Description
Technical field
The utility model relates to the qualitative device of a kind of cooling, particularly a kind of regeneration cooling qualitative device for changing waste rubber into resources.
Background technology
Rubber sources utilizes the development of industry again, in China's T﹠B.Because the special rerum natura of rubber, caused it can not be as the simple recycling of plastics.Through sulfurized rubber, change has taken place in molecular structure, become the network-like molecular structure of 3 D stereo from the extremely strong linear molecule chain structure of plasticity-, for example tire, rubber overshoes etc. but have brought trouble also for simultaneously the utilization again of its waste product to its requirements such as intensity to have satisfied rubber item.To utilize the rubber after the sulfuration again, just need to recover its plasticity-through special technology and equipment.All the time, this rubber that has recovered plasticity-, can utilize again is called as reclaimed rubber, and this is a kind of address of imagery, and in fact its performance can not return to natural rubber or elastomeric performance level far away.
Over past ten years, because the consciousness of whole society's resources conservation and recycle is more and more stronger, rubber sources recycle industry has also obtained significant progress, and new technology emerges in an endless stream, new equipment continues to bring out, and reclaimed rubber output rises year by year.Even to this day, the reclaimed rubber output of China has occupied the No. 1 in the world, and the state of the art of related process and equipment also occupies prostatitis, the world.
Utilize the development of industry again along with vulcanized rubber, the performance of reclaimed rubber also approaches the technical feature of former untreated rubber from becoming not as good as primary rubber far away, this performance more and more approaches former untreated rubber " regeneration " glue, every performance index reach 80～90% of former untreated rubber, on the degree of maximum, restored the performance of former untreated rubber, so also be called recovery glue by rubber sources recycle industry.
Present various popular regeneration process of waste rubber substantially all is under specific high temperature and pressure, cooperates specific auxiliary agent, disconnects containing the S macromolecular chain in the vulcanized rubber, recovers the performance before its sulfuration.Its chain rupture device, what generally use at present is digester, and the equipment such as Banbury mixer of adopting are also arranged, these device common characteristic are, they can provide needed high temperature of reaction and pressure, but after reaction was finished, they can't reduce temperature fast with stable regeneration/recovery colloidality energy.The manufacturing enterprise that has in the actual production adopts out the method that paves behind the jar to reduce reacted rubber powder temperature, but this method need consume a large amount of time and artificial, and the high temperature rubber powder is exposed in the air incipient scorch reaction can take place, and influences quality product, can cause environmental pollution simultaneously.The manufacturing enterprise that has adopts the way that stops in jar to reduce a jar temperature, also need to consume a large amount of time but stop, rubber powder is deposited in a jar interior non-uniform temperature simultaneously, the same quality product that influences, if continuing start when stopping stirs, though can alleviate the uneven temperature problem to a certain extent, consumed a large amount of energy again more, quality product still can not be effectively guaranteed.Also there is similar problem in miscellaneous equipments such as employing Banbury mixer, and problem can not get solving.
Along with the development of rubber recycle industry and the raising of industry technology level, constant product quality and environment protection all there have been higher requirement, above problem is to when pressing for solution.
