Description

Technical Field

[0001] This utility model belongs to the technical field of grain storage equipment, specifically relating to a grain safe storage device. Background Technology

[0002] Safe grain storage is a crucial link in ensuring national food security and reducing post-harvest losses. Grains continuously respire during storage, releasing moisture and heat. If the humidity in the storage environment is too high (usually exceeding 65% relative humidity), it can easily cause grain to clump, heat up, or even become moldy. At the same time, it provides suitable breeding conditions for storage pests (such as corn weevils and rice weevils), further accelerating the deterioration of grain quality. Therefore, moisture prevention and humidity control are the core technical requirements for safe grain storage.

[0003] Traditional grain silos rely primarily on desiccant adsorption for moisture control. This involves placing desiccant packets (such as silica gel or calcium chloride) in easily accessible areas like the lid, bottom, or side walls of the silo to reduce localized humidity. However, this design has significant limitations: First, due to the nature of grain stacking, the exchange of air between the grain and the outside environment in the central area of ​​the silo is slow, leading to moisture buildup and the formation of a "wet core." Because of the grain's obstruction, traditional desiccant packets cannot be effectively placed in the center of the silo, failing to effectively dry this area and significantly increasing the risk of mold growth. Second, replacing desiccant packets is difficult and prone to damage. Traditional grain silos are mostly closed structures, requiring the removal of some grain or opening of large silo lids for replacement, a time-consuming and labor-intensive process that can easily result in spilled grain and contamination. Therefore, this invention proposes a safe grain storage device. Utility Model Content

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. Example

[0016] Please see Figures 1 to 5 This is an embodiment of the present utility model, which provides the following technical solution: a grain safe storage device, including a grain silo 1, and further comprising... The central drying base cylinder 6 is welded and fixed at the center of the inner side of the grain silo 1; the central drying package 64 is installed inside the central drying base cylinder 6; the annular groove 61 is opened on the surface of the central drying base cylinder 6; multiple air holes 63 are opened on the inner wall of the annular groove 61 and communicate with the inner side of the central drying base cylinder 6; and the annular protective metal mesh 62 is installed in the annular groove 61. The grain silo 1 has two circular disassembly ports 11 on its surface, corresponding to the positions of the central drying cylinder 6. Two arc-shaped sealing plates 5 are fixed to the surface of the grain silo 1 to block the circular disassembly ports 11. Because the circular disassembly ports 11 correspond to the positions of the central drying cylinder 6, the arc-shaped sealing plates 5 can be removed to directly access and replace the central drying package 64 inside the central drying cylinder 6. This facilitates subsequent maintenance without requiring opening the silo or unloading the grain. During daily use, the permeability of the annular protective metal mesh 62 and the air pores 63 allows the air inside the grain silo 1 to come into contact with the desiccant inside the central drying package 64, effectively drying and preventing moisture. This achieves precise placement of the drying package at the center of the grain silo and efficient humidity control, solving the problem of inconvenient placement of the drying package at the center of the traditional grain silo.

[0017] In this embodiment, preferably, the annular protective metal mesh 62 can prevent grain from passing through but can ensure normal air passage, and the central drying package 64 contains calcium chloride desiccant.

[0018] In this embodiment, preferably, the two ends of the central drying base cylinder 6 are welded and fixed to two circular disassembly ports 11 on the inner wall of the grain silo 1, which can achieve circumferential sealing of the inner end of the circular disassembly ports 11 and ensure airtightness.

[0019] In this embodiment, preferably, the arc-shaped sealing plate 5 and the outer wall of the grain silo 1 are tightened and fixed by four bolts to ensure the stable fixing of the arc-shaped sealing plate 5. A cylindrical plug 51 is fixed at the center of the inner side of the arc-shaped sealing plate 5, and the cylindrical plug 51 is inserted into the circular disassembly port 11 and abuts against the inner wall of the circular disassembly port 11 to further ensure the sealing performance of the circular disassembly port 11.

[0020] In this embodiment, preferably, the inner surface of the arc-shaped sealing plate 5 is provided with a U-shaped groove 52 relative to the outer side of the cylindrical sealing plug 51, and a U-shaped sealing pad 53 is embedded in the U-shaped groove 52. The U-shaped sealing pad 53 is made of silicone material and abuts against the outer wall of the grain bin 1 to achieve a tight seal at the edge after the arc-shaped sealing plate 5 is fixed.

[0021] In this embodiment, preferably, the surface of the cylindrical plug 51 is provided with a plurality of integrated annular sealing protrusions 511, both of which are made of silicone material and will undergo elastic deformation when squeezed. The inner wall of the circular disassembly port 11 is provided with a plurality of annular sealing grooves 111 corresponding to the annular sealing protrusions 511. The annular sealing protrusions 511 are squeezed into the annular sealing grooves 111, further forming multiple sealing measures.

[0022] In this embodiment, preferably, the top and bottom of the grain silo 1 are respectively provided with a grain inlet 2 and a grain outlet 3 for feeding grain and subsequent grain discharge. In actual use, other drying bags can be placed at the grain inlet 2 and the grain outlet 3 to cooperate with the central drying bag 64 to effectively dry multiple areas in the grain silo 1.

[0023] In this embodiment, preferably, the surface of the grain silo 1 is welded with a plurality of support legs 4, and the bottom ends of the support legs 4 are supported on the ground.
