Its main role is to remove the moisture in plastic raw materials to ensure the quality and performance of plastic products.
The working principle of plastic dryers is usually based on technologies such as hot air circulation or vacuum drying. Through heating and ventilation, the water in the plastic particles evaporates and is expelled.
Common plastic dryer types include:
1. Hot air dryer: The use of hot air to dry plastic, relatively low cost, simple operation. For example, it is widely used in some small plastic products processing plants.
2. Vacuum dryer: drying in a vacuum environment can more effectively remove water, suitable for plastic varieties with high drying requirements.
Advantages of plastic dryers include:
1. Improve the quality of plastic products, reduce bubbles, defects and other defects.
2. Optimize the production process and improve production efficiency.
3. Extend the service life of the mold.
When choosing a plastic dryer, factors to consider include:
1. Types and characteristics of plastics.
2. Production scale and output demand.
3. Control accuracy of drying temperature and time.
In short, plastic dryers play an indispensable role in the field of plastic processing, which is of great significance to ensure the quality of plastic products and the smooth progress of production.
1. After the end of work every day, clean the inlet and outlet of the dryer to prevent the blockage of plastic particles.
For example, use a soft brush or compressed air to remove debris around the feed port.
2. Regularly clean the air duct and filter inside the dryer to ensure good ventilation effect.
Generally, clean the air duct at least once a week, remove the filter and clean it with detergent, dry it and put it back.
1. Check the working state of the heating element regularly to ensure that it heats normally.
Check once a month whether the connection line of the heating element is loose or broken.
2. Verify the accuracy of the temperature sensor to ensure the accurate control of the drying temperature.
A professional temperature measuring instrument can be used to compare the temperature shown by the dryer once a quarter.
1. Regularly add appropriate amount of lubricating oil to the conveyor belt, transmission chain and other moving parts of the dryer.
It is usually added every two months.
2. Check the wear condition of the bearing, and replace it in time if there is any abnormality.
1. Regularly check whether the electrical circuit is aging or damaged to avoid safety hazards such as short circuit.
A comprehensive inspection is recommended every six months.
2. Ensure that the buttons and indicators on the control panel work properly.
1. Conduct a comprehensive overhaul of the dryer every once in a while (such as every year), including checking the operation of the fan and the performance of the sealing parts.
2. Check whether the shell of the dryer is corroded or deformed, and repair or replace it in time.
1. Keep the installation environment of the dryer dry and ventilated to avoid excessive humidity and dust.
2. Prevent the equipment from strong vibration and collision.
Through the above daily maintenance and maintenance measures, the service life of the plastic dryer can be extended and its work efficiency and stability can be improved.
