Description

Technical Field

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

[0002] The aluminum alloy aging furnace is an energy-saving periodic operation furnace, mainly used for aging heat treatment of aluminum alloy castings, aluminum alloy die castings, aluminum alloy wheels, aluminum profiles and wires, aluminum alloy plates, aluminum alloy mesh plates, pistons, etc., under high and uniform temperature conditions.

[0003] However, existing aluminum profile aging furnaces cannot effectively circulate hot air inside them, and due to the uneven distribution of hot air flow, the temperature difference inside the aging furnace is large, which easily leads to uneven heating of the aluminum profile and fails to meet the working requirements of aluminum profile aging furnaces. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hot air circulating aging furnace for aluminum profile processing, which solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hot air circulating aging furnace for aluminum profile processing includes an aging furnace body, a feeding trolley, and an air inlet assembly. The bottom of the aging furnace body is provided with a base, and a material inlet is opened on the front of the furnace body. Symmetrical furnace doors are hinged to the front of the material inlet, and a handle is provided in the center of the front of each furnace door. A control panel is provided at the lower front of one of the furnace doors, next to the handle. Symmetrical connecting blocks are provided at the top of the interior of the aging furnace body, and an inner furnace body is provided at the bottom of the connecting blocks. A heating chamber is provided between the inner wall of the aging furnace body and the outer wall of the inner furnace body. Several first air inlets are opened at the top of the inner furnace body, and air inlets are provided on both sides of the inner furnace body. The furnace has several second air inlets and several air outlets at the bottom of the inner furnace body. An inclined plate is provided at the lower front of the aging furnace body. Slide grooves are provided at the bottom of the inner furnace body and the top of the inclined plate. A feeding cart is slidably connected to the slide grooves. Exhaust fans are provided at the middle of both sides of the aging furnace body. An air inlet pipe is installed at the input end of the exhaust fan. The other end of the air inlet pipe is installed through the bottom of the aging furnace body. An air outlet pipe is installed at the output end of the exhaust fan. The other end of the air outlet pipe is installed through the top of the aging furnace body. Symmetrical heating resistance wires are provided inside the air outlet pipe. An air inlet assembly is provided at the center of the top of the aging furnace body.

[0007] Preferably, the feeding cart includes a base plate, the bottom end of which is provided with symmetrical casters, the casters being slidably connected to a chute, the top end of which is provided with symmetrical fixing rods, the top end of which is provided with a connecting plate, the number of connecting plates being set to two, and the surface of the connecting plates having a plurality of ventilation holes.

[0008] Preferably, the air intake assembly includes an air intake duct, which is in the shape of a through hole. A removable dust filter is provided at the upper end of the air intake duct. A support plate is provided at the middle of the air intake duct. An exhaust fan is provided at the bottom end of the support plate. A heating rod is provided inside the air intake duct and below the exhaust fan. The exhaust fan faces the heating rod. The control panel is electrically connected to the exhaust fan and the heating rod.

[0010] Preferably, the control panel, the exhaust fan, and the heating resistance wire are all electrically connected.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] The hot air circulating aging furnace for aluminum profile processing provided by this utility model can simultaneously start the exhaust fan and heating rod through the control panel. The exhaust fan delivers the air filtered by the dust filter to the air inlet duct. The filtered air is then heated by the heating rod and delivered to the heating chamber. It then enters the interior of the furnace body through the first and second air inlets, thereby heating the aluminum profiles in the feeding cart. The exhaust fan is then started through the control panel, drawing the hot air from the furnace body to the air inlet pipe through the air outlet. The hot air is then delivered to the air outlet pipe through the air inlet pipe. The heating resistance wire is then started through the control panel, and the air becomes hot air again after being heated by the heating resistance wire. The hot air then enters the heating chamber and flows back into the furnace body through the first and second air inlets, thus effectively circulating the hot air within the aging furnace body.

[0013] This utility model provides a heating chamber between the inner wall and the outer wall of the aging furnace body. Several infrared heating plates are provided on both sides of the inner furnace body and inside the heating chamber, so that hot air can enter the inner furnace body from the top, left and right directions, thereby enabling uniform heating of the aluminum profiles in the feeding car.

[0014] This utility model features a feeding trolley. After hot air enters the inner furnace body, it is evenly sprayed onto the surface of the aluminum profile through several ventilation holes on the surface of the connecting plate, thus improving the aging effect on the aluminum profile.

[0026] Example 2:

[0027] As shown in the attached diagram of the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a hot air circulating aging furnace for aluminum profile processing is first connected to an external power supply. When in use, the aging furnace body 1 is started first, and then the aluminum profile to be aged is placed on the top of the connecting plate 9.3. Then, the feeding cart 9 is sent into the interior of the inner furnace body 10 through the slide 7, and the pull handle 3 is pushed to close the furnace door 2, thereby forming a sealed space inside the inner furnace body 10. Next, the exhaust fan 21.4 and the heating rod 21.5 are started simultaneously via the control panel 4. The exhaust fan 21.4 delivers the air filtered by the dust filter 21.2 to the air inlet duct 21.1. The filtered air is then heated by the heating rod 21.5 and delivered to the heating chamber 14.

[0028] This utility model features a feeding cart 9. After hot air enters the inner furnace body 10, it is evenly sprayed onto the surface of the aluminum profile through several ventilation holes 9.5 on the surface of the connecting plate 9.3, thus improving the aging effect on the aluminum profile.
