FLUID FILTERING SYSTEM Russian patent published in 2016 - IPC B01D27/00 B01D29/11 

FIELD: process engineering.

SUBSTANCE: invention relates to filtration. Filtering assembly comprises liner (36) to define the inner chamber (40) and liner axle. Filtering medium (34) surrounds the liner. End plug (32) secured to the liner and comprises the components that follow. The first element (46) extends across the filtering medium, sidewall (48) perpendicular to said first element (46) and extending in the first direction, outer wall (54) spaced from the first element, in fact, parallel with the liner axle. Note here that the second wall (54) extends in the second direction, from the filtering medium (34) and opposite the first direction. Several braches extend from the sidewall (48) to outer wall (54). Note here that said branches and sidewall as well as said outer wall define the bores in the end plug (32). Every said branches comprises the rib-like section extending in the first direction and including the first and second lower surfaces. The procedure of fitting the filtering assembly in the fluid filtering system consists in that the filtering assembly is directed into the tank by a proper positioning of the skewed lower surface of the end plug nearby the tank inner wall. Said filtering assembly is fitted in the tank unless the first seal contacts with the tank. Said tank is secured at the bed unless the matter contacts with the end plug upper part and the first radial seal is fitted between the bed and the second seal. After the first radial seal is fitted in place the tank is secured at the bed unless the second radial seal is fitted in place with the help of the first sea; between the end plug and the bed. And unless the first axial seal if fitted between the first seal and the tank.

EFFECT: reliable installation of filtering assembly.
