Description
Technical field
The utility model relates to gasoline, the diesel oil tank that car and boat are used, and particularly relates to a kind of explosion-proof fuel tank that naked light can not be blasted that runs into.
Background technology
At present, in the fuel tank that car and boat are used (spare tank, oil drum, can) gasoline or diesel oil are housed, fuel tank according to different automobile types, the gasoline or the diesel oil of Different Weight are housed, the fuel tank of this structure, after gasoline is housed, always leave certain space, inevitably there is certain air in this space, because the boil-off gas of air and gasoline exists simultaneously, forms a kind of miscellaneous gas that can burn, when running into naked light and static, miscellaneous gas in the case will burn suddenly, causes fuel tank explosion, causes the serious person and property damage to the user.
Chinese patent publication number: CN2354804 provides a kind of " explosion-proof fuel tank ".In tank envelope, set up the aluminum alloy explosion-proof lamp, and the explosion-proof lamp of " netted and net shape " is processed into column type, sheet type and ball-shaped, layering is packed in the fuel tank, set material occupies most spaces of fuel tank capacity, therefore, air just can not be a large amount of enter in the fuel tank, the limit degree of the boil-off gas of oil plant and the blast of air-blending concentration out of reach, overcome contingent explosion accident when running into naked light, electrostatic spark, guaranteed the safety of user's person, property.
The utility model content
The purpose of this utility model is: a kind of explosion-proof fuel tank is provided, change and intercept explosion-proof aluminum-foil netted shape and fixed form, improve and intercept explosion-proof aluminum-foil netted coefficient of fullness in fuel tank, prevent to intercept explosion-proof aluminum-foil netted rocking, suppress generation of static electricity, when improving the oil tank anti-explosion performance, the conveniently assemble and disassemble oil plant, prevent that foreign material from entering, prevent to intercept and explosion-proof aluminum-foil nettedly in loading and unloading oil plant process, overflow from the fuel tank oil inlet.
The technical solution adopted in the utility model is: explosion-proof fuel tank, mainly form by fuel tank casing, isolated tube and obstruct are explosion-proof aluminum-foil netted, it is characterized in that: have obstruct explosion-proof aluminum-foil netted in the fuel tank casing, intercept explosion-proof aluminum-foil netted being fixed in the fuel tank casing, and intercept explosion-proof aluminum-foil netted being full of in the whole fuel tank casing; Oil inlet at fuel tank is fixed with isolated tube, and isolated tube is in the fuel tank casing.Have to intercept explosion-proof aluminum-foil netted description in a plurality of patent applications, those skilled in the art know.The obstruct that is provided with in the fuel tank casing is explosion-proof aluminum-foil netted, most spaces of occupying fuel tank capacity, space in the fuel tank casing will be intercepted explosion-proof aluminum-foil netted several " honeycomb " shape cells that is divided into, but do not influence flowing of oil plant self, when the air admission fuel tank with after the volatilization gas of bunker oil mixes, will be cut apart by " honeycomb " shape cell, make the limit degree of the concentration out of reach blast of fire gases, in case run into naked light, it intercepts explosion-proof aluminum-foil netted will the absorption effectively and conducts the most of heat that discharges when burning, temperature in the fuel tank increases little, thereby has prevented the generation of fuel tank explosion accident effectively.Described fuel tank comprises fuel tank, oil drum, the oil plant container of metal case.
The explosion-proof aluminum-foil netted thickness of described obstruct is between 0.020～0.025 millimeter.Because obstruct is explosion-proof aluminum-foil netted thinner than like product, will be compacter in fuel tank, " honeycomb " shape cell that splits will be more, have outstanding explosion-proof performance.
Described obstruct is explosion-proof aluminum-foil netted to be that banded obstruct is explosion-proof aluminum-foil netted, or spherical obstruct is explosion-proof aluminum-foil netted, or web-like intercepts explosion-proof aluminum-foil netted.
Swing, move up and down in the fuel tank casing for further the restriction obstruct is explosion-proof aluminum-foil netted, suppressing static takes place, when adopting the explosion-proof aluminum-foil netted or web-like of spherical obstruct to intercept when explosion-proof aluminum-foil netted, explosion-proof aluminum-foil netted or web-like intercepts in spherical obstruct has interlayer between explosion-proof aluminum-foil netted, and described interlayer comprises horizontal interlayer and vertical interlayer.
Described isolated tube is cylindric, isolates on the tube wall to be evenly distributed with aperture.Explosion-proof aluminum-foil netted or the web-like of spherical obstruct intercepts explosion-proof aluminum-foil netted can not entering in the isolated tube, prevents from loading and unloading oil plant process that the explosion-proof aluminum-foil netted or web-like of spherical obstruct intercepts explosion-proof aluminum-foil nettedly to overflow from the fuel tank oil inlet.Also can prevent that foreign material from entering in the fuel tank adopting banded the obstruct on the explosion-proof aluminum-foil netted fuel tank to use.
Described isolated tube is a coil spring.Explosion-proof aluminum-foil netted or the web-like of spherical obstruct intercepts and explosion-proof aluminum-foil nettedly can not enter coil spring inside, prevents from loading and unloading oil plant process that the explosion-proof aluminum-foil netted or web-like of spherical obstruct intercepts explosion-proof aluminum-foil nettedly to overflow from the fuel tank oil inlet.
The beneficial effects of the utility model: the utility model explosion-proof fuel tank, can play explosion-proof, when the air admission fuel tank with after the volatilization gas of bunker oil mixes, will be cut apart by " honeycomb " shape cell, make the limit degree of the concentration out of reach blast of fire gases, solved the explosive problem of fuel tank, can also prevent to intercept and explosion-proof aluminum-foil nettedly in loading and unloading oil plant process, overflow from the fuel tank oil inlet.Simple in structure, safe and reliable, cheap for manufacturing cost, easy to utilize.
