Abstract

The invention relates to the field of filtering, in particular to liquid-state filters, and makes it possible to increase the reliability of operation and expand the area of use of the filter. The vibration filter includes a housing 1 with nozzles 6, 12 supplying the source fluid and discharging sludge, an annular conduit 8 for draining the cleaned fluid, a filter element 3 in the form of a cylinder with plugged ends, covered with a filter microgrid, connected by a rod 4 with a vibrator and located in the housing 2 The filter is provided with an inclined filtering grate 15 with a nozzle 16 mounted on the inner surface of the casing 2. The mesh size of the grate 15 is chosen smaller than the size of the annular gap between the casing 2 and the filter element 3. Leather 2 is equipped with an annular collecting trough 13 with a nozzle 14 mounted on its upper edge. The annular conduit 8 for discharging the purified liquid is provided with intake manifolds 9, which are installed along the lower generatrix of the conduit 8. The manifold 6 for supplying the initial fluid is equipped with a manifold socket 7, which is under a layer of liquid. A protective cup 17 is coaxially mounted in the lower conical part of the housing 1, the upper edge of which is located above the upper edge of the nozzle 12 for removing the sludge. The flow of the source fluid to the inclined filter grid 15 provides cleaning from large fractions of the solid phase.

The invention relates to filtration, specifically to liquid filters, and is intended for the purification of liquids and the separation of suspensions in various parts of the lamination.

The purpose of the invention is to increase the reliability of work and expand the use of the filter.

The drawing shows a vibrating filter, general view.

The filter includes a housing 1 and a housing 2, inside of which a filtering element 3 is placed concentrically with a gap, which is a cylindrical frame with agglomerated ends, connected by an IMTO 4 with a vibrator 5. A supply socket 6 is installed at the end of which 7. To drain the purified liquid from the upper part of the filter housing, there is an annular pipe 8 with pipes 9 for collecting liquid installed along the lower generatrix of the pipe 8. The ring pipe 8 is connected to the pipe 10. From water of the purified liquid from the cavity of the filter element is carried out through the pipe 11. The pipe 12 serves to discharge the slime. The floating pollution is removed through the annular tray 13 mounted on the upper end of the casing 2 and connected to the pipe 14. To prevent particles from entering large fraction of the solid phase in the gap between the filter element 3 and the casing 2 and the jamming of the filter element in the cross section of the casing is installed obliquely filtering grid 15, and the size of the grid cell is chosen smaller than The gap between the filter element and the housing. A pipe 17 serves to remove settled large particles from the grill to prevent sedimentation and compaction of the sludge in the center of the body, a cup 17 is provided, the upper edge of which is located above the upper edge of the pipe 12.

The filter works as follows.

The vibrator 5 is turned on, setting the low-frequency oscillations to the filter element 3. The initial fluid entering through the pipe 6 passes preliminary cleaning from coarse fractions on the grating 15. A part of the liquid passes fine cleaning by filtering through the filter element 3 and is discharged through the pipe 11. The other part passes through annular gap.

it is settled and discharged from the upper part of the housing 1 through an annular conduit 8 with nozzles 9 for collecting liquid. Pop-up soils are collected in an annular tray 13 and discharged by nozzles 14. The settled Plam is formed around the beaker 17 and is discharged through the nozzle 12.

Thus, the vibration filter by supplying the initial liquid to the inclined grate ensures the cleaning of the liquid from coarse fractions of the solid phase, which prevents them from entering the annular gap and seizing the filter element, and the reliability of the filter operation is increased. The installation of an annular collecting tray provides for the collection and removal of floating lights, which increases the quality of cleaning and expands the scope of application.
