The effect of facing the micro mist removal device of present embodiment down describes.
When driving is connected in the air blast 93 of effuser 190; Shown in figure 14; Outer wall below annulus 150A is (the sidewall of urceolus 150; Overlapping with effuser 190 at least part on the direction of principal axis of the central shaft 141 of inner core 140) through the air 1 that effuser 190 attracts in the micro mist removal devices, below annulus 150A, forms the eddy flow 5A that flows as driving.At this moment; The inwall of annulus 150A below is (in the sidewall of inner core 140; Overlapping with effuser 190 at least part 144 on the direction of principal axis of the central shaft 141 of inner core 140) ventilation blocking-up portion 145 is set, therefore can suppresses air-breathing, obtain strong eddy flow 5A from the inwall of annulus 150A below.Again, ventilation blocking-up portion 145 is because to be arranged at full girth 144a, the 144b of inwall of annulus 150A below last, then can be not air-breathing at the last inwall below the annulus 150A of full girth 144a, 144b, can access stronger eddy flow 5A.And just as inlet 191 that kind that form to get into annulus 150A bottom, effuser 190 possesses the pipe sidewall 193 that gets into this annulus 150A bottom, therefore can reduce with the direction of rotation of eddy flow 5A rightabout air-breathingly, obtains stronger eddy flow 5A.
Again; Utilize the pipe arrangement of aspiration-type to carry, like Figure 15, shown in Figure 16, air 1 passes through inflow pipe 180 with the mist 3 (including micro mist 4) of particle 2; Tangentially flow into the doffing portion 143 interior (below of funnel-form space 140A) of inner core 140 from its sidewall; Along the inwall of the doffing portion 143 of inner core 140 while rotate rise get in tube position 142, rise entering filter 130 (top of funnel-form space 140A) while rotate along the inwall at the middle tube position 142 of inner core 140; Inwall along filter 130 rises while rotating, and arrives loam cake 170.At this moment, because the eddy flow 5A that below annulus 150A, forms is strong, the air-flow 6A of the mist 3 in the filter 130 forms the little strong helical form air-flow of lead angle.Again, the filter hole 131 that on the sidewall of filter 130, is provided with is the slotted hole on the central shaft 141 rectangular directions of length direction and inner core 140.On the other hand, in the mist 3 that flows along filter 130 spiral inner wall shapes, there is centrifugal force to work.Therefore, filter hole 131 makes in the mist 3 particle 2 following moving on the length direction of filter hole 131, and the air-flow 6A of the mist 3 in the filter 130 forms the littler helical form of lead angle.
The mist 3 of 1 unit, before stopping blower, along the inwall rotation of filter 130 on one side filter 130 in be detained on one side.Then, along the inner wall of the spiral filter 130 6A generate strong airflow flowing strong centrifugal force, the mixed gas of the particles 2 3 4 reliably and powder separated from the side of the filter 130? Inside and outside the wall.Can not pass filter hole 131 than filter hole 131 big particles 2, rest on the inboard of filter 130 sidewalls, be separated to the outside of filter 130 sidewalls than filter hole 131 little micro mists 4 through filter hole 131.At this moment, have from the filter 130 inside sidewalls air-flow 7A of flow air 1 laterally, therefore easily particle 2 is separated with micro mist 4 at filter hole 131.
Be separated to filter 130 sidewalls the outside, be the micro mist 4 of annulus 150A; By means of staying the air-flow 8A that this place makes helical form flow air 1; Descend while rotating; Arrive annulus 150A below,, tangentially flow out from the sidewall of the doffing portion 152 of urceolus 150 through effuser 190.That is to say, outside urceolus 150, flow out.The micro mist 4 that comprises in the air 1 that outside urceolus 150, flows out is reclaimed by dust collect plant 94, from the outlet of air blast 93 clean air 1 is discharged to the atmosphere.
Along filter 130 inwalls while rotate filter 130 be detained during, the particle 2 that is removed micro mist 4 falls when the driving of air blast 93 stops, and discharges to make-up machine 90 from the outlet 143a as the lower opening of the doffing portion 143 of inner core 140.Certainly, while along filter 130 inwalls rotate be detained during, the dust through filter hole 131 and plastic resin small pieces etc. are also removed as foreign matter with micro mist 4.Promptly begin blower 93 after accomplishing 1 micro mist removal processing like this, then carry out another micro mist and remove processing.
Like this, the micro mist removal device of present embodiment is handled the particle 2 of each Board Lot by handling in batches, removes micro mist 4 foreign matters such as grade from this particle 2.
When carrying out batch process; Driving time (pull up time) according to air blast 3 determines the time of particle 2 in filter 130 inwalls (filter plane) delay; Therefore in the micro mist removal device of present embodiment, less than the difference of the holdup time of causing because of shape as power that drives the eddy flow 5A that flows and filter hole.However, the particles 2 in the filter 130 is rotated, not by a predetermined orbital movement, but up and down, or a change in the inner wall of the filter 130 from the movement (the up and down, colliding particles 2, due to its counterproductive, and the distance between the inner wall of the filter 130 change).In this case, the filter hole 131 of present embodiment is a slotted hole, can suppress moving up and down of particle 2.Can suppress it and move up and down, suppress particle 2 exactly and collide each other.Because not collision (or make impact force little), the particle 2 that receives centrifugal force stably rotates by track at the inwall of filter 130.Then a strong swirl of the present embodiment will be stronger centrifugal 5A give particles 2, more stable particles 2 in the inner filter 130 at track rotation.Strong eddy flow 5A like this, as the filter hole 131 of slotted hole, the particle 2 and the time of contact of filter 130 inwalls are prolonged, can improve micro mist and remove efficient.In addition; The micro mist removal device of present embodiment; Be to put into from the device below as the particle 2 of process object, the type in that the particle that will handle 2 is removed below the device still also can form the outlet that the particle of handling 2 is set above installing; To put into from the device below as the particle 2 of process object, with the model (continuously processing type) of the particle of handling 2 from the removal of device top.Under such situation, mist 3 is long in the holdup time of filter 130 inwalls (filter plane), can improve the removal efficient of micro mist 4.
As stated, adopt present embodiment also can access the effect identical with embodiment 1.
In the micro mist removal device of present embodiment, also can be added on the central tube 100, strainer cover the 110, the 2nd inflow pipe (the 2nd inflow entrance) 120 that added in the micro mist removal device of embodiment 2 again.
As stated, embodiment 1～3 has represented the example that the present invention is desirable, but the invention is not restricted to this, in the scope that does not break away from its main idea, can do all distortion and implement.For example filter also can be the well-known filter that the filter hole that does not have the mist guide function is arranged at sidewall.Again, filter hole can not be a slotted hole also.Again, filter hole also can be with the free stream of making the mist that helical form flows along the filter inwall be directed to from than the direction of this free stream more near with the rectangular direction of inner core central shaft to 1 direction of the rectangular direction of inner core central shaft on slotted hole.In this case, filter hole forms the slotted hole that length direction is a channeling direction.
Again, in order inside and outside filter, to form spiral flow, about the closure of the effuser of the air of the inflow pipe of mist and admixed finepowder, will both tangentially be arranged at a sidewall these, any side gets final product.Among the present invention, on closure, connect effuser, so the closure of inflow pipe also can be the direction (the for example diametric(al) of inner core) beyond the closure.The effuser of the air that mixes about the inflow pipe of mist and admixed finepowder is in the axial position of inner core central shaft; As long as it is different; In this case, both are not overlapping also passable fully on the direction of principal axis of inner core central shaft, and it is also passable to overlap.Also have, under the situation of embodiment 3, the effuser of the inflow pipe of mist and the air of admixed finepowder also can be identical in the axial position of the central shaft of inner core.
Again, the micro mist removal device that embodiment 1～3 carries with the pipeline that is applicable to the powder body describes the present invention, and carries but go for that also multiple powder body is carried out pipeline, mixes simultaneously, removes the device of micro mist.
