Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass production technology, specifically to a stirring mechanism for a glass furnace molten pool. Background Technology
[0002] A glass furnace is a major thermal equipment used to melt glass batches into transparent molten glass at high temperatures. Glass furnaces play a vital role in glass production. By subjecting the mixed glass batches to a series of physicochemical reactions at high temperatures, they ultimately form a uniform and defect-free molten glass for subsequent forming and processing.
[0003] During the glass melting process, the batch material melts in the furnace and undergoes complex physicochemical reactions to form molten glass. However, due to the high viscosity of the molten glass and the different melting points and chemical reaction rates of the components in the batch material, it is easy to cause uneven glass composition and defects such as bubbles. Stirring can promote the homogenization of the molten glass, make the components fully mixed, accelerate the removal of bubbles, and improve the quality of the molten glass.
[0004] Existing glass furnace stirring devices often employ a single stirring method, typically using a single stirring direction. This single stirring direction can easily lead to a fixed flow pattern in the molten glass within the furnace, resulting in insufficient mixing in some areas and uneven composition.
[0005] In view of the above, this application is hereby submitted. Utility Model Content
[0006] The purpose of this invention is to provide a stirring mechanism for the molten pool of a glass furnace to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model provides a glass furnace molten pool stirring mechanism, including a furnace body, a box, fixed lugs and fixed supports. A turntable is rotatably connected to the inner arc wall at the bottom of the box. A driving mechanism is provided inside the box, and the driving mechanism includes:
[0008] A fixed frame is rotatably connected to the center of the top of the turntable. Four telescopic rods arranged in a circular array are fixed on its outer arc wall. A horizontal gear is rotatably connected to the end of the telescopic rod away from the fixed frame. The four gears are respectively meshed with the same incomplete toothed ring on the side away from the fixed frame.
[0009] The limiting frame is fixedly connected to the inner arc wall of the box and located above the fixed frame. The end of the telescopic rod away from the fixed frame is fixed with a slider on the side wall of the limiting frame near the limiting frame. The outer ring of the side wall of the limiting frame near the fixed frame has a first groove and the inner ring has a second groove. The slider slides in the first groove.
[0010] Furthermore, the same limiting groove 1 is provided on the side of the slide 1 and the slide 2 that are close to each other. The limiting groove 1 is arranged in a "snake" shape and is respectively connected to the slide 1 and the slide 2. There are two limiting grooves in total. Both limiting grooves 1 are provided on the side wall of the limiting frame that is close to the fixed frame. The two limiting grooves 1 are respectively provided on both sides of the slide 2. A limiting groove 2 is provided on the inner side wall of the limiting groove 1 that is away from the fixed frame. The limiting groove 2 has a similar cross-sectional shape to the limiting groove 1 in the horizontal direction. The two ends of the limiting groove 2 are respectively connected to the slide 1 and the slide 2.
[0011] Furthermore, two limiting grooves are formed on the side wall of the incomplete toothed ring near the limiting frame. The limiting grooves are inclined and correspond one-to-one with the two limiting slots. Four vertically penetrating sliding channels are formed on the top of the turntable in a circular array about the turntable axis. The four sliding channels correspond one-to-one with the four gears. A fixing rod is fixed on the top of the incomplete toothed ring. The end of the fixing rod away from the incomplete toothed ring is fixed to the limiting frame. The inner arc wall and the outer arc wall of the incomplete toothed ring are provided with evenly distributed teeth. The gears can mesh with the inner and outer sides of the incomplete toothed ring respectively. A second sliding channel is formed at the center of the bottom of the limiting groove. The second sliding channel is vertically penetrating the incomplete toothed ring and its length direction is consistent with the length direction of the limiting groove.
[0012] Furthermore, a rotating shaft is fixedly connected to the bottom of the gear. The end of the rotating shaft away from the gear passes through a sliding channel. A fixing plate is fixed to the end of the rotating shaft away from the gear. A stirring rod is fixed to the side wall of the fixing plate away from the gear. The fixing plate and the stirring rod are both located on the outside of the bottom of the box, i.e. inside the furnace body. The fixing plate and the stirring rod are both made of high-temperature resistant material. The turntable is also made of high-temperature resistant material. The rotating shaft and the sliding channel are compatible. The gear is compatible with the limiting groove.
[0013] Furthermore, the slider fixed to the side wall of the telescopic rod away from the fixed frame and close to the limiting frame slides in the first groove. A placement groove is provided on the side wall of the slider away from the telescopic rod. A fixing block slides in the placement groove. The end of the fixing block close to the limiting frame can slide in the second limiting groove. A return spring is fixed to the end of the fixing block close to the slider. The end of the return spring away from the fixing block is fixed to the inner side wall of the placement groove away from the limiting frame.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By cooperating with the drive mechanism, limit frame, and defective gear, radial displacement of the gear is achieved. This allows the gear to mesh with the teeth on different sides of the defective gear, thereby periodically changing the direction of the stirring rod. This breaks the fixed flow pattern of the molten glass in the molten pool, allowing the molten glass to mix more thoroughly, improving mixing efficiency, and shortening melting time. The periodic direction-changing stirring method allows the ingredients to be more evenly dispersed and heated during the melting process, avoiding agglomeration and helping to improve the overall quality of the molten glass and reduce the generation of defects such as bubbles.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see the appendix Figure 1 To be continued Figure 6 This utility model provides a glass furnace molten pool stirring mechanism, comprising a furnace body 10, a housing 11, fixed lugs 12, and fixed supports 13. A turntable 26 is rotatably connected to the inner arc wall at the bottom of the housing 11. A driving mechanism is provided inside the housing 11, and the driving mechanism includes:
[0029] The fixed frame 20 is rotatably connected to the top center of the turntable 26. Four telescopic rods 21 arranged in a circular array are fixed on its outer arc wall. A horizontal gear 22 is rotatably connected to the end of the telescopic rod 21 away from the fixed frame 20. The four gears 22 are respectively meshed with the same incomplete toothed ring 23 on the side away from the fixed frame 20.
[0030] The limiting frame 30 is fixedly connected to the inner arc wall of the box 11 and is located above the fixed frame 20. The end of the telescopic rod 21 away from the fixed frame 20 is fixed with a slider on the side wall of the limiting frame 30. The outer ring of the side wall of the limiting frame 30 near the fixed frame 20 is provided with a first groove 31 and the inner ring is provided with a second groove 33. The slider slides in the first groove 31.
[0031] The first slide groove 31 and the second slide groove 33 are provided with the same limiting groove 32 on their respective sides. The limiting groove 32 is arranged in a "snake" shape and is respectively connected to the first slide groove 31 and the second slide groove 33. There are two limiting grooves 32 in total. Both limiting grooves 32 are provided on the side wall of the limiting frame 30 near the fixed frame 20. The two limiting grooves 32 are respectively provided on both sides of the second slide groove 33.
[0032] A second limiting groove is provided on an inner side wall of the limiting groove 32 away from the fixing frame 20. The second limiting groove has a similar cross-sectional shape to the first limiting groove 32 in the horizontal direction. The two ends of the second limiting groove are respectively connected to the first sliding groove 31 and the second sliding groove 33.
[0033] A slider fixed to the side wall of the telescopic rod 21 away from the fixed frame 20 and close to the limiting frame 30 slides in the first groove 31. A placement groove is provided on the side wall of the slider away from the telescopic rod 21. A fixing block slides in the placement groove. The end of the fixing block close to the limiting frame 30 can slide in the second limiting groove. A return spring is fixed to the end of the fixing block close to the slider. The end of the return spring away from the fixing block is fixed to the inner side wall of the placement groove away from the limiting frame 30.
[0034] It should be noted that: the length direction of the telescopic rod 21 is consistent with the radial direction of the fixed frame 20, and it can freely extend and retract along the radial direction of the fixed frame 20. A bearing bracket is fixed at the end of the telescopic rod 21 away from the fixed frame 20. A gear 22 rotates inside the bearing bracket. The gear 22 is horizontally set, and the axial direction of the gear 22 is parallel to the axial direction of the fixed frame 20.
[0035] The incomplete toothed ring 23 was originally a complete toothed ring with evenly distributed teeth on its inner and outer arc walls. It is divided into two parts by the limiting groove and the sliding channel. The limiting groove allows the gear 22 to pass through the limiting groove in the horizontal direction along the length of the limiting groove, thereby changing the meshing position of the gear 22 and the incomplete toothed ring 23. The axial height of the gear 22 is less than the axial height of the incomplete toothed ring 23. That is, when the gear 22 moves to the limiting groove, the gear 22 no longer meshes with the inner side of the incomplete toothed ring 23. After passing through the limiting groove, the gear 22 can still mesh with the outer side of the incomplete toothed ring 23.
[0036] When the slider slides in the first groove 31, the gear 22 meshes with the outer side of the broken tooth ring 23. When the slider slides in the second groove 33, the gear 22 meshes with the inner side of the broken tooth ring 23. When the slider slides in the first limiting groove 32, it means that the gear 22 disengages from the broken tooth ring 23 and the gear 22 slides in the limiting groove.
[0037] Furthermore, the width of the second limiting groove is less than the width of the first limiting groove 32, and the width of the fixed block is less than the width of the slider. When the slider slides to the connection between the second limiting groove and the first sliding groove 31 or the second sliding groove 33, the fixed block will pop out and insert into the second limiting groove under the action of the return spring. At this time, the slider will slide into the first limiting groove 32 under the guidance of the fixed block and the second limiting groove, thereby guiding the gear 22 through the limiting groove to change the meshing position.
[0038] Please see the appendix Figure 1 To be continued Figure 6The present invention provides a technical solution: two limiting grooves are provided on the side wall of the incomplete toothed ring 23 near the limiting frame 30. The limiting grooves are inclined and correspond to the two limiting slots 32 respectively. Four vertical sliding channels are provided on the top of the turntable 26 in a circular array about the axis of the turntable 26. The four sliding channels correspond to the four gears 22. A fixing rod is fixed on the top of the incomplete toothed ring 23. The end of the fixing rod away from the incomplete toothed ring 23 is fixed to the limiting frame 30.
[0039] The inner arc wall and the outer arc wall of the defective tooth ring 23 are provided with evenly distributed teeth. The gear 22 can mesh with the inner and outer sides of the defective tooth ring 23 respectively. A sliding channel 2 is provided at the center of the bottom of the limiting groove. The sliding channel 2 is set vertically through the defective tooth ring 23 and its length direction is consistent with the length direction of the limiting groove.
[0040] The bottom of the gear 22 is fixedly connected to a rotating shaft. The end of the rotating shaft away from the gear 22 passes through a sliding channel. A fixing plate 24 is fixed to the end of the rotating shaft away from the gear 22. A stirring rod 25 is fixed to the side wall of the fixing plate 24 away from the gear 22. The fixing plate 24 and the stirring rod 25 are both located on the outside of the bottom of the box 11, i.e. inside the furnace body 10. The fixing plate 24 and the stirring rod 25 are both made of high-temperature resistant material. The turntable 26 is also made of high-temperature resistant material. The rotating shaft and the sliding channel are compatible. The gear 22 is compatible with the limiting groove.
[0041] It should be noted that: a motor is fixed on the top of the box 11, and the output end of the motor passes through the box 11 and is connected to the limiting frame 30. When the motor drives the limiting frame 30 to rotate, it will drive the turntable 26 to rotate through the fixed frame 20. The sliding channel 1 on the turntable 26 is used to accommodate the extension of the telescopic rod 21. Since the fixed frame 20, the telescopic rod 21 and the turntable 26 rotate synchronously, the sliding channel 1 only provides limiting and support for the connection between the gear 22 and the fixed plate 24 and the stirring rod 25.
[0042] Therefore, the radial position of gear 22 relative to turntable 26 is changed periodically. Furthermore, two opposing gears 22 are initially meshed inside the broken tooth ring 23, and the other two opposing gears 22 are initially meshed outside the broken tooth ring 23. The stirring effect is optimized by changing the meshing period through staggered settings. At the same time, the horizontal movement of gear 22 drives the fixed plate 24 and stirring rod 25 to move, thereby stirring the materials in both the inner and outer rings of the furnace body 10, ensuring uniform stirring.
[0043] Several fixed supports 13 are fixed at the bottom of the outer arc wall of the furnace body 10, arranged in a ring array about the axial direction of the furnace body 10. Fixed lugs 12 are fixed at the top of the box body 11, which are used to lift the box body 11 by hoisting equipment after the stirring is completed, so as to facilitate the removal of the stirred material in the furnace body 10.
[0044] Working principle:
[0045] The motor drives the limit frame 30 to rotate, and the fixed frame 20 makes the turntable 26 rotate synchronously. The telescopic rod 21 can extend and retract radially along the fixed frame 20. The slider slides in the first slide groove 31, the second slide groove 33 and the first limit groove 32. The second limit groove and the fixed block drive the gear 22 to mesh and switch inside and outside the broken tooth ring 23. The meshing position of the gear 22 changes, driving the stirring rod 25 to periodically change direction and stir, ensuring that the material in the furnace body 10 is stirred evenly.
