TITLE
MOBILE CLEANING APPARATUS AND METHODS
FIELD OF THE INVENTION
The present invention relates to mobile cleaning apparatus and methods of cleaning using such apparatus. In particular, embodiments of the present invention relate to high pressure, high volume mobile cleaning apparatus comprising a multi-stage boom and remote control head for applications such as, but not limited to the cleaning of industrial structures, such as storage tanks, io thickener tanks and structures that are typically found in refineries, mine sites and the like.
BACKGROUND TO THE INVENTION
Structures such as storage tanks and the like employed in industrial environments typically require routine cleaning and maintenance. For example, in view of the liquids and materials held in storage tanks commonly used in refineries, mine sites and the like, it is advisable for routine maintenance and monitoring of the tank conditions to be carried out. One problem with such tanks is that they may become fouled by sediment or the like that can hide any damage, rust or corrosion, or the like. It becomes necessary therefore to clean the interior of such tanks to prevent excessive damage or harm to the tanks or to the surrounding environment.
3400792V1
2019101072 17 Sep 2019
In some instances, storage tanks in the form of thickener tanks can contain extremely harmful substances, such as, but not limited to caustic substances, acids, traces of radioactive materials, such as uranium and lead based materials.
Such thickener tanks are found in a wide variety of mines and refineries.
Such storage tanks typically have diameters of around 10m to 70m. during the cleaning process, conventionally workers enter such tanks from a manway, elevated work platform (EWP), man basket off a crane, overhead walkway or otherwise enter the confined space of such tanks. Such workers generally must wear protective clothing and a safety harness, and if entering the confined space, must adhere to additional established safety protocols. If workers are using large water cannons from a walkway or the like, worker rotation is required due to the onset of fatigue through use of the water cannon. This can severely limit the work time inside the tank, particularly in hot weather.
Workers use high pressure hoses inside the tank to wash down sediment to expose the tank surface to a clean finish. Personal protective equipment and suits must be worn to resist exposure in the confined space. Such workers must undergo training prior to carrying out such work. Spotters are typically also employed to oversee worker safety and a safety plane and/or an evacuation plane is also required in the event of an emergency, particularly in remote sites, such as mines. Workers must also contend with the steep gradient of the tank floor that is present in many tanks and/or moving sediment containing extremely dangerous materials that may be found particularly in thickener tanks. Obviously this is highly dangerous and debilitating work.

For example, the body 28 can be a chassis of the mobile cleaning apparatus 10. In other embodiments, as shown in FIGS 1-3, the first stage 18 of the boom 14 is rotatably mounted to a platform 29 mounted to a forward position of the body 28 or chassis and behind a cab of the mobile cleaning apparatus 10.
A second stage 20 is coupled to the first stage 18 via a pivoting knuckle 30 and a hydraulic ram 16. A third stage 22 is similarly coupled to the second stage io 20. A fourth stage 24 is similarly coupled to the third stage 22. A fifth stage 26 is similarly coupled to the fourth stage 24. It should be appreciated that the present invention is not limited to a boom comprising five boom stages. Various numbers of boom stages and various lengths of boom stages can be used according to the application of the cleaning apparatus 10. According to some embodiments, each boom stage is about 5m to about 10m in length such that a vertical height of the boom 14 is about 25m to about 50m and a horizontal reach of the boom 14 is about 22m to about 46m. With additional reference to FIG 4, a cleaning head 32 is rotatably and tiltably mounted to a final stage of the boom 14. In the embodiment shown in FIGS 1 to 4, the cleaning head 32 is mounted to a distal end of the final, fifth stage 26 of the boom 14. Hence, the multi-stage boom 14 provides the reach and manoeuvrability required to position the cleaning head 32 relative to industrial structures to remotely clean the industrial structures.
In some embodiments, the cleaning head 32 is a spray head conventionally used for concrete spraying applications, such as concrete spraying applications
3400792V1
2019101072 17 Sep 2019 for underground mines and the like. In some embodiments, a spray head produced by Normet Oy, Finland as used in mobile concrete sprayers produced by Normet Oy can be used in the present invention, but the present invention is not limited to this specific spray head.

The receiver 42 is interfaced with the controller 40 such that activation of the transmitter 44 energizes the controller 40 to control tilt and rotation operations of io the cleaning head 32.
In some embodiments, the mobile cleaning apparatus 10 is a modified mobile concrete pumping truck. For example, a truck mounted boom pump, such as, but not limited to model JXRZ50 manufactured by Junjin of Korea, or a truck mounted concrete pump manufactured by Jacon, Australia, can provide a basis for modification. Modification of such concrete pump trucks by one skilled in the art in accordance with the description herein will enable the skilled addressee to arrive at the apparatus and perform the method described herein. Variations between different models of concrete pump trucks may be required, but will nonetheless fall within the scope of the present invention as defined by the accompanying claims.
According to another aspect, the present invention is directed to a method of cleaning industrial structures, such as tanks and the like comprising using the mobile cleaning apparatus 10 described herein.
3400792V1
2019101072 17 Sep 2019
According to another aspect, and with reference to the general flow diagram FIG 7, the present invention is directed to a method 200 of cleaning industrial structures, such as, but not limited to tanks and particularly thickener tanks.
The method 200 comprises at 202 positioning the mobile cleaning apparatus 10 in the vicinity of an industrial structure, such as a thickener tank, to be cleaned. The mobile cleaning apparatus 10 is positioned via a power source of the mobile cleaning apparatus, such as the engine 11.
The method 200 comprises at 204 moving the multi stage, articulated, io rotatable boom 14 of the mobile cleaning apparatus 10 adjacent the industrial structure to be cleaned. The boom 14 is coupled to the hydraulic system of the mobile cleaning apparatus 10 to control movement of the boom 14.
The method 200 comprises at 206 pumping cleaning fluid from the source 35 of cleaning fluid to the cleaning head 32 rotatably and tiltably mounted to the final stage 26 of the boom 14 via the pump 38 coupled to the power source 11 of the mobile cleaning apparatus 10 and via the conduit 34 coupled to the boom 14 and between the source 35 of cleaning fluid and the cleaning head 32.
The method 200 comprises at 208 controlling movement and operation of the cleaning head 32 relative to the boom 14 via the controller 40 coupled to the cleaning head 32 and the receiver 42 in communication with the controller 40 to receive signals from the remote transmitter 44. In particular, the angle of inclination and angle of rotation of the cleaning head 32 can be selected to accurately clean the industrial structure remotely.
3400792V1
2019101072 17 Sep 2019
The method 200 comprises at 210 controlling movement of the stages 18, 20, 22, 24, 26 of the boom 14 via the hydraulic system of the mobile cleaning apparatus 10 and the rams 16 of the boom 14 as required to position the cleaning head 32 above the desired location of the industrial structure to be cleaned.
The method 200 comprises repeating steps 208, 210 to position and manoeuvre the cleaning head 32 as required until the industrial structure is cleaned.
During use of the mobile cleaning apparatus 10, a worker is located on a walkway, standing platform or other safe, harm free position in line of site with the io cleaning head 32 to remotely control operation of the cleaning head 32 via the remote transmitter 44.
The stages of the multi staged knuckle boom 14 and articulation of the cleaning head 32 are controlled using the hydraulic system 15 for jetting high pressure water or other cleaning fluid against the interior of the tank or other industrial structure being cleaned. The multi stage boom 14 and cleaning head 32 are extremely manoeuvrable to be set up and used around the tanks. The apparatus 10 enables a higher pressure and volume of cleaning liquid to be used compared with hand held hoses or cannon. Additionally, no humans are exposed to any risk of heights, confined space, high pressure injection, physical harm or corrosive or toxic substances.
In the present invention the mobile cleaning apparatus is set up in one position on the perimeter of the tank or other structure to be cleaned. The multi stage knuckle boom 14 is unfolded to places the cleaning head 32 in to a position where cleaning is to be started. The desired cleaning liquid to be used couples to 13
3400792V1
2019101072 17 Sep 2019 pipe 36 via a suitable fitting which controls the flow of the cleaning fluid and in some embodiments, levels for the hydraulic driven pump 46.
From the safety of the platform or walk way using the remote control transmitter 44 the configuration of the multi knuckle boom 14 is easily maneuvered around inside the tank to access all areas. The 360 degrees slewing rotation and ability to tilt the cleaning head 32 through at least 105 degrees when desired enables efficient and safe cleaning of the tank interior or other industrial structure to be attained.
Hence embodiments of the present invention address or at least ameliorate io at least some of the aforementioned problems of the prior art. For example, the present invention allows for much safer, faster and environmentally desirable cleaning by completely eliminating the need for human workers to be present inside the tank being cleaned or in the immediate proximity of other industrial structure being cleaned. More particularly, the present invention enables shorter times for cleaning of tanks and other industrial structures, safer working conditions for workers in the cleaning process, eliminating the requirement to enter confined spaces, reducing worker fatigue and other potential risks.
In this specification, the terms “comprises”, “comprising” or similar terms are intended to mean a non-exclusive inclusion, such that an apparatus that comprises a list of elements does not include those elements solely, but may well include other elements not listed.
The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement or any form of suggestion that the prior art forms part of the common general knowledge.
