INVENTOR KOTARO KONAGAI 1 BURNER MECHANISM or usnn on.
BACKGROUND OF THE INVENTION Oils used for cleaning of machine parts or for smooth operation of machines usually contain considerable amount of impurities or dusts and are generally polluted very much. Therefore, in order to make use of such used oils again, it is necessary to remove such impurities or dust positively by suitable cleaning operation. It is true that various cleaning methods have been developed for this purpose but none of the conventionally developed method could fairly succeed in an effective and economical cleaning of the used oil. This is mainly caused by the wide variety of types and kinds of the impurities and dusts contained in the used oils and wide variety of types and kinds of the used oils to be cleaned.
SUMMARY OF THE INVENTION The present invention relates to an improved burner mechanism of used oil, more particularly relates to a mechanism for burning used oil after suitable refreshment of the supplied oil which has been used for cleaning of the tools or work machines or smooth prosecution of such operations as cutting of the works.
The principal object of the present invention is to provide an improved mechanism for effectively and economically cleaning and burning used oils regardless of the types and kinds of the oils and the impurities and dusts contained in the oils.
The other object of the present invention is to provide an improved mechanism capable of burning used oils after cleaning'c'ontinuously and very safely.
In order to attain the above-described objects, the mechanism of the present invention includes, at major elements, a supply source of the used oil, arrangement for mixing pressured air with the supplied used oil, arrangement for filtering the mixture of the used oil with the air (the first mixture) so as to result a better suspended condition of the air voids in the mixture and a burner element for burning this mixture together with separately supplied pressured air.
DESCRIPTION OF THE INVENTION In a preferred embodiment, filtering of the first mixture is carried out within an oil bath tank connected, via suitable connecting pipes, to the used oil supply source and the burner element.
Further, a rotary mixer Y may desirably mounted within the oil bath tank so as to assist the filtering operation. When such rotary mixer is disposed inside the oil bath tank, pressured air may be positively supplied into the first mixture so as to bring about a better An inner cylinder 8 having a perforated peripheral wall is fixed mounted inside the oil bath tank 6 and a rotary wing 7 is pivotally mounted inside this inner cylinder 8. Spacedly encircling the inner cylinder 8, an outer cylinder 14 is fixedly mounted inside the oil bath tank 6 also. This outer cylinder 14 is also provided with perforated peripheral wall.
A nozzle 5 is arranged outside the oil bath tank 6 with its mouth opening inside the inner cylinder 8 and is connected to the pneumatic pump 4 which is arranged outside the oil bath tank 6 also. The used-oil supply pump 1 is connected to the nozzle 5 by way of a connecting pipe 2 which runs through the interior of the oil bath tank 6. A suitable heater 3 is disposed inside the oil bath tank 6 and the connecting pipe 2 runs through the oil bath tank 6 in contact with this heater 3.
A filter box 10 having a perforated wall is also mounted inside the oil bath tank 6 and is connected to the cleaned-oil discharge pump 11 which is located outside the oil bath tank 6.
The burner element 9 is also located outside the oil bath tank 6 and is connected to the pneumatic pump 4 and is connected to the pneumatic pump 4 and the cleaned-oil discharge pump 11 by way of suitable pipe lines.
A rotary mixer 12 is disposed inside the oil bath tank 6 and is provided with multiple wings of perforated structure. The center shaft of the rotary mixer 12 has a cylindrical structure and its internal cavity communicates with perforations of the wings. The internal cavity of the center shaft further communicates with a pipe line which is branched from the pipeline which connects the burner element 9 with the pneumatic pump 4. The oil bath tank 6 is further provided with a suitable level detector 13 and an air discharge valve 15. Further, inside the oil bath tank 6, the rotary mixer 12 is spacedly encircled by a perforated wall 16.
The used oil, e.g., the oil used for cleaning of the machines will be firstly supplied to the nozzle 5 through the connecting pipe 2 by the used-oil supply pump 1. During this transmission, the viscosity of the used-oil from the used-oil supply pump 1 is suitably adjusted by the heating operation by way of the heater 3 around which the connecting pipe 2 runs encircling. As is already explained, the nozzle 5 is connected to the pneumatic pump 4 and is supplied air therefrom. Therefore, the used-oil supplied from the used-oil supply pump 4 is mixed with the pressured air supplied from the pneumatic pump 4 within the nozzle 5. Thus formed mixture of the used-oil with the air is then introduced into the interior of the inner cylinder 8 and collides against the rotary wing 7 so as to cause a rotation of the latter. Thanks to the collision against the rotary wing 7, the air voids contained in the mixture of the used oil with the pressured air are converted into further finer particles. Thus formed mixture of the pressured air with the oil is then forced to permeate through the perforated wall of the inner cylinder 8 and that of the outer cylinder 14 and the air voids contained in the mixture are further converted into further fine particles. The mixture of thus converted air voids of finer particles with the usedoil is then discharged into the interior of the oil bath tank 6.
Inside the oil bath tank 6, the excessive amount of air is discharged therefrom through the air discharge valve l5 and the interior of the oil bath tank 6 is maintained at an atmospheric pressure condition.
As is already explained, the rotary mixer 12 is provided inside the oil bath tank 6 and, thanks to the mixing action by this rotary mixer 12, the air voids contained in the mixture is further converted into further finer particles. Concurrently with this, further number of air voids are created within the mixture. It was already explained that the wings of the rotary mixer 12 are of perforated structure and the perforations are communicated with the pneumatic pump 4 by way of the center shaft of the rotary mixer 12 and the piping connecting the interiors of the internal cavity of the center shaft with the pneumatic pump 4.
The mixture of the oil with thus suspended air voids is then discharged outside the oil bath tank 6 by the operation of the cleaned-oil discharge pump 11 through the filter box 10. When the mixture passes through the filter box 10, the suspending air voids are converted into further finer particles and useless impurities contained in the mixture are filtered by the filter box 10. Thus discharged cleaned-oil containing numerous fine air void particles is then pressuredly supplied to the burner element 9, the cleaned-oil thus supplied in the pressured condition is then compulsorily mixed with the pressured air supplied from the pneumatic pump 4 and the new air-oil mixture thus obtained is then used for burning.
Because the rotary mixer 12 is spacedly embraced by the perforated wall 16, the air voids, which have been converted into finer particle sizes, can be further changed into particles of finer sizes when they pass through the perforations of the perforated wall 16.
The level of the air-oil mixture inside the oil bath tank 6 is always sensed by the level detector 13 disposed to the oil bath tank and, when the level exceeds the prescribed limit the level detector 13 produces suitable signals for stopping the operation of the used-oil supply pump 1 whereas, when the level becomes lower that the prescribed limit, it produced suitable signals for restarting the used-oil supply pump 1. Therefore, the supply rate of the used-oil lowers itself below the prescribed limit, the oil level inside the oil bath tank 6 lowers and, accordingly, the runnings of the used-oil supply pipe 1, the heater 3, the rotary mixer 12 and the cleaned-oil discharge pump 11 are simultaneously stopped so as to intercept the continuous processing of the used-oil through the burner arrangement.
Although the rotary mixer 12 is accompanied with the perforated wall 16 which spacedly embracing it in the case of the exemplified embodiment a suitably designed net surface can be used instead of the perforated wall 16. Further, such wall of oil-air mixture permeable nature can be omitted when the air void contained in the oil-air mixture can be converted into finer particles by the combined filtering effect of the walls of the inner and the outer cylinders 8 and 14.
Further, although the inner cylinder 8 is spacedly embraced by the perforated outer cylinder 14, in the case of the exemplified embodiment the latter may be omitted when the air voids can be sufficiently converted into finer particles only when they pass through therfierforated wall of the inner cylinder 8.
e level detector 13 is given in the form of a buoyant ball in the case of the exemplified embodiment, this structure can be substituted by any other level detector of known type.
Further, the heater 3 is wound around by the connecting pipe 2 in the exemplified embodiment, the connecting pipe 2 may be given in the form of a straight pipe wound around by the heater 3 also. Any known type of heating arrangement can be applied for this purpose.
