Technical Field

[0001] The utility model relates to the technical field of pulverizers, in particular to a cyclone pulverizer for silicon powder production. Background Art

[0002] Silica powder, also called microsilica powder, scientifically known as silica ash, is the smoke emitted with the exhaust gas during the high-temperature smelting of industrial silicon and ferrosilicon in industrial electric furnaces, and is collected and treated by a special capture device. In the emitted smoke, the SiO2 content accounts for about 90% of the total smoke, and the particle size is very small, with an average particle size of almost nanometer level, so it is called silicon powder. A cyclone crusher is required for the production of silicon powder.

[0003] In the prior art, such as Chinese patent announcement number: CN208583421U, a cyclone crusher for crushing silicon powder is disclosed, which includes a machine base, a driving mechanism connected to the machine base and a crushing mechanism connected to the driving mechanism; the crushing mechanism includes a cyclone shell, a rotating shaft arranged in the cyclone shell and connected to the driving mechanism, and a cyclone mechanism connected to the rotating shaft; the cyclone mechanism includes an upper cutter disc connected to the rotating shaft and a lower cutter disc located below the upper cutter disc, the upper cutter disc and the lower cutter disc are respectively provided with an upper cutter holder and a lower cutter holder evenly distributed in a circle, and the lower cutter holder is inclined; the upper cutter holder and the lower cutter holder are respectively installed with an upper blade and a lower blade; the device provides an evenly distributed staggered upper and lower cutter holders, while maintaining the lower cutter holder inclined, providing a cyclone field during operation, greatly increasing the residence time of the material, so that the blade has sufficient time to crush the material, increasing the output and reducing energy consumption.

[0004] Although the cyclone mill in the above patent improves the crushing effect and output of silicon powder by upgrading the single-layer cutter disc to an upper and lower double-layer cutter disc, the double-layer cyclone mill in the prior art can improve the crushing effect and output on the basis of the single-layer cutter disc by designing the cutter disc and the cutter holder, the rotation direction and frequency of the double-layer cutter disc are consistent, and the crushing effect and output of silicon powder are improved mainly by the impact crushing effect on both sides, and the practicality needs to be further improved. Therefore, in response to the above problems, we propose a new type of cyclone mill for silicon powder production. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the double-layer cyclone mill in the prior art can improve the crushing effect and output on the basis of the single-layer cutter disc by designing the cutter disc and the cutter holder, but the rotation direction and frequency of the double-layer cutter disc are consistent, and the crushing effect and output of silicon powder are improved mainly by the impact crushing effect on both sides, and the practicality needs to be further improved. A cyclone mill for silicon powder production is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cyclone mill for silicon powder production, comprising an outer shell, a plurality of first reinforcing ribs are fixedly connected to the outer surface of the outer shell at equal intervals, two feed ports are symmetrically arranged on the top of the outer shell, a lower connecting shell is fixedly connected to the top center of the outer shell, a plurality of second reinforcing ribs are fixedly connected to the outer surface of the lower connecting shell at equal intervals, an upper connecting shell is fixedly installed on the top of the lower connecting shell through a flange, a plurality of third reinforcing ribs are fixedly connected to the outer surface of the upper connecting shell at equal intervals, and a crushing assembly, which is arranged inside the outer shell.

[0007] Furthermore, a coupling is arranged inside the upper connecting shell, and a driving shaft is arranged inside the coupling.

[0008] Furthermore, a bearing is provided on the outer surface of the driving shaft, and the outer surface of the bearing is fixedly connected to the inner surface wall of the lower connecting shell.

[0009] Furthermore, the pulverizing assembly includes a pulverizing cutter disc and a gear sleeve, the top center of the pulverizing cutter disc is fixedly connected to the bottom end of the driving shaft, and a plurality of first pulverizing blades are fixedly connected to the top of the pulverizing cutter disc.

[0010] Furthermore, the top of the crushing cutter disc is equidistantly rotatably connected to a plurality of gear seats near the edge, the top of the gear seat is fixedly connected to a second crushing blade, and the bottom of the crushing cutter disc is equidistantly fixedly connected to a plurality of third crushing blades near the edge.

[0011] Furthermore, a plurality of connecting rods are equidistantly fixedly connected to the outer surface of the gear sleeve, the end faces of the connecting rods are fixedly connected to the inner surface wall of the outer shell, and the inner surface of the gear sleeve is meshingly connected to the outer surface of the gear seat.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when the crushing cutter disc rotates, it drives the four gear seats to rotate. When the gear seat rotates, the outer surface meshes with the inner wall of the gear sleeve, thereby rotating. The rotation direction is opposite to the rotation direction of the crushing cutter disc, and the rotation frequency is higher. At this time, the first crushing blade on the crushing cutter disc rotates at a high speed to impact and crush the raw material. At the same time, the gear seat moves while the second crushing blade on the top rotates in the opposite direction at a higher frequency. When the crushed raw material is impacted and thrown around to fall, the third crushing blade at the bottom of the crushing cutter disc crushes it again. The rotation directions and frequencies of multiple crushing blades are inconsistent, which improves the problem of consistent rotation direction and frequency of the double-layer cutter disc, thereby increasing the production output of silicon powder and further improving practicality.

[0014] 2. In the utility model, when the driving shaft rotates, a bearing is arranged on the outer surface to limit the driving shaft, thereby improving the stability during rotation and avoiding shaking. By arranging the first reinforcing rib, the second reinforcing rib and the third reinforcing rib, the firmness of the device is improved while reducing the weight and cost of the device.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1, as Figure 1-Figure 3As shown, the utility model provides a cyclone mill for silicon powder production, comprising an outer shell 1, a plurality of first reinforcing ribs 11 are equidistantly fixedly connected to the outer surface of the outer shell 1, two feed ports 12 are symmetrically arranged on the top of the outer shell 1, a lower connecting shell 2 is fixedly connected at the top center of the outer shell 1, a plurality of second reinforcing ribs 21 are equidistantly fixedly connected to the outer surface of the lower connecting shell 2, an upper connecting shell 22 is fixedly installed on the top of the lower connecting shell 2 through a flange, a plurality of third reinforcing ribs 23 are equidistantly fixedly connected to the outer surface of the upper connecting shell 22, and a crushing assembly 4 is arranged inside the outer shell 1, a coupling 31 is arranged inside the upper connecting shell 22, a driving shaft 3 is arranged inside the coupling 31, a bearing 32 is arranged on the outer surface of the driving shaft 3, and the outer surface of the bearing 32 is fixedly connected to the inner surface wall of the lower connecting shell 2.

[0022] The effect achieved by the entire embodiment 1 is that when the impact cyclone crusher in the device is in use, the top of the driving shaft 3 is connected to the power device, and the driving shaft 3 and the crushing assembly 4 are driven to rotate by the power device. The feed port 12 plays a role in adding silicon powder raw materials into the device. When the crushing blade 401 in the crushing assembly 4 rotates, it drives the four gear seats 403 to rotate. When the gear seat 403 rotates, the outer surface engages with the inner wall of the gear sleeve 406, thereby rotating, and the rotation direction is opposite to the rotation direction of the crushing blade 401, and the rotation frequency is higher. At this time, the first crushing blade 402 on the crushing blade 401 rotates at a high speed to impact and crush the raw material. At the same time, the gear seat 403 moves while the second crushing blade 404 at the top rotates in the opposite direction at a higher frequency. When the crushed raw material is impacted and thrown around to fall, the third crushing blade 405 at the bottom of the crushing blade 401 crushes it again. The rotation directions and rotation frequencies of the multiple crushing blades are inconsistent, which improves the problem of the consistency of the rotation direction and frequency of the double-layer blade, thereby improving the production output of silicon powder and further improving the practicality.

[0023] Embodiment 2, as Figure 1-Figure 3 As shown, the crushing assembly 4 includes a crushing blade 401 and a gear sleeve 406. The top center of the crushing blade 401 is fixedly connected to the bottom end of the driving shaft 3. A plurality of first crushing blades 402 are fixedly connected to the top of the crushing blade 401. A plurality of gear seats 403 are equidistantly rotatably connected to the top of the crushing blade 401 near the edge. A second crushing blade 404 is fixedly connected to the top of the gear seat 403. A plurality of third crushing blades 405 are fixedly connected to the bottom of the crushing blade 401 near the edge at an equal distance. A plurality of connecting rods 407 are fixedly connected to the outer surface of the gear sleeve 406 at an equal distance. The end face of the connecting rod 407 is fixedly connected to the inner surface wall of the outer shell 1. The inner surface of the gear sleeve 406 is meshedly connected to the outer surface of the gear seat 403.

[0024] The effect achieved by the entire embodiment 2 is that when the drive shaft 3 rotates, the bearing 32 is arranged on the outer surface to limit the drive shaft 3, thereby improving the stability during rotation and avoiding shaking. By arranging the first reinforcing rib 11, the second reinforcing rib 21 and the third reinforcing rib 23, the firmness of the device is improved while reducing the weight and cost of the device.

[0025] Working principle: When the impact cyclone mill in the device is in use, the top of the driving shaft 3 is connected to the power device, and the driving shaft 3 and the crushing assembly 4 are driven to rotate by the power device. The feed port 12 plays a role in adding silicon powder raw materials into the device. When the crushing blade 401 in the crushing assembly 4 rotates, it drives the four gear seats 403 to rotate. When the gear seat 403 rotates, the outer surface meshes with the inner wall of the gear sleeve 406, so that it rotates, and the rotation direction is opposite to the rotation direction of the crushing blade 401, and the rotation frequency is higher. At this time, the first crushing blade 402 on the crushing blade 401 rotates at a high speed to impact and crush the raw materials. At the same time, the gear seat 403 moves while the second crushing blade 404 on the top moves in the opposite direction. The crushed raw materials are hit and thrown around to fall, and the third crushing blade 405 at the bottom of the crushing disc 401 crushes them again. The rotation directions and rotation frequencies of multiple crushing blades are inconsistent, which improves the problem of consistent rotation direction and frequency of the double-layer disc, thereby increasing the production output of silicon powder and further improving the practicality. When the drive shaft 3 rotates, the bearing 32 is arranged on the outer surface to limit the drive shaft 3, thereby improving the stability during rotation and avoiding shaking. The first reinforcing rib 11, the second reinforcing rib 21 and the third reinforcing rib 23 are arranged to further reduce the weight and cost of the device and improve the firmness of the device.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
