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.
Claims3
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;
- 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;
- wherein said pump rotor and said motor rotor are in contact with said pump tube and said motor tube, respectively, and there are pinch points on said motor tube caused by said motor rotor, and the pressurized water delivered into said motor tube moves said pinch points on said motor tube to cause said motor rotor to rotate and rotate said pump rotor, and said pump rotor forming pinch points on said pump tube, and said pinch points moving as said pump rotor rotates to move the acid to the pump outlet;
- and
- a shaft connecting said pump rotor to said motor rotor, such that said pump rotor and said motor rotor are axially spaced along an axis of rotation of said shaft, and said pump rotor being fixed to one end of said shaft and said motor rotor being fixed to an opposed end of said shaft.
