Abstract
Description
Technical Field
[0001] This invention relates to the field of glass melting furnaces, and particularly to a hook brick structure and a glass melting furnace. Background Technology
[0002] Hook bricks are a crucial component of the glass melting furnace structure. Their main functions are to support the weight of the upper brick structure, seal the interior and exterior spaces of the furnace, protect the steel support plate from high temperatures and flame damage, and ensure the safety of the entire furnace structure. The support plate, made of low-carbon Q235B steel, is prone to carbonization and oxidation under high temperatures and flame damage, leading to reduced strength and potentially fatal consequences for the furnace structure. Therefore, protecting the support plate is paramount to furnace safety. In existing technologies, the breast wall, hook bricks, and pool wall form a sealed space, separating the interior from the exterior of the furnace. However, in the existing structure, the support plate is installed 90mm to 100mm above the pool wall. Because the support plate is higher than the pool wall, the hook head of the hook brick protrudes downwards from the lower surface of the brick. In the later stages of furnace operation, the pool wall is eroded by the molten glass and gradually becomes thinner (the pool wall needs to be reinforced with bricks multiple times in the later stages of furnace operation). When the old pool wall is eroded away, the support plate will be exposed to the high-temperature molten glass and suffer from burning and oxidation. The strength of the steel structure is affected, and in severe cases, it will threaten the safety of the furnace. During the operation of the furnace, the hook head of the hook brick often breaks, failing to protect the support plate. The support plate is directly exposed to the flame space, burned and carbonized, and its strength is affected, which will also threaten the safety of the furnace in severe cases. Summary of the Invention
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a hook brick structure that can eliminate the hidden danger of the iron support plate being easily burned, and has high safety.
[0004] The present invention also proposes a glass melting furnace having the above-mentioned hook brick structure.
[0005] According to a first aspect of the present invention, a hook brick structure includes:
[0006] pool wall;
[0007] A column is installed on the outside of the pool wall;
[0008] A support plate is installed on the column, and the upper surface of the support plate is lower than the upper surface of the pool wall;
[0009] The hook brick body includes a brick body and a hook head. The brick body is located on the upper surface of the support plate, and the hook head is located at one end of the brick body near the pool wall. The hook head is higher than the lower surface of the brick body and extends to the top of the pool wall and connects with the pool wall.
[0010] The breast wall is built on the upper part of the brickwork.
[0011] The hook brick structure according to embodiments of the present invention has at least the following beneficial effects:
[0012] The traditional structure of installing the support plate at a position 90mm to 1mm above the pool wall has been optimized so that the upper surface of the support plate is lower than the upper surface of the pool wall. Furthermore, the traditional structure of the hook protruding downwards from the brick has been optimized so that the hook protrudes above the lower surface of the brick. This ensures that even if the pool wall is eroded in the later stages of the melting furnace, the support plate will not be exposed to the high-temperature molten glass. Additionally, even if the hook breaks during furnace operation, the support plate will not be exposed to the flame space. This eliminates the risk of direct damage to the support plate from the high-temperature molten glass and flames, ensuring the safety of the furnace operation throughout the entire furnace period.
[0013] According to some embodiments of the present invention, the height difference h1 between the upper surface of the support plate and the upper surface of the pool wall is in the range of 90mm≤h1≤120mm.
[0014] According to some embodiments of the present invention, the lower end of the hook head is provided with a slope, the slope extends downward in a direction away from the pool wall to the lower surface edge of the brick body, and the inclined top of the slope is higher than the upper surface of the pool wall.
[0015] According to some embodiments of the present invention, the upper end of the hook head is provided with an arc transition surface, which extends to the upper surface edge of the brick.
[0016] According to some embodiments of the present invention, the column is provided with a limiting structure, which abuts against the brick body downward.
[0017] According to some embodiments of the present invention, the upper surface of the brick is recessed at the end away from the hook head, and the limiting structure abuts against the step.
[0018] According to some embodiments of the present invention, a sealing portion is provided protruding from the upper surface of the pool wall, a gap is provided between the hook head and the upper surface of the pool wall, and the hook head abuts against the side wall of the sealing portion to maintain a seal with the sealing portion.
[0019] According to some embodiments of the present invention, the lower end of the hook head is provided with a limiting surface, the limiting surface is parallel to the upper surface of the pool wall, and the projection of the limiting surface on the horizontal plane at least partially coincides with the projection of the upper surface of the pool wall on the horizontal plane.
[0020] According to some embodiments of the present invention, the sealing part is configured as a joint-blocking brick, and the end of the hook away from the brick body is provided with a vertical abutting surface, which is in contact with the side wall of the joint-blocking brick.
[0021] According to a second aspect of the present invention, a glass melting furnace includes the hook brick structure described in the first aspect of the present invention.
[0022] According to an embodiment of the glass melting furnace of the present invention, the traditional structure of installing the support plate at a position 90 mm to 1 mm above the pool wall is optimized so that the upper surface of the support plate is lower than the upper surface of the pool wall. Furthermore, the traditional structure of the hook protruding downwards from the brick is optimized so that the hook is higher than the lower surface of the brick. This ensures that even if the pool wall is eroded in the later stages of the melting furnace, the support plate will not be exposed to the high-temperature molten glass. Also, if the hook breaks during furnace operation, the support plate will not be exposed to the flame space. This eliminates the risk of direct damage to the support plate from the high-temperature molten glass and flame, ensuring the safety of the melting furnace operation throughout the entire furnace period.
[0023] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.
[0038] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.
[0039] In the existing structure, the support plate is installed 90mm to 100mm above the pool wall. Because the support plate is higher than the pool wall, the hook head of the hook brick protrudes downwards from the lower surface of the brick. In the later stages of furnace operation, the pool wall is eroded by the molten glass and gradually becomes thinner (the pool wall needs to be reinforced with bricks multiple times in the later stages of furnace operation). When the old pool wall is eroded away, the support plate will be exposed to the high-temperature molten glass and suffer from burning and oxidation by the high-temperature molten glass. The strength of the steel structure is affected, and in severe cases, it will threaten the safety of the furnace. During the operation of the furnace, the hook head of the hook brick often breaks, failing to protect the support plate. The support plate is directly exposed to the flame space, burned and carbonized, and its strength is affected, which will also threaten the safety of the furnace in severe cases.
[0040] Therefore, this invention proposes a hook brick structure and a glass melting furnace, which can effectively improve the above-mentioned problems.
[0041] The following reference Figures 1 to 4 The hook brick structure and glass melting furnace according to embodiments of the present invention are described.
[0042] According to a first aspect of the present invention, the hook brick structure includes: a pool wall 100, a column 200, a support plate 300, a hook brick body 400, and a breast wall 500. It should be noted that in the later stages of the melting furnace, the pool wall 100 is eroded by the high-temperature molten glass, requiring the application of new bricks 120 to the outside of the pool wall 100 for maintenance.
[0043] For example, the column 200 is located on the outside of the pool wall 100, and the inside of the pool wall 100 is high-temperature molten glass.
[0044] The support plate 300 is installed on the column 200. The upper surface of the support plate 300 is lower than the upper surface of the pool wall 100. Obviously, the support plate 300 is located on the outside of the pool wall 100. It should be noted that the upper surface of both the support plate 300 and the upper surface of the pool wall 100 are horizontal. Both the support plate 300 and the column 200 are steel structures.
[0045] The hook brick body 400 is an integral structure, including a brick body 401 and a hook head 402. The brick body 401 is located on the upper surface of the support plate 300, and the lower surface of the brick body 401 is lower than the upper surface of the pool wall 100. The hook head 402 is located at the end of the brick body 401 near the pool wall 100, and the hook head 402 is higher than the lower surface of the brick body 401. The hook head 402 extends to the top of the pool wall 100 and connects with the pool wall 100.
[0046] The breast wall 500 is built on top of the brick body 401. The breast wall 500, the hook brick body 400, and the pool wall 100 separate the interior and exterior spaces of the melting furnace.
[0047] The hook brick structure of this invention optimizes the position of the support plate 300 relative to the pool wall 100 and the structure of the hook brick body 400. In the traditional structure, the support plate 300 is installed at a position 90mm to 100mm higher than the pool wall, which is optimized so that the upper surface of the support plate 300 is lower than the upper surface of the pool wall 100. In the traditional structure, the hook head 402 protrudes downward from the brick body 401, which is optimized so that the hook head 402 is higher than the lower surface of the brick body 401. This ensures that even if the pool wall 100 is eroded in the later stage of the melting furnace, the support plate 300 will not be exposed to the high-temperature glass melt. In the event that the hook head 402 breaks during the operation of the melting furnace, the support plate 300 will not be exposed to the flame space. This eliminates the hidden danger of the high-temperature glass melt and flame directly burning the support plate 300 and ensures the safety of the melting furnace operation throughout the entire furnace period.
[0048] Reference Figure 1As shown, in some embodiments of the invention, the height difference h1 between the upper surface of the support plate 300 and the upper surface of the pool wall 100 ranges from 90mm ≤ h1 ≤ 120mm. It is understood that to prevent the support plate 300 from being exposed to the high-temperature molten glass or to the flame space, the upper surface of the support plate 300 needs to be lower than the upper surface of the pool wall 100, utilizing the height difference to protect the support plate 300. However, if the height difference between the upper surface of the support plate 300 and the upper surface of the pool wall 100 is too small, it will negatively impact the support plate. The protective effect of plate 300 will be relatively poor. If the height difference between the upper surface of the iron plate 300 and the upper surface of the pool wall 100 is too large, it will encroach on the space outside the pool wall 100. As a result, after the pool wall 100 is eroded in the later stage of the melting furnace, the operating space for attaching new bricks 120 on the outside of the pool wall 100 will be smaller. Therefore, the height difference between the upper surface of the iron plate 300 and the upper surface of the pool wall 100 is preferably 90mm to 120mm. This can ensure a good protective effect on the iron plate 300 and avoid encroaching on the space for attaching new bricks 120 in the later stage of the melting furnace.
[0049] Reference Figures 1 to 3 As shown, in some embodiments of the invention, the lower end of the hook 402 is provided with a slope 403. The slope 403 extends downward in a direction away from the pool wall 100 to the lower surface edge of the brick 401. The inclined top of the slope 403 is higher than the upper surface of the pool wall 100. It is understood that after the pool wall 100 is eroded in the later stage of the melting furnace, it is necessary to attach new bricks 120 to the outer surface of the pool wall 100 for maintenance. In order to provide more space for attaching new bricks 120, this embodiment provides a slope 403 at the lower end of the hook 402, so that the slope 403 extends downward in a downward direction to the lower surface edge of the brick 401, so that the lower end of the hook 402 and the lower surface of the brick 401 are transitioned through the slope 403, thereby avoiding the new bricks 120. Obviously, since the lower surface of the brick 401 is lower than the upper surface of the pool wall 100, if the lower end of the hook 402 and the lower surface of the brick 401 are connected by a vertical surface, the upper space reserved for the new brick 120 will be smaller. As a result, the number of layers that the new brick 120 can be laid will be reduced, or the top of the new brick 120 will not be able to extend to the upper surface of the pool wall 100. That is, the height of the new brick 120 will be lower than the height of the pool wall 100. If the top of the pool wall 100 is eroded by the molten glass later, there will be a risk of the molten glass overflowing.
[0050] Reference Figure 2 As shown, in some embodiments of the invention, the upper end of the hook 402 is provided with an arc transition surface 404, which extends to the edge of the upper surface of the brick body 401. That is, there is an arc transition between the upper end of the hook 402 and the brick body 401, which can avoid stress concentration and cause the hook 402 to break, and extend the service life of the hook brick body 400.
[0051] Reference Figure 1 and Figure 2 As shown, in some embodiments of the invention, the column 200 is provided with a limiting structure 210. Specifically, the limiting structure 210 is located on the side of the brick 401 away from the hook head 402. The limiting structure 210 abuts against the brick 401 downwards, thereby cooperating with the support plate 300 to vertically limit the brick 401, preventing the center of gravity of the hook brick body 400 and the breast wall 500 as a whole from shifting towards the pool wall 100, which would cause the breast wall 500 and the hook brick body 400 to tilt towards the pool wall 100, thus improving structural stability. In a further embodiment, a step 405 is recessed on the upper surface of the brick 401 at the end away from the hook 402. The limiting structure 210 abuts against the step 405 downwards, thereby abutting against the brick 401 downwards. By setting the step 405, the installation of the limiting structure 210 can be facilitated. It is understood that the breast wall 500 is built on the upper end of the brick 401. During the construction of the breast wall 500, it is often impossible to accurately determine the position of the breast wall 500. In order to avoid the situation where the breast wall 500 occupies the installation space of the limiting structure 210, this embodiment sets a step 405 on the upper surface of the brick 401 at the end away from the hook 402. The limiting structure 210 abuts against the step 405 downwards to abut against the brick 401 downwards. In this way, when the breast wall 500 is built, it is only necessary to make the breast wall 500 avoid the upper side of the step 405 to avoid the situation where the breast wall 500 occupies the installation space of the limiting structure 210. Specifically, in this embodiment, the limiting structure 210 includes an angle steel, which is fixed on the column 200. It is conceivable that the angle steel can directly abut against the step 405, or it can indirectly abut against the step 405 through a pad. The advantage of indirectly abutting against the step 405 through a pad is that it allows for a certain installation error of the angle steel and a certain processing error of the step 405, and the pad eliminates the influence of the above two errors.
[0052] Reference Figure 1 and Figure 2 As shown, in some embodiments of the invention, a sealing part 110 is provided protruding from the upper surface of the pool wall 100. A gap is provided between the hook head 402 and the upper surface of the pool wall 100, and the hook head 402 abuts against the side wall of the sealing part 110 to maintain a seal with the sealing part 110. It is conceivable that the pool wall 100 is in long-term contact with high-temperature molten glass and is prone to thermal expansion. If the hook head 402 directly abuts against the upper surface of the pool wall 100, the upward expansion of the pool wall 100 due to heat will squeeze the hook head 402 and cause the hook head 402 to break. Therefore, in this embodiment, a gap is provided between the hook head 402 and the upper surface of the pool wall 100 to provide a certain buffer space for the expansion of the pool wall 100. The seal between the hook head 402 and the pool wall 100 is achieved by the sealing part 110 protruding from the upper surface of the pool wall 100.
[0053] Reference Figure 1 and Figure 2 As shown, in some embodiments of the invention, the lower end of the hook 402 is provided with a limiting surface 406. The limiting surface 406 is parallel to the upper surface of the pool wall 100, and the projection of the limiting surface 406 on the horizontal plane at least partially coincides with the projection of the upper surface of the pool wall 100 on the horizontal plane. Thus, when the pool wall 100 expands due to heat, once the pool wall 100 expands to contact the hook 402, the limiting surface 406 can increase the contact area between the pool wall 100 and the hook 402, avoiding excessive stress concentration and reducing the risk of the hook 402 breaking. It is understood that the limiting surface 406 of the hook 402 and the lower surface of the brick 401 are both horizontal, and the height difference h2 between the limiting surface 406 of the hook 402 and the lower surface of the brick 401 has a range of 90 mm. h1, to leave a gap between the limiting surface 406 and the upper surface of the pool wall 100.
[0054] Reference Figure 1 and Figure 2 As shown, in some embodiments of the invention, the sealing part 110 is configured as a joint-blocking brick, which is built on the upper surface of the pool wall 100. The end of the hook 402 away from the brick body 401 is provided with a vertical abutment surface 407. The abutment surface 407 is in contact with the side wall of the joint-blocking brick to maintain the seal between the hook 402 and the joint-blocking brick. By setting the abutment surface 407 to fit the side wall of the joint-blocking brick, the contact area is increased, the sealing effect is improved, and the situation of excessive stress concentration can also be avoided.
[0055] In one specific embodiment, the hook brick structure includes: a pool wall 100, a column 200, a support plate 300, a hook brick body 400, and a breast wall 500. A retaining brick protrudes from the upper surface of the pool wall 100; the column 200 is located on the outer side of the pool wall 100, and a limiting structure 210, including angle steel, is provided on the column 200; the support plate 300 is installed on the side of the column 200 near the pool wall 100, the upper surface of the support plate 300 is horizontal, and the upper surface of the support plate 300 is lower than the upper surface of the pool wall 100, with the height difference h1 between the upper surface of the support plate 300 and the upper surface of the pool wall 100 falling within a certain range. The circumference is: 90mm≤h1≤120mm; the hook brick body 400 is an integral structure, including a brick body 401 and a hook head 402. The brick body 401 is located on the upper surface of the support plate 300. A step 405 is recessed at the end of the upper surface of the brick body 401 away from the hook head 402. An angle iron abuts against the step 405 downwards to abut against the brick body 401. The hook head 402 is located at the end of the brick body 401 near the pool wall 100, and the hook head 402 is higher than the brick body 401. On the lower surface of 01, hook head 402 extends to the top of pool wall 100. The lower end of hook head 402 has a slope 403 and a limiting surface 406, while the upper end of hook head 402 has an arc-shaped transition surface 404. Hook head 402 also has an abutment surface 407, which is vertically located at the end of hook head 402 away from brick body 401. Abutment surface 407 adheres to the side wall of the retaining brick to maintain a seal between hook head 402 and retaining brick. One end of the arc-shaped transition surface 404 extends to the abutment surface 406. The upper end of the contact surface 407 extends to the upper surface edge of the brick body 401. The limiting surface 406 extends horizontally outward from the lower end of the contact surface 407 away from the joint-blocking brick. The inclined surface 403 extends from the end of the limiting surface 406 away from the joint-blocking brick to the lower surface edge of the brick body 401, and the inclined surface 403 extends downward in a direction away from the limiting surface 406.
