Description

Technical Field

[0001] This utility model relates to the field of metallurgical production facility technology, specifically to a multi-point supported steel silo ring beam structure. Background Technology

[0002] In batching systems within the metallurgical industry, steel silos are commonly used to store raw materials. These materials are then weighed according to a specific ratio and discharged from the silo's discharge port to meet production demands, thus ensuring production continuity and efficiency. This necessitates that the steel silos possess weighing capabilities. In existing batching systems, multiple load cells are evenly distributed at the bottom of the silo's ring beam structure. These load cells serve as support points for the ring beam structure, which supports the entire silo. The ring beam structure experiences significant stress, placing high demands on its load-bearing capacity.

[0003] The traditional approach uses a closed-section box-type ring beam structure. While this structure offers high bending stiffness and good torsional resistance, it also presents significant challenges for welding and construction, making it difficult to detect defects and creating potential safety hazards. Designers address these issues by increasing the safety factor, which inevitably leads to some steel waste. Furthermore, construction sites frequently report difficulties such as excessive welding work and insufficient construction space associated with box-type ring beam structures.

[0004] In summary, there is an urgent need for a multi-point supported steel silo ring beam structure to solve the problems existing in the current technology. Utility Model Content

[0025] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Example:

[0028] See Figures 1-4 A multi-point supported steel silo ring beam structure includes a central vertical stiffening plate and an upper annular support 1 and a lower annular support 2 arranged around the outer wall of the steel silo. The outer wall of the steel silo is provided with multiple central vertical stiffening plates spaced apart along the circumference. The inner side of the central vertical stiffening plate is connected to the silo wall 7 of the steel silo. The central vertical stiffening plate is located between the upper annular support 1 and the lower annular support 2, and its upper end and lower end are respectively connected to the upper annular support 1 and the lower annular support 2 (that is, the upper end of the central vertical stiffening plate is connected to the upper annular support, and its lower end is connected to the lower annular support). Multiple support points are evenly distributed along the circumference on the lower annular support 2. The support points support the steel silo, and the evenly distributed multiple support points ensure that the steel silo is subjected to uniform stress.

[0029] like Figures 1-4 As shown, the lower annular support 2 includes a lower annular support 2.1 and a lower annular support plate 2.2 disposed at the support point. Multiple lower annular support 2.1 and multiple lower annular support plates 2.2 are alternately arranged to form an annular structure. The middle vertical stiffening plate includes a middle vertical stiffening plate 3 and a middle vertical stiffening plate 6. Multiple middle vertical stiffening plates 3 are provided circumferentially between the lower annular support 2.1 and the upper annular support 1. Multiple middle vertical stiffening plates 6 are provided circumferentially between the lower annular support plate 2.2 and the upper annular support 1. In the structural configuration of this embodiment, the bottom width of the lower ring support 2.1 and the bottom width of the lower ring support plate 2.2 may not be the same, and different profiles can be selected for both. Setting the lower ring support plate 2.2 at the support point can form a larger force-bearing surface at the support point, thereby providing a larger installation space for the support device and preventing interference between the support device and the steel silo due to insufficient installation space at the support point.

[0030] like Figures 2-4As shown, the multi-point supported steel silo ring beam structure also includes upper vertical stiffening plates 4. Multiple upper vertical stiffening plates 4 are spaced apart along the circumference of the steel silo. The inner side of each upper vertical stiffening plate 4 is connected to the silo wall 7, and its lower end is connected to the upper end of the upper annular support member 1. Furthermore, the multi-point supported steel silo ring beam structure also includes lower vertical stiffening plates 5. Multiple lower vertical stiffening plates 5 are spaced apart along the circumference of the steel silo. The inner side of each lower vertical stiffening plate 5 is connected to the silo wall 7, and its upper end is connected to the lower end of the lower annular support member 2.1. In this preferred embodiment, the upper vertical stiffening plate 4, the lower vertical stiffening plate 5, and the middle vertical stiffening plate 3 are vertically aligned, and the upper vertical stiffening plate 4 and the middle vertical stiffening plate 6 are vertically aligned. The upper vertical stiffening plates 4 are evenly arranged at intervals of approximately 5°-15° along the radial direction of the steel silo. The upper vertical stiffening plates 4, the middle vertical stiffening plate, and the lower vertical stiffening plate 5 provide better bending and torsional stiffness for the ring beam structure.

[0031] like Figure 2 and Figure 4 As shown, a support point stiffening plate 8 is provided between two adjacent central vertical stiffening plates 6. The lower side of the support point stiffening plate 8 is connected to the lower ring support plate 2.2, and its two ends are connected to the two adjacent central vertical stiffening plates 6. A transverse stiffening plate 9 is provided between two adjacent central vertical stiffening plates 6. The inner side of the transverse stiffening plate 9 is connected to the silo wall 7 of the steel silo, and its two ends are connected to the two adjacent central vertical stiffening plates 6. The support point stiffening plate 8 and the transverse stiffening plate 9 can greatly improve the overall stiffness of the ring beam structure at the support point position.

[0032] like Figures 2-4 As shown, a support platform 16 is provided below the lower ring support plate 2.2. A weighing device 11 and a jack 17 are provided on the support platform 16, and the lower ring support plate 2.2 is supported by the weighing device 11 or the jack 17. Furthermore, a pad 10 is provided on the bottom surface of the lower ring support plate 2.2, which allows the steel silo to rest on the weighing device 11 or the jack 17. The pad 10 effectively mitigates the problem of excessively concentrated reaction force at the support point. The jack 17 is used to support the lower ring support plate 2.2 during maintenance of the weighing device 16.

[0033] like Figure 1 and Figure 2As shown, the bottom surface of the lower ring support plate 2.2 is provided with limiting members 12. Some of the limiting members 12 on the lower ring support plate 2.2 are located on the clockwise side of the support platform 16 below them, and some of the limiting members 12 on the lower ring support plate 2.2 are located on the counterclockwise side of the support platform 16 below them, thereby achieving circumferential limiting of the steel silo. Furthermore, the number of the lower ring support plates 2.2 (i.e., support points) can be odd or even, and the lower ring support plates 2.2 are evenly distributed along the circumference, as long as they satisfy the requirement of circumferential limiting of the steel silo.

[0034] like Figure 2 As shown, a limiting baffle 15 is provided on the side of the support platform 16 near the limiting member 12, and a gap of 5-10mm is left between the limiting member 12 and the limiting baffle 15. The limiting baffle 15 prevents the limiting member from causing wear on the support platform 16, and the gap between the limiting member 12 and the limiting baffle 15 is to facilitate the installation of the steel silo.

[0035] Preferably, the limiting member 12 includes an H-beam 13 and a limiting stiffening plate 14. The upper end of the H-beam 13 is fixedly connected to the lower ring support plate 2.2, and the limiting stiffening plate 14 is disposed between the two flange plates of the H-beam 13 to achieve structural reinforcement of the H-beam.

[0036] In this embodiment, the upper annular support 1 and the lower annular support 2.1 are angle steel. Of course, in some embodiments, T-shaped steel, I-beam steel, etc. may also be used. Using prefabricated profiles can greatly reduce the amount of welding work of the ring beam structure, making the welding work more convenient and faster, and improving the overall quality of the ring beam structure.

[0037] The effect of applying the technical solution of this embodiment is:

[0038] The ring beam structure provided in this embodiment is connected to the silo wall through stiffening plates and supporting components, exhibiting good overall rigidity and fully utilizing the load-bearing capacity of the ring beam structure. The ring beam structure in this embodiment has an open side profile, making welding of the internal welds during construction more convenient and efficient. This improves construction efficiency and allows for effective inspection of weld quality, thereby reducing the probability of safety and quality issues. Furthermore, the safety factor of the ring beam structure can be reduced to a reasonable range, further decreasing the amount of steel used.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
