Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass production equipment technology, and in particular to a sealing device and an annealing furnace. Background Technology
[0002] Annealing furnaces are essential equipment in the glass production process. After the glass sheets are formed in the tin bath, they are drawn onto the annealing furnace via roller conveyors and pass through different sections of the furnace in sequence, so that the internal stress of the glass sheets is gradually reduced in a controlled manner, thereby achieving the purpose of annealing.
[0003] During the annealing and cooling process, glass may break apart due to temperature fluctuations or other reasons. If the glass fragments break apart in the annealing furnace and are stuck or stood upright by the roller conveyor or baffle, the glass will be unable to move forward smoothly, causing blockage in the annealing furnace and resulting in a serious production accident.

[0029] This utility model proposes a sealing device and an annealing furnace. The purpose is to allow the sealing component to be removably installed in the mounting hole, and the entire sealing component can be quickly and conveniently removed from the annealing furnace shell by means of a handle. This allows the staff to quickly check the condition inside the annealing furnace and clean up the broken glass inside, so as to quickly resume production. The sealing component is pressed against the inner peripheral wall of the mounting hole to ensure the overall sealing and heat preservation of the annealing furnace.
[0030] Please see Figures 1 to 4 In one embodiment of this utility model, the sealing device 100 includes:
[0031] Two sealing components 1 are removably installed in the mounting holes 31 and are positioned opposite each other on both sides of the roller conveyor 4 to form through holes 15 for the roller conveyor 4 to pass through. One end of the roller conveyor 4 is rotatably connected to the annealing kiln shell 3, and the other end of the roller conveyor 4 passes through the through holes 15 and extends out of the annealing kiln shell 3, and is rotatably connected to the outer wall of the annealing kiln shell 3.
[0032] A handle 2 is provided on one side of the sealing assembly 1 and is used to remove the sealing assembly 1 along the axial direction of the roller conveyor 4.
[0033] As is known, the annealing furnace shell 3 is provided with mounting holes 31 for the roller conveyor 4 to pass through, and one side of the roller conveyor 4 passes through the mounting holes 31 and extends out of the annealing furnace shell 3. One end of the roller conveyor 4 is rotatably connected to the inner side wall of the annealing furnace shell 3, and the other end of the roller conveyor 4 passes through the mounting holes 31 and extends out of the annealing furnace shell 3, and is rotatably connected to the outer wall of the annealing furnace shell 3 to transport glass plates. It should be noted that two support structures are provided on the two outer side walls of the shell, and the two ends of the roller conveyor 4 are rotatably mounted on the support structures respectively. It should be further noted that the support structures are prior art, and this application does not limit them in any way.
[0034] The sealing device 100 includes a sealing component 1 and a handle 2. The two sealing components 1 are removably installed in the mounting hole 31 and are positioned opposite each other on both sides of the roller conveyor 4 to form a through hole 15 for the roller conveyor 4 to pass through. The handle 2 is located on one side of the sealing component 1 and is used to remove the sealing component 1 along the axial direction of the roller conveyor 4. Thus, the sealing component 1 can be smoothly pulled out or pushed in from the mounting hole 31 through the handle 2, and the roller conveyor 4 passes through the through hole 15 in sequence. Thus, while the mounting hole 31 is blocked by the sealing component 1, the normal operation of the roller conveyor 4 can also be ensured. When the sealing component 1 is removed from the mounting hole 31 through the handle 2, the mounting hole 31 can be opened, and the staff can quickly check the condition inside the annealing furnace 200 and clean up the broken glass inside, and quickly resume production.
[0035] In one implementation, please refer to Figures 1 to 3 Each of the sealing components 1 includes a sealing element 11 and a first clamping plate 12 and a second clamping plate 13 spaced apart. A clamping space 16 is formed between the first clamping plate 12 and the second clamping plate 13. The sealing element 11 is disposed in the clamping space 16. The handle 2 is disposed on the side of the first clamping plate 12 away from the sealing element 11. By clamping the sealing element 11 between the first clamping plate 12 and the second clamping plate 13, the structural stability of the sealing element 11 is ensured.
[0036] In this embodiment, in order to ensure that the temperature inside the annealing furnace shell 3 is not affected, the sealing assembly 1 includes a sealing element 11 and a first clamping plate 12 and a second clamping plate 13 spaced apart. A clamping space 16 is formed between the first clamping plate 12 and the second clamping plate 13. The sealing element 11 is disposed in the clamping space 16, and the handle 2 is disposed on the side of the first clamping plate 12 away from the sealing element 11. That is, when the worker takes the sealing assembly 1 out of the mounting hole 31 by lifting the handle, the sealing element 11 is pulled out together with the first clamping plate 12 and the second clamping plate 13 or pushed into the mounting hole 31 together. This arrangement makes the disassembly and installation of the sealing assembly 1 quick and convenient, thereby reducing the loss when the annealing furnace 200 explodes and becomes blocked.
[0037] In one implementation, please refer to Figure 2 and Figure 3 The first clamping plate 12 has a first through hole 121, the second clamping plate 13 has a second through hole 131, and the sealing member 11 has a third through hole 111. The roller conveyor 4 passes through the second through hole 131, the third through hole 111 and the first through hole 121 in sequence. In this way, while ensuring the sealing and heat preservation functions of the sealing component 1, the normal operation of the roller conveyor 4 is also ensured.
[0038] In this embodiment, in order to facilitate the connection between the seal 11 and the roller conveyor 4, a first through hole is provided in the first clamping plate 12, the second clamping plate 13 is provided in the second through hole 131, and a third through hole 111 is provided in the seal 11. Therefore, after the seal 11 is pushed into the mounting hole 31, the roller conveyor 4 passes through the second through hole 131, the third through hole 111 and the first through hole 121 in sequence, and then passes out of the mounting hole 31. This arrangement ensures that each part works normally without being affected.
[0039] In one implementation, please refer to Figure 2 The cross-sectional area of the second through hole 131 is larger than that of the first through hole 121, and the cross-sectional area of the first through hole 121 is larger than that of the third through hole 111. The roller conveyor 4 is configured in such a way that the surface of the roller conveyor 4 is not easily scratched when the sealing component 1 is removed from the mounting hole 31.
[0040] In this embodiment, in order to ensure that the sealing component 1 will not scratch the surface of the roller conveyor 4 when it is removed, the cross-sectional area of the second through hole 131 is larger than the cross-sectional area of the first through hole 121, and the cross-sectional area of the first through hole 121 is larger than the cross-sectional area of the third through hole 111. Furthermore, the diameter of the third through hole 111 is equal to the diameter of the roller conveyor 4. Thus, when the sealing component 1 is removed from the mounting hole 31, since the diameters of the first through hole 121 and the second through hole 131 are both larger than the diameter of the roller conveyor 4, it is less likely that the first clamping plate 12 and the second clamping plate 13 will collide with the roller conveyor 4, thereby preventing scratches on the surface of the roller conveyor 4.
[0041] In one implementation, please refer to Figure 2 and Figure 3 The first through hole 121, the second through hole 131, and the third through hole 111 are semi-circular in shape. Thus, two opposite first through holes 121 form a circular hole, two opposite second through holes 131 form a circular hole, and two opposite third through holes 111 form a circular hole. That is, the through hole 15 is circular in shape. This arrangement makes the through hole 15 fit the shape of the roller conveyor 4 so that the roller conveyor 4 can smoothly pass through the second through hole 131, the third through hole 111, and the first through hole 121, and then pass out of the mounting hole 31, and is less likely to scratch the surface of the roller conveyor 4.
[0042] In one implementation, please refer to Figure 2 and Figure 3The cross-sectional area of the first clamping plate 12 is larger than the cross-sectional area of the mounting hole 31, the cross-sectional area of the second clamping plate 13 is smaller than the cross-sectional area of the mounting hole 31, and the cross-sectional area of the sealing element 11 is equal to the cross-sectional area of the mounting hole 31. This arrangement ensures that the sealing element 11 can press against the inner peripheral wall of the mounting hole 31 to achieve a certain sealing and heat preservation effect.
[0043] In this embodiment, in order to ensure the connection between the first clamping plate 12 and the second clamping plate 13 and the annealing furnace shell 3, the cross-sectional area of the first clamping plate 12 is set to be larger than the cross-sectional area of the mounting hole 31, and the cross-sectional area of the second clamping plate 13 is smaller than the cross-sectional area of the mounting hole 31. That is, the second clamping plate 13 and the sealing member 11 are pushed into the mounting hole 31, while the first clamping plate 12 is blocked on the outer edge of the mounting hole 31 to play a certain positioning and sealing role, thereby effectively preventing the entire sealing assembly 1 from falling into the annealing furnace shell 3 through the mounting hole 31, so as to ensure that the entire sealing assembly 1 can be stably placed in the mounting hole 31.
[0044] Meanwhile, to ensure that the sealing element 11 can always press against the inner peripheral wall of the mounting hole 31, the cross-sectional area of the sealing element 11 is equal to the cross-sectional area of the mounting hole 31. Of course, the cross-sectional area of the sealing element 11 can also be slightly larger than the cross-sectional area of the mounting hole 31 to ensure that the sealing element 11 can press against the inner peripheral wall of the mounting hole 31. Furthermore, the cross-sectional area of the sealing element 11 is set to be larger than the cross-sectional area of the second clamping plate 13, that is, the sealing element 11 protrudes from the second clamping plate 13, while the cross-sectional area of the first clamping plate 12 is... The area is greater than the cross-sectional area of the seal 11. Therefore, when the second clamping plate 13 and the seal 11 are pushed into the mounting hole 31, the outer peripheral wall of the seal 11 can be stably pressed against the inner peripheral wall of the mounting hole 31. Furthermore, the first clamping plate 12 is blocked on the outer edge of the mounting hole 31. In this way, while the first clamping plate 12 and the second clamping plate 13 can stably clamp the seal 11, it can also effectively ensure that the seal 11 can be pressed against the inner peripheral wall of the mounting hole 31, thereby playing the role of heat preservation and sealing.
[0045] In one implementation, please refer to Figure 4 The sealing element 11 is thermal insulation cotton. Thus, the thermal insulation cotton has a certain degree of elasticity. When the sealing element 11 is pushed into the mounting hole 31, due to the elasticity of the sealing element 11, it can stably press against the inner peripheral wall of the mounting hole 31 to achieve a certain sealing effect and thermal insulation effect.
[0046] In one implementation, please refer to Figure 2 and Figure 3The sealing assembly 1 further includes connectors 14, and multiple connectors 14 are provided. The multiple connectors 14 are spaced apart between the first clamping plate 12 and the second clamping plate 13 to connect the first clamping plate 12, the second clamping plate 13 and the sealing member 11. By providing multiple connectors 14, the first clamping plate 12, the second clamping plate 13 and the sealing member 11 are further stably connected together to improve the connection stability among the three.
[0047] In this embodiment, in order to further ensure the firm connection between the first clamping plate 12, the second clamping plate 13 and the sealing member 11, the sealing assembly 1 also includes a connector 14, and there are multiple connectors 14. The multiple connectors 14 are spaced apart between the first clamping plate 12 and the second clamping plate 13 to lock the sealing member 11 in the clamping space 16, thereby ensuring that the sealing member 11 can move with the movement of the first clamping plate 12 and the second clamping plate 13. This arrangement makes the disassembly and installation of the sealing assembly 1 quick and convenient, thereby reducing the loss when the annealing furnace 200 explodes and becomes blocked.
[0048] It should be noted that the connector 14 can be a combination of bolts and nuts, or other fasteners, which are not limited in this application.
[0049] In one implementation, please refer to Figure 2 and Figure 3 The lifting handle 2 is provided in multiple ways, and the multiple lifting handles 2 are spaced apart from the first clamping plate 12. By providing multiple lifting handles 2, the sealing component 1 can be easily taken out from the mounting hole 31, which is convenient for operation.
