Specific embodiments
[0018] Referring to Figures 1 to 5 As shown, the present utility model provides a device for discharging materials at the bottom of a substrate glass furnace, comprising: a furnace body 1 and a sealing assembly 10. Feeding ports 2 and throat pipes 3 are respectively arranged at both end faces of the furnace body 1. The lower surface of the furnace body 1 is fixedly connected to the CZ brick layer 9, and the lower surface of the CZ brick layer 9 is fixedly connected to the alumina brick layer 8. The lower surface of the alumina brick layer 8 is fixedly connected to the mullite brick layer 7, and the mullite brick layer 7 is fixedly connected to the insulating board 5 through the thick furnace bottom plate 6. The lower surface of the insulating board 5 is symmetrically connected to the secondary beam 4, and the lower surface of the secondary beam 4 is fixedly connected to the sealing assembly 10. The sealing assembly 10 is composed of a support frame 11, a pressing support plate 15, a pushing screw rod 16 and a plug member 19. The plug member 19 is fixedly connected in the fitting groove through the high-temperature resistant sealing cotton 12. Fitting grooves are respectively arranged in the middle of the insulating board 5, the thick furnace bottom plate 6 and the mullite brick layer 7. The lower surface of the plug member 19 is movably connected to the pushing screw rod 16 through a bearing. The lower end of the pushing screw rod 16 is screwed to the pressing support plate 15. At the same time, the pressing support plate contacts the support frame 11 through the insulating block 14. The support frame 11 is fixedly connected to the lower surface of the secondary beam 4. The lower surface of the plug member 19 is respectively connected to the water inlet pipe 17 and the water return pipe 18. Partition plates 21, heat conducting blocks 23 and heat conducting plates 22 are respectively fixedly connected inside the plug member 19.
[0019] In this embodiment, during the daily operation of the tank furnace body 1, the radiant temperature of the secondary beam 4 located below the refractory layer at the bottom of the tank is 120 - 200 °C. When the valve of the water inlet pipe 17 in the plugging component 10 is opened, through the cooperation of the water inlet pipe 17 and the water return pipe 18, 2 megawatts of pure water will be introduced into the plugging piece 19 for cooling circulation. The plugging piece 19 can perform corresponding cooling on the surrounding area, so that the molten glass accumulated in the discharge holes opened in the alumina brick layer 8 and the CZ brick layer 9 can be cooled and solidified to ensure a good plugging effect. When the tank furnace body 1 needs cold repair and discharging, first rotate the propulsion screw rod 16. The propulsion screw rod 16 pushes the screwed insulating block 14 and the top - tight support plate 15 to move upward synchronously, releasing the restriction on the symmetrical plugging pieces 19 between the top - tight support plate 15 and the support frame 11. Then, the plugging pieces 19 and the high - temperature resistant plugging cotton 12 can be removed from the refractory layer at the bottom of the tank, so that the fitting grooves and the discharge holes opened in the insulating plate 5, the thick tank bottom plate 6 and the mullite brick layer 7 can be directly exposed to the outside. After that, under the action of an external discharging gun (not shown in the figure), the discharge holes opened in the alumina brick layer 8 and the CZ brick layer 9 can be burned through, and the solidified glass in the discharge holes will turn back into molten glass. Therefore, the high - temperature molten glass inside the tank furnace body 1 can be safely discharged completely.
[0020] As a preferred embodiment, the plugging piece 19 has a cylindrical structure, and the inside of the plugging piece 19 is hollow. The outer diameter of the plugging piece 19 is 98 mm, and the axial length is 290 mm. The upper surface of the plugging piece 19 abuts against the lower surface of the alumina brick layer 8. At the same time, the high - temperature resistant plugging cotton 12 fixedly connected to the outer side surface of the plugging piece 19 has a cylindrical structure.
[0021] In this embodiment, as Figure 2 、 Figure 3 and Figure 4 show, the setting of the high - temperature resistant plugging cotton 12 can assist in enhancing the high - temperature resistance effect of the plugging piece 19. At the same time, the upper surface of the plugging piece 19 abuts against the lower surface of the alumina brick layer 8. Then, the upper surface of the plugging piece 19 can plug the discharge hole opened in the alumina brick layer 8, thereby reducing the probability of accidental leakage of the molten glass inside the tank furnace body 1.
[0022] As a preferred embodiment, the plugging piece 19 is composed of a shell 20 and a partition plate 21. Six groups of heat - conducting plates 22 are fixedly connected to the inner side surface of the shell 20 at equal intervals along the circumferential direction. The six groups of heat - conducting plates 22 are all in a long - strip structure, and the end face of the heat - conducting plate 22 is in an isosceles trapezoid structure. The through - hole opened inside the heat - conducting plate 22 has a cylindrical structure.
[0023] In this embodiment, as Figure 4 and Figure 5, the setting of the guiding plate and the through hole can effectively increase the cooling area inside the housing 20, and then can assist in enhancing the heat exchange effect when pure water flows inside the housing 20, thereby enhancing the cooling effect of the housing 20 on the outside environment.
[0024] As a preferred embodiment, the partition plate 21 is in a rectangular structure, the partition plate 21 is fixedly connected in the installation groove opened on the side of the housing 20, the sizes of the partition plate 21 and the installation groove are adapted to each other, and the inner cavity of the housing 20 forms a U-shaped structure through the partition plate 21. A plurality of heat conducting blocks 23 are uniformly and fixedly connected to the top of the inner cavity of the housing 20, and the heat conducting blocks 23 are in a hemispherical structure.
[0025] In this embodiment, as shown in Figure 4 and Figure 5 , the setting of the partition plate 21 enables the pure water to only flow along a specific route inside the housing 20, and then can assist in enhancing the heat exchange efficiency of the pure water inside the housing 20, ensuring that cold water flows in and hot water flows out. At the same time, the setting of the heat conducting blocks 23 can further enhance the cooling efficiency of the pure water on the upper surface of the housing 20, enabling the plugging member 19 to quickly cool down the glass liquid inside the discharge hole, so that the glass liquid solidifies to block the discharge hole, thereby avoiding the problem of accidental leakage of the glass liquid in the tank furnace body 1.
[0026] As a preferred embodiment, the insulating plate 5 is made of quartz material, the thickness of the insulating plate 5 is 25 mm, the thick pool bottom plate 6 fixedly connected to the upper surface of the insulating plate 5 is made of stainless steel material, the thickness of the mullite brick layer 7 laid on the upper surface of the thick pool bottom plate 6 is 175 mm, the thickness of the alumina brick layer 8 fixedly connected to the upper surface of the mullite brick layer 7 is 150 mm, the thickness of the CZ brick layer 9 fixedly connected to the upper surface of the alumina brick layer 8 is 75 mm, and the insulating plate 5, the thick pool bottom plate 6, the mullite brick layer 7, the alumina brick layer 8 and the CZ brick layer 9 are combined together to form the bottom refractory layer of the pool.
[0027] In this embodiment, as shown in Figure 1 and Figure 2 , the setting of the bottom refractory layer enables the bottom of the tank furnace body 1 to have good high-temperature resistance and insulation effects, and then can assist in enhancing the safety during the discharging process of the tank furnace body 1.
[0028] As a preferred embodiment, a plurality of secondary beams 4 are fixedly connected to the lower surface of the insulating plate 5 in parallel at equal intervals. The plurality of secondary beams 4 are all made of I-beams, and the insulating plate 5 and the secondary beams 4 are combined together to form an E-shaped structure. At the same time, discharge holes are correspondingly opened at the positions of the alumina brick layer 8 and the CZ brick layer 9 opposite to the fitting grooves, and the diameter of the discharge holes is 35 mm.
[0029] In this embodiment, as shown in Figure 1 and Figure 2, the diameter of the discharge hole is smaller than the diameter of the plug member 19, so that the plug member 19 can successfully block the discharge hole, thereby assisting in enhancing the blocking effect of the blocking assembly 10 on the discharge hole and reducing the probability of accidental leakage of the raw materials inside the tank furnace body 1.
[0030] As a preferred embodiment, two secondary beams 4 near the fitting groove below the insulating plate 5 are fixedly connected to a set of support frames 11. The two support frames 11 are both in an L-shaped structure, and the tensioning support plate 15 slidably connected between the two support frames 11 is in a rectangular structure. The insulating block 14 fixedly connected to the lower surface of the tensioning support plate 15 is in a square structure. Both ends of the insulating block 14 are symmetrically connected with channel-shaped retaining pieces 13. At the same time, the insulating block 14 and the channel-shaped retaining pieces 13 are combined to form a convex-shaped structure.

The tensioning support plate 15 is screwed to the advancing screw rod 16 through the nut, and the insulating block 14 is screwed to the advancing screw rod 16 through the screwed holes opened. At the same time, the two channel-shaped retaining pieces 13 symmetrically arranged on both sides of the insulating block 14 can cooperate with the support frame 11 to limit the moving range of the insulating block 14 and enhance the stability of the insulating block 14 and the tensioning support plate 15 during movement. And through the cooperation of the support frame 11, the advancing screw rod 16, the tensioning support plate 15 and the insulating block 14, it can assist in enhancing the firmness of the fixed connection of the plug member 19 inside the bottom refractory layer of the tank.
[0032] The bottom discharge device of the substrate glass tank furnace of the present utility model, through the cooperation of the bottom refractory layer and the blocking assembly 10, makes the fixation between the discharge device and the tank furnace body 1 accurate and reliable, and can enhance the cooling effect of the blocking assembly 10, extend the service life of the discharge device, and when discharging treatment is required, it can also be operated conveniently, improve the discharge efficiency, and at the same time enhance the safety during the discharging process.
