Abstract

The utility model relates to the field of plastic recycling, in particular to a polycarbonate plastic recovering and recycling device, and is characterized in that the device comprises a washing and mixing kettle, a blowing dryer, a storage tank and a filter, wherein the washing and mixing kettle, the filter and the storage tank are in sealed connection with each other sequentially through pipelines; the washing and mixing kettle is further connected with the blowing dryer through an air pipeline; and a filter screen is also arranged in the washing and mixing kettle. Compared with the prior art, the utility model has the benefits that the processes of washing and mixing during the recovering and recycling process are carried out in the washing and mixing kettle in a centralized manner; as the device is air-proof, the emission of the three wastes is eliminated to meet current environmental protection trend; and the utility model further has the advantages of simple equipment structure, high operability, and low processing cost.

Description

A kind of polycarbonate plastic reclaiming device

Technical field

The utility model relates to plastic reclaimed field, relates in particular to a kind of waste and old polycarbonate plastic reclaiming device.

Background technology

The mankind feel that more and more natural resources is not inexhaustible in evolution, the supporting capacity of ecotope neither be unlimited.Human society will constantly advance, and economy is wanted sustainable development, objectively requires to change growth pattern, explores new Development patterns, reduces the consumption of natural resources and the destruction of the ecosystem.In this case, recycling economy is the inevitable choice of human development.Environment protection and resource recovery are the important contents of building a Harmonious Society as the new industry of China, also are the strategic objectives of 21 century long term growth.

Develop rapidly along with plastics industry, various plastics are applied in fields such as industry, agricultural, health care and the daily life increasingly extensively, the ultimate production of world's plastics surpasses 100,000,000 tons at present, and used waste or used plastics serious environment pollution has become social effects of pollution.As polycarbonate plastic is the manufactured materials of all kinds of household electronic products, automobile, precision meter, light fixture and other civil goods, a large amount of waste or used plastics rubbish of annual thus generation.

Polycarbonate (PC) is maximum in five a big general engineering plastic kind, and the home consumption amount accounted for 54.8% of five big general engineering plastic aggregate consumptions in 2007.The demand of China's polycarbonate turns to fields such as electronics/electric, CD, building, automotive industry by original textile industry spool since phase late 1990s, and demand sharply increases.The home consumption amount was about 140,000 tons in 1999, and consumption in 2003 increases and reaches 380,000 tons, and average growth rate per annum is about about 28%, is higher than the average speed of growth of national economy and the rate of growth of other general engineering plastic far away.Because output in domestic is minimum, the polycarbonate that China uses is mainly from external import.The net importation amount of 1999～2003 years China's polycarbonate is respectively 13.8 ten thousand tons, 23.5 ten thousand tons, 21.2 ten thousand tons, 34.2 ten thousand tons, 38.1 ten thousand tons.China in 2004 polycarbonate import reaches 450,000 tons, just reaches 800,000 tons in 2009, later on also will be with 10%～20% speed increase.As seen a year consumption is huge, therefore also just certainly leads to a large amount of wastes.

At present after the plastics recovery there be renovation process: fusion regeneration, and thermo-cracking, methods such as industrial chemicals and other are reclaimed in energy recovery.

(1) fusion method of reproduction; Fusion regeneration is that waste or used plastics is reheated the method that plastifies and be used.Also cry simple regeneration.This method technology is simple, can't handle the waste or used plastics of degraded and charing.Therefore, quality product is subjected to the influence of supplied materials lower, the use of can only demoting, and the waste water of washing, the waste gas that adds thermogenesis have very big influence to environment.Therefore, utilize factory that this method builds mostly in remote area.

(2) reclaim the heat energy method; Most of plastics are raw material with the oil, and main component is a hydrocarbon polymer, can burn, and the incendiary heat is also higher than right material oil.But, when burning, can produce a variety of toxic gases.This has also caused people from all walks of life's worry, and each country does not support this method for this reason.

(3) thermal-cracking method; Be the hot cracked comburant (-rent) oil that makes of waste or used plastics that will select, the method for fuel gas.This method will be carried out under high temperature, high pressure, to processing requirement, equipment requirements height.Therefore, this technological investment is big, the risk height.This technology just has relevant report very many years ago, but does not also obtain promotion and application always.And the explosion hazard that also has several associated technology to cause.

(4) reclaim the industrial chemicals method; The plastics of some kinds have added the starting monomer when urethane can obtain to synthesize by hydrolysis.This is that a kind of decomposition waste or used plastics that utilizes becomes the method that industrial chemicals reclaims.This method has only Japan, Germany that relevant report is arranged at present also in the elementary experimental phase.

Summary of the invention

The purpose of this utility model provides a kind of polycarbonate plastic reclaiming device, directly utilize the solvent wash dissolving to remove waste and old polycarbonate sheet surface impurity and carbide, the clean materials that obtains adds required toughner, compatilizer etc. after drying up, granulation behind the thorough mixing is reclaimed waste and old polycarbonate plastic and is regenerated.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A kind of polycarbonate plastic reclaiming device, it is characterized in that, comprise washing mixing kettle, hair dryer, storage tank, strainer, washing mixing kettle, strainer, storage tank connect by the pipeline sealing successively, and the washing mixing kettle also is connected by air pipe line with hair dryer.

Pipeline end in the described washing mixing kettle also is provided with filtering net.

Compared with prior art, the beneficial effects of the utility model are: the washing of reclaiming process and mixed processes concentrate in the device and carry out, because device is airtight, therefore do not have three waste discharge, meet current environmental protection trend, device structure is simple, workable, processing cost is low.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

See Fig. 1, a kind of polycarbonate plastic reclaiming device, comprise washing mixing kettle 1, hair dryer 2, strainer 3, storage tank 4, washing mixing kettle 1, strainer 3, storage tank 4 connect by pipeline 5 sealings successively, and the washing mixing kettle also is connected by air pipe line 6 with hair dryer.Pipeline 5 ends in the described washing mixing kettle 1 also are provided with filtering net 7.

The polycarbonate plastic reclaiming is realized by the said apparatus unit, waste and old polycarbonate fragment after will pulverizing is earlier put in the washing mixing kettle 1, be heated to 40 ℃, the combination solvent of ethyl acetate and hexanaphthene is poured in the washing mixing kettle, setting washing mixing kettle 1 stirring rake speed is 32 rev/mins, wash after 20 minutes combination solvent is put into strainer 3 through filter screen 7, returning storage tank 4 by pipeline 5 then recycles, material is after air pipe line 6 usefulness hair dryers 2 dryings, add toughner, compatilizers etc. mix that discharging is finished product after 40 minutes, also can be again through the forcing machine granulation, the utility model biggest advantage is washing procedure and mixed processes unification to be concentrated in the totally enclosed washing mixing kettle carry out, thereby with regard to a large amount of minimizings artificial, reduced cost, realize automatization control easily, do not have three waste discharge, meet current environmental protection trend.
