Description

Technical Field

[0001] The present disclosure relates to the technical field of glass production, and in particular to a slot down-draw glass production device and slot down-draw glass production equipment. Background Art

[0002] The slot-down draw method mainly introduces the molten glass liquid into a trough made of platinum-rhodium alloy, and flows out from the slit at the bottom of the trough, and uses its own gravity and downward pulling force to draw it into ultra-thin glass.

[0003] When producing plate glass using the slit down-draw method, molten glass enters the drawing groove from the material pipe and then flows out from the nozzle to form a glass plate below the slit. In the process of the molten glass filling the drawing groove, the molten glass will gradually squeeze out the air in the drawing groove. In the existing technology, an exhaust pipe is set to discharge the air in the drawing groove from the exhaust pipe to keep the air pressure in the drawing groove stable.

[0004] However, as the molten glass gradually fills the groove and the nozzle and material pipe of the groove are sealed, the narrow groove will also be divided, so that the air inside the groove is divided into two parts by the molten glass. These two parts of air can no longer flow freely, resulting in the exhaust pipe being able to discharge only part of the air, and the other part remaining in the groove will increase the pressure inside the groove under the squeezing of the molten glass, causing the groove to deform and damage. Summary of the Invention

[0005] A technical problem to be solved by the present disclosure is that the air in the drawing groove forms two air areas due to the obstruction and separation of the glass liquid. The existing exhaust pipe cannot exhaust the air in the drawing groove, resulting in an increase in pressure in the drawing groove, causing the drawing groove to deform and affecting the service life of the drawing groove.

[0006] To solve the above technical problems, the present disclosure provides a slot down-draw glass production device, comprising: a receiving portion, wherein the receiving portion has an accommodating space therein, the accommodating space having a first side surface and a second side surface disposed opposite to each other in a longitudinal direction, both the first side surface and the second side surface extending in a first horizontal direction;

[0007] a discharge portion, the discharge portion being in communication with the first side surface of the accommodating space and extending along a first direction;

[0008] a feed pipe, the feed pipe being in communication with the second side surface of the accommodating space; and

[0009] The voltage stabilizing part includes two exhaust structures, which are respectively connected to the second side of the accommodating space, and the connection points between the exhaust structure and the accommodating space are respectively located on both sides of the feed pipe along the first direction. The exhaust structure is used to adjust the pressure in the accommodating space so that the pressure in the accommodating space is stabilized at a preset value.

[0010] In some embodiments, the exhaust structure includes: a first air pipe and a pressure stabilizer;

[0011] One end of the first air pipe is communicated with the second side surface of the accommodating space, and the other end is communicated with the pressure stabilizer, and the pressure stabilizer is communicated with the external atmosphere.

[0012] In some embodiments, the exhaust structure further comprises:

[0013] The second air pipe has one end connected to the pressure stabilizer, and the other end connected to an external high-pressure air pipeline.

[0014] In some embodiments, the exhaust structure further comprises:

[0015] The third air pipe has one end connected to the pressure regulator, and the other end of the third air pipe is used to connect to the external atmosphere. The pressure regulator is connected to the external atmosphere through the third air pipe.

[0016] In some embodiments, the connection point between the feed pipe and the accommodating space is located in the middle of the second side surface along the extension direction of the accommodating space.

[0017] In some embodiments, the two exhaust structures are symmetrically arranged along the extension direction of the accommodating space with the feed pipe as the center.

[0018] In some embodiments, the voltage stabilizing unit further includes:

[0019] The heating element has a heating portion capable of generating heat, and the heating portion is arranged around the outer wall of the first air pipe.

[0020] In some embodiments, a cooling tube, a first end of the cooling tube is connected to the pressure stabilizer, and a second end of the cooling tube is used to communicate with an external cold air pipeline.

[0021] In some embodiments, the first end of the cooling pipe is connected to the second air pipe, and the cooling pipe is connected to the pressure regulator through the second air pipe.

[0022] A second aspect of the present application provides a slot down-draw glass production device, comprising: a production device body; and

[0023] The aforementioned slot down-draw glass production device.

[0024] Through the above technical solution, the present invention provides a slit down-draw glass production device, which can adjust the pressure in the accommodating space inside the accommodating part through the pressure stabilizing part, so that the pressure in the accommodating space is stabilized at a preset value, thereby avoiding the pressure in the accommodating space being too high or too low during the production and discharge process, causing deformation and damage to the accommodating part, and two exhaust structures are provided in the pressure stabilizing part. The two exhaust structures are located on the second side of the accommodating space and are respectively located on both sides of the feed pipe along the first direction. After the glass liquid enters the accommodating space, the accommodating space can be divided into two air areas along the first direction, and the pressure of the two air areas can be effectively regulated, thereby avoiding the air on one side of the accommodating space being blocked by the glass liquid, while the glass liquid is still increasing, causing the local pressure of the accommodating part to be too high and deformed.

[0036] Example 1

[0037] Reference Attachment Figure 1A first embodiment of the present invention provides a slot down-draw glass production device, comprising: a receiving portion 1, wherein the receiving portion 1 has a receiving space 11 therein, the receiving space 11 having a first side surface 111 and a second side surface 112 disposed opposite to each other in a longitudinal direction, and the first side surface 111 and the second side surface 112 both extend in a first horizontal direction;

[0038] a discharge portion 2, which is in communication with the first side surface 111 of the accommodating space 11 and extends along the first direction;

[0039] a feed pipe 3, the feed pipe 3 being in communication with the second side surface 112 of the accommodating space 11; and

[0040] The voltage stabilizing part 4 includes two exhaust structures 41, which are respectively connected to the second side surface 112 of the accommodating space 11, and the connection points between the exhaust structure 41 and the accommodating space 11 are respectively located on both sides of the feed pipe 3 along the first direction. The exhaust structure 41 is used to adjust the pressure in the accommodating space 11 so that the pressure in the accommodating space 11 is stabilized at a preset value.

[0041] Specifically, the accommodating portion 1 can be a rectangular shell, with a accommodating space 11 inside the accommodating portion 1. The accommodating space 11 can be a rectangular space extending along the first horizontal direction. The accommodating space 11 can accommodate high-temperature molten glass. The discharge portion 2 is a nozzle for slit down-draw glass production. The discharge portion 2 has a narrow gap. The discharge portion 2 is arranged at the bottom of the accommodating portion 1. The feed pipe 3 can be detachably connected to the accommodating portion 1 to facilitate maintenance and replacement of the discharge portion 2. The discharge portion 2 is connected to the second side 112 of the accommodating space 11. After the accommodating space 11 is gradually filled with molten glass, continue to add molten glass to the accommodating space 11, so that the molten glass at the bottom of the accommodating space 11 can move toward the discharge portion 2, and the molten glass is discharged through the narrow gap of the discharge portion 2 to form a glass plate.

[0042] The voltage stabilizing portion 4 includes two exhaust structures 41. The exhaust structure 41 can be an exhaust pipe provided with a voltage stabilizer 412. The exhaust pipe of the exhaust structure 41 is connected to the accommodating space 11. The pressure in the accommodating space 11 can be adjusted by controlling the voltage stabilizer 412 so that the pressure in the accommodating space 11 is stabilized at a preset value. This preset value can be the atmospheric pressure in the space where the accommodating portion 1 is located. By adjusting the pressure in the accommodating space 11 through the exhaust structure 41, the accommodating portion 1 can be prevented from being deformed by the external pressure, thereby affecting the service life of the accommodating portion 1. In addition, there are two exhaust structures 41, and both exhaust structures 41 are connected to the accommodating space 11. The second side surface 112 of the accommodating portion 1 is connected to the second side surface 112 of the accommodating portion 11, and the connection positions of the exhaust structure 41 and the accommodating space 11 are respectively located on both sides of the feeding pipe 3 along the first direction, that is, the two exhaust structures 41 are respectively located on both sides of the accommodating portion 1 along the first direction, and the feeding pipe 3 is located between the two exhaust structures 41. When the glass liquid is transported into the accommodating space 11 of the accommodating portion 1 through the feeding pipe 3, the glass liquid gradually fills the accommodating space 11 from the middle part of the accommodating space 11 to both sides along the first direction. In this process, the two exhaust structures 41 can respectively control the pressure of the space areas on both sides of the accommodating space 11 along the first direction, and timely discharge the air squeezed by the glass liquid.

[0043] Among them, the exhaust structure 41 is located on the second side 112 of the accommodating space 11, and after the glass liquid enters the accommodating space 11, it will first fill the first side 111 of the accommodating space 11, and then rise to the second side 112 of the accommodating space 11. Since the second side 112 of the accommodating space 11 is the area where the glass liquid is last filled, the exhaust structure 41 set on the second side 112 can maximize the exhaust effect, and the two exhaust structures 41 are respectively located on both sides of the feeding pipe 3 along the first direction, and can respectively adjust the air pressure on the two opposite sides of the accommodating space 11 along the first direction, so as to avoid that after the glass liquid enters the accommodating space 11, the air in the accommodating space 11 is divided into two parts along the first direction, and one part of the air cannot be discharged quickly and effectively, thereby increasing the local pressure in the accommodating space 11 and affecting the service life of the accommodating part 1.

[0044] In the specific production process, at the beginning of production, there is no glass liquid in the feed pipe 3, the accommodating portion 1 and the discharge portion 2, but air. When the glass liquid is injected into the accommodating portion 1 through the feed pipe 3, a part of the air in the accommodating space 11 begins to flow out from the discharge portion 2. Since the viscosity of the glass liquid is relatively high and the opening of the discharge portion 2 is relatively small, after a certain amount of glass liquid is injected, the opening of the discharge portion 2 is sealed by the glass liquid. At this time, the air in the accommodating space 11 cannot flow out through the discharge portion 2. At this time, the air is discharged through the feed pipe 3. When the glass liquid in the feed pipe 3 seals the feed pipe 3 and the air cannot be discharged from the feed pipe 3, the pressure in the accommodating space 11 begins to rise, and the pressure in the accommodating space 11 begins to have a trend greater than the preset value. At this time, the air is discharged through the pressure stabilizing portion 4 to keep the pressure in the accommodating space 11 stable.

[0045] According to the above, an embodiment of the present invention proposes a slit down-draw glass production device, which can adjust the pressure in the accommodating space 11 inside the accommodating portion 1 through the pressure stabilizing portion 4, so that the pressure in the accommodating space 11 is stabilized at a preset value, thereby avoiding the pressure in the accommodating space 11 being too high or too low during the production and discharge process, causing the accommodating portion 1 to be deformed and damaged, and two exhaust structures 41 are provided in the pressure stabilizing portion 4. The two exhaust structures 41 are located on the second side 112 of the accommodating space 11 and are respectively located on both sides of the feed pipe 3 along the first direction. After the glass liquid enters the accommodating space 11, the accommodating space 11 can be divided into two air areas along the first direction, and the pressure of the two air areas can be effectively regulated, thereby avoiding the air on one side of the accommodating space 11 being blocked by the glass liquid, while the glass liquid is still increasing, causing the local pressure of the accommodating portion 1 to be too high and deformed.

[0046] Reference Attachment Figure 1 ,In a specific implementation, the exhaust structure 41 includes: a first air pipe 411 and a pressure stabilizer 412 ;

[0047] One end of the first air pipe 411 is in communication with the second side surface 112 of the accommodating space 11 , and the other end is in communication with the regulator 412 . The regulator 412 is in communication with the external atmosphere.

[0048] Specifically, the exhaust structure 41 includes a first air pipe 411 and a pressure stabilizer 412. The first air pipe 411 is an air duct directly connected to the accommodating space 11. The first air pipe 411 can be a straight pipe. The first air pipe 411 is directly connected to the accommodating portion 1 and can be threadedly connected at the connection point. Sealant or sealing tape can be added to the thread to improve the sealing performance of the first air pipe 411 and the accommodating portion 1. The end of the first air pipe 411 away from the accommodating portion 1 is connected to the pressure stabilizer 412. The pressure stabilizer 412 can be set to a value. When the gas pressure in the accommodating space 11 is greater than this value, the first air pipe 411 can be exhausted through the pressure stabilizer 412; through the first air pipe 411 and the pressure stabilizer 412, the pressure in the accommodating space 11 can be adjusted so that the pressure in the accommodating space 11 will not be greater than the preset value set by the pressure stabilizer 412.

[0049] Reference Attachment Figure 1 In a specific implementation, the exhaust structure 41 further includes:

[0050] The second air pipe 413 has one end in communication with the pressure stabilizer 412 , and the other end in communication with an external high-pressure air pipeline.

[0051] Specifically, the exhaust structure 41 also includes a second air pipe 413, and the side of the pressure regulator 412 facing away from the first air pipe 411 is provided with an air inlet and an air outlet. One end of the second air pipe 413 is connected to the air inlet of the pressure regulator 412, and the other end is connected to the high-pressure air pipeline. When the air in the accommodating space 11 is less than the set value of the pressure regulator 412, the high-pressure air can enter the pressure regulator 412 from the second air pipe 413, and then enter the accommodating space 11 through the first air pipe 411, thereby adjusting the air pressure in the accommodating space 11. It can avoid the air pressure in the accommodating space 11 being too low, causing the accommodating part 1 to deform, and affecting the service life of the accommodating part 1.

[0052] Among them, in the specific production process, the set value of the pressure regulator 412 can also be adjusted to prevent the glass liquid in the accommodating space 11 from entering the pressure regulator 412 from the first air pipe 411, thereby affecting the use of the pressure regulator 412. Specifically, when the glass liquid in the accommodating space 11 gradually increases, before the glass liquid begins to enter the first air pipe 411, the set value of the pressure regulator 412 is a preset value. After the glass liquid begins to enter the first air pipe 411, the set value of the pressure regulator 412 is manually increased. At this time, it is greater than the preset value, so that the pressure value in the first air pipe 411 is less than the set value of the pressure regulator 412. At this time, air is injected into the first air pipe 411 through the second air pipe 413 to increase the pressure in the first air pipe 411, so that the glass liquid in the exhaust pipe no longer increases.

[0053] Among them, in the specific glass liquid discharge process, when the discharge part 2 needs to be replaced, the glass liquid in the accommodating space 11 needs to be emptied first. In this case, the feeding of the feed pipe 3 is stopped first, and then the setting value of the stabilizer 412 is increased. At this time, it is also greater than the preset value, so that the pressure value in the first air pipe 411 is less than the stabilizer setting value. At this time, air is injected into the first air pipe 411 through its two air pipes, and the glass liquid in the first air pipe 411 is pushed out of the first air pipe 411 by high-pressure air, enters the accommodating space 11, and is finally discharged from the discharge part 2; in this process, not only can the glass liquid in the first air pipe 411 be completely discharged, but also high-pressure air can be continuously injected into the accommodating space 11 to avoid negative pressure in the accommodating space 11 during the discharge of the glass liquid, so that the air pressure in the accommodating space 11 remains stable, and the accommodating part 1 is prevented from being deformed due to negative pressure, which affects the service life of the accommodating part 1.

[0054] Reference Attachment Figure 1 In a specific implementation, the exhaust structure 41 further includes:

[0055] The third air pipe 414 has one end in communication with the pressurizer 412 , and the other end in communication with the external atmosphere. The pressurizer 412 is in communication with the external atmosphere through the third air pipe 414 .

[0056] Specifically, the third air pipe 414 can be a pipeline with a heat-insulating effect. One end of the third air pipe 414 is connected to the air outlet of the stabilizer 412, and the other end is connected to the atmosphere. The end of the third air pipe 414 away from the stabilizer 412 can extend vertically upward for a certain distance, away from the operator, and can be used for exhaust; when the stabilizer 412 needs to be exhausted and depressurized, the gas can be exhausted to the outside through the third air pipe 414, and the gas can be discharged to a designated area, which can prevent the high-pressure and high-temperature gas discharged by the stabilizer 412 from scalding the operator.

[0057] Reference Attachment Figure 1 In a specific implementation, the connection point between the feed pipe 3 and the accommodating space 11 is located in the middle of the second side surface 112 along the extension direction of the accommodating space 11.

[0058] Specifically, the connection point between the feed pipe 3 and the accommodating space 11 is located in the middle of the second side surface 112 of the accommodating space 11. When the feed pipe 3 supplies molten glass into the accommodating space 11, the molten glass will flow to both sides at the same time from the connection point between the accommodating space 11 and the feed pipe 3. When this connection point is located in the middle position, the molten glass on both sides of the accommodating space 11 along the first direction can be kept symmetrically distributed as much as possible, so as to facilitate squeezing the air on both sides out of the accommodating space 11 together, so that the air on both sides is discharged at the same time, which can effectively improve work efficiency.

[0059] Reference Attachment Figure 1In a specific implementation, the two exhaust structures 41 are symmetrically arranged along the extension direction of the accommodating space 11 with the feed pipe 3 as the center.

[0060] Specifically, the two exhaust structures 41 are arranged opposite to each other along the first direction and are stacked into sections with the feed pipe 3 as the center. On the premise that the feed pipe 3 is located in the middle of the second side surface 112 of the accommodating space 11, the two symmetrically arranged exhaust structures 41 can correspond to the air areas on both sides. While the air on both sides is discharged as simultaneously as possible, the pressure of the air areas on both sides can be kept stable, thereby protecting the accommodating portion 1.

[0061] Reference Attachment Figure 1 In a specific implementation, the voltage stabilizing unit 4 further includes:

[0062] The heating element has a heating portion capable of generating heat, and the heating portion is arranged around the outer wall of the first air pipe 411.

[0063] Specifically, the voltage stabilizing part 4 also includes a heating element, which can be a resistance wire heating device. The heating part, i.e., the resistance wire, is wrapped around the outer wall of the first air tube 411, which can heat the first air tube 411 and increase the temperature of the glass liquid in the first air tube 411; specifically, during the discharge of the glass liquid, while the glass liquid in the first air tube 411 is pushed out of the first air tube 411 by high-pressure air, the glass liquid in the first air tube 411 is heated, which can reduce the viscosity of the glass liquid and make the process of the glass liquid entering the accommodating space 11 from the first air tube 411 smoother.

[0064] Reference Attachment Figure 1 In a specific implementation, the cooling pipe, the first end of the cooling pipe is connected to the regulator 412, and the second end of the cooling pipe is used to communicate with the external cold air pipeline.

[0065] Specifically, a first end of the cooling pipe is connected to the voltage stabilizer 412 , and a second end thereof is connected to an external cold air pipeline, so that cold air can be added to the first air pipe 411 through the cooling pipe.

[0066] Among them, in the specific production process, air is injected into the first air pipe 411 through the second air pipe 413, and the pressure in the first air pipe 411 is increased. At the same time, the temperature of the glass liquid is lowered by the injected cold air, and the viscosity of the glass liquid is increased, so that the glass liquid condenses quickly and the first air pipe 411 is blocked, thereby preventing the glass liquid from overflowing from the first air pipe 411 and entering the stabilizer 412, affecting the service life of the stabilizer 412.

[0067] Reference Attachment Figure 1 In a specific implementation, the first end of the cooling pipe is connected to the second air pipe 413 , and the cooling pipe is connected to the regulator 412 through the second air pipe 413 .

[0068] Specifically, the cooling pipe is directly connected to the second air pipe 413, and is connected to the regulator 412 through the second air pipe 413. When cold air needs to be injected into the first air pipe 411, the cold air first enters the second air pipe 413. The high-pressure gas in the second air pipe 413 can drive the cold air from the regulator 412 into the first air pipe 411, so that the cooling air can quickly enter the first air pipe 411 to cool the glass liquid.

[0069] Example 2

[0071] Specifically, the production equipment is a slit down-draw glass production equipment. The slit down-draw glass production equipment uses the aforementioned slit down-draw glass production device to make the glass liquid flow out evenly from the slit under pressure to make ultra-thin glass. By squeezing the glass liquid under pressure, the glass liquid pulling process can be made more controllable and the glass quality can be better. The slit down-draw glass production equipment includes a accommodating part 1, a discharge part 2, a feed pipe 3 and a pressure stabilizing part 4. The pressure stabilizing part 4 can stabilize the air pressure inside the accommodating part 1, protect the accommodating part 1, and avoid deformation of the accommodating part 1, which affects the service life of the accommodating part 1.
