Description

Technical Field

[0001] The invention relates to the technical field of anode plate production and manufacturing, in particular to a new type of anode plate for electrolytic manganese. Background Art

[0002] Traditional anode plates are made of smelting lead-silver alloy. The manufacturing process is as follows: alloy melt is made - conductive copper rods wrap the alloy melt and cast it into a handle, the lead-silver alloy melt is cast into a grid, and after the grid is stamped into shape, the handle and the grid are connected together by friction welding to form a lead-silver alloy anode plate. There are problems such as complex manufacturing process, low life, high cost, and heavy weight. More importantly, traditional lead-silver alloy anode plates, when the lead-silver alloy anode plates are inserted into the anode liquid for reaction, will introduce heavy metal ions in the lead-silver alloy anode plates into the anode liquid, firstly, causing the anode plates to corrode, become thinner, and break; secondly, heavy metals are added to the anode liquid, and the anode liquid reuse effect is poor. After the lead-silver alloy anode plates are corroded, the anode slag under the electrolytic cell increases and carries heavy metal ions.

[0003] In order to solve the above problems, increase the service life of the anode plate and improve the anode liquid recycling effect, the present application is proposed. Summary of the invention

[0016] See also Figures 1 to 4In an embodiment of the present invention, a novel anode plate for electrolytic manganese metal comprises a conductive copper rod 1 and a good conductor sheet 3. The conductive copper rod 1 is installed on the outside of the good conductor sheet 3. A copper strip protective sleeve 2 located on the outside of the conductive copper rod 1 is arranged on the top of the good conductor sheet 3 to protect the connection. The conductive copper rod 1 and the outside of the good conductor sheet are coated with plastic. The coating material is a conductive plastic 6. The conductive plastic 6 is introduced and attached to the surface of the good conductor sheet 3. It will not dissolve in the anode liquid, so that the heavy metals in the anode liquid are completely eliminated, and the amount of anode slag is also reduced. In particular, it is easy to obtain a conductive plastic with a thermal expansion coefficient similar to that of the good conductor sheet 3, and the conductive plastic has good elasticity and will not produce staggered layers. Even if it is elastically bent, no cracks will appear, so that the service life of the anode plate is increased. The conductive plastic 6 can be processed on the surface of the good conductor sheet 3 by hot melt injection molding or the like. The processing is convenient, the uniformity is high, and no secondary processing is required, which saves costs. The conductive plastic 6 can be repaired by spraying if it is damaged, and can be removed by hot melt and then coated again if it is seriously damaged, which has repeatability.

[0017] In a preferred embodiment, evenly distributed combining holes are provided on the good conductor sheet. The conductive plastics 6 on both sides of the good conductor sheet are connected together in the combining holes 5 by injection molding of the combining holes 5 and the conductive plastics 6, which can effectively prevent the conductive plastics 6 from separating from the good conductor sheet 3 and improve the service life.

[0018] In a preferred embodiment, the good conductor sheet 3 is provided with evenly distributed liquid guide holes 4, and the inner wall of the liquid guide holes 4 is covered with 6 layers of conductive plastic, which can completely prevent the good conductor sheet 3 from contacting the anode liquid, thereby playing a good protective role and improving the service life.

[0019] In a preferred embodiment, the thickness of the conductive plastic 6 is 2.5 mm ≤ plastic coating thickness ≤ 3 mm. The surface of the good conductor sheet 3 after plastic coating is flat. The thickness of the good conductor sheet 3 is between 7.5 mm and 8 mm. The conductive plastic 6 of the plastic coating part must fit tightly with the good conductor sheet 3 and be uniform and free of bubbles.

[0020] A method for producing a novel anode plate for electrolytic manganese metal comprises the following steps: S1, conductive copper rod 1 is processed to specified specifications; S2, punching, trimming and deburring the good conductor sheet 3 into an anode plate grid template by a stamping machine; S3, the processed anode plate grid template and the conductive copper rod 1 are connected by welding to form an integral anode plate initial plate; S4, using an injection molding machine to coat the conductive plastic 6 on the manufactured integral anode plate initial plate using a plastic processing and molding method; S5, the initial anode plate after plastic coating is cooled to become a new anode plate finished product; S6, the new anode plate finished product is tested for plastic coating integrity, appearance, chemical properties and physical properties, and at least one test performance test is carried out. If it meets the use requirements, it is considered a qualified product.

[0021] In a preferred embodiment, in step S2, the good conductor sheet is punched by a stamping machine to form holes including bonding holes and liquid guide holes. The bonding holes are first punched and then the liquid guide holes are punched. The bonding holes are distributed around the liquid guide holes.

[0022] In a preferred embodiment, the combining holes are evenly distributed in an interlaced manner, with a diameter of 3 mm and a spacing of 20 mm between adjacent holes. The density of the combining holes is increased as much as possible while ensuring the performance of a good conductor sheet. The conductive plastic 6 can be combined together through the combining holes to form a whole. The number of combining holes determines that there are more connection points of the conductive plastic 6 on both sides, and the firmness of the fit is better.

[0023] It should be noted that the above embodiments all belong to the same inventive concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference may be made to the description in other embodiments.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
