[0016] A method for using a raw material crushing device for purifying metallic silicon comprises the following steps:

[0018] Step 2: The particles are discharged from the discharge box and roll down along the inclined surface of the inner wall of the discharge box to complete the crushing and discharge process;

The opening and closing plates on both sides are hinged and descended by the connecting rods and the rotating balls on both sides, thereby opening the area originally closed by the two opening and closing plates. At this time, the crushed particles of the raw materials accumulated between each convex strip naturally fall down, and the particles falling between the two convex strips will also be isolated by the two corresponding separation plates below the containing plate, thereby realizing different packaging of particles of different sizes through the containing container below.

[0023] 3. The present invention provides an auxiliary mechanism so that the dust generated by the friction between the broken particles when they fall can be carried away by the downward airflow, thereby avoiding the problem of a large amount of dust splashing above the containing plate when the material is dropped into the container.

[0024] 4. The present invention provides an auxiliary mechanism to fully break up the gravel particles in the material by rotating the blades, thereby avoiding the problem of gravel sticking to each other and piling up, and improving the filling and paving effect of the gravel evenly falling into the container below.

DETAILED DESCRIPTION

[0039] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a raw material crushing device for purifying metallic silicon, comprising a crusher 2, an inlet 1 is provided on the inner wall of the crusher 2, a discharge box 5 is fixedly connected to the bottom of the crusher 2, and a particle screening mechanism 3 is provided at the bottom of the discharge box 5;

[0040] The particle screening mechanism 3 comprises:

[0041] The holding plate 301 is a square plate-shaped structure. One side of the holding plate 301 is fixedly connected to one side of the discharge box 5. A convex strip 303 is fixedly connected to the top of the holding plate 301. Baffles 302 are fixedly connected to both sides of the top of the holding plate 301. The baffles 302 are rectangular plate-shaped structures, and the convex strips 303 are semicircular strip structures.

[0042] The separation plate 304 is a square plate structure. The top of the separation plate 304 is fixedly connected to the bottom of the holding plate 301. The inner wall of the holding plate 301 is hinged with an opening and closing plate 315. The bottom of the opening and closing plate 315 is rotatably connected to a rotating ball 314. The outer wall of the rotating ball 314 is fixedly connected to a connecting rod 313. The connecting rod 313 is an L-shaped rod structure. The separation plate 304 is used for separation when the crushed silicon blocks are discharged. When in use, the metal silicon blocks to be crushed are put into the inlet 1, and then the silicon blocks are crushed by the crusher inside the crusher 2. The crushed silicon blocks fall naturally and are discharged through the discharge box 5, and roll down along the inclined surface of the inner wall of the discharge box 5 to complete the crushing and discharge.

[0043] Example 2: Please refer to Figure 1-9 On the basis of the first embodiment, the present invention provides a technical solution: one end of the connecting rod 313 is fixedly connected to the telescopic rod 312 , and one end of the telescopic rod 312 is slidably connected to the sliding ring 311 .

[0044] The inner wall of the sliding ring 311 is fixedly connected with the internal thread sleeve 310 , the inner wall of the internal thread sleeve 310 is rotatably connected with the lifting slider 309 , and the inner wall of the lifting slider 309 is slidably connected with the outer wall of the threaded rod 307 .

[0045] The inner wall of the threaded rod 307 is slidably connected to the lifting rod 308, and the outer wall of the lifting rod 308 is slidably connected to the inner wall of the lifting slider 309 through a slider.

[0046] A connecting plate 305 is fixedly connected to one side of the separation plate 304, a pressing plate 316 is fixedly connected to the bottom end of the lifting rod 308, a pulling plate 317 is fixedly connected to the outer wall of the pressing plate 316, and the pressing plate 316 is slidably connected to the inner wall of the separation plate 304;

[0047] The crushed raw material fragments roll down under the action of gravity, roll onto the holding plate 301, and are collected on the holding plate 301. As the crushed raw material fragments of different sizes fall, the gravitational potential energy is different. When the smaller raw material fragments pass through the convex strips 303 on the holding plate 301, they are easily blocked, reducing the distance they roll forward on the holding plate 301. The gravitational potential energy of the larger fragments is greater, so they can roll farther on the holding plate 301 when blocked and decelerated by the baffle 302, thereby achieving a natural separation effect on the crushed silicon blocks of different sizes when unloading. The silicon blocks of different sizes are separated to different positions by themselves, which is convenient for the staff to collect and sort them together and carry out corresponding subsequent processing work on the fragments of different sizes.

[0048] The lifting block 309 is then pulled down by pulling the pressure plate 316. When the pressure plate 316 is lowered, the lifting rod 308 is driven to lower synchronously. When the lifting rod 308 is lowered, it will slide down on the inner wall of the threaded rod 307, and pull the lifting block 309 on the outer wall of the lifting rod 308 through the slider on the outer side of the top end of the lifting rod 308, and slide down on the outer wall of the threaded rod 307. The slider on one side of the top end of the lifting rod 308 is connected with the inner wall of the lifting block 309. The slider slides in the sliding groove opened on the outer wall of the threaded rod 307, so that it can pass through the threaded rod 307 and connect with the lifting block 309 on the outer wall of the threaded rod 307. When the pressure plate 316 is pulled down, the lifting rod 308 and the lifting block 309 are driven to descend synchronously. The lifting block 309 slides on the outer wall of the threaded rod 307 and rises vertically through the slider, and drives the internal threaded sleeve 310 to descend synchronously. The inner wall of the internal threaded sleeve 310 is rotatably connected with the outer wall of the lifting block 309, and is carried out. When the telescopic rod 312 is lowered, the outer wall of the internal threaded sleeve 310 is slidably connected with one end of the telescopic rod 312 through the sliding ring 311, thereby pulling the telescopic rod 312 down synchronously. When the telescopic rod 312 is lowered, the connecting rod 313 and the rotating ball 314 are lowered together, and the rotating ball 314 is connected to the bottom of the upper opening and closing plate 315 by rotation, so that the opening and closing plate 315 is pulled to be hinged and rotated and lowered. The opening and closing plates 315 on both sides are pulled and hingedly lowered by the connecting rods 313 and the rotating balls 314 on both sides, thereby opening the area originally closed by the two opening and closing plates 315. At this time, the crushed particles of the raw materials accumulated between each convex strip 303 naturally fall down, and the particles falling between the two convex strips 303 will also be isolated by the two corresponding separation plates 304 below the containing plate 301, so that particles of different sizes can be packaged differently through the containing container below.

[0049] Example 3: Please refer to Figure 1-13 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: an auxiliary mechanism 4 is provided on the outer wall of the internal threaded sleeve 310, the auxiliary mechanism 4 includes a blade 401, one end of the blade 401 is fixedly connected to the outer wall of the internal threaded sleeve 310, and a thread groove 402 is provided on the outer wall of the threaded rod 307.

[0050] One end of the connecting plate 305 is fixedly connected to a fixing sleeve 404, the top of the fixing sleeve 404 is fixedly connected to a spring 403, one end of the spring 403 is rotatably connected to the bottom of the internal threaded sleeve 310 through a bearing, the outer wall of the threaded rod 307 is threadedly connected to the inner wall of the internal threaded sleeve 310 through a threaded groove 402, and the inner wall of the fixing sleeve 404 is fixedly connected to the outer wall of the threaded rod 307.

[0051] At the same time, during the process of the internal threaded sleeve 310 descending, it will start to rotate through the threaded connection between the inner wall and the threaded groove 402 on the outer wall of the threaded rod 307. Since the thread lead angle of the threaded groove 402 is large, the friction force is small, and it is easier to rotate for vertical lifting, thereby driving the blades 401 on the outer wall to rotate synchronously. The rotation of the blades 401 will fan the air and draw the air above downward, so that the dust generated by the friction between the broken particles when they fall will be taken away together through the downward airflow, avoiding the problem of a large amount of dust splashing above the holding plate 301 when the material is discharged into the container. In addition, the rotation of the blades 401 can fully break up the crushed stone particles in the discharged material, avoiding the problem of crushed stones sticking to each other and piling up, thereby improving the filling and paving effect of the crushed stones falling evenly in the container below.

[0052] When the internal thread sleeve 310 descends, it will be rotatably connected to the top of the spring 403 through the bearing at the bottom, so that the spring 403 will be pressed and deformed when descending;

[0053] A method for using a raw material crushing device for purifying metallic silicon comprises the following steps:

[0054] Step 1: When in use, put the metal silicon block to be crushed into the inlet 1, and then the crusher inside the crusher 2 crushes the silicon block, and the crushed silicon block falls naturally.

[0055] Step 2: The particles are discharged through the discharge box 5 and roll down along the inclined surface of the inner wall of the discharge box 5 to complete the crushing and discharge function;

[0056] Step 3: The crushed raw material fragments roll down under the action of gravity and fall onto the holding plate 301, where they are collected;

[0057] The above description is only a preferred specific implementation manner 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 scheme and inventive concept 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.
