Embodiment Construction

[0034] figure 1 A longitudinal section of an embodiment of a static spray mixer according to the invention indicated as a whole by reference numeral 1 is shown. For better understanding, figure 2 A perspective view of this embodiment is shown. The spray mixer is used for mixing and spraying at least two flowable components.

[0035] Reference is made below in particular to the case involving the practice of mixing and spraying exactly two components. However, it should be understood that the invention can also be used for mixing and spraying more than two components.

[0036] The spray mixer 1 comprises a tubular integral mixer housing 2 extending in the direction of the longitudinal axis A to a distal end 21 . In this respect, at the end indicated by the distal end 21 the mixed components are discharged from the mixer housing 2 in the operative state. To this end, the distal end 21 has an outlet opening 22 . The mixer housing 2 has a connection piece 23 at the proximal...

Abstract

The present invention relates to static spray mixers, and in particular proposes a static spray mixer for mixing and spraying at least two flowable components, the static spray mixer having a direction extending in the direction of the longitudinal axis (A) to having A tubular integral mixer housing (2) at the distal end (21) of the outlet opening (22) for the components, having at least one arranged in the mixer housing (2) for mixing the components The mixing element (3) has an atomizing bush (4) with an inner surface surrounding the mixer housing (2) in its end region, wherein the atomizing bush ( 4) Has an inlet (41) for the pressurized atomizing medium. A plurality of grooves are provided in the outer surface of the mixer housing (2), or in the inner surface of the atomizing bushing (4), respectively extending in the direction of the longitudinal axis (A), and Through the plurality of grooves, the atomizing medium can flow from the inlet (41) of the atomizing bush (4) to the distal end (21) of the mixer housing (2).

Description

technical field [0001] According to the preambles of the independent claims, the invention relates to a static spray mixer for mixing and spraying at least two flowable components. Background technique [0002] Static mixers for mixing at least two flowable components are described, for example, in EP-A-0 749 776 and EP-A-0 815 929 . Despite the simple, material-saving design of the mixer construction of these mixers, these very compact mixers provide good mixing results, especially with high-viscosity materials such as sealants, two-component foams or The same applies to the mixing aspects of two-component adhesives). Such static mixers are generally designed for a single use and are frequently used for products to be hardened, in which the mixer can hardly be cleaned anymore. [0003] In some applications using such static mixers, it is desirable to spray the two components onto the substrate after mixing the two components in the static mixer. For this purpose, the mix...
