Definitions

  • the present invention relates to a flushing device for internal flushing of tanks, preferably ship's tanks, wherein at least one pipe for flushing liquid is rotatably mounted in the tank.
  • the flushing-liquid pipe has at least one flushing nozzle which is pivotally mounted relative to the flushing-liquid pipe.
  • a supply conduit is provided to feed flushing liquid to the flushing-liquid pipe and through said pipe to the flushing nozzle, which is adapted to direct jets of flushing liquid towards the inner sides of the tank.
  • the supply conduit comprises a through-flow member, in which a through-flow passage is provided for flowing through of flushing liquid.
  • a turbine wheel is rotatably mounted in said through-flow passage such that said tur- bine wheel is brought to rotate by means of flushing liquid flowing through the through-flow passage.
  • At least one by-pass device is provided to feed flushing liquid past the through-flow passage such that only a portion of the flow of flushing liquid flows therethrough.
  • the turbine wheel is provided to operate a driving device located outside the supply conduit, said driving device being provided to bring the flushing-liquid pipe to rotate and simultaneously the flushing nozzle to pivot.
  • Flushing devices for flushing ship's tanks are al- ready known from EP 0 723 909. It is also known to provide flushing devices with by-pass devices to see to that a part of the flushing water flows past the through-flow passage in which the turbine wheel is located. The purpose of these by-pass devices is to reduce the flow of flushing liquid through the through-flow passage and thus, the rotation of the turbine wheel.
  • Prior art by-pass devices are however complex, ineffective and voluminous, which means that the costs for manufacturing the flushing device are high. Furthermore, they do not permit setting of the rotary speed of the flushing-liquid pipe within a sufficient wide setting range when the flow of flushing liquid through the flushing device lies within a wide flow range. It is therefore necessary to supply several various flushing devices in order to cover a wide flow range, which for many reasons is disadvantageous.
  • the object of the present invention is to provide a flushing device at which said drawbacks are eliminated and this is arrived at according to the invention by providing the flushing device with the characterizing features of subsequent claim 1.
  • said device will have a functional and cost efficient by-pass device which also permits use of the flushing device within a substantially wider flow range for the flushing-liquid flow.

  • FIG. 1 schematically illustrates a flushing device 1 for internal flushing of tanks 2, preferably ship's tanks, with a suitable flushing liquid S.

  • the driving device 17 may e.g. be designed as defined in EP 0 723 909 and thus comprise a gear box 18 for reducing the speed of the rotary movement coming from the turbine wheel 14.
  • the reduced rotary movement is transmitted from the gear box 18 to a rotary gear mechanism 19, 20 which rotates a vertically directed pipe 21.
  • This pipe 21 cooperates in turn with the flushing-liquid pipe 9 for rotation thereof in the direction of rotation Rl .
  • the rotary movement from the gear box 18 is also transmitted to a gear mechanism in which a rotating member 22 transmits its rotary movement to a linearly up- and downwards moving member 23.
  • This member 23 cooperates with a vertically directed and linearly up- and downwards moving rod 24, which extends downwards through the pipe 21 and the flushing-liquid pipe 9 and cooperates through a gear 25 with the flushing nozzle 10 for pivoting said nozzle about the horizontal axis in the direction of rotation R2.

  • the outer side of the pipe member 12, the sides of the flanges 35 and the inner side of the through-flow member 11 together define the by-pass passage 34 (in this embodiment divided into four members) through which the portion F2 of the flow F of flushing liquid can flow.
  • the flanges 35 and thereby, the pipe member 12 can preferably be released from the through-flow member 11 for demounting the pipe member 12 therefrom and they can be as long or substantially as long as the pipe member 12.
  • the by-pass passage 34 may e.g. be designed such that it permits the portion F2 of the flow F of flushing liquid flowing therethrough to be larger than the portion Fl of the flow F of flushing liquid flowing through the through-flow passage 13.

  • FIGS 9 and 10 there is shown an embodiment with the same cylindrical pipe member 12 as in figures 7 and 8, but with the flow control device 36 located upstream of the pipe member 12.
  • the flushing device described above permits relative to prior art flushing devices, the following should be mentioned while referring to the diagrams of figures 11 and 12.
  • a prior art flushing device may e.g. be built for a flushing-liquid pressure of 8 bar (the pressure is gene- rated in a manner known per se by means of a pump device) and a flow volume of flushing liquid of about 30 m 3 /h.
  • the rotary speed of the flushing-liquid pipe 9 may in this embodiment be set within the setting range 0,5 - 1,5 rpm, which is a common range or interval for the rotary speed of flushing-liquid pipes.
  • the setting range is so narrow that the rotary speed of the flushing-liquid pipe can no longer be set within the common range or interval of about 0,5 - 1,5 rpm. This is illustrated in the diagram of figure 11 by the taper of the setting range from 15 m 3 /h and by the very narrow setting range at 30 ⁇ vVh.

  • the pipe member 12 may eventually be dispensed with and the through-flow pipe 13 defined by the through-flow member 11 or by any other member.
  • the by-pass device 33 may have a suitable number of by-pass passages 34 of suitable size and the flow control device 36 may be designed otherwise than described above.
