Description

Harbour dry bulk cargo storage yard conveying system that gathers materials

Technical Field

The utility model belongs to the field of dry bulk material transportation, and particularly relates to an aggregate transportation system for a port dry bulk storage yard.

Background

The materials such as coal, metal mineral powder, mineral building materials and the like stacked in the port dry bulk storage yard are basically stacked in the open air, and because the port and the wharf are usually flat in ground and large in wind power, more dust is easily caused. According to statistics, the dry bulk transported by a waterway at present mainly comprises coal, ores (including metal ores and non-metal ores) and bulk grains, wherein the bulk grain loading and unloading process is mainly closed loading and unloading and silo storage, full-closed operation is carried out, and the dust yield is relatively small; the coal and ore operation process mainly comprises the links of loading and unloading ships, conveying, material stacking and taking or bagging process and the like, an open-type open-air operation mode is basically adopted, dust release forms a main body of port dust pollution, the range of port dust pollution is large, the time is prolonged, and the difficulty is brought to pollution prevention and control work. Under the combined action of dynamic loading and unloading of a stacker-reclaimer and static dust raising of stacking, an open storage yard continuously releases a large amount of dust, which not only directly causes hundreds of millions of raw material losses, but also causes serious environmental air quality pollution to the area.
