What Is a Silo?

Warehouse for bulk materials. It is divided into agricultural silos and industrial silos. Agricultural silos are used to store grain and powder materials such as grain and feed; industrial silos are used to store coke, cement, salt, sugar and other bulk materials. The cost of mechanized silos is generally about 1/3 higher than the cost of mechanized room silos, but it can shorten the loading and unloading process of materials, reduce operating and maintenance costs, eliminate heavy bagging operations, and is conducive to mechanized and automated operations. One of the main forms of granaries.

The flat shapes of the silo include square, rectangle, polygon and circle. The silo wall of a circular silo is reasonably stressed, so special attention should be paid to ground survey and foundation design. The materials are economical, so it is the most widely used. When the stored materials are of a single type or a small amount, they should be arranged in independent warehouses or single rows. When there are many kinds of stored materials or large reserves, they are arranged in group warehouses. The space between the silos is called a star silo and is also available.

The total length of cylindrical group silos generally does not exceed 60 meters, and the total length of square group silos generally does not exceed 40 meters. When the length of the group warehouse is too large or the force and the foundation situation are more complicated, appropriate measures should be taken.

Silos are made of masonry, wood,

The friction between the material and the warehouse wall will reduce the pressure of the material on the warehouse wall and the warehouse bottom. In the calculation, according to different stress conditions, it can be divided into deep warehouse and shallow warehouse, when H / D 1.5 (H is the warehouse depth, D is the inner diameter of the round warehouse or the short side length of the rectangular warehouse or the inscribed circle diameter of the regular polygon warehouse ) Weigh deep positions, shallow positions when less than 1.5. Deep positions should take into account the above frictional effects, shallow positions can be ignored.

The bottom structure of the warehouse not only bears the weight of the material, but also needs to have a discharge function, so it is usually in the shape of a funnel. Although the bottom of the flat silo is simple in structure, it needs to fill the slope, which consumes material and increases weight. It is only suitable for small silos. In the earthquake zone, the support structure of the silo should preferably adopt the structural form of the cylindrical wall support, but for natural ventilation and daylighting, the structural form of the column net support can also be used.

Silos have the characteristics of fast loading, large and uneven loads, so special attention should be paid to foundation survey and foundation design, and the loading rate and loading uniformity should be controlled in the early stage of use to avoid accidents. Canada
