Extremely upper copper powder scrapes.After the nineties in last century, China starts using Chongqing Smelter as the copper powder manufacturing enterprise of representative using machine
The mode of tool brush dust substitutes artificial brush dust, but since equipment operation site environment limits, and the reliability of equipment, stability are by shadow
It rings, fails effectively to be promoted always.In addition, cathode and anode difference in existing copper powder preparation process, need to make special
Cathode, complex process, manual brush dust human factor influence big.
Utility model content
Purpose of the utility model is to solve the technical problems existing in the prior art, provide a kind of structure it is simple,
Easily operated, high degree of automation, human factor influence that copper powder automatic powder discharging can be made in electrolytic process small and that shedding effect is good
Device.
In order to achieve the above object, the utility model uses following technical scheme: can make in a kind of electrolytic process copper powder from
The device of dynamic powder falling, the electrolytic cell including being equipped with electrolyte, the top of the electrolytic cell is equipped with more parallel conducting rods, described
Conducting rod is connect with the rectification power distribution cabinet for providing regular direction switching current and the difference of adjacent conducting rod and rectification power distribution cabinet
Electric current pole connects, and the lower section that identical electrode copper sheet and every piece of electrode copper sheet are hung on every conducting rod is horizontal equipped with gas
Flow tube is uniformly provided with multiple gas holes at the top of the gas flow tube and gas flow tube is connect with the nitrogen appendix being vertically arranged.
Further, the nitrogen appendix is equipped with nitrogen air volume regulating valve.
Further, the size of the electrode copper sheet is 550 × 520mm.
Further, the conducting rod is 12.
The utility model has the advantages that compared with the prior art can make copper powder certainly in the utility model electrolytic process
The device cathode of dynamic powder falling is identical with anode, and the electrode copper sheet after being all made of shearing is as material, without making dedicated cathode,
By providing the rectification power distribution cabinet of regular direction switching current current direction is periodically converted automatically in electrolytic process, to make
The polarity for obtaining electrode copper sheet correspondingly converts automatically, and cathode before is converted to anode, and anode before is converted to cathode, at this time
It is started shedding off before conversion for the copper powder on cathode electrode copper sheet, to make copper powder fast-falling, using filling compressed nitrogen stripping
Mode will convert the preceding copper powder on cathode electrode copper sheet, and quick stripping falls into electrolytic cell automatically, and treatment process is simple, is easy to grasp
Make, high degree of automation can effectively avoid the adverse effect of human factor, and shedding effect is good, and greatly reduces cost of labor.
