Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of silicon micropowder processing, and in particular to a pulverizing device for processing molten silicon micropowder. Background Technology
[0002] Fused silica powder is a high-purity silica powder. It is produced by melting natural quartz or quartz sand into a liquid state at high temperature, then rapidly cooling and solidifying it into an amorphous solid, followed by a series of processes. During the processing of fused silica powder, a pulverizing device is required to crush the silicon raw material.
[0003] Currently, when pulverizing silicon raw materials, to ensure that the pulverized silicon meets specific size requirements, a sieve is usually used immediately after pulverization to separate materials of different particle sizes. However, because the pulverized silicon raw material falls continuously onto the sieve, even if the sieve is equipped with a vibration mechanism, material accumulation may occur. This accumulation slows down the entire sieving process and reduces sieving efficiency. Utility Model Content

[0005] Therefore, the purpose of this utility model is to propose a molten silicon micro powder processing and pulverizing device that can intermittently feed the pulverized silicon raw material, avoid excessive material accumulation on the vibrating screening mechanism, and thus effectively improve screening efficiency.
[0006] To achieve the above objectives, this utility model proposes a pulverizing device for processing molten silicon micropowder, comprising a shell, a pulverizing mechanism, an intermittent feeding mechanism, a vibrating screening mechanism, and a collecting mechanism.

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0021] The following description, in conjunction with the accompanying drawings, describes the molten silicon micro powder processing and pulverizing apparatus of this utility model.
[0022] like Figures 1-4 As shown, the molten silicon micro powder processing and pulverizing device of this utility model embodiment may include a housing 10, a pulverizing mechanism 20, an intermittent feeding mechanism 30, a vibrating screening mechanism 40, and a collecting mechanism 50.
[0023] The housing 10 has a feed inlet 11 on its top surface, two guide plates 12 below the feed inlet 11, the guide plates 12 being connected to the side wall of the housing 10, and a door 14 on one side of the housing 10.
[0024] It should be noted that the guide plate 12 can guide the silicon raw material to fall into the gap between the crushing mechanisms 20, and the door 14 can be used to easily remove the crushed silicon powder.
[0025] The crushing mechanism 20 is located below the guide plate 12.
[0026] A guide frame 13 is provided below the crushing mechanism 20, and the guide frame 13 is connected to the inner wall of the housing 10.
[0027] The interval feeding mechanism 30 includes two fixed plates 31, two rotating plates 32, two connecting shafts 33, and a drive mechanism 34. The two fixed plates 31 are respectively connected to the two side walls of the housing 10. The rotating plates 32 are hinged to the fixed plates 31 through the connecting shafts 33. The rotating plates 32 are located below the guide frame 13. The drive mechanism 34 is located on one side of the housing 10 and is connected to the connecting shafts 33.
[0028] It should be noted that the rotating plate 32 can block the pulverized silicon powder and prevent continuous feeding. There is a gap between the two rotating plates 32 to allow the rotating plates 32 to move. The guide frame 13 can guide the silicon powder and prevent it from falling into the gap.
[0029] The drive mechanism 34 can drive the connecting shaft 33 and the rotating plate 32 to rotate, thereby feeding the crushed silicon powder. Intermittent feeding avoids excessive material accumulation on the vibrating screening mechanism 40, thus improving screening efficiency.
[0030] The vibrating screening mechanism 40 is located below the interval feeding mechanism 30.
[0031] The collection mechanism 50 is respectively installed on the bottom wall of the housing 10 and on one side of the housing 10.
[0032] Specifically, the staff first starts the crushing mechanism 20, then puts the silicon micro powder to be crushed into the feed inlet 11. The guide plate 12 can guide the silicon raw material to fall into the gap between the crushing mechanisms 20, and crush it through the crushing mechanism 20.
[0033] The pulverized silicon powder falls onto the rotating plate 32 via the guide frame 13. The drive mechanism 34 is activated, which drives the connecting shaft 33 and the rotating plate 32 to rotate, feeding the silicon powder onto the vibrating screen mechanism 40. Then the drive mechanism 34 drives the rotating plate 32 back to its original position for intermittent feeding.
[0034] The vibrating screening mechanism 40 screens the silicon micro powder, and then the collecting mechanism 50 collects the silicon micro powder that is larger than the sieve hole size and the silicon micro powder that is smaller than the sieve hole size respectively.
[0035] It can intermittently feed the crushed silicon raw materials, avoiding excessive material accumulation on the vibrating screen mechanism, thereby effectively improving the screening efficiency.
[0036] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the crushing mechanism 20 may include a first crushing roller 21, a second crushing roller 22 and two driving components 23. The first crushing roller 21 and the second crushing roller 22 are rotatably connected to the inner wall of the housing 10, and the two driving components 23 are respectively disposed on one side of the housing 10. The output ends of the two driving components 23 are respectively connected to the first crushing roller 21 and the second crushing roller 22.
[0037] It should be noted that the driving component 23 described in this embodiment can be a motor. The two driving components 23 can drive the first crushing roller 21 and the second crushing roller 22 to rotate respectively. The rotation directions of the first crushing roller 21 and the second crushing roller 22 are opposite.
[0038] In one embodiment of this utility model, such as Figure 3 As shown, the drive mechanism 34 may include an electric push rod 341, a movable plate 342, two racks 343 and two gears 344. The electric push rod 341 is connected to the housing 10, the movable plate 342 is connected to the piston end of the electric push rod 341, the two racks 343 are respectively connected to the movable plate 342, the two gears 344 mesh with the two racks 343 respectively, and the connecting shaft 33 passes through the housing 10 and is connected to the gears 344.
[0039] It should be noted that by controlling the extension and retraction of the piston end of the electric push rod 341, the moving plate 342 can be moved up and down, which in turn drives the rack 343 to move. Since the gear 344 meshes with the rack 343, the rack 343 will drive the gear 344 to rotate during its movement, thereby driving the connecting shaft 33 and the rotating plate 32 to rotate, so as to realize the unloading.
[0040] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the vibrating screening mechanism 40 may include a screening screen plate 41, a mounting frame 42, adjusting bolts 43, a clamping plate 44, a support plate 45, multiple springs 46, and a vibrating motor 47.
[0041] The screening screen plate 41 is inclined, and a through hole 15 is provided on one side of the housing 10. One end of the screening screen plate 41 is located in the mounting frame 42, and the other end is located in the through hole 15. The adjusting bolt 43 is threadedly connected to the mounting frame 42. The clamping plate 44 is rotatably connected to the adjusting bolt 43 and abuts against the screening screen plate 41. The support plate 45 is connected to the inner wall of the housing 10. Multiple springs 46 are respectively connected between the support plate 45 and the mounting frame 42. The vibration motor 47 is located on one side of the bottom surface of the screening screen plate 41.
[0042] It should be noted that the screening screen plate 41 can be clamped and fixed by the clamping plate 44 and the mounting bracket 42. When it is necessary to disassemble and maintain the screening screen plate 41, open the door 14, turn the adjusting bolt 43, and move the clamping plate 44 to release the fixation of the screening screen plate 41, thereby disassembling the screening screen plate 41.
[0043] The vibration motor 47, in conjunction with the spring 46, can drive the screening screen plate 41 and the mounting frame 42 to vibrate, thereby screening the silicon micro powder. Silicon micro powder smaller than the size of the screen holes of the screening screen plate 41 passes through the screening screen plate 41, while silicon micro powder larger than the size of the screen holes of the screening screen plate 41 remains above the screening screen plate 41.
[0044] In one embodiment of this utility model, such as Figure 1 As shown, the collection mechanism 50 may include a first collection groove 51 and a second collection groove 52, wherein the first collection groove 51 is disposed on the bottom wall of the housing 10, and the second collection groove 52 is disposed on one side of the housing 10 and located below the through hole 15.
[0045] It should be noted that silicon micropowder smaller than the sieve hole size of the sieve plate 41 can be collected through the first collection tank 51. The first collection tank 51 can be taken out by opening the door 14, while silicon micropowder larger than the sieve hole size of the sieve plate 41 falls into the second collection tank 52 through the through hole 15.
[0046] In summary, the molten silicon micro powder processing and pulverizing device of this utility model can intermittently feed the pulverized silicon raw material, avoiding excessive material accumulation on the vibrating screening mechanism, thereby effectively improving the screening efficiency.
