Description

Technical Field

[0001] The invention relates to the technical field of ferrous salt storage, in particular to a method for resisting ferrous salt oxidation. Background Art

[0002] Ferrous salts are salts containing ferrous ions, and their salts are also called ferrous salts. When elemental iron undergoes a replacement reaction, the product is a +2 ferrous salt, which has both oxidizing and reducing properties, with the reducing property generally being the dominant one.

[0003] In the prior art, when storing ferrous salts, iron filings and liquid acid are typically added to the storage container to prevent oxidation of the ferrous salt. This allows any ferric iron present to be reduced to ferrous iron by the elemental iron, thus preventing the introduction of other impurities. However, directly adding the iron filings to the ferrous salt storage container makes it difficult to store and collect the iron filings later, thus affecting the purity of the ferrous salt during use.

[0004] Therefore, we need a method for anti-oxidation of ferrous salts to solve the problem that the iron filings left in the existing ferrous salt containers are difficult to recycle, and to effectively recycle the iron filings residues in the containers. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for anti-oxidation of ferrous salts to solve the problem that the iron filings left in the existing ferrous salt container are difficult to recover, and the iron filings residues in the container can be effectively recovered.

The outer ring surface of the rubber clamping ring is fixed to the surface of the installation groove.

[0014] Preferably, a metal mesh is fixed to the inner ring surface of the pressure ring, the bottom surface of the metal mesh and the bottom surface of the pressure ring are coplanar, and a pick-up groove is opened on the inner ring surface of the pressure ring.
