Description

Technical Field

[0001] This utility model relates to the technical field of silicon powder preparation, and specifically to a crushing device for preparing fine silicon powder. Background Technology

[0002] Microsilica, also known as silica fume or condensed silica fume, is formed when a large amount of highly volatile SiO2 and Si gas is produced in a submerged arc furnace during the smelting of ferrosilicon and industrial silicon (metallic silicon). After the gas is released, it is rapidly oxidized, condensed, and precipitated by air.

[0003] Currently, most methods for processing silicon powder are pulverization, which is carried out by pulverizers. However, most of the pulverizers currently in use have simple structures and can only perform single-pass pulverization through the pulverizing rollers, resulting in poor pulverization effect. In addition, after pulverization, the existing crushing devices cannot simultaneously adsorb and clean the residual metal impurities in the silicon powder.

[0004] Therefore, this utility model proposes a crushing device for preparing fine silicon powder. Utility Model Content

[0006] The existing crushing device can only perform single-pass crushing through the crushing roller, resulting in poor crushing effect. Furthermore, after crushing, the existing crushing device cannot simultaneously adsorb and clean the residual metal impurities in the silicon powder.

[0007] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

A buffer spring is fixedly connected between the mounting seat and the connecting plate.

[0009] The dispersion assembly includes a dispersion cylinder and a dispersion plate on its inner surface.

[0010] Furthermore, the guide platform is a trapezoidal platform with two sets horizontally arranged and opposite each other. The top surface of the guide platform is provided with a transverse sliding groove corresponding to the guide frame.

[0011] Furthermore, the connecting plate is arranged in an "L" shape, with its top bend section and the inner end of the guide frame connected in an outward tilt. The crushing liner is arranged vertically along the surface of the connecting plate, and its surface is arranged in a corrugated convex shape.

[0012] Furthermore, two sets of hydraulic rods are horizontally arranged, and their outer ends are simultaneously fixedly connected to the inner wall of the crushing body.

[0013] Furthermore, the mounting bases are arranged in a trapezoidal shape with opposite sides, the buffer springs are arranged horizontally, and the upper section of the mounting bases and the bottom outer side of the connecting plate are connected. There are two sets of crushing rollers distributed opposite each other, located between the two sets of mounting bases, while the discharge chamber is vertically opened directly below the crushing rollers.

[0014] Furthermore, the dispersion cylinder is arranged in an "L" shape, with its top section being trapezoidal and its bottom section being horizontal.

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] See Figure 1-5 As shown, a crushing device for preparing fine silicon powder includes a crushing body 1, a dispersing component 2, and a guiding mechanism 3. The guiding mechanism 3 is horizontally embedded in the dispersing component 2. The top and bottom of the crushing body 1 are respectively fixedly provided with an inlet hood 4 and an outlet chamber 5. The crushing body 1 has guide platforms 6 embedded on both sides. The top of the guide platform 6 is movably connected to a guide frame 10. The inner end of the guide frame 10 is fixedly connected to a connecting plate 7. The inner surface of the connecting plate 7 is fixedly connected to a crushing liner 8. The outer surface of the connecting plate 7 is fixedly connected to a hydraulic rod 9. The lower sides of the interior of the crushing body 1 are fixedly connected to a mounting base 11 and a mounting support 12. The inner side of the mounting support 12 is embedded with a crushing roller 13. A buffer spring 14 is fixedly connected between the mounting base 11 and the connecting plate 7. The dispersing component 2 includes a dispersing cylinder 15 and a dispersing plate 16 on its inner surface.

[0030] In this embodiment of the utility model, the guide platform 6 is a trapezoidal platform with two sets arranged horizontally and distributed opposite each other. The top surface of the guide platform 6 is provided with a horizontal sliding groove corresponding to the guide frame 10. The guide frame 10 is L-shaped, and its outer corner end is simultaneously slidably embedded in the sliding groove on the surface of the guide platform 6. The connecting plate 7 is L-shaped, and its top corner section is inclined outward to the inner end of the guide frame 10. The crushing liner 8 is vertically arranged along the surface of the connecting plate 7, and its surface is corrugated and raised. Two sets of hydraulic rods 9 are arranged horizontally, and their outer ends are simultaneously fixedly connected to the inner wall of the crushing body 1. The guide platform 6 facilitates the horizontal sliding adjustment of the guide frame 10 along its surface. The guide frame 10 provides adjustment guidance for the connecting plate 7. The hydraulic rods 9 control the inward and outward movement adjustment of the connecting plate 7. The connecting plate 7, in conjunction with the crushing liner 8 on its surface, crushes and grinds the silicon block entering the crushing body 1.

[0031] After the external silicon block is fed into the crushing body 1 through the feed hood 4, the hydraulic rod 9 is activated to drive the connecting plate 7 to move inward and outward within the crushing body 1. At the same time, the guide frame 10 slides along the guide table 6 to ensure the stability of the movement adjustment of the connecting plate 7. During this period, the crushing liner 8 performs preliminary crushing and grinding of the silicon block. When the external silicon block is fed into the crushing body 1, it is concentrated at the top corner of the connecting plate 7. As the connecting plate 7 moves inward and outward, it adjusts the gap and enters the crushing liner 8 for crushing.

[0032] The mounting bases 11 are arranged in a trapezoidal shape with opposite sides. The buffer springs 14 are horizontally arranged and connect the upper section of the mounting bases 11 and the bottom outer side of the connecting plate 7. Two sets of crushing rollers 13 are distributed opposite each other and located between the two sets of mounting bases 11. The discharge chamber 5 is vertically opened directly below the crushing rollers 13. The buffer springs 14 achieve the effect of buffering the internal and external movement adjustment of the connecting plate 7. The crushing rollers 13 achieve the effect of secondary crushing of the silicon block after initial crushing. The discharge chamber 5 achieves the effect of conveying and dispersing the crushed silicon powder in the component 2.

[0033] After being crushed by the crushing liner 8, the silicon blocks fall between the crushing rollers 13. The crushing rollers 13 rotate to perform secondary crushing, and finally the silicon blocks are directly guided into the dispersing cylinder 15 through the discharge chamber 5.

[0034] The dispersion cylinder 15 is generally L-shaped, with a trapezoidal top section and a horizontal bottom section. There are four sets of dispersion plates 16, each including a horizontal plate and a drive shaft in the center. The outer end of the drive shaft is equipped with a motor drive mechanism outside the dispersion cylinder 15. Magnetic lining plates are fixedly connected to the inner walls on both sides of the dispersion cylinder 15. The dispersion cylinder 15, in conjunction with the dispersion plates 16 on its inner surface, achieves the effect of dispersing the pulverized silicon powder. The magnetic lining plates on the inner walls on both sides of the dispersion cylinder 15 achieve the effect of adsorbing and cleaning metal impurities in the dispersed silicon powder.

[0035] After being pulverized twice by the crushing roller 13, the silicon powder is directly fed into the dispersing cylinder 15 through the discharge chamber 5. The dispersing plate 16 rotates to disperse the silicon powder. After dispersion, the metal impurities in the silicon powder are adsorbed and concentrated on the magnetic lining plate on the inner wall of the dispersing cylinder 15. The silicon powder enters the lower section of the dispersing cylinder 15 and is discharged outward through the material guiding mechanism 3.

[0036] The material guiding mechanism 3 of this device is set as a conveying auger mechanism, and the driving method of the crushing roller 13 is all existing publicly available technology. Its corresponding driving mechanism is directly installed in the mounting base 11. Its working principle and specific driving structure will not be described in detail here.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
