Abstract

The utility model discloses a single-disc assembled box-type aluminium alloy internal float disc, which has advantages: flat and long sealed boxes made of thin aluminium alloy are positioned in array within the prior tank. The single-disc assembled box-type round float disc is formed by a beam and a surrounding frame. The joints of the float disc are glue-sealed and the surrounding frame has tongue-shaped strip seals. Over the float disc are a disc inlet, a disc blowhole, an oil gauge and a static electricity conductor while under the disc are a plurality of disc stabilizers.

Description

Single-deck is assembled floating plate in the box aluminum alloy

Technical field: the utility model relates to the oil tank technical field, in the oil tank floating plate is set specifically, and oil product stores and wherein reduces oil evaporation, is widely used in the industries such as petrochemical complex that oil product stores.

Background technology: study the central topic one that oil product stores at present; be how to reduce the evaporation loss of oil product in storage process; enter the overall process of consumption from the finished oil that recovers the oil; the total loss of oil product is in 3～5% scopes; wherein the evaporation loss in the storage of oil product accounts for half of overall loss; therefore people for this reason and sense is uneasy, this phenomenon be unfavorable for energy-conservation and to external world environment can not play a protective role.

Summary of the invention: the utility model purpose provides oil product and is stored in the oil tank and can eliminates the oil evaporation space, reduce the evaporation loss of oil product and eliminate the gas compartment that exists between former floating drum and the cover plate and oil tank when purging impact and a kind of single-deck of damaging floating plate is assembled floating plate in the box aluminum alloy.

For finishing the technical scheme that above-mentioned purpose is taked: in existing oil tank, become the prolate seal casing to arrange mutually as buoyancy tank by thin alloy aluminum leather, and fixedly form the floating plate that single-deck is assembled box circular configuration by crossbeam and peripheral frame, the floating plate slewing arrangement of setting up defences, each junction of floating plate upper surface is established sealant and is applied, the ligulate sealing band is established in the peripheral frame outside, above floating plate, be provided with simultaneously the floating plate hand-hole, the floating plate connection for bbreather pipe, oil-measuring apparatus and static conducting device, several floating plate supporting legs are established in the floating plate below, fix the floating plate of forming circular configuration by pressing plate and rivet between above-mentioned buoyancy tank and the buoyancy tank and between buoyancy tank and the peripheral frame, above-mentioned anti-rotation device two ends are arranged at oil tank top and tank bottom respectively, and above-mentioned tank dip hatch and oil-measuring apparatus are the upright position.

The utility model can be eliminated the volatilization space of oil product substantially owing to wholely forms smooth single-deck by a plurality of buoyancy tanks and assemble box floating plate and directly float on the highly volatile oil product liquid level, and the planarization of floating plate improves the impact resistance when strengthening the oil tank purging simultaneously.
