[0038] Working principle: in use, when the temperature inside the production furnace 1 is low, the air inside the heating furnace 2 is heated by the working of the heating pipe 3, so that the temperature inside the heating furnace 2 is increased, then the electromagnetic valve 5 and the air pump 6 are opened, so that the hot air inside the heating furnace 2 enters the inside of the production furnace 1 from the pipeline one 4, the temperature inside the production furnace 1 is increased, and the hot air entering the inside of the heating furnace 2 pushes out the air originally in the heating furnace 2 and enters the shell 9 from the pipeline two 7, so that the heat in the hot air is transferred to the water liquid in the shell 9, then the water liquid at the bottom of the shell 9 is pumped into the circulating pipe 11 by the working of the liquid pump 12, and is sent back to the top of the shell 9 to flow back to the inside of the shell 9, and the water liquid flowing in the circulating pipe 11 will transfer its heat to the air inside the heating furnace 2, so that the temperature of the air inside the heating furnace 2 is increased, so that the air inside the heating furnace 2 always has a certain temperature, reducing the time and energy consumption required for subsequent heating of the air by the heating pipe 3, so as to complete the recycling of energy, which is beneficial to the reduction of energy consumption in the process of mass production of glass, and reduces the production cost.

[0039] When the temperature inside the production furnace 1 is high, the cold air is sent into the inside of the production furnace 1 by the working of the cold air blower 13, and the power of the electric cylinder 24 is started, the electric cylinder 24 works to make the baffle 25 displace to the right, so that the through hole 14 is no longer blocked by the baffle 25, the cold air sent into the inside of the production furnace 1 by the cold air blower 13 pushes out the hot air originally in the production furnace 1 from the through hole 14, so as to cool down the inside of the production furnace 1, realizing the controllability of the temperature inside the production furnace 1 with high accuracy in the process of glass production.

[0040] When the filter plate 16 needs to be disassembled and replaced, the control rod 18 is pulled, the two sets of limiting rods 20 overcome the elastic force of the springs 21 to approach each other through the action of the pull rope 19, so that the limiting rods 20 are separated from the inside of the limiting slot 22, and the limiting effect on the filter plate 16 is removed, at this time, the filter plate 16 can be conveniently and quickly taken out from the inside of the insertion slot 17 for cleaning and replacement, and the filtering effect is improved.
