The industrial hi-tech line is intended for processing
strongly polluted PET-bottles in flakes with very high degree of purity. Line
it is developed by the Stankopolimer company especially for work in the Russian
conditions (strong extent of pollution of PET-bottles, inaccurate sorting,
use of rubber glue when gluing labels, etc.)
The stankopet company makes the equipment for processing
polymeric materials enormous experience in this also has more than 15 years
areas.
Basic principles of a design and work of the line
• The industrial line is capable to work 24 hours a day with minimum
operational costs;
• Allows to wash very strongly polluted material to very high
qualities of the final product;
• Surpasses in the indicators and quality of the final product significantly
more expensive lines;
• The modular design, allows to supplement, change an order and an arrangement
cars;
• Due to use of a bathtub of water purification the consumption of water is minimized;
• The line is very reliable, a metalloyemka. All machines are manufactured of thick-walled
metal with use of hard-alloy materials, special training, that
to reduce wear, to reduce to a minimum of costs of repair;
• All parts subject to wear are easily replaced, are simple in production and
installation;
• Includes several steps of a sink, floatation office, rinsing, and
drying;
• The sink without use of chemicals and detergents is possible;
• Uses the basic principles: temperature and friction for achievement
optimum washing effect. The technology allows to achieve two objectives
at the same time, to create necessary degree of friction and to heat water to necessary
temperatures;
• Amount of water, its temperature, friction coefficient, quantity
the arriving material, its time spent in a sink, etc. parameters can
to be changed according to extent of pollution of initial material and
requirements to quality of the final product by means of a control system.

Structure of the line of processing of PET-bottles
1. The table is finishing
On a table finishing bales with raw materials move. Further service personnel
removes a binding from bales, and direct raw materials to an inclined surface of a table, with
which it falls on a proseivatel.
2. Proseivatel
Serves for automatic removal of small foreign particulates (stones,
sand)
3. Sorting conveyor
When passing along the sorting conveyor from raw materials manually
foreign particulates are removed. The conveyor is equipped with a magnetic separator for
offices of metal inclusions.
Serves for giving of raw materials in a zone of loading of a grinder, with an opportunity
adjustments of volume of the loaded raw materials. The electric circuit of the conveyor assumes
opportunity, both continuous work, and work with breaks of established
durations. The conveyor is mounted on wheels with a brake.
Serves for crushing of PET of bottles. When using water in process
crushing noise and speed of a zatupleniye of knives decreases. Besides, the raw materials pass
some kind of primary washing, there is a partial office of dirt, labels and
etc. from PET. The rinsing process following right after crushing washes away all dirt,
separated when crushing. Thus, large number of pollution
it is brought out of system right after crushing. It simplifies further process and
significantly reduces wear of the equipment. The design of a rotor interferes
to excessive heating of a crusher also allows it in a complex with water cooling
bearings to work 24 hours a day. The design of a crusher provides easy
access to the filtering grid and knives of a rotor by forces of one person. For opening
heavy cover the system of rise/lowering is provided.
The centrifuge mechanically deletes the polluting impurity from raw materials with the help
the high-speed rotor supplied with special shovels. Besides
there is an additional separation of dirt from flakes because of their friction about shovels,
rotor and the friend about the friend. Drying of flakes happens due to centrifuge effect.
The external frame is made of carbonaceous steel while all internal parts
- from stainless steel. The rotor and shovels are made of special steel by the person
trainings.
Flakes from the centrifuge by means of pneumotransport get to a separator
labels where there is a separation of easy fraction from PET of flakes. The separated paper
and other impurity get to a separate cyclone the store specially allotted
for this purpose. PET flakes get to a flotation bathtub. Degree of office it is possible
to regulate by means of increase/reduction of a stream of air in a separator.
The frame is made of carbonaceous steel, the special structure is applied on a bathtub with
content of zinc powder, for protection against corrosion.
Polymeric material is entered into a bathtub by means of specialized
the loading screw which disperses the arriving flakes and with a high speed
sprays them under a water surface. It is one of very important constructional
features which provides very high extent of separation of polymers.
The principle of injection also significantly facilitates separation so-called
"crumpled" flakes which turn out as a result of crushing by blunt knives. PET -
flakes fall by a bottom and are transported by the horizontal screw by the end of a bathtub.
There they are picked up by other shnekovy conveyor conducting in the jet washer.
Shredded traffic jams, rings, polyethylene and polypropylene labels and other
the fraction with a specific density has less than unit, emerge and are carried away by water flow
in the special draining section. Water leaves also this section, further easy fractions
are withdrawn by the exhaust screw and get to the separate tank specially allotted
for this purpose.
Water is warmed up at the expense of the electric heaters (TENOV) installed in
to external barrel of a sink. Getting to water, the raw materials begins to fall to a sink bottom,
the voroshitel mixes raw materials with water, and also separates it from alien
inclusions. The raw materials, are unloaded via the unloading screw. Easy fraction (oils, fats,
the label, etc.) separated in the course of a sink accumulates on a water surface and
it is brought out of a sink through a modulation pipe.
Polymeric material is entered into a sink by means of the loading screw. For
successful otmyvka of polymeric materials the sink uses temperature and friction.
The design of the jet washer allows to achieve two objectives at the same time:
to create necessary degree of friction and to heat water to the necessary temperature.
The high-speed rotor separates sticky dirt, glue, paper, etc. impurity
by means of friction. Flakes are in process of friction in the car during
several minutes. At the same time a certain coefficient of friction is supported. In
process time water heats up and reaches temperature of 80-95 degrees that
allows to separate any pollution successfully. In process of material advance
via the machine, pollution are washed and leave together with water.
Amount of water, its temperature, friction coefficient, quantity of arriving
material, its time spent in the car, etc. parameters can be
are changed. This technology allows to achieve magnificent degree of purity of final
product on the one hand and to minimize eksplutatsionny expenses with another.
The car also possesses the exhaust screw for transportation of flakes in
following car.

On a design and the principle of work the car is completely identical with the centrifuge
No. 1, described in point 6.
12. Floatation separator of a label and stopper No. 2
The dirt separated during the first stage of a sink and also the remains of chemical
detergents (if they were used at the previous stage) finally
are washed away by clear water. On a design and the principle of work the car is identical with
the floatation sink No. 1 described in point 8.
13. Centrifuge No. 3
Makes final drying of flakes with use of centrifuge
effect. On a design and the principle of work the car is completely identical with
the centrifuge No. 1 described in point 6.
14. Air separator of labels No. 2
At this stage the remained easy fractions finally separate from PET -
flakes. It is completely identical to the system described in point 7.
15. Cyclone store
Big-Begov serves for filling.
Water purification bathtub
Allows to create the closed system of water supply. Purifies water from
the weighed substances and other, insoluble impurity in water. The vibrosieve separates
firm particles up to 33 micrometers in size, smaller particles separate in a bathtub -
flotator with compartments of the cleaning and filtering substances. Sewage treatment
by flotator it can be carried out with use of various chemical reagents.
The frame is made of carbonaceous steel, the special structure is applied on a bathtub with
content of zinc powder, for protection against corrosion.
