Description

Technical Field

[0001] The utility model relates to the technical field of double-chamber tempering furnaces, and in particular to a convection flat-bent double-chamber tempering furnace for tempered glass production. Background Art

[0002] A double-chamber tempering furnace is a heat treatment device that increases the strength and hardness of an object by high temperature and rapid cooling. It is particularly suitable for strengthening glass. It uses two adjacent heating chambers, one with a flat air grille and the other with a curved air grille. Connected to these air grilles is a static pressure box, which is connected to the high-pressure fan and the low-pressure fan through the high-pressure air duct and the low-pressure air supply duct respectively. The working principle of the double-chamber tempering furnace is to heat the glass to a high temperature state and then cool it rapidly, so that a pressure difference is generated between the surface and the inside of the glass, thereby increasing its strength and durability. This rapid cooling process is usually achieved by spraying a cooling medium (such as air or inert gas) on the surface of the glass.

[0003] The patent specification with announcement number CN210001766U discloses an energy-saving double-chamber convection tempered glass processing tempering furnace, including a tempered cooling furnace and a lower plate table, wherein the lower plate table is fixedly installed at the left position of the lower end of the tempered cooling furnace, the first heating furnace is fixedly installed at the right end of the tempered cooling furnace, the second heating furnace is fixedly installed at the right end of the first heating furnace, and an elastic support seat is installed at the lower end of the support rod by welding. By laying a full heat-resistant steel inner tank, the scouring of the insulation cotton caused by the wind circulation in the furnace and the falling of dust particles can be prevented, thereby improving the surface quality of the glass. By arranging a spiral filament heater, the heater has a larger heat exchange area, ensuring high heat transfer efficiency and shortening the heating time of the glass.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for cleaning the filter on the top of the tempering furnace fan blade during use, because the fan blade needs to continuously introduce external air to blow the material during use, so if the filter is blocked, it is not convenient to disassemble. The staff needs to unscrew several bolts to disassemble it, which is not convenient for actual use. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a convection flat-bent double-chamber tempering furnace for tempered glass production, which solves the problem in the related art that it is inconvenient to conveniently disassemble and assemble the filter screen.

[0006] The technical solution of the utility model is as follows:

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1~Figure 4 As shown, this embodiment proposes a convection flat-bending double-chamber tempering furnace for tempered glass production, including a body 1, protective shells 2 are fixedly connected to both sides of the top of the body 1, pulling plates 3 are provided inside the two protective shells 2, clamping grooves are provided inside the two pulling plates 3, filters 4 are embedded inside the two pulling plates 3, connecting grooves are provided on both sides of the top of the body 1, fixing plates 6 are fixedly connected to both side walls of the inner cavity of the two connecting grooves, a rotating shaft 8 is fixedly connected between the two fixing plates 6, a driving member 7 is fixedly connected to the top of the rotating shaft 8, and a fan blade 9 is fixedly connected to the bottom of the driving member 7 through an output shaft.

[0027] In this embodiment, the pulling plates 3 extend into the interior of the protective shell 2 and are in contact with the protective shell 2 . A pulling rod 5 is fixedly connected to one side of the top of the two pulling plates 3 , so that the pulling plates 3 can be pulled to move.

[0028] In this embodiment, positioning plates 10 are fixedly connected to both sides of the exterior of the body 1 , and shells 11 are fixedly connected to both sides of the tops of the two positioning plates 10 , which can facilitate the fixing of the shells 11 .

[0029] In this embodiment, the bottom of the inner cavity of the two shells 11 is fixedly connected with a spring 12, and the top of the two springs 12 is fixedly connected with a sliding column 13, which can facilitate the fixed connection of the spring 12.

[0030] In this embodiment, the sliding post 13 is in contact with the outer surface of the housing 11 , and the sliding post 13 passes through the clamping groove and is in contact with the clamping groove, which can facilitate the sliding work of the sliding post 13 .

[0031] In this embodiment, the two sliding columns 13 are both fixedly connected with connecting blocks 14 on their exteriors, and a connecting plate 15 is fixedly connected between the two connecting blocks 14 , which can facilitate the fixing of the connecting blocks 14 .

[0032] When it is necessary to blow air, the staff needs to turn on the driving member 7. After turning on, the driving member 7 will synchronously drive the rotating shaft 8 to rotate. During the rotation process, the rotating shaft 8 will synchronously drive the fan blades 9 to rotate. At this time, the external air will be introduced into the interior of the machine body 1 through the rotation of the fan blades 9 for blowing air. If a large amount of impurities adhere to the outer surface of the filter screen 4 after long-term use, the staff needs to move the connecting plate 15 downward. During the movement, the connecting plate 15 will synchronously drive the connecting block 14 and the sliding column 13 to press downward. During this process, the spring 12 will be compressed. Then, when the sliding column 13 leaves the inside of the pulling plate 3, the staff can take out the pull rod 5. After being taken out, the pull rod 5 will synchronously drive the pulling plate 3 to move. During the movement process, the pulling plate 3 will synchronously drive the filter screen 4 to move, which can facilitate the staff to clean it. During this process, the filter screen 4 will be separated from the driving member 7 to facilitate the cleaning work.

[0033] When the staff needs to install the pulling plate 3, they just need to insert the pulling plate 3 into the filter screen 4 and slide it, and then insert the sliding column 13 through the inside of the clamping groove again.

[0034] Example 2

[0035] like Figure 3As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that both sides of the bottom of the pulling plate 3 are fixedly connected with bottom plates 16, and one side of the two bottom plates 16 is provided with a spring 2 17, and the two springs 2 17 are respectively in contact with one side of the two bottom plates 16, which can facilitate the movement of the bottom plates 16.

[0036] In this embodiment, the two springs 17 are fixedly connected to the two sides of the exterior of the protective shell 2 , respectively, and the bottom of the bottom plate 16 is in contact with the top of the body 1 .

[0037] During the disassembly process, when the sliding column 13 leaves the inside of the card slot, the spring 2 17 will quickly stretch and drive the bottom plate 16 to move outward. During the movement, the bottom plate 16 will simultaneously drive the pulling plate 3 to move outward, so that it is convenient for the staff to remove the pulling plate 3 and pull it out as a whole. If the pulling plate 3 is installed and reset again, the bottom plate 16 will squeeze and compress the spring 2 17 to facilitate the subsequent pop-up.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
