[0007] When the fan starts, the dust floating in the feeding hopper is sucked into the collection pipe, and then enters the collection tank along the air outlet plate. The dust moves along the inner wall of the collection tank and finally gathers at the bottom of the collection tank, completing the dust collection.

[0008] Preferably, an air outlet plate two is provided on the upper side of the first air outlet plate, and a rotating column is installed at the upper end of the second air outlet plate, and the rotating column is rotatably connected to the upper end of the collection tank.

[0010] Preferably, the lower end of the collecting pipe is provided with a threaded groove, and the lower end of the collecting pipe is threadedly connected to the upper end of the feeding bin.

[0011] The entire recycling device and the feeding hopper can be fixed by adjusting the collection pipe; conversely, the entire recycling device can be removed from the top of the feeding hopper for easy cleaning.

[0012] Preferably, the collecting tank is shaped like an "A" in frontal view, and a discharge pipe is installed at the bottom of the collecting tank.

[0013] The dust collected in the collection tank can be discharged from the collection tank through the discharge pipe, making it convenient for the dust to be recycled.
