[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0019] The following describes an embodiment of the utility model based on its overall structure.

[0020] like Figure 1 The specific embodiment of the hot air conveying device of the metal dryer shown includes a filtering device 1, a blowing device 2 and a heating device 3; the filtering device 1 is slidably connected to the upper part of the blowing device 2; the heating device 3 is slidably connected to the lower part of the blowing device 2; the filtering device 1 includes a frame 4 and a screen 5; the screen 5 is installed in the frame 4; the blowing device 2 includes a protective shell 6 and a fan 7; the fan 7 is arranged in the protective shell 6; the heating device 3 includes an outer shell 8 and a heating pipe 9; the heating pipe 9 is multiple and evenly distributed inside the outer shell 8.

[0021] Specifically, the filter device 1 of the utility model is slidably connected to the upper part of the blowing device 2, and the heating device 3 is slidably connected to the lower part of the blowing device 2, adopting a segmented connection. No matter which functional module has a problem, it can be quickly replaced and repaired.

[0022] Specifically, the fan 7 is started to extract the air passing through the screen 5 and blow it toward the heating tube 9, so as to achieve the effect of blowing hot air for drying.

[0023] In other preferred embodiments, Figure 2 , Figure 3 and Figure 4 As shown, a slide groove 10 is provided at the lower portion of the frame 4, and a limit opening 11 is provided at the port; a slide rail 12 is provided at the upper portion of the protective shell 6, and a limit block 13 is provided at the port; the upper slide rail 12 of the protective shell 6 is slidably connected in the slide groove 10, and the limit block 13 is located at the limit opening 11 to prevent falling off; a slide groove 2 14 is provided at the lower portion of the protective shell 6, and a limit opening 2 15 is provided at the port; a slide rail 2 16 is provided at the upper portion of the outer shell 8, and a limit block 2 17 is provided at the port; the upper slide rail 2 16 of the outer shell 8 is slidably connected in the slide groove 2 17, and the limit block 2 17 is located at the limit opening 2 15 to prevent falling off.
