To avoid this, people have tried filling airtight granaries with protective gas to kill pests by depriving them of oxygen. However, due to the current low airtightness of granaries, the protective gas leaks, disrupting the oxygen-deficient environment and rendering the pest control ineffective. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a highly airtight grain silo, possessing the advantages of high airtightness and pest prevention. It solves the problem that currently, grain silos often harbor surviving pests, requiring insecticide spraying before sealing, which contaminates the grain. To avoid pesticide contamination, people have used protective gas to fill the airtight silo, causing pests to die from oxygen deprivation. However, current silos are not airtight enough, leading to gas leakage, disruption of the oxygen-deficient environment, and ineffective pest control.

[0005] (II) Technical Solution

[0006] To achieve the aforementioned objectives of high airtightness and pest prevention, this utility model provides the following technical solution: a high airtight grain silo, comprising a grain silo and wall components, wherein the grain silo includes walls and a floor.

[0007] The ground is covered with a ground sealing film.

[0008] The interior walls of the grain silo are fitted with multiple wall components in a tight and orderly manner. Each wall component includes a wall sealing film, and the wall sealing films on adjacent wall components are used to seal the gaps between the wall components.

[0009] The top of the internal wall components of the grain silo is also covered with a top sealing film.

[0010] The ground sealing membrane, wall components, and top sealing membrane together form a highly airtight space inside the grain silo for storing grain.

[0011] Preferably, the wall component further includes a first steel plate, a rigid insulation board, and a second steel plate that are sequentially bonded together, and the wall sealing film covers the outer surface of the first steel plate, with at least one periphery of the wall sealing film extending beyond the boundary of the first steel plate to form a covered area.

[0012] Preferably, the wall component is provided with drilling points at its four corners.

[0013] Preferably, the distance between the punching point and the boundary of the first steel plate is less than the distance of the wall sealing film extending beyond the boundary of the first steel plate.

[0014] Preferably, a pin is provided on one side of the rigid insulation board, and a groove is provided on the other side of the rigid insulation board. When the wall components are spliced ​​in parallel, the pin is embedded in the groove of the rigid insulation board of the adjacent wall component.

[0018] Preferably, the grain silo is also equipped with a ventilation device, which is used to inject protective gas, cold air or constant temperature gas into the highly airtight space inside the grain silo.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, this utility model provides a highly airtight grain silo, which has the following beneficial effects:

[0021] This type of high-airtightness grain silo utilizes the coordinated use of silo and wall components. During the airtightness installation, the wall components are vertically, tightly, and arranged in a fixed pattern on the silo walls. Ground sealing films and top sealing films cover the ground and top of the silo, respectively, creating a highly airtight environment within the entire silo. Rigid insulation boards are naturally foamed and bonded to the first and second steel plates on both sides. The composite film is then adhered to the surface of the first steel plate using hot air welding technology. When assembling the wall components in parallel, expanding foam is first applied to the surface of the second steel plate of one wall component, which is then adhered to the wall. After adhesion, holes are drilled at four designated points, and expansion bolts are used to completely secure the wall component to the wall. The second wall component is then installed, similarly applying expanding foam and inserting the groove into the pin of the first wall component, securing it with expansion bolts. Finally, the side-splicing film of the first wall component is placed over the composite film of the second wall component, completely covering the perforated points, and then bonded together using hot air welding technology. Next, the ground sealing film is adhered to the ground, and its four edges are welded to the bottom of the wall component using hot air welding technology, forming a seal between the ground and the wall component. Grain can then be placed inside. After the grain is filled, a top sealing film is placed on top of the grain, and then protective gas is injected into the grain to expel the original air, creating a pressure-deficient environment that kills pests, and the protective gas is not easily leaked. This achieves high airtightness and pest prevention. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-7 A highly airtight grain silo 1 includes a grain silo 1 and wall components 2. The grain silo 1 includes walls 11 and a floor 12. The highly airtight grain silo 1 ensures that grain is not affected by external air, humidity, pests, or other factors during storage, maintaining grain quality and extending storage life. The walls 11 form the external enclosure structure of the grain silo 1, preventing external environmental factors such as wind, rain, snow, and sunlight from adversely affecting the interior of the grain silo 1. The floor 12 supports all the grain and wall components 2 inside the grain silo 1, while preventing groundwater or moisture from intruding into the grain silo 1. Multiple wall components 2 are tightly and orderly arranged and attached to the walls 11 inside the grain silo 1. Each wall component 2 includes a wall sealing film 21, which seals the gaps between adjacent wall components 2. The floor 12 is covered with a floor sealing film, which seals the gaps between the wall components 2 and the floor 12. The inner wall components 2 of the grain silo 1 are also covered with a top sealing film 4. When the grain silo 1 is filled with grain, only the top of the grain is not sealed. At this time, a top sealing film 4 needs to be laid on top of the wall components 2 to seal the space at the top of the wall components 2. The grain is stored in a highly airtight space formed between the ground sealing film 12, the wall components 2 and the top sealing film 4.

[0032] The wall component 2 also includes a first steel plate 22, a rigid insulation board 23, and a second steel plate 24 that are sequentially bonded together. A wall sealing film 21 covers the outer surface of the first steel plate 22. The rigid insulation board 23, made of foamed materials such as polyurethane, EPS, or XPS, is sandwiched between the first steel plate 22 and the second steel plate 24. The rigid insulation board 23 bonds to the first steel plate 22 and the second steel plate 24 through its own natural foaming process and, after a certain period of hardening, acquires a certain strength and rigidity. The first steel plate 22 and the second steel plate 24 are made of steel plates with a thickness of 0.3-0.6 mm. The presence of the first steel plate 22 and the second steel plate 24 enhances the overall strength and rigidity of the wall component 2, giving it a longer service life and better compressive strength. The wall sealing film 21, the floor sealing film 12, and the top sealing film 4 are all made of PVC roll material. These materials offer excellent airtightness and weldability. When the wall components 2 are installed in parallel, the wall sealing film 21 extends beyond the boundary of the first steel plate 22 to form a covering area. This covering area can be applied to the joint between adjacent wall components 2 using hot air welding technology, completely sealing the joint and improving indoor airtightness. Similarly, the floor sealing film 12 and the top sealing film 4 can be applied to the bottom and top of the wall components 2 using hot air welding technology. Furthermore, the PVC roll material exhibits very low shrinkage and deformation due to thermal expansion and contraction, preventing loosening and detachment even after prolonged use.

[0033] Perforation points 25 are provided at the four corners of the wall sealing film 21. The distance between the perforation points 25 and the boundary of the first steel plate 22 is less than the distance of the wall sealing film 21 extending beyond the boundary of the first steel plate 22. During the installation of the wall component 2 onto the wall surface 11, expanding foam is first sprayed onto the surface of the second steel plate 24, and then the entire wall component 2 is adhered to the wall surface 11 or the ground surface 12. After drilling the perforation points 25, expansion bolts are installed to further enhance the connection strength between the wall component 2 and the wall surface 11 or the ground surface 12. After drilling and installing the expansion bolts, there will still be some airtightness issues at the perforation points. Therefore, when the wall component 2 is installed parallel to the ground surface 12 sealing film or perpendicular to the top sealing film 4, the area of ​​the wall sealing film 21 extending beyond the first steel plate 22 can be covered by hot air welding to cover the perforation points 25, thereby preventing air leakage and solving the airtightness problem. The same applies to the ground surface 12 sealing film.

[0034] One side of the rigid insulation board 23 is provided with a pin 232, and the other side is provided with a groove 231. When the wall components 2 are spliced ​​in parallel, the pin 232 is inserted into the groove 231 of the rigid insulation board 23 of the adjacent wall component 2. During the splicing of the wall components 2, due to the large volume and area of ​​the wall components 2, precise installation is difficult. Therefore, the pin 232 and groove 231 are used to accurately splice the wall components 2 in pairs. In addition, the use of the pin 232 and groove 231 can increase the integrity and continuity between all wall components 2, and improve the overall strength of the wall components 2. Furthermore, the use of the pin 232 and groove 231 can improve airtightness.

[0035] The first steel plate 22 and the second steel plate 24 form an edging 221 on the side of the rigid insulation board 23. The edging 221 of the first steel plate 22 and the second steel plate 24 protects the integrity of the internal rigid insulation board 23. Furthermore, the edging 221 improves the three-dimensionality of the entire wall component 2, makes installation more precise, and ensures tighter connections between wall components 2, thus enhancing airtightness. In addition, when a large amount of grain is placed inside the grain silo 1, the compressive strength of the wall component 2 also increases, preventing cracking and misalignment of the wall component 2, which could compromise the internal airtight environment.

[0036] The lowest wall component 2, closest to the ground, is fixed to the wall surface 11. The periphery of the ground sealing film 3 is turned up beyond the ground surface 12 and welded to the outer side of the bottom of the wall component 2. The ground sealing film 12 is sealed with hot air welding technology to seal the gap between the ground surface 12 and the wall component 2 using the same covering method.

[0037] A double-groove tube 6 is fixed to the top of the wall component 2, serving as a connector between the top sealing membrane 4 and the wall component 2. The top of the double-groove tube 6 is bonded with butyl rubber in the middle, welded with welding ropes on both sides, and finally sealed with sealant on the outside. A flexible rubber tube 61 presses against the top sealing membrane 4 and fixes it within the groove of the double-groove tube 6 for secure sealing. The double-groove tube 6 effectively provides a double seal, resulting in a higher sealing effect than a single-groove tube.

[0038] The grain silo 1 is also equipped with a ventilation device 5, which is installed on the wall component 2 and sealed at the contact point with the wall component 2. The ventilation device 5 is used to inject protective gas, cold air, or constant temperature gas into the highly airtight space inside the grain silo 1. After the grain is filled, a top sealing film 4 needs to be placed on top of the grain, and then protective gas is injected into the grain to expel the original air inside the grain, so that the internal pressure reaches a certain value, creating an oxygen-deficient environment to kill pests, and the protective gas is not easy to leak. In addition, when the internal temperature is too high due to the heat generated by the accumulation of grain, cold air can be injected to cool the internal environment and prevent fire. When the internal temperature is low and the grain is prone to freezing, constant temperature gas can be injected to maintain the internal temperature and ensure long-term storage of grain.

[0039] Working Principle: During the airtight decoration of the grain silo 1, the wall components 2 are vertically, tightly, and arranged in a fixed manner on the wall 11 of the grain silo 1. The sealing film 12 on the ground and the sealing film 4 on the top of the grain silo 1 are respectively covered by the sealing film 12 on the ground and the top of the grain silo 1. The three are tightly covered to form a highly airtight environment inside the entire grain silo 1. The rigid insulation board 23 is naturally foamed and bonded to the first steel plate 22 and the second steel plate 24 on both sides. Then, the composite film is pasted to the surface of the first steel plate 22 by hot air welding technology. When splicing the wall components 2 in parallel, firstly, foaming adhesive is applied to the surface of the second steel plate 24 of one wall component 2 and pasted to the wall 11. After pasting, holes are drilled at the four drilling points 25. After drilling, the wall component 2 is completely fixed to the wall 11 with expansion bolts. Then, the second wall component 2 is installed. In the same way, foaming adhesive is applied, and the groove 231 is inserted into the pin 232 of the first wall component 2 and fixed with expansion bolts. Finally, the side splicing film of the first wall component 2 is placed over the composite film of the second wall component 2, completely covering the perforation points 25, and then bonded together using hot air welding technology. Next, the sealing film of the ground 12 is adhered to the ground 12, and the four edges of the sealing film of the ground 12 are welded to the bottom of the wall component 2 using hot air welding technology, forming a seal between the ground 12 and the wall component 2. Grain can then be placed inside. After the grain is filled, a top sealing film 4 is placed on top of the grain, and then protective gas is injected into the grain to expel the original air inside, creating a certain pressure value and forming an oxygen-deficient environment to kill pests. Furthermore, the protective gas is not easily leaked. This achieves high airtightness and pest prevention.
