Description

Technical Field

[0001] The present invention relates to the technical field of grain storage, and particularly to a novel thermal insulation silo. Background Art

[0002] In the field of grain storage, silos, as important facilities for storing grains, have a development process closely linked to agricultural production and grain reserve requirements. Early silos were mostly simple brick or wooden structures. With the progress of industrial technology, they gradually developed into silos made of metal materials. In modern grain storage, ordinary silos are widely used in various grain depots, farms, and grain processing enterprises, undertaking short-term and long-term grain storage tasks.

[0003] For the silos in the prior art, from the perspective of mechanical technology, the operation of grain inlet and outlet mainly relies on gravity. In terms of structural principles, common ones include steel silos, which use thin steel plates as the silo wall materials and rely on their own strength to bear the weight of grains. Steel silos are relatively easy to install, but during long-term use, they are greatly affected by environmental factors.

[0004] In actual use scenarios, for example, in some areas with variable climates, due to limited structural mechanical properties, ordinary steel silos are difficult to withstand large seismic forces and typhoon loads, and are prone to silo body deformation or even collapse, resulting in grain damage. At the same time, the waterproof performance of ordinary silos is poor. During the rainy season, rainwater easily seeps into the silo, causing the grains to get damp and moldy. Moreover, many silos have poor thermal insulation performance. In seasons with large temperature changes, condensate is likely to be generated inside the silo, affecting the grain quality. In addition, the space utilization rate of traditional silos is relatively low, unable to fully meet the growing grain storage demand. Therefore, the present invention provides a novel thermal insulation silo to solve the deficiencies existing in the prior art. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a novel thermal insulation silo, which solves the problems that the silos in the prior art are difficult to withstand large external force impacts and have poor thermal insulation and waterproof performance.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A novel thermal insulation silo, comprising: a silo wall, which serves as the basis of the entire silo and is used to carry and build other structural components;

[0007] a silo top, which is located at the top of the silo wall, and its bottom is in contact with the top of the silo wall, and is used to cooperate with the silo wall.

[0008] Preferably, the silo wall includes a wall panel, a side thermal insulation layer, and a side inner lining layer. The side thermal insulation layer is arranged on the inner side of the wall panel, and the side inner lining layer is arranged on the inner side of the side thermal insulation layer.

[0009] Preferably, the material of the wall panel is galvanized steel, the material of the side insulation layer is polyurethane foam, and the side lining layer is made of reinforced concrete.

[0010] Preferably, the wall panel is a spiral ascending rolled plate structure, and the rolled plate is a five-layer lock seam structure.

[0011] Preferably, the silo top includes a top plate, a top insulation layer and a top lining layer. The top insulation layer is arranged inside the top plate, and the top lining layer is arranged inside the top insulation layer.

[0012] Preferably, the material of the top plate is galvanized steel, the material of the top insulation layer is polyurethane foam, and the top lining layer is made of reinforced concrete.

[0013] Preferably, the overall structure of the silo wall is cylindrical, and the silo top is a vault structure.

[0014] The present invention provides a new type of insulated silo, which has the following beneficial effects:

[0015] 1. By adopting an innovative structure of outer steel plate combined with inner reinforced concrete, the cylindrical wall panel and the vault design of the present invention conform to the mechanical principle, disperse the force, enable it to bear a large load, effectively resist natural disasters such as earthquakes and typhoons, and greatly improve the firmness compared with traditional steel silos. Moreover, this structure has a simple and beautiful appearance, reduces costs while ensuring strength, has a high filling rate, maximizes the use of storage space, and realizes the perfect balance between space utilization and structural strength.

[0016] 2. The overall outer steel structure of the present invention is firm and stable. The inner layer uses the spraying method to make the insulation layer and reinforced concrete, which are seamlessly connected into one body, effectively blocking rainwater penetration and having excellent waterproof performance. At the same time, a polyurethane foam sandwich layer is sprayed between the steel shell and the reinforced concrete. Utilizing its low thermal conductivity, it reduces heat transfer, reduces temperature fluctuations, avoids the generation of condensed water, maintains the dryness inside the silo, and provides a high-quality temperature and humidity environment for the stored materials.

[0017] 3. By adopting a steel structure for the outer wall of the silo, the construction is convenient, and the internal insulation and reinforced concrete production are less restricted by the weather, and the construction can be steadily promoted, greatly shortening the construction period. This enables it to be quickly built and put into use, especially suitable for areas with complex climate conditions and tight construction periods, saving time costs for project implementation.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to the attached Figure 1 - attached Figure 3, an embodiment of the present invention provides a new type of insulated silo, including: a silo wall 1, which serves as the foundation of the entire silo and is used to carry and build other structural members. Galvanized steel is selected as the material of the wall panel 11. Galvanized steel has good anti-rust performance and can effectively resist the erosion of the external environment on the silo, ensuring the stability of long-term use. The wall panel 11 is made into a spiral rising rolled plate structure, and the rolled plate is a five-layer lock seam structure. This unique structural design greatly enhances the integrity and strength of the wall panel 11, enabling it to better withstand the pressure from the internal rice. On the inner side of the wall panel 11, polyurethane foam is sprayed to form a side insulation layer 12. Polyurethane foam has excellent heat insulation performance, with a low thermal conductivity, which can effectively reduce the heat exchange inside and outside the silo, maintain the stability of the temperature inside the silo, and provide a suitable temperature environment for rice storage. Then, on the inner side of the side insulation layer 12, the steel bars are first woven into a net, and then concrete is sprayed to make the steel bar net closely combined with the side insulation layer 12, forming a side lining layer 13. The side lining layer 13 made of reinforced concrete is not only strong and durable but also can further enhance the structural strength of the silo wall 1. At the same time, the presence of steel bars improves the crack resistance of the concrete. The silo top 2 is located at the top of the silo wall 1, and its bottom fits with the top of the silo wall 1 and is used in cooperation with the silo wall 1. The silo top 2 includes a top plate 21, a top insulation layer 22, and a top lining layer 23. The top plate 21 is also made of galvanized steel, taking advantage of its anti-rust and certain strength characteristics to ensure the basic structural stability of the silo top 2. The material of the top insulation layer 22 is polyurethane foam, continuing its heat insulation advantage to reduce the heat dissipation from the silo top 2. The top lining layer 23 is made of reinforced concrete, and the manufacturing process is similar to that of the side lining layer 13 of the silo wall 1. First, the steel bar net is woven and then concrete is sprayed, so as to be closely combined with the top insulation layer 22. The overall structure of the silo wall 1 is cylindrical, and this shape is conducive to evenly dispersing the internal pressure; the silo top 2 is a vault structure, and the vault structure has excellent mechanical properties and can effectively disperse the upper load, enabling it to adapt to a larger load and having strong earthquake and typhoon resistance capabilities, being more durable than the traditional steel silo. During the actual construction process, first complete the production of the silo wall 1 according to the above steps to ensure that each layer of the structure is closely combined to form a stable load-bearing structure. Then, manufacture the silo top 2 in the same way and accurately install it on the top of the silo wall 1 to make the two closely fit, completing the construction of the entire new type of insulated silo. After the construction is completed, the silo as a whole forms a stable, insulated, and strong storage space, meeting the requirements for the long-term safe storage of rice.

[0024] Specifically, first, galvanized steel is selected as the material for making the wall panel 11. The zinc layer on the surface of the galvanized steel can effectively isolate air and moisture, prevent the steel from rusting, and ensure the stability and durability of the structure of the silo during long-term use. The galvanized steel is made into a cylindrical shape, and the wall panel 11 is formed into a spiral structure, and the rolling plate adopts a five-layer bite process. This spiral rising structural design greatly enhances the integrity of the wall panel 11, makes the connection between the parts tighter, and significantly improves the overall strength. The five-layer bite structure further strengthens the stability of the connection, effectively disperses the pressure from the internal rice, allows the silo to withstand a larger weight, and ensures that the silo wall 1 will not be easily deformed or damaged when storing a large amount of rice. After the wall panel 11 is made, polyurethane foam is sprayed on the inner side of the wall panel 11 to form a side insulation layer 12. Polyurethane foam has an extremely low thermal conductivity. After spraying, it is tightly attached to the inner side of the wall panel 11, and can form an efficient thermal insulation barrier between the inside of the silo and the external environment. This greatly reduces the heat exchange inside and outside the silo, effectively maintains the stability of the temperature inside the silo, creates suitable temperature conditions for the storage of rice, avoids the deterioration or germination of rice due to large temperature fluctuations, and ensures the quality of rice. Next, the steel bar mesh is woven on the inner side of the side insulation layer 12. The steel bar has good tensile properties. After being woven into a mesh, it can be tightly combined with the concrete during the subsequent concrete spraying process. Then the concrete is sprayed, and the concrete tightly wraps the steel mesh and the side insulation layer 12 and combines them together to form a side lining layer 13. The side lining layer 13 made of reinforced concrete has both the compressive strength of concrete and the tensile strength of steel bars, which greatly enhances the overall structural strength of the silo wall 1. At the same time, the steel bar can effectively restrain the expansion of cracks generated by concrete when it is stressed, improve the crack resistance of concrete, ensure that the silo wall 1 maintains its integrity during long-term use, and will not affect the overall performance due to the development of small cracks. Similarly, the manufacture of the silo roof 2 is also carried out in the same way. The top plate 21 is made of galvanized steel to ensure the basic structural stability and rust resistance of the silo roof 2. The top insulation layer 22 is made of polyurethane foam to reduce the heat loss from the silo roof 2 and further maintain the stability of the temperature in the silo. The top lining layer 23 is made of reinforced concrete. The manufacturing process is similar to that of the side lining layer 13 of the silo wall 1. The steel mesh is first woven and then concrete is sprayed, so that it is tightly combined with the top insulation layer 22. The silo roof 2 adopts an arch structure, which has a natural advantage in mechanical properties. It can evenly distribute the load borne by the upper part to the silo wall 1 along the curved surface of the arch, so that it can adapt to larger loads. Moreover, the spatial form of the arch structure enables it to better resist horizontal and vertical forces when facing natural disasters such as earthquakes and typhoons. It has strong earthquake and typhoon resistance. Compared with traditional steel silos, the silo roof 2 structure of the new insulated silo is more sturdy and durable, which effectively extends the service life of the silo and ensures the safety of rice storage.

[0025] Working principle: First, the wall panel 11 is made into a cylindrical shape using galvanized steel, and the wall panel 11 is formed into a helically rising structure. Then, the side insulation layer 12 is sprayed on the inner side of the wall panel 11, closely attached to the inner side of the wall panel 11. Then, steel bars are woven into a net, and then concrete is sprayed to combine the steel bar net with one side of the side insulation layer 12, so that the wall panel 11, the side insulation layer 12, and the side lining layer 13 form an integral silo wall 1. Similarly, the silo top 2 is manufactured in the same way, with better waterproof performance, good structural mechanical properties, capable of adapting to larger loads, and having strong earthquake and typhoon resistance capabilities, being more durable than traditional steel silos.
