Description

(54) MULTIPLAYER DRAINER

The invention relates to devices for the purification of suspensions from suspended solids, foam, and floating impurities, and in particular for the purification of transport and washing waters of sugar beet factories. There are many multi-colored sedimentation tanks designed primarily for cleaning saturative juices in sugar production, made in the form of cylindrical tanks, divided by conical partitions in height into Russes. The supply of the suspension in them is carried out through the upper preparatory Rus. Further, the sesuspension is distributed over the Rus through the pipe and the radially located pipes attached to it. Scrapers are attached to the pipes to remove sediment from conical partitions. The decantation is removed from each trough through annular flooded tubes 1. When working on suspensions containing fine suspensions, as well as foam and floating impurities, the septic tanks have a low effect of cleaning the suspension due to the fact that the flow rate of the suspension being cleaned into the settling tank is large, and the distance between distribution and intake devices is small. Therefore, the fine suspension is carried by the suspension stream from the settling tank, not having time to settle in it. Foam removal in this sedimentation tank is carried out only from the upper preparatory race. The foam, however, is discharged from the other Ruses; septic tank, goes along with the decantation. Seal condensed sediment in the sump is not provided. There is a well-known multi-stage septic tank for suspended mixtures, mainly for saturation juices of sugar production 2. It is made in the form of a cylindrical tank, which is divided by horizontal conical bulkheads — at a height of Russ. The suspension in this sump is also supplied through the upper preparatory rus. Then the suspension is distributed through the pipes through the pipe and the windows in the pipework. The removal of the decantate from each Russ is made through annular flooded weirs located at the outer walls of the Rus. Foam and floating impurities are removed only from the upper prep. Removing foam and floating impurities from

the steel tanks of the settling tank are not edited, and they are discharged together with the dean's office.

The sediment settled in each russia is scooped up to the central center of the cathode located near the pipe, and the chug is below the openings for starting the suspension, which leads to the dilution of the watering plant, Izprj Myabsa ok-b vydyts rubonro ode, which has an inconsistent weight of 6% of 6% of 6% to 6%. , if the sediment is thick, then it closes the vent pipe. In addition, oh, in the sediment, only large fractions fall out, but faic to mecKDySNer 1SpzveeVyyuSiCi sweat w and susneniyi and leaves with decantation. In this settling tank, electricity is consumed for supplying the suspension and the use of the pipe

Thus, the well-known sedimentation tank for suspension of susceptible suspension and abundant neva, gives an effective effect; The suspension cleaning effect is suspended and does not remove 20 foam and floating time from the shih rus from, stand, as well as the structures of this settler, but not; there is no change of sludge in the co-coax. Such a sediment of 11 ° is given in,; ... further condensed in special machines, 25 (thickeners, vacuum filters, etc.), on that; zlektroznerga consumed. In addition, electricity in a known sediment is spent on the supply of slurry w and vrai to it;

The purpose of the inventions is to improve the quality of the brightened water by increasing the effectiveness of cleaning the suspension from suspensions, ensuring the removal of foam and floating impurities, and increasing the concentration of suspensions in a thickened 35 sediment.

The goal is achieved by installing a settling tank at the inlet pipe, from the side of the branch pipe for feeding the stretch, grill, the blades of which are directed to the opposite direction of the slurry flow, and which reduces the flow rate of the slurry entering the settling tank and contributes to foam. The foam formed with the skin when the slurry s is settled and the r-sump of the sump 45 is separated from the distillate and enters the annular chamber. In 3ty the same chamber is sent from the Russ. The foam in the annular chamber floats on the surface of the water. Together with the foam, part of the fine suspension is removed from the decanter. §about

In connection with the speed of the POT01CJ, the effect of cleaning the suspension ot of suspended solids in rusah increases. The sediment deposited on the bottom of the russes is scraped by scrapers to the center of the settler and enters the shells, the sludge is compacted to KofSpbix until a suspension is high.

The settling tank was driven into rotation by the flow applied to. RTS "suspension of suspension,

and the consumption of electrosurgery for rotation is not required. In addition, the connections for supplying and distributing suspendzin in section, have a triangular shape, which significantly affects the quality of clarified water for COD n BPC, since there will be a fraction of the suspension deposited on the surfaces of these pipes and in the far, rotting (organic matter) and diffusing into the water, with a triangular cross-sectional shape, the sediment will slide down from the surface of the pipe and nbcfyiiaTb into the bottom part of the sump from which it is continuous but it is removed, as a result of which it does not have time to rot, and, consequently, the quality of the clarified water means a lot of work. ,:;,

The drawing shows a multi-colored sediment bowl longitudinal section,:. The overflow is made in the form of a cylindrical tank with a conical bottom 2, separated by a KOHH tecKHMH dividing bed with partitions 3 into Rusa. Above the conical partitions 3 scrapers 4 rotate. They are strengthened on the pipe carrier 5. The settling tank is equipped with an impeller, and the second. The suspension is carried out through the branch pipe 7. The branch pipes of the branch pipe 7 have a bow. | 1l of the distribution of the suspension of the seed roller 6 in the Rus'; pipe D 5 has nozzles 8. The walls of the nozzles 8 also have a slope of 60, For the coarse / shaft 5 heel of the shell 9; for removal of the decanter from Rus, Icetseislefelt weirs 10 and an annular chamber, 11, having a funnel for collecting and removing pits 12, in which the scythe is scraped with a scraper 13, as well as a foam-retaining shield 14. Raised 5 in, spawns, and suspended a bearing, bearing 15, which is attached to the beam 16. The scrapers 4 are suspended from the pipe 5 on the tons 17. The decantatis of the settling tank is the outlet of the pipe 1.

There is a lot of bright sediment as follows.

The suspension to be cleaned is fed through the pipe 7 into the pinch 6, which is part of the pipe and rotates it, which consumes the kinetic energy of the suspension flow, which, therefore, is significantly quenched. Therefore, the flow rate of the slurry after the impeller 6 in pipe 5 decreases and the suspension is dispersed in the settling troughs, the entrance to them through the pipes 8 at lower speeds than in the known settling tank. In addition, after the impeller B, foam begins to flow out of the suspension. The foam continues to be released at the settling of the suspension in the septic tank rushes and is decanted through the annular flooded weirs 10 into the annular chamber 11. In the annular chamber 11, the flow velocity is greater than in rus. The foam, along with it, and part of the fine suspension, as well as floating impurities, float to the surface of the water mirror, ot Kysa, they are dumped with a scraper 13 into the funnel to collect foam 12 and are removed from the sump. The decanter, passing between the foam retaining shield 14 and the outer wall of the annular chamber I, is directed by pipeline 16 to different consumptions. The sediment deposited on the conical partition 1 3 is scooped up by scrapers 4 to the center of the pedestal and enters the shells 9, the volume of which is calculated depending on the concentration suspended solids in a condensed precipitate. In shells 9, the shear of the moving draft occurs. Condensed sediment enters the conical bottom 2 of the settling tank, where its additional compaction occurs. The thickened sediment is removed from the sump. Since the walls of the pipes 8 are equipped with 6 ((the pipe section of the pipe is an equal t | nick), the sediment in the shells 9 slides along the Vfs kgal of the pipes 8, and the scaling does not stay on pipe 7. The positive effect of using 1f lagged settling tank will be expressed by the sign of increasing the effect of brightening susneeisia, as the quantity of suspended matter and foam in the deck will be 2–3 times higher than in the decantation of the Stokes at the same hydral load. sump It comes with a moisture content of 65-75%, while the moisture of condensed sediment from a weighty sedimentation tank is not less than 85%. the drive was truncated.
