Description

Technical Field

[0001] The present application relates to the technical field of crystal raw material crushing, and in particular to a raw material crushing device for pre-treating glycerol thioglycolate. Background Art

[0002] Glyceryl thioglycolate is usually crystalline under high-purity and room-temperature drying conditions. During use, its crystalline raw materials need to be further crushed to meet the requirements of its particle size in the fields of cosmetics, medicine, etc., and thus professional crystal raw material crushing equipment is needed.

[0003] Patent publication number CN219942934U discloses a crystal raw material crushing device. In this prior art, a collecting bucket is arranged below a crushing unit. The crystal raw material crushing device can automatically crush the crystal raw material to improve production efficiency.

[0004] However, the above prior art has the following technical defects:

[0005] First, the existing technology simply relies on hammer crushing, which is suitable for crushing large particles, but has little effect on crushing small particles. Different fields also have requirements for the particle size of glycerol thioglycolate crystals during use. When finer particles are needed, crushing by hammering alone will take a lot of time and slow down production time.

[0006] Second, because the crystal particles of the glycerol thioglycolate crystal raw material are of different sizes, during the hammering process, the crystals on the surface can be broken quickly due to direct hammering, but the large crystal particles in the lower layer are broken slowly, so the staff need to frequently stir the crystals in the inverted truncated table to ensure that the large crystal particles are on the surface, which invisibly increases the workload of the staff. At the same time, the staff cannot avoid being close to the hammer during stirring and are very likely to be injured by the hammer.

[0007] In summary, the prior art still has room for improvement in reducing the workload of workers and allowing the device to crush crystals into smaller particles. Therefore, those skilled in the art have proposed a device that combines hammering and grinding to crush and vibrates the crystal particles during the crushing process. Summary of the invention

[0008] In order to solve the above problems, the present application provides a raw material crushing device for pretreatment of glycerol thioglycolate, which adopts the following technical solution:

[0009] The utility model comprises a bottom plate, a crushing tank is arranged above the bottom plate, and an L-shaped seat is installed on the upper side of the bottom plate at one side of the crushing tank.

[0012] The transmission mechanism further includes a connection assembly connected to the crushing mechanism. When the annular seat rises through the connection assembly, the vibration ring moves up and down multiple times.

[0013] Preferably, the crushing mechanism further includes a mounting plate installed on the lower side of the L-shaped seat and on one side of the drive shaft of the grinding motor. Bevel gears meshing with each other are installed on the side of the mounting plate and the drive end of the grinding motor.

[0017] Preferably, a rectangular plate is installed on the side of the L-shaped seat. A gear two is rotatably installed on one side of the rectangular plate. A rack one meshing with the gear two is slidably arranged on the square rod.

[0018] Preferably, a half gear is arranged on the other side of the rectangular plate. A one-way clutch is installed between the rotating shaft of the gear two and the half gear. A rack two meshing with the half gear is installed on the upper side of the T-shaped plate.

[0019] Preferably, a transmission mechanism is further provided on the L-shaped seat. The transmission mechanism includes an L-shaped frame moving on one side of the L-shaped seat. A connection frame slidably connected to the rack one is installed on the front side of the L-shaped frame.

[0020] Preferably, an upper gear is installed on the side of the L-shaped frame near the gear, and a lower gear is installed on the side of the L-shaped frame near the second gear. A belt connection is provided between the upper gear and the lower gear.

[0024] Second, through the cooperation of the crushing mechanism and the vibration mechanism, during the crushing process, the vibration ring continuously impacts the crushing tank, causing the crystals inside to vibrate. Large particles are continuously "lifted" from below by small particles during vibration and finally gather on the surface layer, so that they can be the first to be hammered or ground by the grinding disc, improving the crushing effect. At the same time, it is not necessary for the staff to stir the crystals, reducing the labor intensity of the staff and protecting the staff. At the same time, by adopting the effect of impacting from bottom to top, the crystals vibrate up and down, enhancing the convective movement between the crystals, accelerating the rise of large particles and the settlement of small particles, and significantly enhancing the stratification efficiency of the particle system.

[0039] The following will be combined with Figure 1 - Figure 12 to describe the embodiments of this application in detail.

[0040] The embodiment of the present application discloses a raw material crushing device for the pretreatment of glycerol thioglycolate. By setting a crushing mechanism with two crushing methods, the present application first uses a grinding disc that moves up and down to hammer and crush glycerol thioglycolate crystals, so that large - particle crystals can be quickly broken. Then, the rotating grinding disc is used to grind small - particle crystals into finer crystals. By combining the two crushing methods and giving full play to their respective advantages, large - particle crystals can be quickly broken, and small - particle crystals can be quickly ground and crushed into fine particles, improving the crushing efficiency, enabling the device to adapt to the grinding of multiple small - particle sizes, and increasing the applicable range of the device.

[0041] Embodiment 1:

[0042] As Figure 1 shown, it includes a bottom plate 1. Two Z - shaped frames 6 are symmetrically installed on the upper side of the bottom plate 1. A tank seat 7 with an open lower side is installed between the two Z - shaped frames 6. A crushing tank 8 adapted to it is arranged on the tank seat 7. The tank seat 7 is used to hold the crushing tank 8. Put glycerol thioglycolate crystals into the crushing tank 8, and then use the device for crushing.

[0043] As Figure 1 shown, a fixed electric cylinder 9 is also installed on the side of the Z - shaped frame 6. A clamp seat 10 adapted to the crushing tank 8 is installed at the end of the fixed electric cylinder 9. An L - shaped seat 11 is installed on the upper side of the bottom plate 1 on one side of the tank seat 7. When the two fixed electric cylinders 9 extend, the two clamp seats 10 approach each other to clamp the crushing tank 8, and then when the fixed electric cylinder 9 shortens, the clamping can be released.

[0044] As Figures 2 - 5 shown, a crushing mechanism 2 is arranged on the L - shaped seat 11. The crushing mechanism 2 includes a grinding disc 201 located directly above the crushing tank 8 and having a diameter adapted to its inner diameter. A rotating groove with a T - shaped cross - section is opened on the upper side of the grinding disc 201. An annular seat 204 with an H - shaped cross - section and adapted to it is rotatably arranged in the rotating groove. A hammering cylinder 203 with its lower end connected to the annular seat 204 is installed on the lower side of the L - shaped seat 11. The telescopic movement of the hammering cylinder 203 drives the grinding disc 201 to move up and down to hammer and crush the glycerol thioglycolate crystals in the crushing tank 8. At the same time, the annular seat 204 is slidably connected to the grinding disc 201, and the rotating grinding disc 201 will not drive the annular seat 204 to rotate.

[0045] As Figure 4As shown in the figure, a grinding motor 202 is installed on the upper side of the L-shaped seat 11. A round tube 205 is installed at the driving end of the grinding motor 202. A secondary rod 211 with its lower end connected to the grinding disc 201 is slidably arranged in the round tube 205. Two strip-shaped grooves 206 are symmetrically formed on the side surface of the round tube 205. A limiting block 207 connected to the secondary rod 211 is slidably arranged in the strip-shaped groove 206. The operating grinding motor 202 drives the grinding disc 201 through the cooperation of the round tube 205 and the secondary rod 211 to grind and crush the thioglycolic acid glycerol ester crystals in the crushing tank 8. At the same time, the grinding disc 201 moving up and down drives the two limiting blocks 207 to slide in the strip-shaped grooves 206 through the secondary rod 211.

[0046] In summary, put the thioglycolic acid glycerol ester crystals into the crushing tank 8, and then place the crushing tank 8 on the tank seat 7. The two fixed electric cylinders 9 extend to drive the clamping seats 10 to clamp and fix the crushing tank 8. Then, the hammering cylinder 203 continuously expands and contracts to drive the grinding disc 201 to hammer and crush the thioglycolic acid glycerol ester crystals in the crushing tank 8. After the large-particle crystals are crushed, the hammering cylinder 203 stops, and the grinding motor 202 operates to drive the grinding disc 201 to rotate through the cooperation of the round tube 205 and the secondary rod 211 to grind and crush the thioglycolic acid glycerol ester crystals in the crushing tank 8, grinding the thioglycolic acid glycerol ester crystals into smaller particles.

[0047] As Figures 6 - 7 shown in the figure, it further includes a vibration mechanism 3. The vibration mechanism 3 includes a vibration ring 305 located directly below the tank seat 7. A T-shaped plate 301 is installed on the lower side of the vibration ring 305. Two vertical rods 302 penetrating through the two Z-shaped frames 6 are symmetrically installed on the upper side of the T-shaped plate 301. A second limiting member 303 is installed at the upper end of the vertical rod 302. A vibration spring 304 is arranged between the second limiting member 303 and the Z-shaped frame 6. The descending T-shaped plate 301 compresses the vibration spring 304 through the second limiting member 303, and then the vibration spring 304 rebounds to drive the T-shaped plate 301 and the vibration ring 305 to rise, using the vibration ring 305 to impact the lower end of the crushing tank 8 to vibrate the thioglycolic acid glycerol ester crystals in the crushing tank 8.

[0048] At the same time, when the thioglycolic acid glycerol ester crystals in the crushing tank 8 vibrate, the small particles have stronger fluidity and will preferentially fill the voids at the bottom, making them in the lower layer, resulting in the large particles losing the space to sink. The large particles are continuously "lifted" from below by the small particles during vibration and finally gather on the surface layer, so that they can be the first to be hammered or ground by the grinding disc 201.

[0049] As Figures 7 - 8As shown, an L-shaped plate 308 is installed on the upper side of the annular seat 204. A moving groove is provided on the upper side of the L-shaped plate 308. A square rod 310 is installed in the moving groove. A rectangular plate 306 is installed on the side of the L-shaped seat 11. A second gear 307 is rotatably installed on one side of the rectangular plate 306. A first rack 309 that meshes with the second gear 307 is slidably arranged on the square rod 310. The ascending and descending first rack 309 can drive the second gear 307 to rotate forward and backward.

[0050] As Figures 7 - 8 As shown, a semi-gear 312 is arranged on the other side of the rectangular plate 306. A one-way clutch 311 is installed between the rotating shaft of the second gear 307 and the semi-gear 312. A second rack 313 that meshes with the semi-gear 312 is installed on the upper side of the T-shaped plate 301. The rotating second gear 307 drives the semi-gear 312 to rotate through the one-way clutch 311. The rotating semi-gear 312 drives the T-shaped plate 301 to descend through the second rack 313. After the second rack 313 disengages from the second rack 313, the ascending T-shaped plate 301 drives the second rack 313 to restore its position. After that, the rotating semi-gear 312 meshes with the second rack 313 again to continue the above operation, realizing that the semi-gear 312 rotates one circle and the T-shaped plate 301 descends once. The reverse-rotating second gear 307 will not drive the semi-gear 312 to rotate through the one-way clutch 311.

[0051] In summary, during the continuous up-and-down movement of the grinding disc 201 to hammer the crystal, the ascending grinding disc 201 drives the first rack 309 to ascend, drives the semi-gear 312 to rotate through the second gear 307 and the one-way clutch 311. The rotating semi-gear 312 drives the T-shaped plate 301 to descend through the second rack 313. The descending T-shaped plate 301 compresses the vibration spring 304 through the second limiting member 303. When the second rack 313 disengages from the second rack 313, the vibration spring 304 rebounds to drive the T-shaped plate 301 and the vibration ring 305 to ascend, and uses the vibration ring 305 to impact the lower end of the crushing tank 8, causing the glycerol thioglycolate crystal in the crushing tank 8 to vibrate, moving the large-particle crystals to the surface layer and being hammered first, improving the crushing effect. At the same time, it will also drive the second rack 313 to restore its position. After that, the rotating semi-gear 312 meshes with the second rack 313 again to continue the operation, realizing that the semi-gear 312 rotates one circle and impacts the crushing tank 8 once. At the same time, the ascending first rack 309 can drive the second gear 307 to rotate multiple circles. Therefore, during one upward movement of the grinding disc 201, the crushing tank 8 can be impacted multiple times. When the first rack 309 descends to drive the second gear 307 to reverse, the one-way clutch 311 will not drive the semi-gear 312 to reverse.

[0052] As Figure 4As shown, the crushing mechanism 2 further includes a mounting plate 208 installed on the lower side of the L-shaped seat 11 and on one side of the drive shaft of the grinding motor 202. Bevel gears 209 that mesh with each other are installed on the side surface of the mounting plate 208 and the drive end of the grinding motor 202. A first gear 210 is installed at the end of the rotating shaft of the bevel gear 209 on the mounting plate 208. The operating grinding motor 202 drives the first gear 210 to rotate through the two bevel gears 209.

[0053] As Figure 6 and Figure 9 As shown, a transmission mechanism 4 is further provided on the L-shaped seat 11. The transmission mechanism 4 includes a plurality of moving electric cylinders 401 symmetrically installed on the other side surface of the L-shaped seat 11. An L-shaped frame 402 is jointly installed at the ends of the plurality of moving electric cylinders 401. A slide bar 407 is installed on the side surface of the first rack 309. A connecting frame 408 connected to the L-shaped frame 402 is slidably arranged on the slide bar 407. The telescopic movement of the moving electric cylinder 401 can drive the L-shaped frame 402 to move. Since the first rack 309 slides on the square rod 310, the moving L-shaped frame 402 can also drive the first rack 309 to move horizontally through the connecting frame 408 and the slide bar 407.

[0054] As Figure 6 and Figure 9 As shown, an upper gear 403 is installed on the side surface of the L-shaped frame 402 near the first gear 210, and a lower gear 404 is installed on the side surface of the L-shaped frame 402 near the second gear 307. Synchronous pulleys 405 are installed at the ends of the rotating shafts of the upper gear 403 and the lower gear 404. A synchronous belt 406 is provided on the two synchronous pulleys 405. Adjust the position of the L-shaped frame 402 to make the upper gear 403 mesh with the first gear 210 and the lower gear 404 mesh with the second gear 307. Then, the rotating square rod 310 drives the meshing upper gear 403 to rotate, drives the lower gear 404 to rotate through the synchronous pulleys 405 and the synchronous belt 406, and then drives the meshing second gear 307 to rotate.

[0055] In summary, after the hammering is completed, the moving electric cylinder 401 extends to drive the L-shaped frame 402 to move, so that the upper gear 403 meshes with the first gear 210, and the lower gear 404 meshes with the second gear 307. At the same time, the first rack 309 is driven to move horizontally to disengage from the second gear 307. After that, when the grinding motor 202 drives the grinding disc 201 to rotate for grinding the crystal, the first gear 210 is driven to rotate by the two bevel gears 209. The rotating square rod 310 drives the meshing upper gear 403 to rotate, and drives the lower gear 404 to rotate through the synchronous pulley 405 and the synchronous belt 406. Then, the meshing second gear 307 is driven to rotate. The rotating second gear 307 can make the vibration ring 305 continuously impact the crushing tank 8, causing the crystals in the crushing tank 8 to vibrate, ensuring that the larger particle crystals continuously move upward to contact the grinding disc 201, accelerating the grinding and crushing. After the grinding is completed, the moving electric cylinder 401 shortens to drive the L-shaped frame 402 to move in the reverse direction, so that the upper gear 403 disengages from the first gear 210 and the lower gear 404 disengages from the second gear 307. At the same time, the first rack 309 re-engages with the second gear 307 to prepare for the next hammering.

[0056] Embodiment 2:

[0057] On the basis of Embodiment 1, as Figure 5 and Figure 10 shown, an inner cavity 212 is formed inside the grinding disc 201, and a mounting disc 213 adapted thereto is slidably arranged in the inner cavity 212. A plurality of uniformly distributed bumps 214 extending to the lower surface of the grinding disc 201 are installed on the lower side of the mounting disc 213. During the grinding process, each bump 214 is extended to improve the grinding effect. During the hammering process, the mounting disc 213 is raised so that the lower ends of the bumps 214 are flush with the lower surface of the grinding disc 201, avoiding crystal particles being stuck between adjacent bumps 214 during the hammering process.

[0058] As Figure 10 shown, two extension rods 217 extending to the outside of the grinding disc 201 are symmetrically installed on the upper side of the mounting disc 213. A first limiting member 218 is installed at the upper end of the extension rod 217. A return spring 219 is connected between the first limiting member 218 and the grinding disc 201. The rising mounting disc 213 drives the first limiting member 218 to rise through the extension rod 217, and the rising first limiting member 218 stretches the return spring 219. When the return spring 219 rebounds, it will drive the mounting disc 213 to return to its original position.

[0059] As Figure 5As shown, a plurality of through holes 215 that are circumferentially and uniformly distributed and communicate with the inner cavity 212 are provided on the upper side of the grinding disc 201. A sealing cover 216 is rotatably installed above all the through holes 215 on the upper side of the grinding disc 201. An expansion rod connected to the L-shaped seat 11 is installed on the upper side of the sealing cover 216. A vertical pipe is also installed on the upper side of the sealing cover 216, and a solenoid valve is installed on the vertical pipe. The sealing cover 216 communicates with the inner cavity 212 through the through holes 215. The rotating grinding disc 201 will not drive the sealing cover 216 to rotate through the telescopic pipe. When the solenoid valve is opened, the sealing cover 216 can be communicated with the outside.

[0060] As Figure 11 and Figure 12 shown, a negative pressure mechanism 5 is further provided on the side surface of the L-shaped seat 11. The negative pressure mechanism 5 includes an air cylinder 501. A piston 502 adapted to it is slidably arranged in the air cylinder 501. An extension frame 503 is installed on the side surface of the piston 502 and extends to the outside of the air cylinder 501 and bends to be connected to the L-shaped frame 402. When the L-shaped frame 402 moves, the piston 502 is driven to move through the extension frame 503.

[0061] As Figure 5 and Figure 12 shown, two air pipes 504 are symmetrically installed on the side surface of the air cylinder 501 near both ends. A connecting hose 505 communicating with the sealing cover 216 is also installed on the side surface of the air cylinder 501. Check valves 506 are provided on both the connecting hose 505 and the air pipe 504 close to it. The check valve 506 on the connecting hose 505 can only allow the gas in the sealing cover 216 to enter the air cylinder 501, and the check valve 506 on the air pipe 504 can only allow the gas in the air cylinder 501 to be discharged through the air pipe 504.

[0062] In summary, during hammering and crushing, it is necessary to move the electric cylinder 401 to shorten first, so that the moving L-shaped frame 402 drives the first rack 309 to engage with the second gear 307. At this time, the moving L-shaped frame 402 drives the vertical rod 302 to move through the second limiting member 303. The moving vertical rod 302 pumps the gas in the inner cavity 212 into the air cylinder 501 through the connecting hose 505, creating a negative pressure in the inner cavity 212. The external air pressure presses the mounting plate 213 to rise, so that the convex points 214 retract into the inner cavity 212 until they are flush with the lower side of the grinding disc 201. At the same time, the rising mounting plate 213 stretches the return spring 219 through the first limiting member 218. Then, during grinding and crushing, the solenoid valve on the vertical pipe is opened to relieve the negative pressure in the inner cavity 212. The return spring 219 shortens to drive the mounting plate 213 to return to its original position, so that the convex points 214 protrude.

[0063] If the vertical rod 302 cannot be moved once to raise the convex point 214 to the same level as the lower surface of the grinding disc 201, the electric cylinder 401 can be continuously telescoped and moved to drive the vertical rod 302 to continuously move back and forth in the T-shaped plate 301. The moving vertical rod 302 will pump the gas in the inner cavity 212 into the T-shaped plate 301, and then the vertically rod 302 moving in the reverse direction will discharge the gas from the trachea 504. After that, the operation is repeated until the lower end of the convex point 214 is flush with the grinding disc 201.

[0064] The present application also discloses a method for using a raw material crushing device for the pretreatment of glycerol thioglycolate, and the steps of the method are as follows:

[0065] S1. Hammer crushing: Use the crushing mechanism 2 to hammer-crush the glycerol thioglycolate crystals in the crushing tank 8. Specifically, put the glycerol thioglycolate crystals into the crushing tank 8, and then place the crushing tank 8 on the tank seat 7. The two fixed electric cylinders 9 extend to drive the clamping seat 10 to clamp and fix the crushing tank 8. Then, the hammering cylinder 203 continuously extends and retracts to drive the grinding disc 201 to hammer-crush the glycerol thioglycolate crystals in the crushing tank 8, and the large-particle crystals are crushed into small-particle crystals.

[0066] S2. Crystal vibration: When the crushing mechanism 2 hammers the crystals, cooperate with the vibration mechanism 3 to vibrate the crystals in the crushing tank 8, so that the large-particle crystals are on the surface layer. Specifically, during the process that the grinding disc 201 continuously moves up and down to hammer the crystals, the rising grinding disc 201 drives the first rack 309 to rise, drives the half gear 312 to rotate through the second gear 307 and the one-way clutch 311, and the rotating half gear 312 drives the T-shaped plate 301 to descend through the second rack 313. The descending T-shaped plate 301 compresses the vibration spring 304 through the second limiting member 303. When the second rack 313 disengages from the second rack 313, the vibration spring 304 rebounds to drive the T-shaped plate 301 and the vibration ring 305 to rise, and uses the vibration ring 305 to impact the lower end of the crushing tank 8 to vibrate the glycerol thioglycolate crystals in the crushing tank 8, so that the large-particle crystals gather on the surface layer and are hammered first, improving the crushing effect.

[0067] S3. Grinding and crushing: Specifically, continue to grind and crush the crystals in the crushing tank 8 through the crushing mechanism 2. Specifically, the hammering cylinder 203 extends to drive the grinding disc 201 to descend until it presses the crystals in the crushing tank 8. Then, the grinding motor 202 operates to drive the grinding disc 201 to rotate through the cooperation of the round tube 205 and the auxiliary rod 211, and grind and crush the glycerol thioglycolate crystals in the crushing tank 8, and grind the glycerol thioglycolate crystals into smaller particles.

[0068] S4. Structural transformation: During the rotation of the grinding disc 201 by the transmission mechanism 4, the crystals in the crushing tank 8 can still be vibrated. Specifically, after the hammering is completed, the moving electric cylinder 401 extends to drive the L-shaped frame 402 to move, so that the upper gear 403 meshes with the first gear 210, and the lower gear 404 meshes with the second gear 307. At the same time, it drives the first rack 309 to move horizontally to disengage from the second gear 307. Then, when the grinding motor 202 drives the grinding disc 201 to rotate and grind the crystals, the first gear 210 is driven to rotate by the two bevel gears 209. The rotating square rod 310 drives the meshing upper gear 403 to rotate, drives the lower gear 404 to rotate through the synchronous pulley 405 and the synchronous belt 406, and then drives the meshing second gear 307 to rotate. The rotating second gear 307 can make the vibration ring 305 continuously impact the crushing tank 8, causing the crystals in the crushing tank 8 to vibrate, ensuring that the larger particle crystals continuously move upward to contact the grinding disc 201, and accelerating the grinding and crushing.

[0069] S5. Pouring out the crystals: Pour out the crushed crystals in the crushing tank 8. Specifically, grind until the crystal particles reach the predetermined size, then turn off the grinding motor 202. The two fixed electric cylinders 9 shorten to drive the clamping seats 10 to move away from each other to release the clamping of the crushing tank 8. Then, remove the crushing tank 8 and pour out the crystal particles after crushing the crystals inside.
