    1408155 Liquid aeration plant J R KAELIN 22 Nov 1972 [22 Nov 1971] 53860/72 Heading B1C Liquid aeration plant comprises a tank 3 containing in its lower region a circulator 2 which comprises rotary blades 4 which cooperate with stationary blades 5 secured to the tank, the blades having cutting edges which effect a cutting or sheering action on matter contained in the liquid.' The action of the circulator is to cause a flow movement in the liquid contained in the tank which is shown by the arrows in Fig. 1 i.e. downward coaxially of the tank and upwards around the inner periphery of the tank. An inlet conduit for the supply of oxygen or oxygen mixture is provided and which discharges into the suction side of the circulator upstream of the circulator. The cutting edges of the blades are serrated 9 or formed in a zig-zag manner 10 with one portion of the blade being at a different angle to a succeeding portion which provides a better cutting action in operation in which there occurs successive changes in the cutting angle. The tank may be cylindrical, cuboid or spherical in shape.

    (54) DEVICE FOR CLEANING WASTE WATER
    ; one
     The device is in the field of environmental protection and can be used for wastewater treatment in any industry.
    A device for biological treatment of wastewater is known, which contains a tank, in the bottom part of which a paddle fluid circulation unit is installed with an oxygen supply system or an oxygen-containing mixture 1} placed therein.
    When treating wastewater containing fibrous inclusions, clogging of the circulation unit is possible, which causes disruption of its normal operation and leads to a decrease in the efficiency of wastewater treatment.
    The purpose of the invention is to increase the efficiency of wastewater treatment.
    The purpose is achieved due to the fact that the device is provided with a fixed knife placed above the blade fluid circulation unit, on the inlet side of which has its elastics; cutting edges are made ..
    The cutting edge of a fixed knife can be zigzag-shaped.
    FIG. 1 schematically shows the proposed device, the cut;
    fzg 2 is a section A-A in FIG. one; in fig. 3 is a view along arrow B in FIG. 2
    The device contains a reservoir 1, in the bottom part of which a fluid circulation unit 2 is installed with locks 3, above which an immovable knife 4 is installed, with a zygeag-shaped cutting edge 1 and a system
    10 6 oxygen supply or oxygen-containing mixture.
    In the presence of fibrous inclusions in the liquid being treated, for example, hair or nylon threads,
    15 it is very likely that these inclusions hit the blades of the fluid circulation assembly, which may interfere with its normal operation.
    In the proposed device, the threads falling on the blades of the node 2 of the circulating fluid 20 are subjected to grinding due to the interaction of the cutting edges of the blades and cutting edges: the knife 4, the zigzag form
    25 of the cutting edge of the knife contributes to the fact that the threads hanging on the cutting edge of the rotating blades are captured by its protruding parts and cannot, therefore, avoid the process
    30 grinding.
