Abstract
The utility model provides a powder washing groove for electrolytic copper powder and relates to a powder washing groove for a washing process of a copper powder manufactured through an electrolytic process. The powder washing groove for the electrolytic copper powder is characterized by comprising a washing groove body, a separating screen filter plate and a filter cloth. One end of the groove body is open and the bottom of the groove body is provided with a liquid outlet. The separating screen filter plate is a filter pore plate which is horizontally fixed on an inner wall of a lower-middle portion of the groove body. The filter cloth covers the separating screen filter plate. When the electrolytic copper powder releases powder, electrolytic liquid and the copper powder are put into the washing groove. After natural filtration, the copper powder is washed through permeation of ion adding exchange water. On one hand, the washing groove guarantees washing effect by utilizing permeating function of water. On the other hand, any damage to tree-shape of the copper powder is prevented during the washing process. The powder washing groove for the electrolytic copper powder is simple in structure, convenient to use, and capable of lowering adverse effect of the washing process to the tree-shape of the copper powder. Moreover, the powder washing groove for the electrolytic copper powder can effectively guarantee sintering, suppressive and electric conduction properties of the electrolytic copper powder.
Description
Technical field
A kind of electrolytic copper powder wash the powder groove, what relate to a kind of washing process that adopts the copper powder that electrolysis produces washes the powder groove.
Background technology
Electrolytic copper powder is mainly used in industries such as diamond tool, powdered metal parts, electrical carbon, friction material.Along with the fast development of PM technique, the demand of electrolytic copper powder is constantly increased, so the continuous sustainable growth of the production scale of electrolytic copper powder.Because the electrolytic copper powder microscopic appearance is dendroid, has determined electrolytic copper powder to have agglutinating property and briquettability preferably, simultaneously because copper has extraordinary electric conductivity, so the application of electrolytic copper powder is constantly expanded.
Electrolytic copper powder is produced through electrolysis, and its microscopic appearance is decided by the influence of electrolysis, therefore in electrolytic process, needs only control copper acid concentration and current density, can obtain dendritic copper powder.And processes such as the dry reduction of follow-up washing all will damage dendroid, can agglutinating property, briquettability and the electric conductivity of electrolytic copper powder be had a negative impact.
Summary of the invention
The purpose of the utility model is exactly the deficiency that exists to above-mentioned prior art, provides a kind of washing process that can reduce to the adverse effect that the copper powder dendroid produces, effectively guarantee electrolytic copper powder agglutinating property, briquettability and electric conductivity electrolytic copper powder wash the powder groove.
The purpose of the utility model realizes through following technical scheme.
A kind of electrolytic copper powder wash the powder groove, it is characterized in that its structure comprises:
The washing cell body---this cell body be a upper end be uncovered, going to the bottom has the cell body of leakage fluid dram;
At a distance from the sieve filter---this is the orifice filter of a horizontal fixed on the inwall of cell body middle and lower part at a distance from the sieve filter;
Filter cloth---this filter cloth covers on the sieve filter.
A kind of electrolytic copper powder of the utility model wash the powder groove, it is characterized in that describedly being fixed in apart from 10-20cm place, sink cell body bottom at a distance from the sieve filter; Above the even circular hole of distribution 2-5cm.
A kind of electrolytic copper powder of the utility model wash the powder groove, it is characterized in that described filter cloth is the nanometer filter cloth.
A kind of electrolytic copper powder of the utility model wash the powder groove, adopt this sink to utilize the osmosis of water on the one hand, guarantee clean result, in washing process, can not cause any destruction on the other hand to the dendroid of copper powder.Simple in structure, easy to use, can effectively reduce washing process to the adverse effect that the copper powder dendroid produces, effectively guarantee electrolytic copper powder agglutinating property, briquettability and electric conductivity electrolytic copper powder wash the powder groove.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of electrolytic copper powder wash the powder groove, its structure comprises: washing cell body 1---this cell body be a upper end be uncovered, going to the bottom has the cell body of leakage fluid dram 2; At a distance from sieve filter 3---this is the orifice filter of a horizontal fixed on the inwall of cell body middle and lower part at a distance from the sieve filter; Filter cloth 4---this filter cloth covers on the sieve filter.
During operation, adopt stainless steel to process the uncovered trough in top, bottom land is provided with liquid outlet, is adding one deck from the about 10-20cm of bottom land place at a distance from the sieve filter, and the separated filter that sieves is used the PVC material, above the circular hole of even distribution 2-5cm, cover one deck nanometer filter cloth in the above.
When electrolytic copper powder is put powder, all electrolyte and copper powder are got in the sink, after the natural filtration, add ion exchange water through the infiltration washing, after water has permeated, add water again, repeat last washing.On in washing process, guaranteeing once water portion all infiltration is clean, can add ion exchange water again when just also staying one deck water on the copper powder surface, guarantee direct ingress of air of copper powder, prevent copper powder contact oxidization of copper powder.When sulfate ion content in the infiltration water (detecting) during, promptly represent copper powder washes clean less than 0.002g/L with barium chloride solution.Adopt this sink to utilize the osmosis of water on the one hand, guarantee clean result, in washing process, can not cause any destruction on the other hand the dendroid of copper powder.
