Definitions

the invention relates to a static mixing device for fluids containing or consisting of solid particles according to the preamble of claim 1.
Such cases occur, for example, in municipal wastewater treatment, e.g. when mixing chemicals in sludge, in the paper industry or also in the food industry, e.g. when mixing fruit pieces in yogurt.
a mixing device is also known from US-A-3733057, the mixing device consisting of a tubular housing with at least one mixing element arranged therein, which has two or more webs inclined with respect to the longitudinal axis of the housing, the outer contour of the webs being adapted to the housing wall .
This mixing device is essentially a mixer of the so-called "KENICS-NISCHER-TYPE", but there is a through channel in the center.
the invention is based, for media of the type mentioned above, i. even fluids consisting of piece goods or containing piece goods to create a blockage-free, static mixing device which also ensures homogeneous mixing with an acceptable pressure loss.
the design according to the invention of a static mixing device prevents the settling or catching of solid particles between the webs and casing wall or between crossing webs with simple means, so that a perfect mixing can be carried out in the device.
the outer webs or the one ends of the inner webs can be welded or soldered to the tube wall, for example.
the device cross section can be both circular and have a different contour, e.g. be a rectangle.
the web cross sections can taper towards the free ends.
the cross sections and the longitudinal section shapes advantageously have aerodynamic contours, e.g. rectangular, elliptical or semicircular.
the angle between the webs and the tube axis is advantageously in the range from 30 to 60 °, in particular 45 and 30 °.
mixing elements are arranged in a mixing device, an advantageous development of the invention can consist in that the successive ones.
Mixing elements are each arranged at an angle, in particular offset by 90 °, in the housing. This ensures spatial homogeneity.
Another application can e.g. consist of mixing flocculation chemicals in secondary sewage sludge in front of a centrifugal decanter of a municipal sewage treatment plant for sludge dewatering.
the installation of a mixer according to the invention takes into account the requirement for an efficient use of the quantity of chemicals for rapid and uniform mixing.
each mixing element pivoted relative to one another by 90 ° are arranged in a casing tube 1.
each mixing element consists of three webs 2a to 2c, with a space remaining between the crossing webs, as can be clearly seen from FIGS. 2a to 2d.
FIGS. 1 to 2d is a particularly advantageous embodiment, it is in principle also possible, depending on the process in which the mixing device is to be used, to design the mixing device with a plurality of webs. 3 and 4, a mixing element is shown, which is arranged in a tube 3 and which consists of two outer webs 4a and 4c and inner webs 4b, 4d and 4e.
