Description

A kind of system and method for taking grain out of a granary to sun it
Technical field
The present invention relates to management, and relate in particular to the system and method for taking grain out of a granary to sun it of the large-scale coal storage silo in a kind of harbour the large-scale coal storage silo in harbour.
Background technology
The harbour is the aortic hinge of communications and transportation, and in order to realize securely and effectively shipping functions of pivoting at the harbour, storage, transportation and technics of shipment specialized, automation all are absolutely necessary.According to the characteristic of material, the scale of shipping and the requirement of the aspects such as efficient that the material storage is transported, adopted various materials memory scheduling scheme to come shipping is coordinated in the current port traffic.Such as, adopt the mode of silo storage for materials such as grain, cement more, and to modes that adopt the open storages storage such as coal ores more.
For fortune coal harbour mouth; Open storage storage meeting causes the material of very big pollution and stacking to receive the influence of weather easily to environment; And adopting general sealing stockyard or storehouse storage, the coal ton-kilometerage volume can receive very big restriction, and the efficient of whole storage and transportation is not high.Based on above reason, adopting cylindrical silo to carry out large-scale coal storage at the harbour will be more satisfactory selection.
The silo coal storage adopts in power plant and colliery to some extent; But the colliery is short with power plant's coal storage time, storage content is little, technological process is single, less demanding to efficient, categories of coal is single and do not relate to being mixed of different coals; And the high efficiency exactly that the harbour coal storage is paid close attention to most, many kinds, the coal that is mixed, high-throughput and the long time of storing up; Therefore; If will realize the scheme of the extensive coal storage of silo at the harbour, must on structure, function and method of application, carry out suitable transformation and improvement to existing coal storage silo.
Especially, the coal that is stored in the silo can produce dieseling because of long storage time.In order to prevent the generation of this phenomenon, taked multiple measure at present: (1) adopts the principle of first in first out that the coal in the silo is managed, and shortens the time that coal stores as far as possible; And (2) regularly clear up silo, handles and stick the coal on the silo wall, stores up the generation spontaneous combustion for a long time to prevent coal.
Though said method can avoid occurring the spontaneous combustionof coal phenomenon to a certain extent, yet can't handle the situation that is about to take place spontaneous combustion or spontaneous combustion; And take place under the situation of spontaneous combustion or spontaneous combustion being about to,, the silo sidewall is opened with the mode that coal is poured out be difficult to realize because the silo diameter is bigger.
Summary of the invention
The purpose of this invention is to provide a kind of system and method, this system and method can solve existing problem under the situation that spontaneous combustion or spontaneous combustion promptly take place coal in the silo, avoids or reduces the loss that causes because of spontaneous combustionof coal.
To achieve these goals, the present invention provides a kind of system that takes grain out of a granary to sun it, and this system of taking grain out of a granary to sun it comprises: device for transporting objects, this device for transporting objects are used for that the material in the said silo is transported to one and are positioned at the exterior district that takes grain out of a granary to sun it of this silo; And control setup, this control setup is electrically connected with said device for transporting objects, is used under the situation that has the possibility that spontaneous combustion takes place, controlling said device for transporting objects the material in the silo being transported to the said district that takes grain out of a granary to sun it.
