Description
Technical field:
The utility model relates generally to a kind of structure of microwave rubber cracking furnace.
Background technology:
Since last century the seventies, states such as France, Japan, the U.S., Sweden, Britain, Italy, Spain, the microwave energy application technology not only has been widely used in the sulfuration preheating of various extruding adhesive tape, sebific duct, and be used for the sulfuration preheating of all kinds of tires, it is the magnetron energy regenerative in parallel of a plurality of 1~5KW of 2450MHz that employed microwave source adopts frequency mostly, and it is 915MHz that the sizing material of big carrying surface is adopted frequency.Microwave generator has good adjusting and control performance, heater can specifically design according to multiple difform sizing material, and travelling-wave type, standing wave type and slow-wave structure etc. are arranged.
China has adopted the microwave vulcanization new technology since reform and opening-up, new technology, and introduced tens microwave seal bar continuous vulcanization production lines from countries such as West Germany, Japan, Spain, Britain, mostly normally come into operation.For further applying, took the lead by the Ministry of Chemical Industry in 1988, units concerned carry out production domesticization work to the state-of-the-art sealing joint strip continuous vulcanization production line that West Germany BESTOFF company introduces.
Along with the development of microwave energy application technology, the producer of some introducing equipment uses producer with microwave energy and cooperates, and has set about the existing problem of vulcanization of rubber equipment of import is transformed, and its product quality and output are greatly improved.Microwave energy is used producer and has also successively been developed some relevant rubber microwave vulcanizing equipments simultaneously, because technology prematurity still at that time, inadequate communication is widelyd popularize always.In recent years, the application of multitube energy regenerative on microwave vulcanization of rubber equipment makes a breakthrough the microwave vulcanization of rubber, also moves to maturity just day by day and perfect.The micro wave regeneration desulfurization of rubber is succeedd abroad.The microwave desulfurization of u s company " Goodyear tire and rubber co " begin one's study butyl rubber, second third glue etc. in 1971, drop into suitability for industrialized production in 1977 and be named microwave desulfurization, obtained United States Patent (USP) in 1978, and again it had been made significant improvement, obtain patent again to the said firm in 1984.Meanwhile, people such as Japanese woods scape three, Yu Tianchun have also delivered the report and the patent of micro wave regeneration rubber desulfurizing method and commercial Application device in Japan.It is reported the industrial applications that microwave rubber regeneration method has been succeedd abroad.

The scrap rubber utilization is that discarded processes such as tire, pipe, band, industrial rubber articles, rubber overshoes and rubber plant's waste material are reclaimed, process and utilize.The recycling of scrap rubber has whole utilization, regeneration and 3 kinds of modes of heat utilization substantially.The whole utilization is that damaged tire is carried out whole utilization, as the processing of the carrying out nerve retreads, fish shelter, water and soil conservation material, fender, construction that make it to recover original purposes are with mud bucket, physical game equipment, road pad, track buffering material, pasture fence etc.Regeneration is that damaged tire is made reclaimed rubber or rubber powder.Heat utilization divides pyrolytic and two classes of directly burning: pyrolytic is with damaged tire hot cracked multiple destructive distillation analytes such as miscella, pyrolysis gas and carbon black that obtain under catalyst action; Directly burning is damaged tire to be acted as a fuel directly be used.
China is a rubber consumption big country.Calendar year 2001 consumes rubber 2,790,000 t altogether, is only second to the U.S. (281.2 ten thousand t), occupies the 2nd in the world.According to IRSG statistics, 2002 China's rubber consumption figure (3,060,000 t) surpass the U.S. (285.4 ten thousand) first, become world's rubber and consume first big country, the U.S. occupies the second, Japan (182.7 ten thousand) the 3rd.In other words, China also will become maximum in the world scrap rubber and produce state when becoming maximum in the world rubber producing country and country of consumption.It is estimated that the scrap rubber composite of the annual generation of China at present is 5,000,000 t nearly.So a large amount of scrap rubber materials is if handle early, not only contaminated environment but also waste resource.
The cracking of damaged tire is reclaimed has become the problem that countries in the world are very paid close attention to.It is under the situation of anoxic or limited oxygen supply fully damaged tire to be heated that the damaged tire vacuum cracking technology of being researched and developed can be ground in Guangzhou, make its high molecular polymer and organic additive be degraded to low molecule or micromolecular compound, make the limonene in the pyrolysis oil of recovery reach 11%.The rubber heat conductivility is poor, and the method for thermal cracking adopts steam or Far-infrared Heating with sizing material and catalyst thereof and since heating-up temperature be by the medium outside to inside heat conduction at leisure, so its heat time heating time is long, efficient is low.
