Description

one

The invention relates to filters for the purification of liquids from mechanical impurities and can be used, in particular, for the purification of water in water supply and sewage systems.

A filter for cleaning liquids is known, comprising a housing and a filtering natron with a surface made of filaments and with end filament holders fixedly mounted.

However, such a filter does not allow for the rapid removal of contaminants during the regeneration period, which is carried out hydraulically.

The proposed filter provides an increase in the regeneration effect and differs from the known one in that one of the holders is provided with a device for its axial rotation.

Effective regeneration is achieved in this design by increasing the gap between the yarns as a result of the axial rotation of one of the holders.

FIG. 1 shows the proposed filter in the working position, general view; in fig. 2 - filter during regeneration, general view.

The filter includes a housing 1 provided with a toothed sector 2 and a nozzle 3 for supplying washing and draining of purified liquids. A filter cartridge is installed in the housing cavity, the working surface of which is formed parallel to the tension of the filaments 4, fastened in the end holders 5 and b, which also perform the function of sounding.

The upper holder 5 is provided with an axis 7, which is hermetically removed through the key of the housing 1. A square 9 is seated on the square head 8 of the axis 7, which is fixed in the slot x 10 and 11 of the gear sector 2 and provides the axial rotation of the holder 5 in the same way nozzles 12 and 13 discharged to the outside of the body and intended, respectively, for the supply of the initial fluid to the well and to drain

wash liquid during regeneration.

The filter works as follows. The initial fluid enters the cavity of the filtering soda and, when it passes through the tensioned filaments, it is 4 degrees. During the filtering period, the handle 9 is fixed after the holder 5 is rotated in the slot 10 of the toothed sector 2, as a result of which the working surface of the natron is formed very close to each other. As the working surface of the cartridge is contaminated with mechanical impurities, it is regenerated. For this, the holder 5 is turned clockwise and the handle 9 is fixed in the slot 11 of the toothed sector 2. As a result, the tension of the threads 4 weakens, and the gaps between them increase significantly. Then through the nozzle 3 a washing liquid is supplied, which washes away the contaminants from the filaments and is withdrawn through the nozzle 13. After the regeneration is completed using the handle 9, the filter cartridge is moved to the working position. The filtering cycle is repeated. 4 Object of the Invention A filter for cleaning liquids, comprising a housing and a filter cartridge with a surface made of filaments and end holders, characterized in that, in order to increase the regeneration effect, one of the holders is provided with a device for its axial rotation.
