Definitions
- Mobile spraying device in particular for spraying treatment solutions for the removal of coverings and for the disinfection of water containers and other water supply devices
- the invention relates to a new mobile sprayer, in particular for spraying treatment solutions for
- Removal of coverings in or on water containers and other water supply equipment or for disinfecting it is intended and comprising a spray lance for spraying a treatment solution and a pump for supplying the treatment solution from a storage or mixing container under the desired pressure to the spray lance.
- the mobile sprayer can also be used for other purposes, in which any treatment liquids, in particular those water-based or with the consistency of aqueous solutions, must be sprayed over a large area by an operator, wherein the operator moves in front of the surfaces to be sprayed.
- any treatment liquids in particular those water-based or with the consistency of aqueous solutions, must be sprayed over a large area by an operator, wherein the operator moves in front of the surfaces to be sprayed.
- the coverings to be removed have a high mechanical strength and considerable chemical resistance. In order to be able to remove them effectively, it is therefore necessary to use special treatment solutions which are aqueous solutions of suitable chemicals.
- the solutions can, according to their exact composition, have a considerable aggressiveness or corrosiveness and are often mixed together just before they are used from suitable components.
- the treatment solution In order to remove the coverings from the walls of, for example, municipal drinking water tanks, which are generally sized underground swimming pools, the treatment solution must be uniformly applied by an operator in the required quantity with a low-pressure spray lance on the walls. be sprayed, with the operator slowly wanders through the entire drinking water tank.
- drinking water is a foodstuff
- removal of the toppings may only be carried out under strict hygienic conditions.
- the drinking water tanks must therefore also be subjected to a final disinfection with suitable disinfectant solutions prior to their recommissioning after the removal of the surface. Even such a disinfectant solution must be sprayed over a large area.
- the operator can usually not carry the entire liquid supply with him, but receives the liquid supplied via hoses that feed the liquid from a storage or mixing container, which is also used for mixing the treatment solution from their
- Diaphragm metering pump with an associated compressor for generating compressed air.
- the pump is connected to a 10 to 100 m long hose that connects the pump to the spray lance used by the operator.
- Another basic type uses an electromotive pump mounted on a base plate and / or a support is arranged.
- both the compressor and the electric motor are operated with a mains alternating current of 230 V / 50 Hz, they must not be taken into the drinking water tank because of the risk to the operator in the humid environment. Another risk is the gear oil, which must not get into a drinking water tank, which could occur, for example, in a membrane breakage. It is therefore currently prohibited to take the pumps and the associated drive motors with them into the clean drinking water tank. They must therefore be placed outside the drinking water tank to be cleaned and are connected to the spray lance over long hoses. The long hoses ⁇ lead to high friction losses, which is why pumps or
- the present invention is based on an analysis of the disadvantages of the previous practice, as a result of which the inventors came to the conclusion that new mobile sprayers are needed which can be taken into the drinking water container, since they do not have the above potential risks of the known mobile ones Sprayer go out. ' The present invention provides such a new mobile sprayer. Its basic features are given again in the following claims and will become apparent to those skilled in the art from the following more detailed description of the invention.
- the pump used is a chemical-resistant, self-priming and dry-proof liquid pump which is supplied with low voltage (usually 12-48 V), e.g. can be operated with economical 24 V, preferably from batteries or possibly also suitable transformers.
- low voltage usually 12-48 V
- 24 V preferably from batteries or possibly also suitable transformers.
- Such pumps are available from specialist companies and are usually based on the principle of oscillating positive displacement pumps.
- the rotational movement of a drive shaft via an eccentric system is converted into a vibrating (oscillating) movement in known manner and transmitted via a connecting rod to a pump diaphragm.
- the membrane movement ensures the proper pumping or conveying process.
- Such pumps operate virtually noiseless and contain no engine oil that can leak and get into a drinking water tank.
- the pump preferably draws power from powerful accumulators which are mounted together with the pump on a portable or wheeled plate and then, when their power is exhausted and they need to be replaced or charged, easily against fresh
- Accumulators can be replaced. It results in a low overall weight of the mobile sprayer, which allows the operator to easily transport the latter wherever it is needed.
- this second set of batteries is connected to an included charger and can quickly and easily replace the first set if its performance deteriorates.
- low voltage such as a voltage up to 48 V
- the electrical equipment can be operated without safety problems in facilities such as drinking water tanks.
- the new mobile sprayer is designed to ensure uninterrupted work at all times and to save time when cleaning containers from the o.g. Belong to the past.
- the mobile sprayer can be taken into the drinking water tank, eliminating the hitherto required meter-long hoses. It becomes possible also to make the storage and mixing container part of the mobile sprayer, e.g. mounted on a wheeled common base plate. But it can also be easily placed inside the clean drinking water tank in convenient proximity to the work area and e.g. used in conjunction with a portable sprayer working unit.
- the additional equipment is thus slimmer and, of course, the device as a whole easier. Since the operator can move with the device almost unrestricted, so it can rise to the top, can also be high-lying, accessible by a person wall areas be cleaned relatively easily. So far water towers have been difficult to clean, as to pump the cleaning medium (the treatment solution) from the bottom in the upper area lying in the tank powerful pumps were needed, which could provide the need to overcome the height difference pressures.
- the cleaning medium the treatment solution
- the mobile sprayer according to the invention works much more efficient and economical than the conventional devices. Since the pump does not have to be constantly driven at its upper power limit to build up the required pressure or to provide the required spray performance, also reduces the wear, and the life or operating life of the pump increases.
- the selected liquid pump (provider: KNF Flotos AG) with an aqueous medium for drinking water tank cleaning and / or disinfection problem a pressure of 1 - 15 bar (low pressure range) and a capacity of 1 - 25 l / min promotes.
- the pump is powered by a low-DC voltage, which can be supplied by accumulators.
- the device is portable or can be pulled on wheels and thereby always be placed in the immediate vicinity of the surfaces to be treated.
