Description
Technical field
The utility model relates to the spherical tank of the industries such as oil, chemical industry, metallurgy, medicine, particularly a kind of spherical tank supported with skirt.
Background technology
In existing spherical tank technology, spherical tank is adopted and is supported in two ways:
One adopts pillar by national standard " Steel made Ball storage Tank " GB12337, and this is a kind of supporting way widely used.The topmost shortcoming of shore supports is: spherical shell discontinuity, spherical shell local stress is higher, every root pillar bearing load is very large, and the differential settlement of each pillar additionally bears larger load by causing indivedual pillar, so pillar and spherical shell junction (a point) become dangerous area, produce very large local stress.In addition, four kinds of being connected with spherical shell of the pillar cited by GB12337 are multi-form, but actual use shows, these four kinds of structures exist significantly not enough separately respectively, as direct connection structure exists welding narrow space, not easily ensure welding quality; The support structure area adding backing plate is little, and bottom welding seam distance is near, affects weld strength; U-shaped rod structure has more right angle flex point, and stress concentration phenomenon is obvious, and connecting panel is more, and rigidity is large, large to the deformation constrain of Spherical Tank Shell Plates, worsens the state of stress in this region; Pillar turnup structure Area of bearing is little, and stress intensity is high.
Another kind of supporting way adopts skirt to support, and this is the technology that a kind of there be limited evidence currently of uses, but the prior art structure of which is simple, only adopts a cylinder directly to weld with spherical shell, spherical shell has 2 large door-shaped passages and one group of loop hole.The major defect of prior art is: cylinder and spherical shell are fillet weld, weldquality not easily ensures, and in weld seam, there is larger shearing stress, connection structure easily lost efficacy, more obvious shortcoming is, during spherical tank whole body heat treatment, skirt cylindrical shell be heated from spherical shell and temperature traverse different, skirt cylindrical shell and spherical shell can not realize synchronous thermal walking (expand and shrink), make to there is very large thermal (temperature difference) stress between skirt cylindrical shell and spherical shell, due to this rigid construction of pure cylinder skirt, not easily discharge thermal (temperature difference) stress, easily crack or lost efficacy.On the other hand, for the Spherical Tank mouth of pipe and pipeline are drawn skirt, existing skirt cylindrical shell opens large-scale door-shaped passage, serious to the weakening of skirt, causes Skirt structure to depart from cylindrical structure in computation model, there is security risk.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned defect overcoming known technology existence, and a kind of spherical tank is provided, effectively can avoid shore supports spherical tank discontinuity, weld the problem of not easily ensuring the quality of products, can solve again that existing skirt support technology heat treatment thermal (temperature difference) stress not easily discharges, skirt weakens serious weakness.
