POWDER CONVEYING/SEPARATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent powder to be conveyed pneumatically from being crushed when being separated by using a cyclone. SOLUTION: This powder conveying/separating apparatus is provide with a conveying pipe 20 for conveying powder 30 pneumatically and the cyclone 22 for separating the powder 30 flowing from the conveying pipe 20 from conveying air. The diameter of a powder 30 inflow port 24 connected to the conveying pipe 20 is made larger as it goes to the side of the cyclone 22. It is desirable that the lower part of the diameter of the inflow port 24 is enlarged and the enlarged diameter of the inflow port 24 is made to be twice to four times the diameter of the conveying pipe 20. The inflow port 24 can be formed from a flexible telescopic pipe. COPYRIGHT: (C)2006,JPO&NCIPI
