[0019] The present utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0020] Please refer to Figures 1-5 , a decentralized convection system for a glass tempering furnace, including two oppositely arranged convection air box bodies 1. An air inlet 21 is provided above the convection air box body 1. Corresponding air outlets 31 are provided on the opposite sides of the two convection air box bodies 1. A wind pipe 4 is provided between the two air outlets 31. A plurality of air outlet holes 41 are evenly arranged on the bottom circumference of the wind pipe 4. The air flow enters the convection air box body 1 from the air inlet 21 and then is discharged from the air outlet holes 41.

[0021] Wherein a convection fan 5 is provided at the air inlet 21 of the convection air box body 1. The convection fan 5 blows the air flow into the convection air box body 1, so that the air flow passes through the convection air box body 1 and the wind pipe 4 and is finally discharged from the air outlet holes 41.

[0022] In the solution of the present utility model, one end of the wind pipe 4 is sealed, and the other end is communicated with one of the convection air box bodies 1 at the air outlet 31. Both ends of the wind pipe 4 are fixed in the air outlet 31.

[0023] That is to say, the open end of the wind pipe 4 is communicated with one of the convection air box bodies 1 at the air outlet 31, and the sealed end of the wind pipe 4 is fixed in the opposite air outlet 31; or it can be understood that the air outlet 31 is provided for installing and erecting the wind pipe 4.

[0024] In addition, the opening directions of every two adjacent wind pipes 4 are opposite. Please refer to Figure 5 , Figure 5 again, where the arrow direction indicates the air flow direction, so that every two adjacent wind pipes 4 are communicated with different convection air box bodies 1. At this time, the convection is dispersed, reducing the pressure and flow loss of the air flow and making the air flow more uniform.

[0025] In this embodiment, the convection air box body 1 includes an upper cover body 2 and a stainless steel pipe 3 below the upper cover body 2. The upper cover body 2 is hermetically connected to the stainless steel pipe 3. The air inlet 21 is provided above the upper cover body 2. A plurality of air inlet distribution ports 32 are arranged on the top circumference of the stainless steel pipe 3. The air inlet 21 and the air outlet 31 are communicated through the air inlet distribution ports 32.

[0026] During use, the convection fan 5 first blows the air flow into the upper cover body 2, then the air flow passes through the air inlet distribution ports 32 and enters the stainless steel pipe 3, and then is discharged from the air outlet 31. The air inlet distribution ports 32 are evenly arranged on the stainless steel pipe 3, which can also play a role in air flow distribution and further improve the uniform flow of the air flow.

[0027] Please refer toFigure 4 , every two convection air box bodies 1 are evenly arranged in a straight line, and after being evenly arranged, they are integrally installed in the furnace.

[0028] In this embodiment, the upper cover body 2, the stainless steel pipe 3, the air duct 4, etc. are all made of stainless steel metal material.

[0029] The overall volume of the decentralized convection system of this glass tempering furnace is relatively small, which is convenient for arranging in the furnace, and can reduce the fluid pressure and flow loss during use, making the air flow more uniform and meeting the use requirements.

[0030] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
