Abstract
The invention belongs to the field of design of fuel tanks and relates to a capsule tank with stable delivery performance, applicable to industries such as petroleum and aerospace. At the premise of not affecting the oil-storing capacity of the tank, the process of discharging the oil from the tank is changed into the process of flowing in a pipe. An oil discharge pipe is disposed within the tank by means of welding and the like and is provided with an oil outlet; the oil discharge pipe is included in a rubber capsule; the rubber capsule is attached to the inner wall of a tank body; fuel oil can be exchanged through the oil outlet and can be injected into the rubber capsule or discharged out of the same; the rubber capsule is flanged, thus having a seal structure, and the rubber capsule can be in flange connection with the end face of the tank body, ensuring end face tightness of the rubber capsule and the end face of the tank body; inertia gas is injected into a housing of the tank through a nozzle; with increase in the gas content, pressure increases gradually and compresses the rubber capsule which contracts and deforms in the middle; the fuel oil is exchanged through the oil outlet of the oil discharge pipe and is evenly discharged.
Description
Technical field
The present invention relates to a kind of discharge structure improving oil plant tank.Particularly containing a structure design for the tank of rubber capsule structure, belong to fuel oil tank design field, can be applicable to the industry such as oil, Aeronautics and Astronautics.
Background technology
The transport of the oil plant such as fuel oil, kerosene and storage, have important effect in the field such as oil, Aeronautics and Astronautics.The discharge process of usual oil plant mainly relies on the modes such as pump, piston, gas boosting to oppress oil plant and in tank, produces difference of pressure and cause flowing, discharging in casing, supply hydraulic unit and engine parts etc.But compared with pipeline transportation, due to the box shape of tank, cause this tradition oil plant flowing instability in the startup of discharging and transport and stopped process.Particularly at reservoir outlet place, form flow blind angle and turbulent flow, tank casing is produced to the effects such as pulsation, vibration and impact, cause the breakage of casing or affect the service life of tank.Simultaneously because oil plant period of storage in tank is long, the factors such as low temperature impel oil plant thickening in tank, affect the flowing of oil plant in tank discharge process, therefore need the discharge structure improving oil plant tank, improve expulsion efficiency.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, proposing a kind of capsule-type tank with stable transfer ability.
The object of the invention is to be achieved through the following technical solutions.
A kind of capsule-type tank with stable transfer ability of the present invention, comprises tank body, pipeline and rubber capsule;
The bottom of pipeline is fixedly connected with the bottom of tank body; The sidewall of pipeline is evenly distributed with oil extraction through hole;
Rubber capsule is the flexible tubular structure with upper shed and under shed, and the bottom of rubber capsule and top are all with flange;
Rubber capsule is enclosed between pipeline and tank body, the flange of rubber capsule bottom is fixed on tank body interior bottom, the flange on the top of rubber capsule is fixed on tank body top, thus by fuel encapsulation in rubber capsule, make not to be filled with fuel between rubber capsule and tank body;
Tank body arranges valve; unreactable gas is passed between rubber capsule and tank body by this valve; before filling fuels, pass into a small amount of unreactable gas by this valve between rubber capsule and tank body, protection rubber capsule avoids adhesion casing tank inner body wall.
During use, when needing the fuel in tank to discharge tank, by valve to passing into unreactable gas (less than 80 degree can be heated to) between rubber capsule and tank body, along with the increase of unreactable gas volume, pressure between rubber capsule and tank body increases gradually, and extruding rubber capsule is out of shape to middle shrinkage, and fuel is along the oil extraction through hole of pipeline, exchange, evenly discharge.
The present invention's beneficial effect is compared with prior art:
The oil plant of tank, under the condition not affecting tank storage oil plant ability, is discharged flow process, is changed pipe type flowing into by the present invention.In tank, arrange an oil-drain pipe by methods such as welding, outage settled by pipeline, pipeline is included in rubber capsule, and rubber capsule is attached in tank cabinet wall.Fuel oil can carry out the exchange of oil plant by outage, is filled into rubber capsule or therefrom discharges.Rubber capsule, by flange, increases hermetically-sealed construction, can carry out Flange joint with casing end face, ensures capsule and casing side seal.By admission piece filling with inert gas in tank body skin.Along with gas content increases, pressure increases gradually, and extruding rubber capsule is out of shape to middle shrinkage, and fuel oil, along the oil extraction through hole of pipeline, exchanges, evenly discharges.After tank oil plant is discharged and stopped, oil plant reflux the flow instabilities caused, and alleviates oil plant to reflux the impact possible on tank by the distortion of capsule.Meanwhile, for reduction temperature and period of storage are on the impact of tank oil plant discharge process, before oil plant is discharged or in discharge process, hot gas can be passed into from valve, reduce the resistance to flow of oil plant, improve oil plant from the expulsion efficiency tank.
The oil draining system structure of tank of the present invention, has made the discharge flow process of tank oil plant into Flows mode, decreases tank in oil plant discharge process because oil plant flowing instability is to infringements such as the shock and vibrations of casing.
Tank oil draining system structure of the present invention, by valve, introduces the gas with uniform temperature, promotes capsule and shrinks, form oil extraction process, can reduce the problem of the viscosity increase that oil plant causes due to low temperature, long storage periods, improve oil extraction efficiency.
Tank oil draining system preparation technology of the present invention is simple, easy for installation, can extensively promote.
Tank oil draining system of the present invention, is contacted with the direct of oil plant owing to having been completely cut off casing by rubber capsule, decreases due to the injury to tank such as electrostatic, oil plant corrosion, improve the service life of whole tank.
