SU837358A2 - Filter for cleaning liquid - Google Patents

Description

The invention relates to the technique of cleaning liquids by filtration and can be used in various industrial plants, in particular for wastewater treatment mainly from villages and oil products. According to the main author. St. No. 735277 is a known filter for cleaning a fluid, comprising a housing, a filter bag mounted on a shaft rotatably, nozzles for supplying a source and discharge filtered fluid, a telescopically mounted perforated tube inside the filter bag and an inverted spring-loaded cup Cl. When such a filter is operated, under By the flow of the filtered liquid, the filtering powder, which is placed in the cavity of the filter bag, is partially compressed, its volume decreases, and thus conditions for its creation are created. displacement in the cavity ggket. As a result of this, the filthyrone scoop in some places of the bag is placed thicker, in others - in a thinner layer, and in some places there forms Ravine, which facilitates the passage of untreated sewage and a decrease in the quality of their purification. The purpose of the invention is to increase the efficiency of the filter. This is achieved by the fact that the device is equipped with an elastic permeable shell placed on the outer surfaces of the perforated tube and the inverted spring-loaded glass, and elastic partitions installed inside the filter package. FIG. 1 is depicted. filter, general view, with filtrats, AI, in FIG. 2 filter, general view, during regeneration; in fig. 3 shows the fastening element of the movable end of the filter bag; FIG. 4 filter, cross section. The filter for cleaning the fluid includes a housing 1 in which the filter bag 2 is placed, made of elastic shells 3 and 4, the annular cavity between them is divided by elastic radially mounted partitions 5 into chambers b filled with elastic filter crumb 7. A perforated tube is placed inside the filter bag rG. 8 and an inverted performer {nozzle 9). The glass 9 is equipped with a spring Y. A housing 11 is placed on the housing for supplying the initial liquid for cleaning, inside it there is a connection 12, on which it is installed possibility of movement of the filter bag 2. The branch pipe 12 has longitudinal projections 13, which fit into longitudinal grooves 14 of the pipe 8. conduit 12 connected manifold 15 for retraction; purified liquid; and nozzle 16 for withdrawing the regenerator. At the bottom of the Kopiiyca 1 is placed the pipe 17 for discharge of the regenerator. The upper part of the filter bag is attached to the shaft 18, which, by means of gears 19 and 20, is connected to drive 21.

When filtering the original fluid

The nozzle 11 enters the cavity of the housing 1. From the cavity of the housing 1, the initial fluid passes through the outer shell 3 into the chambers 6 filled with filtering chips 7. From the chambers 6 the filtered fluid passes through the inner shell 4 and is discharged through the perforated cup 9, the pipe 8 and nozzles 12 and 15. Passage through the filter bump 7, particles of petroleum products present in the source liquid are delayed in the pores of the filter cartridge. After filling the filter crumbs. Oil products are used to regenerate the filter. For this, the drive 21, the gears 19 and 2O, and the shaft 18 are connected to the filter bag.

rotational movement, due to which the package is twisted and compressed. When compressing the filtering substance, particles of oil contained in its pores are squeezed onto the outside surface of the package, flow down to the lower part of the cavity of housing 1 and are discharged through the branch pipe 17, and out of the perforated cup 9 is drained nozzles 12 and 16. After regeneration, the filter is again: switched to filtration mode.

Supplying the filter bag with an elastic, water-permeable shell placed on the outer surfaces of the perforated tube and inverted spring-loaded cup, and with elastic partitions radially installed inside the filter bag, allows the filter layer to form a uniform thickness across the filter surface, which prevents leakage through the filter wastewater that does not clean the wastewater. the quality of their cleaning.
