Description
Technical field
The present invention relates to electrostatic spraying apparatus, more particularly to powder spray is sprayed dress in the high-pressure electrostatic powder on object
It sets.
Background technique
Existing electrostatic powder coating device, the electrostatic generator including sprayer He the inside cavity for being placed in the sprayer.This
The electrostatic powder coating device of kind monomer is an electrostatic generator built in a sprayer, is suitable for required spray metal structure ruler
The situations such as dusty spray amount needed for very little or surface area is smaller, the speed of service is low on continuous spray line or the unit time is smaller；Each
The charge capacity that electrostatic powder coating device sprays powder to it does not need too greatly, and electrostatic generator power is smaller, structure size
Also smaller.
But for flying reel or the continuous electrostatic powder coating of plane, such as: cold-rolled steel sheet, galvanized steel plain sheet and aluminium sheet
Metal and nonmetallic front and back powder spray, high due to being sprayed-on object movement speed, the unit time, which needs to spray, to be flowed through
Surface area it is big, needing electrostatic powder coating device to spray, amount of powder is big, and the carrying capacity demand of unit time powder is big.Therefore,
Need to improve the power of electrostatic generator.However, the structure size of powerful electrostatic generator is bigger, can not be arranged on
State the inside cavity of the electrostatic powder spraying device of monomer；And the external electrostatic generator of each sprayer leads to occupied space
Greatly.
" a kind of segmented for electrostatic powder coating is sprayed for this purpose, Chinese patent 201120002882.7 invention
Device ", comprising: crossbeam and at least two injectors for being fixed on the crossbeam, being arranged in a linear along crossbeam length direction.It is this,
Although the sectional type ejector of electrostatic powder suitable for high-speed uniform spray, and by adjust injector between spacing or
Dusting and not dusting for control several injectors of edge, can reach the adjustable effect of jet width.But its shortcoming exists
In:
When crossbeam is conductive metal material, high-voltage output line is connected with crossbeam.Crossbeam and injector as electrode are equal
For metal, it is intended to generate electrostatic field, generates two parts electric field in plain conductor input voltage, one is that injector generates, one
A is that crossbeam generates, and the ability of the electrostatic field or charged powder that cause each injector to generate reduces, and is not able to satisfy high speed
The needs of even spraying both reduce backup capability, while all metal beams and metal injector are exposed and are linked together
Logical high-pressure electrostatic, has the possibility of electric discharge, there are security risks.
2, when crossbeam is conductive metal material, it may be assumed that " crossbeam " is both conduction connector and emitter structure connected body.
If problem occurs for emitter construction, certainly will be possible to also break down in terms of conduction.
If: when occurring non-conductive, it is that the structure failure generation of injector or crossbeam open circuit generate, cannot defines.If
Injector is dismantled, circuit will certainly be dismantled or influences circuit, circuit will also be torn open；
Equally assembling above-mentioned " sectional type ejector " is also the same, increase process and workload.
3, when crossbeam is non-metallic conducting material, high-voltage output line is connected with each injector.High voltage transmission line is direct
It is connected with each injector；It is equivalent to and each injector is linked together by tandem principle.To in a certain of non-end
Open circuit occurs for place, and other injectors power off；Problem occurs at injector or connecting wire one, is intended to check together and more
It changes；Meanwhile each conducting wire is connected with each injector, if injector is more, conducting wire can be very much, and cable is not easy to arrange
Cloth, and occupied space is bigger.
