TECHNICAL FIELD

[0001] The present application relates to the technical field of glass production, and particularly relates to a manual liquid level measuring device for a glass melting furnace. BACKGROUND

[0002] In the glass production process, the liquid level height of the glass in the glass melting furnace is always a key indicator, and the accuracy of the measurement plays a decisive role in the quality of the glass product and the production efficiency. At present, the measurement of the liquid level height of the glass melting furnace mainly adopts image type liquid level meter, laser liquid level meter, platinum probe type liquid level meter and other means. These liquid level meters usually need to be debugged and used under the condition that the glass liquid level is relatively stable. However, during the hot charging stage of the glass melting furnace, the glass liquid level in the melting furnace continues to rise, and at this time, the above-mentioned commonly used liquid level meters cannot play a role. In this case, the method commonly used in the industry is to use an L-shaped iron hook. The specific operation is to insert the L-shaped iron hook into the glass liquid level, take it out after the iron hook is stable in the glass liquid, and then measure the length of the part of the iron hook not immersed in the glass by using a ruler to determine the liquid level height. However, this method has many disadvantages: from the safety point of view, the temperature in the glass melting furnace is extremely high, and the operator needs to insert the L-shaped iron hook into the melting furnace at close range, which exposes them to a high-temperature environment and makes them vulnerable to serious injuries such as burns, posing a great safety hazard; in terms of measurement accuracy, this measurement method has a large error and is difficult to accurately distinguish millimeter-level changes in the liquid level. The precision of the liquid level height is quite high in glass production, and millimeter-level errors can significantly affect the quality of the final product. SUMMARY

[0003] In view of this, in order to solve the above problems, the purpose of the present application is to provide a manual liquid level measuring device for a glass melting furnace, which comprises: a long rod part and a short rod part, the short rod part is connected with one end of the long rod part, the short rod part and the long rod part are vertically arranged, and a scale groove is formed on the short rod part.

[0004] In another preferred embodiment, the scale groove comprises: a plurality of arc-shaped grooves and a plurality of ring-shaped grooves, the plurality of arc-shaped grooves and the plurality of ring-shaped grooves are uniformly arranged along the vertical direction, and the arc-shaped grooves and the ring-shaped grooves are arranged in a staggered manner along the vertical direction.

[0005] In another preferred embodiment, the two adjacent arc-shaped grooves are arranged in a staggered manner along the circumference of the short rod part.

[0006] In another preferred embodiment, a plurality of arc-shaped grooves are arranged between the two adjacent ring-shaped grooves.

[0007] In another preferred embodiment, the other end of the long rod part is provided with a handle.

[0008] In another preferred embodiment, a mounting hole is formed on the handle, and the other end of the long rod part extends into the mounting hole.

[0009] In another preferred embodiment, a heat-resistant glue coating is arranged on the inner wall of the mounting hole, and the other end of the long rod part is bonded to the handle through the heat-resistant glue coating.

[0015] It should be particularly pointed out that "horizontal" and "vertical" in the present application are used to illustrate the approximate positional relationship, rather than the strict "horizontal plane" or "vertical plane".

[0016] As Figs. 1-3 shown, the artificial liquid level measuring device for glass melting furnace of a preferred embodiment comprises a long rod part 1 and a short rod part 2, the short rod part 2 is connected with one end of the long rod part 1, the short rod part 2 is vertically arranged with the long rod part 1, and a scale groove is formed on the short rod part 2.

[0017] Further, as a preferred embodiment, the scale groove comprises a plurality of arc grooves 21 and a plurality of ring grooves 22, the plurality of arc grooves 21 and the plurality of ring grooves 22 are uniformly arranged along the vertical direction, and the arc grooves 21 and the ring grooves 22 are arranged in a staggered manner along the vertical direction.

[0018] Further, as a preferred embodiment, the arc grooves 21 are arranged in a semicircular shape.

[0019] Further, as a preferred embodiment, the two adjacent arc grooves 21 are arranged in a staggered manner along the circumference of the short rod part 2, which is conducive to increasing the fineness of the scale, so that the operator can more accurately read the position of the glass liquid on the short rod part 2.

[0020] Further, as a preferred embodiment, a plurality of arc grooves 21 are arranged between the two adjacent ring grooves 22.

[0021] Further, as a preferred embodiment, the distance between the two adjacent ring grooves 22 is preferably 10mm, and the distance between the two adjacent arc grooves 21 is preferably 1mm. Further, the ring grooves 22 and the arc grooves 21 are used as scale lines.

[0022] Further, as a preferred embodiment, the other end of the long rod part 1 is provided with a handle 3.

[0023] Further, as a preferred embodiment, the handle 3 is preferably made of hard wood, such as beech, oak, etc. Further, the handle 3 not only has good heat insulation performance, but also is convenient to hold and operate, so that the operator's hands are more comfortable during long-time operation, which is conducive to reducing the fatigue of the operator's hands, further improving the operation experience of the operator, and ensuring that the measurement work can be carried out efficiently and stably.

[0024] Further, as a preferred embodiment, a mounting hole is formed on the handle 3, and the other end of the long rod part 1 extends into the mounting hole.

[0025] Further, as a preferred embodiment, a heat-resistant adhesive coating is arranged on the inner wall of the mounting hole, and the other end of the long rod part 1 is bonded to the handle 3 through the heat-resistant adhesive coating.

[0026] The working principle of this invention is as follows: During use, the operator can hold the handle 3 and vertically insert the short rod 2 into the glass melting furnace. This vertical insertion ensures that the short rod 2 is in vertical contact with the glass melt surface, thus making the measurement result more accurately reflect the liquid level height. Then, the operator can place the long rod 1 horizontally on the upper surface of the glass melting furnace, making the long rod 1 parallel to the liquid surface of the glass melt in the glass melting furnace, and maintain this static state for 5s-10s to ensure that the short rod 2 can fully contact the glass melt in the glass melting furnace. The glass melt can form a clear wetting boundary on the short rod 2. Then, holding the handle 3, the operator can remove the short rod 2 from the glass melt and place it aside for a period of time to wait for the glass melt on the short rod 2 to cool and solidify. At this time, the position of the glass melt on the short rod 2 has become stable. The operator can read the scale value corresponding to the area covered by the glass melt, and then combine it with the vertical height of the upper surface of the glass melting furnace. Subtracting the vertical height of the upper surface of the glass melting furnace from the scale value corresponding to the area covered by the glass melt will give the height of the glass melt surface.

[0027] Inserting the short rod: The operator holds handle 103 and vertically inserts the short rod 102 into the neck of the melting furnace. Vertical insertion ensures that the short rod is in perpendicular contact with the molten glass surface, resulting in a more accurate measurement of the liquid level.

[0028] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
