[0065] like Figure 1-3 As shown, an energy-saving and high-efficiency aging furnace for mass production of aluminum alloy profiles is proposed, comprising:

[0066] The furnace body has an entrance door 4 and an exit door 1 at both ends thereof.

[0067] A heating port door 3 is arranged near the entrance door 4 in the furnace body, and a heat recovery preheating zone 7 is arranged between the heating port door 3 and the entrance door 4. A heat dissipation port door 2 is arranged near the exit door 1 in the furnace body, and a heat dissipation zone 5 is arranged between the heat dissipation port door 2 and the exit door 1. An aging heating zone 6 is arranged between the heating port door 3 and the heat dissipation port door 2.

[0068] like Figure 4 As shown, a heat recovery fan 25 and a preheating zone cooling fan 27 are also provided outside the furnace body, and they are fixedly connected by a bracket 26; the heat recovery fan 25 is provided with a recovery pipe 24, and the two ends of the recovery pipe 24 are respectively connected to the recovered heat preheating zone 7 and the heat dissipation zone 5, and the heat recovery direction of the heat recovery fan 25 is from the heat dissipation zone 5 to the recovered heat preheating zone 7; the preheating zone cooling fan 27 is provided with a circulation pipe 28, and the two ends of the circulation pipe 28 are respectively connected to the heat dissipation zone 5 and the recovered heat preheating zone 7, and the wind circulation direction of the preheating zone cooling fan 27 is from the recovered heat preheating zone 7 to the heat dissipation zone 5, which can fully recover the excess heat of the heat dissipation zone 5 and transport it to the recovered heat preheating zone 7 to heat the profile, thereby avoiding the loss of heat energy.

[0069] In order to further recover the heat energy in the heat dissipation zone 5, a loading zone heat recovery port 23 is provided at the port of the recovery pipe 24 located in the heat dissipation zone 5 and is arranged at an angle to the recovery pipe 24 to increase the recovery diameter and improve the recovery efficiency.

[0070] Further, if Figure 1As shown, a first track 17-1 is laid through the entrance door 4, the exit door 1, the heating door 3 and the heat dissipation door 2, and a first flatbed car 29 is arranged on the first track 17-1; and a movable hanging chain group is laid along the side of the first track 17-1, and the hanging chain group can be disconnected and driven by the first flatbed car 29.

[0071] Specifically, the first rails 17-1 are two parallel rails; and, at the entrance door 4, the two outer sides of the first rails 17-1 are respectively provided with a moving-in hanging chain group 8 parallel to the first rails 17-1 on both sides; between the entrance door 4 and the exit door 1, an aging furnace internal hanging chain group 9 parallel to the first rail 17-1 is provided between the two first rails 17-1; at the exit door 1, the two inner sides of the first rail 17-1 are respectively provided with a moving-out hanging chain group 10 parallel to the first rails 17-1 on both sides; and the lengths of the two ends of the aging furnace internal hanging chain group 9 are at least flush with one end of the moving-in hanging chain group 8 close to the aging furnace internal hanging chain group 9 and one end of the moving-out hanging chain group 10 close to the aging furnace internal hanging chain group 9, and the rotation direction of the moving-in hanging chain group 8, the aging furnace internal hanging chain group 9, and the moving-out hanging chain group 10 is the direction from the entrance door 4 to the exit door 1. In this way, the first flatbed car 29 can pass through the aging furnace and complete the aging treatment under the drive of the in-carrying hanging chain group 8, the hanging chain group 9 inside the aging furnace, and the carrying-out hanging chain group 10 in sequence, with a high degree of automation.

[0072] Furthermore, in order to enable multiple flatbed trucks containing profiles 34 to perform aging treatment in sequence, such as Figure 3-6 As shown, the carrying-in hanging chain group 8, the carrying-out hanging chain group 10, and the hanging chain group 9 inside the aging furnace are all provided with a plurality of hanging chain hooks 18 that move with them, and the first flatbed truck 29 is provided with first hooks 30 at positions corresponding to the carrying-in hanging chain group 8, the carrying-out hanging chain group 10, and the hanging chain group 9 inside the aging furnace, respectively. A wheel group 31 is provided at the bottom of the first flatbed truck 29, and the hanging chain hooks 18 match the first hooks 30.

[0073] Specifically, the chain hook 18 includes connecting plates 19 rotatably arranged on both sides of the chain group and symmetrical to each other, a spring 20 is arranged on the front side of the connecting plate 19, one end of the spring 20 is connected to a fixed block 21 fixedly arranged on the chain group, and the other end is connected to the connecting plate 19, and the top ends of the two connecting plates 19 are fixedly connected by a hanging rod 32; arc portions are arranged on the front and rear sides of the first hook 30, and the hanging rod 32 is engaged with the arc portions on one side to realize that when the chain hook 18 moves forward with the chain group, it drives the first flatbed car 29 to move forward synchronously, and the moving speed of the chain group can be controlled by a motor, etc.

[0074] And in order to better take into account the steps of loading, aging treatment, etc., the moving-in hanging chain group 8, the moving-out hanging chain group 10, and the hanging chain group 9 inside the aging furnace are arranged on different lines. In order to achieve the coordination between the hanging chain groups, such as disconnecting the combination of the hanging chain hook 18 of the previous hanging chain group and the first hook 30, so that the hanging chain hook 18 of the next hanging chain group can be combined with the first hook 30, a mobile unhooking group 13 is also arranged on the moving-in hanging chain group 8 and the moving-out hanging chain group 10, and a unhooking device 16 is arranged at one end of the hanging chain group 9 inside the aging furnace close to the moving-out hanging chain group 10, and the mobile unhooking group 13 and the unhooking device 16 are both composed of a cross bar and a connecting rod supporting the cross bar, the height of the cross bar is between the first hook 30 and the hanging chain group, and the length of the cross bar is longer than the distance between the connecting plates 19 on both sides. When the chain hook 18 moves to the unhooking device 16, the blocking of the cross bar causes the connecting plate 19 to separate from the arc portion of the first hook 30, making it convenient for the connecting plate 19 on the next chain group to be combined with the arc portion of the first hook 30, so as to complete the driving of the first flatbed truck 29 during the entire aging treatment process.

[0075] Another example Figure 1 As shown, before loading, a second track 17-2 laid perpendicularly to the first track 17-1 is provided at the end of the moving-in hanging chain group 8 away from the entrance door 4, and a second flatbed car 12 is movably provided on the second track 17-2, so as to facilitate the transportation of the profiles to the vicinity of the entrance door 4 and to facilitate the movement of the profiles to the first flatbed car 29; and after aging treatment, a third track 17-3 laid perpendicularly to the first track 17-1 is provided at the end of the moving-out hanging chain group 10 away from the exit door 1, and a third flatbed car 33 is movably provided on the third track 17-3, and a material frame 11 is provided on the third flatbed car 33, so as to facilitate the transportation of the profiles after aging treatment.

[0076] A fourth track 17-4 is arranged between the second track 17-2 and the third track 17-3 on the outer side of the furnace body, and a fourth flatbed car is movably arranged on the fourth track 17-4. The machine structure and position of the fourth track 17-4 correspond to those of the first track 17-1, and the structure of the fourth flatbed car corresponds to the structure of the first flatbed car 29; and, at a position close to the third track 17-3 on the inner side of the fourth track 17-4, a unloading area chain group 14 corresponding to the structure and position of the unloading chain group 10 is arranged; at a position close to the second track 17-2 on the outer side of the fourth track 17-4, a loading area chain group 22 corresponding to the structure and position of the loading chain group 8 is arranged; between the loading area chain group 22 and the unloading area chain group 14, a mobile chain group 15 corresponding to the structure and position of the chain group 9 inside the aging furnace is arranged. The rotation direction of the unloading area hanging chain group 14, the loading area hanging chain group 22, and the moving hanging chain group 15 is the direction from the third track 17-3 to the second track 17-2. In this way, by laying the first track 17-1, the second track 17-2, the third track 17-3, and the fourth track 17-4, a transportation loop is formed, which is convenient for the profiles to be put on the shelf for aging treatment, and convenient for unloading the treated profiles, which is more intelligent.
