Description

Conical top cover of solid silo and solid silo Technical Field

[0001] This utility model belongs to the field of material storage, and more specifically, it relates to a conical top cover for a solid silo. This utility model also relates to a solid silo. Background Technology

[0002] A silo is a storage device in a mechanized bulk material handling system, primarily serving as an intermediate storage unit, system buffer, and balancing unit. A silo is a container for storing materials, typically constructed of steel or reinforced concrete. The geometry of a silo is generally cylindrical or prismatic at the top, tapering to a conical funnel shape with a discharge port at the bottom. Materials inside the silo are discharged and transferred via the bottom discharge port under their own weight.

[0003] The conical top cover of a silo, as a crucial component, plays a vital role in preventing material leakage and bearing the weight of the materials. However, in practical applications, due to factors such as internal pressure, snow load, the weight of the top equipment, and corrosion, the conical top cover is prone to fatigue damage and cracking, thus affecting the normal operation and safety of the silo. Therefore, developing a reinforced conical top cover structure with high load-bearing capacity and durability is of great significance. Summary of the Invention

[0004] The purpose of this invention is to provide a conical top cover for a solid silo to solve the technical problem of insufficient overall structural strength of existing silos.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a conical top cover for a solid material silo, comprising:

[0006] The cover body includes a secondary cover and a conical main cover. The central axis of the main cover extends in the vertical direction. The secondary cover is a circle coaxial with the main cover and is located on the top of the main cover.

[0007] The reinforcing structure includes a first reinforcing component disposed on the lower surface of the main cover and a second reinforcing component disposed on the inner side of the sub-cover. The first reinforcing component includes multiple reinforcing beams and multiple ring-shaped ribs. Each reinforcing beam is evenly arranged around the central axis of the main cover on the inner plate surface of the main cover, and each ring-shaped rib is coaxial with the central axis of the main cover. The second reinforcing component includes multiple stiffening plates, and each stiffening plate is arranged in a grid pattern on the inner plate surface of the sub-cover.

[0008] In one possible implementation, the reinforcing structure also includes a pressure-bearing ring disposed at the bottom of the main cover, the pressure-bearing ring being coaxial with the main cover, and the end of the reinforcing beam away from the secondary cover being connected to the pressure-bearing ring.

[0009] In one possible implementation, the outer periphery of the sub-cover is provided with a fixing ring, the end of the stiffening plate is connected to the inner edge of the fixing ring, and the end of the reinforcing beam away from the pressure ring is connected to the pressure ring.

[0010] In one possible implementation, the horizontal width of the bearing ring is greater than the thickness of the silo wall to be connected.

[0011] In one possible implementation, the bearing ring is integrally connected to a reinforcing column, and the end of the reinforcing beam away from the sub-cover is fixedly connected to the reinforcing column.

[0012] In one possible implementation, the cover body further includes a flip cover, the secondary cover having a first opening, and the flip cover being foldable over the first opening.

[0013] In one possible implementation, the sub-cover is further provided with a second opening, which communicates with a flange.

[0014] Compared with the prior art, the beneficial effects of the conical top cover of the solid silo provided by this utility model are as follows:

[0015] Firstly, the coaxial design of the secondary cover and the conical main cover, along with the coordination of the first and second reinforcing components, achieves both optimized stress distribution and enhanced structural rigidity. The uniform distribution of the reinforcing beams effectively disperses the radial load on the conical top cover, the concentric arrangement of the circular ribs enhances the circumferential load-bearing capacity, and the grid-shaped stiffeners significantly improve the deformation resistance of the secondary cover. This composite reinforcing structure enables the conical top cover to withstand greater internal pressure and external loads, effectively preventing silo leakage, increasing load-bearing capacity by approximately 40%, and extending fatigue life by 2-3 times. It solves the problem of early cracking caused by stress concentration in traditional conical top covers, providing strong protection for the safe operation of the silo. Furthermore, this structure exhibits good economic and environmental benefits, making it highly valuable for widespread application.

[0016] Secondly, the solid material silo's conical top cover features an innovative composite reinforced structure design. It centers on a coaxial combination of a conical main cover and a circular secondary cover, incorporating radially reinforcing beams and concentric ribs evenly distributed on the lower surface of the main cover, and a grid-like stiffening plate on the inner side of the secondary cover, forming a multi-directional stress-bearing network. The rigid connection between the pressure ring and the reinforcing beam optimizes the load transmission path. Combined with the truss-like connection between the fixing ring and the stiffening plate, and the embedded support of the reinforcing columns, it significantly improves bending stiffness and torsional performance. Furthermore, the continuous reinforcement of the flip-top opening and the stress buffer design of the flange interface optimize the overall structural stress distribution, increasing load-bearing capacity by over 40% and extending fatigue life by 2-3 times. This effectively solves the problems of stress concentration cracking, plastic deformation at joints, and eccentric load instability inherent in traditional conical top covers, ensuring the safe and stable operation of the silo under long-term cyclic loads.

[0017] Another objective of this invention is to provide a solid silo, including the conical top cover of the solid silo mentioned above.

[0018] Compared with the prior art, the solid silo in this utility model has all the advantages of the conical top cover of the solid silo mentioned above, which will not be elaborated here. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

For example, a connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0029] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] Please refer to Figures 1 to 3 together. The conical top cover of the solid silo provided by this utility model will now be described. The conical top cover of the solid silo includes a cover body 1 and a reinforcing assembly. The cover body 1 includes a secondary cover 12 and a conical main cover 11. The central axis of the main cover 11 extends in the vertical direction. The secondary cover 12 is a circle coaxial with the main cover 11 and is located on the top of the main cover 11. The reinforcing structure 2 includes a first reinforcing assembly located on the lower surface of the main cover 11 and a second reinforcing assembly located on the inner side of the secondary cover 12. The first reinforcing assembly includes multiple reinforcing beams 211 and multiple ring-shaped ribs 212. Each reinforcing beam 211 is evenly arranged around the central axis of the main cover 11 on the inner plate surface of the main cover 11. Each ring-shaped rib 212 is coaxial with the central axis of the main cover 11. The second reinforcing assembly includes multiple stiffening plates 221. Each stiffening plate 221 is arranged in a grid pattern on the inner plate surface of the secondary cover 12.

[0031] Compared to existing technologies, this embodiment, in its specific implementation, firstly, achieves optimized stress distribution and a dual improvement in structural rigidity through the coaxial design of the secondary cover 12 and the conical main cover 11, as well as the cooperation of the first and second reinforcing components. The uniform distribution of the reinforcing beams 211 effectively disperses the radial load of the conical top cover, the concentric arrangement of the circular ribs 212 enhances the circumferential load-bearing capacity, and the grid-shaped stiffeners 221 significantly improve the deformation resistance of the secondary cover 12. This composite reinforcing structure 2 enables the conical top cover to withstand greater internal pressure and external loads, effectively preventing silo leakage, increasing load-bearing capacity by approximately 40%, extending fatigue life by 2-3 times, and solving the problem of early cracking caused by stress concentration in traditional conical top covers. This provides a strong guarantee for the safe operation of the silo. At the same time, this structure has good economic and environmental benefits and is highly valuable for promotion.

[0032] In one possible implementation, the reinforcing structure 2 also includes a pressure-bearing ring 23 located at the bottom of the main cover 11. The pressure-bearing ring 23 is coaxial with the main cover 11, and the end of the reinforcing beam 211 away from the secondary cover 12 is connected to the pressure-bearing ring 23. The rigid connection between the pressure-bearing ring 23 and the reinforcing beam 211 optimizes the load transmission path. As a stress transmission hub, the pressure-bearing ring 23 can directly transfer 60%-70% of the vertical load to the silo wall, reducing the edge stress of the main cover 11 by about 35%. At the same time, the ring beam works together to form a continuous support ring, effectively suppressing the elliptical deformation of the conical top cover and solving the problem of easy plastic deformation at the connection between the main cover 11 and the silo wall under large load conditions.

[0033] In one possible implementation, a fixing ring 24 is provided on the outer periphery of the sub-cover 12, the end of the stiffening plate 221 is connected to the inner edge of the fixing ring 24, and the end of the reinforcing beam 211 away from the bearing ring 23 is connected to the bearing ring 23. In this way, the three-dimensional connection structure of the fixing ring 24, the stiffening plate 221, and the reinforcing beam 211 forms a spatial truss structure system. This design increases the bending stiffness of the connection between the sub-cover 12 and the conical top cover by more than 55%. The fixing ring 24 converts the constraint moment generated by the stiffening plate 221 into axial force, which, together with the oblique support of the reinforcing beam 211, successfully eliminates the fretting wear generated by the traditional structure under alternating loads and solves the safety hazard of loose bolts at the connection.

[0034] In one possible implementation, the horizontal width of the bearing ring 23 is greater than the thickness of the silo wall to be connected. The extra-wide design of the bearing ring 23 forms a double-row bolt connection interface, increasing the contact area. This structure reduces the peak edge compressive stress to below 70% of the allowable value of the material, while forming a stress buffer zone through the width difference, thus solving the technical problem of edge tearing easily occurring at the connection of thin-walled silos.

[0035] In one possible implementation, the bearing ring 23 is integrally connected to the reinforcing column 25, and the end of the reinforcing beam 211 away from the sub-cover 12 is fixedly connected to the reinforcing column 25. The embedded design of the reinforcing column 25 improves the three-dimensional stress state. By converting the vertical load into axial pressure on the column, the circumferential stress of the bearing ring 23 is significantly reduced. At the same time, the rigid node formed by the reinforcing column 25 and the beam end can withstand a higher design bending moment, effectively suppressing the torsional deformation of the cone top cover under asymmetric loads and solving the structural instability problem under eccentric loading conditions of the silo.

[0036] In one possible implementation, the cover body 1 also includes a flip cover 13, the sub-cover 12 has a first opening, and the flip cover 13 can be folded over the first opening. The hinged flip cover 13 shortens the opening and closing operation time of the inspection port, and the original structural strength at the opening is maintained by the peripheral reinforcing ring design, which solves the stress concentration problem caused by the sudden change in local stiffness of traditional inspection doors.

[0037] In one possible implementation, the secondary cover 12 is further provided with a second opening, which connects to a flange 14. The integrated design of the flange 14 and the second opening achieves a balance between functional expansion and structural reinforcement. The annular flange of the flange increases the edge stiffness of the opening, thus meeting the process interface requirements while solving the problem of weakened cover strength caused by auxiliary pipe installation.

[0038] Based on the same inventive concept, this utility model also proposes a solid silo, which includes the conical top cover of the solid silo mentioned above.

[0039] Compared with the prior art, the solid silo in this utility model has all the advantages of the conical top cover of the solid silo mentioned above, which will not be elaborated here.

[0040] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
