Why does the hopper plastic dryer overheat? How do solve the problem of overheating and overheating?
The operation mode of the ordinary hopper plastic dryer is a fixed operation mode, which is continuously heated by the hot air pipe, and the fan continuously transports the hot air into the drying barrel.
If the fan of the ordinary hopper plastic dryer fails abnormally and keeps working, the hot air duct is continuously heated, and the generated hot air will continue to enter the hopper along the hot air duct, which will cause the temperature in the drying barrel to rise continuously, which will cause The hopper plastic dryer is overheating.
The overheating of the hopper plastic dryer can easily lead to the destruction of raw materials, and even when the temperature reaches the ignition point of the plastic raw materials, it will cause combustion, causing hidden safety hazards and cost losses.
When the heat of the air duct of the hopper plastic dryer exceeds the set temperature within a certain range (such as overheating above 40°C), the over-temperature alarm device will give the heater and fan of the energy-saving hopper plastic dryer a signal to stop working, and the alarm indicator will start Flashing, waiting for professionals to come and handle it correctly, this prevents overheating and overheating from destroying plastic raw materials, and avoids cost losses for production enterprises.
