[0002] Float glass has been widely used in many industries due to its advantages such as high flatness, good transparency, simple process and large output.

[0003] During the float glass production process, silicon carbon rods need to be controlled by transformers to heat the tin bath. The thinner the glass, the more electric heating zones there are, and the larger the number of transformers.

If the transformer layout is not designed properly, it will have a serious impact on the process adjustment of the top of the tin bath and the maintenance of the transformer, such as CN111423101B.

[0029] All terms used in this application have the same meaning as those understood by those of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] like Figures 1 to 3 As shown, the float glass tin bath top cover disclosed in the embodiment of the present application includes a frame assembly 10, a top cover assembly and a heating assembly 20, the top cover assembly is connected to the frame assembly 10, the heating assembly 20 includes multiple, the multiple heating assemblies 20 include a transformer structure 21 and a heating structure, the multiple transformer structures 21 are movably connected to the frame assembly 10, the multiple transformer structures 21 are arranged at intervals, the heating structure is connected to the transformer structure 21 and is arranged one-to-one, and the multiple heating structures are connected to the top cover assembly.

[0032] By applying the technical solution of this embodiment, multiple transformer structures 21 respectively control multiple heating structures, so that the tin bath has multiple electric heating zones to better control the glass thickness. The voltage provided by the transformer structure 21 corresponding to the heating structure with a higher temperature is larger, and the transformer structure 21 itself generates more heat. Similarly, the transformer structure 21 corresponding to the heating structure with a lower temperature itself generates less heat. Therefore, the minimum distance required for each transformer structure 21 to avoid mutual influence is different. Since the transformer structure 21 is movably connected to the frame assembly 10, the position of each transformer structure 21 can be adjusted according to different models of produced glass, so that the layout of the transformer structure 21 is reasonable. The technical solution of this embodiment effectively solves the problem of the prior art that in the process of float glass production, there is an unreasonable layout of the transformer at the top of the tin bath, which leads to a low transformer service life.

[0033] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the transformer structure 21 includes a transformer 211 and a support portion 212. The support portion 212 includes two, and the two support portions 212 are movably connected to the frame assembly 10. The transformer 211 is connected to the support portion 212 and is arranged away from the frame assembly 10. The support portion 212 is arranged at the bottom of the transformer 211, and is used to support the transformer 211. The support portion 212 is movably connected to the frame assembly 10, so the position of the transformer structure 21 on the frame assembly 10 can be changed, which is convenient for the staff to adjust the positions of multiple transformers 211 according to different working conditions. A groove that cooperates with the support portion 212 is arranged at the bottom of the transformer 211, and the support portion 212 is partially located in the groove at the bottom of the transformer 211.

[0034] like Figure 1 and Figure 3 As shown, in the technical solution of this embodiment, the spacing between adjacent transformers 211 is greater than 200 mm. A distance between adjacent transformers 211 less than 200 mm is not conducive to the heat dissipation of the transformer 211, multiple transformers 211 will affect each other, and it is not conducive to the installation and maintenance of the transformer by the staff.

[0035] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the frame assembly 10 includes a frame structure and a first support structure 11, the first support structure 11 is connected to the frame structure, the first support structure 11 includes a plurality of first support structures 11, the plurality of first support structures 11 are arranged parallel to the flow direction of the tin liquid in the tin bath, and the support portion 212 is movably connected to the first support structure 11. During the production process of float glass, the glass moves in the direction of the tin liquid flow, and the tin bath top cover needs to be adjusted with the movement of the glass. In order to avoid interference with the second support structure, the first support structure 11 is arranged parallel to the movement direction of the tin bath top cover, that is, the flow direction of the tin liquid.

[0036] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the first support structure 11 includes two fixing parts 111, the two fixing parts 111 are parallel to each other, the support part 212 has a fixing hole, the fixing hole is located at both ends of the support part 212, the fixing part 111 has a long hole, and a fastener is inserted between the long hole and the fixing hole. By loosening the fastener, the position of the support part 212 can be adjusted, and the support part 212 can be adjusted along the length direction of the long hole, that is, the flow direction of the tin liquid. By adjusting the positions of multiple support parts 212, not only the distance between multiple transformers 211 can be adjusted, but also different transformers can be replaced according to different working conditions.

[0037] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the projection of the transformer 211 in the vertical direction is located between the projections of the two fixing parts 111 in the vertical direction. Since the projection of the transformer structure 21 in the vertical direction is located between the projections of the two fixing parts 111 in the vertical direction, the projection of the transformer 211 in the vertical direction is located between the fasteners used to connect the fixing parts 111 and the supporting parts 212, which further facilitates the adjustment of the position of the transformer.

[0038] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the frame assembly 10 also includes a second support structure 12, which is connected to the frame structure, and the second support structure 12 is arranged parallel to the first support structure 11, and the top cover assembly is connected to the second support structure 12. During the glass production process, the glass moves along the flow direction of the tin liquid, and the top cover assembly needs to be appropriately adjusted along the movement of the glass, so the top cover assembly needs to be adjusted along the flow direction of the tin liquid. The second support structure 12 includes an I-shaped beam and a moving trolley, and the I-shaped beam is arranged parallel to the first support structure 11. The moving trolley is movably connected to the I-shaped beam. To ensure the balance of the top cover assembly, the moving trolley and the I-shaped beam are both provided with multiple. The moving trolley includes two sets of rollers, and the two sets of rollers are respectively arranged at the narrower part in the middle of the I-shaped beam and the bottom of the I-shaped beam, so as to ensure that the entire moving trolley moves smoothly and will not tip over. The parallel arrangement of the first support structure 11 and the second support structure 12 further ensures the rationality of the entire layout.

[0039] like Figures 1 to 3As shown, in the technical solution of this embodiment, the second support structure 12 includes a plurality of second support structures 12, and the plurality of second support structures 12 are respectively arranged between adjacent first support structures 11, and the top cover assembly is arranged on the side of the first support structure 11 away from the transformer structure 21. The plurality of second support structures 12 are arranged to ensure that the top cover assembly will not tilt, and the plurality of second support structures 12 are respectively arranged between adjacent first support structures 11. While ensuring that the second support structures 12 are evenly distributed, it is ensured that there is a certain distance between adjacent transformers in a direction perpendicular to the flow direction of the tin liquid, and further ensures a good heat dissipation effect.

[0040] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the heating structure includes a heating part and a wire, the first end of the wire is connected to the heating structure, the second end of the wire is connected to the transformer structure 21, and the heating part is arranged in the top cover assembly. The heating part uses a silicon carbon rod, which is arranged in the top cover assembly. When the wire is energized, the temperature of the silicon carbon rod can be changed. By controlling the pressure of multiple transformers 211, the temperature of different silicon carbon rods connected thereto is different. The top cover assembly has multiple different electric heating zones to adapt to the production of thinner float glass.

[0041] In the glass production process, since the glass floats on the surface of the tin liquid and flows with it, the surface of the tin liquid will fluctuate. The shape of the glass edge is greatly affected by the flow of the tin liquid, while the shape of the glass center is less affected by the flow of the tin liquid. Therefore, the temperature of the heating zone relative to the glass edge is higher, and the temperature in the middle is lower. The voltage of the corresponding transformer 211 at the edge is larger, and the heat dissipation is too much. The voltage of the transformer 211 at the center is smaller, and the heat dissipation is less. Therefore, during the layout process, the transformer 211 at the center can be made denser than the transformer 211 at the edge, and then adjusted according to different working conditions to reduce the number of adjustments and the adjustment time, thereby improving work efficiency.

[0042] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the float glass tin bath top cover also includes a detection component, which is arranged on the top cover component, and the detection component is arranged one-to-one with the heating component 20. The detection component uses a thermocouple, which is arranged corresponding to different heating partitions. The thermocouple converts the temperature of the corresponding heating partition into an electrical signal and transmits it to the control terminal, so that the staff can timely supervise and control the working status.

[0043] From the above, it can be known that the spacing of the fixing holes (fixing holes on the support part 212) of the transformer at the top of the tin bath (transformer structure 21) is consistent. The length of the transformer base crossbeam (support part 212) of the transformer at the top of the tin bath is consistent. The inner width W1 of the transformer support steel beam (two fixing parts 111) is between 20-150mm smaller than the upper and lower dimensions L1 of the fixing hole. The outer width W2 of the transformer support steel beam is between 0-20mm smaller than the length L2 of the transformer base crossbeam. The spacing size between transformers 211 is designed to be: ≥200mm. The installation position of the transformer support steel beam cannot affect the process adjustment. The layout method of the transformer at the top of the tin bath of the present application includes: 1. Transformer support steel beams, each row of transformers 211 requires 2 transformer support steel beams (fixing parts 111); 2. Tin bath electric heating partitions; 3. Transformer 211; 4. Transformer numbering; 5. Large process steel beam (second support structure 12). The layout method of this application is described in detail: Transformer support steel beam: fixed on the frame (frame structure) of the large process steel beam, with a certain distance from the large process steel beam, used to install and fix transformer 211; Tin bath electric heating partition: provide a heat field for the inside of the tin bath by electric heating, the entire tin bath electric heating partition (top cover assembly) is suspended on the large process steel beam by steel columns, and can be moved slowly back and forth manually during work; Transformer 211: provide power energy with variable power for the tin bath electric heating partition, connected together by multiple cables with larger diameters, the transformer is installed on 2 transformer support steel beams, and there must be a spacing size between transformers 211 in the same row, and the spacing size is greater than 200mm; 4. Transformer numbering: the installation position and serial number of each transformer are reflected on the layout diagram, and the transformer number may not be marked on the transformer body. Design process description: 1. Design principles. Proximity principle: The transformer is installed near the corresponding electric heating partition; Left and right row principle: Because the tin bath is divided into a hot end and a cold end, the process steel beams of the hot end and the cold end are connected from left to right, and the entire tin bath top cover and electric heating are suspended on the process steel beam through steel columns and can be moved left and right, so the transformer support steel beam must be parallel to the process steel beam, and the transformer is fixed from left to right; Spacing principle: The transformer itself will generate heat during work, and the transformer needs a certain maintenance space, so the W4 spacing size between the transformers is designed to be: ≥200mm. 2. Design method. First: According to the layout of the tin bath electric heating partition on the top of the tin bath, how many rows of transformers 211 are needed to design. In this application, there are 7 rows of tin bath electric heating partitions above and below. Each tin bath electric heating partition needs to be equipped with at least one transformer 211. According to the design principle, the left and right length of the electric heating partition is at most 2 transformers 211, so at least 4 rows need to be designed above and below. In this way, the layout design of 7 transformers 211 can be completed.Second: In order to facilitate the installation of transformers and the design of transformer support steel beams, the base beam length L2 of all transformers is required to be consistent, the upper and lower lengths L1 of the fixing holes are consistent, the fixing holes, the transformer base beams, and the upper and lower lengths L1 of the fixing holes are 700-950mm, and 800mm is preferred. In this way, the spacing W1 inside the transformer support steel beam is guaranteed to be 650-780mm to meet the fixing requirements; due to the heavy weight of transformer 211, it is recommended that the base beam length L2 is at least consistent with the maximum spacing W2 of the 1 transformer support steel beam, and the exposed length of the base beam length L2 at both ends does not exceed 10mm; the spacing W3 between the transformer support steel beam and the process large steel beam is ≥150mm, which is convenient for process adjustment. Third: Thermocouples need to be installed on the top of the tin bath. Thermocouples are installed after the transformer is installed. Therefore, when the transformer and the thermocouple conflict, the spacing of the transformer is adjusted left and right to avoid the thermocouple position. Fourth: The transformer can be adjusted around the corresponding electric heating partition, no more than 10 meters away from the center of the electric heating partition. Through the above method, the layout design of the tin bath transformer can be completed quickly and safely.
