Problems solved by technology

However, due to the gradual emergence of potential safety hazards that the aluminum floating plate structure is easy to corrode and difficult to clean, the relevant national departments and local governments require the petrochemical system to phase out the aluminum floating plate structure and replace it with a safer and more reliable steel floating plate structure
[0004] In view of the related technologies mentioned above, the inventor believes that the steel floating tank has a large volume and weighs tens to hundreds of tons, which is far more than the original aluminum floating structure, and the difficulty of construction is greatly increased.

Embodiment 1

[0052] Such as figure 1 and figure 2 As shown, a steel floating plate of an inner floating roof tank includes a floating cabin 1 , a plate 2 and a sealing member 3 , and the floating cabin 1 includes several arc-shaped floating sections 11 .

[0053] Such as image 3 and Figure 4 As shown, the floating section 11 can have three, ten, twelve, etc., the floating tank 1 in the present embodiment includes twelve floating sections 11, and the twelve floating sections 11 are sequentially welded to form an annular floating tank 1 , and each floating section 11 is provided with a floating cavity 111 .

[0054] Such as Figure 4 and Figure 5 As shown, the inner wall of the ring outside the floating section 11 is integrally connected with an arc-shaped welding support platform 114; there are several disc plates 2, and the end walls of several disc plates 2 are welded on the upper surface of the welding support platform 114, and adjacent to each other at the same time. The disc ...

Embodiment 2

[0069] Such as Figure 9 As shown, a steel floating plate of an inner floating roof tank, the difference between embodiment 2 and embodiment 1 is that: the bottom end of the outer peripheral wall of the inner pipe 41 is integrally connected with a connecting ring plate 412, and a connecting piece is installed on the connecting ring plate 412 6.

[0070] Such as Figure 10 As shown, the connector 6 includes a snap ring bag 61, a connecting bag 62, a fixed rope 63 and a sealing mouth 64. There are at least two connecting bags 62, and there may be two, three and four connecting bags. There are four connection bags 62 in the example and they are evenly distributed on the top of the snap ring bag 61. The connection bag 62 is provided with a vent 621, and the sealing mouth 64 is plugged into the vent 621 and pressed tightly. The fixed ropes 63 are one by one. Fixedly connected to the connecting bag 62, the connecting ring plate 412 is provided with four connecting through grooves ...

Abstract

The application relates to a steel floating plate of an inner floating roof tank and its construction method. The steel floating plate includes a floating cabin, a plate and a sealing member. The floating cabin includes several floating sections, and the floating section is provided with The cavity, several floating sections are connected end to end in turn, the disc plate is arranged between the inner peripheral walls of the ring outside the floating tank, and the sealing member is arranged on the outer peripheral wall of the ring outside the floating tank. The application can realize fast and efficient construction of the steel floating tray.

Description

technical field [0001] The present application relates to the field of inner floating roof tanks, in particular to a steel floating plate for inner floating roof tanks and a construction method thereof. Background technique [0002] The inner floating roof tank is a kind of storage tank. It mainly places a top cover made of special lightweight materials based on its section size, which can move up and down with the increase or decrease of the internal objects; because the inner floating roof tank The top cover, that is, the inner floating plate, floats on the liquid surface, so that the liquid phase has no evaporation space, so it can reduce the evaporation loss of the liquid phase by 85-90%, and can also reduce the pollution of the air to the liquid phase, and due to the liquid phase There is no gas space above the page, which can reduce the shock of the liquid phase during transportation, thereby reducing the impact of the liquid on the inner wall of the tank and prolongin...
