Ⅵ, Performance description of equipment Mechanism

1.Feeder system

Screw pump uses frequency conversion speed regulation, effectively control the feed volume, and the air temperature interlock.

2. Dielectric circulation system

It consists of blower, inducer, air butterfly valve, air pipe, etc..

The air volume, pressure and wind speed matching of the system is the key, according to many years' experience, it is now mature..

3. Air heating purification system

It consists of primary air filter, high efficiency air filter, fan, etc.

The heat source is gas stove

4. Drying tower system

By drying main tower, hot air distributor, atomizer, observation manhole, tower lighting, pneumatic hammer, etc.

This system is the core system.

(1) Combined with experimental experience, we are involved in the design of the main tower:

1,The spray distance of atomizer is calculated strictly, and the diameter of the main tower is enlarged reasonably to prevent the material from sticking to the wall during the pre-drying process.

2,A reasonable ratio of height to diameter of the straight cylinder of the main tower is designed to ensure the sufficient residence time of the material and the effect of spray drying.

3,The taper angle of the cone of the tower is adjusted to 55 °, and the smooth flow of the material in the cone is fully considered..

(2) The atomizer adopts frequency converter to adjust the speed of atomizer to achieve the best atomization effect. By lowering the atomizer base and increasing the distance between the atomizer tray and the top of the tower, the atomizing liquid droplets cannot return to the top under the spinning of the wind, so as to ensure the normal operation of the system.With high speed motor drive, the spindle speeds up to 15000 ~ 16000R.P.M,through the gear box, making the atomizer line speed up to 130m/min, ensuring atomization effect. With the digital automatic detection device for oil pressure, the main shaft is equipped with water-cooled oil cooling device to ensure that the spindle is not affected by high temperature. According to the requirements of finished products, the orifice, square hole or rhombus hole can be used for the hole shape of the atomizer.

(3) Pneumatic hammers, which adopt new products of Japanese refreshing technology, can ensure the effect of vibration, reduce the noise of knocking products, and make the distribution reasonable.

(4) Design the multi - set of lighting devices in the tower and three observation and cleaning doors , manhole

(5)The wind turbine shell of the main tower adopts an accelerating structure, so that the hot air can effectively press the material into the tower, and the orderly vortex decreases. And the hot air distributor also combines the characteristics and requirements of the technology, and the air guide mechanism on both sides of the distributor can be achieved, and the angle can be adjusted at any time to control the tangential angle of the hot air inlet.

5. Collecting system

The charging system of the spray drying unit is composed of a cyclone separator. The cyclone is collected by a high efficiency and high efficiency two stage cyclone, and the powder collecting rate can reach 99%..

6. Other auxiliary systems

All are supplied by well-known manufacturers, reliable performance; part of the pipeline considered a certain angle design, the use of pressed smooth stainless steel pipe, to avoid material closure, plugging, and local resistance to affect the material transport phenomenon.

7.Control system

Centralized control of control cabinet, all electrical components are well-known brands in China.
