In the technique scheme, described " flowing to consistent " has two-layer connotation: one is meant the identical situation that flows to; Two to be meant that outgassing direction (be gas outlet towards) flows to upslide movie queen direction at the powder that adds tube cell identical for it.The gas outlet of described tracheae with add tube cell and be communicated with to be located at and add in the tube cell for the gas outlet of tracheae, also can be Y shape structure.Described " gas outlet of tracheae is located at and adds in the tube cell ", the gas outlet that its next structuring concept can be a tracheae towards with add tube cell in powder flow to identical, as the gas outlet section of tracheae at least and add and be sleeve structure (shown in accompanying drawing 2) between the tube cell; Also can be tracheae the gas outlet towards and add powder in the tube cell and be acute angle (shown in accompanying drawing 3) between flowing to.Described " gas outlet of tracheae with add tube cell be Y shape structure ", its subordinate concept can be tracheae the gas outlet towards with add tube cell in powder flow to identical (shown in accompanying drawing 4); Also can be tracheae the gas outlet towards and add powder in the tube cell and be acute angle (shown in accompanying drawing 5) between flowing to.
In the above-mentioned technology case, described tracheae is provided with control valve, and this control valve can be that flow control valve also can be a pressure-regulating valve.The described tube cell upper end that adds is communicated with the collection tube cell of cyclone separator through the powder feeding display, and described powder feeding display is that a cross section is greater than the transparent vessel that adds tube cell.
The operation principle of the present utility model and the course of work are: when adding powder for the first time before the electrostatic fluidized bed work, generally need not open the control valve on the tracheae, powder falls into electrostatic fluidized bed automatically under the effect of gravity.After electrostatic fluidized bed work, can produce a kind of continuous upper punch air-flow in the fluid bed, because of this upper punch air-flow opposite with the powder direction of whereabouts, thereby stoped the powder that adds in the tube cell to fall, open the control valve on the tracheae this moment, add the interior powder of tube cell under the air-flow guiding of tracheae, overcome the resistance of upper punch air-flow in the fluid bed, fall in the fluid bed continuously automatically.Can control the continuous of electrostatic fluidized bed by the adjusting of control valve for the powder amount.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
1. because the utility model has been realized automatically continuously not needing in the electrostatic fluidized bed work to shut down to add powder for powder to electrostatic fluidized bed again, and production efficiency improves greatly, and labour intensity obviously reduces, and manually adds powder and compares and have tangible technological progress.
2. owing to the utility model supplies powder automatically continuously, the coating quality problem that what cause because of amount of powder in the fluid bed was effectively controlled in the past, thereby had improved the coating quality of motor rotor core.
3. because tracheae described in the utility model is provided with the control valve of regulating for the powder amount, the applied thickness of the motor rotor core applicator surface by electrostatic fluidized bed is effectively controlled, thereby can requires regulate easily applied thickness according to difference.
4. because the utility model has very positive meaning to mechanization, the automation continuous productive process that develops electrostatic fluidized bed powder coating technology.
