and adjusting according to the inclination of the storage box 301, the inclined coordination cloth 312 can collect the silicon carbide granular sand that falls to the side into the storage box 301 again, and can smoothly guide the crushed silicon carbide granular sand into the storage box 301. When the impurities are removed, the lifting slider 208 is pushed to the top of the lifting chute 206 by driving the cam 205 to rotate, and the unloading gate 316 on one side of the crusher outer shell 100 is opened. The staff turns the knob under the rotating plate 314 to rotate and open the rotating plate 314, and the silicon carbide granular sand in the storage box 301 is discharged along the collecting plate 315.

[0037] Example 4 Reference Figure 1-Figure 5 , Figure 7 , Figure 8 , which is a fourth embodiment of the present invention, provides an energy-saving crushing method for producing silicon carbide granular sand, comprising the following steps: First, the silicon carbide is transported to the feed port 201 by using a conveying device and enters the outer shell 100 of the crusher. The crushing roller 1 202 and the crushing roller 2 203 in the outer shell 100 of the crusher rotate to crush the silicon carbide. The crushed silicon carbide granular sand will fall into the storage box 301 for storage. The swing component is driven by the driving component to reciprocate along the lifting chute 206, so that the storage box 301 filled with silicon carbide granular sand is flipped back and forth. While sliding, the coordination component will drive the limit slider 303 to slide back and forth in the limit slide groove 302 as the storage box 301 rises and falls, so that the sliding plate 304 drives the breaking slide column 305 to slide to break up the silicon carbide granular sand in the storage box 301, and then the swing component drives the silicon carbide granular sand in the storage box 301 to be turned over, and the silicon carbide granular sand on the bottom layer can be turned over to the upper layer, and the iron impurities doped in the silicon carbide granular sand can be adsorbed by the magnetic absorption and collection device 306.
