Abstract
Description
Technical Field
[0001] This application relates to the technical field of glass kilns, and in particular to a novel arch brick structure. Background Technology
[0002] Currently, during the construction of kilns, sufficient gaps need to be reserved between the top of the breast wall and the arch bricks. During the firing process, as the temperature rises, the breast wall and arch bricks will expand. Therefore, the gap between the top of the breast wall and the arch bricks provides space for the expansion of the breast wall and arch bricks.
[0003] However, during kiln firing, this gap will leak smoke and fire. Usually, it is temporarily plugged with refractory cotton in advance to prevent smoke leakage. However, as the temperature rises, the refractory cotton will harden and fall off. Once smoke and fire leak, it will cause damage and danger to the external steel structure. Due to the high temperature and limited operating space, it is also difficult to deal with smoke and fire leakage. Even if it is dealt with, there is still a risk of smoke and fire leakage again. Utility Model Content
[0004] In order to reduce the probability of smoke and fire leakage during kiln firing due to the gap between the top of the breast wall and the arch bricks, this application provides a novel arch brick structure.
[0005] This application provides a novel arch foot brick structure, which adopts the following technical solution:
[0006] A novel arch brick structure includes a breast wall, a sliding block, a top wall, arch bricks, and a fixing mechanism. The breast wall is set on the ground, the arch bricks are set on the ground by the fixing mechanism, the top wall is set on the arch bricks, the sliding block is set on the end face of the breast wall near the arch bricks, the end face of the sliding block near the arch bricks has a first groove, the end face of the arch bricks near the breast wall has a second groove, and the connection between the first groove and the second groove forms a vertical slit.
[0007] By adopting the above technical solution, when the kiln is being fired, both the sliding block and the arch brick expand. The expanded arch brick and sliding block seal the vertical joints, thereby reducing the probability of smoke and fire leakage during the firing process.
[0008] Optionally, ceramic fiber paper is inserted into the first groove.
[0009] By adopting the above technical solution, the ceramic fiber paper has high temperature resistance and elasticity during the kiln firing process, which not only blocks the leakage of flue gas, but also does not affect the upward expansion of the breast wall.
[0010] Optionally, the fixing mechanism includes two support frames, a crossbeam, a channel steel, and an adjustment component. Both support frames are set on the ground, and the ends of both support frames away from the ground are connected to the crossbeam. The channel steel is set on the support frames through the adjustment component and connected to the arch brick.
[0011] By adopting the above technical solution, the support frame and channel steel are installed to fix the arch foot bricks, thereby fixing the top wall.
[0012] Optionally, the adjusting assembly includes an adjusting bolt and a connecting block. The adjusting bolt is threaded onto the support frame, and the connecting block is disposed on the side wall of the channel steel away from the arch foot brick. The connecting block is rotatably connected to the adjusting bolt.
[0013] By adopting the above technical solution, the adjustment of the channel steel is achieved by adjusting the bolts and connecting blocks, thereby realizing the lateral adjustment of the arch bricks and ensuring the thermal expansion space of the arch bricks.
[0014] Optionally, the sliding block limiting mechanism includes a limiting rod and a power assembly. The power assembly is mounted on the support frame, and the limiting rod is mounted on the power assembly and abuts against the sliding block.
[0015] By adopting the above technical solution, the setting of the limiting rod limits the sliding block, thereby causing the sliding block to expand away from the limiting rod during kiln firing, thus sealing the vertical seam and reducing the probability that the sliding block's expansion is not directional and therefore cannot seal the vertical seam.
[0016] Optionally, the power assembly includes a first mounting plate and a hydraulic cylinder. The first mounting plate is disposed on the support frame, and the hydraulic cylinder is disposed on the first mounting plate. The piston shaft of the hydraulic cylinder is connected to the limiting rod.
[0017] By adopting the above technical solution, when the width of the vertical seam is adjusted, the hydraulic cylinder is activated, the hydraulic cylinder drives the limit rod to move, the limit rod drives the sliding block to move, thereby realizing the adjustment of the width of the vertical seam and leaving room for the thermal expansion of the sliding block.
[0018] Optionally, an arch brick limiting mechanism is provided on the top wall. The arch brick limiting mechanism includes a limiting block and an installation component. The limiting block is set on the top wall through the installation component, and the limiting block abuts against one end of the arch brick located inside the kiln.
[0019] By adopting the above technical solution, the setting of the limiting block realizes the limiting of the arch brick, so that when the kiln is fired, the expansion of the arch brick is directed away from the limiting block, thereby sealing the vertical joint and reducing the probability that the arch brick cannot seal the vertical joint due to its non-directional expansion.
[0020] Optionally, the mounting assembly includes a connecting plate, a second mounting plate, and a fixing bolt. The connecting plate is disposed on the top wall and connected to the limiting block. The second mounting plate is disposed on the connecting plate, and the fixing bolt passes through the second mounting plate and is threaded onto the top wall.
[0021] By adopting the above technical solution, the installation of the limit block is achieved by setting up the connecting plate, the second mounting plate, and the fixing bolts.
[0022] In summary, this application includes the following beneficial technical effects:
[0023] 1. When the kiln is being fired, both the sliding block and the arch bricks expand. The expanded arch bricks and sliding blocks seal the vertical joints, thereby reducing the probability of smoke and fire leakage during the firing process.
[0024] 2. During the kiln firing process, the ceramic fiber paper is heat-resistant and elastic, which not only blocks the leakage of flue gas, but also does not affect the upward expansion of the breast wall;
[0025] 3. The setting of the limiting rod limits the sliding block, which in turn causes the sliding block to expand away from the limiting rod during kiln firing, thereby sealing the vertical seam and reducing the probability that the sliding block's expansion is not directional and thus fails to seal the vertical seam.

Detailed Implementation
[0032] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0033] This application discloses a novel arch brick structure. Example
[0034] refer to Figure 1 and Figure 2 The novel arch brick 300 structure includes a breast wall 100, which is set on the ground. A sliding block 400 is slidably connected to the end of the breast wall 100 away from the ground. A fixing mechanism 600 is also set on the ground. Two arch bricks 300 are set on the fixing mechanism 600. The ends of the two arch bricks 300 away from the breast wall 100 are fixedly connected to a top wall 200. A first groove 310 is opened on the end face of the sliding block 400 near the arch brick 300. A second groove 410 is opened on the end of the arch brick 300 away from the top wall 200. A vertical slit 420 is formed at the connection between the first groove 310 and the second groove 410. Ceramic fiber paper 500 is inserted into the first groove 310.
[0035] refer to Figure 3 The fixing mechanism 600 includes multiple support frames 610, which are divided into two groups. Both groups of support frames 610 are fixedly connected to the ground and are symmetrically arranged about the top wall 200. The ends of the two support frames 610 symmetrically arranged about the top wall 200 that are away from the ground are connected together to a crossbeam 620. The fixing mechanism 600 also includes an adjusting component 640, which includes multiple adjusting bolts 641. The multiple adjusting bolts 641 are threadedly connected to the multiple support frames 610, and each support frame 610 is threadedly connected to two adjusting bolts 641. The ends of the multiple adjusting bolts 641 located on the same side that are close to the arch brick 300 are connected to a channel steel 630. Multiple connecting blocks 642 are fixedly connected to the side wall of the channel steel 630 that is away from the arch brick 300. The multiple connecting blocks 642 are rotatably connected to the multiple adjusting bolts 641 respectively.
[0036] The channel steel 630 is used to fix the arch foot brick 300, which in turn fixes the top wall 200; at the same time, the adjusting bolt 641 is used to adjust the channel steel 630, which facilitates the lateral adjustment of the arch foot brick 300, and thus the adjustment of the width of the vertical joint 420, ensuring sufficient expansion gap.
[0037] The implementation principle of Embodiment 1 of this application is as follows: When the kiln is being fired, both the sliding block 400 and the arch brick 300 expand. The first groove 310 and the second groove 410 provide space for the expansion of the sliding block 400 and the arch brick 300. At the same time, the expanded arch brick 300 and the sliding block 400 seal the vertical joint 420, thereby reducing the probability of smoke and fire leakage during the kiln firing. Example
[0038] refer to Figure 4 The difference between this embodiment and embodiment 1 is that a sliding block limiting mechanism 700 is also provided on the support frame 610. The sliding block limiting mechanism 700 includes a power component 720, which includes multiple first mounting plates 721. The multiple first mounting plates 721 are respectively fixedly connected between two adjacent support frames 610. A hydraulic cylinder 722 is fixedly connected to the end face of the first mounting plate 721 away from the ground. A limiting rod 710 is fixedly connected to the piston shaft of the multiple hydraulic cylinders 722 located on the same side. The limiting rod 710 abuts against the sliding block 400.
[0039] The limiting rod 710 limits the sliding block 400, thereby causing the sliding block 400 to expand away from the limiting rod 710 during kiln firing, thus sealing the vertical seam 420 and reducing the probability that the sliding block 400's expansion is not directional and therefore cannot seal the vertical seam 420. At the same time, when the width of the vertical seam 420 is adjusted, the hydraulic cylinder 722 is activated, which drives the limiting rod 710 to move, and the limiting rod 710 drives the sliding block 400 to move, thereby realizing the adjustment of the width of the vertical seam 420 and leaving room for the thermal expansion of the sliding block 400.
[0040] refer to Figure 5An arch brick limiting mechanism 800 is provided on the top wall 200. The arch brick limiting mechanism 800 includes an installation component 820, which includes an inner connecting plate 823. The connecting plate 823 is fixedly connected to one end of the top wall 200 located inside the kiln. A second mounting plate 821 is fixedly connected to the end of the connecting plate 823 near the top wall 200. The installation component 820 also includes multiple fixing bolts 822, all of which pass through the second mounting plate 821 and are threaded onto the top wall 200. A limiting block 810 is fixedly connected to the end face of the connecting plate 823 near the arch brick 300. The limiting block 810 abuts against the arch brick 300 and limits the arch brick 300. The setting of the limiting block 810 realizes the limitation of the arch brick 300, so that when the kiln is fired, the expansion of the arch brick 300 expands away from the limiting block 810, thereby sealing the vertical joint 420 and reducing the probability that the arch brick 300 cannot seal the vertical joint 420 due to non-directional expansion.
[0041] The implementation principle of Embodiment 2 of this application is as follows: The setting of the limiting rod 710 and the limiting block 810 respectively realizes the limiting of the sliding block 400 and the arch brick 300, thereby causing the sliding block 400 and the arch brick 300 to move towards the position of the vertical joint 420 when they are heated and expanded, thus sealing the vertical joint 420. This reduces the probability that the non-directional expansion of the sliding block 400 and the arch brick 300 when they are heated will prevent the vertical joint 420 from being sealed.
[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
