Embodiment 2

[0029] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the copper powder flushing device 4 is a water spray pipe, and the electrolyte solution is sprayed out circularly through the water spray pipe, and the impact force of the high-pressure solution is used to rinse the copper on the surface of the copper cathode drum 2 Powder makes it sink in the copper powder collecting tank 5, can reach the effect of embodiment 1 equally.

Embodiment 3

[0031] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the soluble copper anode plate 3 is an arc-shaped plate opposite to the copper cathode drum 2, which further increases the soluble copper anode plate 3 and the copper cathode drum 2. Between the effective area, in order to facilitate the collection of copper powder, the copper powder collection tank 5 is made of a plurality of conical tanks arranged in parallel, the lower end of which is funnel-shaped, and in each of the conical tanks is provided with The swirl paddle 10 for realizing swirl flow precipitation is also provided with a variable speed motor 9 for driving the swirl paddle 10 to rotate at the upper end of the copper powder collection tank 5 . During specific implementation, two adjacent tapered tanks are separated by a partition, and a strip-shaped mouth 12 for electrolyte circulation is provided on the partition. In order to facilitate swirl precipitation, the strip-sh...

Abstract

The invention provides a copper powder preparation device and a preparation method thereof. The copper powder preparation device comprises an electrolysis reaction tank, and further comprises a coppercathode drum which is arranged in the electrolysis reaction tank; a soluble copper anode board is arranged in the side, opposite to the copper cathode drum, of the electrolysis reaction tank; a copper powder scouring device is arranged on the other side opposite to the copper cathode drum; a copper powder collection tank connected with the electrolysis reaction tank is arranged below the side close to the copper powder scouring device; a liquid inlet is arranged on one side of the electrolysis reaction tank; a liquid outlet is arranged on one side of the copper powder collection tank; and a copper powder collection opening is further arranged at the lower end of the copper powder collection tank. The copper powder preparation device has the effects that the structure of the electrolysis reaction tank and the installation way of a cathode and an anode are improved, so that the automatic scraping of copper powder on the copper cathode drum can be achieved; the powder scraping speed is controlled; the different sizes of the copper powder caused by the uneven powder scraping time control is avoided; the particle sizes can be controlled; apparent density of the copper powder is small and the specific surface area of the copper powder is large; consecutive powder preparation is achieved; and the production efficiency is improved significantly.

Description

technical field [0001] The invention relates to electrolytic copper technology in the metallurgical industry, in particular to a copper powder preparation device and a preparation method. Background technique [0002] As an emerging material, fine metal powder has attracted widespread attention, and a lot of preparation equipment and preparation methods have been produced. The powder prepared by the electrolytic method has high purity, good compaction performance, easy control of particle size, and can obtain fine metal powder that is difficult to prepare by other methods, so it has attracted the attention of the industry. [0003] In the conventional electrolytic production process, it is often necessary to periodically scrape the powder, and the scraping time is inconsistent, and the thickness of the metal powder on the cathode plate is also inconsistent, so it is difficult to obtain a finer and more uniform powder with a small loose packing ratio and a large specific surf...
