Technical Field
[0001] This utility model relates to the technical field of steel silos, and in particular to a prefabricated steel silo. Background Technology
[0002] In industries such as agriculture, building materials, and chemicals, traditional warehousing facilities (such as concrete silos and brick-concrete warehouses) have the following problems in meeting the storage needs of bulk materials:
[0003] 1. Long construction period: It requires on-site pouring or masonry, and is greatly affected by weather and construction conditions. The construction period usually takes several months.
[0004] 2. High cost: Material, labor and transportation costs account for a large proportion, and the products are difficult to reuse;
[0005] 3. Poor flexibility: Fixed structures make it difficult to adjust scale or relocate according to changes in production capacity;
[0006] 4. Complex maintenance: Concrete is prone to cracking and brick-concrete structures are susceptible to moisture, requiring regular repairs; therefore, steel silos that are easy to load and unload are needed.
[0007] Currently, in existing steel silos, such as the patent with announcement number CN218087028U, this utility model relates to a prefabricated steel silo, including a silo body, a discharge pipe at the lower end of the silo body, and a feed pipe on the top side wall of the silo body. The characteristic is that: the discharge pipe is provided with an anti-accumulation mechanism, and the top of the silo body is provided with a rainproof mechanism, the rainproof mechanism including a ventilation cover and a rainproof cover, and the top of the silo body is connected to the ventilation cover.
[0008] However, it has been found in the use of existing steel silos that they are not convenient for switching freely between ventilation and sealing. When the external environment is relatively humid, continuous ventilation can easily cause internal dampness, affecting the storage quality of goods. Utility Model Content
[0009] To solve the above-mentioned technical problems, this utility model provides a prefabricated steel silo that reduces material deposition and moisture absorption. When the external environment is humid, multiple sets of ventilation openings are closed by controlling the sealing mechanism, thereby reducing the moisture absorption of materials during storage and improving the convenience of opening and closing the ventilation openings.

At the same time, the stirring device is turned on periodically to circulate the material in the cylinder and hopper, thereby reducing the sedimentation and moisture absorption of the material. When the external environment is humid, the multiple sets of ventilation openings are closed by controlling the sealing mechanism to reduce the moisture absorption of the material during storage and improve the storage quality of the material.

[0013] Preferably, the support mechanism includes a bracket and a limiting ring. The bracket is fitted onto the outside of the cylinder, and the limiting ring is disposed on the outer side wall of the cylinder. The winding wheel and the worm gear are rotatably mounted on the bracket. The cylinder is inserted downward into the bracket, and the limiting ring supports the cylinder, thereby allowing the cylinder to be mounted on the bracket.

[0017] Preferably, it also includes anti-slip feet, which are installed at the bottom of the bracket to improve the stability of the bracket during use.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: the cylinder and the hopper are assembled into an integral steel silo, and then the material is stored in the steel silo through the top of the hopper. Then the cover is installed on the top of the hopper. During the material storage process, the material is ventilated to the outside through multiple sets of ventilation openings. At the same time, the stirring device is turned on periodically to make the stirring device circulate the material in the cylinder and the hopper, thereby reducing the sedimentation and moisture absorption of the material.
