METHOD OF MANUFACTURE OF THE FILTERING ELEMENT AND THE DEVICE FOR ITS REALIZATION Russian patent published in 2006 - IPC B29C59/02 B29C53/24 

FIELD: different branches of industry; methods and devices for production of filtering elements.

SUBSTANCE: the invention is pertaining to the methods and devices for separation of liquids and may be used in different branches of industry for purification of the technological mediums from the foreign impurities. The method provides for crimping and thermofixation of the peaks of zigzag-shaped crimps of the filtering element made out of a polymeric thermoplastic filtering material in the compressed state. The thermofixation is realized by a simultaneous heating of all peaks of zigzag-shaped crimps from both sides of the billet of the filtering element up to the temperature equal to the temperature the softening point of the filtering material with the following cooling. The device contains the box shaped body and two systems of plungers. The bottom and the flap lid of the body are made in the form of two in parallel arranged plates. Between the plates edges there is a pair of the perpendicularly mounted to it lateral walls with the butt walls located on their ends. One of the walls is made pushing - movable by the drive coupling rod towards the other opposite support wall along a guiding groove. The plunger systems are made out of the flat shaping elements pivotally linked to each other with a capability to change an angle between them under the action of pressure from the drive coupling rod. The peaks of each system of the plungers contact to the bottom and the lid accordingly, and with the billet of the filtering element located between the systems of plungers. The bottom and the lid of the body are supplied with the heating elements capable to heat up the peaks of the zigzag-shaped crimps simultaneously from both sides of the pressed crimped billet of the filtering element. The invention ensures expansion of the technological capabilities of the single-layer filtering elements with the zigzag-shaped crimps, improvement of their quality.

EFFECT: the invention ensures expansion of the technological capabilities of the single-layer filtering elements with the zigzag-shaped crimps, improvement of their quality.
