[0037] The utility model sets a frame 201 and an interception net 202, so that if part of the clinker particles carried by the airflow passing through the pipeline body 1 settles, they will be intercepted by the interception net 202, and some clinker particles will not settle to the bottom. These clinker particles can also move with the airflow, thereby solving the problem that some clinker particles settle to the bottom of the pipeline, and too many of these settled clinker particles will affect the normal circulation of the pipeline.
