Aluminum-based metal powder grading treatment equipment applied to powder metallurgy

Abstract

The invention discloses aluminum-based metal powder grading treatment equipment applied to powder metallurgy, and relates to the technical field of metal powder grading treatment. The aluminum-based metal powder grading treatment equipment comprises a feeding bin, screening bins, crushing bins and grading bins; the multiple screening bins are circumferentially distributed, the screening bins communicate with the lower portion of the feeding bin through connecting pipes and are used for screening the aluminum-based metal powder with the appropriate particle size into a collecting hopper, the screening standard grades provided by all the screening bins are different, thus the aluminum-based metal powder can be directly screened into different grades while screening is conducted, therefore, grading of the aluminum-based metal powder is achieved while screening is conducted, and the grading efficiency is improved; the crushing bins are correspondingly connected to the screening bins through flow guide arm pipes and are used for collecting the aluminum-based metal powders which do not enter the collecting hopper in the screening bins; the grading bins are connected to the lower parts of the crushing bins and are used for continuously grading the aluminum-based metal powder crushed by the crushing bins; and screening of the screening bins and the grading of the grading bins are synchronously carried out.

Description

technical field [0001] The invention relates to the technical field of metal powder classification treatment, in particular to an aluminum-based metal powder classification treatment equipment applied to powder metallurgy. Background technique [0002] Due to its unique chemical composition and mechanical and physical properties, powder metallurgy is widely used in machinery, electronics, aerospace, biology, new energy and other fields. Powder metallurgy includes powder making and products. In the process of producing metal powder, it is necessary to Classify the product. The classification of metal powder can be selected according to its own characteristics. Among them, the aluminum-based metal powder is usually separated step by step by a centrifugal device, and then the classification is realized. The centrifugal separation mainly relies on centrifugal force to throw the larger particles out, while the smaller particles enter the next classification equipment, but the exi...
