[0031] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-7 The utility model provides a technical solution: a circulating drying box, including a drying box body 1, a hot air box 2, a fan 3, a heating device 4, a dust filter 5, a fixing mechanism 6, a fixing block 7, a fixing rod 8, a fixing plate 9, a fixing column 10, a hot air hood 11, a drying box 12, a connecting plate 13 and a connecting track 14.

[0033] When using this circulating drying oven, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, drying boxes 12 are arranged at equal intervals inside the drying box body 1, and the materials to be dried are evenly placed in the drying boxes 12, and then the fan 3 and the heating device 4 installed in the middle of the hot air box 2 are started, and the air blown out by the fan 3 is heated by the heating device 4, and the dust filter 5 is plugged and installed in the middle of the hot air box 2. The dust filter 5 is arranged to facilitate filtering of the hot air, and prevent the hot air from bringing external dust into the drying box body 1 and attaching to the materials, thereby achieving a good dust prevention effect. The filtered hot air is transported to the drying box body 1 through the hot air hood 11, and the hot air hood 11 is arranged at equal intervals inside the drying box body 1, and the hot air hood 11 is at the same height as the drying box 12, and the hot air hood 11 is symmetrically arranged on the left and right sides of the drying box 12, so that the hot air can be evenly and fully transported to the materials inside the drying box 12, and the materials are circulated and dried evenly;

[0034] Moreover, an exhaust valve is installed at the rear end of the drying box body 1, which is not shown in the figure. The excess gas is discharged outward through the exhaust valve. When the drying is completed, the power is turned off and the door on the front side of the drying box body 1 is opened. Figure 6 and Figure 7 As shown, the drying box 12 is pulled forward, and the drying box 12 drives the connecting plate 13 and the connecting track 14 to slide, so that the drying box 12 can be easily removed from the interior of the drying box body 1, so as to facilitate the taking and placing of materials. Figure 5 As shown, the fixing mechanism 6 is symmetrically arranged at the front and rear sides of the upper end of the dust filter 5, and the fixing mechanism 6 includes a fixing block 7 fixedly connected to the upper end of the hot air box 2, a fixing rod 8 rotatably connected to the middle of the fixing block 7, a fixing plate 9 for limiting, and a fixing column 10 fixedly connected to the front and rear sides of the upper end of the dust filter 5;

[0035] By rotating the fixing rod 8 to 90°, the fixing rod 8 and the fixing block 7 rotate, and the torsion spring at the connection between the fixing rod 8 and the fixing block 7 is elastically deformed, the fixing rod 8 drives the fixing plate 9 to rotate, and the width of the fixing plate 9 is smaller than the opening size of the fixing column 10. At this time, the fixing plate 9 is disengaged from the fixing column 10, and then the limit on the fixing column 10 is released, and then the dust filter 5 is pulled upward, and the dust filter 5 drives the fixing column 10 to completely disengage from the fixing plate 9, so as to facilitate the removal of the dust filter 5 from the heating device 4, thereby facilitating the cleaning of dust on the dust filter 5 and preventing the dust filter 5 from being blocked during long-term use.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
