13 Claims. 1

The present invention relates to apparatus for conditioning containers and more particularly containers in the nature of barrels or the Among the objects of the present invention is to provide a novel device for conditioning containers, such as barrels or the like, expeditiously, economically and effectively.

For some time in the past it has been the practice, particularly in the petroleum field, to make use of barrels for holding oil and the like for one shipment of such goods and to then junk or destroy the same. However, due to present economic conditions, barrels cannot be easily secured and it has become the general practice in the trade to recondition these barrels after use so as to be re-usable again ,and again for shipment of the particular products desired. Because of the nature of the products involved, it has been exceedingly dimcult to condition the barrels for such successive uses and to provide containers which are uncontaminated with the material previously shipped therein and resort has been made to extensive hand operations which, under present circumstances, is exceedingly undesirable and unsatisfactory, as well as making the cost of such reconditioning excessive.

One of the principal objects of the present invention is to provide a novel container conditioning apparatus which can be operated by relatively unskilled labor at relatively low cost for effectively and efliciently treating such barrels or containers to make them suitable for re-use after each shipment. In this aspect of the invention, barrel equipment may be re-used time and again, thus greatly decreasing the cost of shipment of such goods as are particularly found I in the petroleum field.

Another object within the purview .of the present invention is to provide a novel container conditioning apparatus which by simple manipulation is adapted to cyclically treat successive barrels introduced therein through a complete conditioning operation involving, for example, such steps as applying a caustic material to the interior and exterior surfaces of such containers, draining such caustic material from the containers, rinsing the same with wash water, and then causing the containers to be dried by the application of air, or the like, thereto.

In the more particular aspects oi the invention, one object thereof is to provide a conveyor system for the said containers so constructed and arranged as to facilitate the operations above referred to and which procedures involve the supplying of such fluids as are desired for the conditioning operations to the containers by gravity flow, both to the exterior and interior surfaces or the containers. In this connection, the invention further contemplates the application of heated air to the fluid flow into the interior of the containers so as to effectively disperse the same over the entire interior of such containers to assure proper conditioning thereof.

Still another object of the present invention is to provide a novel arrangement for raising the temperature of the conditioning fluids, involving the use of heater tubes adapted to discharge spent gases of combustion into a flue associated with a distributor head for the air such that the temperature of the air is elevated the desired amount.

Still another object of the present invention is to provide a novel housing structure for the containers undergoing treatment, comprising a movable buoyant support for such containers adapted, when in normal initial position or in the absence of fluid within the housing, to dispose the containers in a position inclined toward the entrance to the housing so as to facilitate introduction of the containers therein and to provide for effective draining of the containers, yet which is adapted under the buoyant action oi fluid when in the housing to move such containers into substantially an upright position whereby conditioning fluid efiectively treats the exterior surface of such containers.

The invention further comprehends the idea of incorporating vibrating means for the containers within the housing structure so as to assure dislodgement of material adhering thereto during the conditioning process.

Other objects, features, capabilities and advantages are comprehended by the invention, as will later appear and as are inherently possessed thereby.

Referring now to the drawings, Figure 1 is a top plan View of conditioning apparatus made in accordance with the present invention;

Figure 3 is a fragmentary view in cross section taken in the plane represented by line 3-3 of Figure 1 of the drawings;

Figure 4 is a fragmentary view in cross section taken in the plane represented by line 4-4 of Figure 3 of the drawings; and p Figure Sis a view in cross section taken in the plane represented by line 5-5 of Figure 4 of the drawings.

Referring now more in detail to the drawings,

an embodiment selected to illustrate the present invention is shown as comprising a circular type conveyor 2 formed with a plurality of housing structures 4, each of which is provided with a caster 6 operating over the circular track 8, whereby each of the housing structures may be progressively moved through a conditioning cycle of operation for containers which may be disposed within such housing structures.

The housing structure are interconnected by members I0, apertured as at I2, whereby the conveyor can be rotated as above explained by the introduction of a tool into the opening l2 by the operator. Interconnecting the housing structures at their tops is a fluid receiver ll of annular construction, partitioned as at l6 on each side of the housing structures for a purpose which will be understood more clearly as the description proceeds.

According to the embodiment herein disclosed, the arrangement of the mechanisms is such as to particularly adapt the same for use in conditioning barrels 18, as shown in Figure 3 of the drawings, which are formed with bung-openings, such as 20, disposed in one of the end walls of the barrel and adjacent the chime 22. This type of barrel inherently possesses a structure which is difllcult to effectively condition and accordingly the present apparatus has incorporated therein certain features of construction which facilitate the handling and conditioning of this type of barrel, although it is to be understood that the same may be used for conditioning containers generally.

While reference has been made to the housing structures by the reference numeral 4, it is to be noted that in accordance with Figure 1 the present device has eight of such housings all of the same construction and which for convenience in the further description of the procedures involved will be referred to as being disposed in the various positions of the conditioning cycle A, B, C, D, E, F, G, and H.

As shown in Figure 1, the housing structure A is disposed opposite the filling station at which point one of the barrels may be introduced therein by an operator standing in front of the machine. By introduction of a tool into the opening I2, the conveyor 2 may be rotated by successive steps to position successive housing structures in position at the filling station. Furthermore, in accordance with the procedures herein described in connection with the conditioning of the barrels l8, housing structures B and C are positioned to have a caustic solution directed onto the interior and exterior surfaces of the barrels disposed therein. The housing structure D is representative of the position which each successive housing structure takes for the draining of the caustic solution from the housing after the barrels have been treated thereby. Housing structure E is representative of the position which the housing structures assume during the introduction of a rinsing solution, such as water, after which such water is allowed to drain from the housings when in the position represented by the housing structure F. Housing structures G and H are representative of the positions which each successive housing structure takes during the cycle of operation when warm air alone is introduced into the housing structures for drying the barrels.

Since each of the housing structures 4 is of similar construction, as more particularly shown in Figure 3 of the drawings, reference will :be

- right position,

made to one only as to its detailed construction for the purposes of this illustration. The housing structure 4 is of general elongated formation comprising side walls 24 and 26 interconnected by the circular end wall 28 and defining a chamber 30 of the proper size to receive the barrel II to be conditioned. The front of the housing structure is provided with a slide frame 32 adapted to receive a closure member 34 which is raised and lowered through the handles 86 whereby, the barrel I8 may be introduced into and removed from the chamber 36.

The receiver I4 is connected to the upper inner margins of the housing structures and is formed with oppositely disposed baffles 26 for directing fluid through a discharge pipe 42 into the upper region of the chamber 36. The chamber 30 immediately below the discharge pipe 42 is partitioned by the baille 44, apertured as at 46, to permit the fluid to flow by gravity onto the upper end surface of the barrel and about its side wall surfaces. In order to properly control the dispersion of the fluid, baflle member 46 defines the marginal edge of the opening 46 adjacent the discharge 42. In order to control the upward dispersion of the fluid introduced into chamber 30, baflle plate 56 is provided to provide a tortuous passage of the air through the opening 46 to the atmosphere through the opening 54 in the top or end wall of the housing. Depending flange or baflle 52 is also provided at one side of opening 54.

The receiver I4 is further provided with a discharge conduit 56 extending downwardly on the inside of the housing structure and which has the horizontal extension 58 terminating in the vertical fitting 60 disposed within an outer fitting 62 attached to the air distributing conduit 64, one end of which leads into the housing structure from the rotatable distributor head 66 of the air supply system.

The fitting 62 extends upwardly beyond a support 68 for the barrel l8 and when the barrel II is introduced into the housing structure. the bung-opening 20 is inserted over fitting 62 so that conditioning fluid is introduced into the barrel from receiver 14 by gravity flow to the fitting 66, at which time the same is acted upon by air under pressure flowing through fitting 62 to disperse the same for effectively covering the entire interior surface of the barrel being treated.

The support 68 is characterized as including a pivotal support, as at 10, in the side walls 24 and 26 of the housing structure and the float members 12 and 14 which, under the action of fluid in the conditioning operation, cause the support to be moved from its dotted line position to that shown in full line position in Figure 3 of the drawings. Accordingly, it will be apparent that at the filling station A the support is disposed in such a position as to facilitate introduction of the barrel l8 into the housing structure. When the barrels are treated at stations B, C and E, the support is moved about its pivot point 10 to move the barrel into a substantially upthus facilitating the dispersion of fluid to all parts of the exterior surface. At the remaining stations during the cycle of operation, the tilting of the support as shown in Figure 3 of the drawings provides a convenient way of completely draining the conditioning fluid from the barrels through the bung-opening 20.

In order to facilitate the proper treatment of the end of the barrel adjacent the support 66, the

distributor conduit 58 is provided with a plurality of jets I8 adapted to project conditioning fluid to the end wall of the barrel undergoing treatment.

The lower end of each of the housing structures is provided with a chamber 'Il adapted to collect the conditioning fluid Ior raising the float members I2 and 14, the conditioning fluid being discharged through the discharge I8 into the annular shaped collector 88 which returns the conditioning fluid to the tanks or reservoirs holding the same, as through the discharge 82 shown in Figure 3 of the drawings.

As previously described, the conditioning fluids used in accordance with the present disclosure consist of caustic solution and rinsing water and, accordingly, the reservoirs or tanks for such material are shown at 84 and 85, respectively, both of which are of substantially the same construction and are disposed in substantially opposed relation below the track or support 8 for movement of the conveyor. Each of the tanks is provided with a plurality of baflles, such as 88,

adapted to provide a circuitous path for the fluid being used. Disposed within the tanks are a plurality of heater tubes 90 at the end of each set of which is provided a burner 92 for raising the temperature of the conditioning fluid. Each of these heater tubes extends through the end walls 54 of the tanks and is adapted to discharge the products of combustion into a central flue 96 defined at its top by the cylindrical wall 98 for discharging such products of combustion directly beneath the distributor head 66 of the air supply system. Distributor head 66 is provided with depending structure, generally represented as I00, embracing the cylindrical wall 98 of the flue and which is further provided with a plurality of lateral openings I82 adapted to permit the escape of these spent gases upwardly through the central portion of the device.

In circulating the caustic solution through the system, use is made of a centrifugal pump I84 operated by the motor I85, the pump having an intake I86 into the tank 84 and a discharge conduit I 08 extending up and over the conveyor and being provided with discharge nozzles I I8 and I I2 disposed to simultaneously introduce caustic solution into the space between adjacent partitions IE of the receiver I4 when the housing structures are moved into positions B and C.

In order to prevent loss of caustic solution and its dispersion onto parts of the equipment which might be damaged, a plate 4 is secured to the discharge nozzles 8- and H2 over that portion of the receiver into which caustic solution is being discharged.

The rinse water is similarly introduced into the receiver I4 when the barrels are moved into the position E through the medium of a centrifugal pump H6 operated by the motor ill, the pump having an intake 1 I8 into the tank 86 and having a discharge conduit I28 extending up and over the conveyor and discharging into the receiver l4 through the discharge fitting I22.

The air supply is constituted by a blower I24 operated through the medium of a motor I25 and which blower I24 delivers air through the conduit I28 extending up and over the conveyor and which is connected to a centrally disposed conduit I30 connected to the distributor head 56 through the slip joint I32 whereby the distributor head 68 can rotate in accordance with the movement of the conveyor.

In order to assure complete removal of conditioning fluid from the upper end of the barrels II, a suction device is provided for each of the housing structures consisting of a flexible tubing I34 having a hooked conduit I36 adapted to fit over the chime of the barrel to remove any residual conditioning fluid disposed therein. This flexible tubing I34 is connected with a fitting I38 extending through the wall 24 of the housing structure which is connected to conduit I40 leading to and being connected with a conduit I42 which has its inner end terminating within a conduit I44 constituting a supplemental. or auxiliary discharge for conditioning fluid from the next adjacent housing structure whereby discharge of fluid therefrom creates a vacuum through the vacuum system above recited for drawing water from the chime end of the barrel.

During the operation of the conditioning apparatus as above described, it is to be noted that the circulatory systems for the caustic solution and rinsing water are continuously in operation to provide the necessary conditioning fluid for the procem involved, which said conditioning fluids in both instances are supplied to the barrels by gravity flow. The air system is likewise continuously operated and is efiective through the fittings 62 in dispersing the conditioning fluids at the stations B, C and E and in facilitating the draining and drying of the barrels when in the remaining positions as shown in the drawings.

In order to assure the dislodgement of material adhering to the barrels during the conditioning operation, a. cam I46 is provided on the shaft 18 in association with each of the supports 68 and which cam through the medium of a motor I48 secured by bracket I58 to the exterior of the housing is adapted to rotate and intermittently engage the lower-most end of the barrel for the purposes described.

The container conditioning device above described is characterized by the simplicity of its construction, ease of manipulation, and particularly by the fact that conditioning of the containers is eifectually secured without the incorporation of high pressure fluid mechanisms which present dilficult maintenance problems with attendant high cost of operation.
