Description

Insulating brick structure and mixing tank Technical Field

[0001] This application relates to the technical field of glass processing, and more particularly to an insulating brick structure and a mixing tank. Background Technology

[0002] In the production of microcrystalline cover glass, the platinum channel stirring tank is one of the most important pieces of equipment. It plays a role in homogenizing the molten glass coming from the first cooling section and eliminating streaks.

[0003] A certain gap is left between the stirring rod and the cover brick to provide space for the stirring rod to rotate.

[0004] In existing technologies, the bottom of the insulating brick is flat, and the molten glass evaporates and condenses at the bottom of the insulating brick when heated. Because the temperature of the molten glass inside the mixing tank is very high, and there is convection between the moving stirring rod and the outside air, external contaminants can easily enter and crystallize upon contact with the condensed molten glass. These crystals accumulate to a certain extent and fall into the molten glass inside the mixing tank, causing contamination and affecting product yield, as shown in CN220265560U. Summary of the Invention

[0005] One of the technical problems this application aims to solve is that during the stirring of molten glass, there is a problem of crystallization falling into the molten glass, resulting in poor product quality.

[0006] To solve the above-mentioned technical problems, this application provides a thermal insulation brick structure and a mixing tank.

[0007] According to this application, a thermal insulation brick structure includes: a thermal insulation brick body, the thermal insulation brick body having a stirring hole, the thermal insulation brick body being disposed on a stirring barrel, the vertical projection of the stirring barrel being located inside the vertical projection of the thermal insulation brick body, the vertical projection of the stirring hole being located inside the vertical projection of the stirring barrel, the thermal insulation brick body also having a flow guiding surface, the flow guiding surface being located on the side of the thermal insulation brick body close to the stirring barrel, and the vertical height of the flow guiding surface continuously decreasing along the direction from close to to far away from the stirring hole.

[0008] In some embodiments, the main body of the insulating brick includes a first insulating brick and a second insulating brick. The first insulating brick includes a first guide section and a first connecting section. The first guide section is connected to the first connecting section and has a first arc-shaped inner surface. The second insulating brick includes a second guide section and a second connecting section. The second guide section is connected to the second connecting section and has a second arc-shaped inner surface. The first arc-shaped inner surface and the second arc-shaped inner surface together form a flow guiding surface.

[0009] In some embodiments, the first guide segment has multiple limiting protrusions and the second guide segment has multiple limiting grooves, with the multiple limiting protrusions and multiple limiting grooves being arranged in a one-to-one correspondence.

[0010] In some embodiments, the first guide segment has a first arcuate outer surface, which is parallel to the first arcuate inner surface, and the second guide segment has a second arcuate outer surface, which is parallel to the second arcuate inner surface.

[0011] In some embodiments, the projection of the inner surface of the first connecting section along the vertical direction is located outside the projection of the inner wall of the mixing tank along the vertical direction, and the projection of the inner surface of the second connecting section along the vertical direction is located outside the projection of the inner wall of the mixing tank along the vertical direction.

[0012] In some embodiments, the insulating brick structure further includes an operating part, which includes a first handle and a second handle. The first handle is connected to a first connecting section, and the second handle is connected to a second connecting section. Both the first connecting section and the second connecting section are fitted into the mixing tank.

[0013] In some embodiments, the main body of the insulating brick is made of alumina material.

[0014] In some embodiments, the operating part further includes a heat insulation part, which includes a plurality of heat insulation parts, and the plurality of heat insulation parts are respectively fitted onto the first handle and the second handle.

[0015] In some embodiments, the heat insulation is made of ceramic material.

[0016] In some embodiments, the mixing tank includes a mixing tank body and a stirring rod, with the heat-insulating brick body placed on the mixing tank body, and the stirring rod passing through the stirring hole and partially located inside the mixing tank body.

[0017] Through the above technical solution, the insulating brick structure provided in this application allows the glass inside the mixing tank to volatilize and move upwards under high temperature, condensing on the guide surface. Because the vertical height of the guide surface continuously decreases along the direction from near to far from the stirring hole, the condensed glass liquid moves away from the stirring hole, making it less susceptible to external low-temperature influences near the stirring hole and less likely to come into contact with impurities, thus preventing crystallization. The technical solution of this application effectively solves the problem in the prior art where crystals fall into the glass liquid during the stirring process, leading to poor product quality.

It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0032] As shown in Figures 1 to 4, the insulation brick structure disclosed in this application includes: an insulation brick body 10, the insulation brick body 10 having a stirring hole 11, the insulation brick body 10 being disposed on a stirring tank, the vertical projection of the stirring tank being located inside the vertical projection of the insulation brick body 10, the vertical projection of the stirring hole 11 being located inside the vertical projection of the stirring tank, the insulation brick body 10 also having a flow guiding surface 12, the flow guiding surface 12 being located on the side of the insulation brick body 10 close to the stirring tank, and the height of the flow guiding surface 12 in the vertical direction continuously decreasing along the direction from close to to far away from the stirring hole 11.

[0033] Using the heat-insulating brick structure disclosed in this application, the glass in the mixing tank evaporates and moves upward under high temperature, condensing on the guide surface 12. Since the vertical height of the guide surface 12 continuously decreases along the direction from near to far from the stirring hole 11, the condensed glass liquid moves away from the stirring hole 11, making it less susceptible to external low-temperature influences near the stirring hole 11 and less likely to come into contact with impurities, leading to crystallization. The technical solution of this embodiment effectively solves the problem in the prior art where crystals fall into the glass liquid during the stirring process, resulting in poor product quality.

[0034] As shown in Figures 1 to 4, in the technical solution of this embodiment, the main body 10 of the heat-insulating brick includes a first heat-insulating brick 13 and a second heat-insulating brick 14. The first heat-insulating brick 13 includes a first guide section 131 and a first connecting section 132. The first guide section 131 is connected to the first connecting section 132. The first guide section 131 has a first arc-shaped inner surface. The second heat-insulating brick 14 includes a second guide section 141 and a second connecting section 142. The second guide section 141 is connected to the second connecting section 142. The second guide section 141 has a second arc-shaped inner surface. The first arc-shaped inner surface and the second arc-shaped inner surface together form a flow guiding surface 12. The main body 10 of the insulating brick is composed of a first insulating brick 13 and a second insulating brick 14, which reduces the processing difficulty of the entire main body 10 of the insulating brick and avoids the problem of difficult operation due to the large volume of the main body 10 of the insulating brick. The first guide section 131 and the second guide section 141 are used to guide the glass liquid condensed on the main body 10 of the insulating brick. The first connecting section 132 and the second connecting section 142 are set on the mixing tank and fit in close to the mixing tank to ensure the sealing performance of the main body 10 of the insulating brick, thereby ensuring a good sealing effect.

[0035] As shown in Figures 1 to 4, in the technical solution of this embodiment, the first guide segment 131 has multiple limiting protrusions 1311, and the second guide segment 141 has multiple limiting grooves 1411. The multiple limiting protrusions 1311 and the multiple limiting grooves 1411 are arranged in a one-to-one correspondence. The arrangement of the multiple limiting protrusions 1311 and the multiple limiting grooves 1411 facilitates the positioning of the first insulation brick 13 and the second insulation brick 14, and forms mutual limiting, while increasing the contact area between the first insulation brick 13 and the second insulation brick 14, avoiding the problem of separation under force when the internal air pressure is high.

[0036] As shown in Figures 1 to 4, in the technical solution of this embodiment, the first guide segment 131 has a first arc-shaped outer surface, which is parallel to the first arc-shaped inner surface. The second guide segment 141 has a second arc-shaped outer surface, which is parallel to the second arc-shaped inner surface. This structure ensures that the thickness of the first insulating brick 13 and the second insulating brick 14 is uniform, avoiding localized overheating caused by uneven thickness, which could easily lead to deformation or breakage of the first insulating brick 13 or the second insulating brick 14.

[0037] As shown in Figures 1 to 4, in the technical solution of this embodiment, the projection of the inner surface of the first connecting section 132 along the vertical direction is outside the projection of the inner wall of the mixing tank along the vertical direction, and the projection of the inner surface of the second connecting section 142 along the vertical direction is outside the projection of the inner wall of the mixing tank along the vertical direction. When the condensed glass liquid flows down along the guide surface 12, it will fall to the upper edge of the mixing tank and will not fall back into the mixing tank, thus avoiding contamination of the glass liquid inside the mixing tank.

[0038] As shown in Figures 1 to 4, in this embodiment, the insulation brick structure further includes an operating section 20. The operating section 20 includes a first handle 21 and a second handle 22. The first handle 21 is connected to a first connecting section 132, and the second handle 22 is connected to a second connecting section 142. Both the first connecting section 132 and the second connecting section 142 are fitted into the mixing tank. Two first handles 21 and two second handles 22 are provided, facilitating the worker to pick up the first insulation brick 13 or the second insulation brick 14 with both hands. The operating section 20 facilitates the worker placing the first insulation brick 13 or the second insulation brick 14 on or removing it from the mixing tank.

[0039] As shown in Figures 1 to 4, in this embodiment, the main body 10 of the insulating brick is made of alumina. Alumina is stable at high temperatures, does not deform significantly when heated, and is not easily broken, thus ensuring the sealing performance of the main body 10 of the insulating brick.

[0040] As shown in Figures 1 to 4, in this embodiment, the operating part 20 further includes multiple heat insulation parts, which are respectively fitted onto the first handle 21 and the second handle 22. The first handle 21 and the second handle 22 can also be made of alumina material, and the first handle 21 and the first insulating brick 13 are integrally formed, as are the second handle 22 and the second insulating brick 14, to prevent breakage at the connection point and to facilitate processing. The heat insulation effectively insulates against high temperatures, preventing burns to workers holding the first handle 21 or the second handle 22.

[0041] As shown in Figures 1 to 4, in this embodiment, the heat insulation part is made of ceramic material. Alternatively, the heat insulation part can be made of mullite material, which has good heat insulation properties and is lightweight, reducing the difficulty of operation for workers.

[0042] According to another aspect of this application, a mixing tank is also provided. The mixing tank adopts the aforementioned heat-insulating brick structure. The mixing tank includes a mixing tank body and a stirring rod. The heat-insulating brick body 10 is placed on the mixing tank body, and the stirring rod passes through the stirring hole 11 and is partially located inside the mixing tank body. The heat-insulating brick body 10 is placed on the mixing tank body, and the stirring rod passes through the stirring hole 11 to stir the glass liquid inside the mixing tank. The setting of the heat-insulating brick body 10 keeps the internal glass liquid warm, avoiding energy waste caused by heat loss, and at the same time preventing external impurities from entering the mixing tank and affecting the purity of the glass liquid. The mixing tank body is provided with a snap-fit ​​structure, and the outer side of the heat-insulating brick body 10 is provided with a protrusion corresponding to the snap-fit ​​structure. After the heat-insulating brick body is placed on the mixing tank, the snap-fit ​​structure engages with the corresponding protrusion, further preventing the heat-insulating brick body 10 from moving and falling off.

[0043] As shown in Figure 1, this application is shaped like a "pot lid," with thick edges that extend downwards. The overall material is alumina. The lid brick (insulating brick body 10) is composed of two bricks: a first brick (first insulating brick 13) and a second brick (second insulating brick 14). The two bricks have grooves between them for mutual support, increasing stability and sealing. Each of the two bricks has a heat-insulating handle (operating part 20) on both sides, for a total of four handles, making it easier to pick up and place the insulating bricks. The heat-insulating handles are made of alumina, the same material as the insulating bricks, and are covered with mullite for insulation. A stirring hole 11 is located in the center of the first and second bricks. The stirring rod passes through this hole without contacting the stirring hole in the insulating brick, thus avoiding additional resistance. The insulating brick has thick edges that extend downwards, covering an area larger than the stirring tank. Therefore, the molten glass flows along the inner layer of the insulating brick towards the edge, eventually reaching the outer edge, preventing crystallization from falling into the stirring tank. This reduces glass melt contamination caused by crystallization falling into the mixing tank, thus improving the yield of finished glass products. When it is necessary to remove the insulating cover bricks, two people can each hold the first and second bricks respectively. Each insulating cover brick has a set of handles and is covered with heat-insulating material. One person can easily lift it by grasping the two handles of one brick with one hand. The handles are positioned slightly lower than the first and second bricks, ensuring stable force distribution during lifting and preventing them from falling, thus enhancing safety. The technical solution of this application solves the problem of crystallization falling into the mixing tank and affecting the quality of the glass melt, and makes moving the insulating cover bricks of the mixing tank safer and more convenient.
