Description

Technical Field

[0001] This utility model relates to the field of constant temperature furnace technology for aluminum profiles, and in particular to a constant temperature mechanism for an aging strengthening furnace for aluminum profiles. Background Technology

[0002] A constant temperature furnace for aluminum profiles is a device used to maintain a constant temperature for aluminum profiles during processing. It is mainly used for strengthening, oxidizing, and coloring aluminum profiles. The temperature in the constant temperature furnace will vary depending on the specific processing technology, but it generally needs to be controlled within the range of 180℃ to 195℃.

[0003] Specifically, the aging temperature for ordinary curtain wall profiles, ordinary door and window profiles, and industrial profiles should be controlled within the range of 195℃±5℃, while the aging temperature for insulated curtain wall profiles and insulated door and window profiles should be controlled within the range of 180℃±3℃. All of them are removed from the furnace after 3 hours of heat preservation, and are generally cooled by blowing air with a fan for about 20 minutes immediately after being removed from the furnace.

[0004] Because the heating elements in aluminum profile constant temperature furnaces are generally installed at the bottom of the furnace or in other localized areas, the temperature distribution is uneven when the aluminum profiles first enter the furnace, as the furnace has just started heating. This results in some areas at the bottom of the furnace being hotter than others.

[0005] Uneven furnace temperature, with localized overheating or undercooling, not only fails to effectively strengthen the aluminum profiles but may also have adverse effects over time. Furthermore, it takes time for the furnace temperature to become uniform, thus reducing work efficiency. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a constant temperature mechanism for an aluminum profile aging strengthening furnace, so as to solve the problem of uneven temperature distribution when the aluminum profile constant temperature furnace is first started in the prior art.

[0007] To achieve the above objectives, this utility model provides a temperature control mechanism for an aluminum profile aging strengthening furnace, comprising a temperature control furnace body for aging strengthening aluminum profiles, and the temperature control mechanism further comprising:

[0008] A vertical cylinder is fixedly connected to the top of the constant temperature furnace body. Several vertical cylinders are provided, and each vertical cylinder contains a fan blade. The side wall of the constant temperature furnace body is also provided with a drive component for driving the fan blade to rotate.

[0009] A connecting compartment is fixedly connected to the top of the constant temperature furnace body. The connecting compartment is connected to the vertical cylinder. A venting square pipe is also fixedly connected to the inner wall of the constant temperature furnace body. The lower end of the venting square pipe is located at the bottom of the constant temperature furnace body, and the upper end of the venting square pipe is connected to the connecting compartment.

[0010] Furthermore, the top of the constant temperature furnace body is also provided with a through hole, through which the connecting chamber and the ventilation square pipe are connected, and the outer end of the connecting chamber is open.

[0011] Furthermore, a cover plate is provided at the outer end opening of the connecting compartment, and a telescopic rod is fixedly connected to the inner end face of the cover plate. The other end of the telescopic rod is fixedly connected to the output shaft of the telescopic motor, and the telescopic motor is fixedly connected to the top of the constant temperature furnace body.

[0012] Furthermore, the connecting compartment is also provided with an L-shaped plate for opening or blocking the through hole. The L-shaped plate is slidably connected in the connecting compartment and is also fixedly connected to the telescopic rod.

[0013] Furthermore, the upper end of the vertical cylinder is closed, the lower end is open, and an air inlet is provided on the side wall of the vertical cylinder. The connecting chamber is connected to the vertical cylinder through the air inlet.

[0014] Furthermore, a horizontal bar is fixedly connected to the lower end of the square tube. The horizontal bar is a brick piece with an opening at the bottom, and the horizontal bar is connected to the square tube.

[0015] Furthermore, the distance between the L-shaped plate and the cover plate is greater than the length of the through hole. When the cover plate blocks the outer end opening of the connecting compartment, the L-shaped plate releases the through hole. When the L-shaped plate blocks the through hole, the cover plate releases the outer end opening of the connecting compartment.

[0016] Furthermore, the bottom of the side wall of the constant temperature furnace body is provided with an opening, and a movable baffle is provided at the opening. The movable baffle is rotatably connected to the outer side wall of the constant temperature furnace body.

[0017] The beneficial effects of this utility model are as follows: 1. By setting up a vertical cylinder and installing a fan blade inside the cylinder, and using a drive component to drive the fan blade to rotate, air convection is generated inside the constant temperature furnace, which effectively allows the exchange of hot air in some areas with cold air in others. This makes the temperature inside the constant temperature furnace quickly become uniform, avoiding local overheating or overcooling. This not only improves the strengthening effect on aluminum profiles but also increases work efficiency.

[0018] 2. The space inside the vertical cylinder is connected to the venting square tube, and the bottom end of the venting square tube is located at the bottom of the constant temperature furnace body. Therefore, for conventional constant temperature furnaces that install heating elements at the bottom, this design allows for direct heat exchange between the hottest part of the furnace bottom and the coldest part of the furnace top, further improving heat exchange efficiency and making the temperature inside the furnace body more uniform more quickly.

[0019] 3. The inner cavity of the vertical cylinder can also be connected to the external atmosphere. The switching method is achieved through an L-shaped plate and a cover plate. At the same time, an opening is set at the bottom of the side wall of the constant temperature furnace body, and a movable baffle is rotatably connected to the opening. After the aluminum profile is strengthened and removed, the source of ventilation of the vertical cylinder can be switched from internal ventilation to external ventilation. Ventilation and dust removal can then be achieved by opening the movable baffle at the bottom. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, since the heating elements in conventional aluminum profile constant temperature furnaces are generally installed at the bottom of the furnace, the temperature distribution is uneven when the aluminum profile first enters the furnace, as the furnace has just started heating. This results in localized areas of higher temperature at the bottom of the furnace and lower temperatures in other areas. This uneven temperature distribution, with localized overheating or undercooling, does not effectively strengthen the aluminum profile. Furthermore, waiting for the furnace temperature to naturally become uniform takes a long time, reducing work efficiency. Therefore, this invention designs a vertical cylinder 103, and installs a fan blade inside the cylinder 103 to drive airflow within the constant temperature furnace body 101, achieving rapid air convection heat exchange and quickly making the temperature within the constant temperature furnace body 101 uniform.

[0030] Specifically, several vertical cylinders 103 are provided and fixedly connected to the top of the constant temperature furnace body 101. A drive component for rotating the fan blades is also provided on the side wall of the constant temperature furnace body 101. A connecting chamber 104 is also fixedly connected to the top of the constant temperature furnace body 101, communicating with the vertical cylinders 103. A ventilation square pipe 111 is also fixedly connected to the inner wall of the constant temperature furnace body 101, with its lower end located at the bottom of the constant temperature furnace body 101 and its upper end communicating with the connecting chamber 104.

[0031] Specifically, a horizontal bar 112 is fixedly connected to the lower end of the square tube 111. The horizontal bar 112 is a brick piece with an opening at the bottom, and the horizontal bar 112 is connected to the square tube 111.

[0032] The upper end of the vertical cylinder 103 is closed and the lower end is open. An air inlet 110 is also provided on the side wall of the vertical cylinder 103. The connecting chamber 104 is connected to the vertical cylinder 103 through the air inlet 110.

[0033] Therefore, this invention uses a drive component to rotate the fan blades, generating air convection within the constant-temperature furnace body 101. This effectively allows for the exchange of hot air in certain areas with cold air in others. This results in a rapid and uniform temperature distribution within the furnace body 101, preventing localized overheating or undercooling. This not only improves the strengthening effect on aluminum profiles but also increases work efficiency.

[0034] Preferably, the top of the constant temperature furnace body 101 is also provided with a through hole 109, through which the connecting chamber 104 and the venting square pipe 111 communicate, and the outer end of the connecting chamber 104 is open. A cover plate 105 is provided at the outer end opening of the connecting chamber 104 to block the outer end opening of the connecting chamber 104. Therefore, for a conventional constant temperature furnace with the heating element installed at the bottom, this design allows the hottest part of the constant temperature furnace bottom to directly exchange heat with the coldest part of the constant temperature furnace body 101, further improving heat exchange efficiency and making the temperature inside the constant temperature furnace body 101 more uniform more quickly.

[0035] The second aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 4 As shown, a cover plate 105 is provided at the outer end opening of the connecting chamber 104. A telescopic rod 107 is fixedly connected to the inner end face of the cover plate 105. The other end of the telescopic rod 107 is fixedly connected to the output shaft of the telescopic motor 106, and the telescopic motor 106 is also fixedly connected to the top of the constant temperature furnace body 101.

[0036] In addition, an L-shaped plate 108 is provided in the connecting compartment 104 for opening or blocking the through hole 109. The L-shaped plate 108 is slidably connected in the connecting compartment 104, and the L-shaped plate 108 is also fixedly connected to the telescopic rod 107.

[0037] The distance between the L-shaped plate 108 and the cover plate 105 is greater than the length of the through hole 109. When the cover plate 105 blocks the outer end opening of the connecting chamber 104, the L-shaped plate 108 opens the through hole 109. When the L-shaped plate 108 blocks the through hole 109, the cover plate 105 opens the outer end opening of the connecting chamber 104.

[0038] Preferably, an opening is provided at the bottom of the side wall of the constant temperature furnace body 101, and a movable baffle 113 is provided at the opening. The movable baffle 113 is rotatably connected to the outer side wall of the constant temperature furnace body 101. The driving component for driving the movable baffle 113 to rotate is also provided on the constant temperature furnace body 101 (not shown in the figure).

[0039] Therefore, the L-shaped plate 108 and the cover plate 105 are moved by the telescopic motor 106 to open and close the through hole 109 and the outer end opening of the connecting chamber 104, thereby switching the air intake source of the vertical cylinder 103 between external and internal air intake. This allows the vertical cylinder 103 to still communicate with the outside atmosphere. The switching is achieved through the L-shaped plate 108 and the cover plate 105. At the same time, an opening is provided at the bottom of the side wall of the constant temperature furnace body 101, and a movable baffle 113 is rotatably connected to this opening. After the aluminum profile is strengthened and removed, the nearest air source of the vertical cylinder 103 can be switched from internal ventilation to external ventilation, and ventilation and dust removal can be achieved by opening the movable baffle 113 at the bottom.

[0040] In summary, this invention, by setting up a vertical cylinder 103 and installing a fan blade inside the cylinder 103, and using a drive component to rotate the fan blade, generates air convection within the constant temperature furnace body 101, effectively exchanging hot air in some areas with cold air in others. This allows the temperature within the constant temperature furnace body 101 to quickly become uniform, avoiding localized overheating or undercooling. This not only improves the strengthening effect on aluminum profiles but also increases work efficiency. The space within the vertical cylinder 103 is connected to the ventilation square pipe 111, and the bottom end of the ventilation square pipe 111 is located at the bottom of the constant temperature furnace body 101. Therefore, compared to conventional constant temperature furnaces that install heating elements at the bottom, this design allows direct heat exchange between the hottest part of the furnace bottom and the coldest part of the furnace body 101, further improving heat exchange efficiency and making the temperature within the furnace body 101 become uniform more quickly. Furthermore, the inner cavity of the vertical cylinder 103 can be connected to the external atmosphere. The switching method is achieved through the L-shaped plate 108 and the cover plate 105. At the same time, an opening is provided at the bottom of the side wall of the constant temperature furnace body 101, and a movable baffle 113 is rotatably connected to this opening. After the aluminum profile is strengthened and removed, the nearest source of ventilation in the vertical cylinder 103 can be switched from internal ventilation to external ventilation. Ventilation and dust removal can then be achieved by opening the movable baffle 113 at the bottom.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
