    may be screwed to a greater or lesser length.
    The upper end of the auger is located at the free end of the guide lever 22, which is made to rotate by means of an electric motor 23 and a gearbox 24. On the lid 25 of the tank there is a seal 26 preventing the medium from leaving the working space of the tank 2,
    The screw 3 also has a lower rotational drive comprising a hinge shaft 27 of the universal joint 6 fixed in the hollow shaft 28, at the end of which a lantern 29 is located on the flanges, connected to the gear motor 30,
    The screw 3 is rigidly connected to a connecting element 31 having an internal thread-for tightening a finger 32, and depending on the tension of the rotation, the right or left-hand thread is used. On the finger 32 mounted sleeve 33.
    The bearing 5 and the sleeve 34 are positioned without play with the ring 35 on the finger 32. The pin 32 is connected by means of bolts 36 with anti-rotation protection to the upper part of the universal joint 6. The lower part of the universal joint is connected without possibility of rotation with screws 37 s shaft 27.
    On the sleeve 33 there is a hemispherical sealing element 7 with seals 38, which is fixed by means of a flange 39 with a seal 40 and an annular gasket 41. The sealing is done with a ring- flange 42, The screw connection is carried out by means of screws 43, Supplementary lubrication of bearings produced through a blind screw 44 with a sealing washer 45 J "IH through a flexible hose located in place of the screw. An additional seal is provided by a ring 46. During installation, the center of the universal joint 6, as well as the center of the spherical sealing element 7 at one point must be located. In this case, the screw shaft can be positioned at an angle of up to 25 k-vertical axis.
    On the cardan shaft 27 is mounted; without the possibility of rotation of the protective sleeve 47, In addition, the inner ring is mounted on the cardan shaft 27
    3
    the bearing 48 and the pipes 49 are fixed by the ring 50.
    The propeller shaft 27 is equipped with various centering elements for bearings, as well as a threaded axle 51 with a square head.
    The bearing housing consists of the three-body housing 52 of the counter flange 53, also hollow shaft 28, which are welded to each other.
    In the tubular body 52 there are several mounting and control holes, which are closed with several spaced clamp 54, screws 55 and sealing rings 56 arranged according to the bearing housing reference.
    The outer rings of the bearing 48, protected from axial displacement of the retaining rings 57, are inserted into the poly 28. A two-sided axial bearing 58 is placed in the lower part of the hollow shaft 28, a flange 59 connecting the screws 60 with the hollow shaft 28 is installed on the outside.
    The flange 61 of the bearing must be firmly attached to the retaining ring 57, and the axial sub-shaft 58 must be installed with virtually no clearance in the axial direction. In addition, the sealing ring 62 of the shaft is pressed into the hollow shaft 28, and the ball nipple 63 is pressed.
    Thereafter, the drive shaft 27 is inserted. With the help of the clamping washer 64, the spring washer 65 and the threaded nut 66, the hinge shaft 27 is rigidly connected to the axial bearing 58.
    The screw 3 is connected to the finger 32 by rotating the four-shaft shaft 27, and the connecting element is screwed onto the threads of the finger 32. After this, the bearing flange 59 is closed by the cover 67.
    The bearing housing is fastened by a threaded connection with a threaded pin 68, nuts 69 and spring rings 70 to the bottom 1 of the tank without rotation and sealed with a ring 7.1.
    The seal between the element 7 and the bottom 1 is carried out by means of the sealing element 9, the adjusting flange 72 with the ring 73. The element 9 has an internal washing ring 74 for cleaning the element 7 or 9 without dismantling the support assembly.

    communicated with inlet and outlet openings in flange 72 and bottom 1,
    In the adjusting flange 72, several spring-loaded pre-tension screws 75 with a lock nut 76 and springs 77 are located. These pre-tension screws 75 apply pressure in the lower direction to the adjusting flange 72 with the sealing element 9, pressing it against the sealing surface of the element 7.
    During operation of the mixer, the screw 3 rotates around its axis, and also performs swinging movements around the axis of the conical tank 2, because the swinging movement makes the hemispherical sealing element 7 connected to the screw, due to the design of the lever mechanism 10. The lever mechanism provides the necessary stroke of the sealing element 7 , prevents its possible turning and prevents the screw axis from tilting. The length of the lever mechanism can be changed to match its operation with the various strokes of element 7, if the structure must be, for example, embedded in a tank with conical CTtjHKaMH, which have a different slope.
    The lever mechanism 10 in the extended position is depicted in Figure 1 as a dashed line.
    Opposite the sealing element 9 there is a stationary sealing flange 78 fixed on the flange 79 of the bearing.
    Figure 4 shows the positions of the element 7 when rocking.
    Such an attachment of the hemispherical sealing element 7 has a substantial advantage over the known device, since the friction forces between the sealing element 9 and the sealing element 7 must be greater than the friction forces due to the bearing 5 and the seals 38 and 40..
    By fixing the anti-rotation of the sealing element 47, it is possible to introduce lubricant and coolant through flexible hoses into the bearing between the sealing element and the screw shaft. Due to this, the bearing service life is significantly prolonged and operational reliability is maintained, while the possibility of contamination of the product in the tank with lubricant or coolant leaving the bearing is excluded.
