SU1230629A1 - Filter for purifying liquids - Google Patents

Description

The invention relates to a technique for the purification of liquids by filtration and can be used to purify natural and waste waters.

The aim of the invention is to improve the quality of cleaning while increasing productivity and reducing energy consumption.

FIG. 1 shows the proposed filter, general view; in fig. 2 - view along arrow A.

The filter consists of a housing 1, a pipe 2 for supplying the source liquid, a nozzle 3 dp for draining filtrate attached to the opposite walls of the case of vertical partitions 4 with overflow windows 5 separating the housing into sections 6, covers 7, Partitions A are attached to a horizontal partition 8 with openings 9 located in each section. Calming elements 10, made in the form of funnels, having the shape of the upper half of a uni- cavity hyperbola, are attached to the edges of the holes 9. In the sections, volumetric filtering grids 11 are installed at an acute angle to the vertical, the apertures of which are made decreasing in the course of the movement of the liquid being cleaned from section to section. The partition 8 separates the filtering sections 6 from the sludge collector 12 with discharge pipes 13. The collecting tank partitions 14 can also be divided into sections 15.

The filter works as follows.

The liquid to be cleaned through the supply nozzle 2 enters the channel formed by the walls of the housing 1 and the partition 4, rises to a slit-like overflow window 5 in the upper part of the partition 4. Overflowing through it and striking the surface of the removable filter 11 with the cleaning fluid descends at the bottom of the section, where, due to the guiding surfaces, the sedative elements 10 swirl, while increasing the volume of the section reduces the flow rate of the liquid.

Heavy suspensions accumulate on the guiding surfaces of the soothing elements 10 and are deposited through the holes 9 into the sludge trap 12c and then removed through the nozzles 13 from sections 6, the grids 11 are rinsed with a reverse flow of liquid or replaced.
