Description

Technical Field

[0001] The invention relates to the technical field of silicon micropowder production, in particular to a grading pulverizing device for silicon micropowder production and processing. Background Art

[0002] Silica powder generally refers to quartz powder, which is made from pure quartz (natural quartz or fused quartz) through multiple processes such as crushing, sorting, cleaning, acid treatment, high-temperature melting, pulverizing, fine grinding, grading, and iron removal to produce a powder that meets the requirements of use.

[0003] The pulverizing equipment used in the preparation of traditional silicon micropowder has the following shortcomings: first, the traditional grinder generally grinds and pulverizes once, and the particles obtained after pulverization are relatively large, which requires primary pulverization, which requires re-pour into the grinder and grinding again, so the grinding time is long; secondly, in the process of processing silicon micropowder with traditional grinders, the raw materials are mostly poured in continuously, resulting in poor grinding effect, and the grading, screening and pulverization cannot be performed, which easily causes large particles to be mixed in the finished silicon micropowder, and it is necessary to screen them to obtain silicon micropowder that meets the requirements.

After the crushing plate rotates to crush the crushed materials, the crushed materials fall into the spinner plate again along the inclined protrusions, thereby achieving the effect of grading, screening and crushing.

[0019] 2. In the grading and crushing equipment for the production and processing of silicon micropowder, the crushed materials remaining on the surface of the throwing plate are thrown out under the action of centrifugal force, and the crushed materials remain in the triangular gap formed by the conical ring and the grinding barrel. Since the top pressure rod is connected to the driving shaft, the top pressure rod performs multi-circular motion, and the special-shaped protrusions and extrusion blocks arranged on the top and outer ends of the top pressure rod will squeeze and crush the crushed materials. The crushed materials fall onto the surface of the sieve plate, and are then crushed and crushed by the use of the rolling assembly.

[0039] Specifically, a connecting frame 11 is provided on the inner side of the shredding disc 10, and the connecting frame 11 is arranged equidistantly in a triangle.

A circular hole is provided at the bottom of the shredding disc 10, and the shredding disc 10 is sleeved on the outer side of the driving shaft 8. An arc-shaped protrusion is provided on the bottom surface of the shredding disc 10.

[0040] In the present embodiment, a connecting frame 11 is provided to connect the pulverizing disk 10, wherein the pulverizing disk 10 is sleeved and arranged on the outer side of the driving shaft 8. When the driving shaft 8 is driven by the pulverizing motor 4 to rotate, the connecting frame 11 and the pulverizing disk 10 are driven to perform circular motion. The arc-shaped protrusion on the bottom surface of the pulverizing disk 10 is used to pulverize the silicon micro-crushed material (hereinafter collectively referred to as crushed material) accumulated on the surface of the distribution disk 16. The pulverizing disk 10 moves toward the distribution disk 16 under the repulsive action of the magnetic block 13. Since the distribution disk 16 is in a stationary state and the pulverizing disk 10 is dynamic, the protrusion on the bottom of the pulverizing disk 10 will cooperate with the inclined protrusion 22 provided on the surface of the distribution disk 16 to extrude and pulverize the crushed material remaining on the surface of the distribution disk 16.

[0041] Specifically, the pulverizing disk 10 is arranged in an inverted cone shape, wherein an electromagnet is arranged in the middle of the pulverizing disk 10, and a magnetic block 13 is arranged on the outside of the driving shaft 8, and the magnetic block 13 and the electromagnet are parallel to each other and have the same relative magnetic poles.

[0042] In this embodiment, the crushing disk 10 is set to an inverted cone shape to fit with the distribution disk 16, so that the crushed materials remaining on the surface of the distribution disk 16 can be crushed, and the crushed crushed materials fall downward along the inclined surface of the distribution disk 16 and enter the surface of the spinner 15. The electromagnet arranged in the middle of the crushing disk 10 is energized by contacting the electrode sheet arranged on the inner wall of the crushing barrel 6. When the electromagnet is energized to generate a magnetic field, it will be repelled by the magnetic block 13 and move downward along the outer side of the drive shaft 8, thereby achieving extrusion and crushing of the remaining crushed materials.

[0043] Specifically, the sorting assembly includes a connecting rod 24, an annular hole 23, a spinning disc 15, and a curved surface 21. One end of the connecting rod 24 is movably mounted on the inner wall of the ring 12, and the other end is fixedly mounted on the surface of the spinning disc 15. The spinning disc 15 is arranged in the middle of the ring 12. The curved surface 21 is opened on the surface of the spinning disc 15, and the spinning disc 15 is fixedly connected to the outer side of the drive shaft 8.

[0044] In this embodiment, a connecting rod 24 is provided to connect the spinning disc 15 and the ferrule 12, wherein the spinning disc 15 performs a circular motion along the inside of the ferrule 12 under the drive of the drive shaft 8, wherein the inner wall of the ferrule 12 is provided with an inclined surface, and the crushed materials thrown out by the spinning disc 15 fall below through the annular hole 23 under the action of the inclined surface, and the surface of the spinning disc 15 is smooth, wherein the curved surface 21 serves to guide the crushed materials to avoid the accumulation of the crushed materials, and the crushed materials remaining on the surface of the spinning disc 15 are thrown out under the action of the centrifugal force.

[0045] Specifically, the sorting component further includes a material distribution plate 16 and inclined surface protrusions 22 . The material distribution plate 16 is fixedly mounted on the top of the ferrule 12 , and the inclined surface protrusions 22 are equidistantly arranged on the inclined surface of the material distribution plate 16 in a circumferential manner.

[0046] In the present embodiment, a distribution plate 16 is provided to disperse the crushed materials, and the crushed materials are fed through the feed hopper 5. After feeding, the smaller crushed materials fall down along the slope of the distribution plate 16 to the spinner plate 15 under the limitation of the sloped protrusions 22, and the larger crushed materials stay between the sloped protrusions 22. The protrusions at the bottom of the crushing plate 10 cooperate with the sloped protrusions 22 provided on the surface of the distribution plate 16 to squeeze and crush the large-particle crushed materials staying on the surface of the distribution plate 16. After the crushing plate 10 rotates to crush the crushed materials, the crushed materials fall into the spinner plate 15 again along the sloped protrusions 22.

[0047] Specifically, the primary crushing assembly includes a conical ring 14, a pressure rod 19, a special-shaped protrusion 28, and an extrusion block 27. The top end of the conical ring 14 is fixedly installed with the bottom end of the ferrule 12. The conical ring 14 is arranged in a conical shape. The conical ring 14 and the inner wall of the grinding barrel 7 form a triangular gap. The pressure rod 19 is fixedly installed on the outer side of the driving shaft 8. The special-shaped protrusion 28 is opened at the top end of the pressure rod 19. The extrusion block 27 is opened at the outermost end of the pressure rod 19. The rolling assembly is arranged at the bottom end of the pressure rod 19. The special-shaped protrusion 28 and the extrusion block 27 are in contact with the inner side of the conical ring 14.

[0048] In this embodiment, a conical ring 14 is provided to extrude and crush the crushed materials thrown out by the throwing plate 15. The top pressure rod 19 moves in a circular motion driven by the drive shaft 8. The extrusion block 27 and the special-shaped protrusion 28 squeeze the side of the conical ring 14, thereby squeezing and crushing the crushed materials remaining in the triangular gap. The crushed materials after extrusion and crushing fall onto the surface of the sieve plate 18, and are then crushed and crushed by the cooperation of the crushing assembly.

[0049] Specifically, the rolling assembly includes a grinding roller 20, a mounting frame 30, a telescopic hole 29, and a spring column 31. The mounting frame 30 is fixedly mounted on the bottom end of the top pressure rod 19, the grinding roller 20 is movably mounted on the inner side of the mounting frame 30, the telescopic hole 29 is opened on the outer surface of the grinding roller 20, and the spring column 31 is movably mounted on the inner wall of the telescopic hole 29.

[0050] In this embodiment, a grinding roller 20 is provided to crush the crushed materials on the surface of the sieve plate 18, a mounting frame 30 is used to install the grinding roller 20, and a telescopic hole 29 is used to install a spring column 31. When the grinding roller 20 rotates, the spring column 31 is driven to rotate. The spring column 31 is squeezed by the sieve plate 18 and contracts to the inside of the telescopic hole 29. The spring at one end of the spring column 31 is compressed. When the spring column 31 is ejected by the spring, it is plugged into the sieve hole of the sieve plate 18, thereby conveying the crushed crushed materials to the grinding assembly, wherein the spring column 31 is made of rubber material.

[0051] Specifically, the grinding assembly includes an extrusion protrusion 17 and a grinding column 9 . The extrusion protrusion 17 is opened on the inner side of the grinding barrel 7 . The grinding column 9 is movably installed on the inner wall of the grinding barrel 7 . The grinding column 9 is fixedly installed on the outer side of the driving shaft 8 .

[0052] In this embodiment, an extrusion protrusion 17 is provided to cooperate with the grinding column 9 to grind the crushed material screened by the sieve plate 18. The grinding column 9 moves in a circular motion driven by the driving shaft 8, thereby grinding the crushed material entering the gap between the grinding column 9 and the grinding barrel 7 into powder, and the ground powder falls into the bottom of the grinding barrel 7 for storage.

[0053] Specifically, the grinding assembly also includes an inner groove 25 and a crushing tip 26. The inner groove 25 is opened on the outer side of the grinding column 9 and is used in conjunction with the extrusion protrusion 17. The crushing tip 26 is opened on the outer side of the grinding column 9 and is located above the inner groove 25. The crushing tip 26 is used in conjunction with the grinding barrel 7.

[0054] In this embodiment, an inner groove 25 is provided to cooperate with the extrusion protrusion 17 provided on the inner side of the grinding barrel 7. When the grinding column 9 rotates, the crushed materials fall into the gap of the inner groove 25. The relative movement of the extrusion protrusion 17 and the grinding column 9 rubs the crushed materials to form powder. The crushing tip 26 provided near the top of the grinding column 9 is used to extrude and crush the crushed materials so that they enter the inner groove 25 to complete the grinding.

[0055] Specifically, the sieve plate 18 is fixedly mounted on the inner wall of the grinding barrel 7 , the sieve plate 18 is sleeved on the outer side of the driving shaft 8 , and sieve holes are equidistantly formed on the bottom of the sieve plate 18 .

[0056] In this embodiment, circular holes are opened on the surface of the sieve plate 18 to screen the crushed materials after passing through the conical ring 14, so that the crushed materials smaller than the sieve holes fall down for grinding, and the crushed materials larger than the sieve holes stay on the surface, waiting to be crushed by the grinding roller 20 and fall down again for grinding.

[0057] When in use, the driving shaft 8 is driven to rotate by energizing the pulverizing motor 4, and the adsorption pump at one end of the adsorption tube 2 is energized to be in operation, and then the silicon micro-grinding material to be pulverized is put into the feed hopper 5, and the crushed material enters the interior of the pulverizing barrel 6 along the feed hopper 5. Since the distribution plate 16 is located below the discharge port of the feed hopper 5, the crushed material gathers toward the middle along the inclined surface of the distribution plate 16. After being put in, the smaller crushed material falls to the throwing plate 15 along the inclined surface of the distribution plate 16 under the limit of the inclined surface protrusion 22, and the larger crushed material stays on the inclined surface protrusion 22. Then, by energizing the electromagnet in the middle of the pulverizing disk 10, the electromagnet generates a magnetic field, and the electromagnet in the middle of the pulverizing disk 10 is repelled by the magnetic block 13, and moves downward along the outer side of the driving shaft 8 close to the distribution disk 16. Since the pulverizing disk 10 follows the driving shaft 8 to make a circular motion, the remaining crushed materials are squeezed and crushed, wherein the protrusion at the bottom of the pulverizing disk 10 cooperates with the inclined protrusion 22 provided on the surface of the distribution disk 16 to squeeze and crush the large-particle crushed materials remaining on the surface of the distribution disk 16, and the pulverizing disk 10 rotates to grind the crushed materials After crushing, the crushed materials fall into the throwing plate 15 again along the inclined surface protrusion 22. The crushed materials thrown out of the throwing plate 15 fall into the lower part through the annular hole 23 under the action of the inclined surface. The surface of the throwing plate 15 is smooth, and the curved surface 21 plays a role in guiding the crushed materials to avoid the accumulation of crushed materials. The crushed materials remaining on the surface of the throwing plate 15 are thrown out under the action of centrifugal force, and the crushed materials remain in the triangular gap formed by the conical ring 14 and the grinding barrel 7. Since the push rod 19 is connected to the driving shaft 8, the push rod 19 moves in multiple circles, and the top and outer ends of the push rod 19 are provided with different The shaped protrusions 28 and the extrusion blocks 27 will extrude and crush the crushed materials. After being extruded and crushed, the crushed materials fall onto the surface of the sieve plate 18, and are then crushed and crushed by the rolling assembly. The crushed materials smaller than the sieve holes of the sieve plate 18 fall onto the grinding assembly for grinding, and the crushed materials larger than the sieve holes stay on the surface, waiting to be crushed by the grinding roller 20, and then fall down again for grinding. The grinding column 9 in the grinding assembly, driven by the drive shaft 8, finely grinds the crushed materials sandwiched between the grinding column 9 and the grinding barrel 7 to obtain finer silicon micropowder.
