    METHOD FOR DEGRADING AND SEPARATOR
    AEA OF THE INVENTION
    The present invention relates to a process for separating and separating liquid and dry matter from a slurry, the slurry may be of agricultural, industrial, municipal or aqueous origin, the separator having one or more inlet means for separable slurry and one or more inlet ports a discharge member for the separated solids, and the separator having one or more screen portions having a transfer screw inside the screen portion for moving the slurry in a rotary motion of the transfer screw to the discharge end of the separator having one or more sealers.
    BACKGROUND OF THE INVENTION
    A separator is also called a separator. The separator separates the liquid and solids, i.e. solids, from the sludge. Such sludge can be of agricultural, industrial, municipal or aquatic origin. >
    Several devices of different suppliers for the so-called sludge separation, i.e. liquid and dry material separation, are known in the market. Such devices also have different operating principles. Thus, on the other hand, roller press separators are used in which slurry is transported at an inclined plane, squeezing the slurry liquid through conveyor rollers. In addition, separators operating by the spinning method are known, they are called centrifuge separators.
    On the other hand, press separators are known in which fluid is squeezed from a slurry, mainly by means of a screw conveyor and, for example, a perforated cylinder. The roll press provides a relatively moist and cold dry substance, which is relatively slow to compost. In turn, press separators produce warm, rapidly compostable dry matter, according to industry publications. By separating the sludge, the load on the environment from the sludge can be significantly reduced, since in this way the bulk of the nitrogen accumulated in the sludge can be removed, with phosphorus remaining mainly in the dry matter.
    One basic construction of a press separator is disclosed, for example, in US Patent No. 63270, for example, U.S. Patent No. 4,003,304. This publication discloses an apparatus having a screw conveyor surrounded by a cylindrical perforated screening tube for pressing slurry into the screening tube. The slurry transported by the screw separates the liquid and the dry solids on the one hand.
    The use of a press separator in an agricultural environment is disclosed, for example, in DE 4343739. This publication describes how to pump slurry from a sludge basin to a press separator for treatment. The separated liquid is recovered for reuse and the solids can be diverted for example for incineration.
    However, there are significant drawbacks to prior art devices. A particular problem is the slowness of separation due to the current design and operation of these devices. The equipment is low-power and is mainly intended for continuous use, thus avoiding the accumulation of large amounts of sludge in temporary storage facilities. Due to the difficulty of separating sludge from winter to freezing temperatures, for example in the latitudes of the Nordic countries, most of the separation must be carried out during the warm season. This means that large amounts of sludge may have accumulated during the winter, for example, on the farm for separation. With current equipment, the separation of these large sludges amounts to unreasonably long-term work, which binds both machine and labor capacity. In addition, the current equipment is mainly stationary in implementation, which means that solid structures must be manufactured in the vicinity of the sludge collecting unit. Preferably, these structures should be shielded from the stresses of the equipment due to varying weather and temperatures.
    In addition to the above-mentioned separators, the separator disclosed in Utility Model Publication FI8635 and the drum screen used therein are also known. The separator disclosed in the publication is efficient and also easily portable. The disadvantage of the separator disclosed in FI 8635 is that the separator is always the same size, although the separator can be varied by the number of drum screens, the drum screens are housed in a single body of large dimensions. A further disadvantage is that modifying the number of drum screens is a retarder, especially when drum screens are added to the separator used, whereby the first cleaning is laborious and time consuming. When moving, the separator requires a large space and a heavy lifting machine due to its heavy weight.
    The disadvantage of all of the above separators is that too much liquid is still present in the solids after separation. The dry matter contains a cavity with liquid in it, which results in a not very good separation result. At present, there is no solution for cavity removal. The dry matter content is influenced by the back pressure of the exiting dry matter fraction and the dry matter by the length of the plug.
    PURPOSE OF THE INVENTION
    The object of the invention is to increase the dry matter content of the separation.
    The foregoing disadvantages can be overcome and the above-mentioned objects are achieved by the method of the invention for resilient work, characterized by what is defined in the characterizing part of claim 1. Preferred embodiments of the invention are the subject of dependent claims 2 to 3. The flexible mechanism of the implement is characterized by what is defined in the characterizing part of claim 4. Preferred embodiments of the implement flexible mechanism are disclosed in the dependent claims 5 to 10.
    DESCRIPTION OF THE INVENTION
    The main advantage of the invention is that the dry content of the dry matter resulting from the separation increases. In accordance with the invented method, at the discharge end of the separator, the solid is compacted by reducing the discharge end cross-section by a cone shape of the discharge end, or preferably by a separately replaceable dry concentrator disposed at the discharge end. By free cross-sectional area is meant the area from which the solids must pass in order to escape the discharge end from the discharge opening / discharge member by sealing a known dry sealer. It is clear that the invented method and the separator will result in high cost savings in the separation by improving the separation result.
