Embodiment 1

[0026] This embodiment provides a post-treatment method for suppressing a particulate copper anode produced, comprising the steps of:

[0027] (1) Put the particulate copper anode into the vibrating polishing machine, add water to moisturize, then add the weight ratio of 1: 1 mixed alkyl sulfonate and sodium alkylbenzene sulfonate as a weak alkaline surfactant. The weight ratio of the particulate copper anode and the weakly alkali surfactant is 2400: 1. The vibration polishing machine is opened for 7 minutes, and the surface oil is removed, and the water is continuously flushed, rinsed into the oil-free non-foam, add 3-hydroxy-3- Carboxyxhaldic acid washing, the weight ratio of the particulate copper anode and 3-hydroxy-3-carboxylicenic acid is 2200: 1, and the vibration polishing is removed from the oxide, and finally the water is flushed to the copper anode surface light;

[0028] (2) Put the particulate copper in the step (1) into the vibrating centrifugal dewatering machine, t...

Embodiment 2

[0033] This embodiment provides a post-treatment method for suppressing a particulate copper anode produced, comprising the steps of:

[0034] (1) Put the particulate copper anode into the vibration polishing machine, add water to moisturize, then add a weak alkaline surfactant-alkylbenzene sulfonate, the weight ratio of the particulate copper anode and the weak baseive surfactant is 2500: 1, open the vibration polishing machine vibration polishing 8 minutes, remove the surface oil, continue to increase the water, rinse to the oil-free non-foam, add alkyl polysaccharide and 3-hydroxy-3-carboxylatonic acid mix (w: w = 1: 1) Weak acidic cleaning agent, weight ratio of particulate copper anode and weak acid cleaning agent is 2000: 1, vibration polishing 7min removal of oxidized skin, and finally continuously adding water to the copper anode surface light bright;

[0035] (2) Put the particulate copper in the step (1) into the vibrating centrifugal dewatering machine, then the particl...

Embodiment 3

[0040] This embodiment provides a post-treatment method for suppressing a particulate copper anode produced, comprising the steps of:

[0041] (1) Put the particulate copper anode into the vibration polishing machine, add water to moist and wet, then add a weak alkaline surfactant-alkyl sulfonate, the weight ratio of the particulate copper anode and sodium alkyl sulfonate is 2600: 1. Open the vibration polishing machine vibration and polishing 10 minutes, remove the surface oil, continue to increase the water, rinse to the oil-free non-foam, and add alkyl polysaccharide and 3-hydroxy-3-carboxylic acid (w: w = 1: 1) Mixed weak acidic cleaning agent, the weight ratio of the particulate copper anode and the weak acid cleaning agent is 2000: 1, and the vibration polishing is removed from the oxidized skin, and finally the water is flushing to the copper anode surface light;

[0042] (2) Put the particulate copper in the step (1) into the vibrating centrifugal dewatering machine, then ...

Abstract

The invention discloses a post-treatment method of a granular copper anode produced by pressing. The post-treatment method comprises a cleaning process and a drying process, the cleaning process adopts a cleaning mode of combining a weak base cleaning agent and a weak acid cleaning agent to clean the copper anode, so that the amount of sodium hydroxide used by a wastewater treatment system is reduced by 80%, and the effects of reducing cost and improving efficiency are achieved; and a fiber drying agent adopted in the drying process belongs to a drying agent with high hygroscopicity, environmental friendliness and safety, the use effect is good, the surface quality of the product is not affected, the energy consumption in the drying process is low, the drying efficiency is high, and the quality problems of surface yellow spots, black spots and the like caused by drying the copper anode through a traditional drying method are solved.

Description

Technical field [0001] The present invention relates to a copper anode-rear treatment method, and more particularly to a post-treatment method of pressing the production of particulate copper anodes. Background technique [0002] The particulate copper anode surface of the suppression process is stained with a layer of lubricating oil film, and there is a layer of oxide layer varying degrees, and therefore, the particulate copper anode is required to be cleaned and dried. [0003] At present, the industry has a weaker acidic tea seed powder to add citric acid as a cleaning agent, and the cleaning surface contains oil-containing layer. When cleaning, use multiple additional methods, each time the cleaning is used, and the surface is used to dry the surface. Continue to invest, the amount of each investment is reduced, of which the tea seed powder is strong, and its weak acid has a certain degraded layer ability, and citric acid mainly removes the oxide layer. The method exists: on...
