Electrolyte low-position circulating tank capable of removing bubbles

Abstract

The invention discloses an electrolyte low-position circulating tank capable of removing bubbles. The electrolyte low-position circulating tank comprises a shell, and a cover is arranged at the top of the shell; a plurality of electrolyte inlet pipes are arranged at the top of the cover; a first electrolyte degassing plate and a second electrolyte degassing plate are fixedly arranged in the shell, the first electrolyte degassing plate and the second electrolyte degassing plate are both obliquely arranged, and degassing plate flanges are fixedly arranged on the front side and the rear side of the first electrolyte degassing plate and the front side and the rear side of the second electrolyte degassing plate; an electrolyte sedimentation baffle plate is fixedly arranged below the first electrolyte degassing plate, the inner space of the shell is divided into a storage tank and a separation sedimentation tank by the sedimentation baffle plate, an electrolyte circulating port is arranged on the side wall, corresponding to the storage tank, of the shell, and a slag outlet is arranged on the side wall, corresponding to the separation sedimentation tank, of the shell; and a bubble breaking assembly is fixedly arranged on the first electrolyte degassing plate. Bubbles in the electrolyte can be broken, it is guaranteed that copper ions and impurities in the electrolyte are uniform, and therefore a high-quality copper plate can be obtained after electrolytic refining.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal smelting, in particular to an electrolyte low-level circulation tank capable of removing air bubbles. Background technique [0002] In the copper electrolytic refining process, the prepared electrolyte contains air, and the temperature of the electrolyte is between 50 and 60°C. At this temperature, the evaporated water vapor, the original air, and the electrolyte still contain Fe 2+ ,OH - , SO 4 2- Ions, in the state of electrolysis, will decompose into oxygen and escape from the electrolyte, and some of them will form bubbles in the electrolyte and circulate with the electrolyte. This kind of bubble structure is more complex, containing fine dust particles, SO 3 , SO 2 , Fe 2+ , SO 4 2- Impurities such as ions, these impurities and Cu 2+ Smaller than the body, it floats up in the electrolyte, and the density of copper ions floats down, resulting in a large difference in the com...

Problems solved by technology

This method has the advantages that the liquid flow direction is consistent with the anode sludge settlement direction, which is beneficial to the anode sludge settlement, reduces the influence of the anode sludge on the cathode copper, and reduces the loss of gold and silver. However, this method cannot remove the fine dust in the air bubbles, and the air bubbles are not Broken, the dust residue is brought into the electrolyte again, resulting in poor quality of electrolytic copper
