    A filter for separating solid bodies such as fish from a liquid stream such as flowing water to be used as a coolant for a power-generating plant comprises a cylindrical housing, an inlet conduit attached to a cylindrical wall of the housing substantially radially thereto, a first outlet conduit connected to a bottom end of the housing for drawing off filtrate, a second outlet conduit connected to the cylindrical housing wall opposite the inlet conduit for channeling away fish-laden effluent, a wedge disposed at the junction of the inlet conduit and the housing for dividing an incoming fluid stream into two equal portions, a filter sieve eccentrically disposed in the housing for forming therewith an annular filter chamber including tapered chamber halves of decreasing width in the direction of fluid flow, and a pair of independently actuatable gate flaps swingably mounted on the wedge for pivoting between respective closed positions engaging the housing and respective fully open positions engaging the sieve. The housing is provided with a trap region at the solids outlet, a plurality of pipe sections connecting the annular filter chamber to the second outlet conduit; the pipe sections contribute to creating eddies at the solids outlet at least in part for cleaning the outer sieve surface during a steady-state operation of the filter. Further steady-state turbulence may be induced by the formation of projections at the free ends of the gate flaps.

    专利说明:

    The invention relates to a device for separating solids (shells, fish, etc.) from a stream, in particular, a cooling fluid of power plants. A device for separating solids from a fluid stream is known, comprising a cylindrical body with a radial inlet for the treated fluid, an outlet connected to the case from the bottom, located on the side opposite to the inlet to the waste channel, separating sieve, the axis of which is parallel to the axis housing, and a guide element placed in the intake channel, the axis of which is parallel to the axis of the housing CiD. A disadvantage of the known devices is that, at entry speeds into the body of less than 2 m / s, the cleaning effect is greatly reduced. The purpose of the invention is to increase the efficiency | of separation. This goal is achieved by the fact that in the device for separating solid substances from the fluid flow, comprising a cylindrical body with a radial inlet for the liquid to be treated, connected to the housing from the bottom, an exhaust patter side located on the side opposite to the inlet to the waste sieve , the axis of which is parallel to the axis of the housing, and a guide element placed in the inlet channel, the axis of which is parallel to the axis of the housing, the guide element is provided with flaps with a pointed and the friction plates that provide turbulent fluid flow, the mounting axles of which are located in the inlet channel, while the flaps are equipped with separate actuators and are installed with the possibility of rotation around the axis. The guiding element is expediently made in the cross section in the form of a triangle with a concave base, the radius of curvature of which corresponds to the radius of curvature of the separating screen, and provided with a guide gate made with the possibility of turning to the wall of the inlet channel. The separating screen can be installed eccentrically in the housing, shifted towards the outlet channel. Moreover, the inlet channel, the housing, the separating sieve and the bypass channel have the same height. FIG. 1 shows the device, a general view; in fig. 2 - the same, horizontal section; in fig. 3 - the same, in one working position; in fig. 4 - the same, in a different working position. The device comprises a cylindrical housing 1, connected inlet radially to the last inlet 2 for the treated liquid, connected to the housing 1 from the bottom of the inlet nipple 3 for the treated liquid and located on the side opposite to the inlet 2 to the side of the waste. A separating sieve 5 is arranged in the cylindrical housing 1, which forms an annular chamber 6 with the housing 1. The 7 axis of the sieve 5 is parallel to the axis 8 of the cylindrical body 1. In the inlet channel 2 there is a guiding element 9, the axis 10 of which is parallel to the axis 8 of the housing 1 and which separates inlet duct 2 into two semi-ducts. 11 and 12. The guiding element 9 is provided with flaps 13 and 14 with sharp, turbulent fluid flow and edges. The mounting axes 15 and 16, respectively, of the flaps 13 and 14 are located in the inlet channel 2. Both the flaps 13 and 14 operate independently of each other, with the half-channels 11 and 12 and the annular chamber 6 alternately locking or adjusting through each gate. 9 is made in the cross section in the form of a triangle with a concave base 17, the radius of curvature of which corresponds to the radius of curvature of the separating sieve 5, which is installed in the housing 1 eccentrically shifted in the direction to the btwot. .. The cylindrical housing 1 has in the area of the outlet channel 4 a drain 18 of waste water. The bypass channel 4 consists of a branch pipe 19 ,. located radially and entering into the drain 18 by the hole-opening element 20. The drain 18 is located along the entire height of the cylindrical body 1, along its entire height there are also several parallel branch pipes 19 spaced from each other. The outlet 3 for the treated fluid is located coaxially to the sieve 5 The inlet duct 2, the cylindrical body 1, the separating sieve 5 and the tapping duct 4 have the same height. The guide element 9 has a guide valve 21. The device operates as follows. The process fluid enters the inlet port 2, passes through separation screen 5, and is discharged through outlet port 3.
    During prolonged or normal operation, both flaps 13 and 14, with their edges, adjoin separate separation sieve 5 (Fig. 3). The flow of liquid is divided into two halves on guide element 9 and flows in semi-canals 11 and 12. In a converging ring-shaped chamber 6, a useful amount of liquid flows through the sieve holes inwards and from there to the discharge port 18 and from there through the branch pipes 19 to the exhaust channel 4. In this mode, the pressure losses are relatively low.
    For contaminants requiring to transport them through the annular chamber b of a stronger turbulent flow, the flaps 13 and 14 are set so that their edges are located in the middle. .
    In the so-called flushing mode (Fig. 4), one of the dampers, for example 13, is turned so that its edge adjoins the housing 1 and thereby locks the passage into the collar b. Another flap, for example 14, is set so that the eie edge divides the space related to it into two identical passes. Guide Element 9
    It has a directional damper 21 directed against the fluid flow and having independent control.
    Due to the installation of the flaps 13, 14 and 21, a strong turbulent annular flow is formed around the separation screen 5, which traps the contamination chamber 6 in the annular chamber. Upon return
    0 one of the dampers in the middle position, the annular flow is braked, and the contamination rushes in the solar cell b to the exhaust channel 4. When 5 contaminants get stuck in the sieve, in the flushing mode
    5, both flaps 13 and 14 alternately rotate from their middle position to contact with the housing 1 and back.
    DI ensure removal of waste. The scientific research institute has a drain 18. Here, vortexes are created in the flow, as a result of which contaminants accumulate near the branch pipes 19 and are discharged outside.
    five
    If the incoming liquid is free of contaminants or has small quantities of them, then a semblance of quiet mode is created, for which the flaps 13 and 14 are turned before their edges come into contact with the separating sieve 5.
