Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and in particular to a pressure-reducing steel plate silo. Background Technology

[0002] Steel silos are storage containers made of steel plates riveted, welded, or assembled. Originally, they referred to the silo body of a steel warehouse, but can also refer to small steel silos. They have a history of over 100 years and are widely used in China. Steel silos have a wide range of applications and can be used to store various materials such as grain, feed, and flour. They occupy a very important position in material storage and are widely used in practice.

[0003] However, existing steel silos lack internal pressure-reducing structures, making it easy for materials to accumulate upon entry. Additionally, the materials at the bottom of the silos are subjected to significant pressure, posing a risk of arching. Utility Model Content

[0004] To reduce the risk of material arching inside steel silos, this utility model provides a pressure-reducing steel silo.

[0005] This utility model provides a pressure-reducing steel plate silo, which adopts the following technical solution:

[0006] A pressure-reducing steel plate silo includes a silo, a silo top, and a pressure-reducing cone bottom. The silo top is fixedly connected to the top of the silo, and the pressure-reducing cone bottom is fixedly connected to the bottom of the silo. After the silo, silo top, and pressure-reducing cone bottom are connected, an internal accommodating space is formed. A support frame is provided inside the pressure-reducing cone bottom, and a pressure-reducing component is fixedly connected to the support frame.

[0007] By adopting the above technical solution, after the silo and the pressure relief cone bottom are filled with materials, the materials in the silo will squeeze the materials in the lower pressure relief cone bottom. Under the action of pressure, it is easy to form arches, which will affect the quality of material storage. By setting pressure relief components inside, the incoming materials are evenly dispersed to the surrounding area of ​​the silo, reducing the risk of arching of materials in the pressure relief cone bottom.

[0008] Furthermore, the pressure-reducing component is cone-shaped, and its interior is hollow, with its diameter gradually decreasing from the end near the support frame to the end away from the support frame.

[0009] Furthermore, the axis of the pressure-reducing component is aligned with the axis of the silo.

[0010] Furthermore, a ring beam is fixedly connected to the upper part of the pressure-reducing cone bottom, and the pressure-reducing cone bottom is connected to the silo through the ring beam.

[0011] Furthermore, the support frame includes a main support and a secondary support. The main support is located at the bottom of the secondary support, and the upper surface of the main support is in contact with the lower surface of the secondary support. Both the main support and the secondary support are fixedly connected to the ring beam, and the projections of the center lines of the main support and the secondary support are not on a straight line.

[0012] Furthermore, both the main support and the secondary support are provided with multiple through holes, and the bottom of the pressure-reducing component is provided with multiple threaded holes that are adapted to the position. The pressure-reducing component is fixed to the main support and the secondary support by bolts.

[0013] Furthermore, the support frame includes multiple support rods and mounting rings. The support rods are arranged in a circumferential array around the mounting rings. One end of each support rod is fixedly connected to the mounting ring, and the other end of each support rod is fixedly connected to a ring beam. The mounting ring has an internal mounting groove with a diameter larger than the diameter of the bottom of the pressure-reducing component.

[0014] Furthermore, the mounting ring is provided with multiple through holes, and the bottom of the pressure reducing component is provided with multiple threaded holes that are adapted to the position. The pressure reducing component is fixed in the mounting groove inside the mounting ring by bolts.

[0015] Furthermore, the top of the silo roof is provided with at least one material inlet, and the bottom of the pressure-reducing cone is provided with a material outlet.

[0016] Furthermore, the bottom of the ring beam is provided with at least three support legs, which are fixedly connected to the ring beam.

[0017] In summary, this utility model has at least one of the following beneficial technical effects:

[0018] 1. By setting a pressure-reducing component and making it conical, after the silo and the bottom of the pressure-reducing cone are filled with material, the material in the silo will squeeze the material in the bottom of the pressure-reducing cone. Under the action of pressure, it is easy to form an arch. The pressure-reducing component makes the incoming material evenly dispersed to the sides of the silo and reduces some of the pressure on the material in the middle part of the bottom of the pressure-reducing cone, thus reducing the risk of arching of the material in the bottom of the pressure-reducing cone.

[0019] 2. The pressure-reducing component is fixed by multiple support rods and mounting rings. The mounting groove in the mounting ring can limit the pressure-reducing component, making installation easier and reducing the compressive force on the bolts, thus extending their service life.

Detailed Implementation

[0028] The technical solutions of this utility model are clearly and completely described below through specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The following combination Figures 1-7 The present invention will be described in further detail below.

[0030] Example 1

[0031] This embodiment discloses a pressure-reducing steel plate silo, referring to... Figures 1-7The system includes a silo 200 for holding materials, a silo top 100, a pressure-reducing cone bottom 300, and a pressure-reducing component 400 for dispersing materials and reducing pressure on the materials at the bottom. The silo top 100 is fixedly connected to the top of the silo 200, and the pressure-reducing cone bottom 300 is fixedly connected to the bottom of the silo 200. After the silo 200, silo top 100, and pressure-reducing cone bottom 300 are connected, an internal storage space is formed. Materials are stored in the storage space. In use, materials can be added to the top of the silo top 100, and materials can be removed from the bottom of the pressure-reducing cone bottom 300. The pressure-reducing component 400 can withstand the pressure of the materials above, reduce the pressure on the materials inside the pressure-reducing cone bottom 300, and reduce the risk of material arching.

[0032] Reference Figures 1-3 The silo 200 is cylindrical, and the silo top 100 and the pressure-reducing cone bottom 300 are both conical. The pressure-reducing cone bottom 300 is provided with a support frame 310 inside, and the pressure-reducing component 400 is fixedly connected to the support frame 310. The top of the silo top 100 is provided with at least one material inlet 110, and the bottom of the pressure-reducing cone bottom 300 is provided with a material outlet 320.

[0033] Reference Figure 3 In this embodiment, the pressure-reducing component 400 is cone-shaped and hollow inside. The diameter of the pressure-reducing component 400 gradually decreases from the end near the support frame 310 to the end away from the support frame 310. The axis of the pressure-reducing component 400 is on the same straight line as the axis of the silo 200. A ring beam 330 is fixedly connected to the upper part of the pressure-reducing cone bottom 300. The pressure-reducing cone bottom 300 is connected to the silo 200 through the ring beam 330. At least three support legs 340 are provided at the bottom of the ring beam 330, and the support legs 340 are fixedly connected to the ring beam 330.

[0034] In this way, the pressure reducing component 400 can evenly disperse the material to the surrounding area when adding material, reducing the probability of material accumulation and arching. The ring beam 330 can provide support and support the entire device through the support legs 340.

[0035] Reference Figures 4-6 In this embodiment, the support frame 310 includes a main support 311 and a secondary support 312. The main support 311 is disposed at the bottom of the secondary support 312. The upper surface of the main support 311 is in contact with the lower surface of the secondary support 312. The main support 311 and the secondary support 312 are both fixedly connected to the ring beam 330. The projections of the center lines of the main support 311 and the secondary support 312 are not on a straight line.

[0036] Both the main support 311 and the auxiliary support 312 are provided with multiple through holes 313, and the pressure reducing component 400 is provided with multiple threaded holes 410 at the bottom of the component. The pressure reducing component 400 is fixed to the main support 311 and the auxiliary support 312 by bolts.

[0037] Thus, the main support 311 and the secondary support 312 can be bolted on. The main support 311 and the secondary support 312 work together to ensure strength, structural stability, and sufficient load-bearing capacity. The pressure-reducing component 400 is easy to install and quick to disassemble and maintain.

[0038] Example 2

[0039] The difference between this embodiment and Embodiment 1 is that it provides a different structure for the support frame 310, as shown in the reference. Figure 7 The support frame 310 includes multiple support rods 314 and a mounting ring 315. The support rods 314 are arranged in a circumferential array around the mounting ring 315. One end of the support rod 314 is fixedly connected to the mounting ring 315, and the other end of the support rod 314 is fixedly connected to the ring beam 330. The mounting ring 315 has a mounting groove 316 inside. The mounting groove 316 is a circular groove, and the diameter of the mounting groove 316 is larger than the diameter of the bottom of the pressure reducing member 400. Preferably, the mounting groove 316 is slightly larger than the diameter of the pressure reducing member 400, so that the pressure reducing member 400 can be easily installed into the mounting groove 316 without moving. The mounting ring 315 has multiple through holes 313, and the bottom of the pressure reducing member 400 has multiple threaded holes 410 that are adapted to the position. The pressure reducing member 400 is fixed in the mounting groove 316 inside the mounting ring 315 by bolts.

[0040] Thus, the support rod 314 and the ring beam 330 can be connected by bolts or by welding. The mounting groove 316 can limit the pressure relief component 400, making installation easier and reducing the compressive force on the bolts, thus extending their service life.

[0041] The implementation principle of the above embodiments is as follows:

[0042] Material is added into the inlet at the top of the silo 100. After addition, the pressure reducing component 400 can evenly disperse the added material to the surrounding area, reducing the probability of material accumulation and arching. The ring beam 330 can provide support, and the entire device is supported by the support legs 340. The pressure reducing component 400 can bear part of the pressure of the material above, reducing the pressure on the material in the bottom of the pressure reducing cone 300 and reducing the risk of material arching.

[0043] The main support 311 and the secondary support 312 can be bolted together. The main support 311 and the secondary support 312 work together to ensure strength, structural stability, and sufficient load-bearing capacity. The pressure-reducing component 400 is easy to install and quick to disassemble and maintain.

[0044] In another embodiment of the support frame 310, the support rod 314 and the ring beam 330 can be connected by bolts or by welding. The mounting groove 316 can limit the pressure relief component 400, making installation easier and the bolts can be subjected to less compressive force, thus extending their service life.

[0045] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
