Abstract

The invention belongs to Copper making technical fields, and in particular to a kind of drying means of the decopper(ing) earth of positive pole first pelletizes the decopper(ing) earth of positive pole, then carry out microwave drying.The invention further relates to the drying systems that the decopper(ing) earth of positive pole is dried using above-mentioned drying means, including microwave drying oven, the upstream of the microwave drying oven to be provided with pelletization unit.Using the above scheme, directly microblogging is dry after the granulation of the decopper(ing) earth of positive pole, solves the problems such as fugitive dust in traditional decopper(ing) earth of positive pole drying process, pollution, serious precious metal losses, drying efficiency is high, equipment investment is few, low energy consumption, operating cost is low, substantially increases the production capacity of drying operation.

Description

The drying means and drying system of the decopper(ing) earth of positive pole
Technical field
The invention belongs to rare precious metal technical field of smelting, and in particular to a kind of drying means of the decopper(ing) earth of positive pole and drying System.
Background technique
In copper anode mud pyrometallurgical smelting process for producing technique, copper anode mud need to be dried after leaching decopper(ing) to aqueous Rate can be added in furnace less than 3% side smelts.At present both at home and abroad decopper(ing) earth of positive pole drying means be with it is more have electric dry oven it is dry, The drying of steam blade, steam belt drying etc..The dry feature of electric dry oven is that energy consumption is high, the rate of recovery is low, operating environment is poor;Steam Blade drying is more demanding to decopper(ing) mud, and the aqueous height of material is easily stifled, height containing acid is big to equipment corrosion, bismuth containing arsenic is high easily bonds paddle Leaf, blade need periodic cleaning, soldering, and working service difficulty is at high cost greatly, and the powder after drying, which enters furnace, keeps smelting smoke dust rate high; Steam heating band drier takes up a large area, and requires height to steam stable, steam is using efficiency is low, drying efficiency is low, raw Production capacity power is small.
Summary of the invention
The purpose of the present invention is to provide it is a kind of it is high-efficient, dust is few, requires material physicochemical property low decopper(ing) anode The drying means of mud.
To achieve the above object, the technical solution adopted by the present invention are as follows: a kind of drying means of the decopper(ing) earth of positive pole will first take off Copper anode mud granulation, then carry out microwave drying.
It is done using above-mentioned drying means to what the decopper(ing) earth of positive pole was dried another object of the present invention is to provide a kind of Drying system, equipment is simple, cost input is few, drying efficiency is high.
To achieve the above object, the technical solution adopted by the present invention are as follows: a kind of to use above-mentioned drying means to decopper(ing) anode The upstream of the drying system that mud is dried, including microwave drying oven, the microwave drying oven is provided with pelletization unit.
Using the above scheme, direct microwave drying after the granulation of the decopper(ing) earth of positive pole, it is dried to solve traditional decopper(ing) earth of positive pole The problems such as fugitive dust, pollution in journey, serious precious metal losses, drying efficiency is high, equipment investment is few, low energy consumption, operating cost is low, Substantially increase the production capacity of drying operation.
Detailed description of the invention
Fig. 1 is the schematic diagram of drying system of the invention.
In figure: 10- microwave drying oven, 20- pelletization unit, 21- blender, 22- mud extruder, 23- hopper, 30- conveyer belt, 40- material collecting device.
Specific embodiment
Technical solution of the present invention is described in further detail with reference to the accompanying drawing.
A kind of drying means of the decopper(ing) earth of positive pole, first pelletizes the decopper(ing) earth of positive pole, then carry out microwave drying.
Drying system used in a kind of above-mentioned decopper(ing) earth of positive pole drying means, including microwave drying oven 10, the microwave are dry The upstream of dry case 10 is provided with pelletization unit 20.
Preferably, the drying system further includes conveyer belt 30, and the Pellet exit of pelletization unit 20 closes on setting Above the zone face of 30 upstream of conveyer belt, microwave drying oven 10 is arranged on the transport path of conveyer belt 30.The pelletization unit 20 include blender 21, mud extruder 22 and hopper 23.The downstream of the conveyer belt 30 is equipped with material collecting device 40.In addition, institute It states conveyer belt 30 and uses high temperature resistant, corrosion resistant Teflon band.
Above scheme, after the decopper(ing) earth of positive pole enters hopper 23, stirring keeps its aqueous uniformly, is extruded into greatly through mud extruder 22 Small uniform pellet, and uniformly trickle down on conveyer belt 30;Pellet is delivered to progress microwave drying at microwave drying oven 10, changes The heat source type of decopper(ing) earth of positive pole traditional drying using microwave heating makes decopper(ing) earth of positive pole itself become heater, no The process for needing heat transfer adds according to material particular diameter size, the different adjustment microwave power of moisture content or conveyer belt transmission speed Thermal velocity is fast, the time is short, high-efficient, substantially increases production capacity.Pellet keeps opposing stationary with conveyer belt in whole process, The formation for greatly reducing dust, fugitive dust improves working environment, and pellet is filled through the conveying of conveyer belt by material collection after drying Collection is set, in the process without human intervention, reduces workload, improves work efficiency.
