[0033] (2) In order to make the paint on the surface of the galvanized square tube dry quickly, first start the heater 501, wait for the heater 501 to reach a suitable temperature, and then start the blower 502. The air inlet end of the blower 502 draws in the outside air and filters it, and then enters the inner cavity of the heater 501 through the air outlet end for heating. The heated air can enter the inner cavity of the air guide cover 504 through the air outlet pipe 503, and is guided by the air guide cover 504 to quickly dry the paint.
