Description

Technical Field

[0001] This utility model relates to the field of photovoltaic kiln technology, and in particular to a device for fixing rolled lip bricks. Background Technology

[0002] The lip brick is used in the forming area of ​​the photovoltaic solar rolled glass production line. It works in conjunction with the rolling mill, the main equipment for rolling forming. Its front end is tightly connected to the outer tail brick of the furnace overflow port. After the molten glass flows out of the furnace overflow port, it flows through the lip brick to the rolling mill, and high-quality photovoltaic rolled glass is produced by the rolling mill.

[0003] Lip bricks are one of the key pieces of equipment in the production process of photovoltaic rolled glass. They are used in the part before the forming rolling rollers of the rolled glass production line and come into direct contact with the molten glass. They have a direct impact on the yield of glass products. Lip bricks must have good thermal stability and good resistance to alkali corrosion. They must also have the performance advantages of short bubble removal time, long service life and high yield of glass products.

[0004] In existing kilns, the two ends of the lip brick are supported by a corbel, which is fixed to the ground. The lip brick inside the corbel is supported by the breast wall and end wall of the kiln overflow outlet. Due to the external force of glass traction and rolling during operation, coupled with the heating of different materials (breast wall brick and corbel) and the corrosion of the bricks, the lip brick is no longer supported by the breast wall brick and corbel after a period of use. This aggravates the loosening and corrosion of the connection, affecting the service life and rolling quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention proposes a fixing method that can improve the stability and reliability of lip bricks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a calendered lip brick fixing device, characterized in that it includes two support frames, two breast walls, an end wall, and a lip brick body. The two breast walls are respectively located inside the two support frames, the end wall is located between the two breast walls, and the lip brick body is located above the end wall. Both ends of the lip brick body extend above the support frames. The support frame includes a side baffle adapted to the end of the lip brick body and a base plate located at the bottom of the breast wall.

[0007] Furthermore, the lip brick body has through-tube cooling holes perpendicular to the side baffle, and the side baffle has positioning holes adapted to the through-tube cooling holes. The calendered lip brick fixing device includes cooling water pipes passing through the through-tube cooling holes and the positioning holes. The cooling water pipes circulate water to cool the lip brick body. At the same time, the cooling water pipes also serve as a connection between the lip brick body and the support frame to prevent loosening.

[0008] In this design, the support frame has a base plate, and the breast wall is stacked upwards on the base plate to form a stable support frame under longitudinal load. Compared with directly fixing the support to the ground, the support frame has better integration with the kiln brick components and a smaller temperature difference. In addition, due to the presence of side baffles and cooling water pipes, the stability between the lip brick body and the support frame is higher. The lip brick body extends beyond the breast wall and there are no gaps between it and the vertical surface of the breast wall, which improves the corrosion resistance of this area.

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 and Figure 3 As shown, it includes two support frames 1, two breast walls 2, end walls 3, and a lip brick body 4. The two breast walls 2 are located inside the two support frames 1 respectively, the end walls 3 are located between the two breast walls 2, and the lip brick body 4 is located above the end walls 3. Both ends of the lip brick body 4 extend above the support frames 1. The support frame 1 includes a side baffle 5 adapted to the end of the lip brick body 4 and a base plate 6 located at the bottom of the breast wall 2.

[0015] The lip brick body 4 has through-tube cooling holes perpendicular to the side baffle 5. The side baffle 5 has positioning holes adapted to the through-tube cooling holes. The calendered lip brick fixing device includes cooling water pipes 7 that pass through the through-tube cooling holes and positioning holes. The cooling water pipes 7 circulate water to cool the lip brick body 4. At the same time, the cooling water pipes 7 also serve as a connection between the lip brick body 4 and the support frame 1 to prevent loosening.

[0016] In this design, the support frame 1 has a base plate 6, and the breast wall 2 is stacked upward on the base plate 6 to form a stable support frame 1 under longitudinal load. Compared with directly fixing the support to the ground, the support frame 1 has better integration with the kiln brick components and a smaller temperature difference. In addition, due to the presence of the side baffle 5 and the cooling water pipe 7, the stability between the lip brick body 4 and the support frame 1 is higher. The lip brick body 4 extends beyond the breast wall 2 and there is no gap between it and the vertical surface of the breast wall 2, which improves the corrosion resistance of this area.

[0017] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
