Description

Technical Field

[0001] This utility model relates to the field of pressure vessel technology, and in particular to a bowl-shaped flange structure for a tank body. Background Technology

[0002] Pressure vessels are generally defined as containers with a working pressure greater than or equal to 0.1 MPa, a volume greater than or equal to 0.03 m³, and an inner diameter greater than or equal to 150 mm. They can hold gases, liquefied gases, and liquids whose maximum operating temperature is higher than or equal to their standard boiling point.

[0003] Chinese patent CN106531238B discloses a double-layered main pump pressure vessel, comprising an outer cylinder assembly, an upper flange welded to the upper end of the outer cylinder assembly, a lower end cap assembly welded to the bottom of the outer cylinder assembly, and an inner sleeve assembly. An annular cavity is formed between the outer cylinder assembly and the inner sleeve assembly. The inner sleeve assembly is located inside the outer cylinder assembly and includes an upper inner sleeve assembly and a lower inner sleeve assembly. An upper connecting pipe on the upper inner sleeve assembly and a lower connecting pipe on the lower inner sleeve assembly are connected by an embedded fit. The upper connecting pipe can be replaced by a wedge check valve. Multiple inner sleeve pressure taps are also provided at the upper end of the lower connecting pipe, and the bottom of the lower connecting pipe is connected to the lower end cap assembly by an embedded fit. An outer sleeve pressure tap is also provided at the upper end of the outer cylinder assembly. This invention, through the above structure, overcomes the shortcomings of existing pressure vessels with their distributed layout occupying space and lacking corresponding measuring points for main pump and wedge check valve pressure measurement.

[0004] However, this technical solution involves the feed inlet being directly connected to the outer cylinder before the material is fed into the inner cylinder. This process may result in uneven stress on the material, which could damage the cylinder structure. Furthermore, feeding the material into the outer cylinder first may lead to leakage. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a can body bowl-shaped flange structure. By using an outer cone set between the inner liner and the outer casing, combined with an assembly component fixedly connected to the inner liner within the outer cone, the function of directly feeding materials into the inner liner is achieved, thus solving the problem of structural damage caused by uneven material stress in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A can body with a bowl-shaped flange structure includes: an inner liner and an outer casing disposed on the outer periphery of the inner liner, and further includes: an outer cone disposed between the inner liner and the outer casing, wherein an assembly component fixedly connected to the inner liner is disposed within the outer cone.

[0008] Preferably, an arc-shaped structure is provided between the outer cone and the outer cylinder.

[0009] Preferably, the arc-shaped structure includes: a bent portion disposed at one end of the outer casing, a first straight edge disposed at the end of the bent portion, and a second straight edge disposed at one end of the outer casing cone, wherein the first straight edge and the second straight edge are welded together.

[0010] Preferably, the outer cylindrical body and the bent portion are formed by bending.

[0011] Preferably, one end of the outer cone is fixedly connected to the outer cylinder, and the other end is fixedly connected to the outer surface of the inner cylinder.

[0012] Preferably, the outer cone has an opening formed inside, and the opening expands sequentially from the inner liner to the outer liner.

[0013] Preferably, the assembly component is disposed within the opening.

[0014] Preferably, the assembly component is connected to the inner cavity of the inner liner.

[0015] Preferably, the size of the opening is adapted to the size of the assembly component.

[0016] Preferably, an outer cavity is formed between the outer casing and the inner casing, and the outer cone seals the outer cavity.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) This utility model divides the tank into a double-layer structure. The inner and outer layers provide additional protection. Even if the inner layer leaks, the outer layer can prevent the leaked material from escaping, thereby avoiding harm to the environment and personnel and significantly improving the safety of the tank. The double-layer structure has strong adaptability and can extend the service life of the tank. Moreover, the assembly parts are directly connected to the inner cylinder, ensuring that the material is subjected to uniform force, without damaging the tank, and without affecting the installation and use of the outer cylinder. This simplifies the structure of the entire tank and reduces the cost of use.

[0019] (2) This utility model is formed by welding the first bent part at one end of the outer cylindrical body to the second bent part at one end of the outer cone. At this time, both the first bent part and the second bent part are straight edges. Welding straight edges together is more convenient and can effectively avoid direct sharp contact before welding, thus improving the quality of welding. This makes the connection between the outer cylindrical body and the outer cone more stable and firm, thereby ensuring the sealing of the outer cavity and preventing leakage. After welding, only the welding excess height needs to be removed and the surface part needs to be simply treated. No secondary welding is required, which reduces unnecessary operations and lowers costs.

[0020] (3) The present invention is formed by bending the outer cylindrical body and the first bending part, and the outer cone and the second bending part. The bending forming is the same as the integral forming. Because the integral forming can complete the forming process of the outer cylindrical body and the outer cone in one go, the production time is greatly shortened, the production efficiency is improved, the cost is low, and the production links are reduced. The quality of the outer cylindrical body and the outer cone can be better controlled, and their production accuracy and repeatability can be improved, thereby ensuring that the size and quality of each outer cylindrical body and the outer cone are consistent, which is suitable for mass production.

[0021] In summary, this utility model has the advantages of good sealing performance, no leakage, long service life, low cost, simple structure and easy assembly and disassembly. Attached Figure Description

[0027] Example

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a can body with a bowl-shaped flange structure, including: an inner liner 1 and an outer casing 2 disposed on the outer periphery of the inner liner 1, and further including: an outer casing cone 3 disposed between the inner liner 1 and the outer casing 2. The outer casing cone 3 is provided with an assembly component 4 fixedly connected to the inner liner 1. That is, the can body has a double-layer structure, with the inner and outer layers providing additional protection. Even if the inner layer leaks, the outer layer can prevent the leaked material from escaping, thereby avoiding harm to the environment and personnel, significantly improving the safety of the can body. The double-layer structure has strong adaptability and can extend the service life of the can body. Moreover, the assembly component 4 is directly connected to the inner liner 1 without affecting the installation and use of the outer casing 2, simplifying the structure of the entire can body and reducing the cost of use.

[0029] An arc-shaped structure 5 is provided between the outer cone 3 and the outer cylinder 2. The arc-shaped structure 5 includes: a bent portion 21 at one end of the outer cylinder 2, a first straight edge 23 at the end of the bent portion 21, and a second straight edge 31 at one end of the outer cone 3. The first straight edge 23 and the second straight edge 31 are welded together. Welding straight edges together is more convenient and can effectively avoid direct sharp contact during welding, thus improving the welding quality. This makes the connection between the outer cylinder 2 and the outer cone 3 more stable and firm. After welding, only the welding excess height needs to be removed and the surface needs to be simply treated. No secondary welding is required, reducing unnecessary operations and lowering costs.

[0030] Meanwhile, the welding position is located on the side of the outer cone 3, rather than at the corner where the outer cone 3 meets the outer cylinder 2. Welding on the outer cone 3 makes the welded structure more robust, extends its service life, and is also easier to operate.

[0031] In this embodiment, the outer cylindrical body 2 and the bending portion 21 are formed by bending, which is also known as integral forming. Integral forming can complete the forming process of the outer cylindrical body 2 and the outer cone 3 in one go, which greatly shortens the production time, improves the production efficiency, reduces the cost, and reduces the production steps. It can also better control the quality of the outer cylindrical body 2 and the outer cone 3, improve their production accuracy and repeatability, thereby ensuring that the size and quality of each outer cylindrical body 2 and the outer cone 3 are consistent, which is suitable for mass production.

[0032] In this embodiment, one end of the outer cone 3 is fixedly connected to the outer cylinder 2, and the other end is fixedly connected to the outer surface of the inner cylinder 1. Both are welded, which can ensure sealing and prevent material leakage, and also make the overall structure of the tank more stable and solid.

[0033] In this embodiment, the outer cone 3 has an opening 32 formed inside. The opening 32 expands sequentially from the inner cylinder 1 to the outer cylinder 2. The assembly component 4 is provided inside the opening 32, which can ensure the smooth installation and disassembly of the assembly component 4. It is simple to operate and convenient to use.

[0034] In this embodiment, the assembly component 4 is connected to the inner cavity 11 inside the inner cylinder 1, thereby ensuring that when the assembly component 4 is connected to external parts, the parts can be directly connected to the inner cavity 11. Its structure is simple and easy to use.

[0035] Of course, the size of the opening 32 is adapted to the size of the assembly component 4, and preferably the size of the opening 32 needs to be larger than the size of the assembly component 4, so that the assembly component 4 can be installed and disassembled smoothly.

[0036] In addition, an outer cavity 22 is formed between the outer casing 2 and the inner casing 1. The outer cone 3 seals the outer cavity 22, and the outer cone 3 and the inner casing 1 are also welded together. This ensures the sealing of the entire outer cavity 22 and makes the connection between the inner casing 1, the outer casing 2, and the outer cone 3 more stable and secure, thereby extending the service life of the tank.

[0037] The working process of this embodiment is as follows: First, the blanking size of the outer casing 2 is determined according to the parameters of the straight edge bending machine. After the blanking size is determined, the blanking is then done. After the blanking is completed, the inner casing 1 and the outer casing 2 are bent into circles on the bending machine. After the outer casing 2 is bent into circles, it is placed on the straight edge bending machine to bend the first straight edge 23. After the inner casing 1 and the outer casing 2 are made, the outer casing cone 3 is bent into shape according to the forming size. The outer casing cone 3 is spliced ​​with the outer casing 2, with straight edges aligned, and finally welded into shape.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
