Description

Technical Field

[0001] This utility model relates to the field of aging furnace technology, specifically to a bidirectional hot air aging furnace for aluminum profiles. Background Technology

[0002] An aging furnace is a specialized heat treatment device used to age metallic materials (such as aluminum alloys and magnesium alloys). Aging treatment is a metal heat treatment process that aims to eliminate internal stresses generated during earlier processing (such as cold working and casting) by holding the material at a specific temperature for a period of time. This stabilizes the material's microstructure and dimensions, improves its mechanical properties (such as strength, hardness, and toughness), and enhances its corrosion resistance. In the production and processing of aluminum profiles, aging treatment is a crucial step, significantly improving the mechanical properties and stability of the aluminum profiles.

[0003] Traditional aging furnaces often have simple hot air delivery systems, with hot air only entering the furnace from one direction or a few points, resulting in extremely uneven hot air distribution. This uneven distribution leads to uneven heating of the aluminum profiles during the aging process, with some areas potentially overheating while others are underheated, thus affecting the overall aging effect and product quality. Simultaneously, dust and impurities in the air can easily enter the furnace with the hot air, adhering to the aluminum profile surface and forming a contamination layer. This contamination layer not only affects the surface quality of the aluminum profiles but may also interfere with the aging process, leading to a decline in product quality. Furthermore, the uneven heat transfer in traditional aging furnaces results in large temperature gradients and unstable temperatures within the furnace. This unstable temperature environment reduces production efficiency during the aging process. Therefore, a bidirectional hot air aging furnace for aluminum profiles needs to be designed.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] Example 1:

[0020] The present invention addresses the problems of uneven hot air distribution in traditional aging furnaces, leading to uneven heating of aluminum profiles in different locations within the furnace and affecting the aging process and product quality. It also addresses the issues of uneven heat transfer in traditional heating elements, resulting in unstable furnace temperatures and impacting the aging quality of aluminum profiles. A preferred embodiment of this invention is a bidirectional hot air aging furnace for aluminum profiles. Figure 1-4The image shows a bidirectional hot air aging furnace for aluminum profiles, comprising an aging furnace body 1. Two hinged doors 2 are mounted on the front of the furnace body 1. A temperature detection display 3 and a switch handle 4 are fixedly mounted on the front of the doors 2. A control box 5 is fixedly mounted on the outer wall of the furnace body 1, and a protective top cover 6 is fixedly mounted on the top of the furnace body 1. A bidirectional hot air assembly 7 is located inside and above the furnace body 1. The bidirectional hot air assembly 7 includes: a bidirectional air blowing section 71, located inside and above the furnace body 1; and a hot air circulation section 72, located inside and outside the furnace body 1, and also inside and outside the bidirectional air blowing section 71.

[0021] The bidirectional air blowing part 71 includes: air holes 711, which are evenly spaced on the outer wall of the protective top cover 6 and are located on all four outer walls of the protective top cover 6; a mouth-shaped locking hole 712, which is located on the top of the protective top cover 6; a fixing seat 713 is installed inside the mouth-shaped locking hole 712 by a locking mechanism, and a replacement handle 714 is fixedly installed on the top of the fixing seat 713.

[0022] A filter plate 715 is fixedly installed at the bottom of the fixed bracket 713, and the filter plate 715 is compatible with the air hole 711. The interior of the air hole 711 is located in the mounting base 716, and the mounting base 716 is fixedly installed on the top of the aging furnace body 1. There are two sets of mounting bases 716, and a fan 717 is fixedly installed on the top of the mounting base 716.

[0023] The connection port of the blower 717 is connected to a conveying pipe 718, which movably passes through the top of the aging furnace body 1 and extends into the interior of the aging furnace body 1. The other end of the conveying pipe 718 is connected to a two-way plate 719, which is fixedly installed on the inner wall of the aging furnace body 1. There are two sets of two-way plates 719, which are located on the inner walls of the two sides of the aging furnace body 1 and are arranged symmetrically.

[0024] The bidirectional plate 719 has an internal mounting groove, and a serpentine drain pipe 7110 is installed inside the mounting groove. The outer wall of the serpentine drain pipe 7110 has a blow hole 7111. A guide arc plate 7112 is installed in front of the blow hole 7111. The guide arc plate 7112 is fixedly installed on the inner wall of the mounting groove at equal intervals. The inner side wall of the bidirectional plate 719 has elongated blow holes 7113 at equal intervals.

[0025] Furthermore, this embodiment, by providing a notch-shaped card hole 712, a fixed card seat 713, and a fine air filter plate 715, can effectively filter dust, impurities, etc. in the air entering the aging furnace body 1, preventing these impurities from adhering to the surface of the aluminum profile or affecting the normal operation of the equipment inside the furnace, ensuring the surface quality of the aluminum profile and the cleanliness of the furnace environment. Together with the air hole 711, it ensures that air can enter the interior of the protective top cover 6 evenly from multiple directions. At the same time, the fan 717 delivers air to the interior of the bidirectional plate 719 through the conveying pipe 718, realizing bidirectional air blowing. Together with the serpentine exhaust pipe 7110, the air blowing hole 7111, and the guide arc plate 7112 installed at equal intervals in front, the hot air is reasonably guided and distributed, so that the hot air can be evenly blown out from the air blowing holes 7113 evenly opened at equal intervals on the inner side wall of the bidirectional plate 719, and evenly act on the aluminum profile.

[0026] Example 2:

[0027] Please see Figures 1-4 Furthermore, based on Embodiment 1, the hot air circulation part 72 includes: a fixing frame 721, which is fixedly installed on the inner wall of the aging furnace body 1; a mounting box 724, which is fixedly installed on the bottom of the inner wall of the aging furnace body 1 and located at the bottom of the fixing frame 721; a support partition 722 is fixedly installed at equal intervals on the inner wall of the fixing frame 721, and an aluminum profile is placed above the support partition 722; and air vents 723 are evenly opened at equal intervals on the outer wall of the fixing frame 721.

[0028] Heating resistance wires 725 are fixedly installed inside the mounting box 724 at equal intervals. A heat transfer sealing plate 726 is fixedly installed on the top of the mounting box 724. Heat transfer holes 727 are opened at equal intervals on the top of the heat transfer sealing plate 726.

[0029] A return air conveying pipe 728 is provided behind the fixed frame 721, and the return air conveying pipe 728 movably passes through the rear surface of the aging furnace body 1 and extends into the interior of the protective top cover 6. A sealing ring 729 is fitted on the outer wall of the return air conveying pipe 728.

[0030] Furthermore, this embodiment, by providing a fixing frame 721 and a supporting partition 722, allows the aluminum profiles to be placed neatly and orderly inside the aging furnace body 1, facilitating the uniform blowing of hot air and aging treatment. The air vents 723 ensure that the hot air can circulate freely inside the aging furnace body 1, allowing the hot air to fully contact the aluminum profiles. Simultaneously, the mounting box 724 and the heating resistance wire 725 can generate heat quickly and evenly, providing a stable heat source for the aging furnace body 1. This allows the heat to be evenly transferred to the heat transfer sealing plate 726. The heat transfer holes 727 can also evenly transfer the heat generated by the heating resistance wire 725 into the aging furnace body 1, making the furnace temperature more uniform and beneficial for the uniform aging treatment of the aluminum profiles.

[0031] In use, firstly, the fan works: the fan 717 is started by the control box 5, and the fan 717 starts to run. Air is transported through the delivery pipe 718 connected by the connection port. Then, in the heating process, the heating resistance wire 725 fixedly installed inside the mounting box 724 is energized and heats up. The heat generated is transferred upward through the heat transfer holes 727 evenly spaced at the top of the heat transfer sealing plate 726.

[0032] Furthermore, hot air is formed within the bidirectional plate. The conveying pipe 718 delivers air to the mounting groove inside the bidirectional plate 719, where it combines with the heat transferred by the heating resistance wire 725 to form hot air. The outer wall of the serpentine exhaust pipe 7110 within the mounting groove has air blowing holes 7111, from which hot air is blown out. Next, the guide arc plate 7112 positioned in front of the air blowing holes 7111 guides the hot air, ensuring it is evenly blown into the aging furnace body 1 through the equidistant and uniformly spaced elongated air blowing holes 7113 on the inner wall of the bidirectional plate 719. Since the bidirectional plates 719 are located on both sides of the inner wall of the aging furnace body 1 and are symmetrically arranged, bidirectional air blowing is achieved.

[0033] Furthermore, the hot air comes into contact with the aluminum profile: the hot air flows inside the aging furnace body 1, and comes into contact with the aluminum profile placed above the support partition 722 through the air vents 723 evenly spaced on the outer wall of the fixing frame 721, thus aging the aluminum profile. After contacting the aluminum profile, the hot air temperature decreases, forming return air inside the aging furnace body 1. This return air is then carried out through the rear surface of the aging furnace body 1 via the return air conveying pipe 728 located behind the fixing frame 721, and extends into the interior of the protective top cover 6, realizing the recovery of hot air. The sealing ring 729 fitted on the outer wall of the return air conveying pipe 728 ensures the airtightness during the return air conveying process.

[0034] Furthermore, the recovered return air mixes with the fresh air delivered by the fan 717 inside the protective top cover 6, and then re-enters the bidirectional plate 719 for heating and delivery, forming a hot air circulation.

[0035] Air filtration: Air inlets 711, evenly spaced on the outer wall of the protective top cover 6, allow air to enter. A fine filter plate 715, fixedly mounted at the bottom of the inlet-shaped locking hole 712 via a snap-fit ​​mounting bracket 713, filters the incoming air. The filter plate 715 fits into the air inlets 711. A replacement handle 714, fixedly mounted on the top of the mounting bracket 713, facilitates the replacement and cleaning of the filter plate 715. Next, a temperature detection display 3, fixedly mounted on the front of the opening / closing door 2, monitors the temperature inside the aging furnace body 1 in real time and displays the temperature data. This allows operators to adjust the heating power of the heating resistance wire 725 and the airflow speed of the fan 717 via the control box 5, ensuring the internal temperature of the aging furnace body 1 remains stable within a suitable range and guaranteeing the aging treatment effect of the aluminum profiles.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
