Description

Technical Field

[0001] This utility model relates to the field of floating roof technology, and more specifically, to a safety sealing structure for an internal floating roof of refined oil. Background Technology

[0002] The internal floating roof safety sealing structure is a crucial component inside refined oil storage tanks. It exists in the form of a floating disc, tightly connected to the tank wall via a sealing device. During operation, this structure acts as a robust barrier, effectively preventing the evaporation and leakage of refined oil, significantly reducing safety hazards caused by oil and gas escape. Its ingenious design allows it to float flexibly according to changes in the oil volume within the tank, always maintaining a tight seal with the tank wall. This safety sealing structure not only ensures the safe operation of the storage tank but also reduces environmental pollution, improves the storage efficiency of refined oil, and provides strong support for the safe and stable development of the petroleum storage and transportation industry. However, under current technological conditions, the operation of internal floating roof tanks faces the risk of the floating roof sinking to the bottom. Once the floating roof sinks, the residual oil inside the tank will rapidly mix with the atmosphere, forming a dangerous oil and gas mixture. This mixture is highly flammable and explosive, and its characteristics mean that it can instantly ignite a fire or even explode upon encountering any ignition source. Such accidents not only pose a serious threat to the lives of personnel on site, but can also cause significant damage to equipment and facilities, leading to production stoppages. More seriously, explosions and fires can cause irreversible damage to the environment, affecting ecological balance and sustainable development. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a safety sealing structure for an inner floating roof of finished oil products, which has the advantage of sealing the inner cover by moving the floating roof up and down.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a safety sealing structure for an internal floating roof of refined oil, comprising a floating roof and a bottom plate, an inner cover fixedly installed on the top of the floating roof, a rubber gasket movably installed inside the inner cover, an outer cover fixedly installed on the top of the rubber gasket, a support leg movably installed inside the outer cover, one end of the support leg penetrating the interior of the floating roof, and a vent cap fixedly installed on the other end of the support leg.

[0005] As a preferred embodiment of this utility model, a support frame is fixedly installed between the vent cap and the outer cover, and the support frame is arranged in a circular array.

[0006] As a preferred embodiment of this utility model, a pull ring is fixedly installed on the top of the outer cover, and the pull ring is U-shaped.

[0007] As a preferred technical solution of this utility model, a limiting frame is fixedly installed inside the inner cover, and the limiting frame is in the shape of a cross.

[0008] As a preferred embodiment of this utility model, the inner diameter of the limiting frame is equal to the outer diameter of the support leg, and the interior of the limiting frame has a smooth surface design.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Compared to traditional structures, this invention cleverly achieves the switching between sealing and ventilation functions of the inner and outer covers by utilizing the suspended and bottom-touching states of the outriggers. When the outriggers are suspended, the inner and outer covers fit tightly together, effectively preventing oil and gas leakage and ensuring the tank's airtightness. When the outriggers touch the bottom, the support frame lifts the outer cover, allowing ventilation and preventing the formation of a confined space. Furthermore, this device significantly reduces the safety risks associated with the inner floating roof sinking to the bottom. The sealing design reduces contact between oil and gas and air, lowering the risk of explosion. The device also utilizes the natural weight of the outer cover to press down on the sealing device, with the bottom rubber gasket providing a basic seal to ensure no oil or gas leakage. This simple and effective design improves the safety and reliability of the storage tank, providing a solid guarantee for the storage of refined oil products. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 6 As shown, this utility model provides a safety sealing structure for an internal floating roof of finished oil products, including a floating roof 1 and a base plate 2. An inner cover 6 is fixedly installed on the top of the floating roof 1. A rubber gasket 5 is movably installed inside the inner cover 6. An outer cover 3 is fixedly installed on the top of the rubber gasket 5. A support leg 8 is movably installed inside the outer cover 3. One end of the support leg 8 penetrates the interior of the floating roof 1, and a vent cap 4 is fixedly installed on the other end of the support leg 8.

[0020] When the outrigger 8 is suspended in the air, the inner cover 6 and the outer cover 3 are in close contact, forming a sealed state and effectively preventing oil and gas leakage. When the outrigger 8 contacts the bottom plate 2, the support frame 7 will push the outer cover 3 upward, separating the inner cover 6 from the outer cover 3, thereby realizing the ventilation function. During use, the inner floating plate 1 must not sink to the bottom, because if it sinks to the bottom, the vent cap 4 will be connected to the atmosphere, and an oxygen-rich environment will be formed inside the floating plate 1. This gas, when mixed with residual oil at the bottom, can easily form flammable and explosive gases. If it comes into contact with a heat source, it can easily cause a fire or explosion. When the floating plate 1 is running normally, the outer cover 3 uses its natural weight to press down the sealing device, and the bottom rubber gasket 5 plays a basic sealing role, ensuring that oil and gas do not leak and ensuring the safe operation of the storage tank.

[0021] When the outrigger 8 is suspended in the air, the inner cover 6 and the outer cover 3 fit tightly together, forming a seal that effectively prevents oil and gas leakage and ensures the safety of the storage tank. When the outrigger 8 separates from the bottom plate 2, the support frame 7 pushes up the outer cover 3, separating the inner and outer covers and enabling ventilation to prevent internal pressure buildup. The inner floating roof 1 must not sink to the bottom, because if it does, the vent cap 4 will be connected to the atmosphere, and an oxygen-rich environment will easily form inside the floating roof. This oxygen will mix with residual oil to form flammable and explosive gases, which may cause a fire or explosion upon contact with a heat source. When the floating roof is operating normally, the outer cover 3 relies on its own weight to hold the sealing device in place, and the bottom rubber gasket 5 provides a basic seal. Compared with traditional structures, this structure cleverly achieves the switching between sealing and ventilation functions of the inner cover 6 and the outer cover 3 through the suspended and bottom-touching states of the outrigger 8. When the outriggers are suspended in the air, the inner and outer covers fit tightly together, effectively preventing oil and gas leakage and ensuring the tank's airtightness. When the outriggers touch the bottom, the support frame 7 lifts the outer cover, allowing ventilation and preventing the formation of a closed space. In addition, this device can significantly reduce the safety risks caused by the inner floating roof 1 falling to the bottom. The sealing design reduces the contact between oil and gas and air, reducing the risk of explosion. The device also uses the natural weight of the outer cover 3 to press down the sealing device, and the bottom rubber gasket 5 provides a basic sealing effect, ensuring that oil and gas do not leak. This design is simple and effective, improving the safety and reliability of the storage tank and providing a solid guarantee for the storage of refined oil products.

[0022] Among them, a support frame 7 is fixedly installed between the vent cap 4 and the outer cover 3, and the support frame 7 is in the form of a circular array.

[0023] Since the support frame 7 is arranged in a circular array on the outer cover 3 and the vent cap 4, the installation of the support frame 7 can fix the position of the vent cap 4, preventing it from loosening and falling off and causing accidents. The stable ventilation of the vent cap 4 during operation can ensure normal gas discharge and avoid the danger of pressure accumulation.

[0024] The top of the outer cover 3 is fixedly equipped with a pull ring 9, and the pull ring 9 is U-shaped.

[0025] Because the pull ring 9 is U-shaped at the bottom of the outer cover 3, and the U-shaped pull ring 9 provides a stable support point for hoisting operations, the installation and disassembly of the outer cover 3 is more convenient and efficient. It can be easily lifted or lowered with the help of hoisting equipment, which significantly improves work efficiency.

[0026] The inner cover 6 has a fixed mounting bracket 10 inside, and the mounting bracket 10 is in the shape of a cross.

[0027] Since the limiting frame 10 is fixed inside the inner cover 6 in a cross shape, and the cross-shaped limiting frame 10 effectively restricts the movement of the support leg 8 inside the inner cover 6, it prevents excessive shaking and displacement, and the fixed support leg 8 enhances the structural stability of the floating table 1, ensuring that the floating table 1 rises and falls smoothly and reducing safety accidents.

[0028] The inner diameter of the limiting frame 10 is equal to the outer diameter of the support leg 8, and the interior of the limiting frame 10 has a smooth surface design.

[0029] Since the inner diameter of the limiting frame 10 is equal to the outer diameter of the support leg 8, and the interior of the limiting frame 10 has a smooth surface design, the support leg 8 will not shift position during the up-and-down movement inside the floating plate 1 and the limiting frame 10, thus ensuring the stability of the support leg 8 during the up-and-down movement.

[0030] Working principle and usage process of this utility model:

[0031] When the outrigger 8 is suspended in the air, the inner cover 6 and the outer cover 3 are in close contact. When the outrigger 8 is in contact with the bottom plate 2, the support frame 7 will push the outer cover 3 upward, separating the inner cover 6 from the outer cover 3, thereby achieving the ventilation function. During use, the inner floating roof 1 must not sink to the bottom, because if it sinks to the bottom, the vent cap 4 will be connected to the atmosphere, and an oxygen-rich environment will be formed inside the floating roof 1. This environment, when mixed with residual oil at the bottom, can easily form flammable and explosive gases. If it comes into contact with a heat source, it can easily cause a fire or explosion. When the floating roof 1 is running normally, the outer cover 3 uses its natural weight to press down the sealing device, and the bottom rubber gasket 5 plays a basic sealing role, ensuring that oil and gas do not leak and ensuring the safe operation of the storage tank. If the floating roof sinks to the bottom, reliable safety measures must be taken.
