    • 专利摘要:
    An annular strainer for paper stock comprises a stack of identical strainer basket rings 1 spaced apart axially by separate members 2 to define strainer slots between the rings. The rings are of uniform, generally flat cross-section, with a slight taper towards the downstream side, while members 2 are similarly tapered in the opposite direction. Rings and/or members 2 have through holes 6 accommodating clamping screws which connect the two rings at the ends of the stack. The strainer is simple to produce, has a low flow resistance for the fibrous stock to be strained, and there is little tendency for the strainer slots to become blocked. <IMAGE>

    The invention relates to equipment for preparing paper pulp before it is cast on the grid of a paper machine and can be used in the pulp and paper industry. A slotted, cylindrical, knotted sieve for cleaning Hoi mass paper is known that contains a screened sheath consisting of a set of coaxially mounted rings and is located between the support surfaces of the rings spaced apart from one another by the dividing plates to form screening slots with a height, equal plates , the profile is transverse. the cross section of which relative to the axial section of the sieve corresponds to the cross section of the rings 1 In the specified sieve, the gaps between the rings have a rectangular cross section, which leads to their clogging with paper pulp, and, as a consequence, to insufficient reliability of the sieve and cleaning of the paper pulp. The purpose of the invention is to increase the reliability of the sieve and improve the cleaning of paper pulp. The goal is achieved by the fact that the cross-sectional profile of the rings of a spline cylindrical sieve of a knotter for cleaning paper pulp containing a screening sheath consisting of a set of coaxially mounted rings and located between the support surfaces of the rings. separating separator plates from one another for the formation of projectivating slits with a height equal to the height of the plates, whose cross sectional profile relative to the axial section of the sieve corresponds to the cross sectional profile of the rings, is tapered in the direction of movement of the cleaned pulp in the opposite direction . In this case, the angle of the S5 ring of rings and separator plates can be 2-10 °. The separator plates can be displaced relative to the rings in the radial direction in the direction opposite to the direction of movement of the cleaned pulp. In addition, the sieve may have a device for clamping the rings of the shell, consisting of two additional plates installed along the ends of the shell and bolts running parallel to the axis of the shell for tightening additional plates. Figure 1 shows the sieve, a general view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 2; figure 4 - sieve 5 is the same, with offset separation plates. The cylindrical screen of the host contains a shell consisting of a set of rings 1 and separating plates 2 installed between them. The shell has a device for compressing a package of rings and separating plates, consisting of two additional plates installed at the ends of the shell; plates 3, bolted 4. These bolts can pass through the package of butts and separation plates, and on the sides of the shell (Fig; 4). Due to the separation plates 2 between the rings 1, slots 5 are formed, expanding in the direction of movement of the cleaned pulp. Plates for separation of the gauge can be minimized in the radial direction in the direction opposite to the movement of the mass being cleaned, which contributes to a better cleaning of the gaps between the rings of the shell. The most preferred taper angles of the rings and separator plates are. The device works in the following way. The paper pulp to be cleaned can be fed as internal,. and on the outer cylindrical surface of the shell. Passing through the slits of the screen, the mass is cleaned of unwanted inclusions. Due to the expansion of the screen gaps in the direction of movement of the paper pulp, the paper pulp fibers do not get stuck in them, which increases the reliability of the screen. The displacement of the separation plates in the direction opposite to the movement of the mass to be cleaned in the radial direction makes it possible to obtain gaps on the inlet side less than the thickness of the separation plates. Thus, the cylindrical sieve of the proposed. Construction is more reliable in operation than the known and better cleans the pulp.
