The invention relates to the field of cleaning compressed air and can be used in pneumatic automation devices and measuring equipment in various sectors of the national economy.

The purpose of the invention is to increase reliability and simplify the design. .

The drawing shows a general view of the filter-moisture separator.

The filter dehumidifier includes a housing 1, made in the form of an inverted glass. In the upper part of the housing 1, the inlet 2 and outlet 3 are made of radial holes with the inlet 4 and outlet 5 mounted in them 5. A glass-shaped metal-ceramic filter 6, through which the inlet 2 and outlet 3 are communicated, is installed along the geometric axis of the housing 1. Between the filter 6 and the housing 1 is installed

impeller 7. A transparent cup 8 is mounted under the body 1 for condensate collection, separated from the body 1 by a flap 9. in which holes 10 are made. At the bottom of the glass 8, the sleeve 11 is mounted coaxially with it and the body 1, coming out of the glass 8 to the outside. A pin 12 is installed coaxially in the axial bore of the sleeve 11, the upper end of which is made in the form of a spherical valve 13 of the axial bore of the sleeve 11. The sleeve 11 and the valve 13 are a filter filter-moisture separator. Above the spherical valve 13 there is a stepped cylindrical section 14. At the lower stage of section 14, a float 15 is mounted, and a large stage of section 14 is slidable in the hole of the disk 16 mounted on the sleeve 11 and serves to eliminate large skews (radial displacements) along VI

melting 15 and limiting its axial stroke. The lower end of the rod 12 is made with a spherical guide along the sky 17. The axial bore of the sleeve 11 under the guide along the sky 17 is communicated through the fitting 18, the air duct 19 and the fitting 5 with the outlet 3 of the filter moisture separator. A radial condensate drain hole 20 is made in the sleeve 11, which connects the axial hole of the sleeve 11 between the spherical valve 13 and the spherical guide plate 17 with the nozzle 21. The filter drier is operated as follows.

Compressed air supplied through the nozzle 4 to the inlet 2, falls on the impeller 7 and moves along a helical line. Drops of water and oil, as well as large solid particles in the air stream under the action of centrifugal forces are thrown onto the walls of the housing 1 and flow down. down into the calm zone separated by the flap 13, i.e. the glass 8. The air cleared of condensate passes through the metal-ceramic filter 6, being cleaned of solid contaminants, and goes to the outlet 3, to the nozzle 5, the air duct 19, the nozzle 18 and the axial orifice of the sleeve 11, creating an impact on the spherical direction pressure, which compensates for pressure drop 17, which acts on top of float 15 and arises due to the difference in effective areas of float 15 on its upper and lower ends. When the level of condensate in the glass 8 rises by an amount whose gping force overcomes the mass of the float 15 with the rod 12, the spherical valve 13 rises together with the float 15 and the condensate under the influence of air pressure in the glass 1 falls into the axial bore of the sleeve 11 between the valve 13 and 17 and from there

enters the hole 20 of the condensate drain and choke 21.

With a decrease in the level of condensate in the glass 8, due to its discharge, the float

15 is lowered and the spherical damper 13 blocks the axial opening of the sleeve 11, after which further draining of the condensate from the glass 8 to its next accumulation becomes impossible,

The air coming out of fitting 18 flows through the gap between the axial hole of sleeve 11 and spherical skirt 17, prevents condensate from accumulating on spherical opening 17, spills it out into drain hole 20, and cleans the axial hole of sleeve 11, thereby eliminating the possibility of loading spherical knowledge of ska 17, which ensures high reliability of operation.
