Specifically, selection makes the interval G1 between expanding face 15 and inclined-plane 21 become rotating cylinder main body 9 in specified operating
Inner peripheral surface and rotary barrel 23 outer peripheral surface between interval G2 1/3 or so (hereinafter referred to as normal space) spring it is normal
Several and number.
That is, so that the elastic force of one group of 18 entirety of disk spring and the pressing force of dewatered cake when specified operating are arranged in filter cake
Access 27 becomes the spring constant and number that the mode balanced in the state of normal space selects disk spring 37 out.
Here, if the moisture content of dewatered cake further decreases, the pressing force of dewatered cake is further increased, interval
G1 becomes larger than normal space, so that the area of filter cake drain passageway 27 increases.The area of filter cake drain passageway 27 increases, thus
Dewatered cake is more discharged, and the residence time of dewatered cake shortens.The moisture content of dewatered cake is from lower state as a result,
Return to higher state, i.e. original state.
In addition, the pressing force of dewatered cake reduces if the moisture content of dewatered cake increases, interval G1 becomes smaller than mark
Quasi- interval, so that the area of filter cake drain passageway 27 reduces.The area of filter cake drain passageway 27 reduces, thus the row of dewatered cake
Output is also reduced, and the residence time of dewatered cake increases.The moisture content of dewatered cake returns lower from higher state as a result,
State, original state.
That is, becoming the residence time corresponding with the moisture content of dewatered cake, to make the variation of the moisture content of dewatered cake
For minimum limit.
In addition, if there are the blocks of fibre composition, crystallization to be piled up in filter cake containing fibre composition, crystallization in hydrate
The case where drain passageway 27.In this case, the area of filter cake drain passageway 27 temporarily reduces, and discharge resistance increases, thus interior
Pressure increases, and the power of pressing spool 17 increases.At this point, the size of spool 17 and increased power is retreated to correspondingly axial side D1,
To which the area of filter cake drain passageway 27 increases.That is, the interval G1 between expanding face 15 and inclined-plane 21 is wider than normal space, thus
The width of filter cake drain passageway 27 broadens.Thus the fibre composition for being piled up in filter cake drain passageway 27, crystallization are removed.
After removing attachment, under the action of the elastic force of one group of disk spring 18, the area of filter cake drain passageway 27 restores
At normal space.
Next, being illustrated to the effect of the shape of the supporting mass 20 of present embodiment.
As described above, the bearing phosphor bodies 44 of the supporting mass 20 of present embodiment are cylindrical.Support phosphor bodies 44
The section shape semicircular in shape comprising axes O of the end of axial other side D2, the edge contacted with disk spring 37.
As shown in fig. 6, supporting mass 20 supports disk spring 37 from axial side D1.(a) institute of disk spring 37 from such as Fig. 6
The state shown is deformed into the state being compressed by as shown in (b) of Fig. 6, so that disk spring 37 and supporting mass 20 connect
Feeler degree changes.
That is, axes O and angle formed by wide diameter portion 38 (disk spring 37) and the axis at the C2 of contact point at the c1 of contact point
Line O changes with angle formed by wide diameter portion 38 (disk spring 37).As shown in fig. 7, contact point C1, C2 are mobile, and contact
Angle also changes.Here, at contact point C1, C2, flexible deformation slightly occurs for supporting mass 20, thus disk spring 37 with
Face contact occurs for supporting mass 20.At this point, in the case where the section shape comprising axes O of supporting mass 20 is semicircle shape, dish
Spring 37 and the contact area of supporting mass 20 do not change.
Next, as comparative example, as shown in figure 8, being square to the section shape comprising axes O of bearing phosphor bodies 44C
Shape, the outer peripheral surface F1 for supporting phosphor bodies 44C are orthogonal with the direction axial direction face F2 of other side D2 of bearing phosphor bodies 44C like that
Shape the case where be illustrated.
Similarly, the state shown in (a) such as Fig. 8 of disk spring 37 is deformed into as shown in (b) of Fig. 8 such situation
Such state, so that disk spring 37 and the contact angle of supporting mass 20C change.Here, in contact point C21, C22
Flexible deformation slightly occurs for place, supporting mass 20, so that face contact occurs for disk spring 37 and supporting mass 20.At this point, in supporting mass
In the case that the section shape comprising axes O of 20C is rectangular-shaped, the contact area S21 of disk spring 37 and supporting mass 20C,
S22 changes.
In this way, disk spring 37 deforms, change with the contact angle of supporting mass 20C, thus disk spring
The transmitting of 37 compressing force becomes unstable, so that back pressure becomes unstable.In addition, in the deformation of disk spring 37,
The crest line supported between the outer peripheral surface F1 and the face F2 towards axial other side D2 of phosphor bodies 44C is being contacted with disk spring 37
State lower slider, therefore it is larger to rub.The bearing side phosphor bodies 44C is thinned caused by generating because of friction as a result, disk spring 37
Deformed movement becomes to have some setbacks.
According to above embodiment, the position of supporting mass 20 to connect with disk spring 37 is formed as semicircle shape, thus logical
Cross the flexible of disk spring 37, even if the contact angle at the position that disk spring 37 connects with supporting mass 20 changes, friction
Coefficient, contact area are also constant all the time.As a result, in the deformation of disk spring 37, the friction of disk spring 37 and supporting mass 20
Become smaller, prevent 20 side of supporting mass because friction caused by be thinned, the deformed movement of disk spring 37 can be made smooth.As a result, can
The compressing force of disk spring 37 is enough set steadily to be transferred to spool 17, the back pressure that disk spring 37 can be made to generate is stablized.In addition,
The deformed movement of disk spring 37 can be made smooth.
In addition, by using disk spring 37 as the component for applying elastic force to spool 17, it can be with lower cost system
Make centrifugal dehumidifier 1.
In addition, since disk spring 37 is arranged in a manner of keeping aperture surface chimeric with the cylindrical portion 46 of spool 17, energy
It is enough to realize miniaturization.In addition, since disk spring 37 is not in contact with there are the component of rotation speed difference (such as rotating cylinders with itself
Body 23), therefore can prevent from wearing.
In addition, there is enough length on axial D since valve body core 17 has conus portion 45 and cylindrical portion 46,
The direction other than D in the axial direction can be prevented mobile.Even if for example discharge pressure generates deviation as a result, filter cake drain passageway 27
Any position of width in the circumferential is also uniform, and hydrate can equably be discharged.
In addition, can be prevented because of the weight inside outer barrel rotating cylinder 8 not since hydrate can equably be discharged
Abnormal vibrations caused by balancing.That is, can prevent since the hydrate in filter cake drain passageway 27 is uneven and right in the circumferential
The behavior in service of centrifugal dehumidifier 1 generates adverse effect.
More than, embodiments of the present invention are described in detail referring to attached drawing, but each structure in each embodiment
And their combination etc. is an example, without departing from the scope of spirit of the present invention, is able to carry out adding, omit, setting for structure
It changes and others changes.In addition, the present invention is not limited by embodiment, and only limited by the range that entitlement requests are protected.
