Abstract
Official abstract text for this publication.
A coolant tank includes: a tank main body configured to store a coolant discharged from a processing machine; a vortex flow generator that creates a vortex flow of the coolant in the tank main body; and a float configured to float on a liquid surface of the coolant stored in the tank main body. An outer peripheral portion of the float has a shape conforming to a shape of an inner peripheral wall surface of the tank main body and forming a gap between the outer peripheral portion and the inner peripheral wall surface.
First claim
Opening claim text (preview).
What is claimed is: 1. A coolant tank comprising: a tank main body configured to store a coolant discharged from a processing machine; a vortex flow generator that creates a vortex flow of the coolant in the tank main body; and a float configured to float on a liquid surface of the coolant stored in the tank main body and move on the liquid surface due to the vortex flow of the coolant to collide with an inner peripheral wall surface of the tank main body. 2. The coolant tank according to claim 1 , wherein an outer peripheral portion of the float has a shape conforming to a shape of the inner peripheral wall surface of the tank main body and a shape being defined such that a gap between the outer peripheral portion and the inner peripheral wall surface is formed. 3. The coolant tank according to claim 1 , wherein a shape of the inner peripheral wall surface of the tank main body and a shape of an outer peripheral portion of the float are shapes similar to each other. 4. The coolant tank according to claim 3 , wherein each of the shape of the inner peripheral wall surface of the tank main body and the shape of the outer peripheral portion of the float is a circular shape. 5. The coolant tank according to claim 3 , wherein each of the shape of the inner peripheral wall surface of the tank main body and the shape of the outer peripheral portion of the float is a rectangular shape. 6. The coolant tank according to claim 1 , wherein the tank main body stores a coolant in which sludge is mixed.
