Dry electrostatic spraying system

Abstract

The invention provides a dry electrostatic painting system. The dry electrostatic painting system comprises a painting chamber, an air supplying device, a circulating pipeline, a conveyer, paint mist electrostatic adsorption boxes and an electrostatic generator. Painting guns are arranged on the two sides of the interior of the painting chamber, and a conveying belt used for bearing a workpiece and a grating plate are arranged at the bottom of the painting chamber; the air supplying device is mounted on the top of the painting chamber, and the air supplying device is communicated with the top of the painting chamber through an air supplying pipeline with an air outlet right facing the grating plate; the conveyer is arranged below the painting chamber, and a plurality of paint mist electrostatic adsorption boxes which are sequentially arranged and are used for adsorbing paint mist are arranged on the conveyer; the electrostatic generator is electrically connected with the paint mist electrostatic adsorption boxes; and the circulating pipeline is used for conveying air exhausted out of the paint mist electrostatic adsorption boxes to the interior of the air supplying device for circular air feeding. The defect that in the prior art, a circular liquid medicine purifying system is low in energy consumption during use is overcome, the production cost is reduced, the structure is reasonable, the paint mist removing effect is good, and the system is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of painting and spraying equipment, in particular to a dry electrostatic painting system. Background technique [0002] In the production of modern automobiles, there is a demand for body-in-white coating. The painted body has commodity attributes, including aesthetics, weather resistance, and anti-corrosion. [0003] After the electrophoresis of the body-in-white, the spraying of intermediate coating, topcoat and varnish begins. Most factories use robot spraying. The paint or water-based paint is negatively charged in the hanging cup of the robot. The atomized paint mist settles on the surface of the body due to electrostatic adsorption and gravity. , The paint adhesion rate is 66-85%. The rest of the paint mist is a pollutant and needs to be removed. [0004] The spray booth is a place where various products are sprayed. Because the spraying work area will produce a large amount of paint mist gas, it is necessary ...
