Online weighing device for residual polar plate

Abstract

The invention relates to the technical field of metal smelting, and discloses an online weighing device for a residual polar plate. The residual polar plate is conveyed by a chain type conveying mechanism; the online weighing device is arranged on the chain type conveying mechanism and comprises two weighing modules which are symmetrically distributed on the two sides of the chain type conveying mechanism. The weighing modules are vertically arranged, the upper ends of the weighing modules are hinged to a suspension base, and the lower ends of the weighing modules arehinged to a bearing arm. The other end of the bearing arm is hinged to a cantilever support, the suspension support is fixed to the cantilever support through a connecting piece, the chain type conveying mechanism comprises aconveying chain making contact with the residual polar plate, the conveying chain is formed by sequentially connecting a plurality of flat chain links and chain links with hooks in series, the distance between the chain links with the hooks is a specific pitch, and the residual polar plate is pushed by the chain links with the hooks; the online weighing device further comprises a safety arm, the safety arm is provided with a plane section higher than the upper plane of the bearing arm at the middle section of the bearing arm, the tail end of the plane section is provided with a lower slope, and the tail end of the bearing arm is higher than the tail end of the lower slope of the safety arm.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal smelting, in particular to an online weighing device for butt plates. Background technique [0002] In the production process of electrolytic copper, blister copper with a copper content greater than 98% is poured to make an anode, and a stainless steel plate is used as a cathode, and the cathode and anode plates are placed in an electrolytic cell containing an electrolyte made of sulfuric acid and copper sulfate, and energized Dissolving the copper anode into the copper ion mobile stainless steel cathode plate to obtain electrolytic copper with a purity higher than 99.99%. During this process, the anode copper plate is continuously dissolved, so it will continue to become thinner. After reaching the specified operating cycle, Stop the energization of the electrolytic cell. At this time, the copper anode remaining in the cell is called "copper anode residue plate", referred to as the res...

AI Technical Summary

Problems solved by technology

In the past production process, some enterprises will select some overweight residual plates that are suitable for the use of clean liquid through manual judgment.

There are also some companies that return all the residual plates that have completed the specified cycle to re-refine the anode plates, resulting in unnecessary waste, which is also inconsistent with the national policy of "energy saving and emission reduction"

[0004] At present, the weighing measurement method adopted by all domestic anode scrap washing units is the whole stack weighing after the packing process is completed. This method can only roughly calculate the overall anode scrap rate relative to the weight of the anode plate in the tank, and cannot Accurately weigh a single butt plate, let alone provide relevant data guidance for subsequent production
