Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of float glass production, and particularly relates to a depth measuring device. Background Art
[0002] As the largest production method in the current market, float glass production has become the dominant technology for flat glass production due to its advantages such as high output, large scale, and strong continuity. The main difference in the production process of float glass from other glass production methods is the use of a tin bath for forming. During the forming process in the tin bath, if the depth of the tin liquid is too low, it will lead to an excessive climbing curve and the risk of broken plates; if the tin liquid is too deep, it will lead to a too small climbing curve and the risk of tin spots on the bottom of the plate due to tin sticking. To maintain the stability of the tin liquid depth, tin needs to be added regularly. Without accurate tin liquid depth, the amount of added tin can only be estimated based on empirical values, resulting in too high or too low tin liquid depth.
[0003] Since the environmental temperature in the tin bath is between 600°C and 1000°C, ordinary measurement methods such as depth sensors cannot meet the measurement requirements. Summary of the Utility Model
[0004] The main purpose of the utility model is to propose a depth measuring device for measuring the depth of the tin liquid in the tin bath.

[0026] Since the ambient temperature of the tin bath is between 600°C and 1000°C, ordinary measurement methods such as temperature sensors cannot meet the measurement requirements.
[0027] The present utility model proposes a depth measurement device 100 for measuring the depth of molten tin in a tin bath.
[0028] Please refer to Figure 1 , in an embodiment of the present utility model, the depth measurement device 100 includes a main body 1, a clamping portion 2, and a measurement portion 3. The clamping portion 2 is provided at one end of the main body 1; the measurement portion 3 is movably inserted into the clamping portion 2 and partially exposed outside the clamping portion 2, and the measurement portion forms an angle with the main body.
[0029] In this embodiment, the main body 1 is made of a material with high temperature resistance and good heat dissipation performance, such as stainless steel, etc. The shape of the main body 1 can be a tubular structure, and the air inside it can reduce the heat conduction performance of the main body 1, preventing damage to the main body 1 or scalding the measurement personnel operating the main body 1 due to the heat conduction of the high-temperature tin liquid. The clamping part 2 can be a clamp structure connected to one end of the main body 1, holding the measuring part 3 by both sides of the clamp to clamp and fix the measuring part 3 at one end of the main body 1. The clamping part 2 can also be a tubular structure, and the measuring part 3 directly penetrates into the tubular structure. The measuring part 3 is detachably connected to the clamping part 2. By replacing the measuring part 3, multiple measurements can be achieved, saving costs. The measuring part 3 is made of a material that does not react with the tin liquid, such as a carbon rod, etc.
[0030] The technical solution of the present utility model is that by using the clamping part 2 provided at one end of the main body 1, the measuring part 3 movably penetrates into the clamping part 2 and partially exposes outside the clamping part 2. When the measurement personnel use the depth measurement device 100, they control the main body 1 to make the measuring part 3 enter the tin bath parallel to the gap between the top cover of the tin bath and the bottom of the tin bath, and then rotate the main body 1, thereby rotating the measuring part 3, so that the part of the measuring part 3 exposed outside the clamping part 2 is inserted into the tin bath, and one end of the measuring part 3 abuts against the bottom of the tin bath. The high-temperature tin liquid will leave a physical trace on the measuring part 3. Measuring the position of this physical trace on the measuring part 3 can obtain the depth of the tin liquid in the tin bath. The depth measurement device 100 has a simple structure, can manually measure the depth of the tin liquid in the tin bath, and has simple and efficient operation, can accurately measure the depth of the tin liquid, is beneficial to maintaining the stability of the depth of the tin liquid in the tin bath, reducing the fluctuation of the depth of the tin liquid in the tin bath, reducing the risk of tin bath plate breakage, and improving the bottom quality of the tin glass plate.
[0031] In the embodiment of the present utility model, the main body 1 is a steel pipe;
[0032] And / or, the length of the main body 1 is 1500 mm - 2000 mm.
[0033] In this embodiment, a steel pipe is used as the main body 1, which has good heat dissipation performance, and the air in the steel pipe can delay the heat conduction, preventing scalding the measurement personnel during operation. The length of the main body 1 can be 1500 mm, 1600 mm, 1700 mm, 1800 mm, 1900 mm, 2000 mm or any numerical length within the above range. The specific length value can be determined according to the temperature of the tin liquid, the size of the actual site, etc., and will not be further limited here.
[0034] In the embodiment of the present utility model, the clamping part 2 is connected to the main body 1 by right-angle welding.
[0035] In this embodiment, a steel pipe is used as the clamping part 2. The material is simple and easy to obtain. The cavity inside the steel pipe can be used to thread the measuring part 3. The clamping part 2 and the main body 1 are integrally connected by right-angle welding. The welding connection strength is relatively high. Of course, it can be understood that a threaded hole can also be provided on one side of the clamping part 2, and the main body 1 and the clamping part 2 are connected by threads. The advantage of the right-angle connection between the clamping part 2 and the main body 1 is that the length from the physical trace left by the molten tin on the measuring part 3 directly to one end of the measuring part 3 can be equivalent to the depth of the molten tin in the tin bath, without the need for conversion according to the angle, improving the accuracy and speed of measurement.
[0036] In an embodiment of the present utility model, the clamping part 2 is a steel pipe, the measuring part 3 is threaded through the steel pipe, and a threaded hole is provided on the side of the clamping part 2 away from the main body 1;
[0037] The depth measuring device 100 further includes a screw member 4. One end of the screw member 4 is screwed through the threaded hole and abuts against the measuring part 3.
[0038] In this embodiment, one side of the clamping part 2 is integrally connected to the main body 1 by right-angle welding, and a threaded hole is provided on the other side. One end of the screw member 4 is screwed through the threaded hole and penetrates into the inside of the clamping part 2 to abut and fix the measuring part 3 inside the clamping part 2. Through the cooperation of the screw member 4 and the threaded hole, measuring parts 3 of different sizes can be adapted, and then the depth of the molten tin can be measured, and it is convenient to replace the new measuring part 3 for multiple measurements to obtain a more accurate depth of the molten tin, which is beneficial to maintaining the stability of the depth of the molten tin in the tin bath, reducing the fluctuation of the depth of the molten tin in the tin bath, reducing the risk of tin bath plate breakage, and improving the bottom quality of the tin glass plate.
[0039] In an embodiment of the present utility model, the center of the threaded hole is located on the extension line of the central axis of the main body 1.
[0040] In this embodiment, the center of the threaded hole is set on the extension line of the central axis of the main body 1, which can ensure that the screw member 4 penetrates into the middle position of the clamping part 2 to achieve a better effect of fixing the measuring part 3.
[0041] In an embodiment of the present utility model, a first handle is provided at one end of the screw member 4 away from the clamping part 2, and the first handle is integrally connected to the screw member 4 by right-angle welding.
[0042] In order to facilitate the measuring personnel to rotate the screw member 4 to replace and install a new measuring part 3, in this embodiment, at one end of the screw member 4 away from the clamping part 2, a first handle is integrally connected by right-angle welding. The welding connection is more stable, and the first handle connected at a right angle can be more labor-saving, reducing the physical consumption of the measuring personnel.
[0043] In an embodiment of the present utility model, the measuring part 3 is a carbon rod.
[0044] In this embodiment, a carbon rod is used as the measuring part 3, which is inexpensive, resistant to high temperatures, and does not react with the high-temperature tin liquid. The high-temperature tin liquid in the tin bath will only leave physical traces on the carbon rod, such as solidified tin. By measuring the distance between the physical traces and the measuring part 3, the depth of the tin liquid in the tin bath can be obtained.
[0045] In the embodiment of the present utility model, the length of the measuring part 3 exposed outside the clamping part 2 is 100 mm - 150 mm.
[0046] In this embodiment, the length of the measuring part 3 exposed outside the clamping part 2 can be 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, 150 mm, or any value within the above range. Specifically, the length of the measuring part 3 exposed outside the clamping part 2 can be set according to the depth of the tin liquid in the tin bath, and no further limitation is made here.
[0047] In the embodiment of the present utility model, a second handle 11 is provided at the other end of the main body 1, and the second handle 11 is welded to the other end of the main body 1 at a right angle.
[0048] In this embodiment, a second handle 11 is provided at the other end of the main body 1 away from the clamping part 2, and the second handle 11 is also welded to the main body 1 at a right angle. The welded connection has higher connection strength and is not easily damaged.

[0049] In the embodiment of the present utility model, the second handle 11, the first handle 41, and the measuring part 3 are arranged in parallel.
[0050] In this embodiment, the second handle 11, the first handle 41, and the measuring part 3 are arranged in parallel. The operator can synchronously control the direction and angle of the measuring part 3 through the second handle 11. First, insert the measuring part 3 into the gap between the top cover and the bottom trough of the tin bath, and then operate the second handle 11 to drive the measuring part 3 to rotate so that the part of the measuring part 3 exposed outside the clamping part 2 is immersed in the tin liquid. Through the physical traces of the high-temperature tin liquid on the measuring part 3, the depth of the tin liquid in the tin bath can be obtained, which is beneficial to maintaining the stability of the tin liquid depth in the tin bath, reducing the fluctuation of the tin liquid depth in the tin bath, reducing the risk of tin bath plate breakage, and improving the quality of the bottom of the tin glass plate.
