Description

Technical Field

[0001] This utility model belongs to the field of storage container technology, and more specifically, it relates to a saddleless horizontal container. Background Technology

[0002] In industrial sectors such as chemical and energy, traditional horizontal vessels commonly employ saddle supports as their structural support. When horizontal vessels utilize double saddle supports, with the increasing integration and scale of engineering projects, significant bending moments and shear forces can easily occur in the middle sections of the vessel body or at the saddle supports. This mechanical condition can lead to equipment instability or plastic deformation, severely impacting the safety and reliability of the horizontal vessel.

[0003] Furthermore, the design of the saddle wrap angle has a crucial impact on the stability and strength of horizontal vessels. If the saddle wrap angle is too small, the stress on the vessel will increase significantly, which will not only easily cause instability or plastic deformation of the vessel, but also weaken the strength of the saddle itself, leading to the risk of stress exceeding limits or even structural failure.

[0004] To optimize stress and strength distribution and ensure equipment safety, existing technologies often employ methods such as increasing the number of saddles or increasing the container wall thickness. This allows multiple saddles to distribute the force and bending moment, thereby optimizing the stress state of the container shell, or increasing the container wall thickness to improve its strength. However, increasing the number of saddles and increasing the container wall thickness introduces new problems such as structural complexity and increased costs. Utility Model Content

[0005] The purpose of this invention is to provide a saddle-free horizontal container, which aims to solve the problem that using saddles to support horizontal containers requires increasing the container thickness and the number of saddles in order to optimize stress and strength distribution, resulting in complex structures and increased costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A saddleless horizontal container is provided, comprising a plurality of receiving bodies distributed along a first path, the interiors of the plurality of receiving bodies being interconnected to form a receiving space. Each receiving body includes a receiving portion, a transition portion, and a support portion distributed sequentially along the first path, the receiving portion, the transition portion, and the support portion being interconnected. The support portion has a polygonal cross-section and a plane at its bottom for providing support force. The outer peripheral surface of the support portion protrudes beyond the outer peripheral surface of the receiving portion.

[0008] In one possible implementation, the receiving portion has an annular cross-section, one end of the transition portion is adapted to the receiving portion, the other end is adapted to the support portion, and the middle region of the transition portion is smoothly transitioned.

[0009] In one possible implementation, a plurality of the receiving bodies are sequentially distributed along the first path, and the saddleless horizontal container further includes a connecting portion disposed between two adjacent receiving bodies, the connecting portion being connected to the receiving body, one end of the connecting portion being adapted to the receiving portion, and the other end being adapted to the support portion.

[0010] In one possible implementation, two adjacent receiving bodies are arranged mirror-symmetrically about a second path as an axis of symmetry, the second path being perpendicular to the first path.

[0011] In one possible implementation, the saddleless horizontal container includes two receiving bodies arranged along the first path, the receiving portions of the two receiving bodies being connected to each other, and an extension region corresponding to each receiving body. The extension region includes a connecting portion connected to the support portion and an extension portion connected to the connecting portion. One end of the connecting portion is sealed to the support portion, and the other end is sealed to the extension portion. The outer peripheral surface of the extension portion is recessed within the support portion, and the extension portion has a hemispherical end face.

[0012] In one possible implementation, the outer peripheral surface of the support is provided with reinforcing ribs connected end to end, and multiple reinforcing ribs are distributed at intervals along the first path.

[0013] In one possible implementation, the saddleless horizontal container further includes a reinforcing seat, which is a trapezoidal structure with a gradually changing height and is connected to the bottom of the transition section. The reinforcing seat is used to level the bottom of the transition section, and the bottom of the reinforcing seat is flush with the bottom of the support section.

[0014] In one possible implementation, a flexible cushioning pad is provided between the reinforcing seat and the transition portion.

[0015] In one possible implementation, the angle between the outer wall of the transition section and the horizontal plane is 15°-25°.

[0016] In one possible implementation, the saddleless horizontal container further includes a protective sleeve disposed outside the support portion, the protective sleeve being located at the connection between the support portion and the transition portion, and being an elastic member.

[0017] The beneficial effects of the saddle-less horizontal container provided by this utility model are as follows: Compared with the prior art, the saddle-less horizontal container of this utility model forms a receiving space through multiple interconnected receiving bodies. Support is provided by the contact between the support part and the support surface, eliminating the need for traditional saddle supports and avoiding the structural complexity and increased installation costs caused by increasing the number of saddles. Simultaneously, the support part adopts a polygonal cross-section and has a flat bottom, which can directly provide stable support force. Compared with the traditional saddle support method, this optimizes the stress and strength distribution of the horizontal container, effectively avoiding instability and plastic deformation caused by excessive bending moments and shear forces in the middle or support areas. Furthermore, the outer circumference of the support part protrudes beyond the outer circumference of the receiving part, further enhancing the overall stability of the container. While ensuring equipment safety and reliability, it eliminates the need to increase the container wall thickness, reducing material costs and manufacturing difficulty, achieving multiple advantages of simplified structure, reduced cost, and improved performance for the horizontal container.

[0027] Please refer to the following: Figures 1 to 5 The saddleless horizontal container provided by this utility model will now be described. The saddleless horizontal container includes multiple receiving bodies distributed along a first path. The interiors of the multiple receiving bodies are interconnected to form a receiving space. Each receiving body includes a receiving part 1, a transition part 2, and a support part 3 distributed sequentially along the first path. The receiving part 1, the transition part 2, and the support part 3 are interconnected. The cross-section of the support part 3 is polygonal, and the bottom has a plane for providing support force. The outer peripheral surface of the support part 3 protrudes from the outer peripheral surface of the receiving part 1.

[0028] The saddle-less horizontal container provided by this utility model, compared with the prior art, forms a receiving space through multiple interconnected receiving bodies. Support force is provided by the contact between the support part 3 and the support surface, eliminating the need for traditional saddle supports and avoiding the structural complexity and increased installation costs associated with increasing the number of saddles. Simultaneously, the support part 3 adopts a polygonal cross-section and has a flat bottom, directly providing stable support force. Compared with traditional saddle support methods, this optimizes the stress and strength distribution of the horizontal container, effectively preventing instability and plastic deformation caused by excessive bending moments and shear forces in the middle or at the support points. Furthermore, the outer circumference of the support part 3 protrudes beyond the outer circumference of the receiving part 1, further enhancing the overall stability of the container. While ensuring equipment safety and reliability, it eliminates the need to increase the container wall thickness, reducing material costs and manufacturing difficulty, achieving multiple advantages of simplified structure, reduced cost, and improved performance for the horizontal container.

[0029] Specifically, the support portion 3 or the receiving portion 1 located at the end is closed, so that the entire container forms a complete receiving space.

[0030] Optionally, the cross-section of the support part 3 is rectangular.

[0031] In some embodiments, please refer to Figures 1 to 4 The cross-section of the receiving part 1 is annular, one end of the transition part 2 is adapted to the receiving part 1, the other end is adapted to the support part 3, and the middle area of ​​the transition part 2 is smoothly transitioned.

[0032] In this embodiment, the receiving section 1 adopts an annular cross-section, which can fully utilize the mechanical properties of the annular structure, evenly distribute the internal pressure, effectively avoid local stress concentration, improve the container's ability to bear the pressure of the internal medium, and enhance its structural strength and stability. The transition section 2 connects the receiving section 1 at one end and the support section 3 at the other end, and the design of the smooth transition in the middle area not only makes the fluid flow in the receiving space less resistant, reduces energy loss, and ensures the smoothness of medium transmission, but also eliminates the potential stress concentration caused by abrupt changes in the cross-section, avoiding the formation of stress weak points at the transition. Combined with the polygonal structure of the support section 3, the stress transmission from the receiving section 1 to the support section 3 of the entire container is smoother and more uniform, further improving the overall performance and reliability of the saddleless horizontal container and extending the service life of the equipment.

[0033] Optionally, the cross-section of the receiving part 1 is circular or elliptical.

[0034] In some embodiments, please refer to Figure 5 Multiple containment bodies are distributed sequentially along the first path. The saddleless horizontal container also includes a connecting part 7 located between two adjacent containment bodies. The connecting part 7 is connected to the containment body, with one end of the connecting part 7 adapted to the containment part 1 and the other end adapted to the support part 3.

[0035] The connecting part 7 is fitted to the receiving part 1 at one end and the supporting part 3 at the other end. This precise fitting structure makes the connection between the components tighter and more stable, ensuring a clear and efficient force transmission path when the container is subjected to pressure and external forces, reducing stress loss and energy consumption. At the same time, the interconnected design of the connecting part 7 ensures smooth flow of the medium inside the container, avoiding local blockages or eddies caused by poor connections, and improving the efficiency of medium transmission. In addition, this structural design strengthens the overall integrity of the container, enhances its resistance to changes in the external environment and mechanical vibration, reduces the risk of leakage caused by improper component connections, and further improves the safety and reliability of the saddleless horizontal container operation.

[0036] Optionally, the connecting part 7 has the same cross-section as the receiving part 1, that is, the shape and size are exactly the same.

[0037] Optionally, if the end of the horizontal container without a saddle is a support part 3, a transition part 2 is also connected to the outside of the support part 3, and the outer end face of the transition part 2 forms a hemispherical closed surface.

[0038] In some embodiments, please refer to Figures 2 to 3 The two adjacent containing bodies are mirror-symmetrically arranged with the second path as the axis of symmetry, and the second path is perpendicular to the first path.

[0039] The two adjacent receiving bodies are mirror symmetrical, that is, the receiving part 1 is connected to the adjacent receiving part 1, and the support part 3 is connected to the adjacent support part 3. This avoids the problem of introducing a connection structure due to the inconsistent size of adjacent parts, reduces the process complexity caused by structural differences, improves production efficiency and reduces manufacturing costs.

[0040] In some embodiments, please refer to Figure 3 The saddleless horizontal container includes two receiving bodies arranged along a first path, the receiving parts 1 of the two receiving bodies are connected to each other, and also includes an extension area corresponding to each receiving body. The extension area includes a connecting part 4 connected to the support part 3 and an extension part 5 connected to the connecting part 4. One end of the connecting part 4 is sealed and connected to the support part 3, and the other end is sealed and connected to the extension part 5. The outer peripheral surface of the extension part 5 is recessed within the support part 3, and the extension part 5 has a hemispherical end face.

[0041] The extension section 4 is sealed to the support section 3, ensuring the overall sealing of the container. Simultaneously, the outer circumference of the extension section 5 is recessed within the support section 3, creating a smooth transition and effectively reducing the risk of localized stress concentration caused by structural abrupt changes. The hemispherical end face design not only conforms to the optimal stress distribution of a pressure vessel, evenly distributing internal pressure, but also reduces eddies and media deposition in the end region, improving the container's hydrodynamic performance. Furthermore, the extension section expands the overall length of the container, allowing for flexible volume adjustment according to actual needs without altering the main structural design, thus enhancing the equipment's adaptability.

[0042] Optionally, the outer peripheral surface of the extension 5 is annular, consistent with that of the receiving part 1.

[0043] In some embodiments, not shown in the figure, the outer peripheral surface of the support portion 3 is provided with reinforcing ribs connected end to end, and multiple reinforcing ribs are distributed at intervals along the first path.

[0044] The annular arrangement of the reinforcing ribs effectively enhances the radial stiffness and deformation resistance of the support section 3, better resisting the circumferential stress generated by internal pressure and preventing local buckling or deformation of the support section 3 under load. The spaced reinforcing ribs ensure structural lightweighting and, through a rational rib layout, create a uniform stress distribution, significantly improving the container's bending and shear resistance. Furthermore, the reinforcing rib design increases the contact stability between the support section 3 and the support surface, reducing the impact of vibration or load fluctuations on the container, further enhancing the reliability and safety of the equipment during long-term operation.

[0045] In some embodiments, please refer to Figure 2 The saddleless horizontal container also includes a reinforcing seat 6, which is a trapezoidal structure with a gradually changing height and is connected to the bottom of the transition section 2. The reinforcing seat 6 is used to level the bottom of the transition section 2, and the bottom of the reinforcing seat 6 is flush with the bottom of the support section 3.

[0046] The trapezoidal gradient structure of the reinforcing seat 6 seamlessly connects the bottom height difference between the transition section 2 and the support section 3, achieving a smooth transition and effectively eliminating stress concentration caused by abrupt structural changes, significantly improving the container's bending and fatigue resistance. This structure, by leveling the bottom of the transition section 2, ensures that the bottoms of the support section 3 and the reinforcing seat 6 are flush, not only guaranteeing the overall stability of the container's support but also optimizing the load transfer path, resulting in a more even distribution of stress. Simultaneously, the trapezoidal reinforcing seat 6 design enhances the local stiffness of the transition zone while avoiding material redundancy, achieving both structural strength and lightweight design.

[0047] In some embodiments, please refer to Figure 2 A flexible buffer pad is provided between the reinforcing seat 6 and the transition part 2.

[0048] The buffer pad effectively absorbs the vibration energy generated by internal pressure fluctuations or external load changes in the container, significantly reducing the impact of stress transmission on the transition zone and preventing structural fatigue damage. The addition of the flexible buffer layer not only improves the stress distribution between the reinforcing seat 6 and the container body, making load transmission more gentle and uniform, but also compensates for minor deviations during installation, ensuring the support system is always in optimal stress condition. Furthermore, the buffer pad avoids rigid contact between the reinforcing seat 6 and the transition section 2, ensuring the service life of the transition section 2.

[0049] Optionally, the cushioning pad can be a rubber pad or an EVA pad.

[0050] In some embodiments, please refer to Figure 2 The angle between the outer wall of the transition section 2 and the horizontal plane is 15°-25°.

[0051] The angle between the outer wall of transition section 2 and the horizontal plane is controlled within the optimized range of 15°-25°, achieving the best smooth transition effect of stress transfer, avoiding local stress concentration caused by abrupt angle changes, and making the container wall more uniformly stressed.

[0052] In some embodiments, not shown in the figures, the saddleless horizontal container also includes a protective sleeve disposed outside the support portion 3. The protective sleeve is located at the connection between the support portion 3 and the transition portion 2 and is an elastic member.

[0053] As a buffer layer for the critical connection point 7, the protective sleeve effectively absorbs and disperses vibration energy and impact loads generated during container operation, preventing excessive stress concentration in the structural transition zone. The elastic properties of the protective sleeve ensure a flexible connection between the support part 3 and the transition part 2, avoiding stress concentration problems caused by rigid connections, while also compensating for minor deformations caused by temperature changes or pressure fluctuations, ensuring the sealing reliability of connection point 7. This design is particularly suitable for operating environments with thermal expansion and contraction or cyclic loads, significantly reducing the risk of fatigue damage to connection point 7 while maintaining overall structural rigidity, thus extending the service life of the equipment.

[0054] Optionally, the protective sleeve is made of rubber.

[0055] 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.
