After several days of careful making, drying machine special calcium carbonate disc dryer finally smoothly delivery.
Disc dryer is a kind of high efficiency conduction type continuous drying equipment. The special structure and working principle determines that it has high thermal efficiency, low energy consumption, with the characteristics of small size, simple configuration, convenient operation, good operating environment, the drying operation is widely used in chemical, medicine, pesticide, food, feed, agricultural and sideline products processing industry. In the use of various industries in the practice of high praise. Is the production of manufacturing pressure, vacuum sealed, three types, 1200, 1500, 2200, 3000 and four specifications, design three kinds of material according to customer demand: A (Tan Gang), B (the parts contact with material are made of stainless steel (C), on the basis of B, the increase of steam pipe, main shaft and bracket for stainless steel the cylinder body and the top cover, lined with stainless steel), dry area of 4 ~ 180m2, total series products of various types, and can provide a variety of auxiliary equipment matching, users can meet the needs of various material drying.
The upper part of the wet material from the feeder to the first continuous disc dryer drying layer on the rake arm rakes the rotary motion to rake leaves continuously stir material. The material flows along the spiral surface of the drying plate, was transferred on the small drying plate to the outer wheel rim, drying and fell to the bottom of the material from the outer edge, to move and drop down from its central hole under a layer of small plate in the drying drying plates. The size of the drying plate is arranged alternately up and down, and the material can flow continuously through the dryer. The heating medium is arranged in the hollow drying plate, and the heating medium is provided with saturated steam, hot water and heat conducting oil, wherein, the heating medium is drawn from one end of the drying disc and is exported from the other end. The dried material falls from the last layer of drying tray to the bottom of the shell, and is finally discharged from the rake blade to the discharge port. The wet parts are overflowed from the material and are discharged from the drain holes arranged on the top cover, and the moisture of the vacuum type disk dryer is drawn out by the vacuum pump mouth at the top cover, and the dry material discharged from the bottom layer can be directly packed. By adding fin heater, solvent recovery condenser, bag type dust remover, dry mixing structure, fan and other auxiliary equipment, can improve the production capacity of dry, dry paste and heat sensitive material can be easily recycled solvent, and can carry on the thermal decomposition and reaction.
Structure principle of disc dryer:
(1) drying tray;
1, design pressure: generally 0.4MPa, maximum 1.6MPa.
2, the highest pressure: less than 0.4 MPa, up to 1.6 MPa.
3, heating medium: steam, hot water, thermal oil, dry disc temperature are less than 100 when using hot water heating, 100 to 150 DEG C with less than 0.4 MPa saturated steam or superheated steam heating, the temperature of 150 DEG with the heat conducting oil heating at 320 DEG C, >320 can use electricity, heating oil, molten lead salt etc..
(two) material delivery system
1, spindle speed: 1~10 RPM / electromagnetic or variable frequency stepless speed regulation.
2. Rake arm: each layer of drying tray has 2~8 arm fixed on the main shaft.
3, rake leaves: twisted on the rake arm, can float with the surface to keep in touch, there are many types.
4, roll: roll easy to agglomerate and need to broken material, in the proper place with roller roll, can strengthen heat transfer and drying process.
There are three types of atmospheric, airtight and vacuum
1, atmospheric type: the original cylinder or eight prism shape, there are two structures of the whole and the opposite. The heating medium inlet and outlet main pipe can be in the shell or in the shell.
2, closed type: cylindrical shell, can withstand 5Kpa pressure, heating medium import and export, the main pipe can be in the shell, or in vitro.
3, vacuum type: cylindrical shell, the design pressure is external pressure 0.1MPa, heating medium import and export main pipe in the shell.
