Abstract
The utility model discloses a kind of high purity magnesium roaster, including furnace body, preheating zone, roast area and cooling zone are followed successively by furnace body from top to bottom, spiral helicine material flow path is set in the roast area, the furnace body setting carbon dioxide venthole of roast area is connected to carbon dioxide collection chamber；Setting recycling plate at the material outlet of cooling zone, also sets up cold wind import, and gas via-hole is arranged with roasting section in the cooling zone.The utility model has the advantages that：Since material channel is arranged in the oblique upper of heating zone, the efficiency of heating surface is high, and due to being helical form, same difference in height, and the time of contact of material and heating zone is longer, and therefore, the temperature of heating zone can be reduced suitably, reduce the heat resistant requirements of furnace body, reduce cost.
Description
Technical field
The utility model is related to the preparation facilities of high purity magnesium, specifically a kind of roaster.
Background technology
It is mainly produced using two one-step baking methods in highly-purity magnesite industrial production, first by magnesite lump ore (grain size 150mm
~300mm) it is heated to 1000 DEG C~1200 DEG C and prepares light calcined magnesia, it is then levigate, send high temperature after high-pressure dry process pressure ball health
Shaft furnace is in 1700 DEG C~1850 DEG C baked for producing highly-purity magnesites (MgO >=97.5%).Chinese invention application number 02275402.4 is public
A kind of roaster is opened, which is arranged alternate heating zone and material channel, and the material channel is vertical, such knot
Structure determines that material will reach higher temperature, since material is not in the top of heating zone, but side, therefore, the efficiency of heating surface
It is low；Further, since heating time is shorter, it is therefore desirable to Heating Zone Temperature it is higher, this requirement to furnace body is naturally very high, one
As be difficult to realize.
Invention content
In order to solve the above technical problems, the purpose of this utility model is to disclose a kind of efficiency of heating surface height, and heated time is long
Roaster, specific technical solution is as follows：
A kind of high purity magnesium roaster, including furnace body are followed successively by preheating zone, roast area and cooling zone in furnace body from top to bottom,
Spiral helicine material flow path, the furnace body setting carbon dioxide venthole and carbon dioxide collection of roast area are set in the roast area
Chamber is connected to；Setting recycling plate at the material outlet of cooling zone, also sets up cold wind import, and gas is arranged with roasting section in the cooling zone
Body through-hole.
The material flow path is multigroup, is arranged parallel to each other.
The utility model has the advantages that：Since material channel is arranged in the oblique upper of heating zone, the efficiency of heating surface is high, and due to
It is helical form, the time of contact of same difference in height, material and heating zone is longer, and therefore, the temperature of heating zone can be reduced suitably,
The heat resistant requirements for reducing furnace body, reduce cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Illustrate the utility model below in conjunction with the accompanying drawings, as shown, the utility model includes furnace body 1, in furnace body 1 from
It is followed successively by preheating zone 2, roast area 3 and cooling zone 4 under, spiral helicine material flow path 5, roasting are set in the roast area 3
The furnace body setting carbon dioxide venthole 6 in area is connected to carbon dioxide collection chamber 7；Recycling is set at the material outlet 8 of cooling zone
Plate 9, also sets up cold wind import 10, and gas via-hole 11 is arranged with roasting section in the cooling zone.
The material flow path is multigroup, is arranged parallel to each other.
Claims (2)
1. a kind of high purity magnesium roaster, it is characterised in that：Including furnace body, preheating zone, roast area are followed successively by furnace body from top to bottom
And carbon dioxide venthole and two is arranged in cooling zone, the furnace body of the spiral helicine material flow path of setting in the roast area, roast area
