Description

一种密封的单头螺旋双螺杆
技术领域
本发明专利涉及挤出机机筒领域，尤其是涉及一种密封的单头螺旋双螺杆。
背景技术
挤出机的筒体是挤出机的重要部件，挤出机的筒体和螺杆配合实现对塑料的粉碎、软化、熔融、塑化、排气和压实，因此要求挤出机筒体必须具备耐高温、耐腐蚀的特性，现有技术中的挤出机筒体大多数以氮化钢为原料的一体结构，这种结构耐高温、耐腐蚀性能有限，并且随着磨损深度的增加，需要经常更换。
发明内容
本发明专利的目的是提供一种密封的单头螺旋双螺杆，耐高温，耐腐蚀，使用寿命长。
本发明专利的技术方案是：一种密封的单头螺旋双螺杆，包括铬钼合金筒体和固定于铬钼合金筒体两端的端盖，所述铬钼合金筒体的内腔包括进料段，塑化段和挤出段，所述铬钼合金筒体的内腔内壁中设置有耐腐蚀合金层，所述铬钼合金筒体和耐腐蚀合金层之间设置有一个环形空腔，所述端盖上分别设置有进水口和出水口，所述进水口和出水口与环形空腔相连通，所述进水口与供水管道连接，所述进料段上设置有进料口，所述进料口上方设置有进料斗，所述进料斗中部设置有搅拌装置，所述进料斗上还固定有导流板，所述进料段的内壁上沿圆周方向上设置有若干条槽，以增加物料进入筒体后与螺杆的摩擦力，使得物料不容易打滑，保证了物料前进的速度，从而不影响物料的塑化效果。
进一步地，所述耐腐蚀合金层的厚度为0.5～0.8mm。
更进一步地，所述耐腐蚀合金层的材质为FeNiCrB或NiCrWcCoB。
本发明专利具有的优点和积极效果是：
1、筒体内壁设置有耐腐蚀的合金层，从而使机筒既具备弹性和强度，又具备耐磨耐腐蚀的性能，大大延长了机筒的使用寿命；
2、进料段上设置有进料斗，进料斗内设置有搅拌装置和导流板，装配方便快捷，节省了工作时间，提高了工作效率；
3、进料段的内壁上沿圆周方向上设置有若干条槽，以增加物料进入筒体后与螺杆的摩擦力，使得物料不容易打滑，保证了物料前进的速度，从而不影响物料的塑化效果；
4、端盖上设置有与环形空腔连通的进料口和出料口，在环形空腔内流通循环水可以对机筒进行有效地冷却，使其耐高温。
