SHOCK-FREE METHOD Russian patent published in 2021 - IPC B07B1/46 

FIELD: machine building.

SUBSTANCE: disclosed group of inventions relates to a method of securing the sieving module to a sieve screen support. Screen has a sieve panel support and at least one sieving module arranged on said support, wherein sieving module is attached to said support by means of at least one device, which comprises: first element configured to be attached to the sieve panel support and intended to be placed in the opening of the sieving module or in the opening formed by the adjacent sieving modules, second element is designed to interact with said first element to provide attachment of sieving module to sieve panel support at mutual connection between first and second elements. Said hole has the first circle along one part of its axial direction and the second circle along the other part of its axial direction. Second circumference is smaller than said first circle. Hole passes through sieving module or adjacent sieving modules. External periphery of the second element has grooves designed for interaction with auxiliary tool. Method of securing modules fixation to the sieve panel support includes attachment of the first element to the sieve panel support, arrangement of the sieving module hole or hole, formed by adjacent sieving modules around first element, introduction of second element into interaction with first element by interaction of auxiliary tool with at least one groove, made on outer periphery of second element, and creation of screwing movement of said second element. Second element has outer circumference that is larger than said second orifice circumference, which provides attachment of sieving module or modules to sieve panel support.

EFFECT: technical result is higher reliability and safety of securing module fixation on support of sieve panel.
