Technical Field

[0001] The utility model belongs to the technical field of glass production equipment, and specifically relates to a glass kiln lip brick. Background Art

[0002] The global solar photovoltaic market is developing rapidly. In order to meet the needs of industry development and further improve the efficiency of photovoltaic ultra-white rolled glass production, we can only continuously break through existing technologies.

[0003] Lip bricks are one of the most important molding parts in the production of photovoltaic ultra-clear glass and are mainly used in the molding part of glass kilns. The selection of lip brick materials and the installation process directly determine the output and quality of the produced glass.

[0004] The existing glass kiln lip bricks are made of sillimanite lip bricks, corundum lip bricks and zirconium mullite lip bricks, which are generally jade lip bricks. These lip bricks are made of refractory jade materials with low expansion coefficient and low porosity, and have the following disadvantages:

[0005] 1. The stone lip brick is made of jade. It will break if it is bumped during installation, which will affect its service life;

[0006] 2. The lip brick made of jade has a high water absorption rate, which will lead to a decrease in the quality of the finished glass during production;

[0007] 3. Stone lip bricks are prone to deformation in high temperature environments, affecting the stability of glass molding;

[0008] 4. Some stone lip bricks cannot withstand the erosion of molten glass, resulting in a reduced service life and increased replacement frequency at the production site.

[0009] For example, the patent document with the publication number CN116750950A discloses a glass kiln lip brick. The lip brick is located between the overflow port of the kiln and the calendering roller. The main body of the lip brick is a brick body, which is arranged parallel to the calendering roller. The brick body is provided with: a bottom surface, an overflow port surface, an outer end surface, and a side arc surface; an upper end surface located on the upper surface of the brick body, the surface of the upper end surface smoothly increases from the two outer end surfaces of the brick body to the middle of the brick body, and reaches the highest point in the middle of the brick body; a transition portion, located between the side arc surface and the upper end surface for transition; in the direction from the overflow port surface to the transition portion, all points on the upper end surface at the same distance from the same outer end surface have the same height. The technical solution disclosed in this patent document also cannot solve the technical problems described above. Utility Model Content

[0030] like Figures 1 to 7 As shown, the utility model provides a glass furnace lip brick, including a lip brick body 1, the lip brick body 1 is made of MA956 alloy material, and an air gun 2 for spraying flame toward a first side wall of the lip brick body 1 is arranged inside the lip brick body 1.

[0031] Specifically, if Figure 6 and Figure 7 As shown, a flame outlet 6 is provided on the air gun 2, a plurality of flame outlets 6 are provided and all flame outlets 6 are arranged in sequence along the length direction of the air gun 2, the flame outlet 6 and the first side wall are arranged opposite to each other, the length direction of the air gun 2 is parallel to the length direction of the lip brick body 1, the lip brick body 1 is an internally hollow structure, and the air gun 2 passes through the inner cavity of the lip brick body 1.

[0032] like Figure 6 and Figure 7 As shown, the air gun 2 is connected to an air inlet pipe, and multiple air inlet pipes are provided. Gas is transported to the inside of the air gun 2 through the air inlet pipes, and the air inlet pipes are connected to an external air source.

[0033] In this embodiment, if Figure 6 and Figure 7 As shown, three air inlet pipes are provided, namely a first air inlet pipe 3, a second air inlet pipe 4 and a third air inlet pipe 5. The first air inlet pipe 3 and the second air inlet pipe 4 are respectively connected to the opposite ends of the air gun 2, and the flame outlet 6 is distributed between the first air inlet pipe 3 and the second air inlet pipe 4. The third air inlet pipe 5 is located between the first air inlet pipe 3 and the second air inlet pipe 4. The third air inlet pipe 5 is connected to the air gun 2 at a position between the two ends of the air gun 2, so that the gas in the air gun 2 can be evenly distributed, ensuring that each flame outlet 6 can spray flames in time, so that the lip brick body 1 is heated evenly.

[0034] like Figures 6 to 8 As shown, the air gun 2 includes an outer sleeve 13 and an inner air pipe 12 disposed inside the outer sleeve 13, the inner air pipe 12 is connected to the first air inlet pipe 3, the second air inlet pipe 4 and the third air inlet pipe 5, the outer sleeve 13 and the inner air pipe 12 are both hollow structures and are coaxially arranged, the flame outlet 6 is arranged on the inner air pipe 12, and the inner air pipe 12 guides the gas from the air inlet pipe to the flame outlet 6. The inner diameter of the outer sleeve 13 is larger than the outer diameter of the inner air pipe 12, and a cooling channel for accommodating cooling water is formed between the outer sleeve 13 and the inner air pipe 12, and the two ends of the inner air pipe 12 are respectively connected to the water inlet pipe 7 and the water outlet pipe 8, and the water inlet pipe 7 and the water outlet pipe 8 extend to the outside of the outer sleeve 13, and the water inlet pipe 7 guides the cooling water into the outer tube body to cool the inner sleeve, and then discharges it through the water outlet pipe 8, so as to achieve effective control of the temperature of the air gun 2.

[0035] like Figures 1 to 3 As shown, the glass furnace lip brick of the utility model further includes a fixing seat 9 and a support plate 10, the support plate 10 is connected to the fixing seat 9, and the air gun 2 is arranged on the support plate 10. The fixing seat 9 is fixedly arranged at opposite ends of the lip brick body 1, and a support plate 10 is arranged on each fixing seat 9, and the two support plates 10 provide support for the air gun 2.

[0036] The first side wall of the lip brick body 1 is located at the top of the lip brick body 1. In the initial state, the first side wall is in an arc shape. The working surface 11 of the lip brick body 1 is slightly curved and presents a concave shape. The working surface 11 of the lip brick body 1 is the top surface of the first side wall. At this time, the heights of the two end parts of the working surface 11 in the length direction are greater than the height of the middle part of the working surface 11 in the length direction. The length direction of the working surface 11 is parallel to the length direction of the air gun 2. The specific bending degree of the first side wall refers to the metal material thermal bending curve diagram. When producing glass, after the air gun 2 sprays flames toward the first side wall, the lip brick is baked at high temperature by flame baking to thermally expand the first side wall. The working surface 11 will change from an arc surface to a plane parallel to the length direction of the air gun 2. After the working surface 11 reaches the required flatness, the molten glass can smoothly pass through the working surface 11.

[0037] Meanwhile, during the working process, the air gun 2 inside the lip brick can adjust the flatness of the working surface 11 of the lip brick in real time by adjusting the flow rate of the mixed combustible gas.

[0038] In the above structure, the working surface 11 of the lip brick body 1 is slightly curved, and the use effect is achieved by utilizing the principle of thermal expansion and contraction of the material; through the flame baking sprayed by the internal air gun 2, the flatness of the working surface 11 of the lip brick can be effectively and real-time adjusted to more efficiently meet the production and quality of the glass; at the same time, due to the particularity of the material of the lip brick body 1, there will be no problems such as damage and water absorption, and the lip brick body 1 can be used repeatedly.

[0039] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
