Description

Technical Field

[0001] This utility model relates to a water-blocking valve for quenching and cooling aluminum profiles, belonging to the technical field of aluminum profile quenching and cooling equipment. Background Technology

[0002] With the improvement of smelting technology, many metal materials need to be cooled after quenching. Quenching and cooling technology refers to the process of heating materials and components to a certain temperature and then cooling them in a predetermined manner and rate to obtain the expected results. In the aluminum profile extrusion process, after the aluminum profile is hot-extruded into shape by an extruder, it needs to undergo quenching and cooling treatment so that its comprehensive technical performance indicators such as hardness and strength can meet the quality requirements of aluminum profile products.

[0003] Currently, there are two methods for cooling aluminum profiles after quenching: air cooling and water cooling. When using air cooling, simply open the valve of the air duct and blow the cold air from the air duct onto the surface of the aluminum profile. However, when using water cooling, the valve of the air duct needs to be closed to prevent the cooling water from flowing back into the fan.

[0004] The current approach involves installing a valve at each air duct opening and connecting these valves in series via a linkage mechanism to achieve synchronized opening and closing. The drawbacks are that it lacks a water-blocking function and has a cumbersome structure.

[0005] Therefore, the research objective of this utility model is to provide a water-blocking valve for quenching and cooling aluminum profiles that has a water-blocking function and a simple structure. Utility Model Content

[0006] To address the shortcomings of the aforementioned technologies, this utility model provides a water-blocking valve for quenching and cooling aluminum profiles. By installing the water-blocking valve on the main air duct between the fan and the air duct, it can not only block water but also has a simpler structure.

[0007] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows:

[0008] A water-blocking valve for quenching and cooling aluminum profiles includes a fan, an air duct, and a water-blocking valve. The fan and the air duct are connected by a main air pipe. The inner side of the main air pipe is provided with a door frame matching the water-blocking valve along its circumference. The water-blocking valve is rotatably connected to the inner side of the main air pipe. A cylinder that drives the water-blocking valve to open or close is connected to one side of the water-blocking valve. A protruding water-blocking plate is also provided at the bottom of the inner side of the main air pipe. The water-blocking plate is located on the side of the water-blocking valve near the fan. A drain pipe is connected to the outer side of the main air pipe. The inlet of the drain pipe is located between the water-blocking valve and the water-blocking plate.

[0009] Furthermore, the air duct is configured as a bucket-shaped structure that is wider at the top and narrower at the bottom, and the main air pipe is connected to the bottom of the air duct.

[0010] Furthermore, the top of the water-blocking valve is rotatably connected to the main air duct, and the water-blocking valve is provided with a sealing gasket along its circumference.

[0011] Furthermore, the main body of the cylinder is rotatably connected to the bottom of the main air duct and is located on the side of the water baffle valve near the fan, with the end of its piston rod rotatably connected to the water baffle valve.

[0012] Furthermore, a proportional air valve control switch electrically connected to the cylinder is also provided on the outside of the main air duct.

[0013] The beneficial effects of this utility model are: 1. By blocking the connection between the fan and the air duct through the water-blocking valve, when the water in the air duct is used to water-cool the aluminum profile, the cooling water in the air duct will not flow back into the fan, thus achieving both air cooling and water cooling; 2. Only one valve is set in the main air duct, instead of setting valve plates at each air duct opening, making the structure simpler. Attached Figure Description

[0015] Figure 2 This is one of the partial structural diagrams of this utility model.

[0016] Figure 3 This is the second partial structural diagram of this utility model.

[0017] The components include: 1. Fan, 2. Air duct, 3. Water baffle valve, 4. Main air duct, 5. Door frame, 6. Cylinder, 7. Water baffle plate, 8. Drain pipe, and 9. Proportional air valve control switch. Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-3 Further analysis of this utility model is then conducted.

[0019] like Figure 1-3As shown, a water-blocking valve for quenching and cooling aluminum profiles includes a fan 1, an air duct 2, and a water-blocking valve 3. The fan 1 and the air duct 2 are connected by a main air pipe 4. The inner side of the main air pipe 4 is provided with a door frame 5 that matches the water-blocking valve 3 along its circumference. The water-blocking valve 3 is rotatably connected to the inner side of the main air pipe 4. A cylinder 6 is connected to one side of the water-blocking valve 3 to drive it to open or close. A raised water-blocking plate 7 is also provided at the bottom of the inner side of the main air pipe 4. The water-blocking plate 7 is located on the side of the water-blocking valve 3 near the fan 1. A drain pipe 8 is connected to the outer side of the main air pipe 4. The inlet of the drain pipe 8 is located between the water-blocking valve 3 and the water-blocking plate 7.

[0020] In this embodiment, preferably, the air duct 2 is configured as a bucket-shaped structure that is wider at the top and narrower at the bottom, and the main air pipe 4 is connected to the bottom of the air duct 2.

[0021] In this embodiment, preferably, the top of the water-blocking valve 3 is rotatably connected to the main air duct 4, and the water-blocking valve 3 is provided with a sealing gasket along its circumference to improve the waterproof performance between the water-blocking valve 3 and the door frame 5.

[0022] In this embodiment, preferably, the main body of the cylinder 6 is rotatably connected to the bottom of the main air duct 4 and is located on the side of the water-blocking valve 3 near the fan 1, and the end of its piston rod is rotatably connected to the water-blocking valve 3.

[0023] In this embodiment, preferably, a proportional air valve control switch 9 electrically connected to the cylinder 6 is also provided on the outside of the main air duct 4, which is used to control the opening or closing of the water-blocking valve 3.

[0024] The working principle of this utility model is as follows: When air cooling is used to cool the aluminum profile, the water-blocking valve 3 is opened, and the cold air blown out by the fan 1 is blown into the air duct 2 through the main air pipe 4 to cool the aluminum profile conveyed from the top of the air duct 2. When water cooling is used to cool the aluminum profile, the water-blocking valve 3 is closed, and cooling water is poured into the air duct 2. The traction equipment or conveying equipment transports the aluminum profile to the cooling water in the air duct 2 for water cooling. During water cooling, the water-blocking valve 3 blocks the cooling water in the air duct 2, preventing it from flowing back into the fan 1. Even if a small amount of cooling water seeps in from between the water-blocking valve 3 and the door frame 5, it is blocked by the water baffle 7 and flows out from the drain pipe 8.

[0025] The technical solutions provided in this application have been described in detail above. The embodiments used in this document illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
