The coating receiving electrode has board-like or two kinds of structures of tubular type; Corona discharge electrode (wire electrode) connects the positive pole of electrostatic generator; Forward and backward flat board (straight tube) connects the negative pole of electrostatic generator, forms electric field between corona discharge electrode and the forward and backward flat board (straight tube), and the coating cloud that is not sprayed onto on the workpiece enters into electric field through air-vent; Be ionized to charged cation; Produce attraction with forward and backward flat board (straight tube) inwall, be adsorbed to flow to behind forward and backward flat board (straight tube) inwall and store in the metering recovering mechanism, directly be sprayed onto flowing directly to of forward and backward flat board (straight tube) front surface and store in the metering recovering mechanism.Air-vent plays the effect of penetrating coating cloud, makes that the absorption coating cloud is more thorough; Before lip-deep air-vent interlaced arrangement behind air-vent interlaced arrangement and the air-vent on the straight tube front surface and the straight tube of air-vent and rear plate on the flat board, can guarantee that coating cloud enters in the electric field can be recovered fully.
Two rows before and after straight tube is provided with have the gap between adjacent two straight tubes of every row, and are corresponding before and after the air-vent on the gap between front-seat adjacent two straight tubes and the back row's straight tube, front-seat straight tube with after the straight tube interlaced arrangement of arranging.The absorbability that being provided with of this structure can be improved coating cloud and reclaim more thorough.
Tensioning apparatus plays the effect of traction, stable electrical polar filament.The insulation holder is used for fixing corona discharge electrode.
The present invention adopts the mode of ionization will be suspended in airborne coating particles mist and collects, and improves environment and operating condition, plays the effect of energy-saving and emission-reduction; Less to existing paint line change, equipment investment is little, and organic efficiency is high; Simple to operate, automaticity is high.
