High Efficiency Screw Screen Machine Used For Separation And Subsequent Dewatering

Screw Screen Machine Used For Separation And Subsequent Dewatering
 
Screw Screens are designed for small and medium sized wastewater treatment plants. The
 
screen is supplied for below ground installation in a concrete channel, or in a stainless steel
 
tank for above ground use.
 
Maintenance is simplified by a unique pivoting system that allows the unit to be raised out of
 
the wastewater flow for cleaning. The ‘screenings,’ outlet pipe can be rotated through 300
 
degrees to suite the site configuration with regards to screen storage and can be fitted with
 
optional de-watering and compaction equipment.
 
working principle
 
Screw screen to the horizontal equipment installed in the drains, the water from flowing into
 
the drum drum ends, the water flows through the grid gate slit, solid waste is filtered in the
 
grid baskets, cleaning arm with a finger in a circular motion when cleaning Grilling gap,
 
rake teeth extending into the grid, the solid was removed when the cleaning arm at the
 
highest point, by the action of water washing and slag plate, remove the garbage down from
 
the rake teeth, and fall into the garbage collection means a screw conveyor bucket, during
 
transport through the variable pitch action is dehydrated at the uppermost end of the
 
compression zone is squeezed, and squeezed the water is returned to the canal, and finally
 
into the garbage container or a successor device, and then processed.
