Description

TECHNICAL FIELD

[0001] The utility model relates to glass manufacturing technical field, concretely is a kind of glass light edge comprehensive cooling device and glass production system. BACKGROUND

[0002] In the process of producing and manufacturing float glass, after raw materials are melted in a melting furnace, the glass liquid is discharged from the melting furnace into a tin bath after exhausting bubble, homogenizing and clarifying, and then is formed, especially for the production of ultra-thin glass, the forming process is to thin the glass liquid by a edge machine, and the glass plate is drawn to a predetermined thickness and then is discharged from the tin bath to enter the annealing lehr through a transition roller for annealing treatment.

[0003] In the glass forming process, the thickness of the light edge on both sides of the glass plate is much greater than the thickness of the glass substrate, for example, for producing a glass substrate with a thickness of 0.33-1.1 mm, the thickness of the light edge on both sides reaches about 1.1-10 mm, due to the large thickness difference, there is a large deviation in stress relief during the annealing process in the annealing lehr, which seriously affects the cutting quality of the glass, and during the cutting process, the glass plate may be blown up or the glass substrate may be warped, so cooling is needed, and the cooling medium is cooling water.

[0004] For producing a glass substrate with a thickness of 1.1-10 mm, the thickness of the light edge on both sides reaches about 10-30 mm, when producing such a thick glass substrate, the thickness of the light edge is relatively thick, and if water spraying is used for cooling, the amount of water spraying cannot be too large, and the temperature difference cannot be too large, because if the amount of cooling water used is too large, the air pressure in the annealing lehr will increase due to the evaporation of water into a gaseous state, the hot air will be discharged to the outside, heat will be lost, and energy consumption will increase; in addition, the increase in the water content in the annealing lehr will also cause changes in the hydroxyl (-OH) on the surface of the glass substrate, affecting the performance of the glass; such a glass substrate is not suitable for a cooling device that simply uses cooling water for cooling.

[0037] Reference Figure 1 , Figure 2 , Figure 3 As shown in the drawings, the present embodiment discloses a glass light edge comprehensive cooling device for cooling the glass light edge of a glass substrate 8 located in an annealing furnace. The center thickness of the glass substrate 8 is 1.1-10 mm, and the thickness of the glass light edge on both sides reaches about 10-30 mm. When producing such a thicker glass substrate 8, cooling water and cooling gas are used as media for cooperative cooling.

[0038] In the water cooling aspect, the glass production annealing furnace side wall 9 is bolted to the mounting frame 1, the mounting frame 1 is rotatably connected to the support frame 2, the support frame 2 is sleeved on the outer periphery of the water spraying pipeline 4, and is slidably connected with the water spraying pipeline 4, that is, the water spraying pipeline 4 slides in the support frame 2, so as to change the relative position of the water spraying pipeline 4 and the support frame 2.

[0039] The water inlet pipe 6 penetrates the annealing furnace along the thickness direction of the annealing furnace side wall 9, one end outside the annealing furnace is connected with a water source, and the other end inside the annealing furnace is rotatably connected with the water spraying pipeline 4 and communicates with each other. Water flows to the water spraying pipeline 4 through the water inlet pipe 6. Specifically, the water spraying pipeline 4 is connected with the water inlet pipe 6 through a universal joint (not shown in the figure), or the water spraying pipeline 4 and the water inlet pipe 6 are connected through a hose 6. The water inlet pipe 6 can move along the thickness direction of the annealing furnace side wall 9. When the water inlet pipe 6 moves along the thickness direction of the annealing furnace side wall 9, it drives the water spraying pipeline 4 to slide in the support frame 2. However, the support frame 2 limits the water spraying pipeline 3, so that the angle between the water spraying pipeline 4 and the water inlet pipe 6 changes. When the angle of the water spraying pipeline 4 changes, the support frame 2 rotates relative to the mounting frame 1 to adapt to the change of the angle of the water spraying pipeline 4. When the angle of the water spraying pipeline 4 changes, the projection length of the water spraying pipeline 4 along the width direction of the glass substrate 8 changes, that is, the width of the light edge covered by the water spraying pipeline 4 changes, so that the water spraying pipeline 4 sprays different water areas to meet the cooling needs of light edges of different widths.

[0040] In the gas cooling aspect, the glass production annealing furnace side wall 9 is bolted to the second mounting frame 11, the second mounting frame 11 is rotatably connected to the second support frame 14, the second support frame 14 is sleeved on the outer periphery of the gas spraying pipeline 12, and is slidably connected with the gas spraying pipeline 12, that is, the gas spraying pipeline 12 slides in the second support frame 14, so as to change the relative position of the gas spraying pipeline 12 and the second support frame 14.

[0041] The air inlet pipe 10 penetrates the annealing furnace along the thickness direction of the annealing furnace side wall 9, is connected with a water source at one end outside the annealing furnace, and is rotatably connected with the air injection pipe 12 at one end inside the annealing furnace and is in communication with each other. The air flows to the air injection pipe 12 through the air inlet pipe 10. Specifically, the air injection pipe 12 is connected with the air inlet pipe 10 through a universal joint (not shown in the figure), or the air injection pipe 12 and the air inlet pipe 10 are connected through a second hose 13. The air inlet pipe 10 is movable along the thickness direction of the annealing furnace side wall. When the air inlet pipe 10 moves along the thickness direction of the annealing furnace side wall, the air injection pipe 12 slides in the second support frame 14. However, the second support frame 14 limits the air injection pipe 12, so that the angle of the air injection pipe 12 with the air inlet pipe 10 changes. When the angle of the air injection pipe 12 changes, the second support frame 14 rotates relative to the second mounting frame 11, so as to adapt to the angle change of the air injection pipe 12. When the angle of the air injection pipe 12 changes, the projection length of the air injection pipe 12 along the width direction of the glass substrate 8 changes, that is, the width of the light edge covered by the air injection pipe 12 changes, so that the air injection pipe 12 sprays different air injection areas to meet the cooling needs of light edges of different widths.

[0042] It should be noted that, in the direction perpendicular to the glass substrate, the position of the water injection pipe 4 is closer to the glass substrate than the position of the air injection pipe 12, and the air injection pipe 12 is closer to the center of the glass substrate 8 than the water injection pipe 4, which is more conducive to the cooling of the glass light edge.

[0043] The embodiment sprays air through the air injection pipe 12 to reduce the water injection amount during water cooling, so as to avoid that too large water injection amount causes too large temperature difference and glass explosion. The angle of the water injection pipe 4 and the air injection pipe 12 can be adjusted to adjust the cooling area to meet the cooling needs of light edges of different widths, improve the consistency of the annealing internal stress of the glass substrate 8, and improve the production efficiency and quality of products.

[0044] Further, the glass light edge cooling device further comprises a first locking bolt 15 and a second locking bolt 16. The first support frame 2 is provided with a threaded hole matched with the first locking bolt 15, and the first locking bolt 15 can abut on the outer periphery of the water injection pipe 4 through the threaded hole. The second support frame 14 is provided with a threaded hole matched with the second locking bolt 16, and the second locking bolt 16 can abut on the outer periphery of the air injection pipe 12 through the threaded hole. When the angle adjustment of the water injection pipe 4 and the air injection pipe 12 is completed, the first locking bolt 15 can abut on the outer periphery of the water injection pipe 4, and the second locking bolt 16 can abut on the outer periphery of the air injection pipe 12, so as to avoid that the water injection pipe 4 and the air injection pipe 12 slide due to water injection pressure and air injection pressure during water injection and air injection, the water injection angle and the air injection angle are changed, and the cooling stability is improved.

[0045] Furthermore, a first locking nut 5 is fitted onto the outer circumferential surface of the water inlet pipe 6 on the side outside the annealing furnace. After the angle adjustment is completed, the water inlet pipe 6 can be locked by the first locking nut 5, thereby restricting the movement of the water inlet pipe 6, further stabilizing the water spray angle, and improving the water spray stability during the water spraying process. A second locking nut 17 is fitted onto the outer circumferential surface of the air inlet pipe 10 on the side outside the annealing furnace. After the angle adjustment is completed, the air inlet pipe 10 can be locked by the second locking nut 17, thereby restricting the movement of the air inlet pipe 6, further stabilizing the air jet angle, and improving the air jet stability during the air jetting process.

[0046] Furthermore, the water spray pipe 4 has a plurality of water spray holes 7 on the side facing the glass substrate 8. The water spray pipe 4 can be located above or below the glass substrate 8, preferably above. The air jet pipe 12 has a plurality of air jet holes 18 on the side facing the glass substrate 8. The air jet pipe 12 can be located above or below the glass substrate 8, preferably above.

[0047] This utility model also discloses a glass production system, which includes a glass edge cooling device.

[0048] This utility model has a simple structure and low modification cost to the annealing furnace. It only requires opening threaded holes or through holes on the annealing furnace, fixing the first mounting bracket 1 and the second mounting bracket 11 to the inside with bolts, and connecting cooling water pipes and cooling air pipes to the outside.

[0049] This invention addresses the production of relatively thick glass substrates 8, with thicker polished edges, reaching approximately 10-30 mm on both sides. When using water spray cooling, the water volume cannot be too large, and the temperature difference cannot be too significant. If water is used for annealing, excessive water consumption will cause the water to evaporate into a gaseous state, leading to increased air pressure in the annealing furnace, heat loss due to hot air exhaust, and increased energy consumption. Furthermore, increased moisture content in the annealing furnace will cause changes in the hydroxyl groups (-OH) on the surface of the glass substrate 8, affecting the glass's performance.

[0050] To comprehensively reduce the temperature of the polished edge, a jet cooling device is configured to provide overall cooling. Furthermore, this invention allows for adjustment of the width of the water jet pipes to meet the cooling needs of different widths of polished edges for various products, improving the consistency of internal stress during annealing of the glass substrate 8, and enhancing product production efficiency and quality.
