Document Type and Number:
Japanese Patent JPS5845710
Kind Code:
A
Abstract:
An hydraulic system for the discharge of a bed of granular material supported on a screen (3), for example a sand filter, comprises an upright cylindrical vessel (1) with a horizontal plate (2) at the lower end of the vessel to support the bed of granular material. The support plate carries screens (3) to allow the passage of water and to block the passage of bed material. The vessel is provided with entry and discharge ports (8 and 10) and a ring of fluidising jets (13) is located a short distance above the support plate (2). A discharge pipe (11) rises through the bed. The bed of material can be discharged hydraulically from the vessel through the discharge pipe (11) without any mechanical items requiring maintenance within the vessel (1).
