[0049] The present application provides a mobile pressure vessel for containing materials and transporting the materials.

[0050] Among them, the mobile pressure vessel is a small-capacity mobile pressure vessel, usually with a capacity of 450 L to 8500 L. The mobile pressure vessel can also be a large storage tank.

[0051] The specific embodiments of the mobile pressure vessel of the present application are described in detail below with reference to the accompanying drawings.

[0052] Figure 1 is a structural diagram of a mobile pressure vessel in this embodiment, Figure 2 for Figure 1 Cross-sectional view of the mobile pressure vessel along the AA direction.

[0053] refer to Figure 1 and Figure 2The mobile pressure vessel includes an inner container 1, an outer shell 2, an insulation layer group 3 and a support assembly. The inner container 1 is used to hold materials. The outer shell 2 is covered on the outer periphery of the inner container 1, and there is a gap between the outer shell 2 and the inner container 1. The insulation layer group 3 is provided between the inner container 1 and the outer shell 2, and is used to insulate the inner container 1. The support assembly includes a plurality of first support members 41, and the plurality of first support members 41 are distributed at intervals along the axial direction of the inner container 1. The first support member 41 is connected between the inner container 1 and the outer shell 2, and is passed through the insulation layer group 3, for supporting and reinforcing the insulation layer group 3, and for supporting the inner container 1 and the outer shell 2.

[0054] In the above-described mobile pressure vessel, the insulation group 3 and outer shell 2 are sequentially arranged around the outer periphery of the inner container 1 to enhance the thermal insulation and heat insulation of the inner container 1. This allows the mobile pressure vessel to meet the transportation requirements of certain specific hazardous goods, while maintaining high versatility. Furthermore, the outer shell 2 can, to a certain extent, prevent damage to the insulation group 3 caused by collisions or tipping of the mobile pressure vessel, thereby providing good protection for the insulation group 3. Furthermore, the provision of the outer shell 2 also provides the mobile pressure vessel with greater rigidity.

[0055] Furthermore, a plurality of first support members 41 are provided within the insulation layer group 3, thereby improving the structural reliability of the insulation layer group 3. Furthermore, since the insulation layer group 3 is connected between the inner container 1 and the outer shell 2, it can also support the outer shell 2, thereby enhancing the strength of the outer shell 2 and improving the structural stability and reliability of the mobile pressure vessel.

[0056] refer to Figure 1 、 Figure 2 The inner container 1 is hollow and is used to hold materials.

[0057] In this embodiment, the inner container 1 is made of metal.

[0058] The inner container 1 includes a cylinder 11 and end caps 12 disposed at both axial ends of the cylinder 11. The axis of the cylinder 11 extends horizontally, meaning that the inner container 1 in this embodiment is a horizontal container. In other embodiments, the axis of the cylinder 11 may also extend vertically.

[0059] The head 12 may be a dish-shaped head 12 , a spherical head 12 , an elliptical head 12 , or the like.

[0060] In this embodiment, the outer shell 2 is arranged to cover the outer periphery of the inner container 1, and there is a gap between the outer shell 2 and the inner container 1, which is used to protect the inner container 1. It can prevent the inner container 1 from being damaged due to collision or tipping of the mobile pressure container to a certain extent, thereby playing a buffering role for the inner container 1.

[0061] The housing 2 includes a main body 21 and end covers 22 disposed at two axial ends of the main body 21 .

[0062] The main body 21 is disposed around the outer periphery of the cylindrical body 11 and is spaced apart from the outer periphery of the cylindrical body 11. The axis of the main body 21 overlaps with the axis of the cylindrical body 11.

[0063] In this embodiment, the main body 21 is bent from a single plate, and the opposite ends of the plate are spliced ​​and connected to form a cylindrical structure. For example, the opposite ends of the plate can be connected and fixed by rivets, bolts, etc., or welded.

[0064] The main body 21 is sealed at the seams. Specifically, the main body 21 is provided with silicone at the seams to seal the seams.

[0065] In this embodiment, the main body 21 is made of a stainless steel plate. Specifically, the main body 21 is made of a 304 stainless steel plate.

[0066] In this embodiment, the thickness of the main body 21 is 0.6 mm to 0.8 mm, which facilitates the main body 21 to be formed by bending a stainless steel plate.

[0067] Figure 3 for Figure 1 Schematic diagram of the BB direction.

[0068] refer to Figures 1 to 3 The end cover 22 is arranged around the outer periphery of the head 12 and is spaced apart from the head 12 .

[0069] The end cap 22 includes a plurality of melon segments 221, which are circumferentially connected and fixed to the axial ends of the main body 21. Adjacent melon segments 221 are spliced ​​and fixed together. For example, the melon segments 221 and the main body 21, as well as the adjacent melon segments 221, can be fixed together by rivets, bolts, or welding.

[0070] The adjacent melon segments 221 and the melon segments 221 are sealed and connected to the main body 21. Specifically, the seams between the adjacent melon segments 221 and the connection between the melon segments 221 and the main body 21 are provided with silicone to seal the seams.

[0071] The melon segments 221 are arc-shaped, and any two adjacent melon segments 221 are spliced ​​and connected to form the basic structure of an end cap 22, the shape of which is consistent with the shape of the head 12. In this embodiment, by dividing the end cap 22 into multiple arc-shaped melon segments 221, in actual application, it is convenient to splice the multiple melon segments 221 along the circumference to the outer periphery of the head 12. Moreover, the basic structure of the end cap 22 formed by splicing multiple melon segments 221 can better fit the shape of the head 12.

[0072] In this embodiment, the melon segments 221 are formed by bending a steel plate. Specifically, the melon segments 221 are made of stainless steel plates.

[0073] The thickness of the melon segments 221 is 0.6 mm to 0.8 mm, which facilitates the bending of the stainless steel plate to form the melon segments 221 .

[0074] The end cover 22 may also include an end plate 222. The end plate 222 is attached to and connected to the outer sides of the multiple melon segments 221 away from the main body 21, covering the gaps between adjacent cover plates. Specifically, the end plate 222 may be connected to each melon segment 221 using rivets, bolts, or welding.

[0075] The end plates 222 are sealed to the melon segments 221. Specifically, silicone is provided between the end plates 222 and the melon segments 221 to seal the seams. Because the seams of the main body 21, between adjacent melon segments 221, between the melon segments 221 and the main body 21, and between the end plates 222 and the melon segments 221 are all sealed, the outer shell 2 forms a sealed structure, preventing heat exchange between its interior and the outside world. It also prevents rainwater and other substances from penetrating the interior of the outer shell 2 and exchanging heat with the inner container 1, thereby enhancing the thermal insulation effect of the inner container 1.

[0076] In this embodiment, the end plate 222 is circular, and the center of the circle is on the same straight line as the axis of the inner container 1 .

[0077] The end plate 222 is arc-shaped to adapt to the shape of the arc-shaped melon segments 221 and to facilitate fitting with the end of the structure formed by multiple melon segments 221.

[0078] In this embodiment, the end plate 222 is formed by bending a steel plate. Specifically, the end plate 222 is made of a stainless steel plate.

[0079] The thickness of the end plate 222 is 0.6 mm to 0.8 mm, which is convenient for bending the stainless steel plate.

[0080] Among them, since the main body 21, melon segments 221, and end plates 222 of the outer shell 2 are all bent from 0.6mm stainless steel, they can be well adapted to the shape of the inner container 1, and at the same time have strong rigidity and better protection effect.

[0081] In this embodiment, a drain port is further provided at the bottom of the housing 2, which is used to connect the outside with the housing 2 so that rainwater or the like that has seeped into the housing 2 can be promptly drained out when the seal at the joint of the housing 2 fails. Specifically, the drain port is provided at the bottom of the main body 21.

[0082] The number of the liquid discharge port can be one, or two or more. When there are multiple liquid discharge ports, the multiple liquid discharge ports are distributed at intervals along the axial direction at the bottom of the main body 21.

[0083] Figure 4 for Figure 3 Cross-sectional view along CC direction.

[0084] refer to Figure 2 and Figure 4 The insulation layer group 3 is provided between the inner container 1 and the outer shell 2 to insulate the inner container 1. In actual use, the insulation layer group 3 and the outer shell 2 are sequentially stacked and arranged around the outer periphery of the inner container 1. Since the shape of the outer shell 2 is consistent with that of the inner container 1, after the mobile pressure vessel is assembled, the outer shell 2 can completely fit around the outer periphery of the insulation layer group 3, thereby preventing damage to the insulation layer group 3 due to collisions or tipping of the mobile pressure vessel to a certain extent, thereby providing good protection for the insulation layer group 3. In addition, the various components of the outer shell 2 are sealed to form an enclosed space, and a drain port is provided to discharge rainwater within the outer shell 2, which can minimize the corrosion of the inner container 1 by the insulation layer group 3 in a humid environment. Since the basic structure of the end cover 22 of the outer shell is formed by multiple melon segments 221 spliced ​​together along the circumference, the basic structure of the end cover 22 formed by multiple melon segments 221 can better fit the shape of the insulation layer group 3, thereby enhancing the covering effect of the insulation layer group 3 on the outer periphery of the head 12 of the inner container 1.

[0085] In this embodiment, the thermal insulation layer group 3 is fixedly tied to the inner container 1. For example, the thermal insulation layer group 3 is fixedly tied to the inner container 1 by means of a tie, a stainless steel wire or the like.

[0086] In this embodiment, the thermal insulation layer group 3 includes a first thermal insulation layer 31. The first thermal insulation layer 31 is coated on the outer periphery of the inner container 1.

[0087] The thickness of the first thermal insulation layer 31 is 30 mm to 80 mm. For example, the thickness of the first thermal insulation layer 31 can be 60 mm ± 3 mm, so that the first thermal insulation layer 31 has a good thermal insulation effect and ensures its thermal insulation effect on the inner container 1.

[0088] The density of the first insulation layer 31 is 40 kg / m 3 ~100kg / m 3 For example, the density of the first insulation layer 31 can be 80 kg / m 3 ±8kg / m 3 , so that the first thermal insulation layer 31 has a better thermal insulation effect, thereby ensuring its thermal insulation effect on the inner container 1.

[0089] In this embodiment, the first insulation layer 31 is made of rock wool with a thermal conductivity of less than or equal to 0.044 W / mK. The rock wool is controlled in terms of organic matter content and chloride ion content according to ASTM C871 to ensure the thermal insulation effect of the second insulation layer 32.

[0090] The thermal insulation layer group 3 further includes a second thermal insulation layer 32 . The second thermal insulation layer 32 is coated on the outer periphery of the first thermal insulation layer 31 and adhered to the inner side of the outer shell 2 .

[0091] The thickness of the second insulation layer 32 is 30 mm to 80 mm. For example, the thickness of the second insulation layer 32 can be 45 mm ± 3 mm, so as to cooperate with the first insulation layer 31 and have a better insulation effect, thereby further ensuring its insulation effect on the inner container 1.

[0092] In this embodiment, the sum of the thickness of the first insulation layer 31 and the thickness of the second insulation layer 32 is greater than or equal to 105 mm, to ensure that the insulation layer group 3 formed by the first insulation layer 31 and the second insulation layer 32 has a good insulation effect, thereby ensuring that the insulation layer group 3 has an insulation effect on the inner container 1. For example, the thickness of the first insulation layer 31 can be 60 mm, and the thickness of the second insulation layer can be 45 mm.

[0093] The thickness of the first thermal insulation layer 31 and the second thermal insulation layer 32 can be determined according to actual needs and is not limited thereto.

[0094] The density of the second insulation layer 32 is 40 kg / m 3 ~60kg / m 3 For example, the density of the second insulation layer 32 may be 40 kg / m 3 ±8kg / m 3 , so that the second thermal insulation layer 32 has a better thermal insulation effect, thereby ensuring its thermal insulation effect on the inner container 1.

[0095] In this embodiment, the second insulation layer 32 is made of rock wool with a thermal conductivity of less than or equal to 0.044 W / mK. The rock wool has controlled organic matter content and chloride ion content according to ASTM C871 requirements to ensure the thermal insulation effect of the second insulation layer 32.

[0096] In this embodiment, the insulation layer group 3 adopts a double-layer structure with a stacked arrangement, that is, the insulation layer group 3 is formed by stacking a first insulation layer 31 and a second insulation layer 32, and by optimizing the thickness and density of the first insulation layer 31 and the second insulation layer 32, since the thermal conductivity of the rock wool itself is less than or equal to 0.044W / mK, at 15.5°C, it can ensure that the total thermal conductivity of the insulation layer group 3 does not exceed 1.533KJ / hrm2K, so as to meet the requirements of relevant specifications and reduce the impact of the external severe cold environment on the materials inside the container 1, so as to facilitate the safe transportation and smooth unloading of certain specific hazardous materials.

[0097] Figure 5 for Figure 2 Enlarged structural diagram at point D in the middle.

[0098] refer to Figure 2 and Figure 5 The support assembly includes a plurality of first support members 41, which are spaced apart along the axial direction of the inner container 1. The first support members 41 are connected between the inner container 1 and the outer shell 2 and pass through the thermal insulation layer group 3. They are used to support and reinforce the thermal insulation layer group 3 to improve the structural stability of the thermal insulation layer group 3. They can also be used to support the outer shell 2 to enhance the strength of the outer shell 2, thereby improving the structural stability and reliability of the mobile pressure vessel.

[0099] In this embodiment, there are two first support members 41, and the two first support members 41 are provided in a one-to-one correspondence with the two heads 12. Specifically, the first support members 41 are provided at the junction of the head 12 and the cylinder 11. That is, the first support members 41 are mainly used to support and reinforce the portion of the insulation layer group 3 located on the outer periphery of the cylinder 11, and to support and fix the main body 21 of the shell 2, and can balance the forces acting on the shell 2.

[0100] In other embodiments, when the number of the first support members 41 is more than three, two of the first support members 41 are arranged at the axial ends of the cylinder 11 close to the corresponding heads 12, and the remaining first support members 41 are randomly spaced and sleeved on the cylinder 11.

[0101] In some embodiments, when the mobile pressure vessel is a large storage tank, the number of the first support members 41 is three or more, wherein two first support members 41 are arranged at the axial ends of the cylinder 11 close to the corresponding heads 12, and the remaining first support members 41 are evenly spaced on the cylinder 11 along the axial direction of the inner container 1, and the remaining first support members 41 are located between the two first support members 41 located at the axial ends of the cylinder 11, so as to balance the support force on the outer shell 2, so that the outer shell 2 can be evenly stressed after being connected to the inner container 1 through the first support members 41, thereby improving the structural stability of the entire mobile pressure vessel.

[0102] In this embodiment, the first support member 41 includes a support ring 411, which is arranged around the outer circumference of the inner container 1 and connected between the inner container 1 and the outer shell 2. Specifically, the support ring 411 is fixed to the inner container 1 by welding.

[0103] The first support member 41 may further include a connecting tube 422, which is sleeved around the outer circumference of the support ring 411 and fixedly connected to the support ring 411. The connecting tube 422 is in contact with the inner side of the outer shell 2 and is fixedly connected to the outer shell 2. Specifically, the connecting tube 422 and the main body 21 of the outer shell 2 may be fixed by rivets, bolts, or welding, thereby ensuring that the connection between the outer shell 2 and the inner container 1 has rigid support.

[0104] In this embodiment, the axial end of the connecting tube 422 extends outwardly beyond the support ring 411, thereby increasing the contact area between the first support member 41 and the outer shell 2 and thereby enhancing the support strength of the outer shell 2. Specifically, both axial ends of the connecting tube 422 extend outwardly beyond the support ring 411. This means that the cross-section of the first support member 41 in this embodiment is T-shaped. In other embodiments, one axial end of the connecting tube 422 extends outwardly beyond the support ring 411, thus forming an L-shaped cross-section of the first support member 41.

[0105] In other embodiments, the connecting tube 422 may also be fixed to the inner circumference of the support ring 411, and be sleeved on the outer circumference of the inner container 1 and fixedly connected to the inner container 1. The outer circumference of the support ring 411 is connected to the inner side of the outer shell 2. The axial end of the connecting tube 422 extends outwardly beyond the support ring 411. Specifically, both axial ends of the connecting tube 422 extend outwardly beyond the support ring 411, that is, the cross-section of the first support member 41 is an inverted T-shape; or, one axial end of the connecting tube 422 extends outwardly beyond the support ring 411, that is, the cross-section of the first support member 41 is an inverted L-shape.

[0106] In some embodiments, the first support member 41 may also include a support ring 411 and two connecting tubes 422, with the two connecting tubes 422 being arranged radially inwardly and outwardly of the support ring 411. One connecting tube 422 is configured to be fixedly connected to the inner container 1, and the other connecting tube 422 is configured to be fixedly connected to the outer shell 2. The axial end of each connecting tube 422 extends outwardly beyond the support ring 411. Specifically, at least one axial end of each connecting tube 422 extends outwardly beyond the support ring 411. For example, the cross-section of the first support member 41 may be I-shaped, Z-shaped, or the like.

[0107] In other embodiments, the first support member 41 may only include a support ring 411 , which is sleeved on the outer periphery of the inner container 1 and welded to the inner container 1 , and the outer periphery of the support ring 411 is welded to the inner side of the outer shell 2 .

[0108] In some other embodiments, the first support member 41 may also only include a connecting tube 422, which is sleeved on the outer periphery of the inner container 1 and welded and fixed to the inner container 1. The outer periphery of the connecting tube 422 is welded and fixed to the inner side of the outer shell 2, and is connected and fixed by rivets or bolts, thereby ensuring that the connection between the outer shell 2 and the inner container 1 has rigid support.

[0109] In this embodiment, the support assembly also includes two second support members 42, which are arranged at the axial ends of the inner container 1, and are used to support and reinforce the insulation layer group 3 located on the outer periphery of the head 12, and to support and fix the end cover 22 of the outer shell 2.

[0110] Figure 6 yes Figure 2 Enlarged structural diagram at E in the middle.

[0111] refer to Figure 2 and Figure 6 The second support member 42 includes a connecting ring 421 and a plurality of connecting plates 422 .

[0112] A plurality of connecting plates 422 are circumferentially spaced apart on one side of the connecting ring 421, and one end of the connecting plate 422 facing away from the connecting ring 421 is fixedly connected to the inner container 1. Specifically, the connecting plate 422 is fixed to the inner container 1 by welding.

[0113] The connecting ring 421 is used to connect and fix with the outer shell 2. For example, the connecting ring 421 is provided with a plurality of connecting holes spaced apart along the circumference, and the end cover 22 is provided with a plurality of corresponding through holes. A rivet or bolt is passed through each connecting hole and the corresponding through hole to achieve the connection between the connecting ring 421 and the end cover 22, ensuring that the connection between the outer shell 2 and the inner container 1 has rigid support.

[0114] The center of the connecting ring 421 is located on the same straight line as the axis of the inner container 1 , so that the second support member 42 is supported on the middle part of the end cover 22 , which can balance the force on the end cover 22 .

[0115] In this embodiment, the connecting ring 421 is arc-shaped to adapt to the shape of the arc-shaped melon segments 221, and is convenient for fitting with the end of the structure formed by multiple melon segments 221, so that the second support member 42 can better support the end cover 22.

[0116] In other embodiments, the second support member 42 may also be a cylindrical integral structure. In this case, the second support member 42 is fixed to the axial end of the inner container 1 in a state where its axial direction is consistent with the axial direction of the inner container 1, and the axial outer end of the second support member 42 is connected and fixed to the end cover 22.

[0117] Figure 7 yes Figure 4 Enlarged structural diagram at F in the middle.

[0118] refer to Figure 7 In this embodiment, the support assembly also includes at least one third support member 43, which is attached to the outside of the insulation layer group 3 and fixed to the outer shell 2 to press the insulation layer group 3, thereby enhancing the structural strength of the insulation layer group 3 and strengthening the support for the outer shell 2.

[0119] Specifically, the third support member 43 is located outside the second insulation layer 32 and corresponds to the outer periphery of the cylinder 11 of the inner container 1, and is connected and fixed to the main body 21 of the outer shell 2 to strengthen the structural strength of the part of the insulation layer group 3 located on the outer periphery of the cylinder 11 of the inner container 1 and strengthen the support for the main body 21.

[0120] The third support member 43 has the same contour as the second thermal insulation layer 32 so as to fit closely with the second thermal insulation layer 32 .

[0121] For example, the third support member 43 and the outer shell 2 can be fixed by rivets or bolts, ensuring that the connection between the outer shell 2 and the inner container 1 has rigid support.

[0122] In this embodiment, the third support member 43 can be in any shape, such as a strip shape, a plate shape, or a ring shape.

[0123] In this embodiment, the first support member 41 is used to strengthen the structural strength of the portion of the insulation layer group 3 located on the outer periphery of the cylinder 11 and to support and fix the main body 21 of the outer shell 2; the second support member 42 is used to strengthen the structural strength of the portion of the insulation layer group 3 located on the outer periphery of the head 12 and to support and fix the end cover 22 of the outer shell 2; and the third support member 43 is used to further strengthen the structural strength of the portion of the insulation layer group 3 located on the outer periphery of the cylinder 11 and to support and fix the main body 21 of the outer shell 2. In other words, the first support member 41, the second support member 42, and the third support member 43 cooperate to increase the support points for the insulation layer group 3 and the outer shell 2, further improving the structural strength of the insulation layer group 3 along the circumferential direction, providing circumferential support for the outer shell 2, and thus enhancing the structural stability of the entire mobile pressure vessel.

[0124] Figure 8 2 is a top view of the mobile pressure vessel in this embodiment.

[0125] refer to Figure 1 、 Figure 2 and Figure 8 The mobile pressure vessel includes at least one structure to be installed, which is arranged on the top of the inner container 1 and protrudes out of the outer shell 2 and is exposed from the outer shell 2 to facilitate viewing and operation by staff.

[0126] In this embodiment, at least one third support member 43 is provided on the periphery of each structure to be installed, and the third support member 43 is fixedly connected to the structure to be installed. Specifically, the third support member 43 is fixed to the structure to be installed by welding.

[0127] The structure to be installed may include at least one accessory 511 .

[0128] In this embodiment, the accessory 511 can be a valve, which is provided at the top of the inner container 1 and extends into the inner container 1, and is used to control the connection and disconnection between the inner container 1 and the outside. For example, the accessory 511 can be a valve such as a relief valve, a liquid phase valve, or a gas phase valve.

[0129] The accessory 511 may also be a detection device for detecting signals inside the inner container 1. For example, the accessory 511 may be a liquid level detector for detecting liquid level signals inside the inner container 1; the accessory 511 may also be a pressure detector for detecting pressure signals inside the inner container 1; the accessory 511 may also be a temperature detector for detecting temperature signals inside the inner container 1, and so on.

[0130] When there are multiple attachments 511 , each attachment 511 has a different function.

[0131] The structure to be installed also includes an overflow box 512, which is covered on the outer periphery of the accessory 511 and fixedly connected to the top of the inner container 1. The overflow box 512 passes through the insulation layer group 3 and protrudes out of the outer shell 2, so that the overflow box 512 can separate the insulation layer group 3 from the accessory 511, thereby avoiding interference between the accessory 511 and the insulation layer group 3.

[0132] The overflow box 512 is hollow inside and has a receiving space for storing materials overflowing from the attachment 511 .

[0133] Overflow box 512 consists of a box body and a cover. The box body is connected at both ends, and the box body covers the outer periphery of accessory 511 and is welded to inner container 1. The cover is detachably connected to the top of the box body, allowing the interior of the box to be opened and closed, allowing the cover to be removed from the box body for subsequent operations on accessory 511, or to be attached to the box body to protect the accessory 511 inside.

[0134] The box body and the cover body are sealed and connected. For example, a sealing gasket is provided between the box body and the cover body to block the gap between the box body and the cover body when the cover body is connected to the box body, so as to achieve a sealed connection between the box body and the cover body.

[0135] The mobile pressure container further includes a drain pipe 6 , which is in communication with the overflow box 512 and is used for discharging the material in the overflow box 512 .

[0136] Each overflow box 512 is provided with at least one drain pipe 6. Specifically, in this embodiment, each overflow box 512 is provided with two drain pipes 6, and the two drain pipes 6 are arranged on opposite sides of the axis of the inner container 1.

[0137] In this embodiment, the drain pipe 6 comprises a first pipe section and a second pipe section. One end of the first pipe section extends through the bottom of the overflow box 512 and communicates with the interior of the overflow box 512. The other end passes through the insulation layer assembly 3 and out of the outer shell 2. The second pipe section is connected and fixed to the outer periphery of the outer shell 2. The upper end of the second pipe section communicates with the end of the first pipe section extending out of the outer shell 2. The other end extends along the circumference of the outer shell 2 to the bottom of the outer shell 2. This facilitates the discharge of materials within the overflow box 512, achieving a more effective drainage effect.

[0138] In this embodiment, the first pipe section is made of metal material. The second pipe section is made of a flexible material so as to bend and be arranged along the circumference of the housing 2. For example, the second pipe section can be made of rubber, plastic, or other materials.

[0139] The structure to be mounted can also be a base 52, which is located at the bottom of the inner container 1 and fixedly connected to the inner container 1. It is used to support the inner container 1 and serve as a load-bearing carrier for the mobile pressure vessel. The base 52 passes through the insulation layer group 3 and extends out of the outer shell 2 to facilitate contact with a supporting surface. The supporting surface here can be the ground or any other flat surface, such as a platform.

[0140] The base 52 is provided with a fork hole for cooperating with a forklift to realize the transportation of the mobile pressure container.

[0141] The structure to be mounted can also be a support base 53, which is positioned on top of the inner container 1 and fixedly connected to the inner container 1. The support base 53 passes through the insulation layer group 3 and extends out of the outer shell 2. The top of the support base 53 extends horizontally, forming the support surface described above. In actual application, the design of the support base 53 enables multiple mobile pressure vessels to be stacked. The support base 53 of the mobile pressure vessel on the lower layer abuts the base 52 of the mobile pressure vessel on the upper layer, providing a support surface for the mobile pressure vessel on the upper layer.

[0142] In this embodiment, there are multiple structures to be installed, including at least one structure formed by the combination of an accessory 511 and an overflow box 512, a base 52, and two support bases 53. The two support bases 53 are located at the axial ends of the upper portion of the inner container 1. This balances the forces acting on the upper mobile pressure vessels when the multiple mobile pressure vessels are stacked, thereby improving the overall stability of the stacked structure.

[0143] Continue to refer Figures 1 to 4 、 Figure 8The mobile pressure vessel includes a plurality of structural members, which are connected to the inner container 1 and protrude from the outer shell 2.

[0144] The structural member can be a lifting lug 71, which is fixedly connected to the top of the inner container 1. The lifting lug 71 passes through the insulation layer group 3 and extends out of the outer shell 2. The lifting lug 71 is provided with a lifting hole, which is located outside the outer shell 2. The lifting hole is used to cooperate with a lifting tool to realize the lifting and transfer of the mobile pressure vessel.

[0145] The structural member can also be a nameplate bracket, which is fixedly connected to the top of the inner container 1, passes through the insulation layer group 3 and extends out of the outer shell 2. The nameplate bracket is provided with information such as the model of the mobile pressure vessel and the load material for easy viewing by staff.

[0146] In this embodiment, the multiple structural components include four lifting lugs 71 and a nameplate bracket. The four lifting lugs 71 are distributed in an array on the inner container 1. When the lifting lugs 71 cooperate with the lifting device to lift the mobile pressure vessel, the forces acting on the mobile pressure vessel can be balanced, allowing for stable movement.

[0147] In this embodiment, at least one patch 8 is attached to the outer side of the shell 2. The patch 8 is arranged in a one-to-one correspondence with the structural member. The patch 8 is sleeved on the structural member and sealed with the structural member. The patch 8 is sealed with the shell 2. This can ensure that the shell 2 is a closed structure to avoid heat exchange between the inside of the shell 2 and the outside world. It can also prevent rainwater and other substances from penetrating into the inside of the shell 2 to exchange heat with the inner container 1, thereby enhancing the thermal insulation effect of the inner container 1.

[0148] It can be seen from the above technical solution that the present invention has at least the following advantages and positive effects:

[0149] The mobile pressure vessel of the present application enhances the thermal insulation and heat insulation of the inner container by sequentially arranging an insulation layer assembly and an outer shell around the outer periphery of the inner container. This allows the mobile pressure vessel to meet the transportation requirements of certain specific hazardous goods, while maintaining high versatility. Furthermore, the outer shell can, to a certain extent, prevent damage to the insulation layer assembly caused by collisions or tipping of the mobile pressure vessel, thereby providing good protection for the insulation layer assembly. Furthermore, the provision of the outer shell also provides the mobile pressure vessel with greater rigidity.

[0150] Furthermore, a plurality of first support members are provided within the insulation layer assembly, thereby improving the structural reliability of the insulation layer assembly. Furthermore, since the insulation layer assembly is connected between the inner container and the outer shell, it can also support the outer shell, thereby enhancing the outer shell's strength and thus improving the structural stability and reliability of the mobile pressure vessel.

[0151] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims.
