Description

Technical Field

[0001] This utility model relates to the technical field of silicon casting equipment, and in particular to a tilting device for industrial silicon casting. Background Technology

[0002] In the industrial silicon molten silicon casting process, the ingot mold trolley moves the ingot mold to the casting station. A tilting drive mechanism then drives a tilting frame to tilt the ladle, causing the molten silicon in the ladle to pour out and be used to cast the ingot mold. Typically, each ladle of molten silicon can continuously cast multiple ingot molds. When the current ingot mold is finished casting, the ladle's rotation must be restricted, and the tilting angle locked at the current position. Once the next ingot mold has moved to the casting station, the tilting angle restriction is lifted, allowing the ladle to continue rotating and casting the subsequent ingot mold.

[0003] In existing silicon molten metal casting processes, when the current ingot mold casting is completed, the rotation of the ladle is restricted by pausing the drive components. However, this operation is prone to causing the tilting angle of the ladle to be too large or too small, making it difficult to accurately lock the tilting angle at the target position. If the tilting angle of the ladle is too large, it will result in an excessive amount of ingot mold casting; if the tilting angle of the ladle is too small, it will result in an insufficient amount of ingot mold casting, which will seriously affect the casting quality of the ingot mold. Utility Model Content

[0004] The main purpose of this invention is to propose a tilting device for industrial silicon casting, which aims to solve the technical problem that the tilting angle of the ladle is difficult to control precisely in the silicon casting process in the prior art.

[0005] To achieve the above objectives, the present invention proposes a tilting device for industrial silicon casting, comprising:

[0006] A tilting mechanism, comprising a support base, a tilting shaft, a tilting drive component, and a lifting bag and a tilting frame connected to each other, wherein one end of the tilting shaft is fixed to the tilting frame, and the other end of the tilting shaft is rotatably mounted on the support base, the tilting drive component is disposed on the support base, and the tilting drive component is connected to the tilting frame in a transmission manner;

[0007] The limiting mechanism includes a first limiting member and a second limiting member. The first limiting member is sleeved on the tilting shaft and has multiple receiving portions distributed circumferentially along the tilting shaft. The second limiting member includes a telescopic portion and a fixed portion. The fixed portion is fixedly connected to the support base, and the telescopic portion is movably installed on the fixed portion so that it can extend into or leave the receiving portion. When the telescopic portion leaves the receiving portion, the tilting drive can drive the lifting bag to tilt via the tilting frame. When the telescopic portion extends into the receiving portion, it can restrict the rotation of the lifting bag.

[0008] In one embodiment, the telescopic part includes a limiting member and a telescopic drive member. The limiting member is movably mounted on the fixed part, and the telescopic drive member is throttle-connected to the limiting member so that the telescopic drive member can drive the limiting member to extend into or leave the receiving part.

[0009] In one embodiment, the fixing part has a telescopic hole through which the limiting member passes, the telescopic hole extends radially along the tilting shaft, and the limiting member slides in conjunction with the telescopic hole.

[0010] In one embodiment, the fixing part is provided with a receiving cavity for accommodating the telescopic drive member, and the receiving cavity is in communication with the telescopic hole.

[0011] In one embodiment, the tilting device for industrial silicon casting further includes a monitoring module electrically connected to the tilting drive component, so that the monitoring module can acquire the elongation of the tilting drive component.

[0012] In one embodiment, the tilting device for industrial silicon casting further includes a control module, which is electrically connected to the monitoring module and the tilting drive component, respectively. The control module is capable of adjusting the speed and angle at which the tilting drive component drives the tilting frame to rotate.

[0013] In one embodiment, the number of limiting mechanisms is at least two.

[0014] In one embodiment, the tilting shaft is an aluminum-silicon alloy tilting shaft.

[0015] In one embodiment, the support base includes a base and a first support frame and a second support frame. The first support frame and the second support frame are spaced apart from each other on the base along a first direction. One end of the tilting shaft is rotatably mounted on the first support frame, and the other end of the tilting shaft is rotatably mounted on the second support frame.

[0016] In one embodiment, the first support frame includes a first support rod and a second support rod connected to each other; one end of the first support rod is fixed to the base, the other end of the first support rod is connected to one end of the second support rod, and the other end of the second support rod is fixed to the base; the included angle between the first support rod and the second support rod is defined as θ, where 60°≤θ≤70°.

[0017] And / or, the second support frame includes a first support part and a second support part connected to each other; one end of the first support part is fixed to the base, the other end of the first support part is connected to one end of the second support part, the other end of the second support part is fixed to the base, and the included angle between the first support part and the second support part is defined as α, 60°≤α≤70°;

[0018] And / or, the tilting shaft includes a first shaft and a second shaft, both of which are connected to the tilting frame. The first shaft and the second shaft are spaced apart along the first direction. The first shaft is rotatably mounted on the first support frame, and the second shaft is rotatably mounted on the second support frame.

[0019] In this invention, when molten silicon needs to be cast, the telescopic part moves away from the receiving part, and the tilting drive can tilt the ladle via the tilting frame, causing the molten silicon in the ladle to pour out and be cast into the ingot mold. When it is necessary to stop at a certain angle, the telescopic part extends into the receiving part to restrict the ladle from continuing to rotate. In this way, even if the drive extends too far or retracts, the tilting angle of the ladle will not be too large or too small. This reduces the risk of deviation in the tilting angle of the ladle caused by relying solely on the tilting drive to restrict the continued rotation of the ladle, which helps to improve the control accuracy of the tilting angle of the ladle and ensure the quality of ingot mold casting.

[0031] In the industrial silicon molten silicon casting process, the ingot mold trolley moves the ingot mold to the casting station. A tilting drive mechanism then drives a tilting frame to tilt the ladle, causing the molten silicon in the ladle to pour out and be used to cast the ingot mold. Typically, each ladle of molten silicon can continuously cast multiple ingot molds. When the current ingot mold is finished casting, the ladle's rotation must be restricted, and the tilting angle locked at the current position. Once the next ingot mold has moved to the casting station, the tilting angle restriction is lifted, allowing the ladle to continue rotating and casting the subsequent ingot mold.

[0032] In existing silicon molten metal casting processes, when the current ingot mold casting is completed, the rotation of the ladle is restricted by pausing the drive components. However, this operation is prone to causing the tilting angle of the ladle to be too large or too small, making it difficult to accurately lock the tilting angle at the target position. If the tilting angle of the ladle is too large, it will result in an excessive amount of ingot mold casting; if the tilting angle of the ladle is too small, it will result in an insufficient amount of ingot mold casting, which will seriously affect the casting quality of the ingot mold.

[0033] The inventors discovered that when the ingot casting is completed, most traditional tilting devices use a drive component to restrict the ladle from continuing to rotate, thus stopping the ladle at a certain angle. However, in this operation of restricting the ladle from continuing to rotate, the drive component often causes the tilting angle of the ladle to be too large due to overextending or too small due to retracting.

[0034] To solve the above-mentioned technical problems, this utility model proposes a tilting device for industrial silicon casting.

[0035] Please see Figures 1 to 3 In one embodiment of this utility model, the tilting device 100 for industrial silicon casting includes a tilting mechanism 1 and a limiting mechanism 2. The tilting mechanism 1 includes a support base 11, a tilting shaft 12, a tilting drive component 13, and a lifting bag 14 and a tilting frame 15 connected to each other. One end of the tilting shaft 12 is fixed to the tilting frame 15, and the other end of the tilting shaft 12 is rotatably mounted on the support base 11. The tilting drive component 13 is disposed on the support base 11 and is connected to the tilting frame 15 in a transmission manner. The limiting mechanism 2 includes a first limiting component 21 and a second limiting component 22. The first limiting component 21 is sleeved on the tilting shaft 12. The limiting member 21 is provided with a plurality of receiving portions 211, which are distributed circumferentially along the tilting shaft 12. The second limiting member 22 includes a telescopic portion 221 and a fixed portion 222. The fixed portion 222 is fixedly connected to the support base 11. The telescopic portion 221 is movably installed on the fixed portion 222 so that the telescopic portion 221 can extend into or leave the receiving portion 211. When the telescopic portion 221 leaves the receiving portion 211, the tilting drive member 13 can drive the lifting bag 14 to tilt through the tilting frame 15. When the telescopic portion 221 extends into the receiving portion 211, the telescopic portion 221 can restrict the rotation of the lifting bag 14.

[0036] When the silicon molten material needs to be cast, the telescopic part 221 moves away from the receiving part 211, and the tilting drive 13 can drive the lifting ladle 14 to tilt through the tilting frame 15, so that the silicon molten material in the lifting ladle 14 is poured out to cast the ingot mold. When it is necessary to stop at a certain angle, the telescopic part 221 extends into the receiving part 211 to restrict the lifting ladle 14 from continuing to rotate. In this way, even if the drive extends too far or retracts, the tilting angle of the lifting ladle 14 will not be too large or too small. This reduces the risk of deviation in the tilting angle of the lifting ladle 14 caused by simply relying on the tilting drive 13 to restrict the continued rotation of the lifting ladle 14. It is beneficial to improve the control accuracy of the tilting angle of the lifting ladle 14 and ensure the quality of ingot mold casting.

[0037] In this embodiment, the tilting shaft 12 and the support base 11 can be connected by bearings, pins, or a shaft-hole fit, without limitation. The tilting drive 13 can be a hydraulic rod or a cylinder, without limitation. Specifically, the tilting drive 13 is a hydraulic rod, one end of which is fixed to the support base 11, and the other end is connected to the tilting frame 15. The extension or retraction of the hydraulic rod can drive the tilting frame 15 to rotate around the tilting shaft 12, thereby causing the lifting bale 14 to tilt around the tilting shaft 12, pouring out the molten silicon in the lifting bale 14 for casting the ingot mold. The transmission connection between the tilting drive 13 and the tilting frame 15 can be a gear drive, chain drive, or linkage drive, without limitation. The receiving part 211 can be a receiving groove directly formed on the first limiting member 21, or a receiving hole directly formed on the first limiting member 21, without limitation. The telescopic part 221 can be movably mounted on the fixed part 222 via a telescopic cylinder or a slider guide rail, without limitation.

[0038] Please see Figure 3 and Figure 4In one embodiment, the telescopic part 221 includes a limiting member 2211 and a telescopic drive member. The limiting member 2211 is movably mounted on the fixed part 222, and the telescopic drive member is convexly connected to the limiting member 2211 so that the telescopic drive member can drive the limiting member 2211 to extend into or leave the receiving part 211. When it is necessary to cast molten silicon, the telescopic drive member can drive the limiting member 2211 to leave the receiving part 211, thereby enabling the tilting drive member 13 to tilt the ladle 14 in a timely manner through the tilting frame 15, which is beneficial to improving the efficiency of molten silicon casting. When it is necessary to stop at a certain angle, the telescopic drive member can drive the limiting member 2211 to extend into the receiving part 211, thereby timely limiting the ladle 14 from continuing to tilt, which is beneficial to improving the control accuracy of the tilting angle of the ladle 14. In this embodiment, the limiting member 2211 can be a limiting block, a limiting post, or a limiting plate, and is not limited thereto. The telescopic drive component can be hydraulically driven, electrically driven, or magnetically driven, and there is no limitation herein. The transmission connection between the telescopic drive component and the limiting component 2211 can be gear transmission, chain transmission, or linkage transmission, and there is no limitation herein.

[0039] Please see Figure 1 and Figure 3 In one embodiment, the fixing part 222 has a telescopic hole through which the limiting member 2211 passes. The telescopic hole extends radially along the tilting shaft 12. The limiting member 2211 slides with the telescopic hole, which can constrain the movement trajectory of the limiting member 2211. This helps to reduce the risk of mispositioning when the limiting member 2211 enters the receiving part 211 or jamming when it leaves the receiving part 211, thereby improving the fitting accuracy between the limiting member 2211 and the receiving part 211.

[0040] Please see Figure 3 In one embodiment, the fixing part 222 is provided with a receiving cavity for accommodating the telescopic drive component, and the receiving cavity is connected to the telescopic hole. The receiving cavity can provide a closed working environment for the telescopic drive component, which is beneficial for isolating external pollutants such as dust and liquids and other obstacles, and helps to reduce the risk of the drive component malfunctioning due to environmental erosion or interference from obstacles.

[0041] In the current industrial silicon casting process, the tilting angle of the ladle and the casting speed are difficult to control precisely, resulting in highly unstable casting speed of molten silicon, which in turn affects the casting operation. If the casting speed is too fast, it will drastically accelerate the thermal erosion of the ingot mold, significantly increasing the iron content in the finished industrial silicon product, and also shortening the service life of the ingot mold, increasing the production cost of industrial silicon. Conversely, if the casting speed is too slow, the remaining molten silicon in the ladle will stick to the ladle due to the low temperature, resulting in the loss of finished industrial silicon and affecting the quality of the finished product.

[0042] The inventors discovered that traditional tilting devices mostly rely on manual remote control to adjust the casting speed and tilting angle of the molten silicon ladle. Due to differences in the experience level of casting workers and the malfunctions of remote control equipment during actual operation, it is difficult to accurately control the casting speed and tilting angle of the molten silicon ladle.

[0043] To improve the control accuracy of the pouring speed and tilting angle during the silicon molten metal casting process, please refer to [link to relevant documentation]. Figure 2 In one embodiment, the tilting device 100 for industrial silicon casting further includes a monitoring module 3, which is electrically connected to the tilting drive 13 so that the monitoring module 3 can acquire the elongation of the tilting drive 13.

[0044] Please see Figure 2 and Figure 3 In one embodiment, the tilting device 100 for industrial silicon casting further includes a control module 4, which is electrically connected to the monitoring module 3 and the tilting drive component 13. The control module 4 can adjust the speed and angle at which the tilting drive component 13 drives the tilting frame 15 to rotate.

[0045] During the silicon molten metal casting process, the control module 4 sets the tilting speed and the tilting angle required for the ingot mold lifting ladle 14 to be cast. The control module 4 calculates the elongation of the tilting drive component 13 per unit time based on the tilting speed and the required elongation of the tilting drive component 13 based on the tilting angle required for the ingot mold lifting ladle 14. When the ingot mold is moved to the designated position, the tilting drive component 13 extends with an elongation corresponding to the tilting speed under the control of the control module 4, thereby driving the tilting frame 15 to tilt the lifting ladle 14, thus pouring out the silicon molten metal in the lifting ladle 14 to cast the ingot mold. Simultaneously, the monitoring module 3 continuously monitors the elongation of the tilting drive component 13 and transmits the monitoring data to the control module 4. When the monitoring module 3 detects that the elongation of the tilting drive component 13 reaches the elongation required for casting an ingot mold as calculated by the control module 4, the control module... 4. Based on the monitoring data from the monitoring module 3, the tilting drive component 13 is controlled to pause its extension. After the next ingot mold is delivered to the designated position, the control module 4 controls the tilting drive component 13 to continue extending, thereby achieving precise control over the casting speed and tilting angle of the ladle 14. This improves the stability of the silicon molten metal casting speed, effectively avoids the problem of ingot mold erosion caused by excessively fast casting or ladle sticking caused by excessively slow casting, thereby increasing the service life of the ingot mold, reducing the loss rate of industrial silicon finished product output, and ensuring the quality of industrial silicon finished products.

[0046] The control module 4 is also electrically connected to the telescopic drive component. Based on the elongation of the tilting drive component 13 fed back by the monitoring module 3, the control module 4 controls the telescopic drive component to extend the limiting component 2211 into or out of the receiving portion 211. When the monitoring module 3 detects that the elongation of the tilting drive component 13 reaches the elongation required for casting an ingot mold as calculated by the control module 4, the control module 4 controls the tilting drive component 13 to pause its elongation based on the monitoring data from the monitoring module 3. Simultaneously, it controls the telescopic drive component to extend the limiting component 2211 into the receiving portion 211 to restrict the continued rotation of the ladle 14. This reduces the risk of deviation in the tilting angle of the ladle 14 caused by solely relying on the tilting drive component 13 to restrict the continued rotation of the ladle 14, thus improving the control accuracy of the tilting angle of the ladle 14 and ensuring the casting quality of the ingot mold.

[0047] For a specific implementation process of the above embodiments, please refer to Figures 1 to 3During the casting process, each ladle of molten silica can continuously cast multiple ingot molds. Taking the example that one ladle of molten silica can continuously cast 5 ingot molds, casting one ingot mold takes 5 minutes, and the total casting time is 25 minutes. If the final tilting angle is 90°, then the tilting speed of ladle 14 is 0.06° / s, and ladle 14 needs to tilt 18° to cast one ingot mold. The operator sets the tilting speed and the tilting angle required for ladle 14 to cast one ingot mold through control module 4. Control module 4 calculates the elongation per second of the tilting drive component 13 based on the tilting speed (0.06° / s) and calculates the elongation required to cast one ingot mold based on the tilting angle (18°) required for ladle 14 to cast one ingot mold. When the first ingot mold is moved to the designated position, the tilting drive 13 extends at a tilting speed (0.06° / s) under the control of the control module 4, thereby driving the tilting frame 15 to tilt the ladle 14 at a speed of 0.06° / s, pouring out the molten silica in the ladle 14 to cast the first ingot mold. At the same time, the monitoring module 3 continuously monitors the extension of the tilting drive 13 and transmits the monitoring data to the control module 4. When the monitoring module 3 detects that the extension of the tilting drive 13 reaches the extension corresponding to 18°, the control module 4 controls the tilting drive 13 to stop extending according to the monitoring data of the monitoring module 3. At the same time, it controls the telescopic drive to drive the limiting member 2211 to extend into the receiving part 211 to restrict the ladle 14 from continuing to rotate. This reduces the risk of deviation of the tilting angle of the ladle 14 caused by relying solely on the tilting drive 13 to restrict the ladle 14 from continuing to rotate, which is beneficial to improving the control accuracy of the tilting angle of the ladle 14 and ensuring the casting quality of the ingot mold. After the second ingot mold moves to the designated position (the ingot mold moving time is not included in the total casting time), the control module 4 controls the telescopic drive to move the limiting piece 2211 away from the receiving part 211, and controls the tilting drive 13 to drive the tilting frame 15 to continue tilting the ladle 14, thereby casting the second ingot mold. After all five ingot molds have been cast, the control module 4 controls the tilting drive 13 to retract, thereby driving the tilting frame 15 to rotate the ladle 14 to the initial position, and controls the telescopic drive to move the limiting piece 2211 into the receiving part 211 to restrict the rotation of the ladle 14, thereby precisely controlling the initial tilting angle of the ladle 14.

[0048] Please see Figure 1 In one embodiment, the number of limiting mechanisms 2 is at least two. In this embodiment, the number of limiting mechanisms 2 can be two or more, and there is no limitation. Specifically, the number of limiting mechanisms 2 is two. The two limiting mechanisms 2 can enhance the limiting strength of the lifting bag 14, thereby helping to improve the control accuracy of the tilting angle of the lifting bag 14.

[0049] Please see Figure 1In one embodiment, the tilting shaft 12 is an aluminum-silicon alloy tilting shaft 12, which helps to reduce the risk of deformation or breakage of the tilting shaft 12 when subjected to high temperature silicon water heavy load and high temperature flue gas environment, thereby helping to ensure the reliable operation of the tilting mechanism 1.

[0050] Please see Figure 1 , Figure 1 The left-right direction is defined as the first direction. In one embodiment, the support base 11 includes a base 111, a first support frame 112, and a second support frame 113. The first support frame 112 and the second support frame 113 are spaced apart from each other along the first direction on the base 111. One end of the tilting shaft 12 is rotatably mounted on the first support frame 112, and the other end of the tilting shaft 12 is rotatably mounted on the second support frame 113. In this embodiment, the number of the first support frame 112 and the second support frame 113 can be one, two, or more, and there is no limitation. Specifically, there is one first support frame 112 and one second support frame 113. The first support frame 112 and the second support frame 113 are fixed on both sides of the base 111 respectively. One end of the tilting shaft 12 is rotatably mounted on the first support frame 112, and the other end of the tilting shaft 12 is rotatably mounted on the second support frame 113. The first support frame 112 and the second support frame 113 support the two force points of the tilting shaft 12 respectively, so that the lifting bag 14 is supported by two directions, which helps to improve the stability of the lifting bag 14, and thus helps to improve the overall stability of the tilting mechanism 1.

[0051] Please see Figure 1 In one embodiment, the first support frame 112 includes a first support rod 1121 and a second support rod 1122 connected to each other. One end of the first support rod 1121 is fixed to the base 111, and the other end of the first support rod 1121 is connected to one end of the second support rod 1122. The other end of the second support rod 1122 is fixed to the base 111. The included angle between the first support rod 1121 and the second support rod 1122 is defined as θ, where 60°≤θ≤70°. In this embodiment, the included angle θ formed between the first support rod 1121 and the second support rod 1122 can be 60° or 70°, and is not limited here. The triangular truss formed by the first support rod 1121 and the second support rod 1122 can distribute the load borne by the support frame, which is beneficial to improving the bending strength and deformation resistance of the support frame, and thus helps to adapt to the dynamic impact when the molten silicon is poured, enhancing the overturning resistance of the support frame.

[0052] In one implementation, please refer to Figure 1The second support frame 113 includes a first support part 1131 and a second support part 1132 connected to each other. One end of the first support part 1131 is fixed to the base 111, and the other end of the first support part 1131 is connected to one end of the second support part 1132. The other end of the second support part 1132 is fixed to the base 111. The included angle between the first support part 1131 and the second support part 1132 is defined as α, where 60°≤α≤70°. The strength of the second support frame 113 can be improved by connecting the first support part 1131 and the second support part 1132, which in turn helps to increase the stability of the lifting bag 14.

[0053] In one implementation, please refer to Figure 1 The tilting shaft 12 includes a first shaft and a second shaft, both of which are connected to the tilting frame 15. The first and second shafts are spaced apart along a first direction. The first shaft is rotatably mounted on the first support frame 112, and the second shaft is rotatably mounted on the second support frame 113. The connection between the first and second shafts and the tilting frame 15 allows the tilting frame 15 to drive the lifting bag 14 to rotate around the first and second shafts, which enhances the stability of the lifting bag 14's rotation and thus improves the reliability of the tilting mechanism 1's operation.
