Description

Technical Field

[0001] This utility model relates to the field of glass manufacturing technology, and in particular to a stirring device for molten glass. Background Technology

[0002] With the rapid development of display technology, OLED (Organic Light-Emitting Diode) display devices have become the core direction of next-generation display technology due to their advantages such as high contrast, wide color gamut, and flexibility. The performance of OLED devices is highly dependent on the manufacturing quality of their core substrate materials—OLED carrier glass and substrate glass.

[0003] The blade-type stirring rods used in the production of existing OLED carrier glass and substrate glass have significant heat loss in the upper space of the stirring rod, making it impossible to ensure temperature uniformity. This leads to the formation of volatile crystals on the stirring tank cover and stirring rod shaft, and there is a risk that these crystals may fall into the stirring tank at any time. The presence of volatile crystals in the glass melt can affect the quality of the glass sheet during the glass forming process or cause the glass sheet to be scrapped, thus affecting the normal production of glass sheets.

[0004] Therefore, there is an urgent need for a stirring device for molten glass to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a stirring device for molten glass to solve the problem in the prior art where volatiles crystallize in molten glass, thus affecting the normal production of glass sheets.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0007] A stirring device for molten glass, comprising:

[0008] A container with an open end, used to hold molten glass;

[0009] A stirring mechanism, which can be located inside the container, is used to stir the molten glass;

[0010] A collection device, located above the stirring mechanism and opposite to the opening end of the container, is used to collect volatile crystals from the molten glass.

[0011] A lifting mechanism, connected to the stirring mechanism, is used to drive the stirring mechanism to move along the height direction of the container to adjust the height of the stirring mechanism relative to the container.

[0012] Furthermore, the collecting device includes a heat-insulating component and a collecting component connected together. The heat-insulating component is provided with a first collecting groove. The collecting component is located on the side of the heat-insulating component where the first collecting groove is provided. The collecting component and the first collecting groove form a collecting space. The collecting space is connected to the receiving bucket.

[0013] Furthermore, within the collection space, a second collection trough is provided on the side of the collection component facing the insulation component.

[0014] Furthermore, the stirring mechanism includes a stirring rod and multiple stirring components, both ends of which are connected to the stirring rod.

[0015] Furthermore, in the horizontal direction, one end of each of the plurality of stirring elements is located on the same plane, and the other end of each of the plurality of stirring elements is connected to one end of the stirring rod; and / or, the spacing between adjacent stirring elements is equal.

[0016] Furthermore, the stirring mechanism also includes a spiral stirring blade, which is wound around and fixed to the stirring rod, and the spiral stirring blade is located in the space formed by the plurality of stirring elements and the stirring rod.

[0017] Furthermore, two spiral stirring paddles are provided, and a liquid flow plate is also sleeved on the stirring rod. The liquid flow plate is located between the two spiral stirring paddles, and multiple liquid flow holes are provided on the liquid flow plate.

[0018] Furthermore, the spiral stirring paddle is provided with a spiral stirring groove, and the extending direction of the spiral stirring groove is the same as the extending direction of the spiral stirring paddle.

[0019] Furthermore, the stirring device for molten glass also includes a baffle plate, which is inserted through and fixed to the stirring rod and located on the side of the collecting device away from the stirring mechanism.

[0021] The beneficial effects of this utility model are:

[0022] This invention provides a stirring device for molten glass, including a container, a stirring mechanism, a collecting device, and a lifting mechanism. The container has an open end for holding molten glass. The stirring mechanism is located inside the container for stirring the molten glass. The collecting device is located above the stirring mechanism and opposite to the open end of the container for collecting volatile crystals from the molten glass. The lifting mechanism is connected to the stirring mechanism and drives the stirring mechanism to move along the height direction of the container to adjust the height of the stirring mechanism relative to the container. By setting up a lifting mechanism to adjust the height of the stirring mechanism relative to the container, the stirring mechanism can be positioned appropriately for different volumes of molten glass, ensuring thorough stirring and homogenization of the molten glass. Furthermore, the collecting device is positioned opposite the opening of the container, effectively shielding it and reducing the amount of volatile crystals that would result from heat loss at the top of the container.

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or it can be located in between the component.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] This embodiment provides a stirring device for molten glass, which can ensure the stable operation of glass plates during normal production.

[0037] For example, such as Figures 1-3 As shown, the glass molten metal stirring device includes a container (not shown), a stirring mechanism 1, a collecting device 2, and a lifting mechanism 3. The container has an open end for containing the glass molten metal. The stirring mechanism 1 is located inside the container for stirring the glass molten metal. The collecting device 2 is located above the stirring mechanism 1 and is positioned opposite the open end of the container for collecting volatile crystals from the glass molten metal. The lifting mechanism 3 is connected to the stirring mechanism 1 and is used to move the stirring mechanism 1 along the height direction of the container to adjust the height of the stirring mechanism 1 relative to the container. Understandably, by setting the lifting mechanism 3 to adjust the height of the stirring mechanism 1 relative to the container, the stirring mechanism 1 can be positioned appropriately for different volumes of molten glass, enabling thorough stirring and homogenization of the molten glass. Furthermore, the collecting device 2 is positioned opposite the opening of the container, which can shield the opening of the container, reducing the precipitation of volatiles caused by heat loss from the upper part of the container. It also collects the volatile crystals present at the opening of the container, preventing them from falling into the stirring tank. This avoids the presence of volatile crystals in the molten glass affecting the quality of the glass sheet or causing it to be scrapped during the glass sheet forming process, thus ensuring the stable operation of the glass sheet production process.

[0038] Furthermore, by setting up a lifting mechanism 3, it is easy to lift the mixing mechanism 1 out of the container when maintaining it, thus facilitating maintenance.

[0039] Furthermore, such as Figure 2 As shown, the collecting device 2 includes a heat-insulating component 21 and a collecting component 22 connected together. The heat-insulating component 21 is provided with a first collecting groove (not shown in the figure), and the collecting component 22 is located on the side of the heat-insulating component 21 where the first collecting groove is provided. The collecting component 22 and the first collecting groove form a collecting space (not shown in the figure), which is connected to the receiving tank. It can be understood that by forming the collecting space, the heat-insulating component 21 and the collecting component 22 are used to cover the open end of the receiving tank, which is equivalent to the end cap of the receiving tank. This reduces the heat exchange between the high-temperature glass melt and the outside environment, avoids a sudden drop in local temperature that would cause the viscosity of the glass melt to increase or crystallize, and allows the volatiles in the glass melt to condense rapidly on the heat-insulating component 21. The collecting space collects the crystallized volatiles and prevents them from falling into the glass melt, which would affect the production quality. In this embodiment, the heat-insulating component 21 includes, but is not limited to, existing irregularly shaped heat-insulating bricks, and the collecting component 22 includes, but is not limited to, existing platinum cover bricks.

[0040] Furthermore, within the collection space, a second collection trough (not shown in the figure) is provided on the side of the collection component 22 facing the insulation component 21. It can be understood that by providing the second collection trough, when there are a large amount of volatile crystals condensed on the insulation component 21, the volatile crystals falling off the insulation component 21 can be collected, preventing the volatile crystals from falling into the container.

[0041] Furthermore, such as Figure 2 and Figure 3 As shown, the stirring mechanism 1 includes a stirring rod 11 and multiple stirring elements 12, with both ends of the multiple stirring elements 12 connected to the stirring rod 11. It can be understood that the stirring rod 11 can drive the multiple stirring elements 12 to move, thereby improving the uniformity of the stirring of the molten glass.

[0042] Furthermore, such as Figure 2 and Figure 3 As shown, in the axial direction of the stirring rod 11, that is, in the vertical direction, the distance between the stirring element 12 and the stirring rod 11 first increases and then decreases, that is, the stirring element 12 is concave relative to the stirring rod 11, so as to improve the stirring effect of the stirring element 12 on the glass liquid.

[0043] In this embodiment, in the horizontal direction, one end of each of the multiple stirring elements 12 is located on the same plane, and the other end of each of the multiple stirring elements 12 is connected to one end of the stirring rod 11, that is, the multiple stirring elements 12 are located at the same height in the axial direction of the stirring rod 11. Of course, in other embodiments, the multiple stirring elements 12 may be located at different heights in the axial direction of the stirring rod 11.

[0044] In this embodiment, the spacing between adjacent stirring elements 12 is equal, that is, multiple stirring elements 12 are evenly spaced on the stirring rod 11 to improve the uniformity of stirring the molten glass by multiple stirring elements 12. Of course, in other embodiments, the spacing between adjacent stirring elements 12 may not be equal, as long as it meets the actual use requirements, and this embodiment does not make specific limitations.

[0045] In this embodiment, the stirring device for molten glass also includes a stirring drive mechanism 6, which is connected to the stirring mechanism 1 and to the lifting mechanism 3. The stirring drive mechanism 6 drives the stirring mechanism 1 to move, and the lifting mechanism 3 drives both the stirring drive mechanism 6 and the stirring mechanism 1 to move. Specifically, the stirring drive mechanism 6 is connected to the other end of the stirring rod 11, causing the stirring rod 11 to rotate, thereby realizing the movement of the entire stirring mechanism 1.

[0046] In this embodiment, the stirring drive mechanism 6 may include a drive motor (not shown in the figure) and two meshing bevel gears (not shown in the figure) connected in sequence. The output end of the drive motor is connected to one of the bevel gears, and the other bevel gear is sleeved and fixed to the other end of the stirring rod 11 to change the driving direction of the drive motor, thereby driving the stirring rod 11 to rotate. The axis of the output end of the drive motor is perpendicular to the axis of the stirring rod 11. The drive motor includes, but is not limited to, a servo motor. Of course, in other embodiments, the stirring drive mechanism 6 may also include other types of motors and other types of commutators, as long as they meet the actual use requirements. This embodiment does not specifically limit this.

[0047] Furthermore, the glass molten metal stirring device also includes a baffle plate 4, which is inserted through and fixed to the stirring rod 11 and located on the side of the collecting device 2 away from the stirring mechanism 1. It is understood that by setting the baffle plate 4 on the side of the collecting device 2 away from the stirring mechanism 1, it vertically blocks the gap between the stirring rod 11 and the collecting device 2, preventing foreign objects from falling into the glass molten metal and affecting production quality.

[0048] Furthermore, the stirring mechanism 1 also includes a spiral stirring paddle 13, which is wound around and fixed to the stirring rod 11, and is located within the space formed by the plurality of stirring elements 12 and the stirring rod 11. It can be understood that by setting the spiral stirring paddle 13 within the space formed by the plurality of stirring elements 12 and the stirring rod 11, the stirring effect on the molten glass is improved without occupying external space, and it is also beneficial to achieve the compactness of the stirring mechanism 1.

[0049] Furthermore, two spiral stirring paddles 13 are provided, and a liquid flow plate 14 is also sleeved on the stirring rod 11. The liquid flow plate 14 is located between the two spiral stirring paddles 13, and multiple liquid flow holes (not shown in the figure) are provided on the liquid flow plate 14. By providing the liquid flow plate 14, it is convenient for the glass liquid to pass through the liquid flow holes during the stirring process, which improves the fluidity of the glass liquid in the middle region and further improves the uniformity of the stirring of the glass liquid.

[0050] Of course, in other embodiments, only one spiral impeller 13 may be provided, and the liquid flow plate 14 may be sleeved on the spiral impeller 13, as long as it meets the actual use requirements. This embodiment does not make specific limitations.

[0051] Furthermore, the spiral stirring paddle 13 is provided with a spiral stirring groove (not shown in the figure), and the extending direction of the spiral stirring groove is the same as the extending direction of the spiral stirring paddle 13. It can be understood that by providing a spiral stirring groove, the fluidity of the molten glass is improved, thereby further improving the uniformity of the stirring of the molten glass.

[0052] Furthermore, it can be inferred that the stirring component 12, the spiral stirring paddle 13, and the liquid flow plate 14 can stir the glass liquid from different heights and angles in all directions, further improving the uniformity of the stirring of the glass liquid.

[0053] For example, such as Figure 1 and Figure 3 As shown, the glass molten metal stirring device also includes a support mechanism 5, which includes a mounting part 51 and a limiting part 53. The lifting mechanism 3 is installed on the support mechanism 5 and located between the mounting part 51 and the limiting part 53. Specifically, the support mechanism 5 also includes a support column 52, with the mounting part 51 and the limiting part 53 located at both ends of the support column 52. It can be understood that by providing the mounting part 51, the mounting part 51 can be fixed to the ground or other installation positions, ensuring the stability of the glass molten metal stirring device. By providing the limiting part 53 in conjunction with the mounting part 51, the upper limit of the lifting mechanism 3, i.e., the lifting upper limit of the stirring mechanism 1, is limited, preventing the lifting mechanism 3 from detaching from the support mechanism 5 and ensuring the stability of the lifting mechanism 3's operation.

[0054] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
