Bar Screen Assemblies are used in an open channel (free surface) flow applications to separate & detain course debris and contraband. These unusual solids have a potential for “clogging” the public sewer line, causing expensive cleaning and downtime of the sewer system. Bar Screens can be used for sanitary or stormwater applications. As opposed to expensive automatic rake screens, bar screens are more economical but require manual cleaning. Bar screens are ideal for facilities which have a full maintenance staff. The bar screen is designed for ease of maintenance while maximizing safety. The Bar Screen consists of a structural concrete vault assembly with a preformed channel. The channel is placed at the flowline elevation of the inlet and outlet sewer pipe connections (typically at 3’ to 8’ below grade). Within the channel, vertical stainless steel screens are positioned at an inclined angle. Screen openings are typically ½” to 2”. Often, multiple screens are used with progressively smaller screen openings.

                   

YMGS Mechanical Bar Screen has the below advantages:

• High Automaticity-can work continuously without any operation         
• High Separative Effiency
• Low Power Consumption
• No Noise
• Good Corrosion Resistance
• Self-Protection---when overload,it will give sound-light alarm and stop working automatically
• Can work based on different setting
• Self Control and Manual Control
• Self Cleaning

The Mechanical Bar Screen is composed of driven device,rake tooth facility,flush facility,which is assembled by a special rake tooth into a group of rotary grille chain.

Under the drive of motor reducer,the rake tooth chain turn Rotary motion as reverse flow.When it get the top,the guiding power of the geneva wheel and curve will make every rake tooth to do the relative self-cleaning motion,then due to the gravity,most of the solid will drop down. The sundries sticking in the rake tooth will be cleaned up by sweeper's reverse movement.

• The depth of Ditch will be customized as the buyer's requirement.
• Diversion trench Length(mm)=1500+Hxctga
• Medium maxi temperature(°C)=less than 80 degree
• foot margin to discharging top mouth height H(mm)=400~1000m

The mechanial bar screen need the below Accessories
