Below the course of work of integrated separation machine mentioned above is described.

1, primary separation process

Mixture to be separated (comprising larger pieces of material, bulky grain, granule and gas) enters 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 grate bar, under Action of Gravity Field, along bar, glides and 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 discharge port discharging, and is delivered to precalculated position by 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, the centrifugation of aggravation larger particles outside centrifugal chamber 4.

(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 further enters the region below the second top cover 22 under wind-force effect, and then enters in centrifugal chamber 4 and carry out separation.That is to say, mixture is in climbing process, and because space becomes the large and abatement of wind, thereby be beneficial to bulky grain falls under Action of Gravity Field, thereby improves the separative efficiency of this primary separation process.

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

(4), on the windward side of ring grate 19 (i.e. the face of close inlet chamber 10), be provided with arc filter screen 20, 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.While arriving 4 bottom, centrifugal chamber, enter exit cone 5 inside, around stem stem 6, 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), finally by outlet chamber 11 and outlet pipe, discharge.

It is more than the second-order separation process of dry dust removal mode.If as described above, integrated separation machine is also 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, at gas and short grained mixture, enter behind centrifugal chamber 4, atomizer 17 ejection atomizing liquid grains (for example water), thus granule can be assembled liquid grain surface, and particle is increased, 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 distributing 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 gas separated 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 good separating effect.

(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 in the central axial direction in centrifugal chamber 4 at a distance of certain distance, therefore between the diapire in centrifugal chamber 4 and the top of material-falling hopper 9, construct Liao Yige longitudinal buffer district (having formed slit buffer circle in the central axial direction in centrifugal chamber 4), further reduced granule rotary speed, thereby under Action of Gravity Field, be deposited in material-falling hopper 9 more easily, reach good 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 (being the second opening of the diapire in centrifugal chamber 4 mentioned above) in centrifugal chamber 4.Therefore, on the one hand, between the open top of material-falling hopper 9 and the bottom opening in centrifugal chamber 4, constructing a horizontal buffering area (along having formed buffering area in the direction vertical with the central axis in centrifugal chamber 4), further reduced granule rotary speed, thereby under Action of Gravity Field, be deposited in material-falling hopper 9 more easily, reach good 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 material-falling hopper 9 fully.

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

(5), be provided with some blades 94 on the outer peripheral face of annular canister portion 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 if some flows to material-falling hopper 9 from the air-flow in centrifugal chamber 4 by annular oriffice 8, the blade 94 arranging on the outer peripheral face of the annular canister portion 93 of this material-falling hopper 9 can guide the swirl velocity of air-flow to transform to axial velocity, reduce air-flow to short grained disturbance, the short grained rotation intercepting 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 produce disturbance to granule around; And if air-flow enters exit cone 5 by a plurality of holes 51 on exit cone 5 sidewalls, air-flow can enter exit cone 5 through hole 51 more lenitively in rotary course, reduce the generation of turbulent flow, thereby reduce short grained disturbance around, 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 rotating up around exit cone 5; at this, rotate up in process; the granule being mingled with in air-flow can obtain sedimentation under Action of Gravity Field; therefore more approach the top of exit cone 5, the granule being mingled with in air-flow is fewer.Therefore, hole 51 is only 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 between the roof of outlet chamber 11 and material-falling hopper flange 7, form convolution region, the air-flow flowing out from exit cone 5 convolutions can continue to circle round this circles round region.Because this convolution region is comparatively regular substantial cylindrical, therefore air-flow can form regular eddy flow in this convolution process, thus follow-up enter not too regular outlet chamber 11 in 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, for the welding location of the material-falling hopper 9 of material-falling hopper flange 7 belows, be controlled 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 center; the bulky grain that centrifugal force is larger is positioned at periphery, thereby realizes primary separation.Bulky grain is deposited on the snail ring of inlet chamber 10 diapires 102 under Action of Gravity Field, and now the hole on snail ring is blocked by baffle plate, 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 snail ring, is finally deposited to 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.

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

(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 separated 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, but be unlikely to enter, flow in centrifugal chamber 4, thereby also can reduce the wearing and tearing of bulky grain to centrifugal chamber 4.

(3) hole, on snail ring is arcuate socket 1021, and arcuate socket 1021 is compared and had the following advantages with existing circular hole.The aperture of circular hole is large (comparing with the size of snail ring) too, so the delay area between circular hole is larger, thereby also have more bulky grain can be trapped on the 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 the snail ring between 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 impel most of bulky grain to be smoothly through the periphery that arcuate socket 1021 falls into housing 2 inner chambers.

(4) in the inner chamber, due to housing 2, be provided with the guided plate 14 of inclination, the bulky grain therefore falling 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 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.While arriving 4 bottom, centrifugal chamber, enter exit cone 5 inside, around stem stem 6, 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), finally by outlet chamber 11 and outlet pipe, discharge.

It is more than the second-order separation process of dry dust removal mode.If as described above, dust removal machine is also 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, at gas and short grained mixture, enter behind centrifugal chamber 4, atomizer 17 ejection atomizing liquid grains (for example water), thus granule can be assembled liquid grain surface, and particle is increased, 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:

Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
