MAGNETIC FILTER Russian patent published in 2006 - IPC B01D35/06 

FIELD: filters for entrapping solid particles containing ferromagnetic admixtures; cleaning liquids in closed pipe lines.

SUBSTANCE: proposed filter has vertical cylindrical housing with upper and lower covers and two coaxial sections of pipes provided with members for securing them to pipe line. Volume of cylindrical housing exceeds total volume of pipe sections by four and more times. Upper cover is provided with vertical plate located over diameter of cylindrical housing at angle of 45-90° relative to axis of pipe sections at height equal to half height of cylindrical housing and more. Filter element is made in form of screen disk with stiffening members which is secured on lower end face of vertical plate; its diameter is equal to diameter of vertical cylindrical housing. Flat members of magnetic system are located on nonmagnetic rod along axis of vertical cylindrical housing; they may be secured on lower cover and on lower end face of vertical plate.

EFFECT: reduced hydrodynamic drag at increased degree of cleaning; improved service characteristics.
