The North Sea sincere moral rotary kiln is the sincere moral Phase IV project in the North Sea, has four lines, is mainly used in, to the selected work of lateritic nickel ore, belonging to novel process.Raw ore enters into rotary kiln and carries out high melt process after broken, dry, batching, pressure ball process, and then enter enrichment plant and carry out selected, wherein the control of kiln temperature is particularly crucial to whole technique; In normal productive process, the temperatures as high of rotary kiln end 1400 degrees Celsius, although there is refractory material to protect, too high temperature still causes damage to kiln body, makes rotary kiln head part produce distortion.
In order to protect rotary kiln head part not burnt out by high temperature, the method that prior art is taked is: the axial flow blower installing 12 Φ 800 in the kiln hood part of every bar line, adopts axial flow blower to cool the blowing of kiln body.The method that prior art is taked needs the support at kiln hood fabrication and installation axial flow blower, and the kiln hood purchasing 48 every bar lines of axial flow blower installs 12, article four, line just needs 48, the support of fabrication and installation axial flow blower and purchase axial flow blower, not only labor intensive, financial resources, take up room large, and discovery axial flow blower cooling effect is not very desirable after the trial production of Article 1 line.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rotary kiln end cooling system, and not only cost is low, and can reach desirable cooling effect, ensures to produce to carry out smoothly.
The utility model solves the rotary kiln end cooling system that its technical problem adopts, and comprises air inducing blower fan, blower duct and connecting pipe; One end of described connecting pipe is connected with the fan outlet of described air inducing blower fan, and the other end is connected with blower duct, described blower duct is provided with at least one air outlet, and described air outlet is towards kiln hood cylindrical shell.
Further, the axis of described blower duct and the axis being parallel of kiln hood cylindrical shell, described air outlet is just to the axis of kiln hood cylindrical shell.
Further, the two ends of described blower duct are provided with sealing plate.
Further, the quantity of described air outlet is 4, is evenly arranged on blower duct.
Further, the spacing between adjacent two air outlets is 1m.
Further, described air outlet is of a size of 200*500mm.
Further, described blower duct is supported by support column.
Further, described support column is arranged on brace table.
The beneficial effects of the utility model are: through pilot production, adopt air inducing blower fan cooling raio axial flow blower cooling effect better, can produce a desired effect, ensure to produce and carry out smoothly.Directly utilize the air-out cooling kiln hood cylindrical shell of air inducing blower fan, not only save the expense of buying axial flow blower, and utilize original air inducing blower fan to save the electric power resource using axial flow blower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Shown in Fig. 1: 1-kiln head cover, 2-scrapper conveyor, 3-air inducing blower fan, 31-fan outlet, 4-blower duct, 41-air outlet, 42-sealing plate, 5-connecting pipe, 6-brace table, 7-support column, 8-kiln hood cylindrical shell.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Discharging due to rotary kiln head-shield 1 adopts scrapper conveyor 2 to transport, and in order to cool from rotary kiln high-temperature liquid state ore deposit out, scrapper conveyor 2 li adopts turbid circulating water cooling, can produce a large amount of steam therebetween; To cause damage in order to avoid steam is run helter-skelter to other equipment, in prior art, steam is taken away loose being discharged in air by design employing air inducing blower fan 3.
As Fig. 1 shows, rotary kiln end cooling system of the present utility model, comprises air inducing blower fan 3, blower duct 4 and connecting pipe 5; One end of described connecting pipe 5 is connected with the fan outlet 31 of described air inducing blower fan 3, and the other end is connected with blower duct 4, described blower duct 4 is provided with at least one air outlet 41, and described air outlet 41 is towards kiln hood cylindrical shell 8.The air-out of described air inducing blower fan 3 enters blower duct 4 by connecting pipe 5, then blows to kiln hood cylindrical shell 8 by air outlet 41, cools kiln hood cylindrical shell 8.Blower duct 4 and connecting pipe 5 all can adopt steel pipe, and such as, blower duct 4 and connecting pipe 5 all can adopt Φ 1020 steel pipe matched with the fan outlet 31 of air inducing blower fan 3.Through pilot production, adopt air inducing blower fan 3 cooling raio axial flow blower cooling effect better, can produce a desired effect, ensure to produce and carry out smoothly.Directly utilize the air-out cooling kiln hood cylindrical shell 8 of air inducing blower fan 3, not only save the expense of buying axial flow blower, and utilize original air inducing blower fan 3 to save the electric power resource using axial flow blower.
