Supporting axis 36 forms ridge on its outer peripheral face, extend along left and right directions.Again, the right side of wall member 35 is fixed in the left part of supporting axis 36 with nut 38 by packing ring.Again, the right part of supporting axis 36 connects the right wall of shell 2, is fixed in the right wall of shell 2 with nut 39.
By means of this, movable wall 7 is fixing on shell 2 usually, by the loosening fixedly nut 39 of the right part of supporting axis 36, wall member 35 is slided on left and right directions simultaneously.Wall member 35 be formed at by sliding while the posture of keeping along above-below direction, making and vertical component effect 13 between the long-pending even variation of opening section of deadweight whereabouts portion.
Also have, the wall member 35 of movable wall 7 be it seems from the front, can slide in the scope on the right side of the right-hand member edge of vertical component effect 13 in the left side of the left end edge of the 2nd air introducing port 9.
The 2nd air introducing port 9 forms and it seems the below that is disposed at discharge duct 32 from the front, and is to be disposed at than the wall member 35 of movable wall 7 side of keeping right more, in the rear side inner surface of shell 2, it seems from the front roughly to form the circle that connects.Except that the air blast (not shown) of the 1st air introducing port 8,, connecting the air blast (not shown) of in shell 2, carrying air to use at the 2nd air introducing port 9.Each air blast (not shown) is independently controlled respectively.By means of this, can distinguish and independently control from the air output of the 2nd air introducing port 9 air-supplies and the air output of blowing from the 1st air introducing port 8.
Respectively removing acusector 41 is the pins that constitute with conductive materials such as metals, inserts the logical acusector inserting hole 16 that respectively removes respectively.Again, the front end that removes acusector 41 in left side keeps the configuration of slight gap opposite face above the upper end of the 1st platform 11, and the front end that removes acusector 41 on right side keeps the slight gap opposite face to dispose above the 2nd platform 12.Also have, also can be blown into ion wind and replace removing acusector 41.
Material is discharged the bottom setting that member 4 is connected in shell 2, and the below of complete covering shell 2.Again, material is discharged member 4 fronts and be it seems that formation is roughly platform shape, and its left and right sides wall tilts, and past more below opening section is long-pending more little.
Action to cleaning machine 1 describes below.
At first,, in shell 2, send into air, make air-flow takes place in the shell 2 from the 1st air introducing port 8 and the 2nd air introducing port 9 for cleaning machine 1 cleaning powder plastochondria.
The air of sending into from the 1st air introducing port 8 is introduced into the left wall that utilizes transfer member 5, shell 2, and the left wall of the rear wall of the antetheca of shell 2, shell 2 and material discharge member 4 separates the space of formation, blows out from the 1st ventilating opening 21 and the 2nd ventilating opening 26.That is to say the air-flow that the 1st air introducing port 8 takes place towards the 1st ventilating opening 21 and the 2nd ventilating opening 26.
The air past more right-hand deflection more downwards under the effect of air-deflecting panel 22 that blows out from the 1st ventilating opening 21.On the right side of the 1st ventilating opening 21, the bottom of opposite face configuration conflict member 6, therefore the bottom from the 1st ventilating opening 21 air that blows out and the member 6 that conflicts interferes.That is to say that the air-flow of air-deflecting panel 22 controls the 1st ventilating opening 21 makes it flow to conflict member 6.
On the other hand, the air that blows out from the 2nd ventilating opening 26 upwards blows to top-right exhaust apparatus 10 by the punching 28 of punch metal plate 27.That is to say that 27 controls of punch metal plate make the air flow direction exhaust apparatus 10 of the 2nd ventilating opening 26.
Again, the rear wall that the air of sending into from the 2nd air introducing port 9 is introduced into the antetheca of right wall, shell 2 of the horizontal component that utilizes wall member 35, discharge duct 32, shell 2 and shell 2 separates the space of formation, around below, pass through between vertical component effect 13 and the wall member 35 from the below to wall member 35.That is to say that the 2nd air introducing port 9 takes place to blow upward from the below, by the air-flow between vertical component effect 13 and the wall member 35.
And the air that blows out from the 2nd ventilating opening 26 and between each fin 33, be blown into discharge duct 32 from the air that the 2nd air introducing port 9 is sent into, from exhaust outlet 31 rows to the outside.That is to say that exhaust apparatus 10 is discharged to the outside with the air-flow of the 1st air introducing port 8.
The air-flows that take place in the shell 2 be divided into from the 1st ventilating opening 21 flow to conflict members 6 air-flow, from the 2nd ventilating opening 26 flow to the air-flow of exhaust apparatus 10, these three kinds of air-flows of air-flow by flowing to exhaust apparatus 10 between vertical component effect 13 and the wall member 35 upward from the below.
Then, importing member 3 by material introduces the mixture of powder body and dust in the shell 2.
The mixture that is introduced in the shell 2 is at first guided the upper end of the 1st platform 11 into by conflict member 6.
So mixture tilts by means of the 1st platform 11 and flows to the air-flow of conflict member 6 from the 1st ventilating opening 21, Yi Bian quicken below oblique to the right, Yi Bian impact to the bottom of impact structure 6.Peel away with the dust that physics mode will be attached to the powder body with this.
Then, the mixture of shock member 6 is drawn towards the 2nd platform 12 upper ends.
So mixture is exposed to from the 2nd ventilating opening 26 and flows to the air-flow of exhaust apparatus 10.By means of this, mixture is separated into low weight dust and heavier powder body.
At this moment, the Heavy Weight of the weight ratio dust of powder body under the many situation, have only dust to be scrolled up by air-flow, be sent to exhaust apparatus 10, be discharged to the outside.
On the other hand, above-mentioned is the big situation of weight of the weight ratio dust of powder body, but under the smaller situation of the difference of the weight of the weight of dust and powder body, sometimes the powder body also can be scrolled up by air-flow with dust.
In this case, compare the easier and then air-flow of low weight dust with heavier powder body.Therefore, dust can with air-flow from fin 33 tops in going into discharge duct 32, from exhaust outlet 31 row to the outside.On the other hand, the powder body relatively is not easy and then air-flow, therefore can not walk around fin 33 as dust and enter in the discharge duct 32, falls but can clash downwards with fin 33.That is to say that fin 33 allows dust to enter in the discharge duct 32, limits the powder body simultaneously and enters discharge duct 32.
Also have, the mixture by the 1st platform 11 and the 2nd platform 12 in the process of passing through with the preceding end in contact of removing acusector 41.By means of this, have at powder body and dust under the situation of static and the static of powder body and dust can be removed.
And, then falling between from top to bottom by vertical component effect 13 and movable part 7 under the effect of deadweight at the powder body of the 2nd platform 12 and dust separation.
At this moment, the powder body be exposed to from the below upward by between vertical component effect 13 and the wall member 35 to exhaust apparatus 10 airflow flowing.That is to say that in deadweight whereabouts portion, the throughput direction of powder body is opposite with airflow direction.
By means of this, the dust of failing to remove at the 2nd platform 12 can be separated with the powder body, finish the cleaning of powder body.
Powder body after the cleaning is discharged member 4 by material and is collected, and is contained in the not shown containers.And thereafter, the powder body after the cleaning is used in processing and forming.
Also have, in above-mentioned example, form the gap between the antetheca of transfer member 5, discharge duct 32 and movable wall 7 and shell 2 or the rear wall, in this gap, the seal member S that the restriction air communication is crossed is set on the position of regulation.

If adopt this cleaning machine 1, then the air-flow that flows to the 1st platform 11 from the 1st air introducing port 8 flows to conflict member 6 under the control of the air-deflecting panel 22 of the 1st platform 11.Again, the air-flow that flows to the 2nd platform 12 from the 1st air introducing port 8 flows to exhaust apparatus 10 under the control of the punch metal plate 27 of the 2nd platform 12.
That is to say, when the 1st air introducing port 8 air-flow is taking place, at 11 air-flows that conflict member 6 takes place to flow to of the 1st platform, at 12 air-flows that flow to exhaust apparatus 10 of the 2nd platform.
Therefore, at first, mixture is drawn towards the 1st platform 11, impacts to conflict member 6 by means of the air-flow that flows to conflict member 6 simultaneously.By means of this, peel off with the dust that physics mode will be attached on the powder body.
Then, the mixture of carrying to the 2nd platform 12 from the 1st platform 11 is drawn towards the 2nd platform 12, is exposed to the air-flow that flows to exhaust apparatus 10 simultaneously.By means of this, mixture is separated into low weight dust and heavier powder body, and air-flow is only carried dust to exhaust apparatus 10.
Consequently, can from the mixture of powder body and dust, remove dust expeditiously.
If adopt this cleaning machine 1,, the member 6 that conflicts relatively is set with the 1st ventilating opening 21 then at the 1st platform 11 again.Therefore can utilize the air-flow that flows to conflict member 6, and the powder body be quickened, it is collided with the member 6 that conflicts really by means of the inclination of the 1st platform 11.
Again,, utilize it, with speed conveying more slowly, simultaneously it is exposed in the air-flow that flows to exhaust apparatus 10 in the long time powder body than the little inclination of the 1st platform inclination degree at the 2nd platform 12.
Therefore,, can peel off dust from the powder body, can dust be separated with the powder body with higher efficient at the 2nd platform 12 with higher efficient at the 1st platform 11.
Again, if adopt this cleaning machine 1, then at deadweight whereabouts portion (vertical component effect 13 of transfer member 5, the wall member 35 of movable wall 7 and they between), the powder body under the effect of deadweight, fall be exposed to simultaneously from below the air-flow above flowing to.
Therefore, the powder body to fall direction opposite with the throughput direction of removed dust.
Consequently, can further be separated in dust and the powder body that to remove in the 2nd platform 12.
Again, if adopt this cleaning machine 1, then by movable wall 7 is slided, the opening section that can evenly change deadweight whereabouts portion is long-pending.
Therefore, do not change air quantity,, just can evenly change the air quantity of the per unit sectional area of the air-flow that amasss by opening section in whole deadweight whereabouts portion as long as movable wall 7 is slided from the 2nd platform 12.
Consequently, can separate with higher efficient.
Again, if adopt this cleaning machine 1, then exhaust outlet 31 is deflated pipeline 32 around it and surrounds, and at discharge duct 32 a plurality of fins 33 is set.
Therefore, the dust that separates from the powder body can be walked around fin 33 by means of the air-flow that flows to exhaust apparatus 10 and enter discharge duct 32 from the top, be sent to exhaust outlet 31 from discharge duct 32.
On the other hand, be sent to exhaust apparatus 10,, enter discharge duct 32 and exhaust outlet 31 can be restricted also owing to impact fin 33 even the powder body flows to the air-flow of exhaust apparatus 10.
Consequently, the powder body can be stayed and only dust be removed from exhaust apparatus 10 simultaneously.
Again,, then, make it relative with the 2nd platform 12, so under the charged situation of powder body and dust, can remove the static of powder body and dust with the 1st platform 11 owing to be provided with to remove acusector 41 if adopt this cleaning machine 1.
Therefore even under the situation that powder body and dust attract each other by means of static, also can easily peel off dust from the powder body.
Again, if adopt this cleaning machine 1, then the 1st air introducing port 8 and the 2nd air introducing port 9 are independently controlled air output respectively.
Therefore can easily control air-flow according to the kind of powder body and dust.
Again, if adopt this cleaning machine 1, then between the antetheca of shell 2 or rear wall and the 1st platform the 11, the 2nd platform 12, discharge duct 32, vertical component effect 13 and wall member 35, form the gap that the air communication that makes the 1st air introducing port 8 and the 2nd air introducing port 9 is crossed, at the 1st platform the 11, the 2nd platform 12, discharge duct 32, vertical component effect 13 and wall member 35, the seal member S that is disposed at the gap is set.
And seal member S controls the air-flow that flows to the gap from the 1st air introducing port 8 and the 2nd air introducing port 9.
Therefore, by means of the seal member S between shell 2 and the discharge duct 32, can block from the 2nd air introducing port 9 and flow to the air-flow of discharge duct 32 by Clearance Flow.
Again, at the 1st platform the 11, the 2nd platform 12, vertical component effect 13 and wall member 35, keep between the 1st platform the 11, the 2nd platform 12, vertical component effect 13 and wall member 35 and shell 2, seal member S being set at interval, therefore can control air-flow by the gap between the 1st platform the 11, the 2nd platform 12, vertical component effect 13 and wall member 35 and the shell 2, can prevent powder body and dust be deposited near the inner surface of the shell 2 gap, the gap and gap near on the angle etc. of each parts formation.
