Mixing principle

The low-speed stirring paddle and the serrated dispersing disc installed on the high-speed dispersing 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).

C. Diameter of dispersion plate: Φ55mm.

Lifting (mixing barrel)

A.Hydraulic lifting: piston cylinder Φ63/D40×S270; equipped with double guide rods, positioning device; positioning is safe and reliable.

B.One set of hydraulic oil pump station, equipped with a 0.37Kw/4P motor; no oil leakage, low noise.

C.Lifting height: ≤270.

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.Keep the pressure for 24 hours, and no oil leaks into the mixing bucket under the mixing or pressure maintaining state.

GPS

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 precisely matched with the mixing barrel to ensure that the position of the mixing barrel is reasonable and the positioning is accurate.

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 (ie without PLC and touch screen) does not include this item).

B.Man-machine interface operation function: This is an optional item, and the customer needs to purchase it at an additional price if necessary, and the plan will be quoted separately.

Safety 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.Utilize circuit design such as proximity switch 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.Door bolt-type buckles are set on the kettle cover and the mixing barrel to prevent the oil cylinder from falling automatically.

Temperature measurement method

0-300℃, the temperature probe is located on the wall (or bottom) near the bottom of the barrel, which is in contact with the material and displays the temperature.

Total power of host: 3.7KW+ power of lifting motor: 0.37kw

Working voltage/frequency: 380V/50Hz/3Phase; control voltage: 220→24V.

Sealing material

Static sealing: use silicone rubber/fluorine rubber/NBR "O" or "trapezoidal" sealing ring, depending on the working conditions.

Dynamic seal: SiC-C+fluorine rubber.

High-speed bearing

The dispersing shaft and a high-speed intermediate drive shaft adopt German FAG or Japanese NSK brand.

Dispersion effect

The decentralized transmission adopts high-quality synchronous belts, so that the decentralized shaft does not lose rotation, and the decentralized shearing effect is good.
