Description
Technical field
The present invention relates to nonferrous metallurgy field more particularly to a kind of energy-saving rotary kilns.
Background technique
Under normal circumstances, in order to effectively regenerate and recycle the Induction refining of chemical field, needing will be organic in Induction refining
The substances such as matter, coking carry out burning disposal, and burning disposal is entire waste catalyst regneration and one extremely crucial in removal process
Processing links, and shorten the return period of valuable metal, improve an important step of valuable metal recovery efficiency.It is most of
Later separation, refining process containing valuable metal materials are required to first effectively be burnt the waste material containing valuable metal
It burns to remove organic matter in material, so that the valuable metal contained by it be made effectively to be leached, be separated, obtains pure valuable gold
Belong to.It is more stable in view of the performances such as organic matter, coking in Induction refining, there is very strong burning inertia, seriously constrain subsequent
Treatment effeciency.Therefore, the firing efficiency for improving Induction refining, regeneration to Induction refining and the wherein recycling of valuable metal have weight
The meaning wanted.
In recent years, due to the shortage of domestic Precious Metals Resources and the increase of dosage, people increasingly pay attention to returning from waste material
The efficiency of valuable metal is received, but the Ore Leaching of valuable metal can be hampered to some extent containing the organic matter in valuable scrap metal
And refining process, therefore many people have carried out a large amount of research to the burning facility of valuable metal waste material.Currently associated burning is set
Standby includes reverberatory furnace, pellet type pyrolysis oven and rotary kiln.Process flow is long when reverberatory furnace burns, and valuable metal dispersion is serious, has
The rate of recovery of valence metal is low, and environmental pollution is serious；The pyrolysis oven of pellet type burns higher cost, and labor intensity is larger, and material is
Static state is burned, and the burning time is long, and production efficiency is low.
Application No. is 201510453626.2 to disclose a kind of " rotary kiln ", including tilting being driven in mounting base by revolution

House dust natural subsidence is burnt, the generation of dust in kiln body is reduced.
Wherein, blower is provided between the air outlet and the second air inlet.
The setting of blower is accelerated to go out airspeed in combustion chamber, and a large amount of hot wind enters in kiln cylinder, and material burning ground is more
Sufficiently.
Wherein, be provided with backwind tube in the kiln cylinder, the arrival end of the backwind tube closely after at kiln lid, the backwind tube is worn
Kiln discharge cylinder, nearby at kiln lid, the backwind tube connects the first air inlet of combustion chamber by blast pipe for outlet end.
Backwind tube is set in kiln cylinder, and the hot wind of backwind tube discharge comes back to combustion chamber and heated, for kiln cylinder
Secondary use；Combustion chamber is connect with kiln cylinder by backwind tube, backwind tube, combustion chamber, kiln cylinder constitute enclosed system, reduce heat
Loss, while the emission-free discharge of kiln cylinder reduces pollution on the environment.
Wherein, deduster is provided between the outlet end and blast pipe of the backwind tube.
The hot wind of backwind tube recycling is dusted processing by deduster, increases the collection efficiency for burning dust, avoids
Dust accumulation influences outlet air.
Wherein, temperature sensor and pressure sensor are provided on the kiln cylinder.
Temperature sensor, pressure sensor carry out temperature and pressure monitoring to kiln cylinder respectively, guarantee the normal use of kiln cylinder,
It avoids temperature, pressure from not reaching requirement, influences efficiency of combustion, or even damage is brought to kiln cylinder.
Wherein, a plurality of prismatic protrusions are set side by side on the lifting blade.
During lifting blade raises material in kiln cylinder, material collides with prismatic protrusion, and prismatic protrusion is to object
Material generate cutting, material dispersion it is more uniform.
Wherein, dispenser is set on the outside of the kiln body, the dispenser connects feed inlet by feed pipe.
Preferably, the dispenser is rotary dispenser.
Compared with prior art, the present invention realize the utility model has the advantages that kiln cylinder is horizontally arranged by energy-saving rotary kiln of the present invention,
The occupied space of kiln cylinder is reduced, meanwhile, it is provided with lifting blade in kiln cylinder, so that material is full of entire kiln cylinder, material burns more
Completely, the rate of recovery of valuable metal is improved；Combuster, combustion chamber is arranged in kiln cylinder outside upright in energy-saving rotary kiln of the present invention
It is vertically arranged, convenient for the natural subsidence of dust；Backwind tube, the import of backwind tube is arranged in energy-saving rotary kiln of the present invention in kiln cylinder
