Abstract
A tool for cleaning hard, nonabsorbent surfaces, of various compositions, such as concrete, ceramic tile, or the like, and of varying degrees of roughness or smoothness. The tool includes a movable platform with an outer housing and a structure which defines an interior cavity, the structure being spaced apart from the housing and nested beneath it. A liquid used in the cleaning operation is fed into the cavity through two nozzles located on the ends of a tube. Disposed horizontally, the tube is rigidly attached, in its midsection, to a hollow shaft which is supported vertically by a rotatable bearing/seal component. The latter allows a stationary liquid supply hose to deliver liquid at high pressure, via the hollow shaft, to the tube. The nozzles are positioned so that their flow streams discharge downwardly at a slight angle to the vertical. So discharged, the flow stream imparts a tangential force to the tube causing it to rotate. The rotation of the tube causes the fluid to be applied in a pulse-like sequence, enhancing cleaning action and greatly reducing the rate at which cleaning fluid is consumed. The space between the outer housing and the structure is supplied with a vacuum which sucks up sprayed liquid and any loose dirt, transporting the mixture to a portable storage tank. After the platform passes over a work surface, very little liquid is left thereon, making the tool suitable for indoor cleaning. A filter is provided so that dirt in the cleaning fluid itself can be removed, and the fluid reused.
Description
- As is well known, high pressure water, with or without cleaning chemicals, can be utilized to clean both tiled and bare concrete floors. However, in the past, high pressure liquid cleaners have been found suitable only for use outside of buildings because of the large quantity of water left behind on the floor after a cleaning operation.
- The object of this invention is to provide a portable apparatus, employing a high pressure liquid spray, which can be used to clean floors, whether the floors are tiled or have exposed concrete and wherever they are situated.
- A further object of this invention is to provide such an apparatus which is highly maneuverable in all directions, so that it can be easily moved around objects within a building.
- In accordance with the present invention, there is provided an apparatus which can be used to deliver a high pressure liquid spray to such a floor and simultaneously remove both the liquid and any dirt loosened by the spraying action in such a way that a minimum of the sprayed liquid is left on the floor.
- The apparatus comprises a movable platform having a double-walled structure which defines an interior cavity. Liquid under high pressure is fed into the cavity through two nozzles located on the distal ends of a tube, which forms the arms of an inverted “T”-shaped element. Disposed horizontally, the tube is both fluidly and rigidly connected to a hollow shaft which is supported vertically by a rotatable bearing/seal component. Secured to the double-walled structure, the rotatable bearing/seal component allows a stationary liquid supply hose to deliver liquid at high pressure, via the hollow shaft, to the tube. A suitable rotatable union/seal component is Model No. 927, manufactured by the Deublin Company, Waukegan, Ill., and distributed as part No. 85,790,004 by the Chemical Feed Equipment Company, Norcross, Ga.
- The nozzles themselves are positioned so that the discharge of each is directed downwardly and at a slight angle to the vertical. The nozzles are so oriented that their discharges impart an unbalanced, tangential force to the tube causing it to rotate about the longitudinal axis of the shaft. In the preferred embodiment, this slight angle measures, by way of example, approximately 10 degrees. As the tube rotates, the cleaning fluid is applied in a pulse-like sequence, enhancing cleaning action and greatly reducing the rate at which cleaning fluid is consumed.
- Terminating downwardly in at least one narrow opening which rims the lowermost edges of the double-walled structure is a passageway, defined thereby, which is fluidly connected to an external vacuum source. The vacuum source is employed to suck up the sprayed liquid and any loose dirt, transporting the mixture to a portable storage tank. After the platform passes over a work surface, very little liquid is left thereon, making the the apparatus suitable for indoor cleaning.
- Preferably, a filter is provided so that dirt particles entrained in the cleaning fluid itself can be removed; and the fluid reused.
- A high degree of maneuverability is achieved with the apparatus by mounting the platform atop two sets of cantilevered arms in which each arm rests on a caster roller. In the preferred embodiment, one set of arms extends downwardly and forwardly, and the other downwardly and rearwardly, of the platform.

- FIG. 5 is a front elevational view of the platform in the cleaning apparatus according to FIG. 1;
- FIG. 6 is a left side elevational view of the platform in the cleaning apparatus according to FIG. 1;
- FIG. 7 is a left side elevational view of the rotating tube with nozzles within the platform, the remainder of the platform being shown in cross-section, the cross-section being taken along line7-7 in FIG. 3;
- FIG. 8 is a schematic of support equipment for the cleaning apparatus according to FIG. 1; and
- FIG. 9 is a perspective view of the support equipment according to FIG. 8 and a trailer in which the support equipment is mounted.
- In accordance with the present invention, an apparatus, which is indicated generally by the
reference numeral 10, comprises amovable platform 11 having anouter housing 12 and aninner structure 13. Nested beneath thehousing 12, thestructure 13 is spaced therefrom, forming a central cavity which opens downwardly but is otherwise surrounded byhollow sidewalls sidewalls surface 40 to be cleaned. - Affixed to the
sidewalls seals seals - Within the central cavity, a
tube 35 equipped withnozzles 36 is mounted on a hollow shaft (FIGS. 4 and 7). A stationaryfluid supply hose 28 and thetube 35 are fluidly connected to distal ends, respectively, of a rotatable union/seal component 34 which penetrates both thehousing 12 and the structure 13 (FIG. 7). A suitable rotatable union/seal component is Model No. 927, manufactured by the Deublin Company, Waukegan, Ill. Rigidly attached to a flange which extends laterally from thecomponent 34 is a spacer, concentric therewith (FIG. 7). The spacer, juxtaposed between thehousing 12 and thestructure 13, not only holds them in assembled relation but also forms an airtight seal with each of them. - Oriented so that any spray discharged from the
apparatus 10 will be directed downwardly and at a small angle offset from the perpendicular to thework surface 40, thenozzles 36 comprise propulsion means for thetube 35. With thenozzles 36 so oriented, their flows impart an unbalanced, tangential force to thetube 35, causing it to rotate about the longitudinal axis of the shaft. In the preferred embodiment, this small angle measures, by way of example, approximately 10 degrees. - Moreover, the rotating spray mechanism enhances the cleaning action of the
apparatus 10 because thesurface 40 beneath theplatform 11 is inundated in a pulse-like sequence, rather than constantly. In between pulses, dirty water is evacuated and any loosened debris subjected to suction forces, thereby expediting the cleaning process. - Sucked through the narrow opening rimming the cavity beneath the
platform 11 and into the space between theouter housing 12 and thestructure 13, sprayed liquid and any loose dirt entrained therein are transported, via thevacuum hose 15, to a portable recovery tank 38 (FIGS. 8 and 9). - After the
platform 11 passes over awork surface 40, very little liquid is left thereon, making theapparatus 10 suitable for indoor cleaning. It has been found experimentally that for a medium roughness concrete surface, water capture is good when theseals surface 40. - In the preferred embodiment, the
apparatus 10 uses water or water mixed with a chemical as the cleaning fluid. The cleaning fluid is stored in asupply tank 31 in atrailer 30. A manually controlledvalve 26 fluidly connectsliquid supply hoses supply tank 31 andrecovery tank 38 having capacities of approximately 330 gallons and 175 gallons, respectively, have been found to be suitable for routine cleaning jobs using aplatform 11 with a footprint measuring about 20 inches on a side. - The
apparatus 10 is preferably powered by a dual hose connection to atrailer 30 in which are housed support equipment including a high pressureliquid pump 32 and ahigh volume blower 41. Thepump 32 andblower 41 are driven, viapulleys pump 32 has flow rate of 4 gallons per minute at a pressure of 3500 pounds per square inch; and theblower 41 has an air flow rate of 280 cubic feet per minute. Theair supply hose 15 and theliquid supply hose 33 can be wound onspools - Illustrated in FIG. 8 are two embodiments of the support equipment for the
apparatus 11. Support equipment components shown in solid lines in FIG. 8, in combination with theapparatus 10, comprise an once-through system in which the recovered cleaning fluid, together with any particulates and other contaminants removed in the cleaning process, is stored in therecovery tank 38. - In an alternate embodiment which includes the support equipment components shown in both solid and dashed lines on FIG. 8, the recovered cleaning fluid is passed through a
filter 51 en route to therecovery tank 38. Valve 46 in arecycle line 39 can be opened periodically, withmotor 29 shut down, to allow the filtered cleaning fluid to drain into thesupply tank 31 for reuse. - In the preferred embodiment, the
platform 11 weighs under 30 pounds and is rolled about on caster rollers 24 (FIGS. 1 through 7). Mounted atop two sets of cantilevered arms in which each arm rests on acaster roller 24, theplatform 11 is highly maneuverable in all directions and easily moved around objects in a building. In addition, a handle 25 for propelling and guiding theplatform 11 is pivotally attached thereto bybrackets 27 mounted on thehousing 12. - It is understood that those skilled in the art may conceive other applications, modifications and/or changes in the invention described above.
