In the using process of the invention, when the metal silicon powder production raw materials are added into the feeding hopper for storage and the metal silicon powder production raw materials are required to be added into the crushing bin 201, the feeding valve 501 is opened, and the metal silicon powder production raw materials in the feeding hopper enter the crushing bin 201 through the feeding pipe 502.
When the controller detects that the feed valve 501 is opened, the controller controls the driving motor 307 to start to operate at a low speed, as the metal silicon powder production raw material enters the initial stage of the crushing bin 201, the metal silicon powder production raw material is not crushed but has a large particle size, and when the metal silicon powder production raw material with a large particle size is positioned between the crushing roller 203 and the grinding ring 204, if the crushing roller 203 rotates at a high speed, damage to the crushing roller 203 or the grinding ring 204 can be caused, therefore, at the initial stage of the metal silicon powder production raw material entering the crushing bin 201, the driving motor 307 running at a low speed drives the screening shaft 301 to rotate at a low speed, the screening shaft 301 rotates at a low speed through the magnetic coupling 302, the crushing roller 203 rotates at a low speed, the crushing roller 203 is matched with the grinding ring 204 to crush the metal silicon powder production raw material, and at the moment, the detection value of the pressure sensor 205 is the maximum, so that the crushing roller 203 and the grinding ring 204 of the equipment are protected while the crushing effect of the metal silicon powder production raw material is ensured, and the stability of the equipment is improved.
When the driving motor 307 runs at a low speed, the magnetic coupling 302 between the screening shaft 301 and the crushing shaft 202 does not need large magnetic force to keep stable transmission, at this time, the controller controls an independent power supply in the magnetic coupling 302 to output small current, the magnetic attraction force of the magnetic coupling 302 to the metal pull ring 304 is smaller than the tension force of the elastic screen 303 and the tension force of a torsion spring in the wind power assembly 6 while the stable transmission of the screening shaft 301 and the crushing shaft 202 is ensured, at this time, the aperture of the elastic screen 303 is minimum, and the wind power generated by the wind power assembly 6 is weakest, as the metal silicon powder raw materials enter the initial stage of the crushing bin 201, when the metal silicon powder raw materials are crushed and ground, dust in the metal silicon powder raw materials flies up first, and under the mutual cooperation of the wind power assembly 6 and the shovel blade 206, the upward wind force brings up dust, and because at this time, the aperture of the elastic screen 303 is minimum, dust can normally pass through the elastic screen 303 and is discharged from the discharge pipe 314, and the metal silicon powder raw materials cannot rise along with the wind force, so that the dust and other impurities in the metal silicon powder raw materials are primarily filtered, and the metal silicon powder raw materials are higher in production quality.
As the metal silicon powder production raw material is crushed and ground in the crushing bin 201, the grain size of the metal silicon powder is gradually reduced, the detection value of the pressure sensor 205 is also gradually reduced, when the detection value of the pressure sensor 205 is reduced to be lower than a first threshold value, the grain size of the metal silicon powder is indicated to reach the rough grinding requirement, at this time, the controller controls the rotation speed of the driving motor 307 to increase, and as the rotation speed of the driving motor 307 increases, the magnetic coupling 302 needs stronger magnetic force to ensure stable transmission between the screening shaft 301 and the crushing shaft 202, after detecting the rotation speed of the driving motor 307 increases, the controller correspondingly controls the output current of an independent power supply in the magnetic coupling 302 to increase, thereby increasing the magnetic force of the magnetic coupling 302, and the attraction force of the magnetic coupling 302 to the metal pull ring 304 is enhanced after the magnetic force of the magnetic coupling 302 is increased, so that the metal pull ring 304 moves downwards, the downward movement of the metal pull ring 304 stretches the elastic screen 303 through the connecting rope 305, so that the aperture of the elastic screen 303 is enlarged, the inclination angle of the fan blades 601 of the wind power assembly 6 is enlarged, the wind power generated by the wind power assembly 6 is enhanced, at the moment, with rough grinding of raw materials for producing metal silicon powder, dust with large particles in the raw materials is released, dust with the same particle size and metal silicon powder are lower in gravity than the metal silicon powder, the enlarged wind power flows upwards through the elastic screen 303 with the dust released by rough grinding, the elastic screen 303 is influenced by the tension of the metal pull ring 304, the diameter of the sieve holes of the elastic screen 303 is enlarged, therefore, the dust with large particles can be discharged from the discharge pipe 314 through the elastic screen 303, impurities are removed again for producing the metal silicon powder, the quality of the produced metal silicon powder is better, and after the rotation speed of the driving motor 307 is increased, the number of times of grinding the metal silicon powder in unit time is increased, so that the grain size of the metal silicon powder is smaller, no raw material with large grain size exists in the crushing bin 201, and the space between the crushing roller 203 with increased rotating speed and the grinding ring 204 is not damaged due to the influence of the raw material with large grain size.
When the detection value of the pressure sensor 205 is lower than the second threshold value, which indicates that the production of the metal silicon powder in the crushing bin 201 is completed, the controller controls the driving motor 307 to operate at the maximum power, and as the rotation speed of the driving motor 307 increases, the magnetic coupling 302 needs stronger magnetic force to ensure stable transmission between the screening shaft 301 and the crushing shaft 202, after detecting that the rotation speed of the driving motor 307 increases, the corresponding controller controls the output current of the independent power supply in the magnetic coupling 302 to increase, thereby increasing the magnetic force of the magnetic coupling 302, and the attraction force of the magnetic coupling 302 to the metal pull ring 304 is increased after the magnetic force of the magnetic coupling 302 increases, so that the metal pull ring 304 moves downwards, the metal pull ring 304 moves downwards to stretch the elastic screen 303 through the connecting rope 305, so that the aperture of the elastic screen 303 is maximized, the inclination angle of the fan blades 601 of the wind power assembly 6 is further increased, the wind power formed by the wind power assembly 6 is strongest, at the moment, the ground metal silicon powder passes through the elastic screen 303 and is discharged to a designated position through the discharge pipe 314 to be collected under the cooperation of the wind power generated by the wind power assembly 6 and the shovel blade 206, plant fibers such as branches and the like existing in the production raw materials in the crushing bin 201 are difficult to grind into powder, and therefore the plant fibers cannot pass through the elastic screen 303 and remain in the crushing bin 201, and the production quality of the equipment to the metal silicon powder is improved.
As the metal silicon powder in the crushing bin 201 is discharged, the detection value of the pressure sensor 205 gradually decreases to zero, and at this time, the controller controls the feed valve 501 to open, so that a new round of raw material adding grinding is performed in the crushing bin 201.
When the metal silicon powder is ground in the crushing bin 201, external air enters the sealing cover 308 through the air inlet hole 212, and due to rotation of the rotary table 207, the metal silicon powder in the middle position of the crushing bin 201 is blown to the peripheral shovel blades 206 by the air entering through the air inlet hole 212, so that the shovel blades 206 can be used for shoveling the metal silicon powder, and the convenience of equipment use is improved.
When the crushing shaft 202 cannot rotate due to the fact that the metal silicon powder with overlarge grain size is encountered between the crushing roller 203 and the grinding ring 204 when the metal silicon powder is ground in the crushing bin 201, the screening shaft 301 can continue to rotate due to the characteristics of the magnetic coupling 302, so that damage of the driving motor 307 is avoided, and the stability of equipment use is improved.
According to the invention, by arranging the magnetic coupling 302, the pressure sensor 205, the driving motor 307 and other devices, the pressure between the grinding ring 204 and the crushing bin 201 is detected by the pressure sensor 205, the crushing and grinding condition of the metal silicon powder raw materials in the crushing bin 201 is indirectly obtained, and the aperture change of the elastic screen 303 and the wind force formed by the wind power assembly 6 are controlled by controlling the rotation speed change of the driving motor 307, so that magazines such as dust in the metal silicon powder are removed and the metal silicon powder is discharged, and the production efficiency and the production quality of equipment on the metal silicon powder are improved.
The raw material crushing and screening equipment for producing the metal silicon powder is common in mechanical mode in the installation mode, the connection mode or the setting mode, and can be implemented as long as the beneficial effects of the equipment can be achieved.
