Description

Technical Field

[0001] This utility model relates to the field of disc sealing, specifically a double-sealed disc. Background Technology

[0002] A floating roof is a floating top cover that floats on the surface of the oil in an oil storage tank, rising and falling with the oil. It effectively reduces the evaporation of oil in the tank and minimizes oil loss due to evaporation. To prevent oil from overflowing or evaporating through the gap between the roof and the tank wall, and to further reduce oil loss, a sealing structure is usually installed between the roof and the tank wall.

[0003] A search revealed that application number 202323036569.7 discloses a "high-efficiency sealing disc" comprising a locking block. The inner wall of the bottom of the locking block is threadedly connected to the outer wall of the threaded column. The outer wall of the bottom of the threaded column is threadedly connected to the inner wall of the connecting rod. The bottom of the connecting rod is fixedly connected to the top of the fixing column. Both ends of the fixing column are fixedly connected to the inner wall of the disc body. The outer wall of the fixing column is fixedly connected to the inner wall of the disc body. The outer wall of the disc body is fixedly connected to a sealing ring. The inner wall of the bottom of the disc body is provided with a grid air chamber. The bottom of the disc body is fixedly connected to the top of the column. By pulling the lifting block with a lifting tool, the lifting block can lift the entire disc body, facilitating adjustments to the disc body's tilt position. Connectors inside the floating disc connect the entire disc body into a whole, preventing the disc body from disintegrating or developing gaps at the top of the oil and gas, which would severely reduce the disc body's airtightness.

[0004] However, this solution does not adequately address the issue of adjusting the tilted placement. Using a lifting block for adjustment is not only slow, leading to liquid evaporation, but the lifting block is also prone to loose engagement due to the screw connection, causing the disc to tilt. Furthermore, if only one disc deforms, the sealing effect will be significantly reduced.

[0005] Therefore, a double-sealed disc body is needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a double-sealed disc body to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A double-sealed disc body includes a first disc body, a second disc body, a spring device, and a positioning device.

[0010] Furthermore, the first disc body includes a first sealing strip, a spring device, and an aluminum alloy buckle plate. The first sealing strip is used to seal the liquid inside the tank. The first sealing strip is located on the outer ring of the first disc body and contacts the inner wall of the tank body. The spring device is provided to reduce wear on the first sealing strip. The spring device is installed at the connection between the first sealing strip and the first disc body. The aluminum alloy buckle plate inside the first disc body contacts and seals the liquid surface.

[0011] Furthermore, the second disc includes a second sealing strip, a spring device, a regular hexagonal frame, and reinforcing beams. The second sealing strip is used to seal the mixed gas after the liquid in the tank evaporates. The second sealing strip is located on the outer ring of the second disc and contacts the inner wall of the tank. The spring device is provided to reduce wear on the second sealing strip. The spring device is installed at the connection between the second sealing strip and the second disc. The regular hexagonal frame inside the second disc is provided to improve the structural strength of the second disc. A set of reinforcing beams is provided inside the regular hexagonal frame.

[0012] Furthermore, the spring device includes a mounting plate sliding groove and a spring. The mounting plate is located between the spring and the sealing strip and is used to install the spring and the sealing strip.

[0013] Furthermore, the second disc is equipped with perfluorohexanone fire extinguishing patches.

[0014] Furthermore, the inspection port is sealed to the second disc.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows: The horizontal adjustment of the lifting block can be determined by the positioning device, which reduces the wear of the sealing strip and ensures the sealing effect. Moreover, the double sealing setting ensures the sealing effect in special circumstances. If the sealing of the first disc fails, the second disc can also ensure the sealing effect, reducing the loss caused by liquid evaporation or fire. At the same time, the perfluorohexanone fire extinguishing patch set on the top can discharge the gas at the first time of fire and isolate the internal liquid from the air to achieve rapid treatment.

[0028] A double-sealed disc body, the disc body 13 includes a first disc body 1, a second disc body 2, a lifting column 3, a perfluorohexanone fire extinguishing patch 4, an inspection port 5, a spring device 7, and a positioning device 6. The first disc body 1 is located at the bottom of the disc body 13 and is in contact with the liquid surface. The second disc body 2 is located above the first disc body 1, and the first disc body 1 and the second disc body 2 are connected by the lifting column 3. The lifting column 3 is provided for the vertical movement of the disc body 13. The lifting column 3 is located at the center of the disc body 13, connected to the bottom of the first disc body 1, and the second disc body 2 is installed in the middle. The second disc body 2 is provided with an inspection port 5 for maintenance. The second disc body 2 is provided with a perfluorohexanone fire extinguishing patch 4. The positioning device 6 is provided near the edge of the second disc body 2. The positioning device 6 is in contact with the inner wall of the tank 14 to ensure the horizontality of the disc body 13 when it moves vertically. The disc body 13 is provided with a spring device 7 to reduce wear on the sealing strips of the first disc body 1 and the second disc body 2.

[0029] In the specific implementation process, it should be noted that the positioning device 6 includes a positioning rod 602, a rubber wheel 601, a mounting screw 603, and a rotating shaft 604. The positioning rod 602 is used to ensure that the disc body 13 is horizontal. The positioning rod 602 is fixed on the second disc body 2 by the mounting screw 603. The rubber wheel 601 is provided to avoid damaging the tank body 14 when the disc body 13 moves up and down. The rubber wheel 601 and the positioning rod 602 are rotatably connected by the rotating shaft 604.

[0030] In the specific implementation process, it should be noted that the first disc body 1 includes a first sealing strip 8 and an aluminum alloy buckle plate 101. The first sealing strip 8 is used to seal the liquid inside the tank 14. The first sealing strip 8 is located on the outer ring of the first disc body 1 and contacts the inner wall of the tank 14. The spring device 7 is installed at the connection between the first sealing strip 8 and the first disc body 1. The aluminum alloy buckle plate 101 inside the first disc body 1 is provided to contact and seal the liquid surface, so that the position of the liquid surface can be observed more clearly and intuitively.

[0031] In the specific implementation process, it should be noted that the second disc body 2 includes a second sealing strip 9, a regular hexagonal frame 201, and a reinforcing crossbeam 202. The second disc body 2 is provided with a second sealing strip 9 for sealing the tank 14. The second sealing strip 9 is located on the outer ring of the second disc body 2 and contacts the inner wall of the tank 14. The spring device 7 is installed at the connection between the second sealing strip 9 and the second disc body 2. The second disc body 2 is provided with a regular hexagonal frame 201 to improve the structural strength of the second disc body 2. A set of reinforcing crossbeams 202 is provided inside the regular hexagonal frame 201.

[0032] In the specific implementation process, it should be noted that the spring device 7 includes a mounting plate 10, a sliding groove 11 and a spring 12. One end of the spring 12 is connected to the disc body 13 and the other end is connected to the mounting plate 10. The top and bottom of the spring device 7 are provided with sliding grooves 11, which are used for the sliding of the mounting plate 10 when the disc body 13 moves up and down.

[0033] In the specific implementation process, it should be noted that the inspection port 5 and the second disc 2 are in a sealed state.

[0034] The working principle of this embodiment is as follows: In specific use, the rubber wheel 601 in the positioning device 6 is tightly fitted against the inner wall of the tank 14. This tight fit not only reliably ensures that the disc 13 is always in a precise position, but also, due to the flexibility of the rubber wheel 601 during contact with the inner wall of the tank 14, it can, to some extent, avoid scratching the inner wall of the tank 14. This effective protection measure for the inner wall of the tank 14 can ensure the integrity of the tank 14, thereby effectively ensuring the sealing effect of the entire device, preventing possible leakage and other problems, and effectively improving the safety and reliability of the disc 13.

[0035] Furthermore, the positioning rod 602 is installed on the second disc 13 via a mounting screw 603. This installation structure makes it easy to replace or inspect the positioning rod 602. Operators can easily perform related operations, greatly reducing the difficulty and cost of maintenance and repair, and improving the maintainability and practicality of the entire disc 13.

[0036] In practical use, the mounting plate 10 is positioned between the spring 12 and the sealing strip. On the one hand, it provides a stable mounting base for the spring 12, ensuring that the spring 12 maintains its direction during the extension and contraction process, reducing possible abnormal conditions such as skewing and torsion, and ensuring that the mechanical performance of the spring 12 is fully and stably utilized. On the other hand, the mounting plate 10 fits tightly with the sealing strip. When the disc 13 moves up and down according to the changes in the liquid level in the tank 14 or other working conditions, the mounting plate 10 can slide within the sliding groove 11. This can reduce the problem of reduced sealing performance caused by friction between the sealing strip and the tank 14.

[0037] In practical use, the perfluorohexanone fire extinguishing patch 4 also plays a significant role. Once the perfluorohexanone fire extinguishing patch 4 detects a fire or a fire ignition point, it can directly release the perfluorohexanone extinguishing agent in the patch to form a protective layer that can isolate the air and retard flames, thus preventing fires from causing losses.

[0038] The remaining parts not described in this utility model are existing or known technologies.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
