Mechanical Bar Screen decontamination machine is a kind of
continuous automatic interception and removal of various shapes of
debris in the fluid, an automatic bar screen wastewater treatment
equipment , mainly used in urban sewage treatment plants, municipal
sewage pipe channels, water plants and power plant cooling water
and other water inlets for debris separation. Also, can be used for
textile, fruit , aquatic products, papermaking, winemaking,
slaughtering, tanning and other industries in the production
process for washing or pretreatment screening. It is an ideal
solid-liquid screening equipment .
Mechanical bar screen is a critical component in wastewater
treatment systems, designed to remove coarse solids and debris
during the preliminary treatment stage. It operates by utilizing a
series of vertically or inclined metal bars spaced at specific
intervals, which are mechanically raked to intercept and lift large
particles such as plastics, rags, and organic matter from influent
streams. This equipment is widely employed in bar screen
wastewater treatment processes to protect downstream pumps and
processes from clogging or damage.
Mechanical Bar Screen Structure Principle
Mechanical Bar Screen decontamination machine is made of ABS
engineering plastic, nylon or stainless steel special type rake
teeth, in a certain order of arrangement installed on the rake
shaft to form a closed rake chain. The lower part of which is
installed in the inlet water, when the transmission system drives
the sprocket for uniform speed directional rotation, the entire
rake chain will move from top to bottom, and carry solid debris
separated from the liquid, the fluid flows out through the rake
gap, the entire working state is continuous.
