Description

Technical Field

[0001] The utility model relates to the technical field of glass kilns, in particular to a brick structure capable of measuring a silicon-rich layer of glass liquid in a kiln. Background Art

[0002] During glass production, the melting quality of the glass liquid is easily affected by fluctuations in the furnace state. When the furnace heats up, the glass batch materials will undergo a solid solution reaction between the oxides in the glass batch materials as the temperature rises. As the temperature continues to rise, the degree of reaction of the glass batch materials increases and the viscosity gradually decreases. When the viscosity of the glass batch materials decreases to a level with sufficient fluidity, it becomes a high-temperature glass liquid that can enter the channel and the molding area.

[0003] Publication No. CN216808570U discloses a checker brick masonry structure for a regenerator in a glass melting furnace. The structure is multi-layered, with each layer comprising a plurality of first brick bodies and second brick bodies. Both the first brick bodies and the second brick bodies are strip-shaped bricks. A first stepped groove is formed at each of two adjacent corners of the first brick body, and three first bosses are formed in the first brick body. A second stepped groove is formed at each of the four corners of the second brick body, and four second bosses are formed in the second brick body. In the middle of each layer of the masonry structure, the second bosses and the second stepped groove cooperate with each other, and the plurality of second brick bodies are arranged in a crisscross pattern. Around each layer of the masonry structure, the first stepped groove cooperates with the first and second bosses, respectively, to connect two adjacent second brick bodies.

[0004] The above technology uses bricks to build the walls of the kiln. Since the phase composition of the glass batch is often uneven during the melting process, the batch with lower density concentrates above the glass liquid, forming a silicon-rich layer of the glass liquid, and the glass batch with higher density concentrates at the bottom of the kiln pool, forming an aluminum-rich layer. Whether the silicon-rich layer or the aluminum-rich layer enters the channel, it will make the glass liquid difficult to clarify and reduce the product yield. Therefore, we propose a brick structure that can measure the silicon-rich layer of the kiln glass liquid. Utility Model Content

[0005] In response to the deficiencies in the prior art, the utility model provides a brick structure capable of measuring the silicon-rich layer in the glass liquid of a furnace. By inserting fused-cast magnesia bricks into the glass liquid and utilizing the reaction between magnesium in the fused-cast magnesia bricks and silicon or aluminum, the generation of forsterite and magnesia-aluminum spinel is detected. The distribution of the silicon-rich layer and the aluminum-rich layer in the glass liquid of the furnace can be known, thereby providing direction for the kiln process, making the kiln process optimization more efficient and refined, and reducing the operating costs of the production line.

[0006] In order to solve the above technical problems, the utility model solves the problem that it is inconvenient to measure the distribution of the silicon-rich layer and the aluminum-rich layer inside the kiln through the following technical solutions.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A brick structure capable of measuring the silicon-rich layer of the glass liquid in a furnace comprises a glass furnace pool bottom, a glass furnace pool wall fixedly provided on the top of the glass furnace pool bottom, a glass furnace crown fixedly provided on the top of the glass furnace pool wall, a glass furnace observation hole provided on the outer side of the glass furnace pool wall, a through hole provided on the glass furnace crown, a fused-cast magnesia brick capable of measuring the silicon-rich layer of the glass liquid in the furnace being embedded in the through hole, and a solid solution reaction zone one and a solid solution reaction zone two provided on the outer side of the fused-cast magnesia brick.

[0009] In some embodiments, the solid solution reaction zone 1 and the solid solution reaction zone 2 are vertically distributed one above and one below on the outside of the fused-cast magnesia brick, so that the silicon-rich layer and the aluminum-rich layer react in the solid solution reaction zone 1 and the solid solution reaction zone 2 respectively.

[0010] In some embodiments, evenly distributed protrusions are fixedly provided in the solid solution reaction zone one and the solid solution reaction zone two. The protrusions can serve as the starting point of crystal growth, i.e., the crystal nucleus, which reduces the energy barrier for crystal formation and makes it easier for the crystal to start growing at this position, thereby helping to form uniform, regular and high-quality crystals.

[0011] In some embodiments, a zirconium oxide coating is provided on the outside of the fused-cast magnesia bricks and the second solid solution reaction zone to prevent the fused-cast magnesia bricks outside the first and second solid solution reaction zones from reacting with silicon and aluminum in the molten glass.

[0012] In some embodiments, a metal block is fixed inside the fused-cast magnesia brick, and a cooling water pipe is fixed in the reserved hole inside the metal block to reduce the temperature in the solid solution reaction zone 1 and the solid-liquid reaction zone and increase the crystal generation rate.

[0013] In some embodiments, the cooling water pipe is U-shaped, and the cooling water inlet and outlet are both located above the metal block, which increases the residence time of the cooling water in the molten magnesia brick and facilitates the reflux of the cooling water.

[0014] In some embodiments, an extension plate is fixedly provided on one side of the metal block close to the solid solution reaction zone one and the solid solution reaction zone two. The extension plate is arranged in the fused-cast magnesia brick outside the solid solution reaction zone one and the solid solution reaction zone two. The extension plate is used to cover the solid solution reaction zone one and the solid solution reaction zone two, which facilitates the rapid transfer of heat in the solid solution reaction zone one and the solid solution reaction zone two to the metal block.

[0015] In some embodiments, the side of the molten magnesium brick away from the solid solution reaction zone one and the solid solution reaction zone two is in contact with the inner side of the glass furnace pool wall to prevent the glass liquid from entering the gap between the glass furnace pool wall and the molten magnesium brick, thereby preventing the formation of a thin surface of glass liquid in the gap and the subsequent cooling of the glass liquid thin surface into a solid.

[0016] In some embodiments, the extension piece and the metal block are integrally formed, and both the extension piece and the cooling water pipe are made of 316 heat-resistant steel, thereby improving the heat resistance of the extension piece, the metal block, and the cooling water pipe.

[0017] In some embodiments, the height of the protrusion is less than the depth of the solid solution reaction zone 1 and the solid solution reaction zone 2, so as to prevent crystals from growing out of the solid solution reaction zone 1 and the solid solution reaction zone 2, which makes it inconvenient to subsequently remove the fused-cast magnesia brick.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The utility model inserts fused magnesia bricks into the glass liquid, utilizes the reaction between magnesium in the fused magnesia bricks and silicon or aluminum, and detects the generation of forsterite and magnesia-aluminum spinel. The distribution of silicon-rich layer and aluminum-rich layer in the glass liquid of the kiln can be known, which provides direction for the kiln process, makes the kiln process optimization more efficient and refined, and reduces the operation cost of the production line.

[0020] By setting protrusions in the solid solution reaction zone 1 and the solid solution reaction zone 2 of the fused-cast magnesia brick, the protrusions can serve as the starting points for the growth of M2S (forsterite) crystals and MA crystals, i.e., crystal nuclei, which reduces the energy barrier for crystal formation and makes it easier for the crystals to start growing at this position, thus helping to form uniform, regular and high-quality crystals;

[0021] Fitting the outer side of the fused-cast magnesia brick to the inner side of the glass furnace pool wall can prevent the glass liquid from entering the gap between the glass furnace pool wall and the fused-cast magnesia brick to form a thin surface of glass liquid. The thin surface of glass liquid has a large heat dissipation area and is prone to cooling and solidification, sticking to the fused-cast magnesia brick and the glass furnace pool wall. Fitting the outer side of the fused-cast magnesia brick to the inner side of the glass furnace pool wall can avoid this situation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example:

[0036] See also Figure 1-Figure 7A brick structure capable of measuring the silicon-rich layer of furnace glass liquid comprises a glass furnace pool bottom 1, a glass furnace pool wall 2 is fixedly provided on the top of the glass furnace pool bottom 1, a glass furnace crown 3 is fixedly provided on the top of the glass furnace pool wall 2, a glass furnace observation hole 4 is provided on the outside of the glass furnace pool wall 2, a through hole 5 is opened on the glass furnace crown 3, a fused-cast magnesia brick 6 capable of measuring the silicon-rich layer of furnace glass liquid is embedded in the through hole 5, and a solid solution reaction zone 1 7 and a solid solution reaction zone 2 8 are provided on the outside of the fused-cast magnesia brick 6.

[0037] In an embodiment of the present application, the solid solution reaction zone 1 7 and the solid solution reaction zone 2 8 are vertically distributed one above and one below the other on the outside of the fused-cast magnesia brick 6, so that the silicon-rich layer and the aluminum-rich layer react in the solid solution reaction zone 1 7 and the solid solution reaction zone 2 8 respectively.

[0038] In the embodiment of the present application, a metal block 10 is fixed inside the molten magnesia brick 6, and a cooling water pipe 11 is fixed in the reserved hole inside the metal block 10 to reduce the temperature in the solid solution reaction zone 7 and the solid-liquid reaction zone and increase the crystal generation rate.

[0039] At the same time, the outer side of the fused-cast magnesia brick 6 excluding the solid solution reaction zone 1 7 and the solid solution reaction zone 2 8 is provided with a zirconium oxide coating to prevent the fused-cast magnesia brick 6 outside the solid solution reaction zone 1 7 and the solid solution reaction zone 2 8 from reacting with silicon and aluminum in the glass liquid.

[0040] During the implementation process, the bottom 1 of the glass furnace pool is placed on the bottom layer for carrying the glass liquid, the glass furnace pool wall 2 is used to build the glass furnace melting pool, and the glass furnace observation hole 4 can be installed with an endoscope to observe the combustion status of the furnace oxygen gun; the glass furnace top 3 makes the furnace a closed melting furnace, so that the high-temperature glass liquid is not contaminated by external impurities; when the defects of the glass liquid increase, in order to adjust the melting parameters of the glass liquid inside the furnace, first, the cast magnesium brick 6 that can measure the silicon-rich layer and the aluminum-rich layer of the furnace glass liquid is inserted into the high-temperature glass liquid, and the insertion position is selected in the slow flow area of ​​the glass liquid, on the left side of the glass furnace observation hole 4, between the two solid In the dissolution reaction zone, the SiO2 silicon dioxide in the silicon-rich area will react with the solid solution reaction zone 7 of the fused-cast magnesia brick 6 to generate high-melting-point M2Si (forsterite), and then precipitate M2Si crystals in situ. The Al2O3 alumina in the aluminum-rich area will react with the solid solution reaction zone 8 of the fused-cast magnesia brick 6 to generate high-melting-point MAl magnesium-aluminum spinel crystals that precipitate in situ. After being placed and allowed to stand for about a week, the crystals are taken out and the generation of M2Si and MAl is tested to know the distribution of silicon-rich and aluminum-rich layers in the kiln glass liquid, which provides direction for the kiln process, makes the kiln process optimization more efficient and refined, and reduces the production line operation cost.

[0041] By arranging uniformly distributed protrusions 9 in both the solution reaction zone 1 7 and the solution reaction zone 2 8, the protrusions 9 can serve as the starting point of crystal growth, i.e., the crystal nucleus, thereby reducing the energy barrier for crystal formation, making it easier for the crystal to start growing at this position, and contributing to the formation of uniform, regular and high-quality crystals. At the same time, an extension piece 12 covering the solution reaction zone 1 7 and the solution reaction zone 2 8 is arranged on the outside of the metal block 10 to transfer the heat inside the solution reaction zone 1 7 and the solution reaction zone 2 8 to the U-shaped cooling water pipe 11, and the heat is carried out by the cooling water, thereby reducing the temperature inside the solution reaction zone 1 7 and the solution reaction zone 2 8, increasing the crystal precipitation rate, and thus reducing the time required to collect the crystals.

[0042] At the same time, if Figure 7 As shown, the height of the protrusion 9 is less than the depth of the solid solution reaction zone 1 7 and the solid solution reaction zone 2 8, which can prevent crystals from growing out of the solid solution reaction zone 1 7 and the solid solution reaction zone 2 8, making it inconvenient to subsequently remove the fused-cast magnesia brick 6.

[0043] It is worth noting that the extension piece 12 and the metal block 10 are integrally formed, and both the extension piece 12 and the cooling water pipe 11 are made of 316 heat-resistant steel, thereby improving the heat resistance of the extension piece 12 , the metal block 10 , and the cooling water pipe 11 .

[0044] Fitting the outer side of the fused-cast magnesia brick 6 to the inner side of the glass furnace pool wall 2 can prevent the glass liquid from entering the gap between the glass furnace pool wall 2 and the fused-cast magnesia brick 6 to form a thin surface of glass liquid. The thin surface of the glass liquid has a large heat dissipation area and is prone to cooling and solidification, sticking to the fused-cast magnesia brick 6 and the glass furnace pool wall 2. Fitting the outer side of the fused-cast magnesia brick 6 to the inner side of the glass furnace pool wall 2 can avoid this situation.
