Liquid-level following type suction apparatus and floating oil collecting system having the same

摘要

A floating oil collecting system which can collect floating oil containing a very small amount of water is provided. The system includes a liquid-level following type suction apparatus having an intake pipe in which one end is an inlet side end opening upwardly and the other end is connected with an inlet port of a pump, a float which causes the inlet side end to closely follow a liquid level within liquid in a storage tank, and an adjustment pipe which is loosely fitted to the inlet side end of the intake pipe so as to be movable up and down movement, in which an upper end opening edge is an inlet opening; a separation tank which receives an oil/water mixture from the storage tank to separate the mixture into oil and water; a pump for sucking up the oil/water mixture from the storage tank so as to be supplied to the separation tank; and a deaerator for removing air in the oil/water mixture sucked up from the storage tank.

主权项

1. A liquid-level following type suction apparatus comprising an intake pipe in which one end is an inlet side end opening upwardly and the other end is connected with a suction hose which communicates with an inlet port of a pump, a holding member fixed to said intake pipe and having an extension portion which extends outwardly, a float body attached to said extension portion of said holding member and causing said inlet side end of said intake pipe to closely follow a liquid level within the liquid, and an adjustment pipe which is loosely fitted to said inlet side end of said intake pipe through a clearance so as to move up and down, its upper opening edge serving as an inlet opening, wherein
said liquid flows from the lower end of said adjustment pipe into said clearance between the adjustment pipe and the intake pipe, said liquid rises within the clearance and is sucked into the intake pipe, and said liquid is sucked from an upper end side of said adjustment pipe into the intake pipe.
