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 turbine 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 according to the preamble of claim 1 are already known from EP 0 723 909 and WO 95/22415 . 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 flushing device 1 includes a supply conduit 3 which is connected to a vertically directed pipe 4.
  • This pipe 4 is located above the upper side 5 of the tank 2 and includes a mounting plate.6 through which it is mounted on said upper side 5.
  • the pipe 4 has a bearing member 7 in which upper parts 8 of a vertically directed flushing-liquid pipe 9 are rotatably journalled about a vertical geometric axis.
  • the flushing--liquid pipe 9 extends a suitable distance down into the tank 2 and it includes at least one flushing nozzle 10 which is mounted in the tank 2 such that it can direct jets SS of flushing liquid towards the inner sides, top and bottom of the tank 2.
  • the flushing liquid S is fed from the supply conduit 3, the pipe 4 and the flushing--liquid pipe 9 to the flushing nozzle 10.
  • a through-flow member 11 of the supply conduit 3 includes a pipe member 12 defining a through-flow passage 13 for flushing liquid S and in this through-flow passage 13 there is mounted a turbine wheel 14 which is provided to be rotated by the flow F of flushing liquid through the through-flow passage 13.
  • the rotary movement of the turbine wheel 14 is transmitted out of the supply conduit 3, preferably be means of a magnetic coupling 16, through a closed and eventually openable portion 15 of the wall of the supply conduit 3.
  • the magnetic coupling 16 may e.g. be designed as described and illustrated in EP 0 723 909 .
  • 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 R1.
  • 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 turbine wheel 14 consists of a hub 26 with a number of outwardly directed turbine blades 27 which are located in the through-flow passage 13 such that the turbine wheel 14 is rotated by the flow of flushing liquid therethrough.
  • the turbine wheel 14 can preferably be set in the longitudinal direction of the through-flow passage 13 such that its rotary speed increases with the distance said turbine wheel 14 is moved into said through--flow passage 13.
  • This controllability or adjustment is arrived at by means of a suitable setting device which may include a pin 28 with outer or external threads, through which it is screwed into a threaded hole 29 in the through-flow member 11 beneath the through-flow passage 13.
  • Lower parts of the hub 26 of the turbine wheel 14 cooperate with the pin 28 through a spherical bearing 30, which permits rotation of the turbine wheel 14 relative to said pin 28.
  • Upper parts of the hub 26 of the turbine wheel 14 intervene displaceably in a sleeve 31 with an inner screw spring 32 and the hub 26 transmits or transfers its rotary movement to the sleeve 31.
  • the sleeve 31 cooperates with an inner member 16a of the magnetic coupling 16 located within the closed portion 15 of the supply conduit 3 and said inner member 16a cooperates with an outer member 16b of the magnetic coupling 16.
  • the turbine wheel 14 can be moved or displaced between a lower and an upper position relative to the pipe member 12 and can be set in these and other positions therebetween such that the distance between those parts of the turbine wheel 14 defining the through-flow passage 13 and the pipe member 12 can be varied. The closer to the pipe member 12 the turbine wheel 14 is located, the faster is the turbine wheel 14 rotated by a flow F1 of flushing liquid through the through-flow passage 13 and vice versa.
  • the turbine wheel 14 is set in a lower position in which it is entirely or to the greater part located in the through-flow passage 13.
  • the pin 28 is screwed into the through-flow member 11 until the desired position of the turbine wheel 14 has been reached relative to the through-flow passage 13.
  • the hub 26 and turbine blades 27 of the turbine wheel 14 taper, preferably conically, in the direction of flow of the flow F1 of flushing liquid through the through-flow passage 13.
  • the pipe member 12 or at least the inner side thereof has a corresponding tapering shape, preferably conically tapering shape in said direction of flow.
  • the flushing device 1 includes a by-pass device 33 for feeding flushing liquid S past the through-flow passage 13, such that only a portion F1 of the flow F of flushing liquid flows through the through-flow passage 13, while the remaining portion F2 of the flow F of flushing liquid flows through the by-pass device 33.
  • the by-pass device 33 includes at least one by-pass passage 34 which is provided in the same through-flow member 11 as the turbine wheel 14, i.e. inside the through--flow member 11 forming part of the supply conduit 3 and in which the pipe member 12 is found.
  • the by-pass device 33 becomes functional and cost efficient inter alia because it is built into a part of the supply conduit 3 close to the turbine wheel 14.
  • the pipe member 12 and the through-flow member 11 define the by-pass device 33.
  • the outer diameter of the pipe member 12 is e.g. less or smaller than the diameter of the parts of the through-flow member 11 surrounding the pipe member 12 and the pipe member 12 has a number of, e.g. four, outwardly directed flanges 35, which can be uniformly distributed around the pipe member 12.
  • the flanges 35 are dimensioned such that they with outer edges engage the inner side of the through-flow member 11 and they are adapted for locating the pipe member 12 relative to the through-flow member 11 such that the by-pass passage 34 is defined therebetween.
  • 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 F1 of the flow F of flushing liquid flowing through the through-flow passage 13.
  • a flow controlling or regulating device 36 can be provided on the turbine wheel 14 or on members connected thereto. This flow control device 36 is adapted to define a through-flow gap 37 with the pipe member 12 for flushing liquid S.
  • the flow control device 36 is displaceable relative to the pipe member 12 by moving or displacing the turbine wheel 14 in an axial direction relative to the pipe member 12 for varying the size of the through-flow gap 37 and thereby, the volume of flow of flushing liquid through the through-flow gap 37.
  • the flow control device 36 is preferably provided downstream of the pipe member 12 such that it defines the through-flow gap 37 with a lower edge of the pipe member 12 and such that the through-flow gap 37 is larger when the turbine wheel 14 is set close to the pipe member 12 - as is shown in figure 1 - than if the turbine wheel 14 is set farther away from the pipe member 12 - as is shown in figure 2 .
  • the flow control device 36 is situated at a certain distance from the pipe member 12 - e.g. also in a lower position - while when the turbine wheel 14 is set farther away from the pipe member 12 - e.g.
  • the flow control device 36 is situated at a less or smaller distance from the pipe member 12 - e.g. also in a position above the lower position - in order to throttle the flow F1 of flushing liquid in the through--flow passage 13.
  • the flow control device 36 can be provided transverse relative to the direction of flow of the flushing--liquid flow F1 through the through-flow passage 13 and it can have an outer diameter which corresponds or substantially corresponds with the diameter of the closest parts of the through-flow passage 13.
  • the flow control device 36 can be designed as a circular or substantially circular washer 38.
  • the washer 38 is preferably provided transverse relative to the direction of flow of the flow F1 of flushing liquid through the through-flow passage 13 and it preferably has an outer diameter which substantially corresponds with the diameter of the nearest parts of the through-flow passage 13.
  • the flow control device 36 may instead be located upstream of the pipe member 12.
  • the pipe member 12 may be cylindrical instead of conical and the flow control device 36 can be located downstream of the pipe member 12.
  • figures 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.
  • a prior art flushing device may e.g. be built for a flushing-liquid pressure of 8 bar (the pressure is generated 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 m 3 /h.
  • the by-pass passage 34 permits bringing a portion F2 of the flow F of flushing liquid to flow through the by-pass passage 34 such that the setting range for setting the rotary speed of the flushing-liquid pipe 9 - as is shown in the diagram of figure 12 - can be varied within the common range or interval of about 0,5 - 1,5 rpm at a flow volume of the flushing liquid S of up to 45 m 3 /h.
  • Said flushing device 1 with a by-pass device 33 may thus be used for setting the common range or interval of about 0,5 - 1,5 rpm for the rotary speed of the flushing-liquid pipe 9 within a much larger range or interval for the flow volume of the flushing liquid than what previously has been possible with prior art flushing devices.
  • the flushing device 1 described above By equipping the flushing device 1 described above with a by-pass device 33 as well as a flow control device 36, it is e.g. possible to reduce the rotary speed of the turbine wheel 14 substantially more than if the flushing device 1 comprises only a by-pass device 33. If e.g. the turbine wheel 14 is raised from a lower position - as is shown in figure 2 - to an upper position - as in figure 3 - the washer 38 will automatically be displaced or moved closer to the pipe member 12 such that the through-flow gap 37 gets substantially smaller or narrower, e.g. the flow F1 of flushing liquid through the through-flow passage 13 is throttled considerably, which means that the flow F2 of flushing liquid through the by-pass passage 34 increases correspondingly.
  • said by-pass device 33 together with the flow control device 36 permit setting of the rotary speed of the flushing-liquid pipe within the common interval of about 0,5 - 1,5 rpm, within a substantially larger range or interval for the flow of flushing liquid in m 3 /h, e.g. within the range from about 10 m 3 /h to at least about 55 m 3 /h.
  • 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.
  • the flushing device may also have more than one flushing nozzle 10 and its through-flow member 11 with associated members and driving device 17 with associated members can be located in the tank 2 instead of outside the tank.
