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 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, and gliding along bar under Action of Gravity Field falls into the discharge bin of housing 2 bottoms.Bulky grain in mixture also falls under gravity into discharge bin.Material in 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), due to the roof in the centrifugal chamber 4 top certain altitude lower than 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 in the zone that further enters under the wind-force effect below the second top cover 22, and then enters in centrifugal chamber 4 and separate.That is to say, mixture in the climbing process, the abatement of wind because the space becomes large, thus being beneficial to bulky grain falls under Action of Gravity Field, thereby improve 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, make the junction form 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, on ring grate 19, the local arc filter screen 20 of hanging up can stop light material (such as polybag, band etc.) to enter in centrifugal chamber 3, 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 mixture (dust granule) is applied in larger centrifugal force, make granule carry 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 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 make gas to form more regular eddy flow, reduces turbulent flow) around stem stem 6, discharge by outlet chamber 11 and outlet pipe at last.

It is more than 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, 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, makes particle increase, and 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 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 cylindrical void 41, thereby the granule that arrives 4 outsides, centrifugal chamber can easily be deposited in material-falling hopper 9 under Action of Gravity Field, thereby reaches separating effect preferably.

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

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

(4), be coated with annular oriffice 8 on material-falling hopper flange 7.Annular oriffice 8 is fully ensureing under the condition that granule sees through, can reduce the interior air-flow in 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, make granule to be deposited in material-falling hopper 9 under Action of Gravity Field more easily, reach separating effect preferably.

(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 the interior flow rotation direction in centrifugal chamber 4.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 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 material-falling hopper 9 is risen.By annular slab 95, a plurality of blades 94 are interconnected along circular path, thereby annular slab 95 can form resistance, the outer shroud air-flow of prevention 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), due to a plurality of holes 51 that are provided with in side wall ring week of exit cone 5, 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, the upper peripheral edge border due to exit cone 5 can generate turbulent flow, therefore can to around granule produce disturbance; And if air-flow enters exit cone 5 by a plurality of holes 51 on exit cone 5 sidewalls, 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 process at this; the granule that is mingled with in 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 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.Be comparatively regular substantial cylindrical because this convolution is regional, therefore air-flow can form regular eddy flow in this convolution process, thus follow-up enter not too regular outlet chamber 11 in the time, can reduce the generation of turbulent flow, reduce the possibility of altering on air-flow, and then improve separating effect.

(8), at least part of ring grate bar of ring in grate 19 extends to the second annulus 72 of material-falling hopper flange 7, and is fixed on this second annulus 72 from the second top cover 22 of housing 2.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.

1, primary separation process

Mixture to be separated (comprising bulky grain, granule and gas) tangentially enters inlet chamber 10 from the admission line on dust removal machine top; form whirlwind; under the effect of inertia and centrifugal force; the gas that centrifugal force is less and granule mixture are positioned at the center; the bulky grain that centrifugal force is larger is positioned at periphery, thereby realizes primary separation.Bulky grain is deposited under Action of Gravity Field on the snail ring of inlet chamber 10 diapires 102, and the hole on the snail ring is blocked by baffle plate at this moment, thereby bulky grain is gathered on this snail ring.During discharging, this baffle plate is removed, isolated bulky grain falls into the periphery of housing 2 inner chambers by the arcuate socket 1021 on the snail ring, is deposited at last the bottom of housing 2, and the elementary blanking port by housing 2 bottoms enters the first collection ash can 13 through elementary material blanking tube 12.

(2), due to the diapire 102 of the inlet chamber 10 roof certain distance lower than centrifugal chamber 4, therefore make the bulky grain of the High Rotation Speed of separating reduce rotary speed in infall process, the bulky grain of separating is densification progressively if having time, can accumulate on the diapire 102 of inlet chamber 10, flow in 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 circular hole is larger, thereby also has more bulky grain can be trapped on snail ring between circular hole, is difficult to fall into the periphery of housing 2 inner chambers.The arc radius of arcuate socket 1021 can be large (even can be suitable with the size of snail ring), so the delay area between arcuate socket 1021 is less, thereby only has a small amount of bulky grain to be trapped on snail ring between arcuate socket 1021.Be gathered in the position of the outer peripheral edges of close snail ring due to bulky grain major part under centrifugal action, 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), be provided with the guided plate 14 of inclination in the inner chamber due to 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.

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 mixture (dust granule) is applied in larger centrifugal force, make granule carry 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 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 make gas to form more regular eddy flow, reduces turbulent flow) around stem stem 6, discharge by outlet chamber 11 and outlet pipe at last.

It is more than the second-order separation process of dry dust removal mode.If as indicated above, dust removal machine also is provided with liquid-jet device, 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, makes particle increase, and therefore can reduce it by the possibility of turbulent perturbation.

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