[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. During the zinc spraying process on aluminum flat tubes, some zinc powder splashes outwards along with debris from the outer wall of the tubes. During this process, the air pump operates, and the air intake filter blocks larger metal debris. Smaller metal debris, along with the zinc powder, passes through two air guide channels, then two air intake channels, and finally enters the screening filter in the screening box via the air pump. Subsequently, the screening motor operates, driving two rotating blocks. As the two rotating blocks rotate, they first lift two protrusions, causing the vibrating plate to move upwards. At this time, the multiple springs at the upper end... In the compressed state, the multiple springs at the lower end are in a stretched state. When the two rotating blocks separate from the two protrusions, the multiple springs at the upper end and the multiple springs at the lower end reset respectively. The two rotating blocks repeat the above action to screen the zinc powder and smaller metal shavings in the screening screen. The zinc powder falls into the lower end of the screening box. Pulling the screening box outward separates it from the vibrating plate, allowing the zinc powder inside the screening box and the metal shavings on the screening screen to be removed. This achieves the purification and recycling of zinc powder, prevents it from affecting the health of workers, and avoids the waste of zinc powder.

[0013] 2. This utility model is equipped with an adjustment motor. When the adjustment motor is running, it drives the adjustment block, connecting rod and spray head to move, and spray zinc powder back and forth on the surface of the aluminum flat tube located on the support base, so as to spray the surface of the aluminum flat tube evenly and quickly.
