Description

Technical Field

[0001] This utility model relates to the field of ultra-white high-transparency rolled glass production technology, specifically a two-stage multi-purpose exhaust torch structure for a large-tonnage kiln. Background Technology

[0002] In the production of rolled photovoltaic glass, it is often necessary to replace the rolling mill because different sizes of raw glass are to be made or because there are quality problems such as stones, bubbles, and unevenness on the surface of the raw glass sheet. During the replacement of the rolling mill and the lip brick, using a blower gun connected to compressed air can make the glass near the annealing furnace area on the outside of the gate plate cool faster. At the same time, a blower gun should also be used before the lead plate to melt the solidified glass that has not been completely cleaned off at the lower edge of the gate plate and around it.

[0003] The commonly used flamethrower is made of a one-piece seamless steel pipe, which is prone to bending and deformation during the heating process. The flamethrower is made of round steel pipe, which is inconvenient to set up and easy to turn over. The flamethrower uses a one-piece steel pipe, which makes it impossible to control the degree of combustion separately.

[0004] According to the announcement number CN202379873U, a heating device for lip bricks and gates used in photovoltaic rolled glass production is characterized by comprising a support bracket and a detachable torch mounted on the support bracket. The torch includes a cavity (8), one end of which is closed and the other end is connected to a transition pipe (7). At least two torch heads (10) communicating with the cavity (8) are also installed on the cavity (8). Trial use has proven that after using the heating device of this invention, the heating time of the lip bricks and gates is reduced by half, greatly improving the heating efficiency. It can also be successfully used when changing lip bricks on the production line, and the surface temperature of the lip bricks is raised to 800℃ in 1 hour and 30 minutes.

[0005] The exhaust gun structure used in the heating device described above is prone to bending and deformation during the heating process. The exhaust gun is a round steel pipe, which is inconvenient to set up and easy to flip. The exhaust gun uses an integrated steel pipe, which makes it impossible to control the degree of combustion separately. Therefore, we need to propose a two-stage multi-purpose exhaust gun structure for large-tonnage kilns. Utility Model Content

[0024] The main pipe 1 is placed on the external support frame at the kiln channel outlet via the mounting device 4. The mounting device 4 supports both ends of the main pipe 1, preventing it from tipping over. The blind flange 7 seals the main pipe 1 and adjusts the gas flow on both sides of the main pipe 1 to control the combustion according to the actual situation.
