Description

Rotary Rake Screen (Also called as rotary solid-liquid separator), is an advanced solid-liquid separation device which has been widely used in municipal wastewater treatment plant,pre-treatment device for domestic effluents, municipal rainwater & sewage pump station,water intake of water supply plant & cooling water of power plant. It can also be used for industrial waste water treatment, such as textile, printing and dyeing, food, fisheries, paper making, brewing, slaughtering and tanning industry. It is regarded as the ideal solid-liquid separation equipment in water treatment field.

Structure& Working Principle

The rotary screen is installed at the inlet of pump station or water treatment system. It is composed of pedestal, specific plough shaped tines, rake plate, elevator chain and motor reducer units etc. It is assembled into different 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 discharged by gravity while the rake plate reached the top of screen. The rake tines moved to the bottom of the equipment and starts to work for another round, residue moves continuously.

Applications

· domestic effluents

· municipal rainwater

· sewage pump station

· water intake of water supply plant

· cooling water of power plant

· industrial waste water treatment (textile, printing and dyeing, food, fisheries, paper making, brewing, slaughtering and tanning industry)

Technical parameters

Advantages

· The driving device is under the drive of cycloidal pin gear speed reducer or helical gear reducer, with low noise, neat structure & stable operation.

· Integrated framework, with good rigidity and convenient installation and maintenance.

· Different spacing of for coarse screens and fine screens.

· Easy to operate. It can be direct or remote controlled.

· Mechanical shearing bolt & over-current protection are set to ensure safe running.

· While the width of equipment over 1500mm, parallel machines are adopted to ensure the integrated strength of equipment.
