Description
Technical field
The utility model is a kind of processing unit for KKF backwash viscose glues, and in particular to KKF is anti-in viscose glue production process
The removal of impurities processing unit of viscose glue is washed, belongs to viscose glue processing technology field.
Background technology
Viscose rayon is to glue fine full name it is divided into as viscose filament yarn and short rayon fiber.Viscous fibre is with cotton or other natural
Fiber is the cellulose fibre of raw material production.Its moisture percentage best suits the physiological requirement of human skin, has smooth nice and cool, saturating
Gas, antistatic, the dyeing characteristics such as gorgeous.In viscose rayon production, a variety of solution concentrations, temperature allotment can be related to, needed in technique
Promptly and accurately to realize control targe, it is ensured that subsequent production continuous-stable, it is ensured that product quality reaches standard.Viscose glue production technology
In, sodium cellulose xanghate solution（Viscose solution）Filtering be to ensure that the important step that spinning orderly carries out.Current line is exhausted in the industry
Most of enterprise is filtered using automatic K KF filters, and it is anti-wherein to generate about 5-10% in KKF filters filter process
Wash viscose.The backwash glue has higher economic value, it is necessary to further impurity concentration and glue reuse are carried out to it.
The filtering backwash of KKF filters is substantially to detach the impurity in original viscose solution, concentrate, and impurity will be anti-
It washes in glue and is enriched with, but the backwash viscose still has important utility value and glue is containing high COD, is controlled from cost and environmental protection
Reason is required to recycle viscose solution to greatest extent, reduces impurity treatment cost.Due to the dense height of backwash viscose impurity concentration, viscosity
Height, it is continuous further to recycle viscose and removal of impurities using other filter separation methods.The good and bad of recovery process directly determines material damage
The degree of consumption height and environmental pollution.
Mainly using the filtering of following two backwash glue, recovery process in current industry：
（One）Using polypropylene fibre filter-cloth filtering KKF backwash viscose glues, as shown in Figure 1, by the impurity in all viscoses by filter
Cloth attachment intercepts, and impurity is removed by way of washing cloth, while regenerated filter fabric filtering function.Its technological process is：KKF backwashes
The impurity and portion that viscose glue → deposit glue bucket → polypropylene fibre filter cloth sheet frame filter → viscose recycling bin/polypropylene fibre filter cloth cleaning → polypropylene fibre carries
Viscose glue is divided to enter ejected wash water.
In actual use, it gives up viscose glue due to directly filtering as filter material KKF using polypropylene fibre, it is of high cost with filter material；
Filter cloth need to manually be unpicked and washed without automation mode, the amount of labour is big；Filter cloth easily expends more production water when cleaning；Filter cloth cleaning process
In, the portion adhesive liquid stream carried in filter cloth is lost, and material loss is serious；In filter cloth cleaning process, the viscose glue, miscellaneous of ejected wash water entrainment
Matter is present in water body, and treatment cost is high；It is allocated by pump circulation, it is many that the concentration of lye allotment time is long, fluctuation of concentration is big etc.
Defect.
（Two）It is centrifuged using supercentrifuge, as shown in Fig. 2, the impurity in viscose is made to be acted in centrifugal force
Lower separation realizes that solid impurity is thoroughly isolated, while recycle viscose from viscose solution in scrap rubber.The technological process is：
KKF backwashes glue → and lye 1:8 dilutions → arranged into disk centrifugal separator separation → liquids recovery utilization/solids-enriched slag liquid
It puts.
In actual use, due to directly being detached using centrifuge, the impurity content in backwash viscose glue is higher, directly
Degree of tapping into disk centrifugal separator detaches, and to high-speed centrifuge serious wear, equipment damage is serious, and maintenance cost is high；Centrifugation point
It disembarks after separation clear liquid, the slag liquid of discharge remains as liquid, and processing cost is high.
Existing patent document CN205995140U（A kind of system of lye filtering, 2017.03.08）It discloses to filter bag type
The backwash water of filter and drum body formula automatic filtering machine carries out the technical process of removal of impurities processing, in the filtration system, by filter bag type
The backwash water of filter and drum body formula automatic filtering machine is sent into backwash pond, and backwash water is passed through press filtration by backwash pond connection filter press
Machine, which is filtered to remove after partial impurities, is sent into surge tank, then is filtered by drum body formula automatic filtering machine, due to the use of filtering
System simultaneously differs, and therefore, the processing procedure of the backwash water is not particularly suited for KKF automatic filtering machines.
