FILTER FOR PURIFICATION OF THE LIQUIDS OR THE AIR (VERSIONS) Russian patent published in 2007 - IPC B01D29/41 B01D46/10 

FIELD: chemical industry; petrochemical industry; heat-and-power industry; other industries; production of the filters for purification of the liquids or the air.

SUBSTANCE: the invention is pertaining to the filtration techniques. The invention provides, that according to the first version of the design of the filtering package of the filter, in the metal body there is the vertically mounted metal pipe, which passes through the center of the filtering package with the capability of retraction of the horizontally disposed metallic components inside which the metal nets with the cells are mounted. Between the components with the nets there is the filtering fabric laid in several, which layers have various filtering thinness and their external dimensions are corresponding to the geometrical dimensions of the components. The filtering package is placed between two pressure plates, through which central holes the metal pipe is installed. The pipe has the slits for the liquid or the air passing. In the support stand of the body there are the mounted inlet and outlet fitting pipes. According to the second version of the design of the filtering package of the filter the metallic body has the vertically installed metallic stud, which passes through the center of the filtering package with the capability of retraction of the horizontally located annular plates and the intermediate inserts in the form of the ring executed with the equal outside diameters. At that on the surface of the plates there are the grooves for collection of the liquid or the air and there is the laid down in some layers the filtering material with the various combination of the material types, which layers have the different filtering capacity and their diameter is equal to the outer diameter of the annular plates and inserts of the filtering package, which is disposed between two pressuring plates, in the central holes of which there is the rigidly fixed stud having the protrusions for formation of the channels inside the filtering package, and in the support stand of the body there are the mounted the inlet and outlet fitting pipes. The technical result of the invention is the qualitative purification of the liquid or the air, the mechanical strength of the filter and its leakproofness.

EFFECT: the invention ensures the qualitative purification of the liquid or the air, the mechanical strength of the filter and its leakproofness.
