The below describes the course of work of integrated separation machine mentioned above.

1, primary separation process

Mixture to be separated (comprising larger pieces of material, bulky grain, granule and gas) enters the integrated separation machine from the air inlet of the inlet chamber 10 of integrated separation machine.Larger pieces of material in the mixture (such as polybag, band etc.) is subject to the retardance of the ring grate 19 of near the grid grate 18 of air inlet and 4 peripheries, centrifugal chamber, or hits or be suspended on the grate bar, falls into the discharge bin of housing 2 bottoms under Action of Gravity Field along the bar downslide.Bulky grain in the mixture also falls under gravity into discharge bin.Material in the discharge bin can be from the discharge port discharging, and is delivered to the precalculated position by the light material conveyer.

In this primary separation process, above-mentioned integrated separation machine advantage structurally comprises:

(1), because the roof in centrifugal chamber 4 is lower than the top certain altitude of needle rotor 3, so needle rotor 3 can decomposite a revolving force to centrifugal chamber 4 outside, aggravate the centrifugation of larger particles.

(2), because the top cover of housing 2 is stepped, therefore bulky grain just falls in the first top cover 21 lower zones, the mixture of granule and gas is then in the zone that further enters under the wind-force effect below the second top cover 22, and then enters in the centrifugal chamber 4 and separate.That is to say that mixture is in the climbing process, because the space becomes large and the abatement of wind, thereby being beneficial to bulky grain falls under Action of Gravity Field, thereby improves the separative efficiency of this primary separation process.

(3), the second sidewall of housing 2 respectively and the junction between the 3rd sidewall and the 4th sidewall and the junction between the 3rd sidewall and the first side wall all be provided with the arc transition plate, so that the junction forms arc transition, thereby suppress the formation of the turbulent flow in housing 2 inner chambers, improve separating effect.

(4), be provided with arc filter screen 20 on the windward side of ring grate 19 (i.e. the face of close inlet chamber 10), therefore when needle rotor 3 does not rotate, the local arc filter screen 20 of hanging up can stop light material (such as polybag, band etc.) to enter in the centrifugal chamber 3 on the ring grate 19, is convenient to the maintenance of needle rotor 3.

(5), the sidewall of housing 2 is provided with access panel, thereby maintains easily the parts of housing 2 inside.

2, the second-order separation process

The gas of separating in primary separation process and short grained mixture enter centrifugal chamber 4, under needle rotor 3 High Rotation Speeds drive, and High Rotation Speed thereupon, thus mixture is separated into granule and gas under centrifugal action.On the one hand, granule in the mixture (dust granule) is applied in larger centrifugal force, so that granule carries out outwards downward centrifugal motion, cause dust granule to arrive on the sidewall in centrifugal chamber 4, so dust granule moves downward along centrifugal chamber 4 sidewalls, fall in the material-falling hopper 9, thereby be disposed in the second collection ash can 15.On the other hand, the centrifugal force that the gas of relative clean is subject to is less, therefore enters the cavity center in centrifugal chamber 4, forms downward strong eddy flow.When arriving 4 bottom, centrifugal chamber, enter exit cone 5 inside, continue to do high speed circumnutation (effect at exit cone 5 and stem stem 6 is to reduce turbulent flow so that gas forms more regular eddy flow) around stem stem 6, discharge by outlet chamber 11 and outlet pipe at last.

It more than is the second-order separation process of dry dust removal mode.If as indicated above, the integrated separation machine also is provided with liquid-jet device, then can adopt preferred semi-wet dedusting method to carry out above-mentioned the second-order separation process.That is to say, after gas and short grained mixture enter centrifugal chamber 4, atomizer 17 ejection atomizing liquid grains (for example water), thus granule can be assembled liquid grain surface, so that particle increases, therefore can reduce it by the possibility of turbulent perturbation.

In this second-order separation process, above-mentioned integrated separation machine advantage structurally comprises:

(1), the bottom section by the sidewall in centrifugal chamber 4 is formed with the interrupted cylindrical void 41 that distributes of annular, therefore isolated granule can arrive the outside (being the space between centrifugal chamber and the housing 2) in centrifugal chamber 4 in time by these long and narrow cylindrical voids 41, further realize with the separating of gas in, originally the granule of High Rotation Speed can reduce its rotary speed significantly through after the cylindrical void 41, thereby the granule that arrives 4 outsides, centrifugal chamber can easily be deposited in the material-falling hopper 9 under Action of Gravity Field, thereby reaches preferably separating effect.

(2), because the top (being the upper peripheral edge of cylindrical portion 91) of the diapire in centrifugal chamber 4 and material-falling hopper 9 certain distance apart on the central axial direction in centrifugal chamber 4, therefore between the top of the diapire in centrifugal chamber 4 and material-falling hopper 9, constructed a longitudinal buffer district (namely the central axial direction in centrifugal chamber 4 has formed the slit buffer circle), further reduced the granule rotary speed, thereby under Action of Gravity Field, be deposited in the material-falling hopper 9 more easily, reach preferably separating effect.

(3), the open top of material-falling hopper 9 (being the open top of cylindrical portion 91) is greater than the bottom opening in centrifugal chamber 4 (being the second opening of the diapire in centrifugal chamber 4 mentioned above).Therefore, on the one hand, between the bottom opening in the open top of material-falling hopper 9 and centrifugal chamber 4, constructed a horizontal buffering area (namely having formed buffering area along the direction vertical with the central axis in centrifugal chamber 4), further reduced the granule rotary speed, thereby under Action of Gravity Field, be deposited in the material-falling hopper 9 more easily, reach preferably separating effect; On the other hand, because material-falling hopper 9 open tops are larger, therefore the granule from centrifugal chamber 4 can be received in the material-falling hopper 9 fully.

(4), be coated with annular oriffice 8 on the material-falling hopper flange 7.Annular oriffice 8 is fully ensureing under the condition that granule sees through, can reduce air-flow in the centrifugal chamber 4 to the probability of material-falling hopper 9 inner penetrations by forming resistance, thereby reduce air-flow to the disturbance of granule sedimentation, so that granule can be deposited in the material-falling hopper 9 more easily, reach preferably separating effect under Action of Gravity Field.

(5), be provided with some blades 94 on the outer peripheral face of annular canister section 93, the shape of blade 94 is roughly the tabular of inclination, and incline direction is consistent with centrifugal chamber 4 interior flow rotation directions.Preferably, a plurality of blades 94 connect by annular slab 95.Therefore, even some flows to material-falling hopper 9 from the air-flow in the centrifugal chamber 4 by annular oriffice 8, the blade 94 that arranges on the outer peripheral face of the annular canister section 93 of this material-falling hopper 9 can steering current swirl velocity transform to axial velocity, reduce air-flow to short grained disturbance, the short grained rotation that intercepts in the material-falling hopper 9 is risen.By annular slab 95 a plurality of blade 94 is interconnected along circular path, thereby annular slab 95 can form resistance, the outer shroud air-flow that stops relatively high pressure passes through and forms turbulent flow to the interior zone of relatively low pressure, thereby further reduces air-flow to short grained disturbance, improves separating effect.

(6), since exit cone 5 be provided with a plurality of holes 51 side wall ring week, therefore the gas of separating is when arriving 4 bottom, centrifugal chamber, be positioned at the air-flow of exit cone 5 outsides except the upper peripheral edge from exit cone 5 enters exit cone 5, most of air-flow can also enter exit cone 5 by a plurality of holes 51 on exit cone 5 sidewalls.If air-flow enters exit cone 5 from the upper peripheral edge of exit cone 5, then because the upper peripheral edge border of exit cone 5 can generate turbulent flow, therefore can produce disturbance to granule on every side; And if air-flow enters exit cone 5 by a plurality of holes 51 on exit cone 5 sidewalls, then air-flow can pass more lenitively hole 51 and enter exit cone 5 in rotary course, reduce the generation of turbulent flow, thereby reduce short grained disturbance on every side, reach better separating effect.More preferably, hole 51 is arranged on the upper area of the sidewall of exit cone 5.The gas of separating is when arriving 4 bottom, centrifugal chamber; the air-flow that is arranged in exit cone 5 outsides progressively enters exit cone 5 in the process that rotates up around exit cone 5; rotate up in the process at this; the granule that is mingled with in the air-flow can obtain sedimentation under Action of Gravity Field; therefore more near the top of exit cone 5, the granule that is mingled with in the air-flow is fewer.Therefore, hole 51 only is arranged on the upper area of the sidewall of exit cone 5, can prevent from being positioned at being mingled with of initial stage fiaring cone 5 lower areas more short grained air-flow and enter exit cone 5, further improves separating effect, purifies the gas of discharging from outlet chamber 11.

(7), the roof 111 of outlet chamber 11 is lower than material-falling hopper flange 7 certain distances.Therefore form the convolution zone between the roof of outlet chamber 11 and material-falling hopper flange 7, the air-flow that flows out from exit cone 5 convolutions can continue to circle round this circles round the zone.Because this convolution zone is comparatively regular substantial cylindrical, therefore air-flow can form regular eddy flow in this convolution process, thereby when entering in the not too regular outlet chamber 11, can reduce the generation of turbulent flow follow-up, reduce the possibility of altering on the air-flow, and then improve separating effect.

(8), at least part of ring grate bar of ring in the grate 19 extends to the second annulus 72 of material-falling hopper flange 7 from the second top cover 22 of housing 2, and is fixed on this second annulus 72.This part ring grate bar can be used for the welding location of the material-falling hopper 9 of material-falling hopper flange 7 belows, controls welding deformation, and can guarantee the axiality of centrifugal chamber 4, material-falling hopper flange 7 and material-falling hopper 9.

The course of work of this wind sorting system is: treat that sorting material is separated into heavy thing and lightweight thing by winnowing machine first, the heavy thing is delivered to assigned address by heavy thing conveyer, and the lightweight thing is then sent in the integrated separation machine and further separated.In the integrated separation machine, the lightweight thing is through primary separation and the second-order separation, in primary separation process, wherein isolated larger pieces of material and bulky grain are delivered to the precalculated position by the light material conveyer, rest materials is separated into granule and gas by the second-order separation process, its small particles is disposed in the second collection ash can 15, the gas of relative clean is then discharged from the outlet chamber 11 of integrated separation machine, a part is circulated to the air intake vent of the blower fan 31 of winnowing machine, another part by the overflow of overflow blower fan to external environment condition.

This wind sorting system is except the structural advantage separately with above-mentioned winnowing machine and integrated separation machine, also has following structural advantage: owing to be provided with overflow blower fan 38, therefore can be so that keep little negative pressure in the system, reduce windage, and owing to overflow blower fan 38 is connected with the outlet chamber 11 of integrated separation machine, so overflow route is shorter, and without blower fan 31, thereby further reduce windage, reduce ineffective energy consumption.

(2), because the diapire 102 of inlet chamber 10 is lower than the roof certain distance in centrifugal chamber 4, therefore make the bulky grain of the High Rotation Speed of separating in infall process, reduce rotary speed, the bulky grain of separating is densification progressively if having time, can accumulate on the diapire 102 of inlet chamber 10, flow in the centrifugal chamber 4 but be unlikely to enter, thereby also can reduce bulky grain to the wearing and tearing in centrifugal chamber 4.

(3), the hole on the snail ring is arcuate socket 1021, arcuate socket 1021 is compared with existing circular hole and is had the following advantages.The aperture of circular hole can not be too large (comparing with the size of snail ring), so the delay area between the circular hole is larger, thereby also has more bulky grain can be trapped on the snail ring between the circular hole, is difficult to fall into the periphery of housing 2 inner chambers.The arc radius of arcuate socket 1021 then can be large (even can be suitable with the size of snail ring), so the delay area between the arcuate socket 1021 is then less, thereby only has a small amount of bulky grain to be trapped on the snail ring between the arcuate socket 1021.Because bulky grain major part under centrifugal action is gathered in the position near the outer peripheral edges of snail ring, and arcuate socket 1021 can be pressed close to the outer peripheral edges setting of snail ring, thereby further impels most of bulky grain to waltz through the periphery that arcuate socket 1021 falls into housing 2 inner chambers.

(4), owing to be provided with the guided plate 14 of inclination in the inner chamber of housing 2, the bulky grain that therefore falls in the inner chamber of housing 2 can slide to elementary blanking port along guided plate 14, thereby accelerates the velocity of discharge of bulky grain thing.

2, the second-order separation process

The gas that is positioned at the center of separating in primary separation process and short grained mixture enter centrifugal chamber 4, under needle rotor 3 High Rotation Speeds drive, and High Rotation Speed thereupon, thus mixture is separated into granule and gas under centrifugal action.On the one hand, granule in the mixture (dust granule) is applied in larger centrifugal force, so that granule carries out outwards downward centrifugal motion, cause dust granule to arrive on the sidewall in centrifugal chamber 4, so dust granule moves downward along centrifugal chamber 4 sidewalls, fall in the material-falling hopper 9, thereby be disposed in the second collection ash can 15.On the other hand, the centrifugal force that the gas of relative clean is subject to is less, therefore enters the cavity center in centrifugal chamber 4, forms downward strong eddy flow.When arriving 4 bottom, centrifugal chamber, enter exit cone 5 inside, continue to do high speed circumnutation (effect at exit cone 5 and stem stem 6 is to reduce turbulent flow so that gas forms more regular eddy flow) around stem stem 6, discharge by outlet chamber 11 and outlet pipe at last.

It more than is the second-order separation process of dry dust removal mode.If as indicated above, dust removal machine also is provided with liquid-jet device, then can adopt preferred semi-wet dedusting method to carry out above-mentioned the second-order separation process.That is to say, after gas and short grained mixture enter centrifugal chamber 4, atomizer 17 ejection atomizing liquid grains (for example water), thus granule can be assembled liquid grain surface, so that particle increases, therefore can reduce it by the possibility of turbulent perturbation.

In this second-order separation process, above-mentioned dust removal machine advantage structurally comprises:
