螺旋板式高效脂液澄清设备的研制

The Preparation of the Spiral-Board Type of Highly Effective Resin Liquid Settlement Equipment

本文研制的螺旋板式脂液澄清槽，脂液扰动小，基本无“死角”现象，应用于松香生产的脂液澄清过程中，与钟罩式和折流板式澄清槽比较，具有沉降时间短、脂液含水率低、所得松香特级品率高的优点，且设备体积小，加工制作方便。

The spiral-board type of resin liquid settlement tank prepared by the author possesses the merits ofshort sedimentation time，low water content of resin liguid and high rate of special- grade rosin in comparisonwith the bell- jar type and the bending－flow type of settlement tanks in the course of the resin liquid settle-ment of rosin production.
