Preferably there are two contra-rotating brushes, surrounded by a skirt and the suction head may also surround the cleaning head and spray means.

Description

2352166 CLEANING SYSTEM This invention is concerned with a cleaning system
by which an acidic cleaning material is applied to a soiled surface. Such solutions are useful for removing, for example, rubber deposits on airport runway surfaces and oil spillages and oil deposits on petrol filling stations and garage forecourts. Conventionally, such cleaning solutions are applied manually to a soiled surface, subjected to manual scrubbing, then treated with a neutralising agent, and the deposit is removed with a rinsing jet.
This is a time-consuming process, and there are environmental problems if the rinsing solution effluent and removed deposits are allowed to enter the drainage system.
In its broadest aspect the present invention provides a cleaning method in which a cleaning solution is applied to a cleaning head containing a powered brush or to a soiled surface, the cleaning head is moved across the soiled surface so that the brush works the cleaning solution into any soil deposits, a rinse solution is applied to the surface area which has been cleaned, and neutralised cleaning solution is removed by a suction head moved across the cleaned surface.
Preferably the cleaning and suction heads and nozzles for supplying cleaning and Z rinse solutions are mounted together as a unit so that they can be moved together across an area to be cleaned.
In one embodiment, which is preferred, the cleaning solution may be an acidic cleaning solution and the rinse solution an alkaline rinse solution, but alternatively the cleaning solution may be a solvent based cleaning solution.
In another aspect, the invention provides a cleaning apparatus for cleaning a soiled surface comprising, a cleaning head containing a movable brush, means for moving the brush, means for supplying a cleaning solution to an area of soiled surface adjacent the apparatus or to the cleaning head whereby to apply the cleaning solution to said adjacent area, means for supplying a rinsing solution to said adjacent area and a suction head for sucking up neutralised cleaning solution from said adjacent area.
2 The brush may be rotatable or movable in other ways such as back and forth or from side to side to provide the necessary scrubbing effect.
Typically, the apparatus including the cleaning head, and suction head are mounted on means such as wheels or skids. They may be mounted in line, so that as the apparatus is advanced across a soiled surface, each head passes sequentially over the same area.
Alternatively the suction head may be arranged to surround the cleaning head and spray means, so that it is effective in all directions of movement of the apparatus.
The apparatus may also support supply lines for the cleaning and rinsing solutions, a suction line for removal of neutralised solution, and a power line, electrical or hydraulic, for driving a motor to rotate the brush. The apparatus is preferably provided with runners or wheels to assist in movement of the apparatus between areas to be cleaned. Wheels are preferably mounted at one end only of the apparatus allowing the weight of the apparatus to be at least partially bome by the brush in engagement with a soiled surface. Suitably, the supply lines and power lines are gathered together and located in an arm with a handle, by which an operator may manoeuvre the cleaning apparatus to a desired position, and the supply and power lines lead to a remote source of power, solutions and suction. Control means for the supply and power lines may be provided at the remote source and/or on the handle.
Most suitably the supply sources are mounted on a vehicle by which the cleaning apparatus may be transported to a soiled surface site, where the cleaning apparatus may be unloaded and guided over the soiled surface by an operator A truck-mounted aenerator may be used to actuate pumps to supply cleaning solutions C ID under pressure to the cleaning apparatus, also to operate a suction pump for removal of neutralised solution, and to provide electrical or hydraulic power to rotate the brush in the cleaninQ head. 30 The cleaning apparatus is most suitably pushed by an operator across the soiled surface. However. if required the cleaning apparatus may be provided with driven 3 wheels, or alternatively the cleaning head and nozzles may be provided as part of the structure of the truck, which supports the generator and remote equipment, so that the truck is driven across the sofled surface to perform the cleaning.
Preferably, means are provided to create a downward pressure on the cleaning head.
In a powered apparatus, this could be by means of hydraulic pressure applied from the apparatus or truck to the cleaning head. In a manually operated system it is most conveniently provided by the static weight of the cleaning head, which may be supplemented by removable weights.
The cleaning head is preferably provided with a skirt surrounding the brushes so as to confine the cleaning solution within the area of the soiled surface being contacted by the rotating brushes. Conveniently the suction head is an annular nozzle provided around the circumference of the skirt.
In a modification of this invention, the acidic cleaning solution may be replaced by a solvent-based cleaner. The use of a rinse conveniently the alkaline rinse mentioned above, still enhances the cleaning process.
Two embodiments of cleaning apparatus for acid cleaningWkaline rinse in accordance with the present invention are illustrated, by way of example only, by the accompanying drawings in which Figure I is a schematic view of a first embodiment of the invention showing a cleaning head mounted on a wheeled trolley; Figures 2 A and 2B are respectively schematic underside and side views of the cleaning head assembly of the apparatus of Figure 1; Figures 3)A and 3)Bare respectively underside and ftont schematic views of an alkaline spray head assembly of the apparatus of Figure I) Figure 4 is a schematic view of a control panel mounted on a handle for the trolley of Figure 1, 4 Figure 5 is a schematic diagram showing the connectivity of a cleaning head as shown in Figure 1, and a remote supply of power and fluids, Figure 6 is a side view of a second embodiment of the invention (where appropriate, the same reference numerals being used for similar items in the drawings of the second embodiment as the drawings of the first embodiment), Figure 7 is a part sectional side view of part of Figure 6, and, Figure 8 is a sectional front view of part of the apparatus of Figure 6.
Referring to Figure I of the accompanying drawings, in one embodiment of the invention, a wheeled trolley 1 is provided to support a cleaning head 2. In the cleaning head 2, a hydraulic motor 3 drives a rotatable brush 20 shielded by a peripheral skirt 4. Wheels 3) I are provided at the rear of the trolley so that the trolley can be pivoted about the wheels to lift the brush from the ground. The wheels are positioned so that, in use, the weight of the trolley is primarily supported by the brushes, thus applying downward pressure on the brushes, the wheels only being used when moving the apparatus between areas to be cleaned.
Also within the head 2 is one or more nozzles 21 supplied by a hose 5 through which an acidic cleaning solution is supplied into the head 2. A power tine 6 provides electrical current to the motor 3. Also mounted on the trolley is a spray nozzle set 7 which receives alkaline rinse solution from a hose 8. Rear-wardly of the spray nozzle 7 is a linear suction nozzle connected to a suction line 10.
In use of the cleaning apparatus, the trolley is advanced across a soiled surface, (such as a runway surface on which has been deposited rubber from aircraft tyres or a petrol station forecourt on which oil has been deposited), with the brush or brushes in the cleaning head rotating and acidic cleaning solution being supplied into the head. The acidic solution is retained in the head 2 by the skirt 4 so that it can be worked into the soil deposit by the brushes within the head. When the surface is satisfactorily cleaned, (i.e. the acidic cleaning solution has dissolve or broken up the deposit) the trolley I may be advanced across the cleaned area and an alkaline rinse solution sprayed onto the clean surface from the nozzles 7 to neutralise the acid. The neutralised solution and removed deposits are sucked into the suction nozzle 9 formed in or by the skirt.
The acidic cleaning solution and alkaline rinse solution may be deEvered simultaneously so that as the trolley is advanced across a soiled surface, the rinsing solution is applied immediately after an area has been cleaned. Alternatively the acidic solution may be applied on its own, while an area is subjected to cleaning and the alkaline rinse solution delivered sequentially after the cleaning has been completed.
Suitably, the trofley I is moved across a soiled surface using a push arm I I which is connected to the wheeled end of the trolley 1. A handle urn't 12 on the end of the push arm 11 contains controls such as a lever arm 13 controlling defivery of the acidic solution, such as by operating a solenoid valve in the supply line, and a similar lever arm 14 for control of supply of the alkaline solution. These may be operated simultaneously or sequentially as in the cleaning schemes discussed above.
Additionally, a switch 15 allows the suction at the nozzle 9 to be switched on or off, and an override switch 16 allows the motor for the scrubbing brushes to be disconnected from the power supply.
Hoses 5, 8 and 10 connect the control valves in the handle to a manifold on the cleaning head and then to the spray and vacuum nozzles.
To increase the abrasion pressure of the brushes on the soil deposit, a weight or weights may be secured to the upper surface of the cleaning head 2. These weights may be removable to adjust the cleaning pressure.
Further supply lines lead from the handle unit to a truck-mounted generator 25 which powers pumps 17,18 for supplying the acidic and alkaline solutions and a suction pump 19 for removing neutralised solution. The supply pumps 17,18 are connected to supply tanks 26,27 for the acid solution and alkaline solution also carried on the truck, and the suction pump 19 delivers neutrallsed solution and soil deposits to a waste tank 22 also mounted on the truck.
6 The generator 25 also supplies hydraulic fluid to the motor on the cleaning head.
The exhaust fi7om the generator 25 may be passed through a heat exchanger 24, through which the acidic solution supply line also passes, so as to heat the acidic solution for optimum cleaning, Because the alkaline rinse solution may be applied directly to the cleaned surface immediately after the acid solution/brushing treatment, it is possible to use a more highly acidic cleaning solution than is the case when the acid solution and alkaline solution must be poured manually onto a surface by an operator.
The cleaning system may be used with conventional acidic and alkaline cleaning solutions such as "Acid Clean", supplied by Capitol Cleaning, and Alkaline Rinse supplied by Prochem.
In a typical embodiment, the acidic cleaning solution, heated by an in line heat exchanger, is delivered through a 100psi hand controlled pump feed mechanism into the inside of a rotating polypropylene scrubbing head, surrounded by an anti-splash skirt. The solution is then scrubbed into the soiled surface by a brush or brushes revolving at 120rpm. Behind the scrubbing head, is a jet system working from a 1000psi pump, which sprays an alkaline solution, both rinsing and neutralising the now dirty cleaning solution, This is followed by a wet suction with a 220cfin water lift capacity. This extracts the now neutral solution containing all the removed dirt from the surface leaving it both dry and clean and in a pH neutral state.
