1、 Working principle:
The wet material is continuously added to the first layer of drying disc on the upper part of the dryer by the feeder. The rake arm with rake blades rotates to continuously flip the material. The material flows along an exponential spiral through the surface of the drying disc. The material on the small drying disc is transferred to the outer edge and falls to the outer edge of the large drying disc below. The material moves inward on the large drying disc and falls into the next layer of small drying disc from the middle dropping port. The large and small drying discs are alternately arranged up and down. The material can continuously flow through the hollow drying disc of the entire dryer and be heated by a heating medium in the form of saturated steam, hot water, and thermal oil. The heating medium enters from one end of the drying disc and is exported from the other end. The dried material falls from the last layer of the drying disc to the bottom of the shell. Finally, it is discharged from the rake blade basket type material outlet Moisture escapes from the material and is discharged through the moisture outlet located on the top cover. The moisture in the vacuum disc dryer is extracted through the air pump located on the top cover. The dry material discharged from the bottom layer can be directly packaged. By adding auxiliary equipment such as fin heaters, solvent recovery condensers, bag filters, dry material mixing mechanisms, and induced draft fans, its drying production capacity can be improved. Dry paste and heat sensitive materials can be easily recovered for solvent recovery

2、 Equipment features:
A) Easy regulation and strong applicability
1. Adjusting the thickness of the material layer, spindle speed, number of rake arms, rake blade type and size can achieve the best drying process
2. Each layer of the drying tray can be individually filled with a hot or cold medium to heat or cool the material. The temperature control of the material is accurate and easy
3. The residence time of materials can be precisely adjusted
4. The material flows in a single direction without any backmixing. The drying is uniform, the quality is stable, and there is no need for further mixing
b) Simple and easy to operate
1. The operation of driving and parking the dryer is very simple
2. After stopping the feeding, the rake blades that transport the material can quickly empty the material in the dryer
3. By using special large inspection doors and mirrors, the equipment can be carefully cleaned and observed inside
c) Low energy consumption
1. The material layer is very thin and the spindle speed is low. The material conveying system requires less power and consumes less electricity
2. Drying is carried out by conducting heat. It has high thermal efficiency and low energy consumption
d) Good operating environment, recyclable solvents. Dust emissions meet requirements
1. Atmospheric pressure type: Due to the low airflow velocity and low humidity distribution inside the equipment, it is difficult for dust to float to the top of the equipment
The exhaust gas discharged from the dehumidification outlet contains almost no dust
2. Sealed type: equipped with a solvent recovery device • can easily recover organic solvents from moist gas. The solvent recovery device is simple, with a high recovery rate, and is suitable for flammable, explosive, toxic, and easily oxidizable materials. Nitrogen can be used as the moist gas for closed-loop circulation, making it safe to operate and particularly suitable for drying flammable, explosive, and toxic materials
3. Vacuum type: a disc dryer operated in a vacuum state, particularly suitable for drying heat sensitive materials
e) Easy installation and small footprint
1. The dryer is shipped as a whole, transported as a whole, and only needs to be lifted into place. Installation and positioning are very easy
2. Due to the layered arrangement and vertical installation of the drying tray, it can result in a large drying area and a small footprint

3、 Technical features:
a) Drying dish
1. Design pressure: generally 0 4 MPa, up to a maximum of 16 MPa
2. Maximum operating pressure: generally ≤ 0.4 MPa, up to 1.6 MPa
3. Heating medium: steam, hot water, heat transfer oil. When the temperature of the drying disc is ≤ 100~C, hot water should be used for heating. When the temperature is around 150 ° C, saturated steam or superheated steam with a pressure of ≤ 0.4 MPa should be used for heating. When the temperature is around 150-C -320%, heat transfer oil should be used for heating. When the temperature is above 320 ° C, methods such as electricity, heat transfer oil, and molten salt can be used for heating.

b) Uranium material conveying system
1. Spindle speed: 1-10 revolutions per minute, electromagnetic or variable frequency stepless speed regulation.
2. Rake arm: There are 2-8 rake arms fixed on the main shaft on each layer of the drying disc
3. Rake blade: Twisted onto the rake arm, it can float up and down with the disc surface to maintain contact, and has various types
4. Rolling: For materials that are prone to clumping and need to be crushed, rolling can be added at appropriate positions to enhance heat transfer and drying processes. There are three types of transparent materials: atmospheric pressure, sealed, and vacuum
1. Atmospheric pressure type: cylindrical or hexagonal prism. There are two types of structures: integral and split. The main pipeline for the inlet and outlet of the heating medium can be located inside or outside the shell.
2. Sealed type: cylindrical shell, capable of withstanding an internal pressure of 5KPa. The main inlet and outlet pipes of the heating medium can be located inside or outside the shell
3. Vacuum type: cylindrical shell, designed with an external pressure of O 1MPa. The main inlet and outlet pipelines of the heating medium are located inside the shell

4、 Operation process and specifications of high-speed dryer:



Basic configuration: continuous drying and storage process based on quantity
Wet materials are evenly added to the top of the disc continuous dryer through a quantitative feeder. The drying process is completed as they flow through the dryer. Dry materials are discharged from the bottom of the dryer. The moisture escaping from the material is discharged into the atmosphere through the moisture outlet at the top of the dryer. The above figure shows the process flow diagram
