Machine for gathering discrete metal from smelting slags

Abstract

The invention discloses a machine for gathering discrete metal from smelting slags, which comprises a rack, an electric control cabinet, a driving part and a plate surface rubbing, extruding and grinding mechanism, wherein the driving part is electrically connected with the electric control cabinet; the plate surface rubbing, extruding and grinding mechanism is arranged on the rack and mainly comprises a reciprocating rubbing plate and a reverse rubbing support plate, wherein the reciprocating rubbing plate and the reverse rubbing support plate extend along the longitudinal direction of the rack and are oppositely arranged at the left and right sides of the rack; the reciprocating rubbing plate is linked with the driving part; the reverse rubbing support plate is fixed on the rack; opposite surfaces of the reciprocating rubbing plate and the reverse rubbing support plate are reverse rubbing surfaces; feeding holes are formed over the two reverse rubbing surfaces; and discharging holes are formed under the two reverse rubbing surfaces. By adopting the machine, discrete metal in nonferrous smelting slags can be gathered and extracted effectively and converged together to fulfill the aims of saving energy and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal smelting tailings treatment, in particular to a discrete metal gathering machine for smelting tailings. Background technique [0002] The tailing slag after smelting non-ferrous metals basically contains many metals with fine grains, the metal content of these slags is about 10%-20%, and the metal content can reach up to 30%. According to statistics from relevant departments, the amount of non-ferrous metal tailings accumulated in the domestic smelting industry alone amounts to hundreds of millions of tons. Except for a small amount of recycling, most of them are still buried for a long time, resulting in a serious waste of resources. , has caused great losses to the resource recycling of our country. [0003] In order to reduce the loss and waste of resources, various enterprises across the country have been taking various measures to extract metals from their tailings for a long time....

AI Technical Summary

Problems solved by technology

For example, using various chemical reagents to dissolve, but the dosage is high, the cost is high, the oxidation is fast, the toxicity is high, the extraction types are few, and the harm to humans, animals and the environment is serious; another example is to use a rotary kiln for calcination, but this method requires a large investment and a long cycle. , high energy consumption, large waste gas, less extraction volume, and poor efficiency; another example is extraction with related metallurgical machinery and mineral processing equipment, which also involves more investment, less income, poor sewage discharge, large loss, difficult adaptation, and low efficiency; or extraction with water filtration , but also because of high water consumption, less metals, high consumption, extensive soil and water pollution, and serious damage to animals and plants; another example is the use of ancient simple furnaces for refining, but due to poor facilities, poor technology, lack of craftsmanship, and high consumption, it is obtained. less benefit, more serious pollution

All of the above methods cannot fully extract the high content of metals in the tailings, and the loss and waste continue
