The invention relates to a device for treating fibrous materials and can be used in tse :: lump paper industry.

The purpose of the invention is to increase productivity and reduce the noise produced during operation.

Figures 1-3 show a device for treating fibrous materials with different types of structures.

A device for treating fibrous materials consists of a housing 1 with connections for supplying 2 the initial suspension and removal 3 of the processed product. According to the design variant, the device may have an additional Hboi nozzle 4 for supplying the initial 11 suspensions. Inside the housing 1 there is a conical rotor 6 mounted on the drive shaft 5 and a conical stator jacket 7 surrounding it with rows of protrusions 8 and 9, respectively, and grooves between them;

stand for its face surface along the longitudinal axis of the device.

The conical casing 1P is fixed to the housing 1 by means of an annular protrusion 16. An additional stator jacket 12 is attached to the stem 17 of the mechanism 18 for axial movement.

The housing 1 is provided with an end cap 19, in which an axial movement mechanism 18 can be fixed, connected to the end wall 20 with windows 21 fixed to an additional

stator} 1st shirt 12, provided with protrusions 22 and channels between them.

The device works as follows.

In parallel processing of the fibrous material (Fig. 1), the initial suspension through the pipes 2 and 4 is fed into the housing 1, filling the annular cavity 11 through the windows 21 in the top of the wall 20, entering the cavity

at least 25 additional stator shirts 12 on the side.

the nozzle 2 for supplying the initial suspension, the protrusions 8 of the rotor 6 are inclined to the radial planes and protruding beyond its end surface along the longitudinal axis of the device. On the inner surface of the housing 1, a conical housing 10 is formed, which forms with the housing 1 an annular cavity 11 communicating with the pipe 2 for supplying the initial suspension, while the stator jacket 7 is fixed on the conical housing 10, the pipe for supplying the original suspension 2 is placed on the housing 1 radially and conical

From the cavities, the suspension is fed in parallel flows into the working gaps between the protrusions 8.9 and 13.22 of the rotating rotor 6, the main 7 and the additional 12 stator jackets. After processing through the working gaps, the processed suspension fills the annular cavity 14, from where it is discharged through pipe 3. During sequential processing (FIGS. 2 and 3), the initial suspension through pipe 2 is fed into the housing 1, filling the annular cavity 11, from which it enters the working gap lugs 8 rotating

The device can be equipped with an additional conical stator jacket 12, the rotor 6 can be made hollow with additional protrusions 13 and grooves between them on its inner surface, with an additional stator jacket 12 placed in the cavity of the rotor 6, the conical casing 10 forms with the housing 1 an additional annular cavity 14 communicating with the nozzle 3 for withdrawing the treated product. The main 7 and additional 12 stator jackets can be connected in the zone of their largest diameter by means of an annular groove 15, and the additional protrusions 13 of the rotor 6 in the zone of its largest diameter can be filled

The fibrous material enters the annular groove 15, from which it is guided into the working gap between the protrusions 13 and 22, respectively, of the rotating rotor 6 and the additional-stitched stator jacket 12. The processed product enters the cavity of the additional stator shaft 12, from which directly 2) through the windows 21 in the butt-shaped wall 20 (FIG. 3) - into the annular cavity 14, from which it is discharged through the nozzle 3.

From the cavities, the suspension is fed in parallel flows into the working gaps between the protrusions 8.9 and 13.22 of the rotating rotor 6, the main 7 and the additional 12 stator jackets. After processing through the working gaps, the processed suspension fills the annular cavity 14, from where it is discharged through the pipe 3. During sequential processing (Figures 2 and 3), the initial suspension through the pipe 2 is fed into the housing 1, filling the annular cavity 11, from which it enters the working gap lugs 8 rotating

The fibrous material enters the annular groove 15, from which it is guided into the working gap between the protrusions 13 and 22, respectively, of the rotating rotor 6 and the additional-stitched stator jacket 12. The processed product enters the cavity of the additional stator shaft 12, from which directly (FIG. 2) through the windows 21 in the butt-shaped wall 20 (FIG. 3) - into the annular cavity 14, from which it is discharged through the nozzle 3. When rotating 6, protrusions 8 protruding beyond its end surface are located at an angle to the longitudinal axis of the device , Braz filar zone, directing the suspension into the processing zone at, vzaimodeG1Stvu with adjacent protrusions 9 of the stator core 7 shirts, they carried out a preliminary processing of incoming slurry breaking co derzhapshes therein large fibrous includant. Adjacent to the opposite f end of the rotor 6, the protrusions 13, by appropriately adjusting their angle of inclination to the longitudinal axis of the device during sequential processing (Figures 2 and 3), direct the suspension to the second treatment zone between the rotor 6 and the additional stator jacket 12 , with parallel processing (FIG. 1), the protrusions 13 facilitate the selection of the treated product from the treatment zone.

Thus, the device can have two treatment zones for the fibrous material. In this case, the design capabilities are realized more rationally: with parallel processing, productivity increases significantly, with sequential processing its intensity (quality). In both cases, the specific technological parameters of the device increase. The fact that the protrusions 8 and 13 adjacent to the ends of the rotor 6 perform both processing and guiding functions, contributes to an increase in the productivity of the device. The entry zone formed by them, which preliminarily preprocess the suspension with breaking up difficult-to-open fibrous inclusions, facilitates their entry into the treatment zone and, accordingly, more efficient and complete processing of the incoming suspension. The presence of annular cavities 11 and 14, which are filled with a suspension, isolating the treatment zone of the suspension from the radiating surface of the housing 1, contributes to the reduction of the device produced during operation of the schum.
