1. A slurry storage and stirring device comprising:
a container capable of storing a slurry containing particles and a solvent;
a main pipeline whose one end is connected to the container and the other end extends to an inner space of the container and toward a bottom surface of the inner space, forming a first circulation path of the slurry;
a nozzle attached to the other end of the main pipeline;
a pump which is provided in the first circulation path between one end and the other end of the main pipeline and sucks and pressurizes the slurry;
a sub-pipeline which branches from the pump or branches from the main pipeline between the pump and the nozzle and extends to the inner space of the container, forming a second circulation path of the slurry;
a valve which switches distribution of the slurry to one or both of the first circulation path and the second circulation path; and
a discharge port provided at a tip opposite to a branch end of the sub-pipeline and located below the nozzle in a vertical direction.
