Nonwoven Fabric Heater
Professional production of nonwoven fabric heaters
The meltblown process flow is: polymer preparation → melt extrusion → metering pump → meltblown die assembly → melt filament stretching → cooling → receiving device. Meltblown equipment mainly includes: feeding machine, screw extruder, metering pump, meltblown die assembly, air compressor, air electric heater, receiving device, and winding device. For producing polyester and other raw materials, additional devices such as chip drying are required. Auxiliary production equipment mainly includes: die cleaning furnace, electrostatic application device, and spray device.


Features:


1. The medium can be heated to a very high temperature, up to 850°C, while the shell is only 50°C;


2. Fast heating and cooling rates, up to 10°C/s, with stable and rapid temperature adjustment, without issues like temperature lead or lag, suitable for automatic control;


3. The heating element is made of stainless steel alloy material, with high mechanical performance and strength under the influence of high-pressure airflow and water flow;


4. High efficiency, up to 90% or more;


5. Compact size, easy to operate and maintain;


6. Under normal operating conditions, the lifespan can reach over ten years, durable and long-lasting.


 


It is a device that converts electrical energy into thermal energy. The cold medium enters the heater cavity and follows a designed path, fully contacting the flange heating core inside the cavity, reaching the required temperature, and then being sent to the heat-using equipment. The temperature control system of the heater automatically adjusts the heater power based on the feedback signal from the temperature sensor at the heater outlet, saving energy while ensuring heat demand. The electrical control system has built-in overheat protection. If the temperature sensor inside the heater cavity detects an excessively high temperature or a dry-burning condition, it will immediately cut off the power to prevent material deterioration, coking, carbonization, or damage to the heating tube due to dry burning.


Application in meltblown fabric equipment (meltblown nonwoven fabric, meltblown fabric machine):


In the production process of meltblown nonwoven fabric, the compressed air output from the air compressor passes through an inlet dehumidification filter and then enters the air electric heater. After being heated to the set process temperature, it is transmitted to the meltblown die assembly.


The meltblown process has high requirements for hot air. Using a matching control cabinet with an accurate temperature control system can maintain temperature control within a range of ±1°C.
