Definitions

  • An apparatus for the cleaning of the internal surfaces of receptacles of substantially any configuration and type comprises a head rotatable about the axis of an inlet conduit for the cleaning fluid and carries at least one rotatable nozzle arrangement having tangentially oriented nozzles communicating via the head with the conduit for rotation of the nozzle member upon ejection of the cleaning fluid through the nozzles thereof.
  • a hydraulic motor is coupled with the head for rotating the same about the conduit axis and relatively thereto, the motor being driven at an adjustable rate by fluid delivered by a hydraulic pump coupled with the nozzle box and driven thereby.
  • the present invention relates to an apparatus for the cleaning of conduits and containers of substantially all configurations, sizes and types and, more particularly, to an apparatus having a rotatable nozzle head through which a cleaning fluid is ejected to subject the containers of surface cleaning, as well as to a method of operating such a device.
  • the latter system operates with a complex transmission between the rotating housing and the nozzle head, thereby rendering it difficult if not impossible to adjust the transmission ratio. Furthermore, the lack of adjustability in the latter system renders the arrangement suitable only for the strip-wise cleaning of tanks and conduits and eliminates the possibility that the device may be used for the surface cleaning of tanks of all configurations and sizes.
  • an apparatus or device for the cleaning of containers, tanks and conduits of substantially all configurations, sizes and types which comprises an inlet conduit for delivering the cleaning fluid to the device, a head rotatable relative to this conduit about a first axis which may be parallel to or coincide with the axis of the conduit and coincide with the axis of the head, and a nozzle assembly communicating with the conduit through the head and rotatably mounted thereon for rotation about a second axis substantially perpendicular or orthogonal to the axis of rotation of I the head.
  • the mechanical input of the hydraulic pump is the rotating nozzle assembly and a first transmission means operatively connects this assembly with the input member of the hydraulic pump.
  • This first transmission means is preferably a gear drive, but may be a chain, belt or like transmission.
  • a second mechanical transmission couples the output member of the hydraulic motor with the head of the device for rotating same upon hydraulic pressuriza tion of the motor, a duct network being provided between the hydraulic pump and motor to drive the latter.
  • This network may include valve means for varying the throughflow of fluid to the hydraulic motor and, therefore, the rate of operation of the latter relative to the operating rate of the pump, thereby establishing a variable transmission ratio between the angular velocity of the nozzle assembly and the angular velocity of the head.
  • the method of operating a rotating nozzle arrangement for the cleaning of containers therefore, comprises the step of ejecting the cleaning fluid from a rotating nozzle assembly and thereby driving the latter by reaction force, displacing a hydraulic fluid, e.g. the cleaning liquid or another liquid medium, at a rate controlled by the rate of rotation of the nozzle assembly, and rotating the head carrying the nozzle assembly about its axis at a rate. controlled by the fluid displacement generated by the rotating nozzle assembly.
  • a hydraulic fluid e.g. the cleaning liquid or another liquid medium
  • the housing carries the hydraulic pump which is mechanically coupled with the nozzle assembly to be rotated thereby.
  • the housing may carry the hydraulic'motor which is connected with the pump via duct means rotatable with the housing, the output member of the motor being operatively connected with the conduit via a transmission as noted earlier.
  • the output of the hydraulic pump is a function of the angular velocity of the rotating nozzle assembly while the rotational speedof the housing is a function of the rate at which hydraulic fluid is supplied to the latter via the pump. Since a valve is provided in the duct means, the through-put to the motor may be adjusted readily and hence the ratio of the angular velocity of the housing and the angular velocity of the nozzle assembly may be established with substantially infinite control at any rate desired for the particular cleaning task.
  • Bothfluid pump and fluid motor are carried by the housing and rotated together therewith. The overall rotation rates are determined, therefore, by the rate at which fluid is ejected from the nozzle assembly.
  • the fluid pump is driven by a mechanical transmission from the nozzle assembly and is mounted upon the rotating housing while the fluid motor is carried bythe housing and has its output shaft mechanically linked with an angularly fixed member, e.g. the conduit mentioned earlier. While these mechanical transmissions have fixed ratios, this is not significant since the important ratio is determined by the fluid flow between the pump and motor as noted earlier.
  • the passages 35 and 36 are axially aligned, while lying at right angles to the axis 6.
  • the axes 5 and 6 may be coplanar as will be apparent from FIG. 2, the common plane being the plane of the paper.
  • the rotatable head 1 is also formed with a pair of tubular bosses 37 and 38 extending in opposite directions along the axis 5 and hence coaxially surrounding the passages 35 and 36, the bosses having shoulders as represented at 39.
  • the bosses 37 and 38 are provided with a pair of diametrically opposite ports 40 and 41 (FIG. 2) communicating with the respective passage 35 or 36 and opening into an annular space 42 defined around the respective boss 37 or 38 by a hub 43 rotatably mounted thereon.
  • Each hub forms part of a rotatable nozzle carrier or head, generally designated at 2, which is rotatable about the axis 5 and carries a pair of radially outwardly extending pipes 44 and 45 welded to the hubs and rotatable therewith in planes P and P which are perpendicular to the axis 5 but parallel to one another and to the axis 6.
  • two such nozzle assemblies 2 are provided upon the head 1, it being noted that the system may accommodate any number of such assemblies, the head 1 being formed with a corresponding boss 37 or 38 upon which the assembly isjournaled to prevent escape of fluid in the region of the hub a pair of seals 46 and 47 are disposed within the chamber 42, circumferentially surrounded at boss 37 or 38, and axially flank the ports 40 and 41 while sealingly engaging the cylindrical inner surface of the hub 43 and permitting free rotation of the latter while confining the ,high pressure liquid. While only two nozzles are shown to be mounted on each hub, it will be appreciated that any number of angularly equispaced nozzles can be used.
  • Each of the pipes 44, 45 of the respective nozzle 3 communicates via a radial aperture 49, 50 in the hub with the annular compartment 42 and hence receives the cleaning fluid at high pressure.
  • the pipes 44, 45 are bent substantially at right angles at 51 and 52, as illustrated in FIG. 1, in opposite directions with respect to the plane P" defined by the axes 5 and 6.
  • the nozzles 3, formed at these bent extremities of the pipes, are of frustoconical configuration to increase the velocity of the jets ejected therefrom. It has been found to be advantageous to orient the corresponding nozzles of the assemblies in opposite senses to that the assemblies are rotated in opposite senses as well.
  • the nozzles 3 are formed with cylindrical outer peripheries 53 projecting beyond the remainder of the head 1 and the apparatus carried thereby, thereby limiting the possibility of damage to the head structure (see FIG. 2).
  • the or each nozzle assembly 2 is fixed, e.g. by bolts 54 to a gear 14 which is rotatable together therewith about the axis 5 upon the rotatable head 1.
  • the gears 14 form, with gears 15, fixed-ratio mechanical transmission driving respective hydraulic pumps 7.
  • the latter are carried by plates 55 bolted at 56to the housing 1 and have input shafts 57 carrying the pinion gears 15.
  • the nozzle assemblies 2 are rotated at a rate determined by the pressure and quantity of the cleaning fluid delivered to the nozzles and drive the pumps 7 at a rate likewise proportional to the quantity of cleaning fluid dispensed by the apparatus.
  • the head or housing 1 is, in turn, provided with a hydraulic motor 8 and, preferably, carries this motor via a support plate 58 best seen in FIG. 1.
  • the motor 8 has an output shaft 59 rotatable about an axis parallel to the axis 6 and carrying a pinion gear 13 which meshes with the fixed sun gear 12 bolted at 60 to the fitting 4.
  • hydraulic pressurization of the motor 8 will drive shaft 9 and cause its gear 13 to orbit the angularly fixed gear 12 at a rate determined by the throughflow of this hydraulic motor.
  • the gear 12 is coaxial with members 4 and 11 and is angularly fixed, the motor 8 must orbit the axis 6 and thereby carries the housing 1, together with the nozzle heads 2, therearound.
  • the transmission 10, like transmissions 9, is a mechanical fixed-ratio transmission.
  • the hydraulic pump 7 and the hydraulic motor 8 are connected in a fluid circuit with a reservoir 16, diagrammatically illustrated in FIG. 1 with the remainder of the ducts connecting the pumps and motors and mounted upon the head 1.
  • a discharge line 17 delivers the high-pressure fluid to the motor 8 via a throttle valve 20 and a three-way valve 21, the intake of pump 8 being represented at 61.
  • a further passage 18 extends to a reservoir 16 and the latter is also provided with a branch 19 from the outlet side of motor 8.
  • the input to the pumps 7 is represented by a line 62 deriving from the reservoir 16.
  • a bypass valve may be provided in shunt across the pump to regulate the net fluid flow through the motor.
  • valves 20 and 21 determine the throughflow of the fluid displaced from the pump 7 to the motor 8 and, therefore, the transmission ratio between the rotary nozzle assemblies 2 and the rotary housing 1 and through this transmission ratio is in finitely adjustable.
  • the speed of the nozzles assemblies is determined by the rate at which the cleaning fluid is ejected from the nozzles.
  • An apparatus for the cleaning of containers, conduits and the like comprising:
  • a head mounted on said conduits for rotation about a first axis
