Mechanical Bar Screen For Wastewater Treatment
Mechanical bar screen is an advanced solid-liquid separation unit.
It is mainly applied for municipal, district WWTP pre-treatment
stage, municipal rainwater and sewage pumping station, waterworks and cooling water from power plant. This unit has been
widely applied in textile, printing and dyeing, food, aquatic
product, paper-making, slaughter, tannery wastewater treatment
process. It is an ideal unit for screening.
How it works?
This unit adopts rotary type, several plow-shaped rake will be
installed on the shaft,forming rake chains. According to the water
flow volume, the bar screen will have different spaces or gaps installed on the front of the
pump station or water treatment system. When the drive mechanism move from bottom to top with rake
chains. The debris will be taken out from the rake chains, while
the liquid will flow through screen gap. When the unit rotates into
the top, the rake chain will revert its running direction, moving
from top to bottom. The matters will fall off from the rake chains.
When the rake rotates into the bottom from the opposite side. Then
it will re-start for continuous running.
Denor mechanical bar screen benefits
High degree of automation.
High efficiency of separation.
Quick install – shipped fully assembled and ready to operate.
Low energy consumption, no noise, outstanding corrosion resistance.
Continuous and stable running without guard.
With mechanic over-load safe protection. When it occurs fault, cut
off the shear pin in case of overloading working and damaging the
accessories.
We can adjust the running interval according to the clients'
requirement reaching periodic operation. We can have control the
unit automatically according to the liquid level difference before
and after the screen. Also, the manual control can help us for
maintenance. We can select the control mode according to the
client's requirements.
Easy maintenance: because of its reliable design, it has strong
self-cleaning ability during working and operation with no blocking
phenomena.
