The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for the utility model is described, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, the two air channels of a kind of grain processing of the present utility model air classifier, it comprise air classifier housing 1, charging aperture 2, spiral harmonious material device 3, on drop down plate 4, under drop down plate 5, outer suction channel 6, interior suction channel 7, separator 8, inner blower 9, dust-settling compartment 10, screw input feeder 11, light assorted outlet 12, impurity removal pressure door 13, grain-export 14, put out cereal pressure door 15 and air-return duct 16, separator and inner blower are located in same cylindrical shell 17, and adopting dividing plate 18 to separate, the barrel of cylindrical shell is the involute surface shape.
The separator of this fanning machine for grain and the shell of inner blower share the cylindrical shell of an involute surface shape, have increased the stroke that light impurity separates, and have increased the time of light impurity and feed separation, have greatly improved the selection by winnowing effect of light impurity, and the material after selection by winnowing is purer.
Best, the progressive amount of the barrel of the cylindrical shell of this involute surface shape increases progressively with the inside suction channel in the center of separator, due to main still with the Membrane Separator Cylinder for CFB Boiler barrel near interior suction channel one side for light impurity and feed separation curved surface, thus, can increase the effective travel of light impurity and feed separation, and then improve the selection by winnowing effect.
Outer suction channel and interior suction channel are the vertical air suction road, the vertical air suction road must be the rectangular cylindrical shell that possesses wall, certain width, thickness and height are arranged, air-flow enters air channel by light impurity and the good material web of small part while in the bottom in air channel, passing material, enter the material of not running well or the impurity in air channel, because the aspects such as its granularity, floating velocity there are differences, in air channel, all under the effect of gravity and the contrary power of this both direction of suspending power, be selected, be selection by winnowing, light impurity is siphoned away by wind, and good material comes back in the main flow of material.
The bottom of cylindrical shell 17 is provided with Multi-aperture adjustable throttle 19.Preferably, this Multi-aperture adjustable throttle 19 comprises the quiet plate of air door and the moving plate of air door, and the quiet plate of air door and cylindrical shell 17 are fixing, and the moving plate of air door can slide with respect to the quiet plate of air door, and the quiet plate of air door is provided with a plurality of wind hole.In addition, the position that can be positioned in the outside of air classifier housing 1 Multi-aperture adjustable throttle 19 is provided with access door 21, for overhaul of the equipments, also can facilitate air door to regulate.
Acting as of above-mentioned Multi-aperture adjustable throttle: on the one hand, moving plate by damper slides with respect to the quiet plate of air door, when the moving plate of air door slides to the quiet plate of air door, can increase the shutoff area in the wind hole on the quiet plate of air door, reduce air quantity, when the moving backboard of air door slides to the quiet plate of air door, can reduce the shutoff area in the wind hole of the quiet plate of air door, improve air quantity; On the other hand, this Multi-aperture adjustable throttle has also substituted existing wind deflector, can play the effect identical with wind deflector, and the air of purification is siphoned away by inner blower in the porous type air door enters the cylindrical shell of separator, then recycles via air-return duct.
Spiral harmonious material device 3 and on drop down between plate 4 and be provided with adjustable bin gate 20.The gap of this is adjustable bin gate 20 is adjustable.Preferably, adjustable bin gate 20 comprises the quiet plate 201 of bin gate and the moving plate 202 of bin gate, and the quiet plate 201 of bin gate is fixing with air classifier housing 1, and the moving plate 202 of bin gate can slide to regulate the gap between the moving plate 202 of bin gate and the quiet plate 201 of bin gate with respect to the quiet plate 201 of bin gate.When the moving plate of bin gate slides to the quiet plate of bin gate, the gap between the moving plate of the quiet plate of bin gate and bin gate diminishes gradually or closes, and can reduce the amount of feeding of material or stop charging; When the moving backboard of bin gate slides to the quiet plate of bin gate, the gap between the moving plate of the quiet plate of bin gate and bin gate becomes greatly gradually, can increase the amount of feeding of material.Best, the moving plate of the quiet plate of bin gate and bin gate is to the arc of spiral harmonious material device bending, and the moving plate of the quiet plate of the bin gate of arc and bin gate forms.The regulative mode of the moving plate of bin gate has multiple, can adopt the regulative mode of weight and hinge, and chain connection weight and bin gate move plate, regulate the glide direction of the moving plate of bin gate by the lifting of weight.
The two air channels of a kind of grain processing that technique scheme provides air classifier, its operation principle is: material enters air classifier inside through charging aperture 2, material is after the spiral harmonious material device 3 of charging aperture 2 belows, can be along being uniformly distributed on the whole width of machine, the below of spiral harmonious material device 3 is furnished with the adjustable adjustable bin gate 20 in gap, material by adjustable bin gate 20 out by the lower end of above dropping down plate 4 and enter outer suction channel 6, the top of outer suction channel 6 is provided with outer blower fan interface 61, give a dinner for a visitor from afar outside under the air draught effect of machine, the lighter impurity of part is siphoned away, purer material drops down the lower end that plate 5 enters into interior suction channel 7 under warp again, interior suction channel 7 connects inner blower 9, under the circulation wind action, further impurity heavier in material is drawn in separator 8, because the shell of separator 8 is the involute-type curved surface that is conducive to the separation of light impurity, and the air quantity that enters separator is regulated by Multi-aperture adjustable throttle 19, the light miscellaneous material that so more is conducive to separate falls into the dust-settling compartment 10 of separator below, finally, heavier light foreign material are discharged through the assorted on the lenient side outlet 13 of impurity removal pressure door 12 by spiral conveyer 11.Entered into the grain-export 14 of air classifier housing lower end by the Cereals of secondary selection by winnowing after-purification, the material hammer action pressure door 15 of putting out cereal is opened, and Cereals is discharged.The air be cleaned enters via Multi-aperture adjustable throttle 19 in the cylindrical shell of separator 8 and is siphoned away by inner blower 9, then recycles via air-return duct 16.
The light assorted outlet of the utility model fanning machine for grain is placed in the outside of air classifier housing, and has designed two vertical air suction roads, and material is taked to the secondary selection by winnowing, has improved selection by winnowing efficiency; Simultaneously, the shell of separator and inner blower shares the curved cylindrical shell of an involute-type, has increased the stroke that light impurity separates, and has greatly improved the selection by winnowing effect of light impurity, and the material after selection by winnowing is purer.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
