Silk stock solution is filtered by filtration system, and substantial amounts of scrap rubber can be produced in filter process, and its main component is：Cellulose sulfonic acid
Ester, alkali and carbon disulfide etc.；For scrap rubber, original processing mode is to be directly discharged to the external world, but this processing mode meeting
Surrounding enviroment are caused with serious pollution, while recycling, its economic value can not be carried out to the utility in scrap rubber
It is relatively low.
Usually scrap rubber is mixed with dissolving alkali in the prior art, then dilute glue is generated by the separation of butterfly seperator, then will
Dilute glue and dissolving alkali mixed dissolution cellulose sulfonate, so as to realize the recycling of p-sulfonic acid ester, but its exist with
Lower defect：1st, substantial amounts of hard particles in scrap rubber be present, during butterfly seperator separates scrap rubber, hard particles can be serious
Butterfly seperator is damaged, substantially reduces the service life of seperator, improves production cost；2nd, dilute glue after the separation of butterfly seperator
The swelling body largely formed by hemicellulose and weathering cellulose, in subsequent reactions, swelling cognition and sulphonic acid ester in water be present
With reference to reducing the solute effect of cellulose sulfonate；3rd, its mixed proportion is inaccurate when dilute glue mixes with dissolving alkali, causes molten
The viscose glue alkalinity fluctuation formed after solution sulphonic acid ester is larger, and viscose quality is poor.

In hemicellulose and Peng Runti separated with available dilute glue, then by butterfly seperator and filter by hemicellulose and
Peng Runti is filtered out, and avoids Peng Runti and hemicellulose（It is negatively charged）By dilute glue enter xanthating machine in sulphonic acid ester（With reference to）Shape
Into scrap rubber, the recycling of raw material had both been realized, environment protection treating pressure has been alleviated, reduces production cost again.
2nd, the present invention is provided with static mixer between scrap rubber storage tank and first filter, ensures scrap rubber and alkali lye energy
Enough it is sufficiently mixed, so that the sulphonic acid ester in scrap rubber fully dissolves, so as to lift the quality of final viscose glue finished product；Simultaneously by useless
Glue dilution drum is collected to the scrap rubber after dilution, is on the one hand ensured the stability of subsequent reactions, is on the other hand prolonged
The haptoreaction time of long alkali lye and scrap rubber, lift the quality of product.
3rd, hydrocyclone is provided between first filter of the invention and butterfly seperator, to the hard in scrap rubber
Grain is further filtered, and avoids hard particles from being damaged to caused by butterfly seperator, and extend butterfly seperator uses the longevity
Life.
4th, first filter of the invention is 200 mesh bag filters, ensures the cleaning effect of hard particles, avoids its right
The damage of butterfly seperator, extend the service life of butterfly seperator；Second filter is the bag filter of 150 mesh, is removed
Peng Runti in solution, avoid substantial amounts of Peng Run bodies from combining to form scrap rubber with dissolving sulphonic acid ester, improve the treatment effect of scrap rubber.
