    A device for recovering cleaning particles from a liquid stream after it has traversed a heat exchanger, comprises a pivotable inclined sieve and a baffle plate upstream of an outlet and the lower edge of the sieve for generating between the plate and the sieve a vortical flow which induces the particles to flow downwardly along the sieve to the outlet.

    2. The device according to claim 1, wherein the guide plate is made in the form of a curved sheet, the radius of curvature of which intersects the axis of the body.
    3. The device according to paragraphs. 1 and 2, characterized in that the guide plate is made with a curvature corresponding to the elliptical slot of the separation screen.
    4. Device on PP. 1-3, which is due to the fact that
    The invention relates to a filtering technique, in particular, to a device for separating the cleaning bodies from the flow of a winding cattle behind a heat exchanger, and can be used in power plants.
    The purpose of the invention is to prevent the deposition of soil particles.
    FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. 1, in FIG. 3 shows a section BB in FIG. one,; in fig. 4 shows a variant of the device with two separation screens. General view.
    The device contains cleaning bodies 1 in a cooling water flow 2 behind a tubular heat exchanger, a cylindrical body 3 with a horizontal axis 4, one or more separator sieves 5 rotated around an axis, a guide plate 6 above the separating sieve and a drain 7 for cleaning bodies.
    The separating sieve in the position of the separation of the cleaning bodies adjoins the lower edge 8 to the corresponding elliptical socket 9 in the housing, and in the zone of the lower point 10 of the sieve to the outlet for the cleaning bodies.
    The guide plate is placed orthogonal to the plane of the separation screen and forms its slit 11 across the width of the screen for the passage of cleaning bodies.
    The surface 12, on which the flow rushes, is positioned so that the shield forms a wedge space 13 with the body, open towards the separation sieve, and the creating shield is made with the same width along the entire length.
    5. Device on PP. 1-4, characterized in that the guide plate is made with a longitudinal bend in the zone facing the outlet
    for cleansing phone
    6. The device according to paragraphs. 1-5, characterized in that the guide plate is provided with end-elements in the end zones.
    There is a rarefaction zone, as shown by the swirl stream 14 streams.
    The guide plate is made in the form of a curved sheet, the radius of curvature of which intersects the axis of the housing 15, and the curvature of the shield corresponds to the elliptical housing of the housing. The guide plate can be
    made with the same width along the entire length and have closing elements 16 directed to the body and preventing the incident flow of liquid into the space
    dilution
    In the area facing the discharge of wastewater bodies, the guide plate
    may have a horizontal section 17 or a buckling may be provided there.
    The device can be made with two separation screens, which are connected at the apex and made semi-elliptical.
    The guide plate can be installed in the housing slot 18, with double lines 19 showing that the guide plate can be pushed into the housing to a different depth. The edge zones 20 of the separation screen are adjacent to the wedge-shaped sections 2 of the body.
    The device works in the following way,
    Liquid with cleaning bodies 1 in the form of balls, which during the cleaning period pass through the connected tubular heat exchanger, get into the flow of cooling water 2 into the body
    3, where the separating sieve 5 is captured and fed to the outlet 7 for the cleaning bodies. In the separation position along with the coolant, contaminants that settle on it can also fall on the separation screen. The guide plate 6 delivers the cleaning bodies 1 to the outlet 7 by creating a vacuum area behind it along the entire length of the slot 11 through which the cleaning bodies pass. At the same time, an intense whirlpool is formed in the zone between the gap I1 and the socket 9 along the entire length of the guide plate, which prevents sedimentation of the contaminants on the separation screen 5.
    To remove the remaining contaminants, separation screen 5 can be rotated around axis 4, while cleaning the heat exchanger
    interrupted, and the passing water washes away seeding.
    The different performance of the guide plate is determined by the following reasons.
    In the case of a small size, the shield can be made in the form of a flat sheet. The flap in the form of a curved sheet, the radius of curvature of which intersects the axis of the body, has a stronger effect on the flow. In order to make the described cycling action more intense, it is recommended to carry out a current with the same width along the entire length or with a longitudinal bend in the zone facing the outlet for the cleaning bodies. The supply of the condom zones of the guide plate with the locking elements prevents the entry
    fluid into the dilution zone and increases the effect of separation of the bodies from the fluid.
