Insoluble frame-shaped anode structure capable of collecting acid mist

Abstract

The invention provides an insoluble frame-shaped anode structure capable of collecting acid mist. The insoluble frame-shaped anode structure comprises a frame-shaped anode to which two connecting ribsare fixedly connected; conductive screws are in threaded connection to the tops of the connecting ribs; the upper ends of the conductive screws are connected to a conductive beam; a gas collecting hood is fixed between the connecting ribs and the conductive screws; the lower edge of the gas collecting hood is hermetically connected with an isolation film; the size of the isolation film is matchedwith that of the frame-shaped anode; the frame-shaped anode is completely wrapped in a confined space defined by the gas collecting hood and the isolation film; and an acid mist outlet is formed in one side of the gas collecting hood. The insoluble frame-shaped anode structure solves the problems that in the prior art, the energized operation condition of a groove surface cannot be observed through the integrated groove surface sealing gas collecting hood, the short circuit condition cannot be checked in time to easily cause a fire, and a whole cathode must be hoisted when being existing froma groove, so that the operation is cumbersome, and the labor intensity of workers is high.

Description

technical field [0001] The invention belongs to the technical field of hydrometallurgy electrowinning, and in particular relates to an insoluble frame-shaped anode structure capable of collecting acid mist. Background technique [0002] In the hydrometallurgical process of non-ferrous metals such as zinc, copper, nickel, cobalt and manganese, lead alloy anodes or graphite anodes have been used for many years. In sulfate systems, lead alloy anodes are cheap, easy to form, and strong in self-repair. It is widely used, but it also has problems such as low mechanical strength, easy deformation, short service life, and serious anode lead slime. In the chloride system, graphite anode materials were often used in the past. Graphite anodes have high resistance, high power consumption, low strength, easy loss, short working life, and polluted cathode products. It is difficult to obtain high-purity cathode products. Titanium-based metal oxide anode (DSA) uses industrially pure titani...

Problems solved by technology

[0004] The purpose of the present invention is to provide an insoluble frame-shaped anode structure that can collect acid mist, so as to solve the problem that the current integrated tank surface sealing gas collecting cover cannot observe the energized operation of the tank surface, and cannot timely check the short circuit situation, which is easy to cause fire. And the cathode must be hoisted as a whole when it comes out of the tank, resulting in cumbersome operations and high labor intensity for workers.
