不均匀介质的液面自动控制张冠举（连云港化工高等专科学校）我校在研制实验室型磷块岩浮选机时，浮选的液而高度采用人工控制。由于浮选矿浆经加热、搅拌不断产生浮选泡沫，泡沫又不断被刮出，液面不断下降。为保证稳定的浮选条件，必须不断补充浮选机中的水以稳定液面。... Unevenness of the liquid level automatic control Zhang Guanju (Lianyungang Institute of Chemical Technology) Our school in the development of laboratory phosphate rock flotation machine, the flotation of liquid and highly artificial control. As the flotation pulp by heating, flotation continued to produce foam, the foam has been constantly scraped out, the liquid level continues to decline. In order to ensure stable flotation conditions, the water in the flotation machine must be constantly replenished to stabilize the liquid level. ...
