Description

Air classifier and reducing mechanism with external air channel structure
Technical field
It the utility model is related to micronizer air classifier, more particularly to a kind of air classifier with external air channel structure And reducing mechanism.
Background technology
Micronizer is realized using the form of the impact of tup and gear ring, collision, friction, shearing, Gas grinding The equipment of crushing material, air classifier are the significant components of micronizer, and at work, the scroll feeder above air classifier will Material is sent into air classifier, and material to be comminuted is passed through air classifier and sucks shredder assemblies by the blower fan in micronizer system carries out powder It is broken;Air classifier is to be classified what is cleaned using the composition proportion difference in material.Its effect is by big miscellaneous (iron and the stone in material Block and heavy impurity) discharge of directly falling, counter-current fractionation, the small cereal of proportion enter wind under the suction of wind from bottom to top Pulverizing chamber;In actual production, because material different specific weight often changes, discharge it is big it is miscellaneous in be often accompanied by many suitable materials, thing Material screen selects less efficient.
In production, in order to improve selection by winnowing efficiency, the regulation door of regulation screening air-flow is typically provided in air classifier, And the regulation door is directly spread out of due to facing ultramicro grinding machine inlet, micronizer noise, micronizer is added Operating noise, had a strong impact on the health and working environment of operating personnel.
Utility model content
The purpose of this utility model is to provide a kind of air classifier and reducing mechanism with external air channel structure, and it has It is easy for installation, the advantages of selection by winnowing efficiency high and low noise are stable.
The utility model is achieved like this, a kind of air classifier with external air channel structure, it include housing and Respectively positioned at case top, sidepiece and the charging aperture of bottom, material discharging opening and impurity discharging port, it is characterised in that charging aperture, material Discharging opening and impurity discharging port connect with the material wind selection passage in housing;The hull outside is provided with and material wind selection channel parallel Accessory channel.
Preferably:The accessory channel is positioned close on material discharging opening and housing exterior walls corresponding thereto.
The downside of the accessory channel is air inlet, the horizontal duct dividing plate that the gas channel in the accessory channel is built It is divided into parallel and connection upper wind path and lower wind path.
The accessory channel is provided with damper close to air inlet.
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 external 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, air channel is aided in by the external selection by winnowing for increasing improved structure on air classifier, to it is big it is miscellaneous in qualified thing While material is screened, reduce air-flow wind and make an uproar, also improve the efficiency of material screening, simple to operate, reliable operation;Together When, by rationally setting the position of damper, the size of screening air-flow can be adjusted exactly, low wind noise is further dropped, also carries The high efficiency of pulverizer 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 inlet 8, damper 9, air-duct clapboard.
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 the air classifier bag with external air channel structure Include housing 1 and respectively positioned at charging aperture 2, material discharging opening 3 and the impurity discharging port 4 of the top of housing 1, sidepiece and bottom, its structure Feature 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 outside of housing 1 Provided with the accessory channel 6 parallel with material wind selection passage 5;In the specific implementation, the accessory channel 6 is positioned close to material and gone out In material mouth 3 and the outer wall of housing 1 corresponding thereto;The downside of the accessory channel 6 is air inlet 7, the air-flow in the accessory channel 6 The horizontal duct dividing plate 9 that passage is built is divided into parallel and connection upper wind path and lower wind path.At work, containing impurity Material enters from charging aperture 2, and mixed material is fallen under gravity, while screens air-flow and sail against the current from bottom to top, mixing Heavy materials such as big miscellaneous (iron, stones) in material falls directed along material wind selection passage 5, finally from the row of impurity discharging port 4 Go out, and the small cereal of proportion is discharged in the presence of air-flow is screened by material discharging opening 3;Because material different specific weight often has change Change, it is big it is miscellaneous in be often accompanied by many suitable materials, and by the air-flow of air inlet 7 then by entering upper wind path, upper wind path after lower wind path The qualified material of big hybrid will be blown into material discharging opening 3 by face material discharging opening 3, the high velocity air in it, so Can be reduced using accessory channel 6 be mixed into it is big it is miscellaneous in qualified material discharge rate, effectively improve the cleaning efficiency of material, while gas Wind path and lower wind path are flowed through, in the inside turn 180 degree of accessory channel 6, noise is spread out of downwards through air channel, can effectively reduce work Noise.
In order to improve the convenience of the reliability of air classifier work and operation, the accessory channel 6 is set at air inlet 7 There is damper 8;The damper 8 is board plug type structure, and is fixed by threaded fastener, can so pass through damper 8 flexible is conveniently adjusted intake, and reliable accurate, while cleaning efficiency is improved, the wind for reducing its work is made an uproar.
The invention also discloses a kind of reducing mechanism, and it includes shredder assemblies, it is characterised in that it also includes right It is required that the air classifier with external air channel structure in 1-5 described in any one, material discharging opening 3 and the crushing group of the air classifier Part is connected, and the qualified material after air classifier screens is entered in shredder assemblies through material discharging opening 3, by comminuting matter The later material of iron, stone and caking clears, and while protecting the workpiece such as tup, gear ring in shredder assemblies, also improves The efficiency of material wind selection, reduce the noise of work.
