Abstract
A water-solids separator including a casing forming a reservoir and having an inlet and an outlet, a perforated filter screen assembly positioned in said casing between said inlet and said outlet, an overflow weir in front of the outlet to define the depth of water in the reservoir, a baffle plate on the inlet side of said filter screen assembly to direct incoming water toward the filter screen assembly and a conveyor assembly on each side of the filter screen assembly for cleaning the surfaces of the filter screen assembly, each conveyor assembly including a number of wiper blade flights located in positions to move in abutting engagement across the surfaces of the filter screen assembly, each flight including a resilient wiper blade or brush to clean the perforations in the filter screen assembly.
Claims18
A water solids separator comprising
- a casing having an inlet and an outlet,
- a filter screen assembly located in said casing between said inlet and said outlet,
- said assembly including a perforated screen member,
- means mounted in said casing for simultaneously wiping the surfaces of both sides of said screen member,
- said wiping means including at least one wiper blade assembly located on each side of said screen member in opposing relation,
- each wiper blade assembly including a resilient wiper blade,
- conveyor means for supporting said wiper blade assemblies for movement across the surface of said screen member with the wiper blades arranged to move into abutting relation in the perforations,
- and drive means operatively connected to drive said conveyor means whereby said resilient wiper blades will squeeze any foreign material from the perforations in the screen.
A water-solids separator comprising a housing having a back wall,
- an inlet and an outlet,
- means for supporting the housing with the back wall in an angular relation to form a beachplate, said inlet being located above the outlet,
- an overflow weir mounted within said housing above said outlet,
- a filter screen assembly positioned in said housing in a parallel relation to said back wall between said inlet and said weir,
- said screen assembly including a perforated screen member, whereby waste water admitted to said housing passes through said perforations in said screen member assembly and over said weir for discharge through said outlet,
- and wiper blade means located in said housing in a position to wipe both sides of said screen member, said wiper blade means comprising an endless conveyor assembly on each side of said screen assembly, each assembly including a number of resilient wiper blades, said blades on each conveyor assembly being mounted for movement into abutting engagement with a corresponding wiper blade on the other conveyor assembly whereby said wiper blades will come into contact in each of the perforations in the screen assembly.
A waste water-solids separator comprising
- a housing having front, back, side and bottom walls forming a settling tank,
- means for supporting said housing with the back wall in an angular relation to the floor,
- an inlet and an outlet to said housing,
- a filter screen member supported in said housing in a parallel relation to said back wall to filter solids from the waste as the water flows from the inlet generally upwardly through the screen member to the outlet,
- said screen member including a plurality of perforations,
- an overflow weir in front of said outlet, and wiper blade conveyor means mounted in said housing to simultaneously wipe both surfaces of said screen member,
- said wiper blade conveyor means including a number of resilient wiper blades arranged to move into abutting engagement in said perforations of the screen member.
