FILTERING ELEMENT FOR USE IN FILTERING DEVICE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; filtering devices. SUBSTANCE: invention relates to filtering element provided with central hole 16 and designed for assembling with other filtering elements of same type to form filter. Each filtering element 1 has two sides, namely, inner side 2 and outer side 3, inner rim 5 limiting periphery of central hole 16 and outer rim 4. Gauze 6 is installed between inner and outer rims in parallel with inner and outer sides 2, 3. Each side of filtering element is provided additionally with radial spokes 72, 73 passing opposite to each other between outer rims 4 and inner rims 5 to form angular sectors 21, 31 on inner sides 2 and outer sides 3. Design peculiarity of filtering element is that its each inner side 2 and outer side 3 contains at least sixteen angular sectors, each being formed by free surface of gauze 6. Ratio of free filtering surface of gauze 6 to total surface of element 1 is within 55 and 68%. EFFECT: improved capacity at provision of adequate rigidity of structure. 7 cl, 3 dwg
