喷射式浮选机浸没式充气搅拌装置结构参数的试验

摘要

Introduce the structure of submerged aeration mixing device and comparison with that of long venturi pipe mixing device. Three parameters of venturi pipe including inner diameter, pipe length and distance between pipe outlet and false bottom are determined in optimization experiments of submerged aeration mixing device. FJCA series flotation machine aeration performance index has reached a high level, with characteristics of long service life and easy maintenance etc, and has been promoted in coal preparation plants.%介绍了浸没式充气搅拌装置的结构,并与长喉管充气搅拌装置进行对比.通过浸没式充气搅拌装置结构参数的优化试验,确定了喉管内径、喉管长度及喉管出口至假底的距离3个参数.FJCA系列浮选机充气性能等指标达到了较高水平,具有使用寿命长、维护工作量小等特点,在多个选煤厂得到了推广应用.
