Should, solvent for use is nontoxic.
Lyocell fibers are a kind of brand-new weaving, garment material, are risen in middle and later periods the 1990s in America and Europe.It
Not only there is comfort, good hand touch, easy dyeing possessed by natural fiber cotton, also there is traditional viscose rayon institute not
The environmental advantages possessed.Viscose rayon can discharge the pernicious gases such as carbon disulfide, hydrogen sulfide in process of production, pollute environment,
Therefore gradually eliminated in developed country.The pulp that Lyocell fibers are formed after being smashed to pieces using reproducible bamboo and wood etc. is advanced as raw material
Technique causes its solvent recovering rate to be up to 99.5%, not only energy-saving and environmental protection, but also sustainable development.Made of this fiber
Not only gloss nature, slippery feel, intensity are high, substantially shrink-proof for clothing, but also penetrability, good permeability, and wool blended
Fabric effects are good.
In the production process of Lyocell fibers, slurry congee during driving for cleaning system, and normal productive process
Middle reaction kettle and glue pump etc. is sent to produce part scrap rubber, containing cellulose about 11.5% contain solvent about 77% in these scrap rubbers, useless
The generation rate of glue is about 0.8-3%/ton Lyocell fibers.Processing of the existing process to these scrap rubbers is to use plate compression after crushing
Machine is dehydrated, and filter cake aqueous about 30% after dehydration, moisture content is high and wherein still contains solvent 0.3%/ton filter cake, and solvent recovery is not
Thoroughly, and filter cake is manually loaded packaging bag with stainless steel shovel and is put in storage by needs, and the time used in above step is longer, more than repetition
Step is until scrap rubber is disposed, and the time, longer labor intensity was larger.

Steep the return line of groove；The liquid-phase outlet of the plate and frame filter press and centrifuge is respectively communicated with solvent recovery groove.
As a kind of improved technical solution, the import of the scrap rubber soaking compartment is provided with reducing mechanism.
As a kind of improved technical solution, agitating device is equipped with the scrap rubber soaking compartment.
As a kind of further improved technical solution, the shape of the agitating vane of the agitating device is soaked with the scrap rubber
The bottom shape of bubble groove is adapted.
As a kind of improved technical solution, the scrap rubber immersion trench bottom is equipped with one in the entrance of the discharging pump
Concave scrap rubber collection bracket groove.
As a kind of improved technical solution, the plate and frame filter press and centrifuge are equipped with washings inlet pipe.
As a kind of preferable technical solution, the centrifuge is cloth bag centrifuge.
As a kind of improved technical solution, the plate and frame filter press connects described useless with the washing water out of centrifuge
Glue soaking compartment.
By adopting the above-described technical solution, the beneficial effects of the utility model are：
The Lyocell fibers solvent recovery unit of the utility model, including scrap rubber soaking compartment, the scrap rubber soaking compartment go out
Mouth has been respectively communicated with plate and frame filter press and centrifuge by discharging pump；The plate and frame filter press, which is equipped with, connects the scrap rubber soaking compartment
Return line；The liquid-phase outlet of the plate and frame filter press and centrifuge is respectively communicated with solvent recovery groove.In each drive, production
Raw scrap rubber and slurry congee is directly entered plate and frame filter press afterwards in scrap rubber soaking compartment by soaking, after filter-press dehydration, solvent recovery
To solvent recovery groove；The scrap rubber produced in normal productive process enters centrifuge after crushing and immersion, through discharging pump, and centrifugation is de-
Water, the solvent of abjection remove solvent recovery groove.Handled, saved for different scrap rubbers using plate and frame filter press and centrifuge respectively
Processing time has been saved, has alleviated labor intensity, and improve solvent recovering rate.
The utility model is equipped with a concave scrap rubber in the entrance of the discharging pump in scrap rubber immersion trench bottom and concentrates
Groove, it is more thorough in discharging, residual gum material is not had.
The plate and frame filter press of the utility model connects the scrap rubber soaking compartment, filter with the washing water out of centrifuge
Backwash and equipment flushing water all recycle back scrap rubber soaking compartment, avoid solvent loss.
