Abstract
The invention relates to an electric rotary calcining kiln, which comprises a feeding inlet, heat insulation cotton, a kiln body, a tail gas outlet flue, a sealed material cabin, a hopper, a high-temperature heating region, a medium-temperature heating region and a low-temperature heating region, wherein the feeding inlet is positioned at one end of the kiln body, and the other end of the kiln body is a sealed material cabin; the outside of the rotary kiln is provided with the heat insulation cotton; the high-temperature heating region, the medium-temperature heating region and the low-temperature heating region are sequentially distributed at the bottom of the kiln body and respectively adopt heating wires for heating; the tail gas outlet flue is arranged on the top of the sealed material cabin; the bottom of the sealed material cabin is provided with the hopper. The electric rotary calcining kiln has the advantages that the traditional coal-fired static calcining is changed into electric rotary calcining, the rotating speed, the temperature and the discharging can be respectively and precisely controlled, and the calcining slag particles are uniform; the selenium recovery rate can reach more than 98 percent; the sealed production is realized; the environment is protected.
Description
Technical field
The present invention relates to a kind of copper anode electricity revolution roasting kiln, belong to Copper fabrication technical field of comprehensive utilization.
Background technology
A large amount of copper anode muds can be left in Copper fabrication process, wherein containing precious metal gold and silver etc., in order to fully utilize raising Business Economic Benefit, precious metal is extracted very necessary from the anode sludge, roasting must be carried out by antianode mud before point copper extracts precious metal processing step, first extract selenium (se), and then point copper extracts the precious metals such as gold and silver.Carrying out roasting to copper anode mud is in the past be that fuel static state carries out roasting with coal, and energy consumption is high, and selenium reclaims from low, and only have about 80%, the slag particle of roasting is also uneven, and burning coal pollutes the environment.
Summary of the invention
The object of the invention is to provide a kind of electricity revolution roasting kiln for the deficiencies in the prior art.
Electricity revolution roasting kiln structure of the present invention comprises: feeding import, insulating cotton, kiln body, offgas outlet flue, airtight feed bin, hopper, heat district, middle temperature heating zone, low-temperature heat district;
Feeding import is in kiln body one, and other end is airtight feed bin, and rotary kiln external body is equipped with insulating cotton, distribute bottom kiln body heat district, middle temperature heating zone and low-temperature heat district successively, by electric-heating-wire-heating, offgas outlet flue is arranged at airtight feed bin top, and bottom is hopper.
Beneficial effect of the present invention: change electricity revolution roasting into by the static roasting of traditional burning coal, rotating speed, temperature, blanking all can accurately control, fired slags uniform particles; Selenium recovery can reach more than 98%, airtight production, environmental protection.
Accompanying drawing explanation
Fig. 1 is electricity revolution roasting kiln structural representation of the present invention;
In figure: 1. feeding import, 2. insulating cotton, 3. kiln body, 4. offgas outlet flue, 5. airtight feed bin, 6. hopper, 7. heat district, 8. in warm heating zone, 9. low-temperature heat district.
Embodiment
