Performance characteristics:
- Silos are warehouses for storing bulk materials, which are divided into two categories: agricultural silos and industrial silos.
- Agricultural silos are mainly used to store grain, feed and other granular and powdery materials.
- Industrial silos are used to store coke, cement, salt, sugar and other bulk materials.
- Although the cost of mechanized silo is about 1/3 higher than the room type silo, it can shorten the material loading and unloading process, reduce the operation and maintenance costs, eliminate the heavy bagging operation, and is conducive to mechanization and automation, so it has become one of the most important forms of grain silo .
Main technical parameters:
- The design and construction of silo needs to ensure that the silo wall strength meets the required requirements, while the inner wall should be flat and smooth for easy material loading and unloading. The layout should be reasonable to save the area. The unloading funnel is installed at the bottom, and the upper corridor is equipped with transportation equipment for loading materials.
- When loading, the bulk material is transported to the upper corridor through the elevator and unloaded into the horizontal belt conveyor, and then unloaded into the silo inlet. When unloading, the bulk material is discharged through the discharge hopper to the lower gallery and transported out by the horizontal belt conveyor.
- Appropriate equipment and devices are required to automate the operation step by step.
- The plane shape of the silo can be square, rectangle, polygon and circle. Round silo wall force is reasonable, so in the foundation survey and foundation design should pay special attention to the material economy, so the most widely used. When the storage of a single species of materials or storage capacity is small, with an independent silo or single column arrangement. When the storage of more varieties of materials or storage capacity, it is arranged into a group of silos. The space between the silo is called star warehouse , can also be used.
- Silos are constructed of masonry, wood, reinforced concrete or steel. Small silos can also be made of plastic. Masonry material has the characteristics of convenient material, low cost and easy construction, so it is widely used. Masonry silo with a large height, the configuration of ring steel or reinforced concrete ring beams set every certain height to withstand the ring tension. Masonry silos are mostly under 6 meters in diameter and not more than 20 meters in height. Reinforced concrete silo for larger capacity, its diameter in the group silo up to 12 meters, in the independent silo up to 18 meters or more, its height according to the capacity of lifting equipment and economic efficiency, generally about 35 meters, with airflow conveying into the silo of cement silo up to 50 meters. Steel is generally only used to manufacture the funnel of the silo.
Main application areas:
- Silos are widely used in agriculture and industry for storing various bulk materials. They are particularly suitable for occasions where large quantities of storage and rapid loading and unloading of materials are required, such as grain processing, cement production, chemical raw material storage and so on.
Important Tips:
- The construction of silos should take into account accessibility, environmental factors and the possibility of connection to infrastructure. Setting up near the sea should be avoided to prevent rusting of steel plates.
- There are various plane shapes of silos, but round silos are most widely used because of reasonable force and economical material.
- The space between silos, i.e. star silos, can also be utilized.
- The length and layout of the silo should be reasonably designed according to the material varieties, storage capacity and foundation condition.
- Drying, weighing, turning, sterilizing and cleaning are also carried out before the grain enters the silo, during the storage period and after it leaves the silo.
- Silo construction materials include masonry, wood, reinforced concrete or steel, small silos can also be made of plastic. In order to ensure the safe use of the silo, corresponding management procedures should be formulated, and the silo pressure test and equipment test run should be carried out to ensure that the silo settles stably and the equipment operates normally before it is put into use.
- Personnel in the silo operation area should wear anti-static clothing to prevent static sparks. Shoes with iron nails and palms are not allowed, and bringing in fire is strictly prohibited.
- Ensure operation safety, avoid equipment damage, dust explosion and personal injury and other major accidents, and safeguard the lives of employees and the company's property.
