Abstract

A filter comprising a housing, an inlet, outlet, flushing and drain nozzles, characterized in that in the inner space of the housing limited by its walls and gratings that overlap the inlet, outlet and drain nozzles, there are filtering anti-corrosion spherical elements connected into garlands by strong anti-corrosion threads, in the cleaning mode, the liquids installed with the possibility of tight pressing on top of the movable cover, and in the washing mode - with the possibility of hanging at a certain distance from each other in the form of ryland on a raised movable cover.

Description

The utility model relates to apparatuses of chemical technology and can be used to carry out processes of filtering liquids from mechanical impurities.

A great many designs of filtering equipment are known, both continuous and batch, operating both under vacuum and under pressure.

Of these, the most common are nugg filters, filter presses, sheet filters, cartridge filters, filters with horizontal chambers, drum, disk vacuum filters, carousel, belt, centrifugal, vibration, etc. (see, for example, Kasatkin DG The main processes and apparatuses of chemical technology, Moscow, "Chemistry", 1973).

But some of them are used only for laboratory work and production of low power, others require constant manual maintenance due to deterioration of the filter material, third roads are difficult to operate, have a small resource, are not suitable for use in aggressive environments, etc. There are no reliable filters for cleaning or separating fractions of highly contaminated liquids.

Particularly disadvantageous with the purification of industrial water from shells and other small items in metallurgy, for example, for cooling steel rolling processes, for electrolytic systems or for separating slag fractions when pumping slag pulp in reproduction, for cleaning a salt solution used for regeneration of Na-cationite filters in thermal power plants water-oil emulsion, etc.

As a prototype, a filter for removing mechanical impurities can be adopted, comprising a housing with nozzles and a filter element, which is made of stackable anti-corrosion replaceable plates fixed motionlessly in the grooves or ledges of the housing, which has a rectangular cross section, diagonally and, in which the desired fraction, is filtered , periodic cleaning and self-cleaning are provided by intermediate plates of the required thickness that are rotatable by an angle of more than 180 ° and less than 360 °, which are fixed in the splines of the output shaft with a manual handle drive, or fixed washers laid between each plate (see Patent RU No. 2252543, IPC V01D 29/46).

The disadvantage of the design of the prototype is that the filter element in the form of plates can pass through a long mechanical impurity corresponding to the gap between the plates.

The task to which the proposed utility model is aimed is to improve the quality of the filtering function of the structure, while maintaining the ability to cleanse and self-clean.

The technical result is achieved by the fact that in the inner space of the filter housing, limited by its walls and gratings that overlap the inlet, outlet and drain pipes, there are filtering anticorrosive spherical elements connected into garlands by strong anticorrosive threads, installed in the liquid cleaning mode with the possibility of tight pressing against the movable lid, and in the washing mode - with the possibility of hanging at a certain distance from each other in the form of garlands on a raised movable lid.

In FIG. 1 - shows a filter in liquid purification mode.

In FIG. 2 - filter in the washing mode of the filter elements.

In FIG. 3 is a top view of the movable cover of the flushing pipe.

The filter contains a housing 1, which has an inlet pipe 4, an outlet pipe 5, a flushing pipe 8, a drain pipe 9, and in the inner space of the housing limited by its walls and gratings 6, 7 and 10 there are filtering spherical anticorrosive elements 2 connected in a garland by durable anti-corrosion threads 3 and tightly pressed on top of the movable cover 11 with a screw 12, mounted in the gland seal 15 and the centering elements 14, and from turning the movable cover 11, which together with the screw 12 of the wines oic pair, holds the protrusion 13 in the housing 1.

When using the filter in the liquid cleaning mode, the flushing and drain nozzles overlap, the movable lid tightly presses filter spherical elements against each other in the inner space of the housing, limited by its walls and gratings that overlap the inlet, outlet, and drain nozzles; the liquid from the inlet nozzle passes through the gaps between spherical elements and goes to the consumer through the outlet pipe. After the gaps are clogged with mechanical impurities, the filter switches to flushing mode. To do this, the inlet and outlet nozzles overlap, the flushing and drain nozzles open, the movable cover rises, entraining the garlands with anti-corrosion filter spherical elements, increasing the distance between them so that the flushing fluid introduced through the flushing nozzle easily flushes the mechanical impurity stuck between them . After washing, the movable cover returns to its original position, the washing and drain pipes close, the inlet and outlet pipes open and the filter is ready for further work.
