|
1-5 mixing principle
|
The low-speed stirring paddle and the serrated
dispersing disc installed on the high-speed dispersion shaft both rotate and
revolve; at the same time, combined with the low-gap design of the stirring
paddle, the low-speed stirring paddle makes the material produce strong
kneading interference motion and up-down/left-right circulation. ; The
high-speed dispersing disc strongly shears and breaks up the materials; thus
finally ensuring that the materials are fully dispersed and evenly blended
(mixed).

dispersion shaft to ensure better dispersion/mixing.
|
1-9 lifting (mixing barrel)
|
A. Hydraulic lifting: piston cylinder Φ63/D40×S270;
equipped with double guide rods, positioning device; safe and reliable
positioning.
B. One set of hydraulic oil pump station,
equipped with a 0.37Kw/4P motor; no oil leakage, low noise.
C. Lifting height: ≤270.
|
1-10 vacuum system
|
A. The stirring and dispersing process can be
carried out under vacuum; vacuum degree: ≤-0.098mPa.
|
B. Equipped with vacuum pump 2XZ-2.
|
C. With vacuum buffer tank and switch.
|
D. Dynamic seal: mechanical seal; static seal:
O-ring seal.
|
E. Maintain the pressure for 24 hours, and no
oil leaks into the slurry tank in the state of mixing or maintaining
pressure.
|
1-11 positioning system
|
A. With positioning adjustment device and
locking device, it can accurately position the mixing barrel and the upper
barrel and prevent rotation.
B. The positioning stop of the lower flange of
the upper barrel body is matched with the mixing barrel to ensure that the
position of the mixing barrel is reasonable and the positioning is accurate.
|
1-12 control system
(Manual operation control)
|
A. Manual operation control function: The
vacuum start/stop during equipment operation, frequency conversion speed
regulation, temperature display (or temperature control), spotlight switch,
lift, and emergency stop operation are all performed on the operation panel.
Remarks: Dispersion has a timing function
(recommended, but normal manual operation (that is, without PLC and touch
screen) does not include this item).
|
B. Man-machine interface operation function:
This is an optional item, customers need to purchase at an additional price
if necessary, and the plan will be quoted separately.
|
1-13 Safe operation
|
A. Relying on the frequency converter and the
limit travel switch, through the specially designed control route, it is
guaranteed that the barrel will stop automatically when it reaches the
specified position.
|
B. During the ascending process of the barrel,
the mixing/dispersing part of the equipment cannot be started. Similarly,
when the machine is running the mixture, the barrel cannot be lowered and the
mixing barrel cannot be opened.
|
C. Use circuit design such as proximity
switches to ensure that the mixing tank cannot be lowered under vacuum.
|
D. The special vacuum buffer tank design can
effectively prevent the vacuum pump oil from returning to the mixing tank.
|
E. The door bolt type buckle is set on the
kettle cover and the mixing barrel to prevent the oil cylinder from falling
automatically.
|
1-14 Temperature measurement method
|
0-300℃, the temperature probe is located on the
wall of the barrel (or the bottom of the barrel) near the bottom of the
barrel, contacts the material and displays the temperature.
|
1-15 Total power of main engine: 3.7KW+ power
of lifting motor: 0.37kw
|
Working voltage/frequency: 380V/50Hz/3Phase;
control voltage: 220→24V.
