  • a device for the continuous separation of two liquids of different densities including a reservoir, with a drain compartment, tanks connected in series with vertical separation walls installed in them, level tubes, height-adjustable and brought out from the bottom of the tanks into the drain compartment, a liquid heating system in reservoir, while the device is additionally equipped with overflow pockets with a vertical side slot mounted on vertical partitions, drain lot s located above the pockets and partitions themselves are mounted for vertical movement and biased by the top of the tank (see. Author's Certificate USSR tml. The 01 per 1983 D 17/02).
  • the disadvantage of this type of device is the design complexity due to the introduction of level tubes and a drain compartment, unreliable and inefficient separation of liquids during operation. This is because with an increase in the supply of the mixture to the first container, its speed increases, and the path length remains constant. As a result, the residence time of the mixture in containers along the surface of the vertical dividing wall decreases, does not have time to effectively separate into fractions and flows into the following containers. In addition, the partitions do not have tightness from below and from the sides, which allows the mixture to flow freely into the cavity of the tank behind the partition.
  • the technical result of the proposed device is simplified design, improved quality and increased productivity when cleaning liquids with different densities.
  • the specified technical result is achieved by the fact that in the proposed device for the continuous separation of two liquids with different densities, including a tank with a lid, a supply line and drain pipes connected to it, located on opposite sides of the tank, lower vertical solid partitions fixed to the bottom of the tank and drain trays for overflowing the upper layer of liquid beyond the partitions, according to a utility model, the lid of the tank is removable, on the inner surface of which is fixed There are upper solid partitions connected to drain trays, between each pair of lower and upper reservoir partitions there is a gas line with nozzles, the end of which is located in the area between the ends of these partitions, and between each two adjacent lower partitions there is a liquid level indicator with a lower density.

  • Figure 2 General view of the device with pointers with a local neckline.
  • FIG. 3 is a section along A-A of FIG. one
  • the proposed device comprises a tank 1, inside which vertical lower partitions 4 and 5 are rigidly and hermetically attached to its bottom 2 and its sides 3. Partitions 4 and 5 simultaneously divide the entire internal cavity of the tank 1 into several containers 6, and the depth of the containers decreases from the side wall 7 towards the side wall 8 of the tank 1.
  • the tank 1 On the wall 7, mainly above the largest of the partitions 5, the tank 1 is equipped with a supply line 9 for a mixture of liquids 10.
  • On top of the tank 1 is closed by a removable cover 11 on which the upper partitions 12 and 13 are fixed. Drain trays 14 are attached to the partitions 12 and the other end is connected with partitions 13.
  • the partitions 13 above the trays 14 are provided with through channels 15.
  • Each of the containers 6 of the tank 1 is equipped with an air line 16 located between the lower partitions 4 and the upper partitions 13. At the free end, the line 16 nabzhena injectors 17, the output of which is located below the end 18 above the baffles 5 and the end walls 19, 13.
  • the liquid level gauges 22 In each of the tanks 6 between the upper partition wall 12 in the cover 11 through holes 20 and 21 set the liquid level gauges 22 with a lower density.
  • On the side wall 8 of the tank 1 there are openings 24 and 23 for removing separately from the last tank 6 separately liquid 22 with lower density and liquid 25 with higher density.
  • the mixture of liquids 10 is fed into the tank 1 through the supply line 9 and fills the first of the containers 6 to the level of the lower partition 5, and then pours through its end 18 into the next of the containers 6 and so on to the end of the tank.
  • the mixture 9 takes on a static state and the mixture is divided into the light fraction 22 and the heavy fraction 25.
  • the light fraction emerges on the surface of the heavy fraction and accumulates and is retained by the upper partitions 12.
  • the heavy fraction 25 of the mixture 9 together with the remaining part of the light fraction 22 is poured into following from capacities 6 and from the last already completely cleaned is removed through the hole 24 from the tank 1. This process is carried out continuously and in automatic mode.
  • the light fraction 22 of the mixture 9 can be removed from the tank 1 in two ways.
  • the separated fraction 22 through the openings 15 of the upper partitions 12 flows from the containers 6 and is discharged from the reservoir 1 through the opening 23.
  • the second method for removing the light fraction 22 is as follows. In the upper partitions 12 there are through holes 20, and on the dividing line of the fractions there is a float 21, to which a pump is connected. Moving in a vertical plane, the float 21 automatically evacuates the light fraction 22 from all containers 6 alternately or simultaneously. The solids in the mixture 9 settle on the bottom 2 of the tank and are removed from it by one of the known methods, for example, mechanically. The presence of the air line 16 causes the light fraction to tear into pieces and raise it above the level of the heavy fraction 25, which connects to the already separated light fraction 22 and does not mix with the upper layer of the heavy fraction 25.
  • the proposed device when separating mixtures into fractions allows a more intensive process of separating the mixture, regardless of the amount of the mixture.
  • the device itself is simpler to manufacture and more mobile in comparison with the known designs of devices of a similar purpose.
  • Another advantage of the proposed device is that the movement of liquids inside the tank is carried out without additional devices, which makes it economical in the process operation.
  • the presence of a removable cover allows you to visually monitor the process, monitor the health of all nodes and completely eliminate the ingress of foreign objects into the device, both during operation and in non-working condition.

L'invention permet de simplifier la construction et d'améliorer la qualité du dispositif et d'augmenter ses performances de purification des liquides ayant des densités différentes. Le dispositif de séparation de liquides en continu comprend un réservoir avec un couvercle, une conduite d'amenée et des tubulures de vidange qui y sont reliés et sont disposés des côtés opposés du réservoir, des séparations verticales continues inférieures, fixées sur le fond du réservoir, et des goulottes d'évacuation destinées à transvaser la couche de liquide supérieur au-delà des séparations. Le couvercle du réservoir est réalisé amovible, et a sa surface on a monté des séparations verticales continues supérieures, reliées aux goulottes d'évacuation; entre chaque paire de séparations inférieures et supérieures du réservoir, on a disposé une conduite de gaz avec des gicleurs dont l'extrémité est disposée entre les extrémités de ces séparations, et entre chaque paire de séparations adjacentes on a monté un indicateur de niveau de liquide à densité inférieure.
