Abstract
The present invention relates to a quasi-low-temperature crushing technology for a waste and used rubber tyre, which mainly comprises the steps of preselecting, cooling and crushing tread rubber. The technology is characterized in that air enters an air storing tank after being compressed by an air compressor and is filtered by an air filter; the air is dried by an air dryer and is refrigerated by a turbine refrigerator; and the quasi-low-temperature air at the temperature of -5 to-35 DEG C is obtained. The preselected tread rubber is transferred to a feed bin after being cooled by the quasi-low-temperature air; then, the preselected tread rubber is cooled by the quasi-low-temperature air in the feed bin and is crushed by a mechanical crusher. The technology reduces the difficulty of a crushing technology and increases output, and has the advantages of good efficiency and convenient popularization for causing that a waste and used rubber source is rationally reutilized.
Description
The present invention relates to the accurate freeze grinding technology of a kind of waste and used rubber tyre, belong to the waste recovery technology of rubber.
Waste and used rubber tyre all belongs to " rubbish of Hazardous " at home and abroad; the junked tire regular meeting that stack at dry place produces " spontaneous combustion " phenomenon; the easy ponding of junked tire that stack at open-air place; become the breeding ground of bacterium; the use of rubber is very big on the other hand, and especially the application of fine glue powder is very extensive, as: highway, airfield runway, stadiums runway etc. need mix fine glue powder; in the cement of skyscraper, also need mix fine glue powder in the waterproof material, to play shockproof waterproof effect.How correctly to handle junked tire, it is turned waste into wealth, this is the common both at home and abroad problem of paying close attention to.
At present, pollution-free pulverizing has two kinds of technical methods to waste and used rubber tyre both at home and abroad, that is: 1. normal temperature mechanical crushing method, 2. low temperature (about 120 ℃) mechanical crushing method, two kinds of breaking methods all have its weak point, 1. normal temperature mechanical crushing method wherein, can produce high heat in the process of micelle of milling, along with the rubber powder that requires to mill is thin more, the fricative temperature of the micelle that bistrique and elasticity are very strong is just high more, the phenomenon of rubber powder " coking " takes place in regular meeting, causes product to become waste product; In addition, 2. the low temperature mechanical crushing method uses this comminuting method, and pulverizer will be under the low temperature about-120 ℃, will be become the micelle of " vitrifying " state to break into pieces under " brittle temperature " with the strength of hammering mechanical movement.The method of work of this " confronting the tough with toughnees " mechanical crushing causes the life-span of pulverizer hammer to subtract greatly, has shortened service life (being generally about three months).In addition, when pulverizing out fine glue powder, gap between tens motion tups and cavity is very little, under very little gap, " dynamic balancing " between the tup that rotation is got up adjusted very difficult, after processing a period of time, need change one or two new tups, it is just more difficult to adjust " dynamic balancing " again, so this pulverizer also exists fatal shortcoming; 2. the same 1. the same working time of normal temperature mechanical crushing method of low temperature (about 120 ℃) mechanical crushing method is very long, yield poorly, deficiency in economic performance, especially the output to fine glue powder is lower, make domestic still failing so far use fine glue powder well, do not reach the practical requirement of country fine glue powder.And rubber sources is the country of a resource shortage concerning China, need import hundreds of thousands ton virgin rubber every year, how to effectively utilize these waste and used rubber tyres thus and be and concern that China's strategic resource utilizes and prevent to endanger significant problem with contaminated environment again.
The object of the present invention is to provide a kind of with waste and used rubber tyre under accurate cryogenic conditions, by the technology and the method for mechanical crushing, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this: it is mainly formed through preliminary election, cooling, pulverizing by tread rubber, it is characterized in that: after 1. air is compressed into 6-10 atmospheric pressure by air compressor, enter air accumulator, and filter, make oil content＜0.3PPM/CM in the air through air cleaner
3, water content＜1g/M
3, again through the air dryer drying, make dew-point temperature reach-70 ℃, dried clean air through the turbine refrigerator refrigeration, gets accurate Cryogenic air again, and temperature is-5～-35 ℃, and is standby;
2. be purchased clean 8-12 purpose tread rubber,, remove foreign material such as iron filings, earth and fiber hair, be conveyed into the precooling feed bin, and after accurate Cryogenic air cooling, deliver to feed bin through the pipeline blowing through the preliminary election of rubber powder preliminary election machine,
3. in the feed bin again through the cooled tread rubber of difficult Cryogenic air, under accurate Cryogenic air condition, pulverize and sieve through mechanical crusher, wherein 100 purposes reach 10%, 80 purpose and reach 60～70%, 60 purposes reach 15%,＜60 purposes then need repeat processing again.
Its feature also is: described accurate Cryogenic air, its temperature be-and 5-35 ℃.
Its feature also is: described rubber powder preliminary election machine is a reciprocating sieve.The present invention compared with prior art, it is to be to process under-5 ℃～-35 ℃ at accurate low temperature, micelle is a surface embrittlement, micelle hardness increases few, can not produce the phenomenon of " confronting the tough with toughnees ", and is also can Yin Wendu not too high and " coking " take place.The difficulty that it has reduced the rubber powder crushing technology has improved output, and is profitable, is convenient to promote, and can make waste rubber resources obtain rationally utilizing again.
Further specify the present invention below in conjunction with drawings and Examples
Accompanying drawing is a techniqueflow chart of the present invention.
Embodiment
Referring to accompanying drawing, the accurate freeze grinding technology of waste and used rubber tyre of the present invention, it is mainly formed through preliminary election, cooling, pulverizing by tread rubber, at first air is compressed into 6-10 atmospheric pressure by air compressor, then compressed air is sent into air accumulator, and filter through air cleaner, make oil content＜0.3PPM/CM in the air
3, water content＜1g/M
3, again through the air dryer drying, make dew-point temperature reach-70 ℃, dried clean air through the turbine refrigerator refrigeration, gets accurate Cryogenic air again, and temperature is-5～-35 ℃, and is standby; Be purchased clean 8-12 purpose tread rubber, through the reciprocating sieve preliminary election, remove foreign material such as iron filings, earth and fiber hair, be conveyed into the precooling feed bin through the pipeline blowing again, and, be sent to feed bin after the cooling through accurate Cryogenic air cooling, and further cool off through accurate Cryogenic air, cooled tread rubber is pulverized and is sieved through mechanical crusher under accurate Cryogenic air condition, has promptly finished the overall process of the accurate freeze grinding technology of waste and used rubber tyre of the present invention.Wherein 100 purposes reach 10%, 80 purpose and reach 60～70%, and 60 purposes reach 15%, and＜60 purposes then need repeat processing again.
