Description

Technical Field

[0001] The utility model belongs to the technical field of glass production, and in particular relates to a glass edge cooling system based on an eddy current tube. Background Art

[0002] When producing float glass, a mixture of sand, limestone, dolomite, alkali, feldspar, sodium sulfate and carbon powder needs to be heated to 1500°C in a kiln to form a molten state, which is then directed to a tin bath. The tin bath uses an edge drawing machine to adjust the size and thickness of the glass. Since external force is used to adjust the glass, roller marks of the edge drawing machine will be left on both sides of the upper surface of the glass. In the sheet collection section, they need to be cut and cleared with a longitudinal cutter, and the bottom of the plate is prone to cracking during the edge cleaning process.

[0003] The reason for the bottom cracking is the stress imbalance on both sides of the glass. To adjust the stress here, the lower surface of the glass edges needs to be cooled to a certain extent. The current commonly used cooling method is to use compressed air to purge, but this cooling method is less effective. In addition, since the kiln works 24 hours a day, it needs to be purged and cooled continuously, which leads to high energy consumption when using compressed air to purge and cool down. Utility Model Content

[0004] The utility model aims to provide a glass edge cooling system based on a vortex tube, which effectively solves the problem that the current cooling method using compressed air blowing has poor effect.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A glass edge cooling system based on a vortex tube comprises a water tank, a vortex tube and a compressed air delivery pipeline located outside the water tank, and a wet roller and a compressed air heat exchange pipeline located inside the water tank. The water tank is filled with water, the compressed air heat exchange pipeline is immersed in the water, the lower roller surface of the wet roller is in contact with the water, and the upper roller surface of the wet roller is in contact with the lower surface of the side edge of the glass.

[0007] The wet roller is rotatably connected to the water tank via a rotating shaft, and the rotating direction of the wet roller is the same as the conveying direction of the glass.

[0008] The compressed air delivery pipeline is connected to the inlet of the vortex tube, the outlet of the vortex tube is connected to the inlet of the compressed air heat exchange pipeline, and the outlet of the compressed air heat exchange pipeline is connected to the air nozzle for cooling the lower surface of the downstream glass side edge through a hose.

[0009] Furthermore, the water tank is rectangular, and the upper part of the water tank is open.

[0010] Furthermore, the inlet and the outlet of the compressed air heat exchange pipeline are both arranged on the side wall of the water tank close to the edge of the glass conveying roller.

[0011] Furthermore, the compressed air heat exchange pipeline is spiral-shaped.

[0012] Furthermore, the water tank is supported by a bracket placed on the ground.

[0013] Furthermore, a left baffle and a right baffle arranged in parallel are fixed inside the water tank, and the left baffle and the right baffle are parallel to the left wall or the right wall of the water tank, and the two ends of the rotating shaft are respectively fixed on the left baffle and the right baffle.

[0014] Furthermore, the roller surface of the wet roller is made of rubber.

[0015] Compared with the prior art, the beneficial technical effects of the utility model are:

[0016] (1) The utility model realizes the diversion of cold and hot air flows in the compressed air by arranging a vortex tube between the compressed air delivery pipeline and the compressed air heat exchange pipeline, so that the cold air flow in the compressed air enters the compressed air heat exchange pipeline, thereby improving the heat exchange efficiency and improving the primary cooling effect of the wet roller on the glass.

[0017] (2) The utility model cools the glass once through a wet roller, and then cools the downstream glass twice through an air nozzle, which not only reuses the compressed air, but also improves the glass cooling effect, prevents the bottom of the board from cracking, and saves energy and reduces consumption.
