Definitions

  • the present invention relates to an apparatus for the semi-automatic sucking of oily bilge-waters and other waste liquids from small and medium watercrafts.
  • the present invention further relates to the sucking method used by said apparatus.
  • the oily waters discharged from the ships are collected and sent to conditioning centres wherein oils are regenerated so that they can be used again, whereas the water, without any oily substances, is discharged into the sea after being purified according to the law.
  • waters trading doesn't comprise only big ships, because there are also a lot of small or medium sized boats and other watercrafts, both touristic and commercial, such as fishing-boats, yachts, small ferry-boats, patrol motorboats etc., which have the same problem of the discharge of the bilge-waters even though in a smaller way.
  • the present means mentioned above is sized for the needs of big ships and therefore is not suitable to be used by medium and small watercrafts, because of the high costs involved.
  • a first problem is linked to the fact that said dockside system requires that a continuous vacuum is made in a storage vessel even when no sucking operations have to be performed.
  • the second problem is due to the need of a payment in advance by each user of the costs corresponding to the volume of the liquids to be sucked and treated.
  • the problem due to the costs is important when such sucking apparatuses have to be placed either in different points of touristic harbours or in small touristic harbours.
  • the apparatus comprising a flexible tube having an end which is suitable for being plunged into a liquid to be sucked, collecting means of said liquid communicating with said flexible tube, sucking means creating vacuum conditions in the collecting means.
  • said collecting means includes:
  • the sucking means creates the vacuum conditions only during the sucking phase.
  • a method for the semi-automatic sucking of oily bilge-waters and other waste liquids from small and medium watercrafts is characterised in that it includes the following phases:
  • an apparatus for sucking and storing liquids comprises a flexible tube 10 having an end 10a which is suitable for being plunged in a liquid to be sucked.
  • Tube 10 can be rolled up on winding means 3 and is in communication with an intermediate vessel 6 wherein vacuum conditions are created by sucking means such as a pump 9.
  • Intermediate vessel 6 is in communication with a storage vessel 8 through an exhaust electrovalve 7.
  • Intermediate vessel 6 comprises a sensor 15 to control the liquid level inside it.
  • Sucking pump 9 is in communication with intermediate vessel 6 through a circuit 16 comprising a safety valve 12 and a filter 13 protecting pump 9.
  • a processing unit 4 shown only in figure 3 is connected with a not shown electric power supply and acts as remote control of the apparatus shown in figure 1 and in particular controls valve 7 and pump 9.
  • Processing unit 4 is mounted on a support cover 1 of the apparatus and is also electrically connected with sensor 15 and push-button panel 11. In the latter case the connection being possible through electrical wires fixed along tube 10 and not shown.
  • a first opening is provided through which the access to a screen 5 and a keyboard 2 is possible with a not shown printer able to issue receipts through a slot 2a.
  • a second opening 1b allows access to flexible tube 10, shown in figure 1.
  • a machine for payment for example by credit cards, tokens, bank notes and so on is advantageously provided for, not described in details because already known to a person skilled in the art.
  • a user who needs to discharge the oily waters from the bilge of his watercraft must initially be able to take end 10a of flexible tube 10 and unroll it. This is possible only after having opened opening 1b after the input of the watercraft's data, after having chosen a discharging program by means of keyboard 2 and after having paid in advance the amount displayed on screen 5. For instance, the user can choose a program either for sucking a fixed amount of liquid or for sucking during a fixed period of time. The payment is referred to the maximum volume which can be sucked during a single sucking phase.
  • the sucking can be either stopped or re-started at any time by the user.
  • the sucking stops in one of the following cases:
  • sucking phase is considered ended by processing unit 4, which operates the opening of electrovalve 7 which is placed at the bottom of intermediate vessel 6 so that the discharging of the liquid sucked into storage vessel 8 is allowed.
  • the capacity of the latter is defined according to the size of the whole apparatus. For instance, the capacity of storage vessel 8 is comprised between 2000 and 3000 litres.
  • the user can select the rolling of tube 10 by one of keys 11a which powers engine 3a of tube winder 3 (figure 1). Afterwards, when opening 1b is shut, the user can get a document from slot 2b which certifies the discharge and points out the data put in at the moment of the choice of the sucking programme, comprising the data of the watercraft and of its owner. In the meanwhile, processing unit 4, has stored such data so that the legal customs controls can be done when emptying storage vessel 8.
  • the method which is at the basis of the apparatus according to the invention includes the phases of payment as above illustrated, of the sucking started by the payment and of storing at the end of the sucking.
  • the presence of an intermediate vessel 6 and of a separate storage vessel 8 allows for the payment in advance of the sucking operations referred to a fixed amount of liquid.
  • the storage vessel should not be brought under vacuum conditions, thus allowing to save on the size of the pump. This saving is even greater because pump 9 works only during the sucking phase.
  • vessel 8 can be extended above intermediate vessel 6.
  • a pump can be provided which pushes the liquid from vessel 6 to vessel 8 when the level L of the latter is higher than the level of electrovalve 7.
  • the apparatus and the corresponding method according to the present invention can also be used for emptying WC reservoirs provided on watercrafts.
  • An apparatus for discharging black liquor could then be placed near an apparatus for discharging oily waters.
