Method of on site oil recycling

Used oil passes through a centrifuge tank for particulate separation. The oil then passes through an inlet control valve into an oil passageway. The oil passageway transfers the oil, by way of an oil pump, to a second tank and then through a five micron oil filter, through a one micron oil filter, through a two hundred and twenty nanometer oil filter, and through a one micron filter, under six BARS of pressure. There is an outlet valve which received filtered oil from the one hundred nanometer filter.

FIELD OF THE INVENTION

The present invention relates to a Method of On Site Oil Recycling and more particularly pertains to a method for recycling oil.

DESCRIPTION OF THE PRIOR ART

The use of oil recycling is known in the prior art. More specifically, oil recycling previously devised and utilized for the purpose of converting used oil into reusable oil are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the number of designs encompassed by the prior art which has been developed for the fulfillment of countless objectives and requirements.

While the prior art devices fulfill their respective, particular objectives and requirements, the prior art does not describe Method of On Site Oil Recycling that teaches an oil recycling device, which can be used at individual locations, such as auto repair centers.

In this respect, the Method of On Site Oil Recycling, according to the present invention, substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of providing a method for recycling oil.

Therefore, it can be appreciated that there exists a continuing need for a new and improved Method of On Site Oil Recycling which can be used as a method for recycling oil. In this regard, the present invention substantially fulfills this need.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of oil recycling now present in the prior art, the present invention provides an improved Method of On Site Oil Recycling. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved Method of On Site Oil Recycling and method which has all the advantages of the prior art and none of the disadvantages.

In describing this invention, the word “coupled” is used. By “coupled” is meant that the article or structure referred to is joined, either directly, or indirectly, to another article or structure. By “indirectly joined” is meant that there may be an intervening article or structure imposed between the two articles which are “coupled”. “Directly joined” means that the two articles or structures are in contact with one another or are essentially continuous with one another.

In describing aspects of the invention, the word “generally” may be used. The term, “generally” when used to describe a configuration means that the configuration includes those aspects which are within normal manufacturing parameters of acceptance. By way of example, the term “generally round” may be used. This should be interpreted to mean that the configuration may be perfectly round, but may also have a radius which is not exact, but is within the manufacturing parameters. For example, a basketball may be generally round, but not be perfectly round.

By adjacent to a structure is meant that the location is near the identified structure.

To attain the herein stated goals, the present invention essentially comprises a method for on-site oil recycling comprising several steps.

First provided is a volume of used oil. The oil is then placed in a centrifuge tank wherein the oil is spun to remove large particles and sediment from the oil. The centrifuge tank is coupled to an oil passageway. The oil passageway is a conduit or pipe, sufficient to transfer oil from one location to another.

The method uses a system inlet control valve within the oil passageway for controlling the flow of oil through the filtering system.

The method uses an oil transfer pump having an oil passageway inlet and an oil passageway outlet. The oil transfer pump receives the volume of oil through the oil passageway. The oil transfer pump oil passageway outlet has a pressure gauge to monitor pressure within the oil passageway. The oil is transferred from the oil transfer pump to a second tank through the oil passageway.

The second tank has an oil passageway inlet and an oil passageway outlet. The second tank has a pressure relief valve for allowing overpressurized oil to be transferred back to the oil passageway inlet of the oil transfer pump.

A five micron oil filter has an oil passageway inlet and an oil passageway outlet. The oil passageway outlet of the second tank provides the volume of oil to the five micron oil filter oil passageway inlet. The volume of oil passes, under pressure, through the five micron oil filter from the oil passageway inlet. The volume of oil passes through the five micron filter and out of the five micron filter through the oil passageway outlet of the five micron filter.

A one micron oil filter has an oil passageway inlet and an oil passageway outlet. The oil passageway outlet of the five micron filter provides the volume of oil to the oil passageway inlet of the one micron oil filter. The volume of oil passes, under pressure, through the one micron oil filter from the oil passageway inlet, through the one micron filter and out of the one micron filter through the oil passageway outlet of the one micron filter.

A two hundred and twenty nanometer oil filter has an oil passageway inlet and an oil passageway outlet. The oil passageway outlet of the one micron filter provides the volume of oil to the two hundred and twenty nanometer oil filter oil passageway inlet. The volume of oil passes, under pressure, through the two hundred and twenty nanometer oil filter from the oil passageway inlet, through the two hundred and twenty nanometer oil filter, and out of the two hundred and twenty nanometer oil filter through the oil passageway outlet of the two hundred and twenty nanometer oil filter.

A one hundred nanometer oil filter has an oil passageway inlet and an oil passageway outlet. The oil passageway outlet of the two hundred and twenty nanometer filter provides the volume of oil to the one hundred nanometer oil filter oil passageway inlet. The volume of oil passes through the one hundred nanometer oil filter from the oil passageway inlet, through the one hundred nanometer oil filter and out of the one hundred nanometer oil filter through the oil passageway outlet of the one hundred nanometer oil filter.

Lastly, the oil passageway has an outlet valve which is coupled to the outlet oil passageway of the one hundred nanometer filter.

It is therefore an object of the present invention to provide a new and improved Method of On Site Oil Recycling which has all of the advantages of the prior art oil recycling and none of the disadvantages.

It is another object of the present invention to provide a new and improved Method of On Site Oil Recycling which may be easily and efficiently manufactured and marketed.

It is further object of the present invention to provide a new and improved Method of On Site Oil Recycling which is of durable and reliable constructions.

An even further object of the present invention is to provide a new and improved Method of On Site Oil Recycling which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such Method of On Site Oil Recycling economically available to the buying public.

Even still another object of the present invention is to provide a Method of On Site Oil Recycling for use in individual locations, such as auto service centers.

Lastly, it is an object of the present invention to provide a new and improved oil recycling method, wherein used oil passes through a centrifuge tank for particulate separation. The oil then passes through an inlet control valve into an oil passageway. The oil passageway transfers the oil, by way of an oil pump, to a second tank and then through a five micron oil filter, through a one micron oil filter, through a two hundred and twenty nanometer oil filter, and through a one micron filter, under six BARS of pressure. There is an outlet valve which received filtered oil from the one hundred nanometer filter.

It should be understood that while the above-stated objects are goals which are sought to be achieved, such objects should not be construed as limiting or diminishing the scope of the claims herein made.
