Device for Mixing at Least Two Fluid Components, Rotary-Driven Mixer Insert Therefor, and System of the Two

Abstract

The invention relates to a mixer insert having a support rod element and at least one vortexing element and a rotary drive connection structure, wherein the mixer insert, for insertion into a tubular passage element, and together therewith, is adapted to a device for mixing at least two fluid components to be placeable by means of the rotary-drive connection structure in drive connection with a driveshaft of the device, when the mixer insert is inserted into the passage element and the passage element is placed in fluid-tight flow connection with at least two component feed lines of the device, characterized in that the rotary-drive connection structure has a bore hole having a bore hole wall which are adapted to a thread on the driveshaft in such a manner that the bore hole, for producing the drive connection, can be screwed onto the thread, wherein the bore hole wall is shaped by the thread. The invention also relates to such a device for mixing and also to a system of such a device and such a mixer insert.

1 .

         2 . A device for mixing at least two fluid components with at least two component feed lines and a rotary-drive with a driveshaft, wherein the device is adapted to place a tubular passage element in a fluid-tight connection with the component feed lines, and by means of a rotary-drive connection structure of a mixer insert, which has one support rod element and at least one vortexing element and which is adapted for insertion in the passage element, for placement with the mixer insert into a rotary-drive connection, when the mixer insert is inserted into the passage element and the passage element is placed in flow connection with the component feed lines, characterized in that the driveshaft has a thread, which is adapted to the rotary-drive connecting structure in the form of a borehole with a wall, such that the thread can be screwed into the borehole for producing the driving connection, wherein the borehole wall is shaped by the thread. 
     
     
         3 . The system of the device and the mixer insert according to one or both of the preceding claims. 
     
     
         4 . The device according to  claim 1  or the mixer insert according to  claim 2  or the system according to  claim 3 , characterized in that the thread is conical. 
     
     
         5 . The device according to one of the preceding claims, characterized in that the thread is adapted for pushing into, imprinting and/or impressing the borehole wall. 
     
     
         6 . The mixer insert according to one of the preceding claims, characterized in that the support rod element is longitudinal and/or straight at and/or that several vortexing elements are disposed around the support rod element. 
     
     
         7 . The mixer insert according to  claim 6 , characterized in that the support rod element is elongated and that the driveshaft is adapted to drive the mixer insert rotationally around an axis of rotation, which extends in the longitudinal direction of the support rod element and/or in the longitudinal direction of the support rod element in the support rod element. 
     
     
         8 . The mixer insert according to one of the preceding claims, characterized in that at least one of the vortexing elements is a fluid guide vane, which is aligned so as to guide the fluid spirally around the support rod element. 
     
     
         9 . The mixer insert according to  claim 8 , characterized in that, in the axial direction of the support rod element at a section without guide vanes, two sections with at least one guide vane each adjoin, which are aligned for guiding fluid spirally in mutually opposite directions around the support rod element. 
     
     
         10 . The mixer insert according to  claim 8  or  9 , characterized in that, in the axial direction of the support rod element, two sections with at least one guide vane each adjoin one another directly and are aligned for guiding fluid spirally in mutually opposite directions around the support rod element.
