Description

Technical Field

[0001] This application relates to the technical field of glass furnaces, and more specifically, to a glass furnace pool wall structure. Background Technology

[0002] Glass, as an inorganic non-metallic material, is one of the world's three pillar industries in materials science, and its current production technology relies heavily on key equipment—the glass furnace. Glass furnaces are used to melt the raw materials for various glass products. Currently, the furnace walls are paved with wall bricks. During operation, the molten glass and the wall bricks are in direct contact. The wall bricks near the arch are in contact with both the molten glass and air, forming a gas-liquid-solid three-phase interface.

[0003] Some existing glass furnaces (e.g., authorized publication number: CN 216191873U, titled: An Automatic Feeding Erosion-Resistant Glass Furnace) include a furnace body. The furnace body includes wall bricks, bottom bricks, and outer wall bricks. The wall bricks and bottom bricks are made of zirconium bricks. The outer wall bricks, made of corundum bricks, are installed on the outside of the wall bricks and bottom bricks. Multiple sets of heating electrodes are inserted horizontally and at equal intervals around the middle and lower part of the furnace body. The heating electrodes extend through the outer wall bricks and wall bricks into the interior of the melting pool. The wall bricks of the glass melt flow channel layer have horizontal annular holes inside. A blower is connected to the outside of the annular holes to maintain air circulation inside the annular holes, so as to cool the zirconium bricks and significantly reduce the temperature of the glass melt close to the zirconium bricks to a semi-solid state, thus slowing down the erosion of the wall bricks by the flow of the glass melt. Setting annular holes in the pool wall bricks can improve their corrosion resistance. However, since the pool wall bricks are of uniform size, the bricks located at the gas-liquid-solid three-phase interface are more severely corroded, creating a thickness difference with other pool wall bricks, which in turn affects the lifespan of the glass furnace. Utility Model Content

[0004] This application provides a glass furnace pool wall structure to solve the problem in the prior art where the pool wall bricks at the three-phase interface are too thin after erosion, thus shortening the service life of the glass furnace.

[0005] According to the present application, a glass furnace wall structure includes: a first pool wall brick, a second pool wall brick, a pool bottom brick, a first pool wall support brick, and a second pool wall support brick. The pool bottom brick is laid at the bottom of the melting pool, the second pool wall brick is located above the pool bottom brick, the first pool wall support brick and the second pool wall support brick are located between the pool bottom brick and the second pool wall brick, and there is a gap between the first pool wall support brick and the second pool wall support brick. The first pool wall brick is located above the second pool wall brick, and in its vertical projection, on the side closer to the melting pool, the first pool wall brick protrudes beyond the second pool wall brick.

[0006] In some embodiments, the side of the first pool wall brick closest to the melting pool is curved or flat.

[0007] In some embodiments, a plurality of second pool wall bricks are provided, which are laid along the height direction of the melting pool and, in the vertical projection, gradually protrude from bottom to top toward the direction of the melting pool.

[0008] In some embodiments, a plurality of second pool wall bricks are provided, which are laid along the height direction of the melting pool, and the sides of the plurality of second pool wall bricks near the melting pool are flush in the vertical projection.

[0009] In some embodiments, both the first pool wall bricks and the second pool wall bricks are made of high zirconium material.

[0010] In some embodiments, the bottom brick of the pool is recessed to form a first stepped surface and a second stepped surface, the first stepped surface and the second stepped surface are arranged perpendicularly, the lower surface of the second pool wall brick is arranged opposite to the first stepped surface, the first pool wall pad brick is installed on the first stepped surface, the second pool wall pad brick is partially installed on the first stepped surface, the first pool wall pad brick and the second pool wall pad brick are at the same height, and the side of the first pool wall pad brick away from the second pool wall pad brick is attached to the second stepped surface.

[0011] In some embodiments, the upper surfaces of the first pool wall pad bricks and the second pool wall pad bricks are both flush with the upper surface of the pool bottom bricks.

[0012] In some embodiments, the cross-section of the first pool wall pad brick in the horizontal direction is arranged in a "┍" shape. The first pool wall pad brick has a first plane, a second plane and a third plane. The first plane and the third plane are arranged in parallel, and the second plane and the first plane are arranged in perpendicular.

[0013] In some embodiments, the cross-section of the second pool wall pad brick in the horizontal direction is arranged in a "┛" shape. The second pool wall pad brick has a fourth plane, a fifth plane and a sixth plane. The fourth plane and the sixth plane are arranged in parallel, and the fifth plane and the fourth plane are arranged in perpendicular.

[0014] In some embodiments, the second plane and the fifth plane are abutted together, the first plane and the fourth plane are disposed opposite each other and have a gap distance, and the third plane and the sixth plane are disposed opposite each other and have a gap distance.

[0015] The glass furnace wall structure, applying the technical solution of this application, includes: a first pool wall brick, a second pool wall brick, a pool bottom brick, a first pool wall support brick, and a second pool wall support brick. The pool bottom brick is laid at the bottom of the melting pool, the second pool wall brick is located above the pool bottom brick, and the first and second pool wall support bricks are located between the pool bottom brick and the second pool wall brick, with a gap between them. This arrangement prevents the second pool wall brick and the pool bottom brick from opening due to thermal expansion. The first pool wall brick is located above the second pool wall brick, thus situated at the three-phase interface. In its vertical projection, the first pool wall brick protrudes beyond the second pool wall brick on the side closer to the melting pool. This arrangement provides dimensional compensation for the first pool wall brick compared to the second pool wall brick, preventing the glass furnace's lifespan from being affected by the insufficient thickness of the first pool wall brick during the etching process. The technical solution of this application effectively solves the problem in the prior art that the thickness of the pool wall bricks (i.e., the first pool wall bricks) located at the three-phase interface after erosion is too small, thus shortening the service life of the glass furnace.

[0025] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application.

The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] like Figure 1 and Figure 2 As shown, Embodiment 1 relates to a glass furnace wall structure, including: a first wall brick 10, a second wall brick 20, a bottom brick 30, a first wall support brick 40, and a second wall support brick 50. The bottom brick 30 is laid at the bottom of the melting pool 100, the second wall brick 20 is located above the bottom brick 30, the first wall support brick 40 and the second wall support brick 50 are located between the bottom brick 30 and the second wall brick 20, and there is a gap 60 between the first wall support brick 40 and the second wall support brick 50. The first wall brick 10 is located above the second wall brick 20, and in the vertical projection, it protrudes from the second wall brick 20 on the side closer to the melting pool 100.

[0028] The glass furnace wall structure, using the technical solution of this embodiment, includes: a first wall brick 10, a second wall brick 20, a bottom brick 30, a first wall support brick 40, and a second wall support brick 50. The bottom brick 30 is laid at the bottom of the melting pool 100, the second wall brick 20 is located above the bottom brick 30, and the first wall support brick 40 and the second wall support brick 50 are located between the bottom brick 30 and the second wall brick 20, with a gap 60 between them. This arrangement prevents the second wall brick 20 and the bottom brick 30 from opening due to thermal expansion. The first pool wall brick 10 is located above the second pool wall brick 20. Therefore, the first pool wall brick 10 is situated at the three-phase interface, and in its vertical projection, it protrudes beyond the second pool wall brick 20 on the side closest to the melting pool 100. This arrangement provides dimensional compensation for the first pool wall brick 10 compared to the second pool wall brick 20, thus preventing the glass furnace's lifespan from being affected by the insufficient thickness of the first pool wall brick 10 during the erosion process. The technical solution of this embodiment effectively solves the problem in the prior art where the thickness of the pool wall brick (i.e., the first pool wall brick 10) at the three-phase interface after erosion is less than the thickness of the pool wall bricks at other locations (i.e., the second pool wall brick 20), thereby shortening the glass furnace's lifespan.

[0029] It should be noted that both the first pool wall pad brick 40 and the second pool wall pad brick 50 are rectangular bricks. The glass furnace pool wall structure also includes outer wall bricks 70, which are laid on the outside of the first pool wall bricks 10 and the second pool wall bricks 20. After the first pool wall bricks 10, the second pool wall bricks 20 and the pool bottom bricks 30 are laid, the internal space forms a melting pool 100 for melting production raw materials.

[0030] In the technical solution of Embodiment 1, the side of the first pool wall brick 10 closest to the melting pool 100 is curved or flat. To improve the lifespan of the glass furnace, the first pool wall brick 10 is dimensionally compensated compared to the second pool wall brick 20. The side of the first pool wall brick 10 closest to the melting pool 100 is the side with the highest degree of erosion. Setting it as a curved surface can reduce the scouring of the molten glass with the corners, thereby slowing down the erosion.

[0031] like Figure 1 As shown, in the technical solution of Embodiment 1, multiple second pool wall bricks 20 are provided. These multiple second pool wall bricks 20 are laid along the height direction (i.e., the vertical direction) of the melting pool 100, and in the vertical projection, they gradually protrude from bottom to top towards the melting pool 100. The purpose of this arrangement is to make the first pool wall brick 10 and the multiple second pool wall bricks 20 form a stepped structure in sequence. When the glass melt content changes, the size of the position with the greatest degree of erosion is always larger than the size of the position with the lesser degree of erosion.

[0032] In the technical solution of Embodiment 1, both the first pool wall brick 10 and the second pool wall brick 20 are made of high zirconium material, with a ZrO2 content greater than 94% and a glass phase content of no more than 5%. This material selection ensures that the bricks do not undergo a solid solution reaction with the molten glass.

[0033] like Figure 2 As shown, in the technical solution of Embodiment 1, the bottom brick 30 is recessed to form a first stepped surface 31 and a second stepped surface 32. The first stepped surface 31 and the second stepped surface 32 are arranged vertically. The lower surface of the second pool wall brick 20 is arranged opposite to the first stepped surface 31. The first pool wall pad brick 40 is installed on the first stepped surface 31. The second pool wall pad brick 50 is partially installed on the first stepped surface 31. The first pool wall pad brick 40 and the second pool wall pad brick 50 have the same height. The side of the first pool wall pad brick 40 away from the second pool wall pad brick 50 is attached to the second stepped surface 32.

[0034] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the upper surfaces of the first pool wall pad brick 40 and the second pool wall pad brick 50 are both flush with the upper surface of the pool bottom brick 30. This arrangement ensures accurate positioning and convenient construction of the second pool wall brick 20 during installation.

[0035] like Figure 3 As shown, the difference between the technical solution of Embodiment 2 and Embodiment 1 is that multiple second pool wall bricks 20 are provided, and these multiple second pool wall bricks 20 are laid along the height direction (i.e., the vertical direction) of the melting pool 100. In the vertical projection, the sides of the multiple second pool wall bricks 20 near the melting pool 100 are flush. The first pool wall brick 10 is located at the three-phase interface, and the second pool wall brick 20 is in contact with the molten glass phase. Therefore, the erosion effect on the first pool wall brick 10 is greater than that on the second pool wall brick 20. In the vertical projection, on the side near the melting pool 100, the first pool wall brick 10 protrudes beyond the second pool wall brick 20, ensuring that the lifespan of the glass furnace is not affected by the insufficient thickness of the first pool wall brick 10 during the erosion process.

[0036] like Figure 4As shown, the difference between the technical solution of Embodiment 3 and Embodiment 1 is that the cross-section of the first pool wall pad 40 along the horizontal direction is arranged in a "┍" shape. The first pool wall pad 40 has a first plane 41, a second plane 42, and a third plane 43. The first plane 41 and the third plane 43 are arranged parallel to each other, and the second plane 42 is arranged perpendicular to the first plane 41. The cross-section of the second pool wall pad 50 along the horizontal direction is arranged in a "┛" shape. The second pool wall pad 50 has a fourth plane 51, a fifth plane 52, and a sixth plane 53. The fourth plane 51 and the sixth plane 53 are arranged parallel to each other, and the fifth plane 52 is arranged perpendicular to the fourth plane 51. The second plane 42 and the fifth plane 52 are in contact with each other, the first plane 41 and the fourth plane 51 are arranged opposite each other with a gap, and the third plane 43 and the sixth plane 53 are arranged opposite each other with a gap. By setting the interval distance, it is possible to prevent the second pool wall brick 20 and the pool bottom brick 30 from cracking due to heat. The second plane 42 and the fifth plane 52 are in contact, which can prevent the glass liquid from flowing out between the first plane 41 and the fourth plane 51 and between the third plane 43 and the sixth plane 53.
