Description

Technical Field

[0001] This utility model relates to an annealing furnace shell, and more particularly to a high-insulation flat glass annealing furnace shell for use in the field of annealing furnaces. Background Technology

[0002] In the production process of float glass, the glass raw material is melted into molten glass at high temperature in a glass melting furnace. The molten glass flows into the tin bath, floats on the surface of the molten tin, and gradually cools to form a glass ribbon. The glass ribbon exits from the tin bath, passes through the slag box, and enters the annealing furnace, where it undergoes the annealing process. Finally, the glass ribbon is cut into glass sheets of specified dimensions. Throughout this process, the glass ribbon is conveyed by a conveyor.

[0003] The existing annealing kilns are mainly in the form of inner and outer frame steel structures and segmented assembly structures. All of these structural forms of annealing kilns are fully assembled products. Not only are the individual product sections large in size and weight, but they also occupy a lot of resources during transportation, transfer and hoisting. Furthermore, if some parts inside the annealing kiln shell are damaged, the entire shell needs to be disassembled and the damaged parts replaced, thereby increasing the operating cost of the annealing kiln. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that the shells of existing annealing kilns are mostly prefabricated products. Not only are the individual product sections large in size and weight, but they also occupy a lot of resources during transportation, transfer and hoisting, thereby increasing the production and transportation costs of annealing kilns.

[0005] To address the aforementioned problems, this utility model provides a high-insulation flat glass annealing furnace shell, comprising multiple base plates and multiple furnace shells located at the upper ends of the base plates. The base plates are welded together. U-shaped mounting brackets are fixedly connected to both ends of the furnace shells. Adjacent mounting brackets are fitted together, and a limiting frame is movably fitted onto the outer surface of both mounting brackets. Multiple receiving grooves are chiseled at both ends of the furnace shells. Multiple locking blocks, each corresponding to a receiving groove, are located at the left end of the furnace shells. The left end of each locking block movably passes through an adjacent receiving groove. Multiple sliding grooves are chiseled on the outer surface of the furnace shells, communicating with the receiving grooves. A sliding plate is fixedly connected to the right end of each locking block, and the sliding plate is located at an adjacent receiving groove. Inside the groove, the end of the sliding plate away from the locking block moves through the adjacent sliding groove. The outer surface of the kiln shell is provided with three pull plates. The left end of the pull plate is fixedly connected to multiple adjacent sliding plates. Both the front and rear ends of the kiln shell are fixedly connected with pressure plates. The ends of the two pressure plates away from each other are provided with positioning plates. The ends of the two positioning plates away from each other are fixedly connected with multiple compression springs. The ends of the two positioning plates away from each other are provided with multiple positioning rods, each corresponding to multiple compression springs. The end of the positioning rod near the compression spring moves through the compression spring and the positioning plate in sequence and is fixedly connected to the bottom plate. The end of the positioning plate away from the compression spring is fixedly connected with multiple insert rods. The end of the insert rod away from the positioning plate moves through the pressure plate and extends into the bottom plate.

[0006] In the aforementioned high-insulation flat glass annealing furnace shell, the previous integral frame structure has been changed, making the annealing furnace shell a detachable structure. The furnace shell parts can be spliced ​​and assembled with each other. The small size of each section can save transportation space, reduce transportation costs, and improve the utilization rate of transportation resources. Furthermore, if the internal parts of the furnace shell are damaged in the future, the individual furnace shell sections can be disassembled to facilitate the replacement of their internal parts.

[0007] As a further improvement of this application, two adjacent kiln shells are fitted together, and the kiln shells are U-shaped, with insulation boards fixedly connected to the inner wall of the kiln shells.

[0008] As a further improvement of this application, the pressure plate is L-shaped as a whole, and the inner wall of the pressure plate is in contact with the outer surface of the base plate.

[0009] As a further improvement of this application, the corresponding ends of the two positioning plates are abutted against the adjacent pressure plate, and the ends of the two positioning plates that are far apart are fixedly connected with handles.

[0010] As another improvement of this application, pull rings are fixedly connected to the four corners of the upper end of the kiln shell, and the pull rings are made of high temperature resistant material.

[0011] In summary, by designing a separate structure for the kiln shell and bottom plate, the previous integral frame structure can be changed, and the parts of the annealing kiln shell can be made into a detachable structure. The entire annealing kiln shell can be installed by splicing and welding on site. Not only are the individual sections smaller, saving transportation space and effectively reducing transportation costs, but the utilization rate of transportation resources can also be improved. In the later stage, individual kiln shell sections can also be disassembled, which facilitates the maintenance of the internal components of the kiln shell and thus effectively reduces maintenance costs.

[0021] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0022] First implementation method:

[0023] Figure 1 and Figure 2The diagram shows a high-insulation flat glass annealing furnace shell, comprising multiple base plates 1 and multiple furnace shells 2 located on the upper ends of the base plates 1. The base plates 1 are welded together, and adjacent furnace shells 2 are fitted together. The furnace shells 2 are U-shaped, and insulation boards 15 are fixedly connected to the inner walls of the furnace shells 2. The insulation boards 15 can effectively improve the heat insulation effect of the furnace shells 2, thereby effectively preventing the external temperature of the furnace shells 2 from being too high. U-shaped mounting brackets 3 are fixedly connected to both ends of the furnace shells 2. Adjacent mounting brackets 3 are fitted together, and the outer surfaces of the two mounting brackets 3 are movably fitted with limiting frames 4. The limiting frames 4 can limit the mounting brackets 3, so that the two furnace shells 2 can be tightly fitted together, effectively preventing external air from entering the interior of the furnace shells 2 through the gaps between the furnace shells 2, and effectively improving the heat insulation and sealing of the interior of the furnace shells 2.

[0024] Figure 3 , Figure 4 and Figure 5 As shown: Multiple receiving grooves 5 are carved at both the left and right ends of the kiln shell 2. Multiple locking blocks 6 are provided at the left end of the kiln shell 2, each corresponding to one of the multiple receiving grooves 5. The left end of the locking block 6 moves through the adjacent receiving groove 5. The locking block 6 is inserted into the adjacent receiving groove 5, which can make the two kiln shells 2 fit tightly together and limit and fix the kiln shell 2. Multiple sliding grooves 7 are carved on the outer surface of the kiln shell 2. The multiple sliding grooves 7 are respectively connected to the multiple receiving grooves 5. The right end of the locking block 6 is fixedly connected to a sliding plate 8. The sliding plate 8 is located in the adjacent receiving groove 5, and the end of the sliding plate 8 away from the locking block 6 moves through the adjacent sliding groove 7. Three pull plates 9 are provided on the outer surface of the kiln shell 2. The left end of the pull plate 9 is fixedly connected to multiple adjacent sliding plates 8. By pulling the pull plate 9, the multiple sliding plates 8 can be moved, thereby moving the multiple locking blocks 6, which effectively improves the installation efficiency.

[0025] Figure 3 and Figure 6As shown: Pressure plates 10 are fixedly connected to both the front and rear ends of the kiln shell 2. Positioning plates 11 are provided at the ends of the two pressure plates 10 that are furthest apart. The pressure plates 10 are L-shaped, and their inner walls are flush with the outer surface of the bottom plate 1. Multiple compression springs 12 are fixedly connected to the ends of the two positioning plates 11 that are furthest apart. The extension and retraction of the compression springs 12 facilitates the movement and resetting of the positioning plates 11. Multiple positioning rods 13 are provided at the ends of the two positioning plates 11 that are furthest apart, each corresponding to one of the compression springs 12. The end of the positioning rod 13 closest to the compression spring 12 passes sequentially through the compression spring 12 and the positioning plate 11, and is fixedly connected to the bottom plate 1. The positioning rod 13 can exert pressure on the compression spring 12. The compression spring 12 and the positioning plate 11 limit the movement of the positioning plate 11, forcing it to move only back and forth. A plurality of insert rods 14 are fixedly connected to the end of the positioning plate 11 away from the compression spring 12. The end of the insert rod 14 away from the positioning plate 11 moves through the pressure plate 10 and extends into the bottom plate 1. The insert rods 14 can limit and fix the pressure plate 10, thereby making the pressure plate 10 fit tightly against the bottom plate 1, and effectively preventing the kiln shell 2 from shaking during use. The corresponding ends of the two positioning plates 11 are in contact with the adjacent pressure plate 10, and the ends of the two positioning plates 11 away from each other are fixedly connected with handles. The handles make it easy to pull the positioning plate 11, effectively improving the installation efficiency.

[0026] When dismantling a single section of the kiln shell 2, the pull plate 9 can be pulled to the right to disengage multiple locking blocks 6 from the receiving groove 5 on the left. Then, the positioning plate 11 is pulled outward. At this time, the compression spring 12 is compressed, the insertion rod 14 is disengaged from the bottom plate 1, and the single section of the kiln shell 2 is in a state of contact with the kiln shells 2 on both sides. At this time, the kiln shell 2 can be pulled upward by the external hoisting structure, which can drive the kiln shell 2 to move upward, thereby disassembling the single section of the kiln shell 2, which facilitates the maintenance of its internal parts.

[0027] Second implementation method:

[0028] This embodiment adds a pull ring 16 to the first embodiment, while the rest remains the same as the first embodiment.

[0029] Figure 7 As shown: Pull rings 16 are fixedly connected to the four corners of the upper end of the kiln shell 2. The pull rings 16 are made of high temperature resistant material.

[0030] When hoisting or disassembling the kiln shell 2, the external hoisting machine can pull the pull ring 16 to move the kiln shell 2 up or down, thereby facilitating the disassembly and assembly of the kiln shell 2 and effectively improving the installation efficiency.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
