wwtp clean waste water pretreatment automatic metal mechanical rotation trash rake bar screen Italia

YMGS serial rotary bar screen mainly composed of driven device、rake tooth facility 、Flush facility etc, which is assembled to be a group of rotary grille chain by a unique rake tooth, driven by Motor reducer, the  rake tooth chain going  Rotary motion as reverse flow.

When the rake tooth chain operate to upside of equipment, due to the guiding of Geneva wheel and curve, which produce the relative self-cleaning motion between each group rake tooth, most of the solid drop down by gravity. Another parts clean up the sundries sticking in the rake tooth by sweeper ‘s Reverse movement.

Rake tooth chain similar to grilling by water flow direction, the rake tooth clearance which assembled  in rake tooth chain shaft can be chose according to usage condition; Which can guarantee water flow pass by smoothly after the rake tooth separate the suspended solid in the fluid. the whole process can be continuous and intermittent.

Characteristic

The maxi advantage of the equipment is high Automaticity ,high separative effiency, small power consumption,no noise、Good corrosion resistance,can ensure continuous steady operation without unserviced, set overload safeguard device,when the equipment out of order, can give a sounding and light alarm and stop operating automatically ,can avoid equipment working overload. This equipment can

adjust operation interval at will according to user’s request,achieve operation periodic; can automatic control according to the  before and after  grilling liquid level difference ;with the function of manual control,in order to overhauling convenient.user can chose at will according to different work demand,

As the equipment structure design rational, with stronger self-cleaning ability, won’t appear blocking, few daily maintenance work.

Such equipment specification can divide YMGS300-1500 according to width, the equipment width exceed 1500mm, cab be made into parallel machine, the clearance of a grille can divide into 1mm,3mm,5mm,10mm,20mm,30mm,40mm,50mm etc all kinds of norms, which can be chosen according to water quantity, lift height, the gross of solid-liquid separation and  the shape of the separation material and particle size , the material quality of  rake tooth can be ABS engineering plastic、nylon、stainless according to user’s request. Main body frame have stainless material and Carbon steel antiseptic.
