    • 专利摘要:
    An improvement in a decantation cyclone, particularly for the separation of air from material which is light and has a relatively large surface by means of a grid having relatively wide meshes rotatable about an axis which is perpendicular to the plane in which the grid itself lies. The rotation of the grid causes the gradual and continuous displacement of the grid sector from one position which is situated below the mouth of the air-drawing tubing to a rest position.

    专利说明:

    The invention relates to a technique for separating a pneumatic material transported from a gas, for example, from air, and can be used in various technological processes in the chemical industry, in the production of building materials, in incineration plants and in other sectors of the national economy.
    A cyclone with a filter for separating materials transported by air is known, comprising a cylindrical body with a tangential inlet nozzle and with an axial outlet nozzle fixed in the body cover and a mesh disk mounted on a vertical shaft under the output nozzle.
    When transporting materials, such as debris, flaps fall into place, which can be positioned so that the filter screen disk is blocked, the air flow stops, and production stops. .
    The purpose of the invention is to provide a safe and. continuous cyclone operation.
    The goal is achieved by having an aperture in the cover of the cyclone body for the auxiliary air inlet, and the shaft axis passes between the hole in the body cover and the outlet. In addition, on the inner wall of the housing under the mesh disk, a conical ring is placed tapering down.
    FIG. 1 shows a cyclone cut; in fig. 2 - the same, top view; in fig. 3 - modified tclone, cut.
    The cyclone has a body with cylindrical 1 and conic 2 parts. The inlet 3 is located tangentially with respect to the body. In the case cover A, an axial outlet nozzle 5 is fixed, under which the mesh disk 6 is fixed, fixed on the rotating shaft 7. In the cover 4 above the part of the mesh disk 6 there is a hole 8 through which the flow of auxiliary air is supplied. On the inner wall of the housing under the mesh disk 6 is installed a conical ring 9, forming a narrowing 10..
    The cyclone works as follows.
    The air flow along with the transported material enters through the tangential inlet pipe 3 into the cylindrical part 1 of the cyclone tangentially to its inner wall, due to which it receives rotational movement and is separated from the centrifugal forces acting on the particles of the transported material. the latter and along the axis of the housing in its conical part 2 is directed to the outlet nozzle 5 located along the axis of the housing. Before the air flow out of the cyclone, the air is filtered through the mesh disk 6. The flaps and other particles of the material carried along by the air flow are trapped by the mesh disk fixed to the rotating shaft 7. As the mesh disk rotates, part of its surface passes under the hole. 8 in the lid 4 cyclone. The auxiliary air flow enters hole B, which blows the mesh disk clogged with material in the opposite direction, restoring its filtering property. The auxiliary air flow can be created by sucking it out of the atmosphere, if the cyclone is operating under vacuum, or with an additional fan (not shown), if the cyclone is operating under pressure. Among the transportable material, fluffy particles may fall, which are carried along the walls of the body in its cylindrical part 1 towards the outlet nozzle 5 and sucked through the mesh disk 6.
    To prevent this, a conical ring 9 is installed under the net disk, which forms a constriction 10, blocking the rise of material along the walls of the housing.
    The proposed cyclone with a filter allows the separation of a pneumatically transported material, different in its aerodynamic properties, without stopping to clean its filtering part to ensure the safe operation of the fans, whose electric drive becomes unusable when the fan impeller is wedged.
