Abstract

The invention relates to devices for the purification of liquids from contamination, and makes it possible to increase the efficiency of the purification of liquids with full automation of the process. The device comprises a housing 1 with an inclined bottom 2, vertical plates 3 and 4, installed in the cleaning chamber 5 at a distance from the bottom 2, 6 collecting and oil collecting 7 inclined channels, nozzles 8, connecting young plate 3 with a collecting channel 6, nozzles 9 connecting plate 4 with an oil-collecting channel 7, collection box 10, bucket elevator I with drive 12, scraper conveyor 13, filter 14 in the form of endless belt, flush

Description

chamber 15, nozzles 16, chamber 17 of purified liquid, inclined inlet channel 20 with a separating swirling plate 2}, air distributing devices 25 installed between plates 3 and 4. In the device the liquid flows to the flushing chamber 15, where the pollutants are removed through the oil outlet the channel 23, and the deposited ones slide along the bottom of the channel 20 into the collection container 10. The fluid flow in the channel 20 is twisted by the plate 21 with the direction reversed. When moving between plates 3 and 4 from the downward

upwardly deposited contaminants are discharged through nozzles 8. and channel 6, and pop-up ones - through nozzles 9, channel 7, scraper conveyor 13 into the drain pan. The residual splashed in the liquid is carried by filter 14 to the industrial chamber 15, where. the nozzles I6 are washed and removed through the channel 23, and the purified liquid flows from the chamber 17 through the slotted window 18 into the discharge pipe 22. When cleaning the wastewater, air X must be supplied to the air distribution unit 25 for flotation. 1 hp f-ly, 2 ill.

The simulation is a device for cleaning liquids and can be used for cleaning detergent and wastewater, as well as for washing equipment for maintenance and repair of automotive and agricultural equipment, and also as a stand-alone device for cleaning wastewater of industrial enterprises.

The aim of the invention is to increase the cleaning efficiency.

Figure 1 shows the proposed device, the longitudinal 1st section; figure 2 is the same, top view.

The device comprises a housing 1 with a bottom 2, vertical plates 3 and 4, installed in the cleaning chamber 5 at a distance from bottom 2, loading 6 and oil collecting 7 tilting channels, nozzles 8, connecting plates 4 with oil collecting channel 7, grinding sesbornik 10, bucket elevator 11 with a drive 12, a scraper conveyor 13 connected to the drive 12, a filter 14 made in the form of an endless belt and placed in a washing chamber 15, nozzles 16, a chamber 17 of purified liquid made with a slotted window 18 located below the inlet nozzle 19, inlet n Clones passage 20 having the separation swirl plate 21 and connected to the inlet pipe 19, discharge pipe 22

an oil-diode channel 23 connecting the washings; 5to the chamber 15 and the drain tray 24 of the particles, air distribution devices 25 installed between the plates 3 and 4, the vertical oil drain channel 26, connecting the collecting port 6 and the drain tray 24, the slot 27.

The device works as follows.

Previously, the entire volume of the device through the inlet 19 is filled with contaminated liquid to the slotted window 18. At the entrance to the channel 20, the oily pollutants are removed through the oil drain channel 23, and the settling mechanical contaminants slide along the inclined

the bottom 2 under the separator plate 21 in the dirt 3 for small radius changes the direction of movement from the descending to the upward,

at the same time, the sedimentation on the inclined bottom 2 of the housing 1 occurs. The settling contaminants slide along: the inclined bottom 2 of the settler to the plates 3 through the pipes 8 are fed into

Claims (2)

the inclined collecting channel 6 and sliding into the collecting container 10, where the bucket elevator 1I is continuously removed from the device. Pop-up oily soils in channel 6 are removed through the vertical channel 26 into the drain pan 24. The plates 3 and 4, the pipes and the sloping dirt of the collecting channel 6 are used to continuously remove deposited impurities from the liquid passing through the septic tank to the floating the soils between the plates 3 and 4 are continuously removed through the pipes 9, the inclined oil gathering channel 7, the scraper conveyor 13 and the drain tray 24. When the liquid flow is tightened with a release board 21, the contaminants are removed C into the collecting container 10 through the slot 27. The final cleaning of the liquid is carried out by means of filter 14, where the supernumerous solid particles, hydrophobized by oil pollution, which remain in the solution or wastewater, adhere to the filter tape from the side of the cleaning chamber 5 and take away in the washing chamber G5, in which the part of the solution is washed from the filter belt from the discharge pipeline, with the nozzles 16. The washed out pollutants are continuously diverted through the exhaust duct 23, and the settling ones fall into the inlet The channel 20 is removed in the manner described. The operation of the bucket elevator 11 of the scraper conveyor 13 and the filter 14 must be constant. During wastewater treatment, air must be supplied to air distribution devices 25 at a pressure of 0.29 0.49 MPa (3-5 kg / cm) while reducing the pressure in the sump to atmospheric. The use of the proposed device in comparison with the well-known 1 414 provides a high degree of purification of cleaning solutions and wastewater, economy of detergents, full automation of the process, operation of the washing equipment in a closed water use system and maintenance of automotive and agricultural enterprises. environmental protection measures from harmful effluents containing petroleum products. Formula 1. - A device for cleaning the cleaning solution from contamination, comprising a housing with a sloping bottom, vertical plates installed in the cleaning chamber, a bucket elevator, a filter in the form of an endless belt with a drive, a drain tray of floating particles, a chamber of purified liquid with a discharge pipe and an inlet, This is due to the fact that, in order to increase the cleaning efficiency, it is equipped with a gathering and oil collecting inclined canals, branch pipes connecting the plates with the canals, which are an inclined canal with a separating twisting s plate, scraper conveyor, vozduhoraspredelitelnymn ustroystvamn disposed between the plates, promshnoy chamber with nozzles, communicating with -slivnym tray surfaced particles, the purified liquid chamber vtolnena a slotted window located below the inlet nozzle. 2.
