Large steel silo-related performance, structural description

One, a library mode and flow: gas discharge, when the station up to 500 tons.

The traditional structure of unloading silo approach commonly used material from the outflow, but as long cement storage, if there is no external force alone, since the outflow of materials, the library rate is quite low, generally not more than 70%. Due to the large steel library of special gasification gas flow pneumatic pipe discharging device combining to make the library cement first produced fluidized state, the bottom discharge chute angle greater than the angle of the natural flow of the material, the material trough discharge flows, and then passes through the center of the chamber were homogenized, and transmission by the transmitter

Chung tube sent outside the library, so even very large area of ​​the reservoir bottom, but also to ensure emptying rate of over 90%. By lifting equipment or pneumatic conveying equipment will be sent packing warehouse or bulk cement cement irrigation, according to customer requirements for the design flow library, a library of single pipeline capacity up to 500t / h, more traffic can be double-pipe and multi-channel portfolio to meet customer requirements.

Second, the storage of materials: mechanical, pneumatic can

Material storage methods can be used depending on the circumstances of each plant hoist warehousing, storage or chute pneumatic conveying pipeline storage and other means. Between the library roof, the library can be set up between the top of the bridge and hoist frame in order to install the storage material handling equipment.

Third, small energy consumption: 0.3 kWh per tonne of cement.

Because the large silo with a gas flow of gas homogenization, gas transportation library integrated design concepts, namely the principle of multi-purpose stretch, you can save a lot of gas source. In consideration of longer term storage of cement, bulk density increases, the discharge pressure of the air to make use of the gas source, the central area and the low-pressure gas supply fan Luo delivery times Chung tube uses. Tons of cement gas homogenization, unloading, transport integrated power consumption is about 0.3 degrees, such as cement storage time is too long, the power consumption will be relatively increased.

Fourth, structural shapes and sizes

The effective diameter of the large silo up to ten meters to tens of meters higher than the average diameter of 1: 1 or so. Library body is cylindrical, hemispherical-shaped top of your library for a circular warehouse. Library wall using welded steel; ball missing its top semicircle body shape library is a unique architectural structure through a combination of special design and multiple arched beams formed, it is reasonable to make the dome of the building structure with reliable carrying capacity. Reservoir bottom shape is concave, using a wedge force booster design principle, under different climatic conditions and geological structure, its design parameters are different.

Fifth, the storage capacity of the material and the material density: Single storage capacity 100,000 tons.

Cement single storage capacity can be built 1-10 million tons, while total reserves formed into dozens of tons of cement silo base. Cement and cement density related reserves, through the chute containing large gas storage density cement smaller, usually around 1.2, placing some time to reach 1.4-1.5, such as placing a longer time to reach about 1.7. Under normal circumstances cement storage density by 1.45 to calculate.
