Description

High-strength floating bin type inner floating roof

Technical Field

The utility model relates to a reduce volatile interior floating roof of storage tank stock solution, in particular to high strength floats storehouse formula interior floating roof.

Background

The inner floating roof is a floating roof floating on the liquid level of the oil storage tank and ascending and descending along with the oil product. The oil storage tank adopts the inner floating roof to cover the liquid surface in order to reduce the oil evaporation loss to the maximum extent and reduce the environmental pollution, which is the most ideal economic and simple method for reducing the oil evaporation loss.

The buoyancy elements of the floating tops, namely the floater units are cuboid floater units which are generally welded by aluminum alloy or stainless steel plates, the inner cavities of the cuboid floater units are hollow or filled with aluminum alloy honeycomb cores, the internal hollow floater units have low rigidity, and the floater units can not provide buoyancy completely after the shells of the floater units are corroded and damaged. The mode of filling the aluminum alloy honeycomb core is helpful for improving the rigidity of the floater unit, but after the shell of the floater unit is corroded and damaged, because the aluminum alloy honeycomb core is low in thickness and the bonding strength of the honeycomb core and the shell is easily influenced by a storage medium, namely a degumming phenomenon is generated, the reliability is poor, and the safety is still insufficient.

In addition, most of the peripheral part of the inner floating roof is influenced by the weight of the inner floating roof and the sealing friction force of the inner floating roof. The peripheral part of interior floating roof is bigger to the needs of buoyancy, and the liquid floating roof is connect entirely to the assembled at present, its float height is whole unanimous, the float lower surface is the horizontality, will cause the peripheral part of interior floating roof to be great because the atress when interior floating roof rises like this, the peripheral part float of interior floating roof can immerse the liquid level darker, and inside float is because the atress is less and immerse the liquid level shallower, can produce great examination to the whole rigidity of interior floating roof like this, if interior floating roof rigidity is not enough, then can cause interior floating roof local collapse, further lead to the sunken dish of interior floating roof.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the utility model provides a floating roof which is more reasonable in stress, good in buoyancy effect, free of maintenance, long in service time and high in overall strength.

The to-be-solved technical problem of the utility model is realized through following technical scheme: the utility model provides a high strength floats storehouse formula internal floating roof, characterized by: at least comprises the following steps: the sealing unit is arranged at the outermost ring of the outer ring floater unit, the outer ring floater unit is annularly arranged, the outer ring floater unit is arranged at the outer ring of the inner ring floater unit, the outer ring floater unit and the inner ring floater unit are of a segmented structure, the lower parts of the outer ring floater unit and the inner ring floater unit of the segmented structure are connected with the vertical supporting legs, the inner ring floater unit is arranged at the central position of the oil storage tank, the height of the outer ring floater unit is larger than that of the inner ring floater unit, the upper planes of the outer ring floater unit and the inner ring floater unit are in the same horizontal plane, and the lower part of the outer ring floater unit is lower than that of the inner ring floater unit.

The outer ring floater unit and the inner ring floater unit are connected by a segmented structure, and are concentric.

The utility model has the advantages that:

1. because the outer ring float unit of the inner floating roof is higher than the inner ring float unit, and the lower part of the outer ring float unit is lower than the inner ring float unit, the outer ring float unit can provide more buoyancy for the outer edge part of the floating roof, so that the stress of the floating roof is more reasonable, and the floating roof cannot deform and damage the inner floating roof due to the larger sealing weight of the outer edge.

2. Because the shell of the float unit is made of aluminum alloy, stainless steel material or other high-strength corrosion-resistant materials, and the internal filling body of the float unit is made of closed-cell foamed polyurethane or other closed-cell foamed materials, the buoyancy effect of the float unit can not be influenced after the shell of the float unit is corroded and damaged, so that the floating roof formed by the float unit can be used for a long time without maintenance. The integral strength of the inner floating roof is effectively enhanced, the rigid connection performance is improved, the buoyancy is increased, and the stable and safe operation of the inner floating roof is ensured.
