Description

Technical Field

[0001] The utility model relates to the technical field of glass furnaces, in particular to a full-electric glass furnace throat. Background Art

[0002] The throats of glass furnaces have several structural forms such as upward-tilting type, horizontal type, and downward-sinking type. However, no matter which structural form, the bottom wall of the throat is directly connected to the side wall of the rising channel, and there are dead corners in the glass liquid flow at the connection.

[0003] In the dead corner area between the bottom wall brick of the throat and the side wall brick of the rising channel, the temperature of the glass liquid is relatively low and the viscosity is relatively high. The glass liquid with relatively high viscosity will intermittently mix into the well-homogenized glass liquid, resulting in an increase in the product defect rate.

[0004] Therefore, it is necessary to provide a full-electric glass furnace throat to solve the above technical problems. Summary of the Utility Model

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a full-electric glass furnace throat which can avoid the glass liquid staying at the connection between the bottom wall and the side wall, and reduce the generation of glass product defects.

[0006] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0007] The full-electric glass furnace throat includes a descending channel, a throat, and an ascending channel. A guiding component is installed at the bottom of the throat. The guiding component includes two guiding blocks and a connecting plate. The two guiding blocks are respectively installed at the connecting corners between the throat and the descending channel and the ascending channel. The bottom of the guiding block is closely attached to the inner wall of the bottom of the throat. The connecting plate is installed between the two guiding blocks, and the bottom of the connecting plate is also closely attached to the inner wall of the bottom of the throat. The top of the connecting plate is smoothly transitioned with the arc-shaped guiding surface on the guiding block to reduce the flow resistance of the glass liquid. The embedding part of the guiding block is embedded into the inner wall of the descending channel / ascending channel, so that the top of the arc-shaped guiding surface is smoothly transitioned with the inner wall of the descending channel / ascending channel.

[0008] Preferably, a strengthening component is installed at the top of the throat.

[0009] Preferably, the strengthening component includes a first wall brick for reinforcement, a plurality of second wall bricks for reinforcement, and a cover brick.

The first clamping blocks are adapted to the first clamping grooves preset on the top of the throat.

[0010] Preferably, a lapping groove is provided on the guiding block, and a lapping head is provided at the end of the connecting plate. The lapping head is adapted to the lapping groove.

[0011] Preferably, an arc surface and a clamping groove are formed in the cover plate brick. The arc surface of the cover plate brick is beneficial to reducing the corrosion of the cover plate brick and prolonging the service life of the cover plate brick. The clamping groove is used for installing a cooling pipe, and the cooling pipe appropriately cools the cover plate brick, which is also beneficial to prolonging the service life of the cover plate brick.

[0012] Preferably, second clamping grooves are formed in both the first additional wall brick and the second additional wall brick, and second clamping blocks are installed on one side of the first additional wall brick, the second additional wall brick and the cover plate brick. The second clamping grooves are adapted to the second clamping blocks.

Detailed implementation manners

[0028] The following further illustrates the present utility model in conjunction with the accompanying drawings and embodiments. The implementation manners of the present utility model include but are not limited to the following embodiments.

[0029] Embodiment 1:

[0030] As Figure 1-8As shown in the figure, the liquid flow hole of the all-electric glass furnace provided by the present utility model is used in an all-electric heated glass furnace, and includes: a downcomer 1, a liquid flow hole 2, and a riser 3. The materials used for building the downcomer 1, the liquid flow hole 2, and the riser 3 are conventional electrofused AZS41# bricks. The upper part of the downcomer 1 is connected to the glass melting tank, and the upper part of the riser 3 is connected to the distribution channel and the feeder channel. The glass liquid melted, clarified, and homogenized in the glass melting tank descends along the downcomer 1, then passes through the liquid flow hole 2, and finally enters the distribution channel and the feeder channel along the riser 3 for subsequent processing. A flow guiding component 4 is installed at the bottom of the liquid flow hole 2, and a strengthening component 5 is installed at the top of the liquid flow hole 2. Both the flow guiding component 4 and the strengthening component 5 are built with corundum-chrome bricks 96# to improve the high-temperature performance of the upper and lower inner walls of the liquid flow hole 2, thereby increasing the service life of the liquid flow hole. In this embodiment, the flow guiding component 4 includes two flow guiding blocks 6 and a connecting plate 7. The two flow guiding blocks 6 are respectively installed at the connecting corners between the liquid flow hole 2 and the downcomer 1 and the riser 3 ( Figure 1 as shown in the figure). The bottom of the flow guiding block 6 is closely attached to the bottom inner wall of the liquid flow hole 2. The connecting plate 7 is installed between the two flow guiding blocks 6. The bottom of the connecting plate 7 is also closely attached to the bottom inner wall of the liquid flow hole 2. The top of the connecting plate 7 is smoothly transitioned with the arc-shaped flow guiding surface 8 on the flow guiding block 6 to reduce the flow resistance of the glass liquid. It should be noted that the connecting plate 7 can be designed with an integral structure or a spliced structure. The embedded part 9 of the flow guiding block 6 is embedded into the inner wall of the downcomer 1 / riser 3 to make the top of the arc-shaped flow guiding surface 8 smoothly transition with the inner wall of the downcomer 1 / riser 3 ( Figure 1 as shown in the figure), thereby reducing the flow resistance of the glass liquid. Relying on the two flow guiding blocks 6 to fill the connection dead corners between the liquid flow hole 2 and the downcomer 1 and the riser 3, the glass liquid can flow smoothly along the directions of the downcomer 1, the liquid flow hole 2, and the riser 3, avoiding the formation of a relatively low-temperature area at the connection between the bottom wall and the side wall, reducing the generation of glass liquid with a relatively high viscosity, and preventing it from mixing into the better homogenized glass liquid, thereby reducing the generation of glass product defects and improving product quality. Moreover, the transition between the arc-shaped flow guiding surface 8 and the side wall (the inner wall on the side where the downcomer 1 and the riser 3 are far away from each other) is smoother, and the resistance when the glass liquid flows in and out along the arc-shaped flow guiding surface 8 is smaller, that is, the flow resistance of the glass liquid is reduced. Under the condition that the temperature of the glass liquid remains unchanged, this structural design makes the flow of the glass liquid faster.

[0031] By providing a flow guide assembly 4 made of better high-temperature materials and disposed at the bottom of the throat 2, which includes two flow guide blocks 6 and a connecting plate 7, on the one hand, the high-temperature performance of the bottom of the throat 2 can be improved, and the service life of the throat 2 can be extended. On the other hand, by partially embedding the flow guide blocks 6 into the side walls of the channel, the arc-shaped flow guide surfaces 8 on the flow guide blocks 6 are smoothly transitioned with the side walls, resulting in less flow resistance, avoiding the retention of molten glass at the connection between the bottom wall and the side walls, forming a region with relatively low temperature, and thus reducing the generation of glass product defects.

[0032] Embodiment 2:

[0033] As Figures 2-4 shown, the flow guide block 6 is provided with a lapping groove 10, and the end of the connecting plate 7 is provided with a lapping head 11. The lapping head 11 is adapted to the lapping groove 10. During use, the lapping head 11 at the end of the connecting plate 7 is clamped into the lapping groove 10 from top to bottom, so that the connecting plate 7 is lapped with the flow guide block 6. By adopting the lapping method, it is convenient to disassemble and replace the two.

[0034] By providing the lapping groove 10 and the lapping head 11, the connecting plate 7 is lapped with the flow guide block 6, which is convenient for disassembly and replacement.

[0035] Embodiment 3:

[0036] As Figure 1 and Figures 5-8 shown, the strengthening assembly 5 includes a first wall brick 12, a plurality of second wall bricks 13 and a cover brick 14. First clamping blocks 17 are installed on the tops of the first wall brick 12, the second wall bricks 3, and the cover brick 14. The first clamping blocks 17 are adapted to first clamping grooves preset at the top of the throat 2. During use, the first clamping blocks 17 are inserted into the first clamping grooves from the side, and the first wall brick 12, the second wall bricks 13 and the cover brick 14 are sequentially connected to the top of the throat 2. Moreover, the separable strengthening assembly 5 can more easily pass through the descending channel 1 or the ascending channel 3. After the strengthening assembly 5 is corroded to a certain extent, it can be conveniently disassembled, taken out from the descending channel 1 or the ascending channel 3, and replaced.

[0037] By providing the strengthening assembly 5 including the first wall brick 12, a plurality of second wall bricks 13 and the cover brick 14, the strengthening assembly 5 can be conveniently disassembled, dispersed through the descending channel 1 or the ascending channel 3, and replaced.

[0038] Embodiment 4:

[0039] As Figure 8As shown, an arc surface 15 and a card slot 16 are provided on the cover brick 14. The arc surface 15 of the cover brick 14 is at the solid-liquid-gas three-phase interface. The structural design of the arc surface 15 enables the bubbles in the glass liquid not to stay there for a long time, thereby reducing the corrosion of the cover brick 14 and extending the service life of the cover brick 14. In addition, the card slot 16 is used to install a cooling pipe, and the cooling pipe appropriately cools the cover brick 14 to prevent accelerated aging and wear of the cover brick 14 due to long-term use at too high a temperature, thereby improving the service life of the cover brick 14.

[0040] By providing the arc surface 15 and the card slot 16 on the cover brick 14, it is beneficial to extend the service life of the cover brick 14.

[0041] Embodiment 5:

[0042] As Figures 5-8 shown, second card slots 18 are provided on both the first additional wall brick 12 and the second additional wall brick 13. Second card blocks 19 are installed on one side of the first additional wall brick 12, the second additional wall brick 13, and the cover brick 14. The second card slot 18 is adapted to the second card block 19. During use, the second card block 19 is snapped into the second card slot 18 from above, thereby facilitating the sequential connection of the first additional wall brick 12, the second additional wall brick 13, and the cover brick 14 to form a whole, with stronger stability.

[0043] By providing the second card slot 18 and the second card block 19, it is possible to conveniently connect the first additional wall brick 12, the second additional wall brick 13, and the cover brick 14 into a whole, improving the structural stability of the strengthening component 5.

[0044] Working principle: During use, the glass liquid that has been melted, clarified, and homogenized in the glass melting tank flows down along the descending channel 1. When the glass liquid flows to the arc-shaped diversion surface 8, the glass liquid smoothly turns along the arc-shaped diversion surface 8 and enters the flow hole 2. The bottom of the glass liquid flows along the connecting plate 7 to the arc-shaped diversion surface 8 on the other side, and is smoothly turned upward through the guidance of the arc-shaped diversion surface 8 and flows into the ascending channel 3. Finally, it flows into the distribution channel and the feeding channel along the ascending channel 3 for subsequent processing. By using the arc-shaped diversion surface 8, it is possible to avoid the glass liquid staying at the connection between the bottom wall and the side wall, forming a region with a relatively low temperature, thereby reducing the generation of glass product defects, and having the advantages of smaller flow resistance and facilitating the flow of the glass liquid.
