Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of flotation column, concretely to a sieve plate distributor for flotation column. BACKGROUND

[0002] In the ore dressing process, the flotation column is usually used for screening ore, such as a cyclone microbubble flotation column disclosed in Chinese patent document (application number: CN202323542052.5), which controls two groups of sieve plates by setting six groups of adjusting rods, and the six groups of adjusting rods are separately set to occupy the internal space of the flotation column. The adjusting rod extends into the internal space of the flotation column, which affects the flotation column ore dressing, the microbubble drives the ore to float up, and the adjusting rod is fixedly connected to the bottom of the sieve plate. The sieve plate is not convenient to disassemble and replace, which causes the flotation column to be unable to replace the sieve plate flexibly according to the needs of screening ore types, and reduces the flotation column ore dressing efficiency to a certain extent.
