PTA下料系统对配浆量比的影响

The influence of PTA feeding system on the amount ratio of slurry preparation

在PTA浆料配制时,出现PTA下料量显示不准,其浆料密度持续偏离的现象。找出原因为PTA下料时废绳头缠绕测量轮和PTA平衡软管失效。采取措施为PTA料斗内隔离筛网孔径变小,筛网四边与料斗四壁满焊,将帆布软管换成金属缠绕的透明软管,并2 h氮气吹扫1次。

In the preparation of PTA slurry, there is a phenomenon that the PTA amount is not allowed and the slur- ry density is continuously deviated. The causes are found out that the waste cord wound around the measuring wheel when the PTA feeding and the PTA balance hose failure. The taken measures are to make the aperture of the PTA hopper isolation screen smaller, the four sides of the screen and the hopper wall full welding, replace the canvas hose with a metal wrapped transparent hose, and nitrogen sweep one time in 2 h.
