Description

(54) FILTER

The invention relates to the field of filtering, namely, liquid braid filters, in particular for cleaning water directly in pipelines in various industries.

A filter is known for installation in a pipe hanger, comprising a housing in the form of a pipe section, a filtering element in the form of a mesh cone, a pulverized device made in a tube with nozzles, and a collection of soils 1.

The disadvantage of the filter is that the washing of the filter element and the garbage collection unit is carried out by one washing device, the optimum washing capacity of which is determined by the flushing conditions of the filter element, and the washing of the soil collection is not ensured.

A filter is also known in which the flushing device is made combined in the form of a tubular plug and a tubular ring with nozzles, with the tubular ring placed above the dirt collector 2.

This allows intensification of the pollution collection collector, however, at elevated concentrations of contaminants in the source water, contaminants are removed from the collection. To ensure this, an additional flow rate of wash water is required.

The aim of the invention is to ensure the operability of the filter at high concentrations of contamination in water and to reduce energy costs by improving the removal of contaminants.

This goal is achieved by using a well-known filter comprising a body in the form of a pipeline section, a filtering element in the form of a mesh cone, a collection of ignoor I and a washer, the latter is made in the form of two autonomous and installed inside the mesh cone on a common support mechanism. flushing, one of which is set along the generatrix of the mesh cone, and the other opposite the collector of contaminants. FIG. 1 shows a filter, a general view; in fig. 2 - section A-L nafig. one.

The filter consists of a housing I, a filtering element 2 made in the form of a mesh cone, a garbage collector 3 of the washing mechanism 4 of the mesh cone and a washing mechanism 5 of the garbage collector. The filter works as follows.

The polluted water gets on a cone-shaped net cloth of 2 N, filtering through it, leaving contaminating particles on it. The flushing mechanism of the 4 mesh fabric with its pressure jets pushes the contaminating particles off the grid, clearing it. Under the action of the main stream, the particles rush into the contaminant collector, where they accumulate.

Further, under the force effect of the pressure jets of the washing mechanism 5 of the garbage collector, the contaminating particles are brought into the winding motion (towards the mouth of the garbage disposal path 6).

The design of the device allows to conduct independently) the filtering of the filtering grid and the collection of garbage.

The invention will significantly increase the efficiency of the cone filters, as well as

will reduce the amount of water used on the filter.

Claims (1)

1. A filter comprising a body in the form of a pipe section, a filter element in the form of a mesh cone, a washing device and a soil collection, characterized in that, in order to ensure the efficiency of the filter with high concentrations of contaminants of the source water, to reduce energy costs by improving disposal of waste, the washing device is made in the form of two autoiomic and coaxially installed internal mesh cones on a common support of the washing mechanisms, one of which is set in the image of the skinny mesh cone, and the other is opposite the collection of contamination.
