The block 306 moves toward the outside of the device under the pressure of the hook 304, and the spring 2 308 is deformed under the force. When one side of the bottom end of the hook 304 moves to the bottom of the block 306, the hook 304 is limited. This design prevents the molten silicon micropowder from being shaken out from the feed port during the screening process.

[0030] In one embodiment, the angle-adjustable screening assembly 2 includes a bottom frame 201, an L-shaped discharge port 202 is fixedly embedded inside the bottom frame 201, the bottom frame 201 is connected to the inside of the L-shaped discharge port 202, a U-shaped fixing hoop 203 is movably sleeved on the surface of the L-shaped discharge port 202, bolts 204 are movably embedded at both ends of the U-shaped fixing hoop 203, and a screening frame 205 is provided on the surface of the top of the bottom frame 201 through a bearing sleeve.

[0031] Specifically: the rotatable bottom frame 201 is fixed by means of a bolt 204 in cooperation with a U-shaped fixing hoop 203 to prevent the bottom frame 201 from rotating under the vibration of the vibration motor 105 during the screening process; the opening diameters at both ends of the U-shaped fixing hoop 203 are smaller than the bolt head diameter of the bolt 204, so that the bolt 204 cooperates with the threaded hole 106 to fix the two ends of the U-shaped fixing hoop 203.

[0032] In one embodiment, an L-shaped discharge port 206 is fixedly embedded inside the screening frame 205, and the screening frame 205 is connected to the interior of the L-shaped discharge port 206. A U-shaped fixing hoop 207 is movably sleeved on the surface of the L-shaped discharge port 206, and bolts 208 are movably embedded at both ends of the U-shaped fixing hoop 207. A fixing groove 209 is provided on the surface of one side of the top of the screening frame 205, and a movable groove 210 is provided through one side of the inner cavity of the fixing groove 209.

[0033] Specifically: the rotatable screening frame 205 is fixed by the second bolt 208 in cooperation with the second U-shaped fixing hoop 207 to avoid the situation in which the screening frame 205 rotates under the vibration of the vibration motor 105 during the screening process; the opening diameter at both ends of the second U-shaped fixing hoop 207 is smaller than the bolt head diameter of the second bolt 208, so that the second bolt 208 and the threaded hole 106 can cooperate to fix the two ends of the U-shaped fixing hoop 207.

[0034] In one embodiment, the shielding assembly 3 includes a cover plate 301 and a connecting rod 305. Two rotating grooves 302 are opened on one side of the cover plate 301. Rotating column grooves 303 are opened on both sides of the two rotating grooves 302. The bottom of the other side of the cover plate 301 is fixedly connected with a hook 304, and the top of the other side of the cover plate 301 is fixedly connected with a handle 309. The internal parts of the four rotating column grooves 303 are movably sleeved on the surfaces of the two ends of the two rotating columns 213, and the surface of the hook 304 is movably embedded in the inside of the fixed groove 209.

[0035] Specifically, the rotating column slot 303 and the rotating column 213 cooperate to fix the rotation of the cover plate 301 to prevent the cover plate 301 from being separated from the device.

[0036] In one embodiment, one end of the connecting rod 305 is fixedly connected to a block 306, and the other end of the connecting rod 305 is fixedly connected to a pull rod 307. A spring 2 308 is movably sleeved on the surface of the connecting rod 305. One end of the spring 2 308 is fixedly connected to one side of the block 306. Both ends of one side of the block 306 are fixedly connected to a limiting rod 310. The other ends of the two limiting rods 310 are fixedly connected to both ends of one side of the pull rod 307. The bottom of the block 306 is attached to the surface of the side end of the hook 304.

[0037] Specifically, the pull rod 307 is of a circular design, which is convenient for users to pull the pull rod 307 . The diameters of the block 306 and the pull rod 307 are much larger than the diameter of the movable groove 210 , which limits the movement of the connecting rod 305 .

[0038] In one embodiment, the inner cavity at the bottom of the bottom frame 201 is sleeved on the surface of the connecting column 107 through a bearing, and the surface of one end of the two bolts 204 is threadedly embedded in the inside of the other two threaded holes 106.

[0039] Specifically, the threaded hole 106 is formed away from the installation position of the fixing plate 104 to avoid affecting the normal use of the vibration motor 105 .

[0040] In one embodiment, the surface of the connecting rod 305 is movably embedded in the movable groove 210, the surfaces of the two limiting rods 310 are movably embedded in the two limiting grooves 211, and one end of the spring 2 308 is fixedly connected to one side of the fixed groove 209.

[0041] Specifically, the limiting rod 310 cooperates with the limiting groove 211 so that the connecting rod 305 cannot rotate, thereby avoiding affecting the cooperation between the clamping block 306 and the hook 304 .

[0042] Working principle: Place the molten silicon powder production, processing and screening device in a suitable position and connect it to an external power supply device. The external power supply device is electrically connected to the vibration motor 105 and provides power. The external controller is electrically connected to the vibration motor 105 and controls it in a related manner. Use a wrench to unscrew the bolt 1 204 or the bolt 2 208 to remove the U-shaped fixing hoop 1 203 or the U-shaped fixing hoop 2 207, rotate the bottom frame 201 or the screening frame 205, and adjust the discharge of the L-shaped discharge port 1 202 or the L-shaped discharge port 2 206. After adjusting the position to the appropriate position, re-thread the bolt 204 or the bolt 208 through the two ends of the U-shaped fixing hoop 1 203 or the U-shaped fixing hoop 207 to fix the U-shaped fixing hoop 1 203 or the U-shaped fixing hoop 207. This design allows the device to adjust the position of the feed opening as needed, which increases its practicality. One hand pulls the pull rod 307, the block 306 moves to the outside of the device, the spring 2 308 is deformed under the force, and the hook 304 loses the restriction of the block 306. The other hand holds the handle 30 9. The cover plate 301 can be opened, and the molten silicon powder to be screened is put in from the top of the inner cavity of the screening frame 205, and the cover plate 301 is closed. The upper part of the cover plate 301 at one end of the hook 304 is pressed, and the hook 304 moves to the lower part of the inner cavity of the fixed groove 209. The block 306 is moved to the outside of the device by the pressure of the hook 304, and the spring 2 308 is deformed by the force. When one side of the bottom end of the hook 304 moves to the lower part of the block 306, the block 306 is not subject to the pressure of the hook 304 and is under the action of the elastic force of the spring 2 308. Restore the initial position, limit the hook 304, start the vibration motor 105 through the external controller, and the vibration motor 105 drives the device to vibrate. Under the action of the vibration of the vibration motor 105, the molten silicon micropowder above the screening mesh 214 that meets the size conditions passes through the screening mesh 214 to the inner cavity of the bottom frame 201 and comes out from the L-shaped discharge port 1 202, and the molten silicon micropowder that does not meet the conditions comes out from the L-shaped discharge port 2 206. This design prevents the molten silicon micropowder from being shaken out from the feed port during the screening process.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. 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 for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
