Product Description
1200mm Diameter Sludge Continous Stirring Harrow Paddle Rotary Vacuum Dryer
vacuum rake dryer is a new type drying machine ,which is designed with the combination of oar blade dryer heat drying principle, with a higher drying efficiency, for a variety of raw materials.
The inner equipped oar blade and screw with continuous ,axial and radial mixing of raw materials ,make the materials to be dried more evenly.With applied both oar blade and screw, when the raw materials were turned over by mixing blades, they speed up the materials contact with heating surface of the dryer,so heat transfer rate is increased,and is conducive to moisture evaporation.
Product Structure
2.1 The loading cylinder of raw materials will be equipped with heating jacket,and heat insulation layer will be equipped outside the jacket,which will prevent the heat be transferred ,and also reduce the heat loss. Discharge hole is equipped with the lower part of the cylinder, on the top of the cylinder with two feeding holes and an air exhaust outlet.When feeding,the raw materials should be fed equally from the two feeding holes,the best feeding capacity is about 60%-80% of the volume of the cylinder,the max feeding capacity should not exceed 80%,otherwise will affect the smooth discharge of gas evaporation .When the sticky raw material is feeding,the feeding capacity should be reduced, to prevent the drive motor overloaded, damage to equipment.
2.2 Hollow shaft is set inside the center of of the cylinder,in heating medium will be put into the shaft( like hot conduction oil or hot water).
2.3 On the hollow shaft distributed with oar blades with certain angle,the oar blades are also hollow within heating transferred,inlet and outlet of hot oil conduction are equipped inside of the blades,to ensure the heat transfer efficiency during the drying
2.4 Seals: Packing seals are equipped during shaft and cylinder.
2.5 Transmission:Except the special models,we normally apply the chain or gear transmission style.Pivot bear apply duplex bearing combination ,with tapered roller bearing and deep groove ball bearing combined,to meeting the requirements of radial and axial force.
Product Structure Features
1. Being installed stirrer in the machine, it makes raw material form the state of continuous circle inside the body, so heating uniformity of raw material is raised greatly.
2. Being installed stirrer in the machine, slurry and paste shape material can be dried easily.
3. Special design for discharging port, make better sealing and less material accumulation, discharge is easy.
4. There are two seal model, mechanical seal and packing seal. The design supply good seal and long life.
5. The special techniques of shaft and rake support high strength and concentric.
6. The medium in shaft and vibration adding equipment will be equipped by requirement
7. Use different filter form according to different material.
Product Application
The following raw materials from pharmaceutical industry, food-stuff industry, chemical industry and so on can be dried.
1.Suitable for pulpiness, paste-like mixture of powder raw materials
2.Thermal sensitive raw materials having the requirement to dry at lower temperature
3.Raw mate rials that are easy to oxidized or explode and have strong irrtative or toxic
4.Raw materials that need to recover solvent
Product Working Principle
The main structure of oar blade harrow dryer are round cylinder and one rotary hollow shaft equipped in the center of the cylinder.On the shaft are distributed hollow oar blades,the heating are transferred by jacket in the cylinder and the surface of the hollow blades,and the moisture evaporated.During heating,the blades will also mix the materials,so that update the heating area.It is a continuous heating transferred dryer.
