Abstract
A material casting assembly for a pipe lining apparatus, the assembly having a housing mounted onto an extension/retraction arm and containing an impingement block controlled by an impingement valve, and a static auger bounded by a rotating cylinder which defines a mixing path to an extrusion chamber. The rotating cylinder has exit ports through which lining material is expelled from the extrusion chamber onto a pipe wall.
Claims3
A material casting assembly for a pipe lining apparatus, the material casting assembly comprising:
- a housing mounted onto an extension/retraction arm;
- said housing retaining an impingement block receiving lining material, a static auger, a rotating cylinder, a cylinder motor and an extrusion chamber;
- said impingement block delivering the lining material into a path created by the combination of said static auger and said rotating cylinder, herein the rotation of said rotating cylinder relative to said static auger mixes and propels the lining material into said extrusion chamber;
- said rotating cylinder having a non-apertured portion bounding said static auger and an apertured portion creating exit ports in communication with said extrusion chamber, such that the lining material is expelled through said exit ports.
