[0022] To describe in detail the technical content, achieved objectives and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the drawings.

[0023] As Figure 1 and Figure 2 , the present invention provides an edge brick structure for calendered glass, which is installed on the overflow port of calendered glass, and includes a lip brick 1 and an edge brick 2. A bracket sleeve 3 made of stainless steel is provided between the edge brick 2 and the lip brick 1.

[0024] As can be seen from the above description, the beneficial effects of the present invention are as follows: In the edge brick structure for calendered glass of the present invention, a bracket sleeve 3 made of stainless steel is provided at the bottom end of the edge brick 2.

It avoids the direct contact between the head of the edge brick 2 and the glass liquid in a high-temperature molten state, effectively reduces the erosion degree of the head of the edge brick 2, effectively extends the service life of the edge brick 2, lengthens the machine change time cycle, improves the effective production time, reduces the production cost, and improves the economic benefits. Further, due to the non-wetting physical and chemical characteristics of the bracket sleeve 3 made of stainless steel with the high-temperature molten glass liquid, it can better perform the smooth dissociation and edge closing of the edge of the high-temperature molten glass liquid. Therefore, it can perfectly achieve the effective and precise control of the smooth edge during the expansion of the ultra-white photovoltaic calendered glass, and achieve the minimum edge loss.

[0025] Furthermore, in the above-mentioned edge brick structure for calendered glass, the bracket sleeve 3 includes a bottom wall in the horizontal direction and a side wall sleeved on the bottom end of the edge brick 2.

[0026] As can be seen from the above description, the bracket sleeve 3 includes a bottom wall in the horizontal direction and a side wall sleeved on the bottom end of the edge brick 2. The above structure enables the bracket sleeve 3 to be sleeved on the bottom end of the edge brick 2.

[0027] Furthermore, in the above-mentioned edge brick structure for calendered glass, a circular notch for accommodating the side wall of the bracket sleeve 3 is provided at the bottom edge of the edge brick 2.

[0028] As can be seen from the above description, setting the circular notch to accommodate the bracket sleeve 3 makes the bracket sleeve 3 and the edge brick 2 more integrated, with a firm connection, and also avoids unevenness in the contact surface with the glass liquid, resulting in uneven temperature.

[0029] Furthermore, in the above-mentioned edge brick structure for calendered glass, the edge brick 2 includes a brick body. A lip brick 1 is provided at the lower end of the brick body. A relief arc surface for relieving the roller is provided on the side of the brick body facing the roller of the calender. The bottom end of the relief arc surface is inwardly hooked to form a card slot for accommodating the end of the lip brick 1.

[0030] Furthermore, in the above-mentioned edge brick structure for calendered glass, the lowermost end of the relief arc surface is lower than the bottom surface of the brick body.

[0031] As can be seen from the above description, setting the card slot can block the gap between the edge brick 2 and the lip brick 1.

[0032] Furthermore, in the above-mentioned edge brick structure for calendered glass, a steel beam 4 is provided at the bottom of the overflow port. The lip brick 1 is slidably connected to the upper surface of the steel beam 4. Fixed brackets 5 are respectively provided at both ends of the steel beam 4. A kidney-shaped hole 6 is provided on the fixed bracket 5. The length direction of the kidney-shaped hole 6 is the axial direction of the lip brick 1. A slider is slidably connected to the kidney-shaped hole 6;

[0033] An installation groove is provided on the top surface of the edge brick 2. An adjusting plate 7 is fixedly connected in the installation groove. One end of the adjusting plate 7 is connected to the installation groove, and the other end is connected to the slider.

[0034] As can be seen from the above description, setting the fixed bracket 5 enables the edge brick 2 to move, for edge reduction or edge expansion.

[0035] Furthermore, in the above-mentioned edge brick structure for calendered glass, two screw holes are provided at the bottom of the installation groove. The adjusting plate 7 is connected in the screw holes through a connecting piece.

[0036] Furthermore, in the above-mentioned edge brick structure for calendered glass, a first tightening bolt 8 is provided on the fixed bracket 5. One end of the first tightening bolt 8 is threadedly connected to the fixed bracket 5, and the other end presses against the edge brick 2.

[0037] As can be seen from the above description, setting the first tightening bolt 8 can cooperate with the adjusting plate 7 to make the edge brick 2 more stable after moving.

[0038] Furthermore, in the above-mentioned edge brick structure for calendered glass, a second tightening bolt 9 is provided on the fixed bracket 5. One end of the second tightening bolt 9 is threadedly connected to the fixed bracket 5, and the other end is connected to the lip brick 1 through a tightening spring.

[0039] As described above, the second tightening bolt 9 is provided to stably fix the lip brick 1, and the tightening spring is cooperatively provided to avoid the influence of the thermal expansion and contraction of the lip brick 1 on the fixing stability.

[0040] Furthermore, in the above-mentioned edge brick structure for calendered glass, the bracket sleeve 3 is made of 316 stainless steel plate, and the thickness of the stainless steel plate is 5 - 30 mm.

[0041] As described above, due to the physical and chemical characteristics of the non-wetting property of 316 stainless steel with high-temperature molten glass liquid, the smooth dissociation and edge-closing effect of the edge of the high-temperature molten glass liquid can be better carried out. Therefore, the effective and precise control of the smooth edge during the shrinkage of the ultra-white photovoltaic calendered glass can be perfectly realized, and the minimum light edge loss can be achieved.

[0042] Embodiment 1

[0043] The application scenario of this embodiment is as follows: During the production process of ultra-white photovoltaic calendered glass, the ultra-white photovoltaic glass liquid that has been melted at high temperature, after high-temperature clarification, flows from the passage to the overflow port, and the high-temperature molten glass liquid then flows into the calender through the lip brick 1 and the edge bricks 2 on both sides to form.

[0044] Currently, the commonly used edge bricks 2 and lip bricks 1 in enterprises are prepared from refractory materials such as sillimanite materials or zircon mullite. The surfaces of these refractory materials are relatively rough. At high temperatures, the glass liquid is prone to adhere to the refractory materials. In addition, due to the heat dissipation effect of the surfaces of these refractory materials, the temperature of the inner surface (the surface of the edge brick 2 or the support brick in contact with the glass liquid) decreases, the temperature of the glass liquid adhering to the inner surface decreases, the glass viscosity increases, the flow rate of the glass liquid slows down, and more and more glass liquid adheres to the inner surfaces of the edge brick 2 and the support brick. When the temperature drops to the crystallization temperature of the glass, glass crystallization occurs. After crystallization occurs at the edge brick 2, the size of the glass sheet becomes narrower, seriously affecting the product output and quality.

[0045] Please refer to Figure 1-2 , in view of the above problems, this embodiment provides an edge brick structure for calendered glass, which is installed on the overflow port of the calendered glass and includes a lip brick 1 and an edge brick 2. A bracket sleeve 3 made of stainless steel is provided between the edge brick 2 and the lip brick 1.

[0046] The bracket sleeve 3 includes a bottom wall in the horizontal direction and a side wall sleeved on the bottom end of the edge brick 2. A circular notch for accommodating the side wall of the bracket sleeve 3 is provided at the bottom edge of the edge brick 2.

[0047] The edge-blocking brick 2 includes a brick body. A lip brick 1 is provided at the lower end of the brick body. A relief arc surface for the roller is provided on the side surface of the brick body facing the roller of the calender. The bottom end of the relief arc surface is inwardly hooked to form a card slot for accommodating the end of the lip brick 1. The lowermost end of the relief arc surface is lower than the bottom surface of the brick body.

[0048] In the above-mentioned edge-blocking brick structure for calendered glass, a steel beam 4 is provided at the bottom of the overflow port. The lip brick 1 is slidably connected to the upper surface of the steel beam 4. Fixed brackets 5 are respectively provided at both ends of the steel beam 4. A kidney-shaped hole 6 is provided on the fixed bracket 5. The length direction of the kidney-shaped hole 6 is the axial direction of the lip brick 1. A slider is slidably connected to the kidney-shaped hole 6;

[0049] An installation groove is provided on the top surface of the edge-blocking brick 2. An adjusting plate 7 is fixedly connected in the installation groove. One end of the adjusting plate 7 is connected to the installation groove, and the other end is connected to the slider.

[0050] Two screw holes are provided at the bottom of the installation groove. The adjusting plate 7 is connected in the screw holes through connecting pieces.

[0051] A first tightening bolt 8 is provided on the fixed bracket 5. One end of the first tightening bolt 8 is threadedly connected to the fixed bracket 5, and the other end presses against the edge-blocking brick 2.

[0052] A second tightening bolt 9 is provided on the fixed bracket 5. One end of the second tightening bolt 9 is threadedly connected to the fixed bracket 5, and the other end is connected to the lip brick 1 through a tightening spring.

[0053] The bracket sleeve 3 is made of 316 stainless steel plate, and the thickness of the stainless steel plate is 5 - 30 mm.

[0054] The use of the above-mentioned edge-blocking brick structure for calendered glass:

[0055] High-quality low-iron glass raw materials are formulated, transported, fed, melted, and clarified. The molten high-quality glass liquid flows from the passage to the lip brick. On both side edges of the thin molten high-temperature glass liquid on the lip brick, under the blocking action of the steel-nickel composite edge-blocking brick, it enters the calender. Under the action of the calender, the edges of the high-temperature molten glass liquid thin plate shrink to form smooth edges.

[0056] When the plate width needs to be adjusted according to the order requirements, such as reducing the plate, adjust the adjusting plate connected to the edge retaining brick, and push the edge retaining brick to slide inward. The bracket made of 316 stainless steel slides freely on the lip brick with less friction. Therefore, no white refractory stone will be generated due to the falling of fine refractory debris during plate reduction, which will affect the plate surface quality. When expanding the plate, the situation is the same as that of reducing the plate. Due to the non-wetting physical and chemical characteristics of the bracket sleeve made of the above-mentioned 316 special stainless steel and the high-temperature molten glass liquid, the smooth dissociation and edge closing of the edge of the high-temperature molten glass liquid can be better carried out. Therefore, the effective and precise control of the smooth edge can be perfectly realized when expanding the plate of the ultra-white photovoltaic rolled glass, and the minimum edge loss can be achieved.

[0057] When the existing edge retaining brick does not have a bracket sleeve, the original edge loss of the ultra-white photovoltaic rolled glass is about 11-13%. After the successful research of the present invention, when the edge retaining brick is changed to the edge retaining brick structure of the rolled glass in the above embodiment, the edge loss of the glass plate is reduced to about 5-6%, and the edge loss is reduced by more than 6-7%. The loss of white refractory stones of more than 2% and the breakage of the edge retaining brick are eliminated.

[0058] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the related technical fields, shall be included in the patent protection scope of the present invention by the same token.
