RRS Rotary Rake Screen

1 .Application
    RRS Rotary Screen (Also called as rotary solid-liquid separator),is an advancedsolid-liquid separa on device which has been wi-dely used in municipal wastewater treatment plant, pre-treatment device for domesc effuents, municipal rainwater & sewage pump sta-on,water intake of water supply plant & cooling water of power plant. It can also be used for industrial wastewatertreatment, such as tex-le, prinng and dyeing, food, fisheries, paper making, brewing, slaughtering and tanning industry. It is regarded as the ideal solid-liquid s-eparaon equipment in water treatment field.

2 Structure& Working Principle
    The rotary screen is installed at the inlet of pump staon or water treat-ment system. It is composed of pedestal, specific plough shaped nes,rake plate, elevator chain and motor reducer units etc. It is assembled into diffe-rent spacing according to different flow rate.The rake plate ,which is fixed in the elevator chain,starts clockwise movement under the drive of the driving device, hooking residue from down to up together with the elevator chain.
    Under the effect of steering guide and guiding wheel, residue gets discharg-ed by gravity while the rake plate reached the top of screen. The rake nesmoved to the boom of the equipment and starts to work for another roun-d,residue moves connuously.
