Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the drawings in the specification, and it should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a dilution air duct capable of adjusting air temperature includes: fan 10, main tuber pipe 1, branch tuber pipe 2, temperature adjustment mechanism and glass pond 9, glass pond 9 be the rectangular channel of upward open-ended, glass pond 9 top both sides are equipped with breastwork 8, the symmetry is equipped with air outlet 7 on the breastwork 8 of both sides, air outlet 7 outside all is connected with branch tuber pipe 2, two branch tuber pipes 2 other ends are connected with main tuber pipe 1, main tuber pipe 1 is connected with fan 10, fan 10 produced wind through main tuber pipe 1 and the air outlet 7 of 2 flow direction glass ponds 9 tops of branch tuber pipe for cool off the glass liquid in the glass pond 9, branch tuber pipe 2 on all be equipped with the temperature adjustment mechanism who is used for adjusting the wind temperature. The temperature adjusting mechanism comprises: cooling tube 3, water inlet 4, delivery port 5 and governing valve 6, cooling tube 3 around establishing on 2 outer walls of branch tuber pipe, both ends are equipped with water inlet 4 and delivery port 5 about cooling tube 3, are equipped with the governing valve 6 that is used for the regulating pondage in water inlet 4 end. The cooling pipe 3 is a metal coil pipe and is welded and fixed on the outer wall of the branch air pipe 2, the diameter of the cooling pipe is 30mm, and the height of the cooling pipe is 1 m.
Example (b): in a certain float glass production line, the situations of large dilution air quantity and asymmetric dilution air on two sides exist for a long time, and the optical deformation angle difference of a left plate and a right plate of a product is large.
Before modification, the diluted air volume is 900 standard cubic meters per hour, and the forming temperature is 1150 DEG C
Optical deformation angle of glass plate (4 mm as an example)
| Position of glass plate | Right board | Left board |
| Optical deformation angle (°) | 46 | 42 |
After the air pipe is transformed, the dilution air quantity is reduced. Because the left and right optical deformation angles have larger difference, the temperatures of the left and right dilution wind are judged to be inconsistent, the ambient temperature on the left side is 5-6 ℃ lower than that on the right side through field measurement, the water flow in the cooling pipe 3 on the left branch air pipe 2 is properly reduced through the regulating valve 6, and the data after 5 hours of stabilization are as follows.
The dilution air volume is 600 standard cubic meters per hour, and the molding temperature is 1150 DEG C
Optical deformation angle of glass plate (4 mm as an example)
| Position of glass plate | Right board | Left board |
| Optical deformation angle (°) | 48 | 47 |
It can be seen from the data that, after the dilution air volume is reduced and the dilution air temperature is adjusted, the overall optical deformation angle is improved, and the difference of the optical deformation angles of the left plate and the right plate is reduced.
