Abstract

The invention relates to screen filters, in particular, to cone filters used for the treatment of industrial water and for thickening mixtures transported by water in the chemical industry, nuclear energy and other areas. The invention makes it possible to increase the filter capacity by improving the accumulation conditions of the contaminating particles and their directed removal. This is achieved by the fact that in a pipeline filter comprising a body made in the form of a pipe section, a filtering element in the form of a mesh cone, a forked washer with perforated shoulders and a drainage path, the body is equipped with baffles connected to it placed with a gap relative to the filtering element , the arms of the washer are spiral-shaped, and the axis of the holes of the arms of the washer are inclined toward the larger base of the filter element. 2 Il.

WITH

The invention relates to screen filters, in particular, to cone filters used to purify process water for thickening mixtures transported by water in the chemical industry, atomic energy, and other sectors.

The purpose of the invention is to increase the filter capacity by improving the accumulation conditions of the contaminating particles and their directional removal.

FIG. 1 shows a pipeline filter, a longitudinal section; in fig. 2 is a section A-A in FIG. one.

The pipeline filter contains a filter element in the form of a mesh cone 2 placed in the housing 1, as well as a washing device 3 containing perforated shoulders 4. The washing device 3 is rotatably mounted on the bearings 5. The baffles 6 are connected to the housing 1 and placed with a gap relative to the filter element in the form of a mesh cone 2. The shoulders 4 of the washer 3 are spiral-shaped, and the holes 7 of the perforations of the shoulders 4 of the washer 3 are inclined towards the larger base of the mesh cone Phi truyuschy element is connected to c zeotvod conductive path 8.

Pipeline filter works as follows.

The purified liquid is in contact with the mesh cone 2, on which contaminating particles are retained. The regeneration of the filter element. In the form of a mesh cone 2 is performed by washing

th device 3 pressure jets. At the partition 6, the accumulation of contaminating particles takes place, after which they are transported to the mouth of the outgoing tract 8.

The proposed piping filter improves the conditions for regeneration of the filter element, which leads to an increase in the filter capacity due to the rapid removal of contaminating particles from the mesh surface.
