Description

Technical Field

[0001] The invention relates to the field of glass melting furnaces, and in particular to a hook brick structure and a glass melting furnace. Background Art

[0002] The hook brick is an important key part of the glass melting furnace structure. Its main function is to support the weight of the upper brick structure wall, seal the internal and external spaces of the melting furnace, protect the iron support plate steel structure from high temperature and flame burns, and ensure the safety of the entire melting furnace structure. The function of the iron support plate is mainly to support the weight of the upper brick structure of the entire kiln body. The iron support plate is made of low-carbon steel Q235B. It is easy to carbonize and oxidize under high temperature and flame burns, and its strength is reduced, which will have a fatal impact on the safety of the entire melting furnace structure. Therefore, protecting the safety of the iron support plate is crucial to the safety of the melting furnace. In the prior art, the breast wall, hook bricks, and pool wall form an enclosed space that separates the internal and external spaces of the melting furnace. However, in the existing structure, the iron support plate is installed at a position 90mm to 100mm higher than the pool wall, and because the iron support plate is higher than the pool wall, the hook head of the hook brick will protrude downward from the lower surface of the brick body. In the later stage of the operation of the melting furnace, the pool wall is eroded by the glass liquid and gradually becomes thinner (the pool wall needs to be tied with bricks for maintenance many times in the later stage of the melting furnace). The old pool wall is eroded, and the iron support plate is exposed to the high-temperature glass liquid, and is burned and oxidized by the high-temperature glass liquid. The strength of the steel structure is affected, which may threaten the safety of the melting furnace in severe cases. During the operation of the melting furnace, the hook head of the hook brick often breaks, and the iron support plate cannot protect the iron support plate. The iron support plate is directly exposed to the flame space, burned and carbonized, and its strength is affected, which may threaten the safety of the melting furnace in severe cases. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a hook brick structure, which can eliminate the hidden danger that the supporting iron plate is easily burned and has high safety.

[0004] The present invention also provides a glass melting furnace having the above hook brick structure.

[0005] The hook brick structure according to the first embodiment of the present invention comprises:

[0006] pool wall;

[0007] A column, arranged on the outer side of the pool wall;

[0008] An iron supporting plate is installed on the column, and the upper surface of the iron supporting plate is lower than the upper surface of the pool wall;

[0009] The hook brick body comprises a brick body and a hook head, wherein the brick body is arranged on the upper surface of the supporting iron plate, and the hook head is arranged at one end of the brick body close to the pool wall, the hook head is higher than the lower surface of the brick body, and the hook head extends to the upper side of the pool wall and is connected to the pool wall;

[0011] The hook brick structure according to the embodiment of the present invention has at least the following beneficial effects:

[0012] The iron support plate in the traditional structure is installed at a position 90mm to mm higher than the pool wall, which is optimized so that the upper surface of the iron support plate is lower than the upper surface of the pool wall, and the hook head protruding downward from the brick body in the traditional structure is optimized so that the hook head is higher than the lower surface of the brick body. This ensures that when the pool wall is eroded in the later stage of the melting furnace, the iron support plate will not be exposed to the high-temperature molten glass, and when the hook head breaks during the operation of the melting furnace, the iron support plate will not be exposed to the flame space. This can eliminate the hidden danger of high-temperature molten glass and flame directly burning the iron support plate, thereby ensuring the safety of the melting furnace operation throughout the entire kiln period.

[0015] According to some embodiments of the present invention, an arc transition surface is provided at the upper end of the hook head, and the arc transition surface extends to the edge of the upper surface of the brick body.

[0016] According to some embodiments of the present invention, the column is provided with a limiting structure, and the limiting structure abuts downward against the brick body.

[0017] According to some embodiments of the present invention, the upper surface of the brick body is recessed to form a step at an 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 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, a limiting surface is provided at the lower end of the hook head, 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 overlaps 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 portion is configured as a seam-blocking brick, and an abutment surface is vertically provided at one end of the hook head away from the brick body, and the abutment surface is in contact with the side wall of the seam-blocking brick.

[0021] The glass melting furnace according to the second embodiment of the present invention comprises the hook brick structure described in the first embodiment.

[0022] According to the glass melting furnace of the embodiment of the present invention, the iron support plate in the traditional structure is installed at a position 90mm to mm higher than the pool wall, which is optimized so that the upper surface of the iron support plate is lower than the upper surface of the pool wall, and the hook head protruding downward from the brick body in the traditional structure is optimized so that the hook head is higher than the lower surface of the brick body, thereby ensuring that when the pool wall is eroded in the later stage of the melting furnace, the iron support plate will not be exposed to the high-temperature molten glass, and when the hook head breaks during the operation of the melting furnace, the iron support plate will not be exposed to the flame space, which can eliminate the hidden danger of high-temperature molten glass and flame directly burning the iron support plate, and ensure the safety of the melting furnace operation during the entire kiln period.

[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] In the description of the present invention, "a plurality" means more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] In the existing structure, the iron support plate is installed at a position 90mm to 100mm higher than the pool wall. Since the iron support plate is higher than the pool wall, the hook head of the hook brick will protrude downward from the lower surface of the brick body. In the later stage of the melting furnace operation, the pool wall is eroded by the glass liquid and gradually becomes thinner (the pool wall needs to be tied with bricks for maintenance many times in the later stage of the melting furnace). The old pool wall is eroded and the iron support plate is exposed to the high-temperature glass liquid, burned and oxidized by the high-temperature glass liquid, and the strength of the steel structure is affected, which may seriously threaten the safety of the melting furnace. During the operation of the melting furnace, the hook head of the hook brick often breaks, which cannot protect the iron support plate. The iron support plate is directly exposed to the flame space, burned and carbonized, and its strength is affected, which may seriously threaten the safety of the melting furnace.

[0040] Therefore, the present invention proposes a hook brick structure and a glass melting furnace, which can effectively improve the above problems.

[0041] Refer to the following Figures 1 to 4 The hook brick structure and the glass melting furnace according to the embodiments of the present invention are described.

[0042] The hook brick structure according to the first embodiment of the present invention comprises: a pool wall 100, a column 200, a supporting iron plate 300, a hook brick body 400, and a breast wall 500. It should be noted that in the later stage of the melting furnace, the pool wall 100 is corroded by the high-temperature glass liquid, and new bricks 120 need to be attached to the outer side of the pool wall 100 for maintenance.

[0043] For example, the pillars 200 are disposed on the outside of the pool wall 100 , and the inside of the pool wall 100 is high-temperature molten glass.

[0044] The iron support plate 300 is installed on the column 200, and the upper surface of the iron support plate 300 is lower than the upper surface of the pool wall 100. Obviously, the iron support plate 300 is located outside the pool wall 100. It should be noted that the upper surface of the iron support plate 300 and the upper surface of the pool wall 100 are both horizontal, and the iron support plate 300 and the column 200 are both steel structures.

[0045] The hook brick body 400 is an integrated structure, and the hook brick body 400 includes a brick body 401 and a hook head 402. The brick body 401 is arranged on the upper surface of the supporting iron 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 arranged at one end of the brick body 401 close to 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 is connected to the pool wall 100.

[0046] The breast wall 500 is built on the upper end of the brick body 401. The breast wall 500, the hook brick body 400 and the pool wall 100 separate the interior of the melting furnace from the exterior space.

[0047] The hook brick structure of the embodiment of the present invention optimizes the position of the iron support plate 300 relative to the pool wall 100 and the structure of the hook brick body 400. The traditional structure in which the iron support plate 300 is installed at a position 90mm to 100mm higher than the pool wall is optimized to have the upper surface of the iron support plate 300 lower than the upper surface of the pool wall 100, and the traditional structure in which the hook head 402 protrudes downward from the brick body 401 is optimized to have the hook head 402 higher than the lower surface of the brick body 401. This ensures that when the pool wall 100 is eroded in the later stage of the melting furnace, the iron support plate 300 will not be exposed to the high-temperature molten glass. When the hook head 402 breaks during the operation of the melting furnace, the iron support plate 300 will not be exposed to the flame space. This can eliminate the hidden danger of high-temperature molten glass and flame directly burning the iron support plate 300, thereby ensuring the safety of the melting furnace operation throughout the entire kiln period.

[0048] Reference Figure 1As shown, in some embodiments of the invention, the value range of the height difference h1 between the upper surface of the iron support plate 300 and the upper surface of the pool wall 100 is: 90mm≤h1≤120mm. It can be understood that in order to prevent the iron support plate 300 from being exposed to the high-temperature glass liquid or exposed to the flame space, the upper surface of the iron support plate 300 needs to be lower than the upper surface of the pool wall 100, and the height difference between the two is used to protect the iron support plate 300. However, if the height difference between the upper surface of the iron support plate 300 and the upper surface of the pool wall 100 is too small, the iron support plate 300 will be damaged. The protective effect of the plate 300 will be relatively poor. If the height difference between the upper surface of the iron supporting plate 300 and the upper surface of the pool wall 100 is too large, the space outside the pool wall 100 will be occupied, resulting in the pool wall 100 being eroded in the later stage of the melting furnace. The operating space for pasting new bricks 120 on the outside of the pool wall 100 becomes smaller. Therefore, the height difference between the upper surface of the iron supporting plate 300 and the upper surface of the pool wall 100 is preferably 90mm to 120mm. This can not only ensure a better protective effect on the iron supporting plate 300, but also avoid occupying the space for pasting 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, a slope 403 is provided at the lower end of the hook head 402. The slope 403 extends downwardly along a direction away from the pool wall 100 to the edge of the lower surface of the brick body 401. The inclined top of the slope 403 is higher than the upper surface of the pool wall 100. It can be understood that after the pool wall 100 is eroded in the later stage of the melting furnace, it is necessary to paste new bricks 120 on the outer surface of the pool wall 100 for maintenance. In order to provide more space for the operation of pasting new bricks 120, the present embodiment provides a slope 403 at the lower end of the hook head 402, so that the slope 403 extends downwardly to the edge of the lower surface of the brick body 401, so that the lower end of the hook head 402 and the lower surface of the brick body 401 are transitioned through the slope 403, thereby avoiding the new bricks 120. Obviously, since the lower surface of the brick body 401 is lower than the upper surface of the pool wall 100, if the lower end of the hook head 402 and the lower surface of the brick body 401 are transitioned through a vertical surface, the upper space reserved for the new brick 120 will become smaller. As a result, the number of layers of the new brick 120 that can be pasted 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 is lower than that of the pool wall 100. Once the top of the pool wall 100 is eroded by the glass liquid at a later stage, the glass liquid will be at risk of overflowing.

[0050] Reference Figure 2 As shown, in some embodiments of the invention, the upper end of the hook head 402 is provided with an arc transition surface 404, and the arc transition surface 404 extends to the upper surface edge of the brick body 401, that is, an arc transition is formed between the upper end of the hook head 402 and the brick body 401, thereby avoiding stress concentration and causing the hook head 402 to break, thereby extending 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 body 401 away from the hook head 402. The limiting structure 210 abuts downward against the brick body 401, thereby cooperating with the supporting iron plate 300 to vertically limit the brick body 401, thereby preventing the center of gravity of the hook brick body 400 and the breast wall 500 as a whole from being biased toward the pool wall 100, causing the breast wall 500 and the hook brick body 400 to tilt toward the pool wall 100, thereby improving the structural stability. In a further embodiment, a step 405 is provided on the upper surface of the brick body 401 at an end away from the hook head 402, and the limiting structure 210 abuts against the step 405 downward, thereby abutting against the brick body 401 downward. By providing the step 405, the installation of the limiting structure 210 can be facilitated. It can be understood that the breast wall 500 is built on the upper end of the brick body 401. In the process of building the breast wall 500, it is often impossible to accurately determine the position of the breast wall 500. In order to avoid the breast wall 500 occupying the installation space of the limiting structure 210, the step 405 is provided on the upper surface of the brick body 401 away from the hook head 402 in this embodiment. The limiting structure 210 abuts against the brick body 401 downward by abutting against the step 405 downward. In this way, when building the breast wall 500, it is only necessary to make the breast wall 500 avoid the upper side of the step 405 to avoid the breast wall 500 occupying 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 can be imagined 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 can allow the angle steel to have a certain installation error and allow the step 405 to have a certain processing error, and the influence of the above two errors can be eliminated by the pad.

[0052] Reference Figure 1 and Figure 2 As shown, in some embodiments of the invention, a sealing portion 110 is protruding from the upper surface of the pool wall 100, a gap is set 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 portion 110 to maintain the seal with the sealing portion 110. It can be imagined that the pool wall 100 is in contact with high-temperature glass liquid for a long time and is prone to expansion due to heat. If the hook head 402 directly abuts against the upper surface of the pool wall 100, the pool wall 100 will expand upward due to heat and squeeze the hook head 402, causing the hook head 402 to break. Therefore, in this embodiment, a gap is set 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, and the sealing between the hook head 402 and the pool wall 100 is achieved by the sealing portion 110 protruding from the upper surface of the pool wall 100.

[0053] Reference Figure 1 and Figure 2 As shown in Figure 2 , in some embodiments of the invention, a limiting surface 406 is provided at the lower end of the hook head 402. 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 coincides at least partially with the projection of the upper surface of the pool wall 100 on the horizontal plane. In this way, when the pool wall 100 expands due to heat, once the pool wall 100 expands to contact the hook head 402, the contact area between the pool wall 100 and the hook head 402 can be increased through the limiting surface 406, avoiding excessive stress concentration and reducing the risk of the hook head 402 breaking. It can be understood that both the limiting surface 406 of the hook head 402 and the lower surface of the brick body 401 are horizontal, and the value range of the height difference h2 between the limiting surface 406 of the hook head 402 and the lower surface of the brick body 401 is: 90mm < h2 ≤ 150mm, and h2 > h1, so as to leave a gap between the limiting surface 406 and the upper surface of the pool wall 100.

[0054] Referring to Figure 1 and Figure 2 As shown in Figure 2 , in some embodiments of the invention, the sealing portion 110 is provided as a joint-block brick. The joint-block brick is laid on the upper surface of the pool wall 100. An abutting surface 407 is vertically provided at one end of the hook head 402 away from the brick body 401. The abutting surface 407 fits against the side wall of the joint-block brick to maintain the seal between the hook head 402 and the joint-block brick. By providing the abutting surface 407 to fit against the side wall of the joint-block brick, the contact area is increased, the sealing effect is improved, and at the same time, the situation of excessive stress concentration can also be avoided.

[0055] In one specific embodiment, the hook brick structure includes: a tank wall 100, a column 200, a supporting iron plate 300, a hook brick body 400, and a breast wall 500. A joint-block is prominently provided on the upper surface of the tank wall 100; the column 200 is arranged on the outer side of the tank wall 100, and a limiting structure 210 is provided on the column 200, and the limiting structure 210 includes an angle steel; the supporting iron plate 300 is installed on the side of the column 200 close to the tank wall 100, the upper surface of the supporting iron plate 300 is horizontal, and the upper surface of the supporting iron plate 300 is lower than the upper surface of the tank wall 100, and the numerical range of the height difference h1 between the upper surface of the supporting iron plate 300 and the upper surface of the tank wall 100 is: 90mm ≤ h1 ≤ 120mm; the hook brick body 400 is an integral structure, and the hook brick body 400 includes a brick body 401 and a hook head 402. The brick body 401 is arranged on the upper surface of the supporting iron plate 300, and a step 405 is concavely provided at one end of the upper surface of the brick body 401 away from the hook head 402, and the angle steel abuts against the step 405 downward to abut against the brick body 401 downward; the hook head 402 is arranged at one end of the brick body 401 close to the tank wall 100, the hook head 402 is higher than the lower surface of the brick body 401, the hook head 402 extends above the tank wall 100, a slope 403 and a limiting surface 406 are provided at the lower end of the hook head 402, an arc transition surface 404 is provided at the upper end of the hook head 402, and an abutting surface 407 is further provided on the hook head 402. Among them, the abutting surface 407 is vertically arranged at one end of the hook head 402 away from the brick body 401, and the abutting surface 407 fits against the side wall of the joint-block to maintain the seal between the hook head 402 and the joint-block. One end of the arc transition surface 404 extends to the upper end of the abutting surface 407, and the other end extends to the edge of the upper surface of the brick body 401. The limiting surface 406 extends horizontally outward from the lower end of the abutting surface 407 away from the joint-block, and the slope 403 extends from the end of the limiting surface 406 away from the joint-block to the edge of the lower surface of the brick body 401, and the slope 403 extends downward obliquely along the direction away from the limiting surface 406. The numerical range of the height difference h2 between the limiting surface 406 of the hook head 402 and the lower surface of the brick body 401 is: 90mm < h2 ≤ 150mm, and h2 > h1; the breast wall 500 is built on the upper surface of the brick body 401 and is arranged avoiding the upper part of the step 405.
