Description
Technical field
The invention belongs to textile industry viscose glue production technical fields, and in particular to a kind of scrap rubber water sand removing process and system.
Background technique
Currently, yellow process is important one of the production link of viscose glue production industry, and yellow process needs that lye is added
It is dissolved, and KKF in short rayon fiber production process, can generate a large amount of scrap rubbers in sheet frame filter use, containing a large amount of in scrap rubber
Lye, scrap rubber water can substitute lye addition yellow process by purified dilute glue and be dissolved, and then reduce waste, drop
Low production cost, while scrap rubber outlet is reduced, mitigate environmental protection pressure.
But it being contained a large amount of impurities inside dilute glue, population is very high, it can not directly use, thus depth is carried out to dilute glue
Optimization is put into production again in technique, is viscose glue manufacturing enterprise problems faced.What the enterprise of viscose glue preparation at present generallyd use is dilute
Glue is separated through the laggard butterfly seperator of sand cleaning machine, is just directly added into yellow dissolution process, dilute glue made of the method is still
It contains a large amount of impurities, population is also very high, can impact to yellow dissolution process, influence viscose quality.
State Intellectual Property Office discloses a Publication No. CN107881601A on April 6th, 2018, and entitled " one
The patent of invention of kind viscose rayon scrap rubber recovery process ", it is characterised in that：It comprises the following steps that：A, by scrap rubber liquid with it is molten
Alkali is solved according to volume ratio 1:（6-8）Ratio be added in static mixer and form mixed liquor；B, mixed by what is prepared in step A
Conjunction liquid pump, which is sent in filter, to be filtered；It C, will treated that filtrate passes sequentially through hydrocyclone and butterfly by step B
Seperator, the filtrate after separation, which is again fed in filter, filters；D, will through step C treated filtrate and aqueous slkali according to
Volume ratio is 5:3 ratio, which is sent in xanthating machine, reacts.
Recovery process disclosed in above-mentioned document can remove partial impurities, but still have following deficiency：
It 1, cannot be thoroughly except the impurity inside clean dilute glue；
2, the three-level desander desanding capacity used is limited, and impurity content is more in dilute glue, causes seperator pallet, nylon ring
Frequently, maintenance frequently, influences continuous production for damage；
3, the recycling of dilute glue causes viscose glue population high, and spinnability is poor；
4, swelling body is more in dilute glue, and recycling causes filtration difficulty.
State Intellectual Property Office disclosed a Publication No. CN206232870U on 06 09th, 2017, entitled
The utility model patent of " a kind of scrap rubber recycling system ", a kind of scrap rubber recycling system, it is characterised in that：Including KKF
Pre-filtering scrap rubber processing unit, KKF filter scrap rubber processing unit, one of filter device, two filter devices, sheet frame filter together
Scrap rubber processing unit, three filter devices, spinning are for glue bucket and spinning board；KKF pre-filtering scrap rubber processing unit is for handling
Viscose glue passes through the scrap rubber that KKF pre-filtering generates；KKF filters scrap rubber processing unit for handling viscose glue by one of mistake of KKF together
Filter the scrap rubber generated；KKF pre-filtering scrap rubber processing unit and KKF filter together scrap rubber processing unit respectively with filter device together
Connection, one of filter device are connect with two filter devices；The sheet frame filter scrap rubber processing unit is for handling viscose glue process
The scrap rubber that sheet frame filter generates, sheet frame filter processing unit and two filter devices are connect with three filter devices respectively, and three
Filter device and spinning are connected for glue bucket, and spinning is connect for providing viscose glue to spinning board with spinning board for glue bucket.
The scrap rubber recycling system that above-mentioned document provides is optimized, to not in existing scrap rubber recovery system
Use different processing modes with scrap rubber, make scrap rubber degree of ripeness uniformly, population meets production requirement, while being used alone at certain
One region kind avoids mixing with big system scrap rubber and the mass production property spun is caused to influence the quality of high-end product, largely
Solve the problems, such as influence of the scrap rubber of recycling to spinning spinnability.
But in process of production, treated that dilute glue population content is still higher for this system, and in production process
Frequently, maintenance frequently, influences continuous production for middle butterfly seperator pallet, nylon ring damage.
