3. Paper Making Flow Chart
Page 3
Through the paper making Flow Chart, we can see that according to the different
effects of the equipment, we divide it into different areas for paper making. They
are divided into Top pulp area, mesh area, press area, front drying, rear press,
rear drying, light press, roll paper area. The spray nozzle used are different in
different area.
Top pulp area: hollow cone defoaming nozzle and narrow angle cleaning nozzle.
Mesh area: Cut-edge water needle nozzle, fan-shaped low-pressure cleaning
nozzle.
Press area: High-pressure needle nozzles, low-pressure fan-shaped nozzles,
wide-angle lubrication nozzles, high-pressure fan-shaped nozzles.
Front drying area: High-pressure needle nozzles, fan-shaped nozzles, ultra-
high-pressure needle nozzles.
Rear drying area: starch nozzle. Page 3https://www.ccnozzle.com/

Nozzle Introduction：
Can be used for paper edge cutting, with cutting edge precision, clean and
many other features。
A straight needle-shaped fluid column flow can be formed under different
pressure conditions and can withstand pressure up to 140 bar.
Materials Available：Ruby（RBY)、Ceramic（CER)、Tungsten alloy（ALLOY).

The cutting of paper edges
The choice of cut
edge water needle,
general paper
machine aperture
choice is 0.6-1.0,
foreign high-speed
paper machine
selection is 0.4-0.8
double-hole water
needle.
a single-hole usually
is ceramic, and the
double-hole is ruby.

The cutting of paper edges
Moving edge water needles are generally only used when the paper
machine is switched on.
Limit the width of the paper by measuring the performance of different
formulations or paper strength.
Most are driven by compressed air. Page 6

High Pressure Needle Spray Nozzle
General Applications：
High pressure cleaning of long net
Press blanket high pressure cleaning
Blind hole roller cleaning
Groove roller cleaning
Dry net shutdown cleaning

High Pressure Needle Spray Nozzle
Generally, high-pressure
nozzles are installed on the
spray rod, according to the
different spray rod installed
nozzles also have a difference.
Installation threaded
connection without bristles,
mounting sheet-shaped needle
nozzle with bristles.
The spray rod is also divided
into drive and non-drive. The
drive is also divided into
pneumatic, electric and water-
moving.

Spray rod drive
The drive of the spray rod is currently
used: pneumatic, water-driven, electric.
Pneumatic: use compressed
air to push the operation of
the cylinder to control the
repeated movement of the
spray rod, the advantage is
that the operation failure is
less.
Water driven: through
pressure water to drive
the piston's round-trip
movement, there is a
special conversion
block, the advantages
of cheap affordable can
withstand the
environment.
Motor drive: mainly through
the operation of the motor to
drive the shuttle movement of
the spray rod, the advantage
of the motor is that the PLC
can adjust the stroke, in the
choice of control performance
more than the other two.

Advantage of Spray Rod with brush
With brush shower rods are divided into: manual
brush and automatic cleaning.
Manually cleaned shower rods can also manually
rotate the stainless steel brush inside the shower
rod when it is down or not, cleaning the debris
stored inside the shower ingress tube and
opening the sewage valve to remove impurities.
The automatic spray bar is driven by a motor to
control the cleaning interval and automatically
open the solenoid valve through the system for
discharge.
Regular cleaning of the spray rod can improve
the service life of the nozzle, but also can prevent
the nozzle is blocked after the timely detection
and so that the blanket or mesh cloth did not
clean in a timely manner dirt caused by bad
paper.
It can extend the life of blankets to reduce the
production of sick paper.

12. 压榨部
Pressing section is the paper equipment installation of the largest area of spray
rod, there is high-pressure cleaning spray rod, there is low-pressure cleaning
spray rod, there is a wet slip spray rod. Different apertures are selected according
to the vehicle speed of the different paper machines.
The nozzle spacing on the spray tube is generally 75MM to 120MM. Now more
than 4 meters of paper machine a lot of a spray rod has about 50 nozzles.
The press section requires at least 15 with the spray rod.

13. Starch spraying is mainly in the paper forming time re-pulping after the
addition of diluted starch solution, according to the actual situation of the
customer concentration in the range of 1.5%-5%. Used to improve the
performance of paper.
Starch spraying has a condition where it is easy to plug the nozzle nozzle
and needs regular maintenance. The selection of nozzles is determined
according to the customer's injection volume and the width of the paper.
Nozzle material: 316SS and ceramic panels

14. 扇形喷嘴
Fan-shaped nozzles are common in the paper industry and have
many main uses: low-pressure cleaning, scraper lubrication,
spraying of calcium powder, starch spraying, peeling spray,
wetting spray before start-up blankets, mesh cleaning.
Nozzles Materials: PP plus metal mosaic, metal plus ceramic
mosaic, pure metal (316SS)
Appearance: ordinary thread fan, disc fan, plastic quick lying
Traffic floating: from 11001 to 6540/6550.

15. 窄角扇形喷嘴
Narrow-angle fan-shaped nozzles, V-type narrow-angle nozzles are
characterized by narrow-angle fan sprays that produce high impact forces. The
spray produces a medium distribution of the droplets in medium size. And its
boundaries are clear. Suitable for stable paper frames and cleaning on paper
machines.
At the same time in the pulping is a very good peeling nozzle.
A narrow-angle nozzle with backflushing reversereverses its valve after the
injection hole is blocked by a foreign body, allowing the foreign body to squirt
out from the punching side. It can be maintained online without removing the
nozzle for easier use. Page 15

17. Air Atomzing Nozzle
A dual fluid atomizing nozzle is a mixture of liquid and gas that sprays out
through the nozzle head. The mist droplets produced by its spray effect are
very small and suitable for spraying chemicals in paper processing.
Characterized by a small distribution of spray.
At the same time in the paper machine's subsequent processing can also be
used in the local humidification, de-static electricity.
