APPARATUS FOR USE IN CLEANING THE INTERIORS OF BARRELS Falmouth, Maine, assignor to The Portland Company, Portland, Maine, a corporation of'Maine Application April 29, 1953, Serial No. 351,771 18 Claims. (Cl. 134-56) This invention relates to apparatus for use in reconditioning the interiors of barrels, which term, as used herein, includes other containers having relatively small openings.
In Letters Patents of the United States No. 2,147,247, dated February 14, 1939, and No. 2,240,364, dated April 29, 1941, apparatus and method, respectively, are disclosed by which the interiers of barrels may be eflfectively reconditioned.
The reconditioning of barrels is economically desirable but is made difficult by the fact that their construction usually is such that their interiors cannot be completely drained by gravity and, as a result, the drying of the interiors presents problems. In accordance with the above mentioned patents, the reconditioning of barrel interiors, which usually consists in washing, rinsing, and drying them, as effected by the use of a spray tube insertable into a barrel through its bung hole and evacuating means Whose suction tube is similarly positioned with its intake end disposed in a pocket established by tilting the barrel to make the pocket downwardly accessible. Each fluid, such as washing and rinsing fluids and air, is delivered to the spray tube. In order that liquids may be employed without any appreciable accumulation thereof in the barrel, the flow through the suction tube is so balanced relative to the flow to the spray tube that the exhaust stream through the suction tube is at least equal to that of the delivered liquid. As a substantial part of the fluid delivery system is common to the vari ous sources, the same relation also existed, in the case of air, between the delivery and exhaust air streams.
The present invention is directed to an improvement in the drying of the interiors of barrels with the objective of drying them more completely in a shorter time. In accordance with the invention, this objective is attained by maintaining the above indicated relationship between the delivery and exhaust streams of liquid but, in the case of air, changing the relationship therebetween to ensure the discharge of air through the bung hole.
Where the apparatus entails a fluid delivery system of which a substantial part is common to all sources, control means are necessary to enable the desired fluid streams to be automatically established and these may include, for example, thermostatically perated valves, and pressure or volume regulating devices.
, In the accompanying drawings, there are shown illustrative embodiments of the invention from which these and other of its objectives, novel features and advantages will be readily apparent.
In the drawings:
Fig. 1 is a partly sectioned fragmentary view of apparatus in accordance with the invention in which pressure regulating means are employed to control the air streams;
Fig. 2 is a like view of a different embodiment in which the control of the streams is effected by the adjustable orifices;
Fig. 3 is a fragmentary section, on an enlarged scale, taken along the indicated lines 3--3-of Figure 2;
ICC
Fig. 4 is a generally similar view of another embodiment of the invention in which the control is effected by a thermostatically operated valve; and
Fig. 5 is a view illustrating a further embodiment of the invention in which the suction tube is connected to a vacuum chamber.
The barrel 10 shown in some detail in Fig. 1 is illustrative in that it has liquid retaining chimes 11 and a bung hole 12 established by the threaded collar 13 projecting interiorly of the barrel to prevent complete gravity drainage. tilted position with its bung hole 12 disposed upwardly, a fluid collecting pocket 14 is established that is accessible downwardly therethrough.
Fluids are delivered against the interior ofv the thus positioned barrel as by means of a spray tube 15 dimen-' sioned to be inserted through the bung hole 12 while liquids are simultaneously exhausted through a suction tube 16 also extending downwardly through the bung hole 12 but with its open end extending downwardly into the pocket 14.
Preferably the suction tube 16 is of such size that it may extend freely through the spray tube 15 whose lower end is sealed thereto as at 17. The suction tube 16, when the barrel 10 is to be rotated while being cleaned, may have, at its lower end, a rotatable bearing 18. I I
The tubes 15 and 16 are shown in Figs. 1, 2 and 4 as connected at their upper ends to an ejector head 19 with the suction tube 16 in communication with the suction chamber 20 with which the ejector inlet 21 and the ejector discharge port 22 are in communication. The spray tube 15 is, for convenience, illustrated as being in communication with a second inlet port 23.
In Fig. 1, the fluid delivery system is shown as consisting of a washing conduit 24 in communication with a source of a washing liquid, and provided with a check valve 25, a conduit 26 in communication with a source of rinsing liquid, and provided with a check valve 27, and a conduit 28 in communication with a source of air under pressure, and provided with a normally closed solenoid operated valve 29, a pressure regulator 30, and a check valve 31. While the fluid sources are not shown, it will be understood that each source is adapted to be placed in communication with the system to the. exclusion of the others and it is for this purpose that each source is provided with a check valve. For reasons that will presently be apparent, there is a branch air conduit 32 provided with a pressure regulator 33 and a check valve 34. The pressure regulator 33 is set to. provide for the delivery of a greater volume of air than is established by the pressure regulator 30.. Obviously, two independent sources of air under pressure can be used, if desired.
The conduits above referred to are all in communication with the common supply pipe 35 which is connected to the spray tube 15 via the inlet port 23 and which includes a branch supply pipe 36 in communication. with the ejector inlet 21.
When washing water is used, it flows to the ejector head via the branch line 36 and through the delivery con duit 35 to the spray tube 15. The check valve 27 prevents flow of the washing liquid towards the rinse water source while the check valves 31 and 34 prevent the flow thereof towards the air source. 7 I
When the interior of a barrel is to. be rinsed, the rinse water flows through the delivery conduit 35 to the spray tube 15 and to the ejector via the branch line 36. The check valve 25 in the washing liquid conduit and the check valves 31 and 34 in the air supply conduits prevent the flow of rinse water towards those sources.
When the interior of a barrel is to be dried, the valve Patented Aug. 5, 1958.
When, however, the barrel isin a 3 29 is opened, thus to admit air under pressure through the air lines 28 and 32 to the supply pipe 35 which is furnished with a check valve 37 between the junctions oftheair conduits 28and 32. therewith. The check valve 31 is, opened by the pressure of the liquids when in usev and is adapted to, be closed by the greater pressure in the conduit 35 adjacent the spray tube 15 established by means. of adjustments of the pressure regulators.
At this point, it will be helpful to. note. that when a liquid is to be introduced into the'barrel 10, it is necessary to effectv itswithdrawal through. the suction tube 16 in a stream at. least. equal in volume. tothat delivered to the spray tube 15 to avoid accumulation of liquid therein and the flow from, either liquid source to the spray tube 15 and ejector head 19 is, proportioned to produce such streams. While, during siphoning, there. isusually some variation between the streams, the desired objective is that the exhaust stream be capable, of handling all the delivered liquid, during the delivery cycle. The pressure regulators are set, however, to ensure the delivery of an air stream into the barrel of greater volume than the stream through the suctionv tube 16 thus to ensure the discharge of some. air through the bung hole.
In the embodiment of the invention shown in *Fig. 2, the washing liquid conduit 38 is, provided with a check valve. 39-, the rinsing liquid conduit 40 has a check valve 41, and, the air conduit 42 has a pair of check valves 43 and 44.. It also may be provided with anadjustable orifree. 45. Those fluid supply conduits join a supply pipe 46 in communication with the ejector inlet 21. The supply pipe 46 has a branch, 47 in communication with the spray tube 15 via the inlet port 23. Intermediate its check valves 43 and 4,4, the. air conduit has a branch 48 connected to'the T 4? with which the branch supply pipe 47 is provided.
On, opposite sides of the T 49 are adjustable orifices 50 and 51. The adjustable orifices 45, 50 and 51, as shown in. Fig. 3, may consist of a boss 52 threaded to receive the partial plug 53. The orifices 45, 50 and 51 areso adjusted as to allow a larger stream to flow through the orifice 51 than through the orifices 45 and 50 thus to ensure that, when liquids are in use, the exhaust stream through the. suction tube 16, is at least of the volume of the stream delivered through the spray tube 15 and, when, air i'sused, that the delivered volume of air is sufficiently great to cause air to flow out through they bung hole of the barrel.
With reference, to Fig. 4, there is therein shown a washing: liquid conduit 54 provided with a check valve 55, a rinsing. liquid conduit 56 having a check valve 57, and an air, conduit 58 also including a check valve 59. These conduits are all in communication with the supply pipe 60 connected to the ejector inlet 21 and including a branch; pipe 61 connected to the inlet 23 thus to deliver fluids to the spray tube 15.
At the junction of the lines 60 and 61, there is a chamber 62 for the adjustable thermostatically actuated valve 63. The valve 63 is adjusted to close partially in response to the heat of the washing or rinsing liquid thereby to provide the correct balance between the delivery and exhaust liquid streams and to open, when air is used thereby, increasing the flow of air to the spray tube 15.
In the embodiment of the invention shown in Fig. 5, there is shown evacuating means consisting of a suction tube 64 connected by the conduit 65 to a vacuum chamber 66. The spray tube 67 may be in the form of a sleeve suitably sealed at its ends to the suction tube 64.
The conduit 68 from the washing liquid source has a check valve 69, the conduit 70 from the rinsing liquid source is provided with a check valve 71, and a check valve 72 is also located in the conduit 73 for air under pressure. Communication between the conduits 68, 70 and 73 is efiected by means of the pipe 74 to which they are connected.
As, illustrative of means to establish, the desired relationship in the volume of the delivery and exhaust streams, there are shown valves 75 and 76 in the liquid conduits 6S and 70, respectively, which are operable to provide that the volume of the potential exhaust stream is at least equal to that of any liquid stream that is delivered into the barrel. The valve 77 in the air conduit 73 illustrates control of the air source to ensure that the volume of delivered, air is greater than the volume of the exhaust stream.
Itwill thus be apparent that by these or like means, the invention makes possible the treatment of the interior of a barrel by a liquid or liquids without appreciable accumulation of liquid therein. This results because the volume of the exhaust stream is at least equal to that of the delivered stream. At the same time, the invention makes possible more eflicient and complete drying of the interior of the barrel since it provides for a change in the relationship between the delivery and exhaust; air streams to ensure the discharge of air through the bung hole carryingmoisture therewith and improving the action. of the evacuating means.
