Description

Technical Field

[0001] This utility model relates to the field of casting coil production technology, and in particular to a rapid cooling device for casting coils. Background Technology

[0002] Casting coils are a type of coiled product manufactured using casting processes. The manufacturing process involves pouring molten metal into a mold and allowing it to cool and solidify to form a solid coil. The main purpose of the cooling process is to lower the temperature of the casting coil from its high-temperature state to achieve equilibrium with the ambient temperature, preventing problems such as deformation caused by high temperatures.

[0003] In existing casting technologies, the cooling method for casting coils typically involves directly immersing them in a cooling tank. While simple and easy to implement, this method has several drawbacks in practice. First, the cooling tank is usually quite deep, requiring the coil to be completely submerged during cooling, making it extremely inconvenient to remove after cooling and consuming significant manpower and time. Second, coils piled up in the cooling tank are prone to collisions and friction, leading to product quality issues. Utility Model Content

The other end of the connecting rod is hinged to the middle of the positioning plate.

[0007] As a further description of the above technical solution, the refrigeration mechanism includes a semiconductor refrigeration chip assembly, a temperature-conducting plate, and a heat sink. The semiconductor refrigeration chip assembly is installed on the upper side wall of the heat exchange box, and the temperature-conducting plate is fixedly connected to the upper inner wall of the heat exchange box.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-6This utility model provides a rapid cooling device for casting drums, including a cooling pool 1. An L-shaped bracket 2 is fixedly connected to the rear outer wall of the cooling pool 1. A cylinder 21 is installed on the upper outer wall of the L-shaped bracket 2. The output shaft of the cylinder 21 passes through the upper outer wall of the L-shaped bracket 2 and is fixedly connected to a T-shaped lifting frame 3. Multiple hollow hanging rods 4 are fixedly connected to the front outer wall of the T-shaped lifting frame 3. The output shaft of the cylinder 21 can drive the T-shaped lifting frame 3 to rise and fall. When it falls, the drum on the hanging rods 4 can be rapidly cooled in the cooling pool 1. After cooling, the drum can be lifted to facilitate removal. A heat exchange box 5, a first water pump 11, and a second water pump 12 are installed on one outer wall of the cooling pool 1. The bottom wall of the cooling pool 1 has a drain outlet 13. The input end of the first water pump 11 is connected to the drain outlet 13 through a water pipe, and the output end is connected to the heat exchange box 5 through a water pipe. The input end of the second water pump 12 is connected to the heat exchange box 5 through a water pipe, and the output end is connected to the inside of the cooling pool 1 through a water pipe. The first water pump 11 can draw water from the cooling pool 1 and transport it to the heat exchange box 5 for cooling. After cooling, the water is drawn out by the second water pump 12 and transported to the cooling pool 1, so as to achieve the purpose of circulating and cooling the cooling water in the cooling pool 1, ensuring that the water temperature in the cooling pool 1 is always kept at a low level, thereby significantly improving the cooling efficiency. The hanging rod 4 is equipped with a positioning mechanism 6, and the heat exchange box 5 is equipped with a refrigeration mechanism 7.

[0025] Specifically, such as Figure 3 and Figure 4 As shown, a rapid cooling device for casting rolls includes a positioning mechanism 6 comprising a slip ring 61, a bidirectional screw 62, a handwheel 63, a positioning plate 64, and a connecting rod 65. Two symmetrically distributed slip rings 61 are slidably arranged inside the hanging rod 4. A bidirectional screw 62 is rotatably mounted on the rear inner wall of the hanging rod 4. The front end of the bidirectional screw 62 is threaded through the two slip rings 61 and extends to the front of the hanging rod 4, where it is fixedly connected to the handwheel 63. Four positioning plates 64 are arranged around the outer side of the hanging rod 4. Four connecting rods 65 are arranged around the ring wall of the slip rings 61. The other end of the connecting rod 65 is hinged to the middle of the positioning plate 64. Rotating the handwheel 63 can drive the bidirectional screw 62 to rotate. When the bidirectional screw 62 rotates, it can bring the two slip rings 61 closer together. Under the action of the connecting rod 65, the four positioning plates 64 tighten the roll, thereby fixing the roll. When the fixed roll enters the cooling pool 1, it can avoid shaking under tension, thus preventing collisions and friction between rolls and avoiding product defects.

[0026] Specifically, such as Figure 5As shown, a rapid cooling device for casting rolls includes a cooling mechanism 7 comprising a semiconductor cooling chip assembly 71, a temperature-conducting plate 72, and a radiator 73. The semiconductor cooling chip assembly 71 is installed on the upper side wall of the heat exchange chamber 5, and the temperature-conducting plate 72 is fixedly connected to the upper inner wall of the heat exchange chamber 5. The temperature-conducting plate 72 is in contact with the cold side of the semiconductor cooling chip assembly 71, and the radiator 73 is installed on the hot side of the semiconductor cooling chip assembly 71. The semiconductor cooling chip assembly 71 can cool the temperature-conducting plate 72, and the temperature-conducting plate 72 conducts low temperature to the heat exchange chamber 5 to cool the water inside the heat exchange chamber 5. The radiator 73 dissipates heat from the hot side of the semiconductor cooling chip assembly 71 to ensure its normal operation.

[0027] Specifically, such as Figure 3 As shown, a rapid cooling device for casting drums has four guide grooves 41 on the inner ring of the hanging rod 4. The slip ring 61 slides with the guide grooves 41. Under the action of the guide grooves 41, the slip ring 61 will not rotate and can only move in a straight line.

[0028] Specifically, such as Figure 1 As shown, a rapid cooling device for casting drums is provided. Guide rods 22 are slidably inserted on the upper side wall of the L-shaped bracket 2 and on both sides of the cylinder 21. The lower end of the guide rods 22 is fixedly connected to the T-shaped lifting frame 3. When the T-shaped lifting frame 3 is raised or lowered, the guide rods 22 can be raised or lowered along with it, making its movement more stable.

[0029] Specifically, such as Figure 6 As shown, a rapid cooling device for casting drums is provided, wherein a filter screen 131 is installed in the drain outlet 13. The filter screen 131 can filter the circulating cooling water to prevent impurities generated during the drum cooling process from participating in the circulation.

[0030] It should be noted that this utility model is a rapid cooling device for casting drums. In use, the drum is hung on the hanging rod 4, and then the handwheel 63 is turned to drive the bidirectional screw 62 to rotate. When the bidirectional screw 62 rotates, the two slip rings 61 move closer together. Under the action of the connecting rod 65, the four positioning plates 64 tighten the drum, thus fixing it in place. When the fixed drum enters the cooling pool 1, it is prevented from shaking under tension, thus preventing collisions and friction between the drums and avoiding product defects. After all the drums are fixed, the cylinder 21 is activated. The output shaft of the cylinder 21 pushes the T-shaped lifting frame 3 downwards, causing all the drums to be submerged in the cooling water in the cooling pool 1 for cooling. After cooling is completed, the output shaft of the cylinder 21 drives the T-shaped lifting frame 3 upwards. All the drums are raised and then removed one by one. During use, the first water pump 11 can draw water from the cooling pool 1 and transport it to the heat exchange box 5. The semiconductor refrigeration chip group 71 cools the temperature conduction plate 72, which conducts the low temperature to the heat exchange box 5 to cool the water in the heat exchange box 5. The radiator 73 dissipates heat from the hot surface of the semiconductor refrigeration chip group 71 to ensure its normal operation. The radiator 73 is a mature existing technology, and its specific structure and principle will not be described here. After cooling, the water is drawn out by the second water pump 12 and transported to the cooling pool 1 to achieve the purpose of circulating and cooling the cooling water in the cooling pool 1, ensuring that the water temperature in the cooling pool 1 is always kept at a low level, thereby significantly improving the cooling efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
