Description

Technical Field

[0001] This utility model relates to a vertical water quenching and cooling device, belonging to the field of metallurgical equipment technology. Background Technology

[0002] Metal cooling devices play a vital role in the fields of metal processing and heat treatment, especially in the casting, forging, heat treatment and metallurgical industries. The purpose of cooling is usually to optimize the internal structure of metals, thereby improving their mechanical properties, such as hardness, toughness and wear resistance. In actual production, a combination of air cooling and water quenching is often used, with water quenching being the most critical step.

[0003] Traditional water quenching cooling methods typically involve cooling workpieces by spraying water mist or directly immersing them in a water quenching tank. While this method cools high-temperature workpieces, it has several drawbacks. For example, traditional water quenching results in uneven cooling, especially for complex-shaped or large workpieces. Uneven water flow distribution can lead to overcooling in some areas while undercooling in others. Secondly, the cooling time is uneven due to the workpiece's movement speed, resulting in imprecise cooling rate control. Furthermore, temperature variations and waste of the cooling medium are also potential problems in traditional water quenching; as the water temperature rises during cooling, the cooling efficiency gradually decreases.

[0004] Therefore, it is necessary to design a new type of vertical water quenching cooling device that can effectively cool the workpiece multiple times, avoid uneven cooling time due to the influence of the moving speed, thus affecting the cooling effect, and prevent the cooling efficiency from gradually decreasing due to the rise in water temperature during the cooling process, so as to meet the requirements of high efficiency and stability in the water quenching cooling process. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a vertical water quenching cooling device with high cooling efficiency and stable movement.

[0006] To achieve the above objectives, this utility model provides a vertical water quenching cooling device, comprising a spray tower and a quenching tank; the spray tower includes an inlet spray tower and an outlet spray tower; the inlet spray tower and the outlet spray tower are respectively installed at both ends of the top of the quenching tank, and the internal channels of the inlet spray tower and the outlet spray tower are provided with spray heads evenly distributed in position; the quenching tank includes a submerged roller filled with a cooling medium and an adjusting motor installed on the outer wall of the quenching tank and connected to the axis of the submerged roller, and the circumference of the submerged roller is tangent to the center line of the internal channel of the spray tower.

[0007] The spray head is configured with multiple different spray directions.

[0008] The outer wall of the spray tower is provided with a cooling medium injection port.

[0009] The outer wall of the spray tower is equipped with an inspection window.

[0016] By adopting the above technical solution, the vertical water quenching cooling device of this utility model, through the setting of a submerged roller with a cooling effect in the quenching tank, can not only control the state of the workpiece in the quenching tank, but also cool the workpiece again through the submerged roller. At the same time, combined with the cooling channel of the spray tower, it ensures full contact with the cooling medium, thereby enhancing the cooling effect. Furthermore, the uniformly distributed spray heads inside the spray tower can effectively spray the cooling medium, ensuring rapid and uniform cooling of the surface of the quenched workpiece, reducing temperature difference and internal stress.

[0019] Figure 3 This is a top view of the present invention. Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-3As shown, this utility model discloses a vertical water quenching cooling device, comprising a spray tower 1 and a quenching tank 2. The spray tower 1 includes an inlet spray tower 11 and an outlet spray tower 12. The inlet spray tower 11 and the outlet spray tower 12 are respectively installed at both ends of the top of the quenching tank 2. The internal channels of the inlet spray tower 11 and the outlet spray tower 12 are equipped with spray heads 15 evenly distributed in position. The quenching tank 2 includes a submerged roller 21 filled with cooling medium and an adjusting motor 27 installed on the outer wall of the quenching tank 2 and connected to the axis of the submerged roller 21. The circumference of the submerged roller 21 is tangent to the center line of the internal channel of the spray tower 1. By rationally designing the structure of the spray tower 1 and the quenching tank 2, the cooling efficiency and equipment stability are significantly improved. The evenly distributed multi-directional spray heads 15 inside the inlet spray tower 11 and the outlet spray tower 12 can precisely control the spraying of the cooling medium, ensuring uniform cooling of the workpiece surface, thereby reducing thermal stress and deformation.

[0022] The spray head 15 is multiple and sprays in different directions. The design of multiple spray heads 15 can be flexibly adjusted according to the cooling requirements of different workpieces. For example, by changing the direction, flow rate or spraying method of the spray head 15, the cooling effect can be adapted to workpieces of different shapes, sizes or materials, thereby improving the process adaptability of the equipment.

[0023] The outer wall of the spray tower 1 is provided with a cooling medium inlet 13, which can conveniently replenish the cooling medium to the spray tower 1 system, ensuring that the system always maintains a sufficient supply of cooling liquid during operation and avoiding insufficient cooling medium from affecting the cooling effect. This can maintain the high-efficiency cooling performance of the spray tower 1 and ensure that the workpiece is cooled evenly and continuously throughout the entire cooling process.

[0024] The outer wall of the spray tower 1 is equipped with an inspection window 14, allowing personnel to easily access the interior of the spray tower 1 for routine inspections, cleaning, and maintenance, reducing the complexity of disassembling the equipment. This allows for the timely detection and resolution of problems such as clogged spray heads 15, damaged pipes, or impaired cooling medium flow, ensuring the normal operation of the spray tower 1. Furthermore, due to the design of the inspection window 14, personnel can directly troubleshoot and repair problems without disassembling a large amount of external structure or equipment. This significantly reduces downtime and maintenance time, improving production efficiency and overall equipment availability.

[0025] An overflow port 22 is provided on the outer wall near the top of the quenching tank 2. The overflow port 22 effectively controls the water level of the cooling medium in the quenching tank 2, preventing excessive water level from causing coolant overflow or leakage. Simultaneously, by controlling the water level of the cooling medium, it ensures that the cooling medium can evenly cover the workpiece. Furthermore, by continuously overflowing the excess cooling medium and allowing the normal cooling medium to continuously flow into the quenching tank 2, a good cooling environment is maintained in the quenching tank 2, providing a stable cooling effect. In addition, during the cooling process, the cooling medium may expand due to increased temperature or increased external water input. The overflow port 22 can automatically discharge excess cooling medium, preventing the quenching tank 2 from overflowing, and also helps to remove any impurities or contaminants that may be generated within the quenching tank 2.

[0026] The outer wall of the quenching tank 2 is also equipped with a guide pipe 23 to guide the cooling medium flowing out of the overflow port 22, ensuring it is discharged along a predetermined path. This prevents disorderly flow or splashing of the liquid, thereby reducing the risk of environmental pollution and equipment damage. This helps maintain a clean working environment and prevents the cooling medium from corroding or polluting equipment or the ground. Additionally, the guide pipe 23 can guide the cooling medium flowing out of the overflow port 22 to the system storage tank, enabling the reuse of the cooling medium. By recovering the coolant, the consumption of the cooling medium can be reduced, operating costs lowered, the system's energy efficiency improved, and environmental protection goals supported.

[0027] The flow guiding pipes 23 are multiple, which reduces the risk of a single pipe carrying too much flow and minimizes the impact on the overall cooling effect if any pipe in the system becomes blocked or malfunctions. If one flow guiding pipe 23 malfunctions, the other pipes can still continue to operate, ensuring stable system operation and reducing downtime and maintenance costs.

[0028] The bottom of the quenching tank 2 is provided with a drain outlet 24 to effectively drain impurities, dirt, or waste liquid deposited in the quenching tank 2, keeping the cooling medium clean. This helps prevent impurities from accumulating in the coolant, thereby ensuring the continuity and uniformity of the cooling effect and avoiding clogging of the spray head 15 or degradation of the cooling medium performance.

[0029] The outer wall of the quenching tank 2 is also provided with a drain and cleaning window 26, which provides a convenient channel for inspecting and cleaning sediments, dirt, or impurities inside the tank. Workers can directly enter the tank through the window to clean accumulated dirt or sediment, preventing coolant contamination or reduced cooling efficiency due to dirt buildup, thereby extending the equipment's service life and maintaining high-efficiency cooling performance.

[0030] The regulating motor 27 is equipped with an auxiliary support 25, which provides additional support for the regulating motor 27 and ensures smoother rotation of the submerged roller 21, reducing displacement or shaking of the motor due to vibration or load during operation. This helps maintain the stability of the motor during operation, thereby avoiding motor damage, premature wear, or decreased working efficiency caused by vibration.

[0031] In actual production, the workpiece enters the inlet spray tower 11 through a transmission device. Inside the tower, multiple spray heads 15 evenly spray cooling medium over the workpiece area, which is the first cooling step. Then, the workpiece enters the quenching tank 2 and comes into contact with the cooling medium in the tank, which is the second cooling step. Next, it comes into contact with the submerged roller 21 filled with cooling medium. The motor 27 is adjusted to drive the submerged roller 21 to ensure a stable movement speed of the workpiece and avoid uneven cooling time due to the movement speed, which would affect the cooling effect. This is the third cooling step. Finally, the workpiece passes through the outlet spray tower 12 with spray heads 15 to complete the fourth cooling step.

[0032] By adopting the above technical solution, the vertical water quenching cooling device of this utility model, by setting a submerged roller 21 with a cooling effect in the quenching tank 2, can not only control the state of the workpiece in the quenching tank 2, but also cool the workpiece again through the submerged roller 21. At the same time, combined with the cooling channel of the spray tower 1, it ensures full contact with the cooling medium, thereby enhancing the cooling effect. Furthermore, the spray heads 15 evenly distributed inside the spray tower 1 can effectively spray the cooling medium, ensuring rapid and uniform cooling of the surface of the quenched workpiece, reducing temperature difference and internal stress. In addition, by setting an adjustable motor 27, the transmission speed of the workpiece can be adjusted according to different cooling requirements, making the cooling process more flexible and precise.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
