[0014] In some embodiments, the first surface and the spherical tank body are welded together by a double-sided full penetration weld.

[0015] The weld seam between the first surface and the spherical tank body is ground and rounded.

[0016] And / or, non-destructive testing is performed on the surface of the weld between the first surface and the spherical tank body.

[0017] In some embodiments, the first support assembly comprises a plurality of first support members, the plurality of first support members are arranged in sequence and spaced apart along a circumferential direction of the spherical tank body;

[0018] The second support assembly comprises a plurality of second support members, the plurality of second support members are arranged one-to-one corresponding to the plurality of first support members;

[0019] The plurality of struts are arranged one-to-one corresponding to the plurality of second support members;

[0020] The plurality of reinforcing members are arranged one-to-one corresponding to the plurality of struts.

[0021] In some embodiments, along a height direction of the spherical tank body, the plurality of first support members are at the same height as the welding position of the outer peripheral wall of the spherical tank body.

[0022] In some embodiments, the second support assembly comprises a first connecting segment and a second connecting segment connected in sequence, the first connecting segment is welded to the second surface, and the second connecting segment is welded to the second surface and the strut respectively.

[0023] In some embodiments, the strut has a first mounting end and a second mounting end, along the height direction of the spherical tank body, the first mounting end is arranged above the second mounting end in sequence and spaced apart, and the plurality of struts are arranged in sequence and spaced apart along the circumferential direction of the spherical tank body.

[0024] The spherical tank structure further comprises:

[0025] The first connecting member is connected to the first mounting end of the first strut at one end, and connected to the second mounting end of the second strut at the other end;

[0026] The second connecting member is connected to the second mounting end of the first strut at one end, and connected to the first mounting end of the second strut at the other end;

[0027] The first connecting member and the second connecting member are arranged in sequence and spaced apart;

[0028] Alternatively, the first connecting member and the second connecting member are hingedly connected.

[0029] In some embodiments, the strut has two first mounting ends, the two first mounting ends are arranged in sequence and spaced apart along the height direction intersecting the spherical tank body;

[0030] The strut has two second mounting ends, the two second mounting ends are arranged in sequence and spaced apart along the height direction intersecting the spherical tank body.

[0031] In some embodiments, the strut comprises:

[0032] The outriggers are connected to the second surface and the second support assembly, respectively.

[0041] This spherical tank structure, by incorporating a first support component and ensuring its first surface is in close contact with the outer peripheral wall of the tank body, reduces abrupt geometric changes between the two. The first surface also forms a reinforcing surface on the outer peripheral wall of the tank body. Furthermore, the first support component can form a ring-shaped reinforcing structure on the outer peripheral wall of the tank body, allowing the pressure or stress of the tank body to be distributed over a larger area, thereby reducing stress concentration between the tank body and the first support component. By incorporating a second support component and welding it to both the second surface and the support column, a smooth, rigid transition is achieved between the tank body and the support column, reducing stress peaks caused by sudden changes in cross-section between the tank body and the support column. In addition, compared to the traditional method of directly welding the spherical tank body and the support column using fillet welds, by setting up a first support component and a second support component, the stress originally applied to the support column can be dispersed. Furthermore, the original single high-risk weld between the spherical tank body and the support column can be broken down into welds between the first surface and the spherical tank body, between the first and second support components, between the second surface and the support column, and between the second support component and the support column. This results in multiple low-stress weld segments, reducing the superposition of residual welding stress between the spherical tank body and the support column. This improves the connection strength and stability between the spherical tank body and the support column. Adding reinforcing members further enhances the connection stability between the first support and the support column.

[0042] Therefore, the spherical tank structure provided by the embodiments of the present application can solve the problem of poor connection strength at the connection between the spherical shell and the support, which can cause the safety performance of the spherical tank to be poor.

[0055] ​In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0056] In the prior art, the spherical shell and the support column are connected by means of fillet welding.

[0057] With the change of the weight or volume of the fluid in the spherical shell, the pressure in the spherical shell will change. In this case, due to the insufficient fatigue strength of the fillet weld at the welding between the support column and the spherical shell, fatigue failure will occur at the fillet, thereby causing the connection between the spherical shell and the support column to break, thus deteriorating the safety performance of the spherical tank.

[0058] In order to overcome the defects in the prior art, by arranging the first support assembly and making the first surface of the first support assembly fit the outer peripheral wall of the spherical tank body, the geometric discontinuity between the first support assembly and the spherical tank body can be reduced. The first surface can also form a reinforcing surface for the outer peripheral wall of the spherical tank body. In addition, the first support assembly can also form an annular reinforcing structure on the outer peripheral wall of the spherical tank body, so that the pressure or stress of the spherical tank body can be dispersed to a larger area, thereby reducing the stress concentration between the spherical tank body and the first support assembly. By arranging the second support assembly and welding the second support assembly with the second surface and the support column respectively, a smooth rigid transition can be formed between the spherical tank body and the support column, and the stress peak caused by the sudden change of the cross section between the spherical tank body and the support column can be reduced. In addition, compared with the traditional method of directly welding the spherical tank body and the support column by fillet welding, by arranging the welded first support assembly and the second support assembly, the stress originally applied to the support column can be dispersed, and the original single high-risk weld between the spherical tank body and the support column can be split into the weld between the first surface and the spherical tank body, the weld between the first support assembly and the second support assembly, the weld between the second surface and the support column, and the weld between the second support assembly and the support column, thereby being split into multiple low-stress welds to reduce the superposition of the welding residual stress between the spherical tank body and the support column, thereby improving the connection strength between the spherical tank body and the support column and enhancing the connection stability between the spherical tank body and the support column. The reinforcing member can improve the connection stability between the first support and the support column.

[0059] Therefore, the spherical tank structure provided by the embodiments of the present application can solve the problem of poor connection strength at the connection between the spherical shell and the support column, and can solve the problem of poor safety performance of the spherical tank.

[0136] As shown in Figure 3 The embodiment of the application provides a machining method applied to the spherical tank structure provided by any of the above embodiments, and the machining method comprises the following steps:

[0137] S01: welding the first surface 201 of the first support assembly 200 to the outer peripheral wall of the spherical tank body 100;

[0138] S02: welding the support column 400 and the second surface 202 of the second support assembly 300;

[0139] S03: welding the second support assembly 300 and the second surface 202 and the support column 400, respectively;

[0140] S04: welding the reinforcing member 500 and the first support assembly 200 and the support column 400, respectively.

[0141] It can be understood that, through the above-mentioned embodiments, the first surface 201 of the first support assembly 200 can be connected with the outer peripheral wall of the spherical tank body 100, the generation of geometric discontinuity between the first support assembly 200 and the spherical tank body 100 can be reduced, the first support assembly 200 can further form an annular reinforcing structure, so that the stress between the first support assembly 200 and the spherical tank body 100 can be dispersed to a larger area, thereby reducing the occurrence of stress concentration between the spherical tank body 100 and the first support assembly 200, and the second support assembly 300 can be connected with the second surface 202 and the support column 400 respectively, so that a smooth rigid transition is formed between the spherical tank body 100 and the support column 400, and the formation of stress peaks caused by sudden changes in cross section between the spherical tank body 100 and the support column 400 is reduced. In addition, compared with the conventional welding of the spherical tank body 100 and the support column 400 by fillet welding, by arranging the first support assembly 200 and the second support assembly 300, the single high-risk weld between the spherical tank body 100 and the support column 400 can be divided into multiple low-stress welds, so as to reduce the superposition of welding residual stress between the spherical tank body 100 and the support column 400, thereby improving the connection strength between the spherical tank body 100 and the support column 400 and enhancing the connection stability between the spherical tank body 100 and the support column 400. By arranging the reinforcing member 500, the connection stability between the first support and the support column 400 can be improved.
