专利汇可以提供Water filtering apparatus专利检索，专利查询，专利分析的服务。并且Water filtering apparatus having a plurality of tubular filter elements depending into a tank from a vertically movable plate supported by a mechanism for selectively raising and dropping the plate to impact against a stop means to dislodge sludge and solid waste material from the filter elements and deposit the same into an upwardly opening, collection reservoir underlying and communicating with the tank. A sludge compactor includes a cylinder with porous ram to compact the solid waste material dropped from filter elements into a dense wad or cake. The cylinder also has a porous wall portion and in the compaction of the solid waste includes a discharge trap for removal of the sludge cake.，下面是Water filtering apparatus专利的具体信息内容。

权利要求

1. Apparatus for filtering from water particulate materials comprising a water circulation tank, a vertically movable plate having a plurality of holes therethrough, a tubular filter screen depending from said plate at each aperture, spring means disposed to exert a downward force on said support plate when it is raised, means for raising and dropping said plate to dislodge by impact particulate matter trapped on said tubular screens, an hydraulic piston to raise the filter support plate, a shaft extending upwardly from said plate with its upper end terminating in spaced relation to a rod extending downwardly from said piston, coupling means for releasably interconnecting said shaft to said piston rod and being adapted to release said shaft when said spring means exerts a downward force on said plate of predetermined magnitude, said apparatus further comprising a compaction reservoir opening towards said tank to receive the particulate materials dislodged from said filter elements and a porous ram operable to compact said materials into a dense wad.

2. Apparatus as set forth in claim 1 in which said coupling means comprise spring tensioned roller elements carried by a connector affixed to said piston rod, said elements being releasably engaged with an annular recess formed in said shaft to hold said piston rod and shaft in coupled end-to-end, the holding force exerted by said spring tensioned rollers being less than the downward force exerted by said spring means when the movable plate is raised to a given height.
