Abstract
In a method and a device for extracting liquid or gas from a liquid or gaseous mixture containing dispersed solid particles, a cylindrical filter disposed in a container receiving a mixture to be filtered is subjected to oscillations in the axial direction of the filter while the mesh of the filter is of the size greater than that of particles to be retained on the filter.
Claims11
A method of separating fluids from a fluid mixture containing dispersed solid particles, comprising the steps of receiving and filtering said mixture in a filter body having an elongated filter surface provided with openings which exceed by 10 to 50% a desired size of particles to be retained;
- and in order to prevent the passage of particles said desired through said openings, oscillating said filter surface in its longitudinal direction at a frequency between 10 and 100 cycles per second and at an amplitude between 0.5 S and 50 S wherein S is the desired size of particles to be retained.
A device for separating fluids from a fluid mixture containing dispersed fluid particles, comprising a container for receiving said mixture;
- at least one elongated filter surface located in said container and being permeable to particles of a predetermined minimal size;
- said filter surface being provided with openings exceeding by 10 to 50% desired size of particles to be retained;
- means for discharging a fluid passed through said filter surface;
- and an oscillation generator connected to said filter surface to impact thereto oscillations in longitudinal direction thereof at a frequency between 10 and 100 cycles per second and an amplitude between 0.5 S and 50 S where is said desired line of particles to be retained.
