Abstract
PURPOSE: The captioned apparatus of high purification effect for floating filth on water surface and removing the same by providing a filter floating near the liquid surface to the end of the suction portion of a volume pump having an opening for sucking the atmospheric air and dischaging the air-liquid mixture to an underwater level from a discharge port of volume pump through a nozzle.
CONSTITUTION: When a switch is turned ON, a volume pump 14 operates irrespective of the opening and closing of a pressure switch 21. The air sucked through an opening 18 becomes air-liquid mixture which is then sent through nozzle 12 into hot weter. Then, the internal pressure of a discharge port 16 is increased by the back pressure of the nozzle 12 and the diaphragm 19 of a switch 21 closes a switch 20 and therefore, the pump 14 keeps running even if the switch is turned OFF. When a filter 10 becomes clogged with filth, the back pressure of the suction port 15 increases to increase the rate of air suction through the opening 18, resulting in the decreased pressure of the discharge pipe 16. Hence, the switch 21 opens to stop current supply to a drive motor 22, thereby automatically stopping the pump 14.
