The glass production equipment is provided with a kiln, a forming device and a connecting pipeline, wherein the connecting pipeline is respectively communicated with a melting cavity of the kiln and a forming cavity of the forming device so as to guide high-temperature glass liquid in the melting cavity into the forming cavity, and the high-temperature glass liquid entering the forming cavity is formed into a glass plate or glass ingot after forming.

Such as: in the manufacturing process of glass products such as thin film transistors (TFT, thin Film Transistor), low temperature polysilicon (LTPS, low Temperature Poly-Silicon), organic Light-Emitting devices (OLED), pharmaceutical glass bottles, and the like, raw materials are melted first in a kiln, molten glass is fed into a forming device through a connecting pipeline to be manufactured into glass plates or glass ingots, and then processed to form thin film transistors, low temperature polysilicon, organic Light-Emitting devices, pharmaceutical glass bottles, and the like.

The bottom of the connecting pipeline is provided with an openable opening, when the forming device needs to be maintained or replaced, the input of raw materials for producing glass into the kiln is stopped, and then the opening at the bottom of the connecting pipeline is opened to enable glass liquid in the kiln and the connecting pipeline to flow out of the opening, so that the forming device is maintained or replaced when no high-temperature glass liquid enters the forming cavity.

However, with the gradual reduction of the high-temperature molten glass in the kiln and the connecting pipeline, the inner wall of the kiln made of refractory materials is exposed and then eroded and peeled off to form a stone phenomenon, and the inner wall of the connecting pipeline is exposed and then volatile matters are formed, so that when the production is restarted, the quality of the glass plate/glass ingot is low due to the fact that the stone and the volatile matters are mixed in the molten glass.

To this end, the present disclosure provides a glass production apparatus, as shown in fig. 1 to 4, comprising: the device comprises a melting device 1, a forming device 2 and a connecting pipeline 3, wherein the melting device 1 is provided with a melting cavity 11 and a first inlet and a first outlet 12 which are respectively communicated with the melting cavity 11, the forming device 2 is provided with a forming cavity 21 and a second inlet 22 and a second outlet which are respectively communicated with the forming cavity 21, two ends of the connecting pipeline 3 are respectively communicated with the melting cavity 11 and the forming cavity 21 through the first outlet 12 and the second inlet 22, a first section pipeline 31 is arranged at a position, close to the forming device 2, on the connecting pipeline 3, a temperature adjusting structure 4 is arranged on the first section pipeline 31 or on the periphery of the first section pipeline 31, a first temperature detecting structure is arranged on the first section pipeline 31, the temperature adjusting structure 4 can adjust the temperature of the first section pipeline 31, and the first temperature detecting structure can acquire the temperature of the first section pipeline 31.

Specifically, the melting device 1 may be a kiln or other devices. Here, since the raw material for glass production therein is melted by combustion in the melting chamber 11 of the melting apparatus 1, the melting apparatus 1 is made of at least a refractory material.

The temperature of the glass liquid entering the forming cavity 21 of the forming device 2 is high, so that the part of the forming device 2 contacting the glass liquid is at least made of high-temperature resistant materials, thereby reducing the probability of occurrence of stones and node defects at the part contacting the glass liquid.

The two ends of the connecting pipeline 3 are respectively communicated with the melting cavity 11 and the forming cavity 21 through the first outlet 12 and the second inlet 22, where one end of the connecting pipeline 3 may be directly connected with the first outlet 12, may be connected through a connecting piece such as a connecting pipe, and may also be opposite to the first outlet 12, for example: referring to fig. 1, one end of the connecting pipe 3 is directly connected to the first outlet 12 by welding, for example: the first outlet 12 is positioned at the bottom of the melting device 1, and one end of the connecting pipeline 3 is arranged below the first outlet 12 and opposite to the first outlet 12; the other end of the connecting pipeline 3 may be directly connected to the second inlet 22, or may be connected to a connecting member such as a connecting tube, or may be opposite to the second inlet 22, for example: referring to fig. 1, the other end of the connecting pipe 3 is directly connected with the second inlet 22 by welding. The temperature of the glass liquid entering the connecting pipeline 3 is high, so that the part of the connecting pipeline 3 contacting the glass liquid is at least made of a high-temperature-resistant material, and the probability of occurrence of stone and node defects of the part contacting the glass liquid is reduced. The outside of the connecting pipe 3 may be provided with a heat insulating material 311 as shown in fig. 4 to ensure that the temperature of the glass liquid entering the forming device 2 meets the requirement before forming, so as to avoid that the glass liquid temperature is low and the forming process such as stretching cannot be performed, and alumina refractory mortar and refractory material may be sequentially arranged between the connecting pipe 3 and the heat insulating material 311 to prolong the service life of the connecting pipe 3.

The temperature adjusting structure 4 may be disposed on the first section of pipeline 31, may be disposed on the connecting pipeline 3 adjacent to the first section of pipeline 31, or may be disposed beside the first section of pipeline 31. The first temperature detecting structure may be a thermocouple or other temperature detecting structures.

The application method comprises the following steps: raw materials for manufacturing glass enter the melting cavity 11 from the first inlet, are melted Cheng Gaowen by high temperature in the melting cavity 11, and enter the forming cavity 21 of the forming device 2 through the first outlet 12, the connecting pipeline 3 and the second inlet 22 to form a glass plate or glass ingot after the forming process is completed in the forming cavity 21 and are output through the second outlet. When the forming device 2 needs to be maintained or replaced, the temperature of the first section of pipeline 31 can be reduced through the temperature adjusting structure 4, and when the temperature in the first section of pipeline 31 is detected to be reduced to the freezing point temperature through the first temperature detecting structure, the forming device 2 can be maintained or replaced at the moment. After maintenance or replacement, the temperature of the first section of pipeline 31 is increased through the temperature adjusting structure 4, so that the frozen glass liquid in the first section of pipeline 31 is melted and flows into the forming cavity 21 of the forming device 2, and then the production of glass can be restored.

In this embodiment, by setting the temperature adjusting structure 4 and the first temperature detecting structure, the forming device 2 can be maintained or replaced without evacuating the glass liquid in the melting device 1 and the connecting pipeline 3, so that the maintenance/replacement time can be reduced, the probability of forming stone defects due to erosion and peeling of the inner wall of the melting device 1 caused by liquid level reduction is reduced, and the probability of volatile defects of the connecting pipeline 3 caused by liquid level reduction is reduced, thereby improving the quality of the glass plate/glass ingot after production recovery. Moreover, when the connecting pipe 3 is made of platinum or a platinum alloy, the risk of collapse is liable to occur due to insufficient pressure in the connecting pipe 3 caused by the decrease in temperature in the connecting pipe 3 as the high-temperature molten glass in the melting device 1 and the connecting pipe 3 gradually decreases, and the present utility model can reduce the occurrence of such a situation, thereby enabling the service life of the connecting pipe 3 to be prolonged. In addition, since the step of discharging the high-temperature molten glass from the connecting pipe 3 is reduced, the time required for restarting the production after the maintenance or the replacement of the molding apparatus 2 can be shortened.

In some embodiments, as shown in fig. 1, a second section of pipeline 32 and a third section of pipeline 33 connected to two ends of the first section of pipeline 31 on the connecting pipeline 3 respectively extend along a vertical direction, a first included angle is formed between the second section of pipeline 32 and the first section of pipeline 31, and a second included angle is formed between the third section of pipeline 33 and the first section of pipeline 31. In other words, the first-stage pipeline 31 is inclined to the vertical direction, so that the flow inertia of the glass liquid in the first-stage pipeline 31 can be buffered, that is, the flow rate of the glass liquid in the first-stage pipeline 31 can be slowed down, and therefore, the glass liquid in the first-stage pipeline 31 is easier to freeze after the temperature in the first-stage pipeline 31 is reduced by the temperature regulating structure 4.

In the specific implementation process, the first section of pipeline 31, the second section of pipeline 32 and the third section of pipeline 33 can be of an integrated structure, so that the number of structures of the connecting pipeline 3 can be reduced to improve the assembly efficiency of the connecting pipeline.

In some embodiments, referring to fig. 1, the tempering structure 4 comprises: the first electrode flange 41 and the second electrode flange 42, the first electrode flange 41 and the second electrode flange 42 are respectively arranged on the second section pipeline 32 and the third section pipeline 33, and the first electrode flange 41 and the second electrode flange 42 can be respectively connected with the first power supply equipment; the connection line 3 between the first electrode flange 41 and the second electrode flange 42 can be electrically conductive, so that the first electrode flange 41, the second electrode flange 42, the connection line 3 between the first electrode flange 41 and the second electrode flange 42, and the first power supply device form a current loop. Thus, when the first power supply device supplies power, the connecting pipeline 3 (comprising the first-section pipeline 31) between the first electrode flange 41 and the second electrode flange 42 passes through the current, and the generation of the current is accompanied by the generation of heat, so that the first-section pipeline 31 has a temperature, the glass liquid in the first-section pipeline 31 can be cooled when the temperature of the first-section pipeline 31 is lower than the temperature of the glass liquid in the first-section pipeline 31, and the glass liquid in the first-section pipeline 31 can be heated when the temperature of the first-section pipeline 31 is higher than the temperature of the glass liquid in the first-section pipeline 31.

Here, when the glass production apparatus is normally producing, the first power supply apparatus may supply power to the first electrode flange 41, the second electrode flange 42, and the connection pipe 3 between the first electrode flange 41 and the second electrode flange 42, and the temperature is provided to ensure that the temperature of the glass liquid to be introduced into the forming device 2 is kept within a predetermined range, so that it is possible to reduce the influence on the progress of the forming process such as drawing due to the temperature of the glass liquid introduced into the forming device 2 falling to the predetermined range.

In some embodiments, as shown with reference to FIG. 1, the first included angle ranges from 90 to 150; and/or the second included angle is in the range of 90 ° to 150 °. Here, the first-stage pipe 31 is inclined to the vertical direction, so that the flow inertia of the glass liquid in the first-stage pipe 31 can be buffered, i.e. the flow rate of the glass liquid in the first-stage pipe 31 can be slowed down, whereby the glass liquid in the first-stage pipe 31 is more easily frozen after the temperature in the first-stage pipe 31 is lowered by the temperature regulating structure 4.

Further, the first included angle ranges from 110 DEG to 120 DEG; and/or the second included angle is in the range of 110 ° -120 °. Here, the first-stage pipe 31 is inclined to the vertical direction, so that the flow inertia of the glass liquid in the first-stage pipe 31 can be buffered, i.e. the flow rate of the glass liquid in the first-stage pipe 31 can be slowed down, whereby the glass liquid in the first-stage pipe 31 is more easily frozen after the temperature in the first-stage pipe 31 is lowered by the temperature regulating structure 4.

In some embodiments, as shown in fig. 1, the second section of pipeline 32 is located at an end of the first section of pipeline 31 away from the forming device 2, and a first opening 34 is formed in a vertical direction from an end of the connecting pipeline 3 near the first outlet 12 to an upper end between the second section of pipeline 32. Here, the arrangement of the first opening 34 can communicate the inside and outside of the connecting pipeline 3, so that the gas in the glass liquid in the connecting pipeline 3 can be discharged through the first opening 34, thereby improving the quality of the formed glass plate/glass ingot, and increasing the gravity of the glass liquid entering the second-stage pipeline 32, so as to reduce the probability of blockage between the second-stage pipeline 32 and the forming device 2, and improve the smoothness of glass liquid flow.

In some embodiments, referring to fig. 1, the inner pipe wall of the connecting pipe 3 corresponding to the lower end of the first opening 34 is recessed downward to form a pressure chamber 35, and the bottom wall of the pressure chamber 35 is connected to the end of the second-stage pipe 32 remote from the first-stage pipe 31. Therefore, the gravity of the glass liquid entering the second-stage pipeline 32 can be further increased, so that the probability of blockage between the second-stage pipeline 32 and the forming device 2 is reduced, and the smoothness of the flow of the glass liquid is improved.

In some embodiments, referring to fig. 1, a second opening 36 is formed in the connecting pipe 3 from one end of the connecting pipe 3 near the first outlet 12 to an upper end between the first openings 34 in a vertical direction, and the stirring rod 5 extends into the connecting pipe 3 from the second opening 36 to stir the glass liquid in the connecting pipe 3. Stirring makes the glass liquid more uniform so as to improve the quality of the formed glass plate/glass ingot. Here, in order to increase stirring force and improve quality of the glass plate/ingot, stirring blade may be attached to stirring rod 5 as shown in fig. 1.

In some embodiments, as shown in fig. 1, the connecting line 3 is provided with a discharge outlet 37 which can be opened in correspondence of the lower end of the second opening 36; and/or the inner pipe wall of the connecting pipeline 3 corresponding to the lower end of the second opening 36 is recessed downwards to form a stirring cavity 38, and the stirring rod 5 extends into the stirring cavity 38 from the second opening 36 so as to be capable of stirring glass liquid in the stirring cavity 38.

Specifically, the above-described discharge outlet 37 enables the molten glass in the connecting pipe 3 to be discharged via the discharge outlet 37, such as: the molten glass remaining in the connecting line 3 when it is replaced can be discharged through the discharge outlet 37. The stirring chamber 38 is provided so that each part of the molten glass stays at the stirring position for a long time, thereby further improving the quality of the formed glass sheet/ingot.

In some embodiments, referring to fig. 1, the connecting line 3 is provided with a third opening 39 in a vertical direction from an end near the first outlet 12 to an upper end between the second openings 36. Thus, bubbles in the molten glass can be discharged through the third opening 39, and the quality of the formed glass sheet/ingot can be improved.

In some embodiments, referring to fig. 1, the connection pipeline 3 is a platinum pipeline or a platinum alloy pipeline, the connection pipeline 3 can be connected with a second power supply device or a heat dissipation device, and a plurality of second temperature detection structures are arranged on the connection pipeline 3 from one end close to the first outlet 12 to one end close to the second inlet 22.

Specifically, the connecting pipe 3 is a platinum pipe or a platinum alloy pipe, so that the connecting pipe 3 has conductive performance, and therefore, when the connecting pipe 3 is connected with the second power supply device, heat is generated due to the electrification, and the heat can enable the glass liquid in the connecting pipe 3 to be maintained within a certain range. The connecting pipeline 3 is a platinum pipeline or a platinum alloy pipeline, so that the connecting pipeline 3 has heat conducting performance, therefore, after the connecting pipeline 3 is connected with the heat dissipating device, heat provided by the heat dissipating device can be conducted away by the connecting pipeline 3, and the heat conducted away by the connecting pipeline 3 can enable glass liquid in the connecting pipeline 3 to be maintained in a certain range. Here, the purpose of the connection to the second power supply device or the heat sink is to ensure that the temperature of the molten glass in the connection pipe 3 is maintained within a certain range, so as to reduce the occurrence of a molding process such as drawing being impossible in the molding device 2 due to an excessively low temperature of the molten glass.

The second temperature detection structure can detect the temperature of the position where the second temperature detection structure is located, so that a worker can determine whether to continue heating the glass liquid in the connecting pipeline 3 according to the detected temperature, and if the temperature is not required to be continuously increased, the power supply of the second power supply equipment and the heating of the second heat dissipation device can be stopped. The second temperature detecting structure may be a thermocouple or other temperature detecting structure.

In addition, platinum and platinum alloys have good corrosion and high temperature resistance characteristics, so that the platinum and platinum alloys are suitable for manufacturing the connecting pipeline 3.

In the process of producing glass, S101: when the forming device 2 needs to be replaced, the current between the first electrode flange 41 and the second electrode flange 42 is gradually reduced (the current reducing rate is 10-200A/min, such as 100A/min), the temperature of the glass liquid flowing through the first section of pipeline 31 is obtained through a first temperature detection structure on the first section of pipeline 31, and the change of the liquid level in the glass production equipment is paid attention to at any time, so that the change of the liquid level is ensured to be within +/-3 mm by controlling the feeding speed.

S102: when the obtained temperature is below 800 ℃ and the molten glass is frozen inside the first-stage pipe 31, further reduction of the current to the first electrode flange 41 and the second electrode flange 42 is stopped, and the molten glass in the third-stage pipe 33 and the molten glass remaining in the forming device 2 are waited for to be completely discharged from the second outlet of the forming device 2. At this point, the feed to the first inlet was stopped to ensure that the level was varied to within + -3 mm.

In another glass production process, S201: when the forming device 2 needs to be replaced, the current between the first electrode flange 41 and the second electrode flange 42 is gradually reduced (the current reducing rate is 10-200A/min, such as 200A/min), the temperature of the glass liquid flowing through the first section of pipeline 31 is obtained through a first temperature detection structure on the first section of pipeline 31, and the change of the liquid level in the glass production equipment is paid attention to at any time, so that the change of the liquid level is ensured to be within +/-3 mm by controlling the feeding speed.

S202: when the obtained temperature is below 800 ℃ and the molten glass is frozen inside the first-stage pipe 31, further reduction of the current to the first electrode flange 41 and the second electrode flange 42 is stopped, and the molten glass in the third-stage pipe 33 and the molten glass remaining in the forming device 2 are waited for to be completely discharged from the second outlet of the forming device 2. At this point, the feed to the first inlet was stopped to ensure that the level was varied to within + -3 mm.

S203: the insulation 311 between the third section of tubing 33 and the forming device 2 is removed and the two are severed.

S204: the molding device 2 is replaced.

S205: the temperature of the exchanged molding device 2 is raised to 1100-1300 c (e.g., 1100 c).

S206: the third pipeline 33 is welded to the replaced molding device 2, and a heat insulating material 311 is added to the outside of the welding position.

S207: the current of the first electrode flange 41 and the second electrode flange 42 is gradually increased (for example, the current increasing speed is 10-200A/min, for example, 200A/min), the temperature of the glass liquid in the first section of pipeline 31 is obtained through the first temperature detecting structure, the glass liquid flows out into the forming device 2 after the temperature is increased, in the process, the glass liquid level is monitored to ensure that the liquid level changes within +/-3 mm, and raw materials are started to be added to the first inlet of the melting device 1 when the glass liquid level is lower than-3 mm.

S208: so far, the replacement of the molding device 2 and the restoration of the glass production after the replacement are completed.

Through experiments, the operation can be completed in 1.5 days from S201 to S208, but in the prior art, the glass liquid in the kiln and the connecting pipeline is discharged first, then the forming device 2 is replaced, and finally the production is restarted in 10-15 days.

In this embodiment, the raw materials form glass liquid in the melting chamber 11 of the melting device 1, and are clarified in the clarification section of the connecting pipeline 3, homogenized in the stirring section and output in the material conveying section, so that a glass plate or glass ingot is formed after the forming is completed in the forming chamber 21 of the forming device 2, and in this process, the occurrence probability of defects in the produced glass plate/glass ingot can be reduced through the clarification and homogenization processes. In addition, in the process of failure or replacement of the molding device 2, the glass liquid in the first section of pipeline 31 is frozen, so that the glass liquid in the melting chamber 11 of the melting device 1 and the connecting pipeline 3 does not need to be discharged, the probability of forming stone defects due to erosion and peeling of the inner wall of the melting device 1 due to liquid level reduction is reduced, and the probability of volatile defects of the connecting pipeline 3 due to liquid level reduction is reduced, thereby improving the quality of the glass plate/glass ingot after production recovery. Meanwhile, after the maintenance or replacement of the molding device 2 is completed, the work of glass production can be quickly entered, and thus the production efficiency can be improved.
