With stable, the advantages of selection by winnowing efficiency high and reliable low noise.
The utility model is achieved like this, a kind of air classifier with interior air channel structure, it includes housing and divided
Wei Yu case top, sidepiece and the charging aperture of bottom, material discharging opening and impurity discharging port, it is characterised in that charging aperture, material go out
Material mouth and impurity discharging port connect with the material wind selection passage in housing；The inner walls are provided with auxiliary with material wind selection channel parallel
Help air channel.
The lower end of the impurity discharging port is provided with air-intake device.The middle part of the material wind selection passage is provided with damper.
The upper end in the auxiliary air channel is located at the top of impurity discharging port close to material discharging opening, lower end.
Preferably：The damper is board plug type structure.
The utility model also describes a kind of reducing mechanism, and it includes shredder assemblies, it is characterised in that it also includes above-mentioned
The air classifier with interior air channel structure of structure, the material discharging opening of the air classifier connect with shredder assemblies.
The beneficial effects of the utility model are：The utility model describes a kind of selection by winnowing efficiency high, easy for installation and low noise
Reliable air classifier, by the air classifier of improved structure, add built-in selection by winnowing auxiliary air channel, can to it is big it is miscellaneous in qualified thing
Material carries out Cycle Screening, substantially increases the efficiency of material screening, simple to operate, reliable operation；Meanwhile by rationally setting tune
The position of air door is saved, while air-flow is screened in regulation, the wind that can significantly reduce air classifier work is made an uproar, and also improves pulverizer work
The efficiency of work and the quality of product.
Brief description of the drawings
Fig. 1 is the structural front view of the utility model one embodiment.
Fig. 2 is the structural side view of embodiment illustrated in fig. 1.
In figure, 1, housing 2, charging aperture 3, material discharging opening 4, impurity discharging port 5, material wind selection passage 6, auxiliary wind
Road 7, air-intake device 8, damper.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the utility model is achieved in that there is the air classifier of interior air channel structure to include shell for this
Body 1 and charging aperture 2, material discharging opening 3 and the impurity discharging port 4 for being located at the top of housing 1, sidepiece and bottom respectively, its design feature
It is that charging aperture 2, material discharging opening 3 and impurity discharging port 4 connect with the material wind selection passage 5 in housing 1；The inwall of housing 1 is provided with
The auxiliary air channel 6 parallel with material wind selection passage 5；At work, the material containing impurity enters from charging aperture 2, mixed material
Fall under gravity, while screen air-flow and sail against the current from bottom to top, the proportion such as big miscellaneous (iron, stone) in mixed material
Big material falls directed along material wind selection passage 5, is finally discharged from impurity discharging port 4, and the small cereal of proportion is in screening air-flow
In the presence of discharged by material discharging opening 3；Because material different specific weight often changes, discharge it is big it is miscellaneous in be often accompanied by it is many suitable
Material, at this moment screening air-flow blows the suitable material at impurity discharging port 4, and re-enters into material wind selection through auxiliary air channel 6
The upper end of passage 5 so that more qualified materials can be blown into material discharging opening 3, reduce be mixed into it is big it is miscellaneous in qualified material
Discharge, the repeatable suction of such air classifier be mixed into it is big it is miscellaneous in qualified material, be so remarkably improved cleaning efficiency, increase is qualified
Material yield.
In order to reduce the noise of air classifier work, the reliability of its work and the convenience of operation, the impurity discharging port 4 are improved
Lower end be provided with air-intake device 7；The middle part of the material wind selection passage 5 is provided with damper 8；Because damper 8 is located at thing
Expect the middle part of selection by winnowing passage 5, it is set farther out with the charging aperture 2 above material wind selection passage 5 and material discharging opening 3, and enters
Material wind selection passage 5 between material mouth 2 and material discharging opening 3 and damper 8 is bend, and one side damper 8 is adjustable
The intake that air-intake device 7 enters impurity discharging port 4 and material wind selection passage 5 is saved, cleaning efficiency can be effectively improved, while reduce wind
Select the noise around device and pulverizer；In the specific implementation, the upper end in the auxiliary air channel 6 is close to material discharging opening 3, lower end
Positioned at the top of impurity discharging port 4, air-flow is so screened first through impurity discharging port 4 then again respectively through material wind selection passage 5 and auxiliary air channel 6
Adverse current upwards, by impurity discharging port 4 it is big it is miscellaneous in qualified material be re-delivered to the top of material wind selection passage 5, be blown into thing
Expect in discharging opening 3, when mounted, the damper 8 is board plug type structure, and is fixed by threaded fastener, can so be led to
Overregulate the flexible of air door 8 and be conveniently adjusted intake, it is reliable accurate, while cleaning efficiency is improved, reduce its work
Wind is made an uproar.
The invention also discloses a kind of reducing mechanism, and it includes shredder assemblies, and it is upper that it is structurally characterized in that it also includes
The air classifier with interior air channel structure of structure is stated, the material discharging opening 3 of the air classifier is connected with shredder assemblies, sieved through air classifier
Qualified material after choosing is entered in shredder assemblies through material discharging opening 3, in returning the iron in comminuting matter, stone and caking
