Propelling unit arrival end is provided with between described material sending warehouse and body.
Described body is corrosion-resistant steel sintered meshwork, the wherein a kind of of sintering PE or sintering PTFE is formed.
Described powder conveying pipeline is that parallel side-by-side arranges at least two row.
Described propelling unit is connected at least two by pipe link.
The present invention also provides a kind of method utilizing powder conveying pipeline as above to carry powder, comprises the following steps:
(1) powder conveying pipeline as claimed in claim 1 is prepared, comprise one end to be communicated with material sending warehouse, the other end and material receive the body that storehouse is communicated with, and described outer surface of tube body is arranged with concentric outer layer pipe, are provided with annular air channel between described outer layer pipe and body; Be provided with at least one propelling unit in described body, described propelling unit comprises diameter and equals the pars intermedia that the forward and backward end of internal diameter of tube body and diameter be less than internal diameter of tube body;
(2) propulsive medium imports between body and outer layer pipe, and enters in body by annular air channel from body endosmosis, makes the powder fluidization of propelling unit front end;
(3) propulsive medium entered in body promotes propelling unit and moves along in body, until the powder conveying of fluidisation is gone out body.
In described step (2), propulsive medium is pressure gas.
The invention has the beneficial effects as follows: the present invention adopts double-skin duct structure, wherein internal layer body is by breathable corrosion-resistant steel sintered meshwork, the wherein a kind of of sintering PE or sintering PTFE is formed, namely body has breathable, and, the present invention arranges propelling unit in body, its propelling unit is the little structure in large centre, two, the structure being formed in body and seal before and after tube cavity, and angle of rake centre does not arrange opening, and the importing of propulsive medium adopts to import between double-skin duct, therefore, when propulsive medium imports between double-skin duct, propulsive medium just can enter in body from breathable body endosmosis, thus by the powder fluidization in body, and promote propelling unit along pipe body movement, until the powder of fluidisation is all transferred out body, it is low that actv. achieves air consumption, conveying completely, noresidue in pipeline, quantitative remarkable result accurately.
