Description
Technical field
The utility model is related to plastic granulator technical fields, more specifically, it relates to a kind of underwater pelletizer.
Background technology
The operation principle of traditional waste plastics recovery extruding granulator is by single-step form or two steps type extruder, by plastics
Melt filteration, squeezes out tie rod, then the pelletizing after cooling and solidifying, and underwater cutpellet extruding granulator is without tie rod or cannot to draw
Under conditions of item, a kind of directly novel mechanical of pelletizing, melt pelletizing are contacted simultaneously with cooling water in the moment of melt extrusion die face
Opposite solid-state pelletizing has apparent advantage.Since plastics are scraped by blade under melt state, solidified after circulating water
, this granulating form can be used in the high polymer of different viscosities, and pelletizing will not form any dust under melt state, and cut
Particle shape shape is regular, and packaging, transport are more convenient；The load and pelletizing speed of die head are adjusted according to extrusion capacity Auto-matching,
Change the size of pelletizing, can also manually using different blade numbers when knife rest change pelletizing size and shape；Pelletizing,
Cooling combine together eliminates the cold rinse bank of 4-6mm long, greatly reduces floor space；Prilling realizes automation, operation
Conveniently, noise is relatively low, chipping qualities is good.With the yield than traditional tie rod pelletizing bigger, lower energy consumption.Underwater cutpellet is granulated
Unit generally comprises single-step form or two rank vented extruders, underwater pelletizer, flexible tool apron, automatic dewatering unit, vibration point
From sieve, blast system, gather materials hopper, control system composition.When uniform high-temperature fusion shape material enters from upstream equipment end
Die head runner, material are cut into drop by high-speed rotating pelletizing machine knife blade when just leaving die orifice and enter processing water
In, since the maximized physical characteristic of particle specific surface area and the drop-wise polymer of fusing are the same as the temperature difference of processing water, drop
It solidifies and forms the particle close to sphere.The granulation mode of this " somewhere between fervent and cold cut critical condition " determines that it can
Competent molten state intensity difference well, viscosity is big, the material granulation operation high to heat sensitivity.
Authorization Notice No. is that the Chinese patent of 206445980 U of CN discloses a kind of improvement underwater cutpellet dehydrating integrated machine,
Including main platform, pelleter, centrifugal dehydrator and cyclic water tank, the centrifugal dehydrator is installed by a dewaterer support
In described main platform one end, the cyclic water tank is arranged in dewaterer support side, the water outlet of the centrifugal dehydrator

Cabinet is arranged in the platform support side；The cooling cycle water pipe is respectively communicated with the cyclic water tank, the centrifugal dehydrator
Feed inlet.
By the way that centrifugal dehydrator and pelleter are arranged on same main platform, and form cooling water circulation structure, energy
Enough efficient utilizations to cooling water；But according to specification and Figure of description it is found that the plastic grain of production passes through cooling
Circulating water pipe is delivered directly at cyclic water tank, then is delivered to the plastic grain in cyclic water tank by cooling cycle water pipe
It being carried out dehydrating at centrifugal dehydrator, circulating water pipe blocks in order to prevent, and conveying is all continual quick progress, and
The water temperature of circulating water pipe cannot be too low according to equipment need of work so that has cooled down and has been hardened outside plastic grain, but inside is also
It is completely not cooling, and uncooled plastic grain is easy to be deformed during collecting stacking pressure, leads to the matter of product
Amount declines, and can only increase cooling water pipe to increase the cooling effect of plastic grain, causes the floor space of equipment to increase, no
Easily put.
