Abstract
A peristaltic pump system has a pump tube and a pump rotor engaging the pump tube. The pump rotor is drivable to rotate to move a pump fluid through the pump tube from a pump inlet to a pump outlet. A motor drives the pump rotor to rotate. The motor includes a motor tube and a motor rotor to be driven to rotate by a motor fluid moving through the motor tube from a motor inlet to a motor outlet. A urine treatment system and method are also disclosed.
Claims20
A peristaltic pump system comprising:
- a pump tube and a pump rotor engaging said pump tube, said pump rotor being drivable to rotate to move a pump fluid through said pump tube from a pump inlet to a pump outlet;
- and
- a motor for driving said pump rotor to rotate, said motor including a motor tube and a motor rotor to be driven to rotate by a motor fluid moving through said motor tube from a motor inlet to a motor outlet.
A urine treatment system comprising:
- a container to receive urine from a toilet, and a pump for delivering an acid into said container and a motor for delivering water into said container;
- said pump including a pump tube and a pump rotor engaging said pump tube, said pump rotor being drivable to rotate to move the acid through said pump tube from a pump inlet to a pump outlet;
- and
- said motor for driving said pump rotor to rotate, said motor including a motor tube and a motor rotor to be driven to rotate by pressurized water moving through said motor tube from a motor inlet to a motor outlet.
1 more element
The method of treating urine comprising the steps of:
- a) delivering urine from a toilet into a container;
- b) driving a pressurized fluid into a motor tube, said motor tube forming pinch points with a motor rotor, and said pressurized fluid moving said pinch point to drive said motor rotor to rotate;
- c) driving a pump rotor by rotation of said motor rotor, said pump rotor forming pinch points on a pump tube, and delivering a pump fluid into said pump tube, with rotation of said pump rotor causing said pinch points to move, and in turn move said pump fluid from a pump inlet to a pump outlet, and moving said pump fluid from said pump outlet into said container, and delivering said motor fluid from a motor outlet into said container.
