Product Description: Structural principle and
application analysis of FLNJ inner inlet mesh plate fine grid and
drum grid inner inlet mesh plate screen application FLNJ inner
inlet mesh plate fine grid is suitable for solid-liquid separation
process and can be widely used in municipal sewage, such as
pretreatment process and advanced treatment process of new,
reconstructed, water quality upgrading, technical transformation
and updated sewage treatment plant; Structural principle and
application analysis of fine screen of inlet mesh plate in
industrial FLNJ and inlet mesh plate grid in drum grid. purpose
FLNJ internal inlet mesh plate fine screen is
suitable for solid-liquid separation process, and can be widely
used in municipal sewage, such as pretreatment process and advanced
treatment process of reclaimed water in new construction,
transformation, water quality upgrading, technical transformation
and upgrading sewage treatment plants; Industrial wastewater such
as textile, papermaking and other processes and Laishui
pretreatment process. Structural principle
FLNJ self inlet mesh plate fine screen is composed of
six parts: self frame, driving system, mesh plate system,
backwashing system, slag removal system and electric control
system. The reduction motor drives
the sprocket to rotate, and the sprocket drives the mesh plate to
rotate continuously; The sewage enters the screen from the water
inlet and is filtered by the mesh plate. After filtration, the
water flows to the outside of the mesh plate. The sewage is
intercepted on the inner surface of the same plate and brought to
the top with the continuous rotation of the mesh plate; The
backwashing system washes the outside of the washing plate. Under
the action of washing water, the dirt is washed to the slag
receiving tank and flows out of the sewage outlet together with the
washing water. 1. Rack part The main material is
304. 2. driving system The drive sprocket adopts
PA1010, which has excellent wear resistance and self lubrication,
good rigidity, mechanical strength and medium stability. Its
acid-base resistance, oil resistance and cold resistance are very
good, ensuring its use in sewage environment. The guide rail is
made of high molecular polyethylene, which has good wear resistance
and self lubrication. 3. Screen system The inner
sleeve of the rotary wheel is a nylon injection molded part, and
the outer sleeve adopts glue hanging treatment to improve the wear
resistance. Since the glue layer has good elasticity. It prolongs
its service life and protects the surface of the guide rail at the
same time. The chain plate is a polyethylene
injection molded part with unique structural design. It can well
seal with the end face of the guide rail during the rotation of the
screen plate, so as to prevent dirt from entering the guide rail,
resulting in filtered water pollution and wear of the guide rail.
The mesh plate is the core component of the whole
mesh grid. It adopts non-metallic injection molding parts to reduce
the weight of the whole machine. At the same time, the modular
design is conducive to the installation and maintenance of the mesh
plate system. Performance characteristics 1. High removal rate,
which can effectively remove hair and other fibrous substances; 2.
The backwashing water will completely remove the dirt trapped on
the screen plate and will not fall into the filtered water to avoid
secondary pollution; 3. The mesh plate adopts non-metallic
injection molding parts, which are wear-resistant and
corrosion-resistant; 4. Underwater transmission parts are not set,
so there is no need for maintenance, which is more convenient for
overhaul and maintenance; 5. Easily worn parts are fully
standardized, easy to replace and easy to operate; 6. Stable
operation, light vibration and low noise. technical parameter 1.
