Description

Technical Field

[0001] The utility model relates to the technical field of cover glass manufacturing, and particularly relates to a measuring tool for the advancing length of a tank furnace electrode. Background Art

[0002] Cover glass, as the core outer component of touch screen technology, is also known as toughened optical glass, glass window or toughened mobile phone lens in the industry. Its application fields widely cover the diversified consumer electronics market with touch and display functions. Its delicate preparation process starts from grinding raw materials into powder, scientific proportioning, high-temperature melting, and finally shaping through forming technology.

[0003] Among the many key links in glass production, the melting process plays a crucial role. This process witnesses the transformation of the batch material into a homogeneous, bubble-free glass melt that meets the subsequent forming requirements under extremely high temperatures. The melting process is subdivided into five closely connected stages: silicate formation, glass phase generation, clarification and purification, composition homogenization, and cooling and shaping. Each stage deeply affects the progress of the next stage and jointly determines the quality of the final product.

[0004] It is particularly worth noting that the melting process is intertwined with complex physical, chemical, and physicochemical changes. These changes work together to transform the mechanical mixture of raw materials into a molten glass melt with a complex structure. At the same time, many defects in glass products often stem from subtle deviations in the melting stage. The quality of the glass melting process is closely related to the industrial quality, qualification rate, production cost, fuel consumption, and tank life of the product.

[0005] Currently, overflow high-aluminum silicon cover glass usually uses 60%-70% electrode heating and 30%-40% natural gas heating. The furnace heating electrodes have the performance characteristics of high voltage and large current loading. For example, in the tank furnace electrode cooling structure disclosed in the patent document CN220550101U, the tank furnace electrodes are generally installed on the side walls of the tank furnace. During the production process, current impact, glass melt erosion, and high-temperature scouring will all cause the loss of tin electrodes, resulting in insufficient heating power, a decrease in the furnace temperature, affecting the stability of the melting process, causing fluctuations in parameters such as the composition and temperature of the glass melt or other molten materials, and further affecting the quality and consistency of the product. It may also directly cause defects on the product surface, such as scratches and bubbles. To ensure the safe and reliable progress of production, it is generally necessary to regularly perform electrode advancement operations. However, the distance of each advancement needs to be determined by multiple manual measurements. The traditional manual measurement method not only has limited accuracy and low efficiency but also poses an electric shock risk. At the same time, during the electrode advancement process, the glass melt is squeezed, there is a risk of leakage from the electrode gap, and it is easy to cause the electrode to tilt and the gap to expand, further exacerbating the leakage of the glass melt and accelerating electrode damage.

[0006] Therefore, how to provide a measuring tool to measure the length of the electrode propulsion efficiently, accurately and safely, improve production safety, and reduce losses caused by measurement errors has become a technical problem that needs to be solved urgently by those skilled in the art currently.

Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0033] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0034] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0035] In the description of the embodiments of the present utility model, it should be noted that if terms such as "upper", "lower", "horizontal", "inner", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, or the orientations or positional relationships in which the products of the present utility model are usually placed during use, it is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated devices or elements must have specific orientations, be constructed and operated in specific orientations, and thus cannot be construed as limiting the present utility model.

[0036] In addition, when the term "horizontal" appears, it does not mean that the component is required to be absolutely horizontal, but it can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and it does not mean that the structure must be completely horizontal, but it can be slightly inclined.

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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The following further describes the present invention in detail with reference to the drawings, which is an explanation rather than a limitation of the present invention.

[0039] See Figure 1 , the installation schematic diagram of a measuring tool for the advancing length of a tank furnace electrode according to the present invention. The measuring tool 9 for the advancing length of the tank furnace electrode is located on the upper and lower sides of the electrode 11 to be measured. The upper side of the measuring tool 9 for the advancing length of the tank furnace electrode is fixed by a steel framework 15 and a clay 10, and the lower side of the measuring tool 9 for the advancing length of the tank furnace electrode is fixed by a steel framework 15 and a thread 13. The tool installation is parallel to the electrode, and the electrode size can be accurately measured through the scale.

If the high-temperature resistant hose 7 is directly connected to the compressed air pipeline 4, since the compressed air pressure provided by the compressed air pipeline 4 is relatively large, the connection will be unstable. However, through the adapter 6, the pressure can be effectively relieved to stably connect the high-temperature resistant hose 7 and the compressed air pipeline 4.

[0041] See Figure 3 and Figure 4The high-temperature insulation brick 1 is an imported fused high-zirconium brick with a length, height, and width of 500*30*120mm.

It is tangent to the inside of the slot reserved for the air duct in the high-temperature insulation brick and is used to fix the position of the air duct. The outlet of the air duct is 40mm away from the end of the high-temperature insulation brick close to the electrode's propulsion direction. The high-temperature ruler 3 is made of 310 stainless steel and is 460mm long. The zero position of the high-temperature ruler is consistent with the outlet of the air duct and is 40mm away from the end of the high-temperature insulation brick close to the electrode's propulsion direction. The high-temperature ruler is tightly attached to the high-temperature ruler slot reserved for the high-temperature insulation brick to fix the position of the high-temperature ruler.
