Tank cleaning device and method

A method for operating a tank cleaning device, the method comprises the steps of:

• providing a tank cleaning device having a tank cleaner having a plurality of tank cleaner components including a drive means comprising a drive means component, a nozzle holder rotatable about two axes and at least one nozzle arranged on the nozzle holder, wherein at least one of the tank cleaner components is designed as a replaceable element, a type of replaceable element is defined by the tank cleaner component designed as the replaceable element, that a first portion of the tank cleaner forms a replaceable element holder being configured to hold a corresponding replaceable element;
• selecting a replaceable element from a first group of replaceable elements of a first type;
• replacing a replaceable element of the first type which is mounted in the tank cleaner of the tank cleaning device with the selected replaceable element of the first type in order to adjust a parameter of the tank cleaner that influences cleaning performance;
• selecting a replaceable element from a second group of replaceable elements of a second type;
• and,
• replacing a replaceable element of the second type which is mounted in the tank cleaner of the tank cleaning device with the selected replaceable element of the second type in order to adjust a parameter of the tank cleaner that influences the cleaning performance,
• wherein the parameter of the tank cleaner adjusted by replacement of the replaceable element of the first type and the parameter of the tank cleaner adjusted by the replacement of the replaceable element of the second type are selected from the following group of parameters:
• i) number of cleaning jets, (ii) rotational speed, (iii) jet width, in order to adjust at least two parameters of the group of parameters.

A method for producing a modular tank cleaner in which cleaning fluid is dispensed into a tank from a nozzle installed on a nozzle holder of said tank cleaner, which nozzle holder is made to rotate by a drive means that has a drive means component, said method comprises the steps of:

• configuring a first portion of the tank cleaner to form a first replaceable element holder and a second portion of the tank cleaner to form a second replaceable element holder,
• configuring the drive means or the drive means component as a replaceable element which can be accommodated in the first replaceable element holder and by which a first type of replaceable element is defined, wherein the first replaceable element holder is configured to hold the first type of replaceable element,
• configuring one of the nozzle holder and the nozzle as a replaceable element which can be accommodated in the second replaceable element holder and by which a second type of replaceable element is defined, wherein the second replaceable element holder is configured to hold the second type of replaceable element,
• providing a first group comprising a plurality of replaceable elements of the first type allowing parameters that change cleaning performance to be adjusted in a targeted manner, and
• providing a second group comprising a plurality of replaceable elements of the second type allowing parameters that change the cleaning performance to be adjusted in a targeted manner,
• wherein the parameters that change the cleaning performance are selected from the following group:
• number of cleaning jets, rotational speed, jet width.
