[0001] The present disclosure relates to the technical field of glass processing equipment, and in particular to an overflow device of a glass furnace and a glass furnace. Background Art

[0002] Overflow down-drawing is a kind of substrate glass production technology. The glass liquid flows from the front end of the overflow trough to the end of the overflow trough, overflows at the top of the overflow trough, flows down from the outer surfaces of both sides of the overflow trough, and converges at the bottom of the trough. Under the traction of the cooling clamping mechanism at both ends, the glass liquid then enters the substrate glass forming area.

Based on this, how to prevent the baffle at the end of the overflow trough from separating from the overflow trough to form a gap is a problem that technicians in this field need to consider.

[0031] The technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but in appropriate cases, the technologies, methods and equipment should be regarded as part of the specification. As mentioned in the above background technology, in the overflow process of glass liquid, in order to prevent the glass liquid from overflowing from the two ends of the overflow trough in the length direction, baffles are set at the two ends of the overflow trough in the length direction. However, due to the high temperature of the glass liquid, the overflow trough will produce thermal expansion, especially, the baffle at the end of the overflow trough will also be impacted by the flow of glass liquid, which can easily cause the baffle at the end of the overflow trough to separate from the overflow trough, so that a gap is generated between the baffle at the end and the overflow trough, causing the glass liquid to overflow from the gap and affect normal production. Based on this, the inventors of the present application provide an overflow device and a glass kiln for a glass kiln in one or more embodiments. The overflow device of the glass kiln strengthens the connection strength between the second baffle and the end of the overflow trough through a limit block, avoiding the problem of the second baffle separating from the end of the overflow trough and generating a gap. It is believed that it can solve one or more problems in the prior art.

[0032] In view of the above-mentioned technical problems, the utility model provides an overflow device for a glass kiln, such as Figure 1 and Figure 2 As shown, it includes: an overflow trough 1, the overflow trough 1 includes a front end 2 and an end 3 opposite to the front end 2; a first baffle 4, the first baffle 4 is arranged on the front end 2 to prevent the glass liquid from overflowing from the front end 2, and the first baffle 4 is connected to an injection pipe, and the injection pipe has an injection port 6 located at its end for injecting the glass liquid into the overflow trough 1; a second baffle 5, the second baffle 5 is arranged on the end 3 to prevent the glass liquid from overflowing from the end 3; a limit block 7, one end of the limit block 7 is connected to the top of the second baffle 5, and the other end is connected to the overflow trough 1 to strengthen the connection strength between the second baffle 5 and the end 3.

[0033] Specifically, the glass liquid is injected into the overflow trough 1 from the injection port 6, and flows from the front end 2 of the overflow trough 1 to the end 3 of the overflow trough 1. When the glass liquid fills the overflow trough 1, due to the blocking of the glass liquid by the first baffle 4 and the second baffle 5, the glass liquid will overflow the overflow trough 1 from both sides in the width direction of the overflow trough 1, flow through the outer wall of the overflow trough 1, and merge at the bottom of the outer side of the overflow to form a glass plate. Further, the height of the upper surface of the first baffle 4 and the second baffle 5 is higher than the height of the upper surface of the overflow trough 1. Specifically, the first baffle 4 can be connected to the front end 2 of the overflow trough 1 by welding, and the second baffle 5 can also be connected to the end 3 of the overflow trough 1 by welding. At the same time, the connection strength between the second baffle 5 and the end 3 of the overflow trough 1 is further strengthened by the stop block 7, avoiding the problem of the second baffle 5 and the end 3 of the overflow trough 1 being separated and forming a gap due to the thermal expansion of the overflow trough 1 and the impact of the glass melt. Further, the stop block 7 should have a certain tensile strength and tearing strength.

[0034] Compared with the prior art, the overflow device of a glass kiln in the present application strengthens the connection strength between the second baffle plate 5 and the end 3 of the overflow trough 1 by means of a limit block 7, thereby avoiding the problem of the second baffle plate 5 being separated from the end 3 of the overflow trough 1 and causing a gap due to thermal expansion of the overflow trough 1 and impact of the glass liquid.

[0035] In some embodiments, Figure 1 and Figure 2 As shown, the overflow device further includes a diverter plate 8, which is disposed in the overflow trough 1 near the end 3 to divert the glass liquid to both sides of the overflow trough 1, and the other end of the limit block 7 is connected to the diverter plate 8. The diverter plate 8 can divert the glass liquid to both sides of the overflow trough 1, and the diverter plate 8 facilitates the connection between the limit block 7 and the overflow trough 1.

[0036] In some embodiments, Figure 5 As shown, a first slot 9 is provided on one end of the limit block 7, and a second slot 10 is provided on the other end. The top end of the second baffle 5 is arranged in the first slot 9, and the diverter plate 8 is clamped in the second slot 10. The connection between the limit block 7 and the second baffle 5, and between the limit block 7 and the diverter plate 8 is realized through the first slot 9 and the second slot 10. Specifically, after the diverter plate 8 is clamped in the second slot 10, the limit block 7 can be fixed on the diverter plate 8 by passing a bolt through a bolt hole 14 provided on the top wall of the second slot 10.

[0037] In some embodiments, Figure 1-Figure 4 As shown, the overflow device also includes a temperature-averaging plate 11, which is arranged on the end 3 and has a certain distance from the second baffle 5, so as to form a barrier to the bulge 12 generated by the second baffle 5 to prevent the bulge 12 from rupturing. The temperature-averaging plate 11 is closer to the outside of the overflow device than the second baffle 5. When the second baffle 5 generates a bulge 12 under high temperature, the temperature-averaging plate 11 blocks and protects the second baffle 5 in a bulging state, thereby preventing the second baffle 5 from further swelling and rupture. Furthermore, the temperature-averaging plate 11 and the overflow trough 1 must have sufficient connection strength, and the temperature-averaging plate 11 itself must have sufficient strength and rigidity to resist the lateral thrust of the bulge 12 of the second baffle 5 on the temperature-averaging plate 11.

[0038] In some embodiments, Figure 4 As shown, a partition 13 is provided on one side of the temperature averaging plate 11 close to the second baffle plate 5 to prevent the temperature averaging plate 11 from contacting the second baffle plate 5. Specifically, the partition 13 is made of a material that does not react with the second baffle plate 5 and the temperature averaging plate 11, and under high temperature conditions, the bulge 12 of the second baffle plate 5 is prevented from directly contacting the temperature averaging plate 11 to corrode the second baffle plate 5, thereby causing leakage on the second baffle plate 5.

[0039] In some embodiments, the overflow device further includes a connecting plate (not shown in the figure), one end of the connecting plate is connected to the side wall of the second baffle 5, the other end is connected to the outer wall of the overflow tank 1, and the top of the connecting plate is connected to the limit block 7. The connection strength between the second baffle 5 and the overflow tank 1 is further strengthened by the connecting plate.

[0040] In some embodiments, the depth of the overflow trough 1 gradually decreases from the front end 2 to the end 3. By gradually reducing the depth of the trough, it is ensured that the glass liquid flows from the front end 2 to the end 3, so that the glass also overflows from both sides of the overflow trough 1 in the width direction to form a glass plate.

[0041] In some embodiments, a cooling pipe (not shown in the figure) is provided in the side wall of the overflow tank 1 to cool the overflow tank 1. The cooling pipe can cool the overflow tank 1, thereby reducing the thermal expansion of the overflow tank 1, thereby reducing the risk of a gap between the second baffle 5 and the overflow tank 1.

[0042] In some embodiments, the cooling pipe includes a plurality of cooling pipes, and the plurality of cooling pipes are evenly distributed in the side wall of the overflow tank 1. The cooling effect of the overflow tank 1 is further improved by the plurality of cooling pipes.

[0043] In addition, the utility model also provides a glass kiln, comprising the overflow device of the glass kiln mentioned above.

[0044] In summary, compared with the prior art, the present disclosure provides an overflow device and a glass kiln for a glass kiln, wherein the overflow device strengthens the connection strength between the second baffle plate 5 and the end 3 of the overflow trough 1 through the limit block 7, thereby avoiding the problem of the second baffle plate 5 being separated from the end 3 of the overflow trough 1 and causing a gap due to thermal expansion of the overflow trough 1 and impact of the glass liquid; the connection between the limit block 7 and the second baffle plate 5 and the diverter plate 8 is achieved through the first card slot 9 and the second card slot 10; the second baffle plate 5 is protected by the temperature equalizing plate 11 and the partition 13; and the thermal expansion of the overflow trough 1 is reduced by the cooling pipe.
