Description

Technical Field

[0002] In the field of liquid storage, as a core device to ensure storage safety and efficiency, the fully liquid-contact internal floating roof has been committed to reducing liquid evaporation and enhancing storage stability for a long time. However, with the rapid development of industrial technology and the continuous improvement of environmental protection standards, the design limitations of traditional fully liquid-contact internal floating roofs have gradually emerged. Specifically, for existing fully liquid-contact internal floating roofs, due to the non-adjustability of their structures, they cannot be adjusted after installation, which easily affects the sealing effect. After long-term use, there may be a situation where local sealing is insufficient, resulting in leakage. At the same time, due to the relatively fixed structure of existing internal floating roofs, they are unable to cope when faced with diverse storage tank conditions. Even if there are slight deviations in the size or shape of the storage tank, it may cause the floating roof to not match precisely, thereby increasing the installation difficulty and even affecting the normal operation and maintenance of the floating roof.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Enhanced sealing performance: By providing a sealing layer on the elastic sealing plate that closely cooperates with the inner wall of the storage tank, and installing a sealing ring on the side of the upper sealing pressing plate that cooperates with the inner wall of the storage tank, a double-layer sealing structure is achieved. This design significantly improves the sealing performance between the internal floating roof and the storage tank, effectively preventing the volatilization of oil and gas and the intrusion of external impurities, not only ensuring the quality of the stored medium, but also enhancing the safety performance of the storage tank and reducing the risk of environmental pollution;

[0013] 2. Flexible adjustment and adaptability: By screwing the adjusting bolts on the upper sealing pressing plate, combined with the openings on the elastic sealing plate and the threaded holes on the internal floating roof body, flexible adjustment of the sealing pressing force of the elastic sealing plate is achieved.

[0014] 3. Optimized Structural Design and Stability: The support plate sleeved on the inner floating roof body provides stable support for the entire structure. The installation of the support spring endows the elastic sealing plate with certain elastic deformation ability, enabling it to better adapt to the minor deformation or unevenness of the inner wall of the storage tank, thus avoiding wear or leakage problems caused by hard contact. In addition, this structural design also enhances the overall stability of the inner floating roof, extends its service life, and reduces maintenance costs. Brief Description of the Drawings

[0016] Figure 2 is a structural schematic diagram of the inner floating roof body of the present utility model. Detailed Embodiment

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Refer to Figure 1-2 , an improved fully liquid-contact inner floating roof, including an inner floating roof body 2 for serving as the main support. Specifically, the inner floating roof body 2 is a honeycomb structure formed by welding a number of support skeletons. This structure not only enhances the overall strength and stability of the inner floating roof but also greatly reduces its weight, enabling the floating roof to float more flexibly in the liquid, while reducing the demand for buoyancy. In actual application, the inner floating roof body 2 is usually made of corrosion-resistant, high-strength lightweight materials such as stainless steel or aluminum alloy to meet the storage requirements of various chemicals;

[0019] A support plate 3 is sleeved on the inner floating disc body 2. An elastic sealing plate 4 is installed on the top of the inner floating disc body 2 through a support spring 5. The four peripheral edges of the elastic sealing plate 4 are bent inward and fixedly connected to the support plate 3. A sealing layer for cooperating with the inner wall of the storage tank 1 is provided on the elastic sealing plate 4. The elastic sealing plate 4 has a certain elasticity, which is convenient for closely adhering to the inner wall of the storage tank 1 to ensure the sealing performance. Preferably, the elastic sealing plate 4 is made of fluororubber or silicone rubber to ensure that the sealing plate can still maintain good sealing performance in a harsh storage environment. The sealing layer is used to further enhance the sealing performance between the elastic sealing plate 4 and the inner wall of the storage tank 1. Preferably, the sealing layer is composed of several layers of sealing films 10 sleeved on the elastic sealing plate 4. The sealing layer composed of multiple layers of sealing films 10 further improves the sealing effect. Even if a certain layer of the sealing film 10 is damaged, other layers can still provide effective sealing protection. The support plate 3 is used to support and stabilize the elastic sealing plate 4 to ensure that it will not deform or shift during the floating process. It can be designed as a flat plate structure with reinforcing ribs to enhance its load-bearing capacity and stability. Preferably, the support plate 3 is sleeved in the middle of the inner floating disc body 2.

[0020] In order to adjust the elastic sealing plate 4, an upper sealing pressing plate 6 is further installed above the elastic sealing plate 4. The upper sealing pressing plate 6 is bolted to the inner floating disc body 2. An adjusting bolt 8 is screwed on the upper sealing pressing plate 6. The support spring 5 not only supports the elastic sealing plate 4 but also allows it to float within a certain range to adapt to the change of the liquid level in the storage tank 1. The upper sealing pressing plate 6 is connected to the inner floating disc body 2 by bolts, firmly pressing the elastic sealing plate 4 on the support plate 3, and at the same time closely fitting the inner wall of the storage tank 1 at its side to form a second sealing barrier. Preferably, a sealing ring 7 for cooperating with the inner wall of the storage tank 1 is further sleeved on the side of the upper sealing pressing plate 6. The setting of the adjusting bolt 8 not only realizes the installation of the upper sealing pressing plate 6 but also facilitates fine-tuning the gap between the elastic sealing plate 4 and the inner wall of the storage tank 1 to ensure the best sealing effect at different liquid levels.

[0021] Preferably, 6, 8 or 9 support springs 5 are provided. 6, 8 or 9 support springs 5 are evenly distributed on the top of the inner floating disc body 2. 6, 8 or 9 adjusting bolts 8 are provided. 6, 8 or 9 adjusting bolts 8 are evenly distributed on the upper sealing pressing plate 6, which not only ensures the reliability of the installation of the upper sealing pressing plate 6 but also ensures that the elastic sealing plate 4 can be evenly stressed when subjected to liquid pressure or temperature changes and maintain a stable sealing state.

[0022] To ensure the sealing performance at the installation location of the adjusting bolt 8, an opening that mates with the adjusting bolt 8 is provided on the elastic sealing plate 4, a threaded hole that mates with the adjusting bolt 8 is provided on the inner floating roof body 2, and a sealing gasket 9 that mates with the upper sealing pressing plate 6, the elastic sealing plate 4, and the inner floating roof body 2 is also sleeved on the adjusting bolt 8. The use of the sealing gasket 9 further enhances the sealing effect and prevents liquid or gas from leaking through the bolt hole.

[0023] The usage process of an improved fully liquid-contact inner floating roof provided by the present utility model is as follows:

[0024] First, install the inner floating roof body 2 and its supporting structure (such as the support plate 3, the support spring 5, etc.) inside the storage tank 1 according to the design requirements. After installation, conduct debugging to ensure that all components are in a normal working state, especially that the adjusting bolt 8 and the sealing gasket 9 have been adjusted to the optimal position;

[0025] Next, the elastic sealing plate 4 is installed on the top of the inner floating roof body 2 through the support spring 5 and fixedly connected to the support plate 3. At this time, the multi-layer sealing films 10 and the sealing layer on the elastic sealing plate 4 are in place and are ready to form a tightly fitting sealing state with the inner wall of the storage tank 1;

[0026] Then, when liquid starts to be injected into the storage tank 1, the liquid level gradually rises. Due to the buoyancy effect of the inner floating roof body 2, it starts to float as the liquid level rises;

[0027] Supported by the support spring 5, the elastic sealing plate 4 always maintains close contact with the inner wall of the storage tank 1. As the liquid level rises, the pressure on the elastic sealing plate 4 gradually increases, but the design of its multi-layer sealing films 10 and the sealing layer can effectively resist this pressure and maintain the sealing effect;

[0028] If it is found that the sealing effect is not good (such as there is a leakage phenomenon) during the rising process of the liquid level, the gap between the elastic sealing plate 4 and the inner wall of the storage tank 1 can be finely adjusted by rotating the adjusting bolt 8 on the upper sealing pressing plate 6. This adjustment is usually subtle and aims to ensure that the sealing effect reaches the optimal state;

[0029] At the same time, the design of the inner floating roof also takes into account the possible minor unevenness or deformation of the inner wall of the storage tank 1. By adjusting the tightness of the support spring 5 and the shape of the elastic sealing plate 4 (such as the design that the four peripheral edges are bent inward), these minor changes can be adapted to maintain the sealing effect.
