Definitions
- the present invention relates to a method to be used in containers or similar equipment and especially a method for transport/storage containers.
- the problem behind the invention is to eliminate at an optimum tank cleaning after a certain tank has been used for transport/storage of a specific product which is not allowed to contaminate another product to be used later on in the tank.
- the known system requires a premade special flexible inner container having a filling opening in a predetermined position. This is not acceptable as tanks/containers of the actual type have very varying construction and have dome covers in completely different positions from tank type to tank type. Neither does the known system provide filling/emptying facilities that are compatible with existing auxiliary systems.
- the object of the invention is to eliminate the shortcomings and offer a more advantageous and user oriented alternative than the known ones and one which normally does not require alteration of existing equipment for loading and unloading, respectively.
- the invention provides a method for the transport/handling of goods of liquid type or powder type or similar that is pourable into and out from, respectively, a container/ tank.
- the method comprises the steps of inserting, by assistance of pressurized air, a tube shaped, end sealed flexible inner container, having an excess of volume relative the tank and an expanded form corresponding to the shape of the tank, into the tank through an arbitrarily placed opening in the tank, for instance a dome cover, attaching a pipe connection piece to the inner container, forming a hole in the inner container at the region of the connection piece, and supplying/removing said goods to/from the container through said connection piece and hole.
- the connection piece is attached first onto the inner container and the hole is formed thereafter.
- a hole may be formed first and the connection piece attached thereafter.
- connection piece is attached adhesively to the inner container via a flange.
- connection piece and the flange for instance are injection moulded of plastics and formed as an integral unit.
- FIG. 1 schematically shows a tank having a flexible inner container and connection/venting pieces
- Figure 2 shows in an end view the flexible inner container in an expanded state relative the inner cross section of the tank
- Figure 3 shows the elements of the pipe arrangement of the filling/pouring connection piece
- Figure 4 shows the elements of the venting connection piece. Description of a preferred embodiment
- the reference numeral 10 in Figure 1 indicates a tank, for instance a transport tank on a vehicle, having a dome cover 11 for allowing access to the interior of the tank.
- a flexible inner container 12 for instance of polyethylene, preferably of a thickness within the range 0,1 to 0,5 mm, is insertable and has a maximum expanded size at least corresponding to the volume of the tank 10.
- the tank 10 may of course also represent a tank section of a tank having several such sections, meaning that the term tank in the specification as well as in the claim does include also this possibility.
- Figure 2 By broken lines in Figure 2 there has been shown the cross section of the tank relative the maximum cross section of the flexible container.
- Figure 2 cannot occur in practice as the rigid wall of the tank prevents expansion in excess of the limit defined by the tank volume.
- An excess of "volume" of the inner container is of course suitable, i.a. from a strength point of view.
- the inner container is seamless in the longitudinal direction thereof, meaning that it is manufactured from an extrusion blown film of a suitable diameter and sealed at both ends thereof.
- connection piece comprising an attachment plate 13 and a pipe 14 forming a filling pipe and a puring pipe.
- a corresponding arrangement 13', 14' forms a venting pipe.
- connection pieces which may be injection moulded of plastics as an integral unit or as separate weldable parts, may be accomplished by welding to the inner container, but preferably is obtained by a double adhesive tape disc 15, 15'. As shown by the arrows 16, 16' the disc is fixed adhesively onto the flange 13, 13'. The protective film on the other side of the tape is to be removed when the connection piece (pieces) are applied onto the inner container 10.
- the inner container is pushed down in the tank 10 through the dome cover, such that the container well covers the interior of the tank.
- This insertion possibly may be supported by pressurized air.
- the air orfice is inserted through the inner container at a region approximately corresponding to the position of the actual dome cover.
- the concection piece 14 (possibly both connection pieces 14, 14') is attached to the inner container at the region of the dome cover (or possibly dome covers) by insertion through said cover. Thereafter the wall of the container 10 is penetrated by using scissors or knife.
- connection pieces have been described in connection with a specific embodiment of connection pieces, tank and inner container, it is realized that the inventive idea as defined in the corresponding claims is applicable also in other environments.
Abstract
Procédé pour supprimer le nettoyage du réservoir lors du transport de marchandises liquides, de marchandises pulvérulentes ou similaires, qui peut être versé dans un réservoir, respectivement en être retiré. Un récipient intérieur flexible (12) en forme de tube et scellé à l'extrémité, d'un volume supérieur au volume du réservoir et dont la forme gonflée correspond à la forme du réservoir (10), est inséré à l'aide d'air comprimé dans le réservoir par un couvercle bombé placé au hasard (11). Une pièce de raccord de tuyau est fixée au récipient intérieur et un trou est formé dans la zone de la pièce de raccord de tuyau; les marchandises sont ensuite amenées dans le réservoir par lesdits trou et pièce de raccord de tuyau.Method for eliminating the cleaning of the tank during the transport of liquid goods, pulverulent goods or the like, which can be poured into a tank, respectively withdrawn therefrom. A flexible inner container (12) in the form of a tube and sealed at the end, of a volume greater than the volume of the tank and whose inflated shape corresponds to the shape of the tank (10), is inserted using compressed air in the tank by a randomly placed domed cover (11). A pipe fitting piece is attached to the inner container and a hole is formed in the area of the pipe fitting piece; the goods are then brought into the tank through said hole and pipe connection piece.
