Description

Technical Field

[0001] This invention relates to the field of ultra-thin float glass production technology, and in particular to a novel device and method for unblocking the grid of an ultra-thin float glass melting furnace. Background Technology

[0002] Currently, real-time monitoring methods for the regenerator grids in float air kilns are limited. Typically, a decline in combustion efficiency is detected during routine production, or monitoring is conducted intermittently by manually removing the ash removal doors. This fails to achieve real-time monitoring of grid blockages. Furthermore, traditional grid unblocking methods primarily involve manual poking with steel rods, which, while effective for minor blockages, have significant drawbacks: high-temperature and high-risk working environments, extremely low efficiency, high labor intensity, and the risk of shattering already fragile grid bricks, damaging the kiln structure. Therefore, it is crucial to achieve real-time monitoring of grid operation and timely automated unblocking based on blockage conditions to improve combustion efficiency, reduce kiln structural safety risks, and lower operating costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that it is difficult to monitor the blockage status of the grid body in the regenerator of the existing float melting furnace in real time, and manual unblocking operation is risky, inefficient and easy to damage the grid bricks, and cannot achieve automated and precise unblocking.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a novel ultra-thin float glass melting furnace grate unblocking device, including a traveling guide rail, an unblocking component slidably disposed on the traveling guide rail, a supporting guide rail, and a detection device slidably disposed on the supporting guide rail. One end of the traveling guide rail and the supporting guide rail are respectively located below and above the grate. The unblocking component includes a rotating arm for clamping drill rods, a clamping disc for continuously connecting extension rods at the tail end of the drill rods, and a push rod for axially conveying the drill rods. The detection device includes a high-temperature resistant explosion-proof probe arranged vertically downwards.

[0005] Preferably, the traveling rail passes through the ash removal door below the grid body, and a timing belt storage box is installed at the end of the traveling rail away from the grid body. A timing belt is wound on the winding shaft inside the timing belt storage box, and a winding motor that drives the winding shaft to rotate is installed on the side wall of the timing belt storage box. The movable end of the timing belt is connected to the unblocking component, and a timing pulley that meshes with the timing belt is rotatably installed on one side of the timing belt storage box. An encoder is connected to the mounting shaft of the timing pulley.

[0006] Preferably, the unblocking component includes a chassis, with a support wheel and a travel motor at the bottom of the chassis. The output shaft of the travel motor is connected to the mounting shaft of the support wheel. The cross-section of the travel guide rail is inverted T-shaped, and an annular groove adapted to the travel guide rail is formed on the outer side wall of the support wheel.

[0007] Preferably, a transverse sliding guide rail is horizontally arranged on the top of the chassis, and the transverse sliding guide rail is set perpendicular to the traveling guide rail. The transverse sliding guide rail includes a frame, a lead screw rotatably installed inside the frame, a sliding block threaded onto the lead screw, and a sliding motor that drives the lead screw to rotate. The bottom of the sliding block is in contact with the inner bottom surface of the frame. Infrared rangefinders are installed at both ends of the frame. An installation platform is fixed on the top of the sliding block, and the infrared rangefinders are set facing the installation platform. The rotating arm, clamping plate, and push rod are all located on the installation platform.

[0008] Preferably, a support frame is vertically fixed on the mounting platform, and the rotating arm is horizontally rotatably connected to the top of the support frame. A clamp for holding the drill rod is hinged to the movable end of the rotating arm, and a clamping push rod is hinged between the movable end of the clamp and the rotating arm.

[0009] Preferably, a pair of clamps are provided at the top and bottom of the movable end of the rotating arm, and a movable box is axially slidably provided at the movable end of the rotating arm. The movable box is located between the two pairs of clamps. A rod-connecting gear is provided at the end of the movable box facing the outside of the rotating arm. A rod-connecting motor for driving the rod-connecting gear to rotate is installed on the side wall of the movable box. The outer walls of the drill rod and the extension rod are provided with annular toothed grooves. The bottom ends of the drill rod and the extension rod are coaxially provided with threaded holes. The top end of the extension rod is provided with a screw head that matches the threaded hole.

[0010] Preferably, a column is vertically fixed to the top of the installation platform, and the clamping plate is vertically rotatably connected to the top of the column. The edge of the clamping plate has a clamping hole for the extension rod to pass through. A locking rod pusher is installed on the inner side of the clamping plate to press the extension rod into the clamping hole. An arc-shaped mating piece is provided on the side of the clamping hole away from the locking rod pusher. The clamping hole and the locking rod pusher are evenly distributed around the axis of the clamping plate. The movable end of the pusher is connected to a pusher head that matches the threaded hole. The outer diameter of the movable end of the pusher is smaller than the outer diameter of the extension rod.

[0011] Preferably, the support rail is inclined, with the end of the support rail facing outward from the kiln being the top. The detection device includes a sliding sleeve mounted on the support rail and a lifting frame mounted on the sliding sleeve. The high-temperature resistant explosion-proof probe is vertically fixed to the bottom of the lifting frame. A pull rope is connected to the end of the lifting frame. The pull rope is led out from a viewing window on one side above the grid body. The pull rope contains a power line and a signal line.

[0012] Preferably, the cross-section of the support rail is prismatic, the surface of the support rail is provided with a dense ceramic coating, and a supplementary light is fixedly connected to the outside of the high-temperature resistant explosion-proof probe.

[0013] A novel method for unclogging the grate of an ultrathin float glass melting furnace, using the aforementioned unclogging device, includes the following steps: S1. Pull the rope to move the sliding sleeve along the support rail, so that the high temperature explosion-proof probe moves to the top of the target grid hole of the grid body, collects the internal image of the grid hole, identifies the location of the blockage and the degree of nodule formation, and determines the target grid hole to be cleared. S2. Drive the walking motor to move the unblocking component along the trolley guide rail to directly below the target grid hole, and then fine-tune the horizontal position of the installation platform by sliding the horizontal guide rail so that the drill rod is aligned with the target grid hole; S3. The clamping plate clamps the extension rod to be connected via the locking rod push rod. The push rod pushes the extension rod forward, so that the screw head at the top of the extension rod is inserted into the threaded hole at the bottom of the upper rod. The clamp is released, and the moving box is driven to move, so that the connecting rod gear meshes with the tooth groove on the outer wall of the upper rod. The locking rod push rod keeps the lower extension rod locked, and the connecting rod motor drives the connecting rod gear to rotate the upper rod, completing the threaded locking connection between the extension rod and the upper rod. After the connection is completed, the push rod continues to push forward, driving the assembled drill rod assembly to feed upward along the grid hole. After the drill rod is fed into place, the clamp re-clamps the drill rod, preparing for the continuation of the next extension rod connection. S4. The drill rod continues to feed upwards to drill and break up the nodules of Glauber's salt in the grid holes. After a single grid hole is cleared, the drill rod is retracted and the extension rod is disassembled in sequence. The position of the clearing components and the detection device is adjusted. Steps S1 to S3 are repeated to complete the detection and clearing of the remaining blocked grid holes in sequence. S5. The nodule residue that falls off during drilling falls to the sedimentation chamber by gravity and is then removed through the ash removal door (2).

[0014] This invention provides a novel device and method for unblocking the grid of an ultra-thin float glass melting furnace, which has the following beneficial effects.

[0015] 1. This invention features a movable detection device that uses a high-temperature resistant and explosion-proof probe to visualize and detect the grid holes inside the grid body in real time. It can accurately identify the location and degree of grid hole blockage, which changes the shortcomings of traditional methods that rely on manual experience and kiln pressure parameters for indirect judgment and cannot be monitored at fixed points. It achieves accurate and visualized prediction of the grid body blockage status, providing accurate data support for targeted dredging operations.

[0016] 2. This invention adopts an automated track-type dredging structure, which can achieve multi-dimensional precise positioning by relying on the trolley guide rail and the transverse sliding guide rail, replacing the traditional manual operation of holding a steel bar to poke and tamp at high temperatures, completely avoiding the high-temperature and high-risk working environment, greatly reducing the intensity of manual labor, and improving the safety and efficiency of operation.

[0017] 3. This invention features an automatic rod docking mechanism. Through the clamping disc, locking rod push rod, and connecting rod gear working in conjunction with the top push rod, it achieves automatic threaded docking, step-by-step length extension, and stable feeding of the extension rod and drill rod. The rod docking accuracy is high, and the feeding is stable. It can be adapted to the full-height dredging operation of grid bodies with a height of 8 to 9 meters, solving the problems of cumbersome operation and large alignment deviation in traditional segmented manual rod docking.

[0018] 4. This invention adopts a mechanically controllable drilling and dredging method. Compared with the traditional brute force steel chisel tamping, the working force is controllable and the alignment is precise. It can accurately break the hardened nodules of Glauber's salt in the grid holes, while avoiding hard impact damage to the fragile grid bricks. It effectively protects the kiln refractory structure, reduces the safety hazards of kiln damage and air leakage, and extends the service life of the melting kiln.

[0019] 5. The overall equipment of this invention relies on the existing ash removal door and upper viewing window arrangement, without the need to modify the kiln body. It can realize online uninterrupted kiln unblocking, effectively ensuring the heat exchange efficiency of the regenerator and the combustion stability of the melting furnace, reducing the problems of increased kiln pressure, decreased air temperature and fluctuations in glass production quality caused by grid blockage, and reducing the operating and cold repair costs of the kiln.

[0027] like Figures 1 to 6 As shown, this invention provides a novel device and method for unblocking the grid of an ultra-thin float glass melting furnace. It is mainly applied to the online detection and unblocking of the grid 1 in the regenerator chamber of an ultra-thin float glass melting furnace. The device comprises a traveling guide rail 3 positioned below, an unblocking component 4 slidably mounted on the traveling guide rail 3, a support guide rail 5 inclinedly positioned above the grid 1, and a detection device 6 slidably mounted on the support guide rail 5. The traveling guide rail 3 passes through the ash removal door 2 below the grid 1, with one end extending below the working area of ​​the grid 1. The support guide rail 5 extends one end to the working area above the grid 1, enabling precise movement and alignment of the unblocking mechanism below and visual detection of the blockage status of the grid holes above. This allows for online unblocking operations without modifying the furnace structure.

[0028] like Figure 1 As shown, the traveling guide rail 3 adopts an inverted T-shaped cross-section structure, which has strong adaptability to movement and high load-bearing stability. A synchronous belt storage box 8 is fixedly installed at the end of the traveling guide rail 3 away from the grid body 1. A winding shaft is rotatably installed inside the synchronous belt storage box 8, and the synchronous belt is wound on the winding shaft. A winding motor that drives the winding shaft to rotate is installed on the side wall of the synchronous belt storage box 8. The movable end of the synchronous belt is fixedly connected to the unblocking component 4. At the same time, a synchronous pulley 9 that meshes with the synchronous belt is rotatably installed on one side of the synchronous belt storage box 8. The mounting shaft of the synchronous pulley 9 is connected to an encoder. During operation, the encoder can record the travel distance of the synchronous belt in real time, accurately feedback the movement position of the unblocking component 4, and realize automated and precise positioning.

[0029] like Figure 1 and Figure 2As shown, the unblocking component 4 includes a chassis 10. Support wheels 11 and a travel motor 12 are mounted on the bottom of the chassis 10. The outer wall of the support wheels 11 has an annular groove adapted to the inverted T-shaped trolley guide rail 3. The output shaft of the travel motor 12 is connected to the support wheels 11, driving the chassis 10 to move stably back and forth along the trolley guide rail 3, thus achieving longitudinal position adjustment. A transverse sliding guide rail 13 is horizontally fixed on the top of the chassis 10. The transverse sliding guide rail 13 is arranged perpendicularly to the trolley guide rail 3 and consists of a frame, a lead screw, a sliding block, and a sliding motor. The lead screw is rotatably mounted inside the frame, and the sliding block is threaded onto the outside of the lead screw, with its bottom fitting against the inner bottom surface of the frame to ensure sliding stability. Infrared rangefinders 28 are installed at both ends of the frame. A mounting platform 14 is fixedly mounted on the top of the sliding block, with the infrared rangefinders 28 facing the mounting platform 14. This allows for real-time detection of the transverse sliding distance, precise control of the transverse position of the mounting platform 14, and multi-dimensional precise alignment of the drill rod 24 with the grid holes.

[0030] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a support frame 15, a column 22, and a push rod 29 are fixedly mounted on the installation platform 14. A rotating arm 16 is horizontally rotatably connected to the top of the support frame 15. Pairs of clamps 17 are mounted on the upper and lower sides of the movable end of the rotating arm 16. The clamps 17 are used to clamp and fix the drill rod 24. A clamping push rod 18 is hinged between the movable end of the clamp 17 and the rotating arm 16. By extending and retracting the clamping push rod 18, the clamps 17 can be clamped and released, thus fixing and releasing the drill rod 24. The clamping push rod 18 is an electric push rod. A movable box 19 is also axially slidably mounted on the movable end of the rotating arm 16. The movable box 19 is located between the two sets of clamps 17. A rod-connecting gear 21 is mounted on the outside of the movable box 19, and a rod-connecting motor 20 is fixed to the side wall. The rod-connecting motor 20 can drive the rod-connecting gear 21 to rotate. An electric push rod is installed inside the rotating arm 16 to drive the movable box 19 to move. Both the drill rod 24 and the extension rod 25 have annular toothed grooves 27 on their outer side walls and threaded holes coaxially at their bottom ends. The extension rod 25 has a matching screw head at its top end. Through the meshing transmission between the connecting gear 21 and the toothed grooves 27, the rods can be rotated and connected.

[0031] like Figure 2 and Figure 4As shown, a clamping disk 23 is vertically rotatably connected to the top of the column 22. A stepper motor is installed on the top of the outer wall of the column 22. A drive gear is installed on the output shaft of the stepper motor. A driven gear is fixed on the mounting shaft of the clamping disk 23. The drive gear and the driven gear mesh with each other and can drive the clamping disk 23 to rotate through the stepper motor. Several clamping holes 31 are evenly opened on the edge of the clamping disk 23 for passing through the positioning extension rod 25. A locking rod push rod 33 is installed on the inner side of the clamping disk 23 corresponding to each clamping hole 31. An arc-shaped docking piece 32 is fixed on the inner wall of the clamping hole 31. The extension rod 25 can be pressed and fixed inside the clamping hole 31 by the extension and retraction of the locking rod push rod 33, so as to realize the positioning and locking of the extension rod 25 and ensure the docking stability. The movable end of the push rod 29 is fixed with the push head 30. The push head 30 is adapted to the threaded hole at the bottom of the rod. The outer diameter of the movable end of the push rod 29 is smaller than the outer diameter of the extension rod 25. It can pass through the clamping hole 31 to effectively push the extension rod 25, which is suitable for the step-by-step feeding operation of the rod.

[0032] like Figure 1 and Figure 3 As shown, the support rail 5 above the grid body 1 adopts a prismatic cross-section design, which has strong structural stability. The surface of the support rail 5 is coated with a dense ceramic coating, which is resistant to high temperatures, corrosion, and scaling, effectively resisting the high temperature and alkaline salt steam erosion of the regenerator and preventing the adhesion of sodium sulfate nodules to the rail surface, thus avoiding affecting the sliding accuracy. The support rail 5 is inclined, with the end facing the outside of the kiln as the top, facilitating the disassembly and maintenance of the detection device 6. The detection device 6 includes a sliding sleeve 35 and a lifting frame 34. The sliding sleeve 35 is slidably fitted onto the support rail 5, and the lifting frame 34 is fixed to the bottom of the sliding sleeve 35. A high-temperature explosion-proof probe 36 is vertically fixed to the bottom of the lifting frame 34. A supplementary light 37 is mounted on the outside of the high-temperature explosion-proof probe 36, which can supplement the light inside the high-temperature and dimly lit grid holes, improving imaging clarity and accurately collecting images of nodules and blockages inside the grid holes. The end of the hoisting frame 34 is connected to a pull rope 38, which is led out from the viewing window 7 above the grid body 1. The pull rope 38 integrates power and signal lines, which can not only power the probe and transmit image signals, but also drive the sliding sleeve 35 to slide along the support rail 5 by pulling the pull rope 38, so as to flexibly adjust the detection position.

[0033] The specific dredging operation process of this invention is as follows: S1. Detection and positioning: During operation, the staff pulls the rope 38 to move the sliding sleeve 35 along the inclined support rail 5, so as to accurately move the high temperature and explosion-proof probe 36 to the target grid hole of the grid body 1. The supplementary light 37 is turned on to supplement the light. The high temperature and explosion-proof probe 36 collects real-time images of the inside of the grid hole, clearly identifies the location of the blockage, the thickness of the nodule and the degree of blockage, and accurately locates the target grid hole to be cleared, thus eliminating the drawbacks of traditional experience-based and indirect judgment.

[0034] S2. For unblocking and alignment, start the travel motor 12 to drive the support wheel 11 to travel along the trolley guide rail 3, moving the entire unblocking assembly 4 to directly below the target grid hole. Combined with the stroke feedback of the encoder, precise longitudinal positioning is achieved. Then, start the sliding motor to drive the lead screw to rotate, causing the sliding block and the top mounting platform 14 to move laterally. With the distance measurement and calibration of the infrared rangefinder 28, the horizontal position of the drill rod 24 is finely adjusted to ensure that the drill rod 24 is precisely coaxially aligned with the target grid hole, ensuring the accuracy of subsequent unblocking operations.

[0035] S3. Stepwise feed: In the initial state, clamp 17 clamps and fixes drill rod 24, and clamping disc 23 locks extension rod 25 to be connected via locking rod push rod 33; start push rod 29 to extend upward, pushing extension rod 25 upward, so that the screw head at the top of extension rod 25 is inserted into the threaded hole at the bottom of upper drill rod 24. Then control clamping push rod 18 to retract, releasing clamp 17 while maintaining the limit on drill rod 24, drive moving box 19 to slide, so that connecting rod gear 21 precisely meshes with the tooth groove 27 on the outside of drill rod 24; keep locking rod push rod 33 locking lower extension rod 25, start connecting rod motor 20 to drive connecting rod gear 21 to rotate, driving upper drill rod 24 to rotate synchronously, realizing threaded locking connection between extension rod 25 and drill rod 24. After the rods are connected, the push rod 29 is driven again to push forward continuously, causing the assembled rod assembly to be fed vertically upward smoothly along the grid holes. After the rod is fed to the preset position, the clamp 17 is controlled to clamp and fix the rod again, the locking rod push rod 33 releases the extension rod 25, resets the clamping plate 23, and prepares for the continuation of the next extension rod 25. Through step-by-step connection and extension, it can meet the dredging needs of the entire grid body 1 with a height of 8 to 9 meters.

[0036] S4. Drilling and Circulation Operation: During the continuous upward feeding of the rod, the hardened nodules inside the grid holes are mechanically drilled and scraped by the top of the rod, precisely breaking up the blockages. Compared with traditional manual brute force, the force is controllable and the alignment is precise, effectively avoiding cracking and damage to the grid bricks. After the single target grid hole is cleared, the push rod 29 is retracted, the extension rod 25 is disassembled step by step, and the drill rod 24 is retracted. Then, the positions of the detection device 6 and the clearing component 4 are adjusted again, and the above detection, alignment, rod docking, and drilling and clearing steps are repeated to complete the clearing operation of all blocked grid holes in the grid body 1.

[0037] S5. Drilling and scraping off the detached Glauber's salt nodules and fragments, which automatically fall and collect in the settling chamber below the grid body 1 under the action of gravity. After all grid holes are cleared, the staff can directly clean and transport the residue in the settling chamber through the ash removal door 2. The operation is convenient and leaves no residue.

Pull the pull rope (38) to move the sliding sleeve (35) along the support rail (5) so that the high temperature explosion-proof probe (36) moves to the top of the target grid hole of the grid body (1), collect the internal image of the grid hole of the grid body (1), identify the blockage location and degree of nodule, and determine the target grid hole to be cleared. S2. Drive the walking motor (12) to move the unblocking component (4) along the trolley guide rail (3) to directly below the target grid hole, and then finely adjust the horizontal position of the installation platform (14) through the transverse sliding guide rail (13) so that the drill rod (24) is aligned with the target grid hole; S3. The clamping plate (23) clamps the extension rod (25) to be connected through the locking rod push rod (33). The push rod (29) pushes the extension rod (25) forward so that the screw head at the top of the extension rod (25) is inserted into the threaded hole at the bottom of the upper rod. The clamp (17) is released and the moving box (19) is driven to move so that the connecting rod gear (21) meshes with the tooth groove (27) on the outer wall of the upper rod. The locking rod push rod (33) is kept to lock the lower extension rod (25). The connecting rod motor (20) drives the connecting rod gear (21) to rotate the upper rod and complete the threaded locking docking of the extension rod (25) and the upper rod. After docking, the push rod (29) continues to push forward, driving the assembled drill rod (24) assembly to feed upward along the grid hole. After the drill rod (24) is fed into place, the clamp (17) re-clamps the drill rod (24) to prepare for the continuation of the next extension rod (25). S4. The drill rod (24) continues to feed upward to drill and break up the nodules of Glauber's salt in the grid holes. After the single grid hole is cleared, the drill rod (24) is retracted and the extension rod (25) is disassembled in sequence. The positions of the clearing component (4) and the detection device (6) are adjusted. Steps S1 to S3 are repeated to complete the detection and clearing of the remaining blocked grid holes in sequence. S5. The nodule residue that falls off during drilling falls to the sedimentation chamber by gravity and is then collected and removed through the ash removal door (2).
