Screw and charging barrel structure for strong-shearing-force chemical reactor

Abstract

一种强剪切力化学反应器的螺杆与料筒结构是在熔融段后端面连通有强剪切段及其强剪切段中的螺杆在料筒内旋转实现强剪切和输送结构;所述强剪切段中螺杆螺棱与料筒螺槽是螺线型结构与直线型结构的组合结构;所述螺杆螺棱与料筒螺槽的头数为5;所述螺杆螺棱与料筒螺槽的升角为40°;所述螺杆螺棱与料筒螺槽的宽度为10时,螺杆螺棱高度是4.5mm,料筒螺槽深度是2mm;且螺杆螺棱与料筒螺槽的旋转方向相反。本发明螺杆螺棱与料筒螺槽采用螺线型和直线型相结合结构,将化学反应器对熔融态高分子材料的剪切性能提高了100%。
The invention discloses a screw and charging barrel structure for a strong-shearing-force chemical reactor. According to the structure, a strong shearing section is communicated with the back end surface of a melting section, and a screw in the strong shearing section rotates in a charging barrel to form a strong shearing and conveying structure; screw edges of the screw in the strong shearing section and screw grooves in the charging barrel adopt a combined structure of a screw structure and a linear structure; the thread number of both the screw edges of the screw and the screw grooves in the charging barrel is 5; the rise angles of the screw edges of the screw and the screw grooves in the charging barrel are 40 degrees; when the width of the screw edges of the screw and the screw grooves in the charging barrel is 10, the height of the screw edges of the screw is 4.5 mm, and the depth of the screw grooves in the charging barrel is 2 mm; the rotating directions of the screw edges of the screw and the screw grooves in the charging barrel are opposite. The screw edges of the screw in the strong shearing section and the screw grooves in the charging barrel adopt a screw and linear combined structure, so that the shearing performance of the chemical reactor on molten state high polymer material is improved by 100%.
