Embodiment Construction

[0049] Such as figure 1 With the vertical mixer shown, the drive 1 is fastened above the bottom 2 of the tank, for example on a bridge 3 spanning the sedimentation tank (details not shown). The pool bottom 2 extends horizontally. The driving shaft 4 extends vertically from the driver 1 , and the hyperboloid mixer body 5 is installed at the E1 end of the driving shaft 4 . Between the pool bottom 2 and the hyperboloid mixer body 5 an annular duct 6 is provided for supplying air to the area below the hyperboloid mixer body 5 .

[0050] Especially as figure 2 As clearly shown, the shaft portion 7 extends from the bottom of the hyperboloid mixer body 5 in the direction towards the tank bottom 2 . The free end E2 of the shaft portion 7 is held in a fixture, generally designated by the reference numeral 8 .

[0051] image 3 and Figure 4 The fixing device 8 is shown in detail. The fixing device 8 has a substantially horizontally extending receiving portion 9 from which two s...

Abstract

The invention relates to a vertical agitator for wastewater and the like received in a sedimentation tank, wherein an agitator tool (5) is mounted on a drive shaft (4) extending vertically from a drive (1) mounted above a tank floor (2), wherein a free end (E2) of a shaft section (7) extending from the agitator tool (5) in the direction of the tank floor (2) is held in a safety bearing (14), wherein the safety bearing (14) is held in a retaining device (8) supported on the tank floor (2), wherein the retaining device (8) comprises a receiving section (9) for a receiving device (12) receiving the safety bearing (14). In order to simplify installation, the invention proposes that the receiving section (9) comprises a recess (11) opening in a substantially horizontal direction for laterally inserting the shaft section (7).

Description

technical field [0001] The invention relates to a vertical mixer according to the preamble of claim 1 . Background technique [0002] Such stand mixers are known, see eg WO03 / 095081. In known vertical mixers, the drive is mounted on a tower-like frame above the bottom of the tank. A drive shaft extends vertically from the driver and is connected to a hyperbolic stirring tool. From the stirring tool bottom, a shaft portion extends in the direction of the tank bottom, the free end of which shaft portion is housed in a safety bearing. The safety bearing is held in a fixture supported on the pool floor. The fixing device is an integral part of the tower frame. Receiving means are provided for receiving the safety bearing and typically include a sleeve mounted on a plate. Said sleeve surrounds the safety bearing and is fastened to the fixture by means of the plate. [0003] With known stand mixers, the holding device is an integral part of a complex tower-like frame. This ...
