Integrated treatment device and method for cleaning, reducing and drying electrolytic copper powder

Abstract

The invention belongs to the technical field of electrolysis and particularly relates to an integrated treatment device and a method for cleaning, reducing and drying electrolytic copper powder. According to the integrated treatment device for cleaning, reducing and drying electrolytic copper powder, a filtering layer is arranged inside a cavity of the integrated treatment device, and the cavity is divided into two parts, namely, an upper part and a lower part, by virtue of the filtering layer; a material charging opening, a liquid charging opening, a gas outlet and a material outlet are respectively formed in the upper part of the cavity; and a compressed gas inlet, a liquid outlet and a filtration-suction opening are respectively formed in the lower part of the cavity. By combining a plurality of treatment processes of electrolytic copper powder into the integrated treatment device, production devices can be decreased, the labor strength of operators is reduced, the energy consumption and the loss of the product are reduced and the yield and the quality of the product are improved.

Description

technical field [0001] The invention belongs to the technical field of electrolysis, and in particular relates to an integrated treatment device and method for cleaning, reducing and drying electrolytic copper powder. Background technique [0002] In the production process of electrolytic copper powder, the copper powder produced by electrolysis needs to go through multiple processes such as cleaning, drying, reduction, drying, and grading to become a product. At present, most of them are independent unit processes. Electrolytic copper powder is in the washing machine After washing with deionized water several times for deacidification and saponification, it is sent to the centrifugal dryer in batches to remove most of the water, and then sent to the reduction furnace to continue drying until the water content is lower than 0.1%, and the copper powder is removed by reduction under a hydrogen atmosphere The oxygen contained in the copper powder will generally agglomerate afte...

[0002] In the production process of electrolytic copper powder, the copper powder produced by electrolysis needs to go through multiple processes such as cleaning, drying, reduction, drying, and grading to become a product. At present, most of them are independent unit processes. After washing with deionized water for multiple times, deacidification and saponification, it is sent to the centrifugal dryer in batches to remove most of the water, and then sent to the reduction furnace to continue drying until the water content is lower than 0.1%, and the copper powder is reduced under a hydrogen atmosphere. The oxygen contained in the copper powder will generally agglomerate after passing through the reduction furnace, and it needs to be crushed before continuing to be graded and batch-packed. In this way, the product needs to be transferred multiple times between multiple processes, and each process requires separate equipment. Not only It increases the amount of labor, increases energy consumption, and is prone to leakage and other phenomena during the transfer process.
