Mechanical rake screens are installed in buildings, at sewage and waste water treatment facilities. These devices are renowned for their simplicity in operation, durability and reliability.
PURPOSE AND ADVANTAGES OF SCREENS
This machine is designed to remove large and medium-sized debris from domestic and industrial wastewater. The debris is then mechanically loaded into a waste container or discharged onto a conveyor.
Mechanical rake screen is a movable mesh filtering element that removes large sized debris from liquids. It has a self-cleaning function, which avoids machine downtime during operations at waste water treatment lines at the enterprise.
Rake screens have the following features:
- Resistance to corrosion. All components are made of high-quality stainless steel or plastic (chain bushings, teeth), which work very well in wet environment.
- Successfully used in polymer waste processing lines. Screen equipment is installed in municipal or industrial waste water treatment plants. Additionally, higher levels are installed for waste discharge.
- Holding up different sized solid contaminations. Thanks to the translational movement, the mechanized rake screen accumulates large and medium sized debris, and then raises them to the discharge point.
The operating principle is simple: debris in the liquid is trapped by the screen. The rake collects debris from the top edge of the frame. On the slope, the ejector moves the debris into a special container. The frequency of operation depends on the machine settings.
