Medium frequency induction heating equipment for dryer

The power of the intermediate frequency power supply is 900kw the surface of the heating temperature cylinder is 800 degrees the diameter of the rotary cylinder dryer is 1300mm and the arrangement length of the inductor is 10000mm.

Features

The number of copper tube windings of .5 is large and the effective coverage area is small. It is recommended to use a copper tube 20x40x2.5mm (3kg/m) for copper tube winding and the 40mm surface is parallel to the surface of the rotary barrel (the vertical winding structure).

1Medium frequency induction heating equipment for dryer Overview:

The power of the intermediate frequency power supply is 900kw, the surface of the heating temperature cylinder is 800 degrees, the diameter of the rotary cylinder dryer is 1300mm, and the arrangement length of the inductor is 10000mm.
Description of induction coil: Using ANSYS Computer Aided Engineering (CAE) software, the electric field and magnetic field are analyzed. The power is 900kw, the diameter of the rotary barrel is 1300mm, and the total arrangement length of the sensor is 10000mm. After the analysis, the arrangement of the inductor coil is obtained. The single inductance is in the range of LH-180uH. The larger the effective area of ​​the induction coil outside the rotary barrel is, the higher the magnetic field efficiency is. The larger the effective area is, the smaller the number of gaps between the coils is. The coil is 25x25x2. The number of copper tube windings of .5 is large, and the effective coverage area is small. It is recommended to use a copper tube 20x40x2.5mm (3kg/m) for copper tube winding, and the 40mm surface is parallel to the surface of the rotary barrel (the vertical winding structure). Three sets of 300kw intermediate frequency power supplies are used to supply power to the three sets of coils, respectively, due to the gap between each set of coils and each set of coils. The length of the arrangement should be calculated according to 9000mm to calculate the number of turns of the copper tube, and the quality, the length of the copper tube section length 40mm width 20mm plus the gap 10mm of the number of turns of the sensor is 180 turns. The diameter of the induction coil is 1400mm and the weight of the sensor is about 1800kg.
