Definitions

  • a cleaning device for the interior of tanks, silos and the like has a foldable and spreadable framework carrying spray heads.
  • the framework can be folded to permit insertion through an opening, and can then be spread in the interior of the receptacle.
  • the interior framework can be rotated about a longitudinal axis, and each of the spray heads can in itself be rotated with reference to the framework.
  • the present invention relates generally to a cleaning device, and more particularly to a cleaning device for cleaning the interior of receptacles such as autoclaves, spray towers, silos, tanks and the like.
  • receptacles may be quite large, such as large tanks, autoclaves, spray towers, silos and the like.
  • these receptacles have a relatively small dimensioned opening through which the cleaning device must be inserted and withdrawn.
  • the spray heads or spray nozzles of such cleaning devices should be relatively close to the inner surfaces of the respective receptacle which are to be cleaned.
  • the cleaning device according to the present invention should be relatively simple in its construction, rugged, and reliable in operation.
  • one feature of the invention resides in a cleaning device, particularly for cleaning the interior of receptacles, which comprises a foldable and spreadable framework, and operating sired.
  • a plurality of spray heads is mounted on the framework and supply means is provided for supplying fluid under pressure to these spray heads.
  • Mounting means mounts the framework for rotation about an axis and drive means is associated with the framework and is operative for effecting rotation of the same about this axis.
  • the cleaning device according to the present invention can after its insertion through whatever opening into the respective receptacle, be rotated about the aforementioned axis and will thus provide for significantly improved cleaning of the surfaces in question.
  • the drive means may be pneumatic, it may be electric or hydraulic, or it may in fact be of any type suitable.
  • the drive means may have a drive unit which is driven via a partial stream of the cleaning fluid, and which causes the framework to be rotated about the aforementioned axis in steps, rather than continuously.
  • FIG. 1 is a slightly diagrammatic axial section through a hydraulic drive means of a cleaning device according to the invention
  • FIG. 2 is a diagrammatic partially sectioned illustration showing the remainder of the cleaning device which is driven by the drive means of FIG. 1, with the framework in folded condition;
  • FIG. 3 illustrates the components of FIG. 2 but in spread condition
  • FIG. 4 is a section taken on line IVIV of FIG. 2;
  • FIG. 5 is a view similar to FIG. 2 illustrating a further embodiment of the invention.
  • FIG. 6 is a partially sectioned view similar to FIG. 3 but illustrating the framework of FIG. 5 in spread condition.
  • reference numeral 1 identifies a water hose or pipe which is connected via a pressure tight screw coupling or fitting 2 with a hydraulic drive means 3.
  • the drive means 3 Connected with the drive means 3 by the aid of bolts 4,5 is the framework 6 which is illustrated in more detail in FIGS. 2 and 3.
  • Thedrive means or unit 3 has a center flow passage 32 having a longitudinal axis 30 and communicating with the water pipe 1. It is further provided with a bore 7 communicating with the passage .32 and diverting a means for folding and spreading the framework as de partial stream of the pressure fluid (such as water) which is introduced into the passage 32 from the pipe 1.
  • An automatically operating reversible control 8, whose operation will be described in more detail later, is provided and communicates with the passage 7.
  • the control 8 has a control slide 9 which, when it is in the appropriate position, permits water from the bore 8 to pass via additional bores 10 and 11 into a control chamber 12.
  • the drive unit 3 has an axially shiftable tube 14 which is sealingly engaged on a cylindrical portion thereof by a seal 13 which determines a cross section that is constantly under pressure, tending to shift the tube 14 and all components connected with it, namely a housing 15 with guide 16, a sealing arrangement 17 and the unit 8, downwardly (in FIG. 1) in the direction of flow of the pressurized liquid.
  • the housing 15 will be seen to have two cylindrical extensions 18 and 19 of which the former has a larger diameter than the latter but a smaller diameter than the remainder of the housing 15. Seals 20 and 21 are provided and cooperate with the projections or extensions 18 and 19 to seal the chamber 12. Due to the fact that the diameter of the extension 19 is smaller than the diameter of the tube 14, a part of the constantly and downwardly acting hydraulic pressure or force is compensated by the pressure acting upon the cross section determined by the seal 20. However, a substantial residual component of force remains, tending to displace the tube 14 in the direction of the flow of pressurized liquid, that is downwardly in FIG. 1.
  • the control slide 9 permits communication between the bores 7,10 and 11 so that water which is branched off the passage 32 via the bore 7 can enter the chamber 12. This causes the pressure in the chamber 12 to rise sufficiently for a relative movement of the housing 15 and the components associated with it in a direction counter to the flow direction of the liquid through the passage 32. In other words, the tube 14 is caused to move upwardly in FIG. 1.
  • the end portion of the tube 14 which is the upper end portion in FIG. 1 is provided with a plurality of spiral flutes 22 which mesh with similar internal flutes provided in a guide member 23, but loosely enough so as to permit a rotation of the tube 14 about its longitudinal axis 30 as the tube 14 is being lifted due to the pressure building up in the chamber 12.
  • the free wheeling unit 17, which is known per se, imposes this rotary movement on the housing 15 and via a slide 24 on the outer sleeve 25 at the lower end of the drive unit 3.
  • a thrust bearing 26 absorbs the non-compensated hydraulic forces which develop in the interior of the unit 3, and facilitates the movement of the tube 14.
  • the position illustrated in FIG. 1 is the position which the unit will have as the movement of the tube 14 in upward direction just begins. This movement continues until the slide 9 which moves with the tube 14 and the unit 8 buts with its upper free end against an abutment 27 provided for this purpose. Slightly continued movement of the tube 14 and the unit 8 causes the slide 9 to be displaced downwardly into the unit 8, thus blocking the passage of pressure liquid from the bore 7 into the bore 10 and at the same time communicating the bores 10 and 11 with the exterior of the drive unit 3.
  • the tube 34 (see FIGS. 1 and 2) of the framework (see FIG. 2) is connected with the drive unit 3 by means of the bolts 4 and 5. Its longitudinal axis 31 is coaxial and in axial alignment with the axis 30 of the passage 32.
  • the tube 34 extends to a distributor 33 which, as FIGS. 2-4 show, is in form of three nipples 35 which extend at right angles from the tube 34 and each of which carries a sleeve 36 that is rotatable on it.
  • the interior 37 of the nipples 35 communicates via a respective opening 38 with the interior of the tube 34 and flow apertures 39 and 40 are provided in the nipples 35 and 36 to permit liquid under pressure to enter from the tube 34 into the spray tubes 41 forming a part of the framework and having outer free ends each of which carries a spray head or spray nozzle 42.
  • spray heads 42 are each provided with two pairs of nozzles 43,44 which are offset relative to one another by and mounted so that they can rotate about the respective axis 45 as well as performing a stepwise rotary movement about the respective axis 46.
  • the tubes 41 are provided with bends 47. The manner in which the tubes 41 can pivot between the spread position shown in FIG. 3 and the folded position shown in FIG. 2 will be obvious from FIG. 4.
  • the framework is inserted in the folded condition of FIG. 2 through an opening in a receptacle whose interior is to be cleaned. If thereafter water or other liquid under pressure is admitted via the passage 32 into the tube 34, the piston 51, the arms 49 and the tubes 41 with the spray heads 42 move to the illustrated spread position of FIG. 3.
  • the nozzles 43 and 44 will start to turn about the common axis 45 and will also also begin to perform stepwise rotary movement about the axis 46.
  • the entire framework 6 will perform a stepwise rotary movement about the longitudinal axis 31 of the tube 34. This assures the desired intensity for cleaning of a surface with which the unit is juxtaposed.
  • FIGS. 5- and 6 there is provided a plurality of spray units 56 which carry respectivegroups of spray heads 57 and 58 each of which has two or more nozzles and can turn about an axis 59.
  • the group of spray, heads 57 is offset through 90 with reference to the group of spray heads 58.
  • the units 56 may be hollow so that pressurized liquid can be supplied via themto the spray heads 57 and 58 which latter are associated with control means moved in the interior of the respective unit 56 in longitudinal direction thereof and in a reciprocatory manner, in order to impose a rotary movement upon the spray heads about the axis 59 and 6,0.
  • FIGS. 5 and 6 is quite pronounced of that in FIGS. 1-4 to which reference may be had for details which have not been specially illustrated in FIGS. Sand 6. It will be seen that this latter embodiment also has a central tube 34 connected with the hydraulic drive unit 3.
  • the supply of pressurized liquid to the unit 56 is effected as in the preceeding embodiment via a distributor 33 and via supporting pipes 61 which are pivoted at 62 to the units 56 and which have pivoted to them in turn respective arms 61 which are actuated in the. same manner as described in FIGS. 1-4 by the piston 51.
  • the tube 34 in the embodiment of FIGS. 5 and 6 has an end portion with a downwardly extending projection or extension 65 which there are pivoted arms 66 whose other ends are pivoted to the respective units 56.
  • the arms 66 in conjunction with the tubes 61 assure that the unit 56 will move in complete parallelism with the longitudinal axis of the tube 34 during the spreading or folding of the framework.
  • the piston 51 here surrounds the tube 34 and, depending upon its location, also the extension 64 thereof, intermediate the distributor 33 and tube 61 on the one hand, and the pivot point of the arms 66 on the other hand.
  • a cleaning device particularly for cleaning the interior of receptacles, comprising a foldable and spreadable framework including a plurality of elongated members; mounting means including a pipe pivotably mounting said framework for rotation about an axis; drive means associated with said framework and operative for effecting rotation of the same about said axis; operating means for folding and spreading said framework, including a sleeve slidable along said pipe, linkage arms articulately linking said members with said sleeve, and moving means for effecting movement of said sleeve along said pipe between two end positions in which said framework is respectively folded and spread; a plurality of spray heads mounted on said framework; and supply means for supplying fluid under pressure to said spray heads.
