Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a powder screening device for sintering lead-antimony alloy. Background Art

[0002] Lead-antimony alloy is a lead alloy containing antimony used to make lead-acid battery grids and conductive parts. Compared with pure lead, it has a lower melting point, good fluidity in the molten state, is easy to cast, and has high hardness after solidification.

[0003] When the lead-antimony alloy is sintered, the raw materials need to be melted. In order to avoid impurities during manufacturing, the raw materials will be screened. A screening device is needed for screening. For example, the Chinese patent with publication number CN219449814U discloses a raw material screening device for lead-antimony alloy production, including a base and a chassis. The sodium hydroxide inside the shovel contacts the liquid lead-antimony alloy, and the lead-antimony alloy reacts with the sodium hydroxide to generate sodium antimonate and excess sodium hydroxide floating on the surface. The shovel is used to skim off the sodium antimonate, excess sodium hydroxide and impurities on the surface of the melting barrel, and the shovel is rotated to flow the internal sodium antimonate and excess sodium hydroxide to the collection box, and finally discharged from the discharge pipe. The first electric telescopic rod pushes the melting barrel to gradually deflect, so that the pure lead inside the melting barrel is poured out, and the lead-antimony alloy after high-temperature reaction, the screened lead-antimony alloy and fixed impurities are collected in different ways.

[0004] This device performs screening operations in the production process of lead-antimony alloy. Before adding powder, the powder still needs to be screened. At the same time, the sieve holes of traditional screens will be clogged after long-term use, affecting the screening effect. For this reason, we propose a powder screening device for lead-antimony alloy sintering to solve the above problems. Utility Model Content
