Description

The present invention relates to a discharge of filters for the separation of substances suspended in them from liquids, with automatic removal. deposits formed on the filtering surface.

FIG. 1 shows a vertical section of the filter; in fig. 2 is a horizontal section showing the tube rotation system.

The liquid to be filtered is continuously fed through pipe 75 to tank. The filter elements are the inner tubes 3, which are flared with their upper part 1 in the lid 2, and in the lower part are plugged. Somewhat below the constantly maintained level, the fluids of these tubes have openings that are closed by tight-fitting jackets, the cloth of which is the filtering surface.

These fixed tubes enter the outer rotatable tubes 4, the inner surface of which has inclined diagonal to the forming brush / 5 and the holes of a sufficiently large size, ending at the same height as the holes of the inner tubes. The open ends of the outer rotating tubes slightly protrude above the inclined lid. // The lower part of these tubes 6 is plugged and has at the bottom of the tank /

glands 5. The finger supports of these tubes are provided by the bottom pads 7 at the bottom of the 8 .. The transfer of rotation to the tubes can be the belt 9 and the gear JO.

When the outer tubes are rotated by the brushes, the sediment formed on the inner tube web moves with the brushes upwards and on leaving: tubes 4 falls on an inclined surface //, from which it is washed off by water flowing over this surface or another liquid or is removed by air or gas and leaves into tube J4. These: flush can be sent, if desired, to a smaller control filter. The rotation of the tubes 4 may be periodic, as it forms, a deposit. The filtrate is sucked through the pipes 3 as indicated by the arrows. To observe that the liquid level in the filter does not fall below the holes in the tubes, a float T2 is installed in the tank 7.

The subject matter of the invention.

A filter for liquids consisting of; perforated metal pipes covered with filtering material, distinguished by the fact that the said filter pipes 5 are surrounded by rotating perforated pipes 4, with vinoobrazno. fortified on their inner span

brushes 15, in order to move sediments from the wpyeJ filtering surface up to the inclined surface 11,

With the further removal from the latter of water or other liquid, as well as air or gas through the pipe 14.
