Adjustable skimmer with pivot arms

A skimming apparatus for skimming a liquid mixture of at least two liquid components from a tank containing the mixture, comprising:

• mounting means for mounting said skimming apparatus inside said tank,
• a pump secured to said mounting means,
• means for activating said pump,
• pivot arms pivotally secured to said mounting means, said pivot arms extending between said mounting means and a skimmer, said skimmer being adapted to float on an upper surface of said liquid mixture and having an supply container defined by a bottom of said skimmer, front, rear and side walls of said skimmer, one of said side walls having a hole therethrough,
• a tube assembly extending between said pump and said supply container whereby upon activation of said pump said liquid mixture flows through an inlet in said front wall of said skimmer into said supply container, through said hole in said side wall of said supply container into said tube assembly, through said tube assembly into said pump whereby said pump pumps said liquid mixture through an outlet tube to a location outside said tank.

A skimming apparatus for skimming a liquid mixture of at least two liquid components from a tank containing the mixture, comprising:

• a mounting assembly adapted to be secured to a tank wall,
• a pump secured to said mounting assembly,
• means for activating said pump,
• an outlet adapted to convey said liquid mixture from said pump to a location outside said tank,
• a pair of pivot arms pivotally secured to said mounting assembly, said pivot arms extending between said mounting assembly and a skimmer adapted to float on said liquid mixture inside said tank,
• whereby upon activation of said pump said liquid mixture flows into a cavity of said skimmer, through a tube assembly extending between said pump and said skimmer into said pump whereby said pump pumps said liquid mixture to a location outside said tank through an outlet tube.

A skimming apparatus for skimming a liquid mixture of at least two liquid components from a tank containing the mixture, comprising:

• a mounting assembly for mounting said skimming apparatus inside said tank,
• a pump secured to said mounting assembly,
• means for activating said pump,
• pivot arms extending between said mounting assembly and a skimmer, said skimmer being adapted to float on a top surface of said liquid mixture, said skimmer having an supply container located between a pair of floats, said supply container being generally below said top surface of said liquid mixture,
• a tube assembly extending between said pump and said supply container whereby upon activation of said pump said liquid mixture is pulled into said supply container through an inlet, from said supply container into said tube assembly, through said tube assembly into said pump whereby said pump pumps said liquid mixture through an outlet to a location outside said tank, whereby said quantity of said liquid mixture entering said supply container is regulated by an adjuster in said supply container.

A skimming apparatus for skimming a liquid mixture of at least two liquid components from a tank containing the mixture, comprising:

• a bracket located in the tank at a desired vertical level;
• a floatable skimmer operatively coupled to the bracket so as to move vertically relative to the bracket depending on the level of the liquid mixture in the tank, the skimmer including a supply container having an inlet which is located below the level of the liquid mixture in the tank when the skimmer is floating and during a skimming operation, thereby to gravitationally convey liquid into the supply container, the supply container also having an outlet adjacent a bottom thereof;
• an outlet tube with a first end operatively secured to the outlet of the supply container and a second end held by the bracket, the outlet tube adapted to convey liquid outwardly from the bottom of the supply container, the outlet tube also adapted to accommodate different vertical positions of the skimmer relative to the bracket;
• and
• an adjuster located in the supply container and cooperatively interacting with the inlet to vary the size of the inlet depending on the depth of liquid in the supply container, thereby to maintain a liquid level in the supply container above the outlet.

A skimming apparatus for skimming a liquid mixture of at least two liquid components from a tank containing the mixture, comprising:

• a bracket located in the tank at a desired vertical level;
• a vacuum source operatively connected to the bracket;
• a floatable skimmer residing in the tank and floatable on the surface of the liquid mixture, for skimming liquid from adjacent the surface of the liquid mixture at varying liquid levels in the tank;
• a tube having a first end operatively connected to the skimmer and a second end secured to the bracket so as to be fluid communication with the vacuum source, the tube adapted to convey skimmed liquid from the skimmer to the vacuum source while accommodating different vertical positions of the skimmer relative to the bracket, due to varying levels of liquid in the tank;
• and
• at least one connector arm having a first end pivotally connected to the bracket and a second arm pivotally connected to the skimmer, to maintain a desired distance between the bracket and the skimmer at different liquid levels in the tank as skimming occurs.

A skimming apparatus for skimming a liquid mixture of at least two liquid components from a tank containing the mixture, comprising:

• a float,
• a mounting assembly for mounting said skimming apparatus to said float,
• arms pivotally secured to said mounting assembly, said arms extending between said mounting means and a skimmer, said skimmer being adapted to remove a quantity of said liquid mixture from said tank,
• a pump adapted to transport said quantity of said liquid mixture to a location outside said tank.
