What Are the Different Types of Mechanical Bar Screens Available?

2024-10-09

Mechanical Bar Screen is a type of equipment that is used in wastewater treatment plants and pumping stations. Its function is to intercept debris, such as plastics, rags, and other solid waste, to prevent damage to downstream pumps or other equipment. Mechanical Bar Screens are classified broadly into four categories. They are Climbing Trash Rakes, Chain Rakes, Multi-Rake Screens, and Coarse Screens.

What are Climbing Trash Rakes?

Climbing Trash Rakes consists of a set of rakes, which are mounted on a carriage and attached to a guide rail. They are used in deep channels, wastewater treatment plants, and other applications with high water flows, where there is a risk of flooding.

What are Chain Rakes?

Chain Rakes consist of a chain, which continuously runs over two sprockets, fitted at the bottom of the bar screen. A number of rake teeth are attached to the chain. These teeth move along the entire length of the screen removing debris and dumping it into a conveyor. It is often used in pumping stations.

What are Multi-Rake Screens?

Multi-Rake Screens are usually constructed of several parallel bars that are arranged horizontally. Each of them has a rake that moves perpendicular to them and removes debris. Multi-Rake Screens are commonly used in wastewater treatment plants.

What are Coarse Screens?

Coarse Screens are composed of large, perpendicular bars, at equal distances apart. It is used to remove large objects, such as tree branches and rocks that could damage pumps, catch certain types of solid waste, and protect downstream equipment. In summary, Mechanical Bar Screens are an essential piece of equipment in treating wastewater. The type of Mechanical Bar Screen used depends on the location and type of debris they need to intercept.
