FILTERING COLUMM

摘要

This appratus is for filtering of high temperature and press ure heavy fuels. A column(11) has multiple holes(12) and a bead (13) to fix it with the hollowed portion(14) of a closed socket (15). The socket has an extended portion(16) and a pressed coil spring(17) is established around it by an extruded portion(18). A ring pile body(20) is established around the column and supported by the flange(19) of the socket and fixed by a metal ring(21) to the column. The upper end of the column is expanded to prevent the ring(21) from slipping out. The ring pile body can be moved between the upper end of the column and the ring.
