[0002] Currently, compressed gas is used in the furnace to uniformly distribute the temperature, which requires high on-site gas pressure. Unstable on-site pressure has a certain impact on the gas inside the furnace and may even cause batch loss of glass. In the current glass cooling process, fans are used to cool the glass, but the residual pressure of the fans is not utilized, resulting in energy waste.

[0003] The applicant discovered through a search that Chinese patent document CN217895461U, published on November 25, 2022, discloses a feeding device and a tempering furnace system for a tempering furnace. The feeding device for the tempering furnace includes a conveying shell arranged at an angle to the horizontal plane.

The feeding device for the tempering furnace also includes a conveying mechanism disposed within the conveying shell, which is configured to transport the material entering through the inlet to the outlet. However, this device also fails to solve the aforementioned technical problem.

[0004] Therefore, in order to improve or solve at least one of the above problems, it is necessary to provide a tempering furnace gas pressure balancing device that can use the residual pressure of the glass cooling fan to balance the gas pressure in the tempering furnace. Utility Model Content

[0048] In this invention, the gas cooled by the glass cooling fan enters the air box 2, and the gas in the air box 2 enters the gas distribution tank 1 through the gas delivery pipe 3. The gas distribution tank 1 inputs the gas into the tempering furnace through multiple evenly arranged first connecting sleeves 8 and second connecting sleeves 9, thereby balancing the gas pressure in the tempering furnace. When the gas pressure in the tempering furnace is lower or higher than the working pressure, the operator adjusts the amount of gas input into the tempering furnace through the pressure regulating component, thereby ensuring that the gas pressure in the tempering furnace reaches the working pressure and remains stable. When the glass stops entering the tempering furnace, the gas pressure automatically stops outputting after the glass has finished passing through, and the temperature inside the tempering furnace quickly reaches the set value.
