The bottom of the circulating air ducts 10 is connected to an air inlet 11 located on the side surface of the bottom of the furnace chamber 2. Inside the air inlet 11, there is an air distribution plate 12.
[0016] Inside the filtration and purification chamber 9, there is a filtration and purification module 13. On the front and rear side walls of the filtration and purification chamber 9, there are air discharge openings 14 connected to the circulating air ducts 10. At the air discharge openings 14, there are exhaust fans 15.
[0017] The air discharge openings 14 are located above the filtration and purification module 13.
[0018] The filtration and purification module 13 includes a pull-out rack 131. At the bottom of the pull-out rack 131, there is a chassis 132. At the upper part of the pull-out rack 131, there is a filter 136. At the outer end of the pull-out rack 131, there is an iron sealing plate 133. Outside the iron sealing plate 133, there is a handle 134; on the pull-out side of the filtration and purification chamber 9, there is an annular groove 91 that cooperates with the iron sealing plate 133.

[0029] The air inlet is also equipped with a blower.
[0030] The drying process of the present invention is as follows: the enameled flat wire passes through the threading port (long linear opening) on the left side of the furnace, the threading hole on the vertical partition, and the threading port (long linear opening) on the right side of the furnace from left to right. During this process, the enameled flat wire passes through the first drying chamber on the left and the second drying chamber on the right in turn. The electric heating modules in the two drying chambers are controlled according to actual temperature requirements so that the first drying chamber and the second drying chamber maintain corresponding temperatures. The exhaust gas in the furnace is discharged from the air outlet, first passes through the catalytic burner in the catalytic combustion chamber for catalytic combustion to remove flammable and harmful substances in the exhaust gas, and then enters the filtration and purification chamber through the side pipe. After the exhaust gas passes through the filter under the suction of the exhaust fan, it enters the circulating air duct from the exhaust port, and finally enters the furnace under the action of the blower. Under the action of the air distribution plate, the heat generated by the electric heating module is evenly applied to each enameled flat wire, and the hot air passes through the enameled flat wire from bottom to top and is finally discharged from the air outlet.
