A rotary filtration device (20) comprises housing (22) and two en-try means (doors) (24 and 26) that are hingedly attached by hinges (38). Door (24) is rotated closed and then locked shut after the filter packs (not shown) have been inserted into their normal operating positions in the device. Locking is accomplished by means of the cooperation of notches (40) and locking means (42). Door (26) is shown in the closed and locked position. Rotation means (motor) (28) is connected to rotatable shaft (30) (not shown), which shaft is within outer housing (36). Rotating circular members (discs) (32), which have spiral grooves (34), are fixedly attached to the shaft for rotation. During normal operation, plenum (44) (the inter-nal space inside housing (22)), will be filled with feed fluid for filtration. Door (24) is open to allow filter packs singly or a structurally connected group of them in a cartridge to be inserted into normal operating position in the device, after which the door will be closed and locked to maintain the filter packs in place. |
