  • the nozzle is pivotable or rotatable about a second axis (e.g., horizontal) which at an angle to the first axis.
  • a single driving means (preferably a single turbine powered by wash liquid) is connected via gears and a clutch mechanism to rotate the housing about the first axis and via other gears to pivot or rotate the nozzle about the second axis, the ratio of the angular speeds of the nozzle and housing about their respective axes being constant, but the absolute angular speeds being varied in accordance with a selected program (e.g., as determined by the profile of a cam) so that distant tank walls are sprayed as effectively as proximate walls, during use.
  • a selected program e.g., as determined by the profile of a cam
  • TANK CLEANING MACHINE WITH SELECTIVE WASH PROGRAMMING This invention relates to machines for cleaning tanks.
  • Such machines however. have one serious defect and that is their inability to equalize the wash water over the whole tank surface. This occurs because the nozzle is suspended relatively close to the underside of the tank top, and it is normal for the nozzle to elevate a fixed amount about the horizontal axis for every turn about the vertical axis. If the nozzle housing is rotated at a constant rate the nozzle will take as long to travel from the vertically downward position to the horizontal position as it will do to travel from the horizontal position to the vertically upward position, thereby supplying as much wash water to the top metre or so of the tank as the whole of the rest of the tank.
  • the present invention provides a method ofcleaning a tank employing a tank cleaning machine of the type having a nozzle which is rotatable or pivotable about a first axis substantially perpendicular to the longitudinal axis of the nozzle. the nozzle being mounted in a housing which is rotatable about a second axis at an angle to the said first axis. the method comprising driving the nozzle and the housing about their respective axes from the same drive means with their angular velocities in a constant ratio. and varying their absolute angular velocities in a predetermined manner in accordance with a selected program.
  • the invention comprises a tank washing machine comprising a nozzle which is rotatable or pivotable about a first axis substantially perpendicular to the longitudinal axis of the nozzle and which is mounted on a housing which is rotatable about a second axis at an angle to the said first axis.
  • a common drive means connected for rotating the housing and rotating or pivoting the nozzle in such a manner that the angular velocity of the housing will be in a fixed ratio in relation to the angular velocity of the nozzle.
  • a selected program Preferably.
  • the selected program is provided by the interaction of a cam and a cam follower which are driven from the said drive means. and the relative movements of the cam and cam follower are employed to influence the power output from the drive means. e.g. by varying the relative angle between the blades of a drive turbine powdered by the wash liquid and the angle ofimpingement of the wash liquid on the blades.
  • a tank washing machine suitable for cleaning tanks of oil tankers comprises a wash liquid supply pipe in communication with a nozzle housing rotatable about its longitudinal axis. a nozzle fixed to the nozzle housing. said nozzle being rotatable about an axis at an angle to its own longitudinal axis and at an angle to the axis of rotation of the housing.
  • a turbine actuated by the flow of wash liquid. means whereby. whilst the turbine is rotating. the relative angle between the turbine blades and the flow of wash liquid impinging on the turbine blades may be varied (cg. by changing the altitudes of the blades. and/or by changing the direction of liquid flow onto the blades employing flow nozzles) and means whereby the speed of rotation of the turbine controls the speed of rotation of the nozzle housing and the speed of the rotation of the nozzle.
  • the wash liquid supply pipe is usually designed so that when the machine is installed in position for use. at least a large part of the pipe projects substantially vertically into the tank from the roof of the tank. Preferably it carries an annular plate for fixing to the hole in the roof of the tank. Part of the supply pipe may if desired be bent. e.g.. through 90. so that when the machine is fitted in position part ofthe supply pipe outside the tank is for example horizontal so that it can be connected easily to the source of wash liquid.
  • the nozzle housing communicates with the wash liquid supply pipe and usually it is co-axial with this pipe. and therefore usually rotates about a substantially vcrtical axis when the machine is in position in the tank.
  • the nozzle is rotatable about an axis at an angle to the axis of rotation of the housing. and usually this angle is a substantial angle. e.g.. 90.
  • this angle is a substantial angle. e.g.. 90.
  • the axis of rotation of the nozzle housing is substantially vertical when the machine is in position in the tank.
  • the axis of rotation of the nozzle is substantially horizontal.
  • the axis about which the nozzle is rotatable is substantially 90 to its own longitudinal axis.
  • the nozzle does not rotate completely about its axis of rotation. but oscillates about this axis.
  • the turbine is actuated by the flow of wash liquid. and the turbine should preferably be located at the entrance to. or in the wash liquid supply pipe.
  • the angle which the turbine blades make with the flow of wash liquid affects the speed of rotation of the turbine. and preferably it is the angle which the blades make with the longitudinal axis of the turbine which is altered.
  • Means can be provided which are capable of continuously varying the angle of the turbine blades.
  • this means of varying the angle of the blades of the turbine comprises a slidable rod. eo-axial with the axis of the turbine. the sliding of which rod along the axis ofthc turbine causes by means of linked levers. the variation of the angle the blades of the turbine make with the plane at right angles to the axis of the turbine.
  • the angle which the turbine blades make with the flow of wash liquid can however be varied by having fixed turbine blades and altering the angle at which the wash liquid impinges on the blades.
  • This arrangement would involve a number of substantially radial vanes placed in the wash liquid supply pipe immediately before the turbine, and a device for altering the angle which these blades make with the longitudinal axis of the wash liquid supply pipe, thereby altering the angle at which the wash liquid impinges upon the fixed blades of the turbine.
  • the speed of rotation of the turbine controls the speed of rotation of the nozzle housing and the speed of rotation of the nozzle.
  • the turbine is connected to a rotatable shaft which rotates with the turbine blades.
  • the slidable rod which varies the angle of the blades of the turbine is linked to a pivoted lever, the other end of which is moved by a rotatable cam.
  • Rotation of the cam causes longitudinal shifting of the slidable rod and hence variation of the angle of the turbine blades.
  • the nozzle can oscillate rather than completely rotate the machine is preferably provided with means for reversing the direction of rotation of the nozzle periodically.
  • This may be achieved by means of a slidable and rotatable clutch with two faces, each face of which can engage separately with two other rotatable clutches.
  • This slidable clutch is caused to slide periodically so that it engages first one and then the other of the other two clutches.
  • rotation of one of these clutches causes the nozzle housing and nozzle to rotate in one direction, whereas rotation of the other clutch in the same direction causes the nozzle housing and nozzle to rotate in the opposite direction.
  • the direction of rotation of the nozzle about the horizontal axis may be reversed while maintaining the direction of rotation of the nozzle housing in the same direction.
  • the direction of rotation of the nozzle can of course be reversed by other means. e.g., by means of a rotating partially toothed wheel engaging first one gear train, and then another gear train.
  • the speed of rotation or oscillation of the nozzle is very much less than the speed or rotation of the nozzle housing. This is obviously achieved by gear reduction and in practice the speed or rotation of the nozzle housing is usually from to 200 times, e.g. 20 to 60 times, that of the speed of rotation or oscillation of the nozzle.

  • Each pin 48 engages in a slot 49 (ohlique to the longitudinal axis) in the square end of the shaft. Longitudinal movement of rod 13 results in shifting of the levers 47 thereby altering the inclination of the blades 46 about their axes, two of which are shown at 50.
  • the operation of the tank cleaning machine is as follows:
  • Wash liquid usually water
  • the wash liquid passes down the vertical section of the wash liquid supply pipe 4 and eventually passes out through the nozzle 10.
  • Rotation of the turbine blades 46 causes shaft 12 to rotate and with it gears 14 and I5, and shaft 17. Since clutch member I8 is fixed to shaft l7 this clutch member also rotates. and as shown in FIG. 2 it engages clutch member I) which also rotates with clutch member 18.
  • Rotation of the clutch member 19 means that bevel gears 20 and 21 and shaft 22 on which the gears 20 and 21 are mounted also rotate.
  • Rotation of gears 20 and 2! also causes rotation of bevel gears 25 and 26, and shaft 7 and tube 6 respectively. Due to the difference in the gear ratio between gears 20/25 and 21/25 shaft 7 and tube 6 will rotate at different speeds. This in turn means that worm 8 and housing 5 respectively will rotate at different speeds. In practice it is usual for the gear ratios to be chosen so that shaft 7 and hence worm 8 rotates slightly slower than housing 5. This in turn means that worm gear wheel 9 rotates even slower.
  • bevel gear 26 now rotates in the opposite direction as also does bevel gear 25 (through bevel gear 20 fixed to shaft 22 which carries bevel gear 2] It can be seen therefore that when bevel gear 25 reverses direction so will shaft 7, and worm 8. This reversal of direction also means a reversal of direction of rotation of worm wheel 9, and this means that if nozzle l0 has been slowly rising it will now slowly descend, and vice-versa.

  • bevel gears 20, 25 of FIG. 2 are absent. and that the clutch member 19 is attached to the inwardlydirected face of bevel gear 2!.
  • Bevel gear 21 and bevel gear 24 are both meshed with a bevel gear 26 (which may alternatively be in the form ofa crown gear wheel, not shown, as will be apparent to those skilled in this art), and bevel gear 26 drives the single shaft 50 which extends downwards into the rotatably-mounted housing 5.
