[0031] Refer to the instruction manual appendix Figure 1-6 A powder drying device includes a drying tank 1. A hollow vent pipe 2 is fixedly installed inside the drying tank 1. A hot air device is connected to the outside of the vent pipe 2, which can be a hot air blower. A spiral guide plate 3 is fixedly connected to the outer wall of the vent pipe 2. The side of the guide plate 3 away from the vent pipe 2 is flush with the inner wall of the drying tank 1. A baffle 4 is fixedly connected to the bottom of the guide plate 3. A drying air duct 5 connected to the vent pipe 2 is provided on the baffle 4. A discharge outlet is located at the top of the drying tank 1. The discharge port 6 and the top of the guide plate 3 are attached together. The bottom side wall of the drying tank 1 is provided with a feed port 7. The feed port 7 is movably connected to a shielding component 8, which is used to block the feed port 7. When in use, the shielding component 8 is opened, and the powder to be dried is added to the inside of the drying tank 1 through the feed port 7. Multiple drying air outlets 9 are provided on the vent pipe 2. Hot air is blown out from the drying air outlets 9 after passing through the vent pipe 2, thereby realizing the drying treatment of the powder inside the drying tank 1.
[0032] In use, the powder to be dried is placed at the bottom of the drying tank 1. Hot air enters the drying duct 5 through the air pipe 2, blowing the powder at the bottom of the drying tank 1 and causing it to move upward along the guide plate 3. The guide plate 3 increases the distance the powder moves inside the drying tank 1, thereby improving the drying effect of the powder inside the drying tank 1. After the powder moves upward along the guide plate 3 to the outlet 6, a collecting device is installed at the outlet 6 to collect the powder into the collecting device. The collecting device is a container with a hollow interior.
[0033] The hot air device includes a blower 10, the air outlet of the blower 10 is connected to a ventilation pipe 2 through a pipe, and an electric heating element 11 is installed inside the ventilation pipe 2. The electric heating element 11 is set inside the ventilation pipe 2 to increase the temperature of the air blown out from the ventilation pipe 2.
[0034] The baffle 4 is provided with a downwardly inclined dispersion air duct 12. The dispersion air duct 12 is connected to the vent pipe 2 through the pipe. The downwardly inclined dispersion air duct 12 blows the powder piled at the bottom of the drying tank 1, causing the powder at the bottom of the drying tank 1 to be scattered. The drying air duct 5 blows the scattered powder to the guide plate 3, thereby improving the powder blowing efficiency.
[0035] An auxiliary air duct 13 is fixedly connected to the lower end of the baffle 4. The auxiliary air duct 13 is connected to the air pipe 2 through the pipe. The auxiliary air duct 13 is used to blow the powder piled at the bottom of the drying tank 1, so that the powder at the bottom of the drying tank 1 can more easily drift to the guide plate 3.
[0036] The auxiliary air duct 13 is set in a Z-shape to reduce the amount of powder entering the auxiliary air duct 13.
[0037] An auxiliary power duct 14 is connected to the dry air outlet 9. The auxiliary power duct 14 is attached to the vent pipe 2 and is inclined upward.
[0038] The auxiliary power duct 14 includes an arc-shaped power duct 14-1 and a vertically arranged anti-blocking duct 14-2. The lower end of the anti-blocking duct 14-2 is connected to the lower end of the arc-shaped power duct 14-1, and the upper end of the anti-blocking duct 14-2 is connected to the drying air outlet 9.
[0039] The arc-shaped power pipe 14-1 is inclined upward, thereby pushing the powder on the guide plate 3, causing the powder on the guide plate 3 to continue to float upward until it enters the collection device through the discharge port 6. The anti-clogging pipe 14-2 is vertically set to reduce the amount of powder entering the vent pipe 2 through the arc-shaped power pipe 14-1 and the anti-clogging pipe 14-2.
[0040] A rubber sealing frame 16 is installed on the feed inlet 7, which is used to seal the feed inlet 7.
[0041] The end of the shielding component 8 is hinged to the feed inlet 7. The side of the shielding component 8 away from the vent pipe 2 is rotatably connected to the locking handle 17. The locking handle 17 is fixedly connected to the locking tongue 18 that cooperates with the feed inlet 7 through the rotating shaft. When in use, the shielding component 8 is rotated so that the shielding component 8 and the feed inlet 7 are in contact. At this time, the locking handle 17 is rotated to lock the shielding component 8 on the feed inlet 7 through the locking tongue 18.
[0042] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
