Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anode straightening device used when refining metals by electrolysis.

The electrolytic refining method for metals, such as copper, involves alternatingly suspending a high-purity seed plate as a cathode plate and an anode made of blister copper as an anode plate in an electrolytic tank filled with electrolyte, and energizing them. In order to improve operational efficiency, as many seed plates and anodes as possible are suspended in the electrolytic cell in close proximity to each other.

Therefore, the flatness and parallelism of each electrode plate, that is, the seed plate and the anode, are important factors in order to prevent short circuits between the electrode plates and improve electrolysis efficiency.

On the other hand, the only part of each electrode plate that is used for electrolysis is the part that is immersed in the electrolyte, so the other parts, that is, the parts that are used for suspension, form that part. It is shaped so that it requires as little material as possible.

Considering these matters regarding the anode, as shown in FIG. It is molded thinner than part 2.

The anode 1 having such a shape is generally cast using a horizontal open mold, but for this purpose there is a draft angle T on the peripheral edge of the product.
are formed, and there are distortions and threads in each part.

Furthermore, the ears 3 and 4 may be deformed during handling such as transportation.

Therefore, when the casting is completed, the anode 1 has poor flatness.
In addition, the draft T formed at the lower edge of the ears 3 and 4 and the ears 3
, 4, etc., it is not possible to obtain the necessary parallelism by hanging vertically in the electrolytic cell, and there is a risk of short circuit with the adjacent seed plate.

Therefore, in order to eliminate this risk, it is necessary to straighten the parts 2, 3, 4 before suspending the anode 1 in the electrolytic cell.

The straightening devices conventionally used to perform this straightening are those that flatten the entire surface of the anode transported by an appropriate means using a hydraulic cylinder, or straighten the anode by flattening the body and ears of the anode. This involves hitting multiple points on almost the entire surface with an air hammer to flatten the surface.

However, in reality, the required flatness can be obtained without pressing the entire surface of the anode, and the desired flatness can be obtained without using a conventional large-sized, high-power straightening device to press the entire surface. can be corrected.

The same applies when hitting multiple points on almost the entire surface of the anode with an air hammer.Furthermore, when an air hammer is used, it generates significant noise, which has the disadvantage of deteriorating the working environment.

In addition, the ears are formed thinner than the body,
Since this ear part serves to suspend the anode vertically, its lower surface needs to be corrected horizontally.

Therefore, it is advantageous in terms of work to correct the ears separately from the body.

The present invention was made in view of the above circumstances, and aims to perform appropriate correction with a small amount of power.The present invention is characterized by flat correction by pressing flat at multiple locations on the front of the torso. At the same time, the front and upper surfaces of the ears are pressed to perform flat correction and horizontal correction.
