Description
Technical field
The present invention relates to Large Oil Tank, particularly external floating top tank double plate buoyancy module method and device.
Background technology
The floating top of double plate mainly by floating top top board, float roof and floor, boundary plank, hoop dividing plate, radially dividing plate and reinforced frame etc. are formed.Floating roof and floor is a level, and top board has certain drainage grade.For the smaller storage tank of diameter, the top board gradient entad is, floating top is central minimum, i.e. the floating top of V-arrangement; For the bigger storage tank of diameter, the top board gradient is a beidirectional, i.e. the floating top of W shape.Floating top central authorities and edge are higher, and main purpose is to avoid top board lowest part floating top thickness degree in floating top too little, to make things convenient for welding procedure.For the floating top of large-scale storage tank, the top board gradient can be made multidirectional, and promptly the top board shape is a plurality of V-arrangement ripples.The effect of boundary plank is to seal around the edge of top board, base plate, forms a big circular cabin, makes it to swim on the liquid level.The effect of hoop dividing plate is circumferentially to separate cabin, makes each annulus all become an independent cabin, and increases the rigidity of floating plate.Radially dividing plate is welded between top, base plate and the hoop dividing plate, makes the hoop dividing plate be separated into littler closed cabin, when the base plate local leakage, can not cause scurrying the cabin, causes the sinking of floating top.In order to increase the load-carrying capacity and the resistance to overturning on floating top, in each enclosed compartment, be provided with reinforced frame.
Because outer floating roof structure all is to be designed to integral body, manufacturing work is all carried out at the scene, and work capacity is very big, the labour intensity height, and execution conditions are abominable.Any cabin must not be missed, and has regulation and operating instruction now and requires: in case leakage appears in certain cabin, and necessary stop production to overhaul; Need carry out jar processing clearly during maintenance, directly influence is produced.
Summary of the invention
The purpose of this invention is to provide a kind of being convenient to makes, safeguards that can guarantee is not again influencing under the oil tank ordinary production situation, changes external floating top tank double plate buoyancy module method and device fast.
The object of the present invention is achieved like this, and external floating top tank double plate buoyancy module method is characterized in that: all buoyancy modules on the floating top of tradition are designed to adopt bolted connection between removable independent buoyancy module, buoyancy module and the buoyancy module, and all junctions are provided with special hermetically-sealed construction.
Floating roof tank double plate buoyancy module device comprises floating top buoyancy module and foam dam, and floating top buoyancy module is linked into an integrated entity by bolt arrangement I by the concentric circles buoyancy module of various outer diameter; The internal diameter in inside and outside two the concentric circles buoyancy modules outside that is connected matches with inboard external diameter, and the center buoyancy module is a round, and foam dam is fixed on outermost layer concentric circles buoyancy module top.
The concentric circles buoyancy module of described various outer diameter connects into concentric circles by fan-shaped plate by bolt arrangement II.
The concentric circles buoyancy module of described various outer diameter is high outside and low outside, and connecting the cross section is " h " shape.
Connect by bolt arrangement I between the described fan-shaped plate buoyancy module; Between between the fan-shaped plate buoyancy module sealing is arranged.
Described foam dam and the welding of floating top buoyancy module, soft seal is adopted in the gap of the foam dam on the buoyancy module of floating top.
The concentric circles buoyancy module quantity of described various outer diameter is between 2-5.
Characteristics of the present invention are: all buoyancy modules on the floating top of tradition are designed to adopt bolted connection between removable independent buoyancy module, buoyancy module and the buoyancy module, and all junctions are provided with special hermetically-sealed construction.The whole batch production of manufacturing work on floating top can reduce field activity greatly, improve workman's work situation; In service if certain buoyancy module leakage in floating top can be prefabricated in the factory earlier, is transported to on-the-spotly directly to change, thereby has avoided the safety that traditional floating top causes because of maintenance and the stopping production problem of oil tank, guarantees the oil tank long-term use.
