Abstract
The utility model discloses a continuous preheater used for producing the brown alumina, comprising an oven body with a material inlet, a material outlet the and a heat insulating layer. The material outlet is positioned on the bottom of the oven body; an annulus wind supply port is arranged around the inner circumference on the inner lower wall of the oven body and is communicated with the oven body inner chamber through the evenly arranged wind supply ports on the annulus wall; a through hole communicated with the wind supply path is positioned on the oven body outer wall corresponding to the wind supply port; the through hole is closed via the valve plate. When in the use, the incendiary spark is positioned in the lower part of the annulus wind supply path inside the oven body, the proportional mixed bauxite and coal are put into the upper part of the annulus wind supply path, the incendiary spark is ignited, the blower is used to deliver the wind into the oven through the annulus wind supply path, the bauxite mixed coal is burned to pre-heat the bauxite, thereby enabling continuous pre-heating to the bauxite and reduction of the production cost of the brown alumina.
Description
Technical field:
The utility model relates to a kind of preheating furnace, especially relates to the continous way preheating furnace that is used to produce brown corundum.
Background technology:
The production process of present brown corundum is the bauxite of fragmentation, coal, iron filings to be mixed the back in proportion throw under the normal temperature and be warmed up to 2050 ℃ in the electric arc furnaces and smelt and produce brown corundum.Above-mentioned production overall process all is electrical heating, and this is with regard to making that the production process power consumption is higher and improved the production cost of brown corundum.If carry out preheating earlier with cheap coal before the bauxite that will mix in proportion, coal are smelted in rendering to electric arc furnaces, then can reduce the production cost of brown corundum, but also not have the preheating furnace of this special use at present.
The utility model content:
The purpose of the utility model is to provide a kind of preheating furnace that is used to produce brown corundum at above-mentioned existing in prior technology deficiency.
For achieving the above object, the utility model can be achieved through the following technical solutions:
The utility model comprises the body of heater that has charging and discharging mouth and heat-insulation layer, and described discharging opening is arranged on bottom of furnace body; Be provided with annular air supply channel in the inboard wall of furnace body upper edge inner circumferential surface that is positioned at the bottom; Described annular air supply channel is by uniform air outlet and the body of heater intracavity inter-connection that is opened on its ring wall; On furnace body outer wall, offer the through hole that is connected with air-supply passage corresponding to described location of air supply inlet place; Described through hole seals by valve plate.
For convenient charging, be hinged with a feed hopper in described body of heater charging aperture position.
Described air-supply passage is connected with blower outlet by any one described through hole.
Advantage of the present utility model is to be arranged on the annular air supply channel along the inner circumferential surface setting of described inboard wall of furnace body bottom, and is opened in the air outlet on its ring wall.During use, ignition substance is placed the bottom of annular air supply channel in the described body of heater, with the bauxite that mixes in proportion, the top that coal is rendered to annular air supply channel, light ignition substance, in stove, blow by annular air supply channel with air blast, the coal that will mix with bauxite is lighted the bauxite preheating, bauxite after the preheating is discharged from discharging opening, in stove, add the mixture of bauxite, coal simultaneously by feed hopper, thereby realize continuous preheating, reach the purpose that reduces brown corundum production cost bauxite.
Description of drawings:
Fig. 1 is a front view of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment:
As shown in the figure, the utility model comprises the body of heater 3 that has charging and discharging mouth 1,2 and heat-insulation layer, and described discharging opening 2 is arranged on body of heater 3 bottoms; Be provided with annular air supply channel 4 in the body of heater 3 inwall upper edge inner circumferential surface that are positioned at the bottom; Described annular air supply channel 4 is by the uniform air outlet 5 and body of heater 3 intracavity inter-connections that is opened on its ring wall; Offer the through hole 6 that communicates with air-supply passage 4 corresponding to described air outlet 5 positions on body of heater 3 outer walls, described through hole 6 is by valve plate 7 sealings, when air outlet 5 by stove in material when stopping up, can dredge by through hole 6.For convenient charging, be hinged with a feed hopper 8 in body of heater 3 charging apertures 1 position.Described air-supply passage 4 is connected with air blast 9 air outlets by any through hole 6, to air blast in the stove.
