With reference to the accompanying drawings embodiments of the present invention are described.Fig. 1 is the profile of " rotary compression filter " of the present invention.As shown in the figure, this rotary compression filter 3 comprises: rotating shaft 32; Inner ring bushing 33; Outer ring lining 34; The permeable sieve 35,35 of two rings shape; Partition wall 36; Shell 37 and not shown drive unit etc.
Rotating shaft 32 remains the approximate horizontal state, simultaneously, by supplying with driving force by drive unit, rotates with low speed (about 0.2～3 rev/min) on the direction of arrow B shown in Figure 1.In addition, inner ring bushing 33 is fixed on around the rotating shaft 32, along with rotating shaft 32 is rotated.
Outer ring lining 34 is configured in the outside of inner ring bushing 33, simultaneously, keeps by shell 37 (with reference to Fig. 2) is fixing.In addition, outer ring lining 34 is configured to inner peripheral surface 34c and keeps certain intervals ground opposed with the outer peripheral face 33a of inner ring bushing 33 always.
Two sieves 35,35 in order to ensure water penetration, have a plurality of apertures about diameter 0.38mm, as described later, and as the filter that from handle stoste, removes moisture.
These sieves 35,35 are separately fixed on the two sides of inner ring bushing 33, when rotating shaft 32 and inner ring bushing 33 rotations, and therewith rotation.In addition, sieve 35,35 is according to position and the dimensional configurations of outer peripheral edges portion near the two sides of outer ring lining 34.
Partition wall 36, remain on approximate horizontal and with the direction of the direction of principal axis quadrature of rotating shaft 32 on.In addition, the medial end 36a of partition wall 36, consistent with the curvature of the outer peripheral face 33a of inner ring bushing 33, form and its face sliding-contact.
The outboard end 36b of partition wall 36 (with the end of medial end 36a opposition side) between the base end part 34a and terminal part 34b of outer ring lining 34, remains on the position of the predetermined distance of being separated by respectively.So, the space of guaranteeing between the base end part 34a of outboard end 36b and outer ring lining 34 as stoste supply port 38, is used to supply with the processing stoste of gatherer inside, the space of guaranteeing between the terminal part 34b of outboard end 36b and outer ring lining 34 is as filtered solid outlet 39.
In addition, this rotary compression filter 3 is the structures that sealed by shell 37 except stoste supply port 38, filtered solid outlet 39 and liquid outlet 42.In addition, this rotary compression filter 3 forms filter chamber 41 (be the space that forms, be from stoste supply port 38 until the space of filtered solid outlet 39) between inner ring bushing 33 and partition wall 36 and outer ring lining 34 in inside.As shown in Figure 2, the section of filter chamber 41 is a rectangular shape, and in addition, as shown in Figure 1, the part (rectilinear form part) of being extended by the part (annulus) of (C word shape) extension circlewise and the shape that is in line constitutes.
In addition, a plurality of scraper plates 40 are installed on the outer ring of this rotary compression filter 3 lining 34.These scraper plates 40, it is the scraper plate of slit blow formula, can will and be trapped in particulate piece in the aperture of sieve 35 etc. attached to the particulate piece in the processing stoste on the medial surface of the sieve 35 of prescribed direction rotation in the inceptive filtering stage and remove preferably, and can avoid mesh by sieve 35 to stop up preferably and the liquid measure of taking off that causes reduces (disposal ability reduction).
More specifically, these scraper plates 40 are installed in the following way, that is, with its leading section point to inner ring bushing 33 towards, base end part is fixed on the side of outer ring lining 34, its edge contacts with acute angle with respect to the medial surface of sieve 35.In addition, scraper plate 40 is installed each 4 (both sides add up to 8) respectively on two sides of outer ring lining 34, in (with 45 ° of intervals) configuration roughly equably in 180 ° the scope (inceptive filtering district) of stoste supply port 38.
Fig. 3 is the enlarged drawing of scraper plate 40, and Fig. 4 is the profile along the CC line of scraper plate shown in Figure 3 40.From these accompanying drawings as can be known, scraper plate 40, its leading section 40a side one side, width is narrower than base end part 40b side, is " shape that the front is thin ", forms the hollow stream 2 that extends in a longitudinal direction in inside.
In addition, on a face of scraper plate 40, form a plurality of slits 4 along the longitudinal.These slits 4, any one all is configured in the inside (near the position at center) of edge front end 40c, respectively with hollow stream 2 UNICOMs.Therefore, by cleaning fluid is supplied to the inside (hollow stream 2) of scraper plate 40 from the peristome 5 of base end part side, as shown in Figure 5, cleaning fluid can be sprayed towards the medial surface of sieve 35 with high pressure (with than the high pressure of entrance side hydraulic pressure of handling stoste) from each slit 4.More specifically, to be generally 10～50KPa different with the entrance side hydraulic pressure of handling stoste, and cleaning fluid can be with the pressure injection than its 0.4 higher～1MPa herein.In other words, the slit 4 of scraper plate 40 is as the jet of cleaning fluid.
Like this, when cleaning fluid under high pressure from slit 4 when the medial surface of sieve 35 sprays, can extrude and can clean to opposition side (the lateral surface side of sieve 35) by the particulate piece that the aperture that be trapped in sieve 35 is interior, can eliminate the mesh blocked state of sieve 35 aperture inside.In addition, slit 4 as previously mentioned, because any one all is configured in the inboard of edge front end 40c, therefore as shown in Figure 5, at sieve 35 during towards the rotation of the direction of arrow E, in stage after the front end 40c by the edge of scraper plate 40 will scrape attached to the solid content layer D on the medial surface of sieve 35, can directly cleaning fluid be ejected in the aperture of sieve 35, the mesh that can eliminate sieve 35 very effectively stops up.
The cleaning fluid that herein uses is had no particular limits, for example, both can make water and warm water etc., also can use surfactant etc.When using warm water and surfactant etc.,, also can be removed preferably even grease class etc. are adhered in the aperture that is trapped in sieve 35.
In addition, also can inject high pressure air (or other gases) and the steam of high temperature replace the cleaning fluid of high pressure.At this moment, can avoid cleaning fluid be blended into from handle the stoste separated filtrate situation or by the situation of cleaning solution dilution filtrate.In addition, also can be the structure of spraying warm water and high-temperature steam simultaneously.
In addition, scraper plate 40 as shown in Figure 4, except integral body is one of the forming, can use also that to be in inboard mode with groove bonding and form the parts etc. of hollow stream and slit in inside with forming fluted two sheet materials on the surface.
In addition, the shape of jet is not limited to slit, also can dispose the jet of a plurality of round-shaped, elliptical shapes or rectangular shape side by side.
In addition, jet preferably be configured to can be on the almost whole zone of the radial direction of sieve 35 jet cleaning liquid etc., but in a scraper plate 40, jet might not be configured in play gamut till the base end part 40b from leading section 40a among, for example, among a plurality of scraper plates 40 of configuration, can be in the 1st scraper plate 40 near stoste supply port 38, only form jet in base end part 40b side, in the 2nd scraper plate 40 that is adjacent, only form jet, in the 3rd scraper plate 40 at mid portion, only form jet, utilize these a plurality of scraper plates 40 to cover the whole zone of sieve 35 in leading section 40a side.When adopting this spline structure, because the aperture area of the jet of a scraper plate 40 can reduce, so as shown in Figure 3, and compare at the whole scraper plate 40 that forms jet on vertically almost, can realize bigger expulsion pressure with littler supply pressure.
Rotary compression filter of the present invention, because can be from the medial surface gas jet or the liquid of scraper plate towards sieve, therefore not only can peel off except that attachment removal and be formed on solid content layer on the medial surface of sieve, and can get rid of the interior particulate piece of aperture that is trapped in sieve, can eliminate the state of the mesh obstruction of sieve preferably.
In addition, when but the scraper plate with gas jet etc. is configured in the scope of a part in whole inceptive filtering district or inceptive filtering district, because can prevent the mesh of sieve in the inceptive filtering operation stops up, so can improve filter efficiency, even and under the situation of long-time running, also can keep the stable liquid level of taking off.
