Description

Technical Field

[0001] This utility model relates to the field of refractory materials technology, specifically to a support brick for a channel in a liquid crystal substrate glass kiln. Background Technology

[0002] Glass furnaces are essential equipment in the glass industry, mainly used for melting, clarifying, and homogenizing raw materials to ensure that the discharged glass melt meets production needs. In the manufacturing process of TFT-LCD substrate glass, the platinum channel area is in a high-temperature and high-humidity environment for a long time. In particular, the platinum-rhodium alloy material of the body must be fully filled and sealed under this condition to avoid direct or indirect contact between the material and oxygen, which would cause continuous oxidation and volatilization reactions, affecting or even threatening the overall strength and reliability of the channel equipment. In addition, the temperature gradient formed by the large temperature difference between the inside and outside has a certain stimulating effect on the formation of platinum-rhodium defects. Therefore, the outside is usually wrapped with a layer of refractory material for support and heat insulation protection.

[0003] During the current heating process of the platinum channel (operating temperature approximately 1600℃-1680℃), the platinum channel is supported by refractory bricks. As the temperature continues to rise, the platinum channel and the refractory material will expand. The expansion coefficients of the platinum channel, the refractory material, and the mechanism connecting the refractory material are different. Therefore, during the heating stage, the channel cannot expand freely in the refractory material, resulting in channel compression deformation and damage. Alternatively, during the heating stage, the channel may over-expand in the mechanism connecting the refractory material, causing the channel support bricks to separate and form "red leakage".

[0004] Although existing technologies are striving to find refractory materials with a thermal expansion coefficient similar to that of platinum channels, the large temperature difference between the inner and outer surfaces of the refractory materials makes it difficult to achieve the same thermal expansion coefficient. Therefore, existing platinum channel support bricks are inevitably difficult to fully adapt to platinum channels, and there is still compression and friction between the platinum channels and the refractory materials. Therefore, this utility model aims to improve the reliability of the equipment and reduce the compression or friction on the platinum channels by designing the structure of the external support bricks. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a support brick for a glass kiln channel for liquid crystal substrates, thus achieving the goal of solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A support brick for a glass furnace channel of a liquid crystal substrate, the support brick comprising a brick body and a connecting part made of the same material, both the brick body and the connecting part being groove-shaped structures with openings at the top and two ends, the connecting part being integrally wrapped around the brick body, one side wall of the connecting part being higher than the top surface of the brick body and the other side wall being lower than the top surface of the brick body, the two end faces of the connecting part being misaligned with the two end faces of the brick body, the end of the connecting part and the end of the brick body respectively forming a first protrusion and a first groove, the top of the connecting part and the top of the brick body respectively forming a second protrusion and a second groove; the support brick is provided with a connecting hole extending from the top of the brick body to the bottom surface of the connecting part.

[0008] In use, two support bricks are joined together to form a support unit for the platinum channel, and multiple support units are connected to form a support structure for the platinum channel.

[0009] Furthermore, the support structure has a cylindrical receiving space.

[0010] Furthermore, the depth of the first groove is greater than the length of the first boss, and the depth of the second groove is greater than the height of the second boss.

[0011] Furthermore, it also includes a connecting rod for connecting the support unit, wherein at least a portion of the outer wall of the connecting rod is provided with external threads, and when multiple support units are connected, the connecting rod passes through multiple brick bodies arranged in the same straight line, and a limiting ring for limiting each brick body is threadedly connected to the connecting rod.

[0012] Furthermore, the limiting ring includes a first half-ring and a second half-ring, both of which are half-circular bodies. After the first half-ring and the second half-ring are joined together, they form a circular limiting ring. The inner ring surfaces of the first half-ring and the second half-ring are provided with internal threads.

[0013] Furthermore, the brick body has through holes arranged near the receiving space, and countersunk holes are provided at both ends of the through holes. When two adjacent brick bodies come into contact, the countersunk holes on the two brick bodies form a cylindrical space for receiving the limiting ring. The length of the cylindrical space matches the length of the limiting ring.

[0014] The beneficial effects of this utility model embodiment are as follows:

[0015] 1. The connecting part of the support brick of this utility model is connected to the brick body to form a first boss and a first groove, a second boss and a second groove. These allow the support bricks to be connected to each other to form a whole. Even if it expands or slips due to heat, the platinum channel will not be exposed to the air due to the restriction of the boss and groove, thus improving the stability of the device.

[0016] 2. This utility model is equipped with a connecting rod and a limiting ring. During the expansion of the platinum channel, the limiting ring also expands, moving the refractory material. Each section of refractory material expands in relation to a portion of the platinum channel, reducing friction caused by different expansion coefficients, further improving the reliability of the device, and reducing the compression or friction on the platinum channel.

[0017] 3. This utility model achieves positioning through a structure of two semicircles, which is more convenient to use, reduces the number of steps, and improves efficiency compared to a single ring. Attached Figure Description

[0024] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] See Figures 1 to 5 This utility model discloses a support brick for a glass furnace channel for liquid crystal substrates, such as... Figure 1As shown, the supporting brick includes a brick body 1 and a connecting part 2 made of the same refractory material. Both the brick body 1 and the connecting part 2 are groove-shaped structures with openings at the top and left and right ends. The interior of the brick body 1 is a semi-circular receiving space for accommodating the platinum channel. When two supporting bricks are joined together, a circular receiving space is formed. The front and rear outer surfaces of the brick body 1 are vertical rectangular planes. The connecting part 2 is integrally wrapped around the brick body 1. One side wall of the connecting part 2 is higher than the top surface of the brick body 1, and the other side wall is lower than the top surface of the brick body 1. The length of the connecting part 2 is similar to that of the brick body 1. The two end faces of the connecting part 2 are offset from the two end faces of the brick body 1. The ends of the connecting part 2 and the ends of the brick body 1 respectively form a first boss 3 and a first groove 4. The top of the connecting part 2 and the top of the brick body 1 respectively form a second boss 5 and a second groove 6. The supporting brick is provided with a connecting hole 7 that extends from the top of the brick body 1 to the bottom surface of the connecting part 2. When two supporting bricks are joined together, the connecting hole 7 allows the connecting piece 8 to pass through, which is used to connect the two supporting bricks.

[0026] like Figure 2 As shown, in use, two support bricks are joined together to form a support unit for the platinum channel, and multiple support units are connected sequentially from left to right to form a support structure for the platinum channel.

[0027] The depth of the first groove 4 is greater than the length of the first boss 3, and the depth of the second groove 6 is greater than the height of the second boss 5. The term "height" refers to... Figure 1 The distance between the top of the rear side wall of the connecting part 2 and the top surface of the brick body 1 allows the present invention to be connected smoothly, and even if the support units slide relative to each other, the first protrusion 3 and the second protrusion 5 can cover the gap between the support bricks, so as not to expose the platinum channel to the air.

[0028] When the platinum channel expands due to heat, the supporting bricks connecting the upper and lower parts only increase the space they can accommodate, and the impact on the platinum channel is not serious. However, because the platinum channel is relatively long, the elongation along its length is large, while the elongation of the supporting bricks made of refractory material is smaller. This can cause compression on the platinum channel at one end, or cause the platinum channel to slide relative to the supporting bricks due to compression, resulting in friction. Such compression or friction is large and can easily lead to damage to the platinum channel. Therefore, this utility model also needs to solve the problem of how to make the supporting unit formed by the supporting bricks elongate together with the platinum channel when it is heated.

[0029] like Figure 3 and Figure 4As shown, it also includes a connecting rod 9 for connecting the support unit. At least a portion of the outer wall of the connecting rod 9 is provided with an external thread 10. When multiple support units are connected, the connecting rod 9 passes through multiple brick bodies 1 arranged in the same straight line. A limiting ring 11 for limiting each brick body 1 is connected to the connecting rod 9 via the external thread 10.

[0030] like Figure 3 As shown, the brick body 1 has through holes 12 arranged near the receiving space. The two ends of the through holes 12 are respectively provided with countersunk holes 13. When two adjacent support bricks come into contact, the countersunk holes 13 on the two support bricks form a columnar space for receiving the limiting ring 11. The length of the columnar space matches the length of the limiting ring 11.

[0031] The connecting rod 9 is preferably made of the same material as the platinum channel or a metal material with a thermal expansion coefficient slightly greater than that of the platinum channel. When the platinum channel is heated, because the connecting rod 9 is close to the platinum channel, the temperature difference between the two is not large, and the elongation can be similar to that of the platinum channel. In addition, the limiting ring 11 drives the support brick to move, reducing the compression or friction between the support brick and the platinum channel.

[0032] The aforementioned friction or compression occurs because, when the support bricks do not actively slide, the difference in elongation between each support brick and the corresponding platinum channel accumulates as the platinum channel expands, ultimately resulting in a large compression state or relative sliding. This invention utilizes the characteristic of the connecting rod 9 also expanding due to heat, and uses the limiting ring 11 to drive the support bricks to actively slide. This active sliding, when the platinum channel expands due to heat, causes each support brick to slide in the same direction, thus reducing the cumulative difference in thermal expansion elongation between the platinum channel and the support bricks. Only the difference in thermal expansion elongation between each support brick and the corresponding platinum channel segment is considered, reducing compression and friction and improving the stability of the device.

[0033] like Figure 5 As shown, the limiting ring 11 includes a first half-ring 14 and a second half-ring 15. Both the first half-ring 14 and the second half-ring 15 are half-rings. After the first half-ring 14 and the second half-ring 15 are joined together, they form a ring-shaped limiting ring 11. The inner ring surfaces of the first half-ring 14 and the second half-ring 15 are provided with internal threads.

[0034] The above technical solution achieves the limiting position through a structure of two semicircles, eliminating the need to rotate the limiting ring from one end of the connecting rod. Instead, it can be directly connected near the support, making it more convenient to use, reducing the number of steps, and improving efficiency compared to a single ring.

[0035] After using the above structure, the probability of leakage is reduced by 11.7%, the service life of the platinum channel is extended to 34 months, and the cost of using the platinum channel is reduced by 6.72%.

[0036] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
