Detailed Description

The present invention will be further described with reference to the accompanying drawings.

In the figure 1, the device comprises a cathode plate 1 and a collecting device, wherein the collecting device comprises a support 2 and two scraping plates, the support 2 is supported on an upper port of an electrolytic cell and is formed by welding two groups of cross beam groups, each group of cross beam groups comprises two symmetrically arranged cross beam groups, and grooves 5 are symmetrically arranged in the middle of one group of cross beam groups; the two scraping plates are symmetrically fixed on the right half part of the bracket 2, the distance between the two scraping plates is not less than the thickness of the cathode plate 1, and the upper end surfaces 6 of the scraping plates 3 are inclined downwards from left to right and from outside to inside; the middle of the metal disc-shaped cathode plate 1 capable of automatically rotating is provided with a metal rotating shaft 4 fixed with the metal disc-shaped cathode plate 1, two ends of the rotating shaft 4 are supported on grooves 5 of a group of cross beam groups, one end of the metal rotating shaft 4 is connected with a direct current power supply cathode through a lead, the other end of the metal rotating shaft 4 is driven by a slow motor to rotate the cathode plate 1 around the rotating shaft 4 clockwise, and a cathode product generated below the cathode plate 1 is rotated to the upper part of an electrolytic bath;

in the figures 2 and 3, the two scrapers are symmetrically fixed on the right half part of the bracket 2, the distance between the scrapers is not less than the thickness of the cathode plate 1, the upper end faces 6 of the scrapers 3 are inclined downwards from left to right, and the inclination angle is 30-60 degrees, so that the scraped products can flow to the outside of the electrolytic cell along the inclined plane.
