The specific embodiment
Be described further below in conjunction with accompanying drawing:
As shown in Figure 1, tealeaves look of the present invention selects winnowing machine to comprise that look selects structure, the tender tealeaves stream that is mixed with impurity enters from elevating hopper 1, dropping to the first material wheel 2, the first material wheels 2 has two effects, and one is to have equally spaced separated material tooth on the first material wheel, tealeaves enters after equally spaced separated material tooth, be sent to uniformly on conveyer belt, can be good at like this controlling the beat of sorting, for follow-up automatic packaging or further sorting a reasonable tealeaves stream flow is provided, two be the first material wheel 2 can be by tender tealeaves the top of tangentially throwing to the first conveyer belt 3 along wheel outer surface, tender tealeaves is due to the gravity fall of self, and be mixed in the frivolous sheet impurity therebetween buoyancy due to air, falling speed is more slow, what waft is also farther, like this in the time that frivolous sheet impurity drops to the first conveyer belt 3, cover tender tealeaves stream above, thereby frivolous sheet impurity (as the scraps of paper) becomes mutually independently state with tealeaves from tangling mutually state, on the other hand frivolous sheet impurity covers more easily being gathered image and identify by camera 4 of tender tealeaves stream above, afterwards the result after identification is issued to look and is selected the controller of structure, controller control the first air nozzle 7 impurities removals.Have a stabilier at the end of the first conveyer belt 3, this stabilier one is to eliminate the harmful effect of unstable air-flow to tender tealeaves stream, the 2nd, and can provide a tender tealeaves to enter the expected motion vector of denuded zone.In denuded zone, there is the first air nozzle 7, the first air nozzle 7 is jet obliquely upward, and this air-flow is on tender tealeaves stream substantially without affecting or under-effected to cause sorting unsuccessfully, but it can blow to impurities removal flitch 5 by frivolous sheet impurity, further, frivolous sheet impurity is discharged by the first impurity discharging port 6.
Select the tender tealeaves of selecting structure to flow to into selection by winnowing structure for the first time from look, tender tealeaves stream glided along benchmark swash plate 8 before this, benchmark swash plate 8 has fumarole at corresponding the second air nozzle 9 places, the second air nozzle 9 is along the normal direction ejection air-flow of benchmark swash plate, part heavy seeds glides and continues to glide along benchmark swash plate, and most tender tealeaves stream sprays to the upper surface of first point of materials and parts 10 under the effect of air-flow, and slide and go to the prolongation inclined-plane 12 of first point of materials and parts 10 below, extend inclined-plane 12 and the 3rd air nozzle 11 corresponding sections and also there is fumarole, tender tealeaves flows at this place again by selection by winnowing, the heavy seeds of some continues to glide along extending inclined-plane again, and most qualified tender tealeaves drops on the second conveyer belt 15 in the effect of second point of materials and parts 13.Due in modern tea dry sorting field, the flexible sorting capability of tea dry sorting streamline is very important, although the tea sorting machine sorting capability of Special Category is more excellent, but cannot adapt to the tea dry sorting of multiple types, and the quick switching actual needs of producing also to tea dry sorting flexible assembly line, requirements at the higher level is proposed.In this example, the distance between first point of materials and parts 10 and second point of materials and parts 13 and benchmark swash plate 8 threes is adjustable, can tackle like this impurity and the different types of tealeaves stream that are mixed with various different gravity characteristics.In general, the wind-force of the second air nozzle 9 is larger, and its effect is thick selection by winnowing, and large stone tree wind etc. is selected, and the 3rd air nozzle 11 wind-force are smaller comparatively speaking, can sub-elect the impurity such as branch, and two kinds of heavy seeds are discharged from the second impurity discharging port 14.Air-flow is from out entering afterwards 21 dedustings of dedusting cyclone selection by winnowing structure for the first time, so, select the stage there is no the lightweight thing of complete Ex-all at look, still can continue to remove in this stage.
The tender tealeaves stream that selection by winnowing goes out is for the first time delivered to selection by winnowing structure for the second time by the second conveyer belt 15, selection by winnowing structure and have sealing device between selection by winnowing structure for the second time for the first time, and such twice selection by winnowing is independent of each other.Selection by winnowing structure comprises air outlet 17 for the second time, and air outlet 17 blows out wind upwards, and the tender tealeaves that the second conveyer belt 15 ends are discharged flows under this wind action upwards, and the underproof heavy tealeaves of humidity directly falls into the first smart tea and collects mouth 16, treats following process; Qualified tender tealeaves flows under this wind action upwards, is blown to volute air return structure.Volute air return structure has the outer tube structure of air-supply and the inner tube structure of return air, its cross section is semicircle, windward is turning to 180 degree with tender tealeaves stream along the outer tube of volute air return structure, tender tealeaves stream is beaten to the second material wheel 19, the second material wheel 19 also has two functions, and one is also to have equally spaced separated material tooth on the second material wheel, and tender tealeaves enters after equally spaced separated material tooth, collect mouthful 18 discharges from the second smart tea uniformly, be convenient to follow-up processing; Second is that the second material wheel 19 has lock wind function, air-flow can be locked in volute air return structure and prevent that air-flow from leaking.When air-flow flows to inner tube from the outer tube of volute air return structure, 180 degree turn to again, due to turning to completely of air-flow, utilize fully blast, tender tealeaves is arranged in uniformly densely in the separated material tooth of the second material wheel equal intervals, tealeaves in separated material tooth is quantitative substantially like this, for the realization of finishing labor and materials packing below provides possibility.And the outer tube of volute air return structure and inner tube are all semi-circular section structures, no matter be air feed or return air, all make blast decline and reach minimum, reduce as far as possible the consumption of wind energy, those skilled in the art will be understood that, can adjust the section radius for airduct and backwind tube, thereby better adapt to air feed needs.Air-flow out enters afterwards 21 dedustings of dedusting cyclone from cochlear structures.Following table is the experimental data table of volute air return structure, if the cross section of volute air return structure adopts rectangle, strengthened greatly windage, this has strengthened burden to air supply system, has also strengthened energy consumption, if adopt semicircular cross section, windward can be excessive very stably, also not clearly and shock volute backwind tube inwall of tealeaves, therefore, it is little that tealeaves damages, and air loss is also very little.Preferably, the diameter of outer tube equals the diameter of inner tube.
More preferably, the quantity of the separated material tooth of the first material wheel is less than the separated material number of teeth of the second material wheel, because in the time that mixing tealeaves stream does not enter sorting, may comprise some larger foreign matter or foreign material, as separated material tooth arrange overstocked, possible these large foreign material cannot enter between separated material tooth, more dangerous is by stuck whole feeding system, but at the second material wheel place, tealeaves stream has been removed all kinds of foreign material, herein, can for follow-up processing or packing provide one stable, quantitative tealeaves stream seems even more important, therefore, separated material space width diminishes, separated material tooth increases.Because the first material wheel need to flow upthrow by tealeaves, a tripping force will be provided, therefore select thicker separated material tooth transverse tooth thickness, and there are not such needs in the second material wheel, its separated material tooth transverse tooth thickness is relatively little.A preferred scheme is, the separated material tooth crown angle of the first material wheel is 8-10 degree, and the separated material tooth crown angle of the second material wheel is 4-6 degree, like this both correspondences different transverse tooth thickness.
More preferably, the first material wheel, the rotating speed of the second material wheel is by controller control, a charging flow speed value corresponding to speed of the first material wheel, when controller obtains the first impurity discharging port, the second impurity discharging port, the first smart tea is collected after the flow velocity of discharge of mouth, can calculate the theoretical discharge flow speed value of the second material wheel, then this value is assigned to drive motors, thereby obtain an instant rational second material wheel speed.It will be understood by those skilled in the art that also can be take the flow velocity of the second material wheel discharge as benchmark, carrys out the speed of the first material wheel charging of the theory of computation, thereby better adapts to processing or the packing after sorting process.
The first smart tea is collected mouth 16 and is connected with material return system 22, and what the first smart tea was collected mouthful 16 collections is the excessive tender tealeaves of humidity, and this tea is expect recovery and further process, and material return system comprises oven dry portion, the portion of weighing, inlet section and conveyance conduit.When the excessive tender tealeaves of humidity collects mouthfuls 16 while entering into material return system 22 from the first smart tea, first through an oven dry, the routine that the mode of drying is those skilled in the art is selected, due to selecting in tea process in reality, the excessive tender tealeaves of humidity accounts for entirety, and to mix the proportion of tealeaves stream little, the power consumption that therefore if material return system always can be very in opening, so preferred, add at material return system the portion of weighing, only have when after the tealeaves of the constant weight that material return system is collected, oven dry portion just moves, reach after certain hour, be transferred pipeline by wind-force and return to the first aidr bells blast system.Why returning to the first aidr bells blast system is because in drying course, may produce qualified chip or the defective work of similar yellow leaf, if these tealeaves directly enter selection by winnowing for the second time, directly enters final certified products, affects overall product quality.Entering after the second selection by winnowing, the defective work of chip or similar yellow leaf is sent to dedusting cyclone 21 and is removed.
The exhaust outlet of dedusting cyclone 21 is connected with pressure fan 20, pressure fan 20 is connected with the first to the 3rd air nozzle, air outlet 17, and for these structure air-supplies, on each air-supply branch road and return air branch road, have flow control valve, from following the sorting on border factually need to select air force.Look selects structure, selection by winnowing structure and have sealing device between selection by winnowing structure for the second time for the first time, except the tender tealeaves stream of necessity passes through, the air-flow that prevents each stage interferes with each other, and can select structure and selection by winnowing structure and for the first time selection by winnowing structure and also establish for the second time material wheel between selection by winnowing structure for the first time at look, because material wheel itself has the function of lock wind, but also can control flow.
Finally, tender tealeaves, after look choosing, the first two selection by winnowing, has successively been removed flake light thing, dust; The weight such as stone, bark, is also divided into smart tealeaves two kinds of different brackets, has all used material wheel before and after sorting streamline, and two material wheels making whole streamline even for discharge, and whole piece streamline to take up an area space little, joint structure is simple, has saved manufacturing cost.
Although select winnowing machine to carry out special description with reference to embodiment to the disclosed a kind of look relating to; embodiment described above is illustrative and not restrictive; without departing from the present invention, all variations and modification are all within protection scope of the present invention.
