[0002] Aging furnaces are often used to remove stress from metals during metal processing, and can also be used to dry ordinary products. In existing aging furnaces, a cart with metal parts to be processed needs to be pushed into the aging furnace during processing. After the sealed door is closed, the heating element is started, and the air circulation component automatically circulates the airflow in the aging furnace to ensure the flow of hot air so that the metal parts in the furnace are heated more evenly.

[0003] When it is necessary to heat the long strips of aluminum profiles, due to the placement of the aluminum profiles, the hot air blown by the air circulation component can only heat the sides of the aluminum profiles. Therefore, the temperature of the aluminum profiles stacked in the middle rises more slowly than that of the aluminum profiles on the outside, and the heating time needs to be extended to allow the aluminum profiles stacked inside to heat up evenly. Therefore, there is a need for an aging furnace that can reduce the heating time and make the stacked aluminum profiles heated more evenly. Utility Model Content

[0024] The present invention is described in detail below in conjunction with specific embodiments.

[0025] In the present utility model, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0026] like Figures 1 to 9 As shown, the utility model provides an aging furnace for aluminum profiles with uniform heating, including an inner liner 1 and an air circulation component 3, a heating component 2 is arranged on the inner liner 1, the heating component 2 is used to heat the aluminum profile in the inner liner 1, the air circulation component 3 includes a circulation fan blade 32, a fan blade driving component 31 and a furnace body outer cover 30, the inner liner 1 is installed in the furnace body outer cover 30, a plurality of groups of circulation fan blades 32 are installed on the inner liner 1, the fan blade driving component 31 is used to drive the plurality of groups of circulation fan blades 32 to rotate, and a return air duct 34 and a wind chamber 33 are arranged between the inner liner 1 and the furnace body outer cover 30; the circulation fan blade 32 blows the airflow in the wind chamber 33 into the inner liner 1, and the airflow in the inner liner 1 flows to the wind chamber 33 through the return air duct 34.

[0027] In this embodiment, a plurality of groups of rectifying wing plates 35 are provided in the return air duct 34 , and the outer surfaces of the rectifying wing plates 35 are composed of a plurality of circular arcs.

[0028] According to the above design, when the aluminum profile needs to be heated, since the circulation blade 32 is located on one side of the aluminum profile in the longitudinal direction, the airflow blown by the circulation blade 32 will pass through the gaps between the stacked aluminum profiles, so that the aluminum profiles stacked inside can also be evenly heated. The rectifying wing plate 35 in the return air duct 34 can increase the flow rate of the airflow in the return air duct 34, and prevent the air pressure in the air chamber 33 from being too low and affecting the circulation efficiency.

[0029] In this embodiment, a filter 36 is provided in the air chamber 33, and a handle is provided on the filter 36. The filter 36 can filter large particles of impurities generated during combustion, and reduce the damage of impurities in the airflow to the circulating fan blades 32; when the filter 36 needs to be replaced, it is only necessary to pull the handle to pull out the filter 36.

[0030] In this embodiment, the heating assembly 2 includes a gas pipeline 20 installed on the outside of the inner tank 1, an auxiliary pipeline 23, and multiple groups of ignition ports 22 arranged on the gas pipeline 20. The ignition ports 22 are located inside the inner tank 1, and a heat insulation board 21 is arranged outside the gas pipeline 20; the auxiliary pipeline 23 is installed on the inner tank 1, and is used to transport gas for auxiliary combustion into the inner tank 1. The heat insulation board 21 is located in the return air duct 34, and the heat insulation board 21 can prevent the hot air in the return air duct 34 from heating the gas pipeline 20 and the auxiliary pipeline 23, thereby reducing the probability of danger.

[0031] The gas transported by the auxiliary pipeline 23 can be air or oxygen. Transporting gas through the auxiliary pipeline 23 can avoid accidents caused by incomplete combustion of gas in the inner tank 1. Since the relevant gas equipment and technology are relatively mature, they are not described in detail in this embodiment.

[0032] In this embodiment, a guide rail 10 for guiding the cart is provided inside the inner container 1 .

[0033] In this embodiment, a sealed door 4 is hinged on the outer cover 30 of the furnace body, and the sealed door 4 is located on the side of the inner container 1 away from the circulating blades 32. When the sealed door 4 is closed, the airflow blown out by the circulating blades 32 passes through the stacked aluminum profiles and blows on the sealed door 4. Under the guidance of the sealed door 4, the airflow turns to the return air duct 34, and then flows from the return air duct 34 to the wind chamber 33, and continues to complete the circulation of the hot air flow.

[0034] The sealing doors 4 on both sides are provided with lock tongues, lock buckles and high-temperature resistant sealing rubber rings. When the sealing doors 4 on both sides are closed, the lock buckles and lock tongues are clamped together, and the high-temperature resistant sealing rubber rings can ensure that the sealing doors 4 are in a sealed state after closing. Since the lock tongues, lock buckles and high-temperature resistant sealing rubber rings belong to the prior art and are not the innovation of the utility model, they are not described in detail in this application.

[0035] In this embodiment, the sealing door 4, the inner tank 1 and the outer cover 30 of the furnace body are all made of high-temperature resistant composite materials, and a temperature sensor is arranged in the inner tank 1. The temperature sensor can record the temperature inside the inner tank 1 in real time and send a signal to the main control device, which then controls the size of the flame at the ignition port 22 to prevent the inner tank 1 from being too high or too low in temperature and affecting the processing efficiency. Since the main control system and related control methods belong to the prior art, they are not described in detail in this embodiment.

[0036] In this embodiment, an exhaust pipe 5 is provided on the outer cover 30 of the furnace body, and multiple groups of grid plates 50 are hinged on the exhaust pipe 5. The exhaust pipe 5 is used to discharge excessive exhaust gas generated by the combustion of gas to prevent excessive pressure inside the inner tank 1. Since multiple groups of grid plates 50 are stacked on each other and the two sides of the grid plates 50 are of different lengths, part of the airflow from the return air duct 34 to the wind chamber 33 will blow the grid plates 50 to flip and open the exhaust pipe 5, and the excess airflow will be discharged from the exhaust pipe 5 to balance the internal pressure of the aging furnace.

[0037] Compared with the prior art, the utility model provides an aging furnace for aluminum profiles with uniform heating. When the aluminum profiles need to be heated, the hot air flow blown by the circulating fan blades 32 will pass through the gaps between the stacked aluminum profiles, ensuring that the stacked aluminum profiles can be heated synchronously at the same time. The hot air passes through the gaps between the aluminum profiles and flows to the return air duct 34 under the guidance of the sealing door 4. The rectifying wing plates 35 in the return air duct 34 can increase the flow rate of the return hot air, thereby further improving the heating efficiency by increasing the flow rate.

[0038] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
