Embodiment
Below, as the rotary processor of the preferred embodiment of the present invention, the decanting centrifuge of take describes as an example.But, be not, by the mode of execution of following explanation, technical scope of the present invention is done to any limited interpretation.
Fig. 1 means the overall structure of the centrifugal separator of present embodiment.In Fig. 1, as one of centrifugal separator, exemplify vertical depressor 1.Depressor 1 possesses the rotating cylinder 2 as solid of rotation.Rotating cylinder 2 is solid of rotation that inside is supplied to the roughly tubular of processed liquid, to processed liquid, gives the centrifugal force for solid-liquid separation.Rotating cylinder 2 is configured in the housing 3 as exterior body, by being configured in the outer drive motor as drive unit 31 of housing 3, can be rotated around vertical axis.
Upper side at rotating cylinder 2 disposes the disc element 21 that is called front hub (front hub), is formed with exhaust port (parting liquid exhaust port) 21a that discharges parting liquid on this disc element 21.On the other hand, be formed with the exhaust port (solid exhaust port) 22 of the solid that discharge separates in the lower side of rotating cylinder 2.In addition, be supported in the linking department 21c of the upper opening section that connects housing 3 as the axle 21b axle of the running shaft of rotating cylinder 2, be configured to the end of the axle 21b of transmission of power outside extending to housing 3 of drive motor 31.Internal configurations at linking department 21c has the 21e of rotation axis seal mechanism such as the gear mechanism 21d such as bearing and gland packing element.The driving force of drive motor 31 is passed to the pulley 34 of rotating cylinder 2 sides by the ring rotation band 33 that for example is erected at pulley 32.But, do not limit the transfer mode of driving force.In the present embodiment, by rotating cylinder 2, linking department 21c and drive motor 31, form the convolver structure, but be not limited to these structures.
Transmit the worm conveyor 4 of solid at the oriented solid exhaust port 22 of the internal configurations of rotating cylinder 2.Worm conveyor 4 is rotated with respect to the rotating speed of rotating cylinder 2 with having differential, by forming spiral helicine helical blade 41, to solid exhaust port 22, transmits solid.Therefore, link rotating cylinder 2 and worm conveyor 4 on the gear-box 5 as the differential generation device, when making rotating cylinder 2 rotation by drive motor 31, by gear-box 5, rotating speed changes, and worm conveyor 5 is rotated with respect to the rotating speed of rotating cylinder 2 with having differential.On the other hand, in rotating cylinder 2, by supply nozzle 23, supply with continuously processed liquid, isolate thus the parting liquid of solid and discharge (so-called overflow) from exhaust port 21a.The parting liquid of discharging from rotating cylinder 2 be fed into the inner peripheral surface that is formed on housing 3 the eaves shape be subject to liquid section 35, further by the discharge nozzle 36 be communicated with by liquid section 35, be discharged to outside device.
The lower end side opening of rotating cylinder 2 and worm conveyor 4, in the mode do not contacted with rotating cylinder 2 and the worm conveyor 4 of rotation, the front end 23a of supply nozzle 23 is inserted into opening portion.And, when the cavity (buffer) of the inside to being formed on worm conveyor 4 while supplying with processed liquid, the liquid spraying hole 42 of the main part by being formed on worm conveyor 4, processed liquid is fed in rotating cylinder 2 by the effect of centrifugal force.In addition, the front end 23a of supply nozzle 23 forms with double pipe, and the pipe in the outside is communicated with cleaning solution supplying nozzle 24.Cleaning solution can be supplied in rotating cylinder 2 for example to clean the solid be separated.But, might not need cleaning solution.
As mentioned above, worm conveyor 4 is rotated with respect to the rotating speed of rotating cylinder 2 with having relative differential.Should " being rotated " not only comprise with thering is relative differential and the situation that the speed low with the rotating speed than rotating cylinder 2 is rotated also comprise the situation that the speed high with the rotating speed than rotating cylinder 2 is rotated.As the method that forms this differential, the gear design gear case 5 or configure standby drive motor and worm conveyor 4 is applied to the method for braking torque recently of the differential of the expectation of forming is arranged.Fig. 1 means not use standby drive motor and only with the gear ratio of gear-box 5, forms the depressor 1 of the type of differential.Disclosed in gear-box 5 such as patent documentation 1 grade is known like that, therefore omits detailed explanation.
The sealing component of present embodiment then, is described with reference to Fig. 2-Fig. 5.Fig. 2 is the enlarged view of the part (A in Fig. 1) of configuration sealing component.Fig. 3 is the stereogram of sealing component, and Fig. 4 is sectional view.In addition, Fig. 5 means the schematic diagram of the situation that clamps sealing component.
As shown in Figure 2, sealing component 6 is configured to the gap 100 between seal casinghousing 3 and linking department 21c.This gap 100 is about 10mm left and right for example.In more detail, configure sealing component 6 in the mode of stopping up the gap 100 between housing 3 and linking department 21c, with the whole zone (clamped section) of the inner periphery side of the clamping unit fixing seal member 6 of linking department 21c side, with the clamping unit of housing 3 sides fixedly the whole zone of peripheral edge side (clamped section).In Fig. 2, as an example of clamping unit, show with member (such as metal annular component) 60, the 61 clamping sealing components 6 with intensity and give by the fastening units such as bolt, screw 62,63 structure that fastening pressure clamps sealing component 6.As an example, the tightening torque of to 6 bolts, giving respectively 8.6Nm, as fastening pressure, still can suitably change this fastening pressure according to the material of sealing component 6, the operating condition of device.
Then, describe the shape etc. of sealing component 6 in detail.As shown in Figure 3, sealing component 6 forms circular ring-type.The size of sealing component 6 can suitably be set according to the size of the device of installing.As an example, can be made as the about 290mm of internal diameter, the about 350mm of external diameter, the about 6mm of thickness.And shape is not limited to circle, can be made as the various shapes such as rectangular-shaped, oval.That is, can suitably determine according to the shape of the opening portion of housing 3 and/or linking department 21c the shape of sealing component 6.
In addition, the section shape (the B-B section of Fig. 3) of sealing component 6 is described, as shown in Figure 4, the part 64 that bends to upward peak shape is formed on central authorities, at the two ends (that is, this two side of inner periphery side and peripheral edge side) of the middle body 64 of this peak shape, be formed with by the zone (clamped section) 65,66 of the clamping unit of housing 3 and linking department 21 clamping.In sealing component 6, the middle body 64 of peak shape is configured in the gap between housing 3 and linking department 21c.Thereby, when making rotating cylinder 2 rotation, even owing to rocking etc. and linking department 21c causes eccentric motion, the distortion of part 64 that also can be by this peak shape absorbs this bias amount of movement.In addition, as an example, the R (radius) for peak shape, can be set as 6mm by outer circumferential side, and inner circumferential side is set as to 2mm.
Zone (clamped section) 65,66 at the two ends of sealing component 6, devices spaced apart and be formed with protuberance 65a, 65b, 66a, the 66b at two peaks diametrically.Preferably, each protuberance 65a, 65b, 66a, 66b form ring-type (with reference to Fig. 3) on the complete cycle of sealing component 6.At this, the sealing component 6 that comprises incompressible elastic material produces repulsion proportional to area of contact for compressive force.Thereby, in the situation that clamped 66,67 be smooth or general planar, by fastening the produced compressive force of fixed unit, disperseed, sometimes in order to obtain required face, press and need high tightening torque.On the other hand, in the situation that protuberance is made as to a peak, than smooth, little with the area of contact of clamping unit, produce high repulsion by the compressive force with little and bring into play sealing characteristics.On the other hand, an in the situation that peak, only the line of the protuberance by a peak contacts the inside of housing 3 (inclosure side) and outside is separated, and therefore is difficult to follow in vibration the position skew of the mounting point of transmitting, producing during anxious decompression, can't obtain stable sealing characteristics.And, when being made as two peaks that formed by protuberance 65a and 65b, 66a and 66b, area of contact is little, produces high repulsion, can access high sealing characteristics thus.In addition, in the situation that two peaks work as medial compartment in peak and peak-to-peak space (part of paddy), even produce the position skew of mounting point, also can maintain sealing state.That is,, if be made as two peaks, can stably keep sealing state.And sealing component 6 can be brought into play high sealing characteristics with little compressive force, therefore can set lowly by tightening torque.And, can realize the path (that is, setting littlely by clamped 65,66 width) of sealing component 6.In addition, about protuberance 65a, 65b, 66a, 66b, when the fabricating cost of considering sealing component 6 etc., preferably be made as two peaks, but also can be made as three more than peak.
Base cloth (being top layer) 69 these three-deckers that sealing component 6 is the bottom 67 formed by fluorine resin, the mesosphere 68 formed by the rubber series resin, formed by the nylon based material.Forming this member of three layers 67,68,69 is not that independently member is overlapping simply by difference, preferably is made as in the working process of sealing component 6 and will forms by methods such as binder, weldings the one thing that this member of three layers 67,68,69 fixedly forms.But, do not limit fixing means.
Fluorine resin is such as using PTFE etc.Bottom 67 or the face contacted with the internal atmosphere of housing 3, therefore preferably the selected internal atmosphere (that is, the handled thing of device) for housing 3 has corrosion proof material.In addition, the rubber series resin in mesosphere 68 for example can use fluorine-containing rubber (preferred FKM, for example
), nitrile butadiene rubber (NBR) etc.In addition, form the nylon based material of base cloth (cloth shape member) 69 such as using nylon 6, polypropylene etc.
Can suitably set the thickness of each layer 67,68,69.As an example, the bottom 67 that can be formed by fluorine resin is made as 0.8mm, and the mesosphere 68 that will be formed by the rubber series resin is made as 3mm, and the base cloth that will be formed by the nylon based material (being top layer) 69 is made as 0.3mm.
On the other hand, as shown in Figure 5, clamped 65 of the clamping of clamping unit, 66 opposed faces 60a, 61a form tabular surface, preferably have outstanding protuberance 60b, 61b, with the part of the end of protuberance 65b, the 66b of the inboard with sealing component 6, engage.Protuberance 60b, the 61b of this clamping unit also similarly is preferably along being formed on complete cycle in the interior week of housing 3 and the periphery of linking department with protuberance 65b, the 66b of sealing component 6.
The sealing component 6 formed as mentioned above as schematically shown in Figure 5, by clamped 65,66 of metal construction 60, the 61 clamping two ends as clamping unit, the further tightening torque cramping with regulation by the fastening units such as bolt ( reference character 62,63 of Fig. 2), clamped 65 thus, protuberance 65a, 65b, 66a, the 66b at two peaks of 66 deform (flattening) and show the sealing characteristics of withstanding goal pressure.Like this, in the sealing component 6 of present embodiment, protuberance 65a, the 65b, 66a, the 66b that are set as two peaks of the height suitable with the flattening amount contact and are out of shape with tabular surface 60a, the 61a of clamping unit, and therefore correspondingly reduction face is pressed.The situation of the schematically illustrated distortion of Fig. 5, might not be defined as the deformation state as schemed.But, if peak and valley flatten fully, the space of working as medial compartment disappears, can't tackle the position skew.And, with the shape of sealing component 6 accordingly, make the shape of clamping unit have outstanding protuberance 60b, 61b, engage with the part of the end of protuberance 65b, the 66b of the inboard with sealing component 6, the sealing component 6 that can clamp reliably thus path is guaranteed sealing characteristics.
As above, depressor 1 according to above-mentioned mode of execution, by adopting new sealing component 6, can reduce the total area of contact with clamping unit, guarantee that with little fastening pressure required face pressure can realize firm clamping, sealing member 6 is the bottoms 67 that formed by fluorine resin, the mesosphere 68 formed by the rubber series resin, the three-decker of the base cloth formed by the nylon based material (being top layer) 69, and its section shape has the part that forms peak shape 64 of central authorities and is formed with the protuberance 65a at two peaks, 65b, 66a, clamped 65 of the two ends of 66b, 66.And, be positioned at peak and peak-to-peak space (part of paddy) and work as medial compartment, can tackle the position skew of mounting point.Its result, according to the sealing component 6 of present embodiment, can guarantee and maintain the sealing state of linking department 21c and housing 3.The inventor confirms to realize high-pressure service condition (running pressure: the long-term running 0.6MPa) (more than 1 year).
And, according to above-mentioned mode of execution, even cause rotating cylinder 2 to carry out eccentric motion owing to being rotated rock (vibration) that when action produce at rotating cylinder 2, particularly the part by central peak shape can absorb eccentric mobile, and clamped is firmly clamped, therefore also can suppress sealing characteristics and reduce.In the situation that the structure as vertical settling device 1, rotating cylinder 2 suspensions supported easily cause eccentric motion, so this effect is effective especially.
And, according to above-mentioned mode of execution, by base cloth (being top layer) 69 these the three layers of sealing components become one 6 that adopt the bottom 67 formed by fluorine resin, the mesosphere 68 formed by the rubber series resin, formed by the nylon based material, can improve sealing characteristics, and easily be installed to device.In addition, the sealing component 6 of said structure has advantages of that kind by changing base cloth 69 can adjust the intensity of sealing component 6 itself.
And, according to above-mentioned mode of execution, reduce tightening torque even compared with the past, also can guarantee sealing characteristics, therefore cause that loosening etc. the situation such as bad, bolt is installed is few, easily carry out the operation of installing to device.And, can realize the path of sealing component 6, so more easily be installed to device.
[embodiment]
Then, the embodiment who carries out in order to confirm effect of the present invention is described.
As shown in Figure 6, the inventor except the sealing component 6 (a) of confirming above-mentioned mode of execution, only also confirmed, at upper surface, two peaks (b) to be arranged, a peak (c) is arranged up and down, only at lower surface, two peaks (d) are arranged, without the sealing characteristics of the sealing component of protuberance (e).Its result is shown in Fig. 6 in the lump.
According to the reason of having narrated, the sealing characteristics based on area of contact of sealing component (a) is good, and (sealing characteristics: zero), and (stability: zero) does not occur in the leakage that the position skew that causes such as vibration causes yet.On the other hand, in the situation that a peak (c) is arranged up and down, sealing characteristics good (zero), but confirm the leakage that the position skew causes (stability: *).In addition, without the smooth sealing component (e) of protuberance and certain in upper surface or lower surface, simultaneously for the area of contact of smooth sealing component (b), (d) causes greatly compressive force, disperse, by the sealing component with (a), identical tightening torque can't guarantee that required face presses (sealing characteristics: *).
Investigate the above results, following supposition.
That is, rubber also has viscoelasticity, therefore depress because stress relaxation causes plastic deformation adding, under distortion because creep causes plastic deformation.If the generation plastic deformation, the required face pressure drop of the sealing of contacting part is low, so plastic deformation is advisable less.Therefore, expect that initial face pressure is not easy the material, the shape that reduce for a long time.
Above-mentioned sealing component (a) has the protuberance at two peaks, by compressing its summit, to apply partly structure whole fastening pressure of reduction on the basis that maintains the sealing surface pressure that sealing surface is pressed, the part to paddy by the stress transfer of distortion, make it possible to reduction and be unfavorable for long-term durable plastic deformation in the lump.On the other hand, if a peak does not have paddy section, so fastening pressure also increases, and plastic deformation also becomes greatly, and durability is also undesirable.Thereby, although there is the sealing component (b) ~ (d) of protuberance to there is respectively effect, do not reach sealing component (a) yet.
Above, describe the present invention in detail in conjunction with embodiment, do not breaking away from according to the spirit and scope of the present invention of the record regulation of claims and can carry out about the various displacements of form, details, distortion, change etc., this is obvious for having those skilled in the art.Thereby scope of the present invention is not limited to above-mentioned mode of execution and accompanying drawing, record that should be based on claims and the scope impartial with it are determined.
