Embodiment Construction

[0027] figure 1 A schematic diagram of the fixing device 1 of the present invention is shown, which fixes a pair of duct ventilators 2 for sewage purification in a central duct 3 so that air can be supplied from the central duct 3 to each duct ventilator 2 . The schematic diagram illustrates that the fixing device 1 of the invention is constructed as a pipe saddle which can be closed around the circumference of the central pipe 3 and has a plurality of hinged housings 11 . The housings 11 are produced with only one, in particular the same injection moulding mould, and have exactly the same shape. Each housing 11 has a substantially arcuate support portion which can bear on a circumferential surface 31 of the central duct 3 and span an arc length of about 180°. An air supply portion 12 extends substantially radially outwardly with respect to the axis of curvature of the arcuate support portion. Air can be supplied from the central duct 3 to the duct ventilator 2 through the a...

Abstract

The invention relates to a fixing device (1) for pipe aerators (2) for waste water purification, for fixing at least one pipe aerator (2) to a central pipe (3) in such a way that air from the central pipe (3) is supplied to the pipe aerator (2). The aim of the invention is to provide a fixing device for pipe aerators (1) for waste water purification, that is easy to assemble. According to the invention, the fixing device (1) is embodied as a pipe hanger that can be closed around the periphery of the central pipe (3) and comprises shells (11) connected in an articulated manner. At least one of the shells (11) has an air supply section (12) via which air from the central pipe (3) can be supplied to the pipe aerator (2).

Description

technical field [0001] The invention relates to a fixing device for a duct ventilator for sewage purification in order to fix at least one duct ventilator on a central duct so that air can be supplied to the duct ventilator from the central duct. Background technique [0002] Such fixtures are known. In a conventional solution, two duct ventilators extending perpendicular to a central duct in opposite installation directions are fixed to each other via a screw. Such fixtures are inconvenient to install, require long installation times and require two people to install a pair of ducted ventilators. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a convenient fixing device for the installation of a duct fan for sewage purification, so as to fix at least one duct fan on a central duct, so that air can be supplied from the central duct to the duct fan. [0004] In order to achieve the object of the present invention, a fixing device for a...
