Definitions

  • the present invention relates to a method of pickling and/or passivating at least an inside of a container.
  • the invention further relates to a manipulator of or for such a method of pickling and/or passivating at least an inside of a container.
  • Tanks or (pressure) vessels are applied in many varieties and applications, and may comprise storage tanks for containing, storing or preparing a fluid, such as in an industrial process. They may also comprise a pressure vessel in a system, such as a vessel of a boiler or other (domestic) heating or hot water system. In this application, the general wording container is used to comprise both tanks and (pressure) vessels.
  • Such a coating may protect an inner side of said container against an aggressive fluid, or otherwise make said container less susceptible to degradation and possibly failure.
  • a protective coating against corrosion may be applied using passivation.
  • Passivation in physical chemistry and engineering, refers to a material becoming "passive," that is, less affected or corroded by the environment of future use. Passivation involves creation of an outer layer of shield material that is applied as a micro coating, created by chemical reaction with the base material, or allowed to build from spontaneous oxidation in the air.
  • passivation is the use of a light coat of a protective material, such as metal oxide, to create a shell against corrosion.
  • Passivation media are of an aggressive nature, and contact to the human skin is to be prevented at all times.
  • the container Prior to passivation, the container may be exposed to a pickling operation for thoroughly cleaning the container in anticipation of the passivation process.
  • one or more than one conduit inside a container may be bend in a complex three dimensional shape to define a coil of a heat exchanger. In case of multiple conduits, they may be interwoven.
  • These complex interiors impose challenges to provide a protective coating substantially covering the complete interior surface of a container, i.e. also providing protection in all corners and irregular spots.
  • the lifetime of a container will be determined by the weakest spot, it is desirable to obtain a reliable and substantially full coverage of pickling and/or passivation inside the interior of also the most complex containers. It is especially for such complex containers, for which manufacturing is laborious and costly, that a reliable and prolonged lifetime is highly desired.
  • US 2,726,201 A1 is considered the closest prior art, relative to which at least the characterizing features of claim 1 are novel. It discloses a method for anodic pickling and nickel plating of an interior of a tank using a single electrolyte.
  • the tank may be a container such as are used in chemical process industries and in railway and truck tank cars.
  • the tank car container is provided with supporting hydraulic jacks at each end of the tank container. While a pickling operation is performed, it may "rock" the tank car container by alternately actuating the hydraulic jacks, and a valve connected to an opening in the bottom of the tank container bay be opened to allow a circulation of the electrolyte through a filter and an electrolyte cell.
  • An objective of the present invention is to provide a method of pickling and/or passivating at least an inside of a container that is improved relative to the prior art and wherein at least one of the above stated problems is obviated or alleviated.
  • the method is capable of distributing the pickling and/or passivation liquid inside said container and to thereby provide a substantially full coverage of pickling and/or passivation inside the interior of even the most complex types of containers.
  • the trajectory is a pre-determined trajectory, it may be controlled and optimized, thereby providing a reliable end product having a consistent quality.
  • the method may be automated to a high level, thereby reducing the need for manual labour and associated health risks for said workers.
  • a substantially complete draining of pickling and/or passivation liquid out of said container further improves the end product and reduces health risks for any worker handling the container after pickling and/or passivation thereof.
  • the pre-determined trajectory may effectively prevent any pickling and/or passivation liquid residue to remain in said container after draining.
  • the step of manipulating the container in the pre-determined trajectory is preceded by the step of determining said trajectory in dependence of - the position of at least one opening in the one or more than one wall of said container.
  • the position of the at least one opening may selectively be positioned either at an uppermost position to allow any air to escape during submersion of said container, or a lowermost position for draining the pickling and/or passivation liquid out of said container.
  • the said at least one opening is at least selected for allowing a fluid to leave said container. This fluid may be air during submersion of the container in a bath comprising pickling and/or passivation liquid, or pickling and/or passivation liquid that is to be drained after pickling and/or passivation.
  • the at least one opening for venting air or draining pickling and/or passivation liquid may be the same opening, as well as different openings, arranged in a wall of the container.
  • the step of manipulating the container in the pre-determined trajectory is preceded by the step of determining said trajectory is furthermore also in dependence of an inner contour of said container being defined by an inner side of one or more than one wall and one or more than one internal conduit of said container.
  • the inner contour may cause entrapment of fluid.
  • This fluid may be air during submersion of the container in a bath comprising pickling and/or passivation liquid, or pickling and/or passivation liquid after pickling and/or passivation.
  • the pre-determined trajectory may be determined to follow a path that may guarantee on the one hand that substantially all air may be vented during filling of the container with pickling and/or passivation liquid, while it on the other hand may also guarantee that substantially all pickling and/or passivation liquid is forced to flow out of any potential entrapment positions and corners under the influence of gravity or movement of said container, before said pickling and/or passivation liquid is effectively drained. In this way it may be prevented that any pickling and/or passivation liquid residue is left in the container after the step of draining thereof.
  • the invention further relates to a manipulator of or for a method of pickling and/or passivating at least an inside of a container according to any of the foregoing claims, said manipulator comprising:
  • An exemplary container 1 shown in Figure 1 comprises a surrounding wall 2 and an internal conduit 3 arranged inside an inner space 4 of said container 1.
  • the internal conduit 3 in the shown embodiment is a spiral shaped internal conduit 3 that provides a relative large contact surface for heat transfer between a fluid to be transported through said conduit 3 and a fluid to be contained inside the inner space 4 of said container 1.
  • Such a container 1 is an example of a container 1 having a relatively complex inner contour 6 defined by an inner side 7 of the one or more than one wall 2 and the one or more than one internal conduit 3 of said container 1.
  • the skilled person will however understand that containers 1 having an inner contour of a complex shape may be provided in a great variety, each providing their own specific challenges during pickling and/or passivation.
  • the shown container 1 further comprises a plurality of openings 8 in the wall 2 thereof.
  • the step of manipulating the container 1 in the pre-determined trajectory T may be preceded by the step of determining said trajectory T in dependence of the inner contour 6 of said container 1 being defined by the inner side 7 of one or more than one wall 2 and the one of more than one internal conduit 3 of said container 1.
  • the step of determining said trajectory T in dependence of the inner contour 6 of said container 1 may comprise determining said trajectory T for collecting the pickling and/or passivation liquid 10 out of potential collection spots defined by said inner contour 6.
  • the step of manipulating the container 1 in the pre-determined trajectory T may be preceded by the step of determining said trajectory in dependence of the position of at least one opening 8 in the one or more than one wall 2 of said container 1, wherein said at least one opening is selected for allowing a fluid to leave said container 1.
  • Said fluid may be air 12 or pickling and/or passivation liquid 10. More in particular, said at least one opening 8 may be selected for the steps of venting air 12 out of the container 1 during filling thereof with a pickling and/or passivation liquid 10 ( Figure 3 ), and/or draining the pickling and/or passivation liquid 10out of said container 1 ( Figure 5 ). By draining substantially all pickling and/or passivation liquid 10, it may be prevented that any pickling and/or passivation liquid residue is left in the container 1 after draining.
  • the step of manipulating the container 1 in the pre-determined trajectory T is preceded by the step of determining said trajectory in dependence of both the inner contour 6 of said container 1 and the position of at least one opening 8 in the one or more than one wall 2 of said container 1.
  • the step of determining said trajectory T in dependence of the position of the at least one opening 8 selected for allowing the fluid to leave said container 1 comprises determining said trajectory T for temporarily orienting and holding said container 1 with said opening 8, 8-d selected for draining the pickling and/or passivation liquid at a lowermost position of said container 1 ( Figure 5 ).
  • pickling and/or passivation liquid 10 may be arranged inside said container using (not shown) nozzles entering said container 1 via at least one of the openings 8 and spraying said pickling and/or passivation liquid 10 inside said container 1, the invention proposes the step of at least partly submerging said container 1 in a bath 13 containing said pickling and/or passivation liquid 10.
  • the method comprises the step of fully submerging said container 1 in said bath 13. It is remarked that the method according to the invention is related to pickling and/or passivating at least an inside of the container 1, because said inside causes the most problems.
  • the outside of said container 1 may be passivated, especially and automatically when the container 1 is fully submersed in the pickling and/or passivation liquid 10.
  • the internal conduit 3 would have a complex three-dimensional shape and pickling and/or passivation liquid 10 would enter said internal conduit 3, it may be difficult to fully drain said internal conduit 3.
  • the ends of the internal conduit 3 may be temporarily closed of.
  • the step of determining said trajectory T in dependence of the inner contour 6 of said container 1 comprises determining said trajectory T for guiding any air 12 that may be trapped by said inner contour 6 to an uppermost position in the container 1 ( Figure 3 ).
  • determining said trajectory T may be done in dependence of the position of the at least one opening 8 in the one or more than one wall 2 of said container 1, and comprises determining said trajectory T for temporarily orienting and holding said container 1 with said opening 8, 8-v at an uppermost position of said container 1 to allow any air 12 to escape, i.e. vent, out of said container 1.
  • a pickling and/or passivation system is shown in the top view of Figure 7 , in relation to two alternative side views in Figures 8 and 9 showing carriages 14 of a first type 15 and of a second type 16, respectively.
  • the step of holding the container 1 by the manipulator 9 may thus comprise the step of supporting said container 1 by a carriage 14 that is moveable along a guide 17.
  • the step of arranging the pickling and/or passivation liquid 10 inside the container 1 may comprise the step of guiding said container 1 in and out of the bath 13 by moving said carriage 14 along the guide 17.
  • the movement may be in a single direction as shown in Figures 8 and 9 , or a movement back and forth, as will be described in more detail for the third embodiment shown in Figure 10 .
  • Manipulating of said container 1 may comprise the step of manipulating the container 1 along the pre-determined trajectory T having a three-dimensional shape. By moving the container 1 along a three-dimensional trajectory T in space, any fluid may be effectively transferred to an associated opening 8, 8-d, 8-v.
  • Manipulating the container 1 along the pre-determined trajectory T may be performed with an articulated arm 18 of said manipulator 9.
  • the manipulator 9 may thus comprise an articulated arm 18 and/or a guide 17 and at least one carriage 14, and a controller 19 (only shown in Figure 2 ) configured to manipulate the container 1 along the pre-determined trajectory T to thereby distribute the pickling and/or passivation liquid 10 inside said container 1, and successively drain the pickling and/or passivation liquid 10 out of said container 1.
  • the manipulator 9 may only comprise an articulated arm 18, effectively forming a standalone robot that is configured to manipulate the container 1 along the predetermined trajectory T.
  • the manipulator 9 comprises both the guide 17 and at least one carriage 14 and the articulated arm 18, wherein the at least one carriage 14 comprises the articulated arm 18.
  • a high level of flexibility to move said container 1 along the pre-determined three-dimensional trajectory T is obtained.
  • Figure 9 differs from the embodiment shown in Figure 8 in that the articulated arm 18 is replaced by a length adjustable arm 20 that may extend to lower the carriage 14 relative to the guide 17 and thereby submerge the container 1 in the bath 13 of pickling and/or passivation liquid 10.
  • the guide 17 itself may approach the bath 13 (not shown).
  • the top view of the third embodiment shown in Figure 10 discloses a pickling and/or passivation system using a plurality of baths 13 with pickling and/or passivation liquid 10. Applying a plurality of baths 13 results in an increased flexibility. After all, containers 1 may ideally be exposed to submersion in said pickling and/or passivation liquid 10 for different time intervals. For example, a single big container 1 or two smaller containers 1 carried on either side of one carriage 14 may require a longer exposure to the pickling and/or passivation liquid 10 than a single container 1 of a smaller size. Using multiple baths 13, each container 1 may be exposed for an optimal exposure time, without delaying other containers 1 as would be the case in a single throughflow bath 13 as shown in Figure 7 .
  • each of the baths 13 may be temporarily taken out of business for maintenance work, such a cleaning of said respective bath 13, while not having any negative effect on production capability in the other baths 3 that are not being serviced at that time. It is also conceivable that some baths 13 contain pickling liquid, while other baths 13 contain passivation liquid.
  • Figure 10 also shows that one carriage 14 may carry multiple containers 1, which are preferably arranged on opposite sides to maintain a balance.
  • a compensator 21 see upper and lower right baths 13 in Figure 10 .
  • the compensator 21 may simply comprise a weight 22 (shown in upper right bath 13 in Figure 10 ), but it preferably comprises a weight 22 arranged on an arm 23 that may be extended sideward relative to the carriage to provide a moment arm (shown in lower right bath 13 in Figure 10 ).
  • This extension of said arm may be controlled by said controller 19, so that an automated balancing is obtained and it is prevented that a human worker needs to manually add or remove a weight of the compensator 21.
  • pickling and passivation have been consequently mentioned in an and/or construction to define that the invention may either concern pickling or passivation, or a combination of both pickling and passivation.
  • the process is identical, but the respective liquid differs and is a pickling and a passivation liquid, respectively. If pickling and passivation are applied both, this may either be obtained by the container 1 to be e.g. first submerged in a bath 13 containing pickling liquid, and successively in a bath 13 containing passivation liquid. It is however also conceivable that a bath 13 may comprise a mixture of a pickling liquid and a passivation liquid, allowing the pickling and passivation of the container 1 to be applied in one go.
