Description
Technical field
The utility model relates to germanium mine field of smelting, and in particular to a kind of electric heating rotary kiln for germanium concentrate calcination.
Background technique
Germanium tannin slag also accounts for about between the 20-30% of total amount containing a large amount of organic matter after being dehydrated.This slag charge is not
It can be directly used in germanium metallurgy chlorinated distillation technique, the impurity such as organic matter need to be removed as much as possible, most efficient method is exactly to increase
Wen Rangqi burning, organic matter generate carbon dioxide and volatilize away.Traditional heating mode is that slag charge is put into rotary kiln or combustion
Burn heating burning in lower part in disk, three warm areas of rotary kiln point；Preheating zone, heating zone, combustion zone, temperature are respectively 150 DEG C, 300-
400 DEG C, 600-700 DEG C use coal or electric energy sealed thermal insulating heating method.But since Temperature Distribution is larger, and in preheating zone
Since temperature is lower, germanium oxide is easy to generate tetragonal structure molecular structure, and low temperature is gradually increased to high temperature, makes entire rotary kiln
Production capacity reduces.
Utility model content
It can be improved germanium concentrate calcination quality the utility model proposes one kind and promote production capacity, reduce equipment damage rate
Electric heating rotary kiln.
To achieve the goals above, the utility model is achieved through the following technical solutions:
A kind of electric heating rotary kiln for germanium concentrate calcination includes the kiln body of inclination installation, the kiln body both ends difference
For feed end and discharge end, the kiln body is successively arranged preheating zone and combustion zone from feed end to discharge end, the preheating zone
It is equipped with the first insulating layer on the outside of kiln body, is equipped with the second insulating layer, second insulating layer and kiln on the outside of the kiln body of the combustion zone
Cooling layer is equipped between body, the insulating layer is externally provided with cooling vent, and the cooling vent is connected to the cooling layer, the combustion zone
Equipped with retaining ring, the retaining ring is distributed in the kiln body inner annular.
Further, the kiln body tilts 2-4 ° along discharge end from feed end.
Further, support roller station is equipped on the outside of the kiln body.
Further, there are two the support roller station is set, between one of support roller station setting preheating zone and combustion zone,
Another support roller station is located at discharge end.
Further, the cooling vent is externally connected with air-cooler.
Further, the cooling vent at least two.
Further, the retaining ring is at least three.
Further, the height of the retaining ring is 0.1-0.15 times of the kiln body diameter.
The utility model is used for the electric heating rotary kiln of germanium concentrate calcination, the beneficial effect is that:
(1) it is provided with three-level retaining ring, the material to have burnt is overturn through rotary kiln to float on the surface into next retaining ring, a small number of
The delay of incomplete combustion burns away in situ, can thoroughly remove organic matter, improves germanium concentrate calcination quality.
(2) combustion zone has additional cooling vent on the outside of kiln body, prevents the kiln body temperature to be more than 880 DEG C and cause spontaneous combustion；
Prevent apparatus overheat from damaging.
(3) it is equipped with preheating zone and two kinds of combustion zone warm area, combustion zone is directly entered behind the preheated area of slag charge and increases burning
Time, production capacity greatly improve；
(4) combustion zone temperature can reach 800 DEG C or more, prevents germanium oxide in material from generating tetragonal structure molecular structure, mentions
High burning quality.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model；
1 kiln body, 2 feed ends, 3 discharge ends, 4 preheating zones, 5 combustion zones, 6 first insulating layers, 7 second insulating layers, 8 is cooling
Layer, 9 cooling vents, 10 retaining rings, 11 support roller stations.
Specific embodiment
Combined with specific embodiments below and attached drawing is further described the utility model.
A kind of electric heating rotary kiln for germanium concentrate calcination, as shown in Figure 1, including the kiln body 1 of inclination installation, kiln body 1
Both ends are respectively feed end 2 and discharge end 3, and kiln body 1 tilts 2-4 ° along discharge end 3 from feed end 2, and kiln body 1 is from feed end 2 to out
Material end 3 is successively arranged preheating zone 4 and combustion zone 5, is equipped with the first insulating layer 6, the kiln body of combustion zone 5 on the outside of the kiln body 1 of preheating zone 4
