2. Introduction
2.1. General
The
Inocenter
powder station is a ventilated powder dispensing enclosure allowing:
1 Powder supply to projectors and guns (24 maximum).
2 Automatic cleaning of:
• powder pumps,
• powder supply hoses,
• the inside of projectors and guns,
• powder recycling hose.
• powder tank.
The powder station can operate autonomously.
It is then controlled from the keyboard located on the front of the electro-pneumatic cabinet (
for the
Inomaster Platinum
cabinet). The PLC monitor allows the operator to be guided and to follow his actions in real time.
It indicates to the operator the status of the powder unit (defects, cleaning steps, operations to be carried out).
2.2. Equipment overview
2.2.1. Vibrating table
The table, a 20kg powder box support, is equipped with an electric vibrator to facilitate the flow of the powder during
the pumping phase.
During the cleaning phase, the table, which is mobile, must be moved manually under the tank drain valve in order to
empty it.
Once cleaning is completed, return the table to its initial position.
When you have finished cleaning, return the table to its original position.
2.2.2. Powder transfer pump
This pump, equipped with 4 sleeves, allows the transport of new powder from the box to the fluidized tank.
During the production phase, the operation of the pump is managed by the level sensors of the tank.
The transport capacity of this pump, with a new powder box, is around 300 kg/min.
When starting the installation, it is necessary to force the filling of the tank until the information: "central OK" is
obtained.
2.2.3. Tank
This fluidized tank allows the distribution of powder to the projectors through a set composed of a sleeve valve and
a venturi type pump.
This tank can be equipped with a maximum of 24 pumps. It is equipped with 2 powder level detectors to ensure the
management of the filling and to maintain a constant level during the production phase.
An electric vibrator guarantees a good fluidization for difficult powders.
The tank is connected directly to the ventilation duct via a valve mounted on a pneumatic cylinder. This flap allows
to significantly increase the suction flow when it is open during the cleaning phases.
The tank must be emptied every evening at the end of the shift.
