Reinforced concrete ground silo with large steel funnel

Abstract

This invention discloses a reinforced concrete silo with a large steel funnel, comprising a silo body, a silo cavity including a lower silo, an upper silo, an outer supporting annular frame beam, a silo top plate, a first steel funnel, filler material, and a second steel funnel. By setting the first steel funnel inside the silo body with the silo cavity, and adding filler material to the outer side of the first steel funnel and the inner sidewall of the silo cavity, the filler material is currently the commonly used concrete, so that the first steel funnel part is subjected to concrete compression instead of the annular steel plate being subjected to bending. After the size of the lower half of the steel funnel is reduced, the buckling deformation of the annular steel plate will be greatly reduced, effectively solving the problem that steel unloading hoppers often have large buckling deformation due to excessive size and weak rigidity, which poses a safety hazard.

Description

Technical Field

[0001] This invention relates to the field of industrial silo structure technology, and in particular to a reinforced concrete ground-mounted silo with a large steel hopper. Background Technology

[0002] In traditional large-diameter reinforced concrete silo structures, due to requirements such as process volume, unloading height, and connection methods between the unloading port and conveying equipment, large-diameter reinforced concrete silos are usually equipped with steel unloading hoppers that are relatively large in diameter and deep. The common practice for steel unloading hoppers is to use annular steel plates with several circumferentially arranged stiffening ribs, and then the steel unloading hopper is connected to a ring beam on the reinforced concrete silo wall through circumferential steel plate anchors. The entire steel unloading hopper is suspended on the reinforced concrete ring beam supported by the vertical wall of the silo.

[0003] Steel unloading hoppers, due to their excessive size and relatively weak rigidity, often exhibit significant buckling deformation under the weight of the material. This apparent buckling deformation can easily give the illusion of structural insecurity and danger. If the deformation continues to increase, the structure may even pose a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide a reinforced concrete ground-mounted silo with a large steel hopper, in order to solve the problem that steel unloading hoppers often have large buckling deformation due to their large size and weak rigidity, which poses a safety hazard.

[0005] The technical solution of the present invention: A reinforced concrete ground-mounted silo with a large steel funnel, comprising a silo body, wherein an inner cavity is formed inside the silo body extending vertically, and includes a lower silo and an upper silo, wherein the upper silo is located above the lower silo, and the two are connected and fixed by an external support annular frame beam.

[0006] A silo top plate, wherein the silo top plate is disposed at the opening on the upper side of the inner cavity of the silo;

[0007] The first steel funnel is disposed inside the upper silo, and the end with the smaller opening area extends into the inner side of the silo. A filling material is provided between the inner side wall of the upper silo and the first steel funnel, and on the upper side of the outer supporting annular frame beam.

[0008] The second steel funnel is located at the lower opening of the first steel funnel, and the second steel funnel and the first steel funnel are fixedly connected by fixing bolts.

[0009] Furthermore, the main body of the support frame includes:

[0010] An inner support column is provided inside the lower silo.

[0011] An inner supporting annular frame beam is provided inside the outer supporting annular frame beam, and the inner annular sidewall is connected to the outer sidewall of the first steel funnel.

[0012] Furthermore, a reinforcing support rod is provided between the inner supporting annular frame beam and the outer supporting annular frame beam.

[0013] Furthermore, a ring-shaped steel bar is provided between the outer sidewall of the upper opening of the first steel funnel and the inner sidewall of the upper silo.

[0014] Furthermore, the first steel funnel and the inner supporting annular frame beam are secured by multiple sets of embedded parts.

[0015] Furthermore, a reinforcing plate is provided between the lower end face of the inner supporting annular frame beam and the outer sidewall of the first steel funnel.

[0016] Furthermore, an unloading platform is provided on the inner side wall of the lower silo, located below the second steel hopper.

[0017] The beneficial effects of this invention compared to the prior art are as follows: By setting a first steel funnel inside the silo body with a silo cavity, and adding filling material to the outer side of the first steel funnel and the inner side wall of the silo cavity, the filling material is concrete, which is commonly used at present. This makes the first steel funnel part subjected to concrete compression instead of the annular steel plate being subjected to bending. After the size of the lower part of the steel funnel is reduced, the buckling deformation of the annular steel plate will be greatly reduced. This effectively solves the problem that steel unloading hoppers often have large buckling deformation due to their large size and weak rigidity, which poses a safety hazard.

[0026] See Figure 1-5The present invention discloses a reinforced concrete silo with a large steel funnel, comprising a silo body, wherein a silo cavity 20 is formed through the inner side of the silo body, and includes a lower silo 1 and an upper silo 2, wherein the upper silo 2 is located above the lower silo 1 and the two are connected and fixed by an outer supporting annular frame beam 10; a first steel funnel 5, wherein the first steel funnel 5 is disposed inside the upper silo 2, and the end with the smaller opening area extends to the inner side of the lower silo 1, and a filler 3 is provided between the inner side wall of the upper silo 2 and the first steel funnel 5, and above the outer supporting annular frame beam 10; and a support frame body, wherein the support frame body is disposed inside the lower silo 1, and the upper end face is connected to the outer side wall of the first steel funnel 5. In use, the formed silo body creates a silo cavity 20 for storing the required materials. An external supporting annular frame beam 10 divides the silo body into a lower silo 1 and an upper silo 2, and the resulting silo cavity 20 is similarly divided into an upper silo cavity and a lower silo cavity. Furthermore, a filler 3 is provided between the inner wall of the upper silo 2's inner cavity and the first steel funnel 5, located above the external supporting annular frame beam 10. The filler 3 increases the load-bearing capacity of the first steel funnel 5 at this location, preventing plastic deformation of the first steel funnel 5 due to prolonged material storage, which would affect its use. Simultaneously, the upper opening of the inner cavity of the upper silo 2 is sealed by a silo top plate 4. (See reference...) Figure 5 In this design, a first steel funnel 5 serves as a guide for material discharge, transforming the inner cavity 20 of the silo from a constant cross-sectional area (Cavity 1 201) to a gradually decreasing cross-sectional area (Cavity 200 200). The force Pn is illustrated in the diagram, and the filling material 3 provides support for the first steel funnel 5. A second steel funnel 8 increases the discharge length of the first steel funnel 5, enhancing the discharge efficiency. The overall cross-sectional area of ​​the inner cavity of the steel funnels gradually decreases from top to bottom. When the second steel funnel 8 and the first steel funnel 5 are connected, the inner side of the upper opening of the second steel funnel 8 and the outer sidewall of the lower opening of the first steel funnel 5 are fitted together. The connection between the second steel funnel 8 and the first steel funnel 5 is secured by fixing bolts 80.

[0027] Specifically, it also includes a support frame body, which is located inside the lower silo 1, and its upper end face is connected to the outer sidewall of the first steel funnel 5. The support frame body includes an inner support column 11, which is located inside the lower silo 1; and an inner support annular frame beam 7, which is located inside the outer support annular frame beam 10, and its annular inner sidewall is connected to the outer sidewall of the first steel funnel 5. The formed support frame body further enhances the support for the first steel funnel 5 and the filling material 3. Utilizing the inner support column 11 as the main support body, and through the connection between the inner support annular frame beam 7 and the first steel funnel 5, it provides support and restraint to the lower side with a smaller opening area. Furthermore, a reinforcing support rod 60 is provided between the inner support annular frame beam 7 and the outer support annular frame beam 10. The reinforcing support rod 60 enhances the integrity of the support ring formed by the inner and outer sides, increasing stability. A side plate 61 is provided between the two adjacent sets of reinforcing support rods 60 to prevent the filler 3 from falling between the supporting annular frame beam 7 and the outer supporting annular frame beam 10.

[0028] Specifically, a ring-shaped reinforcing bar 31 is provided between the outer sidewall of the upper opening of the first steel funnel 5 and the inner sidewall of the upper silo 2. The ring-shaped reinforcing bar 31 and the first steel funnel 5 can be fixedly connected by welding or bolts at their contact points, and the ring-shaped reinforcing bar 31 and the inner sidewall of the silo cavity 20 can be fixedly connected by welding or bolts at their contact points. The filling material 3 can be common concrete, which is convenient to use and has a long service life. The concrete is further divided into two groups of concrete with different compositions. The filling material 3 concrete at the location where the ring-shaped reinforcing bar 31 is located is ordinary concrete 30 with a lower density, and its strength grade is the same as that of the silo body 2, which improves the connection stability at this connection point. The filling material 3 concrete located below the ring-shaped reinforcing bar 31 is lightweight aggregate concrete 300 with a higher density. Lightweight aggregate concrete has a lower elastic modulus and better deformation performance.

[0029] Specifically, the first steel funnel 5 and the inner supporting annular frame beam 7 are fixedly connected to the inner sidewall of the inner supporting annular frame beam 7 by multiple sets of pre-embedded fixing parts 51, preventing them from falling off during use. Furthermore, a reinforcing plate 81 is provided between the lower end face of the inner supporting annular frame beam 7 and the outer sidewall of the first steel funnel 5. A beam bottom pre-embedded part 52 is provided between the reinforcing plate 81 and the inner supporting annular frame beam 7 to increase the connection stability. The reinforcing plate 81 further enhances the connection stability between the two.

[0030] Specifically, an unloading platform 9 is provided on the inner side wall of the lower silo 1 and below the second steel funnel 8.

[0031] In addition to the preferred embodiments described above, the present invention has other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
