Description

Technical Field

[0001] This utility model relates to the field of aluminum rod processing technology, specifically a cooling device for aluminum rod processing. Background Technology

[0002] The cooling process after aluminum rod processing is a key factor affecting its performance and quality. The main purpose of cooling aluminum rods is to control their microstructure, eliminate internal stress, improve performance stability, and ensure processing quality.

[0003] The most common cooling equipment is the quenching equipment for aluminum rod processing. The core of the quenching process is "rapid cooling", which means immersing the metal heated to the austenitizing temperature into a cooling medium (such as water, oil, polymer solution) to cause it to undergo martensitic or bainitic phase transformation.

[0004] In existing technologies, the quenching of aluminum bars, especially water cooling, generates a large amount of steam. This steam rises rapidly, carrying a large amount of water. If it is not recovered, it will result in unnecessary water waste. Therefore, an improved cooling device for aluminum bar processing is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for aluminum rod processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for aluminum rod processing, comprising a quenching water tank, wherein a recovery mechanism for condensing and recovering steam is provided at the upper end of the quenching water tank, the recovery mechanism comprising a support, a top plate, a first heat exchange fin plate, a connecting plate, and a second heat exchange fin plate, the support being fixedly provided on both sides of the surface of the quenching water tank, the top plate being fixedly provided at the upper end of the support, a plurality of first heat exchange fin plates being uniformly fixedly provided at the lower end of the top plate, the connecting plate being fixedly provided at the upper end of the first heat exchange fin plates, and a plurality of second heat exchange fin plates being uniformly fixedly provided at the upper end of the connecting plate, wherein the first heat exchange fin plates, the connecting plate, and the second heat exchange fin plates are all hollow inside and interconnected.

[0007] Preferably, the first heat exchange fin plate is filled with a thermosensitive liquid. This device uses phase change heat dissipation to condense steam. Based on the quenching steam temperature (90-100℃), the boiling point of the thermosensitive liquid should be 10-20℃ lower than the steam temperature. For example, R134a with a boiling point of 78℃ or n-hexane with a boiling point of 69℃ can be used (this is just an example; the appropriate thermosensitive liquid can be selected according to environmental protection and cost requirements). Stable phase change heat dissipation can be achieved in a 95℃ steam environment, thereby rapidly condensing the steam into water that accumulates on the surface of the first heat exchange fin plate. Then, under the action of gravity, it can fall back into the quenching water tank. Meanwhile, the thermosensitive liquid inside the first heat exchange fin plate evaporates, carrying away heat into the larger second heat exchange fin plate for natural heat exchange with the external environment. Subsequently, it condenses back into liquid and flows back into the first heat exchange fin plate to repeat the steam condensation process. In this way, this device recovers steam water by removing steam heat through phase change heat dissipation, without the need for complex heat exchange pipes or electricity; the effect is good.

[0008] Preferably, a guide fan is fixedly installed on the surface of the second heat exchange fin plate. The guide fan of this device is not always on. It is only started when the natural heat exchange cannot meet the condensation of the heat-sensitive liquid under high-intensity heat exchange conditions, so as to save electricity to the greatest extent.

[0009] Preferably, a slide rail is fixedly installed at the lower center of the top plate, and a lifting device is movably installed on the surface of the slide rail. A power component is installed at the upper end of the lifting device so that the lifting device can move left and right along the slide rail. This device can lift the aluminum rod that needs to be quenched and cooled into the quenching tank for cooling and quenching operations by moving the lifting device left and right along the slide rail. The lifting device of this device is a mature existing technology, so it will not be described in detail in this application.

[0010] Preferably, a connecting pipe is fixedly installed on one side of the surface of the quenching water tank, through which water can be added to or drained from the quenching water tank.

[0011] Preferably, baffles are fixedly installed between the supports to reduce the outward dispersion of energy that normally bypasses the top plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model can quickly condense the large amount of steam generated during the quenching and cooling of aluminum rods and allow the steam to flow back into the water tank, thus playing the role of water recycling and preventing water waste.

[0014] 2. When this utility model is used, the heat of steam is transferred through the phase change heat exchanger to recover steam water, which eliminates the need for complex heat exchange pipes and electricity; the effect is good. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6This utility model provides a technical solution: a cooling device for aluminum rod processing, including a quenching water tank 1. The upper end of the quenching water tank 1 is provided with a recovery mechanism for condensing and recovering steam. The recovery mechanism includes a support 2, a top plate 3, a first heat exchange fin plate 4, a connecting plate 5, and a second heat exchange fin plate 6. The support 2 is fixedly installed on both sides of the surface of the quenching water tank 1. The top plate 3 is fixedly installed on the upper end of the support 2. A plurality of first heat exchange fin plates 4 are evenly fixedly installed on the lower end of the top plate 3. The connecting plate 5 is fixedly installed on the upper end of the first heat exchange fin plate 4. A plurality of second heat exchange fin plates 6 are evenly fixedly installed on the upper end of the connecting plate 5. The first heat exchange fin plate 4, the connecting plate 5, and the second heat exchange fin plate 6 are all hollow inside and interconnected.

[0024] The first heat exchange fin plate 4 is filled with a thermosensitive liquid. This device uses phase change heat dissipation to condense steam. Based on the quenching steam temperature (90-100℃), the boiling point of the thermosensitive liquid must be 10-20℃ lower than the steam temperature. For example, R134a with a boiling point of 78℃ or n-hexane with a boiling point of 69℃ can be used (this is just an example; a suitable thermosensitive liquid can be selected based on environmental and cost requirements). Stable phase change heat dissipation can be achieved in a 95℃ steam environment, allowing the steam to quickly condense into water and accumulate on the surface of the first heat exchange fin plate 4. Then, under gravity, the water falls back into the quenching water tank 1. Meanwhile, the thermosensitive liquid inside the first heat exchange fin plate 4 evaporates, carrying away heat into the larger second heat exchange fin plate 6 for natural heat exchange with the external environment. It then condenses back into liquid and flows back into the first heat exchange fin plate 4 to repeat the steam condensation process. In this way, the device recovers steam water by removing steam heat through phase change heat dissipation, eliminating the need for complex heat exchange pipes and electricity; the effect is excellent.

[0025] A guide fan 7 is fixedly installed on the surface of the second heat exchange fin plate 6. The guide fan 7 of this device is not always on. It is only started when the natural heat exchange cannot meet the condensation of the heat-sensitive liquid under high-intensity heat exchange conditions, so as to save electricity to the greatest extent.

[0026] A slide rail 8 is fixedly installed at the lower center of the top plate 3. A lifting device 9 is movably installed on the surface of the slide rail 8. A power component 10 is installed at the upper end of the lifting device 9 so that the lifting device 9 can move left and right along the slide rail 8. This device can lift the aluminum bar that needs to be quenched and cooled into the quenching tank for cooling and quenching by moving the lifting device 9 left and right along the slide rail 8. The lifting device 9 of this device is a mature existing technology, so it will not be described in detail in this application document.

[0027] A connecting pipe 11 is fixedly installed on one side of the surface of the quenching water tank 1, through which water can be added to or drained from the quenching water tank 1.

[0028] A baffle 12 is fixedly installed between the brackets 2. The baffle 12 can reduce the situation where the material normally radiates outward around the top plate 3.

[0029] Working principle: When using this device, the aluminum rod to be quenched and cooled is lifted into the quenching tank by moving the lifting equipment 9 left and right along the slide rail 8. During quenching, a large amount of steam is generated. Due to the principle of hot air rising, the steam rises and comes into contact with the first heat exchange fin plate 4. At this time, the heat-sensitive liquid inside the first heat exchange fin plate 4 is heated, absorbs heat and evaporates, thus quickly condensing the steam. The steam condenses into water and accumulates on the surface of the first heat exchange fin plate 4. The surface of the first heat exchange fin plate 4 can be coated with a hydrophobic coating. Under the action of gravity, the water droplets fall back into the quenching water tank 1. In this way, when the aluminum rod is processed and quenched, the large amount of steam generated can be quickly condensed and the steam can be returned to the water tank, thus playing a role in water recycling and preventing water waste.

[0030] Furthermore, this device recovers steam and water by transferring steam heat through a phase change heating element, eliminating the need for complex heat exchange pipes and electricity; it also offers excellent performance.

[0031] Since the steam is not continuous during the quenching and cooling of aluminum bars, and steam is only generated during quenching, and quenching is only one step in the aluminum bar processing, it is not carried out all the time. Therefore, it is difficult to continuously transfer heat, and quenching is also completed quickly. Thus, this device only recovers steam water, but does not recover steam heat.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
