Description
Technical field
The present invention proposes a kind of hot regenerated integrating device of waste rubber that is suitable for, the category that belongs to the regeneration processing of waste rubber heat and utilize.
Background technology
Be the epoch of emphasizing recycling economy and Sustainable development now, the regeneration of waste rubber, it should be this rubber sources poorness of China, the country that environmental pollution is serious, put into practice recycling economy and Sustainable development, carry out economic construction and revival of nationhood the sunshine industry that must put forth effort to develop on a large scale, but owing to develop to such an extent that is that all right is ripe to the regeneration techniques of the scrap tire rubber of super waste rubber total amount 60%, particularly to using damaged tire through fragmentation, separate, the technology of Processing of Preparation regenerated rubbers such as the disconnected sulphur of high temperature, promptly so-called " heat regeneration " technological development must be also not enough, cause industry seventy percent the enterprise of being out of the line with damaged tire preparation, regeneration rubber in China, be in meagre profit economically for a long time, do not have sharp, the sexual valence of product, property this than etc. the rare progress of intension, production poisoning dirt is big, pollution is many, and product current consumption descends and lacks the situation of art.Referring again to the ups and downs track of developed countries regenerated rubber industry, is that the industry with damaged tire preparation, regeneration rubber also can go on foot external dust kicked up by somebody walking in front, becomes the twilight industry of development prospect dimness.
Damaged tire is through traditional fragmentation, separate, the high temperature sulphur that breaks, the normal temperature refining, or through up-to-date fragmentation, separate, high temperature livering or the so-called hot regeneration techniques processing of in the cream slurry, admixing ordinary carbon black again, though still there is the utilization of contaminatedization of nylon fiber skeleton low value, tenderizer toxin harm environment, serious technologies such as sizing material regeneration back rerum natura return rate is low, product defects, but sizing material with this hot regeneration techniques processing, because of rubber hydrocarbon chain warp elevated temperature heat and the essence of crossing the roller shearing force field are plasticated, or be swelled into the cream slurry through the heavy dose of hot solvent of high temperature, the rubber hydrocarbon chain mostly is recovered to wire, the goods sizing material that causes regenerated rubber or be furnished with regenerated rubber has higher elongation, this sizing material rerum natura is that to attempt to substitute being commonly called as of the normal temperature of thermal reclamation rubber or low-temperature freezing gained meticulous, ultra-fine rubber powder is not available, also be recent listing newly developed only through high temperature or normal temperature plastics processing, but it is not do not have, or not available through excess dosage solvent High-Temperature Strengthening swollen plasticizing rubber powder through roller shearing field.So thermal reclamation rubber is popular in the big downstream user of product elongation numerous emphasizing.In view of this as long as the hot regeneration techniques of waste rubber is through the innovation improvement, make it meet the pervasive index of Sustainable development, i.e. the hot regeneration techniques of waste rubber to comprising damaged tire, make it meet the formula resource circulation utilization requirement that develops simultaneously of four flags that " value, energy-conservation in full, green, high " change, just can realize making the thermal reclamation industry of waste rubber to be reborn.
System proposes damaged tire is implemented the develop simultaneously document of formula resource circulation utilization scheme of four flags that " value, energy-conservation in full, green, high " change, first elects Chinese patent application (200810083330.6).This scheme adopts and will have now comprising that the various of waste rubber product such as damaged tire utilize the combination of technology to implement, and makes regeneration process independent separately originally and that competition is implemented, becomes proportional collaborative implementation process.This damaged tire regeneration scheme, the polyamide skeleton fiber of regeneration low value not, no longer include a low value thermo-cracking sooty outlet difficult problem, the high value product of gained comprises: steel wire, damaged tire thermo-cracking oil fuel or its fractionation oil product, the 100 order powder of scrap tire rubber and the carbon black stock of damaged tire thermo-cracking are so-called ultra-fine rubber powder masterbatch etc.This scheme with linked together with the process of regular fuel, the hot cracked legal system ordinary carbon black of gas, can process organically combine power consumption process of discharging certain by product and the row who consumes certain by product also the process of utilizing to scrap tire rubber.But this scheme is in the high-valued exploitation of the reconstituted product of scrap tire rubber, be partial to the kind of plasticating without the roller essence, hot regenerative process itself to waste rubbers such as damaged tire with high elongation rate does not have improvement, and promptly this scheme can't comprise the so-called hot method technology of using now 5～40 mesh sieve rubber powders to prepare regenerated rubber through the disconnected sulphur of high temperature, normal temperature refining procedure.
Up-to-date improvement to hot regenerative process of scrap tire rubber and products thereof has again:
As described in Chinese patent application (200710150962.5), with 20～50 order vulcanized rubber powders, the appointment component tenderizer that adds rubber powder weight 60～115%, put it in withstand voltage heating and stirring tank, through 160～200 ℃, 0.5～0.7Mpa, the hot manipulation of regeneration that was incubated in the jar in 2～3 hours, rubber powder is become the cream pulpous state, admix the carbon black of rubber powder weight 60～100% again, obtain filling sooty paste-like reclaimed rubber product.Carbon black described in this application case only is meant high wear-resistant carbon black or general purpose furnace black carbon black, and used tenderizer (it claims oil fuel) only is meant Stockholm tar or oxidation Yatall MA or coal tar, all is contaminative tenderizer frowzy.This application case is not mentioned the equipment that will use, does not more mention the combined equipment that meets the cleaner production requirement.
And for example Chinese patent application (200710024356.9) is described, with the tire glue powder of crossing 40 mesh sieves, the appointment component tenderizer that adds rubber powder weight 21～30%, put it in withstand voltage heating and stirring tank, through 240～260 ℃, 2.6～3.0MPa, be less than the hot manipulation of regeneration that was incubated in the jar in 1 hour, to go out the rubber powder that is loose cake shape after jar is lowered the temperature and plasticate, obtain the high strength regenerated rubber product of tensile strength at yield at 12～18MPa through the roller essence.The used tenderizer that reaches only is to comprise solid coal tar in this application case, and this is a kind of contaminative tenderizer of foul smelling flavor.
And for example Chinese patent application (200710192039.8) is described, with the tire glue powder of crossing 20 mesh sieves, the appointment component tenderizer that adds rubber powder weight 20.54～25.1%, put it in withstand voltage heating and stirring tank, through vapor pressure 0.6～1.0MPa, the hot manipulation of regeneration that was incubated in the jar in 20～40 minutes, to go out the rubber powder that is loose cake shape after jar is lowered the temperature and plasticate, obtain the high strength regenerated rubber product of tensile strength at yield at 15～16MPa through the roller essence.The used tenderizer that reaches only is to comprise Yatall MA, coal-tar pitch etc. in this application case, all is contaminative tenderizer frowzy.
Chinese patent application (200810146444.0) is described for another example, is a kind of instant activation reduction method for rubber, it is characterized in that: a, adjustable pressure cabin adapt to the rubber powder of various particle diameters; B, small one and large one forms shearing force to revolving screw rod under anhydrous state; C, friction generate high temperature moment and shear action voluntarily; D, seal cavity water cooling; E, S auxiliary agent quicken hot oxygen and separate collecting process, and protection is not by Pintsch process.In this application case, the heat that sizing material is suffered, be that the friction that comes from by driven by motor generates, it must be greater than fuel direct heating or UTILIZATION OF VESIDUAL HEAT IN heat supply with hot expense, this application case is not to be higher than the product of GB to make clear and definite detailed description to S auxiliary agent and readme in addition, and what provide does not understand revolving the screw rod mechanism synoptic diagram yet, so the extent of disclosure of application case, do not reach those of ordinary skill and need not creative work, just can reappear the stage of this invention effect.
In addition, existing regenerated rubber technology can't be to low gel content or/and the so-called low-grade waste rubber resource of miscellaneous realizes resources truly.
The regenerated rubber product that waste rubbers such as damaged tire obtain through hot manipulation of regeneration, in the rubber item prescription in downstream, use, by " rubber item practical formulation complete works " (Xie Zhonglin, Yang Minfang compiles, Chemical Industry Press, the Materials Science and Engineering publishing centre publishes and distributes, February in 2004 the 2nd edition) listed prescription is added up, can sum up its application characteristic is: have 95% above application examples at least in the prescription in downstream is used, be with the regenerated rubber that meets so-called GB, add new rubber again, strengthening agent, filler, materials such as tenderizer are played glue through eating powder once more.Through this statistical study; can find: existing regenerated rubber production technology; generally do not pay attention to utilizing it to be subjected to the granular of pyroprocessing or cream pasty material to be easy to less energy-consumption and mix the advantage of eating powder; develop to greatest extent and can reduce high power consumption in the time of can making downstream application and eat the regenerated rubber product that powder is played glue; promptly existing regenerated rubber production technology; not comprising can environmental protectionization; make products obtained therefrom in the downstream prescription is used; how to substitute to greatest extent by regenerated rubber and tenderizer; the technical scheme of aggregation that powder auxiliary material is organized, industrial chain is to the regeneration of waste rubber; there is serious excessive repetition processing problems in the Treatment for Reuse.
The hot manipulation of regeneration of waste rubbers such as existing damaged tire, its used combined equipment, because in its hot regeneration and treatment technique of serving, not requiring can be with addition of a large amount of powder auxiliary material that height flies upward contact scar that has, so just be not equipped with airtight feed mechanism, prior art during with addition of material, is all adopting artificial open-sky technique in dynamic jar, material after the pyroprocessing all is to be directly exposed to airborne open discharging, so all exist serious environmental to pollute into and out of material.
