Description

Technical Field

[0001] The present disclosure relates to the technical field of glass furnace monitoring, and in particular to a device for measuring the thickness of a glass furnace pool wall. Background Art

[0002] The service life of the pool wall in the glass melting furnace is an important factor that determines the stable operation of the entire glass production line. Therefore, daily monitoring and maintenance of the pool wall tiles is a very important task, and understanding the residual thickness of the pool wall tiles after being eroded by the glass liquid is the top priority in the daily monitoring of the pool wall tiles. However, since the inner side of the pool wall tiles is inside the glass melting furnace and is in direct contact with the glass liquid, the temperature is extremely high. In the past, it was impossible to measure its residual thickness. The thickness of the pool wall tiles was judged based on experience by observing the pool wall tiles from the outside of the pool wall tiles to see whether they were "red" and "shiny" in depth, and then the pool wall was maintained by "increasing the cooling air volume", "tying bricks", "externally attaching cooling water bags" and other maintenance work.

[0003] However, the residual thickness of the pool wall tiles observed from the outside is affected by the experience of the observer and has a large error. It is often impossible to perform maintenance work such as "brick tying" and "external water-removing bags" at the most appropriate thickness due to inaccurate judgment of the thickness of the residual pool wall tiles, which affects the overall service life of the kiln.

[0004] In this regard, Chinese invention patent CN102538734A discloses a glass kiln pool wall brick erosion detection system, which installs a K-type thermocouple on the interface between the middle backing brick and the inner dense brick, detects the cold surface temperature of the inner dense brick, and converts the cold surface temperature parameter into the thickness of the inner dense brick according to the stable heat conduction heat transfer calculation formula. This detection method requires a complex control system, is costly, and is easily affected by the kiln ambient temperature and the pool wall cooling air volume, resulting in deviations in the measurement results.

It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such herein.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] Combination Figure 1 and Figure 2 As shown, the glass furnace pool wall thickness measuring device provided by the embodiment of the present disclosure includes a first measuring rod 1 and a second measuring rod 2.

[0032] The first measuring rod 1 has a measuring portion 11 that can extend through the gap in the pool wall 3 into the furnace pool and can be supported on the inner side of the pool wall 3, and a measuring needle 12 is provided on the first measuring rod 1. Specifically, the measuring portion 11 is provided at the end of the first measuring rod 1, and the measuring portion 11 and the end of the first measuring rod 1 can extend through the gap in the pool wall 3 into the furnace pool, and by rotating and pulling back the first measuring rod 1, the measuring portion 11 can be supported at the position to be measured on the inner side of the pool wall 3.

[0033] The second measuring rod 2 is slidably arranged on the first measuring rod 1 along the extension direction of the first measuring rod 1, and the second measuring rod 2 is parallel to the first measuring rod 1. A scale plate 21 is arranged on the second measuring rod 2, and the measuring needle 12 points to the scale plate 21. Specifically, the second measuring rod 2 can move along its length direction relative to the first measuring rod 1, so that the second measuring rod 2 can be supported on the outside of the pool wall 3, and the scale of the end of the second measuring rod 2 facing the pool wall 3 is zero.

[0034] Combination Figure 1 and Figure 2 As shown, since the distance between the measuring part 11 and the measuring needle 12 is unchanged and is a fixed value L, during measurement, the measuring part 11 is supported on the inner side of the pool wall 3, and the end of the second measuring rod 2 is supported on the outer side of the pool wall 3. At this time, the measuring part 11 and the end of the second measuring rod 2 are in the same vertical plane, and the distance ΔL between the measuring part 11 and the end of the second measuring rod 2 is the wall thickness of the pool wall 3 at that position. The reading of the measuring needle 12 pointing to the measuring disk is the distance L1 between the outer side of the pool wall 3 and the measuring needle 12. At this time, ΔL=L-L1, and the wall thickness can be obtained.

[0035] Among them, when measuring, it is necessary to open the gap brick between the pool wall 3 and the hook brick. If the gap between the hook brick and the pool wall 3 brick is small, in order to facilitate the smooth entry of the measuring device into the kiln, the measuring device can be turned over as a whole to be horizontal and enter, and then quickly turned back 90° after entering the kiln.

[0036] When the measuring device provided by the present invention is used, the measuring part 11 is extended into the furnace pool, and the measuring part 11 is supported on the inner side of the pool wall 3, and then the second measuring rod 2 is adjusted so that the end of the second measuring rod 2 is supported on the outer side of the pool wall 3, and then the thickness of the pool wall 3 is obtained according to the reading of the dial 21 pointed by the measuring needle 12. This measuring device adopts a mechanical measurement structure with low cost and is not affected by other external factors to avoid affecting the measurement results. It can truly and accurately react to the thickness of the pool wall 3 to obtain the erosion condition of the pool wall 3, and can accurately maintain the corroded position of the pool wall 3 to ensure the service life of the kiln.

[0037] In some embodiments, Figure 1 As shown, the measuring part 11 includes a measuring hook 111 arranged at the end of the first measuring rod 1 , one end of the measuring hook 111 is connected to the end of the first measuring rod 1 , and the other end of the measuring hook 111 is used to be supported on the inner side of the pool wall 3 .

[0038] In this design, the end of the measuring hook 111 and the inner side of the pool wall 3 adopt a point contact method, which can better support the measurement of the specific position of the inner wall of the pool wall 3 to increase the accuracy of the measurement.

[0039] In some embodiments, the measuring hook 111 includes a movable hook 1111 perpendicular to the first measuring rod 1 and a support hook 1112 arranged at the end of the movable hook 1111. The distance of the movable hook 1111 along its length direction can be adjusted, and the support hook 1112 is used to support the inner side of the pool wall 3.

[0040] In this design, a movable hook 1111 with adjustable length is used so that the movable hook 1111 can support the supporting hook 1112 at multiple positions, thereby increasing the measuring range.

[0041] In some embodiments, the extension direction of the support hook 1112 is perpendicular to the extension direction of the movable hook 1111, so that during the pullback process of the first measuring rod 1, the end of the support hook 1112 can be stably supported on the inner side of the pool wall 3, avoiding slippage between the support hook 1112 and the pool wall 3, thereby ensuring the stability of positioning.

[0042] In some embodiments, a sleeve 13 extends vertically from the end of the first measuring rod 1 , and the movable hook 1111 slidably cooperates with the sleeve 13 . The sleeve 13 is provided with an adjusting member 14 for adjusting the length of the movable hook 1111 extending into the sleeve 13 .

[0043] In this design, the length of the movable hook 1111 extending out of the sliding sleeve 13 can be adjusted through the sliding cooperation between the movable hook 1111 and the sliding sleeve 13, so that the support hook 1112 can be supported at a preset position to meet the position adjustment requirements of the support hook 1112.

[0044] In some embodiments, the adjusting member 14 includes an adjusting screw 141 passing through the sleeve 13 along the extension direction of the sleeve 13 , and a first adjusting nut 142 arranged on the sleeve 13 and matching the adjusting screw 141 , and the end of the adjusting screw 141 is connected to the movable hook 1111 .

[0045] Under this design, during adjustment, by rotating the adjusting screw 141, under the action of the first adjusting nut 142, the adjusting screw 141 will move along its own length direction to drive the movable hook 1111 to move along the length direction of the adjusting screw 141, thereby increasing the convenience of adjusting the movable hook 1111.

[0046] During use, when it is necessary to measure the erosion thickness of the pool wall 3, the screw 141 is adjusted to adjust the depth of the measuring hook 111 (the position of the supporting hook 1112) so that the measuring hook 111 can hook the corroded part on the inner side of the pool wall 3. By adjusting the second measuring rod 2 to make it horizontally against the outer side of the pool wall 3, the position indicated by the measuring needle 12 is observed.

[0047] In some embodiments, a first gripping portion 16 is provided at one end of the first measuring rod 1 away from the measuring portion 11 .

[0048] In this design, by providing the first gripping portion 16 , it is possible to increase the convenience for the staff to hold the first measuring rod 1 .

[0049] In some embodiments, the first holding portion 16 is a holding ring arranged at the end of the first measuring rod 1. The holding ring can be easily held by hand and is convenient for the staff to push, pull back or vibrate the first measuring rod 1, further increasing the convenience of the staff's operation.

[0050] In some embodiments, the first measuring rod 1 is composed of a stainless steel square tube, with a holding ring welded at one end and the above-mentioned measuring hook 111 welded at the other end, wherein the material of the measuring hook 111 is the same as that of the first measuring rod 1 .

[0051] This design can increase the structural strength of the first measuring rod 1, thereby increasing the service life of the measuring device.

[0052] In some embodiments, the end of the measuring needle 12 is bent to form a slide groove, and the second measuring rod 2 is slidably matched with the slide groove.

[0053] In this design, the end of the measuring needle 12 is bent to bypass the side of the second measuring rod 2 away from the first measuring rod 1, and then can cooperate with the fixing rod 15 described below to limit the moving direction of the second measuring rod 2, ensuring that the second measuring rod 2 is always parallel to the first measuring rod 2, thereby ensuring the accuracy of the measurement result. Among them, the needle tip of the measuring needle 12 is at the scale plate position, which is convenient for reading.

[0054] In some embodiments, a fixing rod 15 is vertically extended from the first measuring rod 1 , and an adjustment hole is provided at the end of the fixing rod 15 to slide with the second measuring rod 2 .

[0055] In this design, the first measuring rod 1 and the second measuring rod 2 can be spaced apart so that the staff can hold the first measuring rod 1 with one hand and operate the second measuring rod 2 with the other hand, thereby increasing the convenience of the staff's operation.

[0056] In some embodiments, a second adjusting nut 151 is disposed on at least one side of the adjusting hole, and the second measuring rod 2 is a screw rod matching the second adjusting nut 151 .

[0057] Under this design, the second measuring rod 2 and the fixed rod 15 are threadedly matched so that the position of the second measuring rod 2 along its length direction can be changed by rotating the second measuring rod 2, thereby increasing the convenience of adjustment and the accuracy of positioning. At the same time, after the end of the second measuring rod 2 is supported on the outside of the pool wall 3, the second measuring rod 2 can be loosened so that the position of the second measuring rod 2 will not move, which is convenient for the staff to read the numbers.

[0058] In some embodiments, a second gripping portion 22 is provided at one end of the second measuring rod 2 away from the pool wall 3 .

[0059] In this design, the second holding portion 22 can be held by a worker to increase the convenience of rotating the second measuring rod 2 .

[0060] In some embodiments, the second holding portion 22 is a holding nut disposed at the end of the second measuring rod 2 to further increase the convenience of operation for the operator.

[0061] In some embodiments, the second measuring rod 2 is made of stainless steel round steel bars, and the fixing rod 15 is a stainless steel square tube with a second adjusting nut 151 at at least one end to increase the service life of the second measuring rod 2 .
