APPARATUS FOR REMOVING OIL'AND SEDIMENT IN BULK FROM SHIPS.

Application filed April 6, 1922. Serial No; 550,246.

New York, have invented a new and Improved Apparatus for Removing Oil and Sediment in Bulk from Ships, of which the following is a full, clear, and exact description.

moving sediment from oil burning steamers and particularly to means which will'soften and more or less liquefy .the sediment in order that it may flow more readily through discharge pipes.

The invention further refers to an improved. construction wherein a vacuum is used for drawing oil and sediment therefrom to a discharge oint assisted by jets of air and steam which aerate and break up to a large extent the sediment so that it may be readily lifted to a comparatively high point and discharge into a suitable receptacle.

The objectof the invention is to provide an improved construction and method of extracting oil and sediment from oil burning ships in a minimum time and at a minimum expense.

Another object of the invention is to provide a convenient and easy method of extracting in a short time large quantities of sediment from oil burning ships, oil carrying ships and ships of anykind, through the use of a suction and heat supplied to the sediment.

.A further object, more specifically, is to provide means for removing sediment from oil burning ships wherein a structure is presented which will thoroughly break up the sediment in addition to aerating the same.

In the accompanying"drawings Figure .1 is a transverse sectional view in diagram of an oil burning ship, a sediment removing apparatus being shown in connection therewith.

Figure 2 is a diagram in top plan of the ship shown in Figure 1 and the arrangement of oil carrying compartments. Figure 3 is a detail enlarged sectional view showing the arrangement of heating apparatus and elevating means associated therewith.

This invention relates to devices for re- Figure 4 is a top plan view of the pumping outfit shown at the right in Figure 1.

Figure 7 is an enlarged sectional view through one of the joints of the section pipe shown in Figure 1.

Figure 8 is a transverse sectional view through Figure 7 approximately on line 8-8.

Referring to the accompanying drawings by numeral, 1 indicates an oilburnmg' ship of any desired kind provided with the usual oil burning compartments 2 arranged between the inner and outer shell of the bottom of the ship. In-constructing these compartments openings .3 are usually provided of sufiicient size to permit a person to pass from one compartment to the other and also to permit oil to pass from one compartment to the other. In addition, small apertures 4 are provided at the extreme bottom in the various partitions so that if the entire contents of the compartments are liquid they may readily flow to the lowermost point and, consequently, from one compartment to the other. It is usual for a ship to list somewhat and, consequently, will make a specially low point at .a certain location. By providing the openings 4, the oil may freely flow to that point and may be removed readily from a single point rather than from difl'erent points.

In addition to having the openings 2, it v is customary to have a manhole .or opening at certain intervals over the entire bottom of the ship. Through one of these openings the suction pipe 5 embodying certain features of the invention is inserted as shown in Figures 1 and 3. This pipe may be formed of metal and comparatively still or may be formed of flexible material.

In the present invention it is intended to provide means which will remove any kind of oil or sediment from the bottom of the ship. Where the oil is in a liquid state, the suction provided in pipe 5 will usually produce the desired result but where the matter to be removed is a heavy sticky sediment it is necessary to .liquefy the same. As the sediment is liquefied, it will flow through.

the openings 4 to the lowermost point where the end of the pipe 5 is located and from thence it may be removed as hereinafter fully described. I

In addition to removing from the lowermost point, the pipe 5 may be moved to the different compartments whenever desired so as to thoroughly clean every part of the various compartments.

The suction pipe 5 is connected to a suction outfit 8 located on a fioat 9 or any other suitable support. This suction outfit consists of-tanks 10 and 11 exhausted of air by a suitable pump 12, said tanks being connected together by a suitable pipe in which the valves 13 and 14 are enclosed so that *either compartment may be turned off. Be-

tween the valves 13 and 14 the connecting pipe 15 is connected with the suction pipe 5 so that whenever it is desired to discharge into the tank 10 for instance, valve 13 is opened and the rarefaction therein will cause thematter passing through the pipe 5 to be discharged into tank 10. "When this tank is full, valve 13 is closed and valve 14 opened. This will cause the pipe 5 to dis- 0 arge in tank 11.

In additionto providing suction or rarefaction in pipe 5, said pipe carries a small steam pipe 16 which is supplied with live steam from any suitable source and enters pipe 5 near the point where pipe 5 is connected to the cross pipe 15. The steam pipe 16 is held at one side of pipe 5 by the various plates or washers 17 used as gaskets in connecting the sections of pipe ,5 together as clearly illustrated in Figures 7 and 8.

It will be noted that the gasket or washer 17 is provided with an inwardly extending lug 18 through which pipe 16 passes. Near the entrance or lower end of the pipe, the steam pipe 16 passes out through an opening and then is formed into a loop so that the nozzle or discharge end 19 ma be well within the pipe 5. The location 0 the nozzle 19 may be at any desired point but preferably about half way between the center of pipe 5 and the wall thereof while the nozzle 20 of the air pipe 21 is located simi larly but on the diametrically opposite side of the center as illustrated in Figure 6. The air pipe 21 preferably parallels the pipe 5 exteriorly and is supplied with compressed air from any suitable source, as for instance, from the tank 22 on float 9 which tank is supplied with compressed air from the pump 23. As the jets of air and steam passfrom the nozzles 19, 20 and also as the rarefaction is brought into use, the member 24: begins to rotate whichmember acts as a chopper or beater for breaking up the sediment 1mmediately after it enters the lower part of the pipe 5. The member 24 is formed with a propeller like structure 25, a ring 26 and bearing members 27 which in the present instance consist of balls mounted in a suitable race formed in pipe 5. The reason that it is desirable to break up the sediment is to permit the air and steam to aerate the same and thereby not only lighten the sediment so that it may be more readily lifted but prevent it from sticking against the walls of the pipe 5." It will thus be seen that the sediment is broken up by the beater 24 and then aerated by the steam and air from the jets 19 and 20 while the suction or rarefaction produced by pump 12 acts to lift and convey the broken up and aerated sediment to the tanks 10 and 11 from which it may be removed at any time. It will be, of course, understood that any form of tank with a suction pump may be used without departing from the spirit of the in vention and also any form of means for interposed in the pipes 16 and 21 are turned on. The action of the suction of air and steam will cause the beater 24 to rapidly rotate and, consequently, will thoroughly beat up or finely divide the sediment in the presence of air and steam which naturally produces a form of aeration. When the sediment is in this form, it is more readily lifted and discharged into the tanks 10 and 11 and will not readily adhere to the sides of the pipe 5. When all of the sediment in the given compartment or section of a ship has been removed, the lower end of pipe 5 is shifted to another compartment and so on until the entire series of oil compartments have been cleaned. This aerating of the oil reduces the specific gravity of the oil substance whereby the same may be easily raised and discharged over the side of the ship.

What I claim is 1. The apparatus described, comprising an exhaust tank, means for maintaining a high vacuum therein, pipe connections from said tank to the material to be raised and arranged to transfer said material to said tank through the action of suction produced 1n said pipe by said rarefaction, means for supplying air and steam to said pipe, and
