Description

Technical Field

[0001] The present disclosure relates to the technical field of glass furnaces, and in particular to an expansion measurement device for a glass furnace and a glass furnace. Background Art

[0002] During the production process of the glass kiln, the furnace body of the glass kiln is in a high temperature environment, and it will expand and deform. In order to avoid safety problems caused by damage to the furnace body due to expansion and deformation, the expansion of the furnace body needs to be monitored through an expansion measuring device during the production process.

[0003] For example, the prior art proposes a device for measuring the expansion of the crown of a glass kiln (CN 207113769 U), which includes a horizontal reference line fixed above the crown, and two measuring parts with the same structure and symmetrically arranged on both sides of the crown, each measuring part includes a measuring rod vertically standing on the crown, and the reference line is close to the two measuring rods. In this way, the device for measuring the expansion of the crown of a glass kiln is fixed on the crown, and before the crown expands, the reference line corresponds to the reading on the measuring rod, which is the initial zero point. As the temperature in the furnace gradually increases, the reference line corresponds to the reading on the measuring rod, which will change. That is, the difference between the reading at this time and the initial zero point is the expansion of the crown of the glass kiln. The device for measuring the expansion of the crown of a glass kiln provided by the utility model can accurately measure the expansion of both sides of the crown, and can directly and effectively reflect the height changes on both sides of the crown, reduce misadjustment and ensure the normal operation of the equipment.

[0004] Although the above-mentioned prior art realizes the monitoring of the expansion of the glass furnace body, the workers need to go to the top of the furnace to read the expansion value during the monitoring process. Since the top temperature of the glass furnace is relatively high, this will inevitably bring danger to the personal safety of the workers. Based on this, it is an issue that technicians in this field need to consider whether to monitor the expansion of the glass furnace body and ensure the safety of the workers.

[0026] 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.

[0027] As mentioned in the above background technology, during the production process of the glass kiln, the furnace body of the glass kiln is in a high temperature environment, and it will expand and deform. In order to avoid the safety problems caused by the expansion and deformation damaging the furnace body, it is necessary to monitor the expansion of the furnace body through an expansion measurement device during the production process. Although the monitoring of the expansion of the glass kiln furnace body is achieved through the existing technology, the staff needs to go to the top of the furnace to read the expansion value during the monitoring process. Since the temperature of the top of the glass kiln is relatively high, this will inevitably bring danger to the personal safety of the staff. Based on this, the inventor of the present application provides a glass kiln expansion measurement device and a glass kiln in one or more embodiments. The expansion measurement device measures the distance with the scale at different positions through an infrared rangefinder, and calculates the expansion of the glass kiln through a data processor, which realizes the monitoring of the expansion of the glass kiln while ensuring the safety of the staff. It is believed that it can solve one or more problems in the prior art.

[0028] In view of the above-mentioned technical problems, the present invention provides a device for measuring the expansion of a glass furnace, such as Figure 1 As shown, it includes: a column 1, which is arranged on one side of the glass kiln; a scale 2, which has a trapezoidal cross-section that is larger at the bottom and smaller at the top, and the bottom of the scale 2 is connected to the top wall 3 of the glass kiln; an infrared rangefinder 4, which is arranged on the column 1 to emit horizontal infrared rays 13 to the scale 2, so as to measure the distance between the infrared rangefinder 4 and different parts of the scale 2; a data processor 5, which is connected to the infrared rangefinder 4 to receive the distance value measured by the infrared rangefinder 4, and obtains the expansion amount of the top wall 3 by calculation according to the distance value.

[0029] The measuring principle of the expansion measuring device is as follows Figure 4As shown, before the glass furnace is put into production (the glass furnace has not expanded), the scale 2 is in the first position 11 (initial position), and the infrared rangefinder 4 sends horizontal infrared rays 13 to the scale 2, and the horizontal infrared rays 13 hit the trapezoidal slope of the scale 2, so that the distance L1 from the infrared rangefinder 4 to the scale 2 can be measured, and L1 can be used as a reference distance; after the glass furnace has been put into production for a period of time, due to the high temperature of the glass furnace, the furnace top of the glass furnace expands thermally, causing the scale 2 to move vertically upward and be in the second position 12 (thermal expansion position), at this time, the infrared rangefinder 4 sends horizontal infrared rays 13 to the scale 2, and the horizontal infrared rays 13 hit the trapezoidal slope of the scale 2, so that the distance L2 from the infrared rangefinder 4 to the scale 2 can be measured. Since the height of the infrared rangefinder 4 remains unchanged, the height of the horizontal infrared ray 13 emitted by the infrared rangefinder 4 remains unchanged, while the height of the scale 2 changes during the two measurements, the infrared ray hits the trapezoidal slope of the scale 2 at different positions, so the values ​​L1 and L2 of the two measured intervals are different, that is, L1 is greater than L2. The two measured interval values ​​L1 and L2 are transmitted to the data processor 5, and the data processor 5 calculates the expansion amount of the glass furnace roof based on the interval data.

[0030] When the scale 2 is in different expansion positions, the expansion amount at different expansion positions can be obtained according to the above method. Furthermore, the data processor 5 can be set in a control room far away from the glass kiln, and the staff can obtain the expansion amount of the glass kiln through the data processor 5 in the control room, thereby achieving the expansion amount measurement while ensuring the safety of the staff. Specifically, a controller is set in the control room, and the controller is connected to the infrared rangefinder 4 to control the start and stop of the infrared rangefinder 4. How to achieve distance measurement by infrared ranging is a prior art and will not be repeated here.

[0031] Compared with the prior art, the expansion measuring device of a glass kiln in the present application measures the distance to a scale 2 at different positions by means of an infrared rangefinder 4, and calculates the expansion of the glass kiln by means of a data processor 5, thereby realizing the monitoring of the expansion of the glass kiln and ensuring the safety of the staff.

[0032] In some embodiments, Figure 4 As shown, the expansion amount is: H=LtanA Among them, H is the expansion amount, L=L1-L2, A is the angle between the bottom surface of the scale 2 and the inclined surface of the scale 2, L1 is the distance between the infrared rangefinder 4 and the scale 2 when the glass kiln has not expanded, and L2 is the distance between the infrared rangefinder 4 and the scale 2 after the glass kiln has expanded.

[0033] According to the above calculation formula, corresponding calculation software is developed and loaded on the data processor 5. The data processor 5 can automatically calculate the expansion amount of the glass furnace based on the obtained spacing data, and can display it through the display screen on the data processor 5.

[0034] In some embodiments, Figure 3 As shown, the top wall 3 is provided with embedded bolts 6, and the bottom of the scale 2 is provided with a connecting plate 7, and the connecting plate 7 is connected to the embedded bolts 6. During the construction of the glass furnace, the embedded bolts 6 can be installed on the top wall 3 thereof, and the scale 2 can be integrally formed with the connecting plate 7 during the processing, and a through hole is provided on the connecting plate 7. After the scale 2 and the connecting plate 7 are transported to the site, the through hole on the connecting plate 7 is inserted into the embedded bolts 6, and then the connecting plate 7 is fixed to the embedded bolts 6 by nuts. The connecting plate 7 and the embedded bolts 6 facilitate the on-site installation of the scale 2.

[0035] In some embodiments, Figure 2 As shown, a box 8 is provided on the side wall of the column 1 close to the scale 2, an opening is provided on the side wall of the box 8 close to the scale 2, an infrared rangefinder 4 is provided in the box 8, and an infrared generator of the infrared rangefinder 4 is provided on the opening. The infrared rangefinder 4 is connected to the column 1 through the box 8, and the box 8 also plays a role in maintaining and protecting the infrared rangefinder 4. Specifically, the box 8 can be fixed to the column 1 by bolts.

[0036] In some embodiments, Figure 2 As shown, the expansion measurement device also includes a cooling mechanism, and the cooling water coil 9 of the cooling mechanism is arranged in the box 8 to cool the infrared rangefinder 4. By injecting circulating cooling water into the cooling water coil 9, the infrared rangefinder 4 in the box 8 can be cooled to avoid the problem that the infrared rangefinder is in a high temperature environment and affects its normal operation or is damaged. Furthermore, the box 8 can be coated with fireproof and heat-insulating materials to prevent the heat of the high temperature environment of the glass kiln from being transferred to the box 8 to a certain extent.

[0037] In some embodiments, the cooling mechanism further includes a water tank (not shown in the figure), the water supply port of the water tank is connected to the water inlet of the cooling water coil 9, and the water return port thereof is connected to the water outlet of the cooling water coil 9. The water tank provides a cooling water source for the cooling water coil 9, and forms circulating cooling water in the cooling water coil 9, thereby ensuring cooling and lowering of the infrared rangefinder 4. A cooler (not shown in the figure) is provided in the water tank. The circulating cooling water can be maintained within a certain cooling temperature range by the cooler, thereby ensuring the cooling and lowering effect of the infrared rangefinder 4.

[0038] In some embodiments, the water supply port of the water tank is connected to the water inlet of the cooling water coil 9 through a water pump (not shown in the figure). The water pump can make the cooling water in the cooling water coil 9 have a certain pressure and flow rate, ensuring the cooling effect on the infrared rangefinder 4.

[0039] In some embodiments, a temperature sensor (not shown in the figure) is provided in the box 8 to monitor the temperature in the box 8. The temperature in the box 8 can be monitored in real time through the temperature sensor, and the monitored temperature value is transmitted to the controller in the control room. The controller can instruct the water pump to change the frequency according to the temperature value to adjust the pressure and flow rate of the cooling water in the cooling water coil 9 to achieve a better cooling effect.

[0040] The present invention also provides a glass furnace, comprising the above-mentioned expansion measurement device for the glass furnace.

[0041] In some embodiments, the expansion measuring device includes multiple expansion measuring devices, and the scales 2 of the multiple expansion measuring devices are distributed on the top wall 3 along the process flow direction of the glass furnace. The columns 1 of the multiple expansion measuring devices and the multiple scales 2 are arranged on one side of the glass furnace in a one-to-one correspondence, and an infrared rangefinder 4 is arranged on each column 1. Since different areas are formed in the glass furnace in the process flow direction, the temperature of different areas in the furnace is different according to the glass production process, which leads to different thermal expansion in different areas. By setting up multiple expansion measuring devices, the thermal expansion of different areas can be monitored, so that the distribution of the thermal expansion of the entire furnace body can be obtained, thereby avoiding the problem of shear force damaging the furnace body due to excessive difference in thermal expansion of different areas.

[0042] In summary, compared with the prior art, the present invention provides an expansion measurement device for a glass kiln and a glass kiln and a glass kiln, wherein the expansion measurement device measures the distance to a scale 2 at different positions by an infrared rangefinder 4, and calculates the expansion of the glass kiln by a data processor 5, thereby realizing the monitoring of the expansion of the glass kiln while ensuring the safety of the staff; the safety of the infrared rangefinder 4 is ensured by a box body 8 and a cooling mechanism; and the on-site installation of the scale 2 is facilitated by embedded bolts 6 and connecting plates 7.
