Abstract
. ABSTRACT OF THE DISCLOSURE
A used lubricating oil treatment apparatus is provided in which filters, heat exchange means, a vaporiser unit, pumps and other necessary equipment are all contained in a wheeled cabinet.
The oil to be treated is pumped through a warming heat exchanger, a first filter, a vaporiser unit, and further filters, after which appropriate additives are mixed into the decontaminated oil in a mixing tank. A vacuum is maintained on the vaporiser unit to exhaust the vapours from it via the heat exchanger and a condensate tank.

Description
3~
.: i This invention relates to the processing of used lubricating oils for the purpose of reconditioning such oils for re-use.
~uge quantities of lubrica-ting oils are continually being discarded after use, especially at automobile garages whlch have to dispose of large amounts of used sump oil from motor vehicles.
Some of this oil is processed for re-use but for that purpose it has to be collected and sealed in drums and returned to an oil company where it is put through large-scale industrial oil-tre~tment plant. This gives the individu~l automobile service station or oil user very little incentive to save the oil. It is therefore an object of the inver~+ion to make the processing of lubricating oils for re-use a more widely practised activity.
According to the present invention, there is provided a lubricating oil treatment apparatus, comprising pumps, filters, heat exchange means and a vaporiser unit operating under vacu~n, embodied in a self-contained movable module. By thus making it possible i for individual service stations and oil users to possesstheir ¦ own units for treating the oil, the reconditioning of used oil~ , ., ~'1 becomes a considerably more attractive proposition.
One arrangement according to this invention will now be described by way of example and wqth reference to the acccmpanying ,i , drawings, in which:-~' Figure 1 is a front pictorial external view of the apparatus to be described, , . . .
Figure 2 is a rear pictorial view with the covers removed, and Figure 3 shows the flcw sheet of the apparatus.
,~' While the apparatus to be described is mainly intended for !
~ 2/
l , i! .
treating used sun~ oil from mo-tor vehicles, it can also be employed for industrial lubricating 3ils.
Referring to Figure 3, oil to be treated, e.g. from a drwm 10 containing contaminated oil, is pumped into the apparatus through an inlet valve 11 via a 60 mesh Y-type strainer 12 by an oil input pump 13. The discharge of the pump passes through a relief valve 14 I into a heat exchanger 15 where it is warmed by heat exchange with j vapour drawn from the top of a vaporiser unit to be subsequently described. On leaving the heat exchanger 15, the oil passes through a flow meter 16 and then -through a prel-iminary 5 micron filter 17 after which the warmed oil enters the vaporiser unit 18.
In the vaporiser unit 18, the oil is heated to a temperature to dr;.ve off water and volatiles and this operation is assisted ¦ by a vacuum pump 19 which pulls a vacuum on both the vaporiser unit¦ 15 an~ an associated condensa~e tank 20. The vapours drawn off from the vaporiser unit 18, after passing through the aforementioned heat exchanger 15 to warm the incoming oil, enter the condensate tank 20 where condensate settles out, and are then exhausted through ~~ the vacuum pump 19. m e condensate tank may be provided with a sight level gauge to assiæt an operator in determining when, periodically, , the vacuum should be released and the condensate drain 22 opened.
Also, a level indicator may be fitted to trigger off an audible alarm if this service attention is neglected and the condensate ~ level in the tank rises too high. The vaporiser unit 18 is equipped !''~' 25 with an electric heater 24 having an associa-ted temperature control and indicator instrument 23. m e vaporiser also has a sight level gauge 21.
~i .
., ~ .,t3~ 6 After leaving the vapori.ser Ullit 18, the oil is punped by a circulating pump 25 in succession thl70ugh two e~rth filters ' 26 and a final 0.5 micron filter 27 before discharging into a ta~
1 28. Between the circulating pump 25 and the first ~ilter 26 the oil line includes a non-return valve 32, with a pressure relieP valve 33 immediately upstream o-L the valve 32. Immediately downstream of the non-return valve 32, a changeover valve 29 enables the oil flow to be directed, at start-up, into by-pass line 34 instead of through the filters 26, 27. The oil bypass line 3A, and also the relief line I 10 35 for the pressure relief valves 14 and 33, deliver back into ¦ the oil drum 10 fron which the oil to be processed is drawn.
The ta~ 28 i.s a mixing tank in which oil additives supplied through a line 36 are mixed with the decontaminated oil from the filters.
A heater 37 heats the oil in the tank 28, and a float valve 38 supplies a sig~al to stop the apparatus from delivering oil into the tank 28 when the level in the tank rises to a predetermined high level. An output pump 39 pumps the finally treated oil from the mixing tank ~ 28 into a coilecting drum 40; a changeover valve 41 enables the output of the pump 39 to be returned to the tank 28 for mixing instead of being discharged through the output line 42.
Referring now to Figures 1 and 2, the apparatus is housed in a `~ whééled cabinet 30 with a console display of indicator la~ps and gauge readings. Instruments are provided to disp]ay the following:
oil reading measured at the flow meter 16; pressure differential across ~¦, 25 t~e filter 17; pressure differential across the filter 27; temperature ¦, of the oil in the vaporiser unit; vacuum gauge reading. Control of '!, the apparatus is by means of a push button control panel 43. The ,., ., .
