Description

Technical Field

[0001] The utility model relates to the technical field of quenching pools, in particular to a quenching pool for aluminum alloy plates using dynamic circulation of cooling water. Background Art

[0002] In the processing of aluminum alloy plates, quenching is a crucial process, which directly affects the final performance and quality of the plates. The traditional quenching method is usually to immerse the aluminum alloy plates directly in a quenching tank filled with quenching liquid, and the rapid cooling of the quenching liquid allows the plates to achieve the required metallographic structure and mechanical properties. However, traditional quenching tanks mostly rely on natural convection or simple mechanical stirring to achieve the circulation and cooling of the quenching liquid, but these methods often have problems such as slow cooling speed, poor uniformity, and high energy consumption. These problems are particularly prominent when processing large-sized or high-demand aluminum alloy plates, and it is difficult to meet the high-quality and high-efficiency requirements of modern industrial production. Especially when the plates are thick or complex in shape, local overcooling is prone to occur, which affects the overall performance of the plates.

[0003] Currently, the operating model of aluminum alloy plate quenching tanks leaves much to be desired. Traditional quenching tanks rely heavily on manual labor or simple lifting equipment for loading and unloading aluminum alloy plates. Manual operation is not only labor-intensive but also difficult to precisely control the speed and position of the aluminum alloy plates as they are immersed in the cooling water. This can easily affect quenching uniformity due to deviations in the placement of the aluminum alloy plates. While simple lifting equipment can reduce labor costs, it lacks stable lifting and adjustment capabilities. During the insertion and removal of aluminum alloy plates, shaking can easily cause the aluminum alloy plates to collide with the tank wall, resulting in plate deformation or surface damage. Utility Model Content

A blowing device is provided at the bottom of the quenching pool body, and the blowing device is used to spray gas into the quenching pool. A gas generating device for transporting gas to the blowing device is also provided on the outside of the quenching pool body. When in use, the gas generating device passes gas into the blowing device and sprays it out. Bubbles are formed when the gas enters the quenching liquid, and the bubbles burst during the upward movement, forming a stirring effect, thereby accelerating the cooling of the aluminum alloy plates.

The blowing pipes are densely provided with blowing ports for gas ejection. The blowing pipes are also connected to a main pipeline, one end of which extends to the outside of the quenching pool body and is connected to the gas generating device.

[0008] Preferably, a cooling device is further provided outside the quenching tank body, and the cooling device is used to cool the quenching liquid in the quenching tank body.

[0009] Preferably, the cooling device includes a first connecting pipe and a second connecting pipe, one end of the first connecting pipe is connected to a position near the bottom of one side of the quenching pool body, and one end of the second connecting pipe is connected to a position near the top of the other side of the quenching pool body, and the other ends of the first connecting pipe and the second connecting pipe are connected to a heat dissipation pipe.

[0010] Preferably, the heat dissipation pipe is in an "S" shape, and the heat dissipation pipe is evenly provided with multiple layers, and a plurality of heat dissipation fins capable of conducting heat are also provided on the outside of the heat dissipation pipe, and there is a space for air flow between each heat dissipation fin.

[0011] Preferably, the cooling device also includes a pump body and a cooling fan. The pump body is arranged on the second connecting pipe. The pump body is used to transport the quenching liquid in the quenching pool body to the heat dissipation pipe. The heat of the quenching liquid is transferred to the heat sink through the heat dissipation pipe. A cooling fan is also fixed on the heat sink. The cooling fan makes the air flow and takes the heat out of the heat sink.

[0012] Preferably, the lifting device includes a support member and a support platform, and driving devices are fixed on both sides of the top of the support member. The driving device is used to move the support platform up and down, place the aluminum alloy plate into the quenching pool body or lift the aluminum alloy plate in the quenching pool body to its top. A conveying roller is also rotatably provided on the support platform, and a mounting frame is placed on the conveying roller. The aluminum alloy plate is placed on the mounting frame and fixed by a fixing device.

[0013] Preferably, the driving device includes a rotating shaft and a rotating driving member. The rotating shaft is movably arranged on the top of the support member. At least one set of sprockets is symmetrically installed on the rotating shaft. A chain is engaged on the sprocket. One end of the chain is connected to a connecting rod, and the connecting rod is connected to the support platform. The other end of the chain is also connected to a counterweight device for counterweighting. The rotating driving member is used to drive the rotating shaft to rotate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the cooling water dynamic circulation aluminum alloy plate quenching pool has a reasonable structure and has the following advantages:

[0015] (1) The present invention is also equipped with a lifting device, which not only simplifies the quenching process of the aluminum alloy plate but also improves the safety of the operation. The conveying roller in the lifting device is provided with a mounting frame for placing and fixing the aluminum alloy plate. Through the precise control of the lifting device, the aluminum alloy plate can be easily sent into or removed from the quenching tank body, which greatly improves production efficiency and operational convenience, and solves the problem of shaking when placing and removing the workpiece in the traditional way.

[0016] (2) This application installs an air blowing device at the bottom of the quenching tank body. The device includes air blowing pipes arranged vertically and horizontally, and air blowing ports are densely distributed on the air blowing pipes. This design allows the blown gas to form a large number of bubbles in the quenching liquid.

The air blowing pipes arranged vertically and horizontally further enhance the stirring effect, ensuring that the aluminum alloy plate can be cooled quickly and evenly.

[0017] (3) The present application also provides a cooling device on the outside of the quenching pool body. Since the quenching liquid absorbs the heat of the aluminum alloy plate and its temperature rises, the cold water is in the lower layer of the hot water. The pump body is started, and the pump body draws the upper layer of hot water into the heat dissipation pipe. Since the heat dissipation pipe is arranged in an "S" shape, the heat is transferred to the heat sink. Due to the special shape of the heat dissipation pipe and the heat sink, the heat conduction effect is better. Then, by starting the heat dissipation fan, the heat dissipation fan causes air to flow, thereby taking out the heat on the heat sink and the heat dissipation pipe. Subsequently, the cooled quenching liquid enters the quenching pool body from the bottom of one end of the quenching pool body, thereby realizing the dynamic recycling of the quenching liquid.

[0025] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1-6 As shown, the utility model provides: a cooling water dynamic circulation aluminum alloy plate quenching pool, including a quenching pool body 1, the quenching pool body 1 is constructed of corrosion-resistant materials, such as stainless steel or special alloys, and the surface is anti-corrosion treated to extend the service life. The quenching pool body 1 is used to store quenching liquid for rapid cooling of products. The bottom of the quenching pool body 1 is provided with a blowing device 3, and the blowing device 3 is used to spray gas into the quenching pool body 1. The outside of the quenching pool body 1 is also provided with a gas generating device for transporting gas to the blowing device 3. The gas generating device uses an efficient and energy-saving gas generator, such as a compressed air system or a blower, to ensure the provision of a stable and pure gas flow. During use, the gas generating device passes the gas into the blowing device 3 and sprays it out. The gas enters the quenching liquid to form bubbles, which will burst during the upward movement, forming a stirring effect, thereby accelerating the cooling of the aluminum alloy plate. The quenching pool body 1 is buried underground, and the inlet of the quenching pool body 1 is parallel to or higher than the ground. A lifting device 2 is also fixed on the top of the quenching pool body 1. The lifting device 2 is used to lower the aluminum alloy plate into the quenching pool body 1 for quenching.

[0027] The blowing device 3 includes a blowing pipe 31, which is arranged vertically and horizontally at the bottom of the quenching tank body 1 and is connected to each other. The blowing pipe 31 is densely provided with blowing ports 32 for gas ejection. The design of the blowing port 32 can be further optimized as a nozzle with adjustable angle or direction to enhance the distribution uniformity and stirring effect of the bubbles in the quenching liquid. Some of the blowing ports 32 can be designed to be tilted upward or downward to form a multi-dimensional bubble movement path and improve the cooling efficiency. The blowing pipe 31 is also connected to a main pipeline 33, one end of which extends to the outside of the quenching tank body 1 and is connected to the gas generating device.

[0028] By providing blow pipes 31 arranged vertically and horizontally, with blow ports 32 densely distributed throughout, this design allows the blown gas to form numerous bubbles in the quenching liquid. The bursting of these bubbles effectively stirs the quenching liquid, significantly improving the cooling efficiency of the aluminum alloy sheet. The vertical and horizontal arrangement of the blow pipes 31 further enhances the stirring effect, ensuring rapid and uniform cooling of the aluminum alloy sheet.

[0029] A cooling device 4 is also provided on the outside of the quenching pool body 1. The cooling device 4 is used to cool the quenching liquid in the quenching pool body 1. The cooling device 4 includes a first connecting pipe 45 and a second connecting pipe 46. One end of the first connecting pipe 45 is connected to a position near the bottom of one side of the quenching pool body 1, and one end of the second connecting pipe 46 is connected to a position near the top of the other side of the quenching pool body 1. The other ends of the first connecting pipe 45 and the second connecting pipe 46 are connected to a heat dissipation pipe 42. The heat dissipation pipe 42 is the core component of the cooling device 4 and can be made of high-efficiency heat dissipation materials, such as copper pipes or aluminum pipes, and has built-in heat dissipation fins to increase the heat exchange area.

[0030] Cooling device 4 primarily uses heat exchange to cool the quenching liquid in quench tank body 1, which has been heated during the quenching process. Specifically, the high-temperature quenching liquid is drawn from the bottom of quench tank body 1 through second connecting pipe 46. After heat exchange through heat dissipation pipe 42, the cooled quenching liquid is returned to the top of quench tank body 1 through first connecting pipe 45, achieving cyclic cooling of the quenching liquid.

[0031] The heat dissipation pipe 42 is S-shaped and evenly arranged in multiple layers. Several heat-conducting fins 41 are also located on the outside of the heat dissipation pipe 42, with spaces between each fin 41 for air flow. The cooling device 4 also includes a pump 43 and a cooling fan 44. The pump 43 is mounted on a second connecting pipe 46 and is responsible for extracting the quenching liquid, which has been heated during the quenching process, from the quenching tank body 1 and delivering it to the heat dissipation pipe 42 through the second connecting pipe 46. Due to the action of the pump 43, the quenching liquid can be continuously and stably circulated between the quenching tank body 1 and the heat dissipation pipe 42. The pump 43 is used to transport the quenching liquid from the quenching tank body 1 to the heat dissipation pipe 42. The heat of the quenching liquid is transferred from the heat dissipation pipe 42 to the heat dissipation fins 41. After entering the heat dissipation pipe 42, the heat is transferred to the external heat dissipation fins 41 through the pipe wall of the heat dissipation pipe 42. The heat pipe 42 is S-shaped and evenly arranged in multiple layers. This design increases the flow path and residence time of the quenching liquid within the heat pipe 42, thereby improving heat exchange efficiency. A cooling fan 44 is also fixed to the heat sink 41. The cooling fan 44 circulates air, removing heat from the heat sink 41. When the cooling fan 44 is activated, it also drives the surrounding air flow. As air flows through the heat sink 41, it absorbs heat from the heat sink 41 and removes it, creating an effective convection cooling effect. The presence of air space between each heat sink 41 further promotes air convection and heat dissipation.

[0032] As the quenching liquid absorbs the heat of the aluminum alloy plate and its temperature rises, the cold water is in the lower layer of the hot water, and the pump body 43 is started. The pump body 43 draws the hot water in the upper layer into the heat dissipation pipe 42. Since the heat dissipation pipe 42 is arranged in an "S" shape, the heat is transferred to the heat sink 41. Due to the special shapes of the heat dissipation pipe 42 and the heat dissipation fin 41, the heat conduction effect is better. Then, by starting the heat dissipation fan 44, the heat dissipation fan 44 causes air to flow, thereby taking out the heat on the heat sink 41 and the heat dissipation pipe 42. Subsequently, the cooled quenching liquid enters the quenching pool body 1 from the bottom of one end of the quenching pool body 1, thereby realizing the dynamic recycling of the quenching liquid.

[0033] The lifting device 2 includes a support member 21 and a support platform 22. The support member 21 serves as the basic structure of the entire lifting device 2. The support member 21 is firmly fixed above the quenching pool body 1, providing a solid support platform for the drive device 23 and the support platform 22. Drive devices 23 are fixed on both sides of the top of the support member 21. The drive device 23 is used to move the support platform 22 up and down, placing the aluminum alloy plate into the quenching pool body 1 or lifting the aluminum alloy plate in the quenching pool body 1 to its top. A conveying roller 221 is also rotatably provided on the support platform 22, and a mounting frame 5 is placed on the conveying roller 221. The aluminum alloy plate is placed on the mounting frame 5 and fixed by a fixing device. The drive device 23 includes a rotating shaft 231 and a rotating driving member 235. The rotating shaft 231 The movable device is mounted on top of the support member 21. At least one set of sprockets 232 are symmetrically mounted on the rotating shaft 231. A chain 233 is engaged with the sprockets 232. One end of the chain 233 is connected to a connecting rod 234, which is interconnected with the support platform 22. The other end of the chain 233 is also connected to a counterweight device (not shown). A rotating drive 235 is used to drive the rotating shaft 231. The rotating drive 235 can be a motor, a reducer, or the like, and is used to drive the rotating shaft 231. The conveyor roller 221 in the lifting device 2 is equipped with a mounting bracket 5 for placing and securing the aluminum alloy sheet. When the aluminum alloy sheet needs to be fed into the quenching tank body 1, the rotating drive 235 is activated, driving the rotating shaft 231 to rotate. The sprockets 232 on the rotating shaft 231 drive the chain 233, which, via the connecting rod 234, moves the support platform 22, the aluminum alloy sheet thereon, and the mounting bracket 5 downward into the quenching tank. During the quenching process, the lifting device 2 remains stationary. Once quenching is complete, the rotary drive member 235 rotates in the opposite direction, driving the support platform 22 and the aluminum alloy sheet on it to its initial position via the chain 233. Throughout this process, the conveyor rollers 221 provide stable support and conveyance for the aluminum alloy sheet, ensuring convenient and safe operation.

[0034] Working principle: The quenching pool body 1 is buried underground, and the conveying device is docked with the support platform 22 and the conveying roller 221 on the lifting device 2. The aluminum alloy plate is fixed on the mounting frame 5 through a fixing device, and then the mounting frame 5 and the aluminum alloy plate are placed in the conveying device through a hoist. Then, the conveying device conveys the mounting frame 5 and the aluminum alloy plate to the conveying roller 221. By starting the rotating drive member 235, the rotating drive member 235 rotates the rotating shaft 231, and the rotating shaft 231 rotates the sprocket 232. The sprocket 232 causes the support platform 22 to enter the quenching pool body 1 through the chain 233, and then the aluminum alloy plate enters the quenching pool body 1 for cooling, and the gas is introduced into the blowing pipe 31 through the gas generating device, and then the gas blown out of the blowing port 32 forms bubbles. Afterwards, the bubbles burst and the quenching liquid is continuously stirred. The vertically and horizontally arranged air blowing pipes 31 are used to increase the stirring efficiency, thereby quickly cooling the aluminum alloy plate. Since the quenching liquid absorbs the heat of the aluminum alloy plate and the temperature rises, the cold water is in the lower layer of the hot water. The pump body 43 is started, and the pump body 43 draws the upper layer of hot water into the heat dissipation pipe 42. Since the heat dissipation pipe 42 is arranged in an "S" shape, the heat is transferred to the heat sink 41. Due to the special shapes of the heat dissipation pipe 42 and the heat dissipation fin 41, the heat conduction effect is better. Then, by starting the heat dissipation fan 44, the heat dissipation fan 44 makes the air flow, thereby taking out the heat on the heat sink 41 and the heat dissipation pipe 42. Subsequently, the cooled quenching liquid enters the quenching pool body 1 from the bottom of one end of the quenching pool body 1, thereby realizing the dynamic recycling of the quenching liquid.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
