[0032] The technology, methods and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the technology, methods and devices should be considered as part of the specification.

[0033] As shown in Figures 1-6 The present application provides a float glass flow channel structure, comprising: a flow channel 1, the flow channel 1 is used for connecting a melting furnace and a tin bath; a shutter 2, the shutter 2 can be inserted into the flow channel 1 to control the cross-sectional area of the flow channel 1 for the glass liquid flow; wherein, a first groove 101 extending along the insertion direction is arranged on the contact surface of the flow channel 1 and the shutter 2, and a first flange 201 capable of sealingly fitting with the first groove 101 is arranged on the shutter 2.

[0034] Specifically, in the production of float glass, the glass liquid in a molten state in the flow channel 1 continuously flows from the direction of the kiln to the direction of the tin bath, the shutter 2 is vertically arranged on the flow channel 1 along the flow direction of the glass liquid, and the cross-sectional area of the flow channel 1 for the glass liquid flow is adjusted by lifting the shutter 2 by the staff. As shown in Figure 1 and Figure 2 As shown in the drawings, the first grooves 101 are arranged on the two sides of the flow channel 1 in contact with the shutter 2, and the corresponding first flanges 201 are respectively arranged on the two sides of the shutter 2, and the non-through buffer gap is formed by the sealing cooperation of the first grooves 101 and the first flanges 201, which effectively reduces the phenomenon that the glass liquid seeps into the tin bath from the gap between the flow channel 1 and the shutter 2.

[0035] As shown in Figure 2As shown in the drawings, in some embodiments, the cross sections of the first groove 101 and the first flange 201 are both arc-shaped, and the buffer gap formed by the two is a curve that changes uniformly, which is convenient for processing and is conducive to uniform heat dissipation of the glass liquid inside the buffer gap. In other embodiments, a more complex staggered structure (such as a multi-layer stepped gap) can be formed between the first groove 101 and the first flange 201 to enhance the blocking effect of the glass liquid in the buffer gap.

[0036] As shown in the drawings, Figure 2 In some embodiments, the first flange 201 is covered with a high-temperature-resistant gasket 208.

[0037] Specifically, the high-temperature-resistant gasket 208 is covered on the surface of the first flange 201 that forms a sealing fit with the first groove 101, further sealing the gap and absorbing the thermal expansion difference between the flow channel 1 and the dam 2. The high-temperature-resistant gasket 208 here can adopt graphite fiber gasket or ceramic fiber gasket, etc. with good high-temperature-resistant performance and chemical stability. In other embodiments, a high-temperature-resistant gasket 208 can also be covered on the surface of the first groove 101 that is used for sealing fit.

[0038] As shown in the drawings, Figure 1 , Figure 3 , Figure 5 and Figure 6 In some embodiments, the flow channel 1 includes a flow channel bottom brick 102, a flow channel side brick 103, and a flow channel cover brick 104, wherein the first groove 101 is arranged on the side of the flow channel side brick 103 facing the glass liquid, and the flow channel cover brick 104 is provided with an opening for the dam 2 to insert into the flow channel 1.

[0039] Specifically, as shown in the drawings, Figure 3 Generally, the flow channel 1 is composed of the horizontally placed flow channel bottom brick 102, the two columns of flow channel side bricks 103 vertically placed on the flow channel bottom brick 102, and the flow channel cover brick 104 horizontally placed above the two columns of flow channel side bricks 103, forming a flow channel 1 with a rectangular flow cross section. The dam 2 is inserted into the flow channel 1 along the vertical direction through the opening on the flow channel cover brick 104, adjusts the cross-sectional area of the flow channel 1 for the glass liquid to flow through, so that the glass liquid in the flow channel 1 can only pass from below the dam 2. During the insertion process, the sealing fit between the first groove 101 on the flow channel side brick 103 and the first flange 201 on the dam 2 forms a non-straight-through buffer gap, reducing the amount of glass liquid passing through the gap between the flow channel 1 and the dam 2.

[0040] As shown in the drawings, Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the top of the flow channel cover brick 104 is provided with a second groove 105, and the damper 2 includes a vertical part 202 for inserting into the flow channel 1 and a horizontal part 203 capable of being placed on the flow channel cover brick 104; wherein the horizontal part 203 is provided with a second flange 204 capable of forming a clamping fit with the second groove 105.

[0041] Specifically, in the float glass production process, the damper 2 is usually partially inserted into the flow channel 1 to form the required cross-sectional area inside the flow channel 1, and if necessary, the damper 2 can be completely lowered to block the flow of glass liquid inside the flow channel 1. When the damper 2 is partially inserted into the flow channel 1, the second flange 204 at the bottom of the horizontal part 203 is partially embedded in the second groove 105 in the vertical direction, which can stabilize the damper 2 under the impact of the glass liquid on one side, and on the other hand, it can improve the sealing between the damper 2 and the flow channel cover brick 104, reduce the heat loss from the top of the flow channel 1, and maintain the uniform temperature inside the flow channel 1. As shown in Figure 6 As shown, in an emergency, the damper 2 is completely lowered, and the second groove 105 and the second flange 204 are completely clamped, which further enhances the installation stability of the damper 2 on the flow channel 1, so that the damper 2 can be stably placed on the flow channel 1 under the pressure of the glass liquid on one side, meeting the emergency demand.

[0042] As shown in Figure 4 , Figure 5 and Figure 6 In some embodiments, the bottom end of the vertical part 202 is provided with a rounded corner 205. Specifically, the rounded corner 205 provided at the bottom of the vertical part 202 can effectively reduce the impact of the glass liquid passing below the damper 2 on the damper 2, prolonging the service life of the damper 2.

[0043] As shown in Figure 1 , Figure 2 and Figure 3 In some embodiments, the flow channel structure further includes a heating assembly 3 for heating the glass liquid in the flow channel 1 close to the damper 2.

[0044] Specifically, the glass liquid in the flow channel 1 needs to maintain uniform temperature when passing through the dam 2 into the tin bath to avoid uneven flow of the glass liquid and cause quality problems of the glass product. Since there is a temperature difference between the surface of the dam 2 and the glass liquid, and the flow channel 1 is provided with the first groove 101 on the flow channel side brick 103 and the opening on the flow channel cover brick 104 at the dam 2, compared with other parts in the flow channel 1, the heat loss near the dam 2 is larger, which is easy to cause the temperature of the glass liquid at this position to be uneven. The glass liquid near the dam 2 in the flow channel 1 is heated by the heating assembly 3, which can effectively avoid the phenomenon of uneven temperature of the glass liquid and avoid causing uneven flow, and improve the quality of the glass product. The heating assembly 3 here can adopt a resistance heater or a quartz heater arranged near the dam 2 in the flow channel 1.

[0045] As shown in Figures 1-4 , in some embodiments, the dam 2 is provided with a first heater mounting hole 206, and the flow channel side brick 103 and the flow channel cover brick 104 are provided with a second heater mounting hole 106; the heating assembly 3 includes a first heating pipe 301 mounted in the first heater mounting hole 206 and a second heating pipe 302 mounted in the second heater mounting hole 106.

[0046] Specifically, as shown in Figure 3 , the dam 2 is distributed with a plurality of first heater mounting holes 206 extending in the vertical direction and parallel to each other, and the flow channel 1 is provided with a second heater mounting hole 106 penetrating the flow channel cover brick 104 in the vertical direction and extending into the flow channel side brick 103, and the second heater mounting hole 106 is arranged near the dam 2 to heat the glass liquid near the dam 2. The first heating pipe 301 heats the dam 2 itself to reduce the temperature difference between the surface of the dam 2 and the glass liquid, and the second heating pipe 302 heats the body of the flow channel 1 to make up for the heat loss. Through the cooperation of the first heating pipe 301 inside the dam 2 and the second heating pipe 302 inside the body of the flow channel 1, the temperature of the glass liquid flowing through the dam 2 is adjusted to ensure uniform temperature and improve product quality. The first heating pipe 301 and the second heating pipe 302 here can adopt common heaters such as quartz heating pipes or stainless steel heating pipes. In other embodiments, under the premise of ensuring uniform heating, the first heater mounting hole 206 and the second heater mounting hole 106 can also be arranged in other forms inside the dam 2 and the flow channel 1, and the utility model is not limited.

[0047] As shown in Figure 1 and Figure 3 , in some embodiments, the outer periphery of the flow channel 1 is provided with a flow channel heat preservation brick 4.

[0048] Specifically, the flow channel heat preservation bricks 4 wrapped around the outer periphery of the flow channel 1 mainly play a role of heat preservation and insulation, and can effectively reduce the heat loss of the glass liquid in the flow channel 1, so as to ensure the flowability and forming quality of the glass liquid. The flow channel heat preservation bricks 4 here can adopt high-temperature-resistant bricks such as mullite bricks and corundum bricks.

[0049] As shown in Figure 1 and Figure 3 , in some embodiments, the outer periphery of the flow channel heat preservation bricks 4 is wrapped with a flow channel steel shell 5.

[0050] Specifically, the flow channel steel shell 5 is a metal shell wrapped around the outer periphery of the flow channel heat preservation bricks 4, and mainly plays a role of supporting and protecting the structure of the flow channel 1, for bearing the internal pressure of the flow channel 1 and external mechanical load, and ensuring the stability and safety of the flow channel structure. At the same time, the flow channel steel shell 5 can also prevent the glass liquid from leaking, so as to protect the safety of the operating personnel and equipment. The flow channel steel shell 5 here can adopt metal materials such as carbon steel or stainless steel.

[0051] As shown in Figure 1 , Figure 2 and Figure 4 , in some embodiments, the top of the dam plate 2 is provided with a lifting screw hole 207 for connecting a lifting device. Specifically, the lifting screw hole 207 is a mounting hole with threads on the inner surface, and the operating personnel rotates a lifting screw provided with a connecting piece into the lifting screw hole 207, and then connects the lifting device with the connecting piece, so as to drive the dam plate 2 to ascend and descend, and facilitate the operating personnel to control the dam plate 2 to ascend and descend to adjust the cross-sectional area that can flow in the flow channel 1.
