[0002] In the process of smelting industrial raw materials, such as smelting industrial silicon, the cooling ingot mold in the cold casting system currently used is a cast iron ingot mold. The molten metal silicon enters the cooling ingot mold from the silicon bag along the chute. After cooling, it needs to be manually crushed and packaged for storage. The production efficiency is low, resulting in low output, and increased labor intensity and cost.

[0041] In the process of smelting industrial raw materials, such as smelting industrial silicon, the cooling ingot mold in the cold casting system currently used is a cast iron ingot mold. The molten metal silicon enters the cooling ingot mold from the silicon bag along the chute. After cooling, it needs to be manually crushed and packaged for storage. The production efficiency is low, resulting in low output, and increased labor intensity and cost. Moreover, generally a silicon ingot needs to be cooled for more than 24 hours before the subsequent process can be carried out. The cooling time is long, and it takes about 7 times to lift from the completion of casting in the cooling ingot mold to packaging and storage. In addition, due to the long cooling time, the silicon liquid will undergo component segregation during the cooling and solidification process, resulting in uneven distribution of silicon impurity element content, which seriously affects the stability and uniformity of the finished product quality.

[0042] In order to solve the above problems, the present invention provides a cold casting system 100 .

[0043] like Figures 1 to 3 As shown, in one embodiment, the cold casting system 100 includes a support platform 10, a diverter seat 20 installed on the support platform 10, a cooling ingot mold 30 and a vibration mechanism 40, the diverter seat 20 is used to hold the casting liquid, and the diverter seat 20 is provided with a plurality of diverter ports 232 for guiding the casting liquid; the two ends of the cooling ingot mold 30 respectively form a feed end 301 and a discharge end 302, the top of the cooling ingot mold 30 forms a guide surface 32, and the guide surface 32 is gradually increased in height from the feed end 301 to the discharge end 302. The cooling ingot mold 30 is provided with a cooling hole 31 for the entry of coolant, the cooling hole 31 is located below the guide surface 32 and is arranged close to the guide surface 32, the feed end 301 is connected with multiple branch ports 232, the guide surface 32 is used to guide the casting liquid entering the feed end 301 to the discharge end 302, and the cooling ingot mold 30 is used to cool the casting liquid flowing through the guide surface 32, so that the casting liquid forms a block solid; the vibration mechanism 40 is used to drive the cooling ingot mold 30 to vibrate, so as to break and disperse the block solid.

[0044] The cold casting system 100 of the utility model can be used for smelting industrial raw materials, such as smelting industrial silicon, and accordingly, the casting liquid can be silicon liquid. The cold casting system 100 of this embodiment is described by taking the use of smelting industrial silicon as an example.

[0045] In one embodiment of the present utility model, and referring to Figure 1 A diverter seat 20, a cooling ingot mold 30 and a vibration mechanism 40 are installed on the support platform 10. The diverter seat 20 is used to hold the casting liquid, and the diverter seat 20 is provided with a plurality of diverter ports 232 for diverting the casting liquid. Diverting the casting liquid can not only speed up the flow speed, but also evenly transport the casting liquid to the guide surface 32 of the cooling ingot mold 30, thereby avoiding local overheating and burn-through damage of the cooling ingot mold 30.

[0046] like Figure 1 As shown, the left end of the cooling ingot mold 30 is the feed end 301, and the right end is the discharge end 302. A guide surface 32 is formed on the top of the cooling ingot mold 30. The casting liquid entering from the left end is guided from the guide surface 32 to the right end. During the flow of the casting liquid, the cooling ingot mold 30 can cool it. The guide surface 32 is arranged in a stepped surface with a height gradually decreasing from the left end to the right end, which is conducive to the rapid flow of the casting liquid, thereby reducing the cooling time of the casting liquid. The cooling ingot mold 30 is provided with a cooling hole 31 for the coolant to enter. The cooling hole 31 is located below the guide surface 32 and is arranged close to the guide surface 32, so as to promote the rapid solidification of the casting liquid and prevent the uneven distribution of impurity elements due to component segregation of the finished silicon from affecting the quality of the product.

[0047] Moreover, the vibration mechanism 40 can drive the cooling ingot mold 30 to vibrate, further speeding up the flow speed of the casting liquid on the guide surface 32 and reducing the cooling time of the casting liquid. In addition, the cooling ingot mold 30 can also cool the casting liquid flowing through the guide surface 32 into a block solid, and under the action of vibration, the block solid is broken and dispersed and transferred to the right end.

[0048] The cold casting system 100 of the utility model is provided with a diverter seat 20 on the support platform 10, and a plurality of diverter ports 232 are provided on the diverter seat 20 to divert the casting liquid, and a cooling ingot mold 30 is provided. The guide surface 32 on the cooling ingot mold 30 is a stepped surface, which can accelerate the cooling of the casting liquid, thereby reducing the cooling time of the casting liquid, preventing the casting liquid from component segregation during the solidification process, making it difficult to introduce impurities into the cooling ingot mold 30, and improving the stability and uniformity of the finished product quality. In addition, the cold casting system 100 can drive the cooling ingot mold 30 to vibrate by providing a vibration mechanism 40 to break and disperse the block solid, without the need for a manual crushing process, and has the advantages of high production efficiency and increased product output, and reduces manual labor intensity and cost.

[0049] It should be noted that the cooling holes 31 of the cooling ingot mold 30 in the cold casting system 100 of the present utility model can be specifically used to install cold water pipelines, enabling cooling water to flow within the cold water pipelines and promoting the rapid solidification of the casting liquid.

[0050] In the existing process of smelting industrial silicon, the cooling ingot mold 30 used is a cast iron ingot mold. Fe, Al, and Ca are the main impurity elements in metallic silicon. Among them, most of the Al and Ca elements can be removed through oxygen blowing refining, while there is currently no means to remove Fe, which is introduced by raw materials or during the production process. Molten metallic silicon will erode the cast iron ingot mold at high temperatures, bringing the iron elements in the cast iron ingot mold into the finished product, which will not only affect the product quality but also cause losses to the cast iron ingot mold. Approximately 1 kg of the ingot mold will be eroded for one ton of industrial silicon. In the cold casting system 100 of this embodiment, the cooling ingot mold 30 uses a copper mold, which not only has a low cost, is not easy to introduce copper impurities into the casting liquid, but also will not erode the copper mold.

[0051] In one embodiment, the vibration mechanism 40 is located at the bottom of the cooling ingot mold 30. The vibration mechanism 40 includes a vibration module. The vibration module 40a includes a driving component 41, a transmission component 42, and a pushing member 43. The pushing member 43 is vertically arranged. The driving component 41 is installed on the support platform 10. One end of the driving component 41 is connected to the transmission component 42, and the other end of the transmission component 42 is elastically connected to the lower end of the pushing member 43. The upper end of the pushing member 43 is connected to the bottom of the cooling ingot mold 30. The driving component 41 is used to drive the transmission component 42 to drive the pushing member 43 to reciprocate up and down, so as to drive the cooling ingot mold 30 to vibrate up and down.

[0052] As Figures 4 to 5 shown, the driving component 41 of the vibration module 40a can drive the transmission component 42 to drive the pushing member 43 to move up and down. Specifically, one end of the transmission component 42 is elastically connected to the lower end of the pushing member 43, and the upper end of the pushing member 43 is also connected to the cooling ingot mold 30. Therefore, during the up and down movement of the pushing member 43, the cooling ingot mold 30 can be driven to vibrate up and down, so as to realize the process of crushing and dispersing bulk solids through up and down vibration. Moreover, since the cooling ingot mold 30 can vibrate up and down, it can further accelerate the flow rate of the casting liquid, reduce the cooling time, and thus reduce the occurrence of component segregation during the solidification of the casting liquid.

[0053] Furthermore, in order to avoid the situation where the rigid connection between the transmission component 42 and the pushing member 43 causes too high an impact force on the cooling ingot mold 30 and results in unstable vibration of the cooling ingot mold 30, in this embodiment, the method of elastically connecting one end of the transmission component 42 to the lower end of the pushing member 43 is adopted to reduce the impact force on the cooling ingot mold 30 and improve the vibration stability of the cooling ingot mold 30.

[0054] Furthermore, as Figure 4As shown, there are multiple vibration modules 40a, and the multiple vibration modules 40a are evenly distributed at intervals. By setting multiple vibration modules 40a, the power source for the up and down vibration of the cooling ingot mold 30 is improved, ensuring the vibration reliability and stability of the cooling ingot mold 30.

[0055] In one embodiment, the transmission assembly 42 includes a connecting block 421 and a guide post 422. The guide post 422 is vertically arranged. The driving assembly 41 is connected to the lower end of the guide post 422 through the connecting block 421. An installation cavity 4221 is provided in the guide post 422. The pushing member 43 is a push rod 43a. The lower end of the push rod 43a extends into the installation cavity 4221 and is slidably matched with the cavity wall of the installation cavity 4221. The upper end of the push rod 43a extends out of the installation cavity 4221 from the upper end of the guide post 422 and is connected to the bottom of the cooling ingot mold 30. An elastic member 424 is provided in the installation cavity 4221. The upper and lower ends of the elastic member 424 are respectively abutted against the cavity wall of the installation cavity 4221 and the lower end of the push rod 43a. The driving assembly 41 is used to drive the guide post 422 to reciprocate up and down through the connecting block 421, so as to drive the push rod 43a to reciprocate up and down through the elastic member 424.

[0056] As Figure 6 shown, the driving assembly 41 drives the guide post 422 to move up and down through the connecting block 42. The installation cavity 4221 provided in the guide post 422 is slidably matched with the push rod 43a, so as to play a guiding role for the push rod 43a through the guide post 422. When the driving assembly 41 drives the guide post 422 to move upward through the connecting block 421, the elastic member 424 can drive the push rod 43a to move upward stably. When the driving assembly 41 drives the guide post 422 to move downward through the connecting block 421, the elastic member 424 can drive the push rod 43a to move downward stably, ensuring the stability of the push rod 43a during the up and down movement.

[0057] Specifically, the elastic member 424 can be a spring sleeved on the push rod 43a. The push rod 43a can play a guiding and limiting role for the spring, which is beneficial to the stable expansion and contraction of the spring. Moreover, the spring has the advantages of good elastic effect, low cost and easy material selection.

[0058] In one embodiment, the transmission assembly 42 further includes a transmission seat 423. The transmission seat 423 includes a sleeve 4231 and a top plate 4232 provided at the top of the sleeve 4231. The bottom of the sleeve 4231 is open. A sliding cavity 4233 communicating with the open end is formed in the sleeve 4231. The upper end of the guide post 422 extends into the sliding cavity 4233 from the open end and is slidably matched with the inner wall of the sleeve 4231. The upper end of the push rod 43a is located in the sliding cavity 4233 and is connected to the top plate 4232. The top plate 4232 is connected to the bottom of the cooling ingot mold 30.

[0059] As Figure 6As shown, the sliding cavity 4233 provided inside the sleeve 4231 is in sliding fit with the upper end of the guide post 422, so as to guide the guide post 422 through the sleeve 4231. The top plate 4232 provided at the top of the sleeve 4231 can increase the contact area with the cooling ingot mold 30 and improve the vibration stability of the cooling ingot mold 30.

[0060] In one embodiment, the vibration mechanism 40 further includes a first support plate 45, a second support plate 46 and a buffer module 44. The buffer module 44 includes an elastic mounting post 441 and a buffer spring 442. The first support plate 45 is mounted on the support table 10. A driving assembly 41 is mounted on the first support plate 45. The second support plate 46 is located above the first support plate 45, and the top of the second support plate 46 is connected to the cooling ingot mold 30. The bottom of the second support plate 46 is connected to the top plate 4232. The first support plate 45 and the second support plate 46 are connected by elastic mounting posts 441. A buffer spring 442 is sleeved outside the elastic mounting post 441, and the upper and lower ends of the buffer spring 442 are respectively abutted against the second support plate 46 and the first support plate 45.

[0061] As Figure 4 shown, the top of the second support plate 46 is connected to the cooling ingot mold 30, which provides stable support for the cooling ingot mold 30, increases the contact area with the cooling ingot mold 30, and improves the vibration stability of the cooling ingot mold 30. The elastic mounting posts 441 and buffer springs 442 provided between the first support plate 45 and the second support plate 46 can undergo elastic deformation during the up and down vibration of the vibration mechanism 40, playing a buffering effect, reducing the impact force on the cooling ingot mold 30, and improving the vibration stability of the cooling ingot mold 30.

[0062] Further, both the first support plate 45 and the second support plate 46 are in the shape of a cuboid, and the first support plate 45 and the second support plate 46 are arranged in parallel. The bottom of the cooling ingot mold 30 is also configured as a plane matching the second support plate 46, which is conducive to assembly and can improve the vibration stability of the cooling ingot mold 30.

[0063] As Figure 1 shown, the number of the buffer modules 44 can be multiple, enhancing the buffering effect on the cooling ingot mold 30 and further improving the vibration stability of the cooling ingot mold 30. In one embodiment, for example, the number of the buffer modules 44 is five. Four of the buffer modules 44 are distributed at the four corners of the space enclosed by the first support plate 45 and the second support plate 46, and the remaining one buffer module 44 is arranged in the middle of the space, with a reasonable layout.

[0064] In one embodiment, the driving assembly 41 includes a rotating driving member 411 and a cam 412. The rotating driving member 411 is installed on the support platform 10. The output shaft of the rotating driving member 411 extends in the horizontal direction and is connected to the cam 412. The outer edge of the cam 412 is connected to the bottom of the connecting block 421. The top of the connecting block 421 is connected to the lower end of the guide column 422. The rotating driving member 411 is used to drive the cam 412 to rotate around the output shaft, so as to drive the connecting block 421 and the guide column 422 to reciprocate and rise and fall through the outer edge of the cam 412.

[0065] like Figure 6 As shown, the rotary drive member 411 drives the cam 412 to rotate through the output shaft, and the outer edge of the cam 412 drives the connecting block 421 and the guide column 422 to move up and down. In this embodiment, the driving assembly 41 adopts the method of the rotary drive member 411 driving the cam 412 to realize the up and down movement of the guide column 422, which simplifies the structure of the driving assembly 41 and facilitates manufacturing.

[0066] Furthermore, the rotary drive member 411 may be a servo motor, a stepper motor, an asynchronous motor, or a rotary hydraulic cylinder, which has a simple structure and is easy to install.

[0067] In one embodiment, the cold casting system 100 also includes a material shifting mechanism 50, which is located at the discharge end 302. The material shifting mechanism 50 includes a roller 51 and a support seat 52. The support seat 52 is installed on the support platform 10. The roller 51 is horizontally arranged in a direction perpendicular to the feed end 301 to the discharge end 302, and the roller 51 is rotatably installed on the support platform 10 and is located above the guide surface 32. A plurality of paddles 53 are provided on the outer periphery of the roller 51. The plurality of paddles 53 are driven to rotate by driving the roller 51 to rotate, so that the plurality of paddles 53 shift the block solid to the direction of the discharge end 302.

[0068] like Figure 1 As shown, the material-shifting mechanism 50 is installed at the right end near the cooling ingot mold 30, that is, at the discharge end 302 of the cooling ingot mold 30. By driving the roller 51 in the material-shifting mechanism 50 to rotate, since a plurality of paddles 53 are provided on the roller 51, the plurality of paddles 53 can shift the block solid toward the right end, which is convenient for quickly collecting the block solid and has high working efficiency.

[0069] It should be noted that the driving method of the roller shaft 51 in this embodiment can be flexibly set, and the roller shaft 51 can be driven manually or driven by a motor to rotate, which saves time and effort. When the roller shaft 51 is driven by a motor, the motor can be set on the support seat 52, and the structure is compact.

[0070] like Figure 3As shown, a plurality of paddle groups are arranged at intervals along the circumferential direction on the roller shaft 51, and each paddle group includes a plurality of paddles 53 arranged at intervals along the axial direction of the roller shaft 51. By providing a plurality of paddle groups, the efficiency of collecting bulk solids can be further improved and time can be saved.

[0071] In one embodiment, a collection frame may be provided below the guide surface 32 at the discharge end 302 of the cooling ingot mold 30 to collect the block solids.

[0072] In one embodiment, the cold casting system 100 further includes a tilting mechanism 60 , which is installed on the support platform 10 and disposed close to the manifold seat 20 . The tilting mechanism 60 is used to pour the casting liquid into the manifold seat 20 .

[0073] like Figure 2 As shown, the tipping mechanism 60 includes a liquid storage barrel 61, a first hydraulic rod 62 and a second hydraulic rod 63, a support frame 64 and a mounting clamp 65. The mounting clamp 65 is fixedly sleeved on the outer peripheral wall of the liquid storage barrel 61. The two ends of the support frame 64 are respectively a first hinged end and a second hinged end. The first hinged end is hinged to one side of the mounting clamp 65 through a first hinge axis, and the second hinged end is hinged to the support platform 10 through a second hinge axis. The first hydraulic rod 62 is installed on the support platform 10. The hydraulic end of the first hydraulic rod 62 is hinged to the support frame 64 at a position between the first hinged end and the second hinged end. One end of the second hydraulic rod 63 is hinged to the support platform 10, and the other end is hinged to the mounting clamp 65.

[0074] The liquid storage barrel 61 can store casting liquid, and a casting port is formed at one end of the liquid storage barrel 61. When casting is required, the first hydraulic rod 62 extends upward to drive the support frame 64 to rotate counterclockwise, so that the liquid storage barrel 61 moves from the initial position to the preset position, and then the second hydraulic cylinder 63 extends to rotate the mounting hoop 65 and the liquid storage barrel 61 around the first hinge axis, so that the liquid storage barrel 61 rotates from the vertical state to the tilting state, so that the casting liquid in the liquid storage barrel 61 is tilted from the casting port to the diverter seat 20, so that the tilting mechanism 60 is set to realize the pouring process of the casting liquid, which saves time and effort and is easy to operate.

[0075] It can be understood that the dumping state is an inclined state or a horizontal state or a state close to the horizontal state, and it is sufficient to dump the casting liquid in the liquid storage barrel 61 from the casting port into the diverter seat 20 .

[0076] Further, the V-shaped support frame 64 specifically includes a first support rod 641 and a second support rod 642. One end of the first support rod 641 is connected to one end of the second support rod 642. The connection point of one end of the first support rod 641 and one end of the second support rod 642 is hinged to one side of the mounting hoop 65 through a first hinge shaft, that is, one end of the first support rod 641 and one end of the second support rod 642 form a first hinge end. The other end of the first support rod 641 is hinged to the support platform 10 through a second hinge shaft, that is, the other end of the first support rod 641 is a second hinge end. A first hydraulic rod 62 is installed on the support platform 10. The hydraulic end of the first hydraulic rod 62 is hinged to a position on the first support rod 641 between one end and the other end of the first support rod 641. The other end of the second support rod 642 can be used as a support end to support on the support platform 10 to play a supporting role when the liquid storage barrel 61 pours the casting liquid, ensuring the stability of the liquid storage barrel 61 during the pouring process.

[0077] In one embodiment, refractory layers 70 are provided on the upper surface of the support platform 10 near the tipping mechanism 60 and the flow dividing seat 20 to prevent damage to the support platform 10. The material of the refractory layer 70 is not limited.

[0078] In one embodiment, the flow dividing seat 20 includes a seat body 24 and an overflow groove 21, a diversion groove 22, and a flow dividing groove 23 all installed on the seat body. The seat body 24 is installed on the support platform 10. The overflow groove 21 and the flow dividing groove 23 are communicated through the diversion groove 22. The overflow groove 21 is used to hold the casting liquid. A plurality of flow dividing plates 231 are provided at intervals on the bottom of the flow dividing groove 23 to divide the flow dividing groove 23 into multiple flow paths. One end of each flow path away from the diversion groove 22 forms a flow dividing port 232.

[0079] As Figures 7 to 9 shown, the overflow groove 21 is used to hold the casting liquid, which can prevent the casting liquid from overflowing the flow dividing seat 20 during casting. Two flow dividing plates 231 are provided at intervals on the bottom of the flow dividing groove 23 to divide the flow dividing groove 23 into two flow paths. One end of each flow path away from the diversion groove 22 forms a flow dividing port 232. The flow dividing port 232 can divide the flow, accelerate the flow rate of the casting liquid, reduce the cooling time, and evenly cast the casting liquid onto the cooling ingot mold 30, avoiding local overheating and burning through damage of the cooling ingot mold 30.

[0080] Further, the material of the flow dividing seat 20 can be made of alumina material. The impurities in the silicon liquid contain Al and Ca impurities, and the freezing points of Al and Ca impurities are higher than the freezing point of the silicon liquid, so that the Al and Ca impurities can first solidify in the flow dividing seat 20 to form impurity bodies. The impurity bodies are convenient for depositing at the bottom of the overflow groove 21, the diversion groove 22, and the flow dividing groove 23. Thus, most of the Al and Ca impurities can be removed in the flow dividing seat 20, improving the product quality, and no subsequent manual finishing process is required, further accelerating the production efficiency.

[0081] Furthermore, one end of the flow dividing plate 231 close to the diversion groove 22 is arranged in an arc shape, which is convenient for diversion and improves the flow dividing effect.

[0082] In one embodiment, one end of the overflow groove 21 far from the diversion groove 22 forms a feeding end, and the end where the flow dividing opening 232 is located is the discharging end. The size of the diversion groove 22 is gradually expanded from the feeding end towards the discharging end, and the size of the flow dividing groove 23 is gradually expanded from the feeding end towards the discharging end. The bottom of the overflow groove 21, the bottom of the diversion groove 22, and the bottom of the flow dividing groove 23 form a flow surface, and the flow surface is an arc surface with decreasing height in the direction from the feeding end to the discharging end.

[0083] As Figure 8 shown, the left end of the overflow groove 21 is the feeding end, and the right end where the flow dividing opening 232 is located is the discharging end. The size of the diversion groove 22, specifically the size of the cross-section, is gradually expanded from the left end towards the right end, that is, the size of the diversion groove 22 in the front-back direction gradually increases towards the right, which plays a role in buffering, decelerating, and guiding the casting liquid in the diversion groove 22. The size of the flow dividing groove 23, specifically the size of the cross-section, is gradually expanded from the left end towards the right end, that is, the size of the flow dividing groove 23 in the front-back direction gradually increases towards the right, which plays a role in buffering, decelerating, and guiding the casting liquid in the flow dividing groove 23. The bottom of the overflow groove 21, the bottom of the diversion groove 22, and the bottom of the flow dividing groove 23 form a flow surface, and the flow surface is an arc surface with decreasing height in the direction from the left end to the right end, which is convenient for the smooth flow of the casting liquid and accelerates the flow speed of the casting liquid.

[0084] In one embodiment, there are multiple cooling ingot molds 30, and the multiple cooling ingot molds 30 are arranged in sequence along the direction from the feeding end 301 to the discharging end 302. Moreover, the multiple diversion surfaces 32 are arranged in a stepped manner with decreasing height along the direction from the feeding end 301 to the discharging end 302. Cooling holes 31 are provided at the positions below each step of the diversion surface 32 corresponding to each cooling ingot mold 30; among any two adjacent cooling ingot molds 30, the discharging end 302 of one cooling ingot mold 30 is communicated with the feeding end 301 of the other cooling ingot mold 30. The feeding end 301 of the cooling ingot mold 30 close to the flow dividing seat 20 is located below the multiple flow dividing openings 232 and is communicated with all the multiple flow dividing openings 232; each cooling ingot mold 30 is correspondingly provided with a vibration mechanism 40, and the vibration mechanism 40 is used to drive the corresponding cooling ingot mold 30 to vibrate.

[0085] As Figure 1 shown, the multiple cooling ingot molds 30 are arranged in sequence along the direction from the left end to the right end, and the multiple diversion surfaces 32 corresponding to each cooling ingot mold 30 are arranged in a stepped manner with gradually decreasing height along the direction from the left end to the right end, which accelerates the flow speed of the casting liquid and reduces the cooling time.

[0086] Taking the number of the cooling ingot molds 30 as three as an example for illustration, the feeding end 301 of the leftmost cooling ingot mold 30 is communicated with a plurality of shunt ports 232. The discharging end 302 of the leftmost cooling ingot mold 30 is communicated with the feeding end 301 of the rightmost cooling ingot mold 30 through the middle cooling ingot mold 30. The discharging end 302 of the rightmost cooling ingot mold 30 is below the roller shaft 51, which is convenient for the smoothness and continuity of the flow of the casting liquid.

[0087] A vibration mechanism 40 can be correspondingly arranged for each cooling ingot mold 30, which can ensure the stability of the up-and-down vibration of the cooling ingot mold 30 and is convenient for controlling the vibration frequency.

[0088] In other embodiments, a plurality of cooling ingot molds 30 can share one vibration mechanism 40, which simplifies the structure and has a low cost.

[0089] It can be understood that cooling holes 31 are arranged at the positions below each step of the corresponding guiding surface 32 of each cooling ingot mold 30. The cooling water flows in the cold water pipeline, which further accelerates the solidification speed of the casting liquid and prevents the uneven distribution of impurity elements caused by composition segregation of the finished silicon from affecting the quality of the product.

[0090] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
