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).

1-8-3 Dispersing shaft and disc

A. Material: SUS304; C. Diameter of dispersion plate: Φ55mm;

B. One, a dispersion plate is installed on the 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.

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.
