In the sidewall of urceolus 150; The central shaft 141 of inner core 140 axially on the sidewall of the below (doffing portion 152) of the overlapping urceolus 150 of the sidewall of the middle part of the ratio filter 130 of inner core 140 inner core 140 below more (middle tube portion 142) on; The air 1 (, flowing into the air 1 of the admixed finepowder 4 of the annulus 150A between the sidewall (sidewall of the sidewall of top cylinder portion 151 and doffing portion 152) of sidewall (sidewall of the sidewall of filter 130 and middle tube portion 142) and urceolus 20 of inner cores 140 in the inner core 140) that setting makes admixed finepowder 4 through each filter hole 131 from this tangentially flow to urceolus 150 external applications flow export, be effuser 190.This effuser 190 is a straight tube, and the inlet 191 of effuser 190 all forms circle with outlet 192.The pipe sidewall 193 (with reference to Figure 23 B) of the annulus 150A bottom between the sidewall (middle tube portion 142) that effuser 190 possesses the middle part that gets into inner core 140 and the sidewall of the bottom (doffing portion 152) of urceolus 150 forms annulus 150A between the sidewall (sidewall of the sidewall of filter 30 and middle tube portion 142) of entering inner core 140 and the sidewall of urceolus 150 (sidewall of top cylinder portion 151 and time with the sidewall of portion 152), is the inlet 191 of the bottom of the annulus 150A between the sidewall of bottom (doffing portion 152) of sidewall and urceolus 150 at middle part (middle tube portion 142) of inner core 140.

Effuser 190 and the base plate 152a (bottom surface of urceolus 150: all gapped the bottom surface of annulus 20A), but very close to each other then better in the present embodiment, between the sidewall of effuser 190 and urceolus 150 (outer wall of annulus 150A).The opening shape of the inlet 191 of effuser 190 is expressed as circle in the present embodiment, but can also can be rectangle for circle.The inlet 191 of effuser 190 is a rectangle, and between the sidewall of urceolus 150 and and base plate 152a between all very close to each other be optimal.

Central part at platen 160; The circular through hole 161 of the roughly the same diameter of lower opening (lower opening of doffing portion 143) of setting and inner core 140; Inner core 140 is holded up from the edge of the through hole 161 of platen 160; The lower opening of inner core 140 is opened to the lower face side of platen 160, forms the outlet 143a of the particle 2 of having removed micro mist 4.

Inner core 140 is to lower end open row outlet 143a; Formation is connected in the funnel-form space 140A of the inflow pipe 180 of lower sidewalls, and urceolus 150 forms the annulus 150A of the effuser 190 that is connected in lower sidewalls around the funnel-form space 140A of inflow pipe 180 above more.The sidewall of the borderline inner core 140 of these funnel-form space 140A and annulus 150A, be in the sidewall of sidewall and middle tube portion 142 of filter 130; A plurality of filter holes 131 that the sidewall of filter 130 is provided with by means of this place are connected funnel-form space 140A and lead to annulus 150A, the sidewall cut-out funnel-form space 140A of middle tube portion 142 and the ventilation between the annulus 150A.

Like Figure 19, shown in Figure 20, the middle tube portion 142 of inner core 140, doffing portion 143, be wholy set in platen 160 with the doffing portion 152 of urceolus 150.When the micro mist removal device of assembling present embodiment, on the flange 142a that the sidewall upper at the middle tube position 142 of inner core 140 is provided with, overlap the flange 130a that the side wall lower ends of filter 130 is provided with, the middle tube position 142 of inner core 140 is uploaded and is put filter 130.

Again; On the flange 152b that the sidewall upper of the doffing portion 152 of urceolus 150 is provided with; Through the top cylinder portion 151 that the lower liner 200 of ring-type is installed urceolus 150, liner 201 on covering ring-type in the top cylinder portion 151 of this urceolus 150 is installed loam cake 170 on inner core 140 and urceolus 150.At this moment filter 130 is sandwiched between the middle tube position 142 of loam cake 170 and inner core 140.Again, the top cylinder portion 151 of urceolus 150 is clipped between the doffing portion 152 of loam cake 170 and urceolus 150 through last lower liner 201,200.The top opening of inner core 140 (the top opening of filter 130) is closed with loam cake 170 integral body with the top opening (the top opening of top cylinder portion 151) of urceolus 150.

The a plurality of bolts 202 that make two-end part possess screw pass between loam cake 170 and the flange 152b; From the upper surface of loam cake 170 upper end tightening nuts 203 to each outstanding bolt 202 of top; From the lower surface of the flange 152b lower end tightening nuts 203 of each outstanding bolt 202 downwards; Utilize loam cake 170 that filter 130 is anchored on the middle tube position 13 of inner core 140, top cylinder portion 130 is anchored on the doffing portion 152 of urceolus 150, installation.At this moment, cause distortion or crackings such as the filter 130 of loam cake 170, inner core 140, the top cylinder portion 151 of urceolus 150,, sandwich the tubular liner 204 of outer embedding between loam cake 170 and the flange 152b at each bolt 202 in order to prevent excessive tightness.

Like this, take off loam cake 170 and just can replace filter.Again, clean under the situation such as micro mist removal device, can be decomposed into global facility, filter 130, the top cylinder portion 151 and the loam cake 170 of urceolus 150 of doffing portion 152 and platen 160 of middle tube portion 142 and the doffing portion 143 and the urceolus 150 of inner core 140.

The material that comprises the inner core 140, urceolus 150, platen 160, loam cake 170 etc. of filter 130 can use metal materials such as steel plate that general structure uses or corrosion resistant plate.In this case, the top cylinder portion 151 of urceolus 150 preferably uses transparent materials such as acrylic resin, Merlon, glass.Loam cake 170 uses transparent material then better.

Top cylinder portion 151 visualizations that so just can see through urceolus 150 from the outside of micro mist removal device are at the annulus 150A shape air-flow 8A with air 1 admixed finepowder 4 that flow in the shape of a spiral.Can see through loam cake 170 from the top of micro mist removal device again, Visual Confirmation is the 140A air-flow 6A of the mist 3 that flows of shape in the shape of a spiral in the funnel-form space, particularly can confirm the air-flow 6A of the mist 3 in filter 130.Like this, can see through the top cylinder portion 151 and the loam cake 170 of urceolus 150, see the whole inside of micro mist removal device, confirm the disposition of micro mist removal device from the outside of micro mist removal device.

The micro mist removal device of present embodiment; Replace the micro mist removal device of embodiment 1 and embodiment 2, make-up machine 90 is set, inflow pipe 180 is connected in the storagetank 92 of particle 2 through flexible pipe or pipe arrangement; Through flexible pipe or pipe arrangement effuser 190 being connected in provides kinergety or improves on the suction inlet as the air blast 93 of fluid machinery of its pressure air 1; Batch process is handled the particle 2 of each unit, removes micro mist 4 foreign matters such as grade from this particle 2.When the micro mist removal device of present embodiment is arranged at make-up machine 90, take off raw material supplying hopper 91, use through platen 160 vertical settings (being obliquely installed sometimes) at its connector.Between effuser 190 and the air blast 93 dust collect plant 94 is set.

At first, the micro mist removal device of reference example shown in Figure 24 the shape of the filter hole 410 that on filter 400 sidewalls, is provided with, possesses the structure identical with the micro mist removal device of present embodiment.Structure identical with the micro mist removal device of present embodiment among Figure 24 is marked with identical symbol.Shown in figure 24, the filter hole that is provided with on filter 400 sidewalls of the micro mist removal device of reference example 410 is for circular, therefore do not possess the such guide function of filter hole 131 of the micro mist removal device of present embodiment.

The micro mist removal device of the micro mist removal device of Figure 22, present embodiment shown in Figure 23 and reference example shown in Figure 24 in case the both is the air blast 93 that is connected in effuser 190 when starting, just begins to carry out the aspiration-type pipe arrangement and carries.Utilize this aspiration-type pipe arrangement to carry; The mist 3 of air 1 and particle 2 (also having micro mist 4); Through inflow pipe 180, flow into along tangential direction from this sidewall in the doffing portion 143 of inner core 140 (bottom of funnel-form space 140A), along the doffing portion 143 inwalls rotation of inner core 140 on one side rise on one side; Tube portion 142 in the entering is on one side along middle tube portion's 142 inwalls rotation rising on one side.In the present embodiment, get into filter 130 (top of funnel-form space 140A), in reference example, get into filter 400 (top of funnel-form space 140A), along each filter 130,400 inwalls rotation on one side rise on one side, loam cake 170 arrived.At this moment; Because the filter hole 410 that is provided with on the sidewall of reference example filter 400 is for circular; Do not have the such guide function of filter hole that the filter 130 of present embodiment is provided with 131, so the air-flow of the mist 3 that flows of the inwall along inner core 140 of reference example forms the free stream 5A that is not directed to (control).That is to say that becoming filter hole 131 guiding objects in the present embodiment is the free stream 5A of mist 3, the air-flow along the mobile mist 3 of inner core 140 inwalls in the present embodiment forms the control air-flow 6A by filter hole 131 guiding (control).Guide effect (being transformed to control air-flow 6A from the free stream 5A of mist 3) to filter hole 131 will be narrated below.

The mist 3 of 1 unit, before stopping blower 93, along the inwall rotation of filter 130,400 on one side filter 130,400 in be detained on one side.At that time, along the inwall of filter 130,400 the air-flow 6A, the strong action of centrifugal force that 5A produces of the mist 3 that flows of shape in the shape of a spiral, make particle 2 and micro mist 4 in the mist 3 be located away from the interior outside of the sidewall of filter 130,400 reliably.Can not pass filter hole 131,410 than filter hole 131,410 big particles 2; Rest on the inboard of filter 130,400 sidewalls, be separated to the outside of filter 130,400 sidewalls than filter hole 131,410 little micro mists 4 through filter hole 131,410.At this moment, have from filter 130, the 400 inside sidewalls air-flow 7A of flow air 1 laterally, therefore easily particle 2 is separated with micro mist 4 at filter hole 131,410.

Be separated to filter 130,400 sidewalls the outside, be the micro mist 4 of annulus 150A; Locate the air-flow 8A of shape flow air 1 in the shape of a spiral by means of staying this; 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 130,400 inwalls while rotate filter 130,400 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 130,400 inwalls rotate be detained during, the dust through filter hole 131,410 and plastic resin small pieces etc. are also removed as foreign matter with micro mist 4.Accomplish 1 time micro mist like this and remove and promptly begin blower 93 after handling, the micro mist that then carries out another is removed and is handled.

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.

The effect of facing the filter hole 131 of present embodiment down describes.

Shown in figure 22, are length direction slotted holes on the right angle orientation of the central shaft 141 of inner core 140 at the filter hole 131 that is provided with on filter 130 sidewalls.On the other hand, centrifugal force to along the inwall of filter 130 in the shape of a spiral the mist 3 that flows of shape work.Therefore; Filter hole 131 makes the particle 2 in the mist 3 move along the upward following of length direction of filter hole 131; Will along the inwall of filter 130 in the shape of a spiral the free stream 5A of the mist 3 that flows of shape to the length direction of filter hole 131, be the right angle orientation guiding of the central shaft 141 of inner core 140; Can know from Figure 22, Figure 24, the free stream 5A of the mist 3 in the filter 130 is transformed to lead angle than its littler control air-flow 6A.

When carrying out batch process; Driving time (pull up time) according to air blast 93 determines the time of particle 2 in filter 130 inwalls (filter plane) delay; Therefore in the micro mist removal device of the micro mist removal device of present embodiment and reference example, less than the difference of the holdup time of causing because of difference as filter hole 131,410.However, the particles 2 in the filter rotates within 130,400, not according to a predetermined track move, but the up and down, or a change in the inner wall of the filter distances 130,400 (due to down, particles 2 collide with each other due to their side effects, and the distance between the inner wall of the filter change 130,400).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.Like this, the filter hole 131 as slotted hole can prolong the time that particle 2 contacts with filter plane.Therefore can improve the efficient of removing micro mist." holdup time of prolongation on filter plane " this effect, expressing with another kind of expression way is exactly " prolonging the time that contacts with filter plane ".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, in the type that the particle that will handle 2 is removed below the device, still also can be through form the outlet that the particle of handling 2 is set above installing; The model (processing type continuously) that the particle of handling 2 is removed from the device top will be put into as the particle 2 of process object from the device below.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.

Here; Be arranged at the filter hole 131 on the sidewall of filter 130; So long as length direction than along the inwall of filter 130 in the shape of a spiral the free stream 5A of the mist 3 that flows of shape flow direction a little near with the right angle orientation of inner core 130 central shafts 11 on slotted hole; Just can the free stream 5A of the mist 3 in the filter 130 be transformed to the spiral helicine control air-flow 6A littler than its lead angle; Can make the holdup time of mist 3 on filter plane longer than the holdup time of free stream 5A; But at the filter hole that is provided with on the sidewall of filter 30 131 are length direction slotted holes on the right angle orientation of the central shaft 141 of inner core 140; Therefore can the free stream 5A of the mist 3 in the filter 130 be transformed to the spiral helicine control air-flow 6A littler than its lead angle, can make the holdup time of mist 3 on filter plane more much longer than free stream 6A.

Again; The sidewall of filter 130 when the central shaft 141 of inner core 140 is on the plumb line direction, forms along the downward more narrow more circular platform type of plumb line direction; The filter hole 131 that is provided with on these filter 130 sidewalls; More near the central shaft 141 of inner core 140, the probability that particle 2 touches the bottom in filter hole 131 increases, and can bring into play the guide function of filter hole 131 effectively than the top in the bottom of length direction.

The micro mist removal device of present embodiment; As the guider that is arranged at filter 130; Just will along the inwall of filter 130 in the shape of a spiral the free stream 5A of the mist 3 that flows of shape guide into from than the direction of this free stream more near with central shaft 141 right angle orientation of inner core 140 to the guider of 1 direction of the angle field θ of central shaft 141 right angle orientation of inner core 140; Can replace filter hole 131; Adopt the 1st slotted hole 501 shown in Figure 11 and the 2nd slotted hole 502, thrust 32 shown in Figure 10, also can adopt groove in addition.

In addition, when the sidewall of filter 130 extends to effuser 190 position overlapped at the direction of principal axis of the central shaft 141 of inner core 140, in the sidewall of filter 130; On the direction of principal axis of the central shaft 141 of inner core 140 with the overlapping part of effuser 190 on the air 1 that passes through of filter hole 131; Make annulus 150A in the shape of a spiral the air-flow 8A of shape flow air 1 die down, along the inwall of filter 130 in the shape of a spiral the air-flow 6A of the mist 3 that flows of shape also die down, the removal efficient of micro mist 4 reduces; But in the micro mist removal device of present embodiment; Shown in Figure 19, Figure 22, Figure 23 B, in the sidewall of inner core 140, overlapping with effuser 190 at least part on the direction of principal axis of the central shaft 141 of inner core 140; In order to block ventilation; The ventilation blocking-up portion (sidewall of middle tube portion 142) of atresia is set, therefore, can improves the efficient of removing micro mist 4 along the inwall of the filter 130 air-flow 6A grow of the mist 3 that flows of shape in the shape of a spiral.

Again; The inlet 191 of effuser 190 and the outlet of inflow pipe 180 182 are during equally along the sidewall opening of inner core 140; The soakage of the rightabout air 1 of the direction of rotation of the air-flow 8A of shape flow air 1 is many in the shape of a spiral at annulus 150A; Therefore annulus 150A in the shape of a spiral the air-flow 8A of shape flow air 1 die down, finally along filter 30 inwalls in the shape of a spiral the air-flow 6 of the mist 3 that flows of shape also die down, remove the inefficient of micro mist 4; But in the micro mist removal device of present embodiment; Shown in Figure 23 B, effuser 190 has the pipe sidewall 183 of the annulus 150A between the sidewall of the sidewall that gets into inner core 140 and urceolus 150, thus in annulus 150A the air-flow 8A grow of shape flow air 1 in the shape of a spiral; Finally, the efficient of removing micro mist 4 is risen along the inwall of the filter 130 also grow of air-flow 6A of the mist 3 that flows of shape in the shape of a spiral.

As stated, present embodiment also can access the effect identical with embodiment 1.

In the micro mist removal device of present embodiment, also can be attached to central tube 100, strainer cover 110 and the 2nd inflow pipe (the 2nd inflow entrance) 120 that adds in the micro mist removal device of embodiment 2 again.

As stated; In embodiment 1～3; With being suitable for the micro mist removal device of carrying as the well-known aspiration-type pipeline of powder body the present invention's (the 1st～the 4th invention) is illustrated; But the present invention is not limited to this, in the scope that does not break away from its main idea, can carry out implementing after the various distortion.For example can be suitable for as the well-known pressure sending type pipeline of powder body and carry, also can be suitable for the pipeline conveying of carrying gas as serving as with nitrogen, carbon dioxide.Again, embodiment 1～3 usefulness is carried out the pipeline conveying to a kind of powder body, and the device of removing micro mist describes the present invention, but the present invention also can be suitable for as multiple powder body being carried out the pipeline conveying, simultaneously it is mixed, the device of removal micro mist.

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.About the effuser of the air of the inflow pipe of mist and admixed finepowder axial position at the 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.
