The temperature difference between the upper and lower surfaces of the lip brick is very large, so that there is a large stress difference between the upper and lower parts of the lip brick. When the stress difference between the upper and lower parts is too large, the lip brick will deform, and in severe cases, the lip brick will crack or break, causing damage to the equipment and loss of production line shutdown. At the same time, the large temperature difference between the upper and lower surfaces of the lip brick will also cause a large amount of material crystallization at the end of the lip brick, affecting the quality of the formed material.

[0043] Please refer toFigure 1 and Figure 2 , Figure 1 is a first perspective structural schematic view of the lip brick assembly 10 disclosed by the embodiments of the present disclosure; Figure 2 is a top structural schematic view of the lip brick assembly 10 disclosed by the embodiments of the present disclosure. In a first aspect, the embodiments of the present disclosure provide a lip brick assembly 10, comprising a brick body 110 and a plurality of heating rods 120. The brick body 110 has a plurality of through holes 110a, the plurality of through holes 110a communicate two opposite side surfaces 110b of the brick body 110, and the plurality of through holes 110a are arranged in a direction of travel of a molten material conveyed by the brick body 110; and the plurality of heating rods 120 are correspondingly arranged in the plurality of through holes 110a for heating the brick body 110. It can be understood that the lip brick assembly 10 provided by the embodiments of the present disclosure is applied to the production of glass, especially to the production of photovoltaic glass. Specifically, the lip brick assembly 10 is used to convey the molten material flowing out of a furnace 20 to a calender 30. When the lip brick assembly 10 provided by the embodiments of the present disclosure is used to convey the molten material, one side of the brick body 110 of the lip brick assembly 10 is arranged at an outlet of the furnace 20 to receive the molten material flowing out of the furnace 20, and the molten material forms a molten pool on an upper surface 112a of the brick body; and the other side of the brick body 110 is arranged corresponding to an inlet of the calender 30 to stably convey the molten material in the molten pool to the calender 30.

[0044] The brick body 110 has a plurality of through holes 110a communicating two opposite side surfaces 110b of the brick body 110. It can be understood that the through holes 110a are arranged between the upper surface 112a and the lower surface 112b of the brick body 110, and the through holes 110a are used to arrange the heating rods 120 to heat the brick body 110, thereby reducing the temperature difference between the upper surface 112a and the lower surface 112b of the brick body 110. In some embodiments, the diameter of the through hole 110a is equal to or slightly larger than the diameter of the heating rod 120, so that the inner surface of the through hole 110a is in close contact with the peripheral surface 110b of the heating rod 120, thereby enabling the heating rod 120 and the brick body 110 to be closely connected without falling off without the need for fixing components.

[0045] The through holes 110a are arranged in the direction of travel of the molten material conveyed by the brick body 110. It can be understood that the direction of travel refers to the direction of the molten material flowing out of the furnace 20 to the inlet of the calender 30 via the lip brick assembly 10. The arrangement of the through holes 110a in the direction of travel of the molten material enables the heating rods 120 arranged in the through holes 110a to effectively heat the part of the brick body 110 passing through the molten material.

[0046] The through holes 110a are arranged at intervals in the direction of the molten material. Understandably, the part of the brick 110 close to the inlet of the calender 30 is provided with the through holes 110a, so that the heating rod 120 can be arranged at the part of the brick 110 close to the inlet of the calender 30 and heat the part during the transportation of the material, so as to avoid the temperature of the end part 113c of the brick 110 being lower than the melting point of the molten material, which causes the material to crystallize.

[0047] The plurality of heating rods 120 are correspondingly arranged in the plurality of through holes 110a. Understandably, the heating rod 120 can be arranged inside the through hole 110a, and the heating rod 120 can also include a part extending out of the side surface 110b of the brick 110. In some embodiments, the two ends of the heating rod 120 extend out of the two opposite side surfaces 110b of the brick 110, so that the heating effect of the heating rod 120 on the brick 110 is better. The heating rod 120 can be, but is not limited to, a silicon-carbon heating rod or a silicon-molybdenum heating rod, and the material of the heating rod 120 is not limited in the present disclosure.

[0048] The lip brick assembly 10 disclosed in the embodiment reduces the temperature difference between the upper and lower surfaces of the brick 110 when the molten material is transported, avoids the deformation, cracking and even breaking of the lip brick caused by the temperature difference, and avoids the damage of the equipment and the shutdown of the production line; thereby prolonging the service life of the lip brick assembly 10 and reducing the cost of material production. At the same time, the heating rod 120 also heats the part of the brick 110 close to the inlet of the calender 30, so that the temperature of the end part 113c of the brick 110 is higher than the melting point of the material; so as to avoid the molten material crystallizing at this part, affecting the quality of the formed material, damaging the production equipment, and increasing the cost of manual cleaning of the material crystals.

[0049] Please refer to Figure 3 , Figure 3 is another front view structure schematic diagram of the lip brick assembly 10 disclosed in the embodiment of the present disclosure. In some embodiments, the brick 110 includes a support part 111 and a conveying part 112. The support part 111 is used to be connected with the kiln 20 and is used to receive the molten material flowing out of the kiln 20; the conveying part 112 is connected with one side of the support part 111 and is used to convey the molten material flowing out of the kiln 20 to the calender 30.

[0050] The brick body 110 comprises a supporting part 111 and a conveying part 112. In some embodiments, the supporting part 111 is integrally connected with the upper surface of the conveying part 112 to form the upper surface 112a of the brick body 110. The two opposite side surfaces of the supporting part 111 and the conveying part 112 are integrally connected respectively to form the two opposite side surfaces 110b of the brick body 110. When the lip brick assembly 10 is used to convey the molten material, the molten material flowing out of the kiln 20 passes through the upper surface 112a of the corresponding part of the supporting part 111 and the conveying part 112 in turn to the inlet of the calender 30.

[0051] The supporting part 111 is used to connect with the kiln 20 to receive the molten material flowing out of the kiln 20. In some embodiments, the supporting part 111 is in the shape of a quadrangular prism, one side of which is used to connect with the kiln 20 to fix the lip brick assembly 10.

[0052] The conveying part 112 is used to convey the molten material flowing out of the kiln 20 to the calender 30. In some embodiments, the upper surface 112a of the brick body 110 is horizontally arranged, and the lower surface 112b of the conveying part 112 is arranged in an inclined manner. The height of the conveying part 112 gradually decreases along the direction of the molten material.

[0053] In some embodiments, the supporting part 111 has a surface facing the calender 30 outside the lip brick assembly 10. The surface is connected with the lower surface 112b of the conveying part 112 by bending, and the included angle between the surface and the lower surface 112b of the conveying part 112 is obtuse. It can be understood that the height of the supporting part 111 is higher than the height of the conveying part 112.

[0054] Please refer again to Figure 3 In some embodiments, the brick body 110 further comprises a flow guiding part 113 connected with the side of the conveying part 112 away from the supporting part 111. The flow guiding part 113 has a flow guiding inclined surface 113a connected with the upper surface 112a of the conveying part 112 by bending. The flow guiding inclined surface 113a is used to guide the molten material to the upper and lower calender rollers 31 of the calender 30.

[0055] It can be understood that the flow guiding part 113 and the flow guiding inclined surface 113a disclosed in the embodiments can guide the molten material on the conveying part 112 to the calender 30. In some embodiments, the two opposite side surfaces of the flow guiding part 113 are integrally connected with the two opposite side surfaces 110b of the brick body 110 and the two side surfaces of the conveying part 112 respectively.

[0056] In some embodiments, the guide portion 113 further has a lower inclined surface 113b connected to the lower surface 112b of the conveying portion 112 by bending, and the lower inclined surface 113b is further connected to the guide inclined surface 113a by a circular-arc-shaped chamfer to form an end portion 113c. In the related art, when the lip brick is used for material conveying, the temperature of the end of the guide portion 113 away from the conveying portion 112 is relatively low, and the lower edge of the end portion 113c is prone to precipitate material crystals. The lip brick assembly 10 disclosed in the embodiments of the present disclosure sets a heating rod 120 inside the brick body 110 to increase the temperature of the end portion 113c, thereby avoiding the lower edge of the end portion 113c from precipitating material crystals to affect the quality of the formed material.

[0057] Please refer again to Figure 3 In some embodiments, part of the through holes 110a are arranged on the support portion 111, and part of the through holes 110a are arranged on the conveying portion 112; and / or the through holes 110a are arranged vertically to the side surface 110b.

[0058] In some embodiments, the brick body 110 has five through holes 110a, three of which are arranged vertically and uniformly on the support portion 111 of the brick body 110, and the other two through holes 110a are arranged uniformly on the conveying portion 112 of the brick body 110, and the distance from the axis of the through hole 110a on the conveying portion 112 to the upper surface 112a and the lower surface 112b of the conveying portion 112 is approximately equal. It can be understood that the above-mentioned embodiments are examples of the arrangement of the through holes 110a in the present embodiment, and should not be understood as a limitation on the arrangement of the through holes 110a in the present embodiment. The positions of the through holes 110a can be reasonably arranged according to the shape and size of different brick bodies 110.

[0059] It can be understood that the through hole 110a arranged close to the guide portion 113 can heat the guide portion 113 by arranging the heating rod 120 inside the through hole 110a, thereby avoiding the lower edge of the end portion 113c from precipitating crystals.

[0060] It can be understood that the through hole 110a is arranged vertically to the side surface 110b, so that the heating rod 120 arranged inside the through hole 110a is perpendicular to the side surface 110b of the brick body 110, thereby improving the heating efficiency of the heating rod 120 and making the temperature of each part of the lower surface 112b of the brick body 110 more uniform.

[0061] Please refer again to Figure 2 In some embodiments, the lip brick assembly 10 further comprises a terminal 130 arranged on the end portion 121 of the heating rod 120 for electrical connection with an external power supply device.

[0062] It can be understood that, in the embodiment, the heating rod 120 is an electric heating rod 120; and the heating rod 120 comprises a heating portion and a wiring portion, the wiring portion is located at both ends of the heating rod 120, and is provided with a wiring terminal 130 for being connected to a power supply device to provide electric energy for the heating rod 120. The heating portion converts the electric energy into heat energy to heat the brick body 110.

[0063] In some embodiments, the heating portion is arranged inside the through hole 110a, and both ends of the heating portion protrude from the side surface 110b of the brick body 110, so that the heating effect of the heating rod 120 on the brick body 110 is better.

[0064] Please refer to Figure 2 In some embodiments, the lip brick assembly 10 further comprises a first support 140, and the first support 140 is arranged on both sides of the brick body 110 and connected to the part of the heating rod 120 protruding from the side surface 110b.

[0065] It can be understood that the lip brick assembly 10 can comprise two first supports 140, and the two first supports 140 are arranged on both sides of the brick body 110 and spaced apart from the side surface 110b of the brick body 110.

[0066] It can be understood that the first support 140 can also be fixedly connected with an external support or an external kiln 20 to fix the lip brick assembly 10; and the first support 140 can also be connected with multiple heating rods 120 to connect the multiple heating rods 120 of the lip brick assembly 10 into a whole, so as to improve the compactness of the lip brick assembly 10 and avoid the heating rod 120 from falling off the brick body 110.

[0067] Please refer to Figure 4 , Figure 4 is a structural schematic diagram of the calendering device 1 disclosed in the embodiment of the present disclosure. In a second aspect, the embodiment of the present disclosure provides a calendering device 1, which comprises a kiln 20, a lip brick assembly 10, and a calender 30.

[0068] It can be understood that the calendering device 1 disclosed in the present patent is applied to the calendering forming of molten materials. When the calendering device 1 works, the kiln 20 melts the raw materials to form molten materials, the molten materials flow out at the outlet of the kiln 20 to the lip brick assembly 10, form a molten pool on the lip brick assembly 10, and flow to the inlet of the calender 30 to be calendered by the calender 30, and then are cooled to form a formed material plate.

[0069] The lip brick assembly 10 is internally provided with a heating rod 120, which heats the brick body 110 of the lip brick assembly 10. The temperature difference between the upper and lower surfaces of the brick body 110 is avoided, which avoids deformation, cracking or even breaking of the lip brick caused by the temperature difference, thereby improving the service life of the lip brick assembly 10 and reducing the cost of material production.

[0070] Meanwhile, the heating rod 120 also heats the brick body 110 near the inlet of the calender 30, so that the temperature of the end part 113c of the brick body 110 is higher than the melting point of the material. In this way, the molten material is prevented from precipitating crystals in this part, which damages the calender 30, reduces the service life of the calender 30, affects the quality of the formed material, and increases the cost of manual cleaning of the material crystals.

[0071] Please refer to Figure 5 , Figure 5 is another structural schematic diagram of the calendering device 1 disclosed by the embodiments of the present disclosure. In some embodiments, the calender 30 includes two calendering rollers 31 arranged in parallel.

[0072] It can be understood that the calender 30 includes two calendering rollers 31 arranged in parallel, and the two calendering rollers 31 are driven to roll in opposite directions. The lip brick assembly 10 conveys the molten material to the gap between the two calendering rollers 31. The two calendering rollers 31 calender the molten material and cool the calendered material, thereby forming a formed material plate.

[0073] In some embodiments, the brick body 110 of the lip brick assembly 10 includes a guide part 113, and the guide part 113 has a guide slope 113a. The guide slope 113a guides the molten material to the gap between the two calendering rollers 31.

The metal support can be, but is not limited to, a steel frame, a cast iron frame, etc. The above examples of the materials of the second support 40 provided by the embodiments of the present disclosure should not be understood as a limitation of the materials of the second support 40 provided by the embodiments of the present disclosure.

[0076] It can be understood that the brick body 110 of the lip brick can include a connecting portion connected with the second support, and the connecting portion is fixedly connected with the second support 40, so as to realize the connection of the lip brick assembly 10 and the second support 40. The second support 40 can also be fixedly connected with the first support 140, so as to realize the connection of the lip brick assembly 10 and the second support 40.

[0077] Please refer again to Figure 5 In some embodiments, the calendering device 1 further comprises a transition roll table 50 located downstream of the calender 30 for cooling and forming the calendered material.

[0078] It can be understood that the transition roll table 50 located downstream of the calender 30 can realize the conveying of the calendered and formed material plate. The molten material is rapidly cooled after being calendered by the calender 30, and the rapidly cooled and formed material plate is conveyed to the annealing furnace by the transition roll table 50 for annealing. The material plate after annealing is conveyed to the cold end and then cut and packaged, so as to complete the production.
