    An apparatus is provided for the defibration and conditioning of nonflowable cellulosic material, comprising a housing having an inlet and an outlet and a flow chamber for cellulose material therebetween; two screws disposed in the chamber and extending from the inlet to the outlet, the screws having interdigitating helical blades with opposed pitches, and helical grooves therebetween receiving the helical blades of the opposite screws; the screws being arranged for interdigitating rotational movement in opposite directions, so as to defibrate and condition cellulosic material in the bite therebetween while carrying the material through the flow chamber from the inlet towards the outlet; at least a portion of the outer periphery of each helical blade being undulating in a plurality of successive recesses and projections, intermeshing short of contact with a like plurality of projections and recesses defining a land area in the groove of the opposite blade of the other screw, so that within the land areas in the bite of the screws the intermeshing projections of one groove occupy at least part of the recesses in the blade of the other screw to extend the filled-in area of the blade surface along each screw, for improved screw efficiency in defibration and conditioning of the cellulosic material, and transport of the material through the flow chamber.

    one
    This invention relates to pulp processing devices and may find application in the pulp and paper industry.
    A device for dissolving and conditioning pulp is known, comprising a housing with loading and expanding and loading connections and installed in it with the possibility of rotation, at least two parallel wiring, which engage one another and have -, in the plots of at least one of the spiral turns of the -1.18 depression
    However, the radial compression to which the pulp is subjected is not sufficient to obtain the desired quality in the finished product. An increase in the size of the depressions of the turns of the auger Tuzvolta to achieve an increase in the quality of the product obtained, however, the productivity of the device is significantly reduced .26
    The aim of the invention is to increase the productivity and quality of the product obtained.
    This goal is achieved by the fact that in a device for the dissolution and conditioning of cellulose, comprising a housing with unloading and unloading nozzles and installed in it with the possibility of rotation, at least two parallel wrenches, which engage one another with another. on the peripheral sections of at least one of the spiral turns of the depression, each auger has rods installed along its forming sections,
    provided with hollows.
    . .
    Moreover, the rods of each screw mounted on its shaft.

    [1]
    The rods can be installed with a gap relative to the shaft of each screw and secured on the helix. In addition, the rods of the screws are made of connected parts, and the spirals of the screws have holes for mounting the rods. At the same time, the rods and side surfaces of the protrusions that form depressions on the spirals of the auger have a surface with serrations. The device also has removable; elements whose surface has notches and which are mounted on rods and / or side surfaces of the projections. Moreover, the rods are mounted on the shaft of the screws and / or spiral with the possibility of removal. Fig. 1 shows a device for pulping and conditioning pulp, a plan view; figure 2 is a section aa in fig.t; figure 3 is the same option; on fig.t - device in isometry. The device for pulverizing and air conditioning of cellulose comprises a housing 1 with a loading 2 and an unloading 3 nozzles, mounted in the housing with the possibility of rotation of two parallel augers and 5, which are in engagement with each other and located on the peripheral portions. at least one: from the spiral turns 6 and 7 of the valley 8. The pitch of the spirals of the screws decreases in the direction of material transfer in the device. In the area of each screw, adjacent to the unloading -.pipe, the pitch of the spirals is constant j. This hollow B is located on the sections of the screws with a constant pitch of turns. In the presented construction, the depressions are made in the form of triangular slots. Each auger has rods 9, installed on-forming. According to another embodiment of the device, the rods 9 of each auger are; repaired on its shaft C of FIG. 2). The rods can also be set with a clearance for the shaft: each screw and fixed on the support (Fig. 3). When the rods 9 pass along the axis of the screw along the entire distance between the adjacent flaps of the helix, it is convenient to make the rod No from the connected parts, and the helixs are made with holes for. installation of the rod In addition, the rods can be positioned along the part of the distance between adjacent turns. In other embodiments, the rods 9 and the side surfaces of the protrusions, which enclose the hollows 8 on the spirals of the screws, have surfaces with friction increase notches or the device can be made with removable elements whose surface has the notches and which are mounted on the rod x 9 and / or side surfaces of the projections. For ease of replacement, the rods 9 are mounted on the shaft of the augers t and 5 and / or their coils with the possibility of being removed. The spirals of screws 4 and 5 can also be detachable. The discharge pipe 3 has an adjustable flow area. The screws 4 and 5 have separate coils 10 and 11, cooperating to remove material through the discharge pipe 3. The height and width of the rods 9 can vary from 2 / 3-1 / 3and from 1 / 4-1 / 2 from the height of the helix 6 and 1, the device operates as follows. After the screws are rotated, the pulp is loaded into the housing 1 through the loading nozzle 2. At the moment of loading, the material has a consistency of from 12.5 to 25% solid matter. As the material progresses, the material compresses. Radial compression causes the material not only to be split into fibers, but also that the fibers being processed are crimped or coated with a random orientation of the fibers. When the screws A and 5 rotate, the rods 9 enter the valleys 8. The presence of the rods makes it possible to make hollows 8 large in size without decreasing the throughput of the screws. As a result, increased radial compression of the cellulose is achieved while maintaining a high flow of material through the device, which makes it possible to obtain a mass with separated fibers. Type 1 CMM processing, using this data device .. will allow you to increase productivity and at the same time improve the quality of the finished product. . Claims 1. A device for pulverizing and conditioning the pulp, comprising a housing with loading and unloading nozzles and installed in it with the ability to rotate at least the parallel augers that engage in each other and have peripheral areas at least one of the spiral turns of the hollow, which differs with the fact that, in order to increase the productivity and quality of the product obtained, each screw has rods mounted along its forma- tions in the sections equipped with hollows.
