1-10 Vacuum system

1. Equipped with a vacuum liquid buffer tank and a ball valve switch; the bottom of the buffer tank is provided with a drain port, and the buffer tank and the vacuum pump are connected with a metal hose;

2. Dynamic seal: mechanical seal ( GB-103 type ) is adopted; static seal: FPM material "O" ring is adopted in high temperature parts , and NBR material "O" ring is adopted in low temperature parts;

3. The equipment can be operated under vacuum during the stirring and mixing process, and the vacuum degree is ≤-0.098Mpa ;

4. The upper barrel is equipped with a vacuum pressure display gauge. The vacuum pipe interface is a G3/8 ball valve, and a vacuum buffer device is installed on the column.

1-11 Electrical control system

Push-button control operation

Low voltage electrical components: Chint;

Inverter: Contemporary Controls;

4. Induction switch: German Schneider or Japanese Omron;

1-12 Temperature measurement method

1. A metal thermocouple

2. The temperature range of the material is 0-200 degrees;

3. The temperature sensor is located at the bottom of the barrel, directly in contact with the material, the temperature is more accurate, and the temperature measurement error is ± 1 degree;

1-13 Appearance requirements

1. Comply with JBIT7669-2004 plastic mixing standard.

2. The paint should be even, smooth, consistent in color and glossy; the paint surface should be transparent, non-sticky, strong in adhesion, and elastic, without wrinkles, peeling, paint leakage, flow marks, bubbles, etc. It should also comply with the technical conditions of HG/T3228-2001.

1-14 Safety System

1. Relying on the frequency converter and limit travel switch, through a specially designed control route, the barrel is ensured to stop automatically after it reaches the specified position;

2. During the rising 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;
