OIL RECLAIMER March 12, 1957 Filed March 14, 1955 2 Sheets-Sheet l March 12, 19.57
Filed March 14, 1955 2 Sheets-Sheet 2 2,785,109 ou. RECLAIMR William CfSchWalge, Prairie View, Ill. Application Maren 14, 195s, serial No. 494,164 12 claims. (ci. 19a-1s) This invention Vrelates to an oil reclaiming device; and
' in particular it relates to an oil reclaiming 'device which is 'adapted for vinstallation in modernvrnotor vehicles.
It'h'a's been well known for many years that the conventionalbil filters used in internal combustion engines are of only limited value because they provide'no means of removing light diluentsor 4water from the`oil. This requires some sort of a vaporizing unit in addition to the filter.
The 'principal object of the present invention isto provide anoil reclaiming device which is adapted for installation in modern passenger vehicles in which the exhaust manifold is so positioned that it can not be reached Vvas a source of'heat for operating the vaporizing mechanism ofthe reclaimer.
A further object ofthe invention is to provide a reclaimer in-which part of the oil flow from a filter comany heating means'for the vaporizing unit. This is accomplished in one embodiment of the invention by extending an air vent lto a position close to the vaporizing memberlto conduct hot air from the air stream outside the reclaiming device over the vaporizing surface ofthe vaporizer.
A further object of the invention is to provide an oil reclaimer in which the Vaporizing chamber is of very small height,'so thatthe overall height of a unit including a` filter and a vaporizing chamber thereabove is little greater than the height of a filter alone.
A further object of the invention is to` provide a single basic structure with which leither an electrically heated vaporiiing unit or an air stream heated vaporizing unit may be employed depending upon the lo'cal'conditions.
The invention is illustrated in a preferred and an alternative embodiment in the accompanying drawings in which:
Fig 1 is a central vertical sectional view of the preferred embodiment of the invention;
Fig. 2 is arsection taken as indicated along the line-2 2 of Fig. 1; and Y Fig. 3 is a fragmentary section of the vaporizing chamber of an oil reclaimer provided with the alternative form of vaporizing Vdevice heretofore referred to.
Referring to the drawings in greater detail, and referring first to Fig. 1, a reclaimer unit has a deep drawn sheet metal body 5 which has a filtercompartment l6 in its lower portion and a vapo'rizing chamber 7 in its upper en d portion. At the bottom of the filter compartment 6 is a boss 8 to receive a central oil inlet'pipe9 which extends axially through the entire body 5 from bottom to top, and is connected at its lower end to Va fitting 10 for an oil inlet 11. An oil drain pipe 12 is provided,
United States Patent Patented Mar. 1'2, 1957 with a suitable valve. The filter compartment 6 is shown in the drawings as filled with loose filter material 13;
but it is obvious that `a filter cartridge could be substi-v tuted for the loose filter material if desired. The oil inlet-pipe 9 has a pair of openings 9a to admit oil to the filter chamber 6 immediately Vabove the nipple 8, and oil passing through the openings 9a may ow through the holes in a foraminous plate 14 and upwardly through the filter material 13. Above the plate 14 are additional .holes 9b through which oil may pass into the-filter maferial, and still farther up are holes 9c and 9d. If desired the pipe 9 may be provided with radial bafiies 15 and 16 to force the oil to flow outwardly through the outer portion of the loose filter material 13. Obviously the 'arrangement of bafiles could not be used in conjunction with a filter cartridge unless the bafes were an integral part of the cartridge instead of being fastened to the oil inlet pipe 9.
On top of the filter material 13 is a felt pad 17 held down by a perforatefilter plate 18 yand a solid diverter plate 19 which has radial ribs 19a bearing on the lter plate to'leave a space 20 between the plates. Thus the plates 18 and'19, spaced by the ribs 19a, in effect form a hollow floor for the vaporizing chamber '7. The filter plate 13 is of smaller diameter than the felt pad, so that the margin of the pad is elevated as seen in Fig. l. lust below the level of the felt pad 17 the oil inlet pipe 9 is provided with aplug 21 which prevents any oil from passing directly through theV oil inlet pipe into the vaporizing chamber 7.` Thus all the oil mustA pass through "the 'filtermaterial andthrough the felt pad 17; and'from the space 20 between the plates the oil may pass through oil return holes 22 into a vaporizer feed portion 9e of the oil inlet pipe 9. Immediately above the diverter plate 19 are small oil by-pass holes 23 through which some oil may pass to the top of the diverter plate, While near the upper end of the vaporizer feed portion 9e are oil feed holes 24 for permitting oil to tiow onto a vaporizing unit, indicated generally at 25. Thus, part of the oil may pass through by-pass holes 23 and flow to an oil return line 26 without passing over the vaporizing unit 25, while the balance of the oil iiows through the oil feed holes 24 onto the vaporizing unit.
, Referring now to Figs. 1 and 2, the vaporizing unit 25 has a plurality of legs 27 which stand on the diverter plate 19, and a frusto-conical sheet metal top 28 which, as seen in Fig. 2, has concentric corrugations 29. The
top 28 acts as a vaporizing surface over which Oil from the feedholes 24 may fiow in a thin film. Beneath the vaporizing top plate 2S is an electric heating coil 30 below which is 'a packingconsisting of any suitable heat resistant material 3,1 .such yas asbestos. The vaporizing unit 25 is firmly held down on' the diverter plate 19, and the diverter plate and filter'plate 1S are pressed Vagainst the felt pad ,'17 byV means of a wing nut 32 whichscrews onto a thread yon the vapori'zer feed portion 9e of the oil inlet pipe and bears on a washer 33 to clamp the vaporizing unit in place.
Surmounting the heating chamber 7 is a top closure 34 which has a b'ossSS'sui-roundi'ng a `'central opening to accommodate a Wing` nut'36 which screws ontoa' projecting stud 37 which plugs the top of oil inlet pipe 9 just above oil feed holes 24. The'hating coily Si) has a' pair of `rigid electric contacts 38`Which extend upwardly `in line'with anropening 39 finthe closure 34, and a pair of armored cables 40 secured to the 'contacts extend Vupwardlythrough the opening 39 and are surrounded by an insulating plug 39a through which the `cables '49 may slide when the closure 34 isremovedfrom the unit.
Exteriorly of the closure 34 the .cables arewired into 'a'sealed thermostat unit 41 which is mounted in anop'ening in the closure 34 so that its inner face is inside the chamber 7; and wires 42 and 43 connect the thermostat louter end portion 45 turned horizontally toward the front of the vehicle so as to take air from the air stream passing around the oil reclaimer. The inner end 46 of the inlet pipe 44 is directed at the vaporizing unit 25 so as to assure rapid removal of evaporated materials from the `vicinity of the vaporizing surface 28. Preferably a small ne mesh dust filter screen 47 covers the front of the'air inlet pipe 44. Cooperating with the air inlet 44 is an air outlet 48 which has its outer portion 49 directed rearwardly so that the air stream passing thereover helps sustain a rapid air iiow through the vaporizing chamber 7 to remove vaporized impurities.
The operation of the device is believed to be obvious from the foregoing description. After oil passes through the filter material 13 and the felt pa'd 17 it reenters the vaporizer feed portion 9e of the oil inlet pipe 9 through the openings 22, and passes upwardly through said portion 9e where some of it escapes from the pipe through the by-pass holes 23 and some passes through the feed holes 24 and spreads in a thin film over the vaporizing surface 28 of the vaporizing unit 25 so as to have the low boiling diluents and water removed from it. The thermostat 41 is set to maintain the temperature within the evaporating chamber 7 no higher than about 250, so that the oil does not become excessively hot. Oil whichrows over the vaporizing unit 25 and also the oil which flows through the by-pass 23 is discharged on top of the diverter plate 19 and out to the oil return line 26.
Referring now to Fig. 3, the second form of the invention is exactly like the rst embodiment except for the fact that it has an unheated vaporizing unit 125.
The vaporizing unit 125 in the present form of the device consists of a foraminous, annular supporting wall 127 within which is mounted a plurality of parallel, rforaminous, frusto-conica1 plates 128. The units 25 and 125 are exactly the 'same height and diameter so that they may be interchanged in the same vaporizing chamber depending on the local conditions which are encountered in the use of the oil reclaiming device. Y
The second form of the invention is particularly adapted for use in the hot southwest parts of the United States during the summertime when the hot, dry air entering the air inlet pipe 44 is quite adequate to vaporize any undesirable diluents or water from the oil passing over the vaporizing surfaces 128. Because of the lower temperatures employed, the vaporizing area of the alternative unit 125 needs to be substantially greater than that ofthe electrically heated unit 25, and this is accomplished by employing the plurality of foraminous plates 128 which permit the oil to ow from one plate to another.
