Abstract
The utility model provides a kind of container turnover structure of improvement, comprise the hatch frame on container and the vessel flange affixed with this hatch frame, hatch frame place on described container by fixing device install turnover sleeve structure, and this fixing device and vessel flange seal affixed.Described turnover sleeve structure comprises inside and outsidely stretches adapter, and the inner side of this inward nozzle one end and described fixing device is affixed, and the other end extends in container; And the outside of extended pipe one end and described fixing device is affixed, it is affixed that flange imported and exported by the other end and container.Described inward nozzle stretches into the affixed diffuse fluid structure in one end in container.The utility model solves the impact on container turnover structure and neighbouring tank skin of low temperature that when medium volume sharply spreads, heat absorption is formed, improves the Security of storage tank, thus extends the working life of storage tank.
Description
Technical field
The utility model relates to a kind of container turnover structure storage tank of improvement, is mainly used in the storage of the materials such as liquefied petroleum gas (LPG), liquid oxygen, liquid nitrogen, oxygen, nitrogen, rock gas, pressurized air.
Background technique
Along with improving constantly of national economy in recent years sustained and rapid development and industrialized level, the demand of market to industrial gas liquid is increasing, the manufacture level of storage tank also just at high speed development, and these materials because of the safety requirement of feature to its storage facilities of himself also more and more higher.According to national security production regulation, each process (feasibility study, design, construction, operation run) build at storage tank and extend, using all will carry out safety evaluation, to guarantee the Security of installations and facilities.Petrochemical enterprise all needs to build large stretch of tank area and stores these materials, and the optimization of these tank structure patterns seems and is more and more necessary.The material of most of storage tank passes in and out in structure (see figure 2) and does not arrange this modified node method of air inlet sleeve pipe before, and the use of turnover structure is all normal temperature material, cause storage tank when charging, the impact of the low temperature that when its medium volume sharply spreads, heat absorption is formed on container turnover structure and neighbouring tank skin is very large, the resistance to low temperature of neighbouring tank skin cannot meet the demand in use, solution can only be that whole container material is replaced by low temperature resistant material, cause engineering cost high, unreasonable in Economy.
Model utility content
The utility model provides a kind of container import and export mix of improvement, improves the Security of storage tank and reduces its engineering cost.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of container turnover structure of improvement, comprise the hatch frame on container and the vessel flange affixed with this hatch frame, hatch frame place on described container by fixing device install turnover sleeve structure, and this fixing device and vessel flange seal affixed.
Described turnover sleeve structure comprises inside and outsidely stretches adapter, and the inner side of this inward nozzle one end and described fixing device is affixed, and the other end extends in container; And the outside of extended pipe one end and described fixing device is affixed, it is affixed that flange imported and exported by the other end and container.
Described inward nozzle stretches into the affixed diffuse fluid structure in one end in container.
Described diffuse fluid structure is conical shell.
The top of described conical shell exceeds inner surface of container 500mm.
The large end cone footpath of described conical shell is less than warp in vessel flange.
Described fixing device is non-standard flange.
The utility model solves medium volume when sharply spreading, and the low temperature that the formed impact on container turnover structure and neighbouring tank skin of absorbing heat, reduces engineering cost, improve the Security of storage tank, thus extend the working life of storage tank.And strong adaptability, can be widely used in the tank structure such as oil refinery, chemical plant.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of container turnover structure in prior art;
Fig. 2 is structural representation of the present utility model.
Embodiment
Accompanying drawing is coordinated to be further described the utility model below.
With reference to Fig. 2, a kind of container turnover structure of improvement, can for being installed on a hatch frame 7 of container 8, this container 8 can be that spherical tank etc. stores kind equipment, this hatch frame 7 is forging reinforcement by flange structure, be generally used for the open-celled structure reinforcement of heavy caliber adapter, this strengthening structure adopts local to thicken reinfm type in stress concentration portion position, butt weld is adopted with the connection of container 8, this reinforcement for openings structure 7 the other end connecting container body flange 5, vessel flange 5 is a standard flange, be connected by fastening piece 4 with for the non-standard flange 3 in fixing turnover sleeve structure, convenient to ensure product maintenance.Fastening piece 4 is bolt, nut, the pad of pairing, and turnover sleeve structure and container body portion separate by its pad, and turnover sleeve structure low temperature material used directly can be connected with vessel normal temperature material used.Outside non-standard flange 3 with extended pipe 2 by being welded to connect, extended pipe 2 and container import and export flange 1 by being weldingly connected, inside non-standard flange 3 with inward nozzle 6 by being weldingly connected, namely opposite side and the conical shell 9 with diffuse fluid structure of inward nozzle 6 are bored section and are connected, in order to reduce low temperature as far as possible to container turnover structure and the impact of neighbouring tank skin, require that the cone section top in air inlet sleeve structure at least exceeds inner surface of container 500mm, and in order to field-strip can be carried out to the turnover structure of this container, large end cone footpath must be less than warp in vessel flange 5.
Described extended pipe 2 is generally thick walled tube, and its wall thickness should be checked by calculating, and nominal diameter should be determined according to process conditions.
Air inlet sleeve structure material therefor is low temperature resistant stainless steel, and container 8 body material therefor is normal temperature steel.
When fluid is filled with container through turnover sleeve structure in the utility model, forms a structure simply and the good structure of tightness, the demand in use can be met completely.
