Abstract
The utility model relates to the storage device of a vortex preheater in a rotary kiln. An impeller 3 is arranged in the circular chamber 10 of a casing 2; a flange plate 5 and a balk cargo frame 7 are arranged on the lower part of the impeller 3; the joint of a feeding pipe 8 and the exhaust cylinder 9 of a next stage vortex preheater is provided with a balk cargo disc 11 whose surface is provided with a figure-eight strip-shaped bulge 12. The utility model has the advantages continuous and uniform baiting, high thermal efficiency, favorable air lock performance, etc., and the utility model can raise the output of the rotary kiln and reduce the pollution to the environment.
Description
The utility model relates to a kind of doffer that is used for the rotary kiln cyclone preheater.
The discharge of known rotary kiln cyclone preheater and lock wind are realized by veneer or two flap valve.Owing to flap valve is to move by the deadweight of material, thus material is evenly fallen continuously, thus reduced the heat exchanger effectiveness of hot blast and material, also influenced the output of rotary kiln simultaneously.Also,, increased the dust concentration in the emission gases, made environment be subjected to severe contamination so directly influence wind, the material separating effect of whirlwind tube because there is air leakage phenomena in flap valve.
Task of the present utility model is exactly the deficiency that exists according in the above-mentioned background technology, and design a kind of blanking continuously evenly, heat exchanger effectiveness is high, do not have air leakage phenomena, reduce the doffer of the rotary kiln cyclone preheater of dust pollution.
The technical solution of finishing above-mentioned task is: ring flange is positioned at below the impeller, have a surface under the ring flange and be provided with the bulk cargo frame of oblique strip projected parts, the junction of aiutage and tremie pipe is provided with the bulk cargo dish that a surface is furnished with strip projected parts, and impeller is installed on upper and lower in the funnelform housing.The cross section of said bulk cargo frame is a triangle, and the feed opening of ring flange is a Long Circle.Strip projected parts on the bulk cargo card is splayed and distributes.For having a circular cavity in the middle of the funnelform housing, impeller is positioned at circular cavity and rotates up and down.
Fig. 1: overall structure schematic diagram of the present utility model.
The A-A view of Fig. 2: Fig. 1.
Fig. 3: the B-B view of ring flange.
Fig. 4: the schematic diagram that combines of tremie pipe and aiutage.
Fig. 5: the D of bulk cargo dish is to view.
As shown in Figure 1 and Figure 2, below the whirlwind tube 1 of preheating in rotary kiln device, connect one upper and lower be the middle housing that is provided with circular cavity 10 of positive and negative funnel-form, the impeller 3 that is made of blade and axis is arranged in the circular cavity 10 of housing 2.Be provided with bulk cargo frame 7 below impeller 3, the cross section of this bulk cargo frame 7 is triangular in shape, also is provided with splay strip projected parts 6 on two inclined-plane.This bulk cargo frame 7 is bearing in (see figure 4) on the tube wall of tremie pipe 8.The bottom of housing 2 connects the ring flange 5(that is provided with Long Circle feed opening 4 in the middle of and sees Fig. 3).Tremie pipe 8 joins with the aiutage 9 of next stage cyclone preheater, and the bulk cargo dish 11 that also has a semicircle in the junction of the two, the upper surface of this bulk cargo dish 11 also are provided with splay strip projected parts 12(and see Fig. 5).
This device is in operation process, and the material that whirlwind tube 1 falls is stirred through housing 2 and by impeller 3, concentrates when material drops down onto ring flange 5 to fall into tremie pipe 8 by feed opening 5.Because the surperficial bulk cargo frame 7 that has splayed strip projected parts 6 has been installed in tremie pipe 8, and the material that falls is subjected to the shunting action of stopping of bulk cargo frame 7 and strip projected parts 6, material is evenly fallen continuously.Again because of the surperficial bulk cargo dish 11 that has splayed strip projected parts 12 being installed in the tremie pipe 8 and the junction of the aiutage 9 of next stage cyclone preheater, material also can fall into aiutage 9 continuously equably by strip projected parts 12 guiding shunting actions, thereby can improve the heat exchanger effectiveness of hot blast and material, improve the output of rotary kiln.Also because of the structural design of this device, outside air can not enter, and takes dirt gas channelling does not take place, and lock wind performance is good, has strengthened the separating effect of cyclone preheater, has reduced the dust content of emission gases, has reduced the pollution to environment.
The utility model has overcome the deficiency that exists in the background technology, relatively simple for structure, evenly blanking continuously, improved heat exchanger effectiveness, increased the output of rotary kiln, lock wind performance is good, and can improve the separating effect of cyclone preheater, reduce the dust content of emission gases, reduced pollution level.
