Description

Technical Field

[0001] This utility model relates to the field of petrochemical storage technology, and in particular to a lightweight internal floating disc. Background Technology

[0002] In industries such as petroleum, chemical, and storage, storage tanks are key equipment for storing liquid raw materials, intermediate products, and finished products. Their safe and efficient operation is of paramount importance. As an important component inside the storage tank, the internal floating roof can effectively reduce the evaporation loss of the stored medium, reduce the risk of environmental pollution, and improve the safety of the storage tank operation.

[0003] When an internal floating roof is needed, a special lifting device is used to smoothly lift the assembled internal floating roof into the storage tank. The position of the internal floating roof is adjusted to ensure that the guide device is aligned with the guide rail on the inner wall of the storage tank. Then, the fit between the sealing device and the inner wall of the storage tank is checked to ensure a tight seal without gaps. After the internal floating roof is installed, liquid is slowly injected into the storage tank. The floating roof is observed to rise and fall horizontally as the liquid level rises, and whether there is any tilting or jamming. After the floating roof rises to the highest liquid level, the storage tank is slowly emptied, and the stability of the floating roof during descent is observed to confirm that the guide device and sealing device are working properly. However, internal floating roofs have many limitations in practical applications. Their sealing structure mostly uses fixed sealing components, which are difficult to adaptively adjust the sealing pressure when the medium fluctuates or the storage tank operating conditions change, resulting in a decrease in sealing effect and prominent medium evaporation problems. This not only wastes resources but may also cause environmental pollution and safety hazards. Therefore, in order to solve this problem, we propose a lightweight internal floating roof. Utility Model Content

[0004] The purpose of this utility model is to provide a lightweight internal floating disc that uses rollers to maintain a tight seal on the sealing ring, effectively preventing the evaporation of the medium, reducing oil loss, reducing environmental pollution, and improving storage safety. It ensures that the upper and lower floating discs maintain a stable connection under conditions such as fluctuations in the stored medium, avoiding loosening or displacement, and achieving the dual advantages of convenient and efficient storage and safe and reliable use.

[0005] To achieve the above objectives, a lightweight internal floating platform is provided, comprising an upper floating platform and a lower floating platform on one side of the upper floating platform. Multiple first fixed plates are fixedly installed on the exterior of both the upper and lower floating platforms, and multiple second fixed plates are fixedly installed on the exterior of both the upper and lower floating platforms. A first transmission plate is movably fitted inside each of the first fixed plates, and a second transmission plate is movably fitted inside each of the second fixed plates. A limit shaft is movably fitted inside each of the first transmission plates, and a first spring is fixedly installed on one side of each limit shaft. Rollers are movably fitted at one end of each of the first and second transmission plates. The upper floating plate has a sliding groove inside, and a sliding plate is movably fitted inside the sliding groove. A connecting plate is movably fitted at one end of the sliding plate. A third fixing plate is fixedly installed on one side of the lower floating plate, and two positioning plates are fixedly installed on one side of the lower floating plate. The upper floating plate has two limiting grooves inside. Two sleeves are fixedly installed above the upper floating plate. A fixing shaft is movably fitted inside the sleeve. A limiting plate is fixedly installed outside the fixing shaft. A second spring is fixedly installed inside the fixing shaft. Sealing rings are fixedly connected to the outside of both the upper and lower floating plates.

[0006] According to the aforementioned lightweight inner floating disk, one end of the limiting shaft is movably fitted inside the second transmission plate, and one end of the first spring is fixedly connected to the outside of the upper floating disk and the lower floating disk.

[0007] According to the aforementioned lightweight internal floating disc, the outer surface of the roller is in close contact with the inner wall of the sealing ring.

[0008] According to the aforementioned lightweight internal floating disk, the connecting plate is movably fitted inside the third fixed plate, and both the connecting plate and the third fixed plate are inside the sliding groove.

[0009] According to the aforementioned lightweight inner floating disk, the positioning plate can be fitted inside the limiting groove of the upper floating disk, and the fixing shaft can extend into the interior of the positioning plate.

[0010] According to the aforementioned lightweight internal floating disk, one end of the second spring is fixedly connected to the limiting plate, and the second spring is disposed outside the fixed shaft.

[0011] According to the aforementioned lightweight internal floating disk, the first transmission plate and the second transmission plate are staggered, and the first transmission plate and the second transmission plate can form a foldable X-shaped structure through a limiting shaft.

[0012] According to the aforementioned lightweight internal floating disk, the two ends of the sliding groove are provided with limiting baffles, which are used to limit the sliding stroke of the sliding plate.

[0013] Beneficial effects:

[0014] 1. The sealing rings fixedly connected to the upper and lower floating roofs, together with the coordinated action of the first transmission plate, the second transmission plate and the rollers, ensure that the outer surface of the rollers is in close contact with the inner wall of the sealing rings. When the inner floating roof is affected by external forces such as media fluctuations, the first and second transmission plates can flexibly adjust their positions. The rollers always maintain a tight squeeze on the sealing rings, effectively preventing media evaporation, reducing oil loss, reducing environmental pollution, and improving storage safety.

[0015] 2. Through the ingenious cooperation of the sliding groove, sliding plate, connecting plate and third fixed plate, the upper and lower floating plates can be easily folded and stored, effectively reducing the space occupied and facilitating handling and storage. During use, the positioning plate, sleeve, fixed shaft and second spring form a fixed connection structure. After the positioning plate is embedded in the upper floating plate limiting groove, the fixed shaft is quickly inserted into the positioning plate under the elastic force of the second spring, forming a firm locking structure. This ensures that the upper and lower floating plates maintain a stable connection under conditions such as fluctuations in the storage medium, avoiding loosening or displacement, and achieving the dual advantages of convenient and efficient storage and safe and reliable use.

A lower floating roof 2 is provided on one side of the upper floating roof 1, which effectively reduces the evaporation loss of the stored medium. Multiple first fixing plates 3 are fixedly installed on the exterior of both the upper and lower floating roofs 1 and 2, facilitating the movement of a first transmission plate 5. Multiple second fixing plates 4 are also fixedly installed on the exterior of both the upper and lower floating roofs 1 and 2, facilitating the movement of a second transmission plate 6. The first transmission plate 5 is movably fitted inside the first fixing plate 3. The transmission plate 5 facilitates the movement of the roller 9. A second transmission plate 6 is movably mounted inside the second fixed plate 4, allowing the roller 9 to move. A limit shaft 7 is movably mounted inside the first transmission plate 5, facilitating the movement of both the first transmission plate 5 and the second transmission plate 6. A first spring 8 is fixedly mounted on one side of the limit shaft 7. One end of the first spring 8 is fixedly connected to the outside of the upper floating plate 1 and the lower floating plate 2, and the other end is fixedly connected to the limit shaft 7. The compression or release of the first spring 8 adjusts the position of the roller 9, causing the roller 9 to continuously compress the sealing ring 19. The first transmission plate 5 and the second transmission plate 6... Rollers 9 are movably fitted at one end of each movable plate 6, continuously applying pressure to the sealing ring 19 via the rollers 9. A sliding groove 10 is provided inside the upper floating plate 1, allowing the sliding plate 11 to slide. The sliding plate 11 is movably fitted inside the sliding groove 10, driving the connecting plate 12 to move. The connecting plate 12 is movably fitted at one end of the sliding plate 11, facilitating the folding of the upper floating plate 1 and the lower floating plate 2. A third fixing plate 13 is fixedly installed on one side of the lower floating plate 2, facilitating its folding. Two positioning plates 14 are fixedly installed on one side of the lower floating plate 2, allowing for the folding of the lower floating plate 2. Position plate 14 facilitates the fixing of the lower floating plate 2. The upper floating plate 1 has two limiting grooves on both sides inside. Two sleeves 15 are fixedly installed on the upper floating plate 1. The sleeves 15 facilitate the movement of the fixed shaft 16. The fixed shaft 16 is movably fitted inside the sleeves 15. The fixed shaft 16 facilitates the disassembly of the upper floating plate 1 and the lower floating plate 2. A limiting plate 17 is fixedly installed on the outside of the fixed shaft 16. The limiting plate 17 can limit the fixed shaft 16. A second spring 18 is fixedly installed inside the fixed shaft 16. The elastic effect of the second spring 18 is used to fix the lower floating plate 2. Sealing rings 19 are fixedly connected to the outside of both the upper floating plate 1 and the lower floating plate 2.

[0029] Specifically: one end of the limiting shaft 7 is movably fitted inside the second transmission plate 6, and one end of the first spring 8 is fixedly connected to the outside of the upper floating plate 1 and the lower floating plate 2. The first spring 8 can drive the roller 9 to move.

[0030] Specifically: the outer surface of the roller 9 is in close contact with the inner wall of the sealing ring 19, and the roller 9 continuously applies pressure to the sealing ring 19 to ensure that the sealing ring 19 always fits tightly against the inner wall of the storage tank.

[0031] Specifically: the connecting plate 12 is movably fitted inside the third fixing plate 13. Both the connecting plate 12 and the third fixing plate 13 can be inside the sliding groove 10. When the connecting plate 12 and the third fixing plate 13 slide inside the sliding groove 10, it is convenient to store the upper floating plate 1 and the lower floating plate 2.

[0032] Specifically: the positioning plate 14 can be fitted into the limiting groove of the upper floating plate 1, and the fixing shaft 16 can extend into the interior of the positioning plate 14. The lower floating plate 2 can be fixed by extending the fixing shaft 16 into the interior of the positioning plate 14.

[0033] Specifically: one end of the second spring 18 is fixedly connected to the limiting plate 17, and the second spring 18 is located outside the fixed shaft 16. The fixed shaft 16 can be moved by the second spring 18.

[0034] Specifically: the first transmission plate 5 and the second transmission plate 6 are staggered, and the first transmission plate 5 and the second transmission plate 6 can form a foldable X-shaped structure through the limiting shaft 7. The staggered arrangement of the first transmission plate 5 and the second transmission plate 6 facilitates the roller 9 to continuously apply pressure to the sealing ring 19.

[0035] Specifically: Limiting baffles are provided at both ends of the sliding groove 10. The limiting baffles of the sliding groove 10 are used to limit the sliding stroke of the sliding plate 11. The limiting baffles of the sliding groove 10 limit the sliding plate 11 to prevent the sliding plate 11 from moving excessively.

[0036] Working principle: When this lightweight internal floating roof is applied to a storage tank, the sealing rings 19 fixedly connected to the upper floating roof 1 and the lower floating roof 2 form the basic sealing structure. When the medium in the storage tank is stable, the first transmission plate 5 and the second transmission plate 6 form a stable X-shaped structure through the limiting shaft 7. The rollers 9 movably fitted at one end of the first transmission plate 5 and the second transmission plate 6 are tightly fitted to the inner wall of the sealing ring 19, maintaining the initial sealing state. Once the medium fluctuates or the internal floating roof is affected by external forces, the upper floating roof 1 and the lower floating roof 2 will have relative displacement. At this time, the sealing ring 19 will be in close contact with the inner wall of the storage tank, causing the sealing ring 19 to squeeze the rollers 9. Then, the rollers 9 will cause the first transmission plate 5 and the second transmission plate 6 to flexibly adjust their positions, causing the limiting shaft 7 to squeeze the first spring 8. When the first spring 8 is compressed, the pressure is released, allowing the first transmission plate 5 and the second transmission plate 6 to flexibly adjust their positions, so that the rollers 9 continuously apply pressure to the sealing ring 19, ensuring that the sealing ring 19 is always tightly fitted to the inner wall of the storage tank, effectively preventing the medium from evaporating.

[0037] During transportation or storage, when the inner floating roof needs to be folded and stored, the third fixing plate 13 on one side of the lower floating roof 2 cooperates with the connecting plate 12 to drive the sliding plate 11 to slide in the sliding groove 10, so that the upper floating roof 1 and the lower floating roof 2 can move relative to each other and gradually fold. When the inner floating roof is installed in the storage tank and put into use, the positioning plate 14 of the lower floating roof 2 is embedded in the limiting groove of the upper floating roof 1 to complete the initial positioning. At the same time, the fixing shaft 16 moves in the sleeve 15, and the second spring 18 pushes the limiting plate 17, so that the fixing shaft 16 quickly extends and inserts into the positioning plate 14 to form a firm locking structure, ensuring that the upper floating roof 1 and the lower floating roof 2 are stably connected.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
