[0002] Metallic silicon is also called crystalline silicon or industrial silicon. Its main use is as an additive for non-ferrous alloys. Metallic silicon is a product smelted from quartz and coke in an electric furnace. The content of the main component silicon is about 98% (in recent years, silicon content of 99.99% is also included in metallic silicon);

[0004] When metallic silicon is crushed, it is usually put into the feed port in large quantities. However, once a large quantity is put into the feed port, there will be a problem that the feed port is difficult to fall because there are too many metallic silicon pieces and they are stuck in the feed port due to friction. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a metal silicon pulverizing mill feeding device and an operating method, which achieves the purpose of solving the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A metal silicon pulverizing mill feeding device comprises a pulverizer, a feed box is fixedly connected to the top of the pulverizer, and a stable feed mechanism is arranged inside the feed box;

[0007] The stable feeding mechanism comprises:

[0008] A fixed plate, the outer wall of which is fixedly connected to the inner wall of the feed box, a fixed cover is fixedly connected to the top of the fixed plate, a material discharge chute is provided on the inner wall of the fixed plate, and the fixed plate is a square frame structure, and the fixed plate is used to allow silicon blocks to fall from it;

[0009] A rectangular groove is provided in the inner wall of the fixed plate, a motor is fixedly connected to the inner wall of the rectangular groove, a rotating shaft is fixedly connected to the output end of the motor, a sprocket is fixedly connected to the outer wall of the rotating shaft, the outer wall of the sprocket is connected to another sprocket through transmission, the rectangular groove is used to place the sprocket, and the fixed cover is used to prevent the silicon block from touching the sprocket.

[0010] Preferably, the outer wall of the rotating shaft is fixedly connected with a toggle plate, the toggle plate is a square plate-shaped structure, and the inner wall of the toggle plate is rotatably connected with a rotating rod.

[0011] Preferably, an opening and closing plate is fixedly connected to the outer wall of the rotating rod, and the opening and closing plate is a square plate-shaped structure. A counterweight block is fixedly connected to the outer wall of the opening and closing plate, and the counterweight block is used to play a role of counterweight.

[0012] Preferably, a protrusion is fixedly connected to a side of the opening and closing plate away from the counterweight block, and a fixing rod is fixedly connected to an outer wall of the protrusion, and the fixing rod is a round rod-shaped structure.

[0013] Preferably, a blocking rod is fixedly connected to the outer wall of the toggle plate, the protrusion is located between the two blocking rods, and the protrusion is a square block structure.

[0014] According to the metal silicon crushing mill feeding device described in claim, the outer wall of the rotating shaft is provided with a speed-changing and stretching mechanism, and the speed-changing and stretching mechanism includes a fixed sleeve, and one side of the fixed sleeve is fixedly connected to the outer wall of the rotating shaft.

[0015] Preferably, the inner wall of the fixed sleeve is slidably connected to a sliding block, the inner wall of the fixed sleeve is fixedly connected to a built-in spring, and the other end of the built-in spring is fixedly connected to the outer wall of the sliding block.

[0016] A method for operating a metal silicon pulverizing mill feeding material comprises the following steps:

[0017] Step 1: When in use, put the metal silicon block into the feed box, and then start the crusher in the crusher to fully crush the metal silicon block that falls through the feed box;

[0018] Step 2: After breaking, the material is discharged, thus completing the crushing of the metal silicon block. When the metal silicon block is put into the feed box, the sprocket is controlled to rotate by starting the motor;

[0019] Step 3: When the sprocket rotates, it drives the transmission to another sprocket to rotate synchronously, so that each shaft rotates synchronously, and then continuously moves the silicon block and falls steadily.

[0020] The present invention provides a metal silicon pulverizing mill feeding device and an operating method, which have the following beneficial effects:

[0021] 1. The present invention provides a stable feeding mechanism. As the rotating shaft and the toggle plate rotate continuously, the silicon blocks are continuously toggled and stably dropped, thereby effectively achieving uniform and stable feeding of the silicon blocks when they fall. This prevents the metal silicon blocks from being stuck and difficult to fall due to friction during feeding, and breaks up the silicon blocks that adhere to each other, which is beneficial to subsequent crushing work.

[0022] 2. The present invention separates the silicon blocks by setting up a stable feeding mechanism, further reducing the problem of silicon blocks adhering to each other and blocking the falling of the blocks. When the toggle plates on both sides of the rotating shaft are kept in a horizontal state, there will still be an opening and closing plate on the inner wall of the toggle plate that will fall with gravity to open the space on the inner wall of the toggle plate, thereby completing the falling of the silicon blocks. Even if the toggle plate is constantly rotating, there can always be a stable opening for the silicon blocks to fall, so that the silicon blocks can fall stably and can be continuously toggled and separated to prevent squeezing and blockage.

[0023] 3. The present invention provides a stable feeding mechanism. The baffle bars on one side of the toggle plate can separate the silicon blocks when they pass through the inner wall of the toggle plate, thereby breaking up the silicon blocks that are attached together. At the same time, the opening and closing plate can also be supported, so that the opening and closing plate can only be opened and closed in one direction under the hinged rotation of the rotating rod. When opening and closing, the fixed rod is inserted into the silicon block pile to further separate the silicon blocks, and the silicon blocks are dropped through the baffle bars to complete efficient and stable silicon block feeding.

[0024] 4. The present invention provides a stable feeding mechanism. When the rotating shaft drives the toggle plate to rotate, the opening and closing plate and the protrusion flip and close and get stuck on the baffle rod. A protrusion with a raised side extends out from between the two baffle rods, and the baffle rod moves the silicon block to press down the silicon block stuck between the two baffle rods, thereby preventing blockage.

[0025] 5. The present invention sets a variable speed extension mechanism. When rapid feeding is required, the sliding block will extend the fixed sleeve to increase the area of ​​the silicon block. Then, the silicon block will no longer fall by gravity, but will be pushed down by the rapid movement of the fixed sleeve and the sliding block. Similarly, the opening and closing plate and the counterweight block are swung by the centrifugal force instead of opening and closing by gravity. The space inside the moving plate is closed, and the silicon block is efficiently fed by moving the silicon block. When stable separation and feeding of the silicon blocks is required, the opening and closing plate on the inner wall of the moving plate and the gravity of the counterweight block are hinged and rotated at a low speed, and the silicon blocks are separated and broken up by the baffle rod to ensure subsequent stable crushing work. Then, in different working modes, the corresponding most effective measures are provided to ensure the desired work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a metal silicon pulverizing mill feeding device, comprising a pulverizer 1, a feed box 2 is fixedly connected to the top of the pulverizer 1, and a stable feed mechanism 3 is arranged inside the feed box 2;

[0039] The stable feeding mechanism 3 comprises:

[0040] A fixed plate 301, the outer wall of the fixed plate 301 is fixedly connected to the inner wall of the feed box 2, a fixed cover 302 is fixedly connected to the top of the fixed plate 301, a material discharge chute 303 is opened on the inner wall of the fixed plate 301, and the fixed plate 301 is a square frame structure, and the fixed plate 301 is used to play the role of allowing silicon blocks to fall from it;

[0041] A rectangular groove 304 is provided in the inner wall of the fixed plate 301. A motor 305 is fixedly connected to the inner wall of the rectangular groove 304. A rotating shaft 307 is fixedly connected to the output end of the motor 305. A sprocket 306 is fixedly connected to the outer wall of the rotating shaft 307. The outer wall of the sprocket 306 is connected to another sprocket 306 through 315. The rectangular groove 304 is used to place the sprocket 306. The fixed cover 302 is used to prevent the silicon block from touching the sprocket 306.

[0042] When in use, the metal silicon block is put into the feed box 2, and then the crusher in the crusher 1 is started, so that the metal silicon block falling down is fully crushed through the feed box 2, and then discharged out after crushing, thereby completing the crushing work of the metal silicon block;

[0043] Example 2: Please refer to Figure 1-9 On the basis of the first embodiment, the present invention provides a technical solution: the outer wall of the rotating shaft 307 is fixedly connected with a toggle plate 308, the toggle plate 308 is a square plate structure, and the inner wall of the toggle plate 308 is rotatably connected with a rotating rod 309.

[0044] An opening and closing plate 310 is fixedly connected to the outer wall of the rotating rod 309. The opening and closing plate 310 is a square plate structure. A counterweight block 314 is fixedly connected to the outer wall of the opening and closing plate 310. The counterweight block 314 is used to play a role of counterweight.

[0045] A protrusion 311 is fixedly connected to one side of the opening and closing plate 310 away from the counterweight block 314 , and a fixing rod 313 is fixedly connected to the outer wall of the protrusion 311 . The fixing rod 313 is a round rod-shaped structure.

[0046] The outer wall of the toggle plate 308 is fixedly connected with a blocking rod 312, and the protrusion 311 is located between the two blocking rods 312, and the protrusion 311 is a square block structure;

[0047] When the metal silicon block is put into the feed box 2, the sprocket 306 is controlled to rotate by starting the motor 305. When the sprocket 306 rotates, it drives 315 to transmit to another sprocket 306 to rotate synchronously, so that each shaft 307 rotates synchronously. When the shaft 307 rotates, it drives the toggle plate 308 on the outer wall to rotate. When the toggle plate 308 rotates, the space of the feed chute 303 in the fixed plate 301 is opened, so that the silicon block will fall through the gap between each shaft 307, and with the continuous rotation of the shaft 307 and the toggle plate 308, the silicon block is continuously toggled and falls steadily, effectively realizing the uniform and stable feeding of the silicon block when it falls, preventing the metal silicon block from being squeezed and stuck due to friction during feeding and being difficult to fall, and breaking up the silicon blocks that adhere to each other, which is beneficial to the subsequent crushing work;

[0048] When the rotation of the shaft 307 drives the toggle plate 308 to rotate synchronously, the opening and closing plate 310 on the inner wall of the toggle plate 308 starts to drive the rotating rod 309 to rotate synchronously with the rotation, and the opening and closing plate 310 rotates in the inner wall of the toggle plate 308 through the rotating rod 309, thereby opening the space on the inner wall of the toggle plate 308. When the toggle plate 308 toggles the silicon block, not only the silicon block falls through the gap between the shafts 307 and the shafts 307, but also the silicon block can be toggled through the open space on the inner wall of the toggle plate 308, so that the silicon block is quickly toggled, so that the silicon block is separated. The problem of silicon blocks being stuck and unable to fall due to adhesion to each other is further reduced. When the toggle plates 308 on both sides of the rotating shaft 307 are kept in a horizontal state, there will still be an opening and closing plate 310 on the inner wall of the toggle plate 308 that will fall with gravity to open the space on the inner wall of the toggle plate 308, thereby completing the work of the silicon block falling at this time. Even if the toggle plate 308 is constantly rotating, there can always be a stable opening for the silicon block to fall, so that the silicon block can fall stably and can be separated by continuous toggle, preventing the block from being squeezed and blocked.

[0049] At the same time, the blocking rods 312 on one side of the toggle plate 308 will separate the silicon blocks when they pass through the inner wall of the toggle plate 308, breaking up the silicon blocks that are attached together, and at the same time, the opening and closing plate 310 can be supported, so that the opening and closing plate 310 can only be opened and closed in one direction under the hinged rotation of the rotating rod 309, and when opening and closing, the fixed rod 313 is inserted into the silicon block pile to further separate the silicon blocks, and the silicon blocks fall through the blocking rods 312, completing the efficient and stable silicon block feeding work;

[0050] As the rotating shaft 307 drives the toggle plate 308 to rotate, when the opening and closing plate 310 and the protrusion 311 are turned over and closed and stuck on the blocking rod 312, the protrusion 311 protrudes from one side and extends out between the two blocking rods 312, and the blocking rod 312 moves the silicon block, and the silicon block stuck between the two blocking rods 312 is pressed down to prevent the blockage problem;

[0051] Example 3: Please refer to Figure 1-11 On the basis of the first and second embodiments, the present invention provides a technical solution: a speed-changing and stretching mechanism 4 is provided on the outer wall of the rotating shaft 307 , and the speed-changing and stretching mechanism 4 includes a fixed sleeve 401 , and one side of the fixed sleeve 401 is fixedly connected to the outer wall of the rotating shaft 307 .

[0052] The inner wall of the fixing sleeve 401 is slidably connected to a sliding block 402 . The inner wall of the fixing sleeve 401 is fixedly connected to a built-in spring, and the other end of the built-in spring is fixedly connected to the outer wall of the sliding block 402 .

[0053] When the rotating shaft 307 rotates at a slow speed, the weight of the opening and closing plate 310 and the counterweight block 314 is used to drive the rotating rod 309 to rotate in an articulated manner to realize opening and closing, so that the silicon block can fall stably and evenly through the gap inside the toggle plate 308. When the rotating shaft 307 rotates at a fast speed, it will swing the fixed sleeve 401 outward, and the centrifugal force exerted on the sliding block 402 will overcome the elastic force of the built-in spring between the sliding block 402 and the fixed sleeve 401, so that the sliding block 402 is thrown outward from the inner wall of the fixed sleeve 401. The faster the rotation speed, the longer the sliding block 402 is thrown out. Therefore, when fast feeding is required, the sliding block 402 will extend out of the fixed sleeve 401 to increase the area of ​​the toggle silicon block, and then the silicon block will no longer be used. The silicon block does not fall due to the gravity of the block itself, but uses the fast toggle of the fixed sleeve 401 and the sliding block 402 to push the silicon block downward. The opening and closing plate 310 and the counterweight block 314 are also thrown along with the centrifugal force and no longer open and close along with the gravity. The space inside the toggle plate 308 is closed, and the silicon block is efficiently fed by toggling the silicon block. When the silicon block needs to be stably separated and fed, the opening and closing plate 310 on the inner wall of the toggle plate 308 and the counterweight block 314 are hingedly opened and closed and rotated at a low speed, and the silicon block is separated and broken up by the blocking rod 312 to ensure the subsequent stable crushing work, and then in different working modes, the corresponding most effective measures are provided to ensure the desired work efficiency.

[0054] A method for operating a metal silicon pulverizing mill feeding material comprises the following steps:

[0055] Step 1: When in use, put the metal silicon block into the feed box 2, and then start the crusher in the crusher 1, so that the metal silicon block falling down is fully crushed through the feed box 2;

[0056] Step 2: After the metal silicon blocks are crushed, the materials are discharged, thereby completing the crushing work of the metal silicon blocks. When the metal silicon blocks are put into the feed box 2, the sprocket 306 is controlled to rotate by starting the motor 305;

[0057] Step 3: When the sprocket 306 rotates, it drives 315 to transmit to another sprocket 306 to rotate synchronously, so that each shaft 307 rotates synchronously, and then continuously moves the silicon block and stably falls.

[0058] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
