Description

Technical Field

[0001] This application relates to the field of glass production technology, and in particular to an electrode jacking device and method. Background Technology

[0002] In the glass tube melting process, to improve glass melting capacity, an electrode-assisted melting process is typically used. The electrode is inserted into the bottom of the glass furnace to heat the molten glass. However, after the electrode has been inserted for a period of time, the molten glass between the electrode and the insertion hole in the furnace solidifies due to the cooling water jacket surrounding the electrode, preventing further insertion. Therefore, it is necessary to heat the electrode to soften the solidified glass before pushing it into the furnace. In existing technologies, due to varying electrode usage, the pushing force cannot be quantified, easily leading to damage or displacement of the brick structure due to excessive force, resulting in poor reliability.

[0003] Therefore, improving the reliability of the propulsion system has become an urgent problem to be solved. Summary of the Invention

[0004] One of the technical problems this application aims to solve is: how to improve the reliability of propulsion.

[0005] To address the aforementioned technical problems, embodiments of this application provide an electrode jacking device, comprising:

[0006] The propulsion assembly includes a first part, an elastic element, and a second part arranged sequentially along a first direction. The first part moves along the first direction under the action of a first force, and the second part can move relative to the first part along the first direction under the action of the elastic element. The first end of the second part away from the first part is used to connect with an electrode.

[0007] In some embodiments, the propulsion assembly is a hydraulic jack, and the propulsion assembly further includes a hydraulic operating lever. The first part of the hydraulic operating lever is a jack support rod, and the hydraulic operating lever provides a first force to the jack support rod so that the jack support rod moves in a first direction.

[0008] In some embodiments, it also includes:

[0009] A base, on which a propulsion assembly perpendicular to the base is provided, and the first end of the propulsion assembly, which is away from the second part, is connected to the base;

[0010] A distance measuring ruler is set on the base and is used to measure the distance between the base and the bottom of the glass furnace.

[0011] In some embodiments, the propulsion assembly further includes a sleeve, which is sleeved outside the portion of the first portion near the second end, the elastic member, and the portion of the second portion near the second end, wherein the portion of the second portion near the second end moves relative to the sleeve in a first direction under the action of the elastic member.

[0012] In some embodiments, the sleeve is provided with an observation window, which is provided at least in the active area of ​​the elastic element for observing the state of the elastic element.

[0013] In some embodiments, a mark is provided on the second end of the second part, and the observation window also corresponds at least to the range of motion of the mark. The observation window is provided with a scale on the range of motion of the corresponding mark to confirm the movement data of the second part.

[0014] In some embodiments, an adjustment element is provided on the base for adjusting the base so that the propulsion assembly fixed on the base and the electrode connected to the propulsion assembly are both perpendicular to the bottom of the glass furnace.

[0015] In some embodiments, the elastic element is a combination of one or more disc springs.

[0016] On the other hand, this application provides an electrode jacking method, comprising:

[0017] Determine if the elastic force of the elastic element is appropriate;

[0018] If it is not suitable, replace it with a suitable elastic element until it is suitable;

[0019] If appropriate, heat the electrodes until the molten glass between the electrodes and the connection hole at the bottom of the glass furnace softens.

[0020] The first force is applied to the first part so that the elastic element remains in an elastic state, and the electrode advances until the jacking distance is reached.

[0021] In some embodiments, determining whether the elastic force of the elastic element is appropriate includes:

[0022] Measure the distance from the base to the bottom of the glass furnace;

[0023] A first force is applied to the first part to compress the elastic element, and the elastic force acts on the electrode;

[0024] Measure the distance between the base and the bottom of the glass furnace again;

[0025] If the distance decreases, replace the appropriate elastic element until the distance remains constant.

[0026] If the distance remains constant, then the elastic element is suitable.

[0027] Through the above technical solutions, the electrode jacking device and method provided in this application can select different jacking force ranges according to different electrode usage conditions by setting and selecting elastic elements, effectively avoiding displacement or damage to the electrode brick structure, and the electrode jacking force can be applied without intervals, minimizing leakage of the electrode gap glass during the advancement process, ensuring the timeliness of advancement, improving the reliability of electrode advancement, and the operation method is simple and safe.

[0045] Currently, in the glass tube melting process, electrode-assisted melting is commonly used to improve glass melting capacity. An insertion hole is provided at the bottom of the glass furnace, through which the electrode enters the furnace to heat the molten glass. However, after the electrode has been inserted into the furnace for a period of time, the molten glass between the electrode and the inner wall of the insertion hole solidifies due to the cooling water jacket surrounding the electrode. This prevents the electrode from extending further to the required depth. Therefore, the electrode needs to be softened before being pushed into the furnace. However, different electrodes have different requirements, and the thrust cannot be quantified. If the thrust is too small, the electrode cannot be pushed in in time, resulting in increased molten glass gaps and increased resistance, leading to pushing failure. Conversely, if the thrust is too large, it can damage or cause abnormal displacement of the furnace bottom brick structure, resulting in poor reliability. Therefore, this application provides an electrode pushing device that improves thrust reliability and allows for control of the thrust based on the electrode conditions.

[0046] like Figure 1 As shown, the electrode jacking device 1 provided in this application includes:

[0047] The propulsion assembly 11 includes a first part 111, an elastic element 112, and a second part 113 arranged sequentially along a first direction. The first part 111 moves along the first direction under the action of a first force, and the second part 113 can move relative to the first part 111 along the first direction under the action of the elastic element 112. The first end of the second part 113 away from the first part 111 is used to connect with the electrode 2.

[0048] like Figure 1As shown, the electrode advancing device 1 provided in this application includes a pushing assembly 11, which includes a first part 111, a second part 113, and an elastic member 112. The elastic member 112 is disposed between the first part 111 and the second part 113, with its two ends connected to the first part 111 and the second part 113, respectively. The first part 111, the second part 113, and the elastic member 112 all extend along a first direction. The elastic member 112 can elongate or compress in the first direction, thereby allowing the second part 113 to move relative to the first part 111 along the first direction under the action of the elastic member 112. The first end of the second part 113 away from the first part 111 is used to connect to an electrode 2, while the first part 111 can move along the first direction under the action of a first force, thereby pushing the second part 113 and the electrode 2 connected to the second part 113 to move along the first direction, thus pushing the electrode 2 into the glass furnace.

[0049] In this embodiment, when the molten glass 4 between electrode 2 and the inner wall of the connection hole at the bottom of the glass furnace solidifies, making it difficult to push electrode 2 into the glass furnace, the electrode pushing device 1 provided in this application is connected to electrode 2. A first force along the first direction is applied to the first part 111 of the pushing assembly 11, so that the elastic element 112 is pressed. Then, the elastic force is applied to electrode 2 through the second part 113. Under the action of the first force, electrode 2 tends to push into the glass furnace. If electrode 2 pushes into the glass furnace at this time, it is necessary to replace the elastic element 112 with one with less elasticity to avoid damage to the glass furnace during the pushing process. Then, the cooling water of electrode 2 is supplied to the outer casing of electrode 2. A heat insulation structure is provided between electrode 2 and the inlet of the connection hole at the bottom of the glass furnace to keep electrode 2 warm and gradually soften the glass between electrode 2 and the inner wall of the connection hole. After the glass softens, the compressed elastic element 112 will gradually release, so as to provide a thrust to the electrode 2 through the second part 113, and slowly push the electrode 2 into the glass furnace. At the same time, the first force is applied to the first part 111, so that the first part 111 has a thrust along the first direction, so that the elastic element 112 is always in an elastic state until the electrode 2 is pushed in to the pushing distance.

[0050] The electrode jacking device 1 provided in this application jacks the electrode 2. By configuring a suitable elastic element 112 in the pushing assembly 11, the electrode 2 is prevented from being damaged by excessive force during jacking. A first force acts on the first part 111, giving the electrode 2 the force to push it into the glass furnace. This first force keeps the elastic element 112 in an elastic state, thus avoiding the problem of insufficient force causing excessive glass liquid 4 to affect the pushing process. Different jacking force ranges can be selected according to different usage conditions of the electrode 2, effectively preventing displacement or damage to the electrode 2's brick structure. The jacking force of the electrode 2 can be applied without intervals, minimizing leakage of glass from the gaps in the electrode 2 during the pushing process, ensuring timely pushing, improving the reliability of the electrode 2's pushing, and the operation method is simple and safe.

[0051] like Figure 1 As shown in the embodiment of this application, the propulsion component 11 is a hydraulic jack, and the propulsion component 11 also includes a hydraulic operating rod 114. The first part 111 of the hydraulic operating rod 114 is a jack support rod, and the hydraulic operating rod 114 provides a first force to the jack support rod so that the jack support rod moves in a first direction.

[0052] In this embodiment, the propulsion assembly 11 is a hydraulic jack. The first part 111 of the propulsion assembly 11 is a jack support rod, the second part 113 is a push rod, and the elastic element 112 is a disc spring. The hydraulic jack includes a jack support rod, a disc spring, a push rod, and a hydraulic operating rod 114. A disc spring is provided between the jack support rod and the push rod. The two ends of the disc spring are connected to the jack support rod and the push rod, respectively. Moving the hydraulic operating rod 114 up and down can provide a first force to the jack support rod, so that the jack support rod moves in a first direction to drive the compression of the elastic element 112, thereby providing a force for the electrode 2 to be pushed into the glass furnace, thus realizing the insertion of the electrode 2.

[0053] In this embodiment, the specific structure and principle of the hydraulic operating rod 114 in the hydraulic jack providing the first force to the jack support rod through its up-and-down movement are the same as those of related technologies, and will not be repeated here.

[0054] like Figure 1 As shown in the embodiments of this application, it also includes:

[0055] The base 12 has a propulsion assembly 11 perpendicular to the base 12, and the first end of the first part 111 of the propulsion assembly 11, which is away from the second part 113, is connected to the base 12.

[0056] The measuring ruler 13 is set on the base 12 and is used to measure the distance between the base 12 and the bottom 3 of the glass furnace.

[0057] In this embodiment, the electrode jacking device 1 further includes a base 12, a propulsion assembly 11, and a measuring ruler 13. The base 12 is arranged along a second direction, and the first part 111, the second part 113, and the elastic element 112 of the propulsion assembly 11 are arranged along a first direction perpendicular to the second direction. The propulsion assembly 11 is fixedly arranged on the base 12. The first end of the first part 111 of the propulsion assembly 11, which is away from the second part 113, is connected to the base 12, so that the base 12 can provide support for the propulsion assembly 11. The measuring ruler 13 is arranged on the base 12 and is used to measure the distance between the base 12 and the bottom 3 of the glass furnace. When the molten glass 4 between electrode 2 and the inner wall of the connecting hole solidifies, operating the hydraulic operating rod 114 causes the first part 111 to move in the first direction, compressing the elastic element 112 and applying the elastic force to electrode 2 through the second part 113, causing electrode 2 to tend to push into the glass furnace. During this process, the distance between the base and the bottom 3 of the glass furnace can be measured before and after operating the hydraulic operating rod 114 using the measuring ruler 13. If the force provided by the hydraulic operating rod 114 causes a change in the distance measured on both sides of the measuring ruler 13, the elastic force of the elastic element 112 is too large, which may easily damage the bottom 3 of the glass furnace during the pushing process of electrode 2, requiring replacement with an elastic element 112 with less elasticity. If the force provided by the hydraulic operating rod 114 does not cause a change in the distance measured on both sides of the measuring ruler 13, the elasticity of the elastic element 112 is appropriate, allowing for subsequent heat preservation and pushing of electrode 2. The measuring ruler 13 facilitates the measurement of the distance between the base 12 and the bottom 3 of the glass furnace.

[0058] like Figure 1 As shown in the embodiment of this application, the propulsion assembly 11 further includes a sleeve 115, which is sleeved on the portion of the first part 111 near its second end, the elastic member 112, and the portion of the second part 113 near its second end. The portion of the second part 113 near its second end moves relative to the sleeve 115 in a first direction under the action of the elastic member 112. The second end of the first part 111 is the other end opposite to the first end, and the second end of the second part 113 is the other end opposite to the first end.

[0059] In this embodiment, the propulsion assembly 11 includes a first portion 111, a second portion 113, an elastic element 112, and a sleeve 115, all extending along a first direction. The first end of the first portion 111 is fixedly connected to the base 12, the second end of the first portion 111 is connected to the first end of the elastic element 112, and the second end of the second portion 113 is connected to the second end of the elastic element 112. The second end of the second portion 113 is used to connect to the electrode 2. During installation, the second end of the first portion 111 is connected to the first end of the elastic element 112. Then, the sleeve 115 is fitted over the portion of the first portion 111 near its second end, and the second end of the second portion 113 is inserted into the sleeve 115, thus fitting over the portions of the first portion 111 near its second end, the elastic element 112, and the second portion 113 near their second ends. The arrangement of the sleeve 115 improves the stability of the connection between the first part 111 and the second part 113 via the elastic member 112, and can better limit the first part 111, the elastic member 112 and the second part 113, so that the first part 111, the elastic member 112 and the second part 113 can move along the first direction, thereby restricting the movement direction of the second part 113, so that the second part 113 moves relative to the sleeve 115 along the first direction under the action of the elastic member 112.

[0060] like Figure 2 As shown in this embodiment, the sleeve 115 is provided with an observation window 1151, which is provided at least in the active area of ​​the elastic member 112 for observing the state of the elastic member 112.

[0061] In this embodiment, the sleeve rod 115 is provided with an observation window 1151, which corresponds at least to the active area of ​​the elastic member 112, so that the compression or release state of the elastic member 112 can be observed, so as to adjust the force of the hydraulic operating rod 114 on the jack support rod in a timely manner. This allows for determining whether the elastic force of the elastic member 112 is appropriate, checking whether the elastic member 112 is in a compressed state, and confirming that the elastic member 112 is always in an elastic state when the electrode 2 is being pushed forward, by observing through the observation window 1151.

[0062] like Figure 2 As shown in the embodiment of this application, a mark 1131 is provided on the second end of the second part 113, and the observation window 1151 is at least corresponding to the range of motion of the mark 1131. The observation window 1151 is provided with a ruler 1152 on the range of motion of the corresponding mark 1131 to confirm the movement data of the second part 113.

[0063] In this embodiment, a mark 1131 is provided on the second end of the second part 113, and an observation window 1151 is also provided in the corresponding range of motion of the mark 1131. The observation window 1151 is provided with a scale 1152 in the corresponding range of motion of the mark 1131. So when the second part 113 moves, the movement data of the second part 113 can be determined according to the scale on the scale 1152 corresponding to the mark 1131, thereby determining the insertion data of the electrode 2.

[0064] like Figure 1 As shown in the embodiment of this application, an adjustment member 14 is provided on the base 12 for adjusting the base 12 so that the propulsion assembly 11 fixed on the base 12 and the electrode 2 connected to the propulsion assembly 11 are both perpendicular to the bottom 3 of the glass furnace.

[0065] In this embodiment, the base 12 is provided with adjusting members 14 on both sides of the propulsion assembly 11. The adjusting members 14 are adjusting screws. By tightening or loosening the two adjusting screws, the angle of the base 12 is adjusted, thereby adjusting the direction of the propulsion assembly 11 set on the base 12. This ensures that the propulsion assembly 11 and the electrode 2 are both set in a direction perpendicular to the bottom 3 of the glass furnace, which ensures that the electrode 2 can be better pushed into the glass furnace. It also avoids the electrode 2 exerting force on the inner wall of the connecting hole during the movement, thus preventing damage to the glass furnace.

[0066] like Figure 3 As shown in the embodiments of this application, the elastic element 112 is a combination of one or more disc springs.

[0067] In this embodiment, the elastic element 112 can be a single disc spring or a combination of multiple disc springs stacked along the first direction. The multiple disc springs can have different elasticities, thereby forming an elastic force adapted to the corresponding electrode 2, so that when the electrode 2 is pushed forward, it will not damage the glass furnace, but can be pushed forward in time.

[0068] like Figure 3 As shown, in this embodiment, the elastic element 112 may include three disc springs, which include a first disc spring 1121, a second disc spring 1122 and a third disc spring 1123 arranged sequentially along the first direction, or two disc springs, or other numbers of disc springs, as long as they are suitable for production and application. At least one of the disc springs has a different elasticity.

[0069] In this embodiment, the second part 113 is connected to the electrode 2 by an insulating connector 15. The insulating connector 15 can be a ceramic block or an alumina material, which has high pressure resistance and good insulation.

[0070] This application provides an electrode jacking device 1, in which a base 12 is positioned directly below the electrode 2 to be advanced. The base 12 is secured by adjusting the adjusting screws. A hydraulic jack is vertically mounted on the base 12. The first end of the hydraulic jack's jack rod is used to connect with the electrode 2, allowing the electrode 2 to extend into the connection hole at the bottom 3 of the glass furnace. The extension direction of the electrode 2 is the same as the extension direction of the connection hole, both being perpendicular to the bottom 3 of the glass furnace. After installing the electrode jacking device 1, open the laser rangefinder 13 to continuously monitor the distance from the base 12 to the bottom 3 of the glass furnace. Loosen the electrode fastening screw 16 to allow the electrode 2 to move. Operate the hydraulic operating lever 114 to slowly raise the first part 111. Observe through the observation window 1151 that the elastic element 112 is being pressed. First, the low-elasticity disc spring is pressed, and the elastic stress is applied to the electrode 2. Observe whether the measurement data of the laser rangefinder 13 changes. If there is a change, select the elastic element 112 with lower elasticity. If there is no change in the measurement data of the laser rangefinder 13, then there is no change in the elastic element 112. Then, perform a heat preservation operation on the electrode 2, cut off the cooling water supply to the electrode water jacket inlet pipe 51 on the electrode 2, and remove the electrode water jacket. Water pipe 52 rubber hose, add heat insulation cotton 6 in the gap between electrode 2 and the inlet of the connection hole and at the electrode water jacket 5, thereby raising the temperature of the glass seeping into the gap between electrode 2 and the connection hole until the glass gradually softens. Observe the mark 1131 of the second part 113, record the position of mark 1131 on the scale 1152, and grasp the change of the jacking displacement of the second part 113. After the change begins, observe the elastic release state of the elastic element 112 through the observation window 1151 at all times. According to the elastic release state of the elastic element 112, continuously operate the hydraulic operating rod 114 to keep the selected elastic element 112 of appropriate specification always in the state of elastic force. During this process, electrode 2 is continuously jacked into the glass furnace until electrode 2 moves to the jacking distance. At this point, reduce the jacking force of the hydraulic jack to restore the elastic element 112 to its initial state, tighten the electrode fastening screw 16 to fix the electrode 2, remove and move the electrode jacking device 1, remove the insulation cotton 6, and slowly restore the water supply to the electrode water jacket 5. First, slightly open the water inlet pipe 51 of the electrode water jacket to supply water, and steam will continuously emerge from the outlet of the return water pipe 52 of the electrode water jacket. Slowly open the water jacket cooling water inlet, and the steam will gradually decrease until it becomes a water flow. At this point, connect the return water pipe to restore the normal cooling water volume, and the jacking of the electrode 2 is completed.

[0071] Therefore, the electrode 2 jacking method provided in this application, through the setting and selection of the elastic element 112, allows for the selection of different jacking force ranges according to different usage conditions of the electrode 2, effectively preventing displacement or damage to the brick structure of the electrode 2. The jacking force of the electrode 2 can be applied without intervals, minimizing leakage of the glass gaps in the electrode 2 during the advancement process, ensuring timely advancement, and enabling live-line work. The operation method is simple, reliable, and safe.

[0072] like Figure 4As shown, on the other hand, this application also provides an electrode jacking method, comprising:

[0073] S101, Determine whether the elastic force of the elastic element is appropriate;

[0074] The propulsion assembly contains an elastic element. The magnitude of the elastic force of the elastic element determines the magnitude of the force that pushes the electrode into the glass furnace. When the elastic force is appropriate, the elastic element can push the electrode into the glass furnace in time without damaging the bottom of the glass furnace.

[0075] S102, if not suitable, replace with a suitable elastic element until suitable;

[0076] If the elastic force of the elastic element is too small, the electrode will not be able to be pushed into the glass furnace in time, resulting in too much molten glass in the gap between the electrode and the bottom connection hole of the glass furnace, which will increase the resistance and cause the pushing failure. If the elastic force of the elastic element is too large, the electrode will be pushed into the glass furnace with too much force, which may easily damage the glass furnace.

[0077] S103, if appropriate, perform heat preservation operation on the electrode until the molten glass between the electrode and the connection hole at the bottom of the glass furnace softens;

[0078] After finding a suitable elastic element, the electrode can be insulated. The cooling water supply to the electrode water jacket inlet pipe is cut off, and the electrode water jacket return pipe hose is removed. Insulation cotton is added to the gap between the electrode and the inlet of the connection hole and the electrode water jacket, thereby raising the temperature of the glass seeping into the gap between the electrode and the connection hole until the glass gradually softens.

[0079] S104, the first force is applied to the first part so that the elastic element remains in an elastic state, and the electrode advances until the jacking distance is reached.

[0080] As the molten glass gradually softens, the elastic element gradually changes from compression to release, and provides a thrust to the electrode through the second part, enabling the electrode to be pushed into the glass furnace. During the release of the elastic element, the release state of the elastic element is constantly observed through the observation window, and the hydraulic operating lever is operated according to the release state of the elastic element to provide the first force to the first part. The first force is the force that keeps the elastic element in an elastic state until the electrode is pushed into the glass furnace to the pushing distance under the action of the elastic element, at which point the pushing of the electrode is completed.

[0081] This application provides an electrode jacking method, in which a base is set directly below the electrode to be jacked up, and a jacking component is vertically set on the base. The first end of the second part of the jacking component is used to connect with the electrode, so that the electrode extends into the connection hole at the bottom of the glass furnace. The extension direction of the electrode is the same as the extension direction of the connection hole, both being perpendicular to the bottom of the glass furnace. After the electrode jacking device is installed, determine whether the elastic force of the elastic element in the electrode jacking device is appropriate. If not, replace it with a suitable elastic element until it is appropriate. If it is appropriate, perform a heat preservation operation on the electrode, cut off the cooling water supply to the electrode water jacket inlet pipe, and remove the electrode water jacket return pipe hose. Add heat insulation cotton in the gap between the electrode and the inlet of the connection hole and at the electrode water jacket to raise the temperature of the glass seeping into the gap between the electrode and the connection hole until the glass gradually softens. Observe the second part of the mark and record the position of the mark on the scale to grasp the change of the second part of the jacking displacement. After the change begins, observe the elastic release state of the elastic element through the observation window at all times. According to the elastic release state of the elastic element, continuously operate the hydraulic operating lever to keep the selected elastic element of appropriate specification in the state of elastic force. During this process, the electrode is continuously jacked into the glass furnace until the electrode moves to the jacking distance. At this point, reduce the jacking force of the hydraulic jack to restore the elastic element to its initial state, tighten the electrode fixing screw to fix the electrode, remove and move the electrode jacking device, remove the insulation cotton, and slowly restore the water supply to the electrode water jacket. First, slightly open the water inlet pipe of the electrode water jacket to supply water, and steam will continuously emerge from the outlet of the return pipe of the electrode water jacket. Slowly increase the opening of the water jacket cooling water inlet, and the steam will gradually decrease until it becomes a water flow. At this point, connect the return pipe to restore the normal cooling water volume, and the electrode jacking is completed.

[0082] Therefore, the electrode jacking method provided in this application keeps the elastic element suitable for the corresponding electrode in an elastic state under the action of a first force. This allows for the selection of different jacking force ranges according to different electrode usage conditions, effectively avoiding displacement or damage to the electrode brick structure. The electrode jacking force can be applied without intervals, minimizing leakage of the electrode gap glass during the advancement process, ensuring timely advancement, and enabling live-line work. The operation method is simple, reliable, and safe.

[0083] like Figure 5 As shown, this application also provides another electrode jacking method, including:

[0084] S201, Measure the distance from the base to the bottom of the glass furnace;

[0085] A laser rangefinder is installed on the base to measure the distance between the base and the bottom of the glass furnace.

[0086] S202, a first force is applied to the first part to compress the elastic element, and the elastic force acts on the electrode;

[0087] By applying a first force to the first part through hydraulic operation, the elastic element is compressed, and the elastic element can exert a spring force on the electrode through the second part, causing the electrode to tend to push into the glass furnace.

[0088] S203, Measure the distance from the base to the bottom of the glass furnace again;

[0089] S204, compare whether the distance from the base to the bottom of the glass furnace measured on both sides remains unchanged;

[0090] S205, if the distance decreases, replace the appropriate elastic element until the distance remains constant;

[0091] If the distance between the base and the bottom of the glass furnace is measured later and is smaller than the first measurement, the electrode has been pushed into the glass furnace a certain distance. If the elastic element is too large, it may easily damage the glass furnace during subsequent electrode pushing operations.

[0092] S206, if the distance remains unchanged, the elastic element is suitable, and the electrode is kept warm until the molten glass between the electrode and the connection hole at the bottom of the glass furnace softens.

[0093] If the distance between the two measurements remains unchanged, then the elastic force of the elastic element is appropriate, and the electrode should be kept warm.

[0094] S206, the first force is applied to the first part so that the elastic element remains in an elastic state, and the electrode advances until the jacking distance is reached.

[0095] Another electrode advancing method provided in this application involves a base positioned directly below the electrode to be advanced. An advancing assembly is vertically mounted on the base. The first end of the second part of the advancing assembly connects to the electrode, allowing it to extend into the connection hole at the bottom of the glass furnace. The electrode's extension direction is the same as the extension direction of the connection hole, both perpendicular to the bottom of the glass furnace. After installing the electrode advancing device, the laser rangefinder is used to continuously monitor the distance from the base to the bottom of the glass furnace. The electrode fastening screw is loosened to allow the electrode to move. The hydraulic operating lever is operated to slowly raise the first part. Observation is made through the observation window to see if the elastic element is compressed. First, the low-elasticity disc spring is compressed, and the elastic stress acts on the electrode. Observation is made to see if the laser rangefinder measurement data changes. If it changes, an elastic element with lower elasticity is selected. If the laser rangefinder measurement data does not change, the elastic element remains unchanged. The electrode is then kept warm, the cooling water supply to the electrode water jacket inlet pipe is cut off, and the electrode water jacket is removed. Add insulation cotton to the gap between the electrode and the inlet of the connection hole and at the electrode water jacket, thereby raising the temperature of the glass seeping into the gap between the electrode and the connection hole until the glass gradually softens. Observe the second part of the mark and record the position of the mark on the scale to grasp the change of the second part of the jacking displacement. After the change begins, observe the elastic release state of the elastic element through the observation window at all times. According to the elastic release state of the elastic element, continuously operate the hydraulic operating rod to keep the selected elastic element of appropriate specification in the state of elastic force. During this process, the electrode is continuously jacked into the glass furnace until the electrode moves to the jacking distance. At this point, reduce the jacking force of the hydraulic jack to restore the elastic element to its initial state, tighten the electrode fixing screw to fix the electrode, remove and move the electrode jacking device, remove the insulation cotton, and slowly restore the water supply to the electrode water jacket. First, slightly open the water inlet pipe of the electrode water jacket to supply water, and steam will continuously emerge from the outlet of the return pipe of the electrode water jacket. Slowly increase the opening of the water jacket cooling water inlet, and the steam will gradually decrease until it becomes a water flow. At this point, connect the return pipe to restore the normal cooling water volume, and the electrode jacking is completed.

[0096] Therefore, the electrode jacking method provided in this application, through the setting and selection of elastic elements, allows for the selection of different jacking force ranges according to different electrode usage conditions, effectively avoiding displacement or damage to the electrode brick structure. The electrode jacking force can be applied without intervals, minimizing leakage of the electrode gap glass during the advancement process, ensuring timely advancement, and enabling live-line work. The operation method is simple, reliable, and safe.

[0097] In this embodiment, the propulsion assembly is a hydraulic jack. The first part of the propulsion assembly is a jack support rod, the second part is a push rod, and the elastic element is a disc spring. The hydraulic jack includes a jack support rod, a disc spring, a push rod, and a hydraulic operating rod. A disc spring is provided between the jack support rod and the push rod. The two ends of the disc spring are connected to the jack support rod and the push rod, respectively. The disc spring can be a combination of multiple disc springs. Moving the hydraulic operating rod up and down can provide a first force to the jack support rod, causing the jack support rod to move in a first direction to drive the compression of the elastic element, thereby providing a force to push the electrode into the glass furnace, thus realizing the insertion of the electrode.
