AI Technical Summary
The existing feeding structure of the metal silicon grinding device cannot be shaken or vibrated, which causes some of the smaller silicon particles to remain on the filter screen and eventually be separated into the larger silicon particles, resulting in poor separation effect.
A feeding structure including a speed control component, a vibration component, and a disassembly component was designed. By adjusting the inclination of the feeding channel and the vibrating coarse screen box, effective separation of silicon powder is achieved, ensuring that silicon powder with a suitable particle size is discharged through the coarse screen box, while silicon powder with a larger particle size is processed separately.
This improves the efficiency of subsequent screening, avoids small-sized silica powder residue on the filter screen, and enhances the separation effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding structure technology, and in particular to a feeding structure for a metal silicon grinding device. Background Technology
[0002] In the production of silicon powder, since metallic silicon is generally smelted from quartz and coke, it contains impurities such as iron, aluminum and calcium, resulting in uneven particle size after grinding. When feeding through the feeding structure or after feeding, it needs to be screened. However, the feeding structure of existing metallic silicon grinding equipment is not capable of screening. The feeding is screened directly, which results in low screening efficiency due to the severe uneven particle size.
[0003] Prior art CN212798743U discloses a feeding device for metallic silicon powder, including a base, two support rods, two screws, two lead screw seats, two rotating rods, a feeding bin, a filter screen, a connecting rod, a first motor, a second motor, two first bevel gears, and two second bevel gears. The two support rods are fixedly connected to the top of the base, the two screws are rotatably connected to the base, the two lead screw seats are threadedly connected to the two screws respectively and located above the base, one rotating rod is slidably connected to a support rod and rotatably connected to one side of the lead screw seat, the feeding bin is fixedly connected to the end of the rotating rod away from the lead screw seat, the filter screen is fixedly connected to the feeding bin, the connecting rod is fixedly connected to one side of the other lead screw seat, the first motor is fixedly connected to the end of the connecting rod away from the lead screw seat, and the other rotating rod is fixedly connected to the feeding bin and the output end of the first motor. Between the two screws, a second motor is fixedly connected to the bottom of the base and has a rotating shaft. Two first bevel gears are fixedly connected to the two ends of the rotating shaft, and two second bevel gears are fixedly connected to the bottom of the two screws and mesh with the two first bevel gears respectively. When feeding, the second motor is started, and through the cooperation of the two first bevel gears and the two second bevel gears, the two screws are rotated, causing the two lead screw seats to rise and fall. Under the action of the connecting rod, the first motor and the two rotating rods, the feeding hopper is driven to rise and fall until the feeding hopper is in the right position, and feeding begins. Silicon powder with a suitable particle size will be discharged through the filter screen, while larger particles will remain in the feeding hopper. Finally, the first motor is started, and under the action of the two rotating rods, the feeding hopper is flipped to discharge the larger particles, thus obtaining coarsely screened silicon powder during feeding and improving the efficiency of subsequent screening.
[0004] However, the filter screen of the existing silicon powder feeding device cannot be shaken or vibrated, so some silicon powder with smaller particle size will remain on the filter screen and eventually be separated into silicon powder with larger particle size, resulting in poor separation effect. Utility Model Content
[0005] The purpose of this invention is to provide a feeding structure for a silicon metal grinding device, which aims to solve the problem that the filter screen of the existing silicon metal powder feeding device cannot be shaken or vibrated, resulting in some silicon powder with smaller particle size remaining on the filter screen and eventually being separated into silicon powder with larger particle size, resulting in poor separation effect.
[0006] To achieve the above objectives, this utility model provides a feeding structure for a silicon metal grinding device, including a base and a coarse screen feeding mechanism. The coarse screen feeding mechanism includes a mounting frame, a feeding box, a coarse screen box, a speed regulating component, a feeding channel, a vibration component, and a disassembly / assembly component. The mounting frame is fixedly connected to the top of the base, the feeding box is fixedly connected to the mounting frame, the coarse screen box is slidably connected to the feeding box, the speed regulating component is located above the mounting frame, the feeding channel is located above the speed regulating component, the vibration component is located inside the feeding box, and the disassembly / assembly component is located above the feeding box.
[0007] The speed control assembly includes a speed control motor, a rotating component, and a connecting plate. The speed control motor is fixedly connected to the top of the mounting bracket, the rotating component is disposed at the output end of the speed control motor, and the connecting plate is disposed above the rotating component.
[0008] The rotating component includes a rotating frame, a rotating shaft, and a connecting block. The rotating frame is fixedly connected to the top of the mounting frame. The rotating shaft is rotatably connected to the rotating frame and fixedly connected to the output end of the speed-regulating motor. The connecting block is fixedly connected between the rotating shaft and the connecting plate.
[0009] The vibration assembly includes a mounting frame and two miniature vibration motors. The mounting frame is fixedly connected to the feeding frame and located below the coarse screen box. The two miniature vibration motors are fixedly connected to the mounting frame and located on the surface of the coarse screen box.
[0010] The assembly / disassembly component includes a fixed frame, multiple threaded posts, and multiple nuts. The fixed frame is fixedly connected to the top of the coarse screen box, the multiple threaded posts are fixedly connected to the top of the feed box and pass through the fixed frame, and the multiple nuts are threadedly connected to the multiple threaded posts and are located above the fixed frame.
[0011] This utility model discloses a feeding structure for a silicon metal grinding device. Before use, a coarse screen box with a suitable aperture is selected and fixed using the disassembly and assembly components. During feeding, the speed control component is activated to adjust the inclination of the feeding channel, thereby controlling the feeding speed of the silicon powder. The top of the feeding channel is positioned at the output end of the grinding device. The silicon powder enters the coarse screen box along the feeding channel. The vibration component is activated to vibrate the coarse screen box, ensuring that silicon powder of suitable particle size passes through the coarse screen box and is discharged from the feeding box. Finally, the disassembly and assembly components are opened to remove the coarse screen box. This process handles silicon powder with larger particle sizes, avoiding the problem in existing silicon metal powder feeding devices where the filter screen cannot be shaken or vibrated, resulting in some smaller silicon powder remaining on the filter screen and being separated into larger silicon powder, leading to poor separation efficiency. This design improves the efficiency of subsequent screening. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] This utility model provides a feeding structure for a silicon metal grinding device: it includes a base 1 and a coarse screen feeding mechanism. The coarse screen feeding mechanism includes a mounting frame 2, a feeding box 3, a coarse screen box 4, a speed regulating component 5, a feeding channel 6, a vibration component 7, and a disassembly and assembly component 8. The speed regulating component 5 includes a speed regulating motor 9, a rotating component 10, and a connecting plate 11. The rotating component 10 includes a rotating frame 12, a rotating shaft 13, and a connecting block 14. The vibration component 7 includes a mounting frame 15 and two micro vibration motors 16. The disassembly and assembly component 8 includes a fixing frame 17, multiple threaded columns 18, and multiple nuts 19. The aforementioned solution solves the problem that in existing silicon metal powder feeding devices, the filter screen cannot be shaken or vibrated, resulting in some smaller silicon powder particles remaining on the filter screen and eventually being separated into larger silicon powder particles, leading to poor separation effect.
[0021] In this specific embodiment, the mounting frame 2 is fixedly connected to the top of the base 1, the feeding box 3 is fixedly connected inside the mounting frame 2, the coarse screening box 4 is slidably connected inside the feeding box 3, the speed regulating component 5 is disposed above the mounting frame 2, the feeding channel 6 is disposed above the speed regulating component 5, the vibration component 7 is disposed inside the feeding box 3, and the disassembly / assembly component 8 is disposed above the feeding box 3. Before use, a coarse screening box 4 with a suitable aperture is selected as needed, and the disassembly / assembly component 8 is used to disassemble / assemble the coarse screening box 4. When the assembly 8 is fixed, the speed control assembly 5 is activated as needed during feeding to adjust the inclination of the feeding channel 6, thereby controlling the feeding speed of silicon powder. The top of the feeding channel 6 is positioned at the output end of the grinding device. The silicon powder enters the coarse sieve box 4 along the feeding channel 6. The vibration assembly 7 is activated to make the coarse sieve box 4 vibrate, so that silicon powder of suitable particle size passes through the coarse sieve box 4 and is discharged from the feeding box 3. Finally, the disassembly assembly 8 is opened to remove the coarse sieve box 4 to process silicon powder with larger particle size.
[0022] The speed-regulating motor 9 is fixedly connected above the mounting bracket 2, the rotating component 10 is disposed at the output end of the speed-regulating motor 9, and the connecting plate 11 is disposed above the rotating component 10. When the debugging component is used, the speed-regulating motor 9 is started, and the connecting plate 11 is flipped under the action of the rotating component 10, thereby adjusting the inclination of the discharge channel 6.
[0023] Secondly, the rotating frame 12 is fixedly connected to the top of the mounting frame 2, the rotating shaft 13 is rotatably connected to the rotating frame 12 and fixedly connected to the output end of the speed-regulating motor 9, and the connecting block 14 is fixedly connected between the rotating shaft 13 and the connecting plate 11. When the speed-regulating motor 9 starts, the rotating shaft 13 rotates under the stability of the rotating frame 12, and drives the connecting plate 11 to flip through the connecting block 14.
[0024] Meanwhile, the mounting frame 15 is fixedly connected to the feeding frame and located below the coarse sieve box 4. The two micro vibration motors 16 are fixedly connected to the mounting frame 15 and located on the surface of the coarse sieve box 4. The model of the micro vibration motors 16 is HFF-130PA (vibration). When using the vibration assembly 7, the two micro vibration motors 16 are started to vibrate the coarse sieve box 4, causing it to shake, so that all the silicon powder with the appropriate particle size in it passes through the coarse sieve box 4.
[0025] Finally, the fixing frame 17 is fixedly connected to the top of the coarse screen box 4, and the plurality of threaded posts 18 are fixedly connected to the top of the feed box 3 and pass through the fixing frame 17. The plurality of nuts 19 are respectively threadedly connected to the plurality of threaded posts 18 and are located above the fixing frame 17. When the coarse screen box 4 is taken out, the plurality of nuts 19 are unscrewed, and then the coarse screen box 4 is lifted to separate it from the plurality of threaded posts 18.
[0026] Before use, select a coarse sieve box 4 with a suitable aperture as needed and fix it with the disassembly and assembly component 8. During feeding, activate the speed regulating component 5 as needed to adjust the inclination of the feeding channel 6, thereby controlling the feeding speed of silicon powder. Position the top of the feeding channel 6 at the output end of the grinding device. The silicon powder enters the coarse sieve box 4 along the feeding channel 6. Activate the vibration component 7 to vibrate the coarse sieve box 4, ensuring that silicon powder of suitable particle size passes through the coarse sieve box 4 and is discharged from the feeding box 3. Finally, open the disassembly and assembly component 8 to remove the coarse sieve box 4 to process silicon powder with larger particle sizes. When using the adjustment component, activate the speed regulating motor 9. Under the action of the rotating component 10, the connecting plate 11 flips, thereby adjusting the inclination of the feeding channel 6. When the speed-regulating motor 9 starts, the rotating shaft 13 rotates under the stability of the rotating frame 12, and drives the connecting plate 11 to flip through the connecting block 14. When using the vibration assembly 7, the two micro vibration motors 16 are started to vibrate the coarse screen box 4, causing it to shake, so that all the silicon powder with the appropriate particle size in it passes through the coarse screen box 4. When removing the coarse screen box 4, the multiple nuts 19 are unscrewed, and then the coarse screen box 4 is lifted to separate it from the multiple threaded columns 18. This avoids the problem that the filter screen of the existing metal silicon powder feeding device cannot shake or vibrate, and some silicon powder with a smaller particle size will remain on the filter screen and eventually be separated into silicon powder with a larger particle size, resulting in poor separation effect. This improves the efficiency of subsequent screening.
