Description

Technical Field

[0001] This utility model relates to the field of floating roof technology, and in particular to a double-disc floating roof made of all-stainless steel welded metal tubes. Background Technology

[0002] A floating roof is a floating cover that floats on the surface of the oil in an oil storage tank and rises and falls with the oil. It can effectively reduce the evaporation loss of the oil medium in the storage tank, prevent air pollution, and reduce the evaporation loss of the oil medium.

[0003] In the existing technology, the traditional steel floating roof is made of carbon steel, which requires on-site welding. The construction work is extensive and the construction risk is high. The floating roof has poor resistance to oil corrosion and requires periodic anti-corrosion treatment. The safety of the floating roof structure needs to be improved after long-term use. In addition, the floating roof has poor anti-sinking ability when liquid is introduced, and the maintenance risk is high. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a double-disc floating roof made of all stainless steel welded metal tubes to solve the problem of poor anti-sinking performance.

[0005] To achieve the above objectives, this utility model provides a double-disc floating roof made entirely of stainless steel welded metal tubular material, comprising multiple interconnected box-shaped components. Each box-shaped component includes a box with an open upper end, a lower panel, and vertically arranged side panels on all four sides of the lower panel. The box is filled with multiple vertically arranged support tubes. An upper panel is provided at the upper end of the box. The lower ends of the support tubes are sealed and welded to the upper surface of the lower panel, and the upper ends of the support tubes are sealed and welded to the lower ends of the upper panel, so that the space inside the support tubes is an independent and sealed space. The box, the upper panel, and the support tubes are all made of stainless steel.

[0006] Optionally, a bottom fixing member is welded to the lower end face of the box body, and one side of the bottom fixing member is attached to the bottom of the lower panel.

[0007] Optionally, the lower panel is integrally formed with the side panels on its four sides.

[0008] Optionally, two adjacent housing components are connected by fasteners, and a sealing element is provided in the gap between the two adjacent housing components for sealing.

[0009] Optionally, the sealing element includes an abutment portion and a deformation portion. The deformation portion consists of multiple prismatic blocks arranged vertically, with the multiple prismatic blocks connected end to end in sequence. An abutment portion is vertically arranged at the upper end of the deformation portion, and the abutment portion is an abutment plate.

[0010] Optionally, the surface of the floating roof, the bottom surface of the upper panel, and the top surface of the lower panel are all planar.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a double-disc floating roof made entirely of stainless steel welded metal tubes. The floating roof is made entirely of stainless steel, with stainless steel support tubes serving as strength fillers. The stainless steel support tubes are completely welded to the upper and lower panels to form an independent and sealed unit. Even if the tank components experience extreme liquid ingress, the internal area of ​​the tank components remains independent, and the internal stainless steel support tubes have little impact on liquid flow. Liquid drainage is simple and quick, and the tank components still have basic buoyancy, allowing the floating roof to float on the liquid surface, thus improving the anti-sinking performance of the floating roof.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] like Figures 1 to 5 As shown, a double-disc floating roof made entirely of stainless steel welded metal tubular material includes multiple interconnected box components 1. Each box component 1 includes a box 4 with an open upper end. The box 4 includes a lower panel 5 and side panels 6 vertically arranged on all four sides of the lower panel 5. The box 4 is filled with multiple vertically arranged support tubes 7. The upper end of the box 4 is provided with an upper panel 3. The lower end of the support tube 7 is sealed and welded to the upper surface of the lower panel 5, and the upper end of the support tube 7 is sealed and welded to the lower end of the upper panel 3, so that the space inside the support tube 7 is an independent and sealed space. The box 4, the upper panel 3, and the support tubes 7 are all made of stainless steel. Stainless steel has a higher melting point and better fire resistance than aluminum. At high temperatures, the stainless steel support tubes 7 do not soften, deform, or fail.

[0022] The entire floating roof is made of stainless steel to avoid corrosion problems. The internal filling of the tank component 1 abandons the traditional aluminum honeycomb core and uses stainless steel support tubes 7 as the strength filling material. The support tubes 7 are welded to the upper panel 3 and the lower panel 5 through welding process to prevent the internal adhesive of the tank component 1 from aging or falling off due to oil corrosion, thereby improving the strength of the tank component 1 and ensuring the safe operation of the floating roof. In addition, it effectively avoids the honeycomb structure from dividing the internal space of the tank component 1 and affecting the drainage effect of the tank component 1.

[0023] Stainless steel support pipe 7 is used as the internal strength support component of the box component 1. The stainless steel support pipe 7 is integrally formed by stamping and welding. The end of the support pipe 7 is reserved with a welding contact surface so that it can be welded and fixed to the upper panel 3 and the lower panel 5 of the box component 1. After welding, the stainless steel support pipe 7 is completely welded to the upper panel 3 and the lower panel 5 to form an independent sealed unit. Even if the box component 1 is subjected to extreme liquid ingress, the internal area of ​​the box component 1 is independent, the internal stainless steel support pipe 7 has little impact on the liquid flow, the liquid drainage is simple and quick, the box component 1 still has basic buoyancy, and the floating top can still float on the liquid surface, thus improving the anti-sinking performance of the floating top.

[0024] The compressive strength, tensile strength, and bending deformation resistance of floating roofs are higher than those of traditional floating roofs, resulting in higher operational safety.

[0025] Bottom fixing parts are welded to the lower end face of the box body 4. The bottom fixing parts are angle steels and are welded to the lower panel 5. One side of the bottom fixing parts is attached to the bottom of the lower panel 5 to improve the overall connection strength of the floating roof.

[0026] The lower panel 5 and its four side panels 6 are integrally formed by bending.

[0027] Multiple enclosure components 1 include multiple standard module enclosures and multiple edge non-standard module enclosures. The floating roof edge structure is optimized by connecting enclosure components 1 of different specifications, which further reduces the connection length of the edge non-standard module enclosures and increases the proportion of standard modules in the floating roof.

[0028] Two adjacent housing components 1 are connected by fasteners to secure them together as a whole. The fasteners can be bolts and nuts. A sealing element 2 is provided in the gap between two adjacent housing components 1 to seal the gap and prevent oil vapor from spreading to the top of the floating roof.

[0029] To improve the sealing effect of the gap between the floating roof panels, the sealing element 2 includes an abutment part 8 and a deformation part 9. The deformation part 9 consists of multiple prismatic blocks arranged vertically, with the multiple prismatic blocks connected end to end in sequence. The abutment part 8 is vertically arranged at the upper end of the deformation part 9, and the abutment part 8 is an abutment plate.

[0030] During the bolt tightening process of two adjacent box components 1, the deformation part 9 has a prismatic structure and is elastic. The deformation part 9 is deformed by the side wall of the gap between the two adjacent box components 1. The prismatic structure deforms due to the force, fills the gap area, and isolates the oil and gas escape channel, so that the deformation part 9 and the side wall of the two adjacent box components form a seal. The abutment plate is located at the end of the gap between the two adjacent box components 1. The setting of the abutment plate further prevents oil and gas from entering the gap and prevents oil and gas from spreading to the top of the floating roof through the gap.

[0031] The surface of the floating roof, the bottom surface of the upper panel 3, and the top surface of the lower panel 5 are all flat. The surface of the floating roof is flat and without bumps, which makes the overall structure of the box component 1 more solid, stable and leak-free, and makes the overall buoyancy more uniform, which can effectively avoid the floating roof deflection and jamming.

[0032] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
