Description

Technical Field

[0001] This utility model belongs to the field of glass kiln technology, and more specifically, it relates to a structure of a flame-blocking brick for the overflow outlet of a glass kiln. Background Technology

[0002] Kiln baffle bricks operate under high temperatures daily. Significant temperature fluctuations occur when changing calenders or lip bricks, leading to cracks over time. These cracks, influenced by their own weight, continue to change temperature and eventually break off, falling into the overflow glass molten glass. During normal production, it is difficult to remove them from the molten glass, necessitating replacement of the calender and resulting in substantial economic losses. Furthermore, oxides accumulate on the outer surface of the baffle bricks during production. Over time, these oxides fall into the overflow glass molten glass, damaging the calender rolls and disrupting normal production.

[0003] Existing technology includes a structure entitled "Arrangement Structure of Flame-Blocking Bricks for a Substrate Glass Furnace" (application number CN201921645051.4). This technology provides an arrangement structure for flame-blocking bricks in a substrate glass furnace, comprising a breast wall, flame-blocking bricks, and a breast wall support. The flame-blocking bricks are disposed on the upper surface of the furnace wall. The cross-sections of the flame-blocking bricks and the breast wall support are L-shaped. The breast wall support is fixed above the flame-blocking bricks, and the horizontal section of the breast wall support is vertically attached to the inner side of the vertical section of the flame-blocking bricks. The lower end of the breast wall is attached to the breast wall. The upper surface of the horizontal section of the support iron, and the two walls of the breast wall are respectively attached to the inner side of the vertical section of the flame-deflecting brick and the inner side of the vertical section of the support iron. A gap is left between the breast wall and the inner side of the vertical section of the flame-deflecting brick. When the breast wall and the flame-deflecting brick are heated and expanded, the breast wall and the flame-deflecting brick are sealed. A gap is left between the upper surface of the support iron and the flame-deflecting brick in the horizontal direction. This effectively solves the problem of interference and jamming between the flame-deflecting brick and the support iron due to expansion during the heating process of the substrate glass furnace, and can further improve the corrosion resistance of the flame-deflecting brick.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a glass furnace overflow outlet flame baffle structure that is simple in structure, can prevent broken flame baffle bricks from falling into the molten glass, and at the same time prevent oxides on the outer surface of the flame baffle bricks from falling into the molten glass, in order to address the shortcomings of the existing technology.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model relates to a structure for a flame-blocking brick at the overflow outlet of a glass kiln, comprising multiple flame-blocking bricks. The upper part of the flame-blocking brick is clamped in the clamping groove of a clamping member, and the lower side of the flame-blocking brick is provided with an outwardly protruding ash trough. The flame-blocking brick is provided with through holes, and a positioning rod passes through the through holes of multiple flame-blocking bricks.

[0008] The flame-blocking brick is provided with an inverted trapezoidal clamping end on its upper part, and the clamping groove of the clamping member is configured as an inverted trapezoidal structure.

[0009] The flame-blocking brick has a through hole near its lower end.

[0010] The flame-blocking brick is provided with an ash trough near its lower side.

[0011] A lifting rod is provided on the connecting seat at the upper part of the clamping member.

[0012] The lifting rod is connected to the upper end of the fixing rod, and the positioning rod is connected to the lower end of the fixing rod.

[0013] When the upper part of the flame-blocking brick is clamped in the clamping groove of the clamping member, adjacent flame-blocking bricks are attached together, and the centers of the through holes of the flame-blocking bricks coincide.

[0014] When the upper part of the flame-blocking brick is clamped in the clamping groove of the clamping member, the adjacent ash dropping grooves are attached together, and the outer end of the ash dropping groove is provided with an upper protruding edge.

[0015] The flame-blocking brick has a forward protrusion extending from top to bottom on its front side and a rear concave portion extending from top to bottom on its rear side.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The overflow outlet flame-blocking brick structure of this utility model for glass furnaces involves the fabrication of multiple flame-blocking bricks. An outward-protruding ash-collecting groove is provided on the lower side of each flame-blocking brick, located below the surface of the brick. This effectively catches falling oxides, preventing them from entering the molten glass. During arrangement, the upper part of each flame-blocking brick is clamped in a clamping groove, ensuring reliable hoisting of each brick. Adjacent flame-blocking bricks are arranged close together, with their through holes overlapping. A positioning rod passes through multiple through holes, connecting and limiting the position of multiple flame-blocking bricks. Even if a single flame-blocking brick breaks, it will not fall into the molten glass due to the constraint at the bottom, thus not affecting normal production. This significantly reduces the risk of needing to replace the rolling mill and the occurrence of production anomalies. Furthermore, reducing the frequency of flame-blocking brick replacement also lowers resource consumption and waste emissions, meeting the requirements of green environmental protection and cost reduction.

[0024] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0025] As attached Figure 1 -Appendix Figure 4As shown, this utility model is a structure for a flame-blocking brick at the overflow outlet of a glass furnace, comprising multiple flame-blocking bricks 1. The upper part of the flame-blocking brick 1 is clamped in the clamping groove 3 of the clamping member 2. An outwardly protruding ash-collecting groove 4 is provided on the lower side of the flame-blocking brick 1. Through holes 5 are provided on the flame-blocking brick 1, and a positioning rod 6 passes through the through holes 5 of the multiple flame-blocking bricks 1. The above structure addresses the shortcomings of the prior art by proposing an improved technical solution. In the structure setting, multiple flame-blocking bricks 1 are manufactured separately, and the structure of the flame-blocking brick 1 is improved by providing an outwardly protruding ash-collecting groove 4 on the lower side of the flame-blocking brick 1. The ash-collecting groove 4 is located below the surface of the flame-blocking brick formed on the side of the flame-blocking brick 1, which can effectively catch the falling oxides and prevent oxides from entering the molten glass. When the flame deflector bricks 1 are arranged, the upper part of each flame deflector brick 1 is clamped in the clamping groove 3 of the clamping member 2, ensuring reliable hoisting of each flame deflector brick 1. Adjacent flame deflector bricks 1 are arranged close together, with the through holes 5 of the flame deflector bricks 1 overlapping. The positioning rod 6 passes through multiple through holes 5, thus connecting and limiting multiple flame deflector bricks. Even if a flame deflector brick 1 breaks, it will not fall into the molten glass because its lower part is constrained, thus not affecting normal production. This greatly reduces the risk of replacing the rolling mill and production abnormalities. At the same time, reducing the replacement frequency of the flame deflector bricks 1 also reduces resource consumption and waste emissions, meeting the requirements of green environmental protection and cost reduction and efficiency improvement. The flame deflector brick structure at the overflow port of the glass furnace described in this utility model is simple in structure and can prevent broken flame deflector bricks from falling into the molten glass, while also preventing oxides on the outer surface of the flame deflector bricks from falling into the molten glass.

[0026] The flame-blocking brick 1 has an inverted trapezoidal clamping end 13 on its upper part, and the clamping groove 3 of the clamping member 2 is also an inverted trapezoidal structure. With the above structure, the clamping end 13 and the clamping groove 3 cooperate to reliably clamp the upper part of the flame-blocking brick 1 in the clamping groove 3, thereby achieving reliable hoisting and arrangement of the flame-blocking brick 1.

[0027] The flame deflector brick 1 has a through hole 5 near its lower end. In the above structure, the through hole 5 is located near the lower part of the flame deflector brick 1, and the through hole 5 penetrates the flame deflector brick 1 to facilitate the passage of the positioning rod 6.

[0028] The flame-blocking brick 1 has an ash-collecting trough 4 located near its lower side. When the upper part of the flame-blocking brick 1 is clamped in the clamping groove 3 of the clamping member 2, adjacent ash-collecting troughs 4 are fitted together, and the outer end of the ash-collecting trough 4 is provided with an upper protruding edge 10. With this structure, the ash-collecting trough 4 effectively catches falling oxides, preventing oxides from falling into the molten glass. When the glass furnace stops operating, operators can clean the oxides on the flame-blocking brick on-site to prevent excessive oxide spillage.

[0029] A lifting rod 8 is installed on the connecting seat 7 on the upper part of the clamping member 2. The end of the lifting rod 8 is connected to the upper end of the fixing rod 9, and the end of the positioning rod 6 is connected to the lower end of the fixing rod 9. With the above structure, the lifting rod 8 is reliably connected to the connecting seat 7, and the lifting rod 8 is reliably arranged on site by being hooked by multiple hooks, so as to realize the reliable placement of the flame-blocking bricks in the corresponding positions at the glass kiln operation site.

[0030] When the upper part of the flame deflector brick 1 is clamped in the clamping groove 3 of the clamping member 2, adjacent flame deflector bricks 1 are in contact with each other, and the centers of the through holes 5 of the flame deflector bricks 1 coincide. In the above structure, the through holes 5 of the flame deflector bricks 1 have the same diameter and coincident centers, which facilitates the reliable passage of the fixing rod to achieve connection and limitation.

[0031] The flame deflector brick 1 has a forward protrusion 11 extending from top to bottom on its front side and a rear concave portion 12 extending from top to bottom on its rear side. In this structure, when adjacent flame deflector bricks 1 are attached together, the forward protrusion 11 of one flame deflector brick 1 and the rear concave portion 12 of the other flame deflector brick 1 are in a concave-convex fit.

[0032] The overflow baffle brick structure of the glass furnace described in this utility model involves the fabrication of multiple baffle bricks 1. The structure of the baffle bricks 1 is improved by incorporating an outwardly protruding ash-collecting groove 4 on the lower side of each baffle brick 1. This ash-collecting groove 4 is located below the surface of the baffle brick 1, effectively catching falling oxides and preventing them from entering the molten glass. When arranging the baffle bricks 1, the upper part of each baffle brick 1 is clamped within the clamping groove 3 of the clamping member 2, ensuring reliable hoisting of each baffle brick 1. Adjacent baffle bricks 1 are arranged close together, with their through holes 5 overlapping. A positioning rod 6 passes through multiple through holes 5, connecting and limiting the multiple baffle bricks. Even if a baffle brick 1 breaks, it will not fall into the molten glass due to the constraint at the bottom, thus not affecting normal production. This significantly reduces the risk of needing to replace the rolling mill and the occurrence of production abnormalities. At the same time, reducing the replacement frequency of the flame-blocking brick 1 also reduces resource consumption and waste emissions, which meets the requirements of green environmental protection and cost reduction and efficiency improvement.
