SLUICE ROTOR FOR HIGHLY HEATED RADIOACTIVE BULK MATERIAL Russian patent published in 2021 - IPC B65G53/46 

FIELD: bulk materials handling, unloading, loading and transporting.

SUBSTANCE: invention relates to equipment for handling, unloading, loading and transporting bulk materials, in particular for dosed unloading from bunkers and feeding highly heated radioactive bulk materials into transport pipelines and containers, and can be used in the energy industry, building materials industry, chemical industry and others branches of the national economy. The sluice rotor for highly heated radioactive bulk material contains a cylindrical body, communicating with the body, coaxial and vertically oriented inlet and outlet pipes, means for coaxial positioning of the rotor inside the sluice body and means for sealing the working part of the rotor inside the sluice body. The rotor of the sluice gate in the working part placed in the body of the sluice is made in the form of a cylindrical drum with cavities for bulk material located longitudinally on its cylindrical surface, along the edges of which beads are made with protective grooves located behind them, made with the possibility of free pouring out of them displaced from the cavities on the surface of the drum into the running clearances between the beads and the body of the sluice gate of small particles of bulk material, down into the outlet pipe through the recesses in the lower edges of the connection of its neck with the body. The cavities located longitudinally on the cylindrical surface of the drum and the beads located behind them are made with a total length greater than the inner diameter of the supply and outlet branch pipes of the sluice gate.

EFFECT: increased efficiency of rotor functioning when working with (highly heated) radioactive bulk materials heated to temperatures of 200-500°C and more.
