Abstract
Disclosed is an aluminium inner floating roof assembled form groove-shaped basins, relating to a device used for preventing volatilization of oil products. A tank body is provided with a storage tank loading and unloading port and a manhole; a buoyancy element comprises a plurality of semicircular arc groove-shaped floating basins, and is provided with a floating roof guide device, an oil metering port and an automatic breather valve; floating roof channel boards are arranged between the floating basins; the floating roof channel boards are connected with a floating basin frame; the floating basin frame and each floating basin are arranged in the shape of the Chinese character jing(well) or in the form of a small rectangle; and each floating basin is provided with a plurality of partitions. When the aluminium inner floating roof is in work, the oil enters the storage tank and when the oil liquid reaches certain height of the floating basins, due to the buoyancy, the floating roof begins to float on the surface of the oil. The floating roof moves up and down along with the oil liquid level to isolate the oil in the storage tank with the air all the time so as to prevent the volatilization of the oil. The aluminium inner floating roof is simple in structure, compact in structure, strong in overall strength, low in cost, reliable in performance and high in oil saving efficiency, and is convenient to install, simple to operate and convenient to maintain and has strong capabilities of resisting sinking and sweeping in the tank.
Description
Technical field
The utility model relates to a kind of device that prevents the oil product volatilization.
Background technology
Oil product in petrol storage tank highly volatile in storage process need be sought a kind of energy-efficient device and prevent its volatility.The keystone configuration of original floating pipe type floating plate is floating pipe, framework, bed board, pillar, provides buoyancy by floating pipe.Floating pipe diameter 180mm, the general 1.5～4m of length, the general shop of framework and the floating pipe top alloy aluminium sheet that 0.5mm is thick, 1.2～1.4m is wide, from using and overhauling through examining, the major defect of floating plate is that sealing property is not good enough in the floating pipe type, and structural strength is not enough, and anti-oil gas impact property is poor.
The applicant's patent " a kind of oil tank aluminium floating plate " (Chinese patent 02222451.3), comprise upper and lower Vierendeel girder, cover plate, girth sheets and floating drum that the upper and lower crossbeam of " ㄇ " shape, longeron, strength beam constitute, logical bolt of upper and lower Vierendeel girder and cover plate are affixed, and floating drum is with the keg float holder outward.The floating drum on floating drum holder two ends and floating drum top folder both sides are affixed, and it is affixed that floating drum presss from both sides the set a roof beam in place both wings of girder of two clamp holders and lower frame.Back portion at the corresponding upper and lower strength beam of two cover plate bar clinchs is designed to mutual cooresponding machicolated form, and male and fomale(M﹠F) is designed to dentation, and strength beam back hole and cover plate cylindrical void are affixed by bolt up and down.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide that a kind of simple in structure, facility compact, floor area are little, simple to operate, reliable operation, easy to maintenance, groove basin build-up type aluminum inner floating roof that separation efficiency is high.
The implementation of the utility model purpose is, groove basin build-up type aluminum inner floating roof, tank body has the storage tank overside port, inspection manhole, advance a jar manhole, interior buoyancy elements is made of the floating basin of a plurality of semi arch flute profiles, buoyancy elements is provided with the guide piece on floating top, gauge hatch, automatic connection for bbreather pipe, lay floating top channel plate between floating basin and floating basin, floating top channel plate is connected with the floating plate skeleton, become groined type or little quadrangle between floating plate skeleton and each floating basin, in the floating basin a plurality of partitions are arranged, the floating plate skeleton by jar at the bottom of on shore supports, between floating plate skeleton and tank body girth sheets is arranged, sealing band, lead electrostatic cable and anti-rotation device.
During the utility model work, oil product enters, when the oil product liquid level in entering storage tank reaches the certain altitude that floods floating basin, because the floating top of buoyancy function just swims on the pasta.Move up and down along with the lifting of oil product liquid level, make oil product and air in the storage tank remain isolation, thereby play the effect that stops oil evaporation, environment purification, minimizing disaster hidden-trouble in the storage tank.
Floating top of the present utility model channel plate and the floating plate frame that spreads out is connected with stainless steel bolt, and the floating basin of half-arc groove does not vertically have weld seam, and most of face of weld does not contact with liquid storage, prevents and avoided the corrosion of weld seam, has prolonged the service life of floating basin; Flute profile, floating basin top is shrouding not, allows the floating basin of part to lose efficacy, and does not influence the normal operation in floating top, and the ability of anti-floating top sinking is strong, and maintenance has intuitive; Lay channel plate between floating basin and floating basin, be convenient to I﹠M; Be convenient to I﹠M; Skeleton and floating basin form groined type, quadrilateral structure, make the structural strength on floating top big, good stability, setting accuracy height, have improved the anti-card of integral body of floating plate, anti-heavy ability; Groined type, quadrilateral structure are cut apart liquid level, make liquid level form the little air chamber of many rectangles, and little air chamber has shock damping action preferably to the liquid fluctuating of generation in service, can absorb the impulsive force that produces when transporting and guarantee that inner floating roof operates steadily; Floating basin spreads out at floating plate below the frame, because the antagonistic force of buoyancy, tie bolt can not become flexible; Distance between floating top channel plate and the liquid level is little, medium volatilization space is few.
The utility model is simple in structure, facility compact, integral structure power are strong, and cost is low, easy for installation, simple to operate, reliable operation, easy to maintenance, and the purging ability is strong in the fuel-saving efficiency height, anti-heavy ability and anti-jar.
Description of drawings
Accompanying drawing is the utility model structural representation,
The specific embodiment
With reference to accompanying drawing, tank body 5 has storage tank overside port 1, inspection manhole 9, advance jar manhole 16, buoyancy elements in the tank body is made of the floating basin 2 of a plurality of semi arch flute profiles, buoyancy elements is provided with the guide piece 3 on floating top, gauge hatch 4, automatic connection for bbreather pipe 10, lay floating top channel plate 13 between floating basin and floating basin, floating top channel plate 13 is connected with floating plate skeleton 6, become groined type or little quadrangle between floating plate skeleton 6 and each floating basin 2, in the floating basin 2 a plurality of partitions are arranged, floating plate skeleton 6 is by the shore supports on 15 at the bottom of the jar, and 5 of floating plate skeleton and tank bodies have girth sheets 7, sealing band 8, lead electrostatic cable 11, anti-rotation device 12.
Floating plate skeleton 6 adopts the special-shaped aluminium of monolithic extruded moulding, links to each other with floating Pengcheng's groined type, and integral structure power is strong.Guide piece 3 adopts polytetrafluoroethylmaterial material, and sealing and resistance to abrasion are good.Girth sheets 7 adopts monolithic extruded moulding on every side, and rigidity is strong, is used for overcoming the friction that floating plate produces between operational process sealing band 8 and tank wall, also increases near the rigidity of structure of sealing band simultaneously, thereby has guaranteed the safe in operation of sealing band.Sealing band 8 adopts double-deck liquid-filled sealing.
