Be applied to preceding processing apparatus of black hole and shadow

The utility model discloses a be applied to preceding processing apparatus of black hole and shadow, including the sender, set up the clearance mechanism on the sender to reach and clear up the recovery mechanism that the mechanism is connected, the sender runs through into board mouth and play board mouth, clearance mechanism includes that the air current removes bits sections and liquid clearance section, and the air current removes bits period number in a liquid clearance section the place ahead, retrieves the mechanism and connects the air current and remove bits section and liquid and clear up section. The utility model provides a simple science of be applied to preceding processing apparatus of black hole and shadow design through the effect of ionic wind machine, makes NC drilling back, and article must be produced in being adjusted into not charged to the uneven production article of charge distribution, blows the effect of ( ionic wind ) downdraught on through, effectively clears up the pore wall for
