[0002] A sealed powder storage and transportation silo is a device used for storing and transporting bulk powdery materials. It typically has a closed structure, which can effectively prevent dust leakage and environmental pollution. This equipment is widely used in various industrial fields, such as construction sites, cement precast plants, and concrete mixing plants. It is mainly used for storing bulk powdery materials such as cement, mineral powder, and fly ash.

[0003] In industries such as food, chemical, and pharmaceutical, the storage and transportation of powders (such as flour, charcoal powder, catalysts, etc.) is a critical link. To ensure product quality and stability, powders need to be protected from contact with the external environment during storage and transportation to prevent contamination and to prevent physical or chemical changes such as oxidation and deliquescence during storage and transportation. However, in traditional powder storage methods, the stickiness and moisture content of powdered materials can cause them to adhere to the inner walls of storage silos. Prolonged adhesion can seriously affect the storage quality and efficiency of materials, and can also cause hygiene and safety problems, thereby increasing production and cleaning costs.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4This utility model provides a device for preventing material accumulation on the inner wall of a sealed powder storage and transportation silo. It includes a silo 1 and a side plate 18 on one side of the silo 1. A fixing block 20 is bolted to the inner wall of one side of the silo 1. The fixing block 20 has a groove, and a connecting shaft 16 is rotatably connected within the groove. The end of the connecting shaft 16 away from the fixing block 20 is fixed to a rotating shaft 13. After the locking structure is opened, the connecting shaft 16 can be pulled out from the groove. The groove on the fixing block 20 also assists in positioning the connecting shaft 16 during installation. A feed pipe is located at the top of the outer circumference of the silo 1, and the top of the feed pipe has a protective feature for the feed inlet. The protective cover, when the material has finished being conveyed from the feed pipe, also serves to protect the material and prevent external dust from entering the silo 1, thus improving the safety of the silo 1. A discharge pipe is located at the bottom of the outer circumference of the silo 1. One end of the discharge pipe is fixed with a valve by bolts. The discharge pipe facilitates the removal of material, and rotating the valve can adjust the discharge rate. Multiple locking mechanisms are provided on the outer circumference of the silo 1 for the side plate 18. A connecting pipe 19 is rotatably connected to the inside of the side plate 18 via bearings. A rotating shaft 13 is rotatably connected to the inner circumference of the connecting pipe 19. One end of the connecting pipe 19 and the outer circumference of the rotating shaft 13 are both... A connecting frame 15 is bolted to the side plate 18, and a scraper 14 is bolted to the top of the connecting frame 15. A drive mechanism is provided on one side of the side plate 18 to drive the connecting pipe 19 and the rotating shaft 13 to rotate in opposite directions. The drive mechanism includes a double-shaft cylinder 7 bolted to one side of the side plate 18. A slide plate 8 is bolted to the two telescopic ends of the double-shaft cylinder 7. A first rack 10 and a second rack 11 are bolted to the diagonally opposite bottom of the slide plate 8. A second gear 9, meshing with the second rack 11, is keyed to the outer circumference of the connecting pipe 19. A first gear 12, meshing with the first rack 10, is keyed to the outer circumference of the rotating shaft 13. The side plate 18 is activated. The dual-axis cylinder 7 drives the first rack 10 and the second rack 11 at the bottom of the push plate 8 to move downwards simultaneously. The first rack 10 and the second rack 11 drive the first gear 12 and the second gear 9 to rotate in opposite directions. The rotation of the first gear 12 and the second gear 9 will drive the rotation of the connecting pipe 19 and the rotating shaft 13. The connecting pipe 19 and the rotating shaft 13 will drive the scraper 14 fixed on the connecting frame 15 to rotate along the inner wall of the hopper 1. The two scrapers 14 will simultaneously perform opposite scraping actions on the inner wall of the hopper 1, which will cause the residues adhering to the inner wall of the hopper 1 to fall off, thus improving the efficiency of scraping the residues in the hopper 1.

[0024] In this embodiment, the locking mechanism includes two protrusions 6 fixed to the outer circumference of the hopper 1 by bolts. A fixing frame 3 is fixed to one side of the side plate 18 by bolts. A threaded rod 4 is rotatably connected inside the fixing frame 3. A stop block 5 is threadedly connected to the outer thread of the threaded rod 4. One side of the side plate 18 is aligned with one side of the hopper 1 so that they fit together. The threaded rod 4 is rotated between the two protrusions 6. Then, the stop block 5 is rotated continuously so that the stop block 5 fits tightly against one side of the two protrusions 6 and forms a compression state, so that the side plate 18 and the hopper 1 form a sealed state, which improves the sealing strength inside the hopper 1 and realizes the protection of the material inside the hopper 1, preventing damage to the material inside the hopper 1 caused by external impurities and moisture. At the same time, when the locking mechanism is opened, the side plate 18 and the internal components can also be disassembled and cleaned.

[0025] In this embodiment, multiple stirring racks 17 are welded to the outer circumference of the connecting shaft 16, and all stirring racks 17 are spiral-shaped. When the rotating shaft 13 rotates, it will drive the connecting shaft 16 to rotate, and the stirring racks 17 on the connecting shaft 16 will rotate, thereby stirring the material in the hopper 1, so that the material is always in a state of motion, which reduces the occurrence of material accumulation on the inner wall of the hopper 1. The spiral-shaped stirring racks 17 can ensure that the material being stirred is fully mixed and accelerated in all directions, and the stirring speed of the material will also increase as the stirring racks 17 move.

[0026] In this embodiment, the bottom of the silo 1 is fixed with a transfer frame 2 by bolts, which facilitates the transportation of the silo 1 and improves the flexibility of the use of the silo 1.

[0027] The working principle of this utility model is as follows: First, align one side of the side plate 18 with one side of the hopper 1 so that they fit together. Rotate the threaded rod 4 between the two protrusions 6. Then, continuously rotate the stop block 5 so that the stop block 5 fits tightly against one side of the two protrusions 6, so that the side plate 18 and the hopper 1 form a sealed state. Start the double-shaft cylinder 7 on one side of the side plate 18. The double-shaft cylinder 7 drives the first rack 10 and the second rack 11 at the bottom of the push plate 8 to move downwards at the same time. The first rack 10 and the second rack 11 drive the first gear 12 and the second gear 9 to rotate in opposite directions at the same time. While the first gear 12 and the second gear 9 are rotating, they will drive the rotation of the connecting pipe 19 and the rotating shaft 13. The connecting pipe 19 and the rotating shaft 13 will drive the scraper 14 fixed on the connecting frame 15 to rotate along the inner wall of the hopper 1. The two scrapers 14 will simultaneously perform opposite scraping actions on the inner wall of the hopper 1, causing the residues adhering to the inner wall of the hopper 1 to fall off.

[0028] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
