A resistant sealing between the mounting frame and the concrete surface is ensured
only if the surfaces surrounding the installation plate are polished and even.
Danger of explosion due to biogas emissions!
To ensure the mixer frame sealing, the tank cover has to be even enough, i.e. it has
not to have hollows or unevenness!
Check the correct grounding connection of the mixer!
6.1.2 Mixer with wall mounting
To install the mixer, make a hole of 1300 x 1300 mm in the wall.
It has to be installed at a such height, so that the distance between the upper corner of the
wall opening and the higher corner of the tank wall is 0,5m.
Usually we recommend to place the mixer at least 4-5m far from the raw material input area,
so that the propeller radius of action could generate an uniform homogenization of the solid
matters introduced.
The mixer position has to fit any other mixers already present.
The mixer thurst effect has not to be altered.
The standard provided mounting frame has a 30° tilt to the left, in order that the flow of the
mixed product turns in a clockwise direction.
Normally the vortex generated by the mixing vanes makes the rotary motion of the mixed
product easier.
During the design and the carrying out of the hole in the wall, take into account that
from the external side of the tank there has to be room enough for the manoeuvres
necessary for mixer installation and dismantling.
Furthermore take into account the suitable distance between other possible tanks or
equipments.
A resistant sealing between the mounting frame and the concrete surface is ensured
only if the surfaces surrounding the installation plate are polished and even.
Remove the insulating material situated on the tank outside side (if present).
In case of unevenness around the tank hole, remove it.
Remove or repair any tank wall defects, which could come out of its dismantling,
according to the laws in force concerning building.
An incorrect fixing of the mixer and the consequent vibrations due to mixing could both
damage the mixer and cause the leak of fermented substrate as well as environmental
damages.
Therefore, in case of doubts, we suggest that an expert should check possible faults to
be improved. All that carried out has to documented and attached with photos.
