The invention discloses an iron powder screening device, which relates to the field of iron powder production equipment, and provides an iron powder screening device capable of improving the screening effect of iron powder. The iron powder sieving device consists of a primary sieve, a secondary sieve and a conveyor assembly, a secondary sieve in front of a primary sieve, a conveyor assembly between a secondary sieve and a primary sieve, and a conveyor assembly comprising a frame and a conveyor mounted on the frame. The frame is connected with a steering wheel and a supporting member capable of lifting, which supports the conveyor assembly when the supporting member falls and the roller when the supporting member rises. Supporting conveyor assembly; conveyor can convey coarse material from primary sieve to secondary sieve. The seed iron obtained after the first screening is conveyed to the second screening by conveyor, so that the fine powder in the seed iron can be screened out, and the fine powder can be added to the iron powder screened out by the first screening, thus increasing the output of iron powder. The invention can be used in the design and manufacture of the iron powder production line, and can also be used to transform the existing iron powder production line.
【技术实现步骤摘要】
铁粉筛分装置
本专利技术涉及铁粉生产设备领域,尤其涉及一种铁粉筛分装置。
技术介绍
铁粉产品要求金属铁含量在88%以上,40目筛子筛下比例在95%以上。为保证金属铁含量和粒度的,在铁粉烘干筒尾端采用筛分设备筛分烘干物料,筛分设备采用24目筛网,筛下物料为铁粉,筛上物料为籽铁。实际生产中发现,籽铁金属铁含量为93-94%,籽铁采用40目筛筛选的筛下比例为15-30%,也就是说筛分时并未将铁粉完全筛出,籽铁中仍有大量铁粉存在。由于铁粉售价高,而籽铁售价低,上述情况将会影响铁粉生产企业经济效益。为了将更多地将铁粉筛出,可增加原料筛分时间。但一来,现有铁粉筛分装置是振动筛,原料筛分过程中自动前移,筛分时间调节不便;二来,现有铁粉生产设备是连续作业,铁粉烘干筒不断输送原料到铁粉筛分装置上,如果增加筛分时间,则导致筛分装置上原料堆积,生产无法正常进行或者影响整个铁粉生产设备的生产效率。
