FIG. 1 shows a schematic view of an exemplary glass product manufacturing apparatus 101 according to one embodiment.

Referring to fig. 1, the glass product manufacturing apparatus 101 may include a melting vessel 105, the melting vessel 105 configured to receive batch material 107 from a storage tank 109. The batch 107 may be introduced using a batch delivery device 111 powered by a motor 113. The optional controller 115 may be configured to actuate the motor 113 to introduce a desired amount of batch material 107 into the melting vessel 105, as indicated by arrow 117. The glass level probe 119 can be used to measure the level of glass melt 121 within the riser 123 and transmit the measured information to the controller 115 via the communication line 125.

The glass product manufacturing apparatus 101 can also include a fining vessel 127, such as a finer tube, located downstream from the melting vessel 105 and connected to the melting vessel 105 by a first connecting tube 129. A mixing vessel 131 (e.g., a stir chamber) may also be located downstream of the fining vessel 127, and a delivery vessel 133 (e.g., a bowl) may be located downstream of the stir vessel 131. As shown, a second connecting tube 135 may connect the fining vessel 127 to the stirring vessel 131, and a third connecting tube 137 may connect the stirring vessel 131 to the delivery vessel 133. As further shown, an outlet conduit 139 can be positioned to deliver the glass melt 121 from the delivery vessel 133 to an inlet 141 of a forming vessel 144. As shown, the melting vessel 105, fining vessel 127, mixing vessel 131, delivery vessel 133, and forming vessel 144 are examples of glass melting stations that may be positioned in series along the glass product manufacturing apparatus 101.

The melting vessel 105 is typically made of a refractory material, such as refractory (e.g., ceramic) bricks. The glass product manufacturing apparatus 101 can further include components that are typically made from platinum or platinum-containing metals, such as platinum-rhodium, platinum-iridium, and combinations thereof, but can also include refractory metals such as molybdenum, palladium, rhenium, tantalum, titanium, tungsten, ruthenium, osmium, zirconium, alloys thereof, and/or zirconium dioxide. The platinum-containing component can comprise one or more of first connection tube 129, fining vessel 127 (e.g., a finer tube), second connection tube 135, standpipe 123, mixing vessel 131 (e.g., a stir chamber), third connection tube 137, delivery vessel 133 (e.g., a bowl), outlet conduit 139, and inlet 141. The forming vessel 144 is also made of a refractory material and is designed to form the glass ribbon 103.

FIG. 2 is an exploded perspective view of a cooling module 110 and a melting vessel 105 according to one embodiment.

Referring to fig. 2, the melting vessel 105 may include a gas heating zone 105g and an electric heating zone 105 e. The gas heating zone 105g is generally located above the electric heating zone 105 e.

The gas heating zone 105g can supply energy to the melting vessel 105 by using a burner 105ga using gas as fuel. The electric heating zone 105e may supply energy into the melting vessel 105 by using the electrode 105 ea.

The electrode 105ea may be immersed in the glass melt in the melting vessel 105. In addition, the level of glass melt in the melting vessel 105 may be located between the level of the burner 105ga and the electrode 105 ea. That is, the burner 105ga may be located at a position higher than the highest level of the glass melt, and the electrode 105ea may be located at a position lower than the highest level of the glass melt. In some embodiments, the gas heating zone 105g may be located above the highest level of the glass melt and the electric heating zone 105e may be located below the highest level of the glass melt.

The electrode 105ea and the burner 105ga may be disposed on opposite sidewalls 105sw of the melting vessel 105 that face each other.

Furthermore, the cooling module 110 may be disposed on a wall of the melting vessel, such as a back wall 105bw of the melting vessel 105. One or more feed openings 105fh for supplying raw materials of the glass melt may be formed in the rear wall 105bw of the melting vessel 105. The glass melt produced in the melting vessel 105 may be supplied to the process of making the glass product through a front wall 105fw opposite a rear wall 105 bw.

The cooling module 110 may be disposed to at least partially overlap the electrical heating zone 105e adjacent thereto. In some embodiments, at least a portion of the cooling module 110 may be disposed to overlap at least a portion of the electrical heating zone 105 e. In some embodiments, the cooling module 110 may be disposed to completely overlap the electric heating zone 105 e. In some embodiments, the cooling module 110 may partially overlap the electrical heating zone 105e and partially overlap the gas heating zone 105 g. Here, "overlapping" with the electric heating zone 105e may mean that the periphery of the cooling module 110 overlaps with the electric heating zone 105e when the periphery of the cooling module 110 protrudes onto the outer surface of the melting vessel 105.

A support grid 112 may be disposed between the cooling module 110 and the rear wall 105 bw. The support grid 112 may support the rear wall 105 bw. In more detail, the molten glass 121 within the melting vessel 105 may exert a force that is urged in an outward direction toward the side walls of the melting vessel 105. Accordingly, a support grid 112 may be provided on the side walls of the melting vessel 105 for counteracting the force of the molten glass 121. A support grid 112 may be provided on each sidewall of the melting vessel 105.

The support grid 112 provides a plurality of openings or holes through which radiant energy emitted from the back wall 105bw will pass. If the support grid 112 is connected to the support frame 130 to support the sidewalls of the melting vessel 105, the shape of the support grid 112 will not be limited.

The cooling modules 110 disposed on the support grid 112 may be configured to transfer heat from the melting vessel 105 by conduction, convection, and/or radiation, as will be described in detail below.

The cooling module 110 may exchange heat using a heat transfer medium fluid. The heat transfer medium fluid may be, for example, water, oil, inert gas, etc., but is not limited thereto. In some embodiments, the heat transfer medium fluid may be water. The temperature of the heat transfer medium fluid rises during passage through the cooling module 110 because the heat transfer medium fluid absorbs heat from the melting vessel 105.

In detail, the difference between the temperature at the first inlet 110_ in and the temperature between the first outlet 110_ out, for example, about 7 to about 15, the heat transfer medium fluid is introduced into the cooling module 110 through the first inlet 110_ in, and the heat transfer medium fluid is discharged from the cooling module 110 through the first outlet 110_ out. For example, the temperature of the heat transfer medium fluid introduced through the first inlet 110_ in may be about 65 to about 75. In addition, the temperature of the heat transfer medium fluid discharged through the first outlet 110_ out may be, for example, about 75 to about 85.

The cooling module 110 may be disposed only on the rear wall 105bw of the melting vessel 105 and may not be disposed on the front wall 105fw of the melting vessel 105. Further, the cooling modules 110 may not be disposed on the two opposite sidewalls 105sw of the melting vessel 105.

Fig. 3 is a perspective view illustrating a relationship between the support frame 130, the cooling module 110, and the support grid 112 according to an embodiment.

Referring to fig. 3, the support grill 112 may support the rear wall 105bw (see fig. 2) together with the support frame 130.

Support frame 130 may include a plurality of beam structures 130V1, 130V2, 130V3, 130V4, 130H1, and 130H2, and a plurality of support structures 132 a-132 d extending from beam structures 130V1, 130V2, 130V3, 130V4, 130H1, and 130H 2. A plurality of support structures 132 a-132 d may extend in a lateral direction from beam structures 130V1, 130V2, 130V3, 130V4, 130H1, and 130H 2. In some embodiments, a plurality of support structures 132 a-132 d may extend horizontally from beam structures 130V1, 130V2, 130V3, 130V4, 130H1, and 130H 2.

In some embodiments, the beam structures 130V1, 130V2, 130V3, 130V4, 130H1, and 130H2 may comprise a plurality of horizontal beam structures 130H1 and 130H 2. In some embodiments, the beam structures 130V1, 130V2, 130V3, 130V4, 130H1, and 130H2 may comprise a plurality of vertical beam structures 130V1 to 130V 4. In some embodiments, the beam structures 130V1, 130V2, 130V3, 130V4, 130H1, and 130H2 may be directly or indirectly connected to each other.

In more detail, the beam structures 130V1, 130V2, 130V3, 130V4, 130H1, and 130H2 may include a first vertical beam structure 130V1, a second vertical beam structure 130V2, a third vertical beam structure 130V3, and a fourth vertical beam structure 130V 4. Also, the beam structures 130V1, 130V2, 130V3, 130V4, 130H1, and 130H2 may include a first horizontal beam structure 130H1 and a second horizontal beam structure 130H 2. The first horizontal beam structure 130H1 and the second horizontal beam structure 130H2 may extend between the third vertical beam structure 130V3 and the fourth vertical beam structure 130V4, and may be connected to the third vertical beam structure 130V3 and the fourth vertical beam structure 130V 4.

At least one of the support structures 132 a-132 d (e.g., first-fourth support structures 132 a-132 d) is removably attachable to the support grid 112. This may be achieved when at least one of the support structures 132 a-132 d is detachable from the first and second vertical beam structures 130V1, 130V 2. In some embodiments, each of the support structures 132 a-132 d may be independently and removably attached to the support grid 112.

In fig. 3, it is illustrated that the first and second support structures 132a and 132b are coupled to the first vertical beam structure 130V1, and the third and fourth support structures 132d and 132d are coupled to the second vertical beam structure 130V2, but the embodiment is not limited thereto. In some embodiments, the first support structure 132a and the second support structure 132b may be disposed in a vertical direction relative to each other. In some embodiments, the third and fourth support structures 132c, 132d may be arranged in a vertical direction relative to each other.

As shown in fig. 3, the support structures 132 a-132 d may support the support grid 112 and may limit movement of the support grid 112 such that the back wall 105bw is not moved by the force of the molten glass applied to the back wall 105 bw.

The cooling module 110 is removably secured to a support grid 112. For example, the cooling module 110 may be removably secured to the support grid 112 by a securing member 116. Since the force of the molten glass is not applied to the cooling module 110 or is not offset by the cooling module 110, the cooling module 110 may be loosely attached to the support grid 112. In some embodiments, the securing members 116 may have a securing connection force that allows the cooling module 110 not to separate or fall off the support grid 112.

For example, the fixing member 116 may be a jig, but the embodiment is not limited thereto.

Fig. 4A and 4B illustrate perspective views of a method of installing the cooling module 110 according to an embodiment.

Referring to fig. 4A, the illustration of fig. 4A is the same as the illustration of fig. 3, except that the cooling module 110 is omitted. Therefore, the repetitive description is omitted. However, the melting vessel 105 on which the cooling module 110 is mounted may be operated.

Referring to fig. 4B, the second support structure 132B may be separated from the support grid 112 while maintaining a fixed state of each of the first, third, and fourth support structures 132a, 132c, and 132 d. In other words, the second support structure 132b may be separate from the first vertical beam structure 130V 1.

Subsequently, the cooling module 110 may be inserted into the space between the support grid 112 and the first beam structure 130V1 through a space (the space between the support grid 112 and the first beam structure 130V1 in fig. 4B, which is penetrated by the second support structure 132B for fastening), which is fixed by the separation of the second support structure 132B.

Subsequently, the cooling module 110 may be secured to the support grid 112. As described above, the cooling module 110 may be fixed to the support grid 112 by the fixing member 116, but the embodiment is not limited thereto.

Subsequently, the separate second support structure 132b may be fastened again to the first vertical beam structure 130V 1.

While the above process is being performed, the melting vessel 105 is still in operation.

Fig. 5 is a front view illustrating a shape of the cooling module 110 installed in operation according to an embodiment.

Referring to fig. 5, the cooling module 110 may include a recess portion 110R disposed at a position corresponding to at least one of the first, third, and fourth support structures 132a, 132c, and 132 d. Due to the provision of the recess 110R, the main body portion of the cooling module 110 may extend up to the vertical direction or the horizontal direction in each of the support structures 132a to 132d, or to a position spaced apart from each of the support structures 132a to 132 d. Thus, the cooling module 110 may increase an area that may overlap the back wall 105 bw.

In some embodiments, a region of the back wall 105bw that overlaps the cooling module 110 may be about 40% to about 90% of the total area of the back wall 105 bw. For example, when the overlapping area is less than about 40% of the total area of the rear wall 105bw, the effect of cooling the rear wall 105bw of the melting vessel 105 may be insufficient. On the other hand, when the overlapping area is greater than about 90% of the total area of the rear wall 105bw, the effect of cooling the rear wall 105bw may be too excessive, and thus may be economically disadvantageous.

The primary heat transfer mechanism used to cool the back wall 105bw may be radiant heat, where the radiant heat passes through the support grid 112 and is transferred to the cooling modules 110. In some embodiments, the cooling module 110 may substantially contact the support grid 112, and thus, heat transfer by convection may not be very active. In some embodiments, the area of the support grid 112 facing the cooling module 110 may be less large due to the plurality of holes provided in the support grid 112. Thus, heat transfer by convection between the support grid 112 and the cooling module 110 may not be very active.

To effectively reduce glass melting and defects, it may be useful to selectively cool one or more walls (e.g., the back wall) of the melting vessel in order to more accurately control the temperature of the molten glass.

By using the glass product manufacturing apparatus and the method of manufacturing a glass product according to the embodiment, the cooling module 110 can be installed in the melting vessel 105 of the unit that is in operation without stopping the glass melting process. In particular, according to the glass product manufacturing apparatus and the method of manufacturing a glass product of the embodiment, the time taken to install the cooling module 110 is short, and any disturbance to the stability of the glass melting process is short.

By using the glass product manufacturing apparatus and the method of manufacturing a glass product according to the embodiment, energy efficiency can be maintained even when operating, and a defect rate can be reduced.

While the present disclosure has been particularly disclosed and described with reference to embodiments thereof, it will be understood that various changes in form and details may be made therein without departing from the spirit and scope of the appended claims.
