Technical Field

The invention relates to equipment for measuring the water content of easily fluidized solid bulk goods, and belongs to the technical field of ship transportation.

Background

In recent years, ships carrying easily fluidized solid bulk cargo often have sinking accidents in the presence of large waves. According to relevant investigation and analysis, accidents are basically caused by that the moisture content of cargos exceeds the standard, after a carrying ship encounters large transverse wind waves in navigation, the ship swings for a long time, moisture of cargos in a cabin seeps out, liquid fluid appears on the surface, and the cargo flows to one side, so that the ship is seriously inclined and cannot recover the original state and sink. The occurrence of ship accidents for carrying easily fluidized solid bulk goods causes serious losses to the lives and properties of the nation and people, and also brings heavy pressure to the work of supervising the communication transportation safety of water supply.

The reason for the easy fluidization of ships is mainly due to the fact that the bulk cargo contains a part of fine particles and a certain amount of moisture. During transport, if the moisture content of the cargo exceeds the transportable moisture limit, the moisture will seep out into a slurry under the action of the jolts and sways of the ship, thereby having a liquid-like popularity, creating a "free surface effect" that is very dangerous for sailing. It is therefore desirable to measure the moisture content of the fluidizable solid bulk cargo to ensure that the fluidizable solid bulk cargo does not exceed the transportable moisture limit. The water content of the easily fluidized solid bulk cargo is usually manually measured in the prior art, the measurement precision is not high, and the scientificity and reliability of data are influenced.
