Description
Technical field
The present invention relates to gas station with sunken tankers technical field and in particular to a kind of composite two-compartment oil tank and its system
Make method.
Background technology
In recent years, with the high speed development of national economy, the steadily improving of living standards of the people, traffic transport industry is swift and violent
Development, automobile pollution increases substantially, and large-scale oil enterprise strengthens gas station's network construction at home energetically, national every year newly-built
The thousands of seat in gas station.With the progress of China's expanding economy and society, the environmental consciousness of people is more and more stronger, and country is to environmental protection
Requirement also more and more higher.At present, the gas station of most domestic is all using underground metalliferous individual layer oil tank, due to oil tank itself
The mechanical damages such as scratch, cut, impression, the quality problems during tank body welding and sunken tankers external anti-corrosion layer are older old
Change, lose protective effect, steel tank inner surface can not can bring about ring fully against the corrosion of fuel oil once there is seepage
Border pollution or the serious consequence of underground harm water resource.And because the iron oil tank of individual layer is embedded in underground, is subject to underground throughout the year
The corrosion of water and electrolytic etching, the iron oil tank of individual layer has obvious potential safety hazard in use quality and service life, is related to
To safety, economy, environmental protection.Additionally, individual layer irony oil tank is required for being keeped in repair and detecting every year, also increase maintenance time and
Cost.
Two-compartment oil tank has the unrivaled safe and environment-friendly, economic performance than common individual layer steel oil tank, and country is big at present
Push the application of row two-compartment oil tank, prior art outer tank typically adopts glass steel material to make, and inner canister is steel material so that interior
Housing has reinforcement and supports, and outer tank has insulation effect such as patent document CN 104816897A and CN 102582980B institute public affairs
The two-compartment oil tank opened, but due to inner canister for steel body material so that its weight greatly increases, impact is carried and is installed, and it is resistance to
Erosion effect is also poor, and the life-span is shorter, automatic recovery of can not rebounding after steel inner canister local compression.
In existing at present nonmetallic two-compartment oil tank, in manufacturing process adopt former matched moulds technique, product external surfaces according to
Pattern has surface forming, and inner surface relies on artificial roll forming, thus the tank body being obtained presents smooth outer surface, inner surface
Coarse phenomenon.Tank inner surface is contacted with oil product, and its inner surface is more coarse, the friction of the tank inner surface contacting with oil product
Resistance is bigger, and inner surface worn composite is faster, when loading and unloading oil product, repeatedly tank inner surface is rushed for a long time
Hit, abrasion can be caused to come off to forming repeated stock at tank inner surface microcosmic injustice, reduce oil quality；Additionally, former system
The product made, its tank inner surface compactness is poor, laminated between combine closely, easily make the gas or liquid microcosmic by surface
Trench penetrates into composite inner, causes surface corrosion.When used over time, its inner surface can occur part particle detachment existing
As oil supply brings new composition, badly influences the quality of storage oil.
Content of the invention
Therefore, the technical problem to be solved in the present invention is to overcome that steel wall oil tank corrosion resistance of the prior art is poor, uses
Short life, installation difficulty are big, can not rebound after local pressure deformation the defects such as recovery automatically, and existing nonmetallic two-compartment oil tank exists
There is a problem of during Long-Time Service having a strong impact on oil quality, thus providing a kind of composite two-compartment oil tank and its making
Method.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that：
