Rotatory mechanical grille of HC,an equipment used to solid-liquid separation can clean out diversified rubbish continuously and automatically.At present,it’s the most advanced technique in our country.
Consisting of drive-machine、dentiform harrows and cleaning setup.Electromotor reducer drives harrow-chain to rotate against the water flow.More rubbishes can drop by the gravitation when dentiform harrows arrive to the top part of the equipment,the rubbishes adhibited on the chain were cleaned out by inverted cleaning setup.
The great virtues are:highly automated,good separability,low power-consuming,no jam and corrosion resistance.Could be operating continuously,the protector of over loading will give an alarm by acousto-optical device,and the elecmotor stopping by itself.
The wide of HG300-1500’s is 1500mm,if the wide is more than 1500mm,may be shunt-wound.The flux,upgrade height,gross of solid-liquid separation and the sharp and size of the rubbish chossing the types,which space between grilles are 1mm,3mm,5mm,10mm,20mm,30mm,40mm,50mm.The materials of harrow are ABS,nylon and stainless steel.Both stainless steel and cast iron that the materials of main body are.
