Description

The invention relates to the purification of liquids from mechanical impurities and from extraneous oils and can be used to clean the lubricating cooling fluids used in metalworking, as well as in other sectors of the national economy, where it is necessary to separate heavier particles of contaminants and more light foreign liquids. A device for capturing a light phase is known, comprising a housing, chambers for supplying and discharging liquid, partitions in a bide of angles with vertices directed upwards, with catching pockets and nozzles for diverting light phase 1. A disadvantage of this device is that it is difficult to return the heavy phase that has come along with the light into the collection, and it is withdrawn along with the liquid phase, which reduces the degree of separation. This device also cannot work when contaminated with liquids by mechanical impurities, since when the partitions are horizontally positioned, the space between them is quickly silted down by settled particles. The closest to the proposed technical essence and the achieved result is a device for cleaning the liquid, containing a tank with a chamber for receiving the source liquid and a chamber for draining the purified liquid with an overflow wall, an oil collection unit with a pipe for its removal, a separation unit as inclined V-shaped inverted elements 2. However, in this device, the separated oil floats up and must be collected from the entire surface of the tank, which makes it difficult to remove the oil, and it can also be carried away by the flow of discharged liquid. All this reduces the degree of separation of the phases. The length of the separation unit is also insufficient for a high degree of phase separation. The purpose of the invention is to increase the degree of separation of the phases and to simplify the removal of the collected oil. This goal is achieved by the fact that in the device for cleaning a liquid containing a tank with a chamber for receiving the source liquid and a chamber for draining the purified liquid with a transferring wall, an oil collection unit with a pipe for discharging it, a separation unit made in the form of inclined-shaped inverted elements, a block The separation is made in two sections, with the lower part of one of the sections communicating with the chamber receiving the source liquid, and the lower part of the other section communicating with the chamber discharging the purified liquid, the oil collecting unit is as placed in the upper part of the separation chamber unit and is provided with a sump uspo- koitelnoy bars, and separating the oil sump chamber and the discharge chamber weir wall purified zhidkosg minute leaching located sump. The device is provided with partitions located at the apex of the angle of the inclined elements in their upper part, and branch pipes, the lower ends of which are fixed on the partitions, and the upper ones communicate with the oil sump. In addition, the upper walls of the chamber, adjacent to the oil sump, are inclined. FIG. 1 schematically shows the proposed device dp cleaning fluid, longitudinal section; in fig. 2 shows the node f in FIG. 1 (on an enlarged scale); FIG. 3 is a section A-A in FIG. 2; in fig. A - section BB in FIG. 2. A device for cleaning a liquid consists of a tank 1 with a chamber 2 for receiving the source liquid and a chamber 3 for discharging the purified liquid with an overflow wall 4. In the tank 1 at the interface between chambers 2 and 3 there is a separation unit 5 consisting of inlet 6 and outlet 7 sections. The lower part of section 6 serves as an inlet for the liquid to be cleaned and communicates with the source liquid receiving chamber 2, and the lower part of section 7 serves as a liquid outlet and communicates with the source liquid withdrawal chamber 3. The tops of sections 6 and 7 are united by a common chamber 8, the upper part of which serves as an oil sump 9. The walls 10 of chamber 8 adjacent to the oil sump 9 are inclined to be inclined to direct the oil sump in the chamber 8 when the fluid passes through this chamber into the oil sump. Oil collector 9 is equipped with a pipe And oil removal. A vent 12 is installed on the discharge pipe. The valve regulates the flow of oil withdrawn from the oil sump. The level at which the oil sump is located is below the level of the overflow wall 4. Separation unit 5 consists of inclined elements 13 having the angle of apex facing up in cross section. At the apex of the angle of the inclined elements 13, in their upper part, there are partitions retaining the separated oil. In the partitions 14 there are nozzles 15, the upper ends of which go out into the oil sump 9. The sump 9 is separated from the steel volume of the chamber 8 by a soothing grill 16, made for example, from plates 17 fixed on patches 15. To clean chamber 2 of the initial fluid from settled loads, a conveyor 18 is mounted in it. The device for cleaning the fluid works as follows. The fluid, contaminated by extraneous oils and particles of mechanical impurities, enters the chamber 2 of the original liquid, where part of the mechanical impurities precipitate. Liquid through the lower part of the inlet section 6. enters the separation unit 5. When fluid flows between the inclined U-shaped elements 13 of section 6, heavy contaminants also settle on the upper surface of element 13 and under the action of gravity slide to the bottom of chamber 2, from where sediment is removed by conveyor 18. Foreign oils in liquid, in the process of its movement between the elements. 13 float and collect on the inner surface of the plate at the apex of the corner. In the upper part of the element 13, the mayleau is retained by the partition 14 and is directed along the nozzles 15 to the mallorboric 9. The fluid flow in the common chamber 8 changes its direction and. between the elements 13 of section 7 moves downwards. The foreign oils that did not have time to separate when moving along the section 7 also rise along the elements 13 and are diverted through the pipes 15 to the oil sump 9. As usual, the specific gravity of mechanical pollution compared to the liquid being cleaned is greater, then mechanical impurities mainly fall on the bottom of the source liquid receiving chamber 2 at the first separation stage, from where they are removed by the conveyor 18. The minor part of the contaminants discharged in section 7 is removed from the drainage chamber of the purified liquid when it is cleaned. A soothing grate 16 consisting of plates 17 fixed to the nozzles 15 separates the oil sump 9 from the remaining volume of chamber 8, prevents oil from being carried away by the flow of fluid passing through chamber 8, and reduces turbulence at the interface between the oil and the liquid to be cleaned. . In addition, this lattice uninterruptedly passes the liquid deposited in the oil sump 9 back to the chamber 8. The cleaned fluid is discharged from chamber 3 through the discharge pipe through the overflow wall 4, and the oil from the oil sump 9 is drained through the nozzle 11 by gravity flow, as the oil sump located below the liquid level in the tank. The discharge oil flow rate is controlled by a valve 12 installed on the discharge pipe. Due to the fact that the separation unit is completed in two sections, above-. The degree of phase separation by increasing the path taken by the fluid and the time of sludge, as well as by reversing the direction of fluid motion. The degree of separation of the phases is also increased due to the fact that the oil separated in the separation unit, through the pipes located on the partitions in the upper part of the plates, flows directly into the oil sump. The bloom of the year between the oil pan and the volume of Kama, in which the liquid to be purified flows from one section of the separation unit to another, is eliminated from the oil pan from the oil tank and at the same time the main liquid that enters the oil pan. in it, unhindered 1131834

but leaves the oil sump through a calming grate.

Due to the fact that the upper walls of the chamber, which unites the upper parts, a closed oil collector is placed, the discharge of the section D and the separation unit is filled below the liquid level in the reaclon, the oil that has fallen into the oil collector is removed.

a chamber with a flow of liquid and separated in it.

In addition, due to the presence of a common chamber, in the upper part of which there is a filling tank, ... the removal of the collected oil is simplified.
