Mechanical Coarse Bar Screen for Solid and Liquid Separation

A bar screen is a mechanical filter used to remove large objects, such as rags and plastics, from wastewater. It is part of the primary filtration flow and typically is the first, or preliminary, level of filtration, being installed at the influent to a wastewater treatment plant. They typically consist of a series of vertical steel bars spaced between 1 to 3 inches apart.

Bar screens come in many designs. Some employ automatic cleaning mechanisms using electric motors and chains, some must be cleaned manually by means of a heavy rake. Items removed from the influent are collected in dumpsters and disposed of in landfills. As a bar screen collects objects, the water level will rise, and so they must be cleared regularly to prevent overflow.

                   

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

The whole processing is as below:

To protect the equipment in good condition,the paper carton and plastic film will be wrapped outside,as the below picture shows:
