Coaxial arrangement.
Moreover, being equipped with zigzag overflow weir at the top of the annular overflow trough.
The advantages of the utility model and good effect are：
The utility model is a kind of special settler of milk of lime enrichment, and external low concentration lime slurry is carried out enrichment,
The lime slurry of normal concentration is obtained, saponification is carried out.The external world come low concentration lime slurry by pond central upper charging
Distribution apparatus enters in pond, by standing sedimentation, most of solid lime precipitation to pyramid type bottom of pond, and rake stirring dress in pond
The speed reducer driving rotation filled on pond is set, the rake teeth of agitating device lower part is close to bottom of pond, scrapes bottom of pond milk of lime and moved to center
Dynamic, pond centre bottom is equipped with pyramid type and collects drawing mechanism, collects the lime slurry after enrichment and is flowed out outside settler by pipeline, i.e.,
It can obtain meeting the raw material milk of lime that propylene oxide by chlorohydrination prepares certified concentration.
The present apparatus is easy to use, high degree of automation, solves problems of the prior art, to propylene oxide
The yield and quality of product play the role of good.
