Description

Technical Field

[0001] This invention belongs to the field of float glass production technology, and specifically relates to a novel method for binding bricks to the walls of an ultra-thin float glass melting furnace. Background Technology

[0002] The wall bricks of float glass melting furnaces, constantly exposed to high-temperature molten glass, gradually thin due to chemical erosion and fluid flow. Once the erosion reaches a warning level, there is a risk of molten glass leakage. Wall-binding is a hot-repair process that involves replacing old furnace walls with new refractory bricks. This extends the furnace's service life and avoids production losses caused by major shutdowns. The production of ultra-thin float glass demands higher requirements for furnace temperature stability, glass quality, and production continuity, placing even stricter demands on the efficiency, precision, and safety of the wall-binding operation.

[0003] Currently, brick-binding of pool walls is mostly done manually: cooling ducts and railings in the work area are manually removed, the old pool wall surface is ground and cleaned, new bricks are manually moved and attached, angle steel is welded for temporary fixation, and finally the iron grates, railings, and cooling ducts are reinstalled. This method has significant drawbacks: the work area has high temperatures, posing significant safety risks for close-range manual operation; brick handling is labor-intensive; after removing the fixed cooling ducts, the pool wall loses forced cooling, causing a rapid temperature rise, which can exacerbate brick erosion and even lead to leakage risks; the accuracy of manual brick-binding is greatly affected by the skill of the personnel, temporary fixation relies on on-site welding, the process is cumbersome and inefficient, and the consistency of brick-binding quality is poor.

[0004] In existing improvement schemes, some processes involve solidifying localized molten glass through cooling water pipes and hooks before further processing. While this reduces the risk of leakage, it disrupts the thermal balance within the kiln and can easily lead to defects such as bubbles and stone formation in the glass, making it unsuitable for ultra-thin float glass production. Another scheme uses a detachable top screw structure to replace welding reinforcement, achieving weld-free operation. However, this only optimizes the reinforcement process; core processes such as brick handling and bonding still rely on manual labor. It also fails to address the issue of pool wall temperature control during cooling switching, making it impossible to achieve fully mechanized operation and safety management throughout the entire process. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the hot brick binding of the pool wall of the existing ultra-thin float glass melting furnace relies on manual operation, which has the problems of high safety risk of high temperature operation, high labor intensity, low construction efficiency, and loss of control of pool wall temperature and poor consistency of brick binding quality during the cooling switching process.

[0006] The technical solution of the present invention is as follows: A novel method for binding bricks to the wall of an ultra-thin float glass melting furnace is implemented under the hot condition of normal furnace production and before the molten glass inside has solidified entirely. It employs a high-temperature resistant integrated furnace wall equipment that integrates a universal robotic arm, a movable temporary cooling air system, and a temporary top iron fixing device. This equipment, along with a detachable temporary track laid along the length of the furnace wall, completes the brick-binding operation. The method includes the following steps: S1. Lay a detachable temporary track along the length of the pool wall on the outside of the pool wall to be bound, install the pool wall integrated equipment on the temporary track, and lock the pool wall integrated equipment in position after moving it to the first area to be bound. S2. Activate the movable temporary cooling air device of the pool wall integrated equipment to make the cooling airflow fully cover the outer surface of the pool wall in the first area to be bricked, and collect the pool wall temperature at multiple points in the area in real time. S3. After the regional temperature characteristic value and temperature rise rate meet the hot working conditions, reduce or stop the air supply to the fixed cooling duct corresponding to the first brick-binding area, and remove at least part of the fixed cooling duct to form a brick-binding working space; during the removal process, maintain the continuous operation of temporary cooling and dynamically adjust the temporary cooling parameters according to the real-time temperature. S4. Remove the fixed iron bars and iron grates in the first area to be bricked, clean and polish the outer surface of the old pool wall to remove glass deposits, eroded loose layers, refractory material debris and surface protrusions, and form a flat base surface for bricking. S5. The new tile is picked up by the universal robotic arm device according to the preset clamping parameters. After path planning, the new tile is transported to the tile base surface. The spatial position and posture of the new tile are adjusted so that the new tile is attached to the outer surface of the old pool wall. S6. While maintaining the position and posture of the new tile, apply multiple temporary clamping forces to the new tile using the temporary top iron fixing device. Once the clamping force reaches the set range and the bonding gap meets the requirements, release the clamping of the universal robotic arm device. S7. While maintaining the temporary tightening state, reinstall the iron grate and fixed iron bar, so that the fixed iron bar can permanently fix the newly laid bricks through the iron grate; S8. Reinstall the fixed cooling air duct and restore the air supply. After the cooling state of the fixed cooling air duct meets the operating conditions of the kiln, release the tightening action of the temporary top iron fixing device and stop the temporary cooling air device. S9. Release the locking position of the pool wall integrated equipment, move it along the temporary track to the next area to be bricked, and repeat steps S2 to S8 until all brick-binding operations of the predetermined pool wall section are completed.

[0007] Preferably, step S1 specifically includes: 1.1. Multiple modular track units are sequentially spliced ​​along the length of the pool wall to form a temporary track; 1.2 Adjust the support height and lateral position of each track unit point by point so that the difference in track surface height and lateral misalignment between adjacent track units are within the preset allowable range; 1.3 Lock the adjacent track units and install a high-temperature resistant insulation layer between the temporary track and the supporting foundation next to the kiln; 1.4 After the pool wall integrated equipment reaches the area to be bound with bricks, it shall perform mechanical locking and position detection. If the position locking is not completed, it is prohibited to carry out new brick delivery and temporary tightening operations.

[0008] Preferably, steps S2 and S3 strictly follow the implementation sequence of first establishing temporary cooling and then weakening fixed cooling, specifically including: Multiple temperature detection points were set up along the length and height of the pool wall in the area to be bricked. Activate the portable temporary cooling air device to allow the cooling airflow to cover all pool wall areas that will be exposed after the fixed cooling air ducts are removed; Calculate the regional temperature characteristic value and regional temperature rise rate based on the multi-point temperature detection results; Air supply to the corresponding fixed cooling duct may be reduced or stopped only when the regional temperature characteristic value is not higher than the first temperature threshold and the regional temperature rise rate is not higher than the set temperature rise rate. During the dismantling of the fixed cooling duct and subsequent brick-binding work, the air volume, air direction and air position of the temporary cooling are dynamically adjusted according to real-time temperature data.

[0009] Preferably, the regional temperature characteristic value is calculated and determined according to the following formula: ; In the formula, For regional temperature characteristic values, The highest temperature at multiple temperature monitoring points. For multi-point average temperature, The highest temperature is the weighting coefficient, and ; When the regional temperature characteristic value is not higher than the first temperature threshold, the current temporary cooling air supply status is maintained. When the regional temperature characteristic value is higher than the first temperature threshold but not higher than the second temperature threshold, the temporary cooling air volume is gradually increased. When the area temperature characteristic value is higher than the second temperature threshold, the current brick-binding operation should be immediately suspended, and temporary cooling should be maintained until the area temperature characteristic value drops back to the allowable operating range.

[0010] Preferably, the target air volumetric flow rate for temporary cooling is determined by the following formula: ; In the formula, For the target air volume flow rate, For cooling safety factor, The convective heat transfer coefficient of the pool wall surface. The effective heat exchange area of ​​the pool wall to be cooled. The absolute temperature of the pool wall surface. This refers to the absolute temperature of the cooling airflow inlet. The emissivity of the pool wall surface, The Stefan-Boltzmann constant is... The absolute temperature of the environment surrounding the pool wall. To cool the gas density, For the isobaric specific heat capacity of the cooling gas, Allowed temperature rise for cooling gas; Adjust the fan speed or air duct opening of the temporary cooling air device according to the target air volume flow rate, so that the deviation between the actual air volume flow rate and the target value is within the preset allowable range.

[0011] Preferably, step S4 specifically includes: 4.1 Collect distance data of multiple detection points on the outer surface of the old pool wall relative to the predetermined tiling reference surface; 4.2 Identify raised areas, loose erosion areas, areas with attached glass deposits, and recessed areas on the surface of the old pool wall based on distance data; 4.3 Clean and polish in sequence from top to bottom and from areas with large protrusions to areas with small protrusions; 4.4 After cleaning and polishing, re-collect the distance data of each detection point, continue to polish and correct areas with excessive protrusion, and mark areas with excessive indentation as differentiated tightening areas.

[0012] Preferably, in step S5, the path with the lowest overall cost value is selected from multiple candidate conveying paths as the new tiling conveying path, and the overall cost value is calculated using the following formula: ; In the formula, To comprehensively represent value, The candidate path length, This serves as the baseline value for path length. For the first The ambient temperature at each sampling point along the path. To allow for operating temperature, For temperature normalization parameters, For the first The robotic arm load rate corresponding to each sampling point To allow for load rate, This is a load factor normalization parameter. The curvature at the corresponding position of the path. As the curvature reference value, The minimum distance between new tiling or conveying mechanisms and obstacles. This is the baseline value for safe distance. The number of path sampling points. Weighting coefficients that are greater than zero; All candidate conveying paths simultaneously meet the requirements of the robotic arm's range of motion, rated load, minimum safe distance, and new tile-laying posture adjustment.

[0013] Preferably, step S5 further includes: 5.1 Determine the target clamping force based on the quality, size, and surface condition of the newly laid tiles; 5.2 Apply clamping force from both sides of the newly laid tiles and install a fall-prevention support structure at the bottom of the newly laid tiles; 5.3 During the conveying process, the actual clamping force and the displacement of the new tile relative to the clamping position are detected in real time; 5.4 When the actual clamping force is lower than the anti-fall threshold, the clamping force change rate exceeds the standard, or abnormal displacement occurs in the newly laid tiles, immediately stop the conveying and maintain the clamping state; 5.5 When the new tile enters the set distance range from the tile base, reduce the conveying speed to low speed and adjust the horizontal position, vertical position and tilt angle of the new tile in sequence.

[0014] Preferably, in step S6, multiple independent tightening forces are applied at different positions of the newly laid tiles, and the target tightening force at each tightening position is distributed according to the amount of indentation in the old pool wall and the gap between the new tiles and the wall. The distribution formula is as follows: ; Wherein the weighting coefficients are: ; In the formula, For the first The target clamping force at the top position. The total clamping force for newly laid tiles, The number of positions to be tightened. For the first Load allocation weights for each top-tight position This represents the amount of indentation in the old pool wall at the corresponding location. This is the baseline value for the amount of dent. To create gaps for the new tiles in the corresponding locations. To match the reference value of the gap, and It is a non-negative correction factor; Adjust the clamping displacement according to the deviation between the actual clamping force and the target value at each clamping position, so that the bonding gap at each detection position of the newly laid tile is within the preset allowable range.

[0015] Preferably, the entire brick-binding process employs multi-level safety interlocking control, and the interlocking rules include: When the integrated pool wall equipment has not been locked in place, it is prohibited to transport new tiles or perform temporary tightening. When temporary cooling fails to reach the set air supply status, the area temperature characteristic value exceeds the allowable operating temperature, or the temperature rise rate exceeds the standard, it is prohibited to remove the fixed cooling duct or proceed with the new tile installation process. Lifting or conveying new tiles is prohibited before they reach the set clamping state. If the temporary clamping force does not reach the set range or the bonding gap does not meet the standard, the clamping of the newly laid tiles must not be released. When the iron grate and fixed iron railing are not fully installed and fixed, it is forbidden to loosen the temporary tightening. Temporary cooling must not be stopped until the fixed cooling duct has been restored to the set air supply state; If any abnormalities are detected, such as abnormal position locking, abnormal clamping, abnormal clamping, abnormal pool wall temperature, or abnormal communication, the conveying of new bricks shall be stopped immediately, and the clamping, temporary clamping, and position locking states shall be maintained, and an alarm signal shall be output.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Reduce operational safety risks and manual labor intensity by using integrated mechanical equipment to complete brick conveying, bonding and temporary fixing, thereby reducing the time and physical burden of personnel working at close range in high-temperature environments; 2. To ensure the structural safety of the kiln during hot operation, a switching logic of first establishing temporary cooling and then dismantling fixed cooling is adopted, combined with closed-loop temperature control, to avoid the pool wall from experiencing a sudden temperature rise and accelerated erosion due to loss of cooling. 3. Improve the overall efficiency of brick-binding operations. The equipment moves along the detachable track to operate in sections, with tight process connections. There is no need to repeatedly disassemble and assemble temporary tools, which effectively shortens the operation cycle of a single section. 4. Improve the consistency of brick binding quality. Through precise posture adjustment of the robotic arm, multi-point differentiated tightening and full-process interlocking control, ensure uniform gap between bricks and reasonable fixing force, and avoid the impact of skill differences in manual operation on construction quality.

[0018] Example 1: This embodiment focuses on the standard hot brick-binding operation of a single section of the pool wall in an ultra-thin float glass melting furnace. The operation section corresponds to the pool wall area on the side of a single small furnace, and is implemented according to the following steps: S1, Combination Figure 1 , Figure 2 As shown, a detachable temporary track 1 is laid along the length of the pool wall on the outside of the pool wall to be bound; multiple modular track units are spliced ​​together in sequence, and the support height and lateral position of each track unit are adjusted point by point to control the height difference of the track surface of adjacent track units to be no more than 2 mm and the lateral misalignment to be no more than 1.5 mm. The connection structure of adjacent track units is locked, and a high-temperature heat-resistant insulation layer is laid between the temporary track and the support foundation next to the kiln; the pool wall integrated equipment 2 is hoisted onto the detachable temporary track 1, the drive equipment is moved to the first area to be bound, and mechanical locking is performed. The position locking status is checked, and the next process is entered after confirming that the locking is reliable. S2, Combination Figure 1 , Figure 3 As shown, 6 to 8 temperature detection units 8 are arranged along the length and height of the pool wall in the area to be bricked, covering the entire height range of the old pool wall bricks 3; the movable temporary cooling air device 22 is activated to make the cooling airflow fully cover the outer surface of the pool wall in the area to be bricked, and the coverage range extends at least 100mm beyond the boundary of the area exposed after the removal of the fixed cooling air duct 5; the pool wall temperature at multiple points is collected in real time through the temperature detection units 8, and the regional temperature characteristic value and regional temperature rise rate are calculated. S3, the regional temperature characteristic value is calculated according to the formula. The calculation is performed, with the highest temperature weighting coefficient η set to 0.7. When the regional temperature characteristic value is not higher than the first temperature threshold of 280 ℃ and the regional temperature rise rate is not higher than 5 ℃ / min, the hot working conditions are deemed met. After the working conditions are met, the air supply of the fixed cooling duct 5 in the corresponding section is gradually reduced, the fixed cooling duct 5 in the working section is dismantled, and space is made for brick binding. During the dismantling process, the regional temperature characteristic value is continuously monitored. When the temperature rises, the air supply of the temporary cooling is increased simultaneously to maintain the stability of the pool wall temperature. If the regional temperature characteristic value is higher than the second temperature threshold of 350 ℃, the dismantling operation is immediately suspended, the temporary cooling continues to operate, and the operation is resumed after the temperature drops back to the allowable range. S4, Combination Figure 1 , Figure 4As shown, the fixed iron bar 6 and iron grate 7 in the first area to be bricked are removed. The outer surface of the old pool wall bricks 3 is cleaned and polished using a grinding device to remove the attached glass deposits, eroded loose layers, refractory material debris and surface protrusions. Before grinding, the distances of multiple detection points on the outer surface of the old pool wall relative to the predetermined brick-laying reference surface are collected to identify the protruding and recessed areas. Grinding is carried out in order from top to bottom and from large protrusions to small protrusions. After grinding, the distances of each detection point are remeasured to control the protrusion within 0.5mm. At the same time, the areas with excessive recesses are recorded and marked as differentiated tightening areas. S5. Set the target clamping force according to the quality, size and surface condition of the new tile 4. Apply clamping force from the opposite sides of the new tile 4 through the universal robotic arm device 21, and set an anti-fall support structure at the bottom of the new tile 4. Use a multi-constraint path planning algorithm to generate a conveying path. Take into account the path length, path ambient temperature, robotic arm load rate, path curvature and obstacle safety distance, and select the path with the lowest comprehensive cost as the conveying path. Detect the actual clamping force and the displacement state of the new tile 4 in real time during the conveying process. When the clamping force is lower than the anti-fall threshold or abnormal displacement occurs, stop the conveying immediately and maintain the clamping state. When the new tile 4 enters the range of 200mm from the tile base surface, reduce the conveying speed to low speed and adjust the horizontal position, vertical position and tilt angle of the new tile 4 in sequence so that the new tile 4 is flat and adhered to the outer surface of the old pool wall tile 3. S6. Maintain the position and posture of the newly laid tile 4, activate the temporary top iron fixing device 23, and apply independent tightening forces to the upper, middle, and lower positions of the newly laid tile 4; calculate the target tightening force for each tightening position according to the marked differential tightening area and the tightening force distribution formula, and increase the tightening force distribution weight for positions with larger indentations; detect the actual tightening force and bonding gap at each position in real time, and control the bonding gap of each tightening point within 0.3mm by fine-tuning the displacement of each tightening point; after confirming that the tightening force and bonding gap meet the requirements, release the clamping of the universal robotic arm device 21 and retract the robotic arm; S7. While maintaining the temporary tightening state, reinstall the iron grate 7 and the fixed iron block 6 to tighten the connection structure, so that the fixed iron block 6 can permanently fix the newly laid bricks 4 through the iron grate 7. S8. Reinstall the fixed cooling air duct 5 and gradually restore the air supply. After the air supply status of the fixed cooling air duct 5 reaches the normal operation requirements of the kiln and the pool wall temperature stabilizes, release the tightening effect of the temporary top iron fixing device 23 and stop the operation of the movable temporary cooling air device 22. S9. Release the mechanical lock of the pool wall integrated equipment 2, move the equipment along the detachable temporary track 1 to the next brick-binding area, and repeat steps 2 to 8 until all brick-binding operations in the predetermined section are completed; after all operations are completed, remove the pool wall integrated equipment 2 and the detachable temporary track 1, and collect and organize the tooling.

[0019] Example 2: This embodiment addresses the hot brick-binding operation on a long section of the pool wall in an ultra-thin float glass melting furnace where localized erosion and depressions are severe. The operation section covers the pool wall length corresponding to 2-3 small furnaces, and the maximum localized depression in the pool wall exceeds 3mm. The operation is carried out according to the following steps: S1, Combination Figure 2 As shown, modular and detachable temporary tracks 1 are continuously laid along the long section to be worked on, with the total length of the tracks covering the entire area to be bound with bricks, and the height difference between adjacent track units is controlled to be within 1.5mm; heat insulation layers are set in sections on the supporting base under the tracks to avoid high temperature conduction affecting the track dimensional accuracy; the pool wall integrated equipment 2 used in this embodiment is equipped with two sets of independent temporary cooling air branches and four sets of independent top iron execution units, which can adapt to a larger area of ​​cooling coverage and more points of differentiated clamping; the pool wall integrated equipment 2 is hoisted to the starting end of the track, moved to the first area to be bound with bricks, and then locked in position.

[0020] S2, Combination Figure 3 As shown, temperature detection units 8 are arranged in 4 vertical columns and 1 unit per meter horizontally in the area to be bound with bricks to increase the temperature sampling density; two sets of temporary cooling air branches are started to supply air synchronously. The target air volume flow rate of temporary cooling is calculated and determined according to the heat exchange formula. The target air volume is calculated in real time based on the surface temperature of the pool wall, the effective cooling area and environmental parameters. The actual air volume is controlled by adjusting the fan speed so that the air volume deviation is controlled within ±5%.

[0021] S3. This embodiment adopts a more stringent temperature control standard. The first temperature threshold is 260℃, the second temperature threshold is 320℃, and the temperature rise rate threshold is 3℃ / min. When the regional temperature characteristic value and temperature rise rate meet the operating conditions, the fixed cooling air duct 5 is removed in sections. After removing one section, it is confirmed that the temperature of that section is stable before removing the next section to avoid large-area exposure that could cause a sudden rise in the pool wall temperature. During the removal process, the air volume and air direction of each branch are adjusted in real time to maintain the temperature stability of the entire operating area.

[0022] S4, Combination Figure 4 As shown, the surface morphology data of the old pool wall bricks 3 were collected by three-dimensional scanning to accurately identify the amount of depressions and protrusions in each place; the areas with thick glass deposits were first pre-treated and removed, and then finely polished; the polishing was carried out from top to bottom and from the areas with larger protrusions to the areas with smaller protrusions. After polishing, the overall protrusion was controlled within 0.3 mm. Areas with depressions greater than 2 mm were marked and the depression depth was recorded one by one.

[0023] S5. The omnidirectional robotic arm device 21 adopts a clamping control with gravity compensation. It compensates the clamping force in real time according to the posture change of the new brick 4 to avoid the brick slipping during the posture adjustment process. When planning the path, the conveying path with lower ambient temperature is selected first to reduce the impact of high temperature on the sealing and transmission components of the robotic arm. When the new brick 4 is close to the brick base surface, visual assistance is used for alignment. The horizontal position, vertical position and tilt angle are adjusted in sequence to make the new brick 4 accurately fit the outer surface of the old pool wall.

[0024] S6. Set 5 independent clamping points on the newly laid brick 4, covering the four corners and center of the brick; according to the amount of indentation of the old pool wall corresponding to each point and the initial bonding gap, distribute the target clamping force of each point through a weighted formula. The larger the indentation, the higher the clamping force is allocated to ensure uniform bonding of the brick; the clamping process adopts a graded loading method. First, load synchronously to 60% of the total clamping force, check the gap at each point, and then finely adjust the load point by point to finally control the bonding gap of all points within 0.2 mm; after confirming that the bonding state is qualified, release the mechanical arm clamp and retract it.

[0025] S7. While maintaining the temporary tightening state, reinstall the iron grate 7 and the fixed railing 6. When reinstalling the fixed railing 6, adopt a segmented tightening method to ensure that the railing is subjected to uniform force and to form a stable permanent fixation for the newly laid bricks 4.

[0026] S8. Reinstall the fixed cooling duct 5 and gradually restore the air supply. After restoring the air supply, continuously monitor the pool wall temperature for no less than 15 minutes. After confirming that the temperature is stable within the normal operating range, gradually remove the temporary tightening and temporary cooling.

[0027] S9, Combination Figure 1 As shown, the lock of the pool wall integrated equipment 2 is released, and it automatically moves to the next section along the detachable temporary track 1. Steps 2 to 8 are repeated until all long sections of brick binding work are completed. Multi-level safety interlock control is activated throughout the operation: bricks must not be transported or tightened when the equipment is not locked; fixed air ducts must not be removed when temporary cooling is not up to standard; lifting and transporting must not be done when clamping is not up to standard; clamping must not be released when tightening is not up to standard; temporary tightening must not be released when the railing is not installed; temporary cooling must not be stopped when fixed cooling is not restored; if any abnormal state occurs, the equipment will immediately stop operating and maintain the current safe state, while outputting an alarm signal. Work can only continue after the fault is cleared.

[0028] It should be noted that the directional terms such as "upper," "lower," "both sides," and "ends" used in this article are based on the state shown in the attached drawings and do not constitute a limitation on the actual installation direction. When the installation direction of the device changes, the corresponding positional relationships can be adjusted accordingly.
