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
The dryer is simple to operate, easy control the material, greatly reducing the labor intensity of workers, also reduce the material pollution in the drying process at the same time.
1. The reducer: the reducer installed in the right side of the machine. The motor was driven by the pulley and the V-belt to the gear unit, the spindle rotation to the rake teeth, and finally the cylinder rotated and get speed of 6~ 10 r / min.
2. The motor base device: The motor was mounted on the right side of the activity board, can be adjusted up and down, so that the V-belt tight fit.
3. Electrical control device (EU standard): All the electrical control, buttons, lights are installed in the control box, the operation can be controlled based on the panel text instructions. The positive and the reversing rotating direction of the stirring shaft can be adjusted according to the characteristics of the material. Generally, it can be controlled in about 5 minutes (ie, after stopping for 5 minutes, then reversing for 5 minutes).
4.Vacuum tube: Used to extract the cylinder evaporation’s solvent (or water) . In the inlet side with a filter,should be covered with filter cloth to prevent the material out.
5. Sealed structure: The spindle at both ends are sealed with PTFE , sealed in a vacuum to achieve a good sealing effect.
6.The mixing shaft with stainless steel thick-walled tube, rake arm rake teeth are made of stainless steel seamless stainless steel plate. Rake board was PTFE plated, scraping the sticky material.
