Description

Technical Field

[0001] This utility model relates to the field of industrial production tank technology, and in particular to a conical bottom structure for assembled tanks. Background Technology

[0002] In industrial production, tanks are a common type of container widely used for storing various materials, including liquids, powders, and granules. Among them, tanks with a conical bottom structure are particularly favored due to their unique advantages. The conical bottom design allows for smoother material flow and discharge, and facilitates cleaning of the tank's interior, effectively improving the efficiency and convenience of material handling. Consequently, they have been widely used in numerous industrial scenarios.

[0003] Currently, most conical bottom plate structure tanks commonly found in China are constructed using a component welding method. Specifically, this structure typically involves dividing the tank into a frame section and a conical plate section, depending on the required transport capacity. In actual installation, the outer frame must be welded on-site first, followed by the welding of the conical bottom plate. This traditional component welding method has several drawbacks. Firstly, the overall construction is difficult, requiring specialized welding technicians and complex welding equipment. It demands a high level of technical skill and operational experience from the construction personnel; even slight errors can lead to welding quality problems, affecting the tank's sealing and overall structural strength. Secondly, the construction cycle is long. From component transportation and on-site assembly to welding completion, it consumes significant time and labor costs, making it difficult to meet the needs of industrial projects with high construction schedule requirements. Furthermore, this construction method is susceptible to environmental factors, such as severe weather conditions and complex site environments, which can adversely affect welding quality and construction progress, further increasing the risks and uncertainties of the construction process.

[0029] The following is combined Figures 1 to 6The present invention provides a detailed description of an assembled tank cone bottom structure through specific embodiments and application scenarios.

[0030] In the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a modular tank cone-bottom structure 10 includes a first tank body 100, a second tank body 200, and a support frame 300. The first tank body 100 is columnar; the second tank body 200 is cone-shaped and located below the first tank body 100. The top of the second tank body 200 is connected to the first tank body 100, and the bottom of the second tank body 200 has a discharge port 230. The second tank body 200 includes multiple bottom cone plates 210 and a connecting frame 220. The multiple bottom cone plates 210 are spliced ​​together to form a cone-shaped tank wall. The connecting frame 220 surrounds the outer side of the cone-shaped tank wall and is connected to the outer wall of the cone-shaped tank wall. The support frame 300 includes multiple support units 310. The multiple support units 310 frames are spliced ​​together to surround the outer side of the second tank body 200. One end of the support frame 300 is fixedly abutted against the outer side wall of the top of the second tank body 200, and the other end is used to connect to external components or the ground.

[0031] The first tank body 100 is cylindrical in shape and is mainly used for storing liquid, powder, or granular materials. Its cylindrical structure provides a large storage space, making it suitable for storing large quantities of materials.

[0032] Columnar structures have high mechanical strength and stability, and can withstand large internal pressure and external loads.

[0033] The top of the first tank body 100 can be connected to a feed inlet or other pipes, and the bottom is connected to the second tank body 200 to ensure that the material can flow smoothly from the first tank body 100 into the second tank body 200.

[0034] The second tank body 200 is cone-shaped and located below the first tank body 100. The cone-shaped bottom design allows materials to flow and be discharged more smoothly, reduces material residue at the bottom of the tank, and improves material handling efficiency.

[0035] The bottom of the second tank body 200 has a discharge port 230 for easy material discharge. The conical bottom design allows the material to be concentrated at the discharge port 230, ensuring complete discharge and reducing cleaning difficulty.

[0036] The second tank body 200 is composed of multiple bottom cone plates 210 and connecting frames 220. This splicing structure facilitates prefabrication in the factory and on-site assembly, improving construction efficiency and quality.

[0037] Multiple bottom conical plates 210 are spliced ​​together to form a conical tank wall. This splicing method allows the conical tank wall to be customized as needed, adapting to tank designs of different sizes and shapes. The bottom conical plates 210 can be prefabricated in the factory, ensuring their dimensional accuracy and quality. After the prefabricated bottom conical plates 210 are transported to the site, they are spliced ​​and bolted together, reducing the amount of on-site processing work.

[0038] The connecting frame 220 surrounds the outer side of the conical tank wall and is connected to the outer wall of the conical tank wall. It provides additional structural support to the conical tank wall, enhancing its strength and stability. The connecting frame 220 can be prefabricated in the factory and then bolted to the conical tank wall after transportation to the site, improving the convenience and speed of assembly. The connecting frame 220 also protects the conical tank wall from external impacts and damage, extending the service life of the tank.

[0039] The support frame 300, consisting of multiple support units 310, is spliced ​​together and encloses the outer side of the second tank body 200, providing overall support for the entire conical bottom plate structure and ensuring the stability and safety of the tank. One end of the support frame 300 is fixedly abutted against the outer wall of the top of the second tank body 200, while the other end is used to connect to external components or the ground. This connection method ensures the stability and safety of the tank during use, preventing displacement or deformation. The support unit 310 frames can be prefabricated in the factory and then spliced ​​and bolted together on site, reducing on-site processing workload and improving construction efficiency.

[0040] This application clearly divides the tank body into a first tank body 100, a second tank body 200, and a support frame 300. This allows each component to have a relatively independent shape and structure, enabling mass production in a factory according to uniform standards and processes. The second tank body 200 is composed of multiple bottom conical plates 210 and a connecting frame 220. The bottom conical plates 210 are spliced ​​together to form a conical tank wall. The bottom conical plates 210 and the connecting frame 220 can be prefabricated in the factory. The support frame 300 is composed of multiple support units 310 spliced ​​together. The support units 310 can also be prefabricated in the factory. The first tank body 100 can be manufactured in the factory, depending on its height, after determining whether it needs to be divided. After the components are manufactured in the factory, they are transported to the site as needed and assembled and fixed through splicing, bolting, etc., such as connecting the connecting frame 220 to the outer wall of the conical tank wall, and fixing the support frame 300 to the top outer wall of the second tank body 200. Thus, this application adopts a method of factory prefabrication and on-site assembly and bolting of the conical bottom structure 10 of the assembled tank, which avoids a large amount of complex on-site processing and connection work, reduces the construction difficulty, and at the same time, the parallel prefabrication and rapid on-site assembly of various components greatly shortens the construction cycle.

[0041] Reference Figure 3 and Figure 4 According to the present invention, a conical bottom structure 10 for an assembled tank body is provided, wherein multiple bottom conical plates 210 are arranged in a circular array, and adjacent bottom conical plates 210 are fixed together by bolting.

[0042] Understandably, the arrangement of multiple bottom conical plates 210 in a circular array ensures the integrity and continuity of the conical tank wall, allowing the bottom conical plates 210 to be evenly distributed across the entire conical tank wall, forming a complete conical structure, thereby guaranteeing the shape and function of the tank.

[0043] The ring array arrangement allows each bottom cone plate 210 to bear the pressure and weight from the material evenly, avoiding the problem of excessive local stress and improving the overall strength and stability of the tank.

[0044] The circular array arrangement facilitates the splicing and assembly of the bottom cone plates 210, making the on-site assembly process more efficient and convenient. The circular array layout makes the connection between the bottom cone plates 210 more regular, reducing errors and complexity in the assembly process.

[0045] Bolting is a quick and convenient connection method that does not require complex welding equipment or professional welding technicians. Through bolting, the connection between the bottom cone plates 210 can be completed quickly on-site, significantly shortening the construction period.

[0046] Reference Figure 3 and Figure 4 According to the present invention, a conical bottom structure 10 for an assembled tank body is provided. The connecting frame 220 includes multiple reinforcing main beams 221 and multiple circumferential tie rods 222. The multiple reinforcing main beams 221 are arranged in a ring on the outside of the conical tank wall. The reinforcing main beams 221 extend from the discharge port 230 toward the joint between the first tank body 100 and the second tank body 200 and are attached to the outer wall surface of the conical tank wall. The multiple circumferential tie rods 222 are arranged at intervals along the axis of the second tank body 200 on the conical tank wall and are connected to the reinforcing main beams 221.

[0047] Understandably, multiple reinforcing main beams 221 are arranged in a ring array on the outside of the conical tank wall, extending from the discharge port 230 towards the joint between the first tank body 100 and the second tank body 200, and affixed to the outer wall surface of the conical tank. This arrangement allows the reinforcing main beams 221 to effectively bear the load in the longitudinal direction of the tank. When the tank is filled with material, the gravity generated by the material acts on the bottom of the tank. The reinforcing main beams 221 can disperse and transfer these longitudinal forces to other parts of the tank, thereby enhancing the longitudinal load-bearing capacity of the entire conical bottom structure and preventing the tank from undergoing longitudinal deformation or damage due to excessive material weight.

[0048] Multiple circumferential tie rods 222 are spaced apart along the axis of the second tank body 200 on the conical tank wall and connected to the reinforcing main beam 221. The main function of the circumferential tie rods 222 is to enhance the strength of the conical tank wall in the circumferential direction. Under the influence of internal pressure or external forces, the conical tank wall may be subjected to circumferential stress. The circumferential tie rods 222 can effectively resist this stress, prevent circumferential cracking or deformation of the tank wall, and ensure the sealing and structural integrity of the tank.

[0049] Reference Figure 3 and Figure 4 According to the present invention, a conical bottom structure 10 for an assembled tank body is provided, wherein the joint between the main beam 221 and the two adjacent bottom conical plates 210 is correspondingly set.

[0050] It is understandable that strengthening the main beam 221 and the corresponding joint setting can effectively limit the displacement at the joint and maintain the relative position stability between the bottom cone plates 210.

[0051] As a crucial load-bearing component in the tank structure, the reinforcing main beam 221, positioned corresponding to the joint, guides the rational transmission of forces. When the tank is subjected to external forces, the force first acts on the tank surface and then is transmitted to the reinforcing main beam 221 through the bottom cone plate 210. Because the reinforcing main beam 221 corresponds to the joint, the force can be transmitted more smoothly along the reinforcing main beam 221 to other supporting parts of the tank, such as the support frame 300. This rational force transmission path avoids force accumulation at the joint and reduces structural damage caused by unreasonable stress distribution.

[0052] Meanwhile, by strengthening the corresponding design of the main beam 221 and the joints, the tank body can be more balanced in terms of force in all directions. During the use of the tank body, different directions may be subjected to forces of different magnitudes. Strengthening the main beam 221 can be carried out in a targeted manner according to the force distribution, so that the tank body can withstand the corresponding loads in all directions and improve the overall mechanical performance of the tank body structure.

[0053] Reference Figure 3 and Figure 4 According to the present invention, a conical bottom structure 10 for an assembled tank body is provided, wherein the circumferential tie rod 222 includes multiple tie rod segments 313, and the tie rod segments 313 and the reinforcing main beam 221 are arranged in an alternating manner.

[0054] Understandably, the staggered arrangement of the tie rod 313 segments and the reinforcing main beam 221 forms a spatial grid structure, connecting the dispersed tank components into a unified whole, so that the conical tank wall is effectively supported in all directions, significantly enhancing the overall structural stability of the tank.

[0055] Reference Figure 5 and Figure 6According to the present invention, a conical bottom structure 10 for an assembled tank body is provided. The support unit 310 includes at least two support columns 311, multiple circumferential beams 312 and multiple tie rods 313. The two support columns 311 are arranged vertically side by side and spaced apart from each other. The circumferential beams 312 are arranged horizontally between the two support columns 311 and are connected and fixed to the support columns 311. The tie rods 313 are cross-connected between two adjacent support columns 311 and are located in the area enclosed by the circumferential beams 312 and the support columns 311.

[0056] Understandably, the two supporting columns 311 are arranged vertically side by side and spaced apart from each other, providing crucial vertical support for the entire assembled tank's conical bottom structure 10. The weight of the tank itself and the weight of the materials contained inside are transferred to the supporting columns 311 through the conical bottom structure. The supporting columns 311 can bear and distribute these vertical loads, ensuring the vertical stability of the tank and preventing the tank from sinking or experiencing uneven settlement due to gravity.

[0057] Multiple circumferential beams 312 are arranged laterally at intervals between two support columns 311 and are connected and fixed to the support columns 311. The circumferential beams 312 can enhance the stability of the support unit 310 in the lateral direction and resist the action of lateral external forces.

[0058] Tie rods 313 cross-connect between two adjacent support columns 311 and are located within the area enclosed by the circumferential beam 312 and the support columns 311. The presence of tie rods 313 enhances the tightness of the connection between the components of the support unit 310, making the support columns 311, the circumferential beam 312 and the tie rods 313 form an organic whole.

[0059] Reference Figure 5 and Figure 6 According to the present invention, the assembled tank cone bottom structure 10 also includes a ring beam 400. The ring beam 400 is arranged around the end of the support frame 300 that abuts against the second tank body 200. The ring beam 400 includes multiple ring beam 400 segments, and the ring beam 400 segments are arranged one-to-one with the support unit 310. The ring beam 400 segments are bolted to the support unit 310.

[0060] Understandably, the ring beam 400 is positioned at the end where the support frame 300 abuts against the second tank body 200, serving to connect the support frame 300 and the second tank body 200. This ensures a tight connection between the support frame 300 and the tank body, enhancing the overall structural stability.

[0061] The ring beam 400 comprises multiple ring beam segments, each corresponding to a support unit 310. This allows the ring beams 400 to be prefabricated in the factory and quickly assembled on site, improving construction efficiency.

[0062] The 400-segment ring beam is fixed to the support unit 310 by bolting. Bolting is a quick and convenient connection method that does not require complex welding equipment or professional welding technicians, and the assembly process is fast and efficient.

[0063] Reference Figure 5 and Figure 6 According to the assembly tank cone bottom structure 10 provided by this utility model, the support frame 300 also includes multiple frame supports 320. The frame supports 320 are respectively arranged in correspondence with the support columns 311. One end of the frame support 320 is connected to the support column 311, and the other end extends upward towards the middle of the second tank body 200 and abuts against the reinforcing main beam 221.

[0064] Understandably, one end of the frame support 320 is connected to the support column 311, and the other end extends obliquely upward toward the middle of the second tank body 200, abutting against the reinforcing main beam 221. This allows the frame support 320 to provide support not only in the vertical direction but also in the horizontal direction, enhancing the multi-directional stability of the structure.

[0065] The inclined frame support 320, support column 311, and reinforcing main beam 221 form a triangular structure. The triangular structure has extremely high stability and can effectively resist external forces in various directions, reducing structural deformation.

[0066] Reference Figure 3 and Figure 4 According to the present invention, a conical bottom structure 10 for an assembled tank body is provided, wherein a bevel 221a is formed on the end of the main beam 221 away from the discharge port 230, and the bevel 221a is used to avoid the ring beam 400.

[0067] Understandably, the bevel 221a formed on the reinforcing main beam 221 is used to avoid the ring beam 400, ensuring that the ring beam 400 can be smoothly installed at the end of the reinforcing main beam 221 during assembly without structural interference. This improves structural compatibility and allows the various components to work together better.

[0068] Reference Figure 1 and Figure 2 According to the present invention, a conical bottom structure 10 for an assembled tank body is provided. The first tank body 100 includes multiple tank units 110, which are arranged in a ring. The multiple tank units 110 are connected end to end along the height direction to form the first tank body 100.

[0069] Understandably, the first tank body 100 is divided into multiple tank units 110, each of which can be prefabricated in a factory. This makes the manufacturing of each unit more standardized and precise, improving production efficiency and quality control. The prefabricated tank units 110 facilitate transportation, especially for large tanks, where segmented transportation can significantly reduce transportation costs and difficulties.

[0070] At the construction site, the prefabricated tank units 110 can be quickly assembled, greatly shortening the construction cycle. By connecting the ends of the tank units 110, they can be quickly assembled into a complete tank structure.

[0071] Adjacent tank units 110 can be quickly connected by snap-fit ​​or socket-fitting to improve assembly efficiency.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
