Embodiment 1
[0036] Embodiment 1 of the present invention describes a floating disk module.
[0037] Such as figure 1 As shown, the floating disk module includes components such as an upper cover 1 , a hexagonal honeycomb core 2 and a lower cover 3 .
[0038] Wherein, the six-sided honeycomb core 2 is located between the upper cover plate 1 and the lower cover plate 3 .
[0039] A plurality of evenly distributed, independent and discontinuous honeycomb holes are arranged on the hexagonal honeycomb core 2 .
[0041] The upper cover 1 , the lower cover 3 and the hexagonal honeycomb core 2 in the first embodiment are all made of aluminum alloy.
[0042] The upper cover plate 1 is welded to the top of the hexagonal honeycomb core 2 to form a seal, and a welding spot 4 is formed after welding.
[0043] The lower cover plate 3 is welded to the bottom of the hexagonal honeycomb core 2 to form a seal, and a solder joint 4 is formed after welding...
[0047] All-welded all-aluminum honeycomb inner floating plate, including the main beam and multiple floating plate modules. Wherein, the floating disk module in Embodiment 2 adopts the floating disk module in Embodiment 1 above.
[0048] Wherein, the adjacent floating disc modules are connected by bolts to form a seal.
[0049] The main beam is in the shape of "Ji", and the main beam and the floating plate module are connected by bolts to form a seal.
[0050] In Embodiment 2 of the present invention, the leakage points inside the floating plate module, between the floating plate modules, and the connection between the floating plate module and the main beam are targeted to reduce the emission of VOCs to the greatest extent, and achieve energy saving and environmental protection.
[0051] The connection structure between the floating plate module and the main beam is described below: ...
Embodiment 3
[0079] Embodiment 3 describes an installation method of an all-welded all-aluminum honeycomb inner floating plate.
[0080] This installation method is aimed at the all-welded all-aluminum honeycomb inner floating plate as in the above-mentioned embodiment 2, and includes the following steps:
[0081] The sealed connections between adjacent floating disc modules 2-1 and between the floating disc modules 2-1 and the main beam 2-5 are realized in sequence.
[0082] In Example 3, through the above installation method, the installation of the all-welded all-aluminum honeycomb inner floating plate is well realized, and at the same time, it can ensure that the gaps between the floating plate modules are sealed, thereby preventing oil and gas from escaping.

Abstract
The invention discloses an installation method of an all-welded all-aluminum honeycomb type inner floating tray. The all-welded all-aluminum honeycomb type inner floating tray comprises a girder and aplurality of floating tray modules. Each floating tray module comprises an upper cover plate, a lower cover plate and a hexagonal honeycomb core located between the upper cover plate and the lower cover plate, wherein the upper cover plate, the lower cover plate and the hexagonal honeycomb core are all made of an aluminum alloy material; and the upper cover plate is welded to the top of the hexagonal honeycomb core to form seal, and the lower cover plate is welded to the bottom of the hexagonal honeycomb core to form seal. The two adjacent floating tray modules are connected through bolts toform seal. The girder is connected with the floating tray modules through bolts to form seal. Sealing connection between the adjacent floating tray modules and between the floating tray modules and the girder is realized in sequence. Through the installation method of the all-welded all-aluminum honeycomb type inner floating tray, the problem of potential safety hazards existing in an existing floating tray technological form and the problem of oil and gas leakage can be controlled and solved, and therefore, the all-welded all-aluminum honeycomb type inner floating tray can meet use requirements under any extreme condition.
Description
technical field [0001] The invention belongs to the technical field of safety management of light oil atmospheric pressure storage tanks and energy saving and emission reduction, and in particular relates to an installation method of an all-welded all-aluminum honeycomb inner floating plate. Background technique [0002] The floating roof technology in lightweight atmospheric storage tanks needs to solve the following technical problems: [0003] 1. Reduce the concentration of oil and gas inside and around the storage tank, thereby eliminating potential safety hazards in the tank area; [0004] 2. Through the blocking effect of the floating roof technology, the loss of volatilization and dissipation of oil products is reduced, so as to achieve economic benefits and environmental protection benefits. [0005] The update process of the floating roof technology for lightweight atmospheric storage tanks is from the iron floating warehouse type inner floating plate to the plywoo...
