Description

Technical Field

[0002] Mobile tanks, such as mobile pressure vessels, are mainly used to store and transport various types of gas, liquid or solid materials. They are flexible and can be easily adjusted to suit different work requirements. At the same time, mobile tanks can also be combined or separated for easy transportation and operation.

[0003] The tank body of the existing mobile pressure vessel is generally made of a single material such as carbon steel or stainless steel.

[0004] However, although carbon steel has high strength, tanks made of carbon steel are prone to rust and stress corrosion, which affects the service life of the tank. The overall strength of tanks made of stainless steel is lower than that of carbon steel tanks. When using stainless steel tanks to transport pressurized media, in order to ensure the safety of the tank, the tank needs to have a larger wall thickness, resulting in a heavier overall mass of the tank, which is not conducive to the lightweight requirements of mobile pressure vessels. At the same time, due to the total weight restrictions of regulations, the volume of stainless steel tanks is limited, thereby limiting the scope of application of stainless steel tanks.

DETAILED DESCRIPTION

[0031] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0032] In the description of the present invention, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] The tank bodies of existing mobile pressure vessels are generally made of a single material such as carbon steel or stainless steel. However, although carbon steel has high strength, tank bodies made of carbon steel are prone to rust and stress corrosion, which affects the service life of the tank body. The overall strength of a tank body made of stainless steel is lower than that of a carbon steel tank body. When a stainless steel tank body is used to transport pressurized media, in order to ensure the safety of the tank body, the tank body needs to have a larger wall thickness, resulting in a heavier overall mass of the tank body, which is not conducive to the lightweight requirements of mobile pressure vessels. At the same time, due to the restrictions on the total weight of regulations, the volume of a stainless steel tank body is limited, thereby limiting the scope of application of the stainless steel tank body. Therefore, a mobile pressure vessel is proposed to solve the above problems.

[0035] The scheme is further illustrated by the following examples:

[0036] Figure 1It is a cross-sectional schematic diagram of a mobile pressure vessel according to an embodiment of the utility model. Figure 2 yes Figure 1 A magnified view of point A. Figure 3 yes Figure 1 Another cross-sectional schematic diagram of a mobile pressure vessel. Figure 4 yes Figure 1 A partial schematic diagram of the cylinder of a mobile pressure vessel.

[0037] See also Figure 1 The mobile pressure vessel of this embodiment can be configured as a cryogenic storage tank for storing cryogenic liquid or gaseous media, such as liquefied natural gas, liquefied gasoline, etc.

[0038] In some other embodiments, the mobile pressure container can also be used to transport or store liquids at room temperature, such as liquid food or chemical products.

[0039] See also Figure 1 The mobile pressure vessel comprises a cylinder 10, a wave-proof assembly 20 and two heads 40. The two heads 40 are respectively connected to the two ends of the cylinder 10 in the axial direction, and the wave-proof assembly 20 is installed inside the cylinder 10 so that the wave-proof assembly 20 can reduce the fluctuation and impact of the medium in the pressure vessel.

[0040] See also Figure 2 and Figure 4 The cylinder 10 may be provided with a coating 11 and a base layer 12. The coating 11 may be provided as a stainless steel layer, the base layer 12 may be provided as a carbon steel layer, and the base layer 12 may be wrapped around the outside of the coating 11 so that the base layer 12 may be completely wrapped around the outside of the coating 11.

[0041] It should be noted that the strength of carbon steel is higher than that of stainless steel. The base layer 12 made of carbon steel can ensure the structural strength of the cylinder 10 itself and ensure that the structural strength of the pressure vessel meets the industry standards. In addition, the cost of carbon steel is lower than that of stainless steel. Under the premise of ensuring the same structural strength, the base layer 12 made of carbon steel can reduce the manufacturing cost of the cylinder 10.

[0042] At the same time, the corrosion resistance of stainless steel is higher than that of carbon steel. Therefore, the coating 11 made of stainless steel is used so that the coating 11 is in direct contact with the medium and can isolate the medium from the base layer 12 made of carbon steel, thereby avoiding stress corrosion cracking of the pressure vessel when the carbon steel material contacts the medium, thereby improving the service life of the pressure vessel.

[0043] Therefore, the cylinder 10 composed of the stainless steel coating 11 and the carbon steel base 12 can take into account the structural strength and corrosion resistance of the pressure vessel, the volume and lightness of the pressure vessel, and reduce the manufacturing cost of the pressure vessel.

[0044] See also Figure 4 The thickness of the base layer 12 may be greater than the thickness of the coating layer 11. Since the base layer 12 is a carbon steel layer, increasing the thickness of the base layer 12 can both enhance the structural strength of the cylinder 10 and reduce the manufacturing cost of the cylinder 10.

[0045] In some other embodiments, the thickness of the base layer 12 can be set to be the same as the thickness of the cover layer 11.

[0046] In this embodiment, during the actual production process of the pressure vessel, the coating 11 and the base layer 12 can be first pressed together to form a composite plate material having a coating 11 of stainless steel material and a base layer 12 of carbon steel material, and then the composite plate material is made into a cylinder 10 according to a predetermined shape.

[0047] It should be noted that the cylinder body 10 can be welded together by a plurality of cylinder segments, and the cylinder segments are also made of a coating 11 and a base layer 12. When a plurality of cylinder segments are welded together, the coatings 11 of different cylinder segments are welded correspondingly, and the base layers 12 of different cylinder segments are welded correspondingly, so that the plurality of cylinder segments can be welded together into the cylinder body 10. In addition, when welding different cylinder segments, the coatings 11 between different cylinder segments are connected by a welding layer of stainless steel material, and the base layers 12 between different cylinder segments are connected by a welding layer of carbon steel material, so as to ensure the stability of the connection between different cylinder segments.

[0048] Figure 5 yes Figure 1 A partial schematic diagram of the wave-proof components of a mobile pressure vessel. Figure 6 yes Figure 1 Schematic diagram of the pad of a mobile pressure vessel.

[0049] See also Figure 3 and Figure 5 The wave-proof component 20 can be arranged in the cylinder 10. The wave-proof component 20 can include a pad 21 and a wave-proof plate 22.

[0050] The side of the pad 21 facing the outside of the cylinder 10 can be attached to the inner wall of the base layer 12 , that is, the pad 21 is directly connected to the base layer 12 to enhance the connection strength between the pad 21 and the base layer 12 .

[0051] It should be noted that, since the cylinder 10 is composed of a coating 11 and a base layer 12, and the wave-breaking assembly 20 is subjected to the axial impact force of the liquid medium in the cylinder 10, the pad 21 is connected to the base layer 12 to ensure the connection strength between the wave-breaking assembly 20 and the cylinder 10, and to ensure the structural strength of the wave-breaking assembly 20. In addition, if the pad 21 is connected to the coating 11, when the wave-breaking assembly 20 is subjected to an axial impact force, the coating 11 will not be able to withstand the axial force, which may easily cause cracks or bulges at the connection between the coating 11 and the pad 21, thereby affecting the use of the cylinder 10. Therefore, in this embodiment, the pad 21 needs to be directly connected to the base layer 12 to ensure the connection strength between the wave-breaking assembly 20 and the cylinder 10.

[0052] An avoidance hole 111 may be opened on the cover 11 corresponding to the pad 21 , so that the side of the pad 21 facing the inside of the cylinder 10 can be inserted into the avoidance hole 111 and extend into the inside of the cylinder 10 .

[0053] The wave-breaking plate 22 is connected to the side of the pad 21 facing the inside of the cylinder 10, so that the wave-breaking plate 22 can lie across the cylinder 10 to reduce the fluctuation and impact of the medium in the pressure vessel and ensure the safety of the medium during transportation.

[0054] In this embodiment, both the backing plate 21 and the wave-breaking plate 22 can be set as carbon steel plates, so that the connection strength between the backing plate 21 and the base layer 12 meets the requirements.

[0055] Of course, in some other embodiments, the pad 21 and the wave-breaking plate 22 may also be made of stainless steel plates to improve the corrosion resistance of the wave-breaking component 20.

[0056] See also Figure 6 , a plug welding through hole 211 may be provided on the backing plate 21, and the axial direction of the plug welding through hole 211 may extend along the radial direction of the cylinder 10. The backing plate 21 is fixed to the inner wall of the base layer 12 by a welding structure, and the welding structure is located in the plug welding through hole 211. That is, when the backing plate 21 is welded to the base layer 12, the welding spot is surfacing in the plug welding through hole 211 to enhance the connection strength between the backing plate 21 and the base layer 12, and improve the connection stability between the backing plate 21 and the base layer 12.

[0057] See also Figure 5 The mobile pressure vessel may further include a cladding layer 31. The cladding layer 31 is arranged in the avoidance hole 111 to fill between the backing plate 21 and the cladding layer 11 and cover the base layer 12 in the avoidance hole 111, thereby ensuring the connection stability between the backing plate 21, the base layer 12 and the cladding layer 11, and preventing the medium in the cylinder 10 from contacting the base layer 12 through the avoidance hole 111, thereby preventing the medium from corroding the base layer 12.

[0058] It should be noted that the cladding layer 31 is a structure formed by a stainless steel cladding layer 31, so that the cladding layer 31 is prevented from being corroded by the medium when it contacts the medium in the cylinder 10. In addition, after the cladding layer 31 is welded in the avoidance hole 111, the inner wall of the cladding layer 31 needs to be polished to ensure that the inner wall of the cladding layer 31 remains flat, thereby increasing the weld area of ​​the cladding layer 31, increasing the welding strength, and preventing the cladding layer 11 from being torn when the medium fluctuates in the tank.

[0059] See also Figure 3 and Figure 5 A connecting portion 212 may be protruded from one side of the pad 21 facing the center of the cylinder 10 , and the wave-breaking plate 22 is fixedly connected to the pad 21 via the connecting portion 212 .

[0060] In this embodiment, the connection portion 212 and the wave-breaking plate 22 can be connected by connecting bolts. Of course, in some other embodiments, the connection portion 212 and the wave-breaking plate 22 can also be welded or riveted to connect the wave-breaking plate 22 and the pad 21.

[0061] See also Figure 3 The shape of the connecting portion 212 can be set to an arc or fan shape that matches the inner wall of the cylinder 10, so that the connecting portion 212 can be connected to the wave-breaking plate 22 and the wave-breaking plate 22 can lie across the cylinder 10.

[0062] Meanwhile, a plurality of the backing plates 21 and the connecting portions 212 are provided, and the backing plates 21 and the connecting portions 212 correspond to each other one by one, and the plurality of backing plates 21 and the connecting portions 212 are arranged on the inner wall of the cylinder 10 along the circumferential direction.

[0063] In this embodiment, a plurality of wave-breaking plates 22 may be provided. The plurality of wave-breaking plates 22 are all connected to the connecting portion 212 of the pad 21, and the plurality of wave-breaking plates 22 are arranged at intervals along a certain radial direction, so that the wave-breaking plates 22 can cut and buffer the flow of the liquid medium in the cylinder 10, thereby reducing the harm of the fluctuation of the liquid medium to the container.

[0064] See also Figure 5 A reinforcing portion 213 is further provided between the connecting portion 212 and the pad 21 to enhance the connection strength between the connecting portion 212 and the pad 21. The reinforcing portion 213 may be provided as a welding layer, or may be provided integrally with the pad 21 and the connecting portion 212.

[0065] It should be noted that, in actual use, the reinforcing portion 213 needs to be concavely polished to achieve a smooth transition between the pad 21 and the connecting portion 212, thereby ensuring the safety of the pad 21 and the connecting portion 212 during use.

[0066] See also Figure 1There are multiple wave-proof components 20, and the multiple wave-proof components 20 are axially spaced apart in the cylinder 10, so as to reduce the impact of the liquid medium in the cylinder 10 on the cylinder 10 itself, thereby ensuring the safe use of the cylinder 10.

[0067] See also Figure 1 The mobile pressure vessel may further include two end caps 40 , wherein the two end caps 40 are connected to the two ends of the cylinder 10 in the axial direction, respectively.

[0068] See also Figure 2 The sealing head 40 may include an inner layer 41 and an outer layer 42. The inner layer 41 is a stainless steel layer; the outer layer 42 is a carbon steel layer, and the outer layer 42 is wrapped on the outer side of the inner layer 41.

[0069] It should be noted that when the head 40 is installed on the cylinder 10, the inner layer 41 is welded to the covering layer 11, and the outer layer 42 is welded to the base layer 12, so as to ensure that the stainless steel layer and the carbon steel layer between the cylinder 10 and the head 40 can be welded accordingly, thereby ensuring the connection stability between the head 40 and the cylinder 10.

[0070] See also Figure 1 The mobile pressure vessel may further include a flange 51. The flange 51 may be provided on the cylinder 10 to connect the inside and outside of the cylinder 10. A plurality of flanges 51 may be provided, and the flange 51 may be provided as an injection port or an outlet to inject or discharge a medium.

[0071] It should be noted that when the flange 51 has a large diameter, the flange 51 can be made of forged carbon steel and welded with stainless steel to save the manufacturing cost of the flange 51 and take into account the anti-corrosion ability of the flange 51. When the flange 51 has a small diameter, the support seat 52 can be forged with stainless steel to take into account the structural strength and corrosion resistance of the flange 51.

[0072] See also Figure 1 The mobile pressure container may further include a support seat 52. The support seat 52 may be fixed on the base layer 12 and located at the bottom of the cylinder 10 to support the pressure container.

[0073] In this embodiment, the support seat 52 can be connected to the walking mechanism so that the pressure vessel can move with the walking mechanism. At the same time, the support seat 52 can be set as a carbon steel support seat to support the pressure vessel.

[0074] Of course, in some other embodiments, the support seat 52 may also be configured to be other metal materials to ensure the structural strength of the support seat 52 .

[0075] In this embodiment, the mobile pressure vessel may further include a traction seat 53. The traction seat 53 may be installed at the bottom of the cylinder 10, located at the axial end of the cylinder 10, and spaced apart from the support seat 52. The traction seat 53 may be connected to a traction head, so that the traction head can drive and drive the pressure vessel to move.

[0076] In addition, the traction seat 53 can be configured as a carbon steel traction seat made of carbon steel material, so that the traction seat 53 can have sufficient structural strength to support and tow the pressure vessel. At the same time, the traction seat 53 made of carbon steel material can be directly welded to the base layer 12 made of carbon steel material, thereby ensuring the connection strength between the traction seat 53 and the base layer 12.

[0077] In summary, the cylinder 10 includes a coating 11 and a base layer 12, and the pad 21 of the wave-proof assembly 20 is connected to the base layer 12, which can take into account the anti-corrosion performance of the cylinder 10 while improving the structural strength of the cylinder 10 and reducing the manufacturing cost of the cylinder 10. At the same time, since the pad 21 is connected to the base layer 12, the connection strength between the base layer 12 and the pad 21 can be guaranteed, and the construction strength and use safety of the wave-proof assembly 20 can be guaranteed.
