Summary of the invention
The present invention makes under this background, its object is to provide a kind of and do not need complicated structure or large space, handled thing reliably can be prevented to the attachment of the piston rod of work cylinder device and the bad or working media of the action of piston rod can be prevented to the removing device of the centrifugal separator to be mixed into etc. of handled thing, and then a kind of work cylinder device being adapted at using in this removing device is provided, a kind of compact centrifugal separator possessing this removing device is provided in addition.
This object is realized in order to solve above-mentioned problem, removing device of the present invention is being centrifugated in the centrifugal separator of solid state component and liquid parts by the handled thing be supplied in basket, possesses the scraper plate struck off by the described solid state component be attached on the inner peripheral surface of described basket, described basket is by substrate support and rotate, the removing device of described centrifugal separator possesses: be arranged at described matrix, and along the work cylinder device that the central axis almost parallel with the rotation of described basket is retreated; Make the rotating mechanism that described work cylinder device rotates around described central axis, described work cylinder device has working cylinder and is inserted into the piston rod in this working cylinder, described piston rod can support on the matrix by described rotating mechanism rotatably, described working cylinder is retreated along described central axis, and described scraper plate is installed on described working cylinder.
Centrifugal separator of the present invention is the centrifugal separator handled thing be supplied in basket being centrifugated into solid state component and liquid parts, possesses removing device of the present invention, and described basket is by substrate support and rotate.
Therefore, at removing device of the present invention and possess in the centrifugal separator of the present invention of this removing device, possess piston rod in the work cylinder device of working cylinder and piston rod by substrate support for rotating, from by the piston rod that supports, the working cylinder covering its periphery can be retreated in basket.And the scraper plate be arranged on this working cylinder rotates together with work cylinder device, thus, scraper plate is trapped in the solid state component of the handled thing adhered on basket inner peripheral surface and is peeled off.In above-mentioned underslung centrifugal separator, above-mentioned work cylinder device relative to the structure described in patent document 1 with the upper end of state support piston rod of standing upside down.And, different from the structure described in patent document 2, retreat in basket downwards as by the working cylinder of the urceolus of piston rod supported.
Because piston rod does not expose in basket, what retreat in basket is only working cylinder, and therefore handled thing can not be attached to piston rod.And, even if handled thing is attached to the surface of the working cylinder being provided with scraper plate and solidifies, the situation causing the hermetic unit of obstacle or working cylinder impaired to the moving back and forth of work cylinder device also can not be there is.Consequently, even if this work cylinder device is hydraulic cylinder assembly, working media also can not be mixed in handled thing.And, as long as guarantee that on matrix supporting piston bar is carried out in the space of the length about the stroke of the working cylinder of roughly work cylinder device, the densification of centrifugal separator can be realized.And, do not need the bar beyond this piston rod maybe by the wiping scraping blade etc. that the handled thing adhered to removes, therefore, it is possible to form simple structure.It should be noted that, scraper plate not only can be installed on working cylinder, also can via the component installing working cylinder.
Wherein, in patent document 1,2, as recorded, in working cylinder is supported, employ the common work cylinder device that piston rod is retreated.In common work cylinder device, by the surrounding wall portion of working cylinder or end wall from outside connecting pipings respectively, thus the Liang Ge balancing gate pit being completely cut off along its central axial direction in working cylinder with the piston by piston rod by the stream of working media and formed is communicated with.Via these pipe arrangements, working media is supplied to each balancing gate pit/discharges, make piston rod retreat thus.
But, in the removing device of said structure, working cylinder is come in and gone out and is rotated in basket, therefore when being externally connected to this pipe arrangement at it, following situation may be there is: the solid state component peeled off by scraper plate and this pipe arrangement are collided and produce damage, or be attached to this pipe arrangement and cleaning work etc. after causing the Separation of Solid and Liquid of such as handled thing to terminate becomes miscellaneous because of handled thing, solid state component.And, in order to utilize outside pipe arrangement to carry out the supply/discharge of working media, this pipe arrangement must be formed as the pipe arrangement can following the advance and retreat of working cylinder, the flexibility of rotation, flexure or extension all repeatedly during each stripping, the therefore lost of life.
Therefore, in the work cylinder device of the present invention of removing device of the present invention and this removing device, form the stream of working media on the piston rod, thus, even if not as described above at the outside connecting pipings of working cylinder, also can carry out the supply/discharge of the working media to Liang Ge balancing gate pit, thus can avoid causing problem as described above.Such as, use be inserted with the common work cylinder device etc. of a piston rod along the central axis of working cylinder time, in work cylinder device, the stream of multiple working media can be formed on this root piston rod.And, can by the stream of the working media of the part in the stream of this multiple working media with to completely cut off along central axial direction in working cylinder and a side in the Liang Ge balancing gate pit formed is communicated with, and the stream of remaining working media to be communicated with the opposing party in Liang Ge balancing gate pit.Thus, make described stream across the piston of piston rod to both-side opening, be communicated with two balancing gate pits completely cut off by this piston all the time in the stroke of working cylinder.
On the other hand, when only piston rod being inserted along the central axis of working cylinder like this, working cylinder can be relatively rotatable around central axis relative to piston rod, even if utilize rotating mechanism to make work cylinder device rotate, also with suitable pressing force, the scraper plate being installed on working cylinder cannot be pressed on the solid state component of basket inner peripheral surface.Therefore, in this case, the chimeric restriction that such as can utilize key and keyway (keyway) relatively rotates and working cylinder is retreated.But, in this case, the key of working cylinder side or keyway must be arranged on its periphery, and the wearing and tearing powder that therefore slip of key produces may cause new being mixed into.
Therefore, in the work cylinder device of the present invention of removing device of the present invention and this removing device, also multiple piston rod can be inserted in working cylinder in parallel to each other, at least one piston rod in these piston rods is inserted into the position from center axis.The insertion portion to working cylinder being inserted into the piston rod of the position of this bias becomes spline part, therefore not be used in periphery and arranges the relative rotation that key as described above or keyway just can limit working cylinder.
In addition, when to be inserted in parallel to each other by multiple piston rod in working cylinder and to form the stream of working media as described above on this piston rod, also arbitrary in multiple piston rod can form two streams be communicated with respectively with above-mentioned Liang Ge balancing gate pit.But, in the work cylinder device of the present invention of removing device of the present invention and this removing device, also the piston rod of a part in this multiple piston rod can be formed and completely cut off along central axial direction in working cylinder and the stream of working media that a side in the Liang Ge balancing gate pit that formed is communicated with, the stream of the working media that formation is communicated with the opposing party in Liang Ge balancing gate pit on the piston rod at least partially in remaining piston rod.Thereby, it is possible to prevent the situation that the sectional area because of specific piston rod reduces and its rigidity is impaired.

Next, via rotating shaft 1, basket 4 is rotated by motor 3.Further, when supplying handled thing via supply pipe 7A from tank 7B when opening valve 7C in basket 4, the handled thing of supply is pressed against on the inner peripheral surface of basket 4 under the influence of centrifugal force, and its liquid parts is filtered by filter screen 5 and is separated from solid state component S.And isolated liquid parts disperses from the through hole of basket 4 main body perimembranous and is recycled in the lower case 2C of matrix 2, discharges from outlet 2E.
On the other hand, the solid state component S isolating the handled thing of liquid parts keeps the state be attached on the inner peripheral surface of basket 4 under the influence of centrifugal force.Therefore, in order to utilize removing device 10 that above-mentioned solid state component S is struck off and discharged, the rotary speed of basket 4 is first made to slow down than rotary speed during Separation of Solid and Liquid.And, by making the work cylinder device 15B of rotating mechanism 15 extend, work cylinder device 11 and scraper plate 16 are rotated together with swivelling arm 15A, as shown in the double dot dash line in Fig. 7, make the scraping blade 16B side of this scraper plate 16 close to basket 4 inner peripheral surface and be trapped in the solid state component adhered on this inner peripheral surface.Meanwhile, lid 6 is made to rise and make the inner peripheral portion opening of Circular Plate portion, the lower end 4B of basket 4.
In the part that scraper plate 16 is absorbed in, along with the rotation of basket 4, solid state component S is stripped, when basket 4 revolve turn around time, in the position in rotation O direction being equipped with scraper plate 16, solid state component is fallen by striking off on complete cycle.The solid state component fallen is discharged from the outlet 2D of lower case 2C by the inner peripheral portion of Circular Plate portion, the lower end 4B of the basket 4 of opening.
Then in the work cylinder device 11 of removing device 10, supply as the air of working media to the balancing gate pit 12A in working cylinder 12 via stream 17A, and discharge air via stream 17B from balancing gate pit 12B.Thus, make work cylinder device 11 extend gradually and working cylinder 12 is advanced, as shown in the double dot dash line of Fig. 6, make the lower ora terminalis of scraper plate 16 close to the upper surface of Circular Plate portion, the lower end 4B of basket 4.Thus, the solid state component S be attached on basket 4 inner peripheral surface is stripped and all discharges in the total length in rotation O direction.
After solid state component S is discharged, when carrying out Separation of Solid and Liquid being supplied in basket 4 by the handled thing of next batch, in work cylinder device 11, discharge air from the balancing gate pit 12A in working cylinder 12 via stream 17A contrary to the abovely, and via stream 17B to balancing gate pit 12B air supply.Thus, work cylinder device 11 shrinks, and makes working cylinder 12 again back to original position (upper edge of scraper plate 16 is close to the position of the lower surface of Circular Plate portion, the upper end 4A of basket 4).Now, even if handled thing or its solid state component S are attached to the outer peripheral face of this working cylinder 12, in the removing device 10 of said structure, the urceolus of work cylinder device 11 and working cylinder 12 also can be retreated in basket 4.Therefore, even if directly make working cylinder 12 retreat, the part that subtend working cylinder 12 loads piston rod 13 is carried out the solid state component S that gas-tight seal hermetic unit also can not be attached and is damaged.
Therefore, there is not the situation of to leak as the air of working media because sealing is partially damaged so that causing obstacle such to the action of work cylinder device 11.And, although work cylinder device 11 is air cylinder device, even if be hydraulic cylinder assembly, also can not occur go out as the oil leakage of working media and be mixed into the situation in the liquid parts of handled thing or solid-liquid separation, solid state component S.Therefore, by the action smoothly of work cylinder device 11, can reliably the solid state component S being attached to basket 4 inner peripheral surface be struck off and discharge.When especially using in food industry or pharmaceuticals industry etc., also can not there is the situation causing the qualification rate of product to decline because of being mixed into of working media.Therefore, it is possible to realize the separation of effective handled thing.
The removing device 10 of present embodiment is configured to, and piston rod 13 is upwards fixed along the central axis C direction of work cylinder device 11, and working cylinder 12 is retreated relative to this piston rod 13, thus working cylinder 12 passes in and out in basket 4.That is, piston rod 13 does not expose in basket 4, and what retreat in basket is only working cylinder 12.Therefore, compared with the removing device described in the same patent document 2 upwards arranged by piston rod, do not need other bars parallel with piston rod, and on work cylinder device 11, do not need space that piston rod is haunted.Therefore, it is possible to realize the simplification of the structure of removing device 10 and the densification of centrifugal separator.
In addition, the wiping scraping blade etc. scraped by the handled thing be attached on other bars the removing device described in this patent document 2 is not needed.Therefore, it is possible to the further simplification of implement device structure, and being mixed into of the foreign matter that can prevent shortcoming or wearing and tearing etc. because of this wiping scraping blade from causing.Removing device 10 also can be configured under the state that handled thing is attached to the outer peripheral face of working cylinder 12 as described above, working cylinder 12 be retreated.But, after also can terminating the Separation of Solid and Liquid operation of such as a succession of batch, when cleaning basket 4 or scraper plate 16, as shown in Figure 2, arrange the pedestal 2A that is formed at matrix 2 and towards working cylinder 12 the cleaning device 18 of through hole given prominence to.This cleaning device 18, towards the outer peripheral face jet cleaning water of working cylinder 12, rinses the handled thing be attached on this outer peripheral face.
In the removing device 10 of present embodiment, stream from working media to balancing gate pit 12A, the 12B in the working cylinder 12 being formed in work cylinder device 11 17A, 17B of supplying/discharge are formed in on the piston rod 13 of this working cylinder 12 insertion, are connected to form the pipe arrangement of stream without the need to the outside at working cylinder as common work cylinder device.Therefore, especially in part outstanding in basket 4, solid state component and such pipe arrangement that stripping can not occur are collided and cause the situation of damage.And, do not need the pipe arrangement of the flexibility this pipe arrangement being formed as the advance and retreat can following working cylinder, therefore, it is possible to the striking off of the solid state component that produces of the advance and retreat of carrying out stable work cylinder device 11 for a long time yet.
