Description
Technical field
The invention belongs to waste old circular regeneration fields, and in particular to a kind of using multistage extruder desulfurization production regeneration
The method of glue.
Background technology
In waste old circular regeneration field, waste old is mainly broken into rubber powder and is made again by desulfurization process
Raw rubber is recycled.There are many kinds of the methods of desulfurization, wherein more advanced using screw extruder sulfur method, by rubber powder and
Regenerative agent, which is uniformly mixed, is sent into extruder, de- by being completed under the action of the Strong shear of a period of time of screw rod, extruding and heating
Reclaimed rubber is made in sulphuring treatment.The method is continuous production, and production efficiency is high, and pollution is small, low energy consumption, good quality of product.But by
Long in screw rod, extruder abrasion is larger, more demanding to equipment quality.
Screw extruder sulfur method primary structure is two kinds of single-screw machine and double screw extruder at present.Wherein twin-screw
Extruder is due to region of engagement gap very little, therefore the directional velocity of engagement place screw thread and screw channel is on the contrary, have very high shearing speed
Degree and pressure, have preferable self-cleaning action, can scrape off the most of buildup being adhered on screw rod, sizing material desulfurization effect is preferable.
But double screw extruder is complicated, and requirement on machining accuracy is higher due to region of engagement gap very little, waste old such as tire, voluntarily
Contain steel wire in tire, adhesive tape, although these waste olds have been subjected to magnetic screening in broken pulverizing process, still some small steel wires
Head, handstone etc. enter extruder, and the abrasion of the screw rod, machine barrel of extruder is caused even screw deadlocking phenomenon occur.Single screw rod
Extruder structure is simple, and failure rate is low, but single screw rod shear ability is low, to reach Strong shear speed and pressure and good desulfurization
Effect need to increase the length of screw rod, and after spiro rod length is extraordinary, the manufacture difficulty of screw rod can significantly increase.Simultaneously because rubber powder
Plasticity is easy to be adhered in screw channel, and sizing material can not effectively be conveyed by resulting even in screw rod, and production terminates.Long spiral shell
Bar also is difficult to clean.How spiro rod length is shortened, and it is problem to be solved that can reach desulfurization effect.
Invention content
Technical problem solved by the invention is to provide one kind based on screw extruder, and long screw rod is become multistage
Short screw extruder, the head of the extruder of previous stage are connected to the entrance of next stage extruder, flange are used between every grade
Connection is convenient for the conveying of sizing material, every grade of screw extruder to be equipped with independent motor driver and temperature control system, make sizing material
It is sheared in multistage extruder, squeezes and reaches good desulfurization effect under thermogenic action.To obtain qualified reclaimed rubber production
Product.
The technical solution adopted in the present invention is：A kind of to be horizontally mounted more screw extruders, each extruder is in people
Font, Left Drive extruder replace stacking with right transmission extruder, and more extruders can be arranged according to design.One extruder is
Level-one, first order extruder discharging mouth squeeze out machine inlet usage orchid with the second level and connect, and form the closed conveying of sizing material, glue
Powder enters extruder by the feed inlet of previous stage extruder and squeezes charging of the heated transportation to next stage extruder through screw rod shearing
Mouthful, sizing material is heated in next stage extruder by the further shear extrusion of screw rod, until completing waste old rubber powder desulfurization process.
The series needed for extruder is determined according to the desulfurization effect of sizing material, can be pacified with 1,2,3,4 to N connection type along equipment center line
Extruder needed for dress is more unlimited, to reach good desulfurization effect.It is characterized in that：
1. the screw rod of every extruder need not be very long.Screw rod processing and manufacturing is simple, cleans, repair, and it is convenient to replace.
It, can be in glue 2. every extruder has independent motor, speed reducer, screw rod, machine barrel, temperature control system, sliding rail
Different temperature and pressures is controlled in the sweetening process of material, reaches good desulfurization effect.
3. simultaneously for convenience of gel resin and the plant maintenance of screw rod and connecting flange, extruder barrel fuselage is mounted on sliding rail
On 5, fuselage is moved along sizing material advance negative direction, to eject screw rod, cleans connecting flange.
The invention has the advantages that under the premise of plurality of advantages of the holding with screw extruder continuous desulfurization, solve
Double screw extruder is complicated, equipment high precision machining and single screw extrusion machine shear ability are low, the processing of overlength screw rod difficulty, clearly
The problem of glue difficulty.
Description of the drawings
Attached drawing is schematic diagram of the present invention.
Specific embodiment
According to schematic diagram of the present invention, more extruders are along equipment center line with 1,2,3,4 to N connection type, level peace
Dress, in chevron shaped, Left Drive extruder replaces stacking with right transmission extruder for each extruder, sizing material by first order extruder into
Enter, next stage is delivered to along diagram sizing material direction of advance, to reach good desulfurization effect.The number of units of extruder can be arbitrary
It is more, specifically determined by the desulfurization effect of sizing material.Extruder has sliding rail, extruder barrel fuselage is mounted on sliding rail 5, by fuselage
It is moved along sizing material advance negative direction, to eject screw rod, cleaning connection flange.
Claims (3)
1. a kind of method using multistage extruder desulfurization production reclaimed rubber, which is characterized in that one kind is using screw extruder as base
Long screw rod is become multistage short screw extruder by plinth.More screw extruders are horizontally mounted, each extruder is in herringbone
Type, Left Drive extruder replace stacking with right transmission extruder, the series connection of unlimited amount extruder may be implemented.One extruder
