Description

A fully liquid-contact steel single-disc internal floating roof Technical Field

[0001] This utility model relates to the field of floating roof structure technology, specifically to a fully liquid-contact steel single-disc internal floating roof. Background Technology

[0002] The fully wetted steel single-disc internal floating roof is a floating top cover device for storage tanks, offering advantages such as reduced media evaporation, improved safety, and environmental friendliness. Constructed from a single piece of steel plate, its simple structure eliminates complex splicing or compartmentalized designs. This structure reduces potential leakage points, improves the floating roof's sealing performance, and ensures complete contact between the floating roof and the liquid surface, minimizing the vapor space above the liquid and effectively reducing media evaporation losses.

[0003] The existing fully liquid-contact steel single-disc internal floating roof cannot increase the buoyancy of the steel single-disc internal floating roof, so that it can float stably on the liquid surface in the oil tank in a fully liquid-contact manner for a long time. It is not convenient to improve the sealing between the main body of the internal floating roof and the inner wall of the oil tank, so as to avoid leaving gaps and affecting the use effect. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides a fully liquid-contact steel single-disc internal floating roof. The steel single-disc internal floating roof effectively increases the buoyancy of the steel single-disc internal floating roof, enabling it to float stably on the liquid surface inside the oil tank in a fully liquid-contact manner for a long time. This improves the sealing between the main body of the internal floating roof and the inner wall of the oil tank, avoiding gaps that could affect the performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a fully liquid-contact steel single-disc internal floating disk, including an internal floating disk body, an outer reinforcing ring, an inner reinforcing ring, and an inner floating basin. An inner pre-drilled hole is opened at the inner shaft core of the internal floating disk body, and an inner floating basin is fitted inside the inner pre-drilled hole. An inner reinforcing ring is welded to the top of the internal floating disk body and to the outside of the inner floating basin. An outer reinforcing ring is welded to the periphery of the inner reinforcing ring. Reinforcing plates are welded at equal intervals between the inner and outer reinforcing rings.

[0006] The inner floating disk body has mounting holes at equal intervals around the outer reinforcing ring. A hollow cylinder is fitted and fixed inside the mounting holes. A sealing ring is bonded and fitted to the outer edge of the inner floating disk body.

[0007] By adopting the above technical solution, the steel single-disc internal floating roof effectively increases the buoyancy of the steel single-disc internal floating roof, enabling it to float stably on the liquid surface inside the oil tank in a fully liquid-contact manner for a long time. This improves the sealing between the main body of the internal floating roof and the inner wall of the oil tank, preventing gaps from being left and affecting the performance.

[0008] Specifically, the top of the inner floating basin is connected to a connecting pipe, and the top of the connecting pipe is fitted with a sealing cap.

[0009] By adopting the above technical solution, the sealing cap seals the connecting pipe, and removing the sealing cap makes it easy to insert the liquid extraction pipe into the lower end of the oil tank from the connecting pipe, which facilitates material extraction.

[0010] Specifically, an arc-shaped shaping block is welded to the top of the inner floating disc body and between the hollow cylinders, and a connecting rib is welded between the arc-shaped shaping block and the outer reinforcing ring.

[0011] Specifically, the sealing ring is made of PU material, and the inner floating disk body is made of stainless steel material.

[0012] By adopting the above technical solution, the sealing ring is specifically made of PU material, which has excellent wear resistance and repeated flexural performance, good tear resistance and elasticity, and excellent resistance to oil, acid, alkali and low temperature. The stainless steel material has high strength, is not easy to rust and is durable.

[0013] Specifically, the reinforcing plates are provided in multiple sets and arranged radially.

[0014] The beneficial effects of this utility model are:

[0015] (1) The fully liquid-contact steel single-disc internal floating disk described in this utility model effectively increases the buoyancy of the steel single-disc internal floating disk through the inner floating basin and the hollow cylinder set on the outer side, so that it floats on the liquid surface in the oil tank in a long-term and stable manner in a fully liquid-contact form, preventing the oil from evaporating. The inner reinforcing ring, outer reinforcing ring and reinforcing plate effectively improve the overall strength and rigidity of the floating disk, making it less prone to deformation and durable.

[0016] (2) The fully liquid-contact steel single-disc internal floating disk of this utility model uses a sealing ring to improve the sealing between the main body of the internal floating disk and the inner wall of the oil tank, avoiding gaps that would affect the performance. The sealing ring is made of PU material, which has excellent wear resistance and repeated bending performance, good tear resistance and elasticity, and excellent resistance to oil, acid, alkali and low temperature. The arc-shaped shaping block and connecting ribs further improve the strength and deformation resistance of the outer edge of the main body of the internal floating disk. Attached Figure Description

The stainless steel material has high strength, is not easy to rust and is durable.

[0032] As exemplarily shown in FIG1, the present invention also includes multiple sets of the reinforcing plate 3 arranged radially.

[0033] When in use, connecting the inner reinforcing ring 2 and the outer reinforcing ring 7 into a whole effectively improves the overall strength and rigidity of the inner floating disc body 6.

[0034] When in use, this utility model effectively increases the buoyancy of the steel single-disc inner floating plate through the inner floating basin 11 and the hollow cylinder 8 set on the outside, so that it floats stably on the liquid surface in the oil tank in a fully liquid-contact form for a long time, preventing the oil from evaporating. The inner reinforcing ring 2, the outer reinforcing ring 7 and the reinforcing plate 3 effectively improve the overall strength and rigidity of the floating plate, making it less prone to deformation and durable.

[0035] The sealing ring 5 is used to improve the sealing between the inner floating roof body 6 and the inner wall of the oil tank, avoiding gaps that would affect the performance.
