Abstract
The invention relates to a connecting structure, in particular to a cyclone preheater and roasting furnace connecting structure for roasting aluminum hydroxide in the process of producing aluminum oxide. The cyclone preheater and roasting furnace connecting structure comprises a cyclone preheater and a roasting furnace, wherein a top plate of the cyclone preheater is welded with a first connecting inclined plate; a top plate of the roasting furnace is welded with a second connecting inclined plate; and the first connecting inclined plate and the second connecting inclined plate are connected with each other and positioned on the same plane. The connecting structure has the advantages that: a side plate is used for forcing airflow to flow along the volute-shaped cylinder walls of the cyclone preheater and the roasting furnace, and the first connecting inclined plate and the second connecting inclined plate are used for forcing the airflow to flow down along the volute-shaped cylinder walls of the cyclone preheater and the roasting furnace, so that the separation efficiency of material flow also can be improved even if a central tube is not arranged in the cyclone preheater.
Description
Technical field
The present invention relates to a kind of syndeton, relate in particular to a kind of in aluminum oxide production process, for cyclone preheater and the roasting furnace connecting structure of Aluminium hydroxide roasting.
Background technology
In alumina producing, there is the stoving oven of several types, for the roasting of aluminium hydroxide.Last procedure of producing aluminum oxide is that at the roasting kiln roasting than comparatively high temps, object is attached water and the crystal water removing in aluminium hydroxide the aluminium hydroxide that contains certain moisture after filter square position.In each alumina producer, applying at present maximum is exactly gas suspension calcination stove.Gas suspension calcination stove mainly contains the equipment compositions such as three grades of cyclone preheaters (PO1～PO3), stoving oven (PO4) and Category Four cyclone water cooler (CO1～CO4).In order to improve the separation efficiency of material, in first, second grade of cyclone preheater and Category Four cyclone water cooler, be provided with pipe core, but third stage cyclone preheater is directly connected with stoving oven, and temperature reaches more than 1000 DEG C in stove, common steel are difficult to be suitable under this operating mode, therefore it is very large to set up pipe core difficulty in third stage cyclone preheater, will greatly reduce like this separation efficiency of third stage cyclone preheater, the production capacity of whole stoving oven also can be affected.
Summary of the invention
In order to address the above problem, the invention provides a kind of cyclone preheater and roasting furnace connecting structure, object is to improve the separation efficiency of streams.
To achieve these goals, the present invention is achieved through the following technical solutions:
Cyclone preheater and roasting furnace connecting structure, comprise cyclone preheater and stoving oven, the top board of cyclone preheater is connected swash plate welding with first, the top board of stoving oven is connected swash plate welding with second, and first connects swash plate is connected swash plate connection also at grade with second.
A second described side that connects swash plate is provided with side plate, and side plate and vertical direction are 15 °～60 ° welding.
Described the first connection swash plate and horizontal plane angle are 15 °～60 °, and the second connection swash plate and horizontal plane angle are 15 °～60 °.
Advantage of the present invention and effect are as follows: the effect of side plate is to force air-flow to flow along the scroll casing shape barrel of cyclone preheater and stoving oven, first connects swash plate is connected swash plate with second, force air-flow to flow along cyclone preheater tube wall downwards, even if there is no pipe core in cyclone preheater like this, so also can improve the separation efficiency of streams.
Brief description of the drawings
Fig. 1 is plan structure schematic diagram of the present invention.
Fig. 2 is that stoving oven is connected the stereographic map that swash plate connects with side plate and second.
In figure: 1, the top board of cyclone preheater; 2, the top board of stoving oven; 3, first connects swash plate; 4, second connects swash plate; 5, side plate.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, cyclone preheater of the present invention and roasting furnace connecting structure, comprise cyclone preheater and stoving oven, the top board 1 of cyclone preheater is connected swash plate 3 with first and welds, the top board 2 of stoving oven is connected swash plate 4 with second and welds, first connects swash plate 3 is connected with second that swash plate 4 connects and at grade, a side of the second connection swash plate 4 is provided with side plate 5, and side plate 5 and vertical direction are β=15 °～60 ° of welding.The first connection swash plate 3 is 15 °～60 ° with horizontal plane angle α, and the second connection swash plate 4 is 15 °～60 ° with horizontal plane angle α.
Claims (1)
1. cyclone preheater and roasting furnace connecting structure, it is characterized in that being provided with side plate between cyclone preheater and stoving oven, the top board of cyclone preheater is connected swash plate welding with first, the top board of stoving oven is connected swash plate welding with second, first connects swash plate is connected swash plate connection also at grade with second, side plate and vertical direction are 15 °～60 ° welding, and the first connection swash plate and horizontal plane angle are 15 °～60 °, and the second connection swash plate and horizontal plane angle are 15 °～60 °.
