[0029] The present application will be further described in detail below in combination with the drawings and specific embodiments:

[0030] Embodiment 1: The present embodiment aims to provide a double-layer self-breathing heat-insulating shallow circular warehouse, which is mainly used for ventilating and drying the interior of the shallow circular warehouse. In view of the problems of complex ventilation structure, high operation difficulty, high cost and low ventilation efficiency of the current shallow circular warehouse, the present embodiment provides a double-layer self-breathing heat-insulating shallow circular warehouse.

[0031] As Figure 1 shown in Fig. 1, a double-layer self-breathing heat-insulating shallow circular warehouse includes a warehouse body, an inner support cover, an outer protective cover, a side heat pipe, an inner ring exhaust pipe, a gas increasing pipe and a supercharging assembly. In the present embodiment, a double-layer structure is arranged on the warehouse body, and a self-breathing structure is arranged inside. The double-layer structure is arranged in the top area, and the self-breathing structure is arranged in the warehouse. In principle, the gas is increased from the outside to the inside, and the generated heat is discharged to the double-layer structure. The inner support cover is used to isolate the heat, and the outer protective cover is used to establish an outer protective structure.

[0032] In the specific structure, the embodiment is provided with an outer platform 2 at the upper part of the silo body 1, the inner support cover 3 is fixed at the upper part of the silo body 1, and the outer protective cover 4 is arranged on the outer platform 2 and fixed at the outer side of the upper part of the silo body 1. The fixing of the inner support cover is the prior art, which can be fixed on the upper end face of the silo body 1 and assembled by bolts. In the fixing structure of the outer protective cover, the bottom is arranged on the outer platform, and the original outer platform is used to provide support, so as to reduce the load on the sidewall of the silo body 1.

[0033] The upper parts of the inner support cover 3 and the outer protective cover 4 are both conical structures. The inner support cover 3 is directly arranged and fixed at the top area of the flat silo. When the outer protective cover 4 is fixed, the outer protective cover is lifted and arranged on the outer platform 2. In order to ensure the overall sealing, a mounting sleeve 23 is arranged on the outer side of the silo body 1. The mounting sleeve 23 includes a plurality of arc-shaped sheet structures combined and assembled on the outer wall of the silo body 1. A plurality of clamping groove structures are arranged on the mounting sleeve. A positioning clamping block 24 is arranged on the outer protective cover. The positioning clamping block 24 is correspondingly nested in the clamping groove structure and is fixed by bolt assembly.

[0034] In the embodiment, a cavity is formed between the outer protective cover 4 and the inner support cover 3. The middle parts of the outer protective cover 4 and the inner support cover 3 are fixed on the center cylinder 5. In order to ensure the structural strength, a reinforcing rod 6 is arranged between the inner support cover 3 and the outer protective cover 4. The reinforcing rods 6 are staggered arranged in the gap. In the implementation, the reinforcing rods are first connected to form a frame structure. Only one is shown in the figure. In the specific structure, a plurality of frame structures are uniformly distributed along the circumferences of the inner support cover 3 and the outer protective cover 4.

[0035] The inner ring type exhaust pipe 8 and the air increasing pipe 9 are both suspended on the truss and the inner support cover 3. The edge heat pipe 7 is fixed on the inner wall of the silo body 1. The upper parts of the edge heat pipe 7 and the inner ring type exhaust pipe 8 extend into the cavity. In the implementation, the edge heat pipe 7 extends a fixing plate on both sides. The outer end has an inwardly extending inclined surface structure. The edge heat pipe 7 structures are uniformly distributed on the inner wall of the silo body 1. They are mainly used for heat exchange from the edge to both sides and discharge the exchanged hot air, so as to ensure the drying of the outer sidewall of the silo. Since the grain directly contacts with the outer wall, the medium is different, and it is easy to accumulate heat from the sidewall. Based on this, a plurality of edge heat pipe structures are uniformly distributed on the outer side in the embodiment, so as to realize the ventilation and heat insulation of the outer sidewall.

[0036] The air increasing pipe 9 includes a support layer 20, a gas permeable layer 21 and a fish scale layer 22. In the structure, Figures 6-7As shown, the support layer 20 is a hollow skeleton structure, the breathable layer 21 covers the outside of the support layer 20, and the fish scale layer 22 is arranged in a fish scale pattern on the outside of the breathable layer 21. There are breathable gaps between each fish scale layer 22. In this embodiment, the hollow support layer ensures that the overall internal cavity and ventilation channel are connected and has a certain supporting strength. At the same time, the breathable layer is arranged on the outside to enable gas exchange. When a high-pressure airflow is introduced into the interior, the gas can pass through the breathable layer 21 and diffuse outwards from the breathable gaps. The structure of the gas booster pipe 9 can pass through the breathable gaps under high pressure. The fish scale layer 22 is arranged downwards to prevent grain and dust from entering the interior and can deform and expand appropriately under high pressure, allowing the gas to diffuse outwards from here.

[0037] In this embodiment, heat-absorbing material is provided on the outside or inside of the inner surrounding exhaust pipe 8. The heat-absorbing material can effectively absorb heat and discharge it using pressurized airflow, thereby improving the heat absorption effect. The gas inlet pipe and the inner surrounding exhaust pipe work together to achieve controlled breathing inside the grain silo.

[0038] like Figure 2 and Figure 5 As shown, the pressurization assembly includes an inner pressurization body 17 and an outer pressurization body 16. In this embodiment, the pressurization assembly is arranged at the bottom of the silo, with the inner pressurization body 17 placed inside the outer pressurization body 16. The inner pressurization body 17 is connected to the gas booster pipe 9, and the outer pressurization pipe is connected to the side exhaust heat pipe and the inner surrounding exhaust pipe 8. Both the inner pressurization body 17 and the outer pressurization body 16 are connected to a corresponding pressurization pump. Of course, some valves, controllers, and other structures can be arranged. It is worth noting that in this embodiment, the pressurization intensity of the inner pressurization body is greater than that of the outer pressurization body. The inner pressurization body needs to diffuse the gas to the surroundings at a certain pressure (the pressure comes from the air permeable layer 21, the fish scale layer 22, and the obstruction of the surrounding grain), while the outer pressurization body is mainly used for the airflow.

[0039] In this embodiment, a booster pump is used to pressurize the internal cavities of the inner booster 17 and the outer booster 16. The inner booster 17 is connected to the booster pipe 9, one end of which is closed. An air outlet structure is provided on its side wall. By pressurizing, a booster column can be formed along the length of the booster pipe. Fresh, dry air diffuses outward from the booster column as the center. The middle exhaust pipe is placed on the outer periphery of the booster column. It absorbs the surrounding heat through heat exchange and is discharged using the high-pressure airflow of the outer booster.

[0040] In this embodiment, hot air is discharged into the cavity between the inner support cover 3 and the outer protective cover 4. The inner support cover 3 prevents hot air from re-entering the shallow circular silo. This structure forms an insulation layer with good heat insulation effect. For exhaust, an exhaust window 11 is provided on the outside of the cavity, which is closed at the top of the central cylinder 5 and connected to the inside of the silo body 1 at the bottom. An axial flow fan 13 for injecting air into the cavity is provided on the side of the central cylinder 5. By arranging a double-layer silo top structure, the hot air discharged from the side exhaust heat pipe 7 and the inner surrounding exhaust pipe 8 is placed in this cavity, preventing it from entering the silo, and is directly discharged from the inside and outside of the cavity. At the same time, the double-layer structure has a good heat insulation effect, ensuring that the grain silo is free from interference and has a suitable temperature.

[0041] This implementation example Figure 2 As shown in the figure, multiple inner-circling exhaust pipes 8 are arranged around the outer periphery of the air-increasing pipe 9. This embodiment shows four, but of course, three, six, eight, etc. can also be arranged. The concept is to arrange the inner-circling exhaust pipes 8 around the outer periphery of the air-increasing pipe 9, with one intake and multiple exhausts, which can effectively dissipate heat. The upper part of the inner-circling exhaust pipe 8 and the side exhaust heat pipe is provided with a cover 10. The cover 10 can prevent impurities from entering the side exhaust heat pipe 7 and the inner-circling exhaust pipe 8.

[0042] The shallow circular silo is equipped with side exhaust components and internal breathing components. The side exhaust components mainly utilize a rigid side exhaust heat pipe structure arranged along the edge. The side exhaust heat pipes are directly fixed to the inner wall of the shallow circular silo, serving as the edge exhaust and heat exchange components. As for the internal breathing components, they are arranged inside the shallow circular silo. The main structure uses flexible pipes, which are suspended from the truss beams and inner support cover of the shallow circular silo and extend freely downwards. This structure hangs naturally, which can withstand the impact brought by grain filling, and is easy to install, as it only needs to hang naturally from the top.

[0043] In this embodiment, the internal breathing assembly is based on multiple inner-circular exhaust pipes and one air-increasing pipe. The inner-circular exhaust pipes are evenly distributed around the air-increasing pipe. High-pressure air is injected into the air-increasing pipe, and treated air is added into the grain silo. The inner-circular exhaust pipes absorb heat and exhaust it outward, forming a breathing assembly. The breathing assembly is evenly distributed according to the size and coverage area of ​​the grain silo to achieve air circulation inside the grain silo.

[0044] This embodiment forcibly injects pressurized air into the grain silo and exhausts it through an internally encircling exhaust pipe, continuously refreshing the air within the warehouse. This effectively solves problems such as persistent odors, cold air, humidity, and various pollution sources that arise when the warehouse is under heavy load, thus achieving air renewal. Besides purifying the warehouse air, it effectively improves the material storage environment. It can effectively improve the temperature and humidity within the warehouse, preventing material corrosion caused by dry air, thereby protecting the quality of stored materials and products.

[0045] Example 2 further illustrates the installation structure of the outer protective cover and the inner support cover.

[0046] In this embodiment, the outer protective cover 4 is connected to the central cylinder 5 by fixing rods 12. Due to the spaced arrangement of the fixing rods 12, a hollow structure is formed between the outer protective cover 4 and the central cylinder 5, exposing the upper part of the cavity. A sealing cover 14 is provided at the exposed part. The sealing cover 14 is an inclined structure. The upper part of the sealing cover 14 is sealed and fixed to the bottom of the cover of the central cylinder. The lower part of the sealing cover 14 is fixed to the upper part of the outer protective cover 4 by the support leg 15, and the exposed part is sealed. At the same time, an air intake structure is formed at the support leg 14. An exhaust port 18 is provided on the central cylinder 5. The exhaust port 18 is connected to the exposed part of the outer protective cover and is also connected to the air intake of the axial flow fan 13 after being sealed by the pipe 19.

[0047] This embodiment utilizes the axial flow fan 13 to draw in air from the outside and inside the grain silo, thus achieving ventilation to a certain extent. Figure 5 As shown in the diagram, the axial flow fan 13 is arranged below the inner support cover and the outer protective cover, and generates airflow from top to bottom to blow air onto the upper opening of the inner surrounding exhaust pipe and the side heat pipe, which can effectively exhaust the hot air between the inner support cover and the outer protective cover.

[0048] To enhance the air extraction strength from the grain silo, this embodiment features an adjusting sleeve 25 threaded onto the outer side of the enclosure 14, partially sealing the support leg structure. A handle is provided on the adjusting sleeve 25; rotating the handle allows the adjusting sleeve 25 to rotate outside the enclosure 14. The adjusting sleeve 25 is implemented as a lightweight plastic sleeve, and the threads seal off the exposed support legs. In severe weather conditions such as strong winds or heavy rain, it can close the air inlet of the enclosure. Simultaneously, this structure can appropriately close the air inlet of the enclosure when the axial flow fan is started, increasing the amount of air extracted from the grain silo by the axial flow fan and achieving internal ventilation.
