Rotary Electric Electrostatic Powder Container Mixer Adopting Multiple Blades

1.1.1.3 Lifting and tilting

There are two lifting arms located on both sides of mixing head to lift or drop the

container. This lifting and clamping is realized by mechanical. So it’s more durable

and reliable than pneumatic.

Tilting operation is realized by worm and worm wheel structure. And this structure

is driven by ABB or Siemens brake motor. So the tilting is more stable and safe.

After mixing is finished, the container will be tilted backward from the initial upright

position. So the material can be slide down to center from piled at one side.

Meantime, the mixing tool will run idle to shake off the powder on it.

Then the container will be lowered from the mixing head. The exhaust air cylinder

will open and the dust will be vented through the vacuum system.

Compressed air consumption: 0.01m3/min.@6bar.

Lifting &Tilting are carried out by pneumatical cylinders

 1.1.1.4 Frame

Most mixer components are put on the frame.

The frame is made by carbon steel with Zinc plated.

1.1.2.5 Output butterfly valve is made by SS321.

1.1.3 Electrical system

Electrical system contains two parts: the separate electrical control cabinet and the

junction box on the mixer.

1.1.3.1 Mixing process can be controlled by PLC automatically or by manual.

1.1.3.2 All the process is interlocked. The process only can be realized step by step.

1.1.3.3 IP55 electrical control cabinet, RAL7032.

1.1.3.4 Schneider electrical components.

1.1.3.5  Mitsubishi brand PLC and touch screen can control and monitor the process

synchronistically.

1.1.3.6 Isolation voltage transformer is installed on the control circuit.

1.1.3.7 One main switch with extended rotary handle and one emergency stop are located

on the cabinet door.

1.1.3.8 Ventilator with filter is located on both side plates of cabinet. And the forced

ventilation will be realized by axial fan.

1.1.3.9 One alarm located on the top of cabinet will work when faults happen.

1.1.3.10 Omron photoelectric switch can measure each action exactly.

1.1.3.11 Schneider high precision electrical overload relay for tilting motor and lifting

motors can be set in optimized values as request.

1.1.3.12 Double protection on extreme position of tilting and lifting can provide safe and

reliable running of mixer.

1.1.3.13 Safety enclosure is provided with mixer. Only when the door of enclosure closes,

the mixer can be operated.

1.1.3.14 Junction box installed with gland wiring.

1.1.3.15 Safety limit switches installed.

1.1.3.16 Default power supply is 3phase/380V/50Hz for motor and single phase/220V/50Hz for control .
