[0022] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0023] In the present disclosure, unless otherwise indicated, the directional words used, such as "inside" and "outside", refer to the inside and outside of the corresponding parts and components. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0024] According to a specific embodiment of the present disclosure, a method for measuring the level of molten glass is provided. Figure 2 The glass liquid level measuring device shown in the figure is used to achieve this. Figure 1 and Figure 2 As shown, the method may include the following steps: emitting ionizing radiation with a dose of S1 to a melting furnace 1 filled with molten glass, receiving ionizing radiation passing through the melting furnace 1, and recording the dose of ionizing radiation received as R1; emitting ionizing radiation with a dose of S2 to a melting furnace 1 without molten glass, receiving ionizing radiation passing through the melting furnace 1, and recording the dose of ionizing radiation received as R2; when measuring the liquid level P of the molten glass in the current melting furnace 1, emitting ionizing radiation with a dose of S3 to the melting furnace 1, receiving ionizing radiation passing through the melting furnace 1, and recording the dose of ionizing radiation received as R3; by formula The liquid level P is calculated, wherein the liquid level P is the percentage of the current amount of molten glass to the amount of molten glass when the melting furnace 1 is full of molten glass. It should be noted that the dosage unit of ionizing radiation in the specific embodiments of the present disclosure is millisievert (mSv).

Therefore, by calculating (S1-R1)-(S2-R2), the ionizing radiation dose absorbed by the glass liquid part when the melting furnace 1 is full of glass liquid can be obtained. When the liquid level P of the glass liquid in the melting furnace 1 is unknown, the glass liquid level measurement method provided by the present disclosure can measure the ionizing radiation dose S3-R3 absorbed by the current glass liquid part, the melting furnace 1 itself and the air in total. By calculating (S3-R3)-(S2-R2), the ionizing radiation dose absorbed by the current glass liquid part can be obtained. The ratio of the ionizing radiation dose absorbed by the current molten glass to the ionizing radiation dose absorbed by the molten glass when the molten glass fills the melting furnace 1 can be calculated, and this ratio can reflect the ratio of the current amount of molten glass to the amount of molten glass when it is full. The percentage of the current amount of molten glass to the amount of molten glass when it is full can be calculated, that is, the liquid level P. The molten glass level measurement method provided by the present disclosure calculates the molten glass level P by detecting the change in the ionizing radiation dose passing through the melting furnace 1 and the molten glass, which can prevent the molten glass from adhering to the measuring tool in contact with it, thereby affecting the measurement accuracy of the measuring tool. In addition, it can also prevent the measuring tool from bringing impurities into the molten glass to form molten glass impurities and glass plate defects, thereby ensuring the yield rate of the glass plate.

[0026] In order to make the measured ionizing radiation dose S1-R1 absorbed by the melting furnace 1 when it is full of molten glass more accurate, the step of "emitting ionizing radiation with a dose of S1 to the melting furnace 1 full of molten glass, receiving ionizing radiation passing through the melting furnace 1, and recording the received ionizing radiation dose as R1" may include: emitting ionizing radiation with a dose of S1 to the melting furnace 1 respectively; 11 , S 12 , S 13 ionizing radiation, respectively receive the ionizing radiation passing through the melting furnace 1, and record the dose of ionizing radiation received each time as R 11 , R 12 , R 13 ; Through the formula Calculate S1 by the formula Calculate R1. S1 and R1 take the average value of the three emitted ionizing radiation doses and the three received ionizing radiation doses respectively, which can reduce the measurement error and improve the measurement accuracy.

[0027] In order to make the measured ionizing radiation dose S2-R2 absorbed by the melting furnace 1 itself and the air more accurate, the step of "emitting ionizing radiation with a dose of S2 to the melting furnace 1 without glass liquid, receiving the ionizing radiation passing through the melting furnace 1, and recording the received ionizing radiation dose as R2" may include: emitting ionizing radiation with a dose of S2 to the melting furnace 1 respectively; 21 , S 22 , S 23 ionizing radiation, respectively receive the ionizing radiation passing through the melting furnace 1, and record the dose of ionizing radiation received each time as R 21 , R 22 , R 23 ; Through the formula Calculate S2 by the formula Calculate R2. S2 and R2 take the average of the three emitted ionizing radiation doses and the three received ionizing radiation doses respectively, which can reduce the measurement error and improve the measurement accuracy.

[0028] In order to make the measured ionizing radiation dose S3-R3 absorbed by the current glass liquid part, the melting furnace 1 itself and the air more accurate, the step of "when measuring the liquid level P of the glass liquid in the current melting furnace 1, emitting ionizing radiation with a dose of S3 to the melting furnace 1, receiving ionizing radiation passing through the melting furnace 1, and recording the received ionizing radiation dose as R3" may include: emitting ionizing radiation with a dose of S3 to the melting furnace 1 respectively; 31 , S 32 , S 33 ionizing radiation, respectively receive the ionizing radiation passing through the melting furnace 1, and respectively record the dose of ionizing radiation received as R 31 , R 32 , R 33 ; Through the formula Calculate S3 using the formula Calculate R3. S3 and R3 take the average value of the three emitted ionizing radiation doses and the three received ionizing radiation doses respectively, which can reduce the measurement error and improve the measurement accuracy.

The inner wall 13 surrounds and forms a sealed cavity 11, and the glass liquid is stored in the sealed cavity 11. Among them, the inner wall 13 may be made of high-aluminum refractory bricks to improve the high temperature resistance of the melting furnace 1, the outer wall 12 is made of steel structure support materials to make the melting furnace 1 have sufficient strength and rigidity, and the insulation layer 14 may be made of porous insulation materials to reduce heat transfer between the glass liquid and the outside.

When the melting furnace 1 is a rectangular parallelepiped structure, the radial direction is the direction extending along the diagonal line of the cross section of the rectangular parallelepiped structure. When the ionizing radiation emitter 2 and the ionizing radiation receiver 3 are arranged along the radial direction of the melting furnace 1, the ionizing radiation can pass through the melting furnace 1 as much as possible, so as to improve the accuracy of the measured absorbed ionizing radiation dose.

In order to ensure the reliability of the radiation protection layer, the ionizing radiation emitter 2 may include a multi-layer steel tank layer 22. In addition, the ionizing radiation receiver 3 may be a radiation detector commonly used in the market, and the present disclosure does not limit this.

Currently, the monitoring technology for gamma rays is relatively mature, so the detected radiation dose is relatively accurate. It should be noted that the radiation source 24 may also be other suitable radiation sources, and the present disclosure does not limit this.

[0034] In addition, in order to ensure production and life safety, the method may further include: placing the melting furnace 1, the ionizing radiation emitter 2 for emitting ionizing radiation, and the ionizing radiation receiver 3 for receiving ionizing radiation in a closed space, referring to Figure 2 When the ionizing radiation emitter 2 and the ionizing radiation receiver 3 are in operation, it is also necessary to prevent workers from approaching.
