    The invention relates to the field of blending polymers in the form of a powder with liquids that have a high solvation ability with respect to powders, and can be used, for example, in the chemical industry. The aim of the invention is to increase the homogeneity of the dispersions. A device for continuously obtaining dispersions of powder in a liquid comprises a housing in which a turbine with blades is mounted on the periphery, a powder inlet pipe located along the axis of the turbine, a liquid inlet pipe located against the blades, and a dispersion outlet pipe located tangentially to the turbine. The turbine additionally contains a row of blades placed in its central part against the powder inlet nozzle. The turbine plane can be located at an angle to the vertical. The powdery material and the dissolving mixture are processed in the C turbine by the action of centrifugal forces, and the dispersion is ready to be discharged through the branch pipe under the action of U of gravity. 2 hp f-ly, 2 ill. 35 ND Sl

    The invention relates to the field of mixing polymers in the form of a powder with liquids having a high solvation ability with respect to powders, and may find application, for example, in the chemical industry. The aim of the invention is to increase the homogeneity of dispersions.
    In FIG. 1 schematically shows a device for continuously producing dispersions of a powder in a liquid with a turbine plane located at an angle to the vertical, a section; in FIG. 2 - the same with the horizontal axis of rotation of the turbine. .
    The device comprises a powder inlet pipe 1, a turbine 2 with blades 3 along the periphery and an additional row of blades 4. The turbine is located in the housing 5. The solvent is supplied separately through the liquid inlet pipe 6, mounted perpendicular to the plane of the turbine against the blades 3. The device contains a dispersion pipe 7 located tangent to the turbine. The powder inlet pipe 1 is placed along the axis of the turbine, which is driven by the engine 8. The additional row has twelve blades inclined by 30 ° and is located in the central part of the turbine against the powder inlet pipe 1.
    In one embodiment, the plane of the turbine is located at an angle to the vertical (Fig. 1).
    The pipe 1 is equipped with a worm 9 (Fig. 2).
    The device operates as follows.
    Powdered polyvinyl chloride bbo j is fed into the center of the turbine 2 through the nozzle 1 using a metering pump (not shown) and 5 is immediately brought into centrifugal motion using the blades 4. The dissolving mixture of carbon disulfide - acetone is fed through the nozzle 6 of the fluid inlet to the outside of the turbine at a temperature ambient air.

     CM "The invention relates to the field of mixing polymers in the form of a powder with liquids having a high solvation capacity with respect to powders, and may find application, for example, in chemical industry. The purpose of the invention is to increase the homogeneity of dispersions. FIG. Figure 1 shows schematically an apparatus for continuously obtaining powder dispersions in a liquid with a plane of a turbine located at an angle to the vertical section; in fig. 2 is the same with the horizontal axis of rotation of the turbine. . The device contains a powder inlet pipe 1, a turbine 2 with blades 3 around the periphery and an additional row of blades 4. The turbine is housed in housing 5. The solvent is supplied separately through a liquid inlet pipe 6 installed perpendicular to the plane of the turbine against the blades. 3, The device contains a pipe 7 tap dispersion, located tangentially to the turbine. The powder inlet 1 is placed along the axis of the turbine, which is driven by the engine 8. An additional row has twelve vanes inclined by 30 ° and is located in the central part of the turbine against the powder inlet 1. In one embodiment, the plane of the turbine is located at an angle to the vertical (Fig. 1). Pipe I is equipped with a screw 9 (Fig. 2). The device works as follows. 501 Powdered polyvinyl chloride is introduced into the center of the turbine 2 through the nozzle 1 using a metering pump (not shown, and immediately brought into centrifugal motion using vanes 4. Dissolving carbon disulfide - acetone is fed through the nozzle 6 to inject the liquid to the outer part of the turbine at ambient temperature The rotation speed of the turbine is 3000 rpm. The turbine is inclined by 45 relative to the horizontal. The dispersion is retracted tangentially to the turbine 2 through the outlet 7 of the dispersion outlet, in which it moves under the force The invention claims 1. A device for non-strictly receiving dispersions of powder in a liquid, comprising a housing in which a turbine with blades is mounted on the periphery, a powder inlet pipe located along the axis of the turbine, a liquid inlet pipe placed against the blades, and a pipe for discharging dispersion, characterized in that, in order to increase the homogeneity of the dispersions, the turbine is provided with an additional row of paddles located in its central part against the powder inlet nozzle.
    [2]
    2. The device according to claim 1, about t l and so that the pipe outlet of the dispersion is located tangentially to the turbine,
    [3]
    3. The device according to claim 1, about tl and the fact that the plane of the turbine is located at an angle to the vertical.
