Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and in particular to a dustproof grain storage silo. Background Technology

[0002] Grain storage silos are a crucial component of agricultural and food safety systems, primarily used to preserve and protect grain from pests, mold, and other environmental factors during storage. Modern grain storage silos typically employ steel or concrete structures, featuring excellent sealing and ventilation systems to maintain suitable humidity and temperature. These silos are also equipped with advanced monitoring technologies that allow for real-time monitoring of the grain's condition, ensuring its quality and safety.

[0003] When the grain is poured into the warehouse, it falls from a height of several meters, and dust is easily stirred up. The entire operating room is instantly covered in a hazy dust. This dust floats in the air, and when inhaled, it is dry and choking. Over time, it can cause a sore throat and cough. In the long run, it can not only damage the respiratory tract, but also increase the cleaning burden as the dust settles everywhere. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dustproof grain storage bin, which solves the technical problems of grain falling into the bin from a height of several meters when it is poured in, raising dust and making the operating room instantly dusty. Inhaling the dust causes dryness and choking, which can damage the respiratory tract in the long term. The dust also accumulates everywhere, increasing the cleaning burden.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dustproof grain storage silo includes a storage silo, a support fixedly installed at the lower end of the storage silo, a fixing ring fixedly installed inside the storage silo, inserts fixedly installed at equal intervals at the upper end of the fixing ring, inner blocks fixedly installed at equal intervals on the inner wall of the fixing ring, and first fixing balls fixedly installed at the upper ends of each of the four inner blocks, a feeding tray fixedly installed at the upper end of the storage silo, a U-shaped frame fixedly installed at the upper end of the feeding tray, a fan fixedly installed inside the U-shaped frame, a first air duct detachably installed at the air inlet end of the fan, the end of the first air duct away from the fan being disposed inside the storage silo, a second air duct detachably installed at the air outlet end of the fan, a dust collection cylinder fixedly installed on the side wall of the storage silo, a fine filter screen disposed on the side wall of the dust collection cylinder, and a screening mechanism disposed inside the storage silo, the screening mechanism including a filter screen mounting frame disposed inside the storage silo, the storage silo, support, fixing ring, inserts, inner blocks, first fixing balls, feeding tray, U-shaped frame, and U-shaped frame being fixedly installed inside the storage silo. The frame, fan, air duct, dust collection cylinder, fine filter screen and screening mechanism together form the basic structure of the dustproof grain storage silo, providing stable support for subsequent dust prevention, dust absorption and grain screening.

[0007] Preferably, the filter mounting bracket has slots equidistantly spaced at its lower end, each slot being adapted to each insert. A connecting ring is fixedly installed at the upper end of the filter mounting bracket, and a connecting frame is fixedly installed at the upper end of the connecting ring. The filter mounting bracket is securely installed by the slots adapting to the inserts on the fixed ring. The connecting ring and the connecting frame provide a reliable connection for the installation of components such as the drive motor.

[0008] Preferably, a drive motor is fixedly installed inside the connecting frame, and a rotating shaft is installed on the output end of the drive motor.

[0020] This application provides a dustproof grain storage silo, which effectively solves the problem of dust being stirred up when grain is poured into the silo from a height of several meters, instantly turning the operating room gray and causing dry and choking sensations upon inhalation, which can damage the respiratory tract in the long term. The dust also accumulates everywhere, increasing the cleaning burden. This equipment can simultaneously achieve negative pressure dust prevention at the source and efficient screening without clogging. It not only prevents dust from spreading and polluting the operating environment and harming personnel health from the source, but also prevents screen blockage through rotational centrifugal force and high-frequency micro-vibration, ensuring continuous and efficient operation of the entire process of grain feeding, impurity removal, and dust prevention. It solves the dual core pain points of traditional equipment: easy dust diffusion and frequent screening shutdowns.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the technical solution in this application embodiment effectively solves the technical problem that when grain is poured into the silo from a height of several meters, dust is raised, instantly making the operating room dusty, causing dryness and choking upon inhalation, long-term damage to the respiratory tract, and dust accumulation everywhere, increasing the cleaning burden. The overall idea is as follows: A dustproof grain storage silo includes a storage silo 1, a support 2 fixedly installed at the lower end of the storage silo 1, a fixing ring 3 fixedly installed inside the storage silo 1, and inserts 4 fixedly installed at equal intervals at the upper end of the fixing ring 3. Inner blocks 5 are fixedly installed at equal intervals on the inner wall of ring 3. A first fixed ball 6 is fixedly installed at the upper end of each of the four inner blocks 5. A feeding tray 7 is fixedly installed at the upper end of storage bin 1. A U-shaped frame 8 is fixedly installed at the upper end of the feeding tray 7. A fan 9 is fixedly installed inside the U-shaped frame 8. A first air duct 10 is detachably installed at the air inlet end of the fan 9. The end of the first air duct 10 furthest from the fan 9 is located inside storage bin 1. A second air duct 11 is detachably installed at the air outlet end of the fan 9. A dust collection cylinder 1 is fixedly installed on the side wall of storage bin 1. 2. A fine filter screen 13 is installed on the side wall of the ash collection cylinder 12. A screening mechanism is installed inside the storage chamber 1. The screening mechanism includes a filter screen mounting frame 14, which is installed inside the storage chamber 1. When in use, the filter screen mounting frame 14 can be placed inside the storage chamber 1. At this time, the insert 4 will be engaged in the slot 15, and the two will be squeezed to form a fixed position. At this time, the grain can be poured into the storage chamber 1. Then, the blower 9 can be started simultaneously. Under the action of the blower 9, the dust inside the storage chamber 1 is extracted through the two first air pipes 10 and then blown into the ash collection cylinder 12 through the second air pipe 11. Then the gas will be discharged through the fine filter screen 13, and the dust will remain inside the ash collection cylinder 12. This device can form a negative pressure adsorption through the two first air pipes 10 at the first time the dust is generated, and directly lock the dust inside the storage chamber 1. This avoids the problem of dust spreading to the operating environment caused by traditional equipment that processes grain first and then removes dust. It reduces the irritation of dust to the respiratory tract of operators from the source and reduces the cleaning burden caused by dust adhering to the surface of the equipment.

[0023] The filter mounting bracket 14 has slots 15 evenly spaced at its lower end, each slot 15 being adapted to each insert 4. A connecting ring 16 is fixedly installed at the upper end of the filter mounting bracket 14, and a connecting frame 17 is fixedly installed at the upper end of the connecting ring 16. A drive motor 18 is fixedly installed inside the connecting frame 17, and a rotating shaft 19 is installed on the output end of the drive motor 18. Through the adaptation of the slots 15 and the insert 4, the filter mounting bracket 14 can be firmly fixed in the storage chamber 1. At the same time, the connecting ring 16 and the connecting frame 17 are connected in sequence, providing a reliable mounting carrier for the drive motor 18, so that the drive motor 18 can stably transmit power through the rotating shaft 19 at the output end, thus preparing the structure and power for the subsequent screening action of the coarse filter 21.

[0024] A filter screen rib 20 is fixedly installed at the lower end of the rotating shaft 19. The filter screen rib 20 is rotatably installed in the filter screen mounting bracket 14. A coarse filter screen 21 is fixedly installed on the filter screen rib 20. Second fixed balls 22 are fixedly installed at equal intervals at the lower end of the filter screen rib 20. When in use, the drive motor 18 can be started. Under the action of the drive motor 18, the rotating shaft 19 will rotate. The rotation of the rotating shaft 19 will drive the filter screen rib 20 to rotate inside the filter screen mounting bracket 14. At this time, the coarse filter screen 21 will rotate with the filter screen rib 20. When the grain is poured onto the coarse filter screen 21, the coarse filter screen 21 can screen the grain. The rotation of the filter screen rib 20 will also cause the grain to rotate. The second fixed ball 22 will rotate accordingly, and when the second fixed ball 22 rotates, it will come into contact with the first fixed ball 6 on the inner block 5. After contact, the two will squeeze each other, and the filter screen rib 20 will drive the filter screen mounting bracket 14 to slide slightly upward on the insert 4. Under the up and down shaking of the coarse filter screen 21, the grain will be screened, so that the equipment can effectively avoid the screen holes being blocked by fine grain particles or impurities: the centrifugal force generated by rotation can throw off the particles stuck on the edge of the screen hole, and the high-frequency micro-vibration generated by shaking can shake out the impurities embedded in the screen hole. Compared with the traditional fixed screen, the screen clogging rate is reduced, and there is no need to stop the machine to clean the blockage, ensuring the continuous operation of the equipment.

[0025] To address the problems existing in the prior art, this utility model provides a dustproof grain storage silo. This equipment can simultaneously achieve negative pressure dust prevention and anti-clogging high-efficiency screening at the source, which not only prevents dust from spreading and polluting the operating environment and endangering personnel health from the source, but also prevents screen blockage through rotational centrifugal force + high-frequency micro-vibration, ensuring continuous and efficient operation of the entire process of grain feeding, impurity removal and dust prevention, thus solving the dual core pain points of traditional equipment: easy dust diffusion and frequent screening shutdowns.

[0026] Working principle:

[0027] First, when using the equipment, the filter mounting bracket 14 can be placed inside the storage chamber 1. At this time, the insert 4 will be snapped into the slot 15, and the two will be pressed together to form a fixed position. Grain can then be poured into the storage chamber 1. Then, the fan 9 can be started simultaneously. The fan 9 will draw out the dust inside the storage chamber 1 through the two first air ducts 10 and blow it into the dust collection cylinder 12 through the second air duct 11. The gas will then be discharged through the fine filter 13, while the dust will remain inside the dust collection cylinder 12. This equipment can form a negative pressure adsorption through the two first air ducts 10 at the first moment of dust generation, directly locking the dust inside the storage chamber 1. This avoids the problem of dust spreading to the operating environment caused by traditional equipment that processes grain first and then removes dust. It reduces the irritation of dust to the respiratory tract of operators from the source and reduces the cleaning burden caused by dust adhering to the surface of the equipment.

[0028] The second step involves starting the drive motor 18 during use. The drive motor 18 will rotate the rotating shaft 19, which in turn will cause the filter mesh ribs 20 to rotate inside the filter mesh mounting bracket 14. At this time, the coarse filter screen 21 will rotate along with the filter mesh ribs 20. When grain is poured onto the coarse filter screen 21, it can sieve the grain. The rotation of the filter mesh ribs 20 will also cause the second fixed ball 22 to rotate. When the second fixed ball 22 rotates, it will interact with the first fixed ball on the inner block 5. When the fixed ball 6 comes into contact, the two are squeezed together. The filter rib 20 will drive the filter mounting bracket 14 to slide slightly upward on the insert 4. Under the up and down shaking of the coarse filter 21, the grain will be screened. This allows the equipment to effectively prevent the screen holes from being blocked by fine grain particles or impurities. The centrifugal force generated by the rotation can throw off the particles stuck on the edge of the screen hole, and the high-frequency micro-vibration generated by the shaking can shake out the impurities embedded in the screen hole. Compared with the traditional fixed screen, the screen clogging rate is reduced, and there is no need to stop the machine to clean the blockage, ensuring the continuous operation of the equipment.

[0029] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
