The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The edge drawing machine is the core forming equipment of float glass production. The edge drawing machine has the functions of throttling, thinning and accumulating thickness, stabilizing the plate root and controlling the width of glass. Specifically, the edge drawing machine includes the edge drawing machine head and the joystick. The forming of float glass depends on the traction of the edge drawing machine head. The edge drawing machine head pulls the glass ribbon forward on the tin liquid surface. By adjusting the parameters such as the rotation speed of the edge drawing machine head, the horizontal angle of the joystick, and the depth of the joystick pressing into the glass ribbon, the width and thickness of the glass ribbon can be controlled.

[0028] During the glass production process, tin spots, tin points and optical deformation points will affect the quality of glass production. By increasing the tin bath release to discharge pollutants in the tin bath, the impact on glass production quality can be reduced to a certain extent. In order to further improve glass quality and glass production efficiency, it is necessary to further increase the tin bath release, improve the pollutant emission level and emission capacity, and reduce the impact of pollutants on glass quality.

[0029] Reference below Figure 1-Figure 2A connection device 100 according to an embodiment of the present invention is described.

[0030] like Figure 1 As shown, the connecting device 100 according to the embodiment of the utility model includes a pipeline 1 and an exhaust pipe 2.

[0031] The pipe 1 has a first end 101 and a second end 102. The first end 101 is sealed and connected to the tin bath, and the second end 102 is connected to the edge drawing machine, which can move relative to the second end 102 of the pipe 1. A hollow cavity is formed in the pipe 1, and the hollow cavity can accommodate the edge drawing machine. An exhaust pipe 2 is fixed on the pipe wall of the pipe 1, and the exhaust pipe 2 is connected to the hollow cavity. The exhaust port 202 of the exhaust pipe 2 is detachably connected to a sealed end cap (not shown in the figure).

[0032] When the edge drawing machine is working, the machine head and a part of the operating rod of the edge drawing machine move in the hollow cavity and extend into the tin bath, pulling the glass ribbon forward on the tin liquid surface in the tin bath. The other part of the operating rod is located outside the tin bath. The edge drawing rod and the tin bath are connected by the connecting device 100, which can improve the quality of glass production.

[0033] In glass production, the tin bath needs to be maintained within the bath pressure control index. When the pressure in the tin bath is less than the bath pressure control index, the exhaust port 202 is connected to the sealing end cap to reduce the release of the tin bath, increase the bath pressure, and achieve normal glass production. Therefore, by detachably connecting the sealing end cap to the exhaust port 202, the release of the tin bath can be controlled, and the controllability of glass production can be improved.

[0034] When the tin bath is within the bath pressure control index, the sealing end cap can be detached from the exhaust pipe 2, allowing the connecting device 100 to effectively discharge pollutants through the exhaust pipe 2, reducing the condensation of pollutants in the connecting device 100, and improving the quality of glass production; timely discharge of pollutants through the exhaust pipe 2 can reduce the frequency of cleaning and improve production efficiency.

[0035] According to the connecting device 100 of the embodiment of the utility model, on the one hand, a good seal between the edge drawing machine and the tin bath can be achieved. On the other hand, the pollutants in the tin bath inside the connecting device 100 can be discharged, the glass quality is improved, the cleaning frequency is reduced, and the production efficiency is improved. This device mainly realizes the sealing and dispersion of the connecting device 100 by opening and closing the exhaust port 202. When the exhaust port 202 is separated from the sealing end cap, the pollutants in the tin bath can be effectively discharged to prevent the pollutants from condensing in the connecting device 100 to form tin spots, tin spots or optical deformation points that affect the glass quality, thereby improving the glass quality; the use of the connecting device 100 can also discharge pollutants in time, reduce the cleaning frequency, improve efficiency and output, and reduce costs.

[0036] like Figure 1As shown, in some embodiments, the exhaust port 202 of the exhaust pipe 2 is higher than the air inlet 201 of the exhaust pipe 2. When in use, the pressure in the tin tank squeezes the pollutants such as tin vapor to the exhaust port 202 of the exhaust pipe 2. Due to the concentration difference between the tin tank and the external space, air is easily mixed into the tin tank. By making the exhaust port 202 higher than the air inlet 201 of the exhaust pipe 2, it is helpful to reduce the probability of air entering the tin tank, thereby improving the quality of glass production.

[0037] In some examples, the air inlet 201 of the exhaust pipe 2 is fixed on the pipe wall of the pipeline 1, and the air inlet 201 is connected to the hollow cavity. The exhaust pipe 2 has an ascending section and a descending section, wherein the ascending height of the ascending section is greater than the descending height of the descending section, so that the exhaust port 202 is higher than the air inlet 201.

[0038] In some other examples, the exhaust pipe 2 has a plurality of rising sections so that the exhaust port 202 is higher than the air inlet 201 .

[0039] like Figure 1 As shown, in some embodiments, the exhaust pipe 2 includes an exhaust valve 3, which is detachably connected to the exhaust port 202. By setting the exhaust valve 3, the gas flow rate can be adjusted, and the opening of the exhaust valve 3 can be appropriately adjusted according to the tank pressure control index, so that the tank pressure is maintained within the tank pressure control index, so that the connecting device 100 can effectively discharge pollutants through the exhaust pipe 2. When it is necessary to stop the discharge of the connecting device 100, the exhaust valve 3 is slowly closed to maintain the tank pressure within the tank pressure control index; the exhaust valve 3 can also be disassembled from the exhaust pipe 2 and sealed with a sealing end cap. By setting the exhaust valve 3, the degree of discharge can be adjusted to improve the controllability of the exhaust pipe 2, thereby improving the controllability of glass production and the ability to control glass production.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, there are multiple exhaust pipes 2, and the multiple exhaust pipes 2 are spaced apart on the pipe wall of the pipeline 1, thereby improving the emission capacity of the connecting device 100, further improving the efficiency of the connecting device 100 in emitting pollutants, and further improving the production quality and production efficiency.

[0041] like Figure 1 and Figure 2As shown, in some embodiments, the exhaust pipe 2 includes a first exhaust section 21 and a second exhaust section 22. One end of the first exhaust section 21 is fixed to the pipeline 1, and the other end of the first exhaust section 21 is detachably connected to the exhaust valve 3. The other end of the first exhaust section 21 is an exhaust port 202. The second exhaust section 22 is connected to the exhaust end of the exhaust valve 3. The first exhaust section 21 is extended in the horizontal direction, and the second exhaust section 22 is extended in the vertical direction. The first exhaust section 21 is fixed to the pipeline 1. When the first exhaust section 21 is matched with the sealing end cap, the sealing performance and sealing reliability are higher. The second exhaust section 22 and the exhaust valve 3 are detachably connected to the first exhaust section 21. The exhaust valve 3 may not be tightly closed after long-term use. The second exhaust section 22 and the exhaust valve 3 can be removed from the first exhaust section 21, and the other end of the first exhaust section 21 is sealed by the sealing end cap, which can reduce the influence of the exhaust valve 3 not being tightly closed on the tin bath pressure, thereby further improving the controllability of glass production and the ability to control glass production.

[0042] like Figure 1-Figure 2 As shown, specifically, the first exhaust section 21 extends from the pipe wall of the pipeline 1 in a direction away from the center of the pipeline 1, and the first exhaust section 21 is a release fixed end. The end of the first exhaust section 21 has an external thread, and the exhaust valve 3 is fixed to the end of the first exhaust section 21 through the external thread, so that the opening can be freely adjusted; the second exhaust section 22 is a release free end, which can be extended according to the actual situation on site to improve the release capacity.

[0043] like Figure 1 As shown, in some embodiments, the exhaust valve 3 has an adjustment handle 31. By providing the adjustment handle 31, manual operation of the exhaust valve 3 is facilitated.

[0044] like Figure 1-Figure 2 As shown, in some embodiments, the pipeline 1 includes a corrugated pipe section 12 and a straight pipe section 11, and the straight pipe section 11 is connected to the corrugated pipe section 12. The exhaust pipe 2 is sealed and connected to the straight pipe section 11. The corrugated pipe section 12 can be extended and bent, and the joystick of the edge drawing machine is fixed on the pipeline 1. The horizontal angle of the joystick and the depth of the joystick pressed into the glass ribbon are adjusted by the deformation of the corrugated pipe, so that the joystick drives the edge drawing machine head to move. By sealingly connecting the exhaust pipe 2 to the straight pipe section 11, the reliability and stability of the connection between the exhaust pipe 2 and the straight pipe section 11 are improved.

[0045] For example, the exhaust pipe 2 is welded to the straight pipe section 11 .

[0046] In some embodiments, there are multiple bellows sections 12, and the straight pipe section 11 is disposed between two adjacent bellows sections 12, so as to further improve the flexibility of deformation of the pipeline 1, thereby improving the flexibility of the joystick operation.

[0047] like Figure 1-Figure 2As shown, for example, the pipeline 1 includes a straight pipe section 11 and two bellows sections 12, one end of one bellows section 12 is sealed and connected to the tin bath, the other end of one bellows section 12 is connected to one end of the straight pipe section 11, the other end of the straight pipe section 11 is connected to one end of another bellows section 12, and one end of the other bellows section 12 is provided with a drawing machine sealing structure 13 and is sealed and connected to the operating rod.

[0048] In some embodiments, the edge drawing machine sealing structure 13 is embedded with multiple graphite rings, and a joystick can be inserted and installed in the middle of the multiple graphite rings. Each graphite ring matches the radial size of the joystick, and the joystick is inserted into the middle of the graphite ring for sealing installation. The contact surface between the graphite ring and the edge drawing machine rod is a semicircular arc surface, which can reduce friction.

[0049] like Figure 1-Figure 2 As shown, in some embodiments, the edge of the first end 101 is provided with a flange 14 extending away from the center direction of the pipe 1, and the flange 14 is fixed to the tin bath by fasteners. When in use, the edge drawing machine is inserted into the tin bath and the position of the connecting device 100 is adjusted so that the flange 14 is connected to the tin bath, and the fasteners are used to quickly lock it.

[0050] Specifically, after the edge drawing machine is extended into the tin bath, the position of the connecting device 100 is adjusted so that the flange 14 is butted against the edge seal of the tin bath, and a T-shaped screw is used for rapid locking.

[0051] Other structures and operations of the connection device 100 according to the embodiment of the utility model are known to those skilled in the art and will not be described in detail here. In the description of the utility model, "first feature" and "second feature" may include one or more of these features.
