Description
Technical field
The present invention relates to electrostatic spraying apparatus, particularly relate to the high-pressure electrostatic powder spray equipment of powder spray on object.
Background technology
Existing electrostatic powder coating device, comprises sprayer and is placed in the electrostatic generator of inside cavity of this sprayer.The electrostatic powder coating device of this monomer is a built-in electrostatic generator of sprayer, is applicable to required spray metal physical dimension or surface area is less, the situations such as dusty spray amount is less needed for the speed of service low or unit interval on continuous spray line; The charge capacity of each electrostatic powder coating device to its ejection powder does not need too large, and electrostatic generator power is less, and its physical dimension is also smaller.
But, for flying reel or the continuous electrostatic powder coating of plane, as: metal and the nonmetallic front and back powder sprays such as cold-rolled steel sheet, galvanized steel plain sheet and aluminium sheet, due to high by painting objects translational speed, unit interval needs the surface area of spray stream warp large, need electrostatic powder coating device to spray amount of powder and want large, the carrying capacity demand of unit interval powder is large.Therefore, the power improving electrostatic generator is needed.But the physical dimension of powerful electrostatic generator is larger, the inside cavity of the electrostatic powder spraying device of above-mentioned monomer cannot be arranged on; And all external electrostatic generator of each sprayer causes taking up room greatly.
For this reason, Chinese patent 201120002882.7 invention " a kind of sectional type ejector for electrostatic powder coating ", comprising: crossbeam and be fixed at least two injectors be arranged in a linear on this crossbeam, along crossbeam length direction.This, although the sectional type ejector of electrostatic powder is applicable to high-speed uniform spraying, and by regulating the spacing between injector or controlling dusting and not dusting of the some injectors of edge, the effect that jet width is adjustable can be arrived.But its weak point is:
When crossbeam is conductive metal material, high-voltage output line is connected with crossbeam.Crossbeam and be metal as the injector of electrode, all electrostatic field will be produced, produce two parts electric field at plain conductor input voltage, one is that injector produces, and one is that crossbeam produces, the ability of the electrostatic field causing each injector to produce or charged powder reduces, can not meet the needs of high-speed uniform spraying, both reduced backup capability, all metal beam and metal injector all expose and are linked together logical high-pressure electrostatic simultaneously, there is the possibility of electric discharge, there is potential safety hazard.
2, when crossbeam is conductive metal material, that is: " crossbeam " is conduction connector, is again emitter structure connected body.If emitter construction generation problem, certainly will likely also break down conduction aspect.
If: when occurring non-conductive, be that the structure failure of injector produces or crossbeam open circuit generation, can not be clear and definite.If dismounting injector, will certainly dismantle circuit or affect circuit, circuit also will be torn open;
Same assembling above-mentioned " sectional type ejector " is also the same, increases operation and workload.
3, when crossbeam is non-metallic conducting material, high-voltage output line is connected with each injector.High voltage transmission line is directly connected with each injector; Each injector is equivalent to be linked together by series connection principle.Thus, there is open circuit in certain of non-end, the equal power-off of other injector; There is problem at injector or connection wire one place, all will check together and change; Meanwhile, each root wire is connected with each injector, if when injector is more, wire can be a lot, and cable is not easily arranged, and it is larger to take up room.
