The inlet end of the horizontal conveying line is connected to the outlet end of the water cooling system, and the top outlet end of the inclined conveying line is connected to the crushing system. The above patent document performs water quenching treatment on silicon rods. The silicon rods are subjected to high temperature above 500 degrees, and cracks are generated in the silicon rods through rapid high temperature and low temperature principles, thereby reducing dust and particles generated by physical impact or hammering of the silicon rods, reducing loss, and reducing the crushing loss rate of the silicon rods.

[0031] In the implementation of the embodiment, first, the operator needs to open the console 1, and then adjust the parameters inside the console 1 to control the specific parameters of the power source inside the crushing assembly 4 and the conveying source inside the conveying assembly 6. Then, the operator can combine the external feeding device with the device, so that the feeding device can continuously feed the polysilicon material to be crushed into the extrusion assembly 5. The power source inside the crushing assembly 4 will drive the extrusion assembly 5 to start when it starts, so that the components inside the extrusion assembly 5 can crush the polysilicon material to be crushed for the first time, so that the large pieces of polysilicon material are crushed into small pieces, and then crushed by the crushing assembly 4 for the second time. The crushed polysilicon material will be recycled and filtered along the connecting assembly 2 fixedly connected to the bottom end of the crushing assembly 4, and then collected in the separation assembly 1 3. The water filtered by the connecting assembly 2 will be extracted by the conveying assembly 6 and then discharged into the extrusion assembly 5, so as to absorb and cool the heat generated during the extrusion process.

[0032] Further, it should be noted that in the initial state, the device contains cooling water, and the height of the cooling water should not exceed the middle part of the crushing assembly 4, and should not be lower than the upper right part of the connecting box 23. The power source inside the conveying assembly 6 enters the inner cavity of the extrusion assembly 5 in an intermittent manner during the extraction process.

[0033] Further, the console 1 mentioned above is a very mature technical means in the prior art, and in this scheme, only its controllable function is used, and the specific working principle and internal components are not described in detail.

[0034] Further, by cooperating the crushing assembly 4 and the extrusion assembly 5, the raw material can be further crushed and screened, the particle size distribution of the polysilicon particles can be improved to be more uniform, which is helpful for the subsequent melting and crystallization process. Further, by cooperating the conveying assembly 6 with the water inside the separation assembly 1 3, the heat generated during the crushing or extrusion process can be effectively removed, so as to avoid overheating of the crushing wheel and reduce material deformation, adhesion or burning caused by high temperature.

[0035] Further, please refer to Figure 3 , Figure 4 and Figure 5As shown, the connecting assembly 2 includes four support columns 21, the upper end of each of the four support columns 21 is fixedly connected with the bottom end of the crushing assembly 4, the middle of the side where the right two support columns 21 are close to each other is fixedly connected with a connecting rod 22, the side close to each other of the two connecting rods 22 is fixedly connected with a connecting box 23, the inner cavity of the connecting box 23 is fixedly connected with an inclined filter plate 24, the extrusion assembly 5 includes a shell two 51, the right inner cavity of the shell two 51 is fixedly connected with an extrusion block one 52, the upper left inner cavity of the shell two 51 is fixedly connected with a baffle 54, the left inner cavity of the shell two 51 is rotatably connected with an extrusion block two 53, the lower left inner cavity of the shell two 51 is rotatably connected with a matching rod 55, the outer surface of the matching rod 55 is fixedly connected with an eccentric wheel 57, the rear of the matching rod 55 is fixedly connected with a transmission wheel 56, the conveying assembly 6 includes an input pipe 61, the bottom end of the input pipe 61 is fixedly connected with the upper end of the left side of the separation assembly one 3, the other end of the input pipe 61 is fixedly connected with a water pump 62, the output end of the water pump 62 is fixedly connected with an output pipe 63, the other end of the output pipe 63 is fixedly connected with a converging box 64, the upper end of the converging box 64 is fixedly connected with three drain pipes 65, and the three drain pipes 65 are communicated with the right inner cavity of the shell two 51.

[0036] Further, in the present embodiment, when the power source inside the crushing assembly 4 is started, the transmission wheel 56 will drive the matching rod 55 to rotate when the internal power source and the internal components drive the transmission wheel 56 to rotate, the matching rod 55 will drive the eccentric wheel 57 fixedly connected to the outer surface to rotate when the matching rod 55 rotates, so that the extrusion block two 53 can pressurize the polysilicon material when the eccentric wheel 57 rotates due to its eccentric setting, so that the larger block is crushed, and the crushed polysilicon material will be crushed again by the crushing assembly 4, so that the polysilicon material crushed twice will follow the cooling water into the inner cavity of the connecting box 23 and be blocked by the filter plate 24, and the water pump 62 will intermittently cool the extrusion block one 52, so that the shell two 51 can intermittently extract the right inner cavity of the extrusion block one 52, and when the extrusion block one 52 stops extracting water in the inner cavity of the connecting box 23, the polysilicon material attached to the surface of the filter plate 24 will fall into the separation assembly one 3 due to gravity, and then wait for the operator to collect.

[0037] Further, it should be noted that the extrusion block one 52 mentioned above is a very mature technical means in the prior art, and in this scheme, only its extraction function is used, and the working principle and internal components are not described in detail.

[0038] Further, by setting the filter plate 24 in the inner cavity of the connecting box 23, when the extrusion block 1 52 intermittently extracts the water in the connecting box 23 through the shell 2 51, the crushed polysilicon material can be given a certain power, avoiding the material from stagnating or staying in the box, so that the polysilicon material can finally fall into the separation assembly 1 3, and when the extrusion block 1 52 extracts the water in the inner cavity of the connecting box 23, the extrusion block 1 52 can be cooled through the drain pipe 65, avoiding the extrusion block 1 52 from accumulating due to high temperature, and shortening the service life of the equipment.

[0040] By setting the motor 43, when starting, the belt 44 wrapped with the output end can drive the transmission 45 to rotate, and when the transmission 45 rotates, the rear part will drive the gear 1 483 to rotate through the transmission belt 482, so that when the gear 1 483 rotates, the gear 2 484 will be driven to rotate through the meshing between the gears, and in the process of the gear 2 484 rotating, the crushing wheel 47 fixedly connected with the outer surface will be driven to rotate together with the crushing wheel 47 fixedly connected with the outer surface of the transmission 45, so as to crush the polysilicon material for the second time, and then make it into smaller particles.

[0041] Further, please refer to Figure 8 、 Figure 9 and Figure 10As shown, the separation assembly one 3 includes a separation box 31, the right side of the upper end of the separation box 31 is fixedly connected with a fixed plate 32, the left side of the upper end of the fixed plate 32 is fixedly connected with a hinge 34, the left side of the hinge 34 is fixedly connected with a rotating door 35, the right side of the inner cavity of the separation box 31 is fixedly connected with a matching hole 33, two sliding grooves 36 are formed in the left part of the front and rear sides of the inner cavity of the separation box 31, two movable hooks 37 are fixedly connected at the bottom of the front and rear sides of the rotating door 35, and the separation assembly two 38 is movably connected at the bottom of the two movable hooks 37, the separation assembly two 38 includes a sliding box 381, a plurality of filter holes 383 are arranged at the bottom of the inner cavity of the sliding box 381, handles 382 are fixedly connected at the upper part of the front and rear sides of the inner cavity of the sliding box 381, and two sliding strips 384 are fixedly connected at the front and rear sides of the sliding box 381.

[0042] Further, in the specific implementation process of the embodiment, the polycrystalline silicon material in the connecting box 23 is blocked by the filter plate 24 and then falls into the inner cavity of the separation box 31. Because the surface of the matching hole 33 is inclined, the polycrystalline silicon material falls along the slope of the surface of the fixed plate 32 and then falls into the inner cavity of the separation assembly two 38. When the internal storage of the polycrystalline silicon material is sufficient, the detection device in the inner cavity sends a signal to the control console 1 to remind the operator to take it.
