Description

Technical Field

[0001] This utility model relates to the field of aluminum profile production technology, and in particular to a multi-stage hot air utilization structure for an aluminum profile aging furnace. Background Technology

[0002] Aluminum profiles are strip materials with specific cross-sectional shapes and dimensions made of aluminum alloy. As an important non-ferrous metal structural material, aluminum profiles play a vital role in various fields. With continuous technological advancements and market expansion, the application prospects of aluminum profiles will become even broader. The production process of aluminum profiles requires the use of an aging furnace, which provides a simple heat treatment environment for the aluminum profiles.

[0003] However, traditional aging furnaces rely on manual control of feeding, discharging, and furnace door opening, resulting in hot air escape, low integration, low waste heat utilization, high energy costs, direct hot air emission, significant heat energy waste, and low hot air circulation efficiency. With technological advancements and increased environmental awareness, the aluminum profile industry is moving towards high performance, high environmental friendliness, and high added value. In the future, aluminum profile manufacturers will place greater emphasis on the research and development of environmentally friendly technologies to meet the diverse needs of different sectors.

[0004] For example, the hot air discharged from the aging furnace is directly released into the atmosphere, which not only wastes a lot of thermal energy and increases the energy consumption and costs of enterprises, but may also cause thermal pollution to the environment. Therefore, developing a method that can realize multi-stage utilization of hot air and improve energy efficiency is of great significance to the aluminum profile processing industry. Utility Model Content

[0005] This utility model discloses a multi-stage hot air utilization structure for aluminum profile aging furnaces, aiming to solve the technical problems of direct hot air discharge, low waste heat utilization rate, high energy consumption cost, and serious heat energy waste in traditional aging furnaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-stage hot air utilization structure for an aluminum profile aging furnace includes a heating furnace, a holding furnace, a converter furnace, and a conveyor plate. It further includes: a hot air circulation mechanism: the hot air circulation mechanism includes a first circulation pipe disposed on the top of the heating furnace, a high-power burner disposed on the first circulation pipe, a first circulation fan disposed on the first circulation pipe, and a first hot air plate disposed at one end of the first circulation pipe; a second circulation pipe disposed on the top of the holding furnace, a low-power burner disposed on the second circulation pipe, a second circulation fan disposed on the second circulation pipe, and a second hot air plate disposed at one end of the second circulation pipe; and a waste heat recovery mechanism: the waste heat recovery mechanism is disposed on the outer wall of the heating furnace.

[0008] In this scheme, by setting up a hot air circulation mechanism, energy utilization efficiency can be improved through hot air circulation and heat recovery. In specific use, when the heating furnace starts working, the high-power burner quickly raises the furnace temperature through the first hot air plate, and then the first circulating fan continuously circulates the hot air in the furnace to ensure a constant furnace temperature. At the same time, when the heat preservation furnace starts working, the low-power burner quickly raises the furnace temperature to a constant temperature through the second hot air plate, and then the second circulating fan continuously circulates the hot air in the furnace to ensure a constant furnace temperature.

[0009] In a preferred embodiment, a second lifting door is provided at the connection between the furnace to be converted and the heating furnace, a third lifting door is provided at the connection between the holding furnace and the heating furnace, a first lifting door is provided on the left side of the furnace to be converted, and a fourth lifting door is provided on the right side of the holding furnace. The drive mechanisms of the first, second, third, and fourth lifting doors are all connected to an intelligent controller.

[0010] By replacing manual control of the lifting and lowering of the four furnace doors with an intelligent controller, a large amount of spillage inside the furnace is effectively avoided. The operation is simple and convenient, which effectively improves production efficiency. At the same time, it not only reduces the processing space of each process, but also improves temperature uniformity, reduces heat dissipation of the furnace body, reduces energy consumption, and has a high thermal energy utilization rate, but also avoids the traditional high-intensity material loading and unloading work.

[0012] When the heating furnace or heat preservation furnace finishes its work, the corresponding valve is opened, and the remaining hot air in the furnace can be recovered and reused through the recovery fan. The hot air can then be further heated by the hot air recovery pipe to heat other media that need heating, such as domestic water or water in the workshop heating system, thus realizing the secondary utilization of the hot air heat.

[0013] As described above, a multi-stage hot air utilization structure for an aluminum profile aging furnace includes a heating furnace, a holding furnace, a converter furnace, and a transport plate. It further includes: a hot air circulation mechanism: the hot air circulation mechanism includes a first circulation pipe disposed on the top of the heating furnace, a high-power burner disposed on the first circulation pipe, a first circulation fan disposed on the first circulation pipe, and a first hot air plate disposed at one end of the first circulation pipe; a second circulation pipe disposed on the top of the holding furnace, a low-power burner disposed on the second circulation pipe, a second circulation fan disposed on the second circulation pipe, and a second hot air plate disposed at one end of the second circulation pipe; and a waste heat recovery mechanism: the waste heat recovery mechanism is disposed on the outer wall of the heating furnace. The multi-stage hot air utilization structure for an aluminum profile aging furnace provided by this utility model has the technical effects of improving waste heat utilization rate, reducing energy consumption costs, improving hot air circulation efficiency, avoiding traditional high-intensity material handling work, and being simple and convenient to operate, effectively improving production efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The hot air multi-stage utilization structure for aluminum profile aging furnace disclosed in this utility model is mainly applied to scenarios where traditional aging furnaces directly discharge hot air, resulting in low waste heat utilization, high energy consumption costs, and serious waste of thermal energy.

[0022] Reference Figure 1 and Figure 2 A multi-stage hot air utilization structure for an aluminum profile aging furnace includes a heating furnace 1, a holding furnace 2, a converter furnace 3, and a transport plate 19. It also includes: a hot air circulation mechanism: the hot air circulation mechanism includes a first circulation pipe 7 installed on the top of the heating furnace 1, a high-power burner 8 installed on the first circulation pipe 7, a first circulation fan 10 installed on the first circulation pipe 7, and a first hot air plate 15 installed at one end of the first circulation pipe 7; a second circulation pipe 11 installed on the top of the holding furnace 2, a low-power burner 12 installed on the second circulation pipe 11, a second circulation fan 14 installed on the second circulation pipe 11, and a second hot air plate 17 installed at one end of the second circulation pipe 11; and a waste heat recovery mechanism: the waste heat recovery mechanism is installed on the outer wall of the heating furnace 1.

[0023] In actual use, when the heating furnace 1 starts working, the high-power burner 8 quickly raises the temperature inside the furnace through the first hot air plate 15, and then the hot air inside the furnace is continuously circulated through the first circulating fan 10 to ensure that the temperature inside the furnace is constant. At the same time, when the heat preservation furnace 2 starts working, the low-power burner 12 quickly raises the temperature inside the furnace to a constant temperature through the second hot air plate 17, and then the hot air inside the furnace is continuously circulated through the second circulating fan 14 to ensure that the temperature inside the furnace is constant.

[0024] The first circulation pipe 7 is equipped with a first corrugated pipe 9, and the second circulation pipe 11 is equipped with a second corrugated pipe 13.

[0025] Specifically, the corrugated pipe can be used as a compensation element for both natural and forced compensation of the pipeline. In natural compensation, the corrugated pipe can automatically adapt to temperature changes and terrain elevation differences in the pipeline, reducing pipeline stress and deformation. In forced compensation, the corrugated pipe can control the pressure of the external medium to achieve pipeline displacement, which also helps to reduce pipeline stress and deformation. This can improve the stability and safety of the pipeline system, enhance seismic performance, ensure the safety and purity of the transmitted medium, extend service life, and reduce installation and maintenance costs.

[0026] The first hot air plate 15 is provided with several first hot air equalization branch pipes 16, and the second hot air plate 17 is provided with several second hot air equalization branch pipes 18.

[0027] Specifically, the structural design of the uniform flow branch pipe can evenly distribute hot air, ensuring a uniform temperature in all areas of the hot air plate; improve thermal efficiency by reducing heat waste through effective heat exchange; enhance system stability and avoid malfunctions caused by local overheating or uneven temperature; and optimize the structural layout to flexibly adapt to hot air plates of different sizes and shapes, thereby improving the system's versatility and practicality.

[0028] Reference Figure 1 and Figure 4 In a preferred embodiment, the waste heat recovery mechanism includes a hot air recovery pipe 4 installed on the outer wall of the heating furnace 1 and the heat preservation furnace 2, a recovery fan 6 installed on the hot air recovery pipe 4, and a valve 5 installed at the connection between the hot air recovery pipe 4 and the heating furnace 1 and the heat preservation furnace 2.

[0029] Specifically, when the heating furnace 1 or the heat preservation furnace 2 finishes its work, the corresponding valve 5 is opened, and the remaining hot air in the furnace can be recovered and reused through the recovery fan 6. Through the transmission of the hot air recovery pipe 4, other media that need to be heated, such as domestic water and water in the workshop heating system, can be further heated to realize the secondary utilization of the heat of the hot air.

[0030] Reference Figure 1 and Figure 3 In a preferred embodiment, a second lifting door 22 is provided at the connection between the converter 3 and the heating furnace 1, a third lifting door 23 is provided at the connection between the heat preservation furnace 2 and the heating furnace 1, a first lifting door 21 is provided on the left side of the converter 3, and a fourth lifting door 24 is provided on the right side of the heat preservation furnace 2. The drive mechanisms of the first lifting door 21, the second lifting door 22, the third lifting door 23 and the fourth lifting door 24 are all connected to the intelligent controller.

[0031] Specifically, by using an intelligent controller to replace manual control of the lifting and lowering of the four furnace doors, a large amount of spillage inside the furnace is effectively avoided. The operation is simple and convenient, effectively improving production efficiency. At the same time, it not only reduces the processing space of each process, but also improves temperature uniformity, reduces heat dissipation of the furnace body, lowers energy consumption, and has high thermal energy utilization, but also avoids the traditional high-intensity material loading and unloading work.

[0032] The bottom of the first lifting door 21, the second lifting door 22, the third lifting door 23 and the fourth lifting door 24 are all equipped with sealing gaskets.

[0033] Specifically, the sealing gasket has excellent cushioning, shock absorption and protection performance. It can fit tightly against the surface of the equipment, reduce heat loss, save energy and protect the environment, improve the utilization rate of heat, and effectively isolate external impacts, vibrations and friction and other adverse factors, thereby ensuring stable operation of the equipment and extending its service life.

[0034] Reference Figure 1 and Figure 3 In a preferred embodiment, a rotating wheel 20 is provided at the bottom of the transport plate 19, and a drive device is provided inside the rotating wheel 20. The drive device is connected to the intelligent controller.

[0035] Specifically, the intelligent controller controls the start and stop of the transport plate 19 to achieve intelligent loading and unloading, effectively reducing the traditional high-intensity manual material handling work.

[0036] Working principle: During use, in the heating stage: when the heating furnace 1 is started, the high-power burner 8 starts working, and blows hot air into the furnace quickly through the first hot air plate 15, causing the furnace temperature to rise rapidly. Subsequently, the first circulating fan 10 starts, continuously circulating the hot air in the furnace to ensure that the furnace temperature is maintained at a constant level. The first hot air equalization branch pipe 16 on the first hot air plate 15 helps to distribute the hot air evenly and ensure that the temperature in each area of ​​the furnace is balanced. In the heat preservation stage: when the aluminum profile needs to be further processed in the heat preservation furnace 2, the low-power burner 12 quickly raises the furnace temperature to the required constant temperature through the second hot air plate 17. After that, the second circulating fan 14 starts, circulating the hot air in the furnace to maintain a stable temperature. The second hot air equalization branch pipe 18 on the second hot air plate 17 also plays the role of evenly distributing hot air. After the heating furnace 1 or the heat preservation furnace 2 has finished working, the remaining hot air in the furnace is extracted through the hot air recovery pipe 4 by opening the corresponding valve 5 and using the recovery fan 6. This hot air can be further used to heat other media, such as domestic water or water in the workshop heating system, to realize the secondary utilization of hot air heat and improve energy utilization efficiency.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
