The. The device of the invention has good flow constant performance, and the practice proves that the direct yield of the product can be increased by more than 7.2%.
【技术实现步骤摘要】
本专利技术适用于料液的恒流量调节,特别适用于稀土冶炼厂主工艺流程中酸、碱体系清液介质流量的恒流量调节装置。稀土生产工艺流程中流量参数不稳定,直接影响最终产品质量的优劣。其原因是,它的萃取流程是恒流量,等比例控制的工艺。不符合这些工艺要求,就生产不出高质量的产品。目前我国稀土冶炼生产流程中,流量控制基本上采用以下几种装置玻璃转子流量计、杯式给料机、分流堰式流量计,比例堰式流量计等。但是都因为它们的性能不理想,造成流量控制达不到恒流量控制的目的。其误差一般都在1~10%之间的范围内波动,从而使产品质量上不去。进一步分析可以看出,产生误差的原因主要是装置的结构不合理。辟如,自动杯式给料机,这种设备结构复杂,体积庞大造成管道过分集中,引起管道下料坡度小或倒坡,以致出现流量不稳定,忽大忽小,使工艺波动大,产品质量不稳定。这种设备的调整主要靠杯子大小,位置等,调整时必须停车,而这种工艺又要求连续工作,不允许经常停开,否则会直接影响产品质量。因此,流量调整困难。当物料的浓度改变而要调整相应流量时,装置显得呆滞。另外杯式给料机为开启式,不密封,加之泄漏点多,跑、冒、漏、滴严 ...
