ABSTRACT:
A filter system comprising a tank and a cage assembly releasably mounted therein. The cage assembly comprises a tube plate and a plurality of filter tubes projecting upwardly therefrom. A plurality of replaceable cartridges are telescoped over each of the tubes. Below the tubes is a plenum chamber for receiving filtered fluid. The entire cage assembly is removable from the filter tank by providing lifting trunnions on the cage assembly and by providing a yoke assembly for lifting the cage assembly out by the trunnions. The yoke assembly will automatically grasp the trunnions when it is inserted in the filter tank. A safety mechanism is provided for securing the yoke assembly on the trunnions.
When the cage assembly is lifted out of the filter tank, a mechanism is provided for automatically tilting the cage assembly to dump the filter cartridges from the cage assembly. The cage assembly is then secured on a pallet which can be moved to another location for reloading clean filter cartridges on the filter tubes. The yoke assembly is then used for the reinsertion of the cage assembly in the filter tank.
