Problems solved by technology
However, the problem arises with known mixing devices that, even with very efficient mixing blocks and mixing tubes, a sufficiently homogeneous mix concentration cannot be obtained or only sufficient outlay on suitable control and design. Homogeneous Mixed Concentration
In the case of a reduced channel cross-section, in which the setting of the hydraulic pressure of the feed component is advantageously kept constant, a smaller amount of the feed component is available in the following timed cycle, with the result that the feed amount is controlled part determined that the target feed volume value was not reached until later, which caused the required extension of the feed interval

Embodiment Construction
[0042] Figure 1 to 3 Three different preferred embodiments of the mixing device according to the invention, which are similar in structure to each other, are generally indicated with the reference number 1. In order to improve the readability of the drawing description, the same reference numerals for the same or similar components are used for the three different embodiments.
[0043] In the representative case, the mixing device 1 is used in a two-component mixing system in which the parent component A and the feed component B are processed. The parent component A can be a parent paint, while the feed component B is a hardener.
[0044] A single holding tank 3, 5 is stored for both parent component A and feed component B. The piston pump 11 for the parent component A and the piston pump 13 for feeding the component B take the corresponding components A and B from the storage tanks 3 and 5 and generate hydraulic pressure in the components A and B, It is intended to create a pre...

The present invention discloses a method for mixing (in particular) at least two liquid components of a two- or multi-component wet coating system, wherein the feed group at a (in particular) constant hydraulic pressure is fed discontinuously through a variable passage section to the parent component at a (specifically) constant hydraulic pressure, the actual feed amount of the feed component is detected and compared to the The target feed amount of the feed component adjusts the feed amount of the feed component in such a way that the timed cycle of the discontinuous feed and the channel cross-section of the feed component are affected .
Description
Technical field [0001] The present invention relates to a method and device for mixing at least two liquid components. Specifically, the subject of the present invention is a method and device for mixing at least two liquid components in a two- or multi-component wet coating system and a two- or multi-component wet coating system. Component mixer. This method is used, for example, in a two-component painting system in a wet zone, where hydraulic conditions are established with a delivery pressure of the liquid component of, for example, 50 to 530 bar, preferably 160 to 180 bar. At least two liquid components are gathered together in a common flow and then mixed in the mixing block so that the component mixture can then finally be atomized at the nozzle (e.g., air gun). Such systems are used, for example, in automotive engineering for coating large area components (e.g., steel beams) or small area components (e.g., plastic components). The coating should be formed from a mixtu...
