Novel sandwich electrolytic manganese anode plate and fabrication method thereof

Abstract

The invention discloses a novel sandwich electrolytic manganese anode plate and a fabrication method for the novel sandwich electrolytic manganese anode plate. The novel sandwich electrolytic manganese anode plate is characterized by comprising an anode conducting beam (2), a lead alloy anode main plate (5) and a conducting copper row (6), the lead alloy anode main plate (5) and the anode conducting beam (2) are formed by integrated pouring casting, the lead alloy anode main plate (5) internally contains a sandwich copper plate (8) with the thickness being 2-3 mm, the sandwich copper plate (8)and the conducting copper row (6) are welded together to form a whole, the sandwich copper plate (8), the conducting copper row (6) and a welding mouth (7) are entirely buried in the lead alloy anodemain plate (5), the middle of the position between the anode conducting beam (2) and the lead alloy anode main plate (5) is provided with a through hole which is taken as a hoisting hole (3), and thelead alloy anode main plate (5) is provided with a plurality of square holes which are taken as circulating holes (1). The novel sandwich electrolytic manganese anode plate is light in weight and high in conductivity and mechanical strength, and by means of the novel sandwich electrolytic manganese anode plate and the fabrication method for the novel sandwich electrolytic manganese anode plate, the electrolytic effect and electrolytic efficiency can be greatly improved.

Description

technical field [0001] The invention relates to an anode plate for electrolysis, in particular to a novel sandwich electrolytic manganese anode plate and a manufacturing method thereof. Background technique [0002] Anode plate is an important tool in the production process of electrolytic manganese, electrolytic zinc and other industries. It is mainly composed of lead-calcium, aluminum, silver, and tin mixed in a certain proportion, and a small amount of rare earth elements are added. It is made by melting, mixing, casting, cold pressing, shearing, and stamping. Its thickness is usually 7mm-10mm, and it has good anti-corrosion performance. . The existing anode plate is mainly composed of the transition section of the conductive beam and the main board welded. There are many dross in the welding area, the conductivity is poor, and the corrosion is fast. It is easy to crack during use, resulting in a sharp drop in conductivity. Then it starts to deform and fall off, causing...

Problems solved by technology

The existing anode plate is mainly composed of the transition section of the conductive beam and the main board welded. There are many dross in the welding area, the conductivity is poor, and the corrosion is fast. It is easy to crack during use, resulting in a sharp drop in conductivity. Then it starts to deform and fall off, resulting in burnt plate and failure, shorter life

See image 3 , the traditional anode plate has a welding zone, that is, between the transition zone and the main board, the welding zone has low strength and low conductivity, and is the weakest link of the anode plate
