Benefits of technology

[0009] The inventor has thus realised that for many cleaning and flushing purposes a traditional filter arrangement is unsuitable. For example a filter that is overly fine may require a high degree of maintenance and be subject to frequent blocking. Similarly a filter of too high a specification may require large amounts of energy, typically in the form of increased pressure to ensure that the a sufficient flow rate of water can be maintained through the unit. The unit of the invention provides for a relatively simple and rapid residency time that enables the water to be subject to a multi-stage settling and cleaning of gross contaminants.

Problems solved by technology

The used water may also incorporate a number of contaminant particulate materials which it would be undesirable to recirculate.
Further, it is not the purpose of the device to seek to remove all particulate contaminants but to clean the water sufficiently to allow recirculating of the water for further flushing and cleaning purposes.

Embodiment Construction

[0020] Shown in the drawings are cleaning devices 10 (FIGS. 1-4), 60 (FIG. 5), and 100 (FIG. 6). In each case the devices 10,60 and 100 operate on similar principles and have a number of features in common. The cleaning devices 10, 60, 100 are designed to be filled with a recirculating water supply and include a number of interconnected water holding tanks. Where like features are described in the drawings like numerals will be used to refer to these features.

[0021] Turning to the device illustrated in FIGS. 1-4, the cleaning device 10 includes an arrangement of three separate water holding tanks being a centrally located water return tank 12 and two outer water holding and supply tanks 14a, 4b respectively. In the embodiment under consideration the tanks of the device are constructed of steel and have been hot dip galvanized to improve their corrosion resistance. As can be seen to bets advantage in FIG. 2, the tanks 12, 14a and 14b have associated therewith water supply hoses 16a,...

Abstract

A cleaning device having one or more water holding tanks having associated water supply outlets connected thereto and an associated pumping means to effect a supply of cleaning water under pressure from each of the one or more holding tanks; the device further including one or more return tanks having associated therewith a water return tank and a water return inlet and associated suction means to allow collection of water into the one or more return tanks. The water holding tanks are in fluid communication with the return tanks and having a series of intermediary filter and baffle elements positioned in a water flow path such that water passing from a return tank to a holding tank is subjected to sequential settling action en route.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a cleaning device. In particular, the present invention relates to a device and method used for cleaning surfaces such as roadways. Further, the present invention relates to a cleaning device that permits the recycling of cleaning water. BACKGROUND OF THE INVENTION [0002] There are many occasions on which small areas of a road way or other similar surface might require cleaning and washing over a limited area. For example, where road works involve the cutting of sections of the road large amounts of dust and particulate concrete and so on are produced in the cutting action. Similarly, where spills of particulate matter occur quantities of the contaminant may remain after the road surface has been swept. In the past the response to such situations has been simple to flush the affected surface and allow the particulate material, dust and the like to be washed into a stormwater drain and carried away. However, it has now be...
