NOZZLE ASSEMBLY AND SYSTEM FOR SORTING OBJECTS Russian patent published in 2020 - IPC B05B1/30 B05B15/52 

FIELD: soil or rock drilling; mining.

SUBSTANCE: group of inventions relates to a nozzle for ejecting gaseous or liquid media in order to sort objects, as well as to a nozzle device, to a system and method of sorting objects and can be used in mining or in the industry of recycling/processing waste for sorting from the material flow of certain objects. Nozzle device for sorting objects using a gaseous or liquid medium comprises a nozzle unit comprising at least one nozzle, a supply unit, connected to gas supply means for supply of gaseous medium to nozzle block, and fixing plate configured to fix nozzle block in preset position. Single or each nozzle has inlet for receiving gaseous medium, a single outlet having a predetermined cross-section and intended for ejecting a gaseous medium in the direction of the object to be sorted, a channel connecting said inlet and outlet, and an outlet part enclosing at least said outlet. Outlet part comprises flexible material capable of deflecting gaseous medium produced by feed unit, thereby increasing cross-section of said outlet. Nozzle unit is made in form of solid part, in which there are at least two nozzles connected to each other by means of base plate. System for sorting objects using gaseous medium comprises transporting device for transportation of material flow, containing sorted objects, receiving facility for receiving objects that have been sorted, and nozzle device.

EFFECT: technical result of the group of inventions is to reduce the risk of particles and/or dust penetration into the nozzle and enable the nozzle device to function for longer periods without the need to stop the system for cleaning or otherwise servicing one or more nozzles.
