Abstract

The invention relates to a device for collecting anode slime from the bottom of an electrolytic cell in a zinc electrolytic refining process. The device mainly comprises an electrolytic cell body and two vacuum sucking devices, wherein the bottom of the electrolytic cell is trapezoidal, an anode slime gathering device is arranged at the bottom of the electrolytic cell body, and two ends of the electrolytic cell body are provided with transmission mechanisms; the anode slime gathering device is connected to the transmission mechanisms through a corrosion-resistant drag rope; the vacuum sucking devices are arranged at two sides of the electrolytic cell body; vacuum sucking pipes in the vacuum sucking devices are inserted into the bottom end of the electrolytic cell body, and the vacuum sucking pipes suck the anode slime through a vacuum pump. The device has the following beneficial effects that the device is easy to operate and is liable to the realization of industrialized application, the stability in operation is good, not only is the on-line sucking of the anode slime realized, but also the sucking rate of the anode slime is greatly improved, and furthermore, the anode slime is prevented from accumulating.

Description

technical field [0001] The invention relates to the field of zinc electrolysis, in particular to a device for collecting anode slime at the bottom of an electrolytic tank in a zinc electrolytic refining process. Background technique [0002] At present, 80% of zinc in the world is produced by hydrometallurgical process. The final process of zinc wet extraction process is zinc electrolytic deposition, that is, zinc is precipitated from zinc sulfate solution to the cathode, and then cast into zinc ingot products. In the zinc electrowinning process, in order to prolong the life of the lead alloy anode, a certain amount of manganese ions are added to the electrolyte, and these manganese ions are easily oxidized to manganese dioxide on the anode to form anode slime. At the same time, there are certain impurity ions in the electrolyte, such as calcium, aluminum, magnesium, silicon, etc., and these ions will also form crystalline precipitates in the form of compound salts, which ar...
