Mixing element for a static mixer

A mixing element for a static mixer for installation into a tubular mixer housing, comprising:

• a plurality of first and second installation bodies arranged behind one another along a longitudinal axis of the mixing element,
• each of the first and second installation bodies having a first wall element extending in a direction of the longitudinal axis and a first side wall and a second side wall arranged opposite the first side wall;
• a deflection element arranged adjacent to each of the first wall elements, each of the deflection elements having a deflection surface extending in a transverse direction to the first wall element at both sides of a respective first wall element,
• a first opening is disposed in each of the deflection surfaces at a side facing the first side wall of the respective first wall element,
• second and third wall elements arranged adjacent to each of the first openings,
• the second and third wall elements extending in the direction of the longitudinal axis and each having an inner wall and an outer wall extending substantially in the direction of the longitudinal axis and each of the inner walls and outer walls including an angle between 20° and 160° to the first or second side walls of the respective first wall element,
• each of the first openings is arranged between the inner walls of a respective second and third wall elements and a second opening arranged outside one of the outer walls of the respective second or third wall elements,
• the second opening is disposed in a respective deflection surface at a side facing the second side wall of the respective first wall element,
• the first wall element of the second installation body adjoining the second and third wall elements of the first installation body,
• the second installation body arranged rotated about the longitudinal axis by an angle of 180° with respect to the first installation body,
• the first and second installation bodies connected to one another by a common bar element, and
• the first wall element of the second installation body, the deflection surface of the deflection element of the second installation body at the side facing the second side wall of the first wall element of the second installation body, the common bar element and each of the second and third wall elements of the first installation body define a transverse passage of non-rectangular cross-section.
