[0003] The present disclosure relates generally to glass melting systems and, more particularly, to apparatus and methods for reducing defects in glass melting vessels. Background Art

[0004] In the production process of glass products (such as glass sheets for display applications, display applications include televisions and handheld devices, such as phones and tablets), molten glass is transported by a glass melting system. The glass melting system generally includes a container or pipeline containing a noble metal or a noble metal alloy, wherein the molten glass is transported by the container or pipeline, and is in physical contact with the noble metal or the noble metal alloy. This contact between the molten glass and the noble metal or the noble metal alloy can lead to a chemical reaction, such as a redox reaction, in which the noble metal or noble metal oxide is transported into the molten glass or on the surface of the molten glass. The presence of such noble metals or noble metal oxides in the molten glass or on the surface of the molten glass can cause undesirable defects in the glass products. In addition, such reactions may cause corrosion of the container or pipeline of the glass melting system, thereby causing the need to repair or replace such components, and causing undesirable process downtime. Therefore, it is desirable to mitigate or suppress these effects. Summary of the invention

[0020] As used herein, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a" component includes aspects having two or more such components unless the context clearly dictates otherwise.

[0021] As used herein, the term "molten glass" refers to a glass composition at or above its liquidus temperature (above which no crystalline phase can coexist in equilibrium with the glass).

[0022] As used herein, the term "free surface of the molten glass" refers to the area of ​​the molten glass in contact with the atmosphere above the molten glass.

[0023] As used herein, the term "pipe" refers to a pipe or vessel of a glassmaking apparatus configured to flow molten glass through. Non-limiting exemplary pipes include mixing vessel 36, fining vessel 34, delivery vessel 40, and connecting pipes.

[0024] The term “connecting pipe” used herein refers to a pipe used to connect components of a glass manufacturing device and configured to allow molten glass to flow through. Non-limiting exemplary connecting pipes disclosed herein include a first connecting pipe 32 , a second connecting pipe 38 , and a third connecting pipe 46 .

[0025] Figure 1 An exemplary glass manufacturing apparatus 10 is shown. In some examples, the glass manufacturing apparatus 10 may include a glass melting furnace 12, which may include a melting vessel 14. In addition to the melting vessel 14, the glass melting furnace 12 also includes one or more additional components, such as a heating element (as will be described in more detail herein), which heats the raw materials and converts the raw materials into molten glass. In a further example, the glass melting furnace 12 may include a thermal management device (e.g., an insulating component) that reduces heat loss near the melting vessel. In a further example, the glass melting furnace 12 may include electronic equipment and / or electromechanical equipment that facilitates melting the raw materials into a glass melt. In addition, the glass melting furnace 12 may include a support structure (e.g., a support chassis, a support member, etc.) or other components.

[0026] Glass melting vessel 14 is generally made of refractory material, such as refractory ceramic material, for example, refractory ceramic material including alumina or zirconia. In some examples, glass melting vessel 14 can be made of refractory ceramic bricks. Specific embodiments of glass melting vessel 14 will be described in more detail below.

[0027] In some examples, the glass melting furnace can be incorporated as a component of a glass manufacturing apparatus for manufacturing glass substrates, such as continuous lengths of glass ribbon. In some examples, the glass melting furnace of the present disclosure can be incorporated as a component of a glass manufacturing apparatus, including a slot draw apparatus, a float bath apparatus, a down-draw apparatus (such as a fusion process), an up-draw apparatus, a press apparatus, a tube-draw apparatus, or any other glass manufacturing apparatus that can benefit from aspects disclosed herein. For example, Figure 1 A glass melting furnace 12 is schematically shown as a component of the fusion down-draw glass manufacturing apparatus 10 for fusion drawing a glass ribbon for subsequent processing into individual glass sheets.

[0028] The glassmaking apparatus 10, such as the fusion downdraw apparatus 10, may optionally include an upstream glassmaking apparatus 16 located upstream relative to the glass melting vessel 14. In some examples, a portion or all of the upstream glassmaking apparatus 16 may be incorporated as part of the glass melting furnace 12.

[0029] As shown in the illustrated example, the upstream glass manufacturing device 16 may include a storage bin 18, a raw material delivery device 20, and a motor 22 connected to the raw material delivery device. The storage bin 18 may be configured to store a certain amount of raw batch material 24, which may be fed into the melting vessel 14 of the glass melting furnace 12, as shown by arrow 26. The raw batch material 24 generally contains one or more glass-forming metal oxides and one or more modifiers. In some examples, the raw material delivery device 20 may be powered by the motor 22, so that the raw material delivery device 20 delivers a predetermined amount of the raw batch material 24 from the storage bin 18 to the melting vessel 14. In a further example, the motor 22 may power the raw material delivery device 20 to introduce the raw batch material 24 at a controlled rate based on the liquid level of the molten glass sensed downstream from the melting vessel 14. Subsequently, the raw batch material 24 in the melting vessel 14 may be heated to form a molten glass 28.

[0030] The glass manufacturing device 10 may also optionally include a downstream glass manufacturing device 30 located downstream relative to the glass melting furnace 12. In some examples, a portion of the downstream glass manufacturing device 30 may be incorporated as a portion of the glass melting furnace 12. In some cases, the first connecting pipe 32 discussed below or other portions of the downstream glass manufacturing device 30 may be incorporated as a portion of the glass melting furnace 12. The elements of the downstream glass manufacturing device (including the first connecting pipe 32) may be formed of precious metals. Suitable precious metals include platinum group metals or alloys thereof selected from a group of metals consisting of platinum, iridium, rhodium, osmium, ruthenium and palladium. For example, the downstream components of the glass manufacturing device may be formed of a platinum-rhodium alloy, the alloy including about 100% to about 60% by weight of platinum and about 0% to about 40% by weight of rhodium. However, other suitable metals may include molybdenum, rhenium, tantalum, titanium, tungsten and alloys thereof. Oxide dispersion strengthened (ODS) precious metal alloys are also possible.

[0031] The downstream glass manufacturing apparatus 30 may include a first conditioning (i.e., processing) vessel, such as a fining vessel 34, which is located downstream of the melting vessel 14 and is coupled to the melting vessel 14 via the first connecting conduit 32 mentioned above. In some examples, the molten glass 28 may be gravity fed from the melting vessel 14 to the fining vessel 34 via the first connecting conduit 32. For example, gravity may cause the molten glass 28 to flow from the melting vessel 14 to the fining vessel 34 through the internal passage of the first connecting conduit 32. However, it should be understood that other conditioning vessels may be located downstream of the melting vessel 14, such as between the melting vessel 14 and the fining vessel 34. In some embodiments, a conditioning vessel may be used between the melting vessel and the fining vessel, wherein the molten glass from the main melting vessel is further heated to continue the melting process, or is cooled to a temperature lower than the molten glass in the melting vessel before entering the fining vessel.

[0032] Bubbles can be removed from the molten glass 28 in the clarification container 34 by various techniques. For example, the original batch 24 may include a polyvalent compound (i.e., a clarifier), such as tin oxide, which undergoes a chemical reduction reaction and releases oxygen when heated. Other suitable clarifiers include, but are not limited to, arsenic, antimony, iron, and cerium. The clarification container 34 is heated to a temperature higher than the temperature of the melting container, thereby heating the molten glass and the clarifier. Oxygen bubbles generated by chemical reduction of the clarifier under temperature induction will rise in the molten glass in the clarification container, wherein the gas in the molten glass produced in the melting furnace can be diffused or coalesced into the oxygen bubbles generated by the clarifier. Then, the expanded bubbles can rise to the free surface of the molten glass in the clarification container and then be discharged from the clarification container. Oxygen bubbles can further induce mechanical mixing of the molten glass in the clarification container.

[0033] The downstream glass manufacturing device 30 may also include another conditioning vessel, such as a mixing vessel 36 for mixing the molten glass. The mixing vessel 36 may be located downstream of the clarification vessel 34. The mixing vessel 36 may be used to provide a uniform glass melt composition, thereby reducing chemical or thermal inhomogeneity lines that may otherwise exist in the clarified molten glass leaving the clarification vessel. As shown, the clarification vessel 34 may be coupled to the mixing vessel 36 via a second connecting pipe 38. In some examples, the molten glass 28 may be gravity fed from the clarification vessel 34 to the mixing vessel 36 via the second connecting pipe 38. For example, gravity may cause the molten glass 28 to flow from the clarification vessel 34 to the mixing vessel 36 through the internal passage of the second connecting pipe 38. It should be noted that although the mixing vessel 36 is illustrated as being located downstream of the clarification vessel 34, the mixing vessel 36 may also be located upstream of the clarification vessel 34. In some embodiments, the downstream glass manufacturing device 30 may include multiple mixing vessels, such as a mixing vessel upstream of the clarification vessel 34 and a mixing vessel downstream of the clarification vessel 34. These multiple mixing vessels may be of the same design or of different designs.

[0034] The downstream glass manufacturing device 30 may also include another regulating container, such as a conveying container 40 that may be located downstream of the mixing container 36. The conveying container 40 can regulate the molten glass 28 so that it is supplied to the downstream forming equipment. For example, the conveying container 40 can be used as an accumulator and / or a flow controller to adjust the flow of the molten glass 28 and / or provide a consistent flow of the molten glass 28 to the forming body 42 through the outlet pipe 44. As shown, the mixing container 36 can be coupled to the conveying container 40 through the third connecting pipe 46. In some examples, the molten glass 28 can be gravity-fed from the mixing container 36 to the conveying container 40 through the third connecting pipe 46. For example, gravity can drive the molten glass 28 to flow from the mixing container 36 to the conveying container 40 through the internal channel of the third connecting pipe 46.

[0035] The downstream glass manufacturing apparatus 30 may also include a forming apparatus 48, which includes the above-mentioned forming body 42 and an inlet pipe 50. The outlet pipe 44 may be positioned to deliver the molten glass 28 from the delivery container 40 to the inlet pipe 50 of the forming apparatus 48. For example, the outlet pipe 44 may be nested within and spaced apart from the inner surface of the inlet pipe 50, thereby providing a free surface of molten glass between the outer surface of the outlet pipe 44 and the inner surface of the inlet pipe 50. The forming body 42 in the fusion down-draw glass manufacturing apparatus may include a trough 52 located on the upper surface of the forming body and a converging forming surface 54 converging in the drawing direction along the bottom edge 56 of the forming body. The molten glass delivered to the forming body trough via the delivery container 40, the outlet pipe 44 and the inlet pipe 50 overflows the sidewalls of the trough and descends along the converging forming surface 54 as a separate stream of molten glass. The individual molten glass streams merge below and along the bottom edge 56 to produce a single glass ribbon 58, which is drawn from the bottom edge 56 along a drawing or flow direction 60 by applying tension to the glass ribbon (such as by gravity, edge rollers 72, and pulling rollers 82) to control the size of the glass ribbon as the glass cools and the viscosity of the glass increases. As a result, the glass ribbon 58 undergoes a viscoelastic transition and acquires mechanical properties that impart stable dimensional characteristics to the glass ribbon 58. In some embodiments, the glass ribbon 58 can be separated into individual glass sheets 62 by the glass separation device 100 in the elastic region of the glass ribbon. The robot 64 can then transfer the individual glass sheets 62 to a conveyor system using a gripping tool 65, whereupon the individual glass sheets can be further processed.

[0036] Figure 2 A schematic side cross-sectional view of a portion of an exemplary mixing vessel 36 according to an embodiment disclosed herein is shown. The mixing vessel 36 is configured to process molten glass 28 and includes a wall 140 circumferentially around an inner chamber 144 that accommodates molten glass 28. The wall 140 also circumferentially surrounds a rotatable central shaft 132, from which a stirring blade 142 extends. In addition, the mixing vessel 36 includes a removable lid 160, which is configured to cover the inner chamber 144 and circumferentially around the rotatable central shaft 132. The removable lid 160 is configured to allow the rotatable central shaft 132 to extend therethrough and can, for example, include two approximately semicircular segments that extend around the rotatable central shaft 132 in a clamshell manner. The removable lid 160 can be fixed to the remainder of the mixing vessel by bolts 162.

[0037] The mixing container 36 also includes a condensate trap 150 located between the removable lid 160 and the wall 140. The condensate trap 150 has a generally circular cross-section, which may include two semicircular segments joined or welded together. The condensate trap 150 includes a vertically extending surface 152 and a horizontally extending surface 154. Figure 3 Shows Figure 2 A schematic top cross-sectional view of an exemplary mixing container 36 is shown. Figure 3 As shown, the inner diameter VID of the vertically extending surface 152 of the condensate trap 150 is greater than the inner diameter HID of the horizontally extending surface 154. In addition, the outer diameter COD of the condensate trap 150 is greater than the outer diameter WOD of the wall 140. Figure 3 As further shown, the inner diameter HID of the horizontally extending surface 154 is equal to the inner diameter WID of the wall 154 .

[0038] exist Figure 2 and Figure 3 In the illustrated embodiment, the condensate trap 150 is permanently attached to the wall 140. For example, the condensate trap 150 can be welded to the wall 140 according to methods known to those of ordinary skill in the art. In such an embodiment, a removable cover 160 can be removably attached to the condensate trap 150 by bolts 162. In addition, a retaining ring 164 extends along the inner diameter of the horizontally extending surface 154, and a plurality of gussets 158 extend radially along the horizontally extending surface 154. The retaining ring 164 can help contain the condensate within the condensate trap 150, and the plurality of gussets 158 can help maintain the generally cylindrical shape of the wall 140 and the vertically extending surface 152 during operation.

[0039] Figure 4 and Figure 5 1 shows a schematic side cross-sectional view of a portion of another exemplary mixing container 36 according to embodiments disclosed herein. Figure 2 and Figure 3 As in the embodiment shown, mixing vessel 36 is configured to process molten glass 28 and comprises a wall 140 circumferentially around an inner chamber 144 that holds molten glass 28. Wall 140 also circumferentially around a rotatable central shaft 132, from which a stirring blade 142 extends. In addition, mixing vessel 36 comprises a removable cover 160, which is configured to cover inner chamber 144 and circumferentially around a rotatable central shaft 132. Removable cover 160 is configured to allow rotatable central shaft 132 to extend therethrough and can, for example, comprise two approximately semicircular segments, which extend around rotatable central shaft 132 in a clamshell manner. Removable cover 160 can be fixed to the remainder of mixing vessel by bolts 162.

[0040] The mixing container 36 also includes a condensate trap 150' located between the removable lid 160 and the wall 140. The condensate trap 150' includes a generally circular cross-section, which may include two semicircular segments joined or welded together. The condensate trap 150' includes a vertically extending surface 152', a horizontally extending surface 154', and a horizontally extending flange 156. In addition, a retaining ring 164 extends along the inner diameter of the horizontally extending surface 154'.

[0041] like Figure 4 and Figure 5 As shown, the condensation water trap 150' is removably inserted between the removable cover 160 and the wall 140. Specifically, as shown in FIG. Figure 4 As shown, the condensate trap 150' can be moved in a vertical direction (as shown by arrow V) to the upper part of the wall until it is Figure 5 As shown, the horizontally extending flange 156 rests on the top of the wall 140. Figures 4 to 6 As shown, the outer diameter VOD of the vertically extending surface 152' is smaller than the inner diameter WID of the wall 140. In addition, the outer diameter COD of the condensate trap 150' is larger than the outer diameter WOD of the wall 140. Figure 6 As further shown, the inner diameter HID of the horizontally extending surface 154 is smaller than the inner diameter WID of the wall 154 .

[0042] Figure 7 1 shows a schematic side cross-sectional view of a portion of an exemplary condensate trap 150 and a retaining ring 164 according to embodiments disclosed herein. In certain exemplary embodiments, the vertically extending surfaces 152, 152' extend a vertical distance ( Figure 7 The horizontal distance (indicated by the double arrow H) of the horizontal extension surface 154 and 154' is large enough to allow the horizontal extension surface 154 and 154' to be immersed in the molten glass 28, and the horizontal extension surface 154 and 154' extends Figure 7 The retaining ring 164 may be large enough to allow condensate to settle on the surface between the vertically extending surfaces 152, 152' and the retaining ring 164. In certain exemplary embodiments, the retaining ring may extend a vertical distance ( Figure 7 1 ), the distance is in the range of about 0.5 inch to about 1 inch above the horizontally extending surfaces 154, 154'.

[0043] In certain exemplary embodiments, the condensate trap 150, 150' comprises the same material as the wall 140. In certain exemplary embodiments, the condensate trap 150, 150' comprises a metal selected from at least one of platinum, iridium, rhodium, osmium, ruthenium, and palladium, or an alloy thereof. In certain exemplary embodiments, the condensate trap 150, 150' comprises platinum, including at least one alloy comprising platinum, such as an alloy comprising platinum and rhodium, such as a platinum-rhodium alloy comprising about 70 to about 90 weight percent platinum and about 10 to 30 weight percent rhodium. However, other suitable metals may include molybdenum, palladium, rhenium, tantalum, titanium, tungsten, and alloys thereof.

[0044] The condensate traps 150, 150' inhibit the transport of precious metals or precious metal oxides into the molten glass 28. For example, when the mixing vessel 36 contains a platinum / rhodium alloy and contains an oxygen-rich atmosphere above the molten glass 28, the following redox reaction occurs:

[0045] Pt·Rh+O2→Pt·RhO2

[0046] Such a reaction may result in the presence of undesirable amounts of platinum and / or rhodium oxides from the atmosphere entering the molten glass 28. The reaction also allows the formation of noble metal gases which can now serve as a source of defect formation via the reverse reaction:

[0047] Pt·RhO2→O2+Pt·Rh

[0048] This reverse step may also involve other reactions, such as redox reactions of multivalent elements (SnO / SnO2, FeO / Fe2O3, etc.). The condensate traps 150, 150' may allow these defects to reside on the horizontally extending surfaces 154, 154' rather than within the body of the molten glass 28 contained within the mixing vessel 36. By depositing these defects on the condensate traps 150, 150' rather than on the body of the molten glass 28, glass products, such as glass sheets, may be produced with fewer undesirable defects present. Such glass products may be used, for example, in electronic devices, where the glass products have higher quality characteristics.

[0049] Although the above embodiments have been described with reference to a fusion down-draw process, it will be appreciated that these embodiments may also be applied to other glass forming processes, such as a float process, a slot draw process, an up-draw process, a tube draw process, and a press process.

[0050] It will be apparent to those skilled in the art that various modifications and changes may be made to the embodiments of the present disclosure without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure is intended to cover such modifications and changes as long as they fall within the scope of the appended claims and their equivalents.
