[0041] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

[0042] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0043] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0044] like Figures 1 to 3 As shown, this disclosure provides a portable container, which may include a container body 1 and a protective box 2.

[0045] The tank body 1 in this disclosure can be made of metal to ensure the overall structural strength of the tank body 1.

[0046] The top of the tank body 1 can be equipped with gas phase port, liquid phase port, spare port and safety valve port, as well as valve components 3 connected to the corresponding ports. By controlling the opening and closing of the valve components 3, the inlet and outlet of the tank body 1 (such as loading and unloading liquid) and the stability of the internal pressure can be controlled, thereby achieving safe, efficient and flexible operation of the tank body 1.

[0047] A manhole 41 may also be provided on the top of the tank 1 to allow workers to enter the tank 1 for inspection, cleaning or installation of components.

[0048] Multiple lifting lugs 42 are provided on opposite ends of the top of the tank body 1 to facilitate the lifting of the tank body 1.

[0049] For example, when the tank 1 in this disclosure is a horizontal tank, a set of lifting lugs 42 can be respectively provided at the opposite ends of the top of the tank 1 in the longitudinal Y direction. Each set of lifting lugs 42 may include two lifting lugs 42 arranged at intervals in the transverse X direction.

[0050] like Figures 4 to 5 As shown, the protective box 2 may include at least a box body, a top cover 22, and a side door 21. The box body is located on top of the tank body 1 and has a top opening. One side of the box body has a side opening. The top cover 22 is movably connected to the top of the box body to cover the top opening. The side door 21 is movably connected to the side of the box body to cover the side opening.

[0051] For example, the top cover 22 and the side door 21 can be hinged to the cabinet through a structure such as hinges, but it is not limited to this. The top cover 22 and the side door 21 can also be connected to the cabinet in other ways besides hinges, such as magnetic attraction. The specific connection can be set according to the actual situation.

[0052] The box body, top cover 22, side door 21 and tank body 1 together form an enclosure space. Valve 3 is located in the enclosure space. When the top cover 22 and side door 21 are both closed on the box body, the box body 2 can be sealed. In this way, the box body 2 can be used to isolate the valve 3 from the external environment, reduce or avoid the possibility of the valve 3 colliding with the structure in the external environment or being contaminated by water vapor, dust and other pollutants in the external environment. This can reduce the risk of product leakage inside the tank body 1, extend the service life of the valve 3, and reduce the maintenance and replacement costs of the valve 3.

[0053] In addition, the protective box 2 disclosed herein includes a top cover 22 and a side door 21 respectively disposed on the top and side of the box body, which can realize the two-way opening of the protective box 2. When the staff needs to perform operations such as opening, closing, maintenance, and replacement of the valves 3 inside the protective box 2, they can open either or both of the top cover 22 and the side door 21 according to the actual situation. While increasing the opening range of the protective box 2, it can also improve the flexibility of the opening position of the protective box 2, reduce the operational difficulty for the staff when performing corresponding operations on the valves 3 inside the protective box 2, and thus help to expand the application market of the protective box 2.

[0054] The protective box 2 can be made of 304 stainless steel to improve the structural strength of the protective box 2 and reduce the risk of corrosion from water vapor.

[0055] In some embodiments, the bottom of the side door 21 is hinged to the box body so that the side door 21 can rotate upward to block the side opening of the box body or rotate downward to expose the side opening, and the bottom of the side door 21 is spaced above the top of the tank body 1.

[0056] This embodiment of the invention increases the rotation angle of the side door 21 when it rotates downward by positioning the bottom of the side door 21 above the top of the tank body 1. This increases the exposed area of ​​the side opening of the tank body, making it easier for staff to observe the internal condition of the protective box 2. It also increases the operable space on the side of the protective box 2, allowing staff to perform operations such as opening and closing, maintenance, and replacement of the valves 3 inside the protective box 2 through the side opening.

[0057] Specifically, in this embodiment, the top of the tank 1 may be arc-shaped. In the transverse direction X, the end of the side of the box near the side door 21 is spaced apart from the tank 1, and the end of the side of the box away from the side door 21 is connected to the tank 1.

[0058] For example, tank 1 may include a cylindrical body and elliptical end caps at both ends, the cylindrical body being a hollow cylinder with open ends. Tank 1 in this disclosure may be a horizontal tank, in which case the axial direction of tank 1 extends along the longitudinal direction Y, and the two end caps are located at opposite ends of the cylindrical body along the longitudinal direction Y. However, it is not limited to this; tank 1 in this disclosure may also be a vertical tank, in which case the axial direction of tank 1 extends along the vertical direction Z.

[0059] Furthermore, the container may include two side walls 23 spaced parallel to each other along the longitudinal direction Y, and a connecting wall 24 connecting the two side walls 23. The connecting wall 24 is located at the end of the side of the container away from the side door 21, and its bottom is connected to the top of the tank 1. The ends of the side walls 23 away from the connecting wall 24 are spaced above the top of the tank 1, and the ends of the side walls 23 near the connecting wall 24 are connected to the top of the tank 1.

[0060] In this embodiment, the housing may further include a bottom plate 28 connecting the bottoms of the two side walls 23. One end of the bottom plate 28 in the horizontal direction X is connected to the top of the tank 1, and the other end of the bottom plate 28 in the horizontal direction X is spaced above the top of the tank 1 and hinged to the side door 21. The bottom plate 28 can form a seal at the bottom of the housing together with the top of the tank 1. That is, in this embodiment, by setting the bottom plate 28 in the gap between the side wall 23 and the top of the tank 1, the end of the bottom plate 28 near the side door 21 is spaced apart from the top of the tank 1, and the side of the bottom plate 28 is simultaneously connected to the top of the tank 1, the bottom of the housing, and the side door 21, so as to achieve a seal at the bottom of the housing.

[0061] In this embodiment, by spacing the bottom plate 28 near the side door 21 from the top of the tank 1, the rotation angle of the side door 21 when it rotates downward can be increased, and the exposed area of ​​the side opening of the box can be increased. This makes it easier for staff to observe the internal condition of the protective box 2 and increases the operable space on the side of the protective box 2, so that staff can perform operations such as opening and closing, maintenance, and replacement of the valves 3 inside the protective box 2 through the side opening of the box.

[0062] In addition, by setting the bottom plate 28 at a distance from the top of the tank body 1, the present embodiment can reduce or avoid friction and collision between the side door 21 and the top of the tank body 1 when the side door 21 rotates downward, thereby reducing wear on the side door 21 and the tank body 1 and extending the service life of the tank body 1 and the side door 21.

[0063] In some embodiments, one or more of the base plate 28, connecting wall 24 and side wall 23 may be provided with a bent portion that bends into the protective box 2 to enhance the sealing of the protective box 2.

[0064] For example, when the base plate 28 is provided with a bend, the bend can be connected to the inner wall of the base plate 28, and the bend can fit against the inner surface of the two side walls 23 to achieve the sealing of the protective box 2.

[0065] When the connecting wall 24 is provided with a bend, the bend can be connected to the inner surface of the connecting wall 24, and the bend can fit against the inner surface of the two side walls 23 to achieve the sealing of the protective box 2.

[0066] In some embodiments, when the side door 21 rotates to expose the side opening, the angle between the side door 21 and the housing can be in the range of 90°-120°.

[0067] For example, the angle at which the side door 21 can rotate relative to the container body can be 90°, 95°, 100°, 105°, 110°, 115°, 120°, etc., depending on the actual situation, to ensure that after the side door 21 rotates, there is sufficient space at the side opening of the container body for the operator to operate. In addition, when the bottom of the side door 21 is connected to the container body, limiting the downward rotation angle of the side door 21 can also improve the problem of friction and collision between the side door 21 and the container body 1 when rotating downwards.

[0068] In some embodiments, the side door 21 may have a door panel and a first bend, the door panel being able to cover the side opening of the housing, and the first bend being disposed on opposite sides of the door panel.

[0069] Specifically, when the bottom of the side door 21 is movably connected to the cabinet, the first bending portion is located on opposite sides of the door panel in the longitudinal Y direction. When the side door 21 is rotated upward to block the side opening of the cabinet, the door panel completely covers the side opening of the cabinet, and the first bending portion can fit against the outer surface of the cabinet. For example, when the door panel completely covers the side opening of the cabinet, the first bending portion can fit against the outer surface of the side wall 23.

[0070] This embodiment of the present disclosure improves the overall structural strength of the side door 21 by providing first bending portions on opposite sides of the door panel. The first bending portions on the door panel can also enhance the sealing of the box, reducing the problem of external moisture, dust and other impurities entering the protective box 2 through the gap between the box and the side door 21 and causing pollution and corrosion to the valve 3.

[0071] It should be noted that, in addition to making the bottom of the side door 21 movably connected to the box body, the top and sides of the side door 21 can also be movably connected to the box body in this embodiment of the present disclosure, which can be determined according to the actual situation.

[0072] In addition, the bottom of the side door 21 in this embodiment can also be directly connected to the top of the tank 1. In this case, the bottom surface of the box can be sealed by the top of the tank 1.

[0073] In some embodiments, the top cover 22 can be rotated upward to expose the top opening of the housing or rotated downward to block the top opening of the housing.

[0074] Among them, such as Figures 4 to 5 As shown, when the bottom of the side door 21 is movably connected to the box body, the side door 21 and the top cover 22 are closed on the box body. The end of the top cover 22 that is movably connected to the box body can abut against the top of the side door 21. At this time, the side door 21 and the top cover 22 are opened at the same time, and the top opening and side opening of the box body can be fully exposed.

[0075] The top opening and the side opening can be connected to each other, thus allowing a larger area of ​​the internal space of the protection box 2 to be exposed, so that staff can perform operations such as opening and closing, maintenance, and replacement of the valves 3 inside the protection box 2.

[0076] In some embodiments, when the top cover 22 is rotated to expose the top opening of the box, the angle between the top cover 22 and the top surface of the box can be in the range of 90°-130°.

[0077] For example, the angle at which the top cover 22 can rotate relative to the side wall 23 can be 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, etc. The specific angle can be determined according to the actual situation, so as to ensure that the top opening of the box can be exposed after the side door 21 is rotated for workers to operate.

[0078] In some embodiments, the top cover 22 may include a cover plate and a second bend, the cover plate being able to cover at least the top opening of the box, the second bend being connected to the cover plate, and when the top cover 22 is rotated downward to block the top opening of the box, the inner wall of the second bend near the center of the cover plate is able to face the outer surface of the box.

[0079] This embodiment of the invention, by providing a second bending portion on the cover plate, can enhance the structural strength of the top cover 22 and also improve the sealing of the box, reducing the problem of external moisture, dust and other impurities entering the interior of the protective box 2 through the gap between the box and the top cover 22 and causing pollution and corrosion to the valve 3.

[0080] In some embodiments, the second bend may be provided around the side periphery other than the position where the cover plate is movably connected to the housing. When the top cover 22 is rotated downward and closed on the housing, the inner wall of the second bend may be opposite to the corresponding outer surface on the housing and / or the side door 21.

[0081] It should be noted that the outer surface of the box refers to the surface located outside the box, and the outer surface of the side door 21 also refers to the surface of the side door 21 located outside the box.

[0082] For example, when the protective box 2 is a rectangular body, the bottom of the side door 21 is movably connected to the box body, and the top cover 22 is movably connected to the connecting wall 24 on the side of the box body away from the side door 21, a second bend with three bends can be formed on the cover plate. When the top cover 22 is closed on the box body, the inner wall of the second bend can be opposite to the outer surfaces of the two side walls 23 and the side door 21.

[0083] In this embodiment, the top cover 22 and the side door 21 can be locked together by a metal buckle 26, and the protective box 2 can be sealed by a customs seal 27.

[0084] In some embodiments, when the top cover 22 rotates downward and covers the box, the inner wall of the second bend can be spaced apart from the outer surface of the box, but is not limited thereto. When the top cover 22 rotates downward and covers the box, the inner wall of the second bend can also be fitted with the outer surface of the box. The specific settings can be made according to the actual situation.

[0085] like Figure 2 and Figure 3 As shown, in some embodiments, a safety valve 43 may also be provided on the top of the tank 1 for regulating the internal pressure of the tank 1. The safety valve 43 is located outside the protective box 2.

[0086] Furthermore, a surrounding plate 25 can be installed on the top of the tank 1. The height of the surrounding plate 25 is greater than the height of the safety valve 43, and it surrounds at least part of the side periphery of the safety valve 43. This can reduce or avoid the problem of the safety valve 43 colliding with structures in the external environment, thereby strengthening the protection of the safety valve 43. At the same time, gas can enter and exit the safety valve 43 through the opening at the top of the surrounding plate 25, so that the safety valve 43 can regulate the internal pressure of the tank 1.

[0087] For example, in this embodiment of the present disclosure, the enclosure 25 may be arranged around the safety valve 43 to enhance the protection of the safety valve 43.

[0088] It should be noted that when the safety valve 43 is located on the side of the enclosure away from the side door 21, and the orthogonal projection of the safety valve 43 on the protective enclosure 2 is located on the connecting wall 24 of the enclosure, the enclosure 25 can be connected to the connecting wall 24.

[0089] In this embodiment, the two side walls 23 in the housing can be extended away from the side door 21 to form a surrounding panel 25 that can completely cover the opposite sides of the safety valve 43.

[0090] like Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments, a support frame 5 can be provided at the bottom of the tank body 1, and the support frame 5 is connected to the bottom of the tank body 1. A set of slots can be provided on opposite sides of the support frame 5 to facilitate the forklift transport of the mobile tank.

[0091] For example, the support frame 5 may have a set of slots on each of the opposite sides in the transverse X direction. However, it is not limited to this; the support frame 5 may also have a set of slots on each of the opposite sides in the longitudinal Y direction. Alternatively, a set of slots may be provided on both the opposite sides in the transverse X direction and the longitudinal Y direction simultaneously to facilitate forklift transport of the mobile tank from multiple directions and improve the environmental adaptability of the mobile tank.

[0092] In some embodiments, the support frame 5 may include two parallel and spaced-apart crossbeams 52 and two parallel and spaced-apart longitudinal beams 53. The crossbeams 52 extend in the transverse direction X, and the longitudinal beams 53 extend in the longitudinal direction Y. The opposite ends of the crossbeams 52 are connected to the longitudinal beams 53 to form a "well"-shaped support frame 5. This can achieve support for the tank 1 while also reducing the weight of the support frame 5 to reduce transportation costs.

[0093] For example, the crossbeam 52 and the longitudinal beam 53 can be made of stainless steel rectangular steel pipes, and the crossbeam 52 and the longitudinal beam 53 can be connected by welding.

[0094] like Figure 1 , Figure 3 andFigure 7 As shown, in some embodiments, slot covers 51 can be provided on at least some slots on the support base 5. The slot covers 51 are movably connected to the support base 5 to seal the slots, thereby improving the problem of moisture from the external environment entering the slots and causing pollution and corrosion to the support base 5. It can also improve the problem of solid impurities such as dust entering the slots and hindering forklifts from passing through them. Furthermore, by providing slot covers 51 to cover the slots, the requirements of classification societies regarding the corrosion resistance of the forklift slots can also be met.

[0095] For example, in this embodiment of the present disclosure, slot covers 51 may be provided on all slots on the support base 5 to achieve sealing of each slot.

[0096] The slot cover 51 and the support base 5 can be connected by hinge, magnetic or other movable methods.

[0097] like Figure 7 As shown, in some embodiments, a screw 54 may be provided on the support base 5, corresponding to the slot. The slot cover 51 may include a cover plate and a connecting plate. The cover plate at least covers the slot, and its first end is hinged to the support base 5, while its second end is connected to the connecting plate. The connecting plate extends inward toward the cover plate, and its end away from the cover plate has a notch, the size of which is adapted to the screw 54.

[0098] It should be noted that the inner side of the cover plate refers to the side of the cover plate closest to the support base 5 when sealing the slot.

[0099] When the slot cover 51 is closed on the slot, the screw 54 can be inserted into the corresponding notch to seal the slot using the slot cover 51. A fastener can be threaded onto the screw 54. When the mobile can is being transported by forklift, the fastener can be moved towards the end of the screw 54 away from the support base, allowing the slot cover 51 to rotate relative to the support base and expose the slot. When forklift transport is not required, the fastener can be moved towards the end of the screw 54 closer to the support base 5 to secure the slot cover 51 to the screw 54 and achieve a seal between the slot cover 51 and the slot.

[0100] Specifically, when the fastener moves toward the end of the screw 54 that is close to the support base 5, the connecting plate can be pressed tightly onto the support base 5, thereby achieving the sealing of the slot cover 51 on the slot.

[0101] The first end of the slot cover 51 can be hinged to the support base 5 via a hinge, but it is not limited to this. The first end of the slot cover 51 and the support base 5 can also be hinged via other structures besides the hinge. The specific configuration can be set according to the actual situation.

[0102] The first end of the slot cover 51 can be detachably connected to the support base 5.

[0103] For example, when the first end of the slot cover 51 is hinged to the support base 5 via a hinge, the hinge may include a pivot and a cotter pin through a pin hole on the pivot. By removing the cotter pin on the pivot, the slot cover 51 can be removed from the support base 5, thereby meeting the customer's usage needs in multiple scenarios.

[0104] The first end of the slot cover 51 can be located on the side of the slot cover 51, but is not limited to this. The first end of the slot cover 51 can also be located on the top or bottom of the slot cover 51, depending on the actual situation.

[0105] like Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments, a support base may be connected to the bottom of the tank 1, and the support base may include at least one set of web plates 61. One set of web plates 61 may include two spaced-apart web plates 61 extending laterally along the X direction, and the two web plates 61 may be symmetrically arranged about the center of the tank 1. The top surface of the web plates 61 is in contact with the bottom surface of the tank 1 to provide support for the tank 1.

[0106] For example, the top surface shape of the web plate 61 can be adapted to the bottom surface shape of the tank 1. When the tank 1 is placed on the web plate 61, the top surface of the web plate 61 can be completely fitted with the bottom surface of the tank 1, thereby increasing the supporting force of the web plate 61 on the tank 1.

[0107] When the tank 1 is a horizontal tank, the support base may include multiple sets of web plates 61 evenly spaced along the longitudinal Y (i.e., the axial direction of the tank) to increase the connection surface between the support base and the tank 1 and enhance the stability of the connection between the tank 1 and the support base.

[0108] In some embodiments, a buffer member 62 may be provided on each of the two opposite outer sides of a set of web plates 61, and the maximum distance between the two buffer members 62 in the transverse X direction is greater than the maximum distance between the tank body 1 in the transverse X direction.

[0109] The buffer 62 can be detachably connected to the web plate 61 by bolts, which facilitates the removal and replacement of the buffer 62.

[0110] It should be noted that when there are two spaced-apart webs 61 in a set of webs 61, the side of one web 61 that is away from the other web 61 is the outer side of the web 61, and the outer sides of the two webs 61 in a set of webs 61 are the two opposite outer sides of the set of webs 61.

[0111] In a set of web plates 61, the side of one buffer 62 furthest from the other is the outer side of the buffer 62. The outer sides of the two buffers 62 in the set of web plates 61 are the two opposite outer sides of the two buffers 61. The maximum distance between the two buffers 62 in the transverse X direction refers to the distance between the two opposite outer sides of the two buffers 62 in the transverse X direction.

[0112] In this embodiment, a buffer 62 is provided on each of the two opposite outer sides of a set of web plates 61, and the maximum distance between the two buffers 62 in the lateral X direction is greater than the maximum distance between the tank body 1 in the lateral X direction. When the mobile tank is transported using a transport box or other structure, the buffer 62 can improve the problem of the mobile tank shaking and scraping or colliding with the external structure such as the transport box.

[0113] In some embodiments, the buffer 62 can be made of rubber, for example, NBR (nitrile butadiene rubber) can be used to make the buffer 62, thereby giving the buffer 62 good cushioning properties and good wear resistance, so as to extend the service life of the buffer 62. However, it is not limited to this, and the embodiments of this disclosure can also be made of other materials with good cushioning properties besides rubber, depending on the actual situation.

[0114] In some embodiments, the support base may further include a pad 63, which is disposed between the web 61 and the tank 1, and the area of ​​the top surface of the pad 63 near the tank 1 is larger than the area of ​​the top surface of the web 61. When the tank 1 is placed on the pad 63, the top surface of the pad 63 can completely fit against the bottom of the tank 1, thereby increasing the contact area between the support base and the tank 1 and reducing the contact stress between the support base and the tank 1.

[0115] The connection between the pad 63, the web plate 61, and the tank body 1 can be welded.

[0116] In some embodiments, the support base may further include stiffening plates 64 extending along the longitudinal direction Y. The stiffening plates 64 are disposed on opposite sides of the web 61 along the longitudinal direction Y and are connected to the web 61. The top surface of the stiffening plates 64 is connected to the bottom of the tank 1 to provide support for the tank 1.

[0117] The stiffening plate 64 can be trapezoidal to improve the load-bearing capacity of the support base. Through holes can be provided on the stiffening plate 64, allowing ropes to pass through and secure the mobile tank during transportation.

[0118] The stiffening plate 64 can be welded to the web plate 61 and the tank body 1.

[0119] It should be noted that when the mobile tank includes both a support base and a support frame 5, the support base can be located between the support frame 5 and the tank body 1. In this case, the tank body 1 and the support frame 5 are welded together through the support base to jointly bear various loads on the tank body 1 (and the internal medium) during transportation.

[0120] like Figures 8 to 10 As shown, in some embodiments, a connecting pipe 44 is provided on the top of the tank 1, and the connecting pipe 44 is connected to the inside of the tank 1.

[0121] For example, the connecting pipe 44 can be used to load and unload liquid inside the tank 1.

[0122] The valve 3 in this embodiment may include a connecting flange 31, a transition flange 32, and a control valve 33. The connecting flange 31 is disposed on the top of the tank body 1 and sleeved onto the connecting pipe 44, allowing the connecting pipe 44 to be detachably connected to the tank body 1, thus facilitating cleaning and maintenance of the connecting pipe 44 through disassembly. The transition flange 32 is located on the side of the connecting flange 31 away from the tank body 1 and is detachably connected to the connecting flange 31. The control valve 33 is located on the side of the transition flange 32 away from the connecting flange 31 and is detachably connected to the transition flange 32. The connecting pipe 44 passes through the connecting flange 31 and the transition flange 32 to communicate with the control valve 33.

[0123] For example, such as Figures 9 to 10 As shown, the top and bottom surfaces of the transition flange 32 both have sealing surfaces, and the transition flange 32 can be provided with multiple evenly spaced countersunk holes 34 and multiple evenly spaced threaded holes 35. The threaded holes 35 can be located between two adjacent countersunk holes 34. Fasteners can achieve a detachable connection between the transition flange 32 and the connecting flange 31 through the countersunk holes 34, and a detachable connection between the transition flange 32 and the control valve 33 through the threaded holes 35. The fasteners are installed in the four countersunk holes 34 and will not protrude from the top surface of the transition flange 32. The fasteners can be hex socket head cap screws.

[0124] This embodiment of the present disclosure provides an adapter flange 32 between the connecting flange 31 and the control valve 33. By changing the model of the adapter flange 32, the connecting flange 31 can be connected to different models of control valves 33, thereby adapting to different application requirements.

[0125] For example, the bottom surface of the transition flange 32 may be provided with four countersunk holes 34, and the top surface of the transition flange 32 may be provided with four threaded holes 35.

[0126] The transition flange 32 can be connected to the DN32 connecting flange 31 via the countersunk hole 34, and to the DN25 control valve 33 via the threaded hole 35. In other words, the transition flange 32 enables conversion between DN32 and DN25 specifications, allowing connection between the connecting flange 31 and different models of control valves 33, thus improving the environmental adaptability of the mobile tank. The inner bore of the transition flange 32 can be welded to the connecting pipe 44. When the transition flange 32 is connected to the connecting flange 31, the connecting pipe 44 can pass through the inner bore of the connecting flange 31 and extend into the tank body 1. For example, extending the connecting pipe 44 into the bottom of the tank body 1 allows for a larger inner diameter of the connecting pipe 44 and enables a detachable connection between the connecting pipe 44 and the tank body 1.
