Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a fully liquid-contact floating roof connecting beam, a floating roof assembly, and a floating roof. Background Technology

[0002] Volatile organic compounds (VOCs) are substances other than particulate matter, SO2, and NO. x Another type of air pollutant is toxic to human skin, eyes, nerves, and internal organs, and can also cause secondary pollution under sunlight. In recent years, reducing VOC emissions from storage tanks storing volatile liquids has become a key focus. Traditional floating roofs have relatively high VOC emissions due to the presence of oil and gas evaporation space, failing to meet the limits set by standards and regulations. In contrast, fully wetted floating roofs consist of floating elements continuously covering the liquid surface, eliminating the oil and gas space between the floating roof and the liquid surface. They offer advantages such as multiple buoyancy units, stable operation, and simple construction, and have become the current trend in technological development.

[0003] However, most fully wetted floating roofs currently available are metal-based. Due to limitations in their structure and materials, they present several uncertain safety hazards. For example: 1) They are constructed from assembled floating roof units. Due to constraints on manhole dimensions, the length and width of each unit differ significantly (generally, the length is greater than 3 meters and the width is less than 0.6 meters). This results in a large difference in the flexural modulus of the assembled units in the length and width directions. During subsequent use, the vertical movement of the floating roof within the tank makes the direction with the smaller flexural modulus more prone to bending or twisting. If this deformation is not controlled or corrected in time, it may gradually intensify and eventually lead to serious problems such as floating roof breakage or jamming. 2) Some fully wetted floating roofs use connecting beams to connect the floating roof units. However, due to transportation size limitations, existing floating roofs often use short beams spliced ​​together to form a longer beam. The short beams have bending points, and over long-term service, the beam joints may break. These problems not only affect the normal use of the floating roof but may also damage the equipment or systems it supports, and even cause safety accidents. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model discloses a fully liquid-contact floating roof connecting beam, a floating roof assembly, and a floating roof. The connecting beam has no bending points and exhibits excellent bending resistance. The floating roof assembly including the connecting beam and the fully liquid-contact floating roof have a robust and reliable structure with strong safety.

[0005] To achieve the above technical objectives, on the one hand, this utility model proposes a fully liquid-contact floating roof connecting beam, including several segmented beams and bearing inserts; wherein, the segmented beam is a hollow structure containing at least two opposing surfaces, and the two ends of the bearing insert are respectively nested and inserted into the hollow cavities of two adjacent segmented beams.

[0006] The above technical solution requires no welding. By nesting and inserting the bearing inserts into the adjacent segmented beams, the splicing of the fully liquid-contact floating roof connecting beams is achieved, making the operation very simple. In addition, the assembled connecting beams have no bending points. The bearing inserts in the adjacent segmented beams enhance the flexural modulus in the extension direction of the connecting beams, greatly improving the flexural performance of the composite beams. This is beneficial for balancing the uniformity of forces in all directions during the use of the floating roof, especially during long-term vertical operation, thereby improving the structural stability and service life of the fully liquid-contact floating roof.

[0007] In a further example of this utility model, the connection method between segmented beams, the structure of segmented beams, length and other technical features have been optimized. The embodiments of this utility model show the specific optimizations and technical effects.

[0008] On the other hand, this utility model proposes a fully liquid-contact floating roof assembly, which includes the aforementioned fully liquid-contact floating roof connecting beam and several floating roof units; wherein, the end face of the floating roof unit is connected to the opposite face of the connecting beam, and the end face of the floating roof unit covers the joint of two adjacent segmented beams.

[0009] In the above technical solution, the end face of the floating roof unit just covers the joint of two adjacent segment beams on the fully liquid-contact floating roof connecting beam. The floating roof units are reliably connected together by the fully liquid-contact floating roof connecting beam, which not only enhances the bending resistance at the joint of two adjacent segment beams, but also further eliminates the defects of the bending point of the existing fully liquid-contact floating roof. In addition, the method of seamlessly splicing the fully liquid-contact floating roof connecting beam into the floating roof unit is simple to operate, and the resulting fully liquid-contact floating roof component product is aesthetically pleasing.

[0010] On the other hand, this utility model proposes a floating roof that includes the above-mentioned fully liquid-contact floating roof connecting beam or the above-mentioned fully liquid-contact floating roof assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the connecting beam of the fully liquid-contact floating roof of this utility model has no bending points, and the bearing inserts in the adjacent segment beams enhance the bending modulus in the extension direction of the connecting beam, which greatly improves the bending performance of the connecting beam; the floating roof assembly including the fully liquid-contact floating roof connecting beam and the floating roof itself, during use, especially during long-term use, ensure uniform stress in all directions, avoid bending deformation, and improve the structural stability and service life of the fully liquid-contact floating roof.
