Description

Technical Field

[0001] This utility model relates to the field of iron powder recycling equipment, and in particular to an iron powder recycling and sorting device. Background Technology

[0002] Iron powder, an aggregate of iron particles smaller than 1 mm, is a primary raw material for powder metallurgy. It is conventionally classified into five grades based on particle size: coarse powder, medium powder, fine powder, ultrafine powder, and ultrafine powder. Coarse powder consists of particles ranging from 150 to 500 μm; medium powder from 44 to 150 μm; fine powder from 10 to 44 μm; ultrafine powder from 0.5 to 10 μm; and ultrafine powder from less than 0.5 μm. Iron powder composed of particles with a particle size ranging from 150 to 500 μm is coarse powder; particles with a particle size ranging from 44 to 150 μm are medium powder; particles with a particle size ranging from 10 to 44 μm are fine powder; particles with a particle size ranging from 0.5 to 10 μm are very fine powder; and particles smaller than 0.5 μm are ultrafine powder. The process of separating bulk materials into different particle sizes by passing them through one or more screens is called screening. A screening machine is a vibrating screening device that uses the relative motion between the bulk material and the screen surface to allow some particles to pass through the screen holes, separating materials such as sand, gravel, and crushed stone into different grades according to particle size. The screening process is generally continuous. After the raw material is fed onto the screening machine (simply called a sieve), materials smaller than the screen hole size pass through the screen holes and are called undersize products; materials larger than the screen hole size are continuously discharged from the screen surface and are called oversize products. To facilitate the classification of iron powder, an iron powder recovery and classification device is needed. The screening process in a screening machine is generally continuous. After the raw material is fed onto the screening machine (referred to as a sieve), materials smaller than the sieve aperture size pass through the sieve apertures and are called undersize products; materials larger than the sieve aperture size are continuously discharged from the sieve surface and are called oversize products. Existing iron powder recycling and sorting devices suffer from several drawbacks: inconvenient disassembly and assembly, affecting assembly efficiency; inconvenient replacement of internal screens, affecting screening effect and increasing screening time; and inconvenient internal maintenance, reducing the device's service life.
