  • ABSTRACT An automatic pneumatic pumping system of the type using two or more pumping tanks which are filled in alternate sequence with liquid from a common source and are alternately purged by air pressure so as to effect a continuous and uninterrupted flow of the liquid into a common discharge line, wherein exhaust pumping air is used to create additional head within the liquid supply tanks and the creation of vacuum is used for system and auxiliary use.
  • a preferred application of the system to marine vessels, for example a barge, is described (FIGS. 2-5), along with two special valves, a cargo valve oftop hat" design (FIG. 6) and a cargo inlet feed valve of a two-port wafer type (FIGS. 7A-C).
  • the present invention relates to an automatic pneumatic pumping system of the type using two or more pumping tanks which are filled in alternate sequence with liquid from a common source and are alternately purged by for example air pressure or other pumping fluid so as to effect a continuous and uninterrupted flow of the liquid into a discharge line and relates to its revolutionary application to marine vessels, e.g. barges, which carry liquid, slurry and certain dry types of bulk cargo.
  • pneumatic as herein used includes all types of pumping fluids or gases and not just compressed air and the term liquid" includes slurries and the like.

  • the basic system consists of for example two pumping tanks P and S, connected together by line 4 which is further connected by liquid feed line FL to the bottom of the liquid supply tank 42.
  • Flow from the liquid supply tank is hand controlled by liquid feed valve 3, while flow into the pumping tanks is automatically controlled by liquid inlet valves 5, one for each pumping tank, between line 4 and the pumping tanks P and S.
  • An automatic control system causes the required opening and closing of various valves in proper sequence to effect the alternate filling and discharging of liquid by the pumping tanks, that is, the cycle of operation.
  • This control system may be of special design or one of several standard types available; for example it may be electrically or mechanically operated and triggered either by level sensors within the pumping tanks or by a time cycle controller or by both.
  • the control system closes valve 10 to cut off the sup ply of purging air before the tank has been completely emptied. This action is followed closely by automatic opening of initial exhaust valve 15 which permits the exhaust air from tank P to escape through line ll into initial exhaust line 15L which is further connected to line 27.
  • initial exhaust valve 15 which permits the exhaust air from tank P to escape through line ll into initial exhaust line 15L which is further connected to line 27.
  • the initial exhaust air passes along line 29 to an initial exhaust air reservoir tank 32 where the air pressure is maintained at for example 5 lbs. per sq. inch by pressure control valve 30 in line 29. Also connected to tank 32 is pressure control valve 34 which reduces the pressure of the exhaust air it passes to 12 oz. per sq. inch as it continues on through line 34L to the liquid supply tank 42.
  • the effect in the liquid supply tank is to increase the static head in the tank by 12 oz. per sq. inch, about I foot 8 inches additional head, which increases the rate of flow of liquid from the tank and assists in complete emptying of the tank, both important features when viscous liquids are involved.
  • This particular exemplary pressure of twelve 02. per sq. in. is the maximum allowed in some tanks, barges and ships in particular, by certain pressure-vacuum valves, a required permanently installed safety feature on such cargo tanks, not explicitly shown in FIG. 1. Should the initial exhaust air pressure in line 29 exceed 5 lbs. per sq. inch, the excess is released to the atmosphere by pressure control valve 30. The actions just described followed the automatic opening of initial exhaust valve which is shortly followed by automatic opening of final exhaust air valve 14. This latter action admits the final exhaust air, of lower pressure, into line 14L which is open to the atmosphere through line 31L.
  • a second means of producing vacuum can be provided by direct admission of compressed air from line 13 to siphon 26 by an appropriate direct connection (not illustrated).
  • the automatic opening of final exhaust valve 14 is followed shortly by the automatic opening of liquid inlet valve 5 for tank P, permitting the tank to fill with liquid after which valve 5 is automatically closed and the cycle for tank P is completed.
  • the same sequence of operations described for pumping tank P also takes place in pumping tank S but so timed by the automatic control system that, while tank P is filling, tank S is discharging and a continuous and uninterrupted flow of liquid is produced.
  • the cycle of operation can be slowed down or speeded up by adjustment of the automatic control system; however, other factors such as air compressor capacity, size of piping and viscosity of liquid being pumped affect speed of operation.
  • vacuum tank V is directly connected to line 12L which is fur ther connected through stop valve I2 to the common air inlet and exhaust line 11 to pumping tanks P and S.
  • line 12L is also connected through stop valve to line 25L. This permits use of the vacuum as a suction pump without the complexities of an independent power drive and the attendant hazards when handling flammable liquids.
  • the present invention is adaptable for use in a number of different embodiments, all of which would utilize the same basic system and principles of the present invention but with appropriate changes in layout, piping, etc. as required.
  • the safe pumping system of the present invention could well replace much of the hazardous pump room equipment.
  • Barge Embodiment In the preferred embodiment for use on barges, the most active components of the system are located in the barge pump room which is usually near the forward end of the barge.
  • the room extends across the barge, averaging for example about 35 ft. width, l3 ft. depth and 5 ft. along the length of the barge.
  • two cylindrical pumping tanks P and S lie horizontally across the barge, in-line and near the bottom of the pump room.
  • Each pumping tank can be for example about 30 inches in diameter and 13 ft. long.
  • Flanged spool piece 4 connects tanks P and S together and contains other flanged openings to receive cargo through feed lines FL. In barges having no center line bulkhead dividing the cargo tanks, only one feed line oflarger size is used. In general, the cycle of operation and the automatic control system is similar to that described earlier for the basic system.
  • the cargo feed valves 3, as shown in FIG. 6, are located in the bottom 50 of each cargo tank and are of special top hat design to assure complete emptying of all cargo. These valves can be for example about 20 inches in diameter and are hand operated from deck by means of hand wheels 2' and attached reach rods 2, as shown in FIGS. 4, 5 and 6. Where desirable, reach rods 2 may be encased to reduce friction.
  • ports or cut-aways 53 of large size in the bottom of the outer cylindrical top-hat 54 permit free flow of cargo into feed line FL, as shown in FIG. 6. Opening or closing the valve by rotating the hand wheel 2' and attached reach rod 2 raises or lowers the inner cylindrical piston 51, to which the seating disc 44 is attached.
  • Reach rod 2 is provided with a hollow center flow line 61 which includes a bottom orifice 62 and a top orifice 63, all of which allows any fluid trapped above the inner cylindrical piston 51 to be expelled out the top orifice 63 into the cargo tank.
  • the amount of vertical travel can be for example about 5 inches.
  • the seating surface may be chamfered metal-to-metal as shown, and/or an enlarged diameter disc grooved for a resilient O-ring near the perimeter may be used to form a tight seal against the seat flange 45 shown.
  • FIGS. 7A-C show details of these valves which can be for example about 30 inches in diameter and can be of for example a twoport wafer type as illustrated or otherwise, as desired.
  • the valves 5 can for example be installed in the flanged circumferential connection between the pumping tanks and spool piece 4, thus affording good fastening and easy access to the valve and its automatic air actuator 52.
  • Full opening or closing of the two-port design illustrated requires of rotation of the wafer 46; both operations being so timed in the cycle that minimum pressure is on the valve 5.
  • Steel springs 47 shown in FIG. 7A, exert a constant pressure in line with the pumping pressure for holding the valve on its seat.
  • the air actuator 52 and the drive shaft 48 are supported by sets of trunions 49.
  • the active seating parts or surfaces of the valve that experience wear in normal operation can be reversed to bring fresh unworn surfaces into action, thus prolonging the life of the valve.
  • the cargo feed lines FL can be of for example l4 inch size and are enclosed by for example a concentric 16 inch steam heating line or jacket HL, as shown in FIGS. 3 and 5. Steam for heating viscous cargoes is sup plied through line 40 and controlled by hand stop valves 41 to each cargo tank, as shown in FIGS. 2, 3 and 5. Additional heating capacity, if needed, is available through separate heating coils, not shown but available as a standard item of equipment. Since the energy for heating cargo is lost, no more heating should be done than that necessary to make the cargo pumpable. Rather than heat all the cargo in the tanks, the heating system illustrated has been designed to heat only the cargo being pumped.
  • the pumping tanks P and S may be jacketed for introduction of heat to assure free movement of the inlet cargoes valves 5.
  • the present invention has demonstrated marked advantages over conventional pumps in handling viscous products or products that become viscous in low ambient temperatures. For example, during a test in the case of heavy lubricating oil (Bright Stock) for making greases, the amount of heating necessary to make the cargo flow was much less than would be required with conventional pumps. In fact, the cargo from the pumping tanks was still so viscous as to resemble sausage as it was discharged.
  • Bright Stock heavy lubricating oil
  • the automatic control system actuates the closing of air inlet valve for tank P.
  • the ACS acts to open the initial exhaust air valve for tank P.
  • the ACS causes the final exhaust air valve 14 for tank P to open.
  • the ACS ac tuates the cargo inlet valve 5 inside tank P causing it to open for about 4 seconds, thus admitting cargo to fill tank P.
  • the ACS causes the cargo inlet valve 5 to close and, about one second later, the compressed air inlet valve 10 to tank P to open.
  • the latter action admits compressed air through line 11 and stop valve 6 to tank P which causes the cargo to be purged out through the bottom of the tank into cargo discharge line 18 and on through check valve 19 to the common cargo header line 20 on deck.
  • From the cargo header line the cargo can be directed to port or starboard by use of stop valves 21.
  • the elapsed time from the near empty or cutoff stage to the time when tank P has been filled and compressed air admitted is 7 seconds. This leaves 7% seconds for the purging operation, or a total of fifteen seconds to finish the cycle.
  • tank P also takes place in tank S but so timed by the ACS that while tank P is filling tank S is emptying and a continuous and uninterrupted flow of cargo is produced.
  • the complete cycle for both tanks occurs, at the rate assumed, every l5 seconds or 4 times a minute which would result in a pumping rate of about 3500 barrels an hour.
  • an exemplary vacuum of 20 odd inches of mercury is created in vacuum tank V by the initial exhaust air, and an exemplary air pressure of 5 lbs. per sq. in. is maintained in tank 32 by pressure control valve 30 in line 29. From this point on changes are introduced in the manner of handling the exhaust air for the barge embodiment as compared to the basic system.
  • a connection to tank 32 permits exhaust air to pass through flame screen 33 and on through pressure control valve 34 which reduces the pressure of the air it passes to 12 oz. per sq. in. as it continues on into line 34L.
  • This line leads to the cargo tanks where the effect is to increase the static head in these tanks by about 1 foot 8 inches, which assists in complete emptying of the cargo tanks and, in case of viscous cargoes, further assists their movement from the tanks.
  • pressure-vacuum valves limit the air pressure in the tanks to an exemplary l2 oz. per sq. in. Should the pressure in tank 32 exceed 5 lbs. per sq. in., pressure control valve 30 in line 29 releases the excess through line 31L to scrubber tank 31.
  • This tank serves to remove moisture and particulate matter from the exhaust air before it is discharged to the atmosphere through flame screen 35.
  • Flame screens 35 and 33 are both designed to provide easy access for inspection and, if necessary, cleaning.
  • Final exhaust air valve 14 opens automatically shortly after initial exhaust valve 15 and the final exhaust air passes through line 14L directly to scrubber tank 31, where the action is as before.
  • vacuum may be produced by direct admission of compressed air from line 13 to jet pump or aspirator 26 by opening stop valve 17 and admitting the air through line 27.
  • an important use on barges is in evacuating the bilges. Barges in service commonly have I to 4 or more inches of bottom sediment, oil and water in their bilges.
  • the present invention is well adapted for use as an onboard built-in tank cleaning system to meet this problem.
  • the cleaning procedure, type of solvent used and other details will vary with the product to be cleaned from the tanks. Whatever method is required, this invention lends itself well to a procedure whereby cargo tanks are cleaned.
  • the cleaning solution is taken out by the pumping tanks and stored in either the scrubber tank 31, the exhaust air tank 32 or the vacuum tank V, where it is held for reclaiming or other disposition.
  • FIGS. 2, 3, 4 and 5 all stop valves in the system are closed.
  • the sea cock 1, shown in FIG. 5, is opened; this admits water to the forward ballast tank 59 (note FIG, 5), causing some increase in draft of the barge forward where the pump room is located.
  • the cargo valves 3 in all cargo tanks are opened through the use of hand wheels 2' and reach rods 2 on deck.
  • the stop valve 6 in air inlet and exhaust line 1] is opened to both pumping tanks.
  • the starboard stop valve 21 in cargo header line 20 on deck is opened to direct discharging cargo in the desired direction.
  • the automatic control system (ACS) is actuated by push bottom and compressed air is admitted to air line 13. The system will then automatically start operation.
  • ACS automatic control system
  • Loading of liquid cargoes on present barges is usually accomplished through a permanently installed loading line on the deck of the barge from which the cargo experiences a free fall as it drops into the cargo tanks. This introduces some hazards, particularly in the case of flammable or otherwise dangerous cargoes.
  • the cargo will be loaded through lines 20, 18 and FL with hand control by means of stop valves 21, and individual cargo tank feed valves 3. No free fall is involved and there is no need for a loading line on the deck of the barge.
  • the operation of the present invention is quiet and unstrained as it smoothly delivers large volumes of cargo.
  • barges and ships equipped with this system have an expanded usefulness and versatility in meeting a wider variety of missions.
  • the efficiency and reliability of the air purging operation as compared to conventional pump systems with their frictional, mechanical and energy losses is clear. Many hazards of conventional systems are eliminated without introduction of new hazards.
  • Environmental pollution is reduced by elimination of the diesel engine exhaust from each barge and by a clean system that also provides for handling and keeping normal pollutants aboard the vessel.
