DETAILED DESCRIPTION

[0022] The molten furnace overflow port lip brick device of the steel mould shell body includes lip brick frame 1 and lip brick assembly 2 (see description attached Figure 1 ).

[0023] Lip brick frame 1 includes support pipe frame 9, link plate 14, link screw 15, positioning plate 10 and limiting screw 13 (see description attached Figure 3).

[0024] The upper end of the support pipe frame 9 is provided with a positioning plate 10 on one side, and an assembly screw is assembled through an assembly hole 11 (not shown in the drawings). Figure 1 ).

[0025] The support pipe frame 9 on both sides of the positioning plate 10 is provided with a limiting screw 13 through a limiting seat 12 (see the drawings Figure 3 and 4 ). The purpose of setting the limiting screw 13 is that the transverse position of the limiting screw 13 can be adjusted by rotating during assembly, so that the transverse position of the lip brick assembly 2 can be positioned by adjusting the position of the limiting screw 13.

[0026] The lower part of the end of the support pipe frame 9 is provided with a connecting plate 14; the connecting plate 14 is provided with a plurality of connecting screws 15 (see the drawings Figure 3 and 4 ). During assembly, the support pipe frame 9 can be fixed to the overflow port position of the glass melting furnace through the connecting plate 14 and the connecting screw 15.

[0027] One end of the support pipe frame 9 is provided with a cooling water inlet joint 16; the other end of the support pipe frame 9 is provided with a cooling water outlet joint 17. During work, the support pipe frame 9 can be continuously supplied with cooling water through the cooling water inlet joint 16 and the cooling water outlet joint 17, so as to avoid the problem of bending and deformation of the support pipe frame 9 due to the high temperature of the glass melting furnace.

[0028] A plurality of lip brick assemblies 2 are continuously assembled on the lip brick frame 1 (see the drawings Figure 1 and 2 ). Ceramic fiber cotton is inserted between the lip brick assemblies 2 (not shown in the drawings). The purpose of inserting ceramic fiber cotton between the lip brick assemblies 2 is to fill the gap between the lip brick assemblies 2 with ceramic fiber cotton, so as to avoid the problem of glass liquid leakage between the lip brick assemblies 2.

[0029] The lip brick assembly 2 includes a steel mold shell 3, a positioning pin 6 and an inner lip brick 4 (see the drawings Figure 6 and 7 ).

[0030] The upper end of the steel mold shell 3 is horizontally structured, and the lower end is provided with an assembly stepped opening 7 on one side; the other side of the steel mold shell 3 is provided with an assembly open mouth 8 (see the drawings Figure 7 ). The lip brick assembly 2 can be installed on the lip brick frame 1 under the action of the assembly stepped opening 7 and the positioning plate 10.

[0031] When working, the glass liquid can enter into the subsequent upper and lower calender rollers under the guidance of the upper end plane of the steel mold shell body 3 to complete the production of the glass ribbon.

[0032] The inner lip brick 4 is installed in the steel mold shell body 3 through the assembly of the open mouth 8. The inner lip brick 4 is tightly fitted with the inner wall of the steel mold shell body 3 by refractory mortar (see the attached drawings of the specification Figure 6 ). The purpose of installing the inner lip brick 4 in the steel mold shell body 3 is that, due to the fast heat transfer characteristics of the steel mold shell body 3, when the glass liquid flows through the steel mold shell body 3, the heat of the lower layer of glass liquid will be quickly discharged through the steel mold shell body 3 to cause the freezing of the lower layer of glass liquid and affect the production. After the inner lip brick 4 is installed in the steel mold shell body 3, the inner lip brick 4 can utilize its own heat preservation characteristics to avoid the heat dissipation of the steel mold shell body 3 to cause the freezing of the glass liquid.

[0033] The upper end and the lower end of the steel mold shell body 3 are provided with a plurality of positioning through holes 5; the inner lip brick 4 corresponding to the positioning through holes 5 is provided with a positioning counterbore; the positioning counterbore and the corresponding positioning through hole 5 are fitted with a positioning pin 6 (see the attached drawings of the specification Figure 5 、 6 and 8). The purpose of setting the positioning pin 6 is to position and fix the inner lip brick 4 installed in the steel mold shell body 3 through the positioning pin 6 to avoid the mispositioning of the inner lip brick 4.

[0034] The steel mold shell body 3 is made of 2080 heat-resistant steel. Since the 2080 heat-resistant steel has the characteristics of high temperature resistance and wear resistance, when the steel mold shell body 3 is made of the 2080 heat-resistant steel, it can not only avoid the deformation of the steel mold shell body 3 under the action of the high temperature of the glass melting furnace, but also solve the problem of easy wear of the existing lip brick device.

[0035] The overflow port lip brick device of the glass melting furnace with the steel mold shell body 3 has a compact structure and a clever design, solves the problem of easy wear of the existing lip brick by utilizing the characteristics of high temperature resistance and wear resistance of the steel mold shell body 3, and is particularly suitable for the needs of glass production.
