All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0037] Example 1

[0038] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,This embodiment proposes a novel embedded pressure vessel lifting structure, including a pressure vessel 1;

[0039] The pressure vessel 1 comprises a cylinder 2, a top end of which is provided with a container cover 3, which is sealably fixedly connected to the top end of the cylinder 2 along the axial direction of the cylinder 2;

[0040] The bottom end of the cylinder 2 is provided with a container bottom plate (not shown in the figure), and the container bottom plate is sealably fixedly connected to the bottom end of the cylinder 2 along the axial direction of the cylinder 2;

[0041] A plurality of through holes 4 are symmetrically opened at the center of gravity of the container cover 3. Lifting blocks 5 are fixedly connected to the interior of the plurality of through holes 4. The top surface of the lifting blocks 5 is located at the same horizontal plane as the top surface of the container cover 3.

[0042] A screw hole 6 is formed at the axis of the lifting block 5 , and an inner wall of the screw hole 6 has an internal thread.

[0043] When in use, first, the staff screws the screws on the sling into the screw holes 6 of the lifting block 5 so that the screws fit tightly with the internal threads in the screw holes 6. Since the lifting block 5 is welded in the through hole 4 of the container cover 3, and the cylinder 2, the container cover 3 and the container bottom plate are welded into one, when the lifting block 5 is lifted, the pressure vessel 1 is lifted. Moreover, the top surface of the lifting block 5 and the top surface of the container cover 3 are on the same horizontal plane, so the pressure vessel 1 can be stacked and stored.

[0044] The novel embedded pressure vessel lifting structure disclosed in this embodiment has the top surface of the lifting block 5 and the top surface of the container cover 3 located on the same horizontal plane, so the pressure vessel 1 can be stacked and stored. The setting of the lifting block 5 facilitates the lifting of the pressure vessel 1, thereby making the novel embedded pressure vessel lifting structure have the beneficial effects of simple structure, easy lifting of the pressure vessel 1, easy stacking installation / transportation and high lifting safety.

[0045] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 Several through holes 4 are provided with V-shaped openings 7 in the circumferential direction at one end near the outer side surface of the container cover 3. The setting of the V-shaped openings 7 facilitates increasing the welding area between the lifting block 5 and the container cover 3, which is beneficial to improving the strength of the welding between the lifting block 5 and the container cover 3, and thus is beneficial to lifting the pressure vessel 1.

[0046] The lifting block 5 is welded in the through hole 4 of the container cover 3. Only by welding can the lifting block 5 and the container cover 3 be integrated into a whole to the greatest extent, thereby ensuring the strength of the connection between the lifting block 5 and the container cover 3.

[0047] The end of the lifting block 5 away from the container cover 3 is located inside the cylinder 2, and the end of the lifting block 5 away from the container cover 3 is radially fixedly connected to a plurality of reinforcement members 8, and the top surfaces of the plurality of reinforcement members 8 are fixedly connected to the inner top surface of the container cover 3. The plurality of reinforcement members 8 can effectively enhance the rigidity and safety of the lifting block 5, thereby preventing the lifting block 5 from being separated from the pressure vessel 1 due to the pressure vessel 1 being too heavy, thereby improving the safety during the lifting process.

[0048] The plurality of reinforcement members 8 are evenly distributed along the circumferential direction of the lifting block 5 , which is beneficial for distributing the force on the pressure vessel 1 and preventing the pressure vessel 1 from being damaged.

[0049] The interior of the cylinder 2 has a volume cavity 9, which is located inside the pressure vessel 1. The volume cavity 9 can accommodate substances, making it easy to ship and store the substances.

[0050] A number of holes 10 are provided on the side wall of the cylinder 2, and a sleeve 11 is provided at one end of the holes 10 close to the volume chamber 9. One end of the sleeve 11 is a sealed connection, and the other end of the sleeve 11 can be sealed and fixedly connected in the hole 10. The hole 10 is sealed by the sleeve 11. When the staff needs to measure the internal data of the volume chamber 9 through the instrument, they only need to insert the instrument into the hole 10 to measure the corresponding data of the substance inside the volume chamber 9.

[0051] The pressure vessel 1 has a rectangular structure. The stacking effect can be achieved by configuring the pressure vessel 1 as a rectangular body, which is beneficial for transportation and storage and greatly saves storage space.

[0052] The outer corners of the pressure vessel 1 are all arc angles 12. By setting the outer corners of the pressure vessel 1 to the arc angles 12, the pressure vessel 1 can avoid damaging surrounding people or objects during the lifting process, effectively reducing the transportation risk.

[0053] In this embodiment, the diameter of the through hole 4 is slightly larger than the diameter of the lifting block 5 to facilitate welding. At the same time, when there are several through holes 4, the centers of several through holes 4 coincide with or are close to the center of gravity of the pressure vessel 1.

[0054] In this embodiment, after the lifting block 5 is welded to the container cover 3, the weld needs to be polished until it is flush with the base material, and the weld needs to be subjected to 100% layer-by-layer liquid penetration / magnetic particle inspection to ensure the integrity of the pressure boundary.

[0055] In this embodiment, the welding height of the plurality of reinforcements 8 is determined according to the thinner wall thickness of the two welded parts, and is not less than 70% of the thinner wall thickness. The width and thickness of the reinforcement are determined according to the weight to be lifted.

[0056] In this embodiment, the embedded lifting structure will not affect the external dimensions of the equipment and is suitable for pressure vessels 1 with external dimension control requirements or that need to be stacked; the embedded lifting structure is simple and easy to process, and is convenient for lifting and installation implementation; the addition of reinforcement 8 ensures the safety of lifting; through welding and inspection methods, the equipment lifting is achieved and the integrity of the pressure boundary is ensured; the embedded lifting structure can be extended and applied to any type of lifted equipment, and it is only necessary to control the upper end face of the lifting block 5 to be consistent with the upper end face structure of the equipment.

[0057] Example 2

[0058] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 On the basis of the first embodiment, a lifting block 5 can be provided at the center of gravity of the container cover 3 of the pressure vessel 1, which is suitable for the case where the weight of the pressure vessel 1 is not very large, thereby improving the efficiency of lifting the pressure vessel 1.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
