    The invention relates to a machine. Press. drying and filtering sludge, fibrous or cellulose. mx suspensions.
    The purpose of the invention is to create a pressing and dewatering or filtering machine, which provides constant pressure for a long period of time, and which has been compressed. so that there is a possibility of perceiving both the differences in the thickness of the layer of the cake and the compression of the cake without lowering the pressure and pressing.
    Figure 1 shows a schematic representation of a dewatering machine, profile; figure 2 - pressurized cushion of the machine, the section; on fig.Z - sequential arrangement of several pressure pads; figure 4 - the location of several pressure pads, one to another.
    The dewatering machine of a compact design (Fig. 1) has lower 1 and upper 2 infinite filtering belts between which the dehydrated material passes. In the pressing zone both filtering belts 1 and 2 are under ;. Wed. 3 and 4, which are made from an elastic gtr of impermeable material, such as rubber or synthetic mother .uia. To create the necessary pressing condition on the pressure tapes 3 and h or further on the filter tapes 1 and 2, and thus on the cake placed between them, supports 5 i (which take full pressing acceleration and for this purpose 1 are very stable. With Both sides of the dewatering top and bottom 5 props are connected to each other to ensure the transfer of all efforts in the short section. The advantage of this is that very large pressing forces are not transmitted to the machine frame, so that the machine frame can This life is relatively light and inexpensive.
    The material to be dewatered is fed from the loading device 7 to the lower filter penta, so that a cake of almost uniform thickness is formed, which w can dehydrate between the two filter belts 1 and 2.

    3 and the top 4 pressure belts are then driven through the drive rollers 8.8, guiding rollers 9.9 tension 10.0 and equalizing rollers 11 and 1 1,
    At the beginning and at the end of the pressing section, there are respectively smaller guide rollers 12 and 12. The lower filter belt 1 is made in the form of a support grid and passes through a number of rollers, namely, approximately. 1 roller 1 1, tension roller 13, the guide roller 14. The upper filter belt 2 is made in the form of a covering net and passes through the equalizing roller I, the tension roller 13, the guide rollers 14. For ne)) effort from the supports 5 and 6 and moving strength tapes 3 and -50 SL50KIT special hydrostatic device, BbHiojrHBHHOc in the form of a pressure pad, located on the upper support 6. For this, there is a bend that is made of bending elastic, resistant to growth Research institutes of material, such as synthetic or rubber cloth, a hollow pillow 15, which with the help of square or rectangular frames 16 is attached tightly to the liquid to the upper support 6. Between the pressure band 4 and the support 6 is formed a pressure cavity 17, and inside The cushion 15 is formed mainly by a closed pressure cavity 18. A part of the working medium leaves the pressure cavity 17 through very narrow11 (from 0.005 to 0.1 mm, in particular about 0.03 mm) a gap 19 between the hollow pillow 15 and the sliding tape 4. The pressure chamber 17 is formed or provided with a working medium through the opening 20, preferably pressurized water, thereby maintaining the hydraulic pressure. The discharge chamber 18 is filled with a similar or other pressurized working medium. In spite of the overpressure in the pressure chamber 7, only a minor amount of working medium escapes, which must be constantly compensated through the feed holes 20 and 21. This allows the SPD to maintain an overpressure in the pressure cavity 17, which also acts on the pressure belt 4 and thus its pressure over the surface at
    the upper filter belt 2 is further onto the cake 22. As a result, flat pressing of the material to be pressed is ensured.
    In the case of variations in cake thickness 22, as is the case, for example, with somewhat uneven feeding, as well as as a result of compression of cake 22

    It avoids lateral pressing out of the material.
    1a of FIG. 3 is shown in terms of the jiac-position of several hollow sub-sleeves 15. The rectangular or square shape of the hollow cushions 15 with internal and external clamping frames 16, 16 and also
    The gap between the pressure Q with the supply hole 20, the adjacent tape 4 and the support 6 also changes due to the pressure of the pressure cavity I7
    elastic performance and shape of the cushion 15, as well as its pressure in the pressure cavity 18, so that in all modes of operation Zazoz 1h remains very insignificant. As a result, another major advantage of the invention is manifested, in spite of the fact that, despite the significant surface pressure applied to the surface between the fixed parts and the movable pressure belt 4, only liquid friction takes place, so that small resistances and thus n;) and the power of the dewatering machine is very small, which significantly increases the economy of the dewatering process.
    The pressure tapes 3 and 4 are preferably made impermeable to liquids and take place on their 1 and 2 sides facing the filter tapes, respectively, the grooves 23, which extend substantially transversely or obliquely with respect to the direction of rotation F of the pressure tapes 3 and 4 or filter tapes 1 and 2. With its side facing the elastic pressure cushion 15, the pressure tapes 3 and 4 are smooth. Inside the support or pressing device between the filter belts 1 and 2 or the pressure belts 3 and 4 are moving in the direction of movement F, two other sealing belts 24 and 25, the surface of the outer edge 26, 27 of which is viewed from above or below, outside the hollow cushion or hollow frame 15, and the surface of the inner edge 28, 29 inside the hollow cushion or hollow frame 15, and these sealing tapes significantly iOKe mesh tapes 1 and 2 or pressure tapes 3 and 4 and during operation limit laterally with seal located between the set dewatering, filtered, or compressible material 22

    and the feeding hole 21 of the pressure cavity 18 inside the hollow sheet. Several such hollow cushions 15 on the supports 5 and 6 can be arranged one after the other in the direction of movement F of the pressure belts 3 and 4, npvmeM in FIG. 3, three consecutively located hollow pillows 15 are shown as an example.
    Separate powering of all three pressure cavities I7 allows different pressing pressures to be set, for example, upwards in the machine direction. This has great advantages in terms of achieving the best dehydration effect and ensures further improvement of the invention as a whole.
    Another possibility of arranging several hollow pillows 15 is presented in FIG. 4. In this case, several hollow pillows 15 are located not one after the other, but one inside the other, so that a correspondingly large floor pillow completely covers less than a hollow pillow.
    The device works as follows.
    The material to be dehydrated is fed from the loading device 7 onto the lower filter belt 1, covered with tape 2 and subjected to continuous pressing for a long period of time. As a result of this process, continuous dehydration and a very high degree of dryness are achieved, so that, for example, materials that subsequently, drying must now require an insignificant energy expenditure in the dryer.
    In order to achieve the continuity of the extrusion, there are upper and lower circulating pressure tapes 3,4, which pass through the press and guide rollers. The ffly tapes are, in the illustrated embodiment, impermeable and serve
