Description

Technical Field

[0001] The utility model relates to the field of float glass production and manufacturing, in particular to a detection device, a tin bath system and a glass production system. Background Art

[0002] The forming of float glass is mainly completed in a tin bath, and the tin liquid in the tin bath is extremely easy to oxidize. In order to prevent the oxidation of the tin liquid, the method adopted is to introduce protective gas (N2 and H2) into the tin bath. Moreover, the purity and water content of the protective gas play a vital role in the surface defects of float glass.

[0003] By detecting the dew point of the tin bath, we can observe the relationship between trace oxygen, hydrogen and trace water in the tin bath protective gas, and judge whether the tin bath is well sealed and whether there is leakage in the water-using equipment in the tin bath.

[0004] At present, when testing the dew point of the tin bath, the sampling port is to chisel out the sealing mud and sealing cotton between the side seals of the tin bath and then insert the sampling tube into the tin bath for testing. When opening the sampling port, the tin bath will inevitably vibrate, causing SnO2 and SnO condensed in the tin bath to fall onto the glass plate surface due to the vibration. In addition, when the sampling tube is inserted into the tin bath, the sealing mud and sealing cotton around the sampling port are easily brought into the tin bath, contaminating the tin bath and affecting the quality of the glass. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a detection device, which aims to solve the problems in the prior art that the tin bath system easily affects the quality of the produced float glass when detecting the dew point inside the tin bath system, and has low efficiency and complex structure.

[0006] To achieve the above-mentioned purpose, the technical solution adopted in this application is to provide a detection device, characterized in that it includes:

[0007] Edge seal, used to seal the tin bath;

[0008] A detection pipeline is provided, wherein the detection pipeline passes through the edge seal along the width direction of the tin bath and extends to the top of the tin bath; a valve is provided at one end of the detection pipeline away from the tin bath.

[0009] Optionally, the edge seal includes an edge seal box body, and an edge seal limiting frame is provided on the periphery of one end of the edge seal box body away from the tin bath, for abutting against a step provided on the edge of the tin bath to limit the position.

[0011] Optionally, a handle is provided on a side of the edge seal limiting frame away from the edge seal box body.

[0012] Compared with existing technologies:

[0013] The detection device provided by the utility model is provided with an edge seal and a detection pipe which runs through the edge seal box and can be controlled to open and close by a valve. The edge seal can be installed in the tin bath system to seal the tin bath. When it is necessary to detect the dew point of the tin bath, the valve can be opened, and a detection catheter for detecting the dew point condition inside the tin bath can be inserted from the detection pipe into the interior of the tin bath to detect the dew point condition inside the tin bath. When it is not necessary to detect the dew point of the tin bath, the detection catheter can be withdrawn from the detection pipe, the valve can be closed, and the tin bath system can be sealed. Therefore, when the dew point of the tin bath is detected, there is no need to chisel open the sealing mud and sealing cotton between the edge seals of the tin bath, so as to avoid vibration of the tin bath, which causes SnO2, SnO, etc. condensed in the tin bath to fall onto the glass plate surface due to the vibration, and the sealing mud and sealing cotton around the sampling port will not be brought into the tin bath to contaminate the tin bath and affect the quality of the glass.

[0038] See also Figures 1 to 3 This embodiment provides a detection device, including: an edge seal 100 for sealing the tin bath; a detection pipe 20, the detection pipe 20 passes through the edge seal 100 along the width direction of the tin bath 40 and extends to the top of the tin bath 40; a valve 21 is provided at one end of the detection pipe 20 away from the tin bath 40.

[0039] When implementing it specifically, Figure 1 and Figure 2As shown, the left side of the edge seal 100 is its first end 12, and the right side is its second end 13. A detection pipe 20 extends from the first end 12 to the second end 13 of the edge seal 100. A valve 21 is provided at the end of the detection pipe 20 located at the first end 12 of the edge seal 100. In this application, the valve 20 is in the open state to allow the detection pipe 20 to pass through, allowing the detection conduit of the dew point detection device to be inserted from the detection pipe 20 to the outside of the second end 13 of the edge seal 100. The valve 20 is in the closed state to block the detection pipe 20, preventing the detection conduit of the dew point detection device from being inserted into the detection pipe 20. The edge seal 100 can seal the tin bath system to ensure the smooth operation of the float glass production process. Specifically, how the dew point detection device detects the relationship between trace oxygen, hydrogen, and trace water in the tin bath protective gas to determine whether the tin bath is properly sealed and whether there are any leaks in the water-using equipment in the tin bath is prior art and will not be further described here. During the float glass production process, this embodiment is set in the tin bath. When the dew point in the tin bath needs to be detected, the valve is opened, and then the detection conduit of the dew point detection device is inserted from the detection pipe 20 and enters the outside of the second end 13 of the side seal 100 from the first end 11. The detection conduit is located above the tin bath 40, so that the dew point can be detected. When the dew point in the tin bath does not need to be detected, the detection conduit of the dew point detection device is withdrawn from the detection conduit 20 and the valve 21 is closed, so that the tin bath 40 can be sealed.

[0040] Preferably, if Figure 1 As shown: the detection pipe 20 in this embodiment is a stainless steel pipe, and the valve 21 is a stainless steel ball valve; one end of the detection pipe 20 is provided with an external thread, and the detection pipe 20 is connected to the stainless steel ball valve by a threaded connection.

[0041] Compared with existing technologies:

[0042] The detection device provided by the utility model is provided with an edge seal and a detection pipe which runs through the edge seal box and can be controlled to open and close by a valve. The edge seal can be installed in the tin bath system to seal the tin bath. When it is necessary to detect the dew point of the tin bath, the valve can be opened, and a detection catheter for detecting the dew point condition inside the tin bath can be inserted from the detection pipe into the interior of the tin bath to detect the dew point condition inside the tin bath. When it is not necessary to detect the dew point of the tin bath, the detection catheter can be withdrawn from the detection pipe, the valve can be closed, and the tin bath system can be sealed. Therefore, when the dew point of the tin bath is detected, there is no need to chisel open the sealing mud and sealing cotton between the edge seals of the tin bath, so as to avoid vibration of the tin bath, which causes SnO2, SnO, etc. condensed in the tin bath to fall onto the glass plate surface due to the vibration, and the sealing mud and sealing cotton around the sampling port will not be brought into the tin bath to contaminate the tin bath and affect the quality of the glass.

[0043] Preferably, the edge seal 100 includes an edge seal box 10 , and an edge seal limiting frame 31 is provided on the periphery of one end of the edge seal box 10 away from the tin bath 40 , for abutting against a step provided on the edge of the tin bath 40 to limit the position.

[0044] In specific applications, such as Figure 2 As shown, the edge seal 100 includes an edge seal housing 10 and an edge seal limiting frame 31. The edge seal limiting frame 31 is located at the first end 12 of the edge seal 100, i.e., the first end 12 of the edge seal housing 10. When the edge seal 100 is installed in the tin bath, the edge seal limiting frame 31 can limit the position to avoid operating errors and push the edge seal 100 into the tin bath. On the other hand, the detection pipe 20 can be extended to a position suitable for detecting dew point defects. Preferably, the edge seal housing 100 has a rectangular parallelepiped or cubic structure. The two sides of the edge seal limiting frame 31 in the width direction are flush with the edge seal housing 100, and the two sides of the edge seal limiting frame 31 in the height direction extend outward of the two edges of the edge seal housing 10 in the height direction.

A detection pipe 20 is also provided through at least one of the edge seals. During float glass production, molten tin is located at the bottom of the tin bath. A protective gas, such as N2 and / or H2, is contained between a top cover 41 and the tin bath 40. When the edge seal is installed in the tin bath system, the detection pipe 20 extends into the space containing the protective gas. When the dew point inside the tin bath 40 needs to be tested, a detection conduit for testing the dew point inside the tin bath can be passed from the outside of the tin bath 40 into the tin bath 40 through the detection pipe to test the dew point. When testing is no longer necessary or has been completed, the detection conduit can be removed from the detection pipe 20 and the valve 21 closed to seal and insulate the tin bath system. Preferably, detection devices can be provided on opposite sides of the tin bath 40.

[0052] Preferably, the detection pipe 20 is placed horizontally. After the valve 21 is opened, the detection tube for detecting the dew point inside the tin bath is inserted into the detection pipe 20 without touching the glass or the tin liquid, thereby avoiding affecting the quality of the glass.
