Abstract: The device for producing fuel and/or heating fuel from oil- and/or fat containing wastes in vehicles and/or transport means, comprises a double-walled collector filled with the oil- and/or the fat containing wastes, a heat source for the wastes, and a pump that presses and/or sucks the wastes by a filter present in filter housing. An inflow- and return flow line of the heat source and a tank line is closed and opened at the exit of the filter by shut-off valves and/or valves. Fast connections with and without valve are used for the connection at the vehicle and/or the transport means. The device for producing fuel and/or heating fuel from oil- and/or fat containing wastes in vehicles and/or transport means, comprises a double-walled collector filled with the oil- and/or the fat containing wastes, a heat source for the wastes, and a pump that presses and/or sucks the wastes by a filter present in filter housing. An inflow- and return flow line of the heat source and a tank line is closed and opened at the exit of the filter by shut-off valves and/or valves. Fast connections with and without valve are used for the connection at the vehicle and/or the transport means. The filter is protected by a safety valve, which reduces the supply of filter in reaching the maximum operating pressure of the filter and which leads the oil and/or fat containing wastes back into the pressure-free collector. An additional water pump assists the water circulation of the heated water. A fuel acoustic radiation system is present in the collector or at other lines transferring the wastes and improves the combustion characteristics of the wastes through reduction of the surfaces tensions. A return pipe for the collector leads the not yet filtered fuel and/or heating fuel with large particles back into the collector. The first liters, passed and filled to the filter, contain first larger particles, because the filter needs a certain starting time until an optimal degree of purity is achieved. The filtered-out particles provides for a finer filtration for the large particles. Temperature sensors serve for sensing the collector contents, the filter and the pump. The collector possesses an exhaust, in order to ensure the return flow of the safety valve. The degree of purity of the fuel and/or heating fuel is examined through liquid sensors as photosensors, and the tank is released by magnetic valve and/or a collecting tank filled with the fuel and/or heating fuel. Different magnetic valves control the flow of the fuel and/or heating fuel, the return pipe and the water circulation. Different level indicators enable an inspection of the states of the contents of the collector and of the collecting tank. The filling of the fuel- and/or the heating material is fully automatically controlled through the magnetic valves and the level indicators. An additional temperature sensor present at the heat source or their inlets for control and security of the device and for the protection of the environment, a liquid sensor for control of the density and a photosensor for examining the light permeability of medium, are intended. The heated and/or not-heated pre-filtration of the wastes reduces the contamination of the fuel materials. The pre-filtration consists of a further collecting tank with filter bag, which has a heating coil as heat source, which is filled with hot cooling water and which wraps around the filter bag. Cameras and optical monitors serve for monitoring the full operability and security of the device. Switch-on- and switch-off mechanisms are intended, with which the current supply is activated or interrupted to the pump at any time. Laptop and personal computer are indented, which indicate the measured values of the used sensors, drive the process of the filtration in fully automatic manner and acoustically indicates the parameters important for the user. The level indicator informs about the already produced quantity of the fuels. An adjustable aeration valve protects the collector and/or pump, in which a pressure balance/- reduction takes place before reaching the maximum operating pressure. The collector as filter housing of a pump at the tank line assists the filter procedure by sucking procedure. The oil of an oil mill is filtered with very small degree of purity and the large particles negatively affect the combustion in diesel engines and lead to a blockage of the injection nozzles.
