HORIZONTAL BAND FILTER WITH LEVELLING RELATIVE TO VACUUM CHAMBER Russian patent published in 2014 - IPC B01D33/56 

FIELD: process engineering.

SUBSTANCE: invention relates to mechanism used in horizontal band filter for adjustment of drain band for it to be levelled with vacuum chamber. Set of drain band support rollers are arranged at movable structure to displace said rollers so that misalignment between drain holes and vacuum is compensated. Adjustment is executed with the help of transducer to register drain hole position in the band relative to vacuum chamber. Signals are fed to band roller crosswise displacement drive required for levelling said drain holes with vacuum chamber. To ensure uniform distribution of forces along drive pulley and to increase the torque, two-drive is preferably used.

EFFECT: higher efficiency.
