Abstract

The utility model belongs to the field of chemical product storing devices and discloses a double-layer storing tank. Apart from traditional arrangement of an inner tank and an outer tank, trapezoid-shaped reinforcement ribs are arranged in an annular gap between the inner tank and the outer tank and used for bearing the inner tank and the outer tank of the double-layer storing tank. The inner tank, the outer tank and the reinforcement ribs form a whole. The gap of the middle layer of the double-layer storing tank is larger, a regular dry type or wet type leak-proof monitoring system can be conveniently used, the comprehensive strength and rigidity are good, the manufacturing cost is low and measuring leakage is convenient to perform.

Description

A kind of double-layer storage tank

Technical field

The utility model relates to chemicals storage facilities field, discloses a kind of double-layer storage tank.

Background technology

At present, traditional double-layer storage tank is the 3D composite technology to be applied to the interlayer of SF double-layer tank or FF double-layer tank, make between the storage tank inner and outer tank to form the interlayer sky that ultimate range that structure is communicated with is no more than 3.5 millimeters and have a rest, and utilize the internal outer field leakage of having a rest of this sky to be monitored.Because this kind of double-layer storage tank interlayer sky had a rest too narrow and small, and complex manufacturing, productive costs is too high, simultaneously, in this kind of storage tank being carried out to the testing process of seepage whether, need the external expensive monitoring equipment that leaks hunting of import, virtually again increased user's cost, the double-layer storage tank of traditional employing 3D composite technology not only is not suitable for China's national conditions instantly, and is unfavorable for the extensively popularization at home of this technology.

The utility model content

The purpose of this utility model is: for the defect of above-mentioned traditional double-layer storage tank, provide a kind of novel double-layer storage tank, not only production technology is simple, low production cost, and the inspection of can being leaked hunting very easily, the additional expense that the user is expensive without burden.

To achieve these goals, the technical solution of the utility model is:

A kind of double-layer storage tank, comprise outer tank, be arranged on outer tank inside inner canister, be provided with annular space between outer tank and inner canister, wet type or dry type environment can be set in annular space, convenient adopt the measure of leaking hunting accordingly.It is characterized in that, also comprise the hole of leaking hunting be arranged on outer tank; Be arranged on air extractor vent and personnel's services aperture on inner canister; And be arranged on inner canister inside, and run through input hole, delivery orifice and the gage hatch of outer tank; Also be provided with trapezoidal reinforced rib in order to accept inner and outer tank in upper and lower two-layer annular space between outer tank and inner canister, make inner canister, reinforced rib and outer tank become as a whole, when applying external force, integral body is jointly stressed, has increased structural strength and the rigidity of storage tank.

As a kind of optimal way, interior pot bottom of the present utility model also is provided with Crashworthy plate.

As a kind of optimal way, the magnitude setting of trapezoidal reinforced rib of the present utility model is 2-10.

As a kind of optimal way, outer tank of the present utility model can adopt glass-reinforced plastic material, and inner canister can adopt glass-felt plastic or steel.

Owing to having adopted above technical scheme, the beneficial effects of the utility model are:

The utility model double-layer storage tank can well solve the individual layer storage tank due to liquid storage and electrochemical corrosion to the corrosion of steel storage tank, cause service life short, and very easily cause and leak and the problem of potential safety hazard.

With traditional double-layer storage tank, compare, interlayer sky of the present utility model is had a rest larger, can reach more than 100 millimeters, can be convenient to use conventional dry type or wet type anti-leak monitoring system, and strength and stiffness of the present utility model be better, manufacturing cost is cheaper, leak hunting easy to detect, inner and outer tank of the present utility model can adopt glass-felt plastic or steel manufacture, smooth outer surface, can be more prone to double-deck underground storage tank is carried out to the sandy soil backfill construction, guarantee the construction quality of sandy soil backfill.

Mark in figure: 1-outer tank, 2-inner canister, 3-wet type or dry type annular space, the 4-hole of leaking hunting, 5-air extractor vent, 6-input hole, 7-delivery orifice, 8-gage hatch, 9-personnel services aperture, 10-Crashworthy plate, the trapezoidal reinforced rib of 11-, 12-saddle

The specific embodiment

Embodiment 1:

With reference to Fig. 1, a kind of double-layer storage tank, comprise outer tank 1, be arranged on outer tank 1 inside inner canister 2, be provided with annular space 3 between outer tank 1 and inner canister 2, it is characterized in that, also comprise the hole 4 of leaking hunting be arranged on outer tank 1; Be arranged on air extractor vent 5 and personnel's services aperture 9 on inner canister 2; And be arranged on inner canister 2 inside, and run through input hole 6, delivery orifice 7 and the gage hatch 8 of outer tank 1; Also be provided with trapezoidal reinforced rib 11 in upper and lower two-layer annular space between outer tank 1 and inner canister 2 in order to accept inner canister 2 and outer tank 1.The inside bottom of inner canister 2 of the present utility model also is provided with Crashworthy plate 10.The magnitude setting of trapezoidal reinforced rib 11 of the present utility model is 6, is uniformly distributed and is arranged at two-layer up and down between outer tank 1 and inner canister 2.Outer tank 1 of the present utility model and inner canister 2 all adopt glass-felt plastic to make.

In use, at first the utility model is imbedded undergroundly, be fixedly mounted on cement saddle 12, the utility model smooth outer surface, can be more prone to double-deck underground storage tank is carried out to the sandy soil backfill construction, guarantees the construction quality of sandy soil backfill.Owing to being provided with Crashworthy plate 10, the utility model more can stand the impact from saddle 12 or other hard things, after imbedding and having constructed, can be inputted stock by input hole 6, delivery orifice 7 is carried stock, and air extractor vent 5 can carry out ventilation for inner canister 2, and gage hatch 8 is in order to measure the volume of stock, the aperture of personnel's services aperture 9 and human body fit, the convenient for maintaining personnel enter in tank body and carry out maintenance maintenance.Wet type or dry type environment can be set in annular space 3, conveniently adopt the measure of leaking hunting accordingly, because annular space 3 diameters of the present utility model are larger, can reach more than 100 millimeters, can be convenient to use conventional dry type or wet type anti-leak monitoring system, and the strength and stiffness of the utility model double-layer tank are better, manufacturing cost is cheaper, leaks hunting easy to detect.
