Description
Technical Field
[0001] This utility model relates to the field of metallurgical production, and in particular to an irregularly shaped crystallizer. Background Technology
[0002] Crystallization, as an important unit operation in chemical engineering, is widely used in many fields such as pharmaceuticals, metallurgy, food, and materials. The crystallizer is the core equipment for realizing the crystallization process, and its performance directly affects product quality, production efficiency, and production costs.
[0003] With the increasing demand for steel materials from industries such as construction, machinery manufacturing, and automobiles, the scale of steel production continues to expand. As a key link in steel production, continuous casting technology places increasingly higher demands on the performance of the crystallizer. The crystallizer needs to be able to improve the quality of the cast billet, production efficiency, and the operating rate of the continuous casting machine to meet the needs of large-scale, high-quality steel production.
[0004] Existing equipment mostly cools and crystallizes high-temperature liquid metal directly through a cooling mechanism. This not only causes friction between the molten metal and the crystallizer wall during solidification and contraction, resulting in surface cracks and reducing the appearance quality and subsequent processing performance of the cast billet, but also causes the billet shell to adhere to the crystallizer wall, leading to defects in the cast billet. In severe cases, it can even cause steel leakage accidents, resulting in production interruptions and equipment damage. Therefore, we propose an irregularly shaped crystallizer to solve the above problems. Utility Model Content

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This utility model, by setting up a vibration component, specifically by turning on motor two to drive several fixed blocks to rotate, enables the crystallization box to vibrate continuously during the cooling and crystallization process of high-temperature liquid metal. This not only avoids surface cracks and improves the appearance quality and subsequent processing performance of the billet, but also prevents steel leakage accidents caused by the billet shell sticking to the crystallization box wall, which could lead to production interruption and equipment damage.
[0017] 2.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] Example 1, such as Figure 1-7As shown, an irregularly shaped crystallizer includes a base 1, a heat dissipation box 11 fixedly connected to the center of the top of the base 1, a plurality of heat dissipation fins 12 fixedly connected to the outer surface of the heat dissipation box 11, a crystallization box 13 fixedly connected to the inner wall of the top of the heat dissipation box 11, a cooling mechanism 14 provided inside the heat dissipation box 11, a discharge assembly 2 provided inside the heat dissipation box 11, and a vibration assembly 3 provided inside the heat dissipation box 11.
[0028] The aforementioned cooling mechanism 14 includes cooling water pipes, a water pump, a water tank, a temperature sensor, valves, and a filter. The water pump draws coolant from the water tank and delivers it through pipes to the cooling water pipes inside the crystallizer wall. The coolant flows in the cooling water pipes, exchanging heat with the crystallizer wall, absorbing heat transferred from the high-temperature molten metal, thus lowering the crystallizer wall temperature. After absorbing heat, the coolant temperature rises and flows back to the water tank. After further cooling (e.g., through a heat dissipation device), it is pumped back to the cooling water pipes, forming a cyclical cooling process. Simultaneously, the temperature sensor monitors the temperature in real time and feeds the signal back to the control system. The control system, based on a set temperature range, adjusts the valve opening to control the coolant flow rate and pressure, thereby achieving precise control of the cooling intensity and ensuring that the molten metal inside the crystallizer solidifies at a predetermined speed and in a predetermined manner.
[0029] Specifically, in order to avoid surface cracks during the cooling and crystallization of high-temperature liquid metal, see [reference needed]. Figure 4 and Figure 5 In this embodiment, the vibration component 3 includes a rotating shell 31, and the inner wall of the heat dissipation box 11 is provided with a sliding groove. The top outer surface of the rotating shell 31 is slidably connected to the inner wall of the sliding groove. The inner wall of the heat dissipation box 11 is rotatably connected with four rotating shafts 33, and the four rotating shafts 33 are arranged in a circular array with the center of the heat dissipation box 11 as the axis.
[0030] Further reading Figure 5 In this embodiment, a fixing plate 32 is fixedly connected to the inner wall of the heat sink 11, a second motor 321 is fixedly connected to the top of the fixing plate 32, a rotating shaft 322 is fixedly connected to the output end of the second motor 321, an internal gear ring 311 is fixedly connected to the inner surface of the rotating shell 31, a gear 323 is meshed with the end of the internal gear ring 311 away from the inner wall of the heat sink 11, and the bottom of the gear 323 is fixedly connected to the top of the rotating shaft 322.
[0031] Further reading Figure 5 In this embodiment, an external gear ring 312 is fixedly connected to the outer surface of the rotating shell 31, and a gear 331 is fixedly connected to the bottom of each of the four rotating shafts 33. The end of each of the four gears 331 near the center of the heat sink 11 is meshed with the outer surface of the external gear ring 312.
[0032] During implementation, the motor 321 is turned on to drive the rotating shaft 322 to rotate. When the rotating shaft 322 rotates, it will drive the rotating shell 31 to rotate in the inner wall of the heat sink 11 through the inner gear ring 311. When the rotating shell 31 rotates, it will drive the outer gear ring 312 to rotate.
[0033] Further reading Figure 6 and Figure 7 In this embodiment, several fixing blocks 34 are fixedly connected to the outer surface of the rotating shaft 33, and three striking blocks 341 are slidably connected to the inner wall of the fixing blocks 34. The three striking blocks 341 are arranged in a circular array with the rotating shaft 33 as the axis. A spring 342 is fixedly connected to one end of the striking block 341 near the rotating shaft 33, and the end of the spring 342 near the rotating shaft 33 is fixedly connected to the inner wall of the fixing block 34.
[0034] During implementation, the rotation of the external gear ring 312 drives the four gears 331 to rotate. The rotation of the gears 331 drives the corresponding rotating shaft 33 to rotate within the inner wall of the heat sink 11. Simultaneously, the rotation of the rotating shaft 33 drives several fixed blocks 34 to rotate. During the rotation of the fixed blocks 34, the end of the striking block 341 furthest from the rotating shaft 33 contacts the surface of the crystallization box 13, striking it and causing it to vibrate. When the striking block 341 contacts the surface of the crystallization box 13, it pushes it to slide closer to the rotating shaft 33. As the striking block 341 slides, it compresses the spring 342, causing it to vibrate. When the striking block 341 separates from the surface of the crystallization box 13, the deformed spring 342 will push the striking block 341 to slide back to its original position away from the rotating shaft 33 due to the elastic force. By driving several fixed blocks 34 to rotate continuously, the crystallization box 13 can continuously vibrate during the cooling and crystallization process of the high-temperature liquid metal. This not only reduces the friction between the molten metal and the inner wall of the crystallization box when the molten metal solidifies and shrinks, thus avoiding cracks on its surface and improving the appearance quality and subsequent processing performance of the billet, but also avoids the occurrence of steel leakage accidents caused by the billet shell sticking to the wall of the crystallization box, resulting in production interruption and equipment damage.
[0035] Example 2: This example is based on Example 1, with the addition of a discharge component.
[0036] Specifically, in order to achieve the goal of quickly removing the billet from the inside of the device, see [reference needed]. Figure 2 and Figure 3 In this embodiment, the discharge assembly 2 includes a motor 21, the bottom of which is fixedly connected to the top of the base 1, and a rotating shaft is fixedly connected to the output end of the motor 21. A rotating rod 22 is rotatably connected to the inner wall of the heat dissipation box 11.
[0037] Further reading Figure 3In this embodiment, both the outer surface of the rotating rod 22 and the outer surface of the rotating shaft are fixedly connected to a pulley 211, and the outer surfaces of the two pulleys 211 are connected to a belt 212 for transmission. The outer surface of the rotating rod 22 is threaded.
[0038] Further reading Figure 3 In this embodiment, the inner wall of the heat dissipation box 11 and the bottom inner wall of the crystallization box 13 are slidably connected to a slide rod 23. The inner wall of the slide rod 23 is threadedly connected to the outer surface of the rotating rod 22. A push plate 231 is fixedly connected to the top of the slide rod 23. The outer surface of the push plate 231 is slidably connected to the inner wall of the crystallization box 13.
[0039] During implementation, motor 21 is turned on, driving belt pulley 211 to rotate. When belt pulley 211 rotates, it drives another belt pulley 211 to rotate via belt 212, which in turn drives rotating rod 22 to rotate clockwise. As rotating rod 22 rotates clockwise, it drives sliding rod 23 to slide upward. As sliding rod 23 slides upward, it pushes pusher plate 231 to move upward in the inner wall of crystallization box 13, so that the crystallized billet inside crystallization box 13 can be pushed upward out of crystallization box 13. This not only shortens the production cycle of a single billet and allows the crystallizer to carry out the next round of casting operations more quickly, improving the rhythm and efficiency of the entire production process, but also applies the ejection force evenly and steadily, so that the billet is subjected to more balanced force during demolding, reducing defects such as billet deformation and cracks caused by uneven force, and ensuring the appearance and internal quality of the billet.
[0040] The working principle of this utility model is as follows: When the device is needed, high-temperature liquid metal is first injected into the crystallization box 13, and cooled and crystallized by the cooling mechanism 14. Simultaneously, motor 321 is turned on to drive the rotating shaft 322 to rotate. When the rotating shaft 322 rotates, it drives the rotating shell 31 to rotate within the heat sink 11 via the internal gear ring 311. The rotating shell 31 rotates, driving the external gear ring 312 to rotate. Simultaneously, the external gear ring 312 rotates, driving four gears 331 to rotate. The rotation of gears 331 drives the corresponding rotating shaft 33 to rotate within the heat sink 11. Simultaneously, the rotating shaft 33 rotates, driving several fixed blocks 34 to rotate. During the rotation of the fixed blocks 34, the end of the striking block 341 furthest from the rotating shaft 33 contacts the surface of the crystallization box 13, striking the crystallization box 13. It generates vibration. When the striking block 341 contacts the surface of the crystallization box 13, it pushes the striking block 341 to slide towards the direction of the rotating shaft 33. When the striking block 341 slides, it squeezes the spring 342 and causes it to deform. When the striking block 341 separates from the surface of the crystallization box 13, the deformed spring 342 will push the striking block 341 to slide away from the rotating shaft 33 and return to its original position due to the elastic force. By driving several fixed blocks 34 to rotate continuously, the crystallization box 13 can continuously vibrate during the cooling and crystallization process of high-temperature liquid metal. This not only reduces the friction between the molten metal and the inner wall of the crystallization box when the molten metal solidifies and shrinks, thus avoiding cracks on its surface and improving the appearance quality and subsequent processing performance of the billet, but also avoids the occurrence of steel leakage accidents caused by the billet shell sticking to the wall of the crystallization box, resulting in production interruption and equipment damage.
[0041] After crystallization is complete, motor 21 is turned on to drive pulley 211 to rotate. When pulley 211 rotates, it drives another pulley 211 to rotate via belt 212, which in turn drives rotating rod 22 to rotate clockwise. As rotating rod 22 rotates clockwise, it drives sliding rod 23 to slide upward. As sliding rod 23 slides upward, it pushes pusher 231 to move upward in the inner wall of crystallization box 13, so that the crystallized billet inside crystallization box 13 can be pushed upward out of crystallization box 13. This not only shortens the production cycle of a single billet and allows the crystallizer to carry out the next round of casting operations more quickly, improving the rhythm and efficiency of the entire production process, but also applies the ejection force evenly and steadily, so that the billet is subjected to more balanced force during demolding, reducing defects such as billet deformation and cracks caused by uneven force, and ensuring the appearance and internal quality of the billet.
