Continuous plate dryer working principle
The wet material is fed continuously to the first drying layer on the top of the dryer. It will be turned and stirred by rakes when the rake arm rotates and drop down to the outer edge of the large drying plate along the exponential helical line. The material will be moved from the small drying plate to its outer edge and drop down to the outer edge of the large drying plate underneath. Both small and large drying plates are arranged alternately so the materials can go through the dryer continuously. The heat medium can be saturated steam, hot water or thermal oil. The heat will be LED into hollow drying plates from one end and come out from the other end. The dried materials will drop from the last layer of the drying plate to the bottom of the dryer and then moved by rakes to the discharge outlet. The material moisture will be removed from the exhaust outlet on the top cover. For the vacuum-type plate dryer, the moisture will be sucked out by the vacuum pump on the top cover. The dried materials will be discharged from the bottom layer. The drying capability can be improved if the dryer equipped with supplementary devices such as finned heater, condenser for solvent retrieval, bag dust remover, return and mix mechanism, draft fan, and etc.
Disc plate dryer performance characteristics
(1) easy control andEngine & Part strong applicability:
The drying process is optimized by adjusting the thickness of the material layer, the spindle speed, the number of cymbals, the type and size of the blister leaf.
Each layer of drying plate can be heated or cooled by entering the heat medium or the cold medium separately. The temperature control of the material is accurate and easy.
The residence time of the material can be precisely adjusted.
The flow direction of the material is single and there is no back mixing phenomenon. The drying is uniform, the quality is stable, and no mixing is required.
(II) easy operation and easy operation
Dryer driving and parking operations are very simple.
After the feed is stopped, the transport of the material scale leaves the material in the dryer quickly.
Through aspecial large inspection door mirror, the inside of the equipment can be carefully cleaned and observed.
(3) low energy consumption
The material layer is thin, the spindle speed is low, and the material transfer system requires less power and less power consumption.
Drying with conductive heat, high thermal efficiency, low energy consumption.
(4) the operating environment is good, the solvent can be recovered, and the dust emission meets the requirements.
Normal pressure type: Due to the low air velocity in the equipment and the high and low humidity distribution inside the equipment, it is difficult for dust to float to the top of the equipment, so the top moisture outlet the exhaust gas contains almost no dust.
Closed type: Equipped with asolvent recovery device, it can conveniently recover the organic solvent contained in the carrier gas. The solvent recovery device is simple and the recovery rate is high. For materials that are flammable, explosive, toxic, and easily oxidized, nitrogen can be used as acarrier gas to carry out closed-circuit circulation for safe operation. Especially suitable for drying flammable, explosive and toxic materials.
Vacuum type: The disc dryer operates under vacuum, especially suitable for the drying of heat-sensitive materials.
(5) easy installation and small floor space
The entire dryer is shipped and the entire transport is completed. It is only necessary to lift the dryer in place and the installation and positioning are very easy.
Due to the dry disk layout and vertical installation, even the dry area is large and the floor space is small.Continual plate dryer technical characteristics
(a) drying plate
Design pressure: Generally 0.4MPa, up to 1.6MPa.
Maximum use pressure: Generally ≤0.4MPa, up to 1.6MPa.
Heating medium: Steam, hot water, heat transfer oil, hot water heating at 100°c, 100°c to 150°c, saturated steam or supeGas Generation Equipment & Parts rheated steam at ≤0.4MPa, and heat transfer oil at 150°c to 320°c. Heating, >320 °c can be used when electricity, thermal oil, molten salt and other heating methods.
(b) material transfer system
Spindle speed: 1to 10 minutes, electromagnetic or frequency conversion stepless speed regulation.
ArEmergency Light & Indicator Light m: There are 2to 8arm arms fixed to the main shaft on each drying plate.
Leaves: Spliced on the arm, can keep in contact with the surface floating, there are many forms.
Rolling and rolling: For the materials that are easy to agglomerate and need to be crushed, adding aroll in place can strengthen the heat transfer and drying process.
(c) the shell has three types of normal pressure, airtight, and vacuum.
Atmospheric pressure type: Cylindrical or octagonal prism type, there are twoDrying Machine types of integral and split structure. The heating medium inlet and outlet main ducts may be inside or outside the housing.
Closed type: Cylindrical shell, can withstand 5kpa internal pressure, heating medium inlet and outlet main pipeline can be in the shell, but also outside the shell.
Vacuum type: Cylindrical shell, design pressure is 0.1MPa, heating medium inlet and outlet main pipelines are in the shell.
(d) air heaters
Are generally used with large evaporation to enhance drying efficiency.Adaptation materials
