What are the requirements for coal unloading equipment? What is the main role of the dry coal shed?

The development of dry coal shed structure has a history of twenty years so far, and the main structural forms used are plane rigid frame, plane truss, plane arch and column mesh shell structure. According to the comparison of the technical and economic indexes of the constructed dry coal shed structure, the column surface mesh shell has obvious advantages, and it has become the main structural form of the dry coal shed structure at present.

The use of mesh frame structure, so that the roof bearing capacity is reduced, generally speaking, each square meter of projected area with steel 40-70 kilograms.

With the development of China's electric power industry, dry coal shed has been widely constructed and studied. Due to the environmental protection requirements and strict control of construction land, the loose pile of coal must be replaced by closed storage, so the construction of dry coal shed in recent years in China flourished.

Structure

Generally speaking, the main function of the structure of dry coal shed is to put a cover on the coal yard in order to prevent the coal from being drenched when it rains and polluting the environment when it is windy, which is an energy-saving and environmental protection project. The building function of the dry coal shed is mainly a large storage depot. So it must have a certain storage and operation space, that is, the structure must be able to meet certain headroom requirements, and its effective use of space is trapezoidal in cross-section shape, and the envelope of the operation space is close to the arc.

Dry coal shed

The length and width of the dry coal shed structure are determined according to the needs of the installed capacity, while the height of the structure is determined by the stacking of coal and bucket wheel operation requirements. Therefore, the dry coal shed structure is characterized by a large span, high height and wide coverage area.
