Description
Technical field
The present invention relates to PET bottle and reclaim that field, specifically PET bottle sheet are floating washes dedicated separation bucket.
Background technology
Polyester fiber (polyester fibre) by the polyester of organic dibasic acid and dihydroxylic alcohols polycondensation through the synthetic fibers of spinning gained.The polyester fiber polyethylene terephthalate of industrial mass production is made, the trade name terylene of China.It it is the first big kind of current synthetic fibers.Polyethylene terephthalate is topmost kind in thermoplastic polyester, and English entitled Polythylene terephthalate is called for short PET or PEIT (below or referred to as PET), is commonly called as polyester resin.It is the condensation polymer of p-phthalic acid and ethylene glycol, is referred to as thermoplastic polyester, or saturated polyester together with PBT.PET is divided into fiber polyester chip and non-fiber grade polyester chip.1. fiber-grade polyester is used for manufacturing terylene short fiber peacekeeping polyester filament, is supplied with polyster fibre enterprise processing fiber and the raw material of Related product.Terylene is as the kind of yield maximum in chemical fibre.2. non-fiber level polyester also has the purposes such as bottle class, thin film, is widely used in the fields such as packing business, electronic apparatus, health care, building, automobile, and its intermediate package is the non-fine application market that polyester is maximum, is also the fastest-rising field of PET simultaneously.The PET production scale of China lags far behind external several main manufacturer.Enter the eighties, China progressively goes abroad the advanced PET resin synthesizer of outer introduction ten thousand tons ~ hundreds of thousands ton, quality and yield have had considerable progress, add up according to china textile association, China in 1997 produces PET and cuts into slices 1,740,000 tons, its medium-high viscosity packaging (carafe and package sheet material etc.) section production of resins ability is 22.4 ten thousand tons, so producing the resin source abundance of PET engineering plastics level.Being general owing to preparing the device of various mixture modified PET plastic device and other polymer mixture modifications, the manufacturing industry such as domestic mixture extruder takes on a certain scale, as long as so market is once opened up, the production industry of domestic PET can quickly increase.
Polyethylene terephthalate (PET) is to be generated by polycondensation reaction by a diacid and a glycol.Past production practices use p-phthalic acid two formicester and ethylene glycol produce polyethylene terephthalate as monomer by transesterification and polycondensation reaction.But the polycondensation reaction being increasingly utilized between p-phthalic acid and ethylene glycol in production practices now is to produce polyethylene terephthalate.Reclaiming polyethylene terephthalate is the most successful and most popular example in polymer recovery.At Europe PET bottle recovery always in steady growth.Calendar year 2001, have collected 344000 tons of polyester bottles, increased 20% than 2000.By the end of the end of the year 2006, regeneration association announces Europe 2005 year, and waste PET yield reaches 796000 tons, increases 15.1% than the previous year.The extreme that (regeneration association report, in June, 2006) [5] this waste PET reclaims increase main power is the extensive application of PET, especially in the application of Soft Drinks Plant.One important feature of PET material is that it does not has any side effect for tissue, and this is also that bakery and confectionery selects PET material to be widely used in the decisive reason of commodity packaging.Although it is pointed out that environment is not caused by PET directly to injure, but in view of it account for the sizable part of waste stream, also for air and the high resistance of biotic factor, PET being considered deleterious material.Therefore, recycled PET material is possible not only to solve fraction solids waste problem, it is also possible to save petroleum chemicals raw material and the energy.
In the removal process of PET bottle, particularity due to regenerant, floating washing generally can be used to carry out prerinse, with separate section metal and label etc., now can use the solvent that immiscible two kind density is different, it is usually the combination selecting water with chloroform, so PET bottle sector-meeting swims between water and chloroform, consequently facilitating PET bottle sheet is separated with other impurity ranges, but owing to chloroform price is higher, use common container to carry out flotation and can waste substantial amounts of chloroform, even if all reclaiming, it is also desirable to put into more chloroform.
Summary of the invention
The present invention is just for above technical problem, it is provided that one can facilitate high density impurity flotation, saves again a large amount of high-density solvent, it is also possible to reach the purpose that solvent recycles in a large number, and a bit impregnable the floating of flotation effect washes dedicated separation bucket.
The present invention is mainly achieved through the following technical solutions.
PET bottle sheet is floating washes dedicated separation bucket, including upper barrel body, middle discharging opening, middle staving, lower barrel body, interlayer, lower discharge port, bottom discharge valve, it is characterized in that upper barrel body, middle staving, lower barrel body are sequentially connected with from top to bottom, upper barrel body is cylindrical, upper barrel body bottom is discharging opening in offering with middle staving junction, middle staving and lower barrel body are in the frustum of a cone stood upside down, between middle staving and lower barrel body, interlayer is set, interface channel between middle staving and lower barrel body is controlled switch by interlayer, arranging lower discharge port under lower barrel body, lower discharge port is controlled by bottom discharge valve.Upper barrel body top edge bends inwardly.
Groundwork space of the present invention is upper barrel body, therefore upper barrel body is arranged to cylinder, improve working (machining) efficiency, wherein staving predominantly contains the use of high density container with lower barrel body, therefore the shape of rounding frustum is made, reduce the high-density solvent usage amount of normal and continuous operation, and interlayer is set between middle staving and lower barrel body, can be completely isolated by accommodating between the lower barrel body of high density impurity and middle staving, thus between lower barrel body, pour out high density impurity, and reduce the high-density solvent amount that circulation operation needs to add.
The present invention fully uses the principle of different densities impurity and demixing of solvents, high density impurity and solvent is tapered to certain limit as far as possible, thus decreases the usage amount of high-density solvent, improve the treating capacity of unit solvent, energy-conservation environmental protection again.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is present configuration schematic diagram, wherein:
1 upper barrel body, discharging opening in 2, staving in 3,4 lower barrel bodies, 5 interlayers, 6 lower discharge ports, 7 bottom discharge valves.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
