Description

A continuous aluminum aging furnace Technical Field

[0001] This utility model relates to the technical field of aluminum processing equipment, specifically a continuous aluminum aging furnace. Background Technology

[0002] The main function of an aging furnace is to improve the properties of aluminum materials through heating and holding. It can significantly increase the hardness and strength of the material while maintaining good toughness and corrosion resistance.

[0003] Chinese Patent No. CN221759926U discloses an aluminum hardening and aging furnace. This utility model, by setting up an auxiliary device, facilitates uniform heating of the aging furnace. It can effectively reduce the problem that existing aluminum hardening and aging furnaces mainly rely on inputting hot air and blowing it onto the surface of the aluminum material through an overhead fan. However, during the heating process, the bottom may not be able to contact the hot air, resulting in uneven heating and affecting the aging effect. This improves the overall usability of the equipment.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: after the aluminum materials on the rack are heated, they still need to occupy the furnace body and use the heat dissipation device for air cooling, which affects the aging treatment of the next batch of aluminum materials and reduces the aging efficiency of the aluminum materials. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a continuous aluminum aging furnace.

[0006] The technical solution of this utility model is as follows: A continuous aluminum aging furnace includes a furnace body with four adjustable doors that divide the furnace interior into a preheating chamber, a heating chamber, and a cooling chamber; two sets of tracks installed at the bottom of the furnace body, with a mounting rack slidably connected between them; a heating mechanism located in the heating chamber; a preheating mechanism consisting of a first air supply component and a first exhaust pipe installed in the preheating chamber; the first air supply component consisting of a moving pipe that reciprocates horizontally along the preheating chamber and a first telescopic flexible hose installed at the top of the moving pipe; the top of the first telescopic flexible hose being connected to the first exhaust pipe, and the other end of the first exhaust pipe being connected to the heating chamber; multiple sets of air nozzles evenly installed on the inner wall of the moving pipe; a dust extraction mechanism installed at the exhaust port of the preheating chamber; and a cooling mechanism located in the cooling chamber.

[0007] Preferably, the placement rack is composed of multiple sets of support rods spliced ​​together along the horizontal, vertical and longitudinal directions, with gaps between adjacent support rods.

[0008] Preferably, a drive mechanism is provided between the placement frame and the track. The drive mechanism includes a mounting base installed at the bottom of the placement frame, with a movable wheel at the bottom of the mounting base, the movable wheel being rolledly connected to the bottom of the track; a toothed plate installed at the bottom of the threaded rod; and a gear driven to rotate by a motor installed on the mounting base, the gear meshing with the toothed plate.

[0009] Preferably, the preheating chamber is provided with a threaded rod and multiple sets of guide seats. The threaded rod is driven to rotate by a motor installed on the inner wall of the furnace. The guide seats are installed on the inner wall of the furnace. Multiple sets of lugs are provided on the moving tube. The lugs are threadedly connected to the threaded rod or slidably connected to the guide seats.

[0010] Preferably, the cooling mechanism consists of a second air supply assembly and a second fan mounted on the furnace body. The second air supply assembly has the same structure as the first air supply assembly, and the second fan is connected to the second air supply assembly via a second telescopic flexible hose.

[0011] Preferably, a second exhaust duct is installed at the exhaust port of the cooling chamber, and the other end of the second exhaust duct is connected to the preheating chamber. A T-shaped pipe is also installed on the second exhaust duct, and a solenoid valve is installed at both output ends of the T-shaped pipe.

The second exhaust pipe can recover the hot air generated by the cooling mechanism to preheat the aluminum material, thus avoiding resource waste and improving the aluminum material processing efficiency.

[0018] Example 1

[0019] As shown in Figures 1 to 4, the present invention discloses a continuous aluminum aging furnace, comprising a furnace body 1, rails 103, a heating mechanism, a preheating mechanism, and a cooling mechanism. Four sets of doors 102 are adjustablely installed on the furnace body 1. The doors 102 are driven by lifting components 101 installed on the side wall of the furnace body 1, which slide along the height of the furnace body 1. The lifting components 101 are hydraulic rods. The four sets of doors 102 divide the inner cavity of the furnace body 1 into a preheating chamber, a heating chamber, and a cooling chamber. Two sets of rails 103 are provided, installed at the bottom of the furnace body 1, and a mounting frame 2 is slidably connected between the two sets of rails 103. The heating mechanism is located in the heating chamber and is powered by a hot air supply device 6 installed on the furnace body 1 and an output device connected to the hot air supply device 6. The preheating mechanism consists of a first air supply component and a first exhaust pipe 401 installed in the preheating chamber. The first air supply component consists of a moving pipe 302 that moves back and forth along the horizontal direction of the preheating chamber and a first telescopic hose 4 installed at the top of the moving pipe 302. The top of the first telescopic hose 4 extends to the outside of the top of the furnace body 1 and connects to the first exhaust pipe 401. The other end of the first exhaust pipe 401 is connected to the heating chamber. A first fan is installed on the first exhaust pipe 401 to accelerate the circulation of hot air. The moving pipe 302 is C-shaped and multiple sets of air nozzles are evenly installed on the inner wall of the moving pipe 302. A dust collection mechanism 5 is installed at the exhaust port of the preheating chamber. The cooling mechanism is installed in the cooling chamber.

[0020] Furthermore, the placement rack 2 is composed of multiple sets of support rods spliced ​​together along the horizontal, vertical and longitudinal directions, with gaps between adjacent support rods to facilitate full contact between hot air and the aluminum material placed on the placement rack 2.

[0021] Furthermore, a drive mechanism is provided between the placement frame 2 and the track 103. The drive mechanism includes a mounting base 201, a toothed plate 203, and a gear 202. The mounting base 201 is installed at the bottom of the placement frame 2, and a moving wheel 204 is provided at the bottom of the mounting base 201. The moving wheel 204 is rolledly connected to the bottom of the track 103, and the track 103 is U-shaped. The toothed plate 203 is installed at the bottom of the threaded rod 3. The gear 202 is driven to rotate by a motor installed on the mounting base 201, and the gear 202 is meshed with the toothed plate 203.

[0022] Furthermore, the preheating chamber is equipped with a threaded rod 3 and multiple sets of guide seats 301. The threaded rod 3 is driven to rotate by a motor installed on the inner wall of the furnace body 1. The guide seats 301 are installed on the inner wall of the furnace body 1. Multiple sets of ear seats 303 are provided on the moving tube 302. The ear seats 303 are threadedly connected to the threaded rod 3 or slidably connected to the guide seats 301.

[0023] Furthermore, the cooling mechanism consists of a second air supply assembly and a second fan 7 installed on the furnace body 1. The second air supply assembly has the same structure as the first air supply assembly, and the second fan 7 is connected to the second air supply assembly through a second telescopic flexible hose.

[0024] In this embodiment, the hot air supply device 6 is activated to deliver hot air into the diversion pipe 601 and spray it out through multiple sets of air outlet pipes to preheat the heating chamber. The controller activates the lifting component 101 to drive the door 102 of the preheating chamber inlet upward, placing multiple sets of aluminum materials on the placement rack 2. The placement rack 2 is moved to the track 103 by the sets of moving wheels 204 at the bottom of the placement rack 2 until the multiple sets of moving wheels 204 are inside the track 103. The controller activates the motor to drive the corresponding sets of gears 202 to rotate. The gears 202 mesh with the toothed plates 203, thereby moving the placement rack 2 horizontally along the track 103 to place the aluminum materials. The aluminum material placement rack 2 moves into the preheating chamber of the furnace body 1 and closes the door 102 of the preheating chamber inlet. At this time, the hot air in the heating chamber is delivered to the moving pipe 302 along the first exhaust pipe 401 and the first telescopic hose 4. The motor is started by the controller to drive the threaded rod 3 to rotate clockwise and counterclockwise alternately. Under the guidance of the guide seat 301, the moving pipe 302 moves back and forth along the horizontal direction of the preheating chamber to preheat the aluminum material. At the same time, it can blow up the aluminum powder and other impurities attached to the aluminum material. The dust collection mechanism 5 absorbs the impurities in the preheating chamber and discharges the exhaust gas to avoid the impurities interfering with the processing of the aluminum material during the subsequent heating process.

[0025] After the aluminum material in the placement rack 2 is preheated, the door 102 at the discharge end of the preheating chamber is opened upwards, and then closed after the placement rack 2 moves into the heating chamber. At this time, a new set of placement racks 2 can continue to move towards the preheating chamber for preheating, while the aluminum material on the placement rack 2 in the heating chamber is officially heated.

[0026] After heating is complete, the door 102 at the discharge end of the heating chamber is opened upwards. After the placement rack 2 moves to the cooling chamber, it is closed. At this time, the second fan 7 is started to deliver cooling air to the second air supply assembly to cool the aluminum material on the placement rack 2. The cooled gas is discharged along the exhaust port of the cooling chamber. The other set of placement racks 2, which has been preheated, can be moved to the heating chamber for heating. This process is repeated, which improves the continuity of aluminum material processing and increases processing efficiency.

[0027] Example 2

[0028] As shown in Figures 1 and 4, the continuous aluminum aging furnace proposed in this utility model, compared with Embodiment 1, has a second exhaust pipe 402 installed at the exhaust port of the cooling chamber. The other end of the second exhaust pipe 402 is connected to the preheating chamber. A third fan is installed on the second exhaust pipe 402. A three-way pipe 403 is also installed on the second exhaust pipe 402. Solenoid valves are installed at both output ends of the three-way pipe 403. A temperature sensor is installed near the input end of the second exhaust pipe 402.

[0029] In this embodiment, the cold air is heated into hot air after it comes into full contact with the high-temperature aluminum material. The hot air flows back to the preheating chamber along the second exhaust pipe 402 to preheat the new aluminum material, thus avoiding heat waste. When the temperature sensor at the inlet end of the second exhaust pipe 402 detects that the temperature has dropped to the set threshold, the controller opens or closes the valve port of the solenoid valve corresponding to the three-way pipe 403, so that the air in the cooling chamber no longer flows back to the preheating chamber along the second exhaust pipe 402, but is discharged along the other set of output ends of the three-way pipe 403, thus avoiding the air with a lower temperature from interfering with the preheating of the aluminum material in the preheating chamber.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
