Definitions
- the invention relates to a housing for micromixers with two flat housing parts lying against one another in a parting plane and to the connecting elements connecting the two housing parts.
- Micromixers for mixing liquid, viscous or gaseous phases are known in different embodiments.
- the mixer housing has two flat housing parts which are pressed against one another in a sealing manner with their connection surfaces facing one another.
- For the tight connection of such mixer housing parts it is known to use several clamping screws distributed around the circumference, which are inserted through fastening bores of one housing part and screwed into threaded bores of the other housing part or also inserted through screw bores there and provided with nuts on the rear side of the housing. This requires a relatively high manufacturing cost. In particular, the time and effort required for the frequently required disassembly and assembly of the housing parts is relatively high.
- the object of the invention is therefore to design a housing for micromixers of the type mentioned at the outset in such a way that it can be produced in a simple manner and can be opened and closed in a simple manner with little effort and time.
- the two housing parts are designed substantially in the shape of a circular disk and have a truncated cone surface on their peripheral edge facing away from the parting plane and in that a multi-part clamping ring which can be tensioned in the circumferential direction has the edges of the two
- the two truncated cone surfaces form broad, flat bevels on the outer peripheral edges of the housing parts;
- the clamping ring which is pressed radially against this truncated cone surface from all sides, causes the two housing parts to be pressed uniformly against one another in order to achieve the tight seal in the parting plane. To dismantle it is sufficient to loosen the clamping ring and take the two housing parts apart. Conversely, assembly is just as simple; the two housing parts are placed on top of each other, and the clamping ring is put around and tightened.
- the exact mutual assignment of the two housing parts can be achieved by centering.
- the two housing parts are preferably centered on one another by at least one centering pin.
- the clamping ring has two substantially semicircular ring segments which are connected to one another at at least one of their two connecting points by a clamping element.
- the clamping element can be a screw connecting the two ring segments in the circumferential direction.
- the two ring segments are preferably connected to one another in an articulated manner at the connection point opposite the clamping element. This means that only a single clamping element is required for the clamping process.
- Fig. 1 shows a vertical section through a housing for a
- FIG. 1st is a plan view of the housing of FIG. 1st
- Channels are accessible after separating the housing parts 1 and 2 in the parting plane 3, for example for a cleaning process.
- the two flat housing parts 1 and 2 are designed as circular disks and each have a flat truncated cone surface 4 or 5 on their peripheral edges facing away from the common parting plane.
- a multi-part clamping ring 6 is placed from the outside around the assembled housing parts 1 and 2. It consists of two ring segments 6a and 6b, which are essentially semicircular. In cross section, the two ring segments 6a and 6b are U-shaped and rest with inner truncated cone surfaces 7 and 8 on the truncated cone surfaces 4 and 5 of the two housing parts 1 and 2.
- the two ring segments 6a and 6b are connected to one another at their one connection point located at the top in FIG. 2 by a screw 9 which carries a wing nut 10.
- the two ring segments 6a and 6b are articulated by a link member 11 which is mounted on the two ring segments 6a and 6b.
- Two centering pins 12, of which only one centering pin 12 is shown in the drawing, are inserted into one housing part 2 and protrude into a matching centering groove 13 of the other housing part 1 in order to center the two housing parts 1 and 2 against one another.
- the two ring segments 6a and 6b of the clamping ring 6 are contracted in the circumferential direction so that they press the two housing parts 1 and 2 against one another at high pressure under the wedge action on the flat truncated cone surfaces, so that a tight seal Connection is guaranteed.
- two metal capillaries 14 are soldered to the upper housing part 1 in the exemplary embodiment shown, the other end being unsoldered with a commercially available one Screw connection are provided.
- Another line 15 is fastened directly to the housing part 1 by means of a conventional threaded screw connection 16.
