ELECTRICALLY-CONDUCTIVE LIQUID PUMP
Document Type and Number:
Japanese Patent JP2020065318
Kind Code:
A
Abstract:
To provide an electrically-conductive liquid pump that can pump up an electrically-conductive liquid rising along a flow path by adding a driving power regardless of the height of the flow path.SOLUTION: An electrically-conductive liquid pump for pumping up an electrically-conductive liquid comprises a non-contact type stirrer and a case for housing the stirrer. The stirrer roughly having a cylindrical shape can be rotatably driven around the central axis in the vertical direction and includes a plurality of magnet bodies extending vertically on the side surface. The magnet bodies are placed side by side in the circumferential direction so that their magnetic poles on the outer peripheral surface are alternately different. The case has a tubular side wall part extending vertically. The side wall part includes: a spiral flow path around the vertical axis which is formed inside the wall; and an inlet and an outlet which open toward the outside of the side wall part at the lower and upper ends of the flow path.SELECTED DRAWING: Figure 1
