Description

Technical Field

[0001] This utility model relates to the field of glass production equipment technology, and in particular to a liquid level measuring tool. Background Technology

[0002] In the glass substrate production process, molten glass, after being heated to a high temperature, is supplied to the forming equipment through a platinum channel. The liquid level of the molten glass within the platinum channel has a significant impact on the forming of the glass substrate, directly affecting its quality, such as stress and warpage. Therefore, in addition to automatic measurement of the liquid level, manual measurement is also required during the glass substrate production process to check and confirm the liquid level of the molten glass within the platinum channel.

[0003] Existing manual liquid level measurement tools typically use a measuring needle. After opening the liquid level detection hole in the platinum channel, the measuring needle is inserted into the platinum channel through the detection hole to measure the liquid level height. Because the temperature inside the platinum channel is high, and the measuring needle lacks protective components, the operator's arm handling the needle is exposed to a high-temperature environment for extended periods, posing a risk of burns and other safety hazards. Furthermore, external impurities can easily enter the platinum channel through the open liquid level detection hole, contaminating the molten glass inside. In addition, heat from within the platinum channel can escape to the outside through the liquid level detection hole, reducing the stability of the internal temperature environment.

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] In the glass substrate production process, in addition to automatic liquid level measurement, manual measurement is also required to check and confirm the liquid level of the molten glass in the platinum channel. Existing manual liquid level measurement tools typically use a measuring needle. After opening the liquid level detection hole in the platinum channel, the measuring needle is inserted into the platinum channel through the detection hole to measure the liquid level height. Because the temperature inside the platinum channel is high, and the measuring needle lacks protective components, the operator's arm holding the needle is exposed to a high-temperature environment for extended periods, posing a risk of burns and other safety hazards. Furthermore, external impurities can easily enter the platinum channel through the open liquid level detection hole, contaminating the molten glass inside. In addition, heat from within the platinum channel can also escape to the outside through the liquid level detection hole, reducing the stability of the ambient temperature within the platinum channel.

[0032] To solve the above problems, such as Figure 1 and Figure 2 As shown, the liquid level measuring tool includes a measuring needle 1 and a protective plate 2. The measuring needle 1 is configured to pass through a liquid level detection hole in a platinum channel, with its first axial end extending into the platinum channel to detect the liquid level height within the channel. The protective plate 2 includes a cover plate 21 and a plug 22, with the plug 22 located on one side of the cover plate 21. The protective plate 2 is fitted over the second axial end of the measuring needle 1. The cover plate 21 covers the liquid level detection hole, and the plug 22 seals and embeds within the liquid level detection hole. When the measuring needle 1 detects the liquid level height in the platinum channel through the liquid level detection hole, the measuring needle 1 passes through the liquid level detection hole in the platinum channel, with its first axial end extending into the platinum channel to detect the liquid level height. The cover plate 21 of the protective plate 2 is positioned above the liquid level detection hole, and the plug 22 of the protective plate 2 is embedded in the liquid level detection hole. This seals the liquid level detection hole during liquid level measurement, not only blocking heat from the platinum channel and preventing burns to personnel, thus improving safety for both personnel and the measurement process, but also preventing heat loss through the liquid level detection hole, ensuring temperature stability within the platinum channel. Furthermore, the protective plate 2 prevents impurities from entering the platinum channel through the liquid level detection hole, avoiding contamination of the molten glass within the platinum channel.

[0033] Specifically, after the first axial end of the measuring needle 1 is inserted into the platinum channel, the first end of the measuring needle 1 can be immersed in the molten glass. After the measuring needle 1 has been left to stand for a period of time, it is pulled out from the liquid level detection hole. Then, the axial length of the molten glass surrounding the first end of the measuring needle 1 is measured using a measuring tool (ruler, etc.), thereby obtaining the liquid level height of the molten glass in the platinum channel. Since measuring the liquid level height of the molten glass in the platinum channel using the measuring needle 1 is existing technology, the specific measurement process will not be described in detail.

[0034] It should be noted that the circumferential side of the first end of the measuring needle 1 is provided with graduation lines along the axial direction. By setting graduation lines, the axial length of the molten glass surrounding the first end of the measuring needle 1 can be directly read through the graduation values ​​of the graduation lines, improving measurement efficiency. In this embodiment, the measuring needle 1 is a platinum needle, that is, the measuring needle 1 is made of the same material as the platinum channel, so that the measuring needle 1 has good high-temperature resistance, thereby achieving reliable measurement of the molten glass, while not being deformed or damaged by the high temperature of the molten glass, avoiding contamination of the molten glass, and ensuring the safety of the measurement process. In other embodiments, the measuring needle 1 can also be made of other high-temperature resistant materials, as long as it is ensured that the measuring needle 1 will not deform or be damaged during liquid level measurement and will not contaminate the molten glass; no specific limitation is made here.

[0035] In this embodiment, the cover plate 21 and the plug 22 are integrally formed, making the protective plate 2 easier to manufacture and reducing its cost. Both the cover plate 21 and the plug 22 are circular plates, with the plug 22 coaxially protruding from one side of the cover plate 21, giving the protective plate 2 a stepped surface surrounding the plug 22. When the measuring needle 1 is inserted into the liquid level detection hole of the platinum channel, the plug 22 is embedded in the liquid level detection hole, and the stepped surface abuts against the end face of the platinum channel where the liquid level detection hole is located, thus achieving the limited installation of the liquid level measuring tool in the liquid level detection hole.

[0036] It should be noted that the protective plate 2 is a platinum plate, meaning that the protective plate 2 is made of the same material as the platinum channel. This ensures that the protective plate 2 has good high-temperature resistance, preventing deformation or damage from the high temperature of the molten glass and avoiding contamination of the molten glass. In other embodiments, the protective plate 2 can also be made of other high-temperature resistant materials, as long as it does not deform or damage during level measurement and does not contaminate the molten glass; no specific limitations are imposed here.

[0037] like Figure 1 and Figure 2As shown, the liquid level measuring tool also includes a locking nut 3. A limiting part 11 is provided at the second end of the measuring needle 1. A protective plate 2 is sleeved on the measuring needle 1. The locking nut 3 is threadedly connected to the measuring needle 1 and presses against the plug 22, so that the cover plate 21 abuts against the limiting part 11. The protective plate 2 is securely assembled to the second end of the measuring needle 1 by the locking nut 3, improving the assembly strength and disassembly efficiency of the protective plate 2 and the measuring needle 1.

[0038] In an optional embodiment, the liquid level measuring tool further includes a gasket 4, which is fitted onto the measuring needle 1 and clamped between the locking nut 3 and the plug 22. The gasket 4 disperses the pressure exerted by the locking nut 3 on the protective plate 2, ensuring that the protective plate 2 is subjected to uniform force and preventing damage to the protective plate 2 caused by the locking nut 3.

[0039] like Figure 1 and Figure 2 As shown, the liquid level measuring tool also includes a handle 5, which is connected to the second end of the measuring needle 1. The handle 5 allows the operator to easily hold the tool and quickly pick it up and put it away.

[0040] Specifically, the handle 5 includes a first rod 51 and a second rod 52. One end of the first rod 51 is connected to the second end of the measuring needle 1. The other end of the first rod 51 is integrally connected to the second rod 52 in an L-shape. This design makes the handle 5 L-shaped, improving its structural strength. Simultaneously, the operator only needs to hold the second rod 52 to pick up the liquid level measuring tool. The first rod 51 separates the operator's hand from the protective plate 2, preventing contact between the operator's hand and the heated protective plate 2. Furthermore, the extended length of the handle 5 reduces heat conduction to the second rod 52, resulting in a lower temperature rise in the second rod 52 and further reducing the risk of burns to the operator's hand.

[0041] It should be noted that the handle 5 is a stainless steel handle, which is welded to the second end of the measuring needle 1. The stainless steel handle has good structural strength, low cost, and is easy to weld.
