Abstract
A coolant filtration system including: a coolant tank including a first coolant zone and an adjacent second coolant zone; and a filtration system fluidly connected to the first coolant zone and the second coolant zone, the filtration system including an inlet located in the second coolant zone, an outlet located in the first coolant zone, a filter in fluid communication with the inlet and the outlet, and a pump that in operation pumps a coolant from the inlet in the second coolant zone to the filter such that a net positive flow of coolant is generated in the coolant tank from the first coolant zone to the second coolant zone.
Claims29
A coolant filtration system comprising:
- a coolant tank comprising a first coolant zone and an adjacent second coolant zone;
- and
- a filtration system fluidly connected to the first coolant zone and the second coolant zone, the filtration system comprising
- an inlet located in the second coolant zone,
- an outlet located in the first coolant zone,
- a filter in fluid communication with the inlet and the outlet, and
- a pump that in operation pumps a coolant from the inlet in the second coolant zone to the filter such that a net positive flow of coolant is generated in the coolant tank from the first coolant zone to the second coolant zone.
A machine comprising:
- a tool that in operation removes debris from a workpiece;
- and
- a coolant filtration system comprising:
- a coolant tank comprising a first coolant zone and an adjacent second coolant zone fluidly connected to the first coolant zone,
- a filtration system fluidly connected to the first coolant zone and the second coolant zone, the filtration system comprising
- an inlet located in the second coolant zone,
- an outlet located into the first coolant zone,
- a filter comprising in fluid communication with the inlet and the outlet, and
- a pump that in operation pumps coolant from the inlet in the second coolant zone to the filter such that a net positive flow of coolant is generated in the coolant tank from the first coolant zone to the second coolant zone.
A method of operating a coolant filtration system for a machine, the method comprising:
- pumping coolant through a coolant inlet disposed in a first coolant zone of a coolant tank to a machine;
- capturing debris and coolant from the machine in a second coolant zone of the coolant tank, wherein the second coolant zone is adjacent to the first coolant zone;
- pumping coolant from the second coolant zone through an inlet of a filtration system, wherein the inlet of the filtration system is located within the second coolant zone;
- filtering the coolant with the filtration system;
- and
- returning coolant from the filtration system to the first coolant zone through an outlet of the filtration system such that a net positive flow of coolant is generated in the coolant tank from the first coolant zone to the second coolant zone.
A coolant filtration system for use with a metal working machine, the coolant filtration system comprising:
- a coolant tank comprising a first coolant zone and a second coolant zone fluidly connected to the first coolant zone, wherein the second coolant zone is configured to receive debris and coolant from the metal working machine;
- a filtration system fluidly connected to the first coolant zone and the second coolant zone, the filtration system comprising
- an inlet located in the second coolant zone,
- an outlet located in the first coolant zone,
- a filter in fluid communication with the inlet and the outlet, and
- a pump that in operation pumps coolant from the inlet in the second coolant zone to the filter system such that in operation a net positive flow of coolant is generated in the coolant tank from the first coolant zone to the second coolant zone;
- a first filter disposed above the second coolant zone, wherein the first filter in operation receives coolant and debris from the machine, captures debris of a defined first size within the first filter, and allows coolant to pass through the first filter;
- a collector located within the second coolant zone and below the first filter, wherein the collector in operation receives coolant and debris from the machine, and wherein the inlet of the filtration system is located within the collector and proximate to the bottom of the collector;
- and
- a vertical filter between the first coolant zone and the second coolant zone.
