Description

Technical Field

[0001] The utility model belongs to the technical field of float glass preparation, and more specifically relates to a float glass tin bath structure. Background Art

[0002] In the process of float glass preparation, one of the links of float glass is passing through the tin bath. The tin bath is the most important core thermal equipment on the float glass production line. The float glass that passes through the tin bath is a long strip of glass. When the glass ribbon passes through the tin liquid in the tin bath, it will contact the side wall. In order to prevent the glass ribbon from directly contacting the edge bricks and being damaged, a graphite block needs to be set. In the tin bath structure of the prior art, the graphite block is hung on the inner side of the edge brick. In this way, the graphite block is very easy to be damaged during the operation of the tin bath, and the cut graphite block is not easy to replace. After the graphite block is damaged, the plate width is too wide, which is easy to cause edge contact accidents, affecting the operation safety and product quality.

[0003] In the prior art, there is a technology named "a tin bath structure for flat glass manufacturing" and the publication number is "CN 202543034U". This technology solves the technical problem that the tin bath structure for float glass substrate production in the prior art cannot prevent the tin liquid from volatilizing from both sides of the glass ribbon or the glass ribbon is bonded to the tin bath wall bricks, thereby causing poor quality of the finished glass or a production accident that is very likely to occur. The technical scheme adopted is that it includes a tin bath made of bottom bricks and wall bricks, a tin bath top cover, and a flowing tin liquid conveyor belt arranged at the bottom of the bath. The glass liquid floats on the upper surface of the tin liquid conveyor belt, and there are anti-bonding gaps between the two sides and the wall bricks. In the gap between the glass liquid and the wall bricks, a graphite cover plate with a bottom surface not higher than the upper surface of the glass liquid is added, and the graphite cover plate is positioned on the wall bricks of the tin bath. The utility model adds a graphite cover plate above the exposed tin liquid, which not only avoids the glass ribbon from being bonded to the wall bricks due to being too wide, thereby causing a production accident, but also avoids the problem of tin liquid volatilization and contamination of the glass ribbon due to being too narrow, thereby improving the qualified rate of finished products.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in view of the deficiencies in the prior art, a float glass tin bath structure is provided which has a simple structure and can conveniently and reliably realize the arrangement of graphite blocks on edge bricks, the graphite blocks are reliably positioned and reliably protected, are not easily damaged, and are convenient to replace.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the utility model is:

[0007] The utility model relates to a float glass tin bath structure. The side of the tin bath body is provided with side bricks, the inner side of the side bricks is provided with a concave platform near the upper part, and a graphite stopper is provided in the concave platform.

[0008] An upper limiting plate is arranged on the upper part of the edge brick, and the upper limiting plate is simultaneously attached to the upper surface of the graphite stopper.

[0009] A left side brick is arranged on one side of the tin bath body, and a right side brick is arranged on the other side of the tin bath body.

[0010] A concave platform is arranged on the inner side surface of the left side brick near the upper part, and a graphite stopper is arranged in the concave platform.

[0011] A concave platform is arranged on the inner side surface of the right side brick near the upper part, and a graphite stopper is arranged in the concave platform.

[0012] A side limiting plate is arranged on the outer side of the edge brick, and the upper end of the side limiting plate is fixedly connected to the outer side of the upper limiting plate by bolts.

[0013] When a graphite stopper is arranged in the concave platform, the bottom surface of the graphite stopper fits the bottom surface of the concave platform, and the rear side of the graphite stopper fits the side surface of the concave platform.

[0014] The float glass is a glass strip. When the float glass passes through the float glass tin bath structure, one side of the float glass is configured to be able to contact the graphite stopper on the left side brick, and the other side of the float glass is configured to be able to contact the graphite stopper on the right side brick.

[0015] The upper limiting plate and the side limiting plate are metal plates.

[0016] The lower end of the side limiting plate is fixedly connected to the tin bath base.

[0017] The technical solution of the utility model is adopted, and the working principle and beneficial effects are as follows:

[0018] The float glass tin bath structure described in the utility model has side bricks arranged on the sides of the tin bath body to form a tin bath body, and the tin bath body is used for float glass to pass through. When the side bricks are arranged, the side bricks are partially arranged as a special-shaped structure, that is, a concave platform is arranged near the upper part of the inner side surface of the side brick, and the vertical section height of the concave platform is equal to the vertical section height of the graphite stopper, and the vertical section width of the concave platform is equal to the vertical section width of the graphite stopper, so that the concave platform is used to reliably arrange the graphite stopper. In this way, multiple side bricks are arranged on both sides, and multiple graphite stoppers are also arranged on each side. The side bricks and the graphite stoppers extend along the length direction of the tin bath structure to form two graphite stopper strips. When the float glass passes through the tin bath structure, it floats through the tin liquid in the tin bath structure. At this time, each side of the float glass only contacts the graphite stopper, and does not contact the side bricks, because the performance of the graphite stopper is good, the hardness is good, the wear resistance is good, and the surface is smooth, and the float glass will not be damaged during the contact process. At the same time, the graphite stopper is not easy to be damaged, so it will not fall off, reducing the impurities formed by falling off and entering the tin liquid. Float glass will not contact the edge bricks, which prevents the edge bricks from damaging the glass, or the edge bricks from frequently contacting the glass and falling off, which will increase the amount of debris in the tin liquid. At the same time, the graphite block is arranged in the concave part, which is convenient for removal and replacement, and the graphite block can be replaced individually, which is convenient and labor-saving, avoiding excessive impact on normal production progress due to replacement of graphite blocks.

When the structure is set, the side bricks 2 are arranged on the side of the tin bath body respectively, so as to form a tin bath body, and the tin bath body is used for float glass (glass ribbon) to pass through. When the side brick 2 structure is set, the side brick 2 is partially set as a special-shaped structure, that is, the inner side surface 3 of the side brick 2 is arranged near the upper part of the concave platform 4, the vertical section height of the concave platform 4 is equal to the vertical section height of the graphite stopper 5, and the vertical section width of the concave platform 4 is equal to the vertical section width of the graphite stopper 5, so that the concave platform 4 is used to reliably arrange the graphite stopper 5. In this way, multiple side bricks 2 are arranged on both sides, and multiple graphite stoppers 5 are also arranged on each side. The side bricks 2 and the graphite stoppers 5 extend along the length direction of the tin bath structure to form two graphite stopper strips. When the float glass (glass ribbon) passes through the tin bath structure, it floats through the tin liquid in the tin bath structure. At this time, each side of the float glass 11 only contacts the graphite block 5, but does not contact the edge brick 2, because the performance of the graphite block 5 is good, the hardness is good, the wear resistance is good, and the surface is smooth. The float glass 11 will not be damaged during the contact process. At the same time, the graphite block 5 is not easy to be damaged, and will not fall off, reducing the impurities that fall off and enter the tin liquid. The float glass 11 will not contact the edge brick 2, which can avoid the edge brick 2 damaging the glass, or the edge brick 2 frequently contacts the float glass 11 and falls off, resulting in an increase in the sundries in the tin liquid. At the same time, the graphite block 5 is arranged in the concave platform 4, which is convenient to take out and replace, and the graphite block 5 can be replaced individually, which is convenient and labor-saving, and avoids excessive impact on normal production due to the replacement of the graphite block 5.

The side bricks 2 and the graphite stoppers 5 extend along the length direction of the tin bath structure to form two graphite stopper strips. When the float glass (glass ribbon) passes through the tin bath structure, it floats through the tin liquid in the tin bath structure. At this time, each side of the float glass 11 only contacts the graphite block 5, but does not contact the edge brick 2, because the performance of the graphite block 5 is good, the hardness is good, the wear resistance is good, and the surface is smooth. The float glass 11 will not be damaged during the contact process.
