SU1369759A1 - Apparatus for purifying liquids - Google Patents

Abstract

The invention relates to the field of filtration and can be used both for the purification of working and process liquids, and for the separation and collection of solid phases. The purpose of the invention is the accelerated removal of sediment from the filtration zone and an increase in the efficiency of the filtration process. Through the nozzle (P) of the inlet 3, liquid enters and is filtered out, leaving a load of contaminants on the surface of the filter element (F) 7, and outputted through the P of output 4. In this case, F, made in the form of a screw, is reported rotationally - oscillating motion by means of a cam (to ) 10 through lever 9. Profile K is made in the form of a spiral of Archimedes, the ends of which are closed by a smooth curve, the angle of the spiral being greater than the angle of the closing curve, therefore, when Φ moves against the direction of screw winding, the particles detach from the porous surface and de attracted to the porous surface and are moved further together with F. 2-yl.

The invention relates to filtration and can be used as a means for cleaning working and technological liquids and for isolating and collecting solid phases.

The purpose of the invention is to accelerate the collection of sediment from the filtration zone and increase the efficiency of the process.

Figure 1 shows the device, a general view; figure 2 is the same, top view, and the profile of the Cam.

The device comprises a housing 1, a lid 2 with nozzles of a liquid inlet 3 and a filtrate outlet A, a hopper 5 placed in the lower part of the housing, a drain plug 6 and a filtering element 7 rigidly fixed on the hollow perforated shaft 8, in the upper part of the shaft a lever 9 is fixed, interacting with the cam 10 mounted on the shaft 11 of the drive 12.

The device works as follows.

The liquid enters through the inlet 3, is filtered out, leaving contamination on the surface of the filter element 7, and is discharged through the outlet 4. In this case, the filter element, made in the form of an auger, with the help of a cam 10, via a lever 9 is transmitted a rotational-oscillatory motion. The cam profile is made in the form of a spiral of Archimedes whose ends are closed by a smooth curve 13, with angle Ы. , the sector of the helix is larger than the angle of the closing curve from the cSector; therefore, when the filter element moves against the direction of winding of the auger, 1369759 2 is produced

The particles burst from the porous surface and the particles remain in place, and during the return stroke, the particles are again attracted to the porous surface and move with the filter element.

Then repeats. Thus, the 1Q particles are transported down along the screw surface uiHeKOBoro of the filter element into the hopper 5.

The use of the invention allows to speed up the removal of particles from the filtration zone, collecting them in the bunker and increasing the efficiency of the filtration process.
