Description

Technical Field

[0001] This application relates to the field of glass production equipment technology, and in particular to a cover plate control device and a glass furnace. Background Technology

[0002] In the glass manufacturing industry, nanocrystalline glass is a composite glass composed of various elements such as silicates and borates. Compared with ordinary glass, it has a higher degree of crystallinity and advantages such as high transparency, high hardness, impact resistance, and high temperature resistance. During the melting process of nanocrystalline glass, it is necessary to conduct on-site observation and judgment of the internal environment of the furnace, the corrosion of the refractory materials, the burner, the condition of the refractory material pile and its flame operation, liquid level changes, and the size and frequency of bubbles.

[0003] Current methods for observing kilns involve sealing the observation port with refractory bricks during production. When observation of the kiln's interior is needed, the refractory bricks are removed. This process is cumbersome, difficult to operate, and the high temperature of the bricks can easily burn operators. Furthermore, due to prolonged exposure to high temperatures and corrosion from glass materials, the refractory bricks are prone to deformation, sometimes even becoming jammed. This necessitates partial removal of the observation port, a time-consuming, labor-intensive, dangerous process that can damage the kiln structure. Utility Model Content

[0025] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0026] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0027] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments.

Moreover, the term "at least one" in this application means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C. Furthermore, the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0029] During the melting process of nanocrystalline glass, it is necessary to observe the interior of the furnace to ensure that the furnace maintains a suitable melting environment. However, existing furnace observation methods require operators to seal the observation port with refractory bricks. When observation is needed, the refractory bricks must be removed from the observation port. This process is cumbersome, difficult to operate, and the high temperature of the bricks can easily burn the operators. Furthermore, due to prolonged exposure to high temperatures and corrosion from the glass raw materials, the refractory bricks are prone to deformation, and in severe cases, they can become stuck. This necessitates the removal of the observation port, a time-consuming, labor-intensive, dangerous process that can damage the furnace structure.

[0030] Based on the above issues, please refer to Figure 1 , Figure 1 This is a first-view structural schematic diagram of an embodiment of the cover plate control device of this application. This application provides a cover plate control device 1, which is used to open or close the observation port 21 of the kiln, so that the user does not need to manually remove and pile up the bricks at the observation port 21 of the kiln, thereby reducing the user's work difficulty and improving the user's observation efficiency.

[0031] The cover plate control device 1 includes a cover plate 11, a lifting mechanism 12, and a fastening mechanism 13. The cover plate 11 is rotatably mounted at the observation port 21 and configured to have a first state of rotating relative to the observation port 21 to open it, and a second state of being closed by covering the observation port 21. The lifting mechanism 12 is mounted on the side wall 2 of the kiln and connected to one end of the cover plate 11. The lifting mechanism 12 can pull the cover plate 11 to rotate relative to the observation port 21, switching the cover plate 11 from the second state to the first state, thus opening the observation port 21. This allows users to open the observation port by pulling the cover plate through the lifting mechanism when they need to observe the interior of the kiln, reducing the difficulty of opening the observation port, improving safety, and enhancing the user experience of the cover plate control device 1.

[0032] The fastening mechanism 13 is installed on the side wall 2 of the kiln, with one end abutting against the cover plate 11, for fixing the cover plate 11 in the second state. This prevents the high temperature inside the kiln from causing gas expansion and applying a force away from the observation port 21 to the cover plate 11, resulting in a gap between the cover plate 11 and the observation port 21, which would prevent sealing the inside of the kiln and affect the holding efficiency of the nanocrystalline glass in the kiln. Furthermore, since the inside of the kiln is exposed, high-temperature materials inside the kiln may splash out through the observation port 21 during the melting process, affecting the safety of personnel around the kiln. This application, by setting the fastening mechanism 13 to fix the cover plate 11 in the second state, improves the melting efficiency of the kiln while enhancing the safety of the melting process, further improving the user experience of the cover plate control device 1.

[0033] In one embodiment, one end of the fastening mechanism 13 can be disposed on the side of the cover plate 11 away from the observation port 21 and abut against the surface of the cover plate 11. The extending direction of one end of the fastening mechanism 13 can be perpendicular to the abutting surface, thereby providing a force to the cover plate 11 near the observation port 21 to fix the cover plate 11 in the second state. In another embodiment, the extending direction of one end of the fastening mechanism 13 can also be parallel to the abutting surface, etc., to provide a force to the cover plate 11 near the observation port 21.

[0034] It is understandable that, compared to one end of the fastening mechanism 13 being at other angles to the abutting surface, the extension direction of one end of the fastening mechanism 13 being perpendicular to the abutting surface can provide the cover plate 11 with a greater force to approach the observation port 21. Therefore, in this embodiment, it is preferable that one end of the fastening mechanism 13 is perpendicular to the surface of the cover plate 11.

[0035] In this application, when the fastening mechanism 13 fixes the cover plate 11 in the second state, the specific contact direction of one end of the fastening mechanism 13 is not restricted.

[0036] Optionally, such as Figure 1 As shown, the lifting mechanism 12 provided in this application embodiment includes a first support frame 121, at least one synchronous pulley 122 and a pull rope 123.

[0037] The first support frame 121 is mounted on the side wall 2 of the kiln where the observation port 21 is located, and at least one synchronous wheel 122 is mounted on the first support frame 121. Figure 1 As shown, when there are two or more synchronous pulleys 122, the two or more synchronous pulleys 122 are spaced apart along the extension direction of the first support frame 121. In the vertical direction, the first support frame 121 and at least one synchronous pulley 122 are located above the observation port 21. One end of the pull rope 123 passes through the wheel surface of the synchronous pulley 122 and is connected to the cover plate 11. The user can then pull the cover plate 11 to rotate by pulling the rope 123. The user provides a force against the weight of the cover plate 11 by pulling the rope 123, thereby opening the observation port 21. After the user has finished observing the inside of the kiln, the user can release the pull rope 123. The force against the weight of the cover plate 11 provided by the pull rope 123 disappears, and the cover plate 11 can be repositioned on the observation port 21 under its own weight.

[0038] The pull rope 123 can be a steel wire rope to improve its stability and reduce maintenance costs. The radial cross-section of the first support frame 121 can be U-shaped to increase its rigidity and improve the stability of the lifting mechanism 12.

[0039] By placing the first support frame 121 and the synchronous wheel 122 above the observation port 21, the gravity of the cover plate 11 itself can be utilized during the state switching process. There is no need to set up an additional structure to switch the cover plate 11 from the first state to the second state. The cover plate 11 can switch from the first state to the second state under its own gravity, which simplifies the setting structure of the cover plate control device 1, reduces the manufacturing cost of the cover plate control device 1, and improves the user's experience of using the cover plate control device 1.

[0040] In one embodiment, the synchronizing pulley 122 can be a V-shaped pulley, a U-shaped pulley, etc. In practical applications, since the contact between the V-shaped pulley and the pull rope 123 is a line contact, while the contact between the U-shaped pulley and the pull rope 123 is a surface contact, that is, during the transmission of the pull rope 123, the frictional force of the V-shaped pulley on the pull rope 123 is greater than that of the U-shaped pulley on the pull rope 123. Therefore, the synchronizing pulley 122 in this embodiment is preferably a U-shaped pulley.

[0041] Optionally, please refer to the following: Figure 2 , Figure 2 This is a second-view structural schematic diagram of an embodiment of the cover plate control device of this application. The cover plate control device 1 includes a rotating member 14, which is connected to the first end of the cover plate 11 and the observation port 21, so that the cover plate 11 is rotatably positioned at the observation port 21.

[0042] In one embodiment, the rotating member 14 can be a pin, bearing, or other structure. This application does not limit the specific structure of the rotating member 14.

[0043] Then, the pull rope 123 is connected to the second end of the cover plate 11. The pull rope 123 can pull the cover plate 11 to rotate around the connection point between the cover plate 11 and the rotating part 14, switching the cover plate 11 to the first state. When the user needs to observe the inside of the kiln, the pull rope 123 can pull the cover plate 11 to... Figure 2 The viewing angle shown is rotated clockwise to switch to the first state, so as to open the observation port 21. After the user finishes observing, the lifting mechanism 12 can not apply force to the cover plate 11. The cover plate 11 can switch from the first state to the second state under its own weight.

[0044] The cover plate 11 can be rotated relative to the observation port 21 by means of the rotating component 14, which simplifies the setting structure of the cover plate control device 1, reduces the installation difficulty for users, and reduces the manufacturing cost of the cover plate control device 1.

[0045] Furthermore, the distance between the connection point of the pull rope 123 and the cover plate 11 and the connection point of the cover plate 11 and the rotating component 14 is greater than the distance between the center of the cover plate 11 and the connection point of the cover plate 11 and the rotating component 14. Thus, with the connection point of the cover plate 11 and the rotating component 14 as the fulcrum, the distance between the center of the cover plate 11 and the connection point of the cover plate 11 and the rotating component 14 as the resistance arm, and the distance between the connection point of the pull rope 123 and the cover plate 11 and the connection point of the cover plate 11 and the rotating component 14 as the power arm, the power arm is greater than the resistance arm, forming a force-saving lever, reducing the force required for the lifting mechanism 12 to pull the cover plate 11 to rotate, and improving the operating efficiency of the lifting mechanism 12.

[0046] See Figure 2 Optionally, a pull ring 111 is provided on the side of the cover plate 11 away from the observation port 21, and one end of the pull rope 123 is connected to the pull ring 111 so that the pull rope 123 pulls the pull ring 111 to switch the cover plate 11 to the first state.

[0047] In one embodiment, the pull ring 111 can be a triangular lifting lug. The connection between the pull rope 123 and the cover plate 11 is actually the connection between the pull rope 123 and the pull ring 111. The pull rope 123 and the pull ring 111 can rotate relative to each other, preventing wear and tear at the connection point due to the rotation of the cover plate 11 when the user pulls the cover plate 11 using the pull rope 123, thus ensuring the stability of the pull rope 123. By providing a pull ring 111 connected to the pull rope 123 on the cover plate 11, the stability and safety of the cover plate control device 1 are improved.

[0048] Alternatively, please continue reading Figure 2 and Figure 3 , Figure 3 This is a schematic diagram of an embodiment of the fastening mechanism of this application. The fastening mechanism 13 includes a second support frame 131, a pressure rod 132, and a support rod 133.

[0049] The second support frame 131 is mounted on the side wall 2 of the kiln where the observation port 21 is located. A pressure rod 132 is rotatably connected to the second support frame 131. Vertically, the second support frame 131 and the pressure rod 132 are located below the observation port 21. One end of a support rod 133 is rotatably connected to the second support frame 131, and the pressure rod 132 abuts against the support rod 133 to fix the cover plate 11 in its second state. The pressure rod 132 and the support rod 133 can be assembled to the second support frame 131 using rivets, allowing the pressure rod 132 and the support rod 133 to be rotatably connected to the second support frame 131 respectively.

[0050] Furthermore, a limiting member 134 is provided on the pressure rod 132. One end of the limiting member 134 is disposed on the pressure rod 132, and the other end of the limiting member 134 abuts against the support rod 133 to maintain the vertical state of the support rod 133, such as... Figure 1 or Figure 2 As shown, the limiting member 134 abuts against the support rod 133, and then the end of the vertical support rod 133 away from the second support frame 131 abuts against the cover plate 11 to fix the cover plate 11 in the second state.

[0051] Optionally, the other end of the support rod 133 is provided with an abutment 1331, which passes through the support rod 133. The extension direction of the abutment 1331 is perpendicular to the extension direction of the support rod 133, and one end of the abutment 1331 abuts against the cover plate 11.

[0052] If the support rod 133 directly abuts against the surface of the cover plate 11, since one end of the support rod 133 is located below the observation port 21, it cannot be perpendicular to the surface of the cover plate 11. As mentioned earlier, when the extension direction of one end of the fastening mechanism 13 is perpendicular to the surface of the cover plate 11, the fastening mechanism 13 can provide a greater force to the cover plate 11. Therefore, if the support rod 133 is used to abut against the cover plate 11, it is impossible to fix the cover plate 11. In this embodiment, it is proposed to provide an abutment member 1331 at one end of the support rod 133. The extension direction of the abutment member 1331 is perpendicular to the extension direction of the support rod 133, that is, the abutment member 1331 can be perpendicular to the surface of the cover plate 11.

[0053] The abutment 1331 can be a bolt. When the support rod 133 is in a vertical position, since the extension direction of the abutment 1331 is perpendicular to the extension direction of the support rod 133, the abutment 1331 will abut against the cover plate 11. The extension direction of the abutment 1331 is perpendicular to the surface of the cover plate 11, so as to provide a force to the cover plate 11 close to the observation port 21, and prevent the cover plate 11 from being pushed away from the observation port 21 by the high-temperature expanding gas inside the kiln.

[0054] Optionally, the other end of the support rod 133 may also be provided with two adjusting members 1332. The two adjusting members 1332 are provided on the abutment member 1331 and are provided at both ends of the abutment member 1331 passing through the support rod 133, so as to adjust the distance between the end of the abutment member 1331 that abuts against the cover plate 11 and the support rod 133.

[0055] If the user notices that the cover plate 11 is not tightly covering the observation port 21, the user can adjust the two adjusting parts 1332 to increase the distance between the end of the abutment 1331 that abuts the cover plate 11 and the support rod 133. Then, the cover plate 11 will move closer to the observation port 21 under the action of the abutment 1331, so that the cover plate 11 is tightly covering the observation port 21.

[0056] If the user notices that the extension direction of the abutment 1331 is not perpendicular to the surface of the cover plate 11, that is, the distance between the end of the abutment 1331 that abuts the cover plate 11 and the support rod 133, the user can adjust the two adjusting parts 1332 to reduce the distance between the end of the abutment 1331 that abuts the cover plate 11 and the support rod 133. Then the support rod 133 can drive the abutment 1331 to move closer to the cover plate 11, so that the extension direction of the abutment 1331 is perpendicular to the surface of the cover plate 11, thereby improving the fixing efficiency of the fastening mechanism 13 on the cover plate 11. By setting the distance between the end of the abutment 1331 that abuts the cover plate 11 and the support rod 133, the flexibility of the fastening mechanism 13 is improved, and the user's experience with the cover plate control device 1 is enhanced.

[0057] Optionally, the fastening mechanism 13 further includes a gasket 135, which is disposed between the adjusting member 1332 and the support rod 133 to reduce the friction between the support rod 133 and the adjusting member 1332, and to fix the abutment member 1331, so as to prevent the abutment member 1331 from shaking and reducing the fastening efficiency of the fastening mechanism 13 on the cover plate 11.

[0058] In this embodiment, the fastening mechanism 13 can be a CH-101-H type vertical quick clamp, which has a simple structure and low cost. In other embodiments, the fastening mechanism 13 may also adopt other types of structures, and this application does not limit this.

[0059] The following is a brief description of the operation process of cover plate control device 1:

[0060] When the user needs to observe the inside of the kiln, the user can first press down the pressure rod 132, which will drive the limiting part 134 to... Figure 2 The angle shown rotates counterclockwise. When the support rod 133 loses the contact of the limiting member 134, it cannot maintain a vertical position due to the different gravitational forces acting on its two ends at the contact member 1331. It also rotates counterclockwise, causing the contact member 1331 to move away from the cover plate 11. Then, the user pulls the end of the pull rope 123 away from the cover plate 11. The synchronous pulley 122 transmits the pull rope 123, and the cover plate 11 rotates clockwise under the action of the pull rope, switching from the second state to the first state, opening the observation port 21. The user can then observe the interior of the kiln through the observation port 21.

[0061] After the user has finished observing, the user can release the pull rope 123, and the cover plate 11 will rotate counterclockwise under its own weight, switching from the first state to the second state, and will be placed back on the observation port 21. Then the user can rotate the pressure rod 132 clockwise, and the pressure rod 132 will drive the limiting member 134 to move. The limiting member 134 will rotate until it abuts against the support rod 133, and drive the support rod 133, pressure rod 132 and limiting member 134 to rotate synchronously until the abutting member 1331 on the support rod 133 abuts against the cover plate 11. At this time, since one end of the limiting member 134 abuts against the support rod 133, the support rod 133 can no longer rotate. A stable triangle is formed between the pressure rod 132, the support rod 133 and the limiting member 134. The pressure rod 132 cannot continue to rotate due to the restriction of the limiting member 134. At this time, the pressure rod 132 and the support rod 133 return to their original state, and the fastening mechanism 13 fixes the cover plate 11.

[0062] The fastening mechanism 13 may further include a limiting structure (not shown) to restrict the pressure rod 132 as it returns to its original position, preventing excessive force from the gas in the kiln on the cover plate 11. This would cause the cover plate 11 to push the abutment 1331 away from the cover plate 11, and then, under the action of the abutment 1331, the support rod 133 and the pressure rod 132 to rotate counterclockwise, reducing the fastening efficiency of the fastening mechanism 13. When the user needs to press down on the pressure rod 132, the limiting structure can release the restriction on the pressure rod 132, allowing the user to easily press down on it.

[0063] In one embodiment, one end of the limiting member 134 may be rotatably connected to the pressure rod 132, and the other end may also be rotatably connected to the support rod 133. Thus, as the pressure rod 132 rotates counterclockwise to loosen the cover plate 11, the support rod 133 will rotate counterclockwise synchronously with the pressure rod 132 under the action of the limiting member 134, causing the abutment member 1331 to move away from the cover plate 11 and loosen the cover plate 11, allowing the user to open the cover plate 11 to observe the inside of the kiln. After the user has finished observing, the cover plate 11 is repositioned at the observation port 21, and the pressure rod 132 rotates clockwise, causing the limiting member 134 to rotate. At the same time, the limiting member 134 will also cause the support rod 133 to rotate until the abutment member 1331 on the support rod 133 abuts against the surface of the cover plate 11. The fastening mechanism 13 fixes the cover plate 11 in the second state, improving safety and the practicality of the cover plate control device 1.

[0064] In summary, the cover plate control device 1 provided in this application covers the observation port 21 of the kiln with a cover plate 11. The lifting mechanism 12 pulls the cover plate 11 to switch to the first state, and the fastening mechanism 13 fixes the cover plate 11 in the second state. This allows the user to open the observation port 21 by pulling the cover plate through the lifting mechanism 12 when the user needs to observe the inside of the kiln, reducing the difficulty of opening the observation port 21, improving safety, and enhancing the user's experience with the cover plate control device 1. When the user does not need to observe the inside of the kiln, the fastening mechanism 13 can fix the cover plate 11 to the observation port 21 to seal the inside of the kiln and ensure the melting efficiency of the kiln.

[0065] This application also provides a glass furnace (not shown in the figure), which includes a cover plate control device 1.
