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

1, primary separation process

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

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

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

(2) top cover, due to housing 2 is stepped, therefore bulky grain just falls in the first top cover 21 lower zone, the mixture of granule and gas then enters the region below the second top cover 22 further under wind-force effect, and then enters in centrifugal chamber 4 and be separated.That is, mixture in climbing process, the abatement of wind because space becomes large, thus be beneficial to bulky grain and fall under gravity, thus improve the separative efficiency of this primary separation process.

(3), junction and three junction sidewall and the first side wall between of the second sidewall of housing 2 respectively and between the 3rd sidewall and the 4th sidewall is all provided with arc transition plate, junction is made to form arc transition, thus suppress the formation of the turbulent flow in housing 2 inner chamber, improve separating effect.

(4) windward side face of inlet chamber 10 (namely near) of, ring grate 19 is provided with arc filter screen 20, therefore when needle rotor 3 does not rotate, the arc filter screen 20 that on ring grate 19, local is hung 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, thus maintains easily the parts of housing 2 inside.

2, the second-order separation process

The gas separated in primary separation process and short grained mixture enter centrifugal chamber 4, under needle rotor 3 High Rotation Speed drives, and High Rotation Speed thereupon, thus mixture is separated into granule and gas under centrifugal action.On the one hand, granule (dust granule) in mixture is applied in larger centrifugal force, granule is made to carry out outwards downward centrifugal motion, dust granule is caused to arrive on the sidewall of centrifugal chamber 4, so dust granule moves downward along centrifugal chamber 4 sidewall, fall in material-falling hopper 9, thus 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 chamber central of centrifugal chamber 4, forms downward strong eddy flow.When arriving centrifugal chamber 4 bottom, enter exit cone 5 inner, continue to do high speed circumnutation (be to make gas form more regular eddy flow in the effect of exit cone 5 and stem stem 6, reduce turbulent flow) around stem stem 6, discharge finally by outlet chamber 11 and outlet pipe.

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, then preferred semi-wet dedusting method can be adopted to carry out above-mentioned the second-order separation process.That is, after gas and short grained mixture enter centrifugal chamber 4, atomizer 17 sprays atomizing liquid grain (such as water), thus granule can assemble liquid grain surface, particle is increased, therefore, it is possible to reduce it by the possibility of turbulent perturbation.

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

(1) cylindrical void 41 of the interrupted distribution of annular, is formed by the bottom section of the sidewall of centrifugal chamber 4, therefore isolated granule can arrive the outside (space namely between centrifugal chamber and housing 2) of centrifugal chamber 4 in time by these long and narrow cylindrical voids 41, realizing further with while being separated of gas, originally the granule of High Rotation Speed can reduce its rotary speed significantly after cylindrical void 41, thus the granule arriving centrifugal chamber 4 outside can easily be deposited in material-falling hopper 9 under gravity, thus reach good separating effect.

(2), due to the diapire of centrifugal chamber 4 and the top (i.e. the upper peripheral edge of cylindrical portion 91) of material-falling hopper 9 in the central axial direction of centrifugal chamber 4 at a distance of certain distance, therefore between the diapire and the top of material-falling hopper 9 of centrifugal chamber 4, a longitudinal buffer district (namely defining slit buffer circle in the central axial direction of centrifugal chamber 4) is constructed, reduce further granule rotary speed, thus be deposited under gravity in material-falling hopper 9 more easily, reach good separating effect.

(3), the open top (i.e. the open top of cylindrical portion 91) of material-falling hopper 9 is greater than the bottom opening (the second opening of the diapire of centrifugal chamber 4 namely mentioned above) of centrifugal chamber 4.Therefore, on the one hand, a horizontal buffering area (namely edge and the direction of the central axis upright of centrifugal chamber 4 defining buffering area) is constructed between the open top and the bottom opening of centrifugal chamber 4 of material-falling hopper 9, reduce further granule rotary speed, thus be deposited under gravity in material-falling hopper 9 more easily, reach good separating effect; On the other hand, because material-falling hopper 9 open top is comparatively large, the granule therefore from centrifugal chamber 4 can be received in material-falling hopper 9 fully.

(4), material-falling hopper flange 7 is coated with annular oriffice 8.Annular oriffice 8 fully ensure granule through condition under, the probability that the air-flow in centrifugal chamber 4 permeates in material-falling hopper 9 can be reduced by forming resistance, thus reduce air-flow to the disturbance of granule sedimentation, granule can be deposited in material-falling hopper 9 more easily under gravity, reach good separating effect.

(5), the outer peripheral face in annular canister portion 93 is provided with some blades 94, the shape of blade 94 is roughly the tabular of inclination, and incline direction is consistent with flow rotation direction in centrifugal chamber 4.Preferably, multiple blade 94 is connected 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 that the outer peripheral face in the annular canister portion 93 of this material-falling hopper 9 is arranged can guide the swirl velocity of air-flow to transform to axial velocity, reduce air-flow to short grained disturbance, the short grained rotation intercepted in material-falling hopper 9 is risen.By annular slab 95, multiple blade 94 is annularly interconnected in path, thus annular slab 95 can form resistance, stop the outer shroud air-flow of relatively high pressure pass through to the interior zone of relatively low pressure and form turbulent flow, thus reduce air-flow further to short grained disturbance, improve separating effect.

(6) multiple hole 51 is provided with side wall ring week, due to exit cone 5, therefore the gas separated is when arriving centrifugal chamber 4 bottom, be positioned at the air-flow of exit cone 5 outside except entering except exit cone 5 from the upper peripheral edge of exit cone 5, most of air-flow can also enter exit cone 5 by the multiple holes 51 on exit cone 5 sidewall.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 disturbance can be produced to the granule of surrounding; And if air-flow enters exit cone 5 by the multiple holes 51 on exit cone 5 sidewall, then air-flow can enter exit cone 5 through hole 51 more lenitively in rotary course, reduce the generation of turbulent flow, thus 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 separated is when arriving centrifugal chamber 4 bottom; the air-flow being arranged in exit cone 5 outside progressively enters exit cone 5 in the process rotated up around exit cone 5; rotate up in process at this; the granule be mingled with in air-flow can obtain sedimentation under gravity; therefore more close to the top of exit cone 5, the granule be 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 the more short grained air-flow that is mingled with being positioned at initial stage fiaring cone 5 lower area from entering exit cone 5, improve separating effect further, 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 distance.Therefore between the roof and material-falling hopper flange 7 of outlet chamber 11, form region of circling round, circling round from exit cone 5 air-flow flowed out can in the continuous convolution of this convolution region relaying.Because this convolution region is in comparatively regular substantial cylindrical, therefore air-flow can form regular eddy flow in this convolution process, thus when follow-up entering in not too regular outlet chamber 11, can reduce the generation of turbulent flow, reduce the possibility that air-flow is altered, and then improve separating effect.

(8) at least part of ring grate bar, in ring 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 may be used for the welding location of the material-falling hopper 9 below material-falling hopper flange 7, controls welding deformation, and can ensure the axiality of centrifugal chamber 4, material-falling hopper flange 7 and material-falling hopper 9.

(2), because the diapire 102 of inlet chamber 10 is lower than the roof certain distance of centrifugal chamber 4, therefore the bulky grain of the High Rotation Speed separated is made to reduce rotary speed in infall process, the free progressively densification of the bulky grain separated, can accumulate on the diapire 102 of inlet chamber 10, but be unlikely to enter and flow in centrifugal chamber 4, thus 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 has the following advantages compared with existing circular hole.The aperture of circular hole can not too greatly (compared with the size of snail ring), and the delay area therefore between circular hole is comparatively large, thus also has more bulky grain can be trapped on the snail ring between circular hole, is difficult to the periphery falling into housing 2 inner chamber.The arc radius of arcuate socket 1021 then can comparatively greatly (even can be suitable with the size of snail ring), and the delay area therefore between arcuate socket 1021 is then less, thus on the snail ring only having a small amount of bulky grain to be trapped between arcuate socket 1021.Because bulky grain major part under centrifugal action is gathered in the position of the outer peripheral edge near snail ring, and the outer peripheral edge that arcuate socket 1021 can press close to snail ring is arranged, thus impel most of bulky grain to be smoothly through further periphery that arcuate socket 1021 falls into housing 2 inner chamber.

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

2, the second-order separation process

The gas being positioned at center separated in primary separation process and short grained mixture enter centrifugal chamber 4, under needle rotor 3 High Rotation Speed drives, and High Rotation Speed thereupon, thus mixture is separated into granule and gas under centrifugal action.On the one hand, granule (dust granule) in mixture is applied in larger centrifugal force, granule is made to carry out outwards downward centrifugal motion, dust granule is caused to arrive on the sidewall of centrifugal chamber 4, so dust granule moves downward along centrifugal chamber 4 sidewall, fall in material-falling hopper 9, thus 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 chamber central of centrifugal chamber 4, forms downward strong eddy flow.When arriving centrifugal chamber 4 bottom, enter exit cone 5 inner, continue to do high speed circumnutation (be to make gas form more regular eddy flow in the effect of exit cone 5 and stem stem 6, reduce turbulent flow) around stem stem 6, discharge finally by outlet chamber 11 and outlet pipe.

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, then preferred semi-wet dedusting method can be adopted to carry out above-mentioned the second-order separation process.That is, after gas and short grained mixture enter centrifugal chamber 4, atomizer 17 sprays atomizing liquid grain (such as water), thus granule can assemble liquid grain surface, particle is increased, therefore, it is possible to reduce it by the possibility of turbulent perturbation.

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