The invention relates to equipment for the separation of liquids in the field of centrifugal force.
The purpose of the invention is to improve the performance of the separator.
The drawing schematically shows a separator, a longitudinal section.
A separator for separating a mixture of liquids having different specific gravities, preferably oil and water, includes base 1, installed
based on intermediate rubber35
The outer gaskets 2 support plate 3, which is attached to the base with screws 4. On the support plate 3, a ring 5 is welded, inside which is installed a casing 6 with an annular seal 0 7 between them. The casing 6 is attached to the base plate 3 by stitches 8, each of which has a sleeve 9 in contact with the console 10.
With the aid of the clamp 8, the sleeve 9 presses against the console 10, fixing the casing 6 on the base plate 3. The latter has a central opening in which the bearing housing 11 with the lower 12 and upper 13 bearings is located. The casing 6 has in its lower part a branch pipe 14 for removing light liquid.
The shaft 15 of the separator is fixed in bearings 12 and 13 of the bearing housing 11, on which the reflector 16 is mounted.
The separator contains a cup-shaped rotor 17 formed by cones 18 and 19 and a flat bottom end wall 20 mounted on a part of the shaft 15 na50

 larger diameter. A cylindrical shell 22 with an inner transverse wall 23 is mounted on the central hub 21 of the lower end wall 20. The rotor 17 has an axially disposed chamber 24 with holes 25 in the upper part of the shell 22 and an upper inlet pipe 26 for supplying the feed mixture to the separation zone.
The rotor is provided with an additional case 28 attached to it with a gap by means of connecting elements in the form of bolts 27, formed by cones 29-32 so that in the upper and lower parts there are narrowing zones and coaxial upper 33 and lower 34 bores, respectively. The diameter of the upper hole 33 for drainage of a liquid liquid exceeds the diameter of the lower hole 34 for drainage of a light liquid, and the diameter of the lower end wall of the 2D rotor exceeds the diameter of the upper hole 33 for drainage of a heavy liquid. The rotor 17 is provided inside with large bases attached to its wall with conical inserts 35-37 having flow-over openings 38 and 39. On the lower end wall 20 of the rotor, a cone 19 and a cone 30 of an additional case 28 are fixed on top, and a cone 31 of the indicated case is below. Additional conical inserts 40 - 43 for separating oil and water, having (besides the first one located near the wall of the body 28), flow holes 44 - 46 are attached to the lower end wall 20 inside the additional body 28.
Additional conical inserts have a variable diameter depending on their height. The bottom end wall 20 of the rotor 17 has an annular opening 47 for the flow of fluid from the rotor to the lower part of the additional body 27. Radial plates 48 - 57 are installed on all the conical inserts 35 - 37 and the additional conical inserts 40 - 43.
The upper part of the rotor 17 is located above the upper opening 33 for draining the heavy liquid of the additional body 28 and forms a throat for mounting the inlet pipe 26.
The additional housing is provided with a device 58 for supplying heavy liquid into the gap between it and the rotor to form a liquid ring before entering the initial mixture of liquids containing pipe 59.
In the end wall 20, holes 60 are provided for passage of peripheral fluid flows between the holes 33 and 34 and the wall of the additional body 28. Radial baffle plates 61 are installed around the rotor throat around the fixed inlet pipe 26, and in the additional body 28 above the light liquid 34 - horizontal annular screen 62. Radial plates 63 and 64 are fixed between the rotor wall 17 and the wall of the additional body 28, the number of which may be different, but, as a rule, there should be four of them. The larger the cross-sectional area, the greater the number of plates required.
The wall of the additional body 28 at the end has a ring 65, which is installed with the possibility of its replacement, for fastening the cross section of the upper opening 33 for draining heavy liquid. An inner 66 and an outer 67 caps are mounted on the fixed casing 6, which are fastened with the help of swivel 8 and clamping nuts 68. The outer cap 67 is provided with an outlet means 69 for draining clean heavy liquids, such as water.
A heavy liquid supply unit 58 is located on top of the outer cap. It also has a screen 70 on which

to the inlet pipe 26 for supplying the initial mixture (water mixed with oil).
At the lower end of the shaft 15 of the separator mounted pulley 71 with a V-belt 72.
Shaft 15 is driven by an engine (not shown).
The separator operates as follows.
The shaft 15 is driven into rotation, with the help of the device 58 through the pipe 59 a clean heavy liquid (water) is fed into the gap between the additional body 28 and the rotor 17, thus forming an aqueous solution. Its formation ends when water flows through the upper opening 33. The water seal prevents the possible release of residual oil into the clean water being removed. Through the inlet pipe 26, a mixture of water and oil is gradually fed into the chamber 24, in which it is rotated, while its pressure rises, and it flows out through the opening 25.
The baffle plates 61 prevent the liquid from entering the screen 70. The initial mixture of liquids enters the rotor 17. Here the preliminary separation of the mixture takes place with the help of conical inserts 35-37. When water flows, part of the oil is trapped by it. The mixture of liquids passes through the opening 38 of the conical insert 35, which is essentially a guide cup, and the oil trapped in water tends to rise to the surface of the conical insert 36 below. Leaking over its surface and flowing over the edge, the liquid enters the conical insert 37. Then the liquid flows down and through the holes 47 in the lower end wall 20 enters the lower part of the additional body 28 of the rotor. Thus, in the upper part of the rotor, there is a primary separation zone, in which primary cleaning of water from oil occurs and an oil layer is formed. The oil in this zone quickly rises to the surface, preventing any sedimentation of solid particles. In the lower part of the additional body, the water tends to flow to the inner surface of its walls, and the oil to the lower opening 34.
Additional conical inserts 40 - 43 provide oil separation.
Water tends to flow to the upper opening 33 as a result of an overpressure formed by the difference in height between the edges of the openings 33 and 34. The separated oil collects and flows towards the lower opening 34. The conical inserts 40 and 42 provide the flow of liquid with some direction upwards, while the particles oils are easier to separate when the flow of water is directed to the upper opening 33. These conical inserts lengthen the distance that the flowing water flows to the upper opening 33, thus achieving a longer separation period.
The clean water rises along the outer surface of the cone insert 40, passes through the opening 60 and is removed through the upper opening 33 by means of the discharge means 69. The separated oil is collected in a layer on the surface of the water and then discharged through the lower opening 34 and the nozzle 14. The radial plates installed in rotor, maintain a mixture of oil and water in a rotating state and thereby provide the maximum centrifugal effect on all diameters.
Using the change ring 65, the diameter of the upper hole 33 is changed, and thereby the specific gravity of the forming oil layer is established.
At the end of the work, the separator rotor is stopped, while water and oil residues flow out through the holes 47, 60 and nozzle 14. Due to the upper surface of the lower end wall 20, the inclined solid particles are removed during the rotor stop. Since the initial mixture of liquids is separated, in the separation process, loose layers are formed, which are mainly removed by stopping the rotor. At the beginning of the operation of the separator, the remaining oil in the lower part of the full-length body 28 is trapped by an annular screen 62. Before stopping the rotor, pure water is separated for some time, as a result of which the oil residues are washed out to a certain degree.
The proposed separator design provides an increase in its productivity as compared with the known separator.
