HPGE bar screen for sewage filtration is a widely used and highly recognized dirt pretreated and blocked equipment in the wastewater treatment. It can be applied for municipal sewage, drainage pumping plant, urban wastewater, industry wastewater, etc.
It consists of transmission device, rake chain system, supporting frame and screenings removal mechanism.
Main machine frame is welded to special assembly platform according to the JB/ZQ4000.3-86 General technical conditions for welding parts. Tooth is made of quality stainless steel or nylon and is formed through primary stamping by using mound and punching machine. Tooth rake is a large rotational plane composed of many small tooth rakes. Nylon shall be used as isolation pad to ensure spacing between teeth.
This mechanical rotary fine bar screen is an overall net composed of several small teeth. Under the driving by chain, it does screen work from bottom to top. It discharges dregs by means o self-weight of screening and removal device.

Brief introduction

The Chain Driven Bar Screens are the mostly preferred screening equipment for removal of solids sizing in a wide range. They are specially designed for installation as coarse and fine screens for medium and large sized water and wastewater treatment plants. Chain Driven Bar Screen “AME” is mainly consisting of bar screens, frame, dead plate and discharge chute which is equipped with a ladle rake and a counter cleaning mechanism

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

Woking Principle:

The bar screens are cleaned by the help of a ladle rake which is connected to an endless chain operating between two sprockets. The ladle rake is lowered down to the bottom of the channel in open position. It is closed at the bottom to clean the debris which is settled on the screen bars and moves up. The collected debris in the ladle rake is cleaned by a counter wiper when the ladle rake reaches to discharge point. Here the screenings are either removed to a container or a transporter for further processing.
