Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass manufacturing, in particular to an online cooling device for the cold end of a glass production line. Background Art
[0002] During float glass production, the annealing lehr cools the glass sheets from the exit temperature of the tin bath to a temperature suitable for cutting according to a predetermined cooling curve. In existing designs, the cold end does not require additional cooling devices to lower the glass temperature; the glass meets the cold end cutting requirements upon exiting the annealing lehr.
[0003] However, with the rapid development of the glass industry and robust market demand, glass producers are faced with the challenge of increasing production capacity without modifying existing production lines. Consequently, an increasing number of glass factories are facing the technical challenge of cold-rolling their production lines. To save costs, most customers require modifications that increase production without increasing the length of the annealing lehr. However, in this scenario, the temperature of the glass exiting the annealing lehr exceeds 70°C, making it difficult to cut the glass until it reaches the desired temperature at the cold end. This significantly impacts glass production efficiency.
[0004] Therefore, how to quickly cool down the glass leaving the kiln is an urgent problem that needs to be solved by those skilled in the art. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figures 1 to 7 The present invention provides a technical solution: an online cooling device for the cold end of a glass production line, comprising a mounting frame 1, on which is provided an onboard cooling assembly, which is located above a glass conveyor roller 100. The onboard cooling assembly comprises an onboard fan 2 and a plurality of onboard ventilation pipes 3 connected to the onboard fan 2. The onboard ventilation pipes 3 are provided with downwardly opening air outlets 4, which are trapezoidal flat structures. The bottom end of the air outlet nozzle 4 is provided with a downwardly protruding groove 5, the edge of the groove 5 being sealed to the lower edge of the air outlet nozzle 4, and a plurality of air outlet holes 6 being provided on both sides of the groove 5. During operation, the air generated by the onboard fan 2 is blown into the onboard ventilation pipe 3, passes through the air outlet nozzle 4, and is blown toward the conveyor roller 100 through the air outlet holes 6, thereby cooling the glass on the conveyor roller 100 and rapidly cooling the glass just out of the annealing furnace to a temperature that meets the cutting requirements.
[0023] Furthermore, to evenly cool the glass and shorten the cooling time, the present invention also includes an under-plate cooling assembly. This assembly is located below the glass conveyor roller 100 and includes an under-plate air duct 8 connected to a bellows 9, which is provided with a plurality of upwardly opening circular holes 10. While the under-plate cooling assembly cools the glass, it also blows air to cool the bottom surface of the glass. This improves cooling efficiency and evenly cools the top and bottom surfaces of the glass, preventing defects caused by uneven temperatures during cutting.
[0024] Furthermore, the ventilation pipes 3 on the board are arranged in groups of 6 vertically, and the wind boxes 9 are arranged in groups horizontally. In this way, the ventilation pipes 3 and the wind boxes 9 on the board are arranged in a crisscross pattern, which can cool the glass more comprehensively.
[0025] Furthermore, the bellows 9 includes a box body 91, an upper end of the box body 91 is provided with an upward protrusion 92, and circular holes 10 are evenly arranged on both sides of the protrusion. Wind blows out from the circular holes 10 and can be blown more evenly on the glass surface.
[0026] Furthermore, two sets of onboard fans 2 are provided, and the air outlets of the two sets of onboard fans 2 are connected to an air supply pipe 21, which is connected to the onboard ventilation pipe 3. The two sets of onboard fans 2 can provide a stronger blowing force, allowing the onboard ventilation pipe 3 to be as long as possible. The onboard ventilation pipe 3 can be made of pipes with flanges at both ends, allowing the onboard ventilation pipes 3 to be easily connected to each other and changed in length as needed.
[0027] Furthermore, the ventilation pipes 3 and the bellows 9 on the board are provided with manual valves, and the air output of each pipe and each bellows is adjusted by the manual valves.
[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
