Description
Technical field
The utility model relates to a kind of screening plant for wet screening fibrous substance suspension, comprise and there is the sieve of a plurality of sieve apertures and be arranged on the rotor on sieve feed side, wherein, the fan-shaped section that sieve is arranged by a plurality of surrounding rotors forms, these fan-shaped section on the exit side of sieve along the side of direction of rotation and in face of the side upper support of direction of rotation between two adjacent fan-shaped section radially on the supporting slat separately of trend, wherein, between two adjacent fan-shaped section and supporting slat separately, form one towards rotor openings and the passing away of trend radially.
background technology
This screening plant advantageously uses in the pulper of slurry Preparation equipment of the fibrous substance suspension in being used to form pulp and paper industry.At this, the fibrous material of the dirt of fiber foreign matter and not yet size degradation is because its size is retained and is deposited on sieve.The fiber of size degradation can pass through sieve aperture with a part of water jointly at this.The characteristic of this sieve is substantially from size, shape and the quantity of the inside sieve aperture of living in.
For preventing sieve pore blockade, on feed side, adjacent sieve is provided for producing the pressure of hydraulic pressure and the rotor of suction impulse force in this sieve the place ahead.
In addition,, when the passing away skimming between fan-shaped section, thick dirt is reamed by rotor and radially discharges.This point suppresses the obstruction in very little gap mostly between rotor and sieve.
Because especially fan-shaped section is born high load capacity, so these fan-shaped section must correspondingly more expensively be changed more continually.
summary of the invention
Therefore.Technical problem to be solved in the utility model is, in the situation that guaranteeing fan-shaped section function as far as possible on a large scale, extends its service life.
This technical problem is achieved thus according to the utility model, in fan-shaped section, on the side of direction of rotation, connect the radially wear strip of trend, this wear strip is removably fixed in fan-shaped section on supporting slat and/or separately and limits the border of a side of passing away.Recognize in this case, fan-shaped section is born very large wearing and tearing in face of the border with limiting a side of passing away of direction of rotation.High load capacity by passing away be attached to epitrochanterian interfering material acting in conjunction and shearing force related to this and obtain.
For extending the service life of fan-shaped section, the region of its quick-wearing forms by being configured to corresponding anti abrasive wear strip now.
The replacing of wear strip is obviously more simple and cheap.
While skimming over passing away for improving, interfering material and rotor is separated, and wear strip has the radially sheared edge of trend in the region towards rotor and passing away.Tool is advantageous, and this sheared edge forms right angle or acute angle.
In addition tool is advantageous, and wear strip has quadrangular cross section.If opposed faces forms identical or minute surface is contrary, especially after sheared edge excessive wear, can pull down wear strip and re-use under the second state of preferably upset so.The possibility that this point provides is to be doubled the service life of wear strip.
This solution is particularly suitable, and sieve aperture is designed to perforation, and its diameter, between 4 to 10mm, is preferably between 0.5 to 2mm in the gap width between 6 to 8mm and/or between rotor and sieve, preferably between 0.5 to 1.5mm.This point is intended to avoid stopping up the danger increasing.
For stable structure screening plant as far as possible, on the supporting slat that the side of fan-shaped section inner radial and outside trend moves towards in a circumferential direction at its exit side upper support.
Accompanying drawing explanation
For manufacturing the pulper of the required manufacture fibrous substance suspension of paper web, be that example is elaborated to the utility model below.Wherein:
Fig. 1 is the top view of sieve feed side 3;
Fig. 2 is by having the part cross section of the sieve of rotor 2; And
Fig. 3 is the part cross section by two adjacent fan-shaped section 4.
The specific embodiment
Annular sieve is comprised of fan-shaped section 4 as seen from Fig. 1.In this regard, fan-shaped section 4 structure is identical and have a sieve aperture 1 of the well format between a plurality of diameters 6 to 8mm.
Fan-shaped section 4 is according to Fig. 1 and 2 around the rotating shaft that is arranged on the rotor 2 on sieve feed side 3, and this rotor guarantees the free space of sieve.
At this, the edge of fan-shaped section 4 with its exit side 6 be bearing in radially with circumferencial direction on the supporting slat 7 that moves towards, the edge of fan-shaped section is also connected with supporting slat bolt.Distance between rotor 2 and fan-shaped section is between 0.5 to 1.5mm.For preventing that this gap from stopping up, between fan-shaped section 4, have trend radially and towards the passing away 8 of rotor 2 openings.If rotor 2 skims over this passing away 8, interfering material or the pars fibrosa that may be attached to so on rotor 2 stretch in passing away 8.When these interfering materials or fiber are encountered the wall of the passing away 8 in restricting rotation direction, interfering material or fiber are cut from rotor 2.
This point causes the high wear of this wall.Therefore this wall of passing away 8 is formed by the wear strip 9 radially moving towards in the utility model, and this wear strip 9 is connected with the side of fan-shaped section 4 in face of direction of rotation 5.In this regard, wear strip 9 is also removably fixed on corresponding supporting slat 7 by high-abrasive material manufacture.
For auxiliary interfering material or fiber cut, wear strip 9 in the region towards rotor 2 and passing away 8, have as shown in Figure 3 trend radially and at the sheared edge 10 at this right angle.
Utilize the benefit of wear strip 9 to be on a large scale, this wear strip has tetragonal cross section, and wherein, opposed face is designed to identical.If sheared edge 10 wearing and tearing, can pull down so wear strip 9 and reinstall this wear strip 9, to use as new sheared edge 10 now with the opposed limit of sheared edge 10 of wearing and tearing.In this manner, can be doubled the service life of wear strip 9.
