1, the steel silo design optimization

1) the material difficulties: the perfect basis for the design waterproof structure, strict requirements for ground treatment, pneumatic conveying and air pressure balance must undergo a rigorous dry, airtight silo wall must be strictly controlled. And try resorted corridor underside is above the water table. Spout happen to be designed under seal material discharge valve malfunction during difficult to achieve under the spout repair and replacement. And to design an alternate emergency discharge through the material, so that Secure Empty library, handle unexpected difficulties harden the material, such as a fault.

2) body tilt positions: Priority rigid foundations and rigid foundation, to ensure uniform feeding stacked and give priority to a single point of the material way. Multi-point discharge despite its advantages, but due to some mistake or failure of artificial feed opening, easy to cause material deflection. Although the material can be used with multi-point corresponding weighing, metering system to ensure that all points of the same quantity, and thus prevent the material partial load, but because of the cumulative statistics and other errors, and human errors, the possibility of partial load is actually very high, and its main advantage is that will not happen because of all the feed opening which led to a large number of simultaneous failure of materials stored in the warehouse, helps to reduce the workload and difficulty clearing bank, which has outstanding advantages for a single point of the material terms. Besides multi-point higher discharge rate of the material. In soft soil, ground handling costs or large case can be used to allow the settlement of the foundation, but in the higher areas of soil bearing capacity, settlement should not use a rigid foundation.

Therefore, if the settlement allowed the foundation, you must complete a single point discharge system to prevent partial load in the warehouse, and set the emergency discharge channels and systems. If no settlement rigid base, you can use multi-point, multi-corridor discharge system, also need to clear the reservoir with the channel. Regardless of the material the way, should give priority to the material gravity-based approach to reduce the use of energy and maintenance costs, and to the strength of the material flow, supplemented;

3) Position the body should be designed to keep adequate safety margin, and temperature stress and access to material fatigue checking pressure changes, to consider limiting case materials skew stability and strength requirements of warehouse body. Shall be subject to certain body positions slightly negative pressure, the maximum snow load, wind load maximum internal storage of materials skew interaction of these four load design, the only way is safe. Normally, due to the pressure balancing effect, does not appear excessive negative pressure within the compartment case, but because of the pressure balancing system failure may occur, and difficult to timely detect, even with detection and alarm devices are bound to work after long-term adverse, causing an accident. Therefore, it should be according to the most adverse load combinations for design.
