VIBRATION SIEVING DEVICE Russian patent published in 2020 - IPC B07B1/40 B07B1/46 B07B13/16 

FIELD: mining.

SUBSTANCE: present invention relates to a vibrating sieving device intended for sorting and separation of wet fine particles, can be used for processing mineral raw materials, as well as in drilling industry for drill cuttings removal from drilling mud. Vibrating screening device comprises a support base, at least two sieving decks, which are located one above the other in the form of a unit and each of which contains a sieve frame, a sieve and a chamber located under the sieve surface, a channel for releasing material which has not passed through the sieve, and a channel for discharging material which has passed through a sieve which is connected to said chamber, fasteners, intended for attachment of assembly of said at least two sieving deck to support base, drive support with motor, designed to provide vibration of the assembly of said at least two sieving decks, and a supply unit for feeding the sieved material to each sieving deck. Feeding unit is located on the support base and is movable between the supply position and the maintenance position. Feeding unit is located in the inelastic manner on the support base. Assembly of said at least two sieving decks is arranged on support base in a resilient manner. Said assembly has a first side facing the support base and attached to it by at least one resilient fastener, and a second side opposite to the first side and attached to the drive support. Drive support is attached to support base by means of at least one resilient fastener.

EFFECT: technical result is providing and maintaining uniform distribution of wet fine particles on sieves, as well as compactness of sieving decks and simplicity of their maintenance.
