Double-screw extruder and extrusion head structure thereof
The invention discloses a double-screw extruder which is provided with a horizontally-arranged shell, two extrusion rotating shafts are arranged in the shell side by side, screw blades are arranged on the extrusion rotating shafts, an extrusion motor is arranged at the rear end of the shell, and the extrusion motor is in transmission connection with the two extrusion rotating shafts and drives the two extrusion rotating shafts to rotate relatively. A material inlet is further formed in the rear portion of the shell, an extrusion section is arranged at the front end of the shell, the upper end and the lower end of the extrusion section draw close to the middle in the forward direction, the front end of the extrusion section is connected with a forming section of a horizontal straight barrel structure and forms an extrusion head, and a mixing water adding structure is arranged at the position of the extrusion head. And the mixing water adding structure is provided with a water outlet circumferentially arranged around the inner cavity of the extrusion head. The invention further discloses an extrusion head structure of the double-screw extruder. The method can be used for dry production and preparation of the gypsum batten, can realize assembly line automatic production, and has the advantages of simple preparation materials, simple technological process, high product strength, good quality, good process feasibility and the like.
本发明公开了一种双螺旋挤压机，具有一个水平设置的外壳，外壳内并列设置有两根挤压转轴，挤压转轴上有设置螺旋叶片，外壳后端设置有挤压电机，挤压电机和两根挤压转轴传动连接并带动两根挤压转轴相对旋转，外壳后部还设置有物料入口，外壳前端具有一个挤压段，挤压段上下两端沿向前的方向朝中间靠拢，挤压段前端衔接有一个水平直筒结构的成形段并形成挤出头，挤出头位置设置有拌合水添加结构，拌合水添加结构具有绕挤出头内腔周向设置的出水口。其中还公开了该双螺旋挤压机的挤出头结构。本发明能够用于石膏条板的干法生产制备，且能够实现流水线自动化生产，具有制备材料简单，工艺过程简单，产品强度高质量好，工艺可实施性好等优点。
