Description

Technical Field

[0001] This utility model relates to the field of metal product cooling technology, and more specifically, to a rapid cooling device for heat treatment of metal products. Background Technology

[0002] The metal products industry encompasses the manufacturing of structural metal products, metal tools, containers and metal packaging containers, and stainless steel and similar everyday metal products. With societal progress and technological development, metal products are increasingly widely used in industry, agriculture, and various aspects of daily life, creating ever-growing value for society. Currently, after heat treatment, metal products typically require cooling in containers filled with coolant. This cooling method is slow and inefficient, and the coolant, after heating up, cannot be reused, resulting in resource waste. To address these issues, existing technologies employ circulation pipelines to recycle the coolant. However, in these existing technologies, the liquid flow direction within the coolant container is irregular. Due to this irregular flow, some coolant tends to stagnate in the container for extended periods, leading to a decrease in cooling effectiveness. Utility Model Content

[0026] Example

[0027] Please refer to Figures 1-5This embodiment provides a rapid cooling device for heat treatment of metal products, including a water tank 1 and multiple strip-shaped cooling boxes 2 arranged side by side. One end of any strip-shaped cooling box 2 is connected to an inlet pipe 3, and the other end is connected to an outlet pipe 4. The inlet pipe 3 and the outlet pipe 4 are respectively connected to the two ends of the strip-shaped cooling box 2. A flared tube 5 is provided between the strip-shaped cooling box 2 and the inlet pipe 3. The small-diameter end of the flared tube 5 is connected to the inlet pipe 3, and the large-diameter end of the flared tube 5 is connected to the end of the strip-shaped cooling box 2. By connecting the inlet pipe 3 and the outlet pipe 4 to the two ends of the strip-shaped cooling box 2, the coolant flowing through it flows regularly in a straight line along its extension direction. During the flow, the coolant carries away the heat from the metal product and is quickly discharged along the outlet pipe 4, preventing the problem of some coolant remaining in the cooling box for a long time. Meanwhile, the flared tube 5 in this application allows the liquid to enter the strip-shaped cooling tank 2 uniformly along the end of the tank, further improving the flow stability of the coolant in the flow direction and thus further enhancing the cooling effect. Therefore, this rapid cooling device for heat treatment of metal products enables the coolant to flow regularly, effectively avoiding the problem of reduced cooling effect caused by partial coolant stagnation.

[0028] It should be noted that using a strip-shaped cooling box 2 allows the coolant to flow in a straight line, which can further reduce the problem of increased fluid resistance caused by the inner wall of the strip-shaped cooling box 2, thereby increasing the fluid flow rate and improving the cooling effect while saving energy.

[0029] Please refer to Figure 1 and Figure 2 In addition, this embodiment has multiple cooling boxes, and users can activate different cooling boxes as needed, and can also put different metal products in different cooling boxes as needed, which can improve production efficiency.

[0030] Please refer to Figure 2 and Figure 3 In some embodiments of this example, the end of the strip-shaped cooling box 2 located at the flared tube 5 is provided with evenly spaced through holes 6, and the large-diameter end of the flared tube 5 is covered by the through holes 6. The through holes 6 allow the coolant to enter evenly along the end of the strip-shaped cooling box 2, preventing excessive concentration of coolant in a certain area and further ensuring the flow stability of the coolant. The through holes 6 covering the large-diameter end of the flared tube 5 allow the coolant to enter the strip-shaped cooling box 2 smoothly, ensuring full utilization of the coolant and maximizing the cooling effect. Simultaneously, the fit between the flared tube 5 and the end of the strip-shaped cooling box 2 also enhances the structural stability of the entire cooling device.

[0031] Please refer to Figure 2 and Figure 3 Specifically, in this embodiment, the through hole 6 is a strip-shaped structure.

[0032] Please refer to Figure 1 and Figure 2 and Figure 4 In some embodiments of this example, a control valve 7 is connected in series on any inlet pipe 3. Preferably, the control valve 7 is a flow valve. The control valve 7 allows the operator to easily control the inflow of coolant, thereby achieving precise control of the cooling process. In actual operation, when it is necessary to adjust the cooling rate or pause cooling, this can be achieved simply by adjusting the opening degree of the control valve 7 or completely closing the control valve 7. This not only improves the flexibility of the cooling process but also facilitates the operator to adjust the cooling effect in real time. In addition, the use of a flow valve enhances the safety performance of the entire cooling device. In case of emergency or maintenance, the coolant supply can be quickly cut off to ensure the safety of the operator.

[0033] In some embodiments of this utility model, the control valve 7 is connected to a control unit, and a temperature sensor is installed inside any strip-shaped cooling box 2. The temperature sensor is connected to the control unit.

[0034] This control unit can receive data from temperature sensors in real time, thus accurately monitoring the temperature within the cooling chamber. Operators can use the control unit to understand the current cooling progress and effect, further enhancing the controllability and intelligence of the cooling process. Simultaneously, the control unit can automatically adjust the opening degree of control valve 7 according to preset cooling programs or operator commands, achieving a more precise and stable cooling rate. Specifically, the temperature sensor transmits the monitored temperature information to the control unit. Upon receiving the temperature information, the control unit controls the opening or closing of the corresponding control valve 7 or adjusts its opening degree according to the preset program. Therefore, this intelligent control method not only improves cooling efficiency but also effectively avoids problems such as uneven cooling or overcooling caused by improper manual operation, thereby ensuring the quality and stability of the heat treatment of metal products.

[0035] In this embodiment, each inlet pipe 3 is connected to a main pipe 8 via a common inlet pipe 3. Multiple inlet pipes 3 share the same main pipe 8, and a delivery pump 9 is connected in series on the main pipe 8. The delivery pump 9 ensures that the cooling liquid is delivered to each inlet pipe 3 at a constant flow rate and pressure. By adjusting the speed or operating state of the delivery pump 9, the supply rate of the cooling liquid can be precisely controlled, thereby further refining the control of the cooling process. The shared main pipe 8 simplifies the piping layout of the cooling device, reduces manufacturing costs, and facilitates subsequent maintenance and upkeep.

[0036] It is worth noting that the water tank 1 is equipped with a filter plate 12, which divides the water tank 1 into a first chamber 10 and a second chamber 11. The first chamber 10 is connected to the outlet pipe 4, and the second chamber 11 is connected to the inlet pipe 3. After one cooling cycle, the coolant first passes through the first chamber 10 for preliminary impurity sedimentation, then passes through the filter plate 12 for filtration, and then passes through the second chamber 11 to re-enter the main pipe 8 and the inlet pipe 3 for cooling cycle. The presence of the filter plate 12 effectively prevents impurities and particles in the coolant from causing blockage or wear on the pipes and components such as the control valve 7 connected in series on the pipes, thus extending the service life of the cooling device. In this way, cooling efficiency is guaranteed while also ensuring the durability and ease of maintenance of the device.

[0037] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 In some embodiments of this example, any strip-shaped cooling box 2 is provided with a perforated storage basket 13, and adjacent perforated storage baskets 13 are connected by connecting plates 14. Metal products can be neatly placed in the perforated storage baskets 13, which not only facilitates the uniform penetration and flow of the cooling liquid, improving cooling efficiency, but also facilitates the handling and management of metal products. The use of connecting plates 14 further enhances the structural stability between the perforated storage baskets 13, preventing the perforated storage baskets 13 from shifting or tipping over due to liquid flow or improper operation during the cooling process. In addition, both the perforated storage baskets 13 and the connecting plates 14 can be made of corrosion-resistant, high-temperature resistant, and high heat transfer rate materials to meet the needs of various cooling processes, further improving the practicality and durability of the cooling device. Specifically, in this embodiment, the perforated storage basket 13 is actually formed by evenly spaced openings (not shown in the figure) on the frame. In particular, large flow ports (not shown in the figure) are directly opened at both ends of the hollow storage basket 13 (specifically at the two ends near the cooling box) so that the fluid flowing through these ports will experience minimal resistance, which can greatly reduce the interference of the two ends of the hollow storage basket 13 on the fluid flow direction.

[0038] Please refer to Figure 1 and Figure 2In this embodiment, multiple strip-shaped cooling boxes 2 are disposed on the outer top surface of the water tank 1. At least one lifting mechanism is provided between any connecting plate 14 and the water tank 1. The lifting mechanism includes a hydraulic push rod 15, the cylinder of which is disposed on the water tank 1, and the piston rod of which is connected to the corresponding connecting plate 14. By precisely controlling the extension and retraction of the piston rod, the hydraulic push rod 15 can smoothly adjust the height of the connecting plate 14 and the hollow storage basket 13, so as to separate the metal products in the hollow storage basket 13 from the coolant, making it convenient to put in and take out the metal products, and also serving as a filter. The hydraulic push rod 15 has good load-bearing capacity and durability, and can bear the weight of the storage basket and the metal products therein, maintaining stable performance during long-term use. In addition, driven by the lifting mechanism, the connecting plate 14 and the storage basket can be easily raised and lowered, so that the metal products in the hollow storage basket 13 can be adjusted in the cooling position within the cooling box, improving cooling flexibility.

[0039] It is worth further explaining that the water tank 1 in this embodiment is equipped with a cooler (not shown in the figure), which can quickly cool the coolant so that when the coolant re-enters the cooling tank, the heat exchange efficiency is accelerated under the action of temperature difference, thereby improving the cooling efficiency of metal products.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
